Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This is a continuation application of International Patent
Application No. PCT/CN2013/081798, filed on Aug. 19, 2013, which
claims priority to Chinese Patent Application No. 201320075344.X
filed on Feb. 18, 2013, the disclosure of which is incorporated by
reference herein in its entirety.
TECHNICAL FIELD
[0002] The disclosure relates to communications technology, and
more particularly, to an optical fiber connector assembly, an
optical fiber connector plug, and an adapter assembly.
BACKGROUND
[0003] With development of optical fiber communications, there are
numerous optical fibers and optical cables to be arranged in a
communication network. Connection states, connection relationships
and smart management of the optical fibers and optical cables
become more and more important in the face of large scale massive
fiber optical networks, a great variety of optical wiring
equipments, frequent and urgent on-off for optical fiber networks,
and maintenance requirements from customers. Therefore, an optical
fiber connector, as an important unit of connection among the
optical fibers and the optical cables, also gets more and more
attention.
[0004] Currently, there are many types of universal optical fiber
connectors in the optical fiber network, such as a Square Connector
(SC), a Lucent Connector (LC), a Ferrule Connector (FC), a Stab
& Twist (ST) connector and etc. The SC type of optical fiber
connector has a rectangular shell, and is fixed in a plug-pull
coupling way. A guide raised key with a semi-circular front end and
a square back end is on a side of a shell of the SC type of optical
fiber connector plug. A convex shape of bayonet window is on each
of two sides of the guide raised key. This bayonet window is
composed of two arc invaginated outer shell guide rails and one
inner shell boss. The SC type of adapter has symmetrical guide
grooves at two ports and two bayonet barbs with a cylindrical pin
abutting cavity between them. When the guide raised key on the SC
type of optical fiber connector plug is inserted into the SC type
of adapter along the guide grooves of the SC type of adapter, the
bayonet barbs in the SC type of adapter may hook the bosses in the
bayonet windows of the SC type of optical fiber connector plug,
thereby locking the SC type of optical fiber connector plug and the
adapter. When the guide raised key on the SC type of optical fiber
connector plug is pulled out of the adapter along the guide grooves
of the SC type of adapter, the arc guide rails on the bayonet
windows on two sides of the SC type of optical fiber connector plug
slowly support the bayonet barbs in the SC type of adapter, and
thus the bayonet barbs are broken away from the bosses in the
bayonet windows of the SC type of optical fiber connector plug,
thereby separating the SC type of optical fiber connector plug from
the adapter. The LC type of optical fiber connector adopts an
operation modularization snap coupling mechanism. The FC type of
optical fiber connector adopts a metal ferrule for outside
enhancement, and is fixed in a screw coupling way. The ST type of
optical fiber connector has a circular shell, and is fixed in a
screw coupling way.
[0005] When the universal optical fiber connector such as the SC,
the LC, the FC, the ST, and etc., is used in the same network for
connection among optical fibers and optical cables, the shape, the
colour, the structure, and the like of the optical fiber connector,
the adapter, the optical cable, and etc. are almost the same.
Meanwhile, in most of current identification methods, a paper or
plastic label is used and fastened to an optical cable or a tail
end of a joint by means of glue or a fixation string. Because of
connection environment, frequent operation and maintenance as well
as time lapse, an attached label is easily fell off and/or aged.
Further, it may be identified by mistake, and may not be dealt with
in time on scene, and therefore this method cannot achieve
effective identification on a link or a port. Moreover, during the
start-up and maintenance process, there is no accurate connection
indication between the ports. It is easy to insert a wrong plug.
Once the plug is falsely inserted, it is very difficult to find
out.
[0006] Currently, there is a new connector assembly for preventing
false insertion on the market. This assembly has a plug opening for
accommodating a front end of the optical fiber connector plug. The
front end of the optical fiber connector plug has a plug section
for matching with the plug opening. A plug information storage chip
is fixedly arranged on the optical fiber connector plug. All pins
of the plug information storage chip are electrically connected to
metal conductors. A metal elastic member touching against the metal
conductors when plugging is provided on the optical fiber connector
adapter. The metal elastic member is used to electrically connect
to a signal input end of a system main board. An indicator light is
further provided on the optical fiber connector adapter, and is
used to electrically connect to a signal output end of the system
main board. When plugging, plug information in the plug information
storage chip is input to the system main board through metal
conductors and the metal elastic member. If the information is
matched, then the indicator light is lightened; otherwise, the
indicator light is not lightened. Thus, false insertion is
prevented between two or more optical fiber connector
assemblies.
[0007] However, this method for preventing false insertion requires
a plug member which can match with the universal SC type and/or LC
type plugs, and thus such a structure is relatively complicated.
Meanwhile, the indicator light of the adapter is subject to be
blocked by an optical fiber, and an indication effect is bad. In
addition, in-position information detection cannot be performed on
a traditional SC, and thus a plug of a non-matched SC cannot be
identified.

[0057] FIG. 18 is a top view of a base plate for an optical fiber
connector adapter having a printed circuit according to an
embodiment of the disclosure. FIG. 19 and FIG. 20 are an assembly
top view and an assembly front view of the optical fiber connecter
adapter and a printed circuit board according to an embodiment of
the disclosure, respectively. As shown in FIG. 18 to FIG. 20, pin
contacts 32 and an indicator light 31 are provided in parallel on
the adapter base plate 130. The pin contacts 32 are connected to an
input end of an external microprocessor, and the indicator light 31
is connected to an output end of the microprocessor.
[0058] As shown in FIG. 1 to FIG. 20, when the optical fiber
connector adapter 120 is installed on the adapter base plate 130,
the indicator light 31 is accommodated in an indicator light
accommodation portion 22 and the metal elastic pins 18 are
electrically connected to the pin contacts 32. When the optical
fiber connecter plug 110 is inserted into the optical fiber
connector adapter 120 installed on the adapter base plate 130, the
metal elastic pins 18 are electrically connected to the conductive
slide rails 14, the indicator light-guiding pillar 1 is inserted
into the indicator light accommodation portion 22, and abuts
against the indicator light 31.
[0059] Based on the above main body structure, the disclosure is
further explained below in detail in combination with the
accompanying drawings and specific embodiments.
[0060] Preferably, in this embodiment, in the optical fiber
connector plug 110, the plug information storage chip 12 and the
conductive slide rails 14 are provided on a printed circuit board
13 on the bottom side of the optical fiber connector plug, wherein
the plug information storage chip 12 is deployed on one side of the
printed circuit board 13, and the conductive slide rails 14 are
deployed on the other side of the printed circuit board 13, and the
pins of the plug information storage chip 12 are electrically
connected to the conductive slide rails 14 through the printed
circuit board 13.
[0061] Preferably, in this embodiment, an invaginated hollow boss 7
is provided on the bottom side of the optical fiber connector plug
110, the printed circuit board 13 deployed with the plug
information storage chip 12 and the conductive slide rails 14 is
fixed in the hollow boss 7.
[0062] Preferably, in this embodiment, invaginated guide slots 11
are provided on the hollow boss 7 at positions which match with the
conductive slide rails 14, and are used to guide the metal elastic
pins 18 to abut against the conductive slide rails 14, when the
optical fiber connector plug 110 is inserted into the optical fiber
connector adapter 120.
[0063] Preferably, in this embodiment, the optical fiber connector
plug 110 includes a plug shell 5. Both the hollow boss 7 and the
indicator light-guiding pillar 1 are provided on the plug shell 5.
Alternatively, the hollow boss 7 is provided on the plug shell 5,
and the indicator light-guiding pillar 1 is fixed on a sheath 2 of
the plug.
[0064] Herein, when the light-guiding pillar is provided on the
plug shell 5, an end of the light-guiding pillar protrudes from a
lower side of the shell of the connector plug, and the other end of
the light-guiding pillar extends to a tail end of a shell of an
adapter. As such, this light-guiding pillar can transmit the state
of the indicator light at the front end of the plug from the
printed circuit on the adapter base plate to the tail end of the
sheath of the plug.
[0065] Preferably, in this embodiment, the metal elastic pins 18 in
the optical fiber connector adapter which are used to scratch and
insert into the conductive slide rails 14 preferably have
small-angle corners folded at positions of scratching and inserting
into the conductive slide rails so as to facilitate point contact
with the conductive slide rails; and large-angle corners folded at
positions of contacting with the adapter bottom cover plate so as
to increase upright elastic force of the pins.
[0066] Preferably, in this embodiment, a plug in-position detection
portion 30 is further provided on the adapter base plate 130 and is
connected to the input end of the microprocessor. A reservation
hollow 19 is further provided on the optical fiber connector
adapter 120. When the optical fiber connector adapter 120 is
installed on the adapter base plate 130, the plug in-position
detection portion 30 enters the optical fiber connector adapter 120
through the reservation hollow 19. When the optical fiber connector
plug 110 is inserted into the optical fiber connector adapter 120,
the plug in-position detection portion 30 is triggered.
[0067] In this embodiment, the in-position detection potion 30 is
provided to prevent a false insertion of a traditional optical
fiber connector plug into the adapter 120. Specifically, when the
plug normally provided with the plug information storage chip is
inserted into the adapter, the microprocessor detects two signals.
One is plug information transmitted from the chip, and the other is
plug in-position information transmitted from the plug in-position
detection portion 30. At this time, the microprocessor may usually
determine whether the false insertion is prevented. However, when
the traditional optical fiber connector plug is inserted into the
adapter, since there are no chip-level conductive slide rails
provided in the traditional plug, the microprocessor can only
detect that the plug is inserted at this time, and thus can
determine that this plug must be wrongly inserted. At this time, a
false insertion alarm may then be sent by controlling an indicator
light so that a false insertion of a non-matched plug is
prevented.
[0068] Herein, the plug in-position detection portion 30 may be but
not limited to a detection flicking needle or a microswitch.
[0069] Preferably, in this embodiment, the microprocessor may be
placed in a wiring equipment or an external module. The
microprocessor is one or more circuits, one or more chips or one or
more devices, which transmits a signal for activating or
"stimulating" an Electrically Erasable Programmable Read-Only
Memory (EEPROM) chip, and receives and decodes information from the
activated EEPROM chip. The microprocessor may include a single
circuit, chip or device, or may include multiple circuits, chips
and/or devices.
[0070] Preferably, in this embodiment, the plug information storage
chip 12 is preferably an EEPROM chip since the EEPROM chip does not
lose data after outage. The information on the EEPROM chip may be
erased by means of a computer or dedicated equipment, and may be
re-encoded. Thus, its application is very flexible and wide.
[0071] Based on the above architecture, in this embodiment, an
implementation process for the optical fiber connector assembly to
prevent a false insertion in a specific application includes the
following steps.
[0072] Step 1, a printed circuit board provided with the EEPROM
chip is fixed on the hollow boss on a side of the optical fiber
connector. The printed circuit board provided with the EEPROM chip
includes a micro EEPROM chip, a small printed circuit board, and
guide slide rails on the printed circuit board. The printed circuit
board can be fixed into the hollow boss of the optical fiber
connector plug by building-in, plugging on the side, welding or
super glue. The printed circuit board provided with the EEPROM chip
is installed in this hollow boss so that a side of the printed
circuit board with the chip faces an inner side of the optical
fiber connector plug, and two guide slide rails provided by the
printed circuit board are installed on an outer side of the hollow
boss.
[0073] Step 2, when plugging, after two guide slide rails of the
printed circuit board provided with the EEPROM chip on the optical
fiber connector plug are connected to a peripheral microprocessor
through scratching and inserting of metal elastic pins in the
optical fiber connector adapter, a pin of the indicator light of
the printed circuit board on the adapter base plate is also
connected to the microprocessor at the same time. An operator
performs reading and/or writing operations on a chip on this
optical fiber connector plug via the microprocessor and a control
system, and performs lightening scan through the indicator lights
of the printed circuit board on the adapter.
[0074] Step 3, the indicator lights of the printed circuit board on
the base plate of the optical fiber adapter are lightened according
to a pre-set connection relationship, to guide the optical fiber
connector plug to insert. The indicator light after plugging is
displayed at a tail end of the connector plug via the light-guiding
pillar. If there is a false insertion, the corresponding indicator
light is kept lightened. If the connection is wrong, then the
indicator light is not lightened.
[0075] Step 4, once all of the chips provided with the EEPROM chip
in a wiring system are successively activated, all the connections
of jumper wires or tail fibers in the entire wiring system will be
identified. This information may be for example stored in a
database, displayed on a computer screen, printed in a report, and
etc. Thus, intelligent and electronic management of an optical
fiber connector port is implemented.
[0076] In order to further explain the technical solutions provided
by the embodiments of the disclosure, the optical fiber connector
assembly according to the disclosure is further explained below in
combination with structural schematic views of an optical fiber
connector plug and an optical fiber connector adapter.
[0077] An optical fiber connector assembly is provided in this
embodiment for port identification and positioning, and includes an
optical fiber connector plug, an optical fiber connector adapter,
and an adapter base plate.
[0078] As shown in FIG. 1 to FIG. 20, the optical fiber connector
plug 110 includes a light-guiding pillar 1, a sheath 2, a plug
shell 5, a ceramic pin 9, a pin dustproof cap 4, an EEPROM chip 12
and a printed circuit 13.
[0079] The light-guiding pillar 1 is embedded in the plug shell 5
of the optical fiber connector plug, and extends to a front side of
the plug shell 5. When the optical fiber connector plug is inserted
into the optical fiber, connector adapter, the light-guiding pillar
is inserted into an indicator light reservation position 22 on the
adapter so as to export a light signal of the indicator light after
the indicator light 31 on the adapter base plate is accommodated in
the indicator light reservation position 22.
[0080] The pin dustproof cap 4 covers a head of the pin 9, and is
used to protect an end surface of the pin 9. The plug shell 5
covers a main body of the pin 9 and may slightly slide on the main
body of the pin 9. A raised key having a circular front end and a
square back end is provided on one side of the plug shell 5. This
raised key is a guide key 3, a width and a length of which is
suitable for abutting, guiding and positioning of the optical fiber
connector plug. There is an inverted "convex" shaped bayonet window
on each of two sides of the guide key 3. There are two invaginated
shell arc guide rails 6 with and a pin main body inner shell boss 8
in each bayonet window. When the optical fiber adapter plug is
inserted, the plug shell 5 slides along the main body of the pin 9
towards the sheath 2, and thus the pin main body inner shell boss 8
may be exposed for latch of the connector.
[0081] One side of a chip printed circuit board 13 is welded with
an EEPORM chip 12. One of two welding contacts is a data
transmission pin of the EEPORM chip 12, and the other one is a
ground pin. These two pins are connected to conductive slide rails
10 on the other side of the printed circuit board 13 through a
soldering tin hole 14 of the chip printed circuit board 13. The
chip printed circuit board 13 assembled with the EEPORM chip 12 is
installed in a hollow boss 7 of the optical fiber connector plug.
This hollow boss 7 is provided on a side opposite to the guide key
3, close to one edge, while a light-guiding pillar 1 is provided on
the other edge, so as to form a structure that the hollow boss 7
and the light-guiding pillar 1 are provided in parallel on the side
opposite to the guide key 3. With regard to the hollow boss 7, an
outer part of a rectangle opening is big, and an inner pad of the
rectangle opening is small. There is a barrier plate in the opening
near the inner shell boss. There are two micro invaginated guide
slots 11 on an outer surface edge of this boss along with the guide
key 3. A structure of this hollow boss may causes it to be closely
installed with the printed circuit board 13 provided with the
EEPROM chip. Moreover, the invaginated guide slots 11 may guide the
elastic pins in the optical fiber connector adapter to increase
accuracy of scratching and inserting. The structures of the
light-guiding pillar 1 and the hollow boss 7 on the optical fiber
connector plug 110 provided with the EEPROM chip also fit the
described boss structure of the indicator light reservation
position 22 on the adapter which, as a light reservation position
on the optical fiber connector adapter 120, accommodates the
indicator light 31 on the printed circuit board of the adapter base
plate. In addition, this boss structure may guarantee the indicator
light 31 on the printed circuit board of the adapter base plate to
transmit an identification signal to an optical fiber connector
plug shell 5 through the light-guiding pillar 1 on the connector
plug shell. The printed circuit board 13 provided with the EEPROM
chip is fixed on the hollow boss 7 on the optical fiber connector
plug through welding or super glue, wherein the EEPROM chip 12
faces an inner side of the optical fiber connector plug shell 5. On
the other side, the conductive slide rails 10 and the invaginated
guide slots 11 form a slide trace of the elastic pins 18 of the
optical fiber connector adapter.
[0082] The optical fiber connector adapter 120 is mainly composed
of an optical fiber connector adapter dustproof cap 15, an adapter
housing 29, a bottom cover plate 16, an indicator light reservation
position 22, an in-position detection flicking needle (or a
microswitch) reservation hollow 19, chip metal elastic pins 18, two
bayonet barbs 23, and a cylinder pin guide cavity 24.
[0083] The adapter dustproof cap 15 implements seal protection on a
port of the adapter through a raised key on the dustproof cap and
an inner rib. A cylinder guide pillar 21 and an elastic fixation
pin 17 on a polygon housing bottom cover plate 16 are used to fix
the optical fiber connector adapter, and the cylinder guide pillar
21 is used for position limitation and guiding before fixation.
There is a horizontally squeezed deformation design on a swapping
head of the elastic fixation pin 17 so as to facilitate fixation
and detachment between the elastic fixation pin 17 and a plug
plate.
[0084] There is an optical fiber connector adapter guide groove 14
in an opening at each of two ends of the optical fiber connector
adapter 120, a length and a width of which are suitable for guide
and position limitation on a guide key 3 of the optical fiber
connector plug 110 during a swapping process. The cylinder guide
pillar 21 and the elastic fixation pin 17 are fixed on a movable
polygon housing bottom cover plate 16 which can be fixed on a lower
surface of the optical fiber adapter through super glue or a
wilding machine. Before the cover plate is fixed, a housing guide
cavity 24 and two bayonet barbs 23 in the optical fiber connector
adapter may be assembled into an adapter cavity through this
window. Moreover, an I-shaped boss 26 is positioned on a surface of
the polygon housing bottom cover plate 16 opposite to the pin 17,
and is used to support positions of the adapter guide cavity 24 and
bayonet barbs 23. Guide slots and holes of the metal elastic pins
18 used for scratching and inserting the conductive slide rails of
the EEPROM chip 12, and position limitation guide grooves 28 at
head ends of the elastic pins, are distributed on two sides of the
I-shaped positioning boss 26 on the polygon housing bottom cover
plate 16. The metal elastic pins 18 are fixed on the polygon bottom
cover plate through the guide slots and the holes via mechanical
bayonets of the guide slots or the super glue. The indicator light
reservation position 22 is fixed through a light hole on the bottom
cover plate. The indicator lights 31 on the adapter base plate are
positioned on two ports of the optical fiber connector adapter 120
through the adapter bottom cover plate and an adapter edge
invaginated guide slot 27.
[0085] In the optical fiber adapter 120 according to the
disclosure, a skylight opening of the polygon housing bottom cover
plate 16 faces openings of the ports on two sides, and is used for
fixation of the indicator light 31 on the printed circuit board of
the adapter base plate and compatibility with a traditional SC
shell. The skylight opening of the polygon housing bottom cover
plate 16 forms a right-angle corner on a plane of the adapter
elastic fixation pin 17, and is invaginated on a side of the
optical fiber connector adapter 120, which guarantees position
limitation and fixation of the polygon housing bottom cover plate
16 on the front, back, left, and right. Two bayonet barb guide
slots are formed in two inside walls of the optical fiber connector
adapter 120. The skylight opening of the polygon bottom cover plate
may be accurately installed with the bayonet barbs and a cylinder
pin abutting cavity.
[0086] As shown in FIG. 18 to FIG. 20, the printed circuit board on
the adapter base plate 130 includes the connector plug in-position
detection flicking needle 30, an indicator light 31 and pin
contacts 32. In the drawing, the indicator light 31 may be a
surface mount indicator light welded on the printed circuit board
of the base plate, and the connector plug in-position detection
flicking needle 30 (or a microswitch) is also welded on the printed
circuit board. The indicator light 31 and the in-position detection
flicking needle 30 are installed in the optical fiber adapter
through an in-position detection flicking needle (or the
microswitch) reservation hollow 19 (as shown in FIG. 19).
[0087] Specifically, when plugging, the optical fiber connector
plug 110 provided with the EEPORM chip is first inserted into a
port on one side of the optical fiber connector adapter 120. When
the guide key 3 on the optical fiber connector plug 110 is inserted
into the adapter along the guide groove 14 of the optical fiber
connector adapter 120, the shell 5 on the optical fiber connector
plug 110 moves towards the sheath 2 and thus the pin main body
inner shell boss 8 may be exposed. Further, two bayonet barbs 23 on
the optical fiber connector adapter 120 are locked into the pin
main body inner shell boss 8 along two invaginated shell arc guide
rails 6 in the bayonet window. The light-guiding pillar 1 on the
optical fiber connector plug shell is also inserted into the
indicator light reservation hole 22 along with the connector shell
5, and abuts against the indicator light 31. At the same time,
protruded portions of the metal elastic pins 18 on the bottom cover
plate of the optical fiber connector adapter scratches the
conductive slide rails 10 on one side of the printed circuit board
13 provided with the EEPORM chip 12 on the optical fiber connector
plug along the invaginated guide slots 11 on the hollow boss of the
optical fiber connector adapter plug. The optical fiber connector
pin 9 is inserted in a cylinder pin guide cavity 24 of the optical
fiber adapter, and latch between the optical fiber connector plug
110 and the optical fiber connector adapter 120 is implemented.
During the process of pulling out, when the guide key 3 on the
optical fiber connector plug is pulled out of the adapter along the
guide grooves 14 of the adapter, the shell 5 on the optical fiber
connector plug slides far from the sheath 2, and two bayonet barbs
23 on the optical fiber connector adapter slide far from the sheath
2 along two invaginated shell arc guide rails 6 in the bayonet
window. Because a sliding direction is from a low position to a
high position of two invaginated shell arc guide rails 6, bayonet
portions of two bayonet barbs 23 are jacked up by the high position
of the invaginated shell arc guide rails 6 and the bayonet portions
of two bayonet barbs 23 are broken away from the pin main body
inner shell boss 8. The light-guiding pillar 1 on the optical fiber
connector plug shell is also pulled out of the indicator light
reservation hole 22 along with the connector shell 5, and thus the
light-guiding pillar 1 and the indicator light 31 are separated.
Simultaneously, protruded portions of the elastic pins 18 on the
bottom cover plate of optical fiber connector adapter slide out of
the conductive slide rails 10 on one side of the printed circuit
board 13 provided with the EEPORM chip 12 of the optical fiber
connector plug 110 and the invaginated guide slots 11 on the plug
hollow boss 7 of the optical fiber connector adapter 120. The
optical fiber connector pin 9 is broken away from the cylinder pin
guide cavity 24 of the optical fiber adapter, and thus the optical
fiber connector plug 110 is pulled out of the optical fiber
connector adapter 120.
[0088] In conclusion, the disclosure provides an optical fiber
connector assembly which contains an optical fiber connector plug
provided with a plug information storage chip (for example, the
EEPROM chip) and the indicator light-guiding pillar, an optical
fiber connector adapter provided with the elastic metal pins and
the indicator light accommodation portion, and the adapter base
plate provided with the indicator light and the pin contacts.
[0089] In the assembly, the optical fiber connector plug provided
with the EEPROM chip is similar to a universal SC joint structure
in that there is a guide raised key on one side of the plug shell
with a semi-circular front end and a square back end. There is a
"convex" shaped bayonet window on each of two sides of the guide
raised key and this bayonet window is composed of two invaginated
shell arc guide rails and an inner shell boss. A difference lies in
that there is a rectangle hollow boss on a side opposite to the
side in which the guide key is located, and an outer part of the
rectangle opening is big while an inner part of the rectangle
opening is small. There is a barrier plate in the opening near the
inner shell boss. Two micro invaginated guide slots are positioned
on an outer surface of this step in a direction of the guide raised
key. The printed circuit board provided with the EEPROM chip is
installed in this hollow boss. The side of the printed circuit
board with the chip faces an inner side of the optical fiber
connector plug, and two conductive slide rails provided by the
printed circuit board are installed on an outer side of the hollow
boss. Before installation, this EEPROM chip is welded on one side
of the rectangle printed circuit board, and a data pin and a ground
pin are connected to two conductive slide rails on the other side
through the printed circuit board. On the side in which an EEPROM
chip slot position is located, a base plate provided with the
indicator light-guiding pillar is protruded from a connector plug
shell (or a connector sheath, a shell is used below). The
light-guiding pillar at one end of this base plate is protruded
from the connector plug shell and the light-guiding pillar at the
other end extends to a tail end of the connector shell.
[0090] There are symmetric guide grooves at two plug openings of
the optical fiber connector adapter, and there are two bayonet
barbs in the adapter with a cylinder pin abutting cavity between
them. There is a polygon bottom cover plate on an outer side of the
adapter opposite to the guide grooves. Adjacent edges of the bottom
cover plate at the optical fiber connector adapter port are
invaginated towards the adapter to form the opening, and there are
two clamping jaws used to fix the printed circuit board of the
adapter base plate in the polygon bottom cover plate and an
adjacent adapter. There is a "convex" shaped boss in the middle of
an upper side of the polygon bottom cover plate. The metal elastic
pins which are used to contact the EEPORM chip, and the hollow
which is used to accommodate the indicator light and the connector
plug in-position detection flicking needle (or the microswitch)
fixed by the printed circuit board of the adapter base plate, are
fixed on two sides of the boss. There are two guided pillars
respectively on two sides of a centre line on a bottom side of the
polygon bottom cover plate. Through this polygon bottom cover
plate, the bayonet barbs and the cylinder pin abutting cavity may
be installed in the optical fiber connector adapter, and then the
optical fiber connector adapter is installed on the adapter base
plate provided with the plug in-position detection flicking needle
(or the microswitch), the indicator light, and a microprocessor
connection pin. When inserted into the adapter, the optical fiber
connector plug contacts an adapter chip contact metal flicking
needle and the in-position detection flicking needle (or the
microswitch) through the EEPORM chip and a plug side to perform
identification of the optical fiber connector plug, and displays
indicator light information provided on the printed circuit board
of the adapter base plate on the optical fiber connector plug.
