Description
FIELD OF THE INVENTION
[0001] The present invention relates to an anchor structure for
electronic card connectors and particularly to an anchor structure
that can flexibly control fitness of electronic card
connectors.
BACKGROUND OF THE INVENTION
[0002] The progress of electronic information products advances
rapidly these days. Demands of users on electronic products are
higher. Utilization scope of the electronic products is expanded
constantly. Function of electronic products such as computers,
mobile phones, digital cameras and the like also increases. The
auxiliary function also is enhanced. The peripheral electronic
circuits and connection terminals become more complex and
versatile. The connectors generally mean connection elements and
their accessories used to transmit electronic signals and power
supply. They are indispensable elements in the electronic
information products. Their quality not only affects the
reliability of electric current and signal transmission, also
impacts operation quality of the entire electronic equipment.
[0003] A connector generally has an insulation body with fixed pins
formed thereon to be inserted into holding orifices of a circuit
board. The pins are round brass struts or plastic struts. Such a
structure tends to create shaking of the insulation body. It is not
steady or reliable, and not desirable for soldering the connector
pins. Dislocation easily occurs to the insulation body under forces
during insertion or unplugging of external elements. And the pins
of the connector are prone to loosen off and signal transmission
could be impacted.
[0004] FIG. 1 illustrates a connector adopted a conventional
technique. It has a fastening member 3 formed in a round strut to
be inserted into a holding orifice 2 at two ends of a body 1. The
fastening member 3 has a riveting portion 4 exposed outside the
upper edge of the holding orifice 2 to be riveted to form a tight
coupling between the fastening member 3 and the body 1. Then the
body 1 is coupled with an external element (not shown in the
drawing). The external element and the fastening member 3 are
fastened together by screwing (through a fastening element, also
not shown in the drawing). However the conventional technique
previously discussed still has drawbacks, notably: [0005] 1. It
requires a riveting operation in the fabrication process. More
production time is needed. [0006] 2. Riveting operation has to be
performed under a huge force that easily damages the structure of
the body. On the other hand, to do the riveting operation at a
smaller force does not form a strong enough binding, and the body
is easily loosened that could affect the quality of signal
transmission. [0007] 3. Riveting operation forms a fixed coupling
on the holding orifice. It cannot be disassembled and the fitness
cannot be controlled.
SUMMARY OF THE INVENTION
[0008] The primary object of the present invention is to solve the
aforesaid disadvantages. The present invention provides a fastening
element that does not need rivet coupling. Production time can be
reduced. The fastening element has an anchor structure mating a
body to form a secure coupling that is not too tight or too loose.
And it can be flexibly controlled to achieve a desired fitness.
[0009] The anchor structure for electronic card connectors
according to the invention includes an fastening element to be held
in a holding orifice at two ends of a body. The fastening element
has an anchor member and an anchor seat. The anchor member and the
anchor seat have respectively an extended portion formed at a
diameter slightly greater than the fastening element. The anchor
member has a first anchor portion. The anchor seat has a second
anchor portion corresponding to the first anchor portion. The first
and second anchor portions can be coupled together or
separated.
[0010] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Please refer to FIGS. 2, 3 and 4, the anchor structure for
electronic card connectors according to the invention includes a
body 10 and a fastening element 20. The body 10 has a holding bore
11 to hold the fastening element 20. The fastening element 20
includes an anchor member 21 and an anchor seat 22. The anchor
member 21 and anchor seat 22 have respectively an extended portion
210 and 220 that have an outer diameter greater than the fastening
element 20. The anchor member 21 has a first anchor portion 211.
The fastening seat 22 has a corresponding second anchor portion
221. In an embodiment of the invention the first and second anchor
portions 211 and 221 are a C-shaped clip and a groove that mate
each other so that they can be coupled or disengaged with each
other.
[0017] In an embodiment of the invention, the anchor structure is
coupled with a connector 30 and installed at a desired location on
a circuit board 40. The connector 30 is inserted into an orifice 12
to be connected to a pin 13 in the orifice 12. The pin 13 is
connected to the circuit board 40 so that the connector 30 is
electrically connected to the circuit board 40 in a firm manner.
The anchor seat 22 runs through the holding bore 11 of the body 10.
The second anchor portion 221 is exposed outside the holding bore
11 and latched by the first anchor portion 211 of the anchor member
21. Thereby the anchor member 21 and the anchor seat 22 form a
flexible coupling to control fitness of the body 10.
[0018] In addition, the anchor seat 22 has an expanded portion 222
formed at an outer diameter corresponding to the extended portion
220. The expanded portion 222 is annular with a sloped surface to
allow the fastening element 20 to be soldered on the circuit board
40. The holding bore 11 further has an aperture 110 formed at a
greater diameter to house the extended portion 220. The aperture
110 has a plane bucking surface 111. The extended portion 220 has a
tangent surface 223 in parallel with the axis of the anchor seat
22. The bucking portion 111 and the tangent surface 223 form a
confined relationship so that the fastening element 20 cannot
rotate in the holding bore 11. Hence when a screwing element 31 of
the connector 30 is screwed with a bucking hole 224 of the
fastening element 20 the fastening element 20 does not rotate in an
idle manner.
[0019] Refer to FIG. 5 for another embodiment of the anchor
structure of the invention. It differs from the embodiment
previously discussed by having screw threads on the first and
second anchor portion 211 and 221 that mate each other so that they
can be engaged by screwing to form a secure coupling between the
fastening element 20 and the body 10. The anchor seat 22 also has
the same extended portion 220 and expanded portion 222 of the
former embodiment of the invention. And the extended portion 220
also has a tangent surface 223 in parallel with the axis of the
fastening element 20. The anchor member 21 has an extended portion
210 with a bucking cavity 212 formed thereon to be engaged with a
screwing element 31 of the connector 30 (also referring to FIG. 4)
so that when the connector 30 is coupled with the body 10 the
tangent surface 223 can prevent the fastening element 20 from
rotating while the screwing element 31 is screwed in the bucking
cavity 212.
[0020] While the preferred embodiments of the invention have been
set forth for the purpose of disclosure, modifications of the
disclosed embodiments of the invention as well as other embodiments
thereof may occur to those skilled in the art. Accordingly, the
appended claims are intended to cover all embodiments which do not
depart from the spirit and scope of the invention.
