Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a coaxial probe, especially
to a coaxial probe that effectively prevents a probe thereof from
being damaged due to impact force received.
[0003] 2. Description of Related Art
[0004] The design of coaxial terminals provides great convenience
in assembly of two electronic devices. During the assembly of two
coaxial terminals, they may be not assembled correspondingly or
easy get loose after being connected due to size errors or
insufficient mating/unmating force, etc. Refer to Taiwanese Pat.
Pub. No. 1291269 coaxial connector and measuring coaxial probe, a
coaxial probe is disclosed. However, a center conductive probe of
the coaxial probe revealed in the Taiwanese Pat. Pub. No. 1291269
is projecting from the housing and exposed outside. When the
coaxial probe is moved downward to be inserted into a socket
thereunder correspondingly, the center conductive probe exposed
outside the housing is firstly entering the socket. Once a central
hole of the socket is a bit tilted (not aligned), the center
conductive probe receives an impact force firstly. The center
conductive probe is as fine as a needle and is of low structural
strength. The center conductive probe is still tilted or get broken
due to the impact force even there is a coil spring disposed above
the center conductive probe capable of buffering the impact force.
This leads to imprecision of next probing cycle.
SUMMARY OF THE INVENTION
[0005] Therefore it is a primary object of the present invention to
provide a coaxial probe that prevents a probe thereof from being
damaged due to impact force received.
[0006] In order to achieve the above object, a coaxial probe
according to the present invention includes a main sleeve, a
protective sleeve mounted in a sleeve port of the main sleeve and a
probe portion. A leaning flange projecting inward is formed on a
bottom end of the sleeve port of the main sleeve so as to be
stopped and positioned by a stopping flange on an upper part of the
protective sleeve. A connection member is disposed over the sleeve
port of the main sleeve and is used to assemble with a probe of a
probe portion. Moreover, the probe is inserted into a sleeve port
of the protective sleeve and is hidden in the sleeve port of the
protective sleeve. An elastic member for protective sleeves is
arranged between the connection member mounted in the sleeve port
of the main sleeve and the stopping flange of the protective
sleeve.
[0007] Thereby the probe of the coaxial probe according to the
present invention is hidden in the protective sleeve. After the
protective sleeve being in contact with a coaxial connector to be
detected, the probe continues to move and project from the
protective sleeve for detecting the coaxial connector. Thus the
fragile probe will not be affected by the impact force directly and
damages of the probe caused by the impact force can be avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Refer from FIG. 1 to FIG. 3, a coaxial probe of the present
invention mainly includes an assembly base 1, a main sleeve 2, a
protective sleeve 3 a probe portion 4.
[0016] The assembly base 1 is disposed with a threaded segment 11
on an outer wall thereof and a through hole 13 on a center thereof.
A connection disc 12 with a plurality of fastening holes 121 is
arranged at the assembly base 1, under the threaded segment 11.
[0017] The main sleeve 2 is disposed under the assembly base 1 and
a top end of the main sleeve 2 is mounted into the through hole 13
of the assembly base 1. A sleeve port 21 is arranged at a center of
the main sleeve 2. A connection member 22 is mounted in the sleeve
port 21 of the main sleeve 2 and the through hole 13 of the
assembly base 1. An insertion hole 221 is located on a center of
the connection member 22 and a plunger rod 222 is mounted in the
insertion hole 221 of the connection member 22. A connection
segment 223 is formed between the bottom edge of the insertion hole
221 of the connection member 22 and the plunger rod 222. A leaning
flange 23 projecting inward is formed on the bottom end of the
sleeve port 21 of the main sleeve 2. Moreover, an elastic member 24
for main sleeves is arranged around the main sleeve 2 while a top
and a bottom end of the elastic member 24 for main sleeves are
respectively against the bottom of the assembly base 1 and a
step-like flange 25 arranged on an outer wall of the main sleeve
2.
[0018] The protective sleeve 3 is sleeved in a bottom end of the
sleeve port 21 of the main sleeve 2. A stopping flange 31 is
projected from an outer wall on an upper part of the protective
sleeve 3. The stopping flange 31 and the leaning flange 23 on the
bottom end of the sleeve port 21 of the main sleeve 2 are stopped
and positioned by each other. Furthermore, an elastic member 32 for
protective sleeves is arranged between the stopping flange 31 of
the protective sleeve 3 and the bottom end of the connection member
22 mounted in the sleeve port 21 of the main sleeve 2. A guiding
rod 34 is mounted in a sleeve port 33 of the protective sleeve 3. A
guiding hole 341 is arranged at a center of the guiding rod 34 and
a tapered (trumpet-shaped) opening 331 is formed on the bottom of
the sleeve port 33 of the protective sleeve 3.
[0019] The probe portion 4 consists of a probe 41, an axial sleeve
42, and an elastic member 43 for probes. The probe 41 is received
in the guiding hole 341 of the guiding rod 34 of the protective
sleeve 3 and is not exposed. A top end of the probe 41 is inserted
through an axial hole 421 of the axial sleeve 42. A leaning flange
422 projecting inward is formed on the bottom end of the axial hole
421 of the axial sleeve 42. A stopping block 411 is arranged at the
top end of the probe 41. The leaning flange 422 and the stopping
block 411 are stopped and positioned by each other. The top of the
axial sleeve 42 is connected to and assembled with the connection
segment 223 located between the insertion hole 221 and the plunger
rod 222. The elastic member 43 for probes is mounted in the axial
hole 421 of the axial sleeve 42 and a top end of the elastic member
43 for probes is against the plunger rod 222 in the connection
member 22 while a bottom end of the elastic member 43 is against
the stopping block 411 of the probe 41.
[0020] Thereby while being assembled, refer to FIG. 3, the
protective sleeve 3 is firstly mounted into the sleeve port 21 of
the main sleeve 2. Due to gravity, the protective sleeve 3 falls to
the bottom of the main sleeve 2. Thus the stopping flange 31 on the
outer wall of the upper part of the protective sleeve 3 is stopped
and positioned by the leaning flange 23 on the bottom end of the
sleeve port 21 of the main sleeve 2. Then the elastic member 32 for
protective sleeves is mounted into the sleeve port 21 of the main
sleeve 2 and the bottom of the elastic member 32 for protective
sleeves is against the stopping flange 31 of the protective sleeve
3. Next the probe 41 of the probe portion 4 is inserted through the
axial hole 421 of the axial sleeve 42 and the probe 41 also falls
due to gravity. Thus the stopping block 411 on top end of the probe
41 is stopped and positioned by the leaning flange 422 on the
bottom of the axial sleeve 42. Then the elastic member 43 for
probes is set into the axial hole 421 of the axial sleeve 42. The
top end of the axial sleeve 42 is connected to the connection
segment 223 of the connection member 22 and is against the plunger
rod 222 already inserted in the insertion hole 221 of the
connection member 22. Then the probe 41 of the probe portion 4
connected to the connection member 22 is inserted into the guiding
hole 341 of the guiding rod 34 of the protective sleeve 3 and is
not extended from the protective sleeve 3. At the same time, the
bottom end of the connection member 22 is mounted into the sleeve
port 21 of the main sleeve 2 and then the elastic member 24 for
main sleeve is disposed around the main sleeve 2. The top end of
the main sleeve 2 is sleeved into the through hole 13 of the
assembly base 1. The top end and the bottom end of the elastic
member 24 for main sleeve are respectively against the bottom of
the assembly base 1 and the step-like flange 25 of the main sleeve
2 for being positioned. As to the threaded segment 11 and the
connection disc 12 of the assembly base 1, they are used to
assemble with a lift power source.
[0021] While performing quality control detection of a coaxial
connector, refer to FIG. 4, a coaxial connector 5 intended to be
detected is set under the coaxial probe of the present invention.
Then the lift power source connected to the coaxial probe of the
present invention works to move the coaxial probe downward. When
the coaxial probe reaches the coaxial connector 5 being detected,
the tapered opening 331 on the bottom o the protective sleeve 3 is
in contact with the coaxial connector 5 being detected firstly so
as to align the coaxial probe of the present invention with the
coaxial connector 5 being detected. Next by the elastic member 24
between the step-like flange 25 of the main sleeve 2 and the bottom
of the assembly base 1, the direction of a force the lift power
source applied to the assembly base 1 is automatically guided. Thus
the assembly base 1 and the main sleeve 2 assembled with the
assembly base 1 are both moved downward stably. Through the
connection member 22 in the main sleeve 2, the probe portion 4
connected is driven to move downward synchronously. Now refer to
FIG. 5, the elastic member 32 for protective sleeves between the
bottom end of the connection member 22 of the main sleeve 2 and the
stopping flange 31 of the protective sleeve 3 is compressed.
Moreover, the probe 41 of the probe portion 4 is projecting from
the protective sleeve 3 along the guiding hole 341 of the
protective sleeve 3 to be inserted into an insertion hole 51 of the
coaxial connector 5 being detected so as to detect the position of
the insertion hole 51 of the coaxial connector 5 and electrical
quality of electronics therein. Furthermore, by the elastic member
43 for probes located on the rear end of the probe 41 and used for
providing elastic buffer, the probe 41 will not get damaged easily
when the position and straightness of the insertion hole 51 of the
coaxial connector 5 are not correct.
[0022] After the coaxial probe of the present invention completing
detection of the coaxial connector 5 being detected, refer to FIG.
6, the lift power source drives the assembly base 1 connected
thereof to move upward and go back to the original position. At the
same time, the main sleeve 2 connected to the assembly base 1 is
also driven to move upward and go back. Thus the probe 41
originally projecting out of the protective sleeve 3 is retracted
into the protective sleeve 3 gradually. When the assembly base 1,
the main sleeve 2 and the probe portion 4 are turning back upward,
the elastic member 32 for protective sleeves arranged between the
connection member 22 of the main sleeve 2 and the stopping flange
31 of the protective sleeve 3 are also returning to the original
state. Thus the protective sleeve 3 is pushed to move downward so
as to make the probe 41 retract into the protective sleeve 3
completely. Now the coaxial probe of the present invention is ready
for the next detection of the coaxial connector 5.
[0023] In the coaxial probe of the present invention, the probe 41
with low structural strength is mounted in the protective sleeve 3.
When the coaxial probe is moved downward to be in contact with the
coaxial connector 5 thereunder, the protective sleeve 3 is against
and positioned by the coaxial connector 5 to be detected firstly
and then the probe 41 is extended from the protective sleeve 3 to
detect the position of the insertion hole 51 of the coaxial
connector 5 and the electrical quality of electronic components
therein. Therefore the probe 41 will not easily get damaged or
broken due to impact force received and imprecise detection results
can be avoided.
[0024] Additional advantages and modifications will readily occur
to those skilled in the art. Therefore, the invention in its
broader aspects is not limited to the specific details, and
representative devices shown and described herein. Accordingly,
various modifications may be made without departing from the spirit
or scope of the general inventive concept as defined by the
appended claims and their equivalent.
