The lower end of plate, the bottom plate, which is located at probe, is provided with wire guide, and the terminal stud is electrically connected by conducting wire and probe, institute
Conducting wire is stated to be placed in wire guide, the lower end of the bottom plate is provided with extension airbag, the extension airbag be provided with several first
Through-hole, the probe are accommodated in first through hole.
Preferably, cavernous body is filled in the wire guide.
Preferably, a layer insulating is plated on the side wall of the probe.
Preferably, the lower end of the extension airbag is provided with an insulation board, and the insulation board, which is located at first through hole, to be arranged
There is the second through-hole.
As the above scheme is adopted, the chassis of the utility model and the non-integral molding of probe base, utilize the bottom of probe base
Cushion chamber is formed in plate and mounting groove, gives cushion effect using pressure spring, makes probe in detection, cushion effect is provided, hardness is avoided
Contact reduces the excessive damage to probe and pcb board of pressure；Meanwhile probe is stored using extension airbag, prevent outside
Strength gives the effect of guiding to the damage of probe and when pushing probe, and structure is simple, easy to operate, has very strong reality
The property used.
Detailed description of the invention
Fig. 1 is the principle schematic diagram of the utility model embodiment.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in Figure 1, a kind of Novel needle disc structured testing jig provided in this embodiment, it includes chassis 1 and several
Probe base 2, chassis 1 are provided with several mounting grooves 3, and mounting groove 3 is provided with the wiring for connecting external detection analysis instrument
End 9, probe base 2 include bottom plate 4 and several probes 6, and bottom plate 4 is limited in mounting groove 3, the upper end of bottom plate 4 and mounting groove 3
Slot bottom between be provided with several pressure springs 8, probe 6 is installed on the lower end of bottom plate 4, and bottom plate 4, which is located at probe 6, is provided with conducting wire
Hole 13, terminal stud 9 are electrically connected by conducting wire 10 and probe 6, and conducting wire 10 is placed in wire guide 13, the lower end setting of bottom plate 4
There is extension airbag 5, extension airbag 5 is provided with several first through hole 7, and probe 6 is accommodated in first through hole 7.
The chassis 1 of the present embodiment and the non-integral molding of probe base 2, using being formed in the bottom plate 4 and mounting groove 3 of probe base 2
Cushion chamber gives cushion effect using pressure spring 8, makes probe 6 in detection, provides cushion effect, avoids hard contact, reduces pressure mistake
Greatly to the damage of probe 6 and pcb board；Meanwhile probe 6 is stored using extension airbag 5, prevent external strength to probe 6
Damage and the effect of guiding is given when pushing probe 6.
It is different according to the layout of different pcb boards when specific works, then probe base 2, peace are installed in 1 opposite position of chassis
After the completion of dress, then chassis 1 is pushed, pushes entirety to pcb board, then detected.In detection process, at first by stretching
Air bag 12 contacts pcb board, and after continuing extruding, then extension airbag 12 is shunk, and the probe 6 being accommodated in first through hole 7 is then leant out,
It is subsequently inserted on pcb board, continues to push against, at this moment can be given by probe 6 and give thrust between bottom plate 4 and pressure spring 8, and according to pressure
The reaction force of spring 8, then form cushion effect, thus prevent from bringing damage to probe 6, and total during pushing, first through hole 7
Also it is oriented to simultaneously for probe 6.
Further, to prevent the conducting wire 10 during pressure spring 8 is compressed and rebounded, in wire guide 13 and connect
Occur winding between line end 9 and pull, is then filled with cavernous body 14 in the present embodiment wire guide 13, it can be with using cavernous body 14
Conducting wire 10 and the interface of probe 6 are protected, and prevented in buffering course, mutually winds and pulls between conducting wire 10,
In it should be noted that the cavernous body 14 of the present embodiment can also use other materials, such as silica gel, rubber.
Further, to prevent probe 6 during pushing, tip is crimped, and makes occur short circuit between probe 6, therefore.
A layer insulating (not shown) is plated on the side wall of the probe 6 of the present embodiment.
Further, to prevent extension airbag 5 when pushing, appearance position offset, the lower end of the extension airbag 5 of the present embodiment
It is provided with an insulation board 11, insulation board 11, which is located at first through hole 7, is provided with the second through-hole 12, utilizes insulation board 11 and pcb board
It carries out electric signal isolation and gives position restriction when pushing extension airbag 5.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
