Detailed description of the invention
In order to more clearly state this utility model, below in conjunction with the accompanying drawings this utility model is further described.
Refering to Fig. 1, pcb board staight needle formula testing jig of the present utility model, including sheet material 1, multiple probe 2, multiple spring 3 and
Spring anchorage bracket 4, sheet material 1 is provided with the through hole 11 of multiple extended probe 2, and forming one between sheet material 1 and spring anchorage bracket 4 can
Place multiple spring 3 and the cavity of multiple probe 2；One end of each spring 3 is separately fixed on spring anchorage bracket 4, and each
The other end of spring 3 is fixing with one end of corresponding probe 2 respectively to be connected, and the other end of each probe 2 can run through corresponding leading to
Hole 11 is connected with the pad of pcb board, and the extended line of each spring 3, corresponding probe 2 and corresponding through hole 11 all with sheet material 1
The plane at place is vertical.
Compared with prior art, pcb board staight needle formula testing jig of the present utility model, it is adaptable to need test on pcb board
The adjacent pad of large pitch, uses this testing jig, and during test, pcb board is directed at this testing jig, it is ensured that pad and corresponding through hole
11 alignments, pcb board is pressed downward against to this testing jig side, and multiple springs 3 shrink so that sheet material 1 subtracts with the spacing of spring anchorage bracket 4
Little, and each spring 3, corresponding probe 2 are all vertical with the plane at sheet material 1 place with the extended line of corresponding through hole 11, therefore
Probe 2 is perpendicular to sheet material 1 and runs through through hole 11 and expose, and with the contact pads on pcb board, it is achieved the short circuit of pcb board or open circuit
Test；And, the sheet material 1 of employing, probe 2, spring 3 and spring anchorage bracket 4 testing jig compared to existing technology, the material of employing
Few, test result is accurate.Pcb board staight needle formula testing jig of the present utility model, have test accurately, save material, easy to use
And the feature of testing efficiency can be improved.
In the present embodiment, in cavity, also set the backing plate 5 for regulating probe 2 height, and backing plate 5 is run through in one end of probe 2
Fix with the other end of spring 3 and be connected.The height of backing plate 5 can adjust so that probe 2 stretches out the part scalable of through hole 11.
In the present embodiment, a diameter of 0.55 millimeter of spring 3, a diameter of 0.65 millimeter of through hole 11, and every phase on pcb board
The spacing of adjacent two pads, the spacing of the most adjacent corresponding two springs 3, the spacing of the most adjacent corresponding two probes 2 and right
The spacing of the most adjacent two through holes 11 answered is more than 0.15 millimeter.The spring 3 of 0.55 mm dia so that two identical springs
Spacing between 3 is at least 0.15 millimeter, it is to avoid the space flicked after spring 3 compression is too small, and therefore the spacing of through hole 11 is necessary
Be more than 0.15 millimeter so that corresponding probe 2 spacing and corresponding spring 3 spacing all with the spacing one of adjacent two through holes 11
Cause.
