According to the switching device, the liquid crystal module has a small and exquisite structure, the flexible printed circuit board which is difficultly aligned with the test circuit board is connected with the switching board, the test space is expanded, and testing alignment is facilitated, so that the operability of testing caused by the liquid crystal module is improved, particularly, physical damage of the liquid crystal module in an electrical test process can be effectively avoided, and the yield is obviously improved.
Description
Technical field
The utility model relates to a kind of electric circuit inspection of FPC, especially relates to a kind of switching device that is used to test the FPC circuit.
Background technology
It is small and exquisite that the available liquid crystal module has structure, in the Liquid Crystal Module manufacture process, need carry out electric performance test to Liquid Crystal Module.Liquid crystal templated and mainboard connector generally adopts flexible printed circuit board at present.When this Liquid Crystal Module is tested; Flexible print circuit board on this Liquid Crystal Module and the contraposition of measurement circuit plate be difficulty very; And when repeatedly testing, the golden finger on its flexible printed circuit board will stand plug repeatedly, is easy to occur the phenomenon that fractures.
Summary of the invention
The utility model purpose provides a kind of switching device that is used to test the FPC circuit.Solving existing in prior technology contraposition difficulty, golden finger, pin technical matters such as fracture easily.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of switching device that is used to test the FPC circuit; Comprise flexible print circuit board, card extender, measurement circuit plate; Said flexible print circuit board one end is connected with the corresponding connector of Liquid Crystal Module interface, and this flexible print circuit board other end is provided with golden finger; Said card extender one end is provided with pad and pin, and the other end is provided with the diffusion pin, and said measurement circuit plate is provided with pad.
As preferably; Said card extender is a flexible print circuit board, and pad is arranged in parallel on card extender one end, and corresponding with the golden finger on the flexible print circuit board; This card extender other end is an extended pin in one line, and each pin connects through the lead solder joint corresponding with said pad.
As preferably, be respectively equipped with pilot hole on said card extender and the measurement circuit plate, this pilot hole can effectively accurately be located diffusion pin on the card extender and the pad on the measurement circuit plate.
The utility model is small and exquisite and be connected with the utility model card extender with the flexible printed circuit board of measurement circuit plate contraposition difficulty with the Liquid Crystal Module structure; Amplified the test spacing; Made things convenient for the test contraposition; Thereby improved the operability of making the line test at Liquid Crystal Module, particularly can avoid Liquid Crystal Module in the electrical testing process, to cause physical damnification effectively, improved yields significantly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below through embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.
Fig. 1 is the structural representation of the utility model.Can know by Fig. 1; A kind of switching device that is used to test the FPC circuit; Mainly form by flexible print circuit board 10, card extender 11, measurement circuit plate 12 etc.; Said flexible print circuit board 10 1 ends are connected with the corresponding connector 6 of Liquid Crystal Module interface, and these flexible print circuit board 10 other ends are provided with golden finger 4; Said card extender 11 is a flexible print circuit board; Card extender 11 1 ends are provided with the pad 3 that is arranged in parallel; And to pin 7 that should pad 3, this pads arranged parallel 3 is also corresponding with the golden finger 4 on the flexible print circuit board 10, and card extender 11 other ends are extended pins 8 in one line; And be provided with spacing between the adjacent leads 8, each diffusion pin 8 connects with said pad 3 corresponding pins 7 through lead 5.Said measurement circuit plate 12 is provided with pad 9, and card extender 11 is provided with pilot hole 2, and measurement circuit plate 12 is provided with pilot hole 1, and said pilot hole 2, pilot hole 1 can effectively accurately be located diffusion pin on the card extender 11 8 and the pad 9 on the measurement circuit plate 12.
During use, earlier the golden finger 4 of flexible print circuit board 10 1 ends to be tested is connected with pad 3 on the card extender 11, again the diffusion pin 8 of this card extender 11 and the pad in one line 9 of measurement circuit plate 12 is connected, accomplish a testing procedure.Pad in one line 9 with diffusion pin on this card extender 11 8 and measurement circuit plate 12 breaks off then; FPC 10 and card extender 11 are put into next test station; And repeating above step, total interface detects fully and finishes on flexible print circuit board 10.Because the compressing between the pad in one line 9 of the extended pin 8 of card extender 11 and measurement circuit plate 12 contacts reliably, contraposition is easy, has avoided measurement circuit plate 12 directly to contact with FPC 10, has increased the operability of testing to a certain extent.Particularly can avoid effectively in the electrical testing process, causing physical damnification, improve yields significantly.
