Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1; The electrical measurement fixture of the utility model comprises the test board 2 that is arranged on the test board 1, place lower platen 3 on the test board 2, parallelly place top board 5 on the lower platen 3, be arranged on the center platen 4 between lower platen 3, the top board 5; Be provided with elastic component spring 7 between center platen 4 and the top board 5, the cover plate 6 that a ribbon gymnastics is made handle is set on the top board 5.When not operating cover plate 6 and pressing down, the distance between top board 5 and the cover plate 6 can be held needs the FPC8 of testing electrical property to push, withdraw from.
Comprise a plurality of positions corresponding pin hole 31, pin hole 41, pin hole 51 on lower platen 3, center platen 4 and the top board 5, be provided with 9, probes 9 of probe in the pin hole and pass pin hole 31, pin hole 41, pin hole 51 in lower platen 3, center platen 4 and the top board 5 respectively.
FPC8 pushes when carrying out testing electrical property, and 81 of conductive electrodes on it are towards top board 5, and locating device limit its each conductive electrode be pushed into just be positioned at top board 5 on the relative position of a plurality of pin holes 51.
Because pin hole 51,41,31 apertures on top board 5, center platen 4 and the lower platen 3 are relatively very little, distance is very near between each hole, therefore; Difficulty of processing increases; And because each hole at a distance of nearer, is prone to when the upper end of adjacent probe stretches out be in contact with one another disturbed test.Therefore, the arrangement mode of preferable pin hole is with the arrangement of staggering of adjacent pin hole, forms two interlaced row's pin holes.
Test process is:
Like Fig. 2, shown in Figure 3; The end of FPC8 with other electronic products such as the pressing of touch-control sensing layer; With FPC another not the pressing end push in the crack between cover plate 6 and the top board 5; 81 of last conductive electrodes of FPC8 are towards top board 5, and locating device limit its each conductive electrode 81 be pushed into just be positioned at top board 5 on the relative position of a plurality of pin holes 51.Operating handle makes cover plate 6 to pressing down FPC8, and FPC8 is affixed on the top board 5 and moves downward with top board 5; Top board 5 compression springs 7; Distance between top board 5 and the center platen 4 is close gradually along with the compression of spring 7; The probe upper end 93 that is positioned at top board 5 pin holes 51 can lean out the upper surface of top board 5 from the hole; Contact connection with the conductive electrode 81 of FPC8 on placing top board 5; Realized test board 2 is communicated with the electrode of FPC8 by probe 9, thereby tested.
As shown in Figure 4, on the basis of embodiment 1, in the present embodiment; With three FPC of pressing on the touch-control sensing layer is example, the position of three FPC that detect according to need, and correspondence is provided with and comprises three detection zones 11 in the electrical measurement fixture; Be to comprise three detection zones 11 on the top board 5, be provided with a plurality of interlaced one-tenth two rows' pin hole 51 in each detection zone 11, be provided with probe in the pin hole 51; All comprise three corresponding detection zones on the center platen corresponding, the lower platen with top board, in each detection zone all correspondence be provided with pin hole, wherein the corresponding detection zone of top board is not to lower recess (drawing among the figure); With ccontaining FPC it is located, to center platen and lower platen structure repeated description no longer, its all the other structures and corresponding relation are identical with embodiment 1 at this; Make electrical measurement fixture carry out testing electrical property to three FPC simultaneously, improved work efficiency.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection domain of the utility model.
