Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
See Fig. 1 to Fig. 3, a kind of auxiliary test jig of the present invention, comprise: heaven plate 1, joint pin 2, upper needle plate 3, probe 4, guide pillar 5, end box 6, wherein, heaven plate 1 is connected by joint pin 2 with upper needle plate 3, when the plate 1 that goes up to the sky presses down, as shown in Figure 3, just drive upper needle plate 3 to press down together, realize the test to product.
In order to test products box is accurately located, end box 6 is provided with loading platform 7 and guide hole 8, and product is just positioned on loading platform 7.The periphery that guide pillar 5 is arranged at needle plate 3 matches for guide hole 8, thus realizes positioning function.
Further, in order to improve efficiency and the convenience of test, upper needle plate 3 is also provided with a slide rail 9, slide rail 9 coordinates a slide block 10 slided along it, and slide block 10 installs a sensing chip 11; Loading platform 7 is installed a relay 12, a rotating assembly also installed by end box 6, when slide block 10 forms an avoiding structure 18 to interact with rotating assembly thus to make heaven plate 1 press down, sensing chip 11 contacts with relay 12, successfully can realize test.
Preferably avoiding structure 18 is the fillet that slide block 10 self is formed, and when fillet interacts with rotating assembly thus heaven plate 1 is pressed down, sensing chip 11 contacts with relay 12.
As further improvement, the edge of upper needle plate 3 is also provided with a fixed block 13, is connected one and makes the automatically reset extension spring 14 of slide block 10 between fixed block 13 with slide block 10, after heaven plate 1 rises, slide block 10 will automatically reset under the effect of extension spring 14, for test is next time ready.
