Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1-4, the utility model discloses a quick connect fixture convenient to converter test, including spacing couple 20, direction plug-in components 10, press board 40, first needle file 50 and second needle file 51. The first insertion claw 21 is provided on the stopper hook 20, and the first insertion claw 21 is horizontally provided to be inserted into the side hole 72 of the signal terminal block 70. The first insertion claw 21 includes a plurality of first small claws arranged in parallel. The first insertion claws 21 are inserted into the side holes 72, thereby facilitating the fixing of the connecting jig with the signal terminal block 70.

The guide insert 10 is provided with second insertion claws 13, the second insertion claws 13 are vertically arranged to be inserted into the upper holes 71 of the signal terminal block 70, and the first insertion claws 21 are vertically staggered with the second insertion claws 13. The second claws 13 include pairs of second small claws arranged in parallel. The second insertion claws 13 are vertically inserted into the upper holes 71 of the signal terminal block 70. Since the first inserting claws 21 and the second inserting claws 13 are vertically staggered, the signal terminal strip 70 is conveniently fixed with the quick connection jig.

The first needle mount 50 and the second needle mount 51 are fixedly arranged on the guide insert 10. When the first inserting claws 21 and the second inserting claws 13 are inserted into the signal terminal row 70, the probes in the first pin holder 50 and the second pin holder 51 are connected with the signal terminal row 70, so that the quick connection can be realized and the precision is high.
