Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 3, a push-pull single-clamp-head fast power cable connection device mainly comprises an insulating shell 1, a scissor fork fixing pin 2, an upper scissor fork tightening rod 3, a lower scissor fork tightening rod 4, a push-pull rod fixing pin 7, a cable 8 and a handle type push-pull rod 9.

Two terminal surfaces are opened around insulating housing 1 for upper scissors fork clamping rod 3 and lower scissors fork clamping rod 4 pass. Adopt scissors fork fixed pin 2 to fix in insulating casing 1 front portion, go up scissors fork and add the pole 3 and cut fork and add the pole 4 with down and all rotate and connect on scissors fork fixed pin 2, form scissors fork mechanism. The pull rod fixing pin 7 is fixed at the rear part of the insulating shell 1, and the middle part of the handle type push-pull rod 9 is rotatably connected to the push-pull rod fixing pin 7. The handle of handle formula push-and-pull rod 9 upper end stretches out 1 top surfaces of insulating housing, and the lower extreme is equipped with the recess of accomodating upper scissors fork and adds the tight pole 3 and cut fork and add tight pole 4 down. Go up and cut fork 3 afterbody and be equipped with first guide arm 5, cut fork 4 afterbody down and be equipped with second guide arm 5, the lateral wall of the recess of handle formula push-and-pull rod 9 lower extreme is equipped with the guide way 10 of splayed, guide way 10 is arranged respectively in to first guide arm 5 and second guide arm 6, swing the in-process around handle formula push-and-pull rod 9, drive first guide arm 5 and second guide arm 6 follow-up operation, utilize and cut fork mechanism principle, realize that it adds the fork 3 to cut the fork, cut fork down and add the opening and shutting clamping function of tight pole 4, it has cable 8 to cut fork 3 afterbody connection on, realize quick electrically conductive butt joint. In this embodiment, the design of the guide groove 10 is such that when the handle-type push-pull rod 9 is pushed forward, the heads of the upper scissors fork tightening rod 3 and the lower scissors fork tightening rod 4 are clamped, and when the handle-type push-pull rod 9 swings backward, the heads of the upper scissors fork tightening rod 3 and the lower scissors fork tightening rod 4 are opened.

The upper scissor clamping rod 3, the lower scissor clamping rod 4, the first guide rod 5 and the second guide rod 6 are all made of pure copper, the insulating shell 1 and the handle type push-pull rod 9 are made of nylon 1010, and the rest are steel structural members.
