Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Example one

As shown in fig. 1-3, a special insulating cap of electric secondary terminal, including terminal main part 1 and insulating cap 2, the surface of terminal main part 1 is pegged graft with insulating cap 2, the inner wall of insulating cap 2 rotates and is connected with knob 3, the top inner wall fixed mounting of insulating cap 2 has fixed block 4, the inner wall of fixed block 4 rotates and connects cylinder 5, the equal fixed mounting in both ends has cylinder 5 about cylinder 5, the equal fixed mounting in both ends has threaded rod 6 about cylinder 5, the screw thread opposite direction of the threaded rod 6 of the 5 left and right sides of cylinder.

One end and the knob 3 fixed connection of cylinder 5 are kept away from to threaded rod 6, and the surface and the 2 rotations of insulator cap of threaded rod 6 are connected, and the surperficial threaded connection of threaded rod 6 has thread bush 7, and the bottom fixed mounting of thread bush 7 has movable plate 8, and the fixed surface of movable plate 8 installs buffer spring 9, and buffer spring 9 keeps away from the one end fixed mounting of movable plate 8 has splint 10, and the equal fixed mounting in upper and lower both sides that clamp plate 10 just is located buffer spring 9 on the surface has telescopic link 11.

In this embodiment, the user covers insulator cap 2 on terminal body 1, twist knob 3 afterwards, knob 3 clockwise rotation makes threaded rod 6 synchronous revolution, because the screw thread direction of the threaded rod 6 of the 5 left and right sides of cylinder is opposite, so two threaded rods 6 move in opposite directions, threaded rod 6 utilizes thread bush 7 to drive movable plate 8 to move, movable plate 8 utilizes buffer spring 9 to promote splint 10, splint 10 presss from both sides to terminal body 1 fixedly, along with thread bush 7 removes, movable plate 8 continues to move to terminal body 1 direction, so that buffer spring 9 is extruded jointly by movable plate 8 and splint 10 and is out of shape, buffer spring 9 plays the buffering and utilizes the elasticity to clamp, self-adaptation terminal body 1 model, so as to fix.

Example two

As shown in fig. 3-4, a compression spring 12 is sleeved on the surface of the telescopic rod 11, an arc edge plate 13 is fixedly mounted at one end, away from the clamping plate 10, of the telescopic rod 11, a supporting cylinder 14 is fixedly mounted on one side, away from the clamping plate 10, of the surface of the moving plate 8, a rubber ring 15 is fixedly mounted on the inner wall of the supporting cylinder 14, the surface of the rubber ring 15 is abutted to the arc edge plate 13, a connecting rod 16 is fixedly mounted on one side, away from the supporting cylinder 14, of the arc edge plate 13, and a lantern ring 18 is fixedly mounted on one side, away from the arc edge plate 13, of the connecting rod 16.

One side that movable plate 8 was kept away from to splint 10 and terminal main part 1 butt, movable plate 8 is L shape, telescopic link 11 comprises sleeve and carriage release lever, compression spring 12 cup joints on the carriage release lever surface, compression spring 12's one end fixed mounting is on the sleeve surface, compression spring 12's the other end fixed mounting is on the surface of circular arc sideboard 13, lantern ring 18 cup joints on the surface of knob 3, lantern ring 18 covers half of knob 3, the surperficial sliding connection of insulator cap 2 has stretch out board 17, lantern ring 18 spills on the surface of insulator cap 2.

In this embodiment, as the buffer spring 9 is compressed, the clamp plate 10 moves toward the moving plate 8, the clamp plate 10 pushes the compression spring 12 by using the telescopic rod 11, the telescopic rod 11 can not only extrude the compression spring 12, but also can control the compression direction of the compression spring 12 to prevent the compression spring 12 from bending, but because the rubber ring 15 blocks the arc edge plate 13, the compression spring 12 is compressed by the telescopic rod 11 and the arc edge plate 13 together, when the compressed elastic force of the compression spring 12 is greater than the resistance of the rubber ring 15 to the arc edge plate 13, the elastic force of the compression spring 12 can immediately pop the arc edge plate out 13, the arc edge plate 13 utilizes the connecting rod 16 to push the extension plate 17, the extension plate 17 enables the lantern ring 18 to cover the tail end of the knob 3, so that the user cannot continuously screw the knob 3, and avoid that the clamp plate 10 has too large extrusion force to the terminal body 1 due to continuously screw the knob 3, and the terminal body 1 is damaged and cannot be plugged.
