Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Example 1

Referring to fig. 1-2, the anti-drop terminal base for the binding screw comprises a screw 1 with a gasket 2, an elastic sheet 3, a nut 4 and a base 6, wherein a through hole for the screw 1 to pass through is formed in the middle of the elastic sheet 3, the gasket 2 penetrates between the screw 1 and the elastic sheet 3, and the gasket 2 is used for blocking a screw head of the screw 1 and preventing the screw head of the screw 1 from being screwed into the through hole in the middle of the elastic sheet 3; the terminal structure of the screw 1 is mechanically damaged by using equipment, the thread of the screw rod at the terminal of the screw 1 is damaged to form a damaged terminal 5 of the screw, and the thread cannot be screwed down through the nut 4; at this time, the undamaged threaded rod of the screw 1 can still be screwed up, but the screw 1 cannot be detached from the nut 4, thereby effectively preventing the screw 1 from falling off.

The shell fragment 3 is installed on base 6, shell fragment 3 both sides are equipped with the eye-splice, are equipped with the nut draw-in groove that is used for nut 4 to place on the base 6, and nut draw-in groove both sides are equipped with and are used for eye-splice male slot, in order to avoid shell fragment 3 to insert and drop behind the slot, preferably, the side of eye-splice is the cockscomb structure, carries out the interlock with base 6 behind the eye-splice inserted slot to realize being connected of shell fragment 3 and base 6.

Example 2

The binding post base that binding screw anti-drop described in embodiment 1, including screw 1, shell fragment 3, nut 4 and the base 6 of taking gasket 2, screw 1, shell fragment 3 and nut 4 of taking gasket 2 assemble into the wiring subassembly, shell fragment 3 installs on base 6.

In order to facilitate the screwing or unscrewing operation of the screw 1, a cross-shaped groove is formed in the head of the screw 1, and a straight-shaped groove can be formed to facilitate the screwing operation of a screwdriver; the screw head of the screw 1 is a round head, and can also be a hexagon screw head, and the screw 1 can also be screwed by adopting a hexagon wrench.
