Dual-function bushing

Abstract

The invention discloses a dual-function bushing which is provided with a wire-protecting groove. The bushing is provided with a fixed surface which fits the plane of a through hole. The wire-protecting groove is arranged on the fixed surface. The depth matches the diameter of a cable to be protected. The length direction is parallel to the plane of the through hole. The outer side end of the wire-protecting groove is open, and the inner side end is closed. Fixing structures are arranged on both sides of the wire-protecting groove of the bushing to fix the bushing on the plane of the through hole. The fixed surface fits the plane of the through hole, and the position of the inner side end of the wire-protecting groove corresponds to the position of the through hole. A number of elastic ribsare arranged in the wire-protecting groove with cross spacing. The ribs are raised on the bottom and / or the side wall of the wire-protecting groove. The dual-function bushing provided by the invention has the advantages that through hole protection is provided for the cable; the cable can be bent and fixed; and the cable has the function of pull resistance.

Description

technical field [0001] The invention belongs to the field of electrical materials, in particular to a dual-function wire sheath. Background technique [0002] On electrical equipment, when a cable needs to pass through a perforation on a certain plane, a wire sheath needs to be installed at the perforation to protect the cable and prevent it from being worn through by the hole wall of the perforation. Common wire grommets at present, such as "a wire grommet" disclosed in Chinese patent document CN101924334A on December 22, 2010, include a body and a first flange and a second flange respectively arranged at both ends of the body. flange, an annular slot is formed between the first flange and the second flange along the circumference of the sleeve, and the wire grommet is also provided with a The plurality of slots on the inner surface of the second flange divide the first flange and the sleeve into a plurality of corresponding parts. In a preferred embodiment, the diameter ...

AI Technical Summary

Problems solved by technology

There are two problems caused by this: first, the whole perforated wiring work needs to be completed by two steps of perforation and bending, and the two steps respectively use the grommet and the cable card, the operation is complicated, and the two auxiliary materials are indispensable , neither in terms of operating efficiency nor in the cost of auxiliary materials; second, in this traditional perforated wiring structure, if the cable is accidentally pulled, the pulling force will be directly transmitted to the end of the cable, The force on the fixed point at the end is too large. If the end is a welding point, it may cause the welding to loosen, the circuit is interrupted, and the whole machine may not work properly.
