Grounding clamping piece for bellows signal cable

Abstract

A grounding clamping piece for a bellows signal cable includes a seal gasket, an inside hexagonal bolt and a hinge. An inside-contact piece is arranged in the middle of an inner cavity of a sealing element, and the outer ring of the sealing element is provided with the hinge. The inside-contact piece is a contact copper piece processed through high-temperature copper brazing on a pressing-connecting pipe, it is guaranteed that the included angle between the contact copper piece and the pressing-connecting pipe is 45 degrees through a clamp, and the shape of ripples in the outer ring of the pressing-connecting pipe and the shape of the bellows signal cable are consistent in size; inner corrugated grooves are formed in the two ends of the inner cavity of the sealing element, the middle portion of the inner cavity and the pressing-connecting pipe in the inside-contact piece are consistent in shape and structure, and a cable is inserted in an inner cavity of a grounding wire outlet tail pipe on the sealing element. According to the grounding clamping piece for the bellows signal cable, the defects that an original grounding clamp of a mobile base station main signal cable and an original grounding clamp of a microwave communication signal cable are large in contact resistance, unreliable in long-term work, poor in waterproof performance, large in mounting randomness and incapable of being used repeatedly are overcome.

Description

Technical field: [0001] The invention relates to lightning protection and electromagnetic interference protection for main signal cables of mobile communication base stations and microwave communication signal cables [0002] The field of grounding, especially the corrugated pipe signal cable grounding clips in this field. Background technique: [0003] In order to protect the main equipment of the mobile communication base station and the main equipment of microwave communication, and reduce the risk of breakdown of the main equipment by the electromagnetic interference of the signal transceiver system and the strong current generated by lightning, the main signal cable of the mobile base station and the microwave communication signal cable must be used before entering the equipment room equipment. Three-point grounding, and its grounding clip will provide grounding protection for the signal cable. At present, the grounding cards in the above-mentioned equipment mainly ...

AI Technical Summary

Problems solved by technology

It solves the defects of large contact resistance of the original grounding card of the main signal cable of the mobile base station and the microwave communication signal cable, low long-term working reliability, poor waterproof performance, large installation randomness, and the defects that cannot be reused for many times. The invention can not only ensure the internal contact There is a small contact resistance between the components and the signal cable, and it can meet the long-term outdoor waterproof performance and instantaneous high-current impact, and reduces the cost
