Cable terminal box with anti-jamming function

Abstract

The invention discloses a cable terminal box with an anti-jamming function. The cable terminal box comprises an upper shell and a lower shell which are connected through a connector, wherein at leastone upper semicircular hole and at least one lower semicircular hole which are opposite are formed in longitudinal side walls of the upper shell and the lower shell separately; a circular cable connection hole is formed by each upper semicircular hole and the corresponding lower semicircular hole; holes which are sequentially arranged are formed in transverse side walls of the upper shell and thelower shell separately; shading breathable pad layers are fixedly arranged in the corresponding holes in inner side walls of the upper shell and the lower shell; at least one intermediate cable jointis arranged in the cable terminal box; two ends of each intermediate joint are clamped into the corresponding cable connection holes separately; each intermediate joint comprises a hollow insulating cutting sleeve; each insulating cutting sleeve sleeves a metal mesh cover; and each metal mesh cover sleeves an insulating wire sleeve. The cable terminal box has the advantages that the joints are fastened and are not easy to loosen, and the cable terminal box has environmental temperature change resistance and high anti-jamming capability.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a cable junction box with an anti-interference function. Background technique [0002] The cable junction box is the most common and widely used connection device in the construction and communication fields, which can protect the joint parts. In addition to the general functional requirements of the existing finished junction boxes, different types of new cable junction boxes have gradually been developed, for example, waterproof and splash-proof junction boxes, thermocouple junction boxes, explosion-proof junction boxes, solar junction boxes, etc. Various styles of cable junction boxes meet the needs of junction boxes with different functions under different working conditions. However, the general cable joint box is made of engineering plastic ABS, and its thermal expansion coefficient is different from that of metal joint materials. Under different stresses or thermal ...

AI Technical Summary

Problems solved by technology

However, the general cable joint box is made of engineering plastic ABS, and its thermal expansion coefficient is different from that of metal joint materials. Under different stresses or thermal environments, the thermal shrinkage performance of various materials is also different, resulting in the junction box Different temperature differences inside and outside will cause uneven expansion or contraction, which may lead to problems such as uneven tightness of the cables in the junction box, which further leads to poor connection effects. At the same time, the cable junction box in the prior art has no anti-interference effect. ideal

[0003] Therefore, it is necessary to improve the cable junction box in the prior art so that it can overcome the problems of cable loosening and interference caused by large temperature changes
