Heat dissipation anti-loosening cable joint

Abstract

The invention provides a heat-dissipation anti-loosening cable joint, belongs to the technical field of cable joints, and aims to solve the technical problems that the joint of an existing cable joint is insufficient in strength, is easy to loosen and easy to heat. The heat-dissipation anti-loosening cable joint comprises a heat dissipation connector and an insertion connector, the heat dissipation connector is provided with a male head, a miniature diaphragm pump, a heat dissipation protection cover and a miniature fan, and heat dissipation fins are fixed to the outer side of the male head; a capillary heat dissipation pipeline is arranged between the heat dissipation connector and the heat dissipation protection cover, and the insertion connector is provided with a female head, a threaded ring, a pressing sleeve, a spring plate and a spring. Conical sleeves are arranged in the heat dissipation connector and the insertion connector, cables and fixed circular truncated cones are fixed to the male connector and the female connector, and guide locking sleeves are arranged on the fixed circular truncated cones. According to the invention, heat can be quickly dissipated through the cooling fins and circularly flowing cooling liquid, and serious heating is prevented; the female head is clamped in the male head, the spring plate tightly abuts against the pressing sleeve, and a positioning boss is clamped at the end part of a guide positioning groove, so that the connection is stable, loosening is prevented, and the connection strength is improved.

Description

[0001] The present invention belongs to application date: 2020-05-08, application number: 202010382545.9, patent name: a divisional application for a heat dissipation and anti-loosening cable joint. technical field [0002] The invention belongs to the technical field of cable joints, in particular to a heat dissipation and anti-loosening cable joint. Background technique [0003] Cable is a general term for optical cables, cables and other items. It is mainly used for power transmission and control such as control installation, connection equipment, and power transmission. It is an indispensable power device in daily life and industry. Continuous, each segment line must be connected as a whole, and cable joints must be used for these joints. Existing cable joints are often connected by threads, and loose threads will easily lead to loosening of the joints. Due to contamination and other reasons, it is easy to cause serious internal heating and cause safety accidents. [00...
