Cable plugging type connector for transformer

Abstract

Disclosed is a cable plugging type connector for a transformer. The cable plugging type connector comprises a main connector and a sub connector; the main connector comprises an insulating sleeve and a plurality of arc-shaped fixed plates; annular springs are arranged on both of the upper part and the lower part of the arc-shaped fixed plates in a surrounding manner so as to form a hollow cavity, used for allowing the sub connector to be inserted, among the arc-shaped fixed plates in a surrounding manner; elastic rubber sleeves are arranged between the arc-shaped fixed plates and the side wall of the insulating sleeve; the sub connector comprises an insulating leather sleeve and a conductive rod, wherein one end of the conductive rod is inserted into the insulating leather sleeve; and one end, positioned in the insulating leather sleeve, of the conductive rod is connected with a cable core, while a conductive head which extends into the hollow cavity to be in contact with an arc-shaped concave part is arranged at the other end. According to the main connector, the multiple arc-shaped fixed plates are matched with the annular springs to form the hollow cavity used for allowing the sub connector to be inserted; and after the sub connector is inserted into the hollow cavity by overcoming the elasticity of the annular springs, the sub connector can be tightly clamped by the arc-shaped fixed plates under the elasticity of the annular springs, so as to improve connection firmness.

Description

technical field [0001] The invention relates to a cable connector used in the electrical field, in particular to a cable plug-in connector for a transformer. Background technique [0002] With the continuous development of urban construction, cable power supply has become the mainstream of the city, the demand for high-voltage cross-linked cable accessories is increasing, and the types of products are also increasing. Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each segment line must be connected as a whole. These connection points are called cable joints. The cable joints in the middle of the cable line are called intermediate joints, and the cable joints at both ends of the line are called terminal heads. The cable joint is used to lock and fix the incoming and outgoing lines, and play the role of waterproof, dustproof and shockproof. The existing high-voltage power cable joints mainly include straight-through...

AI Technical Summary

Problems solved by technology

Regardless of whether it is a rubber prefabricated joint, a silicone rubber cold-shrink joint, or a pre-expanded joint, their installation method is to put the main body of the joint on the cable first, and then crimp the connection fittings, so the cable processing length is longer, and the joint The main body itself does not have waterproof performance, and the waterproof and moisture-proof problem must be solved by means of a glue-filled protective case, which is extremely inconvenient to install
