Power cable with connecting device

Abstract

The invention discloses a power cable with a connecting device, relating to the field of power cables. A connecting piece body is included, a mounting groove is formed in the connecting piece body, aconnecting cover is connected to the outer side of the mounting groove, an air bag is arranged in the inner side of the connecting cover, a pressing bag is arranged in the outer side of the connectingcover, an extrusion block is arranged at the top end of the interior of the mounting groove, an extrusion contact is connected to the top end of the extrusion block, and a threaded rod is connected to the bottom end of the extrusion block. The power cable is provided with the connecting piece body, the mounting groove, the connecting cover, the air bag, the pressing bag, the extrusion block, theextrusion contact, the threaded rod, a sleeve rod, a sliding block, a push rod, a first bevel gear, a second bevel gear and a grip, so that a cable connector is arranged between the mounting groove and the connecting cover, the connecting cover can apply pressure to the cable through the air bag to enable the cable to be fixed more stably, the mounting groove can jack the extrusion block and the extrusion contact upwards, pressure is applied to the cable from the lower portion, and cable connection is more stable through dual pressurization.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a power cable with a connecting device. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] The existing cable joints are connected by connecting parts such as hoops, but the hoop connection structure is simple and the connection method is single, and the cables at the joints cannot be double-clamped to fix them inside, and the existing cable conn...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing cable connectors cannot double-clamp the cables at the joints to fix them inside, and the existing cable connectors cannot be connected to each other, and a single set of cables cannot fixed, and the existing cable connectors cannot protect the connection, reduce the problem of damage near the connection, and provide a power cable with a connection device
