0.4kV low-voltage cable intermediate joint connecting device

Abstract

The invention discloses a 0.4kV low-voltage cable intermediate joint connecting device, which is used for solving the problems that the cable connection and fixation effect is poor and that the time consumed by butting the cable is long in the prior art. The device is characterized in that one end of a male joint is a plug, and the other end is a wiring part; one end of a female joint is an inserting groove, and the other end is a wiring part; the plug is cylindrical, the side surface of the plug is fixedly connected with a clamping head, and the clamping head is a cuboid and inclines towardsthe wiring part of the male joint; the shape of the inserting groove is matched with that of the plug, the inserting groove is a cylindrical groove, the inner wall of the cylindrical groove is radially provided with a semicircular groove, the semicircular groove can accommodate the clamping head to pass through, the inner wall of the cylindrical groove is provided with a guide groove in the circumferential direction, the guide groove is an eccentric groove, the depth of the guide groove becomes shallow gradually, and the clamping head is screwed into the guide groove until being clamped; and the wiring part is a hollow circular hole, and the outer side of the wiring part is provided with a wire pressing threaded hole communicated with the hollow circular hole. The beneficial effects are that the time consumed by butting the cable is short, the power supply reliability is improved, the failure power outage time of users is reduced, and the working efficiency of the staff is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a 0.4kV low-voltage cable intermediate joint connection device. Background technique [0002] 0.4kV low-voltage cables refer to power cables with a rated voltage of 0.4kV, which are used to directly transmit electric energy to low-voltage electrical equipment and are an important part of low-voltage power distribution systems. Low-voltage cables are composed of three parts: core, insulation layer and protective layer. The wire core is used to conduct current and is generally made of twisted copper wires or aluminum wires. [0003] With the society's increasing dependence on electricity, power outages not only have a great impact on the daily life of residents, but also threaten the safety of people's lives and property, affecting the safe and stable operation of society. In order to solve the various inconveniences caused by power failures to power users, emergency powe...
