Wire joint protection device for circuit area network

Abstract

The invention provides a wire joint protection device for a circuit area network. The wire joint protection device comprises a main body, a screw cap, a waterproof ring and a pressing screw cap; the main body comprises a rotating table located in the middle and threaded connecting pieces arranged on the two sides of the rotating table, when two electric wires need to be installed in the device, the first rotating disc is rotated, first wire bunching holes in the first rotating disc and the second rotating disc are made to coincide, second wire bunching holes in the first rotating disc and the second rotating disc are made to be staggered, and then the sealing locking piece only provides two wire bunching holes; the two electric wires penetrate through the main body and the two bunching holes I respectively and then are sleeved with the waterproof rings, and the threaded connecting pieces at the two ends of the main body are in threaded connection with the nuts and the pressing nuts respectively, so that the two electric wires are sealed and fixed in the device; and when three electric wires need to be installed in the device, the first rotating disc is rotated, the first wire bunching hole in the first rotating disc and the second wire bunching hole in the second rotating disc are made to coincide, the sealing locking piece can provide three wire bunching holes, the operation is repeated, and the three electric wires are fixed in the device in a sealed mode.

Description

technical field [0001] The invention relates to the field of wire joint protection devices, in particular to a wire joint protection device for a circuit area network. Background technique [0002] Wire joints are also called wire heads. After the wire is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The protective wire joint is a layer of fastening combination fixed on the outside of the wire joint by a locking structure. Parts; wire connector is a kind of connecting device often used in power system. In many electrical equipment and cable connection parts, cable connectors are used as cable fixing and protection parts, and at the same time achieve the purpose of waterproof, moisture-proof and shielding, so as to ensure the safety of the equipment. Safe to use. [0003] When laying wires in the circuit area network, most of the laid cables are installed with 2-3 wires. T...

Problems solved by technology

[0003] When laying wires in the circuit area network, most of the laid cables are installed with 2-3 wires. Therefore, corresponding two-hole or three-hole wire fixing devices will be installed in the wire connectors to bundle them. November 26, 2019 The Chinese invention patent with the announcement number of CN209692329U disclosed in Japan, discloses a porous cable joint. The device fixes the wires in the wire joint through a sealing lock. The wire hole can realize the wiring harness of different numbers of wires. However, if only 2-3 wires need to be bundled, the redundant wire harness holes on the sealing and locking parts will make the sealing effect of the device on the wires poor, and the use effect is not ideal.
