Connection device with grounding connector for electrical distribution box

Abstract

The invention discloses a connection device with a grounding connector for an electrical distribution box. The connection device comprises a connection terminal, wherein an electrical appliance connector capable of being connected with an electrical appliance terminal in the electrical distribution box is arranged at one end of the connection terminal; a lead wire connector capable of being connected with a cable is arranged at the other end of the connection terminal; a cylindrical grounding connector is also vertically arranged in the middle of the connection terminal; a grounding connector insulating housing is also arranged outside the grounding connector; one end of the connection terminal is connected with a cable terminal stud bare wire through the lead wire connector and the other end is connected with the electrical appliance terminal in the electrical distribution box through the electrical appliance connector when the connection terminal is used; and the grounding connector is connected with a grounding wire, so that connection between the cable and the grounding wire is achieved; the connection device is simple in structure, easy to process, simple and convenient to install and dismantle, good in safety and high in universality; and the grounding efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular to a wiring device with a grounding connector for an electric distribution box. Background technique [0002] In the process of overhauling and maintaining power equipment or cable lines, it is necessary to ensure that the power equipment or cable lines are reliably grounded to prevent the danger to the human body caused by the dangerous voltage generated by a sudden call or the induced voltage generated by adjacent lines. Therefore, it is a very important electrical safety measure to ground the electrical equipment or cable lines through the grounding wire. There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. At present, terminals are usually used to connect cables and electrical terminals in the electrical distribution box, but there is no grounding installed on this terminal. In addition, there is n...

Problems solved by technology

There are two types of existing low-voltage grounding wires: clip-type grounding wire and duckbill-type grounding wire. At present, terminals are usually used to connect cables and electrical terminals in the electrical distribution box, but there is no grounding installed on this terminal. In addition, there is no space reserved for the installation of grounding wires at the electrical terminals of the low-voltage distribution box, and there are many branches of the low-voltage outlets, the distance between adjacent low-voltage switches is small, and the space of the low-voltage equipment itself is relatively small, resulting in The above two kinds of grounding wires cannot be directly grounded in the low-voltage distribution box. In order to ensure emergency repairs, sometimes only the busbar can be grounded. Fault
