A heavy-duty connector for internal and external wiring of electrical panels

Abstract

The invention relates to the technical field of wiring connectors, and especially relates to a heavy-type connector capable of realizing wiring between an internal part and an external part of an electric shielding cabinet. The heavy-type connector comprises a plug and a socket. The plug is provided with a substrate. The substrate is fixed on a guide rail in an electric cabinet. The plug is internally provided with a male pin and a male end pin sleeve. The male end pin sleeve is provided with the pin. The rear end of the pin is connected with an electric wire. The rear end of the male end pin sleeve is connected with a shielding layer of a shielding wire. The socket is internally provided with a female plugging sleeve and a female end pin sleeve. The female end pin sleeve is provided with a female plugging sleeve. The rear end of the female plugging sleeve is connected with the electric wire. The rear end of the female end pin sleeve is connected with the shielding layer of the shielding wire. The plug and the socket are connected through a male plugging core frame and a female plugging core frame. According to the invention, the occupied space for the installation and the wiring of the heavy-type connector is small, the heavy-type connector male end pin sleeve and the female end pin sleeve (used for the shielding wire) are capable of improving the anti-interference capability of the shielding wire, the guide rail is utilized for installation, the connector is convenient to fix, and the dismounting is convenient.

Description

technical field [0001] The invention relates to the technical field of wiring connectors, in particular to a heavy-duty connector for realizing internal and external wiring of an electric screen cabinet. Background technique [0002] In the traditional electrical screen cabinet, the common control line uses terminals to realize the electrical connection with the external electrical equipment, and the sensor signal line directly enters the electrical cabinet and connects with the micro-computer cabinet in the electrical cabinet. [0003] In the new electric screen cabinet, the control line adopts a circular connector to realize the electrical connection with the external equipment, and the signal line of the sensor is connected to the micro-cabinet in the electric screen cabinet through the wire terminal. [0004] The existing electrical screen cabinets have the following problems: [0005] 1. Terminals are used for wiring. When the electrical cabinet is installed, all the w...

AI Technical Summary

Problems solved by technology

[0005] 1. Terminals are used for wiring. When the electrical cabinet is installed, all the wires are manually connected one by one; when the electrical cabinet is disassembled, all the wiring must be removed from the terminal. Disconnecting the wiring is very troublesome, the workload is heavy, and the wiring is wrong. higher rate;

[0006] 2. The circular connector is adopted. Since the wiring at both ends of the connector plug and socket has a bending radius requirement, the space occupied by the connector in the depth direction of the electrical cabinet is relatively large;

[0007] 3. The communication lines that directly enter the electrical cabinet need to be manually connected one by one on the vehicle; when the electrical cabinet is lifted from the locomotive, the communication lines on the micro-computer cabinet must be removed from the cabinet first, and then hoisted away from the electrical appliances cabinet

[0008] If terminal blocks are used to cut off the communication line, the disassembly of the communication line is relatively convenient, but the shielding layer of the broken communication line is also broken, the shielding effect of the communication line will be affected, and the communication line will be interfered by other nearby electrical equipment, which will affect the normal operation of the computer to the locomotive. control
