Embodiment Construction

[0035] Such as figure 1 As shown, a plug assembly for a main circuit connector, the fixing bracket 1 is molded from a metal material, used as a plug positioning frame, and has sufficient mechanical strength. The conductive strip 2 of the plug is single-piece or laminated. Two ends of the outer surface of the conductive strip 2 of the plug have two shoulders 7 , and the spring piece 3 is arranged between the two shoulders 7 . The left and right symmetrical paired plug conductive strips 2 and spring strips 3 are inserted into the fixed bracket 1. The spring strip 3 is a straight spring strip. There is a semicircular gap on one side of the middle end of the plug conductive strip 2. When the piece 2 enters the 1 fixing frame, there are two semicircular gaps at the middle end of the double-sided plug piece, forming a full circle, and the opening expansion tube cylindrical pin is inserted into the center of the fixing bracket 1 and passes through the full circle of the left and righ...

Abstract

The invention relates to the technical field of draw-out switch equipment, in particular to a plug unit for a main circuit connector, which comprises a fixed bracket, paired plug conducting strips, spring pieces and cylindrical pins; the paired plug conducting strips are inserted in the fixed bracket; the socket ends of the paired plug conducting strips are separated into socket openings; the cylindrical pins are fixed to the fixed bracket and are located between the paired plug conducting strips; the plug conducting strips are provided with arc grooves matched with the cylindrical pins, and the plug conducting strips arranged at the left and right sides take the cylindrical pins as deflection centers; the spring pieces are disposed among the outer side surfaces of the plug conducting strips and the fixed bracket; and a compact force is formed between the paired plug conducting strips. The plug unit for the main circuit connector has the advantages that: friction force of the connector opened by expansion is reduced by cooperation of the cylindrical pins and the plug conducting strips, so that the plug unit has high reliability and large contact pressure.

Description

technical field [0001] The invention relates to the technical field of withdrawable switchgear, in particular to a plug assembly for a main circuit connector. Background technique [0002] The main circuit connector is an electrical accessory for the main circuit power feed-in and out-feed of the drawer unit in the withdrawable switchgear. The feed-in and out-feed of the main circuit power of the drawer unit is realized by connecting the two sets of main circuit plugs in and out with the bus bar and the outlet socket, the incoming line is connected with the upper end of the switch, and the outgoing line is connected with the lower end of the switch. [0003] Withdrawable switchgear from the mid-1980s, the domestic industry introduced technology from abroad. After 1994, the domestic industry has self-developed cabinet technology. The structural principle, manufacturing process and performance indicators of the main circuit connector must comply with GB7251.1, JB / T9661, JB / T...
