Composite socket

Abstract

The invention discloses a novel multi-cable socket, and relates to a connecting device of an electric system. The novel multi-cable socket is used for solving the problems that after multiple times of inserting and pulling are carried out, the impedance of contact faces between reeds can be increased to a certain degree, the voltage drop is increased, and accordingly the reeds are heated; the reeds are prone to generating deformation after a long time, and the service life is short are solved. The novel multi-cable socket comprises shunt socket bodies. Each shunt socket body comprises the front wiring end, the rear wiring end, a front copper column, a rear copper column, an insertion opening and a base plate, the insertion opening comprises a front double-reed sheet and a rear double-reed sheet, the front double-reed sheet comprises an upper single-reed sheet and a lower single-reed sheet which are separated, the rear double-reed sheet comprises an upper single-reed sheet and a lower single-reed sheet which are separated, the opposite faces of the front ends of the upper single-reed sheets of the front double-reed sheet and the rear double-reed sheet are bent to form upper contact faces, the upper single-reed sheets of the front double-reed sheet and the rear double-reed sheet are connected through the upper contact faces, the opposite faces of the front ends of the lower single-reed sheets of the front double-reed sheet and the rear double-reed sheet are bent to form lower contact faces, and the lower single-reed sheets of the front double-reed sheet and the rear double-reed sheet are connected through the lower contact faces; limiting protrusions are arranged at the opposite ends of the front copper column and the rear copper column respectively; due to the fact that the shunt socket bodies are improved, the multi-cable socket is reliable.

Description

technical field [0001] The invention relates to a wiring device for a power system, more specifically, a composite socket for an electrical secondary circuit. . Background technique [0002] In the power system, the electric energy meter (electric energy meter) connected to the secondary circuit is connected to the secondary metering circuit of the substation by a joint terminal junction box to transmit voltage and current signals. The connection method is screw and metal slide connection, as The circuit meters of legal metering instruments must be regularly checked annually. The current method is to use a composite intelligent terminal junction box. [0003] Patent document 201220711690.8 (application date: 2012.12.21) discloses a composite intelligent terminal junction box, including a front terminal, a rear terminal and a composite socket. The terminal is connected to the lower reed of the composite socket through a wire. The composite socket is composed of 10 shunt soc...

Problems solved by technology

[0004] However, it has the following disadvantages. The contact surface between the reeds of the composite socket in the intelligent junction box is small, and the contact surface between the reeds is similar to a line contact. After repeated plugging and unplugging, the impedance of the contact surface will increase. Increase the pressure drop, causing the reed to heat up; the reed is prone to deformation after a long time, and the service life is short; the reed and the copper column are mainly connected by welding, and the pressure drop is large
