High-current socket switch

Abstract

The invention provides a high-current socket switch. The high-current socket switch comprises an insulating plate (7) and further comprises a solenoid valve (1) arranged on the insulating plate (7), a cylinder (2), a sliding block (3), a fixed block (4), a sliding guiding mechanism and a returning mechanism, wherein the solenoid valve (1) is connected with the cylinder (2), a piston push rod (21) of the cylinder (2) is connected with the sliding block (3), the fixed block (4) and the sliding block (3) are arranged on the sliding guiding mechanism, and the returning mechanism is connected with the sliding block (3). The high-current socket switch is convenient to close and open, damage of a socket caused by heating under the conditions of long-time work is avoided particularly, extremely large potential safety hazard is avoided, and accordingly the requirements of a production industry under high-temperature environments can be met.

Description

technical field [0001] The present invention relates to a socket switch, in particular to a large current socket switch. Background technique [0002] Traditional high-current sockets use metal clips to contact the plug for power supply. If the contact between the plug and the socket is not good, it is easy to generate heat between the plug and the socket, resulting in high temperature. The elasticity of the metal clip decreases, which causes the clamping force provided by the clip to decrease, and the reduction of the clamping force provided by the clip further leads to an increase in the contact resistance between the plug and the metal clip, which makes the socket heat up, and eventually causes the socket to damage. Therefore, the technical solutions in the prior art have certain limitations on the current, and cannot provide a large current. Especially in the case of long-term work, the socket will be damaged due to heat, which brings a great potential safety hazard, an...
