Abstract
Description
Technical field:
[0001] The invention relates to an electrical connection device for a mine explosion-proof switch body. Background technique:
[0002] At present, the electrical connectors of the explosion-proof switch body are all one-way fixed sockets, such as the mining explosion-proof combination switch developed by Changzhou Lianli Automation Technology Co., Ltd., the model is ZB-4×400 / 660 (380), its The main body connector is composed of a plug and a fixed socket. The fixed socket has only one-way socket. The contact plate is fixed with screws. The cooperation between the contact plate and the plug depends on its own elasticity, the clamping force is small, and the contact surface cannot be guaranteed. Therefore, when the rated current passes through, it often generates heat, which not only affects production, but also has a short service life; since the contact plate is fixed on the socket, the relative position to the plug is required to be very accurate, otherwise ...
