Connector

Abstract

The invention relates to a connector of an explosion-proof switch body, which is composed of a fixed plug, a movable plug and a socket, the socket is composed of a socket shell, touch boards and springs, each touch board shows the stepped groove shape, the two touch boards are back-to-back combined into two jacks, the movable plug and the fixed plug are respectively inserted into the two jacks, each spring between the two touch boards and the socket shell extrudes the touch boards for location, the socket is a bidirectional floating socket, the touch boards in the socket are floating touch boards, and the touch boards can automatically adjust the inserting angle with the plugs.

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 ...

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 the plug is difficult to insert or the contact quality is poor, which will bring trouble to the maintenance work. Difficult to come, not conducive to safe production
