Explosion-proof plugging device with rapid installation function

Abstract

The invention relates to an explosion-proof plugging device with a rapid installation function. The plugging device comprises an explosion-proof isolation box and a plug terminal. A mounting cavity and a switch device positioned in the mounting cavity are arranged in the explosion-proof isolation box; side wing blocks with trapezoidal sections are respectively arranged on two sides of the switch device; the mounting cavity is provided with a mounting substrate below the switch device; the mounting substrate is provided with assembling mechanisms corresponding to the side wing blocks respectively, the assembling mechanisms form a transverse limiting structure, a longitudinal positioning structure and a vertical positioning structure in a clamping mode through a shape adapting part and a height adapting part, and the switch device achieves assembling of the handle support in a positioning combined magnetic attraction mode. By adopting the scheme, the explosion-proof plugging device withthe rapid installation function has the advantages that bolts are prevented from being used for mounting a switch device, the mounting convenience is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of an explosion-proof switch, in particular to an explosion-proof plug-in device with a quick installation function. Background technique [0002] The explosion-proof plug-in device includes an explosion-proof isolation box and a plug-in terminal. There is a switch device in the explosion-proof isolation box. electrical connection to the switchgear. Since the switchgear is set in the explosion-proof isolation box, the switchgear is isolated from the external environment, and the arc and spark generated by the switchgear when opening and closing are prevented from igniting the combustible substances in the external environment, which plays an explosion-proof role. In order to further improve the safety of the explosion-proof plug-in device, the explosion-proof isolation box is often equipped with an interlock mechanism, which restricts the plug-in terminal to the socket part when the switch device is in the ...

AI Technical Summary

Problems solved by technology

The above-mentioned installation methods have certain disadvantages. First, bolts are used to realize the connection between the components. If the switch device is frequently disassembled and assembled, it is prone to slipping, which will lead to the need to replace the explosion-proof isolation box. Moreover, in order to improve Due to the compactness of the explosion-proof plug-in device, the space between the side wall of the explosion-proof isolation box and the switchgear is often limited, which greatly increases the difficulty of operation for the staff who hold the screwdriver, and it is inconvenient to install when there is no electric screwdriver on site.
