Abstract

This utility model discloses a mine-use explosion-proof terminal block, relating to the field of explosion-proof electrical equipment technology. This utility model, by setting up a distribution plate, a limiting plate, a conductive rod, and a limiting block, categorizes and passes wires through the distribution plate and distribution groove, and limits their movement under the action of the limiting plate. During installation, the wires are connected to the conductive rod, and then the terminal plug is simply inserted into the corresponding connector to complete the installation. This facilitates the simultaneous connection of multiple wires and is convenient to operate. Furthermore, when the cover is closed, the limiting block on the bottom surface of the cover abuts against the limiting plate, thereby improving the stability of the limiting plate in limiting the wires and preventing wire detachment. By setting up a sliding groove, a placement box, and a mating block, the placement box contains a desiccant that absorbs water mist, ensuring the inside of the terminal box is dry and guaranteeing normal equipment operation. Simultaneously, the placement box can be pulled out of the sliding groove by a pull plate, facilitating the replacement of the desiccant and further extending the service life of the terminal box.
