Description

Dampproofing relay protection wiring junction box Technical Field The utility model relates to the technical field of junction boxes, in particular to a moisture-proof relay protection junction box. Background The junction box is often used in a relay protection circuit to wire and conduct junction operation, the existing junction box is provided with a plurality of threading holes in a box body, connectors are arranged at the threading holes, clamping pieces are arranged on the connectors, nuts are arranged on the connectors in a threaded mode, the wires and the box body are fixed through the matching of the clamping pieces and the nuts, sealing and moisture prevention are achieved, but in the actual use process of the junction box, the situation that the wires are not installed in part of threading holes exists, the inside of the box body is communicated with the outside through the threading holes, sealing and moisture prevention cannot be achieved, short circuit situations can be caused, and potential safety hazards exist. Accordingly, there is a need for a moisture resistant relay protection junction box that solves the above-described problems. Disclosure of utility model The utility model provides a dampproof relay protection junction box, which realizes the sealing of a threading hole through the arrangement of a sealing plate, improves the dampproof performance of a box body, and realizes the sealing connection of an electric wire and the box body by matching with a connecting sleeve. The technical scheme of the utility model is realized as follows: The moistureproof relay protection junction box comprises a box body, the lid is installed at the box body top, fixed mounting has the connection terminal in the box body, be equipped with a plurality of through wires holes on the box body lateral wall, along horizontal slidable mounting on the inner wall of box body a plurality of pairs of closing plates that are used for sealing the through wires hole, every through wires hole department all is provided with a locking subassembly, still including the cover that overlaps to locate on the electric wire, adapter sleeve one end is equipped with and is used for will correspond two closing plate pushes away the top of pushing away to both sides leans on the inclined surface, be equipped with on the outer peripheral surface of adapter sleeve and be used for carrying out spacing annular groove with the closing plate after pushing away, sliding mounting has trapezoidal sliding tray in the annular groove, be equipped with on the outer peripheral surface of trapezoidal sliding tray and reset inclined surface, the top lean on inclined surface with reset inclined surface's incline opposite direction, the other end of adapter sleeve be provided with the rubber seal cover of electric wire outer peripheral surface looks adaptation. As a preferable technical scheme, each locking assembly comprises a locking sleeve fixedly installed in the corresponding threading hole, the free end of the locking sleeve extends to the outer side edge of the box body and is provided with a plurality of clamping pieces, and a locking nut is installed on the locking sleeve in a threaded mode.
