Electrical Junction Box with Improved Shell Structure

Abstract

The invention relates to a junction box and discloses an electrical junction box with an improved housing structure. The electrical junction box is composed of a box body (1) and a box cover (2). Grooves (101) with wide upper parts and narrow lower parts are formed in the upper end surface of the box body (1); each groove (101) has a longitudinal section like a right-angle trapezoid; the lateral surface approaching the center of the box body (1) of each groove is a right-angle surface; and the lateral surface away from the center of the box body (1) is an oblique surface. Convex strips (201) in an interference fit relationship with the grooves (101) of the box body (101) are arranged at the lower end surface of the box cover (2). Water receiving slots (103) are arranged at the front end surface of the box body (1). A plurality of water through holes (104) that are arranged evenly and are communicated with the water receiving slots (103) are formed in the bottom of the grooves (101), wherein the water receiving slots (103) have bottom surfaces being oblique surfaces with higher inner sides and lower outer sides. According to the invention, on the basis of designs of the box body andthe box cover, a phenomenon that rainwater enters the box body through a connection slot between the box body and the box cover is avoided, so that the junction box has the high-efficiency waterproofperformance.

Description

technical field [0001] The invention relates to a junction box, in particular to an electrical junction box. Background technique [0002] In home decoration, the junction box is one of the electrical accessories, because the wires used for decoration pass through the wire tube, and the line at the joint of the wire is relatively long, or when the wire tube needs to be turned, the junction box is used as a transition. The pipe is connected to the junction box, and the wires in the wire pipe are connected in the junction box to protect the wires and connect the wires. [0003] During the use of the junction box, the terminal is generally fixed inside the box body by screws first, and then the box cover is fixed by screws, and the box cover and the box body are fastened by screws. Since the inside of the box is a terminal, it is necessary to ensure The waterproof performance of the box body, but the gap between the existing box body and the box cover can still seep into water...
