Motor junction box

Abstract

The invention discloses a motor junction box comprising an upper cover and a box body fixed to a wire holder, wherein a fixing groove for mounting the box body is formed in the wire holder, an inward groove is formed in the outer side of a lower end of the box body, a sealing ring is arranged on the side edge of the fixing groove, the sealing ring is jointed with the groove, a cloud motherboard is fixed to the bottom of the box body, two fixing blocks are arranged on the bottom of the box body on left and right sides of the cloud motherboard, a sealing plate is inserted between two fixing blocks, a fixing seat for fixing a wiring board is arranged at the bottom of the box body on front and back sides of the cloud motherboard, a mounting plate fixed to the fixing seat is arranged on the lower end of the wiring board, a plurality of binding posts are arranged on the wiring board, a supporting plate located at the same height as the upper end of the sealing plate is arranged on inner walls of the front and back sides of the box body, an upper sealing plate is fixed to the supporting plate and the sealing plate, and an upper cover is fixed to the box body on the upper end of the upper sealing plate. The motor junction box is simple in structure, reasonable in design, is able to enhance the sealing and prevent external dust from entering the junction box to damage the interior to cause explosion.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor junction box. Background technique [0002] The motor junction box is to introduce the wires in the motor into the junction box and connect them with the wires introduced from the outside. The junction box must prevent dust and other media from entering, and at the same time, it is necessary to prevent the inside of the junction box from rusting. Some junction boxes may explode due to poor sealing. However, it is difficult to ensure complete sealing of the junction box in the prior art. Contents of the invention [0003] In order to solve the above problems, the present invention provides a junction box with good sealing performance, which can prevent the gas inside the motor and the medium outside the junction box from entering. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] The invention rela...
