Fully-sealed junction box of motor

Abstract

The invention discloses a fully-sealed junction box for a motor; the junction box comprises a junction box cover, a first sealing gasket, a junction box body, a terminal base, a second sealing gasket and a motor shell, the junction box body is in a hollow shape with two open ends, and the junction box cover and the terminal base are connected to the two open ends of the junction box body in a covering mode to form a closed space for containing a motor. The first sealing gasket is clamped between the junction box cover and the junction box, the second sealing gasket is clamped between the junction box and the motor shell or between the terminal seat and the motor shell, an annular boss matched with the first sealing gasket is arranged on the surface, abutting against the first sealing gasket, of the junction box, and the first sealing gasket is in a hollow annular shape and is arranged on the annular boss in a sleeving mode. The terminal base comprises a flat-plate-shaped substrate and a conductive terminal embedded in and penetrating through the substrate, the conductive terminal is vertically conducted, the lower end of the conductive terminal is connected with the motor, and the upper end of the conductive terminal is connected with an external power source. The fully-sealed junction box has the advantages of being convenient to process, simple and reliable in structure, double in protection, capable of enabling the interior of the motor coil to be completely sealed, and capable of greatly reducing the risk that motor products used outdoors are affected with damp and turn-to-turn burn-in.

Description

technical field [0001] The invention relates to the technical field of motor junction boxes, in particular to a fully sealed junction box for motors. Background technique [0002] The motor is an energy conversion mechanism that converts electrical energy into kinetic energy. It uses the law of electromagnetic induction to convert the electrical energy of the grid into rotating mechanical energy. The motor needs a junction box for the introduction of electric energy. [0003] The motor junction box is used to introduce the electric energy of the industrial power supply into the motor, which is convenient for the motor to convert the electric energy into mechanical energy. However, the sealing effect of the motor lead wire connection in the junction box is not very good due to the gap opened by the lead wire connection. For outdoor use As far as the motor is concerned, it is very easy to cause the winding to be damp between turns due to poor sealing and water ingress inside ...

However, the sealing effect of the motor lead wire connection in the junction box is not very good due to the gap opened by the lead wire connection. For outdoor use As far as the motor is concerned, it is very easy to cause the winding to be damp between turns due to poor sealing and water ingress inside the motor, which will eventually lead to burn-out
