Problems solved by technology

Screw connection is used, the sealing effect is poor, and rainwater is easy to enter the casing, making the controller easy to burn out and the car supercharger not working properly
The sealant connection can improve the sealing effect between the shell mouth and the shell cover, but because the material of the sealant is different from that of the shell, it is easy to degumming between the shell and the shell cover after a long time
Once the shell and the shell cover are unglued, rainwater will still enter the shell, which still cannot guarantee the normal operation of the car supercharger

Embodiment Construction

[0013] Such as figure 1 , 2 , 3, and 4, the controller shell of the present invention includes a box body 4 and a box cover 2, a circumferential groove is processed on the mouth end surface of the box body 4, and a heating wire running through its circumferential total length is placed in the circumferential groove 3. The edge of the lower side of the box cover 2 is processed with a circumferentially downward convex rib 1, the shape and size of which are suitable for the circumferential groove, and the circumferential downward convex rib 1 is embedded in the circumferential groove. In the groove, and make the lower side of the circumferential downward convex rib 1 contact with the heating wire 3. Both the box body 4 and the box cover 2 are made of plastic, and the box cover 2 and the box body 4 can be sealed and connected together by heating the heating wire 3 .

[0014] In order to facilitate the heating of the heating wire 3, the opposite sides of the circumferential groo...

Abstract

The invention discloses a controller shell. The controller shell comprises a box body; a box cover is arranged at the opening of the box body; the controller shell is characterized in that a circumferential groove is formed in the end plane of the opening of the box body; electric heating wires penetrating through the circumferential overall length of the circumferential groove are arranged in the circumferential groove; circumferential lower protruding ribs are arranged on the edge of the lower side face of the box cover; the shapes and the sizes of the circumferential lower protruding ribs are matched with that of the circumferential groove; the circumferential lower protruding ribs are embedded in the circumferential groove; the lower side faces of the circumferential lower protruding ribs are in contact with the electric heating wires; the box body and the box cover are both plastic products; and the box cover and the box opening can be connected together in a sealing manner by heating the electric heating wires in a power-on manner. The controller shell is good in sealing effect; by adoption of the shell, rainwater can be prevented from entering the shell, so that an automobile supercharger can work normally; and in addition, the controller shell is particularly suitable for an electronic actuator on the automobile supercharger.

Description

technical field [0001] The invention relates to an electric appliance casing. Specifically, it is a sealed housing used to accommodate circuit boards, especially for electronic actuators on automotive superchargers. Background technique [0002] It is well known in the automobile supercharger manufacturing industry that after the electronic actuator and its controller on the automobile supercharger are installed on the car, they are in a bare state and the working environment is poor. Therefore, the sealing quality of the controller shell is not only It determines whether the car supercharger can work normally, and also determines the service life of the controller. If the casing of the controller is not well sealed, once it enters the rainwater, it will be burned out, making the car supercharger unable to work. At present, the controller housing matched with the electronic actuator on the automobile supercharger is a traditional product. This controller housing includes a...
