Description

Technical Field

[0001] The utility model relates to the technical field of starter electromagnetic switches, in particular to a casing of an automobile starter electromagnetic switch. Background Art

[0002] The starter electromagnetic switch mainly includes a shell, a coil, a moving iron core, a static iron core, a moving contact, a contact piece and two contacts. A coil is arranged in the shell, one end of the moving contact is connected to the static iron core, and the other end is connected to the moving iron core. The contact piece is arranged on the moving contact. When the moving and static iron core coils of the electromagnetic coil are energized, the moving iron core moves forward, pushing the contact piece to connect with the two contacts.

[0003] After searching, the patent application with the number CN210110652U discloses a breathable and waterproof structure for an automobile starter electromagnetic switch, including a switch body and a switch cover, the switch body and the switch cover are assembled, the switch cover and the switch body form a space, a contact copper plate and two contact bolts are installed in the space, and a breathable hole is provided on the switch cover, which connects the space formed between the switch cover and the switch body to the outside world. In this way, water from the outside world cannot enter the contact position, ensuring that the contact will not freeze, thereby ensuring that the car can start normally in a cold environment.

[0004] However, due to the arrangement of the switch body and the switch cover, when the vehicle is driving, the vehicle vibrates continuously, the switch body vibrates strongly, and the shock absorption effect is poor, which easily affects the service life of the switch body. At the same time, when the switch body needs to be disassembled for maintenance, the switch body cannot be quickly disassembled due to the integrated structure of the shell, which is time-consuming and labor-intensive, and inconvenient to install and disassemble.

[0005] Therefore, we propose an automobile starter electromagnetic switch housing. Utility Model Content
