Technical Field

[0001] This utility model belongs to the field of electromagnetic valve technology, and in particular relates to an electromagnetic valve plug. Background Technology

[0002] Solenoid valve connectors are widely used in electronics, machinery, communications, aviation, marine and automotive fields. A solenoid valve connector includes a solenoid valve plug and a solenoid valve socket. The solenoid valve socket is fixedly connected to the solenoid valve coil, and the solenoid valve plug is fixedly connected to the power supply cable. The solenoid valve plug can be detachably plugged into the solenoid valve socket through a connector to connect the power supply.

[0003] Currently, commercially available solenoid valve plugs typically consist of a housing. This housing is formed by the joining of a front and rear shell, creating a hollow structure with an internal cavity. Several conductive prongs are installed inside the housing, electrically connected to an external power source via a power cable. The housing is fitted with mounting screws for detachably connecting the solenoid valve plug to the solenoid valve socket. However, such solenoid valve plugs usually require positioning blocks within the housing to fix and limit the conductive prongs, and may even require glue filling, leading to inconvenience in disassembling and maintaining the internal components. Therefore, it is necessary to improve the structure of existing solenoid valve plugs, providing a more rationally designed plug that is easier to disassemble and maintain, thus solving the aforementioned problems in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed solenoid valve plug that is easy to disassemble and maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
