A sealing gasket limiting groove is opened on the lower inside of the housing. A sealing gasket is fixedly connected inside the sealing gasket limiting groove. By opening a sealing gasket limiting groove on the lower surface of the housing, the sealing gasket is limited and fixed, so that when the high-protection solenoid valve plug is plugged into an external socket and locked, the sealing gasket will not be squeezed out under pressure, thus ensuring the waterproof performance of the high-protection solenoid valve plug.

[0008] Furthermore, the plug portion tapers inward from top to bottom along the outer radial direction to form a stepped structure with the housing, which improves the connectivity of the high-protection solenoid valve plug during insertion.

[0009] Furthermore, the outer surface of the plug portion is provided with evenly distributed positioning grooves to position the high-protection solenoid valve plug during insertion.

[0010] Furthermore, the last positioning groove is a square positioning groove, while the other positioning grooves are semi-circular positioning grooves, to prevent damage to the pins caused by incorrect insertion of the high-protection solenoid valve plug.

[0011] Furthermore, the housing and the plug-in part have vertical through-holes, and the inside of the positioning hole is threaded with a positioning bolt. After the high-protection solenoid valve plug is plugged in, it is locked.

[0012] Furthermore, it also includes an insulating protective layer, which is fixedly connected to the right side of the outer surface of the wire core to protect the wire core.

[0013] Furthermore, the lower surface of the housing is provided with a receiving groove, so that the sealing gasket has a receiving space when deformed, thereby improving the overall sealing effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-protection solenoid valve plug has the following advantages:

[0015] By creating a sealing gasket limiting groove on the lower surface of the housing, the sealing gasket is limited and fixed, ensuring that the sealing gasket will not be squeezed out under pressure when the high-protection solenoid valve plug is plugged into and locked with an external socket, thus ensuring the waterproof performance of the high-protection solenoid valve plug.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-5 The embodiment provides a technical scheme: a high-protection-performance electromagnetic valve plug, which comprises a shell 1;

[0024] Housing 1: A plug-in part 6 is fixedly connected to its lower interior. The plug-in part 6 tapers from top to bottom outwards, forming a stepped structure with the housing 1. The outer surface of the plug-in part 6 has evenly distributed positioning grooves 5, with the last one being a square groove and the others being semi-circular. The positioning grooves 5 are aligned with the positioning blocks on the external socket, and the plug-in part 6 is inserted into the external socket. Vertically penetrating positioning holes 10 are formed inside the housing 1 and the plug-in part 6. Positioning bolts 4 are threaded into the positioning holes 10. Rotating the positioning bolts 4 causes the lower thread of the positioning bolts 4 to enter the threaded hole on the external socket, thus tightly connecting the high-protection solenoid valve plug to the external socket. Evenly distributed insertion holes 12 are fixedly formed inside the plug-in part 6, and each insertion hole 12 is fixedly connected to a pin. 7. Connect the lower end of the pin 7 to the contact point inside the external socket. The upper end of the pin 7 is fixedly connected to the wire core 9. The wire core 9 extends through the inside of the housing 1 to the right side of the housing 1 and also includes an insulating protective layer 3. The insulating protective layer 3 is fixedly connected to the right side of the outer surface of the wire core 9 (the insulating protective layer 3 can be a rubber insulating layer). A sealing gasket limiting groove 11 is opened on the lower side of the inside of the housing 1. A sealing gasket 8 is fixedly connected inside the sealing gasket limiting groove 11 (the sealing gasket limiting groove 11 is T-shaped, the sealing gasket 8 is I-shaped, and the sealing gasket 8 can be a rubber sealing gasket). A receiving groove 2 is opened on the lower surface of the housing 1. The high-protection solenoid valve plug and the external socket squeeze the sealing gasket 8. The deformed part of the sealing gasket 8 enters the receiving groove 2, thereby ensuring the sealing effect of the sealing gasket 8 and providing the protection performance of the high-protection solenoid valve plug.

[0025] The working principle of the high-protection solenoid valve plug provided by this utility model is as follows: When using the high-protection solenoid valve plug, the positioning groove 5 is aligned with the positioning block on the external socket, and the plug part 6 is inserted into the external socket, so that the lower end of the pin 7 is connected with the contact point in the external socket. The positioning bolt 4 is rotated so that the lower end of the positioning bolt 4 is threaded into the threaded hole opened on the external socket, thereby making the high-protection solenoid valve plug tightly connected to the external socket. At the same time, the high-protection solenoid valve plug and the external socket squeeze the sealing gasket 8, and the deformed part of the sealing gasket 8 enters the receiving groove 2, thereby ensuring the sealing effect of the sealing gasket 8 and providing the protection performance of the high-protection solenoid valve plug.
