Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a double-sealed connector. Background Technology

[0002] Connectors, also known as connectors or sockets in China, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. The male and female terminals can transmit information or current after contact, hence the name connector.

[0003] In the prior art, patent publication number CN202321867791.9 discloses a connector male terminal and an electrical connector, including a male terminal housing that extends through a mounting cavity along the axial direction and a male connector installed in the mounting cavity. The male connector is characterized in that it includes an insulating part inserted into the mounting cavity and at least partially exposed forward in the mounting cavity along the insertion direction, and a terminal part disposed on the exposed end of the insulating part. A cable is inserted into the insulating part from one end of the mounting cavity corresponding to the exposed end facing away from the insulating part, and one end of the terminal part passes inward through the corresponding position of the insulating part and is connected to the cable.

[0004] The connectors mentioned above have some problems in actual operation, such as the lack of an effective sealing structure, a high failure rate when working in harsh environments, and cumbersome assembly. Therefore, we propose a double-sealed connector. Utility Model Content

At this time, according to the guidance of the guide bar 48 and the guide groove 49, it is firmly inserted. At this time, the lower end of the insert 1 is inserted into the annular slot 32. Then, the lifting plate 46 is released, and the spring 4 is activated. Due to the elastic force of spring 3, the two springs 43 push the movable plug plate 44, causing the movable plug plate 44 to move to the left side of the slide groove 42. At this time, the locking pin 45 is inserted into the inside of the cylindrical slot 47. At this time, the upper sealing ring 34 is fitted tightly on the lower rubber contact surface 33, and the lower sealing ring 31 is fitted tightly on the upper rubber contact surface 35.
