The socket includes a socket housing and a second sealing ring, a first thread is provided on the outer ring surface of the head section of the socket housing, a third groove is provided on the end surface of the tail section of the socket housing, and the first thread is provided on the end surface of the tail section of the socket housing. The second sealing ring is arranged in the third groove;

When the plug and the socket are in the plugged state, the head section of the socket housing is located in the gap between the connecting nut and the first annular boss, and the inner ring surface of the head section of the socket housing is in contact with the first sealing ring. The connection forms a seal, and the first thread and the internal thread of the connecting nut are threadedly matched.

Preferably, the number of the first grooves is two.

Preferably, a fuse hole is provided on the plug housing.

Preferably, a fuse hole is provided on the tail nut.

The beneficial effects of using the utility model are: the waterproof radio frequency connector product of the utility model has a novel structure, and the waterproof performance is greatly improved, and the first sealing ring is used in conjunction with the labyrinth structure formed by connecting the nut and the plug housing, thereby realizing the plug seat During the connection process, the utility model can be widely used in waterproof radio frequency connectors, and has a promising market prospect.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, Figure 2 and Figure 3, this embodiment provides a waterproof radio frequency connector, including a plug 1 and a socket 2;

The plug 1 includes a plug housing 11, a connecting nut 12, several first sealing rings 13, a retaining spring 14, a tail nut 15, a bushing 16 and a rubber sleeve 17, and the plug housing 11 has a hollow space inside. The cavity has a cylindrical shape, and the head section of the plug housing 11 is sequentially provided with several first grooves 111, a first annular boss 113 and a second groove 112, and the first sealing ring 13 is arranged in the first groove. In the slot 111; the connecting nut 12 is fixed on the outer ring surface of the head section of the plug housing 11 by a snap spring 14; a tail nut 15 is arranged outside the tail section of the plug housing 11, and the tail nut 15 is connected with the The plug housing 11 is connected by threads, and the tail nut 15 cooperates with the plug housing 11 to axially position the bushing 16 and the rubber sleeve 17 to realize waterproofing of the tail;

The socket 2 includes a socket housing 21 and a second sealing ring 22, a first screw thread 211 is provided on the outer ring surface of the head section of the socket housing 21, and a third screw thread 211 is provided on the end surface of the tail section of the socket housing 21. Groove 212, the second sealing ring 22 is arranged in the third groove 212;

When the plug 1 and the socket 2 are in the plugged state, the first thread 211 cooperates with the internal thread of the connecting nut 12, and the head section of the socket housing 21 is placed between the connecting nut 12 and the first annular boss 113 and the inner ring surface of the head section of the socket housing 21 abuts against the first sealing ring 13 to form a seal. When water tries to flow into the connector from the gap between the plug 1 and the socket 2, the plug housing 11, the connection The labyrinth structure formed by the nut 12 and the socket housing 21 makes it difficult for water to enter, and the waterproof performance is greatly improved by providing the first sealing ring 13 .
