Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.

[0021] like Figure 1-5As shown, the connector includes an outer conductor 2, a base 1 on one side of the outer conductor 2, a spring clip 3 fitted onto the outer conductor 2, and a terminal 5 inside the outer conductor 2. The terminal 5 is inserted into an insulator 6 and fixed to the outer conductor 2 by sealant 4. The front end of the terminal 5 is fixed in the insulator 6 and coaxial with the head of the outer conductor 2, forming the mating end of the connector. The bottom of the terminal 5 and the bottom of the outer conductor 2 form a surface mount structure or a through-hole soldering structure. A sealing ring 10 is also fitted onto the outer conductor 2. This electrical connector can be soldered onto a PCB, and the other end can be assembled with the housing connector, completing the functions of two connectors in one piece.

[0022] The outer conductor 2 has three countersunk holes to accommodate the insulator 6, and the frontmost countersunk hole has barbs 7 to fix the insulator 6 in the three countersunk holes. The outer side of the insulator 6 is in contact with the inner diameter of the countersunk hole, and each step surface is in contact with the plane of the countersunk hole, and is fixed in the countersunk hole of the outer conductor 2 by the barbs 7.

[0023] The outer conductor 2 has a snap-fit ​​area 8 on its outer ring adjacent to the base 1 for connecting the spring piece 3. The snap-fit ​​area 8 consists of a groove and a groove slope.

[0024] A groove 9 for connecting the sealing ring 10 is provided on the upper part of the outer conductor 2, close to the snap-fit ​​area 8.
