FIG. 1 is a schematic diagram of the present invention.

Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, a radio frequency socket connector includes a housing 1 having a socket end and a tail end, and a jack 2 disposed at the socket end of the housing 1, wherein the socket end is used for plugging with other connectors or device connectors, the tail end is used for connecting a cable, the jack 2 is used as a female head for plugging, and is matched with a male head having a corresponding pin to transmit signals in a connection state. The outer side of the middle part of the shell 1 close to the socket end is provided with a fixing plate 8 which is fixedly connected with equipment.

The jack 2 is equipped with first insulating cover 3 with the casing 1 is radial within a definite time, and the inner of first insulating cover 3 is equipped with second insulating cover 4 with the inner of jack 2 is radial within a definite time, and first insulating cover 3 and second insulating cover 4 are isolated with jack 2 whole and casing 1, are playing fine insulating effect with the center of jack 2 fixed casing 1. The second insulating sleeve 4 is hollow cylindrical and is provided with an annular protruding part 41 at one end close to the socket end of the shell 1, the cable can be stripped section by section when the connector is connected, the front end is a conductor, then a medium, then a shielding layer and finally an outer layer of the cable, the second insulating sleeve 4 and the first insulating sleeve 3 are arranged at the interval between the conductor of the cable and the shell 1 when the conductor of the cable is connected with the jack 2, and the second insulating sleeve 4 and the first insulating sleeve 3 are also arranged at the interval between a medium department at the rear end of the conductor of the cable and the shell 1, so that the insulating effect at the joint of the cable and the jack 2 is good, and the cable is high-voltage resistant.

Be equipped with the bush 5 that is used for connecting the cable shielding layer in casing 1, bush 5 adopts stainless steel, the 5 side of bush is connected with the shielding layer of cable, the tail end of casing 1 is provided with gland nut 6 and packing ring group 7, when gland nut 6 was screwed up with casing 1, bush 5 was compressed tightly in casing 1 by gland nut 6 and packing ring group 7, thereby can be with one section and the 1 fastening connection of casing in casing 1 of cable, guarantee the firm in connection of cable and connector.
