Background technique

Coaxial cable connectors are well known knowledge. Coaxial cable connectors are typically coupled to electronic devices having threaded interface connectors, allowing the coaxial cable to be electrically integrated with various electronic devices.

Known coaxial cable connectors have some disadvantages. The main function of the coaxial connector is to ensure a good grounding contact between the connector body and the interface connector. The known technical problem of the coaxial connector involves whether the grounding of the connector body is good, that is, whether there is a good grounding contact between the connector body and the interface connector. The F-series connector shown in FIG. 1 can be used as a representative example of known connectors. The F-type connector includes a connector body 10, the connector body 10 includes an outer sleeve 11, an inner sleeve 12 is coaxially arranged in the outer sleeve 11, and a rotatable nut 13 is arranged in the inner sleeve. Around the cylinder 12. The connector body 10 can be used to mechanically and electrically connect a coaxial cable to the threaded interface connector 15 of the electronic device 14 .

There is an inherent problem in the combination of the F series connector body 10 and the threaded interface connector 15. The nut 13 cannot be completely combined with the threaded interface connector 15, leaving a gap between the inner sleeve 12 and the threaded interface connector 15. The uncontacted gap S, the gap S causes the grounding of the connector body 10 and the threaded interface connector 15 to deteriorate, thereby reducing the transmission performance of the electrical signal, resulting in poor contact therebetween that must be overcome.

Therefore, there is a need for a connector that can effectively and long-term ensure the ground contact between the connector body and the threaded interface connector to obtain good electrical characteristics.

Detailed ways:

Refer to Fig. 2 and Fig. 3, which show the three-dimensional section view and cutaway view of the coaxial cable connector of the present invention. The coaxial cable connector 20 includes a radially spaced coaxial inner and outer coaxial sleeves 21 , 26 coaxially receiving the coaxial cable; and a conductive grounding spring 30 . The front end of the inner sleeve 21 has an outer flange 22, a first interface portion 23, a second interface portion 24, and a rear end extension portion 25, the outer diameter and wall thickness of the rear end extension portion 25 are larger than the second The interface part 24 is small. The front end of the outer sleeve 26 has an outer sleeve body 27 and a rear end extension 28, the outer sleeve body 27 surrounds the second interface portion 24 of the inner sleeve 21, the outer diameter of the rear end extension 28 and The wall thickness is smaller than that of the outer sleeve body 27 , and forms a concentric surrounding relationship with the rear end extension 25 of the inner sleeve 21 , with an annular hollow in the middle. There is a nut 29 at the front end of the coaxial cable connector 20, and its end is an inner flange 291, and the inner flange 291 is clamped between the outer flange 22 and the outer sleeve body 27, and can be inside and outside The cylinders 21 and 26 are free to rotate, the inside of the nut 29 is threaded 292, and the outside is a hexagonal part, and the connector can be locked on the electronic device with a wrench or other tools.

As shown in FIGS. 4 and 5 , the conductive grounding spring 30 includes an inner annular portion 31 having a hole 32 whose diameter enables the spring 30 to be disposed around the first interface portion 23 of the inner sleeve 21 The edges become an adhesive bond.
