Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a coaxial connector, and more particularly, to a coaxial connector having a sealing effect.

[0002]

[Prior art]

 Coaxial cable connectors are well known. The F-type coaxial cable connector is used to screw into the auxiliary interface connector to connect and integrate the coaxial cable with various electronic devices such as TV, CB and FM radio and other wireless electric systems. .

[0003] Known coaxial cable connectors have one drawback. The main function of the coaxial connector is to transmit electric signals through good coupling between the coaxial shield and the connector body. A known technical problem with coaxial connectors is the ingress of moisture into the connector body, ie, between the connector body and the interface connector. The F series connector shown in FIG. 1 is a typical coaxial cable connector known in the art. F The coaxial cable connector 10 includes a connector body 11, the connector body 11 having a shaft ring 12, a columnar means 13 coaxially disposed in the shaft ring 12, and a periphery of the columnar means 13. The nut 14 is provided. The connector 10 also comprises one sealing means 15, which is arranged between the inner surface of the nut 14 and the outer surface of the columnar means 13.

The connector 10 is combined with the coaxial cable by inserting the coaxial cable into the terminal end 16 of the connector body 11 and positioning the insulator and the center conductor of the coaxial cable in the columnar means 13. The braided shield and the outer sheath of the coaxial cable are arranged intermediate the outer surface of the columnar means 13 and the shaft ring 12. A compression force is applied to the shaft ring 12 using one hexagonal pressure welding tool to forcibly seal the coaxial cable with the outer sheath.

[0005] The combination of the F series connector 10 and the interface connector 17 has the following problems. First, there is a possibility that moisture may enter the threaded portion of the nut 14 and the interface connector 17 as indicated by reference numeral 18, which is brought about by the threaded connection. The penetration of moisture 102 between the electronic device 101 and the nut 14 can be eliminated by one rubber part 103. However, it was necessary to consider that such a solution required extra components to be installed, which would increase costs and assembly time.
