Problems solved by technology
This kind of coaxial contact cannot realize the complete shielding of the inner conductor, and the signal transmitted in the contact is easily affected by the outside world, and at the same time, it cannot realize the airtightness inside the outer conductor
In addition, the contacts transmit signals through coaxial cables. In a multi-core connector, many coaxial cables will take up a lot of space.

The invention relates to a radio frequency (RF) coaxial connector comprising a casing on which a contact element arrangement hole is formed, wherein a contact element, which comprises an external conductor, is fixedly inserted in the contact element arrangement hole; an internal conductor, which is fixed in the external conductor through an insulator, is arranged in the inner hole of the external conductor; the front end of the contact element is used for the insertion of a matched contact element; the back end of the contact element is fixedly provided with a glass seal component which is made of glass and forms a shielding cavity through the matching with the external conductor; a transfer conductor penetrates through the middle of the glass seal component; the inner end of the transfer conductor is connected with the internal conductor; and the outer end of the transfer conductor is connected with a circuit. In the invention, the back end of the contact element is provided with the glass seal component which forms a shielding cavity through the matching with the external conductor, and the transfer conductor arranged in the glass seal component connects the internal conductor and the circuit. Thus, a completely shielding cavity is formed in the external conductor, thereby realizing good electromagnetic shielding and air-tight seal, and effectively preventing signals transmitted in the contact element from being subjected to external electromagnetic interference.
