High-power tolerance blind-mating coaxial connector

Abstract

The invention relates to a high-power tolerance blind-mating coaxial connector. In the high-power tolerance blind-mating coaxial connector of the present invention, a socket inner conductor is installed in the mounting cavity of a socket outer conductor through an insulator, and the outer side wall of the insulator is in contact with the inner side wall of the socket outer conductor. In this way,the insulator fully fills the mounting cavity, and has large contact area between the insulator and the inner side wall of the socket outer conductor and between the insulator and the outer side wallof the socket inner conductor so as to well transfer heat. Especially in the case of high temperature generated by high power, the insulator allows the heat in the socket inner conductor to spread quickly.

Description

technical field [0001] The invention relates to a high-power tolerance blind-mating coaxial connector. Background technique [0002] RRU (remote radio unit) is an important part of the new generation of mobile communication base stations. Dual-frequency / multi-frequency RRU is an important product branch. This type of RRU has a higher power level for board-to-board RF connectors. Require. [0003] First of all, since the RF connector needs to transmit two or more carrier signals at the same time, the power level it needs to withstand is several times that of a single carrier; at the same time, the internal operating temperature of the RRU is relatively high (generally above 100 degrees Celsius). When several high-frequency signals work at the same time, the temperature of the inner conductor of the RF connector will rise rapidly. [0004] Existing board-to-board connectors cannot meet the requirements of long-term and reliable operation of dual-frequency / multi-frequency RRU...

AI Technical Summary

Problems solved by technology

[0009] There are many similar intellectual property rights, which are not listed here. From the current intellectual property rights and known technologies, none of them gives suggestions on how to improve the power withstand of board-to-board connectors.

All the above-mentioned patents and currently widely used board-to-board RF coaxial connectors mostly use materials such as PTFE or LCP as the insulating medium, because the thermal conductivity of this type of medium is relatively low 0.2 (W / m / k), and in the socket end, only to support the small contact area with the inner conductor and the outer conductor, so the heat of the inner conductor (the part with the highest temperature) cannot be effectively dissipated, and it is easy to fail under high temperature and high power working conditions
