High-temperature-resistant non-welded type radio-frequency coaxial cable connector

Abstract

The invention discloses a high-temperature-resistant non-welded type radio-frequency coaxial cable connector which comprises an external conductor and a first inner conductor; the first inner conductor is sleeved with a high-temperature-resistant insulated support; a first limiting compensation step used for preventing the high-temperature-resistant insulated support from moving leftwards is arranged on the first inner conductor; the rear end of the first inner conductor is sleeved with a second inner conductor used for preventing the high-temperature-resistant insulated support from moving rightwards; the high-temperature-resistant insulated support is fixedly sleeved with a protective ring in a matched way; a second limiting compensation step used for preventing the protective ring from moving leftwards is arranged on the inner side wall of the outer conductor; and a check ring used or preventing the protective ring from moving rightwards is further fixedly arranged in the outer conductor. According to the radio-frequency coaxial cable connector, all parts are connected and fixed in a mechanical fixation mode, so that the reliability requirements of cable assemblies can be met.

Description

technical field [0001] The invention relates to a connector, in particular to a high temperature resistant non-welded radio frequency coaxial cable connector. Background technique [0002] The high temperature resistant non-welded radio frequency coaxial cable connector involved in the present invention is an important element for connection between defense weapon equipment systems. Because high temperature resistant radio frequency cable assemblies have special requirements for use in national defense weapon systems, for example, they can withstand high temperature environments, have good electrical performance indicators, and require high mechanical reliability. [0003] At present, some units in China have done some research on high temperature resistant radio frequency cable assemblies, but these methods are all realized by welding process; the welding process used in the prior art includes two kinds: one is commonly used solder welding, which Due to the limitation of t...

Problems solved by technology

[0003] At present, some units in China have done some research on high temperature resistant radio frequency cable assemblies, but these methods are all realized by welding process; the welding process used in the prior art includes two kinds: one is commonly used solder welding, which Due to the limitation of the melting point of solder, this method can only be used at about 200°C, which cannot meet the requirements of high temperature environment at all; and the electrical performance index is not high

The second is to use laser welding, that is, to use laser energy to locally heat the outer conductor of the connector and the radio frequency cable until it melts, and then cool and integrate; this method has high requirements for the operation process and is expensive. Laser welding equipment, welding cost is very high
