Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency connectors, in particular to a short-circuit-proof radio frequency connector. Background Art

[0002] An anti-short-circuit RF connector is a specially designed RF connector. Its main purpose is to prevent the occurrence of short circuits in a specific working environment, thereby ensuring the stability of signal transmission and the safety of equipment. Anti-short-circuit RF connectors usually have the following characteristics: anti-short-circuit design, high electrical performance, high mechanical performance and high reliability. Some existing anti-short-circuit RF connectors use two connectors with threaded connection to connect the lines, and some anti-short-circuit RF connectors use no protective mechanism to connect the connectors. This type of anti-short-circuit RF connector has some problems. For example, the threaded connection of the two connectors will cause the inner and outer conductors and contacts to rotate relative to each other for a long time, causing certain wear. At the same time, the threaded connection method requires the staff to connect for a long time. The anti-short-circuit RF connector without a protective mechanism limits the mechanical protection strength of the line connection and affects the airtightness of the line connection.
