Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency connectors, in particular to a vibration-resistant and waterproof connector. Background Art

[0002] Radio frequency coaxial connector (hereinafter referred to as RF connector) is generally considered to be a component installed on a cable or installed on an instrument, as a component for electrically connecting or separating transmission lines. It belongs to mechatronics products. Simply put, it mainly plays a bridging role.

[0003] 1. The existing RF coaxial plug connector flange is fixed to the wall by 4-Φ3.2 screw holes. When the use environment is a vibration environment, the screws are easy to back out, causing the product docking surface to become a stress point. 2. The sealing and shielding performance is poor. The mechanical dimensions of the connector shell, connector center conductor, and connector insulator are matched and fixed. Affected by the ambient temperature, the sealing performance between the connector shell and the wall is easily reduced. The connector flange is fixed to the wall with screws, and it is difficult to avoid gaps on the contact surface. These tiny gaps affect the overall shielding performance and water vapor infiltration; and there is no blocking glue inside. Once water vapor enters the product, it will directly affect the insulation resistance, withstand voltage or other electrical performance of the entire link. 3. The center conductor of the connector is fixed with a barbed structure. When connecting thin cables, it will cause damage to the cable connection or break the circuit. Utility Model Content
