Patent attributes
An airtight RF coaxial connector with self-locking by snap-fastening is disclosed. The front end of the plug outer conductor is in the shape of continuous circles, forming an overall ring; the front end of the plug outer conductor is provided with a ring-shaped bulge with right angle trapezoid shaped cross section, the hypotenuse of the trapezoid being faced with the front side of the socket connector, and the right angle side of the trapezoid being positioned normal to the longitudinal axis of the socket connector on the back side of the connector; the inner part of the socket connector is provided with a groove provided with a sealing ring; and the distance between the mid-point of the ring bulge and the front contact surface of the plug outer conductor corresponds to that between the mid-point of the groove and the front contact surface of the socket connector. The abolishment of the four-way slits at the front end of the plug outer conductor not only increases the stiffness of the outer conductor, but also decreases the leakage of RF. When the connector is in connection, the conical surface of the plug outer conductor will automatically extrude the sealing ring on the inner side of the socket outer conductor so as to realize ideal sealing effects.
