Abstract: A multi-core connector used for 5G communication repeater, in which as a 5-core connector, with respect to prior art, an overall diameter is reduced from 32-35 mm to about 24.10 mm; the maximum external diameter is reduced from about 39.73 mm to about 27.

Abstract: An airtight RF coaxial connector with self-locking by snap-fastening comprises a plug connector and a socket connector, which is characterized in that the elastic locking element of the plug connector used for locking the socket outer conductor of the socket connector is fixed on the outer surface of the plug outer conductor of the plug connector along its radius; that the front end of the inner hole of the plug outer conductor of the plug connector is provided with a sealing groove; and that the sealing groove is provided with a sealing ring whose free inner diameter is shorter than the external diameter of the outer conductor of the socket connector. The chamfer at the front end of the socket connector makes pre-extrusion to the O-shaped sealing ring in the sealing groove. When the plug connector is further inserted into the socket, the conical surface on the locking bulge on the outer conductor of the socket connector re-extrudes the O-shaped sealing ring, and realizes a good sealing effect.

Abstract: 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.
