Abstract

The invention relates to a communication device, in particular to a self-tightening type feeder line connector. The self-tightening type feeder line connector is composed of a nut, a copper protection sleeve and a movable lining core. The nut is provided with matched threads and a groove, wherein the matched threads and the groove are used for being connected with a device. A third annular flange is arranged on the periphery of the tail end of an outlet cylinder of the copper protection sleeve and is movably arranged in the groove in a clamping mode, a first annular flange extending inwards in the radial direction is arranged at the inlet end of the copper protection sleeve, and the inner diameter of the first annular flange is larger than the outer diameter of the inlet end portion of the movable lining core. The movable lining core can movably penetrate through the outlet cylinder of the copper protection sleeve, the inlet end of the movable lining core is embedded in the copper protection sleeve, the outlet end of the movable lining core is embedded in the nut, a clamping groove is formed in the peripheral face of the portion, embedded in the copper protection sleeve, of the movable lining core, a second annular flange is arranged on the periphery of the outlet end of the movably lining core, and the movement range of the movable lining core is limited through a snap spring and the second annular flange. The self-tightening type feeder line connector has the advantages that connection can be completed without using pressing connection tools, and automatic locking can be achieved. The self-tightening type feeder line connector is widely applied to the industries of radio and television networks and communication.

Description

technical field [0001] The invention relates to a communication device, in particular to a feeder connector. Background technique [0002] In the prior art, feeder joints are used for feeder connections of cable broadcasting, television, and networks, and special tools must be used for crimping and extrusion during connection, that is, tools are required for seamless connection operations. If the connection operation is carried out at high altitude or in a hidden corner of the project, it is not easy to use tools for operation, and there are many tools, which is quite troublesome. The connection method is quite cumbersome, delays the construction period, and the labor cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a self-tightening feeder joint, which has the advantage of being able to achieve the purpose of connection without crimping tools, and has the function of automatic locking. [0004] The object of the present ...
