Radio-frequency coaxial connector for cable television system

Abstract

The invention discloses a radio-frequency coaxial connector for a cable television system, which comprises an extrusion joint, an extrusion lining core and a rear extrusion sleeve, wherein an extrusion joint nut is arranged at one end of the extrusion joint in a sleeving manner; the extrusion lining core is arranged in the extrusion joint; one end of the extrusion lining core is in sealing connection with the extrusion joint nut; the rear extrusion sleeve is arranged at the other end of the extrusion joint in a sleeving manner; a connecting gap is formed between the extrusion lining core and the extrusion joint nut; a first seal washer is assembled in the connecting gap; and a second seal washer is arranged at a groove part of a threaded back of the extrusion joint nut. With the adoption of the mode, the connector can reduce signal failure brought by an assembly damage due to the fact that metal at a joint connecting part collides directly, and the silica gel washers which are additionally mounted among connecting pieces do not influence stress among the original assemblies, so that rotation is more uniform and smoother, a waterproof effect is exerted, short circuit of a signal due to the fact that water enters equipment connected with the joint for a long time is reduced, connected front-end equipment is prevented from being damaged, and the aging of the equipment is postponed.

Description

technical field [0001] The invention relates to the field of connectors for cable television, in particular to a radio frequency coaxial connector for cable television systems. Background technique [0002] Most of the F connectors used in radio and television systems are composed of metal three-piece sets, including the gap between the connection parts of the current extrusion connectors, which have not been paid much attention to. The collision between metals often damages the good connection between the components, and It does not have waterproof performance, and the network failure rate due to joint problems has not been well resolved. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a radio frequency coaxial connector for cable TV system, which can ensure the smoothness of the nut rotation during installation and use, and the waterproofness between the components after the connection is completed, and to a c...
