Abstract

The utility model discloses an intermediate connector for a coaxial cable, which comprises a lock pin. The outer wall of the lock pin is wrapped by a supporting shell, the supporting shell is wrapped by a two-way thread metal shell, and a fixing sheath is provided on the end portion of the supporting shell. The lock pin comprises a brass tube with axial openings on both ends. At least one ring-shape flange is arranged on the inner wall of the opening of the brass tube, thereby providing a circle contact surface between the lock pin and a center conductor connected with a coaxial cable. The utility model is characterized by the capability of being connected with coaxial cable of various types without doing damage to the inner conductor of the connecting cable, the capability for transmitting high frequency signal, strong restoring force and long useful life.

Description

The coaxial cable transition joint

Technical field

The utility model relates to a kind of coaxial cable transition joint.

Background technology

In the prior art, the coaxial cable transition joint generally comprises the lock pin that is used to connect coaxial cable core wire, and lock pin is provided with the plastics load-carrying covering outward, and the plastics load-carrying covering is fixed in the threaded metal shell again, and wherein the structure of lock pin has the following two kinds of forms that have:

One, lock pin is the punching type intermediate plate, and each intermediate plate is provided with the V-arrangement convex surface, and two intermediate plates form the biconvex connector, and advantage is: manufacturing technology is fairly simple; Shortcoming is: contact to the two point contact with inserting conductor, make that the trafficability characteristic of high-frequency signal is poor, Insertion Loss is big.

Two, lock pin is the punching type tubulose, two intrados connectors, and its advantage is: meet the high-frequency signal transmission requirement, Insertion Loss is little; Its shortcoming is: (1) and this body elasticity of the complete tube shape of contact force copper sheet that inserts inner wire, fatiguability; (2) than after the insertion of major diameter conductor, the tubulose copper sheet can't be returned to original closure fully, when inserting than the minor diameter conductor again, just can not form excellent contact, and useful life is short.

Summary of the invention

The utility model purpose is: a kind of coaxial cable transition joint is provided, and this connector can insert the coaxial cable of different model, and can not cause damage to the inner wire that inserts cable, meets the high-frequency signal transmission requirement, and restoring force is strong and useful life is longer.

The technical solution of the utility model is: a kind of coaxial cable transition joint, comprise lock pin, the lock pin outer wall is surrounded by load-carrying covering outward, load-carrying covering is surrounded by the bidirectional helical metal shell outward, there is fixed cover the end of load-carrying covering, and described lock pin comprises copper pipe, and the two ends of copper pipe are provided with axial opening, the copper pipe inwall of opening part is provided with a loop flange at least, and the center conductor contact-making surface that makes lock pin and incoming coaxial cable is a circumference.

The further technical scheme of the utility model is: a kind of coaxial cable transition joint, comprise lock pin, the lock pin outer wall is surrounded by load-carrying covering outward, load-carrying covering is surrounded by the bidirectional helical metal shell outward, there is fixed cover the end of load-carrying covering, and described lock pin comprises copper pipe, and the two ends of copper pipe are provided with axial opening, the copper pipe inwall of opening part is provided with a loop flange at least, and the center conductor contact-making surface that makes lock pin and incoming coaxial cable is a circumference; Described lock pin also comprises the intensive aspect that wraps at the copper pipe outer wall, and the center conductor and the connector of the same type center guide pin of the coaxial cable of access are obtained than the intrusion pull out force.

The utility model advantage is:

1. there is axial opening at the two ends of copper pipe of the present utility model, the contact-making surface of the center conductor of lock pin and incoming coaxial cable and connector of the same type center guide pin is a circumference, meet the high-frequency signal transmission requirement, can not cause damage the cable inner wire or the connector of the same type center guide pin of incoming coaxial cable.

2. copper pipe outer wall of the present utility model wraps intensive aspect and the lock pin carrying forms the structure with reinforcement restoring force, guarantee the coaxial cable of different model or the access of connector center guide pin, obtain stronger plug power, and can adapt to the diameter variation scope of the center guide pin of broad.

3. the utility model is fit to high-frequency signal transmission with the copper pipe through special process processing, and trafficability characteristic is good, and Insertion Loss is little; The outer wall of the utility model copper pipe is reinforced body and wraps, and restoring force is good, be difficult for tired old, long service life.
