One-piece large tolerance radio frequency connector

Abstract

The invention discloses a one-piece large tolerance radio frequency connector. The one-piece large tolerance radio frequency connector comprises an outer conductor, an inner conductor and an insulator. The inner conductor comprises a main body, a conductive head and a spring, the inner conductor further comprises a positioning sleeve fixed in an inner hole of the conductive head, the positioning sleeve is cylindrical, an inner hole is formed in the rear end of the positioning sleeve, an outer convex barb is arranged on the outer circular wall surface of the rear end of the positioning sleeve,an inner convex barb is arranged on the inner hole wall surface at the front end of the main body, the front end surface of the outer convex barb abuts against the rear end surface of an inner convexbarb, and a gap is arranged between the outer circular wall surface of the outer convex barb and the inner hole wall surface of the main body. An annular protrusion is arranged on the inner hole wallsurface of the rear end of the conductive head, the front and rear end surfaces of the annular protrusion are chamfered or smooth circular arc surfaces, the annular protrusion of the conductive head is in sliding connection with the outer circular wall surface of the front end of the main body, and the front and rear end surfaces of the spring separately abut against the front end of the positioning sleeve or the front end of the conductive head and the rear end of an inner hole of the main body. The one-piece large tolerance radio frequency connector has excellent conductivity and good contact, ensures the requirement of broadband transmission, and realizes connection with small space and large tolerance.

Description

technical field [0001] The invention relates to a radio frequency connector, in particular to a tolerance radio frequency connector used for board-to-board interconnection in communication equipment, and belongs to the technical field of communication equipment connection. Background technique [0002] In the field of communication equipment connection, the traditional tolerance radio frequency connector used for board-to-board interconnection in communication equipment includes an outer conductor, an inner conductor and an insulator arranged between the outer conductor and the inner conductor; the inner conductor is The spring-type probe is formed by the three basic parts of the conductive head, the spring and the main body after being riveted by a precision instrument. The conduction path during operation is: conductive head → spring → main body. Since the diameter of the spring wire is much smaller than the cross-sectional area of ​​the conductive head and the main body, ...

AI Technical Summary

Problems solved by technology

Since the diameter of the spring wire is much smaller than the cross-sectional area of ​​the conductive head and the main body, and the spring material is spring steel, etc., the resistivity is high, so the heat is concentrated on the spring, but the spring tends to lose elasticity and fail at high temperature, resulting in poor contact, which cannot meet the use.
