Coaxial contact element and electric coupler using same

Abstract

The invention discloses a coaxial contact element and an electric coupler using the same. The coaxial contact element comprises an inner conductor and an outer conductor, wherein the front end of the outer conductor is provided with a canular outer conductor splicing end arranged around an inner conductor splicing end; the outer diameter of the canular outer conductor splicing end is bigger than one subsequent integrally-extending part thereof so as to form a first convex annular table structure on the front end of the outer floating conductor; the outer wall of the outer conductor is provided with a second convex annular table structure in the position far away from the splicing end; the outer wall of the outer conductor is successively sheathed with a spring and a sliding sleeve from front to back between the corresponding annular end surface of the first annular table structure and the second annular table structure; the outer wall of the sliding sleeve is provided with an axially-fixed bulge which is detachable with the corresponding structure in the case of an adaptive connector. The contact element of the invention can realize tight inserting and contact under the action of spring force, and the electrical length of the connector does not change so as to realize the phase stabilizing function of the connector and improve the anti-vibration performance and the impact performance of the connector.

Description

technical field [0001] The invention relates to the technical field of electrical connectors. Background technique [0002] In order to achieve standardization, detachability and interchangeability of electrical connectors for transmitting medium and high frequency radio frequency signals, some of these connectors use separately produced coaxial contacts and connector housings with contact mounting channels for assembly combination , this type of contact should at least include a metal sleeve-shaped outer conductor for signal shielding, a central needle-shaped inner conductor in the outer conductor (it can be a pin or a jack), and a filling between the inner and outer conductors. The insulator should also have a structure to cooperate with the mounting channel in the connector housing. The inner conductors and outer conductors of a pair of coaxial contacts have a male-female intersecting structure respectively. The ideal mating condition of such contacts is that the inner a...

AI Technical Summary

Problems solved by technology

The inner conductors and outer conductors of a pair of coaxial contacts have a male-female intersecting structure respectively. The ideal mating condition of such contacts is that the inner and outer conductors are mated in place at the same time and meet the electrical connection length. requirements, but most of the inner and outer conductors of the existing coaxial contacts are rigid integral structures, and the processing errors of the contacts and the connector housing are unavoidable. The barrier between each other will affect the tight mating and electrical connection length of the inner and outer conductors
