Abstract

The utility model belongs to a microwave communication device and relates to a structure of a radio frequency coaxial connector, in particular to a coaxial connector capable of quickly inserting, pulling and self-locking. The coaxial connector comprises a coaxial socket and a coaxial plug that are matched with each other; the external conductor of the coaxial plug is inserted into the external conductor of the coaxial socket; the internal hole wall of the external conductor of the coaxial socket is provided with an annulus inserting slot which is internally inserted by an elastic inserting ring; the internal edge of the elastic inserting ring is provided with an elastic inverted tooth sheet which is inclined towards the internal side of the coaxial socket in the axial direction; the periphery of the external conductor of the coaxial socket is sheathed by a sliding sleeve which can move axially; the internal side of the front section of the sliding sleeve is provided with a conical surface which is attached to the root part of the inclined elastic inverted sheet; the insertion section of the external conductor of the coaxial plug is provided with an annulus lug, the diameter of which is more than that of the rear section; and furthermore, the radius from the tip of the elastic inverted tooth sheet to the axle center of the connector is less than the maximum radius of the annulus lug when the elastic inverted tooth sheet is in a free state. The coaxial connector has simple structure, convenient and quick installation and separation, and is not easy to be desquamated under the connected state.

Description

Fast plugging self-locking coaxial connector

Technical field

The utility model belongs to microwave communication device, relates to the structure of radio frequency (RF) coaxial connector, specifically is a kind of fast plugging self-locking coaxial connector.

Background technology

Common radio frequency (RF) coaxial connector generally comprises coaxial socket and the coaxial plug that cooperatively interacts, in connection procedure,, need it be locked by securing member or other syndetons usually in order to guarantee the difficult disengagement of back two parts of pegging graft, make complex installation process, installation effectiveness is low.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of simple in structure, installation and convenient separation quick, and under connection status the fast plugging self-locking coaxial connector of difficult drop-off.

Fast plugging self-locking coaxial connector of the present utility model includes coaxial socket and the coaxial plug that cooperatively interacts, the outer conductor of coaxial plug is inserted in the outer conductor of coaxial socket, have the draw-in groove of annular on the inner hole wall of the outer conductor of coaxial socket, card has a snap ring, the inner edge of snap ring to be provided with to the axially inboard elasticity pawl sheet that tilts of coaxial socket in draw-in groove; Being with one in the outer conductor periphery of coaxial socket can axially movable sliding sleeve, the leading portion inboard of sliding sleeve has the conical surface that can fit with the elasticity pawl sheet root of above-mentioned inclination, when sliding sleeve to coaxial socket axially in side direction when moving, the above-mentioned conical surface can be oppressed elasticity pawl sheet to change its angle of inclination, makes the outer conductor inwall of the close more coaxial socket in its tip; The insertion section of the outer conductor of described coaxial plug has the annular projection of one section diameter greater than its back segment, and the radius in above-mentioned elasticity pawl sheet elasticity pawl sheet tip to connector axle center under free state is less than the maximum radius of annular projection.

Be provided with the conductive silicon cushion rubber between the insertion section outer wall of the outer conductor of described coaxial plug and the coaxial socket outer conductor inwall.

The utility model is simple in structure, easily manufactured.Insert that annular projection on the outer conductor of coaxial plug in the coaxial socket process can be oppressed and by elasticity pawl sheet at coaxial plug, annular projection is by behind the elasticity pawl sheet, elasticity pawl sheet utilizes elasticity to automatically reset, with its tip towards annular projection, the coaxial plug of insertion can't be deviate from, realize self-locking; When needs are transferred to coaxial plug, only need to utilize and promote moving axially of sliding sleeve, make the conical surface of sliding sleeve leading portion can oppress elasticity pawl sheet to change its angle of inclination, no longer stop annular projection until the tip of elasticity pawl sheet, coaxial plug can freely be transferred to.Its plug process is simple and convenient, operation is reliable.
