Abstract

The utility model relates to a radio frequency coaxial connector which comprises a shell and a nut, wherein an inner connection pipe is coaxially arranged on the shell, and an O-shaped circle is sleeved on the left outside of the inner connection pipe. The material quality of the O-shaped circle is silica gel. The nut is inserted into the inner connection pipe and is connected with the shell in a movable mode within 360 degrees. Clamp rings and flat rings are arranged sequentially from the right to the left at the right end of the connector in a pressed mode, the inside of the shell and the outside of the inner connection pipe. A toothed washer is arranged on the left side of the flat washer. The toothed washer is a fully fashioned internal toothed washer. A round of groove is arranged on the shell, and a round of skidproof leather collar is arranged on the grooves. The radio frequency coaxial connector changes the prior crimping tools, and can insert the stripped cable directly into a joint and the cable is fixed tightly through the internal toothed washer inside the joint, thereby tensile force of 150 N can be achieved and the joint can be kept from dropping. The radio frequency coaxial connector is reliable in connection, good in vibration resistance and mechanical and electrical properties and can be widely used in radio apparatus and instrument for connecting the radio cable.

Description

A kind of radio frequency (RF) coaxial connector

Technical field

The utility model belongs to microwave communication device, relates to a kind of connector, specifically a kind of radio frequency (RF) coaxial connector.

Background technology

Wide in variety, the purposes of radio frequency (RF) coaxial connector is wide, consumption is very large, a plurality of fields have been widely used at present, common radio frequency (RF) coaxial connector generally is that coaxial socket and the plug that cooperatively interacts arranged, in connection procedure, electric wire is easy to come off, usually need other securing member to be fixed, complex installation process, inefficiency.

Summary of the invention

In order to address the above problem, the utility model provides the coaxial connector of a kind of installation and convenient separation.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The utility model is a kind of radio frequency (RF) coaxial connector, comprise shell and nut, be coaxially arranged with in the enclosure inner connecting tube, cover has an O type circle in the inner connecting tube left end outside, nut inserts inner connecting tube and becomes 360 degree to be flexibly connected with described shell, in the inboard of the right-hand member of connector, shell, the outside of inner connecting tube is pressed into successively from right to left and is provided with compacting ring and plain washer, also is provided with a toothed washer in the left side of plain washer.

Further improvement of the utility model is: toothed washer is one-time formed internal tooth packing ring.

Further improvement of the utility model is: also be provided with a circle groove on shell, the anti-skidding apron of a circle is set in groove.

Further improvement of the utility model is: O type circle is the silica gel material.

The beneficial effects of the utility model are: it has changed original crimping tool the utility model, can directly the cable that strips be inserted joint, by the internal tooth packing ring in the joint that cable is firmly fixing, thereby can reach the pulling force of 150N, joint does not come off, and at O type circle hold-doun nut, guarantees that the nut free gap is good, do not rock, the apron that arranges on the shell prevents the workman, and hand is sliding and cause unnecessary trouble when mounted.

The utility model connects reliable, and good anti-vibration, machinery and excellent electrical properties are widely used in wireless device and are connected with instrument and connect radio frequency cable and use.
