Abstract

The utility model relates to a torsion sleeve and especially a torsion sleeve used for installation of a radio-frequency coaxial connector. The torsion sleeve includes a torsion head. The top end of the torsion head is provided with a front blocking tooth. The tail end of the torsion head is connected with a torsion sheet in an arc transition manner. A torsion groove is arranged outside the torsion sheet. A rear blocking tooth is arranged on the tail end of the inner side of the torsion sheet. The tail end of the rear blocking tooth is provided with a slope body. The torsion sleeve provided by the utility model is made of ABS (Acrylonitrile-Butadiene-Styrene). When using, a nut is sleeved into the torsion sleeve. The front blocking tooth and the rear blocking tooth of the torsion sleeve block the nut. Then the nut can be screwed into the radio-frequency coaxial connector through rotating the torsion sheet. The torsion sleeve is convenient in operation, easy for installation and is time-saving and labor-saving.

Description

A kind of torsion cover

Technical field

The utility model relates to the torsion cover, in particular for the torsion cover of radio frequency (RF) coaxial connector installation.

Background technology

Radio frequency (RF) coaxial connector is installed on the cable usually, and the element as transmission line is electrically connected or separates mainly serves as a connection.The subject matter that existing radio frequency (RF) coaxial connector exists when mounted is: when the nut precession, because the space is narrow and small, and the head volume of connector is also less, cause and be difficult for rotating, cause nut to be difficult for being installed on the connector, it is very loaded down with trivial details to operate, and wastes time and energy.

Summary of the invention

The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, easily makes nut precession, easy and simple to handle, time saving and energy saving torsion cover.

The utility model is achieved through the following technical solutions:

A kind of torsion cover, its special character is to comprise torsion head 1, torsion head 1 top is provided with front tooth 4, torsion head 1 terminal arc transition is connected with torsion sheet 2, torsion sheet 2 outsides are provided with torsion groove 3, and torsion sheet 2 inside end are provided with backstop tooth 5, and backstop tooth 5 ends are provided with slope body 6;

Described torsion cover adopts acrylonitrile-butadiene-styrene copolymer to make;

The cross sectional shape of described front tooth 4 is rectangle;

The cross sectional shape of described backstop tooth 5 is isosceles triangle, and the drift angle angle of isosceles triangle is 60 °.

Torsion cover of the present utility model, adopt acrylonitrile-butadiene-styrene copolymer (being called for short ABS) to make, during use nut is inserted in the torsion cover, the forward and backward retaining tooth of torsion cover blocks nut, this moment just can be by rotating the torsion sheet with nut precession radio frequency (RF) coaxial connector, easy to operate, easily install, time saving and energy saving.

Embodiment

Provide embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described in further detail.

The torsion cover of present embodiment comprises torsion head 1, and torsion head 1 top is provided with front tooth 4, torsion head 1 terminal arc transition is connected with torsion sheet 2, torsion sheet 2 outsides are provided with torsion groove 3, and torsion sheet 2 inside end are provided with backstop tooth 5, and backstop tooth 5 ends are provided with slope body 6; The torsion cover adopts acrylonitrile-butadiene-styrene copolymer to make; The cross sectional shape of front tooth 4 is rectangle; The cross sectional shape of backstop tooth 5 is isosceles triangle, and the drift angle angle of isosceles triangle is 60 °.

Operation principle: at first nut is inserted in the torsion cover, for the ease of being inserted in, end at the backstop tooth is provided with the slope body, the forward and backward retaining tooth that arranges makes that nut can only be movable in this space, just can be installed in nut on the radio frequency (RF) coaxial connector this moment, for the ease of using erecting tools, on the torsion sheet, also be provided with the torsion groove.

The unspecified content of the utility model is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection range of the present utility model should be determined according to the protection range of claim.
