Abstract
The utility model aims at putting forward a coaxial cable connector capable of realizing connection without a specialized pressing tool, so as to facilitate use of a user. The coaxial cable connector of the utility model comprises a casing; wherein a head end of the casing is provided with threads or connected with a nut, especially a tail end of the casing is provided with an anti-dropping inner flange; the casing is provided with a fixing sleeve capable of moving along an axial direction of the casing therein, a tail end of the fixing sleeve is provided with a tapered wedge structure which is protruded radially. During the process that a coaxial cable is inserted into the coaxial cable connector, a shielding layer and an outer sheath of the coaxial cable may deform under the effect of the tapered wedge structure and gradually protrude to form a protruding part, after the coaxial cable is inserted in place, the coaxial cable is pulled in a reverse direction, then the coaxial cable drives the fixing sleeve to slide towards a rear part of the casing together until an interference occurs between the protruding part and the anti-dropping inner flange, in this way, the coaxial cable can be prevented from dropping out, thereby achieving the purpose that the coaxial cable and the coaxial cable connector can be connected without the specialized pressing tool.
Description
Technical field
The utility model belongs to the CATV Technology field, specially refers to a kind of caxial-line feeder for connecting coaxial line and application apparatus.
Background technology
Traditional caxial-line feeder comprises the shell of metal material, and the end of shell is provided with screw thread, and the inside of shell is provided with central tube connector.In use, at first oversheath, screen and the insulating barrier of coaxial cable are clipped a part in succession, expose heart yearn, make the from inside to outside stepped distribution of termination of coaxial cable; Then heart yearn is inserted in the central tube connector together with insulating barrier, and screen and oversheath are inserted in the space between central tube connector and the shell, utilize at last professional wire pressing tool radial compression shell, make casing deformation, screen and oversheath are pressed on outside the central tube connector, thereby finish being connected of coaxial cable and caxial-line feeder; Utilize the threaded engagement of caxial-line feeder shell can be with coaxial cable and equipment connection.
Above-mentioned caxial-line feeder must use professional wire pressing tool could realize being connected of coaxial cable and caxial-line feeder, and it is convenient not to operate, and is not easy to very much installing and using of the laymans such as family.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to need not professional wire pressing tool and can realize the caxial-line feeder that connects, with user-friendly.
Caxial-line feeder of the present utility model comprises shell, and the head end of described shell is provided with screw thread or is connected with nut, and the tail end of crucial described shell is provided with anti-off-line inward flange; The inside of described shell be provided with can be along fixed cover from enclosure axis to activity, the tail end of described fixed cover is provided with the wedge structure of radial protrusion.
When connecting coaxial cable and caxial-line feeder, at first oversheath, screen and the insulating barrier of coaxial cable are clipped a part in succession, expose heart yearn, and oppositely screen is turned over and be enclosed within on the oversheath, make the from inside to outside stepped distribution of termination of coaxial cable; Then heart yearn is inserted in the fixed cover together with insulating barrier, and screen and oversheath are inserted in the space between fixed cover and the shell, insert in the process of caxial-line feeder at coaxial cable, the screen of coaxial cable and oversheath can deform under the effect of wedge structure, convex to form gradually lug boss, after coaxial cable inserts and puts in place, oppositely spur again coaxial cable, coaxial cable drives the rear portion that fixed cover slides to shell together, until lug boss and anti-off-line inward flange interfere, so just can prevent that coaxial cable from deviating from, reach and need not the purpose that professional wire pressing tool can be realized connecting coaxial cable and caxial-line feeder.
Further, the tail end of described fixed cover is provided with inner and outer tubes, and described wedge structure is located on the inner tube, is provided with containing cavity between the described inner and outer tubes; The diameter of described outer tube is greater than the internal diameter of described anti-off-line inward flange.When coaxial cable inserted, the screen of coaxial cable and oversheath can enter in the containing cavity like this, guarantee when reverse pulling coaxial cable, fixed cover can with the coaxial cable synchronizing moving, thereby guarantee that coaxial cable installs firm.
Further, the wedge structure of described inner tube is ring wedge, even the height of projection of wedge structure is less like this, also can make because of the cumulative function of ring wedge the whole height of screen and the formed lug boss of oversheath higher, guarantee that lug boss can interfere with anti-off-line inward flange, prevent that coaxial cable from deviating from, so just the height of projection of wedge structure can be designed less, be convenient to insert coaxial cable.
Further, the leading portion of described shell is provided with the Anti-slip cover inward flange, and the head end of described fixed cover is provided with outer step edge, and the outer step edge of described fixed cover is located at the front side of Anti-slip cover inward flange.Outer tube and outer step edge are located at respectively the both sides of Anti-slip cover inward flange, can prevent that fixed cover is by deviating from the shell.
That caxial-line feeder of the present utility model has is simple in structure, easy to operate, connect reliable characteristics, is fit to family expenses and specialty and installs and uses.
