Abstract
The utility model discloses a self-locking feeder line fixing clamp, which comprises a screw and a clamp, wherein a mounting hole for mounting the screw is arranged in the middle of the clamp; one end of the clamp is provided with a bayonet, and the other end of the clamp is provided with a clamping seat; reinforcing ribs are arranged outside the clamp; the inner side of the clamp is provided with two anti-rotating holes and two anti-rotating ribs; and anti-skidding ribs are uniformly arranged in two holes which are used for mounting feeder lines. The self-locking feeder line fixing clamp is compatible with other feeder line clamps, the feeder lines are conveniently mounted and can be mounted on the existing U-shaped stainless steel pieces, the U-shaped stainless steel pieces are not required to be replaced in the existing system, the feeder lines are hardly loosened under the influence of such outdoor severe conditions as typhoons and own weight of cables, and the fixity of the cables is improved.
Description
Technical field:
The utility model relates to the fixing of feeder line in the antenna-feedback system of mobile base station, refers more particularly to self-locking feeder line holding clamp.
Background technique:
The outdoor iron tower in mobile base station is used for fixing the feeder line card of feeder line at present, mainly is made up of U-shaped stainless steel part and open type jig, and jig is made up of two cards, passes screw rod, fixes through the nut at screw rod two ends.One end of screw rod is fixed on the U-shaped spare, and the other end is vacant, is fixed by nut.
Mostly the employed main feeder cable in mobile base station is 7/8 ", 5/4 ", 13/8 " concentric cable; these elastic cable papers footpath is bigger, and weight is heavier, and the iron tower height is all more than 50 meters in addition; general single 7/8 " weight of cable is more than 50Kg; A system uses 6 cables at least, and the weight of all cables is carried by the feeder line jig, so the structure and material of jig all has influence on the safety of cable and the stability of communications system.
The open type jig is formed by two, and cable is stuck in wherein, and two jig aperture slots are less after the installation; Because abominable, the typhoon influence of outdoor conditions; The factor that also has the weight of cable own, after installation a period of time, the opening of two jigs can increase gradually; Cable begins to get loose, and influences the stationarity of cable.
Summary of the invention:
The purpose of the utility model provides the self-locking feeder line holding clamp that is difficult for getting loose after a kind of feeder line is installed.
The utility model is to realize like this; Self-locking feeder line holding clamp; Comprise screw rod, jig; It is characterized in that: be provided with mounting hole, an end that screw rod is installed in the middle of the described jig and be provided with that bayonet socket, the other end are provided with deck, arranged outside has stiffening rib, the inboard is provided with two anti-rotation holes, two anti-convulsions and installs in two holes of feeder line and evenly is provided with anti-skidding muscle.
The described jig of the utility model is two.
It is spring steel that the described bayonet socket of the utility model adopts material.
Compatible other feeder line jig of the utility model; Make things convenient for the installation of feeder line; Can be installed on the existing U-shaped stainless steel part, guarantee need not change the U-shaped stainless steel part in the existing system, can make feeder line under the influence of outdoor mal-condition such as typhoon and the weight of cable own; Be difficult for getting loose, improved the stationarity of cable.
Description of drawings:
Fig. 1 is the utility model and U-shaped spare installation diagram.
Fig. 2 is the utility model external structure.
Fig. 3 is the utility model cut-away view.
Fig. 4 is a partial view before the self-locking of the utility model bayonet socket.
Fig. 5 is a partial view after the self-locking of the utility model bayonet socket.
Among the figure 1, screw rod, 2 jigs, 21, bayonet socket, 22, stiffening rib, 23, mounting hole, 24, deck, 25, anti-skidding muscle, 26, the anti-rotation hole, 27, anti-convulsion.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing; Self-locking feeder line holding clamp; Comprise screw rod 1, jig 2; It is characterized in that: be provided with mounting hole 23, ends that screw rod 1 is installed in the middle of the described jig 2 and be provided with that bayonet socket 21, the other end are provided with deck 24, arranged outside has stiffening rib 22, the inboard is provided with two anti-rotation holes 26, two anti-convulsions 27 and installs in two holes of feeder line and evenly is provided with anti-skidding muscle 25.Described jig 2 is two.It is spring steel that described bayonet socket 21 adopts material.During practical implementation, screw rod 1 passes in the middle of two jigs 2, and the bayonet socket 21 on jig 2 is filled in the deck 24 of another jig 2; Buckle utilization elasticity in back own is installed opens automatically; The triangle bayonet socket can be stuck in the deck 24, can not get loose, and tightens the nut on the screw rod then; Tighten up jig, cable tightly is clipped between two jigs.After the installation, fit imperforation between two jigs and the cable fully; The phenomenon that endwisely slips, gets loose does not appear in the cable that big gravity is born in assurance; Guarantee the reliability that cable is fastening, the inboard equally distributed anti-skidding muscle of jig, prevent to be reppeared after cable from installing endwisely slips at present.Only when dismounting, press buckle, buckle just can get loose from deck, and two jigs could separately be pulled down cable.
