Embodiment
The embodiment of cable fixture provided by the invention is shown in shown in Fig. 1-Fig. 5, it comprises an adjustable scaffold and is fixedly mounted on three fastening clip for cables on this adjustable scaffold, can adjust the high and low position of fastening clip for cable and front and back position by adjusting adjustable scaffold, to adapt to the fixed position of the end that will clamp.
Adjustable scaffold comprises the fixed plate 4 being bent into L shape and the connecting plate 3 being bent into L shape, three fastening clip for cables walk abreast and are arranged on a side plate of fixed plate 4, another side plate of this fixed plate is bolted on a side plate of described connecting plate 3, the plate face of this biside plate is folded establishes, be bolted to connection together, the threaded mounting hole be wherein opened on fixed plate 4 is elongated hole, the length direction of this elongated hole is perpendicular to the side plate at fastening clip for cable place, when needing the front and back position adjusting fastening clip for cable, as long as along elongated hole direction after connecting plate 3 moves fixed plate to correct position lock bolt, if elongated hole is opened on connecting plate 3 and also can plays same effect certainly.In order to realize the adjustment of fastening clip for cable high and low position, by connecting plate 3 by being arranged on bolt on its another side plate and the slide block 7,8 of spinning on bolt is assemblied on two installation columns 1,2 that be parallel to each other, that have T-shaped guide groove, this two installations column is parallel relative to fastening clip for cable place side plate, and described T-shaped guide groove extends along installation strut length direction; In the present embodiment, installing column is a sheet-metal member, formed by after two sidewalls of the bending component of U-shaped profile again fold inward, opening is left between two turnover edges, such sidewall and turnover just define T-shaped guide groove along the space surrounded, and described slide block 7,8 embeds in corresponding T-shaped guide groove.When needing the high and low position adjusting fastening clip for cable, looser a bolt, connecting plate 3 is moved up and down to being applicable to behind position lock bolt again along guide groove, slide block and connecting plate corresponding clip are held on the outboard sidewalls on turnover edge, are fixed on installation column by connecting plate by the clamping force between slide block and connecting plate.
Cable fixture is when installing and using, by installing, column is parallel to be fixed on a supporting surface of the cable vault of high-tension switch cabinet, adjust before and after fixed plate 4 and high and low position according to end mounting point, fixed plate 4 also offers earth stud mounting hole, for installing cables head ground connection copper strips.
Above-mentioned fastening clip for cable comprises for realizing the holder 5 of clamping cables and folder lid 6 by locking device after involutory, holder has the V-shaped clamping groove 5-1 for clamped cable, two sidewalls of this clamping groove are respectively equipped with hollow molded cavity 5-2, and the hollow molded cavity on two side is symmetrically set, the involutory end face pressing from both sides lid 6 is provided with two protruding 6-2 of trapezoidal clamping that can insert corresponding hollow molded cavity when pressing from both sides lid and being involutory with holder, the V-type concave surface that the protruding relative face common combination of two clampings is formed presss from both sides the cable clamping face 6-1 covered, clamping groove on this cable clamping face and holder together form cable clamping space, this grasping part can change size with the change of the involutory distance of the folder relative holder of lid, both are at a distance of time far away, cable clamping space is larger, the cable that wire diameter is relatively large can be clamped, when becoming near apart, cable clamping space reduces, for clamping the relatively little cable of wire diameter.
In the present embodiment, holder 5 is two discrete components with folder lid 6, all by injection molding, holder is the base structure of a rectangle, and folder lid is the cover body structure of a hollow, and the protruding 6-2 of described clamping is arranged at folder lid the lid end, the edge all around of folder lid is that guiding is enclosed along 6-3, be slidably matched with the outer side surface of holder surrounding in folder lid with the involutory process of holder, play the guiding role, enclose along on be reserved with cable and dodge opening.
Locking device in the present embodiment adopts two lock bolts 9 to lock, and fastening clip for cable is also simultaneously be fixedly mounted on the fixed plate 4 of adjustable scaffold by this lock bolt 9, is thisly connected and fixed mode simple and fast.
In other embodiments of cable fixture of the present invention, the adjustable scaffold of the front and back and high and low position adjustment that can realize fastening clip for cable can have the structure of a variety of distortion, such as, in the present embodiment by column to fixed plate be by first up and down again before and after the counter structure that arranges of order, also can arrange by first front and back order upper and lower again, now the structure of each part should make adaptive change, and this change is the change that those skilled in the art need not pay performing creative labour and just can realize.In addition, in fastening clip for cable, the clamping groove 5-1 on holder can be arc-shaped slot pass; Two convex 6-2 of clamping that folder covers rise also can connect together becomes a clamping projection, and the cable clamping face that it is formed can be circular arc clamp face also can be plane clamp face.In addition, the hollow molded cavity 5-2 on the clamping groove two side on holder is not symmetrically set; Press from both sides the guiding covered to enclose along also not arranging.
The embodiment of fastening clip for cable provided by the invention is consistent with the fastening clip for cable structure adopted in each embodiment of above-mentioned cable fixture, will not repeat herein.
Fastening clip for cable of the present invention and cable fixture are specially adapted to high-tension switch cabinet, certainly also can be applicable in the occasion that is fixed cable at other and equipment.
