Embodiment
Embodiment one
Fig. 1, Fig. 2 and Fig. 3 are respectively that the end-view of crossing coil, A-A among the utility model first embodiment is to cutaway view, vertical view.As Fig. 1, Fig. 2 and shown in Figure 3, to cross coil and comprise skeleton 1, skeleton 1 is provided with cable-through hole 3, and cable-through hole 3 is used to allow cable to pass, and the shape of cable-through hole 3 can be circle, ellipse etc.Skeleton 1 can be installed on the line plate (for example line plate excessively of electrical equipment box), was tightly connected with the line opening of crossing of crossing the line plate.The side of skeleton 1 is provided with groove 5, and the width of groove 5 is corresponding with the thickness of crossing the line plate, be embedded in the groove 5 will cross the line plate, and more specifically, be that the edge of crossing the line opening that will cross the line plate was embedded in the groove 5 of coil.Those skilled in the art should recognize, groove 5 is just wherein a kind of will be crossed coil and be installed on the line plate, allow skeleton and a kind of mode that the line opening is tightly connected of crossing of crossing the line plate, and the coil of crossing of the present utility model is not limited to this mode.
This is crossed coil and also has soft protective jacket 7, soft protective jacket 7 connects with cable-through hole 3, soft protective jacket 7 and skeleton 1 integrated injection molding, be used to wrap up the cable that passes cable-through hole 3 away from an end of skeleton 1 having prevented the slit occurring between cable-through hole 3 and the cable, thereby prevent dust effectively, humid air etc. enters the electrical equipment box by the slit between cable-through hole 3 and the cable.In use, to cross coil and (for example be mounted to the line plate, the line plate excessively of electrical equipment box) line opening part excessively, then cable (for example power line, holding wire) is passed cable-through hole 3, then soft protective jacket 7 is lashed to cable away from the part of skeleton 1, thereby has prevented from the slit to occur between cable-through hole 3 and the cable.
As a kind of scheme, can the part away from skeleton 1 of soft protective jacket 7 be lashed to cable by materials such as rope, line bundles.In order to determine to tie up the position better and to fix rope or line is pricked, be provided with first on the surface away from the end of skeleton 1 of soft protective jacket 7 and tie up screens 8.Preferably, first ties up screens 8 is the flange around soft protective jacket 7 ends, and this flange can be continuous, also can be discontinuous.First ties up the location that screens 8 helps rope or line to prick, and can prevent effectively that rope or line bundle from coming off from soft protective jacket 7.
Preferably, soft protective jacket 7 is a rubber sleeve, and rubber sleeve has softness, waterproof, wear-resisting advantage, adopts the cross coil of rubber sleeve as soft protective jacket 7, can prevent effectively that dust, humid air, moisture content from entering the electrical equipment box.
Preferably, skeleton 1 also can be rubber or plastics, and the skeleton that these materials are made has certain elasticity, is convenient to the mistake coil was mounted to the line opening part excessively of line plate.In addition, skeleton 1 adopts identical or close material with soft protective jacket 7, can realize that skeleton 1 and soft protective jacket 7 are one-body molded, enhances productivity, and reduces production costs.
In the present embodiment, soft protective jacket 7 is a tubulose, and the aperture at two ends equates.But the utility model is not limited to this scheme.For example, soft protective jacket 7 can be the truncated cone shape, away from the aperture at skeleton 1 place less than aperture near skeleton 1 place.
Embodiment two
Fig. 4, Fig. 5 and Fig. 6 are respectively that the end-view of crossing coil, A-A among the utility model second embodiment is to cutaway view, vertical view.As Fig. 4, Fig. 5 and shown in Figure 6, similar with the mistake coil of embodiment one, the coil of crossing among the embodiment two comprises the skeleton 1 with cable-through hole 3 equally, is connected with soft protective jacket 7 on the skeleton 1 equally.Different places are that among the embodiment two, soft protective jacket 7 is the truncated cone shape, away from the aperture at skeleton 1 place less than aperture near skeleton 1 place.
Similarly, in order to determine to tie up the position better and to fix rope or line is pricked, be provided with first at soft protective jacket 7 away from the surface of the end of skeleton 1 and tie up screens 8.
As a kind of improvement project, can also be provided with second on the surface of soft protective jacket 7 and tie up screens 9.Like this, on the one hand, can select use first to tie up screens 8 or second according to the size of the cable that passes cable-through hole 3 and tie up screens 9.For example, when cable hour, can more easily soft protective jacket 7 be bundled on the cable by tie up screens 8 away from first of skeleton 1, therefore, can preferentially select for use first to tie up screens 8.On the other hand, can be as required, tie up screens 8 and second first simultaneously and tie up screens 9 and tie up, thereby increased the sealing of crossing coil 3 and cable, can prevent dust, prevent humid air more effectively.
Described in top embodiment one, soft protective jacket 7 can be a rubber sleeve, and skeleton 1 can be to be made by rubber or plastics etc.
A kind of improvement as technical scheme among the utility model the foregoing description one, the embodiment two and replacement technical scheme thereof, can also be symmetrically the second soft protective jacket be set in the other side of skeleton 1, similarly, this second soft protective jacket and cable-through hole 3 connect, one end and skeleton 1 are tightly connected, the other end be used to wrap up pass cable-through hole 3 cable to have prevented the slit occurring between cable-through hole 3 and the cable.This coil of crossing is preventing from the slit to occur between cable-through hole 3 and the cable crossing line plate both sides by two soft protective jackets, has further increased the sealing of crossing coil 3 and cable, can prevent dust, prevent humid air more effectively.
Embodiment three
Fig. 7, Fig. 8 and Fig. 9 are respectively that the end-view of crossing coil, A-A among the utility model the 3rd embodiment is to cutaway view, vertical view.As Fig. 7, Fig. 8 and shown in Figure 9, similar with the mistake coil of embodiment one, the coil of crossing among the embodiment three comprises the skeleton 1 with cable-through hole 3 equally, is connected with soft protective jacket 7 on the skeleton 1 equally.Difference is that soft protective jacket 7 is the truncated cone shape, away from the aperture at skeleton 1 place less than aperture near skeleton 1 place.Soft protective jacket 7 is an elasticity aperture 10 away from the end of described skeleton 1, and the diameter of flexible aperture 10 is less than the overall diameter of the cable that passes cable-through hole 3.Like this, in use, because the overall diameter of cable that passes cable-through hole 3 is greater than the diameter of elasticity aperture 10, therefore, elasticity aperture 10 will be wrapped under elastic acting force on the outer surface of cable, thereby realize having avoided the slit occurring between cable-through hole 3 and the cable, prevent that effectively dust, humid air from entering.
Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection range of the present utility model.
