Abstract
The utility model relates to a buckled type supporting strip for a cold-shrinking terminal of a cable, which comprises a supporting strip body, wherein a convex part is arranged on the edge of one side of the supporting strip body, and a concave part is arranged on the edge of the other side; the concave part and the convex part are mutually matched with each other in a buckled manner; the concave part and the convex part can be firmly mutually embedded with each other; a supporting pipe is formed by spirally winding the supporting strip. According to the buckled type supporting strip for the cold-shrinking terminal of the cable, edges of the supporting strip can be firmly connected together, and a comparatively low resistance is involved in detaching; the supporting strip body can be recovered into a strip-shaped article after using, therefore, recycling can be achieved, time and labor are saved, and operation is convenient.
Description
Technical field
The utility model relates to a kind of electric cable accessories product, is specifically related to a kind of cable shrinkage terminal and uses the buckle-type support bar.
Background technology
Cold contraction type electric cable accessories is a kind of electric cable accessories that leans on the elastic compression power of material with the butt joint of two cable joints, and along with being widely used of cable, cold contraction type electric cable accessories has also obtained using widely; When installing now, cold contraction type electric cable accessories is enclosed within after treatment cable end piece or joint, extracts inner strutting piece out and get final product; This strutting piece is a cylindric stay pipe that is formed by the support bar helically coiling; Only need spur the termination of support bar during dismounting, can directly stay pipe all be pulled out, existing support bar adopts heat-sealable way usually; Welding closely; But resistance is big when outwards extracting support bar, and is sometimes even the situation that support bar is broken occurs, very inconvenient.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of better performances is provided, and is time saving and energy saving during dismounting, cold contraction type electric cable accessories support bar simple to operate.
The utility model realizes that through following technical scheme the buckle-type support bar is used at a kind of cable shrinkage terminal, comprises the support bar body; One lateral edges of support bar body has recess; There is protuberance at the opposite side edge, the mutual buckle-type coupling of recess and protuberance, and recess and protuberance can closely be inlayed each other.
Further, described recess is a groove, and described protuberance is a raised line.
Further, described recess is the pit of equidistantly arranging, and described protuberance is the convexity of mating each other with pit.
Further, described pit is cylindrical pit, and described convexity is a cylindrical protrusions.
Further, described pit is the pit that the cross section is regular polygon, and described convexity is the columnar projections of regular polygon for the cross section.
The utility model is compared prior art and had the following advantages: the described cable shrinkage of the utility model terminal is provided with the concave-convex connecting portion of buckle-type with the buckle-type support bar because in support bar body both sides; Make and closely to inlay connection through the concave-convex connecting portion between the support bar edge; Resistance is little during dismounting, after finishing using, can let the support bar body be recovered to bar, thereby realizes recycling; Time saving and energy saving, easy to operate.

Among the figure: 1-support bar body, 2-recess, 3-protuberance, the easy-to-draw termination of 4-, 5-cold-contraction type coupling box, 6-cable.
Embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed execution mode and concrete operating process, but the protection range of the utility model is not limited to following embodiment.
As shown in Figure 1, be the structural representation of the embodiment one of the utility model, the cable shrinkage terminal described in the figure comprises support bar body 1 with the buckle-type support bar; One lateral edges of support bar body 1 is provided with protuberance 3; Protuberance 3 is a raised line, and there is recess 2 at the opposite side edge, and recess 2 is a groove; Recess 2 and protuberance 3 mutual buckle-type couplings, recess 2 can closely be inlayed with protuberance 3 each other.
As shown in Figure 2, be the front view of the embodiment two of the utility model, Fig. 3 and Fig. 4 are respectively left view and the A-A cutaway view of figure two; As can be seen from the figure; Described cable shrinkage terminal comprises support bar body 1 with the buckle-type support bar, and a lateral edges of support bar body 1 is provided with recess 2, and recess 2 is the cylindrical pit of equidistantly arranging; There is protuberance 3 at the opposite side edge, and protuberance 3 is the cylindrical protrusions of mating each other with pit.The recess 2 of described equidistant arrangement also can be the pit that the cross section is regular polygon, and in the case, protuberance 3 should corresponding setting become the cross section to be the columnar projections of regular polygon.The shape of recess 2 and protuberance 3 does not have special requirement, and no matter which kind of shape protuberance 3 is arranged to recess 2, can mate each other as long as can guarantee recess 2 and protuberance 3, and can closely inlay each other and get final product.
Fig. 5 is applied in the sketch map in the cold-contraction type coupling box process for the utility model; Support bar body 1 is spirally wound on the inner stay pipe that forms of cold-contraction type coupling box, is used for cold-contraction type coupling box 5 is strutted, and is provided with easy-to-draw termination 4 at an end of stay pipe; Cold-contraction type coupling box 5 is stretched out in easy-to-draw termination 4; Penetrate in 5 the stay pipe in the cold-contraction type coupling box at cable 6,, stay pipe is drawn back into support bar body 1 through the La Yila termination; Thereby whole stay pipe is pulled out cold-contraction type coupling box 5; After stay pipe was pulled out, cold-contraction type coupling box 5 shrank, and cold-contraction type coupling box 5 promptly closely sticks together with cable.
