For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cold-shrink type cable termination is provided, comprise: core layer, insulating barrier, semi-conductive layer, stress tube and shrinkage sleeve pipe, described core layer is outside equipped with insulating barrier, described insulating barrier is outside equipped with semi-conductive layer, described stress tube is arranged on insulating barrier and the semi-conductive layer, described shrinkage sleeve pipe is arranged on outside stress tube and the semi-conductive layer, also be provided with tube connector between the described semi-conductive layer, be provided with support bar in the described tube connector.
In preferred embodiment of the utility model, described semi-conductive layer is installed in the tail end of insulating barrier.
In preferred embodiment of the utility model, the afterbody of described stress tube contacts setting with semi-conductive layer.
In preferred embodiment of the utility model, described shrinkage sleeve pipe is installed on the partial lateral of stress tube and semi-conductive layer.
In preferred embodiment of the utility model, described shrinkage sleeve pipe is gum sleeve.
In preferred embodiment of the utility model, described tube connector is arranged between the tail end semi-conductive layer of cable, and described support bar is vertical setting in tube connector.
The beneficial effects of the utility model are: the utility model cold-shrink type cable termination has good water-tight performance, has guaranteed the reliability of long-time running, and whole installation process need not tool using, and is more simple and efficient, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model cold-shrink type cable termination one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, core layer, 2, insulating barrier, 3, semi-conductive layer, 4, stress tube, 5, the shrinkage sleeve pipe, 6, tube connector, 7, support bar.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises:
A kind of cold-shrink type cable termination, comprise: core layer 1, insulating barrier 2, semi-conductive layer 3, stress tube 4 and shrinkage sleeve pipe 5, described core layer 1 is outside equipped with insulating barrier 2, described insulating barrier 2 is outside equipped with semi-conductive layer 3, described stress tube 4 is arranged on insulating barrier 2 and the semi-conductive layer 3, and described shrinkage sleeve pipe 5 is arranged on outside stress tube 4 and the semi-conductive layer 3.
Wherein, described semi-conductive layer 3 is installed in the tail end of insulating barrier 2, and the afterbody of described stress tube 4 contacts setting with semi-conductive layer 3, can guarantee the even distribution of terminal electric field, has guaranteed the fail safe that cable uses.
Described shrinkage sleeve pipe 5 is installed on the partial lateral of stress tube 4 and semi-conductive layer 3, and described shrinkage sleeve pipe 5 is gum sleeve, and it has elastic force, can guarantee the sealing that cable is good.
Also be provided with tube connector 6 between the described semi-conductive layer 3.Particularly, described tube connector 6 is arranged between the tail end semi-conductive layer 3 of cable, the described tube connector 6 interior support bars 7 that vertically are provided with.
In the utility model, in the cable installation process, support bar 7 is extracted out, the outside has flexible shrinkage sleeve pipe 5 and just shrinks rapidly and be fastened on the cable body, guaranteed good water-tight performance, guaranteed the reliability of long-time running, whole installation process need not tool using, and is more simple and efficient, safe and reliable.
The beneficial effect of the utility model cold-shrink type cable termination is:
Have good water-tight performance, guaranteed the reliability of long-time running, whole installation process need not tool using, and is more simple and efficient, safe and reliable.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
