Cable accessories generally includes the triangular cone, pyrocondensation branch cover, the stress tube, the insulating tube, the sealed tube, the mark pipe, haplopore rain skirt and three hole rain skirts etc., the triangular cone is installed between the cable conductor, open certain distance with the cable conductor, however, traditional triangular cone exists certain drawback, it can only support the cable of three heart yearns, and the cable not only has three heart yearns, four heart yearns in addition, and traditional triangular cone is difficult to adapt to the cable of four heart yearns, make its practical range narrower, and simultaneously, the triangular cone is when the installation, all be the more firm of installation, mainly receive cable conductor extrusion to cause, if when dismantling the cable, need take off the triangular cone just comparatively difficult, if violently take off, probably cause the cable damage.

Therefore, it is necessary to provide a radiation crosslinking heat shrinkable type cable accessory to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

The technical problem solved by the utility model is to provide a radiation crosslinking thermal shrinkage type cable accessories can realize supporting the cable of three and four heart yearns, has enlarged the application scope of cone, also avoids producing the cable that two kinds of cones come to support three and four heart yearns respectively in production.

In order to solve the technical problem, the utility model provides a radiation crosslinking thermal shrinkage type cable accessories, include: cone and lead screw, a plurality of arc walls have been seted up on the cone, wherein, the arc wall includes main groove, two first vice grooves and the vice groove of three second, main groove and two first vice groove is used for supporting the cable conductor of three heart yearns, main groove and three the vice groove of second is used for supporting the cable conductor of four heart yearns.

Preferably, the cone is of a rubber material.

Preferably, the included angle between each two of the main grooves and the two first auxiliary grooves is 60 degrees, and the main grooves and the three second auxiliary grooves are distributed in an annular array.

Preferably, a threaded sleeve is installed on one side of the cone and is in threaded connection with the screw rod.

Preferably, one end of the screw rod is provided with a pull ring.

Compared with the prior art, the utility model provides a radiation crosslinking heat shrinkage type cable accessories has following beneficial effect:

(1) The device can support cables of three core wires and four core wires, enlarges the application range of the cone, and also avoids the production of two cones to respectively support the cables of three core wires and four core wires.

(2) This device installs the lead screw on threaded sleeve, stimulates the lead screw to can avoid violence to dismantle the comparatively convenient taking off of cone, simultaneously, during the installation cone, also can insert the cone between the cable conductor with lead screw and threaded sleeve connection, handheld lead screw, make the installation of cone comparatively convenient.
