Description
Technical field
A kind of silicon rubber cold shrinking power cable adjunct is the utility model is related to, belongs to field of cable technology.
Background technology
Chilling shrink type cable accessory is to inject sulfidization molding in factory using elastomeric material, then through it is expanding, be lined with plastics
What spiral support thing was formed, during in-site installation, after these predilation parts to be enclosed on to cable end piece or joint after treatment
Extract the plastic spiral bar (support tube) of internal support out, the elastomeric material on top layer is pressed on cable insulation.Because cold-contraction type is electric
Cable fittings are to lean on elastic recovery force at normal temperatures, rather than as thermal contraction cable accessory is with fiery heat shrink, therefore it is commonly called as shrinkage
Formula cable accessory.
Existing chilling shrink type cable accessory is the stress support by internal support bar before being fitted without, and is to be in high-tension
In the state of, and because chilling shrink type cable accessory is predilation, it may go out in the case where inner bracing strip is deposited for a long time
Stay is scattered or silica gel material fatigue shrinks situation not in place, therefore cannot be guaranteed there are enough bullets after on cable
Property thrust, so as to it cannot be guaranteed that good interfacial characteristics.In this case, more than cold-contraction type cannot be ensured after storage phase
The shrinkage stress of cable accessory, its elastic stress can be increased over time and gradually relaxed, therefore chilling shrink type cable accessory
The storage time limit it is shorter, generally half a year was to 2 years.In addition, existing chilling shrink type cable accessory uses solid silicone production performance
It is required that higher, quality in general cable shrinkage annex is often cracking, shrinks not tight phenomenon.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of silicon rubber cold shrinking power cable adjunct.
The utility model is achieved through the following technical solutions：
A kind of silicon rubber cold shrinking power cable adjunct, including hollow insulation tube, hollow insulation tube one end inwall are embedded with stress
Cone, the hollow insulation tube outside are provided with some full skirts, in addition to protective case, and the protective case is included made of elastomeric material
Body, the body are parabola shaped, and the both ends of the body are respectively connected with spring, and the spring part is socketed in a support
On part；Multiple grooves are provided with the insulation tube, collets are set in the groove, the collets are installed by elastic component
In groove.
A kind of described silicon rubber cold shrinking power cable adjunct, the insulation tube include straight length portion and curved section part, institute
State full skirt and be located at straight length portion, the stress cone is located at curved section part.
A kind of described silicon rubber cold shrinking power cable adjunct, the quantity of the full skirt is five.
A kind of described silicon rubber cold shrinking power cable adjunct, the surface of the collets is inclined-plane.
A kind of described silicon rubber cold shrinking power cable adjunct, the full skirt are provided with protective cover with hollow insulation tube connecting place,
The protective cover is circular arc.
A kind of described silicon rubber cold shrinking power cable adjunct, one end of the stress cone is arc.
The beneficial effect that the utility model is reached：
Cable accessory insulation tube of the present utility model uses silicon rubber, and contractive effect is good, by setting protective case exhausted
Edge pipe is slowly shunk, preferably can be close to cable, hermetically-sealed cable, reduce the situation of cracking when shrinking,
Improve the service life of terminal.The tight ness rating of cable and terminal is improved by elastic component supports insulative block, reduces cracking
Situation, extend the service life of terminal.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
As illustrated, a kind of silicon rubber cold shrinking power cable adjunct of the present utility model, including hollow insulation tube 1, it is described hollow
One end inwall of insulation tube 1 is embedded with stress cone 2, and the hollow outside of insulation tube 1 is provided with some full skirts 3, in addition to protective case 4, institute
Stating protective case 4 includes body 41 made of elastomeric material, and the body 41 is parabola shaped, and the both ends of the body 41 connect
Spring 5 is connected to, the part of spring 5 is socketed on a support member 6；Multiple grooves 7 are provided with the insulation tube 1, it is described
Collets 8 are set in groove 7, and the collets 8 are arranged in groove 7 by elastic component 9.The insulation tube 1 uses silicon rubber
Make.
Further, the insulation tube 1 includes straight length portion 11 and curved section part 12, and the full skirt 3 is positioned at straight
Line segment part 11, the stress cone 2 are located at curved section part 12.The quantity of the full skirt 3 is five.The one of the stress cone 2
Hold as arc, can effectively reduce stress concentration phenomenon so that Electric Field Distribution also more uniformly, so as to improve the jail of connection
