Abstract
The invention discloses a kind of silicon rubber cold shrinking power cable adjuncts.Cable accessory includes hollow insulation tube; hollow insulation tube one end inner wall is embedded with stress cone; several full skirts are equipped with outside the hollow insulation tube; further include protective case; the protective case includes the ontology made of elastic material; the ontology is parabola shaped, and the both ends of the ontology are respectively connected with spring, and the spring part is socketed on a support element；Multiple grooves are provided in the insulation tube, collets are set in the groove, the collets are mounted on by elastic component in groove.The cable accessory insulation tube of the present invention is using silicon rubber, and contractive effect is good, by the way that protective case insulation tube is set slowly to be shunk, can be preferably close to cable, hermetically-sealed cable, reduce the situation of cracking when shrinking.The tight ness rating of cable and terminal is improved by elastic component supports insulative block, reduces the situation of cracking, extends the service life of terminal.
Description
Technical field
The present invention relates to a kind of silicon rubber cold shrinking power cable adjuncts, belong 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 object was formed, during in-site installation, after these predilation parts to be sleeved on to cable end piece or joint after treatment
The internal plastic spiral item (support tube) supported of extraction, the elastomeric material on surface layer are 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 being heat-shrinked the fiery heat shrink of cable accessory, therefore are 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 in high-tension
In the state of, and since chilling shrink type cable accessory is predilation, it may go out in the case where inner bracing strip is stored 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 pressing force, so as to it cannot be guaranteed that good interfacial characteristics.In this case, more than cannot ensure cold-contraction type after storage phase
The shrinkage stress of cable accessory, elastic stress can be increased over time and gradually be 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
More demanding, the general cable shrinkage attachment of quality is often cracking, shrinks the phenomenon that not tight.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of silicon rubber cold shrinking power cable adjuncts.
The present invention 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 inner wall is embedded with stress
Cone, the hollow insulation tube outside are equipped with several full skirts, further include protective case, the protective case is included made of elastic material
Ontology, the ontology are parabola shaped, and the both ends of the ontology are respectively connected with spring, and the spring part is socketed in a support
On part；Multiple grooves are provided in the insulation tube, collets are set in the groove, the collets are installed by elastic component
In groove.
A kind of silicon rubber cold shrinking power cable adjunct, the insulation tube include straight length portion and curved section part, institute
It states full skirt and is located at straight length portion, the stress cone is located at curved section part.
A kind of silicon rubber cold shrinking power cable adjunct, the quantity of the full skirt is five.
A kind of silicon rubber cold shrinking power cable adjunct, the surface of the collets is inclined-plane.
A kind of 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 arc-shaped.
A kind of silicon rubber cold shrinking power cable adjunct, one end of the stress cone is arc.
The advantageous effect that the present invention is reached：
The cable accessory insulation tube of the present invention is using silicon rubber, and contractive effect is good, by setting protective case insulation tube
It when shrinking, is slowly shunk, can be preferably close to cable, hermetically-sealed cable, reduce the situation of cracking, improved
The service life of terminal.The tight ness rating of cable and terminal is improved by elastic component supports insulative block, reduces the feelings of cracking
Condition extends the service life of terminal.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
As shown in the figure, a kind of silicon rubber cold shrinking power cable adjunct of the present invention, including hollow insulation tube 1, the hollow insulation
1 one end inner wall of pipe is embedded with stress cone 2, and hollow 1 outside of insulation tube is equipped with several full skirts 3, further includes protective case 4, the guarantor
Sheath 4 includes ontology 41 made of elastic material, and the ontology 41 is parabola shaped, and the both ends of the ontology 41 are respectively connected with
Spring 5,5 part of spring are socketed on a support element 6；Multiple grooves 7, the groove 7 are provided in the insulation tube 1
Interior setting collets 8, the collets 8 are mounted on by elastic component 9 in groove 7.The insulation tube 1 is made of silicon rubber.
Further, the insulation tube 1 includes straight length portion 11 and curved section part 12, and the full skirt 3 is located 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, stress concentration phenomenon can be effectively reduced so that electric field distribution also more uniformly, so as to improve the jail of connection
By property.
Further, the surface of the collets 8 is inclined-plane.
Further, the full skirt 3 is provided with protective cover 10 with hollow 1 connecting place of insulation tube, and the protective cover 10 is
