Abstract
The invention discloses a kind of cold-contraction type indoor terminals.Terminal includes hollow insulation tube; hollow insulation tube one end inner wall is embedded with stress cone; it is equipped with several full skirts outside the hollow insulation tube; further include protective case, the protective case includes ontology made of elastic material, and the ontology is parabola shaped; one end of the ontology is connected with support element; the other end is connected with spring, and the spring part is socketed on the support element, and reinforcing ring is provided on the outside of the hollow insulation tube other end.The cold-contraction type indoor terminal of the present invention is simple in structure, makes insulation tube when shrinking by the way that protective case is arranged, the case where slowly shunk, can preferably be close to cable, hermetically-sealed cable, reduce cracking, improves the service life of terminal.
Description
Technical field
The present invention relates to a kind of cold-contraction type indoor terminals, belong to field of cable technology.
Background technology
Chilling shrink type cable accessory is injected in factory using elastomeric material (there are commonly silicon rubber and EP rubbers)
Sulfidization molding, then through it is expanding, be lined with plastic spiral supporter composition, when in-site installation, by these predilation parts be sleeved on by
Extract the internal plastic spiral item (supporter) supported, the elastomeric material pressure on surface layer after treated cable end piece or joint out
Tightly in cable insulation.Because chilling shrink type cable accessory is to lean on elastic recovery force at normal temperatures, rather than as being heat-shrinked cable accessory
Fiery heat shrink is used, therefore is commonly called as chilling shrink type 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 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, 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 relax as time increases and gradually, 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 not tight phenomenon.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of cold-contraction type indoor terminals.
The present invention is achieved through the following technical solutions：
A kind of cold-contraction type indoor terminal, including hollow insulation tube, hollow insulation tube one end inner wall are embedded with stress cone, institute
It states and is equipped with several full skirts outside hollow insulation tube, further include protective case, the protective case includes ontology made of elastic material, institute
It is parabola shaped to state ontology, and one end of the ontology is connected with support element, and the other end is connected with spring, the spring part set
It is connected on the support element, reinforcing ring is provided on the outside of the hollow insulation tube other end.
A kind of cold-contraction type indoor terminal is arranged on the inner wall at the insulation tube both ends fluted.
A kind of cold-contraction type indoor terminal, the insulation tube include straight length portion and curved section part, the umbrella
Skirt is located at straight length portion, and the stress cone is located at curved section part.
The quantity of a kind of cold-contraction type indoor terminal, the full skirt is five.
A kind of cold-contraction type indoor terminal, the full skirt is provided with protective cover with hollow insulation tube connecting place, described
Protective cover is arc-shaped.
One end of a kind of cold-contraction type indoor terminal, the stress cone is arc.
The advantageous effect that the present invention is reached：
The cold-contraction type indoor terminal of the present invention is simple in structure, makes insulation tube when shrinking by the way that protective case is arranged, is slow
What slow-motion row was shunk, the case where capable of being preferably close to cable, hermetically-sealed cable, reduce cracking, improve the use of terminal
Service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
In figure：1, insulation tube, 11, straight length portion, 12, curved section part, 2, stress cone, 3, full skirt, 4, protective case,
41, ontology, 42, support element, 43, spring, 5, reinforcing ring, 6, groove, 7, protective cover.
Specific implementation mode
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 not intended to limit the protection scope of the present invention.
As shown, a kind of cold-contraction type indoor terminal of the present invention, including hollow insulation tube 1, the hollow insulation tube 1 one
Inner wall is held to be embedded with stress cone 2,1 outside of the hollow insulation tube is equipped with several full skirts 3, further includes protective case 4, the protective case 4
Including ontology 41 made of elastic material, the ontology is parabola shaped, and one end of the ontology 41 is connected with support element 42, separately
One end is connected with spring 43, and 43 part of the spring is socketed on the support element 42, outside 1 other end of hollow insulation tube
Side is provided with reinforcing ring 5.
Further, fluted 6 are arranged on the inner wall at 1 both ends of the insulation tube, squeezes out the air in groove 6, is formed
Negative pressure in groove 6 provides better seal performance.
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
End is arc, can effectively reduce stress concentration phenomenon so that field distribution is also more uniform, so as to improve the jail of connection
By property.
Further, the full skirt 3 is provided with protective cover 7 with 1 connecting place of hollow insulation tube, and the protective cover 7 is circle
Arc.It prevents from generating ponding in full skirt 3 and 1 junction of insulation tube by protective cover 7, avoids creepage phenomenon.
When in use, protective case 4 is placed in one end of insulation tube 1, cable to the terminal of the present invention（It is not shown）Into insulation tube 1
Afterwards, the device of supports insulative pipe 1 is taken out（It is not shown）, at this point, one end of 4 supports insulative pipe 1 of protective case, compressed spring 43 are protected
Sheath 4 takes out out of insulation tube 1, and insulation tube 1 is shunk, and hermetically-sealed cable, reinforcing ring 5 can improve the intensity of 1 end of insulation tube, long
Time, which uses, can also keep preferable leakproofness.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
