Abstract
The invention discloses a kind of cold-contraction type outdoor terminals.Outdoor 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, it further include support tube, the support tube is hollow tubulose, its is closed at both ends, and the at one end of the support tube is provided with stomata, and sealing cover is provided at the stomata；Fluted protrusion corresponding with groove, the snapping coiled that the support tube passes through protrusion and groove are set on the support tube.The inflatable support tube winding of use of the present invention is spiral, in the deflated condition, area increase is adhered between support tube, it improves and is adhered effect, when taking out support tube, support tube is deflated, support tube can be easily taken out, and it can be reused, meanwhile support tube is spiral by groove and raised winding, is completely embedded, even if being adhered position separation, will not deform.
Description
Technical field
The present invention relates to a kind of cold-contraction type outdoor terminals, belong to field of cable technology.
Background technology
Chilling shrink type cable accessory be inject sulfidization molding in factory using elastomeric material, then through it is expanding, be lined with plastics
What spiral support object was constituted, when in-site installation, after these predilation parts are sleeved on 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.
Chilling shrink type cable accessory in use, in order to reduce the extraction resistance of support tube, the spiral slit of support tube
Adhesion intensity is designed to be smaller, but when this support tube long-time storage, will produce change by the radial pressure of casing
Shape, or even there is the case where adhesion is partially separated, cause it to become waste product.And support tube is essentially not reproducible use, makes
At waste.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of cold-contraction type outdoor terminals.
The present invention is achieved through the following technical solutions：
A kind of cold-contraction type outdoor 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 support tube, the support tube is hollow tubulose, closed at both ends,
The at one end of the support tube is provided with stomata, and sealing cover is provided at the stomata；It is arranged on the support tube fluted and recessed
The corresponding protrusion of slot, the snapping coiled that the support tube passes through protrusion and groove.
A kind of cold-contraction type outdoor 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.
A kind of cold-contraction type outdoor terminal, the sealing cover include first part and second part, described second
The diameter divided is more than the diameter of first part, and the first part engages with stomata.
A kind of cold-contraction type outdoor terminal, the insulation tube other end are provided with reinforcing ring.
A kind of cold-contraction type outdoor 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 outdoor terminal, the stress cone is arc.
The advantageous effect that the present invention is reached：
The inflatable support tube winding of use of the present invention is spiral, in the deflated condition, being adhered between support tube
Area increases, and improves and is adhered effect, when taking out support tube, support tube is deflated, can easily take out support tube, and can
It is reused, meanwhile, support tube is spiral by groove and raised winding, is completely embedded, even if being adhered position separation,
It will not deform.

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 outdoor 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 support tube 4, the support tube 4
Closed at both ends for hollow tubulose, the at one end of the support tube 4 is provided with stomata 5, and sealing cover is provided at the stomata 5
6；Fluted 7 and groove 7 corresponding raised 8, the button that the support tube 4 passes through protrusion 8 and groove 7 are set on the support tube 4
Connect coiled.
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.One end of the stress cone 2 is arc, can effectively reduce and answer
Power concentration phenomenon so that field distribution is also more uniform, so as to improve the fixing of connection.
Further, the sealing cover 6 includes first part 61 and second part 62, the diameter of the second part 62
More than the diameter of first part 61, the first part 61 engages with stomata 5.
Further, 1 other end of the insulation tube is provided with reinforcing ring 9.Reinforcing ring 9 improves sealing performance, extends
The service life of cable accessory.
Further, the full skirt 3 is provided with protective cover 10 with 1 connecting place of hollow insulation tube, and the protective cover 10 is
It is arc-shaped.Ponding is generated in full skirt 3 and 1 junction of insulation tube when preventing from raining by protective cover 10, avoids creepage phenomenon.
The cable accessory of the present invention when in use, after 4 coiled of support tube, is inflated, cable（It is not shown）Into exhausted
In edge pipe 1, after, sealing cover 6 is opened, is deflated to support tube 4, take out support tube 4.
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.
