The invention discloses a kind of cold-contraction type outdoor terminal.Terminal includes hollow insulation tube, hollow insulation tube one end inwall is embedded with stress cone, and some full skirts are provided with outside the hollow insulation tube, and multiple grooves are provided with the insulation tube, collets are set in the groove, and the collets are arranged in groove by spring；Spiral helicine support tube is additionally provided with the insulation tube, support member is additionally provided with the support tube, described support member one end is semi-circular groove, radius of the support tube radius less than or equal to semi-circular groove.Cold-contraction type outdoor terminal of the invention extends the service life of support tube, it is ensured that product quality by setting supports support support tube, simultaneously, the tight ness rating of cable and terminal is improve by spring supporting collets, the situation of cracking is reduced, the service life of terminal is extended.
Description
Technical field
The present invention relates to a kind of cold-contraction type outdoor terminal, belong to field of cable technology.
Background technology
Cable accessory is the dress being connected with power transmission line or electrical equipment for connection or cable termination in the middle of cable body
Put.Cold shrinking power cable adjunct is that the tube that silicon rubber is manufactured is carried out into predilation, and support tube, in-site installation are inserted in the middle of product
When remove support tube, the silicone rubber products of predilation automatically reset by the elasticity of rubber, compared to heat-shrink cable accessory need plus
Thermal contraction, this cable accessory that need not be heated is referred to as cold shrinking power cable adjunct.
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 because chilling shrink type cable accessory is predilation, in the case where inner bracing strip is deposited for a long time, it is covered
The radial pressure of pipe can be deformed, or even the situation that adhesion position is separate, and cause it to become waste product.In addition, existing shrinkage
Formula cable accessory is higher using the requirement of solid silicone production performance, the general cable shrinkage annex of quality is often cracking,
Shrink not tight phenomenon.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of cold-contraction type outdoor terminal.
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 inwall are embedded with stress cone, it is described in
Some full skirts are provided with outside empty insulation tube, are provided with the insulation tube and collets is set in multiple grooves, the groove, it is described
Collets are arranged in groove by spring；Spiral helicine support tube is additionally provided with the insulation tube, on the support tube also
Support member is provided with, described support member one end is semi-circular groove, radius of the support tube radius less than or equal to semi-circular groove.
A kind of described cold-contraction type outdoor terminal, the insulation tube includes 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 described cold-contraction type outdoor terminal, the quantity of the full skirt is five.
A kind of described cold-contraction type outdoor terminal, the quantity of the groove and position are corresponding with full skirt.
A kind of described cold-contraction type outdoor terminal, the full skirt is provided with protective cover with hollow insulation tube connecting place, described
Protective cover is circular arc.
A kind of described cold-contraction type outdoor terminal, one end of the stress cone is arc.
The beneficial effect that the present invention is reached：
Cold-contraction type outdoor terminal of the invention extends the service life of support tube by setting supports support support tube, protects
Product quality has been demonstrate,proved, meanwhile, the tight ness rating of cable and terminal is improve by spring supporting collets, reduce 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 examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated, a kind of cold-contraction type outdoor terminal of the invention, including hollow insulation tube 1, the hollow insulation tube 1 one
End inwall is embedded with stress cone 2, is provided with some full skirts 3 outside the hollow insulation tube 1, is provided with the insulation tube 1 multiple recessed
Collets 5 are set in groove 4, the groove 4, and the collets 5 are arranged in groove 4 by spring 6；In the insulation tube 1 also
Spiral helicine support tube 7 is provided with, support member 8 is additionally provided with the support tube 7, the one end of the support member 8 is semi-circular groove
81, radius of the radius of the support tube 7 less than or equal to semi-circular groove 81.Specifically, support member 8 is provided with multiple, is uniformly distributed
On the circumference of support tube 7.
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 is located at curved section part 12.The quantity of the full skirt 3 is five.The quantity of the groove 4
It is corresponding with full skirt 3 with position.One end of the stress cone 2 is arc, can effectively reduce stress concentration phenomenon so that electric field
Distribution is also more uniform, such that it is able to improve the fixing of connection.
Further, the full skirt 3 is provided with protective cover 9 with the connecting place of hollow insulation tube 1, and the protective cover 9 is circle
Arc.Ponding is produced in full skirt 3 and the junction of insulation tube 1, it is to avoid creepage phenomenon when preventing from raining by protective cover 9.
Terminal of the invention when in use, cable（It is not shown）Into in insulation tube 1, the compression spring 6 of support tube 7, insulation
Block 5 is located in groove 4, after, takes out support tube 7, collets 5 in the presence of spring 6, extruded cable, so as to improve tight
Density, support tube 7 is supported by support member 8, prevents support tube 7 from being deformed in prolonged storage, so as to influence product
Quality, when using, support member 8 is taken out.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these improve and deform
Also should be regarded as protection scope of the present invention.
