Description
Technical field
A kind of cold-contraction type outdoor terminal is the utility model is related to, belongs to field of cable technology.
Background technology
Cable accessory is the dress for being connected among cable body or cable termination is connected with power transmission line or electrical equipment
Put.Cold shrinking power cable adjunct is that the tube of silicon rubber manufacture is carried out into predilation, and support tube, in-site installation are inserted among product
When remove support tube, the silicone rubber products of predilation automatically reset by the elasticity of rubber, needed compared to heat-shrink cable accessory plus
Thermal contraction, this cable accessory that need not be heated are 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 to be 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 of adhesion position separation, cause it to become waste product.In addition, existing shrinkage
Formula cable accessory requires higher using solid silicone production performance, quality in general cable shrinkage annex is often cracking,
Shrink not tight phenomenon.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of cold-contraction type outdoor terminal.
The utility model 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, institute
State and be provided with some full skirts outside hollow insulation tube, multiple grooves are provided with the insulation tube, collets are set in the groove,
The collets are arranged in groove by spring；Spiral helicine support tube, the support tube are additionally provided with the insulation tube
On be additionally provided with support member, described support member one end is semi-circular groove, and the support tube radius is less than or equal to the half of semi-circular groove
Footpath.
A kind of described 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 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 utility model is reached：
Cold-contraction type outdoor terminal of the present utility model extends the use of support tube by setting supports support support tube
In the life-span, product quality is ensure that, meanwhile, the tight ness rating of cable and terminal is improved by spring supporting collets, is reduced out
Situation about splitting, extend the service life of terminal.
