Description
Technical field
The utility model relates to field of electrical equipment, more specifically, it relates to a kind of cable.
Background technique
Cable generally comprises core and for coating the outer by insulation sleeve of the core.The insulation sleeve of cable has elasticity,
Be made of rubber material, play the protective effect to core, cable when in use directly it is exposed outside, insulation sleeve is most easily trampled
And rupture, cause the breakage of internal core.In order to reinforce the structural strength of insulation sleeve, it will usually increase the thickness of insulation sleeve
Degree, but blocked up insulation sleeve can make the weight of cable promote, and only reinforcement thickness be also unable to reach it is fine to core
Protecting effect, therefore improve insulation sleeve structure, to extend cable service life have a great impact.
Utility model content
In view of the deficienciess of the prior art, being not easy to send out the purpose of this utility model is to provide a kind of structural strength height
It is raw damaged, a kind of cable that the service life is longer.
To achieve the above object, the utility model provides following technical solution:
A kind of cable, including core and insulation sleeve, the core include main line item and six roots of sensation by-pass item, the main line item
On set there are three in the spiral helicine twisted slot of gap distribution, any three by-pass items be located at it is fixed in twisted slot, remaining three
By-pass item is located in the gap that adjacent twisted slot is formed, and two adjacent by-pass items are bonded to each other, and the insulation sleeve includes outer
The buffer layer of layer, the base at middle part and internal waterproof layer, the base are equipped with the pilot hole being arranged in array, in pilot hole
Equipped with buffer spring, one end of the buffer spring and buffer layer are inconsistent, and at least two layers of ball is equipped in the buffer layer
Layer, for every layer of rubber layers of balls at array arrangement, the ball in ball and underlying rubber layers of balls in upper rubber layers of balls is wrong
Position is arranged, and dielectric is filled in the gap between adjacent ball.
The utility model is further arranged to: elastic buffer column is equipped in the buffer spring, the elastic buffer column prolongs
It extends to outside pilot hole, gap is equipped between buffer layer.
The utility model is further arranged to: the thickness of the waterproof layer is greater than the thickness of base, the thickness of the base
For 0.3cm.
By using above-mentioned technical proposal, the twisted mode of main line item and by-pass item is improved, so that the structure of core is more
Step up to gather, be not easy loose.Insulation sleeve is modified to outer layer and buffer layer, and the ball in buffer layer can in time delay pressure
Punching is played the role of protecting set of becoming attached to, is not susceptible to rupture, promotes the service life of cable.

Specific embodiment
The utility model cable embodiment is described further referring to figs. 1 to Fig. 3.
A kind of cable, including core 1 and insulation sleeve 2, the core 1 include main line item 10 and six roots of sensation by-pass item 11, institute
It states and is set on main line item 10 there are three in the spiral helicine twisted slot 100 of gap distribution, any three by-pass items 11 are located at twisted slot 100
Interior fixation, remaining three by-pass items 11 are located in the gap that adjacent twisted slot 100 is formed, two adjacent 11 phases of by-pass item
Mutually fitting, the insulation sleeve 2 include the buffer layer 20 of outer layer, the base 21 at middle part and internal waterproof layer 22, the base 21
It is equipped with the pilot hole 210 being arranged in array, is equipped with buffer spring 211, one end of the buffer spring 211 in pilot hole 210
It is inconsistent with buffer layer 20, be equipped in the buffer layer 20 at least two layers 200 layers of ball, 200 layers of equal Cheng Zhen of every layer of ball
Column are arranged, and the ball 200 in ball 200 and 200 layers of underlying rubber ball on 200 layers of upper rubber ball shifts to install, phase
Dielectric is filled in gap between adjacent ball 200.Elastic buffer column 212, the bullet are equipped in the buffer spring 211
Property bumper post 212 extend to outside pilot hole 210, between buffer layer 20 be equipped with gap.The thickness of the waterproof layer 22 is greater than base
Layer 21 thickness, the base 21 with a thickness of 0.3cm.
Twisted slot 100 is set on main line item 10, three by-pass items 11 are located at fixed in twisted slot 100, remaining three twirls
It closes in the gap of adjacent twisted slot 100, this structure setting can promote the compact-sized degree of core 1, be not susceptible to pine
It dissipates.When cable is under pressure, the ball 200 in buffer layer 20 can play the role of compensator or trimmer pressure.It is oriented on pedestal
Buffer spring 211 in hole 210, can be with 200 compensator or trimmer pressure of auxiliary rubber ball, when the pressure being subject to is excessive, buffer spring 211
Forced contraction plays the role of giving buffer layer 20 support force, waterproof so that buffer layer 20 and elastic buffer column 212 are inconsistent
Layer 22 effectively prevent liquid to enter in core 1, secure to safety.After improvement, it can be mentioned with the service life of Elongated cable wire
Rise work quality.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
