Description
Technical field
The utility model is related to a kind of cable accessory, more particularly to a kind of chilling shrink type cable accessory.
Background technology
Chilling shrink type cable accessory is injected in factory using elastomeric material (conventional has silicon rubber and EP rubbers)
Sulfidization molding, then through expanding, be lined with plastic spiral supporter composition, during in-site installation, by these predilation parts be enclosed within through
Extract the internal plastic spiral bar (supporter) for supporting, the elastomeric material pressure on top layer after cable end piece or joint after process out
Tightly in cable insulation.Because chilling shrink type cable accessory is at normal temperatures by elastic recovery force, rather than as thermal contraction cable accessory
Fiery heat shrink is used, therefore is commonly called as chilling shrink type cable accessory.
There is following advantage in chilling shrink type cable accessory：1. hold cable outer wall using shrinkage stress tightly, and cable is played
The effect of sealing protection；2. range of application is wider, voltage class ranges also relatively wide general application between 0.6KV-110KV；
3. there is small volume, easy to operate, rapid, few without the need for specific purpose tool, scope of application width and product specification；4. applicable surface
Width, a kind of specification are suitable for the cross-section of cable of three kinds of specifications, can be remained to the suitable radial pressure of cable body after installation,
It is tightly combined inner boundary, electrical breakdown will not be produced because of respiration when cable runs；5. installation operation is simple, without
Fire, time saving and energy saving, solve pre-fabricated electric cables annex and shrink the phenomenon that not tight or peace is not entered；5. good airproof performance, damp and hot, high in height
In the environment of salt fog, safety in operation is good；5. chilling shrink type cable accessory is due to the shrinkage stress of itself, can effectively with being protected
The change of the geometry of the cable of shield and change, so as to ensure the sealing of shrinkage annex and outside diameter of cable surface.
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 less, but during this support tube long-time storage, which is subject to the radial pressure of sleeve pipe produce change
Shape, or even there is the situation that adhesion is partially separated, cause which to become waste product.
The utility model patent of 204809822 U of Authorization Notice No. CN is that a kind of good cold-contraction type cable of support effect is attached
Part.It is provided with a support bar, the center line of support bar and the central axis of sleeve pipe on each circle spiral of support tube, many
Root support bar be arranged in parallel along same plane or interlaced certain angle is uniformly arranged.Although the utility model patent improves
Support effect, but many support bars not only arrange difficulty, and also many crisscross support bars also result in one to threading
Fixing sound.
Utility model content
One of purpose of the present utility model is to provide a kind of on the premise of extraction resistance is not increased, long-time storage
Tubular support core rope also will not be damaged easily, and not affect the chilling shrink type cable accessory of threading.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of cold-contraction type cable is attached
Part, including rubber body, is provided with the tubular support core rope formed in ribbon cable spiral winding mode in the rubber tube body, described
Adhesion mutually between each circle spiral of tubular support core rope, the ribbon cable center is provided with one reinforcement.
By above-mentioned technical proposal, the reinforcement in ribbon cable is subject to rubber body to play when extruding in tubular support core rope
The effect of support reinforcing tubular support core rope, it is possible to do not increase extract resistance premise reach chilling shrink type cable accessory long when
Between storage will not light flimsy effect.Even if being provided with reinforcement, inside tubular support core rope, larger space is still left,
Threading will not be impacted.
It is further arranged to：The reinforcement cross section is semicircle.
By above-mentioned technical proposal, the semicircular reinforcement in cross section not only has preferable intensity, and in threading
Electric wire can be made to slip over along the arc surface of reinforcement, be not in the situation that electric wire is reinforced that muscle is blocked.
It is further arranged to：The reinforcement is provided with the inclined-plane with tubular support core reel for rope line into angle.
By above-mentioned technical proposal, during threading, electric wire can be skidded off along the inclined-plane of reinforcement, be not in that electric wire is added
The situation that strong muscle is blocked, the material expended during processing are less.
It is further arranged to：The angle that the inclined-plane and tubular support core reel for rope line are formed is between 30 ° to 60 °.
By above-mentioned technical proposal so that be not in that the excessive contact surface for causing reinforcement and ribbon cable of angle is too little strong
Degree not enough or reinforcement height too high reinforcement when causing ribbon cable to be wound in tubular support core rope situation about damaging.Also will not
There is angle too small, cause the height of reinforcement very short, the support effect played by tubular support core rope is too weak.
It is further arranged to：It is the trapezoidal of longer parallel edges towards ribbon cable side that the reinforcement cross section is.
By above-mentioned technical proposal, trapezoidal compare triangle and parallelogram enabling capabilities higher, and and banding
When rope is connected, total does not have face at an acute angle, more resistant to damage.
It is further arranged to：It is raised that the reinforcement is provided with multiple teasel roots with holes.
By above-mentioned technical proposal, when ribbon cable fracture when extracting out, it may not be necessary to discard whole section of cold-contraction type cable
The ribbon cable of fracture just can be pulled out after putting in the hole hooked in firm teasel root projection with long hook by annex again.
It is further arranged to：The ribbon cable and reinforcement, teasel root projection are integrated.
By above-mentioned technical proposal, whole part is integrally formed and can simplify procedure of processing, reduces difficulty of processing, Er Qieke
So that ribbon cable is more difficult to rupture.
In sum, the beneficial effects of the utility model are：Cold-contraction type cable is reached on the premise of not increasing extraction resistance
Annex long-time storage will not light flimsy effect, nor influence whether threading, just in case ribbon cable ruptures when extracting out
Can continue to use.
