The use environment of different cables differs greatly, and cable is usually provided with protective case to improve the safety that cable uses, existing skill
The technical solution of a variety of cable protective sleeves is disclosed in art.
Publication No. CN2884632, the Chinese patent that publication date is on March 28th, 2007 disclose a kind of clamping butt
Cable protecting sleeve, which is arranged to two split impartial semicircles for protection sleeve pipe, in the arc of two halves circular portion
End is equipped with bayonet unit, bayonet unit by a semicircle one end curved end recessed Button Block and positioning surface and another half
The convex buckle head and positioning surface composition of the associated curved end of circle, the split tube wall interface of full circle are that the connection of two semicircles is fixed
Plane is directed at two semicircles in use, buckling another semicircle of corresponding buckle by cable laying in a semicircle
The positioning surface that is connected, fasten the convex buckle head being connected and recessed Button Block both completed clamping butt-opening power cable sheath to cable
It is laid with.Since the structure of the cable protective sleeve two sides is different, also needs to be arranged two sets of production moulds, in addition also need accurately to count
It calculates, guarantees that two side lengths are identical, in order to avoid cause to waste.
Publication No. CN202454989U, publication date are that the Chinese patent on the 26th of September in 2012 discloses a kind of separate
Formula power cable sheath pipe is made of upper tube half and lower tube half through engaging portion fastening, and engaging portion is plugged on snapping by snapping public affairs rib
It is constituted in female groove, wherein the smooth outer surface of snapping public affairs rib, snapping female groove inner surface is equipped with zigzag protrusion, and zigzag protrusion is disconnected
It is continuous to be arranged on the inner surface of snapping female groove.The art solutions solve snapping intensity between snapping public affairs rib and snapping female groove
Insufficient problem does not propose solution to the other problems in cable use.
But in the practical application of cable protective sleeve, phase mutual friction between cable and fitting be easy to cause the mill of protective case
Damage.Under long-term hanging operating condition, when cable gentle breeze is swung, the long-term friction between protective case and cable also can be right
Cable surface damages.In addition, cable protective sleeve is generally macromolecule material, in long-term use, due to macromolecule material
The factors such as material aging, fatigue are easy to produce deformation, gap occur so as to cause protective case splicing position, influence protecting effect.
Utility model content
In order to solve the problems in the existing technology, technical solution provided by the utility model is: a kind of wear-resisting electric power
Cable protective sleeve is formed by left half side and the right side is half side, is right half side after left half side 180 ° of the rotation of central axis along its length.
It is left it is half side with it is right it is half side connect using plug-in type buckle, left half side upper end is grafting protrusion, and the half side lower end in a left side is recessed for grafting
Slot, left half side grafting protrusion and right half side grafting groove, left half side grafting groove and right half side grafting protrusion buckle
Connection.During installation, appropriate dedicated cementing agent can be coated in grafting groove, on the one hand improved grafting and snapped connection intensity, separately
On the one hand prevent protective case outside liquid from penetrating into internal.
A kind of power cable protective case sets gradually protective case liner, protective case intermediate buffer layer, protective case from inside to outside
Wear resistant outer layer.Protective case liner and wear resistant outer layer are fixed on the inner and outer surfaces of protective case intermediate buffer layer by hot melt.
Preferably, the protective case wear resistant outer layer is aryl fiber cloth.
Preferably, the protective case intermediate buffer layer is polyester type polyurethane material.
Preferably, the protective case liner is methyl vinyl silicone rubber.
Preferably, aryl fiber cloth used in the protective case wear resistant outer layer is plain cloth.
Compared with prior art, the utility model has the advantage that (1) passes through plain weave aryl fiber cloth is solid through heating
It is scheduled on the outer surface of protective case intermediate buffer layer, conducting wire is not only effectively prevented and is damaged when contacting friction with fitting,
But also significantly improve the tensile strength of cable；(2) pass through setting protective case wear resistant outer layer, the aging shape of protective case entirety
Variability is lower, it is therefore prevented that because protective case splicing position gap occurs, influences the problem of protective case protecting effect caused by aging deformation；
(3) inner surface of protective case intermediate buffer layer is fixed on by heating laying-in in methyl vinyl silicone rubber, it is also ensured that protect
Sheath will not wear conducting wire under longtime running gentle breeze swing state, ensure the safe operation of transmission line of electricity；(4) due to protection
The structure on two sides of set is identical, therefore is not required at left and right sides of difference in production, in addition, the left and right sides structure of protective case is simple,
Grafting is convenient, and dedicated cementing agent is in addition cooperated to use, can get it is good snap connection intensity, while can also prevent outside protective case
Portion's liquid penetrates into internal.
