Abstract
The utility model discloses the cuprum aluminum wire clamp of a kind of crack resistence, including stacking gradually the base of setting, gland and cushion block, described base, gland and cushion block are fastened by bolts assembly fastening；The wire casing for fixed cable it is provided with between described base and gland；The contact surface that described cushion block contacts with described gland is the arc surface arched upward towards cushion block, technical points is: on described cushion block, the radius of arc surface is less than the radius of arc surface on gland, being consequently formed deformation gap between cushion block and gland, this utility model aims to provide the cuprum aluminum wire clamp of a kind of crack resistence preventing cracking.
Description
Technical field
This utility model relates to a kind of electric armour clamp, more specifically, it relates to a kind of cuprum aluminum wire clamp.
Background technology
Cuprum aluminum wire clamp consumption in gold utensil is big, it is adaptable in overhead power line, the non-holding capacity of wire continues and divides
, support the use protection insulating effect with insulating boot.
In Patent No. CN201320600049.1, the patent of entitled cuprum aluminum wire clamp, disclose a kind of copper aluminum
Parallel groove clamp, including base, gland, cushion block and bolt fastening component, described base, gland and cushion block are sequentially arranged；Described
Base is provided with two the first wire casings arranged in the same direction, and described gland is provided with two the second wire casings arranged in the same direction, two
One wire casing and two the second wire casing one_to_one corresponding are arranged；The contact surface that gland contacts with cushion block is the arc surface of evagination, cushion block
The contact surface contacted with gland is the arc surface of indent；Bolt fastening component includes bolt and the nut matched with bolt；
Cushion block be provided with described bolt is carried out spacing with prevent during turning nut bolt with nut rotate together with spacing
Structure.
When transmission of electricity, wire can produce heat, so that wire and cuprum aluminum wire clamp all can deform upon, thermal expansion occurs
Phenomenon, in above-mentioned prior art, can be because thermal expansion phenomenon causes cushion block to fasten with bolt with gland and cushion block with gland, wire
Mutually extrude between assembly, and then cause the cracking of parallel groove clamp to have an accident.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of crack resistence preventing cracking
Cuprum aluminum wire clamp.
For achieving the above object, this utility model provides following technical scheme: the cuprum aluminum wire clamp of a kind of crack resistence,
Including stacking gradually the base of setting, gland and cushion block, described base, gland and cushion block are fastened by bolts assembly fastening；Institute
State and between base and gland, be provided with the wire casing for fixed cable；The contact surface that described cushion block contacts with described gland is court
The arc surface arched upward to cushion block, wherein: on described cushion block, the radius of arc surface is less than the radius of arc surface, cushion block and pressure on gland
Deformation gap it is consequently formed between lid.
Further, described gland is provided with groove towards the one side of base, and described base is arranged towards the one side of gland
There are projection, described groove and described male cooperation clamping.
Further, it is provided with gap between described groove and described projection.
Further, described groove and described protruding setting are separately positioned on the middle part of gland and base.
Compared with prior art, the utility model has the advantage of: when wire heat production, be provided with between gland and cushion block
The deformation gap of arc, it is possible to leave certain space during to gland thermal expansion, and then prevent cuprum aluminum wire clamp thermal expansion to cause
Cracking；It is provided with gap between described base and described gland, makes thermal diffusivity of the present utility model good, and increase further
Its crack resistence performance.

Detailed description of the invention
Below in conjunction with accompanying drawing, the cuprum aluminum wire clamp embodiment of this utility model crack resistence is described further.
The cuprum aluminum wire clamp of a kind of crack resistence, including base 1, gland 2, cushion block 3 and bolt fastening component 4；The described end
Seat 1 is provided with two the first wire casings arranged in the same direction, and described gland 2 is provided with two the second wire casings arranged in the same direction, two the
One wire casing and two the second wire casing one_to_one corresponding are arranged；Described bolt fastening component 4 includes bolt and the spiral shell matched with bolt
Mother, the contact surface that described cushion block 3 contacts with described gland 2 is all arc surface.
Seeing Figure of description 1, on described cushion block 3, the radian of arc surface is more than the radian of arc surface, described pressure on gland 2
It is provided with deformation gap 5 between lid 2 and cushion block 3；When wire heat production, between gland 2 and cushion block 3, it is provided with deformation gap 5, it is possible to
Leave certain space during to gland 2 thermal expansion, and then prevent the cracking that cuprum aluminum wire clamp thermal expansion causes.
Described gland 2 is provided with groove 7 towards the one side of base 1, and described base 1 is provided with convex towards the one side of gland 2
Playing 6, described groove 7 coordinates clamping with described protruding 6, carries out gland 2 and base 1 preliminary spacing；Described groove 7 is with described
It is provided with gap between protruding 6, makes thermal diffusivity of the present utility model good, and further increase its crack resistence performance.
Preferably, the specification of described cuprum aluminum wire clamp is JB-TL-50-240, i.e. this model is applicable to core cross section and is
50 ~ 240mm, see Fig. 2 and Fig. 3 understand, L be 45mm, B be 60mm, L1 be 71mm.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
