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 copper-aluminium combination groove preventing cracking
Wire clamp.
For achieving the above object, this utility model provides following technical scheme: a kind of cuprum aluminum wire clamp, the end of including
Seat, gland, balance weight and bolt fastening component；Described base is provided with two the first wire casings be arrangeding in parallel, on described gland
It is provided with two the second wire casings be arrangeding in parallel, two the first wire casings and two the second wire casings just to arranging formation wire casing；Described spiral shell
Bolt fastening assembly includes bolt and the nut matched with bolt, the contact surface that described balance weight contacts with described gland towards
The arc surface that balance weight arches upward, wherein: on described balance weight, the radius of arc surface is less than the radius of arc surface, balance weight on gland
And being consequently formed deformation gap between gland, the one side of described balance weight gland dorsad is provided with stopper slot, the nut card of bolt
It is embedded in this stopper slot.
Further, described line groove hole is applicable to the wire that core cross section is 10 ~ 120mm.
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.
Compared with prior art, the utility model has the advantage of: the flatulence of heat type being set to gland utilizing deformation gap is cold
Contracting provides deformation space, it is to avoid gland overstocks balance weight when distending, causes balance weight by squeeze crack, and then causes wire clamp to loosen nothing
Method clamping cable.And ensure that, when balance weight is squeezed, bolt will not produce skew, protects further by arranging of stopper slot
Demonstrate,prove its fastening effect.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of this utility model a kind of cuprum aluminum wire clamp embodiment.
Reference: 1, base；2, gland；3, balance weight；4, bolt fastening component；5, deformation gap；6, protruding；7, recessed
Groove；8, stopper slot.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model one cuprum aluminum wire clamp embodiment is described further.
A kind of cuprum aluminum wire clamp, including base 1, gland 2, balance weight 3 and bolt fastening component 4；Set on described base 1
Having two the first wire casings be arrangeding in parallel, described gland 2 is provided with two the second wire casings be arrangeding in parallel, two the first wire casings with
Two the second wire casings are just to setting；Described bolt fastening component 4 includes bolt and the nut matched with bolt, described balance weight
3 contact surfaces contacted with described gland 2 are all arc surface, and this arc surface all arches upward towards balance weight 3.
Described first wire casing and the second wire casing are correspondingly formed line groove hole, described line groove hole be applicable to core cross section be 10 ~
The wire of 120mm, being only applicable to core cross section in prior art is 16 ~ 120mm and core cross section is 50 ~ 240mm two kinds
Model, therefore the cross section for less core is inapplicable, causes certain limitation, and this utility model is little for core cross section
In the wire of 16mm, designing the aerial line being applicable to more small dimension, range is bigger.
On described balance weight 3, the radius of arc surface is more than the radius of arc surface on gland 2, so that described gland 2 is with flat
It is provided with deformation gap 5 between weighing apparatus block 3；When wire heat production, it is provided with deformation gap 5 between gland 2 and balance weight 3, it is possible to give
Leave certain space during gland 2 thermal expansion, and then prevent the cracking that cuprum aluminum wire clamp thermal expansion causes, and at balance weight 3
Upper surface on be provided with stopper slot 8, utilize this stopper slot 8 to limit the position of nut in bolt, prevent balance weight 3 by gland 2
Bolt deformation, displacement is caused during extruding.
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.
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
