The contact-making surface that described gland contacts with balance weight is the arcwall face of evagination, the arcwall face that the contact-making surface that corresponding described balance weight contacts with described gland is indent;
Described bolt fastening component comprises bolt and the nut matching with bolt;
Described balance weight is provided with described bolt is carried out to the spacing position limiting structure to prevent that bolt together rotates with nut in turning the process of nut.
In technique scheme, described position limiting structure is arranged on the stopper slot on described balance weight for connecting, and the head of described bolt is limited in described stopper slot.
In technique scheme, described bolt fastening component also comprises plain washer and the elastic washer being arranged near described nut one end.
In technique scheme, described base is aluminum alloy base, and described gland is aluminium alloy gland;
Equal compound copper layer that is provided with in corresponding described first wire casing and described second wire casing on described base and gland.
In technique scheme, the thickness of described copper layer is 0.5mm～1.5mm.
In technique scheme, the quantity of described bolt fastening component is two.
The utlity model has positive effect:
(1), in the utility model, described balance weight is provided with described bolt is carried out to the spacing position limiting structure to prevent that bolt together rotates with nut in turning the process of nut.Because position limiting structure has carried out spacingly to bolt, in the process of fastening bolt fastening assembly, bolt can together not rotate with nut, makes installment work convenient, has reduced the danger of work high above the ground; The balance weight that is provided with position limiting structure can mate the cuprum aluminum wire clamp of various different structures.
(2) in the utility model, described position limiting structure is arranged on the stopper slot on described balance weight for connecting, and the head of described bolt is limited in described stopper slot; Stopper slot in said structure is to connect to be arranged on balance weight, adopts this structure to be easier to processing.
(3) in the utility model, described base is aluminum alloy base, and described gland is aluminium alloy gland; Equal compound copper layer that is provided with in corresponding first wire casing and second wire casing on described base and gland; By adopting this structure to use copper material amount seldom, major part is aluminum alloy materials, the weight of product is alleviated greatly, and also saved production cost.
(4) in the utility model, the quantity of described bolt fastening component is two, adopts two fastening better effects if of bolt fastening component.

Embodiment
Below in conjunction with Figure of description, a kind of embodiment of cuprum aluminum wire clamp of the present utility model is elaborated:
As shown in Figure 2, a kind of cuprum aluminum wire clamp, comprises base 1, gland 2, balance weight 3 and bolt fastening component 4, and described base 1, gland 2 and balance weight 3 sequentially arrange; Described base 1 is provided with two the first wire casings that arrange in the same way, and described gland 2 is provided with two the second wire casings that arrange in the same way, two the first wire casings and the corresponding setting one by one of two the second wire casings; The arcwall face that the contact-making surface that described gland 2 contacts with balance weight 3 is evagination, the arcwall face that the contact-making surface that corresponding described balance weight 3 contacts with described gland 2 is indent; Described bolt fastening component 4 comprises bolt 41 and the nut 42 matching with bolt 41; Described balance weight 3 is provided with described bolt 41 is carried out to the spacing position limiting structure to prevent that bolt 41 together rotates with nut 42 in the process that turns nut 42.Because position limiting structure has carried out spacingly to bolt 41, in the process of fastening bolt fastening assembly 4, bolt 41 can together not rotate with nut 42, makes installment work convenient, has reduced the danger of work high above the ground yet; The balance weight 3 that is provided with position limiting structure can mate the cuprum aluminum wire clamp of various different structures, and need not change the original structure of cuprum aluminum wire clamp.
