The utility model content
The unreasonable part existed for the wire clamp for connecting into subscriber in patent documentation CN2414536Y, the utility model provides a kind of wire clamp for connecting into subscriber rational in infrastructure, and this wire clamp for connecting into subscriber can bear larger pulling force or shearing, can the fracture accident, copper aluminium contact-making surface is large, and resistance value is less, and temperature rise is low.
The technical scheme that realizes the utility model purpose is:
A kind of wire clamp for connecting into subscriber, comprise aluminum base, aluminum gland and the first bolt fastening component;
Described aluminum gland is arranged on an end of described aluminum base by described the first bolt fastening component, be provided with the clamp hole of clamping main cables between described aluminum gland and described aluminum base, the other end of described aluminum base is provided with at least one second bolt fastening component that connects breakout cable;
The side that described aluminum base arranges an end of described the second bolt fastening component is provided with the copper layer, and the first connecting hole that described the second bolt fastening component is set runs through described aluminum base and the setting of described copper layer.
In technique scheme, described copper layer and aluminum gland are located at the not homonymy of described aluminum base.
In technique scheme, the second connecting hole and described the first connecting hole that described the first bolt fastening component is set on described aluminum base are square hole.
In technique scheme, described the first bolt fastening component comprises bolt, balance weight, pad and nut;
The contact-making surface of described aluminum gland and described balance weight is arcwall face.
In technique scheme, the thickness of described copper layer is 0.3mm～2mm.
The utlity model has positive effect: in (1) wire clamp for connecting into subscriber of the present utility model, the copper layer is arranged on a side of aluminum base, so just can bear larger pulling force or shearing, therefore be difficult for the fracture accident, adopt structure of the present utility model, also can increase copper aluminium contact area, resistance value is little, and temperature rise is low; In use, if breakout cable is copper material, breakout cable is connected to the side that aluminum base arranges the copper layer, if breakout cable is aluminium material, breakout cable is connected to the side that aluminum base does not arrange the copper layer.
(2) referring to Fig. 1 and Fig. 2, what show respectively is two kinds of structures described copper layer and aluminum gland being located to the not homonymy of described aluminum base and described copper layer and aluminum gland being located to the same side of described aluminum base, more known, when copper layer and aluminum gland are located to the not homonymy of aluminum base, can guarantee that copper layer and aluminum base have larger contact-making surface, so the conducting property between them is better, and resistance value is lower, more can effectively control temperature rise.
(3) in the utility model, the second connecting hole and described the first connecting hole that described the first bolt fastening component is set on described aluminum base are square hole, so just the bolt in the first bolt fastening component and the second bolt fastening component just can all can be adopted to square neck bolt, thereby facilitate the wiring operation.
The accompanying drawing explanation
A kind of structural representation of the wire clamp for connecting into subscriber that Fig. 1 is the first structure in the utility model;
A kind of structural representation of the wire clamp for connecting into subscriber that Fig. 2 is the second structure in the utility model;
Reference numeral shown in figure is: the 1-aluminum base; 2-aluminum gland; 3-the first bolt fastening component; The 31-bolt; The 32-balance weight; The 33-nut; 4-clamp hole; 5-the second bolt fastening component; 6-copper layer.
Embodiment
A kind of embodiment below in conjunction with Figure of description to wire clamp for connecting into subscriber of the present utility model elaborates:
As shown in Figure 1, a kind of wire clamp for connecting into subscriber, comprise aluminum base 1, aluminum gland 2 and the first bolt fastening component 3; Described aluminum gland 2 is arranged on an end of described aluminum base 1 by described the first bolt fastening component 3, be provided with the clamp hole 4 of clamping main cables between described aluminum gland 2 and described aluminum base 1, the other end of described aluminum base 1 is provided with at least one second bolt fastening component 5 that connects breakout cable; The side that described aluminum base 1 arranges an end of described the second bolt fastening component 5 is provided with copper layer 6, the first connecting hole that described the second bolt fastening component 5 is set runs through described aluminum base 1 and 6 setting of described copper layer, the thickness of described copper layer 6 is 0.3mm～2mm, be preferably 1.2mm, select this thickness better effects if.In the wire clamp for connecting into subscriber of the present embodiment, copper layer 6 is arranged on a side of aluminum base 1, so just can bears larger pulling force or shearing, therefore be difficult for the fracture accident, adopt structure of the present utility model, also can increase copper aluminium contact area, resistance value is little, and temperature rise is low; In use, if breakout cable is copper material, breakout cable is connected to the side that aluminum base 1 arranges copper layer 6, if breakout cable is aluminium material, breakout cable is connected to the side that aluminum base 1 does not arrange copper layer 6.
