And extend 1mm；
Originally it is provided with described bimetal disk in described special-shaped pad in vivo；
Described bimetal disk is concentric and the upper circular gasket of circular hole and lower circular gasket are opened in center；In described bimetallic
It is provided with multiply aluminum line nose between pad；
It is disposed with electrical equipment connection sheet and bolt in the lower section of described special-shaped pad body；
On described, circular gasket is sequentially arranged above spring shim and nut, thus constituting multiply aluminum wire and electricity
Anti- short circuit or antiground structure that gas equipment connects.
The feature being applied to the special-shaped pad that multiply aluminum wire is connected with electrical equipment of the present invention lies also in：
Described special-shaped pad body adopts copper material；
The one side of described bimetal disk is copper metal covering, another side is aluminum metal face.
Compared with prior art, the beneficial effects of the present invention is：
1st, special-shaped pad body of the present invention is cylindrical facade one-sided open bottom surface perforated-cup metal object, when multiply aluminum
Wire nose puts into special-shaped pad, and this is internal, and under bolt nut presses, cylindrical facade can effectively prevent multiply aluminum wire
Line nose not do not expand by broken lot, the extruding of line nose opening, and multiply aluminum wire is connected through special-shaped pad with electrical equipment, can achieve insulation
Wire exposed part distance to the ground and leakage distance rise to equipment over the ground, leakage distance, improve grid equipment safety simultaneously
Ensure the reliability that electrical network is powered.
2nd, the petal-shaped anti-slip veins of special-shaped pad base metal thing bottom exterior layer of the present invention, under bolt nut presses, energy
Effectively prevent special-shaped pad body with cap rotation it is ensured that the standardization of the ease for use of pad and construction technology.
3rd, the concentric center of copper aluminum double-level-metal material of the present invention opens the circular gasket of circular hole, realizes copper, aluminum transition consubstantiality.
When multiply aluminum wire and the copper connection sheet of electrical equipment, the circular gasket through Cu-Al bimetal material achieves same material and is connected
Connect, prevent copper, aluminum loose contact cause heating oxidation, or outdoor expand with heat and contract with cold copper aluminum fracture cause phase shortage or ground connection, indoor cabinet
(case) space is little to easily cause short circuit or ground connection etc..
4th, the special-shaped pad that multiply aluminum wire of the present invention is connected with electrical equipment, structure is simple, easy to use, applies model
Enclose wide.

Specific embodiment
In the present embodiment, as shown in figure 1, a kind of be applied to special-shaped pad that multiply aluminum wire is connected with electrical equipment
Composition includes：Special-shaped pad body 5 and double-level-metal pad 3；
As shown in Figure 2, Figure 3 and Figure 4, special-shaped pad body 5 is golden for the cup-shaped of cylindrical facade one-sided open, bottom surface perforate
Belong to thing, cup-shaped metal object bottom exterior layer has petal-shaped anti-slip veins, with special-shaped pad body 5 as parent, through for double-deck gold in it
Belong to the outer diameter D+1mm that pad 3 is daughter, cylindrical facade has 1/6th opening.
As shown in Figure 5 and Figure 6, bimetal disk 3 be copper, aluminum double-level-metal material with one heart and the upper circle of circular hole is opened at center
