And extend 1mm；
The bimetal disk is provided with the special-shaped pad body；
The bimetal disk is concentric and the upper circular gasket and lower circular gasket of circular hole are opened in center；In the bimetallic
Multiply aluminum line nose is provided between pad；
Electrical equipment connection sheet and bolt are disposed with below the special-shaped pad body；
Circular gasket is sequentially arranged above spring shim and nut on described, so as to constitute multiply aluminum wire with electricity
The anti-short circuit of gas equipment connection or antiground structure.
It is described in the utility model also to exist the characteristics of be applied to the special-shaped pad that multiply aluminum wire is connected with electrical equipment
In：
The special-shaped pad body uses copper material；
The one side of the bimetal disk is copper metal covering, another side is aluminum metal face.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model special-shaped pad body is cylindrical facade one-sided open bottom surface perforated-cup metal object, works as multiply
Aluminum wire nose is put into special-shaped pad body, and in the case where bolt nut presses, cylindrical facade can effectively prevent multiply aluminum
Wire nose not do not expand by broken lot, the extruding of line nose opening, and multiply aluminum wire is connected with electrical equipment through special-shaped pad, is capable of achieving
Insulated conductor exposed part distance to the ground and leakage distance rise to equipment over the ground, leakage distance, improve grid equipment safety
Property simultaneously ensures the reliability that power network is powered.
2nd, the petal-shaped anti-slip veins of the utility model special-shaped pad base metal thing bottom exterior layer, when bolt nut presses
Under, special-shaped pad body can be effectively prevented with cap rotation, it is ensured that the ease for use of pad and the normalization of construction technology.
3rd, the concentric center of the utility model copper aluminium double-level-metal material opens the circular gasket of circular hole, realizes copper, aluminium transition
Consubstantiality.When multiply aluminum wire and the copper connection sheet of electrical equipment, same material is realized through the circular gasket of Cu-Al bimetal material
Matter is connected, and prevents copper, aluminium loose contact from causing heating to aoxidize, or outdoor expand with heat and contract with cold the fracture of copper aluminium cause phase shortage or ground connection,
Indoor cabinet (case) space is small to easily cause short circuit or ground connection etc..
4th, the special-shaped pad that the utility model multiply aluminum wire is connected with electrical equipment, simple structure is easy to use, should
It is wide with scope.

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 the cup-shaped gold of cylindrical facade one-sided open, bottom surface perforate
Category 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
Category pad 3 is the outer diameter D+1mm of daughter, and cylindrical facade has 1/6th opening.
As shown in Figure 5 and Figure 6, bimetal disk 3 is the upper circle that circular hole is opened at copper, the concentric and center of aluminium double-level-metal material
Shape pad and lower circular gasket.Multiply aluminum line nose 4 is provided between bimetal disk 3；
Electrical equipment connection sheet 6 and bolt 7 are disposed with the lower section of special-shaped pad body 5；
Be sequentially arranged above spring shim 2 and nut 1 in upper circular gasket, thus constitute multiply aluminum wire with it is electric
The anti-short circuit of equipment connection or antiground structure.
In specific implementation, special-shaped pad body 5 uses copper material；
The one side of bimetal disk 3 is copper metal covering, another side is aluminum metal face.
When using, with a specification special-shaped pad, in correspondence insulating plastic-aluminum line connection distribution box as a example by low-voltage wiring terminal：
The line ball screw of low-voltage wiring terminal is first unclamped, special-shaped pad body 5 is inserted in binding post screw rod downwards from screw rod top；So
