Abstract
The utility model relates to a copper-aluminum wiring board, which is widely applied to the fields of power stations, mines, railways, metallurgy and the like. The copper-aluminum wiring board is used for components which connect appliances and electric wires. The copper-aluminum wiring board comprises two wiring board units, wherein main bodies of the wiring board units are made of metal aluminum; and a layer of metal copper layer is arranged on the aluminum-based main body. The copper-aluminum wiring board is characterized in that the surfaces of metal copper layers of the two wiring board units are provided with tooth-shaped structures which are mutually engaged with each other. Therefore, the copper-aluminum wiring board has the advantages of better contact and difficult heating.
Description
Technical field
The utility model relates to a kind of terminal block, and it is a kind of fields such as power station, mine, railway, metallurgy that are widely used in, and is used for the parts that electrical equipment is connected with electric wire.
Background technology
