Abstract
The utility model relates to a power plug and a latch thereof. The power plug comprises a main body and the latch extending from the main body. The latch possesses an inner core and an outer layer; the inner core is made of aluminium, and the external layer is prepared by copper material and is covered on the outer surface of the inner core. The above latch of the power plug employs copper and aluminium to perform composition, combines the advantages of copper and aluminum conductors, possesses the advantages of low price, good conductive performance, light weight, high intensity, easy welding, etc., effectively makes up the disadvantages of pure copper and pure aluminum conductors in engineering application, is in favor of the comprehensive utilization of non ferrous metal resource and can greatly reduce the cost of power plug products.
Description
Technical field
The utility model relates to conductive connecting device, relates in particular to a kind of attaching plug and latch thereof.
Background technology
At present, the latch of existing attaching plug mostly is pure copper material greatly, because copper price continuous rise, this attaching plug is the cost height not only, and is subjected to the restriction of china natural resources shortage; And the conductivity of pure aluminum material and intensity are relatively poor.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of cost lower and electric conductivity and the good attaching plug of intensity.
Technical problem to be solved in the utility model is, provides a kind of cost lower and electric conductivity and the good attaching plug latch of intensity.
Attaching plug of the present utility model is realized that like this it comprises main body and the latch that goes out from Subject Extension, and latch has inner core and skin, and inner core is an aluminium, and skin is made by copper material, and it is coated on the outer surface of inner core.
Further, described latch is column, and its cross section is circular, square or rectangular.
Attaching plug latch of the present utility model is realized that like this it has inner core and skin, and inner core is an aluminium, and skin is made by copper material, and it is coated on the outer surface of inner core.
Further, described latch is column, and its cross section is circular, square or rectangular.
Compared with prior art, the latch of the utility model attaching plug adopts copper and aluminium to carry out compound, it combines the advantage of copper, aluminium conductor, have price lower, conduct electricity very well, in light weight, characteristics such as intensity is high, easy welding, effectively remedied the shortcoming that fine copper and fine aluminium conductor are used on engineering, help the comprehensive utilization of nonferrous metal resource, can significantly reduce the cost of attaching plug product.
