Abstract
The utility model relates to an aluminium-copper double-metal permanent conductive connector. An aluminium-copper binary alloy layer is arranged between a base layer copper plate and a multilayer aluminium plate, and the base layer copper plate, the multilayer aluminium plate, and the aluminium-copper binary alloy layer are integrated. The utility model has the advantages of good electrical conductivity, low energy consumption, high anti-pulling strength, and long service life. The utility model can be made into aluminium-copper double-metal permanent conductive connectors with different specifications and used for the joints of various electrical appliances with different specifications.
Description
The utility model relates to the permanent conductive contact of a kind of al cu bimetal.
The permanent conductive contact of al cu bimetal of the prior art is composited by aluminium sheet and copper coin blast, its composite surface is still a kind of physical state, do not produce chemical change and form binary alloy layer, so its poor electric conductivity, power consumption is high, and tensile strength is low, use after 3～5 months, be subjected to the influence of the nature effect of expanding with heat and contract with cold, obscission easily takes place, directly influence the ordinary production of relevant enterprise and the normal operation of electric equipment.
The purpose of this utility model is to design the permanent conductive contact of a kind of al cu bimetal, adopts unique production process, makes the composite surface of aluminium sheet and copper coin produce chemical change, its electric conductivity is improved, power consumption reduces, and tensile strength improves, and prolong useful life.
Design of the present utility model: the permanent conductive contact of a kind of al cu bimetal, comprise basic unit's copper coin (1) and multiple layer aluminium sheet (2), between basic unit's copper coin (1) and the multiple layer aluminium sheet (2) is aluminum bronze binary alloy layer (3), and basic unit's copper coin (1) is an integral body with aluminum bronze binary alloy layer (3) and multiple layer aluminium sheet (2).
The utility model compared with prior art owing to adopted unique production process, makes the composite surface of aluminium sheet and copper coin produce chemical change and has formed the aluminum bronze binary alloy layer, thereby it conducts electricity very well, and it is low to consume energy, the tensile strength height, long service life generally can reach more than 10 years.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the vertical view of Fig. 1.
In conjunction with Fig. 1,2 embodiment of the present utility model is described.Basic unit selects copper coin (1) for use, under vacuum state, aluminium water is cast in basic unit's copper coin (1) with the method for casting then and go up the multiple layer of formation aluminium sheet (2), key is that the surface of basic unit's copper coin (1) in the process of cast aluminum water has just formed aluminum bronze binary alloy layer (3), aluminum bronze binary alloy layer (3) just is connected to an integral body with basic unit's copper coin (1) and multiple layer aluminium sheet (2) very securely, through the rolling permanent conductive contact of al cu bimetal that just can be made into different size, can be used on the electrical appliance joint of various different sizes again.
Claims (1)
1, the permanent conductive contact of a kind of al cu bimetal, comprise basic unit's copper coin (1) and multiple layer aluminium sheet (2), it is characterized in that: be aluminum bronze binary alloy layer (3) between basic unit's copper coin (1) and the multiple layer aluminium sheet (2), and basic unit's copper coin (1) is an integral body with aluminum bronze binary alloy layer (3) and multiple layer aluminium sheet (2).
