Detailed description of the invention
Fig. 1-Fig. 2 is technical solution of the present invention schematic diagram.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
It is somebody's turn to do as Figure 1-Figure 2 in order to solve the above technical problems, the present invention provides a kind of anti-short-circuit electric connecting sheet of direct current
Electric connecting sheet includes: the dystectic first sheet metal A of two panels same material；And one among the first sheet metal of two panels A
Second sheet metal B of piece low melting point；
Above-mentioned three-piece metal piece is linked together by the techniques such as being electroplated or welding, then after carrying out electroplating nickel on surface processing
It is used as electric connecting sheet.
Wherein, the first sheet metal of two panels A thickness is identical, and the second sheet metal B thickness is greater than the first sheet metal A；It is described
The first sheet metal of two panels A respectively includes flat segments and arcuate segment, and the end of the arcuate segment is the respectively company with the second sheet metal B
Meet place, and thicken or multilayer by way of, at binding site, that is, arcuate segment starting position of arcuate segment and flat segments until
End, that is, junction thickness of arcuate segment gradually increases, until identical as the second sheet metal B thickness.
Wherein, the thickness of the second sheet metal B is identical as the first junction sheet metal A, equivalent specified overcurrent energy
Power is identical as the first sheet metal A flat segments part, and fusing-off temperature is much smaller than the first sheet metal A.
Wherein, the sectional area of the first sheet metal A and the second sheet metal B match calculation formula are as follows: ImA × SA=ImB
×SB；
ImA is the rated current-carrying capacity of the first sheet metal A, and ImB is the rated current-carrying capacity of the second sheet metal B, and SA is the first gold medal
Belong to the minimum sectional area of piece A, SB is the sectional area of the second sheet metal B.
Embodiment 1
The present embodiment includes the identical sheet metal A of two panels thickness, and shape as Figure 1-Figure 2 forms arch in junction,
And thicken or multilayer by way of, gradually increased in arcuate segment to junction thickness, it is intermediate until identical as sheet metal B thickness
For piece of metal piece B, thickness is identical as the junction sheet metal A, equivalent specified overcurrent capability and sheet metal A straight portion
Identical, fusing-off temperature is much smaller than sheet metal A, and three-piece metal piece is linked together by the techniques such as being electroplated or welding, then carries out
