Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of multi-door electrode terminal structure for being easy to once weld as shown in Figures 1 to 4, including terminal support 8, DBC plates
6th, chip 3, cross structure 4, fixed sandwich A and special-shaped gate terminal 1.Terminal support 8, DBC plates 6, chip 3 and cross structure 4 are simultaneously
Inside fixed sandwich A；Terminal support 8 and DBC plates 6 are respectively positioned at the two ends of fixed sandwich A；Special-shaped gate terminal 1 is located at
Between terminal support 8 and chip 3, cross structure 4 is located between chip 3 and DBC plates 6.
Chip 3 is using Silica hydrogel apposition as, on DBC plates 6, during temperature change, Silica hydrogel can expand or shrink；
