Patent ID: 8100708

Claim:
A connection structure for a vehicle, comprising: a first terminal housing with a plurality of first connecting terminals aligned and accommodated therein; a second terminal housing with a plurality of second connecting terminals aligned and accommodated therein; a plurality of isolating plates aligned and accommodated in the first terminal housing, when the first terminal housing and the second terminal housing being mated with each other, the first connecting terminals and the second connecting terminals facing each other to form pairs, respectively, and resulting in a stacked structure of the isolating plates being sandwiched between the pairs of the first connecting terminals and the second connecting terminals, respectively; and a connecting member for pressing the adjacent isolating plate, to thereby collectively fix the first connecting terminals and the second connecting terminals at the contacts therebetween, for electrical connections between the first connecting terminals and the second connecting terminals, respectively, wherein each of the first connecting terminals and each of the second connecting terminals are surface-roughened such that a surface facing to other connecting terminal composing a contact provides a first frictional coefficient, wherein when each of the isolating plates is adjacent to each of the first connecting terminals, each of the isolating plates is integrally fixed to each of the first connecting terminals, and when each of the isolating plates is adjacent to each of the second connecting terminals, each surface of the isolating plates facing to each of the second connecting terminals is surface-roughened to provide a second frictional coefficient, wherein each of the first connecting terminals, each of the second connecting terminals and each of the isolating plates are integrally coupled with each other to suppress movement relative to each other against fretting, when each contact between the first connecting terminals and the second connecting terminals and the isolating plates are pressed by the connecting member.
