Interposer, printed board unit, and information processing apparatus

摘要

An interposer includes a first contact terminal pressed against a first fixed terminal for signal transmission; a pair of second contact terminals pressed against second fixed terminals for any one of power supply and grounding, the pair of second contact terminals being disposed with a gap in a pressing direction in which the pair of second contact terminals are pressed against the second fixed terminals, each of the pair of second contact terminals having a larger sectional area than the first contact terminal in a crossing direction that crosses the pressing direction; and a plurality of spring members arranged between the pair of second contact terminals, the plurality of spring members being electro-conductive, having a lower elasticity than the first contact terminal, and pressing the pair of second contact terminals against the second fixed terminals.

1. An interposer comprising:
a first contact terminal pressed against a first fixed terminal for signal transmission; a pair of second contact terminals pressed against second fixed terminals for any one of power supply and grounding, the pair of second contact terminals being disposed with a gap in a pressing direction in which the pair of second contact terminals are pressed against the second fixed terminals, each of the pair of second contact terminals having a larger sectional area than the first contact terminal in a crossing direction that crosses the pressing direction; a plurality of spring members arranged between the pair of second contact terminals, the plurality of spring members being electro-conductive, having a lower elasticity than the first contact terminal, and pressing the pair of second contact terminals against the second fixed terminals; and a substrate in which a through opening where to accommodate the second contact terminals and the spring members is formed, wherein the substrate includes a restricting part that protrudes to an inner side of the through opening and restricts a shift of the second contact terminals in the pressing direction by being in contact with the second contact terminals, and wherein each of the pair of second contact terminals includes a step part to be in contact with the restricting part in a state before an external force is applied from the second fixed terminals to the pair of second contact terminals.
