い状態を維持することができる。Function The present invention has the above-described configuration, and utilizes the force that causes the connection terminals formed of the shape memory alloy to return to the memorized shape as the temperature rises during operation of the card board. It is possible to maintain a low contact resistance between the card board and the connection terminal. In addition, as the temperature rises during operation of the card board, the card board fixing device made of a shape memory alloy returns to its memorized shape, and by fixing the card board, the contact between the card board and the connection terminal can be maintained for an even longer period of time. It is possible to maintain a low resistance state.
実施例

低い状態を維持することができる。First, the first embodiment shown in FIG. 1 will be described. The card edge connector 11 and connection terminal 12 shown in the drawing are
The shape of the card board 1 is the same as that of the conventional example shown in FIG.
The point is that the connection terminal 12 that clamps 3 is formed of a shape memory alloy. Therefore, even if the connecting terminal 12 is deformed,
As the temperature rises during operation of the card board 13, the connection terminal 12 tries to return to the memorized shape, and the pressure between the contact surface 14 and the card board 13 returns to its original state. Even if insertion and removal are repeated, the contact resistance between the card board 13 and the connection terminals 12 can be maintained in a low state.

As the temperature rises during the operation of 3, it returns to the memorized shape and the card is fixed in the hole 16 formed in the card board 13! By fitting the ends of the terminals 15 and fixing the card board 13, deformation and damage to the connection terminals 12 can be reduced, and the contact resistance between the card board 13 and the connection terminals 12 can be maintained in a low state for a long period of time. .
