(54) Connector using a shape memory alloy member


(57) Aconnecter has thin sheets (2) of shape memory alloy on a surface of a substrate (1), positioned such that the sheets (2) project over a hole in the substrate. A pin (3) is inserted into the hole with the temperature being such that the sheets (2) are easily deformed. A suitable change oftemperature causes the sheets (2) to attempt to return to their original shape, thereby establishing a good electrical connection between the sheets (2) and the pin (3). Another change of temperature causes the sheets (2) to stop trying to return to their original shape, making it easy to remove the pin (3). This arrangement makes possible a reliable connector which may easily be made small.
