Abstract:
Temperature-controlled wire holder (1) made of shape memory material into which a wire (14) under mechanical tension can be clamped in an aperture (2) in the holder, the wire (14) being releasable upon reaching a specific operation temperature, wherein the wire holder (1) comprises a plate made of a TiNi alloy, said plate being pre-treated by being subjected to a mechanical process consisting of rolling to constitute a means to reduce thickness of said plate so that said plate is thin and to increase the austenite triggering temperature of the shape memory alloy to 100Â° C., the wire (14) being clamped within said aperture (2) in the wire holder (1) by compressing the aperture (2), the aperture (2) opening by itself when the wire holder (1) is heated to the specific operation temperature, which is the austenite triggering temperature of the alloy thus releasing the wire.
