Connector/nitinol DELTA contact force device

摘要

An electrical connector employs a pin and socket mechanism enclosed by a contact force device. The contact force device has a uniqueness so that after insertion of the pin in the socket with the device at a very low temperature is completed, the device is allowed to return to ambient temperature. The separation force of the pin and socket mechanism is much greater than the insertion force. The contact force device uses nitinol and takes advantage of its transformation temperature in shifting from austenite phase to martensite phase and vice-versa.
