ABSTRACT CONNECTING DEVICE A connecting device includes a socket member having at least two tines, the tines having an unstrained configuration from which at least one of the tines can be resiliently deformed away from the other tines to define a socket for receiving and holding a substrate, and a band of heat recoverable metal defining a driver member which in its martensitic phase loosely surrounds the tines so that at least one of the tines can be resiliently deformed outwardly when defining the socket member without deforming the driver member. The driver member when warmed to a temperature at which the metal is in its austenitic phase, recovers inwardly and exerts a supplementary inward force on the tines. In the martensitic phase of the metal, the tines alone hold the substrate within the socket with sufficient force to provide a physical connection.

CONNECTOR APPARATUS, AND ASSOCIATED METHOD, FORMED OF MATERIAL EXHIBITING PHYSICAL-MEMORY CHARACTERISTICS

A connector, and an associated method, for connecting an electrical circuit component (10) to a substrate, such as a printed circuit board. The connector (10) is formed of one of more pin members (14) formed of an electrically-conductive material which exhibits physical-memory characteristics. The pin member (14) is initially configured into a memory configuration and thereafter reconfigured into an alternate reconfiguration. The alternate configuration is selected to facilitate mounting of the circuit component (10) upon the substrate (28). Thereafter, the pin member (14) is heated to beyond a deformation threshold temperature. When at such temperature, the pin member (14) becomes reconfigured into the memory configuration. Through appropriate selection of the memory configuration, heating of the pin member (14) causes connection of the circuit component (10) with the substrate (28).

CRYOGENIC CONNECTION METHOD AND MEANS

Self-locking wire terminal and shape memory wire termination system

A self-locking wire terminal assembly and a shape memory wire termination system includes an electrical terminal constructed with spring legs which provide two opposing points of contact on a mating electrical conductive pin. The points of contact prevent the pin from being removed. The shape memory termination system is formed by electrically coupling a clip assembly to shape memory wire and to an electrical source. In one embodiment, the shape memory wire causes an actuator to activate when the shape memory wire dissipates electrical power. The terminal assemblies may be manufactured by assembling wire with conduction pads onto a continuous reel. The terminal assemblies may be formed from the reel by trimming wire and linkages between the conduction pads.
