| An electronic connector which has a plurality of contacts associated in one or more rows in a connector housing, a shape memory spring associated in the connector housing for driving the contacts, the shape memory spring having a beginning shape and transmitting a recovery force to the contacts generated when the shape memory spring reaches a transformation temperature or higher while recovering a stored shape when the shape memory spring reaches the transformation temperature or higher and returning to the beginning shape by the spring force of the contact when the shape memory spring reaches below its transformation temperature. Thus, the electronic connector can mount or dismount contacts to each other without an inserting or removing force or substantially without an inserting or removing force in a simple structure with a reduced number of parts. | ||||||
| 185 | Reinforced connection for a chemical connector and method of constructing therefor | US111200 | 1987-10-22 | US4846709A | 1989-07-11 | Kenzo Kobayashi; Hideto Tachibana |
| A reinforcing fastener for fastening a chemical connector and an electronic circuit includes a substantially cylindrical section shaped element having edges defining an axial slit, wherein the element is formed of an alloy having both superelastic and shape memory properties. The slit is of such a size at a temperature below the Martensite transformation temperature of the alloy that the alloy is superelastically deformed when the slit is maintained at the same size while the alloy is above the Martensite transformation temperature. This results in the chemical connector being fastened to the electronic circuit with a substantially constant force over time. | ||||||

| 191 | Supplementary force heat-recoverable connecting device | US430556 | 1982-09-30 | US4497527A | 1985-02-05 | John K. Cameron |
| A connecting device which 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 tine 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 at least when the substrate is held in the socket. In the martensitic phase of the metal, the tines alone hold the substrate within the socket with sufficient force to provide a physical connection. | ||||||
| 192 | Reusable heat-recoverable connecting device | US436201 | 1982-12-10 | US4462651A | 1984-07-31 | Thomas H. McGaffigan |
| A reusable heat-recoverable connecting device having an annular driver member and a circumferentially split annular spring biasing means inside and generally concentric with the driver member. The spring biasing means normally exerts an outward radial force against the inside surface of the driver member. The driver member is made from a heat-recoverable metal having a martensitic state and an austenitic state. The driver member is expanded radially outward by the spring biasing means when the driver member is in its martensitic state to facilitate insertion of a substrate. The driver member recovers to its non-expanded dimension when it returns to its austenitic state to cause engagement between the spring biasing means and an inserted substrate. | ||||||
| 193 | Heat recoverable composite coupling device with tapered insert | US29212 | 1979-04-12 | US4455041A | 1984-06-19 | Charles L. Martin |
| Described herein are heat recoverable composite couplings comprising an outer, tubular heat-shrinkable sleeve and a hollow insert member adapted to receive plural substrates. The insert member has a tapered surface to allow it to accommodate substrates of different sizes. Recovery of the outer member forces the insert member into secure contact with the substrate forming a union between the substrates. | ||||||
| 194 | Coil connector | US870140 | 1978-01-17 | US4221457A | 1980-09-09 | Leslie J. Allen; Robert L. Hall; Richard J. Penneck |
| Electrical connections to line substrates, such as cables, are made by employing a radially shrinkable coil member which is positioned about the substrate in an expanded form and is then caused or allowed to revert to a smaller radius so that it grips the substrate. In preferred embodiments the coil member is made from a heat-recoverable material or is made from a resilient material which is held in an expanded form by a disburdenable material, e.g. a fusible material such as solder, which is subsequently removed, deformed or destroyed so as to cause connection. The devices are especially suitable for connecting earth leads to the sheaths of mineral insulated cables in the vicinity of terminations and splices thereof. | ||||||

| The disclosure relates to high gain electrical relays which are operable at very low power levels and which, when arranged in a relay system with impedance matching to an energizing power source, are operable at the low power levels used in energizing integrated circuits. The relays utilize nickel-titanium alloy wires which are conditioned and arranged to display sharp, reversible changes in shape and modulus of elasticity as the wires are heated and cooled through a temperature transition range, the alloy wires being disposed, preferably with impedance matching means between the wires and energizing power sources, to be heated through the noted transition temperature range by directing current from such low power sources through the wires, thereby to initiate relay operation. The relay construction provides unusually high gain so that relay operation from such low power sources is effective for regulating operation of various types of components used in electrical apparatus. | ||||||

| Moisture-tight connectors are made from cut lengths of heatshrinkable plastic tubing by shrinking one end of the tubing around a plastic pellet that softens and bonds to it thus forming a seal. An inward constriction is formed in the other end of the tubing by shrinking it over a block that is spaced away from an internal metal sleeve. The constriction is needed to retain a dielectric paste with which the connector is filled.

| Disclosed are actuator devices employing ''''memory material'''' actuator and reset elements that deform from a set shape toward an original shape when subjected to a critical temperature level after having been initially deformed from the original shape into the set shape while at a lower temperature. The actuator and reset elements are mechanically coupled such that temperatureinduced deformation of one into its original shape effects mechanical deformation of the other into its set shape. By selectively and alternately applying heat internally to the actuator and reset elements reversible output motion is provided for a wide variety of output functions.
