| 123 | Zero insertion force heat-activated retention pin | US10152144 | 2002-05-20 | US06764325B2 | 2004-07-20 | George Arrigotti; Raiyomand Aspandiar; Christopher D. Combs; Tom E. Pearson |
| The present invention relates to apparatus and methods for minimizing open electrical connections between carrier substrates and components connected thereto that occur due to sag in the substrate incurred due to exposure to an increasing heat profile encountered to secure the component to the substrate. A zero insertion force heat activated retention pin expands or bends during the temperature increase, creating an upward force on the printed circuit board. This upward force counters the downward sag forces and enables the carrier substrate to maintain a coplanar relationship with the component being connected. | ||||||
| 124 | Connector apparatus, and associated method, formed of material exhibiting physical-memory characteristics | US09870039 | 2001-05-30 | US06617522B2 | 2003-09-09 | Cristian Tabacutu |
| A connector, and an associated method, for connecting an electrical circuit component to a substrate, such as a printed circuit board. The connector is formed of one of more pin members formed of an electrically-conductive material which exhibits physical-memory characteristics. The pin member 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 upon the substrate. Thereafter, the pin member is heated to beyond a deformation threshold temperature. When at such temperature, the pin member becomes reconfigured into the memory configuration. Through appropriate selection of the memory configuration, heating of the pin member causes connection of the circuit component with the substrate. | ||||||

| 127 | Coupling device with improved thermal interface | US714814 | 1991-06-13 | US5108214A | 1992-04-28 | Malcolm B. Milam |
| A coupling device with a thermal interface occuring along a curved vertical surface is disclosed. One curved surface is on a cold pin extending from a "cold" object and the other curved surface is on a hot pin extending from a "hot" object. The cold pin is fixed and does not move while the hot pin is a flexible member and its movement towards the cold pin will bring the two curved surfaces together forming the coupling and the thermal interface. The actuator member is a shape-memory actuation wire which is attached between the hot pin and the hot object. By properly programming the actuation wire, heat from the hot object will cause the actuation wire to move the hot pin towards the cold pin forming an effective thermal interface. The shape-memory actuation wire is made from a shape-memory-effect alloy such as Nitinol. | ||||||
| 128 | Over-current/over-temperature protection device | US687792 | 1991-04-19 | US5105178A | 1992-04-14 | John F. Krumme |
| An over-current/over-temperature protection device which includes first and second electrical contacts, a separable resistance electrical separable path extending between the contacts, a breaker means and a heater. The heater comprises the separable path. The breaker breaks an electrical connection between at least one of the contacts and the separable path when current above a threshold value passes through the separable path and/or the over-current/over-temperature protection device reaches a threshold temperature. The breaker includes a member of a shape memory alloy which changes shape from a first configuration to a second configuration when the member is heated from a first temperature T.sub.1 to a second temperature T.sub.2. The heater heats the member from the first temperature T.sub.1 to the second temperature T.sub.2 so that the member changes from the first configuration to the second configuration. The over-current/over-temperature protection device can include a spring for changing the member into the first configuration when the member cools from the second temperature T.sub.2 to a temperature T.sub.3 below T.sub.2. The over-current/over-temperature protection device can include a permanent resistance electrical current path having a resistance higher than the separable path. The permanent path minimizes arcing when the electrical connection between the separable path and at least one of the contacts is broken by the breaker. | ||||||
| 129 | Memory metal electrical connector | US324906 | 1989-03-17 | US5098305A | 1992-03-24 | Nicholas J. Krajewski; David J. Johnson; Arthur O. Kunstmann |
| A method and apparatus for interconnecting circuit board assemblies using memory metal wires mechanically inserted into through-plated holes. The invention has its application in the interconnection of stacked circuit board assemblies where kinked memory metal wires are stretched so the wires are substantially straight; inserted into axially aligned through-plated holes of circuit boards; and released so that the memory metal wires reform their original kinked shaped within the through-plated holes, forming an electrical connection between the circuit boards. Memory metal alloys are used in the construction of the kinked memory metal wires to take advantage of the pseudoelastic behavior of the alloys in the austenitic phase below the forming temperature range. | ||||||

| 132 | Operating temperature hybridizing for focal plane arrays | US373117 | 1989-06-29 | US4998688A | 1991-03-12 | Ernest P. Longerich; Saverio A. D'Agostino |
| A detector array assembly which provides for the closing at operating temperature of normally open contacts between individual sensor contact mesas and readout pads of the respective detector and readout chips comprising a detector array assembly. One or more shape memory separator elements are used in conjunction with one or more biasing springs to control the spacing of the contacts. The force of the biasing spring becomes the dominant force as the apparatus is cooled down to near operating temperature, thus moving the chips closer together and establishing reliable electrical connection between the opposed sets of contacts. At temperatures near and above the normal operating temperature of 77 degrees K., the shape memory separator element provides the dominant force and drives the chips apart to open the contacts. | ||||||

| 139 | Thermally responsive electrical connector | US801516 | 1985-11-26 | US4621882A | 1986-11-11 | John F. Krumme |
| A common problem in the art of connecting two electrical components is the providing of a convenient and effective zero insertion force coupling therebetween especially where a plurality of parallel conductors along one component are to be connected with a corresponding plurality along the other. The present apparatus and method address this problem by providing a split tube edge along one of the two electrical components, the split tube including a memory shape material therein. When the split tube is opened, the second electrical component is inserted therein whereupon the split tube can be closed. Conductors along the split tube make contact with corresponding conductors along the second component when the tube is closed. The memory shape material in the split tube acts to either open the split tube or close the split tube when the material reaches a characteristic transition temperature. | ||||||
| 140 | Solderless connector | US688880 | 1985-01-04 | US4575170A | 1986-03-11 | F. Stevenson Gurley |
| A solderless connector is presented wherein a pre-stressed elastomeric element is loaded inside a connector housing chamber or cavity so as to effect electrical contact between circuit devices. In essence, the instant invention employs the restoring forces of a stressed elastomeric material to exert forces in a compressive mode. Thus, in attempting to return to its restored (memory) position, a stretched elastomeric element exerts a pressure inside the connector housing channel which forces the terminal portions of the circuit devices into electrical contact. | ||||||
