  • Sealed cable connector
    Patent number: 4810832
    Abstract: A sealed cable connector includes a plug or coupler with a sleeve extending over the cable end and surrounding a strain relief ring, contoured annular seal and a thrust collar. The seal includes an outer ring and an inner ring which are connected with each other by a radial bridge. During assembly, the thrust collar and the strain relief ring cooperate with each other in such a manner that upon axial displacement of the thrust collar toward the strain relief ring by means of a screw plug turned into the sleeve, the bridge becomes sheared off thereby compressing the inner and outer rings within the respective inner and outer spaces between the thrust collar and the strain relief ring while at the same time the thrust collar presses the outer cable conductor against a contacting face of the sleeve.

  • Metal matrix composite and structure using metal matrix composites for electronic applications
    Patent number: 4806704
    Abstract: The invention relates to a metal matrix composite used to support and/or enclose discrete electronic semiconductor devices, monolithic integrated circuits, hybrid circuits, and multi-layer printed wiring boards. The matrices herein disclosed employ aluminum as the matrix with Beta Eucryptite as the additive in a volume percent of up to 60. The preferred range of from 55 to 45 percent by volume of the additive has a coefficient of thermal expansion matching the common semiconductor materials and common ceramics used for electronic enclosures. The composite uses low cost materials, and due to the affinity of the additive to aluminum is easily prepared. The resulting structures have good thermal conductivity and low weight.

  • Assembly for an electrical cable providing strain relief and a water-tight seal
    Patent number: 4789759
    Abstract: A fitting for establishing a seal between an insulated electrical cable (70) and an electrical junction box, where the junction box wall has a threaded bore and a profiled through-hole having a camming surface and shoulder. The fitting includes a threaded nut (50) and a ferrule (30) which has tines (34) extending from a ring portion. The ferrule (30) and the nut (50) are slid over the insulated cable (70) and the assembly is brought in registry with the threaded bore (8) of the junction box. Screwing the nut (50) and ferrule (30) forwardly causes the tines (34) on the ferrule (30) to contact the camming surface (12), forcing the tines (34) into the insulation (72) and the insulation (72) into the shoulder (16), thereby establishing a sealed connection. In a further improvement, the nut (50) has first and second wrench-engaging portions (100, 101) formed integrally therewith.

  • Device for sealing between two metal plates used as electromagnetic field screens
    Patent number: 4788381
    Abstract: A device is provided for achieving a seal between the edge portions of two metal plates which are used as screens against electromagnetic fields, the device including a metallic sealing strip which is intended to be compressed along these edge portions. The sealing strip (1) comprises a helically wound metal element with a cornered cross section, and the edge portion of one metal plate (6) is intended, by engaging against a support (4), to be pressed against the sealing strip (1) both in the cross-sectional and in the longitudinal direction of the strip, so that the turns of the helically wound metal element are twisted in the longitudinal direction of the strip in relation to their original positions. Parts of the cornered sides of the metal element will thus be pressed against said edge portions, which gives good metallic contact.
