Patent number: 8796549Abstract: A bushing is provided for a wire. The bushing includes a polymeric body that extends a length from an end to an opposite end. The body includes a pre-coiled shape wherein the body includes at least one coil defined between the ends. The body is biased to the pre-coiled shape and is flexible such that the body is configured to be at least partially unwound from the pre-coiled shape, against the bias, for wrapping the body around the wire. The body is resiliently unwindable from the pre-coiled shape such that the body is configured to at least partially return to the pre-coiled shape as the body is wrapped around the wire.Type: GrantFiled: February 2, 2011Date of Patent: August 5, 2014Assignee: Tyco Electronics CorporationInventors: Thomas A.

Patent number: 7781684Abstract: A compressible sealing gasket for supporting a cable in a wall opening contained in a housing wall includes a pair of gasket sections each having a planar surface that contains a recess, and at least one integral compressible sealing projection extending from the planar surface adjacent the recess. When the gasket sections are placed in an assembled condition with their planar surfaces in contiguous engagement, the recesses cooperate to define a cable opening for receiving a cable, and the projection is compressed between the gasket sections to seal the space between the gasket sections adjacent the cable opening. Preferably two laterally spaced integral sealing ribs are provided in each recess, which sealing ribs extend transversely completely across the recess and terminate at each end in a sealing projection that extends upwardly from the associated planar surface.Type: GrantFiled: February 27, 2007Date of Patent: August 24, 2010Assignee: Weidmuller Interface GmbH & Co. KGInventors: Peter Stuckmann, Uwe Arlitt, Paulo Russo, John Witt, Günter Lucht, Joachim Bury, Thomas Salomon, Torsten Diekmann, Andreas Wedler, Thomas Pieper

Patent number: 7491084Abstract: A connector system includes a plurality of conductor piercing units supported by a frame for vertical displacement between upper disconnected and lower connected positions relative to a plurality of parallel spaced insulated conductors supported in a horizontal plane by a base plate. The piercing units are displaced between said upper and lower positions by operating disks eccentrically mounted for rotation on a horizontal support shaft that extends between an opposed pair of side walls of the frame. The base plate, frame and piercing unit assembly are arranged in an open-topped support housing that is closed by a cover member or lid. Electrical components may by mounted on the lid for connection with the piercing unit assembly.Type: GrantFiled: October 16, 2007Date of Patent: February 17, 2009Assignee: Weidmüller Interface GmbH & Co.

Patent number: 7407406Abstract: A connector arrangement for tapping off current from a plurality of insulated input conductors includes a rectangular base member having a horizontal planar upper surface provided with a plurality of parallel seats receiving the insulated conductors, a frame mounted on the base member for supporting a plurality of terminal blocks for vertical displacement over the seats, each terminal block including an insulation piercing contact extending downwardly therefrom, and an eccentric disk arrangement for displacing each terminal block relative to the frame member between an elevated position spaced above the associated conductor seat and a lowered position in which the contact penetrates the insulation layer and engages the conductor, thereby to transmit current to an output conductor via the insulation-piercing conductor, a bus bar, and a tap-off terminal.Type: GrantFiled: September 12, 2006Date of Patent: August 5, 2008Assignee: Weidmüller Interface GmbH & Co. KGInventors: Uwe Arlitt, Paulo Russo, Rainer Schulze, John Witt, Günter Lucht, Joachim Bury, Torsten Diekmann, Andreas Wedler, Thomas Salomon, Thomas Pieper

Publication number: 20020069821Abstract: A set for producing labels, having an interactive printing program for an information carrier containing a configurable print image, having labels, which are applied with an adhesive surface to a carrier in an easily removable manner. A transparent cover material forming a laminar layer for covering the applied print image, wherein the cover material is a moisture-repellent plastic foil, is applied to a further carrier with a further adhesive layer in an easily removable manner and has UV protection to prevent the fading of the print image. A lasting, for example over several years, contrast and color brightness, along with great mechanical stability, are achieved because the cover material is of polyester and has a thickness of between 20 and 100 &mgr;m.Type: ApplicationFiled: August 13, 2001Publication date: June 13, 2002Inventors: Thomas Pieper, Jurgen Hermann
