Patent number: 7407407Abstract: A connector arrangement for connecting the insulated conductors of a flat cable with an output load includes insulation-piercing contacts that extend upwardly from the horizontal upper surface of the rectangular base member of a connector housing. When a housing cover member is slidably displaced longitudinally of the base member from a first position toward a second position, a first wedge arrangement displaces an actuator plate and a cable support plate downwardly to force the cable into insulation-piercing engagement with the contacts. A locator insulating lug normally extends upwardly from the cable support plate for insertion within an access opening contained in the cable, and between the separated ends defined by an intermediate portion of a conductor that is separated by the access opening. When the cable is uniform and contains no access opening, the lug is displaced by the cable toward an inoperable position relative to the support plate.Type: GrantFiled: December 11, 2007Date of Patent: August 5, 2008Assignee: Weidmüller Interface GmbH & Co. KGInventors: Jens Oesterhaus, Joerg Buschkamp

Patent number: 7408766Abstract: A power supply system for supplying electrical power to at least one load includes a base plate, a support rail and a power supply module fastened to the base plate, at least one bus bar module, and a rail mounting device for mounting the bus bar module on the support rail. The rail mounting device includes conductor members for supplying power from the power supply module to bus bars contained within the bus bar modules, respectively. A first plug has contacts that engage contacts of each of the bus bars of the bus bar module via access slots contained in the cover member thereof, thereby to supply three-phase power to a load such, as a motor, via a heavy-duty power switch and a circuit breaker that are both mounted on the base plate, and associated second and third connecting plugs. Single-phase power is supplied to an auxiliary load, such as an electrical appliance, from two or more bus bars of the bus bar module via a fourth plug.Type: GrantFiled: August 18, 2005Date of Patent: August 5, 2008Assignee: Weidmüller Interface GmbH & Co.

Patent number: 7347716Abstract: A connector arrangement for connecting the insulated conductors of a flat cable with a plurality of tap-off branch conductors includes a plurality of insulation-piercing contacts that extend upwardly from the horizontal upper surface of the rectangular base member of a connector housing. A horizontal actuator plate is arranged in spaced relation above the contacts to define a space for longitudinally receiving the cable. When a housing cover member is initially slidably displaced longitudinally of the base member from an open first position toward a closed second position, a first wedge arrangement displaces the actuator plate downwardly to force the cable into insulation-piercing engagement with the contacts. When the cover member is subsequently displaced to the fully closed second position, a second wedge arrangement clamps the ends of the actuator plate to the cable, thereby to provide the connector contacts with strain relief protection.Type: GrantFiled: May 1, 2007Date of Patent: March 25, 2008Assignee: Weidmüller Interface GmbH & Co.

Publication number: 20080047734Abstract: A cable includes a cable sheath in which are embedded a plurality of insulated conductors at least two of which are helically twisted, the cable being provided with visible markings that indicate where one can electrically engage a selected one of the conductors by an insulation-piercing contact. The cable is formed by arranging a plurality of insulated conductors in a light-transmitting synthetic plastic sheath layer, two or more of the insulated conductors being helically twisted about a longitudinal axis, which cable is optically scanned to determine locations at which contiguous portions of the twisted insulated conductors are superposed orthogonally relative to a reference plane, whereupon markings are formed on the cable sheath layer at locations laterally spaced from the contiguous conductor portions, whereby a selected one of the twisted conductors may be engaged by an insulation-piercing contact.Type: ApplicationFiled: August 11, 2007Publication date: February 28, 2008Inventors: Thomas Hock, Klaus Holterhoff, Jens Oesterhaus, Stephan Fehling

Publication number: 20070293076Abstract: An electrical connector arrangement includes a socket having a central body portion supporting a plurality of female contacts, and a tubular outer portion extending in concentric spaced relation about the body portion to define a groove. A plug component having a cylindrical body portion including a plurality of male contacts includes a tubular end portion that extends axially within the groove to connect the male and female contacts, respectively. A fastening sleeve is rotatably mounted on the plug between the outer surface thereof and the socket outer portion, whereby external screw threads on the sleeve engage internal threads on the socket tubular portion, thereby to fasten together the plug and socket components. In order to reduce the assembly time, the number and length of the screw threads on one of the sleeve and socket components is less than the number and length of the screw threads of the other component.Type: ApplicationFiled: May 31, 2007Publication date: December 20, 2007Inventors: Stefan Fehling, Jens Oesterhaus

Patent number: 7287999Abstract: An electrical connector for insulated conductors includes a housing containing a chamber and having a conductor opening communicating with the chamber, a bus bar mounted in the chamber adjacent the conductor opening, a compression spring mounted in the chamber for biasing the bare end of an insulated conductor inserted into the chamber via the conductor opening into electrical engagement with the bus bar, a retaining device normally retaining the spring in a retracted inoperable condition, and a manually operable release member for releasing the spring to its operable condition. In one embodiment, the release member is connected for sliding movement between releasing and retaining positions, and the housing contains a reset access opening. In a second embodiment, the release member includes a pair of rigid sections joined by a flexible section, the release member being movable between retaining and releasing positions by operating buttons at exposed ends of the sections.Type: GrantFiled: October 20, 2006Date of Patent: October 30, 2007Assignee: Weidmüller Interface GmbH & Co.

Patent number: 7232324Abstract: A plug-in electrical bridge connector includes a pair of parallel bridge contacts that extend through contact openings contained in an insulated bus bar housing arrangement for electrical engagement with bus bars mounted in chambers contained therein, respectively. A locking device is arranged in at least one of the bus bar chambers for automatic locking engagement with the associated bridge contact, thereby to retain the bridge contact in engagement with the associated bus bar. A release device is moveably mounted on the bridge connector body for displacement from a retracted position toward an operable extended position in which the release member unlocks the locking device from the bridge contact, thereby to permit removal of the bridge connector from the bus bar housing arrangement.Type: GrantFiled: November 17, 2005Date of Patent: June 19, 2007Assignee: Weidmüller Interface GmbH & Co.

Patent number: 7170758Abstract: A module connecting arrangement for mounting a module on a support rail includes a horizontal rectangular housing containing a longitudinal chamber, and a bottom surface that contains a recess for transversely receiving the support rail, the recess being in communication with the chamber. A pair of horizontal, superimposed, slidably-connected locking slide members are longitudinally mounted in the chamber. The slide members are spring-biased together toward a locking position in which integral opposed locking lip portions thereon extend below outwardly directed horizontal flange portions of the support rail. A separating member having a non-circular cross-section is rotatably connected with the housing and extends into a gap defined between spaced opposing walls on the slide members, whereby rotation of the separating members produces displacement of the slide members toward released positions relative to the support rail.Type: GrantFiled: June 30, 2006Date of Patent: January 30, 2007Assignee: Weidmuller Interface GmbH & Co.
