Patent number: 11133617Abstract: An electrical plug connection has two main contacts—one plug-in contact and one socket contact configured to mate when the contacts are connected. In the connected state, the contacts contact each other at a main contact point. An auxiliary contact is associated with one of the two main contacts to form an assembly and plug unit. The auxiliary contact is designed as a spring contact which contacts the other main contact in the region of a second contact point. When the two plug-in contacts are disconnected, the auxiliary contact is connected in an electrically non-conductive manner to the main contact with which it is associated. In the mating or connected state where the two main contacts contact each other, the auxiliary contact contacts the other main contact with which it is not associated to form an assembly and plug unit at an auxiliary contact point for measuring the power loss across the plug connection.Type: GrantFiled: July 17, 2018Date of Patent: September 28, 2021Inventors: Michael Herrmann, Jürgen Ziemke

Patent number: 8771004Abstract: A spring terminal for connecting the bare end of a conductor with a bus bar, including an insulated housing containing a chamber defined by a pair of planar parallel spaced vertical side walls, and an orthogonally connected vertical end wall. Mounted in the chamber are a vertical bus bar adjacent the end wall, and a U-shaped clamping spring that biases toward clamped electrical engagement with the bus bar the bare end of a vertical conductor that is inserted downwardly into the chamber. The clamping spring includes a stationary lower leg portion fixed to the housing, a pivotable body portion, and an upper clamping leg portion that engages the conductor, a locking arrangement serving to lock the body portion to the housing when the spring is in the clamping condition.Type: GrantFiled: June 27, 2011Date of Patent: July 8, 2014Assignee: Weidmueller Interface GmbH & Co.

Patent number: 7326073Abstract: A locking device attaches to a first end of a plug-supporting housing a telecommunications plug having a cable that extends through a longitudinal bore contained in the housing. The locking device includes at least one locking plate having a first end portion connected with the housing, and a second end portion containing a projection for engaging a corresponding retaining surface, thereby to retrain the plug within a first plug-receiving chamber contained within a first end of the housing. In a first embodiment, the locking plate directly retains in the first chamber either the plug, or a hollow adapter frame that contains the plug. In a second embodiment, an adapter body containing a second plug-receiving chamber is fastened to the housing first end, and a pair of locking plates lock within the second chamber either the plug, or an adapter frame that contains the plug.Type: GrantFiled: December 19, 2006Date of Patent: February 5, 2008Assignee: Weidmüller Interface GmbH & Co.

Patent number: 7063557Abstract: An electrical connector includes a connector body that contains an open-topped chamber in which is mounted a stationary, upwardly-directed insulation-severing electrical contact, together with an operating member for displacing an insulated conductor laterally downwardly in the chamber. The operating member includes a flexible intermediate portion that permits the leading end of the operating member to be introduced initially downwardly into the chamber, and subsequently to be diverted upwardly relative to the connector body by a guide surface arranged at the bottom of the chamber. As the leading and trailing ends of the operating member approach their final positions relative to the connector body, the insulation layer of the conductor is severed by knife edges on the stationary contact, and the conductor is brought into electrical engagement contact with the contact.Type: GrantFiled: April 11, 2005Date of Patent: June 20, 2006Assignee: Weidmüller Interface GmbH & Co.
