Patent number: 8790128Abstract: Systems and methods are disclosed relating to an electric distributor device for connecting to at least one cable, comprising a guide device, a connection part, and a coupling nut for screwing onto the connection part. According to one illustrative implementation, the guide device may have a cable holder part for holding several cable end regions, each having at least one conductor and a conductor guide part for guiding the conductors by means of conductor guiding structures, wherein the insulation displacement connector device has a number of crimping clamps corresponding to the number of cables and each of the connectors is electrically connected to an assigned connection element. Here, for example, when the coupling nut which overlaps the guide device, is screwed onto the connection part, the conductor insulation of the conductors that run in the guide device may be severed by the crimping clamps.Type: GrantFiled: June 6, 2011Date of Patent: July 29, 2014Assignee: Phoenix Contact GmbH & Co. KGInventor: Jens Andresen

Patent number: 8790129Abstract: A system and method is provided for assembling and/or customizing a connector. Preferred embodiments of the present invention operate in accordance with a connector that includes a plurality of removable contacts, and a connector body that can be customized to mate with a corresponding, and similarly configured connector. In one embodiment of the present invention, a contact is connected to a wire and inserted into an aperture in a retainer. The retainer is then inserted into a connector body, thereby resulting in an increase in friction between the retainer and the contact, and a backshell is attached to the connector body. At least one key is placed in at least one keyway on the connector body, resulting in a user-programmable connector. The connector is then mated with a corresponding connector that is similarly configured. The connectors are then secured using either a latch or lanyard mechanism.Type: GrantFiled: January 14, 2013Date of Patent: July 29, 2014Assignee: Deutsch Engineered Connecting Devices, Inc.Inventors: Alex Robert Rengifo, Troy Tom

Patent number: 8790132Abstract: A fixing structure of a connector includes a housing and a rear holder fixing the housing to a casing by screws. The rear holder has a base plate opposing the casing. First through holes are formed on the base plate so as to correspond to second openings for leading out conductive parts of the female terminals respectively. Terminal holding members are respectively provided at the first through holes for contacting the female terminals respectively. The screws are inserted respectively through second through holes which are arranged so as to deviate to one side with respect to a center of gravity of a region in which the first through holes are formed. Elasticity of one of the terminal holding members which is disposed at a first position facing at least one of the second through holes in a peripheral part of the region are smaller than elasticity of another one of the terminal holding members which is disposed at a position except for the first position.Type: GrantFiled: January 14, 2011Date of Patent: July 29, 2014Assignee: Yazaki CorporationInventors: Motohisa Kashiyama, Masanobu Oishi
