摘要： A one-piece housing for electrical terminals is disclosed, the housing being of the dead-front type and the enclosed terminals being connectable to external electrical circuits through apertures in the dead-front. The housing is generally formed of a dead-front or base member and two side casings, with web hinges joining these members as integral parts and allowing the side casings to pivot into opened and closed positions on the base member. Screw fasteners, located adjacent the ends of the casings remote from the web hinges, secure the casings together and clamp an electrical cord that is wired to the electrical terminals. Access to the enclosed electrical terminals is obtained, for wiring purposes, by opening one or both of the side casings. Locking lugs are formed integral with the side casings and base member to secure the casings to said base member, when the casings are closed, and provide a locking action in directions both longitudinal and lateral of the housing. These locking lugs thus remove both longitudinal and lateral stresses from the web hinges, and even permit continued use of the housing if the web hinges should fracture after repeated flexing.

摘要： A terminal connection which will accept electrical conductors of various sizes and provides oxide breaking, spring loading, and conductor confining and bundling features. A tab or finger on one of the terminal elements presses the conductor regardless of its size toward the other terminal element, and oxide breaking edges on one of the elements break oxide coatings on the conductor while the tab or finger both confines the conductor and forces it toward a mechanical operator such as a screw. Forcing the conductor toward the screw reduces offset loading and permits additional oxide breaking by scraping the conductor with the screw as the screw is rotated to tighten the terminal. In the case of a stranded conductor, the bundling obtained by forcing the conductor toward the screw assures good interstrand electrical contact, so that the electrical resistance at the connection is not significantly different from the resistance of a corresponding solid conductor. In several embodiments, the tab or finger provides the spring loading or spring follow required to maintain good electrical and mechanical characteristics of the connection. In some embodiments, a struck-out leg provides spring loading and the biting action for oxide breaking.

摘要： A grounding electrical adapter for connecting a three-wire plug to a two-wire receptacle connects electrically the grounding blade of the plug to the grounded mounting screw of the receptacle plate, without removing that screw, in a novel manner which not only assures good electrical contact to ground and good mechanical connection to the receptacle but also tends to force a user to make a proper ground connection.

摘要： A one-piece dead-front electrical plug comprises a dead-front member, conductive blades mounted therethrough, and two side covers hingedly connected to the dead-front member by integral web hinges. The side covers pivot between an open position affording access for making wiring connections between a cord and the conductive blades, and a closed position fully enclosing the wiring area. Each side cover has cord clamp teeth which cooperate to grip the cord. The web hinges are protected from longitudinal stress in one embodiment by side cover flanges which are matingly received in notch openings in the dead front member, and in another embodiment by dowel pins protruding from the dead-front member which are matingly received in openings in the side covers. Lateral stress protection of the web hinges is provided by an interengaging flange and groove structure of the side covers and dead-front member. A sealing compound barrier sleeve fits around the wiring connections and tightly against the dead-front member, and is filled with sealing compound to moisture-proof the wiring connections.
摘要翻译： 公开了一种用于电气端子的一体式壳体，该壳体是死角型的，并且封闭端子可通过死角中的孔连接到外部电路。 壳体通常由死前或底部构件和两个侧壳体形成，腹板铰链将这些构件连接成一体，并允许侧壳体枢转到基座构件上的打开和关闭位置。 位于靠近腹板铰链的壳体的端部附近的螺钉紧固件将壳体固定在一起并夹紧连接到电气端子的电线。 为了布线目的，通过打开一个或两个侧壳体，可以获得附近的电气端子。 当壳体关闭时，锁定凸耳与侧壳体和基座构件形成一体，以将壳体固定到所述基座构件，并且在壳体的纵向和横向方向上提供锁定作用。 因此，这些锁定凸耳因此从腹板铰链移除纵向和横向应力，并且如果腹板铰链在反复弯曲之后应该断裂，甚至允许继续使用壳体。
