  • Patent number: 5713766
    Abstract: Electric barrier terminal strips which enable conversion from a screw type format of wiring terminals to a higher pitch row of female connectors. To compensate for the larger spacings between the screw type format of screw wiring terminals, the screw type wiring terminals can be arranged in first and second rows, either staggered or not, one on each side of the row of female connectors. Individual female connectors in the row are connected alternatively with a screw wiring terminal from the first row and a screw wiring terminal from the second row. The single row of female connectors can be arranged in a EURO format housed within a EURO style shroud, for connection to a row of conductor pins in a EURO style header. Alternatively, the single row of female connectors can be provided near a flat bottom surface of the barrier terminal strip, for connection to a row of conductor pins projecting from a printed wiring or circuit board.

    Abstract: A circuit assembly is made by overmolding, with an electrically insulating material, a unitary framework of electrically conductive material forming coplanar conductors which are connected to each other by an integral structural member. The overmolded material secures the conductors relative to each other and enables portions of the structural member to be severed, electrically isolating the conductors from each other. The overmolded material also positions electrical components having leads that are electrically connected to the conductors. Ends of the conductors are formed into terminals which extend out of a hinge formed in the overmolded material. The hinge enables the terminals to be oriented in a different plane than the conductors.

The conductor connecting section comprises terminals arranged in two adjacent rows that are offset to provide a compact zig-zag arrangement. The terminals are separated by upstanding walls that form slots on the sides of the connector for receiving ring-tongue terminals that are clamped to the terminals by screws. To ensure a sufficient insulation between adjacent terminals, the walls must be made sufficiently long. In order to enable a compact juxtaposed assembly of connectors to a backpanel, the separating walls are slanted thereby forming a zig-zag outer profile of the connector sides such that sides of adjacent connectors interengage.

A bore 40 formed through the block from one sidewall to an opposed sidewall is adapted to receive the high voltage, high current wire which is clamped against the block by a set screw 44 received in a threaded bore 42 which communicates with the bore extending between the sidewalls. Another threaded member 60 is received through a bore 58 in the circuit board disposed between the two slots and into a threaded bore 62 in the bottom of the block disposed on one side of the circuit board with the head 62 of the threaded member engaging the high voltage, high current trace 22 or 14 on the opposite side of the circuit board. A layer of solder 68 is then placed over the head and onto the trace.

  • Patent number: 5266058
    Abstract: The present invention relates to a terminal connecting device which simplifies and facilitates achieving the proper alignment between a male-threaded portion of a terminal screw and a female-threaded hole of a stationary terminal, and moreover, which assures that a fastening operation is easily performed. The terminal connecting device includes a terminal screw guiding member adapted to be displaced along a side wall, the terminal screw being engaged with the terminal screw guiding member. The terminal screw or the terminal screw guiding member may also be supported by the resilient action of an elastic member of which one end is supported by the side wall. Alternatively, the terminal screws may be housed in a housing which is slidably attached to the side wall and which may be locked in place with the aid of a resilient member and latching apparatus.

  • Patent number: 5192234
    Abstract: A terminal for electrical equipement in which a wire is held in a wire-insertion duct between a clamping element of a strip and another clamping element constituting the bottom of a cage that surrounds the strips. The wire is held by drive from a screw with the screw being screwed into the cage and pressing obliquely against the clamping element of the strip on the opposite side thereof to its side which faces the clamping element of the cage. The clamping element of the cage is extended by an extension constituting a wire-guide which projects from the cage into the wire insertion duct parallel to the screw axis and which obstructs the duct to guide any wire disposed obliquely in the wire-insertion duct.

  • Patent number: 5176540
    Abstract: A distributor strip is composed of an underpart housing and of a contact part housing mechanically joined thereto. The contact part housing contains the contact parts of the contacts belonging to the line leads in corresponding receptacle chambers. The mechanical joining of the housing parts occurs with the assistance of a plurality of cache elements arranged in a row. Guide elements that engage at the cooperating shape-matched to one another upon joining at present at the end-face limiting wall surface. An accurate guidance of the contact part housing to be introduced and, therefore, a secured position of this housing relative to the cache elements are therefore effected when the two housing parts are joined, for example given the utilization of what are referred to as channel and spring elements. This pre-centering also secures the adhesion of the two housing parts, particularly when such cache elements are present exclusively at one elongate side.
