Abstract: An electrical connector for electrically connecting a hollow bus bar member with an insulated multi-wire or braided conductor inserted axially therein, including a conductive contact screw that is threadably connected within a first opening contained in the bus bar member wall for axial displacement from a retracted position toward a fully penetrating position, thereby to cause a pointed end of the contact screw to successively pierce the adjacent insulation layer, extend diametrically through the multi-wire conductor, pierce the adjacent layer of insulation, and extend into a second opening contained in the adjacent bus bar member wall. The bus bar member may be soldered to a printed circuit board, thereby to connect the multi-wire conductor with conductors on the printed circuit board. Alternatively, plurality of bus bar members may be formed by stamping and bending from a common conductive metal sheet, with the bus bar members being interconnected by integral straps.

Abstract: A connector arrangement includes a flat conductor component having a flat engagement portion, a conductive bus bar component having a flat engagement portion, and a conductive contact screw connecting the conductor and bus bar flat engagement portions in contiguous surface-to-surface electrical engagement. The contact screw has a pointed tip and is axially displaceable from a retracted position normal to and spaced from the flat conductor and bus bar engagement portions toward a connected position in which a pointed end of the screw penetrates or extends through openings in the bus bar and flat conductor engagement portions, and into a bore contained in a housing support surface. The housing support surface supports the flat engagement portions in either a horizontal orientation or a slightly inclined orientation relative to the horizontal upper surface of electrical panel component to which the flat conductor is connected and upon which the housing is mounted.

Abstract: A terminal block connecting apparatus includes first and second support members displaceable from a disengaged condition toward an engaged condition in which corresponding main terminal blocks are brought into electrical engagement, characterized by the provision of first and second test terminal blocks connected with the support members for electrical engagement when the first and second support members are in an intermediate condition between the disengaged and engaged conditions. One of the test terminal blocks is supported by a carrier member for movement relative to the associated support member, whereby the test terminal blocks will remain in electrical engagement during displacement of the support members between the test and connected conditions. A friction retaining arrangement serves to resist displacement of the carrier member relative to its associated support member.
