  • Patent number: 5683268
    Abstract: A stackable splice module adapted to engage and mount to additional stackable splice modules to form an electrical connector for pairs of wires, the stackable splice module including an upper portion and a lower portion. A series of indexing teeth are formed along the length of the upper portion, defining wire receiving passages therebetween. Contact elements are mounted within the stackable splice modules, each having an upper end that projects into the teeth of the upper portion of its stackable splice module. The contact elements each include a wire receiving slot aligned with a wire receiving passage of the upper portion and which engages in the insulated wires to establish contact therewith. Lower ends of each contact element project into the lower portions of the splice modules and each include contact slots adapted to engage and receive a contact member of an upper end of a contact element of an additional splice module being stacked thereunder.

  • Patent number: 5309635
    Abstract: A tool (150) of this invention assembles stackable elements (52, 54 and 56) to form a multiple conductor connector (50). A holding bracket assembly (100) is incorporated in the tool (150) to prohibit undesirable movement of the lowermost connector element (52) and to maintain alignment of the various elements of the connector (50) during the connectorization process. In accordance with the present invention, at least one protrusion (112) is manipulated into physical engagement with a side portion of the lowermost connector element (52). The protrusion (112) is spring-loaded and includes a sharp, tapered edge constructed of hardened material which provides a position-securing force to the connector (50) by becoming embedded into the side portion of the lowermost connector element (52). In addition, a second protrusion (110) is aligned opposite each of the sharp protrusions (112) and capable of providing an additional position-securing force to a second side portion of the lowermost connector element (52).
