  • Connector means for electrical apparatus, particularly plugs
    Patent number: 7347718
    Abstract: A connector arrangement includes a housing containing at least one open-topped chamber in which is mounted a stationary upwardly-directed knife device, and a rectangular carrier member arranged for downward insertion within the chamber, thereby to displace an insulated wire supported by the carrier member toward a position in which the knife device pierces the insulation layer and is brought into electrical engagement with the conductor contained therein. The carrier member includes a top surface containing a slot for receiving the tip of an operating tool that displaces the carrier member downwardly in the chamber, and a side wall containing at least one lug and slot arrangement by means of which the carrier member may be upwardly displaced upon lever-like operation of the tool in cooperation with a side wall of the chamber. Preferably, the housing includes a plurality of the chambers arranged in one or more rows.
