Abstract: A printed circuit board receptacle connector that terminates itself in its characteristic impedance when a mating plug is disengaged therefrom.

Abstract: A rotatable electrical plug and power cord for mating with a conventional electrical outlet comprises a housing first portion and a housing second portion rotatably coupled to the housing first portion. The housing first portion carries first and second electrically conductive outlet prongs extend from the housing first portion a sufficient distance to permit the prongs to engage into an electrical outlet. The housing second portion is connected to the proximal end of a power cord such that the power cord can rotate relative to the prongs. The power has a pair of electrical conductors extending between its proximal and distal ends. A flexible conductor means electrically interconnects the power cord conductors with the respective prongs and permits the housing first portion to rotate relative to the housing second portion without imparting forces on the power cord conductors.

Abstract: Opposed plate portions are spaced a predetermined distance from each other to form a press-connecting blade, and deformation prevention piece portions of an L-shaped horizontal cross-section are provided beneath the plate portions to support the same from the lower side. With this construction, there is achieved a press-connecting portion of a press-connecting terminal, in which the plate portions of are prevented from being deformed away from each other when a wire is press-fitted into the press-connecting blade.

Abstract: There is provided a patch panel having a plurality of rows of wire termination connectors mounted to one side of a circuit board. A plurality of jacks, which are mounted to the other side of the circuit board, extend through the patch panel face plate. A cable tie bar is rotatably attached to the patch panel by a pair of hinges so that the cable tie bar may be rotated to various positions with respect to the wire termination connectors providing unimpaired access to all of the connectors.

Abstract: The object of the present invention is to provide an electrical connector in which a mechanism for preventing the incorrect insertion of terminals is part of the housing lances so that the incorrect insertion of terminals is prevented. Housing lances 6 are formed in the housing 2 of an electrical connector 1. The housing lances 6 have an inclined surface 8 which protrudes into cavities 4, and recesses 20, which accommodate projections 76 used to prevent the incorrect insertion of terminals 70, are formed in the inclined surfaces 8. Stop surfaces 22 which are contacted by the projections 76 are formed in the front portions of the recesses 20. As a result, further insertion of the terminals 70 is prevented so that incorrect insertion is prevented.
