A telephone/CATV adaptor comprises a generally rectangular panel molded from dielectric plastic material for attachment to an associated wall outlet box to provide a closure for the box. The panel carries a modular telephone jack for receiving a mating modular telephone plug and a bulkhead connector to facilitate connection of a coaxial cable through the panel. A plurality of integral pedestals project from the panel and define body portions of a plurality of electrical connectors. Each connector body portion has a blind bore which includes an inner end portion of square cross section. Insulated terminal end portions of a electrical connectors to be electrically connected to each other are each received within an associated corner of the bore inner end portions. A single threaded fastener, sized to cooperate with the bore, has sharp-edged thread convolutions which cut into the walls of the square bore portion and into insulation on the conductors. The sharp-edged convolutions displace the insulation and incise the conductors to establish electrical contact with the conductors.
A connector assembly comprising a connector body having an axially extending bore, at least a portion of said bore having a non-circular cross-section, and means for electrically connecting end portions of a plurality of insulated electrical conductors disposed within said bore portion and extending in the general direction of bore extent and including a single threaded member having a sharp-edged helical thread and sized to cooperate with said bore portion and cut into and displace insulation on the terminal ends of a plurality of individual electrical conductors disposed within said bore portion to establish a plurality of electrical contacts with each of the conductors and anchor the insulated conductors within said bore.
A telephone adaptor comprising a generally rectangular panel sized to form a closure for an electrical outlet box, a modular telephone jack carried by said panel for receiving a mating modular telephone plug, and connecting means on said panel for electrically connecting end portions of a plurality of pairs of insulated electrical conductors and including a plurality of connector assemblies, each of said connector assemblies having a conductor body connected at its inner end to said panel and projecting outwardly from said panel, said connector body having an axially extending bore opening axially outwardly through its outer end, at least a portion of said bore having a non-circular cross-section and a single threaded member having a sharp-edged helical thread and sized to cooperate with said bore to cut into and displace the insulation on the end portions a plurality of individual electrical conductors arranged within said bore inner end portion in generally parallel relation to the bore axis to establish a plurality of electrical contact with each of the conductors and anchor the insulated conductors within the bore when said fastener is driven into said bore between the insulated conductors positioned therein.
A telephone adaptor comprising a generally rectangular panel, means for securing said plate to an associated electrical outlet box to provide a closure for said box, a modular telephone jack carried by said panel and defining a forwardly opening receptacle for receiving a modular telephone plug, and connecting means on said panel for electrically connecting end portions of a plurality of pairs of insulated electrical conductors and including a plurality of connector assemblies, each of said connector assemblies having a connector body integrally connected at its inner end to the rear surface of said panel and projecting outwardly from said rear surface, said connector body having a blind bore opening axially outwardly through its outer end, said bore having an inner end wall and an inner end portion of square cross-section, said bore having a diametrically enlarged outer end portion opening outwardly through said body outer end, said body outer end defining a generally radially disposed bearing surface surrounding said bore, said connector body having four equiangularly spaced and radially disposed slots extending therethrough and communicating with said bore outer end portion, said slots being in registry with the corners of said square inner end portion and opening outwardly through said bearing surface, a post disposed within bore inner end portion and projecting coaxially outwardly from said inner end wall in spaced relation to the walls of said inner end portion, and a single threaded fastener having sharp edged helical thread convolutions and sized to incise the walls of said bore inner end portion and cut through the insulation terminal end portions of a plurality of individual electrical conductors each arranged in an associated corner of said bore inner end portion and extending in a direction parallel to the axis of said bore, said fastener having a diametrically enlarged head defining a generally radially disposed seating surface for seating engagement with said bearing surface when said fastener is driven into said bore.
