Abstract: A tubular, conductive housing has an axial opening defining an inner surface. An annular, outer lip projects from the inner surface. A centrally located axle within the housing has an annular inner lip opposing the outer lip. Cylinders at either end of the housing engage the axle in the housing and have apertures therein through which wires are inserted and located between the lips. Rotating the cylinders results in the wires being stripped and making electrical contact with the outer lip and conductive housing. Thereby, the wires become electrically interconnected to the conductive housing and to each other.

Abstract: An electrical connector includes opposed matable halves. Each half of the connector includes a rigid outer shell and a one-piece molded elastomeric insert frictionally retained in the respective outer shell. The inserts frictionally retain appropriate electrical terminals. Keys on the inserts cooperate with keyways on the outer shell to ensure proper alignment and polarization. One of the outer shells is mechanically crimped to the cable to provide strain relief and an environmentally sealed connection. One of the inserts is provided with an outwardly extending sealing flange which is tightly urged into contact between the opposed outer shells for environmental sealing. The forward end of one insert defines a peripheral lip which is urged into tight engagement with the mating face of the opposed insert to further contribute to environmental sealing. A right angle adapter molded from an elastomeric material can provide a strain relief transition of the cable through a right angle bend.

Abstract: An electric connector including a housing made of resin and having a plurality of cavities for receiving a plurality of terminals and a terminal retaining member made of resin and having a plurality of holes. When a rear portion of the housing is inserted into an opening formed in a front portion of the terminal retaining member, the housing and terminal retaining member are preliminarily coupled with each other in a first coupling mode in which the holes of the terminal retaining member are aligned with the cavities of the housing. After the terminals having electric wires connected thereto have been inserted into the cavities through the holes, the terminal retaining member is shifted in a direction perpendicular to a direction in which the terminals are inserted and then is further moved toward the housing to attain a second coupling mode. In the second coupling mode the terminals are engaged with portions of the terminal retaining member to prevent the terminals from being removed out of the housing.
