Abstract: An electrical connector for particular use in the data communications industry includes an improved latching mechanism for engagement with a like electrical connector or with an apertured panel of a terminal box or the like. The latching mechanism includes a movable arm pivotally mounted integrally with the housing of the connector. The arm comprises a latch on the front end facing the mating end of the connector. A lever captively supported on the housing includes a cam for engagement in a first position with a cam surface on the back portion of the movable arm to dispose the arm in an inclined relation with the latch located closely adjacent the housing so that the latch may be placed for connection another component. When the lever is slid to a second position, a locking spacer thereon engages the front portion of the arm to move the latch away from the housing and cause engagement of the latch with the other component.

Abstract: A latching apparatus is provided for an electrical connector of the type having a housing including a plurality of electrical contacts therein. The latching apparatus comprises a deflectable arm that is pivotally supported on the connector housing, the pivot being disposed generally between the two ends of the pivotal arm such that both opposed ends of such arm may move relatively toward and away from the connector housing. The front end of the deflectable arm is provided with a latch for attachment to a complementary latch of a mateable electrical connector or the like. A slidable locking bar is captively supported on the housing for movement between a first position and a second position. The locking bar and deflectable arm include cooperative locking means disposed on both sides of the pivot that are operative in the first position to prevent movement of both ends of the latching arm and in the second position to permit free movement of both arm ends.

Abstract: The flat multiconductor cable contains live, neutral and ground conductors lying generally parallel to each other and in side by side, single-plane relation. The live and neutral conductors are sealably surrounded by a relatively hard, polyetherimide material that is substantially free from attack from calcium hydroxide. An outer jacket or casing of polyvinylchloride (PVC) sealably surrounds the polyetherimide layers and contacts the ground conductor. The PVC is substantially free from attack in an alkaline environment. As such, the cable construction provides an enhanced resistance to puncture, particularly in alkaline environments which may be encountered in undercarpet wiring system applications.

Abstract: The flat multiconductor cable contains live, neutral and ground conductors lying generally parallel to each other and in side by side, single-plane relation. The live and neutral conductors are sealably surrounded by a relatively hard, polyetherimide material that is substantially free from attack from calcium hydroxide. An outer jacket or casing of polyvinylchloride (PVC) sealably surrounds the polyetherimide layers and contacts the ground conductor. The PVC is substantially free from attack in an alkaline environment. The polyetherimide layers are extruded over the live and neutral conductors providing a seal therearound and thereby a barrier to moisture. The PVC layer is then extruded over the conductors providing a further seal around the polyetherimide layers.

Abstract: An electrical cable assembly for use in particular with undercarpet wiring systems has a flat multiconductor cable encased in electrical insulation, an insulative film extending lengthwise on the cable and an electrically conductive member overlying the film lengthwise, the conductive member having successive lengthwise extents that are respectively unsecured and secured to the cable. The film is provided with openings therethrough in registry with an exclusive one of the cable conductors through which the conductive member extents are connected to the cable. An electrically conductive shield preferably extends lengthwise with and overlies the conductive member. The shield is selected from material having a hardness greater than that of the conductive member. The material of the conductive member is preferably less cathodic in the electromotive series than the shield material so that in the presence of a corroding medium the shield and not the conductive member will first galvanically corrode.
