Abstract: A duplex fiber optic connector assembly enables mating the fibers of a first multifiber cable with like fibers of a second cable or cables with maximum axial alignment of the respective fiber paris. An interconnect member receives cable terminating connectors in opposite sides thereof. Each connector carries the fibers of a respective cable in individual ferrules, each ferrule having limited floating mount within the respective connector. The mating pairs of ferrules are received in opposite ends of receptor members each of which has an axially profiled bore adapted to receive the respective ferrules and a profiled outer surface which allows movement about the geometric center of the receptor so as to axially align the bores of the ferrules received therein. Connectors at each end of a predetermined length of fiber optic cable provide a fiber optic extension cord, analogous to the well-known electrical extension cord, for convenient and efficient interconnection between optical signal-using equipments.

Abstract: A ferrule for electro-optic cables is formed of identical mating halves which, when assembled, provide accurate alignment of the fiber carried thereby. Each ferrule half has a mating surface with a longitudinally extending profiled groove which grips the cable and fiber and centers the fiber with respect to the ferrule. The ferrule halves are preferably permanently bonded together by well known means.

Abstract: A device for pulling fiber optic cable through ducts and conduits comprises an elongated housing having a closed forward end, an open rearward end, and a central bore extending longitudinally therethrough for reception of a pre-terminated fiber optic cable including one or more ferrules terminated in corresponding ferrules which rest within the housing, the forward end being provided with grasping means, and the rearward end being adapted for mounting to a tensile load-bearing portion of the terminated end of the fiber optic cable. In a preferred embodiment, the rearward end is provided with threads for threaded engagement with a receptor nut mounted on the strain relief of a terminated fiber optic cable.

Abstract: A surface mount connector is disclosed for electrically and mechanically interconnecting a mother circuit board with a daughter circuit board. The connector has an elongated housing with an inverted T profile, the cross bar of which engages the mother circuit board and the leg of which has a slot to receive the daughter circuit board. A plurality of terminals are mounted in the connector, each terminal having a first portion lying exposed in the slot and a second portion exposed from the cross bar.

Abstract: A cartridge, cartridge holder and connector system are disclosed formed primarily of two components, namely, an electronic component carrying cartridge and an assembly for receiving the cartridge and interconnecting it as an addition to existing equipment. The holder assembly includes a housing of rigid insulative material defining a cartridge receiving cavity and including means for interconnecting the cartridge to a circuit board or the like. The holder also includes a profiled and polarized entry leading to the cassette cartridge cavity. The cartridge is formed by a pair of mating housing members which enclose a circuit board having a plurality of components mounted thereon. An edge portion of the circuit board is accessible from one end of the cartridge so that when the cartridge is inserted into the cavity of the holder there is an electrical interconnection effected.

Abstract: An improved electrical terminal is disclosed having a mating first end and a conductor engaging second end which is of the insulation piercing type including at least two tine members defining a conductor engaging slot therebetween. At least a portion of the conductor engaging end of the terminal is coated with a layer of insulation. As a terminal, which has the entire second end coated with insulation, is engaged with a conductor, the tines penetrate the conductor insulation and a portion of the insulation coating is stripped from the slot by the interference fit of the conductor in the slot to effect good mechanical and electrical interconnection therebetween. Also, only the tips of the tines can be coated to assure no electrical contact with any conductor they might engage. Thus the subject terminal may be used on shielded cable when it is desired to interconnect with the conductors but not with the shielding.

The apparatus includes means for assuring proper alignment of the cable at the time of application to the connector as well as fixtures to be used at the ends of the harness to cut the cable adjacent the end most connectors. The subject apparatus can be manually or automatically indexed to the proper positions as noted by placing of a connector fixture at the proper locations on a frame assembly.
