Abstract: A testing and cut-off device for a telephone or computer line to connect two incoming strands to two outgoing strands, comprises a testing well inside which are located a first couple of terminals corresponding to the two incoming strands and a second couple of terminals corresponding to the two outgoing strands, and a pivotal cover for closing the well. These two couples of terminals are insulated from one another, when the cover is open. Each terminal is accessible from the outside by a testing plug. The device further comprises electrical contacts in the cover for interconnecting the terminals when the cover is closed. Said interconnection means in the pivotal cover also comprise means for galvanically linking the latter with an additional electrical component outside the well when the cover is closed. The additional component may be within or outside the cover. If outside it may be connected by wires joined to insulation displacement contacts attached to the cover.
Abstract: A testing and cut-off device, intended to be interposed on a bifilar telephone or computer-related line in order to connect two incoming strands to two outgoing strands, comprises a testing well inside which are located, on the one hand, a couple of free terminals (32, 33) corresponding to the two incoming strands and, on the other hand, a couple of free terminals (41, 42) corresponding to the two outgoing strands, and a cover (59) for closing the well. These two couples of terminals (32, 33, 41, 42) are electrically insulated with respect to one another, when the cover (59) is open, and each terminal (32, 33, 41, 42) then becoming selectively accessible from the outside by a respective testing plug. The testing and cut-off device further comprises means incorporating electrical contacts contained in the cover for effecting the interconnection of these couples of terminals in two's when the cover (59) is closed on the well.
Abstract: A watertight inlet device for inserting a cable containing optical fibers into a chamber or a container, e.g. into a splice box. The device includes a metal solepiece for securing the strength members of the optical cable, and which plugs into and fixes to a tubular sealing body equipped with an external O-ring gasket and having its rear portion shaped to form a sealing stuffing box on the outer sheath of the cable. The rear of the nut of the stuffing box receives a clamp for retaining the cable. Once the device has been fitted, the resulting assembly is inserted into the inlet passageway until it abuts against a shoulder in the passageway. Then only the head of the securing solepiece and a groove in the body project inside the container, the groove then receiving a key or fork for retaining the assembly.

Abstract: An optical fiber organizer and a box for receiving it. The inlets for the optical cables project side-by-side in row abreast from the same short side of the box bottom. The organizer includes a pedestal which receives, in nested manner, stackable modules for holding cassettes. The pedestal is made of a plastics material and has an outside shape that is rounded. A transit empty space is provided before the pedestal for the purpose of passing the fibers, and a storage empty space is provided after the pedestal for the purpose of storing standby fibers.
Abstract: A connection device is particularly suited for connection of the two strands of a telephone or computer-related line in a sub-distribution terminal block. The device includes an insulating base with a cavity formed therein in which I.D.C. contacts are secured for receiving the strands. Opposite each I.D.C. contact is secured a blade for cutting the scrap of wire. A pusher, comprising a master screw for movement and lateral slots for introduction of the wires, is telescopically associated with this base. The cutting blade is provided so that, after the cut, the free end of the cut wire is disengaged from this blade. The assembly further forms a reservoir of sealing gel, or other like product, which is virtually closed.

Abstract: A device for mounting a cable in a cable protection sleeve that makes use of a disc (101;102). Among the disc's various structural features, the disc has a front face or surface, that is, one which is intended to face towards the outside of the sleeve. The front face of the disc includes at least one cable securing mechanism (140;141) which, in turn, includes a cable securing flange (141, 4, 4) enclosed in a housing (120; 20, 20; 20, 23, 20) formed on the front face of the disc. When the cable securing flange is received in the housing, a cable secured relative to the disc by the flange resists outwardly directed tensile forces, as well as torsion and bending moments applied to the cable.
Abstract: The device includes channels into which sealing gel or grease can be injected from an orifice in the housing in the cavity which receives an electrical wire or plug. The channels are structured to reduce or avoid the formation of voids within the corresponding structure. A related method includes the step of injecting the sealing gel or grease via a channel and into a cavity which receives a line or wire therein.
Abstract: The connecting device includes a drum (3) and two means (4) for securing wire bundles of the cables to be connected. Said securing means (4) are generally symmetrically positioned on either side of the drum (3), substantially coaxially therewith, and the drum (3) carries members for positioning the connection means at uniformly distributed locations adjacent its periphery.
Abstract: This invention relates to a module, made in one and the same piece, intended for interconnecting two monopair lines, typically two telephone or computer-related lines. It brings together in one module an alignment of three functional zones: a first functional zone of connection of the two "large wires" by I.D.C. and pusher with screw, a second functional zone comprising a test and possibly protection chamber closed by a cut-off lid, and a third functional zone comprising two I.D.C.'s for connection of the "small wires" and a connection pusher.
Abstract: This invention relates to a device for connecting a sheathed electric wire in an insulation-displacing contact with the aid of a pivoting connection pusher. When the rotary pusher is opened after the wire is connected, a "semi-hard" point is passed by reason of a cam which pushes an elastic switch element, then the pusher is maintained in its position of maximum opening by a hollow in the cam, while the line connection then remains cut off by the effect of this cam.
Abstract: This invention relates to a method and device for reliably and positively connecting electric wires in receiving insulation-displacing slots. The pivoting connection pusher is closed by a locking catch borne by an elastic tongue and cooperating with a fixed closure stop. Locking is produced after passage of a hard point and provokes a clearly audible click which indicates to the installer that the insulation-displacing connection of the wire is then positively effected.
Abstract: This invention relates to a terminal block for interconnection of telephone or computer-related lines having a rate of rejection of near-end crosstalk complying with very strict standards. The extended portion of each insulation-displacing contact has a bevel on an edge which is next to the adjacent pair increasing the distance therebetween and reducing the crosstalk.
Abstract: This invention relates to a socket of the "modular-Jack" type, provided to receive cables arriving from very varied directions. It is associated with a connecting pusher which is totally symmetrical with respect to a transverse plane. Jaws fixed on the socket cooperate with shapes on the rear of the pusher in a order to grip it and introduce it by force, with a lever effect, in this receiving part. The receiving part has insulation displacement contact, which are intended to engage strands of the cable received.
Abstract: This invention relates to a device for rapidly connecting a user cable on a conductor cable, particularly on ships. It is composed of two interfitting half-boxes each receiving one of the two cables to be interconnected, and which imprison an intermediate plate fitted with double points for interconnection by piercing of the insulation, these points being fixed on this plate in which they are integrated in advance when it is constructed in the factory.
