    Abstract: A narrow elongated housing is provided constructed of an inner ribbed conduit which is overlaid with two layers of high strength rods. Each layer is contra-helically wrapped with opposing end portions compression secured in a termination chamber. The chamber is formed between a sleeve, which is attached to opposing ends of the conduit, and an outer termination enclosure. With the ends of each layer of rods in the chamber, the enclosure is either held stationary, or slid over the upper layers of rod ends. Concurrently, a wedge is either manually placed in the annular space between the layers and held stationary, or it is forced into the annular space between the layers. Any of the above combination of actions will force the rods against the sleeve and enclosure and frictionally secure them. The wedge may be a malleable metal so that it will cold flow about a portion of the rods. A flexible polymer covering is placed over the assembly to complete the housing.

    Abstract: Armored submarine power cables are designed for laying in waters with varying depths. The cable has an armor which is heavy and strong (steel wires) in shallow water sections. In very deep waters the weight of steel armor is prohibitive so that in these sections the armor is made of synthetic light weight material. The transitions between the two types of armor are made physically concentrated but flexible enough to prevent sharp bends of the cable core as it passes cable laying machinery. The armor joint may be displaced from cable core joints and substantially effectively transfers all longitudinal strain in the cable.

  • Patent number: 4427262
    Abstract: Two cable ends have their cores jointed in a conventional manner. The ends of armor wires, laid up on the cores, are laid with overlap over the core joint. A sleeve with radiused and increased external diameter ends is arranged over the overlap at the core joint. The ends of the armor wires are turned back over the ends of the sleeve such that they come to rest on the outermost surface of the sleeve and are secured thereto by strappings. The outer surface of the sleeve may be coated with an adhesive and gritted to increase the adhesion between the armor wires and the sleeve. The thus spliced armor wires may be provided with a protective winding. The armor splice is such that only a low elongation of the armor wires is possible when longitudinal force is applied to the cable, thus making it particularly suitable for an armored submarine cable including optical fibres.

  • Patent number: 4415223
    Abstract: An interlocking crimp sleeve is disclosed for application to a terminated connector so as to apply an annular crimp securing the cable and particularly the cable shielding thereto. The subject sleeve is formed as an initially flat strip of metal stock having pre-formed opposite ends of an interlocking configuration. The strip is applied to the connector by bending around the electrical cable, engaging the interlocking end configurations and crimping the thus formed substantially cylindrical sleeve to provide the desired clamping and compression of the cable and engagement between the cable shield and connector shield.

    Abstract: A radiation tight connection device for a cable containing a screening mesh or wire which is fixed by clamping. An insert equipped with an insert cone and a collar formed thereat is inserted substantially axially parallel in a conical bore of a screw cap or retaining nut. Provided at the insert cone is an external or outer conical contact surface which corresponds to or is complementary to an inner contact surface of the conical bore of the retaining nut. During assembly the screening wire or mesh is fixed by clamping between both of the contact surfaces. The invention preferably is used in conjunction with plugs or the like.

  • Patent number: 4331374
    Abstract: A cable terminator assembly for a coaxial cable includes a housing having a raided extension affixed thereto for transferring tensile strength from a cable to the housing and braided extension. An inner cylindrical piece is swaged to the housing for holding the braided extension in place. A dielectric clamp with a closure ring, flat locking washer and cap complete the components within the termination. The washer is keyed to the housing and, together with the housing, clamp the stranded cable conductor. The keying prevents turning of the mating components so that the stranded cable conductor will not be damaged. The clamping of the strands makes electrical contact between the strands and the assembly. The dielectric clamp is forced to bite into the dielectric material of the coaxial cable. This provides a firm mechanical hold.

  • Patent number: 4313028
    Abstract: A termination between a lightweight submarine coaxial cable (1) and a tail cable (2) connectible to a submersible repeater includes slip inducing means (8, 14) arranged on the joint (4) and a portion of the submarine cable (1) adjacent the joint such that armour wires arranged on a predetermined length of the submarine cable (1), including the portion, and on the joint (4) will slip during transfer of tensile load from the cable (1) to the repeater housing and not cause compression forces that can damage the joint (4). The length of the armour wires applied directly to the submarine cable sheath is chosen to be sufficient to transfer the tensile load on the cable safely to the repeater housing.

  • Patent number: 4283125
    Abstract: A fiber optic connector is disclosed in which the cable strength member termination comprises inner and outer sleeves surrounding the cable. One of the opposed surfaces of the sleeves is disposed at an angle which opens rearwardly. A clamping ring is disposed between the sleeves. The strength member of the cable is folded back between the angular surface and the clamping ring so that when aa rearward axial load is applied to the cable, the strength member will become more tightly clamped.

  • Patent number: 4280749
    Abstract: An electrical contact for a coaxial cable (3) includes a tubular shell (17, 35) forming an outer contact element (19, 37) and an inner socket (13) or pin (31) type contact element having a pair of laterally spaced resilient fingers (49, 63) housed in a tubular insulator (15, 33). As the tubular insulator (15, 33) is inserted into the tubular shell (17, 35), wedge blocks (85, 107) extending laterally through slots (95, 113) in the walls of the insulator, compress the resilient fingers of the contact element against the center conductor of the cable. The cable shielding (7) is splayed back over a resilient sleeve (115) at one end of a bushing (21) which slides onto the end of the cable. This sleeve is split longitudinally and is resilient such that it may be compressed radially to insert it into the tubular shell (17, 35) where it expands to press the splayed back cable shielding into contact with the tubular shell.

  • Patent number: 4261643
    Abstract: A connector for interconnecting the ends of two optical fiber cables to provide accurate alignment of the optical fibers free of stress from the mechanical linkage of the respective cables. The sheath at the adjoining end of each cable is split in two and separated to expose the optical fiber. The split ends of the sheath are inserted in separate diverging holes in a mounting ferrule while the exposed optical fiber is inserted in a central bore between the diverging holes. The sheath ends are anchored by cementing the ends in the holes. Only the very outer end of the exposed optical fiber is anchored by cement in the ferrule to fix the alignment of the fiber. The rest of the exposed fiber between the anchored outer end and the point at which the sheath is split is bowed slightly to relieve any tension on the fiber. The ends of the cables are joined by mounting the ferrules in a common connector body with the outer ends of the fibers held in abutting axial alignment.
