The cable assembly includes a strength member having limited elasticity and a plastic jacket formed about the tube and the strength member with the jacket having a flat top surface and a flat bottom surface disposed parallel to the top surface. The tube and the strength member are positioned in the jacket midway between the top and bottom surfaces with the tube and the strength member being spaced and with their respective axes positioned in a plane which is generally parallel to the top and bottom surfaces so that a bend can be formed in the cable by removing a section of the jacket to expose the strength member and the buffer tube. A method of forming and defining the turn using the fiber optic cable assembly is also disclosed.

  • Patent number: 4814549
    Abstract: Layers (12, 14) of a multilayer flexible cable (10) are directed about a bend (22), so that the layers are configured into inner (12) and outer (14) layers. Differently configured spacers (20, 72, 74, 76) are placed between the respective layers at the bend for guiding the outer layer in a path (24) which follows the bend and for guiding the inner layer or layers in a path (26) or paths which is or are generally reversely directed from that of the outer layer.

  • Patent number: 4778948
    Abstract: An arrangement for forming a joint between electrical cables comprises a connector arrangement, e.g. a crimp connector, a fusible block capable of being positioned to enclose the connector and a heat-shrinkable sleeve having a recovery temperature at least C. above the melting point of the fusible block. Preferably the fusible block is formed from a number of interlocking component parts. The arrangement is particularly suitable for forming joints between submarine cables, and may include a tubular shield portion for connecting the shields and shielded cables.

  • Patent number: 4755241
    Abstract: A joint between a mass-impregnated paper insulated cable and a plastic insulated cable is sealed to contain the mass impregnating, oil material by applying a heat-recoverable oil resistant tubing over the exposed paper insulation so as to leave a portion thereof uncovered adjacent the exposed conductor of the cable, applying an oil resistant mastic to said uncovered portion of the insulation and over an adjacent end of said tubing, and applying a further heat-recoverable tubing over the mastic and an adjacent portion of the oil resistant tubing.

  • Patent number: 4745239
    Abstract: A multiple wire joining device is disclosed which includes a generally tubular, deformable, electrically conductive housing having multiple apertures formed in the wall thereof. The apertures are axially spaced apart along the length of the housing and are each adapted to admit a wire therethrough so that it may entend axially along a length of the housing. The spacings between the apertures are sufficient to permit the admittance of a wire into the housing through each of the apertures a sufficient distance to enable the crimping of the housing adjacent each aperture to retain the respective wire therein.

  • Patent number: 4730855
    Abstract: A elbow joint for a permanently mounted explosion-proof pipe which is useful for housing and commercial plant sealed electrical wiring systems that includes a plurality of movable rollers mounted within the inside gradually curved wall portions of the elbow pipe which allows an electrical conductor to be inserted or withdrawn around corners in the piping system quickly and easily. The elbow may be molded or fabricated to include one or more undulations disposed on the inside curved surfaces (along the inside radius of the elbow) to house the rollers and axles therein. Because all interior surfaces and members are permanently sealed from possible explosively hazardous atmosphere, no explosive gases may enter the sealed electrical wiring system through this elbow joint, nor may possible internal electrical arcing escape from the elbow joint into a possibly explosive atmosphere.

  • Patent number: 4696649
    Abstract: A surface mounted grounding connector and method for installing same to the bared shield of a jacketed, shielded cable from which a portion of the jacket has been removed, without severing the shield and reestablishing the moisture protection of the shield. The connector is made up of a contact means placed atop the bared shield and engageable therewith to prevent relative movement of said contact means with respect to said shield. A copper braid is first engaged with said contact means and then wrapped about both said contact means and bared shield to establish a good electrical joint and held in place with a suitable clip.A preformed liquid-tight sealing form has a grounding conductor inserted through a suitable aperture therein and the bared conductor crimped in the crimpable connector attached to the contact means. The form is then moved into position such that its stem fits tightly about the ground conductor and crimpable connector and skirt overlies the contact means and bared shield.
