摘要： PROBLEM TO BE SOLVED: To facilitate connecting work for a connector, and prevent the connector or an extension optical cable from being damaged or the something like from being generated. SOLUTION: A connector 2 is fixed to an inside holder 13, and the holder 13 is attached to an outside holder 12 via bearings 14, 15. A rotation-restricting bar 17 extended toward a radial-directional outside is attached to a lower face of the inside holder 13, and a locking pin 18 is provided in a lower face of the outside holder 12. The rotation-restricting bar 17 is engaged with the locking pin 18 to limit a rotation angle of the connector 2 to 360 deg.. A branched optical cable 21 branched from a main optical cable is connected to the connector 2. The branched optical cable 21 has a prescribed length, and a torsion angle in accompaniment to the rotation of the connector 2 is reduced because it is not constricted.

摘要： PURPOSE: To release limitation of installed positions of a branch case to the utmost by reducing remarkably number of joints of pneumatic pipes being components of a pneumatic pipe cable and reducing number of fused connecting positions of optical fiber cores in the case of building up an optical network so as to remarkably reduce the trouble and the cost of the work and decreasing even the shape of the branch case to the utmost. CONSTITUTION: A single pneumatic pipe cable 4 is installed from a start to an end of an optical network without any joint on its way and required numbers of pneumatic pipes 64 being components of the cable 4 for branching are cut off at required positions of the pneumatic pipe cable 4. Each branching pipe 9 is connected to each cut-off pneumatic pipe 6 and an optical fiber unit is connected from the pneumatic pipe 6 at the start of the pneumatic pipe cable 4 through the pneumatic pipe 9 for branching.

摘要： PURPOSE: To provide a satisfactory outer appearance form by axially forming a notch on a constricted part formed between a suspension wire and a cable body which are integrally covered with a resin, and forming a nearly circular through-hole on both ends of the notch so as to communicate with them. CONSTITUTION: A slightly axially long cable body 3 is arranged in parallel to a suspension wire 2 in the slightly twisted state, and the both are integrally covered with a coating resin 4 to form an aerial cable 1. On a constricted part 5 formed on the resin thin part between the suspension wire 2 and the cable body 3, a notch 6 is formed in the cable axial direction in the state hardly having a width by means of a cutting blade such as cutter. Nearly circular through-holes 7 communicating with the notch 6 are formed with a relatively small aperture on both the ends by a punch. Since these are precisely formed, no chip is left. In such a cable 1, the cable body 3 is suspended in a catenary form to the suspension wire 2, and the notch 6 is deformed in arch to form an air slit 8.

摘要： PURPOSE:To provide the extrusion straightening device which does not generate a twist in the neck part of an integral sheath of the self-supporting type cable provided with a sag. CONSTITUTION:The self-supporting type cable 1 is made freely rotatable around the traveling axis O of its supporting wire 6 and a rotary disk is provided within a cooling water tank on the downstream side of a cross head. A pair of rollers 23, 24 are mounted to this rotary disk. A first passage 41 having a circular section, a second passage 42 having a circular section and a slit- shaped third passage 43 are formed to a pair of these rollers 23, 24. A supporting wire coating part 45 coating the supporting wire 6 passes the first passage 41, a core coating part 46 for coating a cable core 5 passes the second passage 42 and the neck part 7 passes the third passage 43.

摘要： PURPOSE:To provide a slit forming method for an overhead sagging cable whose neck parts can be left to every prescribed position in longitudinal direction even if there is difference among the reversely rotating pitches in longitudinal direction of the cable. CONSTITUTION:A cable main body 5 which has a similar cross-section shape to that of a gourd and is produced by connecting winding cable core parts 3 at neck parts and in which the cable core parts 3 swing and rotate reversely within a prescribed range of reversely rotating angle on the axial center of a linear supporting parts 2 in the cross-section as the cable goes further in the longitudinal direction is sent in the longitudinal direction and slits are formed in the neck parts of the cable main body 5 by a cutter 10. The reversely rotating angle of the center of the reversely rotating pitch P in the longitudinal direction of the cable core parts 3 is detected in the upper stream side of the cutter 10 and from the time when the detected reversely rotating angle becomes the same as the reversely rotating angle of a cable core part 3 before the cutter 10, slit formation at the neck parts is temporarily stopped to leave neck parts for every prescribed reversely rotating angle.
