Description

  The present invention relates to an apparatus for manufacturing a shielded cable including a laminated shield tape and a metal shield.

  2. Description of the Related Art Conventionally, a winding rotary type twisting machine has been known as a manufacturing apparatus that can perform a horizontal shield or tape winding on the outer periphery of a cable core. For example, as shown in FIG. 7, the cable core 10 delivered from the supply bobbin 3 attached to the rotating supply device 100 is wound around the winding bobbin 4 attached to the rotating winding device 200. At this time, the cable core 10 travels while rotating between the rotating supply device 100 and the winding device 200 and is wound around the winding bobbin 4 at a constant speed.

  When a horizontally wound shield is provided on the outer periphery of the cable core 10 that travels while rotating, the plurality of shield strands 9 supplied from the shield supply 5 are aligned along the outer periphery of the cable core 10 that travels while rotating. Thus, the shield wire 9 is wound around the outer periphery of the cable core 10 to form a horizontally wound shield. Similarly, the tape can be wound around the cable core 10 by following the outer periphery of the cable core 10 that travels while rotating the tape supplied from the tape supply (see, for example, Patent Document 1).

In this way, by placing a plurality of shield strands and tape along the outer periphery of the cable core 10 that travels while rotating, it is possible to perform side-winding shield and tape winding in the same process.

  Next, an example of a manufacturing apparatus for manufacturing such a shielded cable will be described with reference to FIG.

  In FIG. 4, the manufacturing apparatus of the present embodiment includes a rotary supply 100 on which a supply bobbin 3 around which the cable core 10 is wound is mounted, and the cable core 10 is supplied from the rotary supply apparatus 100.

  Then, the laminated shield tape 50 supplied from the tape supply 6a is guided by the tape guide 2a and wound around the outer periphery of the cable core 10 to form a first shielding layer.

  Next, the plurality of shield strands 9 led to the outer periphery of the first shielding layer on the cableable core 10 through the shield guide 1 form a second shielding layer made of a metal shield. The shield guide 1 and the shield wire 9 are always in contact with each other.

  Therefore, an electrical circuit is formed between the second shielding layer made of a metal shield, the shield guide, the laminated shield tape, and the tape guide, and the tape guide 2a and the shield guide 1 are always electrically connected. From this, by detecting the conduction between the tape guide 2a and the shield guide 1, it is possible to continuously detect that the tape surface of the laminated shield tape is wound around the cable core without being inverted.

  Further, when the laminated shield tape is reversed, the conduction between the first shielding layer and the second shielding layer is lost, so when conduction is interrupted between the shield guide 1 and the tape guide 2a, If the manufacturing apparatus is stopped by feeding back the situation to the driving part of the manufacturing apparatus, the laminated shield tape will not be manufactured in an inverted state.

  The present invention focuses on the presence or absence of conduction between the metal shield and the metal vapor deposition layer of the laminated shield tape, and by detecting the conduction, it is determined that the surfaces of the tape are continuously the same surface. This is a shielded cable manufacturing apparatus. Here, the cable core 10 has been described as having a structure in which the inner insulating layer 20 is provided on the outer periphery of the central conductor 11, but the structure of the cable core 10 is not limited to this structure. The structure which twisted the insulated wire etc. may be sufficient. In addition, the metal shield has been described by taking a horizontally wound shield including a plurality of shield strands 9 as an example, but the metal shield is not limited to this structure, and may be a metal tape or a braided shield.

  Further, the presence or absence of conduction between the shield guide 1 and the tape guide 2a in which the metal shield and the metal vapor deposition layer of the laminated shield tape are in constant contact may be detected by measuring voltage, current and resistance. It can be confirmed that the tape surface is in the same direction over the entire length. Thus, since it is only necessary to confirm the presence / absence of conduction between the shield guide 1 and the tape guide 2a, it can be easily installed in existing equipment.
