[Industrial applications]

The present invention relates to a composite cable containing a signal flat cable 3 and a power cable 2 which is mainly used as a control cable for an NC processing machine or the like. The present invention relates to a composite cable 1 including a signal line and a power line, which contributes to cost reduction, compactness, high reliability and safety by adopting the method.

[Prior art]

In recent years, production equipment such as NC processing machines, conveyor equipment such as conveyors, inspection equipment using CCD cameras, etc. and the sequencer / computer that controls them have been operating at a rapid tempo with the trend of automation and power saving. It has increased. In the conventional flat cable with signal sheath 11 ', as shown in Fig. 2, a space is provided at the center or an elastic interposition 9'to prevent collapse, and the signal flat cable 3'is provided around it. It is generally known that a spirally wound structure is formed into a round shape. As described above, conventionally, it is necessary to manufacture the flat cable with signal sheath 11 ′ and the power supply cable for driving the equipment by separate cables, and bundle and wire them, so it is inevitable It was worth noting that it had to be laid. As a result, the number of cables has increased, and it has been unavoidable. Therefore, as a matter of course, an operator or a machine by an automatic device causes a catching accident or an error in miswiring, and an improvement is required.

[0003]

[Means for Solving the Problems]

In order to solve these problems, the present invention has made extensive studies, and as a result, stopped the conventional multi-strand laying method and put together the single-strand laying method, thereby reducing the cost, making the compact, high reliability, The purpose is to provide a composite cable 1 containing signal and power supply lines that contributes to safety, and the main point is to provide a power supply cable 2 with a large conductor size consisting of one or a plurality of wires provided in the center. A plurality of insulating core wires 8 are arranged parallel to each other in the lengthwise direction, and the signal flat cable 3 including a repeating portion of the integrated portion A and the separated portion B is spirally wound and rounded. This is a composite cable 1 containing signal and power supply lines, characterized by being molded, optionally provided with a shield 5, and provided with a sheath 4 thereon.

【Example】

Hereinafter, embodiments of the composite cable 1 including signal and power lines of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1A shows a first embodiment of a composite cable 1 including signal and power supply lines according to the present invention, and is a sectional view for a two-phase power supply and a three-phase power supply, respectively. As is apparent from the figure, the composite cable 1 with signal and power supply lines of the present invention has a signal cable around the power supply cable 2 with a large current capacity, which is provided with one or more conductors in the center. The cable 3 is wound in a spiral shape to be formed into a round shape, and the sheath 4 is provided thereon. FIG. 1B shows a sectional view of a second embodiment of the composite cable 1 including signal and power lines of the present invention, in which the signal flat cable 3 is formed into an S shape or an inverted S shape (not shown). The structure is such that it is formed into a round shape and the sheath 4 is provided on it. FIG. 1 (c) shows a cross-sectional view of a third embodiment of the composite cable 1 including signal and power supply lines of the present invention, in which a shield 5 is provided around the power supply cable 2 and around the signal flat cable 3. It is the structure provided. Here, the structure of the signal flat cable 3 is made up of a plurality of insulating core wires 8 arranged in parallel in the lengthwise direction and repeating of the integral part A and the separating part B (see FIG. 1 ( D))). The signal flat cable 3 is not limited to this, and may be a twisted pair flat cable formed by twisting two cables.

FIG. 1D shows an example of use of the composite cable 1 including signal and power lines of the present invention. As is apparent from the figure, the signal flat cable 3 is unraveled from the sheath 4 and attached to the collective press-connecting connector 6 and the terminal-treated one is connected to the male connector 9 of the other device, while the power cable 2 is connected to the other device. It may be connected to the connection terminal block 7 of the device. In the conventional method, two cables, a signal line and a power line, are required, but the signal and power line composite cable 1 of the present invention requires only one cable. As is clear from the above, according to the composite cable 1 with signal and power supply lines of the present invention, the number of cables can be reduced, which not only contributes to cost reduction, but also the wiring is neat and compact. It becomes possible to measure. In addition, there are less chances of being caught or accidental wiring mistakes, and the appearance is neat, contributing to safety and high reliability.

Up to now, the description has been given by taking a typical flat cable as an example, but it goes without saying that various modifications are included within the scope of the present invention in the design such as the shield structure provided inside and outside and the modified flat cable. Nor.
