Fig. 3 is a cross-sectional view showing an example of a wire for a movable member wiring.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in Fig. 1, the flat wire 100 for movable member wiring according to the embodiment of the present invention is formed by arranging a plurality of air pipes 102 in parallel by a method such as fusion (for example, hot air fusion). The inner diameter of the air tube 102 is formed to be the size of the pluggable wiring line 101. In the plurality of air tubes 102, a part of the air tubes can be inserted into the air tube for driving air to insert the movable member wiring line 101. In other air pipes, the movable wire harnessing wire 101 may be inserted into all the air pipes (not used as a air pipe), or a part of the air pipes may not be used.

Hereinafter, the flat wire 100 for movable member wiring used for mixing the air pipe and the movable member wiring wire will be described. The air pipe 102 into which the movable member wiring wire 101 is inserted and the air pipe 102 in which the movable member wiring wire 101 is not inserted may be disposed in any order, and a plurality of movable member wiring wires 101 may be arbitrarily inserted into one air pipe 102. .

The movable member wiring cable 101 may be a cable or an optical fiber cable. For example, as shown in FIG. 2, the insulator 105 which is the outermost layer is coated with a plurality of conductors 103. The circumference of the conductor 104 is formed.

At this time, the insulator 105 is preferably an ethylene-tetrafluoroethylene copolymer (ETFE) resin, a tetrafluoroethylene-hexafluoropropylene copolymer (FEP) resin, or a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA). Resin, or It is composed of a fluororesin having low dust generation properties such as polytetrafluoroethylene (PTFE) resin.

With this, it is possible to suppress the occurrence of dust accompanying abrasion or wear accompanying contact between the movable member wiring cable 101 and the air tube 102 in the air tube 102 in which the movable member wiring cable 101 is inserted.

Further, for example, as shown in FIG. 3, the movable member wiring cable 101 may be wound around the twisting line 107 formed by twisting a plurality of electric wires 106 via the interposer 108, and around the belt 109. The cover is formed by a hood such as a woven shield or a transverse winding shield which is woven or wound by a plurality of root threads, and a jacket 111.

Preferably, the outer casing 111 is composed of an inner layer 112 and an outer layer 113. The inner layer 112 is made of a highly flexible resin such as a polyvinyl chloride resin, a polyurethane resin or a polyolefin resin, and the outer layer 113 is formed on the inner layer. The outer periphery of 112, and dust generation properties such as ethylene-tetrafluoroethylene copolymer resin, tetrafluoroethylene-hexafluoropropylene copolymer resin, tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin or polytetrafluoroethylene resin It is composed of a low fluororesin and becomes the outermost layer.

With this, it is possible to suppress the occurrence of dust accompanying abrasion or wear accompanying contact between the movable member wiring cable 101 and the air tube 102, and the movable member wiring cable 101 can be applied to the air tube 102 of the movable member wiring cable 101. High flexibility.

Further, although the outer casing 111 may not be provided, only the plurality of electric wires 106 may be concentrated as the movable member wiring cable 101 with the belt 109, but it is necessary to use the outermost belt 109 as an ethylene-tetrafluoroethylene copolymer. A fluororesin having low dust generation properties such as a resin, a tetrafluoroethylene-hexafluoropropylene copolymer resin, a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin or a polytetrafluoroethylene resin is formed.

Referring again to FIG. 1, the air tube 102 is provided with a high elastic tube 114 and an outer layer 115. The high elastic tube 114 is made of a polyurethane resin or a nylon resin, and the outer layer 115 is formed outside the high elastic tube 114. The circumference is also composed of an insulating material containing a fluororubber and a fluororesin, and the outer layer 115 is fused to each other.

The high elastic tube 114 serves to increase the flexibility of the air tube 102 and improve the flexibility of the flat cable 100 for the movable member wiring, and the outer layer 115 serves to maintain the flexibility of the air tube 102 while maintaining the flexibility of the air tube 102. The wearability or dust generation of the gas pipe 102 is improved. In addition, since fluorine rubber is contained, the occurrence of static electricity can be reduced.

Here, the insulating material preferably contains a fluorine rubber and a fluororesin in a mass ratio of 95:5 to 20:80, and the fluororesin preferably contains a polytetrafluoroethylene and a molten fluororesin in a mass ratio of 99.5:0.5 to 75:25. . For the insulating material that satisfies these conditions, DAI-EL (registered trademark) FluoroTPV manufactured by DAIKIN Industries Co., Ltd. is mentioned.

With this, it is possible to form a high-abrasion property and a low dust generation property of the fluororesin, and high flexibility and high elasticity of the fluororubber (elasticity is required to receive the flat wire 100 for the movable member wiring when the U-shaped bending is repeated) Straightness improves the outer layer 115.

Therefore, by providing the outer layer 115, the straightness of the flat wire 100 for the movable member wiring can be improved when the flat wire 100 for the movable member wiring is subjected to the flexibility or the non-destructive U-shaped bending property of the U-shaped bending.

Further, the outer layer 115 also has high oil resistance, high chemical resistance, and high weather resistance of the fluororesin, so even in an oil environment, an acidic environment, an alkaline environment, and an ultraviolet exposure environment, A flat cable 100 for movable member wiring can also be used.

Further, the outer layer 115 preferably has a thickness of 0.2 mm or more and 0.4 mm or less. The reason is that when the thickness of the outer layer 115 is less than 0.2 mm, the flat wire 100 for the movable member wiring is wrinkled when subjected to the reverse U-shaped bending, and finally the outer layer 115 is wrinkled, and finally the crack is formed and the elastic tube 114 is exposed. . In addition, because the thickness of the outer layer 115 exceeds 0.4 mm, The resilience of the flat cable 100 for the movable member wiring is increased when the U-shaped bending is repeated, and the pressure applied to the structure such as the cable drag chain from the flat cable 100 for the movable member wiring is increased. The service life of structures such as cable drag chains is shortened.

Further, the thickness of the outer layer 115 is preferably 1/5 or more and 1/2 or less of the thickness of the high elastic tube 114. The reason is that when the thickness of the outer layer 115 is less than 1/5 of the thickness of the high elastic tube 114, it is difficult to maintain the straightness of the flat wire 100 for the movable member wiring, and the flat wire 100 for the movable member wiring is drooped, with the movable member The flat cable 100 for wiring is in contact with a structure such as a cable drag chain, and during the use period (for example, five years) of the flat cable 100 for the movable member wiring, the outer layer 115 is cut off and the high elastic tube 114 is exposed. Hey. Further, when the thickness of the outer layer 115 exceeds 1/2 of the thickness of the high elastic tube 114, the flexibility of the flat wire 100 for the movable member wiring is impaired, and it is difficult to maintain the resistance of the U-shaped bending resistance as in the past. the same. Further, since the insulating material such as DAI-EL (registered trademark) FluoroTPV is expensive compared with other resins, the product cost is remarkably increased when used in excessively large amounts.

Further, the gas pipe 102 is preferably further provided with an inner layer 116 formed on the inner circumference of the high elastic tube 114, and composed of an ethylene-tetrafluoroethylene copolymer resin, a tetrafluoroethylene-hexafluoropropylene copolymer resin, and tetrafluoroethylene. It is composed of a fluororesin having low dust generation properties such as an ethylene-perfluoroalkyl vinyl ether copolymer resin or a polytetrafluoroethylene resin.

With this, it is possible to suppress the occurrence of dust accompanying abrasion or wear accompanying contact between the movable member wiring cable 101 and the air tube 102 in the air tube 102 in which the movable member wiring cable 101 is inserted.

As described above, in the flat cable 100 for movable member wiring, since the outer layer 115 made of an insulating material containing fluororubber and fluororesin is provided on the outer circumference of the high elastic tube 114, it is possible to improve the movement when the U-shaped bending is applied. Straightness of the flat cable 100 for wiring Abrasion and dust occurrence.

Further, in the case of the flat cable 100 for the movable member wiring, since the inner diameter of the air tube 102 is formed so that the movable member wiring cable 101 can be easily inserted and removed, the movable member wiring cable 101 inserted into the air tube 102 can be exchanged. The movable member wiring wire 101 inserted into the air pipe 102 is taken out and used as a gas pipe, or the movable member wiring wire 101 is reinserted into the air pipe 102 that is used as a gas pipe. In this way, the air pipe 102 into which the movable member wiring wire 101 is inserted and the air pipe 102 in which the movable member wiring wire 101 is not inserted can be disposed in an arbitrary order and the number of the air, and the movable member can be flexibly changed depending on the type of product to be manufactured. The specification of the wiring wire 101 or the number of the air pipes 102.

Therefore, according to the present invention, it is possible to suppress the occurrence of abrasion or dust accompanying abrasion, and it is possible to flexibly change the specification of the movable member wiring cable 101 or the number of the air tubes 102 depending on the type of the product to be manufactured.

In addition, when the flat cable 100 for the movable member wiring is subjected to the U-shaped bending, the straightness is high, and it is difficult to sag even when it is wired for a long distance, so that the use of the cable drag chain can be avoided, which contributes to surface mounting. The miniaturization of devices and the like.

[Examples]

Next, a specific example of the present invention will be described.

The outer layer of a highly elastic tube made of a polyurethane resin having an inner diameter of 4 mm and an outer diameter of 6 mm was coated with DAI-EL (registered trademark) FluoroTPV to form an outer layer having a thickness of 0.2 mm, and 8 was produced. A gas pipe having an outer diameter of 6.4 mm allows the gas pipes to be fused side by side. Among the eight gas pipes, three gas pipes are used as the gas pipe, and a wire for a movable member wiring such as a power source wire or a signal wire is inserted into the remaining air pipe to prepare a flat wire for the movable member wiring.

Thereafter, the flat wire for the movable member wiring is held on the precision manufacturing line without being held by the wire drawing chain, and as a result, even if it is repeated The moving distance of the U-shaped bending is 1.5 m, and there is no case where the flat cable of the movable member is drooping. In addition, even under the conditions of a bending radius of 38.4 mm (6 times the outer diameter of the air pipe), a folding speed of 30 times/min, and a moving distance of 1 m, the U-shaped bending of 10 million times or more is performed, and abrasion or wear is not caused. Dust occurs.

As described above, the effects of the present invention are confirmed.
