Embodiment
Below, based on accompanying drawing, the preferred embodiment of the present invention is described.
As shown in Figure 1 (a) and Fig 1 (b) shows, the feature of the heat-resistant, flat cable 10 involved by present embodiment is, the fibril 12 having many wires 11 arranged side by side and inweave in many wires 11, fibril 12 carries out false twisting processing to the many fluororesin fibers with more than 150 DEG C thermal endurances and is formed.
The insulating barrier 14 that many wires 11 have conductor 13 and formed around conductor 13, insulating barrier 14 can use any materials.Such as, fluororesin can be used when there is heat-resistant, flat cable 10 thin footpathization and requiring, specifically, can select from the combination of any one tetrafluoroethylene-ethylene copolymer (ETFE), tetrafluoraoethylene-hexafluoropropylene copolymer (FEP), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA) or polytetrafluoroethylene (PTFE) or more than two kinds.Because the dielectric constant of these fluororesin is low to moderate 2.1 to 2.6, and the lower thickness of insulating barrier 14 can be made, therefore can make the thin footpath of heat-resistant, flat cable 10.In addition, when there is softness requirements to heat-resistant, flat cable 10, can be resin from the polyolefin-based resins such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyurethane (PU) is resin, selecting in the combination of any one or more than two kinds their crosslinked resin or their Foamex.Although these resin flexibilities are thermal endurance, poor fire well, carrying out covering surfaces by inweaving fluororesin fiber described later, under the state keeping flexibility, thermal endurance, anti-flammability can be given to heat-resistant, flat cable 10.In addition, further, although Corvic, polyurethane resin rub resistance, abrasion performance are poor, but carry out covering surfaces by inweaving fluororesin fiber described later, thermal endurance, anti-flammability can be given to heat-resistant, flat cable 10 under the state keeping flexibility, even if carry out the situation of distribution at small, do not worry that insulating barrier 14 produces scratch, scratch etc. yet.
In addition, many wires 11 can have the sheath of screen and its periphery further in the periphery of insulating barrier 14, sheath can use any materials according to object in the same manner as insulating barrier 14.
In addition, above-mentioned crosslinked resin can use the resin manufactured by the common cross-linking method such as chemical crosslinking, electron beam crosslinking, and above-mentioned Foamex can use the resin manufactured by the common foaming such as chemical blowing, physical blowing.
Fibril 12 is the many elastomers carrying out false twisting processing to the many fluororesin fibers with more than 150 DEG C thermal endurances and formed as mentioned above.Here, so-called false twisting processing, it is representational is by forward twisted fibers, the solid shape by the fiber heating after twisting, last reverse twisted fibers and backtwisting, thus fiber is given to the processing method of retractility (flexibility), crimp property.
Many fluororesin fibers are such as made up of tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer.The excellent heat resistance of tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, has the thermal endurance of more than 150 DEG C.
By this fibril 12 is inweaved in many wires 11, and only 1 fluororesin fiber is inweaved compared with the situation in many wires 11, the local stress that fibril 12 pairs of electric wires 11 produce can be reduced.
Specifically, when the fibril be made up of 1 fluororesin fiber is inweaved many wires 11, because stress when inweaving fibril is produced on electric wire 11 by 1 fluororesin fiber, therefore, this stress is made to concentrate the part produced at electric wire 11 partly.
On the other hand, when the fibril be made up of many fluororesin fibers 12 is inweaved many wires 11, stress during owing to being inweaved by fibril 12 is produced on electric wire 11 by many fluororesin fibers, therefore, produce with making this stress dispersion many fluororesin fibers respective on.
Therefore, it is possible to reduce the local stress of fibril 12 pairs of electric wires 11 generations, the many wires 11 tied up not easily produce little the bending of bending radius, be also difficult to produce broken string even if heat-resistant, flat cable 10 bears alternating bending electric wire 11.
In addition, due to retractility (flexibility), the crimp property excellence of fibril 12, therefore can not damage the pliability of whole cable, even if carry out distribution to the part that heat-resistant, flat cable 10 bears alternating bending, the broken string life-span of electric wire 11 is also longer compared with heat-resistant, flat cable 30 in the past.
Therefore, according to heat-resistant, flat cable 10, although use fluororesin fiber as the material of fibril 12, also sufficient resistance to bend(ing) can be realized.
In addition, fibril 12 inweaves in electric wire 11 owing to being scatter separately by many fluororesin fibers by false twisting processing, therefore the surface of electric wire 11 can be covered with fluororesin fiber, even if the insulating barrier 14 of electric wire 11, sheath employ the low resin of thermal endurance, also can not damage the characteristics such as the flexibility of electric wire 11, thermal endurance can be given to electric wire 11.
Further, based on same reason, anti-flammability, rub resistance and/or abrasion performance can be given to electric wire 11.
In addition, easily untie because fibril 12 can cut off at an arbitrary position, therefore, it is possible at many wires 11 separately for being processed by different distributing terminal with different length and be connected with various connector (such as PCB substrate, FPC, MFJ) under independently state.
Further, any impact can not be produced on the insulating barrier 14 of electric wire 11 because distributing terminal adds man-hour, therefore, not worry as heat-resistant, flat cable 30 in the past, the insulating barrier 14 of electric wire 11 splits and exposes the conductor 13 of electric wire 11, causes the problem that electric short circuit, defective insulation are such.
In addition, even if when heat-resistant, flat cable 10 is used as the periphery distribution of internal combustion engine, owing to can absorb by the fibril 12 of retractility (flexibility), crimp property excellence the vibration be applied on heat-resistant, flat cable 10, therefore, without the need in order to implement for preventing arranging other components by the vibration countermeasure vibrating the fatigue fracture that causes etc. on heat-resistant, flat cable 10, other are coated to, and can realize the miniaturization of heat-resistant, flat cable 10.
Then, the manufacture method of heat-resistant, flat cable is described.
The manufacture method of the heat-resistant, flat cable involved by present embodiment, it is characterized in that there is following operation: false twisting processing is implemented to the many fluororesin fibers with more than 150 DEG C thermal endurances and makes the operation of fibril 12 and in many wires 11 arranged side by side, inweave the operation of fibril 12.
For the operation inweaving fibril 12 in many wires 11 arranged side by side, the fibril 12 of crispaturaing is extended while inweave in many wires 11.Thus, many wires 11 are tied up securely, can prevent vibration owing to applying heat-resistant, flat cable 10 etc. and make that many wires 11 are untied, electric wire 11 contacts with each other, damage the insulating barrier 14 of electric wire 11.
Then heat-resisting wire harness is described.
As shown in Figure 2, the feature of the heat-resisting wire harness 20 involved by present embodiment is, has heat-resistant, flat cable 10 and is connected to the connector 21 of terminal of heat-resistant, flat cable 10.Connector 21 is such as connected to each branch terminal of heat-resistant, flat cable 10.
In this heat-resisting wire harness 20, easily untie, therefore, it is possible to connector 21 is connected to each branch terminal of heat-resistant, flat cable 10 owing to the fibril 12 of heat-resistant, flat cable 10 can be cut off in arbitrary position.That is, can according to distribution situation, distribution layout and realize the heat-resisting wire harness 20 of various form.
As mentioned above, according to the present invention, although a kind of use fluororesin fiber can be provided as material, the heat-resistant, flat cable that resistance to bend(ing) is also excellent and its manufacture method and the heat-resisting wire harness of fibril.
