Detailed description of the invention
Hereinafter, according to accompanying drawing, suitable embodiment of the present utility model is illustrated.
As it is shown in figure 1, the movable part conductor arrangement cable 100 involved by suitable embodiment of the present utility model possesses cable core 101 and the protecting film 102 being formed at around cable core 101.
Cable core 101 possess such as twisted wire 103, bury underground in gap present on the circular section of twisted wire 103 be situated between at thing 104, the band 105 being wound in around twisted wire 103, the screen 106 being arranged at the surrounding with 105 and the sheath 107 being arranged at around screen 106.
Twisted wire 103 is by by stranded for many electric wires 108 and formed, and described many electric wires 108 comprise: has conductor and the insulated electric conductor of the insulator that is arranged at around conductor, have the coaxial cable etc. of inner conductor and external conductor.By burying Jie in gap present on the circular section of twisted wire 103 underground at thing 104, the configuration of many electric wires 108 is fixed, therefore, it is possible to be maintained upward by the symmetry of the twisted wire 103 of the cross-section of cable in whole cable length side, it is possible to suppression impedance variation on whole cable length direction.
Formed by the material that the lubricities such as paper, fluororesin, nylon resin or pet resin are high with 105, in the way of a part for adjacent band 105 is overlapping, carry out looping (ラ ッ プ I) when being wound around around twisted wire 103.Thus, many electric wires 108 become to be difficult to untie, and the configuration of many electric wires 108 is fixed, therefore, it is possible to be maintained upward by the symmetry of the twisted wire 103 of the cross-section of cable in whole cable length side, it is possible to more effectively suppress the impedance variation on whole cable length direction.
Screen 106 comprises: the braid shielded thing that the braiding of many single lines formed, the wrapped screen of spiral type etc. formed by many single wires wound curls.By being arranged around screen 106 at twisted wire 103, it is possible to increase electromagnetic interference (the Electro Magnetic Interference of movable part conductor arrangement cable 100；EMI) characteristic etc..
Sheath 107 is formed by any one in Corvic, polyurethane resin or halogen-free polyolefin resin.The flexibility of these materials, pliability are high, the sheath 107 therefore formed by these materials by employing, it is possible to increase the flexibility of movable part conductor arrangement cable 100, pliability, it is possible to increase the resistance to bend(ing) of movable part conductor arrangement cable 100.
Protecting film 102 makes fluorocarbon oil be dissolved or dispersed in the mixed liquor of solvent by coating around cable core 101 and is dried and is formed, and its thickness is the degree of below more than 10 μm 50 μm at most.
More specifically; such as; fluorocarbon oil is made to be dissolved or dispersed in room temperature volatile organic solvent to modulate mixed liquor; after being coated the surrounding of cable core 101; make this cable core 101 at room temperature natural drying, make the room temperature volatile organic solvent volatilization that mixed liquor is comprised such that it is able to fluorine tunicle is fixed on the pettiness matsurface being inevitably present on cable core 101 surface; form the thinnest protecting film 102, manufacture movable part conductor arrangement cable 100.
In addition, can be used on the low temperature volatile organic solvent less than volatilization at a temperature of the rated temperature of sheath 107 (certainly, it is alternatively room temperature volatile organic solvent) as solvent, at a temperature of the rated temperature less than sheath 107, cable core 101 is thermally dried by (such as more than 40 DEG C less than 80 DEG C), so that the low temperature volatile organic solvent volatilization that mixed liquor is comprised.Thus, fluorine tunicle is more firmly fixed at the surface of cable core 101 such that it is able to obtain the protecting film 102 being more difficult to peel off.
For fluororesin; due to its lubricity, abrasion performance height; therefore by using the protecting film 102 being made up of fluorine tunicle that movable part conductor arrangement cable 100 gives lubricity, abrasion performance; even if thus bear alternating bending at high speeds, it is also possible to suppression movable part conductor arrangement cable 100 sustains damage because of abrasion or bad because inducing product with the produced dust of abrasion.
Additionally; from for the viewpoint that movable part conductor arrangement cable 100 gives lubricity, abrasion performance; also contemplate for the coating fluororesin of extrusion on cable core 101 to form protective layer; but the hardness of fluororesin is high; and be difficult to form thin protective layer by extrusion is coating; if therefore utilizing extrusion to be coated to form protective layer, then the flexibility of movable part conductor arrangement cable 100, pliability can reduce.
In addition; the adaptation of fluororesin is low; form protective layer protective layer also cannot be made closely sealed with sheath 107 even if being therefore coated to by extrusion, can be in the generation gap, interface of sheath 107 with protective layer, and it is possible to the outward appearance expansion etc. making reason that protective layer produces be full of cracks equivalent damage occurs to constitute.
Relative to this; in movable part conductor arrangement cable 100; as previously mentioned; fluorine tunicle is fixed on the pettiness matsurface being inevitably present on cable core 101 surface and defines the thinnest protecting film 102, therefore, it is possible to do not reduce the flexibility of movable part conductor arrangement cable 100, pliability and give lubricity, abrasion performance to movable part conductor arrangement cable 100.
And; protecting film 102 can be made closely sealed with sheath 107; even if therefore movable part conductor arrangement cable 100 bears alternating bending at high speeds; protecting film 102 is also difficult to peel off from sheath 107; the generation gap, interface at sheath 107 with protecting film 102 can be suppressed; or there is to constitute the outward appearance expansion etc. of the reason making protecting film 102 generation be full of cracks equivalent damage, it is possible to more improve the resistance to bend(ing) of movable part conductor arrangement cable 100.
Additionally, fluororesin fusing point is high, form protective layer if being therefore coated to by extrusion, then sheath 107 is exposed to the high temperature of more than 250 DEG C and produces heat deterioration, sheath 107 the various characteristics of the movable part conductor arrangement cable 100 undertaken are likely to decrease.
Relative to this; in movable part conductor arrangement cable 100; as previously mentioned; after mixed liquor is coated the surrounding of cable core 101; this cable core 101 is dried at a temperature of room temperature or the rated temperature less than sheath 107 so that the solvent that mixed liquor is comprised volatilizees; thus protecting film 102 is formed on the surface of cable core 101, therefore sheath 107 will not be exposed to the high temperature of more than 250 DEG C and produce heat deterioration, it is possible to prevent the various characteristics of movable part conductor arrangement cable 100 from reducing.
Additionally, the thickness of protecting film 102 is below more than 10 μm 50 μm, more than more preferably 30 μm below 40 μm, thus lubricity, abrasion performance can be given without increasing considerably the external diameter of movable part conductor arrangement cable 100 to movable part conductor arrangement cable 100.
As it has been described above, according to this utility model, it is possible to provide bear alternating bending at high speeds even if a kind of, it is also possible to suppress the damage produced because of abrasion or the bad movable part conductor arrangement cable of the product because inducing with the produced dust of abrasion.
