Field of the Invention The present invention relates to a flat type coaxial wire harness in which a plurality of coaxial cables are arranged on one side. [Prior Art] A coaxial cable is composed of a center conductor 'overlying an insulator of the center conductor, an outer conductor covering the periphery of the insulator, and an outer cover. In a small electronic device such as a mobile device, for example, a very thin coaxial cable having a cable outer diameter of 〇.35 mm or less and a center conductor diameter of 0.1 mm or less can be used. We have assembled a coaxial bundle of a plurality of such ultra-fine coaxial cables arranged on one side to be assembled in an electronic device. In addition to the flat wiring member, there is an FPC (flexible printed circuit board) cable, but it is not suitable for high-frequency signal transmission due to poor noise characteristics. Japanese Laid-Open Patent Publication No. 2006-222059 (Patent Document 1) discloses that an insulator and an external sheath are arranged in a planar shape with a coaxial cable of PFA (tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer). FEP (tetrafluoroethylene·hexafluoropropylene copolymer) is a flat wire bundle which is melted as a laminated sheet of EPTFE (porous polytetrafluoroethylene) of a molten layer. PFA is a material that is heated and cannot be remelted. When it is heated to melt, it causes great damage. Therefore, in the coaxial wire harness described in Patent Document 1, only EPTFE is melted ‘ without melting PFA. Therefore, the adhesion between the two is not so strong. The lines are immediately scattered and difficult to use as wiring harnesses. Further, the coaxial harness described in Patent Document 1 can only be assumed to have a linear shape, and -3-201112277 cannot form an arbitrary shape. Further, the flat type coaxial harness which is externally pressed and covered around a plurality of coaxial cables is also limited to a linear shape. [Problem to be Solved by the Invention] An object of the present invention is to provide a coaxial wire harness which can be formed into a flat and curved shape and has high durability. [Means for Solving the Problem] In order to achieve the object, a coaxial wire harness is provided which is formed by arranging a plurality of coaxial cables on one side to form a flat coaxial wire harness having a center conductor and covering the center conductor. The insulator, the outer conductor covering the periphery of the insulator, and the remelted material having a lower melting point than the material of the insulator are formed by melting and bonding one of the plurality of coaxial cables in the longitudinal direction. In the coaxial wire harness of the present invention, the material of the externally remelted material such as an ethylene-tetrafluoroethylene copolymer' insulator is, for example, a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer. The bonded portion is formed by arranging a sheet of the same material as the outer remelted material on one side or both sides of one of the plurality of coaxial cable length directions, or the sheet may be welded to the outside. The combined portion has a plurality of portions, and a plurality of coaxial cables may have a curved shape between at least one of the combined portions. -4- 201112277 [Embodiment] Fig. 1 is a view showing a perspective view of a coaxial harness 15 according to a first embodiment of the present invention. Figure 2 is a cross-sectional view of the 11-11 of the coaxial harness 1 in the manufacture. The coaxial beam 15 is such that a plurality of coaxial cables 10 are arranged on one surface to be integrated as described below. The coaxial cable 1 has a center conductor (internal conductor) 11, an insulator 12 covering the center conductor 11, an outer conductor 13 surrounding the insulator 12, and an outer periphery of the outer conductor 13. In the case of the center conductor 11, copper or copper alloy wires of tin or silver are mainly used, and in the case of the outer conductor 13, mainly tinned copper wires or copper alloy wires are used. A remelted material having a lower melting point than the material of the insulator 12 is used in the outer portion. The coaxial beam 15 is assembled by using a jig or the like so that the coaxial cables 1 adjacent to the coaxial cable 10 are in contact with each other, and the length direction (long direction) of the coaxial cables 10 is combined by melting the outer portion 14 ) formed in one part. Hereinafter, the combined portion is referred to as a joint portion (10a, 10b, l〇c, l〇d). (In Fig. 1, in order to make each coaxial cable 〇 obvious, the coaxial cable 10 is separated except for the joint portion as shown, but in reality the coaxial cable 10 is at least in contact with the straight portion. ). In the coaxial wire harness 15, since the material of the insulator 12 is a material having a higher melting point than the material of the outer material 14, the outer layer 14 can be melted at a temperature at which the insulator 12 does not melt. Therefore, the insulator 12 in the coaxial harness 15 is not damaged and has high durability. In this way, by connecting the coaxial cables 10 to form the coaxial harness 15, it is possible to form not only a flat type of FPC but also various wiring materials of the shape of 201112277, which can also realize wiring with high noise performance. material. Furthermore, even in the case of using a very thin coaxial cable having an outer diameter of 〇.35mrn and a diameter of the center conductor of 0.1mm or less, especially in the case of using a coaxial cable which is generally called a very thin AWG40. The case of the extremely thin coaxial cable 'can also constitute a coaxial harness 15» which can achieve the above effects. Next, the melting method for forming the joint portions 10a, 10b, l〇c, i〇d 14 will be described. First, the coaxial cable 10 constituting the coaxial harness i5 is arranged in a planar shape so that adjacent coaxial cables 1 are in contact with each other at least in a straight line portion. Next, as shown in Fig. 2, the two sides of the coaxial cable 10 that are in contact with each other are heated by a heat source 30 from a heating wafer or the like to 'melt the outer coaxial cables 10, 14 to make the adjacent coaxial cables 1〇. The outer portions are welded to each other and form a joint portion. In the coaxial harness 〖5, there are 4 joints (l〇a, 10b, 10c, l〇d). Each of the joints may be formed in order, or a heat source may be disposed at four places and formed at the same time. In the coaxial harness 15, when the coaxial cables 1 are arranged, the coaxial cables 1 are bent at appropriate places between the joint portion 10b and the joint portion 100c. More specifically, a curved groove is formed in advance in the jig, and the coaxial cable 10 is placed in the groove to determine the shape of the coaxial wire bundle 15. (In the curved portion, the lengths of the coaxial cables 10 are different.) In the coaxial bundle 15, the plurality of joint portions are formed, and the coaxial cables 1 are formed into a curved shape between at least one joint portion. That is, the coaxial harness 丨 5 is also formed into a curved shape. As a result, according to the coaxial harness 15, a flat and curved shape can be formed and it can be maintained with high durability. Further, the heat source 3 is placed only on the one-side side of each of the coaxial cables 1 - 00 - 201112277, and the same line 10 may be welded only by heating from one side. Alternatively, the heat source 30 may be directly contacted with the coaxial cables to fuse the coaxial cables 10'. The coaxial cables 1C may be heated from the heat source 30 to fuse the coaxial cables 10. In the coaxial harness 15, one end is connected to the connector 21, and at the same time, the front end of the joint portion 〇d (the front end opposite to the connector 21) is provided with the finger 22, and the coaxial harness 15' is bundled and then the other one of the coaxial bundles 15 Connect the connector 23. In this way, 'in the coaxial harness 15' can also be bundled. In the first embodiment, a coaxial line in which seven coaxial cables are arranged is exemplified, but the number of cables of the coaxial cable may be any number as long as it is plural. Further, although the shape is made to be curved, it may be a coaxial harness of the shape. Next, a combination of the insulator 1 2 and the outer layer 14 as described above is exemplified: for example, the material of the insulator 12 is PFA (tetrafluoroethylene-perfluoroalkyl ether copolymer), and the remelted material of the outer layer 14 is made into ETFE. (ethylene ethylene copolymer).

At this time, 30 is considering the melting point of ETFE, and can also be set to, for example, 2 5 0 to 2 60 ° C.

Ethylene-tetrafluoroethylene: There is no need for heat source for ETFE 201112277 Fig. 3 is a view showing the coaxial harness 16 of the second embodiment of the present invention. Figure 4 is a cross-sectional view of the IV-IV of the mid-coaxial harness 16 in the manufacture. (In Fig. 3, in order to make each coaxial cable 1〇 easy to see, the coaxial cable 1 外 outside the joint is separated as shown, but in reality the coaxial cable 10 is at least in the straight portion. contact). The joint portion of the coaxial beam 16 is arranged such that a plurality of (for example, seven) coaxial cables 1 〇 are in contact with each other, and then arranged on both sides of a length direction of the seven coaxial cables 1 , The sheet 20 of the same material as the remelted material of the outer layer 14 is thereafter welded to the outer layer 14 by adding the heat source 30 from both sides of the sheet 20. Here, as for the material of the outer cover 14 and the insulator 12, the same thing as the first embodiment can be employed. The sheet 20 is disposed at four places on the coaxial cable 1b. By preferably arranging four heat sources and heating to apply heat to the sheet 20, the combination of four places can be formed as shown in FIG. Parts 20a, 20b, 20c, 20d. Next, the coaxial cables 10 are integrated by the joint portions 20a, 20b, 20c, and 20d. Even in the case of the coaxial harness 16, the same as the coaxial harness 15, when the coaxial cables 10 are arranged, the coaxial cables 10 are bent at appropriate positions between the joint portion 20b and the joint portion 20c. In this way, even in the second embodiment, the plurality of joint portions can be formed, and the coaxial cable 1 can be formed into a curved shape between at least one joint portion, that is, the coaxial strand is formed into a curved shape. In the second embodiment, as in the first embodiment, the connector 21 is connected to one end of the coaxial harness, and the package portion 22 is provided at the front end of the joint portion 20d (the front end opposite to the connector 201112277 21). At the other end of the wire harness, the connector 23 is connected. As a result, even in the second embodiment, as shown in the package unit 22, it can be bundled from the middle. Further, even in the second embodiment, a coaxial wire harness having a linear shape can be formed. Moreover, the sheet 20 may be welded only on one side of each of the coaxial cables, or the heat source 30 may be directly in contact with the sheet 20, and the sheet and the coaxial cable may be welded, or may be indirectly heated from the heat source 30 to the sheet and Coaxial cable to make these welds. As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained. Further, in the first embodiment, when the outer cover 14 is thin, the area of the portion where the coaxial cable 1 is welded is reduced, but in the second embodiment, the sheet 20 is melted, and the cross-sectional view of Fig. 4 is shown. By embedding the recesses between the respective lines, the area of the molten space is increased, so that the adhesion of the respective lines is further increased, and the durability against strong impact such as twisting is further excellent. Further, the structure of the coaxial harness of the second embodiment is flat like FPC, and can be made into wiring materials of various shapes. For example, if the center conductor 1 1 is AWG 46 (diameter 0.03 984 mm), the thickness of the double-sided sheet 20 may be set to 0.3 mm. Furthermore, the structure is more excellent in noise characteristics than FPC. By forming the packing portion 22 at the time of bending at the time of wiring, the bending property can be improved. In the first embodiment and the second embodiment, the joint portion is formed only by a part of the joint portion 10a, 10b, 10c, 10d or the joint portions 20a, 20b, 20c, 20d in the longitudinal direction, but may be in the longitudinal direction. Make all the parts. -9 - 201112277 The coaxial cable of the embodiment 10 uses 20 sheets of the central guide of the AWG 4 6 and the thickness of the outer cover 14 of 0.017 mm, 20 pieces, 20 pieces, arranged without intervals, with a width of 2 mm, a sheet 20 ( The ETFE tape is heat-pressed from both sides and 260 ° C right), and the sheet 20 of the ETFE welded to the coaxial cable 10 is integrated to form a coaxial wire harness. The mixture was immersed in a constant temperature bath at 85 ° C for 96 hours, and again, {] ° C, 95% RH) for 96 hours, and no change or stripping was used for the same purpose. For the sake of comparison, the center conductor has the same diameter and thickness, and is used as a PFA test as conventionally used. The FEP tape with a gap of 2 mm and a thickness of 0.05 mm between the two coaxial cables is clamped from both sides, i.e., around the melting point, and the FEP tape and the PFA are not bundled. [Industrial Applicability] Wiring in a small electronic device such as a high-frequency, high-definition, and free-of-the-box device is extremely suitable. [Brief Description] FIG. 1 is a view showing a first embodiment of the present invention. Body 11, cable outer diameter. The coaxial cable has a thickness of 0.05 mm (the melting point of the ETFE is left and the ETFE is the coaxial wire harness, that is, the g is high temperature and high humidity (65 detach, and can be tested with the conventional cable outer diameter and the outer coaxial cable). Since the width is set to 310 ° C (PFA is melted, it cannot be made large, so 作为-10-201112277 as a coaxial wire harness for action) Fig. 2 is a cross-sectional view taken along the line II-II of the coaxial harness of the first embodiment in the manufacture.
