The wire harness described above includes a plurality of electric wires.
[0003]
For these electric wires, shielded electric wires may be used in order to prevent external noise from entering the respective core wires. The shielded electric wire includes a shield part made of a braid having conductivity. This shield portion prevents noise from entering the core wire.
[0004]
In recent years, it has been desired to reduce the cost of the wire harness described above. For this reason, it is proposed that a plurality of electric wires not provided with the shield part are bundled, and a conductive thin film sheet having a thin conductive layer is wound around the plurality of electric wires to constitute a wire harness. With such a configuration, it is possible to reduce costs and prevent noise from entering.

For this reason, it is conceivable that the above-described ground wire cannot be reliably connected to the conductor layer. Therefore, it is difficult to release the noise that tries to enter the core of the electric wire to the outside.

[0023]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the conductor thin film with conductor according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5. As shown in FIG. 1 and FIG. 2, the conductor thin film 1 with a conductor includes an aluminum laminate sheet (hereinafter referred to as ALS) 2 as a conductor thin film sheet, and a metal piece 8.
[0024]
The ALS 2 includes a thin conductor layer 4 and a thin insulating layer 7 laminated on the conductor layer 4 and is formed in a relatively thin sheet shape. The conductor layer 4 is made of a conductive metal. The conductor layer 4 has flexibility. The conductor layer 4 is formed with a constant thickness. The conductor layer 4 contains at least aluminum or an aluminum alloy. The insulating layer 7 includes a first insulating layer 5 and a second insulating layer 6.
[0025]
The first insulating layer 5 is made of an insulating synthetic resin and is laminated on the conductor layer 4. The first insulating layer 5 is flexible and made of polyethylene terephthalate (PET) or the like. The second insulating layer 6 is made of a synthetic resin having an insulating property and is laminated on the first insulating layer 5. The second insulating layer 6 is flexible and made of polyvinyl chloride (PVC) or the like. The ALS 2 having the above-described configuration has the metal piece 8 attached thereto and is wound around the outer circumferences of the plurality of electric wires 3 as shown in FIGS.
[0026]
As shown in FIGS. 1 and 3, two metal pieces 8 are provided. Each of the metal pieces 8 is made of a conductive metal. Each of the metal pieces 8 is formed in a band shape having a constant thickness. When the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, the metal piece 8 is attached to both ends 2 a and 2 b of the ALS 2 that are spaced apart from each other along the longitudinal direction of the electric wires 3. That is, when the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, the metal piece 8 is attached to both ends 2 a and 2 b of the ALS 2 along the longitudinal direction of the electric wires 3.
[0027]
When the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, the metal piece 8 is attached to the ALS 2 in a state where the longitudinal direction is along the circumferential direction of the electric wires 3. As shown in FIG. 3, the metal piece 8 is attached to the ALS 2 with one end protruding outward from one edge in the width direction of the ALS 2. The width direction of ALS 2 is a direction along the radial direction of the electric wire 3. The metal piece 8 is overlaid on the insulating layer 7 of the ALS 2, and a part 8 a (shown in FIGS. 2 and 3) is joined to the conductor layer 4. The metal piece 8 is provided with a through hole 8b at one end protruding from one edge in the width direction of the ALS2.
[0028]
The electric wire 3 around which the ALS 2 is wound has a round cross section. The electric wire 3 includes a core wire 10 having a round cross section and a covering portion 11 that covers the core wire 10. The core wire 10 is formed by twisting one conductive lead or a plurality of conductive leads. The conducting wire constituting the core wire 10 is made of a conductive metal. That is, the core wire 10 is made of a conductive metal. The core wire 10 has flexibility. The covering portion 11 is made of a synthetic resin having insulating properties and flexibility.
[0029]
As shown in FIGS. 1 and 2, a plurality of the electric wires 3 described above are bundled, and after the tape 15 is wound around the outer periphery, the conductor thin film 1 with conductor is wound around the outer periphery. In addition, when these electric wires 3 are wired, for example in a motor vehicle etc., they connect between the auxiliary machines mounted in this motor vehicle.
[0030]
The conductor thin film 1 with a conductor has metal pieces 8 attached to both end portions 2a and 2b spaced apart from each other along the longitudinal direction of the electric wire 3 of the ALS 2. The metal piece 8 is overlaid on the insulating layer 7, and a part 8 a is joined to the conductor layer 4.
[0031]
The conductor thin film 1 with conductor is obtained by fixing a part 8a of the metal piece 8 and the conductor layer 4 of ALS2 to each other by an ultrasonic welding machine. The part 8 a forms a joint between the metal piece 8 and the conductor layer 4. In the present embodiment, as shown in FIG. 3, the part 8a is provided at three locations for each metal piece 8. That is, the metal piece 8 is attached to the ALS 2 by ultrasonic welding at three locations.
[0032]
However, in the present invention, the joining portion 8a between the metal piece 8 and the conductor layer 4 may be arbitrarily provided according to the necessary mechanical strength for fixing the metal piece 8 to the ALS 2. Of course, only one joint 8a may be provided for each metal piece 8, and a plurality of the joints 8a may be provided.
[0033]
As shown in FIGS. 4 and 5, the ultrasonic welder includes a tip (also referred to as a tool horn) 20, an anvil 21 opposed to the tip 20, an oscillator (not shown), a vibrator, a horn, and the like. ing. In the ultrasonic welding machine, an object to be welded is sandwiched between the tip 20 and the anvil 21, and the vibrator is vibrated by the oscillator in a state in which the tip 20 and the anvil 21 are pressurized in a direction approaching each other. Then, this vibration is transmitted to the chip 20 via the horn. Then, the ultrasonic welding machine applies ultrasonic vibration to the welding target object sandwiched between the tip 20 and the anvil 21 to weld the target object.
[0034]
When the conductor thin film with conductor 1 is manufactured, that is, when the ALS 2 and the metal piece 8 are fixed to each other, first, as shown in FIG. 4, the ALS 2 and the metal piece are placed between the chip 20 and the anvil 21. 8 part 8a is sandwiched. At this time, the ALS 2 is stacked on the anvil 21 and the metal piece 8 is brought into contact with the chip 20. Further, the conductor layer 4 is overlaid on the anvil 21 and the metal piece 8 is overlaid on the insulating layer 7.
[0035]
Then, after pressurizing the chip 20 and the anvil 21 in a direction to bring them close to each other, the vibrator is vibrated by an oscillator, and this vibration is transmitted to the chip 20 via a horn. The above-described vibration occurs between the conductive thin film sheet 2 and the metal piece 8, and first, the first insulating layer 5 and the second insulating layer 6 located in the part 8 a are melted.
[0036]
Since the tip 20 and the anvil 21 are pressurized in a direction approaching each other, when the first insulating layer 5 and the second insulating layer 6 are melted, the second portion 8a of the metal piece 8 and the conductor layer 4 are changed from the first portion. The first insulating layer 5 and the second insulating layer 6 are removed. The part 8a of the metal piece 8 and the conductor layer 4 are in contact with each other. When in contact with each other, the conductor layer 4 and the part 8a of the metal piece 8 are metal-bonded to each other in a solid phase without being melted by the vibration described above, as shown in FIG.
[0037]
That is, the conductor layer 4 and the metal piece 8 are joined to each other by so-called ultrasonic welding (also referred to as ultrasonic welding or ultrasonic bonding). The vibration of the vibrator is stopped and the chip 20 and the anvil 21 are separated from each other. If necessary, the metal piece 8 and the conductor layer 4 are ultrasonically welded in the same manner as described above. And the conductor thin film 1 with a conductor of the structure mentioned above in which the metal piece 8 overlapped with the insulating layer 7, and a part 8a joined to the conductor layer 4 is obtained.
[0038]
The conductor thin film 1 with a conductor thus obtained is wound around the outer circumference of the bundled electric wires 3 with the conductor layer 4 positioned on the inner side and the insulating layer 7 positioned on the outer side. The plurality of electric wires 3 are bundled such that a tape 15 is wound around the outer periphery. For this reason, the metal piece 8 is located outside the ALS 2.
[0039]
When the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, the ALS 2 can be wound along the metal piece 8 by plastically deforming the metal piece 8 in a ring shape. Therefore, the ALS 2 can be easily wound around the outer periphery of the electric wire 3 by plastically deforming the metal piece 8 in a ring shape. Further, the wound ALS 2 is supported by the metal piece 8.
[0040]
A double-sided tape 16 or the like is attached to the conductor layer 4 of the ALS 2 in order to fix the plurality of electric wires 3 and a part of the ALS 2 overlapping each other. The double-sided tape 16 is provided at each end of the ALS 2 in the width direction. The double-sided tape 16 has an adhesive surface on both sides.
[0041]
One double-sided tape 16 is attached to the outer peripheral surface of the electric wire 3 around which the tape 15 is wound, and the other double-sided tape 16 is attached to each part of the ALS 2 that overlaps each other. In the present invention, an adhesive may be used instead of the double-sided tape 16, or a tape having an adhesive surface formed only on one surface may be used.
[0042]
The conductor thin film 1 with a conductor having the above-described configuration electrically shields the electric wire 3 by, for example, winding the ALS 2 around the plurality of electric wires 3. And it attaches to the well-known printed wiring board 18 etc. with the screw | thread 17 etc. which pass the said through-hole 8b. Then, the metal piece 8 is electrically connected to a desired ground circuit or the like by the screw 17 and a conductor pattern (not shown) of the printed wiring board 18.
[0043]
According to this embodiment, since the conductor layer 4 and the metal piece 8 are joined to each other by ultrasonic welding, an increase in the number of parts required when attaching the metal piece 8 to the ALS 2 can be suppressed. Therefore, cost reduction of the conductor thin film 1 with a conductor can be achieved.
[0044]
When the metal piece 8 is superposed on the insulating layer 7 and ultrasonic welding is performed, and the ultrasonic welding is performed, the insulating layer 7 is removed from between the part 8 a of the metal piece 8 and the conductor layer 4. For this reason, when attaching the metal piece 8 to ALS2, it is not necessary to remove a part of the insulating layer 7 or the like. For this reason, the man-hour required when attaching the metal piece 8 to the conductor thin film sheet 2 can be suppressed. Therefore, further cost reduction of the conductor thin film 1 with a conductor can be achieved.
[0045]
Since the metal piece 8 is joined to the conductor layer 4, when the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, for example, the metal piece 8 is attached to the printed wiring board 18 with screws 17 or the like. Through the 18 conductor patterns and the like, it is possible to release the noise to enter the electric wire 3 to the outside. As described above, since the metal piece 8 is joined to the conductor layer 4, it is possible to surely escape the noise to enter the plurality of electric wires 3 to the outside through the metal piece 8. Therefore, when the conductor thin film 1 with a conductor is wound around the electric wire 3, noise can be prevented from entering the electric wire 3.
[0046]
Further, the metal piece 8 is superposed on the insulating layer 7, and a part 8 a is joined to the conductor layer 4. For this reason, it can prevent that the conductor layer 4 is damaged compared with the case where the metal piece 8 is directly joined to the conductor layer 4. Therefore, when the conductor thin film 1 with a conductor is wound around the electric wire 3, it is possible to more reliably prevent noise from entering the electric wire 3.
[0047]
Furthermore, the longitudinal direction of the metal piece 8 is along the circumferential direction of the electric wire. For this reason, the ALS 2 can be wound along the metal piece 8 by plastically deforming the metal piece 8 in a ring shape. Therefore, the ALS 2 can be easily wound around the outer periphery of the electric wire 3 by plastically deforming the metal piece 8 in a ring shape. Furthermore, the wound ALS2 is supported by the metal piece 8, and the positional deviation of the ALS2 is prevented.
[0048]
Further, the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3 with the conductor layer 4 positioned on the inner side and the insulating layer 7 positioned on the outer side. For this reason, it can prevent that the conductor layer 4 short-circuits with the electric wire or electronic device different from the said electric wire 3. FIG.
[0049]
Next, a conductor thin film with conductor according to a second embodiment of the present invention will be described with reference to FIGS. Note that the same components as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.
[0050]
In the conductor thin film 1 with conductor of the present embodiment, the metal piece 8 is overlapped with the conductor layer 4 of the ALS 2 and directly joined to the conductor layer 4 as shown in FIGS. 6 to 8. Also in this embodiment, when the ALS 2 is wound around the outer periphery of the plurality of electric wires 3, the metal piece 8 is attached to each of both end portions 2 a and 2 b of the ALS 2 that are spaced apart from each other along the longitudinal direction of the electric wires 3. The longitudinal direction is along the circumferential direction of the electric wire 3, that is, the width direction of the ALS2. Moreover, in this embodiment, the metal piece 8 is extended over the other edge part from the one edge part of the width direction of ALS2, as shown in FIG. One end of the metal piece 8 does not protrude from the edge of the ALS 2.
[0051]
When assembling the conductor thin film 1 with conductor of this embodiment, first, the ALS 2 and a part 8a of the metal piece 8 are sandwiched between the chip 20 and the anvil 21 as in the first embodiment described above. . At this time, in this embodiment, the ALS 2 is overlaid on the anvil 21, the metal piece 8 is brought into contact with the chip 20, the insulating layer 7 is overlaid on the anvil 21, and the metal piece 8 is overlaid on the conductor layer 4.
[0052]
Then, after pressurizing the chip 20 and the anvil 21 in a direction to bring them close to each other, the vibrator is vibrated by an oscillator, and this vibration is transmitted to the chip 20 via a horn. The conductor layer 4 and the part 8a of the metal piece 8 are metal-bonded to each other while being in a solid phase without being melted by the vibration described above. That is, the conductor layer 4 and the metal piece 8 are bonded to each other by so-called ultrasonic welding (also referred to as ultrasonic welding or ultrasonic bonding). Thus, the conductor thin film 1 with a conductor having the above-described configuration in which the metal piece 8 overlaps the conductor layer 4 and a part 8a is joined to the conductor layer 4 is obtained.
[0053]
As shown in FIGS. 6 and 7, the conductive thin film sheet 1 with a conductor obtained in this way has a conductor layer 4 positioned on the outer periphery of a plurality of electric wires 3 bundled with a tape 15 or the like, and an insulating layer. It is wound with 7 positioned outside. For this reason, the said metal piece 8 is located inside ALS2.
[0054]
When the ALS 2 is wound around the outer circumferences of the plurality of electric wires 3, it is desirable that the metal piece 8 be plastically deformed into a ring shape, as in the first embodiment. The ALS 2 can be wound along the metal piece 8 by plastically deforming the metal piece 8 in a ring shape. Therefore, the ALS 2 can be easily wound around the outer periphery of the electric wire 3 by plastically deforming the metal piece 8 in a ring shape.
[0055]
Further, when the ALS 2 is fixed to the outer periphery of the electric wire 3 and a part of the ALS 2 that is overlapped with each other is fixed, the double-sided tape 16 or the like is used as in the first embodiment described above. The double-sided tape 16 is of course affixed to the conductor layer 4 and is provided at each of both end portions of the ALS 2 in the width direction.
[0056]
The conductor thin film 1 with a conductor having the above-described configuration electrically shields the electric wire 3 by, for example, winding the ALS 2 around the plurality of electric wires 3. Moreover, when the said electric wire 3 connects the some auxiliary machine 9 mutually, as shown in FIG.9 and FIG.10, the inside of the pipe part 19 of this auxiliary machine 9 is passed. Of course, these tube portions 19 are formed in a circular tube shape and are made of a conductive metal or the like.
[0057]
When the electric wire 3 is passed through the pipe portions 19 of the plurality of auxiliary machines 9, the conductor thin film 1 with conductor passes through the pipe portion 19 inside the metal piece 8 that is plastically deformed into a ring shape. The pipe part 19, that is, the auxiliary machine 9 is attached by the metal band 22. The metal band 22 is made of a conductive metal and has an annular shape.
[0058]
The metal band 22 is provided with a pair of operation claws 23 protruding outward. By narrowing or widening the distance between the operation claws 23, the inner and outer diameters can be expanded and contracted. ing. The metal band 22 is elastically deformable so that the inner and outer diameters expand and contract. As shown in FIG. 9, the metal band 22 is a conductor wound around the outer circumferences of the plurality of electric wires 3 with the inner and outer diameters extended by narrowing the interval between the operation claws 23 or the like. The attached conductor thin film sheet 1 is passed.
[0059]
Then, the metal band 22 generates an elastic restoring force so that the distance between the operation claws 23 returns to the initial state, the inner and outer diameters are reduced, and the metal piece 8 of the conductor thin film 1 with conductor is attached to the tube portion 19. Press against the outer surface. In this way, the conductor thin film 1 with a conductor is fixed to the pipe portion 19, that is, the auxiliary machine 9 by the metal band 22 as shown in FIG. 10.
[0060]
When the conductor thin film 1 with conductor is fixed to the tube portion 19 by the metal band 22, the metal piece 8 is in close contact with the outer peripheral surface of the tube portion 19 as shown in FIG. The metal piece 8 is electrically connected to the tube portion 19 and the like.
[0061]
According to this embodiment, since the conductor layer 4 and the metal piece 8 are joined by ultrasonic welding as in the first embodiment described above, the man-hours and parts required when attaching the metal piece 8 to the ALS 2 The increase in points can be suppressed. Therefore, cost reduction of the conductor thin film 1 with a conductor can be achieved.
[0062]
Moreover, the longitudinal direction of the metal piece 8 is along the circumferential direction of the electric wire. For this reason, the ALS 2 can be wound along the metal piece 8 by plastically deforming the metal piece 8 in a ring shape. Therefore, the ALS 2 can be easily wound around the outer periphery of the electric wire 3 by plastically deforming the metal piece 8 in a ring shape. Further, the wound ALS 2 is supported by the metal piece 8. For this reason, the position shift of ALS2 can be prevented.
[0063]
Further, the metal piece 8 is attached to both end portions 2 a and 2 b of the ALS 2 which are spaced along the longitudinal direction of the electric wire 3. For this reason, the metal piece 8 can be easily fixed to the auxiliary machine 9 through the pipe portion 19 inside the metal piece 8 by plastic deformation in a ring shape. Further, the metal piece 8 can be securely fixed to the pipe portion 19 by fastening with the metal band 22 or the like from the outside. For this reason, the noise which is going to enter the plurality of electric wires 3 can be surely released to the outside through the metal piece 8 and the pipe portion 19. Therefore, noise can be prevented from entering the electric wire 3 more reliably.
[0064]
Similarly to the first embodiment described above, when the wire 3 is wound around the outer periphery of the electric wire 3, the conductor layer 4 is located on the inner side and the insulating layer 7 is located on the outer side. For this reason, it can prevent that the conductor layer 4 short-circuits with the electric wire or electronic device different from the said electric wire 3. FIG.
[0065]
