[Embodiment]
Embodiments of the present invention will be described below with reference to the accompanying drawings.

(Description of vehicle to which the cable is applied)
FIG. 1 is a block diagram showing a configuration of a vehicle using the cable according to the present embodiment.

As shown in FIG. 1, a vehicle 100 is provided with an electric parking brake (hereinafter referred to as EPB) 101 as an electric braking device.

The EPB 101 includes an EPB electric motor 101a and an EPB control unit 101b.

The EPB electric motor 101a is a wheel side device mounted on the wheel 102 of the vehicle 100. The EPB control unit 101b is mounted on an ECU (electronic control unit) 103 which is a vehicle body side device of the vehicle 100. The EPB control unit 101b may be mounted on a control unit other than the ECU 103, or may be mounted on a dedicated hardware unit.

Although not shown, the EPB electric motor 101a is provided with a piston to which a brake pad is attached, and by moving the piston by rotationally driving the EPB electric motor 101a, the brake pad of the wheel 102 is moved. The wheel is pressed against the disk rotor to generate a braking force. A pair of first electric wires 2 is connected to the EPB electric motor 101a as a power supply line for supplying a drive current to the EPB electric motor 101a.

The EPB control unit 101b outputs a drive current to the EPB electric motor 101a for a predetermined time (for example, 1 second) when the parking brake operation switch 101c is operated from the off state to the on state when the vehicle 100 is stopped. The brake pad is pressed against the disc rotor of the wheel 102 to generate a braking force on the wheel 102. Further, the EPB control unit 101b outputs a drive current to the EPB electric motor 101a when the parking brake actuation switch 101c is operated from the ON state to the OFF state, or when the accelerator pedal is stepped on, so that the brake is applied. The pad is spaced from the disc rotor of the wheel to release the braking force on the wheel 102. That is, the operation state of the EPB 101 is configured to be maintained after the parking brake operation switch 101c is turned on until the parking brake operation switch 101c is turned off or the accelerator pedal is depressed. The parking brake operation switch 101c may be a lever type switch or a pedal type switch.

An ABS device 104 is mounted on the vehicle 100. The ABS device 104 includes an ABS sensor 104a and an ABS control unit 104b.

The ABS sensor 104a is a rotation speed detection sensor that detects the rotation speed of the wheel 102 during traveling, and is mounted on the wheel 102. The ABS control unit 104b controls the braking device based on the output of the ABS sensor 104a and controls the braking force of the wheels 102 so that the wheels 102 are not locked during a sudden stop, and is installed in the ECU 103. The twisted pair wire 4 (a pair of second electric wires 3) is connected to the ABS sensor 104a as a signal wire.

The cable 1 according to the present embodiment is formed by covering the pair of first electric wires 2 and the twisted wires 4 together with the sheath 7 (see FIG. 2 ). The cable 1 extending from the wheel 102 side is connected to a wire group 107 in a relay box 106 provided in the vehicle body 105, and is connected to the ECU 103 and a battery (not shown) via the wire group 107.

Although only one wheel 102 is shown in FIG. 1 for simplification of the drawing, the EPB electric motor 101a and the ABS sensor 104a may be mounted on each wheel 102 of the vehicle 100. The vehicle 100 may be mounted only on the front wheels or only on the rear wheels.

(Explanation of cable 1)
FIG. 2A is a cross-sectional view of the cable 1 according to the present embodiment, and FIG. 2B is a diagram illustrating a twisting direction of a twisted pair wire, a twisting direction of an assembly, and a winding direction of a tape member. is there.

As shown in FIGS. 2A and 2B, the cable 1 is spirally wound around a plurality of electric wires 2 and 3 and an assembly 5 formed by twisting the plurality of electric wires 2 and 3. The tape member 6 and the sheath 7 covering the outer periphery of the tape member 6 are provided.

In the present embodiment, the plurality of electric wires 2 and 3 are formed by twisting a pair of first electric wires 2 and a pair of second electric wires 3 having an outer diameter smaller than that of the first electric wires 2 in the circumferential direction. And a twisted pair wire 4 disposed between the pair of first electric wires 2. The aggregate 5 is formed by twisting a pair of first electric wires 2 and twisted pair wires 4.

The first electric wire 2 includes a first conductor 21 and a first insulator 22 that covers the outer circumference of the first conductor 21. The first conductor 21 is made of a stranded wire conductor in which strands having good conductivity such as copper are twisted together, and the first insulator 22 is made of an insulating resin such as crosslinked polyethylene. As a wire used for the first conductor 21, a wire having a diameter of 0.05 mm or more and 0.30 mm or less can be used. If a wire with a diameter of less than 0.05 mm is used, sufficient mechanical strength may not be obtained and flex resistance may decrease. If a wire with a diameter of more than 0.30 mm is used, the flexibility of the cable 1 May decrease.

The second electric wire 3 includes a second conductor 31 and a second insulator 32 that covers the outer periphery of the second conductor 31. The second conductor 31 is made of a stranded wire conductor in which strands of good conductivity such as copper are twisted together, and the second insulator 32 is made of an insulating resin such as cross-linked polyethylene. As the element wire used for the second conductor 31, a wire having a diameter of 0.05 mm or more and 0.30 mm or less can be used, like the first conductor 21.

In the present embodiment, the first electric wire 2 is a power supply line for supplying a drive current to the EPB electric motor 101a mounted on the wheels 102 of the vehicle 100. Further, in the present embodiment, the second electric wire 3 is a signal wire for the ABS sensor 104a mounted on the wheel 102.

The cross-sectional area (conductor cross-sectional area) of the first conductor 21 of the first electric wire 2 and the thickness of the first insulator 22 may be appropriately set according to the magnitude of the required drive current. In the present embodiment, since the first electric wire 2 is used as the power supply line and the second electric wire 3 is used as the signal line, the first conductor 21 has a cross sectional area (conductor cross sectional area) larger than that of the second conductor 31. It is set large. In the present embodiment, considering that the first electric wire 2 is a power supply wire for supplying a drive current to the EPB electric motor 101a, the outer diameter of the first conductor 21 is set to 1.5 mm or more and 3.0 mm or less. In addition to the setting, the outer diameter of the first electric wire 2 was set to 2.0 mm or more and 4.0 mm or less.

The second electric wire 3 has a smaller outer diameter than the first electric wire 2. In other words, the outer diameter of the first electric wire 2 is larger than the outer diameter of the second electric wire 3. In the present embodiment, since a pair 5 of twisted paired wires 4 formed by twisting a pair of (2) second electric wires 3 and a pair of first electric wires 2 are twisted together to form an assembly 5, From the viewpoint of making the outer diameter close to a circular shape, it can be said that it is desirable to use, as the second electric wire 3, one that is about half the outer diameter of the first electric wire 2. Specifically, the second electric wire 3 may have an outer diameter of 1.0 mm or more and 1.8 mm or less. Here, as the second electric wire 3, a conductor having a conductor cross-sectional area of the second conductor 31 of 0.13 mm ² or more and 0.30 mm ² or less was used.

The twist pitch P1 of the twisted pair wire 4 is preferably set in consideration of the outer diameter of the second electric wire 3 so that an unnecessary load is not applied to the second electric wire 3. Here, the twist pitch P1 of the twisted pair wire 4 is about 30 mm, but the twist pitch P1 of the twisted pair wire 4 is not limited to this. The twist pitch P1 of the twisted pair wire 4 is an interval along the longitudinal direction of the twisted pair wire 4 where any second electric wire 3 is located at the same position in the circumferential direction of the twisted pair wire 4.

The aggregate 5 is formed by twisting a pair of first electric wires 2 and a twisted pair wire 4. In the present embodiment, the twisted pair wire 4 is arranged between the pair of first electric wires 2 in the circumferential direction. In the cross section of FIG. 2A, one first electric wire 2, the other first electric wire 2, and the twisted pair wire 4 are sequentially arranged in the clockwise direction. The twisted pair wire 4 is arranged so as to enter the valley portion between the pair of first electric wires 2.

Although not shown in FIG. 2, a plurality of thread-like (fiber-like) inclusions extending in the longitudinal direction of the cable 1 are arranged between the pair of first electric wires 2, twisted wires 4, and tape members 6, The assembly 5 may be configured by twisting a plurality of inclusions, the pair of first electric wires 2, and the twisted pair wire 4 together. By arranging the inclusions so as to fill the gaps between the one electric wire 2, the twisted pair wire 4, and the tape member 6, the cross-sectional shape when the tape member 6 is wound around the outer periphery of the assembly 5 becomes more circular. You can get closer. A part of the plurality of inclusions may be arranged in a valley between the first electric wire 2 and the twisted pair wire 4 or in a valley between the pair of first electric wires 2. As the inclusions, polypropylene yarn, soft yarn (rayon staple fiber), aramid fiber, nylon fiber, fibrous material such as fiber-based plastic, or paper or cotton yarn can be used.

The EPB 101 basically supplies a drive current to the electric motor 101a when the vehicle is stopped. On the other hand, the ABS sensor 104a is used when the vehicle is traveling, and the ABS sensor 104a is not used when the drive current is supplied to the first electric wire 2. Therefore, in the present embodiment, the shield conductor provided around each of the electric wires 2 and 3 or the twisted pair wire 4 is omitted. By omitting the shield conductor, the outer diameter of the cable 1 can be reduced as compared with the case where the shield conductor is provided, and the number of parts can be reduced to reduce the cost.

Although the case where the first electric wire 2 supplies the drive current to the EPB electric motor 101a is described here, the first electric wire 2 may be, for example, an electromechanical brake (hereinafter referred to as an EMB) provided on the wheel 102. May be used to supply a drive current to the electric motor). In this case, since a current flows through the first electric wire 2 while the vehicle 100 is traveling, in order to suppress malfunction of the ABS device 104 due to noise, the surroundings of the first electric wire 2 or the twisted pair 4 ( It can be said that it is desirable to provide a shield conductor around the second electric wire 3.

Further, although the case where the second electric wire 3 is a signal wire for the ABS sensor 104a is described here, the second electric wire 3 detects another sensor provided on the wheel 102, for example, a temperature sensor or a tire air pressure. A signal line used for an air pressure sensor or the like, a damper line used for controlling a vibration damping device of the vehicle 100, or a signal line for EMB control (CAN cable or the like). May be. Even when the first electric wire 2 supplies a drive current to the electric motor 101a for EPB, when the second electric wire 3 is used while the vehicle 100 is stopped, the malfunction due to noise is suppressed. In addition, it can be said that it is desirable to provide the shield conductor around the first electric wire 2 or around the twisted pair wire 4 (around the second electric wire 3).

The outer diameter of the entire assembly 5 is, for example, about 5 mm to 9 mm. The twist pitch P2 of the assembly 5 may be set in consideration of the outer diameter of the assembly 5 so that an unnecessary load is not applied to the first electric wire 2 and the twisted pair wire 4. Here, the twist pitch P2 of the aggregate 5 is set to about 60 mm, but the twist pitch P2 of the aggregate 5 is not limited to this. The twist pitch P2 of the assembly 5 is a distance along the longitudinal direction of the assembly 5 in which any first electric wire 2 or twisted pair wire 4 is located at the same position in the circumferential direction of the assembly 5.

A tape member 6 is spirally wound around the assembly 5, and the outer periphery of the tape member 6 is covered with a sheath 7. The sheath 7 is made of urethane resin, for example. Here, a urethane resin having a thickness of 0.8 mm is used as the sheath 7. In the present embodiment, the first electric wire 2 supplies the driving current to the EPB electric motor 101a, and the driving current flows through the first electric wire 2 for a relatively short time. Therefore, the first electric wire 2 is provided around the tape member 6. Although the shield conductor is omitted, a shield conductor may be provided between the tape member 6 and the sheath 7 or on the outer periphery of the sheath 7 depending on the application of the first electric wire 2.

(Explanation of the tape member 6)
The tape member 6 is spirally wound around the assembly 5 and is in contact with all the electric wires 2 and 3 covered by the tape member 6. The tape member 6 is interposed between the assembly 5 and the sheath 7, and plays a role of reducing friction between the assembly 5 (electric wires 2 and 3) and the sheath 7 when bent. That is, by providing the tape member 6, the friction between the electric wires 2 and 3 and the sheath 7 is reduced without using a lubricant such as talc powder as in the conventional case, and the stress applied to the electric wires 2 and 3 at the time of bending is reduced. It becomes possible to reduce the bending resistance and improve the bending resistance.

The tape member 6 is spirally wound around the assembly 5 in a state where tension is applied. Therefore, it is necessary to use the tape member 6 that does not break due to the tension applied during winding. On the other hand, the tape member 6 is to be removed together with the sheath 7 during the end processing. Therefore, it is desirable to use, as the tape member 6, one that can be easily removed at the time of terminal processing.

Therefore, in the present embodiment, as the tape member 6, a tape member having different tensile strengths in the longitudinal direction and the width direction and having a tensile strength in the width direction smaller than that in the longitudinal direction is used.

By using a tape member 6 having a large tensile strength in the longitudinal direction, breakage of the tape member 6 when the tape member 6 is wound around the assembly 5 can be suppressed. Specifically, the tensile strength of the tape member 6 in the longitudinal direction is preferably 120 MPa or more.

Further, by using the tape member 6 having a small tensile strength in the width direction, the tape member 6 is easily broken at the time of terminal processing, and the tape member 6 can be easily removed when the sheath 7 is removed. The workability of strip work is improved.

The tensile strength in the width direction of the tape member 6 is preferably 2/3 or less of the tensile strength in the longitudinal direction. More specifically, the tensile strength of the tape member 6 in the width direction is preferably 15 MPa or more and 80 MPa or less. If the tensile strength of the tape member 6 in the width direction is less than 15 MPa, the tape member 6 is easily torn, and thus it becomes difficult to handle, and the tape member 6 may be torn due to a load during bending. Further, when the tensile strength of the tape member 6 in the width direction exceeds 80 MPa, it becomes difficult to remove the tape member 6 at the time of terminal processing, and the workability of strip work is deteriorated.

Further, the thickness of the tape member 6 is preferably 0.028 mm or more and 0.090 mm or less. When the thickness of the tape member 6 is 0.028 mm or more, the tensile strength in the longitudinal direction cannot be secured and the tape member 6 is easily broken at the time of winding. When the thickness of the tape member 6 exceeds 0.090 mm, the tape member 6 is This is because it may be difficult to tear and the strip work may become difficult.

The width of the tape member 6 is preferably 18 mm or more and 35 mm or less. When the width of the tape member 6 is less than 18 mm, the tensile strength in the longitudinal direction cannot be ensured and the tape member 6 is easily broken at the time of winding. When the width of the tape member 6 exceeds 35 mm, the tape member 6 is used as a jig ( This is because it is necessary to secure a wide area to be cut by a blade or the like, which may reduce workability of stripping work.

Further, it is desirable that the width of the tape member 6 be such that the tape member 6 is not wrinkled when the tape member 6 is wound, and the tape member is narrower as the overall outer diameter of the assembly 5 is smaller. It is desirable to use 6. In this embodiment, since the outer diameter of the aggregate 5 is 5 mm to 9 mm, the width of the tape member 6 capable of suppressing the generation of wrinkles is about 50 mm at the maximum. That is, by setting the width of the tape member 6 to be 18 mm or more and 35 mm or less, it is possible to suppress wrinkles from occurring on the tape member 6 during winding.

The tape member 6 is spirally wound around the assembly 5 so that a part of the tape member 6 in the width direction (direction perpendicular to the longitudinal direction and the thickness direction of the tape member 6) overlaps with each other. In the present embodiment, the tape member 6 is spirally wound with an overlapping width of 1/4 or more and 1/2 or less of its width. If the overlapping width of the tape members 6 exceeds 1/2, a portion where the tape members 6 overlap with each other becomes triple or more, and stripping work becomes difficult. Therefore, the overlapping width of the tape members 6 needs to be at least 1/2 or less. There is. In the present embodiment, the overlapping portions of the tape members 6 are not adhered by an adhesive or the like.

Further, in the present embodiment, the tape member 6 is wound around the assembly 5 with an inclination of 30° or more and 60° or less with respect to the cable longitudinal direction. Hereinafter, the angle at which the tape member 6 is inclined with respect to the cable longitudinal direction (when an arbitrary portion in the longitudinal direction of the tape member 6 is viewed from the outside in the radial direction, the longitudinal direction of the tape member 6 and the cable longitudinal direction The angle formed by the direction) is called the winding angle of the tape member 6. When the winding angle of the tape member 6 is less than 30°, the tape member 6 is close to the vertically laid state, so that the flexibility of the cable 1 is lost and it becomes difficult to bend, and the tape member 6 is pulled and pulled at the time of stripping. Since it is necessary to pull the tape member 6 in the longitudinal direction to break the tape member 6, the tape member 6 is less likely to be broken, and the workability of the strip work is reduced. When the winding angle of the tape member 6 exceeds 60°, the number of windings of the tape member 6 increases and the overlapping width of the tape member 6 also increases, which makes it difficult to remove the tape member 6 during stripping work. Wrinkles are more likely to occur. The winding angle of the tape member 6 can be adjusted by the width and the overlapping width of the tape member 6.

The winding pitch P3 of the tape member 6, that is, the distance along the longitudinal direction of the cable 1 where the tape member 6 is at the same position in the circumferential direction (for example, the distance between the one ends in the width direction) is the width and the overlapping width of the tape member 6. It depends on (the winding angle of the tape member 6), and in this case, the maximum is about 40 mm. Although the winding pitch P3 of the tape member 6 is about 30 mm here, the winding pitch P3 of the tape member 6 is not limited to this. When the winding pitch P3 of the tape member 6 is increased, the tape member 6 becomes closer to a vertically attached state, which may reduce flexibility and workability of strip work. The winding pitch P3 is preferably 40 mm or less.

Further, the tape member 6 can reduce the unnecessary stress of the electric wires 2 and 3 at the time of bending with respect to the first insulator 22 of the first electric wire 2 and the second insulator 32 of the second electric wire 3. It is desirable to use a slippery material (having a small friction coefficient). More specifically, the tape member 6 has a friction coefficient (static friction coefficient) between the tape member 6 and the insulators 22 and 32 between the sheath 7 and the insulators 22 and 32 when the tape member 6 is not provided. It is preferable to use a member having a smaller coefficient of friction (coefficient of static friction).

In the cable 1 according to the present embodiment, the tape member 6 has different surface roughness between the surface on the assembly 5 side and the surface on the sheath 7 side, and the surface roughness on the surface on the sheath 7 side is the same as the assembly 5 side. The surface roughness is larger than that of the surface (larger surface roughness).

By roughening the surface of the tape member 6 on the side of the assembly 5, the resin forming the sheath 7 enters the minute irregularities on the surface of the tape member 6 on the assembly 5 side, and the tape member 6 and the sheath 7 are separated by the anchor effect. The adhesiveness of is improved. As a result, during the stripping operation for removing the sheath 7, it becomes easy to remove the sheath 7 and the tape member 6 once (integrally) without separating them, and the workability of the stripping operation is improved.

Further, by reducing the surface roughness of the surface of the tape member 6 on the side of the assembly 5, the assembly 5 becomes slippery with respect to the tape member 6, so that the stress applied to the electric wires 2 and 3 during bending is suppressed. Flexibility can be improved. Furthermore, since the assembly 5 becomes slippery with respect to the tape member 6, the sheath 7 and the tape member 6 are easily pulled out from the assembly 5 during the stripping work, and the workability of the stripping work is further improved.

As the tape member 6, for example, non-woven fabric, paper such as Japanese paper, or resin (resin film) can be used.

When a non-woven fabric is used as the tape member 6, it is desirable to use a non-woven fabric made of polyester, polypropylene, aramid fiber, nylon, acrylic fiber, or glass fiber. This makes it difficult for the tape member 6 to absorb moisture, and it is possible to suppress the evaporation of water from the tape member 6 and the foaming of the sheath 7 due to the heat when the sheath 7 is covered. Further, when a non-woven fabric is used as the tape member 6, it is desirable to use one having air permeability of 30 cc/cm ² /sec or more and 200 cc/cm ² /sec or less. This is because when the air permeability is as low as less than 30 cc/cm ² /sec, the air containing water vapor easily accumulates in the space covered with the tape member 6, and the air accumulated by the heat when the sheath 7 is covered. This is because there is a risk that the non-woven fabric may be discharged all at once from the voids of the nonwoven fabric or the portions where the tape members 6 are overlapped, and the sheath 7 may be foamed. Further, if the air permeability becomes greater than 200 cc/cm ² /sec, a part of the sheath 7 penetrates the tape member 6 and reaches the electric wires 2 and 3 when covering the electric wire 2. , 3 and the sheath 7 may be fused and the workability at the time of terminal treatment may be reduced.

Further, as the tape member 6, it is also possible to use one formed by laminating two or more layers of different materials in the thickness direction, that is, one having a laminated structure of two or more layers. In this case, the surface of the tape member 6 that comes into contact with the aggregate 5 may be made of a non-woven fabric, paper, or a resin layer. For example, as the tape member 6, a paper having a resin layer made of PET (polyethylene terephthalate) or the like formed on one surface of paper is used, and the resin layer having a smaller friction coefficient may be wound around the assembly 5 side. it can.

Further, an adhesive layer is provided on the surface of the tape member 6 on the sheath 7 side, which is adhered to the surface on the sheath 7 side by laminating or the like, and which is melted by heat when the sheath 7 is covered and welded to the sheath 7. Good. As a result, the tape member 6 and the sheath 7 are less likely to be separated from each other, so that workability of the stripping work is further improved. The adhesive layer is provided integrally with the tape member 6, but in the present embodiment, the adhesive layer is treated as a member different from the tape member 6. That is, when the adhesive layer is provided, the surface of the tape member 6 on the sheath 7 side means not the surface of the adhesive layer but the surface to which the adhesive layer is bonded. When the adhesive layer is provided, the surface roughness of the surface of the tape member 6 on the sheath 7 side may be the same as the surface roughness of the surface on the assembly 5 side.

(Twisting direction of the twisted pair wire 4 and the assembly 5, winding direction of the tape member 6)
In the cable 1 according to the present embodiment, the twisting direction of the twisted pair wire 4 and the twisting direction of the assembly 5 are different, and the twisting direction of the assembly 5 and the winding direction of the tape member 6 are different. .. That is, in the cable 1, the twisting direction of the twisted pair wire 4 and the winding direction of the tape member 6 are the same, and only the twisting direction of the aggregate 5 is different.

The twisting direction of the twisted pair wire 4 as used herein means the second wire 3 when the cable 1 is viewed from the tip side (the left side in FIG. 2B, the side where the tape member 6 overlaps). Refers to the direction in which the twisted pair 4 rotates in the circumferential direction from the base end side to the tip end side. The twisting direction of the assembly 5 refers to the twisted pair wire 4 and the first electric wire when the cable 1 is viewed from the tip end side (the left side in FIG. 2B, the side where the tape member 6 overlaps). 2 refers to the direction in which the assembly 5 rotates in the circumferential direction from the base end side to the tip end side. Here, the twisting direction of the twisted pair wire 4 is clockwise (clockwise), and the twisting direction of the assembly 5 is counterclockwise (counterclockwise).

In addition, the winding direction of the tape member 6 means that when the cable 1 is viewed from the distal end side (the left side in FIG. 2B, the side where the tape member 6 overlaps), the tape member 6 extends from the proximal end side to the distal end side. It is the direction of rotation to the side. Here, the winding direction of the tape member 6 is clockwise (clockwise). FIG. 2A shows a cross-sectional view as seen from the tip side, in which the twisting direction of the twisted pair wire 4 is indicated by a broken arrow A, the twisting direction of the assembly 5 is indicated by a broken arrow B, and the winding direction of the tape member 6. Is indicated by a dashed arrow C.

In general, when the electric wires are twisted together or the tape is wound in a spiral shape, a bending tendency is imparted depending on the twisting direction and the winding direction, and the entire cable is naturally curved. In the present embodiment, the twisting direction of the twisted pair wire 4 and the twisting direction of the aggregate 5 are made different, and the twisting direction of the aggregate 5 and the winding direction of the tape member 6 are made different. The bending habit of the wire 4 and the bending habit of the aggregate 5 are opposite to each other and cancel each other out, and the bending habit of the aggregate 5 and the bending habit due to winding the tape member 6 are opposite to each other to cancel each other. As a result, the linear cable 1 in which the bending tendency is suppressed can be easily realized. As a result, it is possible to suppress variations in the bending characteristics of the cable 1 in the longitudinal direction.

Further, when the twisting direction of the twisted pair wire 4 and the twisting direction of the aggregate 5 are the same, the twisted pair wire 4 is twisted in a direction in which the twisting is tightened when the aggregates 5 are twisted together. The twist pitch P1 may change. By making the twisting direction of the twisted pair wire 4 different from the twisting direction of the aggregate 5, it is possible to form the aggregate 5 while suppressing a change in the twisting pitch P1 of the twisted pair wire 4.

However, if the twisting pitch P1 of the twisted pair wire 4 is large, the twisting of the twisted pair wire 4 may become loose when the assembly 5 is twisted together. Therefore, it is desirable that the twist pitch P1 of the twisted pair wire 4 be at least smaller than the twist pitch P2 of the aggregate 5. That is, when the twisting direction of the twisted pair wire 4 and the twisting direction of the aggregate 5 are different, the twisting pitch P1 of the twisted pair wire 4 is made smaller than the twisting pitch P2 of the aggregate 5 to make the twisted pair wire 4 The twisting of the aggregate is less likely to be broken, and the sectional shape of the aggregate 5 can be stabilized.

In the present embodiment, since the curl habit of the assembly 5 is corrected by the curl habit caused by winding the tape member 6, it is necessary to make the winding pitch P3 of the tape member 6 small enough to impart the curl habit. is there. Therefore, it is desirable that the winding pitch P3 of the tape member 6 be smaller than at least the twist pitch P2 of the aggregate 5. In the present embodiment, the twist pitch P1 of the twisted pair wire 4 is about 30 mm, the twist pitch P2 of the assembly 5 is about 60 mm, and the winding pitch P3 of the tape member 6 is about 30 mm.

Further, the winding pitch P3 of the tape member 6 may be set to be the twist pitch P1 of the twisted pair wire 4 or more. By doing so, the distortion of the tape member 6 in the portion in contact with the twisted pair wire 4 can be reduced, and the cross-sectional shape of the cable 1 can be easily formed into a circular shape.

When the winding pitch P3 of the tape member 6 is smaller than the twisting pitch P1 of the twisted pair wire 4, when the cable 1 is bent, the tape member 6 having a small winding pitch P3 expands and contracts in the longitudinal direction to reduce the load due to bending. The load due to bending is concentrated on the twisted pair wire 4 which is difficult to receive and has a large twist pitch P1 and is difficult to expand and contract in the longitudinal direction. By setting the winding pitch P3 of the tape member 6 to be equal to or larger than the twist pitch P1 of the twisted pair wire 4, a part of the load due to bending is burdened on the tape member 6, and the load due to bending is concentrated on the twisted pair wire 4. This can be suppressed and the bending durability can be improved.

Further, by making the twisting direction of the assembly 5 different from the winding direction of the tape member 6, the twist pitch P2 of the assembly 5 is less likely to change when the tape member 6 is wound, and the twist pitch P2 of the assembly 5 is less likely to change. Can be stabilized.

Furthermore, by making the twisting direction of the assembly 5 different from the winding direction of the tape member 6, the tape member 6 causes a gap between the twisted pair wire 4 and the first electric wire 2 or between the pair of first electric wires 2. It is possible to prevent the cable 1 from entering, and to make the cross-sectional shape of the cable 1 closer to a circular shape. As a result, the appearance of the cable 1 can be improved and the stripping operation for removing the sheath 7 can be easily performed. As described above, since the bending tendency of the cable 1 is suppressed, the stripping operation for removing the sheath 7 is easier.

Furthermore, by making the twisting direction of the assembly 5 different from the winding direction of the tape member 6, the direction in which the assembly 5 easily buckles and the direction in which the tape member 6 easily buckles can be made different. Even when the twisting and the bending are simultaneously applied to the cable 1, the cable 1 that is difficult to buckle can be realized.

(Explanation of wire harness using cable 1)
FIG. 3 is a schematic configuration diagram of the wire harness according to the present embodiment.

As shown in FIG. 3, the wire harness 10 includes the cable 1 according to the present embodiment and a connector attached to at least one of the ends of the electric wires 2 and 3. It

In FIG. 3, the left side in the figure shows the end on the wheel 102 side, and the right side in the figure shows the end on the vehicle body 105 side (the relay box 106 side). In the following description, the wheel 102 side end of the wire harness 10 is referred to as “one end”, and the vehicle body 105 side (relay box 106 side) end is referred to as “the other end”.

A wheel-side power supply connector 11a for connection with the EPB electric motor 101a is attached to one end of the pair of first electric wires 2, and a relay box 106 is attached to the other end of the pair of first electric wires 2. A vehicle body side power supply connector 11b for connection with the electric wire group 107 therein is attached.

The ABS sensor 104a is attached to one end of the pair of second electric wires 3 (twisted wire 4), and the inside of the relay box 106 is attached to the other end of the pair of second electric wires 3 (twisted wire 4). The vehicle body side ABS connector 12 for connection with the electric wire group 107 in FIG.

Here, the case where the first electric wire 2 and the second electric wire 3 (twisted wire 4) are individually provided with connectors has been described, but a dedicated connector for collectively connecting both electric wires 2 and 3 should be provided. It doesn't matter.

(Operation and Effect of Embodiment)
As described above, the cable 1 according to the present embodiment includes the tape member 6 that is spirally wound around the assembly 5, and the thickness of the tape member 6 is 0.028 mm or more and 0.090 mm or less. The tape member 6 has a width of 18 mm or more and 35 mm or less, and the tape member 6 is spirally wound with an overlapping width of ¼ or more and ½ or less of the width. And the tensile strength in the width direction is different, and the tensile strength in the width direction of the tape member 6 is smaller than the tensile strength in the longitudinal direction.

By providing the tape member 6, the friction between the electric wires 2 and 3 and the sheath 7 can be reduced without using a lubricant such as talc powder, and the stress applied to the electric wires 2 and 3 at the time of bending can be reduced to prevent bending. It becomes possible to improve the property. That is, according to the present embodiment, it is possible to suppress deterioration of the work environment for terminal processing while maintaining bending durability.

The thickness of the tape member 6 is 0.028 mm or more and 0.090 mm or less, the width of the tape member 6 is 18 mm or more and 35 mm or less, and the overlapping width of the tape member 6 is 1/4 or more and 1/2 or less of the tape width, and By making the tensile strength in the width direction of the tape member 6 smaller than the tensile strength in the longitudinal direction, it is possible to prevent the tape member 6 from being broken when the tape member 6 is wound, and at the same time, to tape the terminal member during processing. The member 6 can be easily broken, and the workability of the strip work for removing the sheath 7 and the tape member 6 can be improved.

Further, in the cable 1, since the twisting direction of the twisted pair wire 4 and the twisting direction of the assembly 5 are different, and the twisting direction of the assembly 5 and the winding direction of the tape member 6 are different, twisting It becomes possible to suppress the bending tendency due to the winding of the tape member 6 and to stabilize the twist pitches P1 and P2 of the twisted pair wire 4 and the assembly 5. As a result, it is possible to suppress variations in bending characteristics, and it is possible to realize the cable 1 which has stable longitudinal flexibility and is easy to route. Further, since the cross-sectional shape of the cable 1 can be made closer to a circular shape, the strip work becomes easier.

(Other embodiments)
The cable 1a shown in FIGS. 4(a) and 4(b) is the same as the cable 1 in FIG. 2, but further includes a second twisted pair wire 9 in which a pair of third electric wires 8 are twisted together.

The third electric wire 8 may be, for example, a signal wire used for a temperature sensor, an air pressure sensor for detecting tire air pressure, or the like, or a damper wire used for controlling the vibration damping device of the vehicle 100. Further, it may be a signal line (CAN cable or the like) for EMB control.

The third electric wire 8 includes a third conductor 81 and a third insulator 82 that covers the outer periphery of the third conductor 81. The third conductor 81 is made of a stranded wire conductor in which strands of good conductivity such as copper are twisted together, and the third insulator 82 is made of an insulating resin such as crosslinked polyethylene. As the element wire used for the third conductor 81, similarly to the first conductor 21, a wire having a diameter of 0.05 mm or more and 0.30 mm or less can be used.

The outer diameter of the third electric wire 8 is smaller than that of the first electric wire 2. From the viewpoint of making the outer diameter of the cable 1a close to a circular shape, it is desirable to use, as the third electric wire 8, one that is about half the outer diameter of the first electric wire 2, for example, the outer diameter. It is possible to use one having a thickness of 1.0 mm or more and 1.8 mm or less.

Here, as the third electric wire 8, a conductor having a conductor cross-sectional area of the third conductor 81 of 0.30 mm ² or more and 0.50 mm ² or less was used. As described above, since the conductor cross-sectional area of the second conductor 31 is 0.13 mm ² or more 0.30 mm ² or less, the cable 1a, the conductor cross-sectional area of the third electric wire 8 than the conductor cross-sectional area of the second wire 3 It means that it is set to be large. However, the conductor cross-sectional areas of the second electric wire 3 and the third electric wire 8 may be the same. From the viewpoint of making the cross-sectional shape of the cable 1a closer to a circular shape, the outer diameters of the second electric wire 3 and the third electric wire 8 should be made substantially equal (for example, It can be said that the difference is preferably within 20% of the outer diameter of the second electric wire 3.

The twisting direction of the second twisted pair wire 9 is the same as the twisting direction of the twisted pair wire 4. The twisting direction of the second twisted pair wire 9 means that when the cable 1a is viewed from the tip end side (the left side in FIG. 4B, the side where the tape members 6 are overlapped with each other). The direction in which the second twisted pair 9 rotates in the circumferential direction from the base end side to the tip end side. In the cable 1a, the twisting direction of the second twisted pair wire 9 is different from the twisting direction of the assembly 5 and is the same as the winding direction of the tape member 6, as shown by the dashed arrow D in FIG. 4(a). Becomes

The twist pitch P4 of the second twisted pair wire 9 is set to be substantially the same as the twist pitch P1 of the twisted pair wire 4. However, the twist pitches P1 and P4 of the twisted pair wires 4 and 9 may be different from each other. The twist pitch P4 of the second twisted pair wire 9 is a distance along the longitudinal direction of the second twisted pair wire 9 in which any third electric wire 8 is located at the same position in the circumferential direction of the second twisted pair wire 9. is there.

The second twisted pair 9 is arranged on the side where the twisted pair 4 is not arranged, between the pair of first electric wires 2 in the circumferential direction. The second twisted pair 9 is arranged so as to enter the valley portion between the pair of first electric wires 2. In the cross section of FIG. 4A, one first electric wire 2, the second twisted pair wire 9, the other first electric wire 2, and the twisted pair wire 4 are sequentially arranged in the clockwise direction.

In the cable 1a including the two twisted pair wires 4 and 9, for example, when the first electric wires 2 are arranged adjacent to each other in the circumferential direction (when both pair twisted wires 4 and 9 are arranged adjacent to each other) , The center of gravity of the assembly 5 deviates largely from the center position of the assembly 5, and in this state, the twisted paired wires 4, 9 and the first electric wire 2 are twisted together to form the assembly 5, It will be twisted as a whole. Therefore, it is difficult to manufacture the linear cable 1, and there is a problem that flexibility is deteriorated due to occurrence of a direction that is difficult to bend in a part of the longitudinal direction. As in the present embodiment, the paired twisted wire 4 and the second paired twisted wire 9 are arranged between the pair of first electric wires 2 in the circumferential direction, so that the linear cable 1 can be easily manufactured. In addition, it is possible to suppress the problem that the direction that is difficult to bend occurs in a part of the longitudinal direction, and it is possible to suppress the decrease in flexibility.

Further, in the cable 1a, the twisted pair wire 4 and the second twisted pair wire 9 are separated from each other mainly by the pair of first electric wires 2 which supply the drive current to the EPB 101 after the vehicle is stopped. This makes it possible to reduce crosstalk between the twisted pair wire 4 and the second twisted pair wire 9, even if the shield conductors provided around the twisted pair wires 4 and 9 are omitted.

Even in the cable 1a further including the second twisted wire 9, the tape member 6 is broken when the tape member 6 is wound by making the tape member 6 have a tensile strength in the width direction smaller than a tensile strength in the longitudinal direction. It is possible to prevent the tape member 6 from being easily broken at the time of terminal processing, and to improve the workability of the stripping work for removing the sheath 7 and the tape member 6 while suppressing the occurrence of the occurrence.

Also in the cable 1a further including the second twisted wire 9, the surface roughness of the surface of the tape member 6 on the sheath 7 side is made rougher than the surface roughness of the surface on the assembly 5 side, so that the tape member 6 improves the adhesiveness between the sheath 7 and the sheath 7, and improves the workability of the stripping work, and makes the assembly 5 (electric wires 2, 3, 8) slippery with respect to the tape member 6 to bend the cable 1. Can be improved.

The cable 1b shown in FIGS. 5A and 5B is the cable 1 of FIG. 1 in which the twisting direction (broken line arrow B) of the assembly 5 is opposite.

That is, in the cable 1b, the twisting direction of the twisted pair wire 4, the twisting direction of the assembly 5, and the winding direction of the tape member 6 are the same.

By setting the twisting direction of the twisted pair wire 4, the twisting direction of the assembly 5, and the winding direction of the tape member 6 to be the same direction, the twisting of the assembly 5 will be natural when the tape member 6 is unwound during terminal processing. When the aggregate 5 is loosened and the twist of the assembly 5 is loosened, the twist of the twisted pair wire 4 is naturally loosened, and the electric wires 2 and 3 are easily loosened. As a result, the dismantling property of the cable 1 is improved, and the workability at the time of terminal processing is improved.

Further, by setting the twisting direction of the twisted pair wire 4, the twisting direction of the assembly 5, and the winding direction of the tape member 6 to be the same direction, when the cable 1b is twisted, the twisted pair wire 4 and the assembly 5 are twisted. Since the tape member 6 and the tape member 6 are opened and closed in synchronization with each other, the durability against twisting can be improved.

In this regard, for example, when the twisting direction of the assembly 5 and the winding direction of the tape member 6 are opposite to each other, when twist is applied to the cable 1b in the direction in which the assembly 5 opens (the diameter of the assembly 5 increases), Since the twisting direction of the assembly 5 and the winding direction of the tape member 6 are opposite to each other, the tape member 6 is closed in reverse (the diameter of the tape member 6 becomes smaller). At this time, the tape member 6 keeps the assembly 5 from trying to open, stress is applied to the assembly 5, and an excessive load is applied to a part of the twisted pair wire 4. In the present embodiment, the twisting direction of the twisted pair wire 4, the twisting direction of the assembly 5, and the winding direction of the tape member 6 are the same, and the twisted pair wire 4, the assembly 5, and the tape member 6 are synchronized. I try to open and close it. This makes it possible to improve the durability of the cable 1b against twisting.

Furthermore, by making the twisting direction of the twisted pair wire 4 and the twisting direction of the assembly 5 the same direction, when twisting the assembly 5, two second electric wires 3 are twisted to form a twisted pair wire 4. The twisted pair wire 4 and the first electric wire 2 are twisted together in the direction along the given bending tendency. Therefore, when the cable 1b is bent, the twisted pair wire 4 and the assembly 5 are synchronized and expand and contract in the longitudinal direction of the cable 1, so that the cable 1b is easily bent and the flexibility of the cable 1b is improved. It will be possible.

In the cable 1b, since the assembly 5 is formed by twisting the twisted pair wire 4 in the direction along the bending tendency of the twisted pair wire 4, the sheath 7 is not unwound by hand, and is separated from the sheath 7 by a dedicated strip device or the like. When the tape member 6 is removed at the same time, the twisted pair 4 and the first electric wire 2 tend to be maintained in a twisted state due to the bending tendency of the twisted pair 4. When the removal length of the sheath 7 is lengthened at the time of terminal processing, the stripping work is performed in a plurality of times. Since it is maintained in a twisted state, it becomes possible to easily perform a plurality of strip operations.

In the cable 1b, since the twisting direction of the twisted pair wire 4 is the same as the twisting direction of the aggregate 5, the twisting pitch P1 of the twisted pair wire 4 and the twisting pitch P2 of the aggregate 5 are the same. The positional relationship between the second electric wire 3 and the second electric wire 3 is always the same in the longitudinal direction, and the appearance of the cable 1b may be distorted. Therefore, the twist pitch P1 of the twisted pair wire 4 and the twist pitch P2 of the aggregate 5 are made different (specifically, the twist pitch P1 of the twisted pair wire 4 is set to be greater than the twist pitch P2 of the aggregate 5). It is desirable to reduce the twist pitch P2 of the body 5 by 10% or more and 80% or less. If the twist pitch P1 of the twisted pair wire 4 is made larger than the twist pitch P2 of the aggregate 5, the twist pitch P1 of the twisted pair wire 4 may fluctuate when the aggregate 5 is twisted together. It is desirable that the twist pitch P1 of 4 is at least smaller than the twist pitch P2 of the aggregate 5.

When the twist pitch P2 of the assembly 5 is reduced, the cable 1b is easily bent and the flexibility is improved, but the twist has no margin and the durability against twisting is reduced. On the contrary, if the twist pitch P2 of the assembly 5 is increased, the durability against twisting is improved but the flexibility is decreased. In the cable 1b, when twist is applied, the twisted pair P, the assembly 5, and the tape member 6 can be opened and closed in synchronization with each other to distribute the load. Therefore, the twist pitch P2 of the assembly 5 can be reduced. Even when the flexibility is improved by the above method, it is possible to sufficiently secure the durability against twisting.

When the twist pitch P2 of the assembly 5 and the winding pitch P3 of the tape member 6 are the same, the tape member 6 causes the twisted wire 4 and the first electric wire due to the pressure when the outer circumference of the tape member 6 is covered with the sheath 7. 2 or between the pair of first electric wires 2 easily, the cross-sectional shape of the assembly 5 around which the tape member 6 is wound becomes distorted, and the appearance is deteriorated, or the assembly 5 has the tape member 6. There is a risk that it will become less slippery inside and the flexibility will decrease. Therefore, the twist pitch P2 of the assembly 5 and the winding pitch P3 of the tape member 6 are made different (specifically, the winding pitch P3 of the tape member 6 is set to be smaller than the twist pitch P2 of the assembly 5). It is desirable to reduce the twist pitch P2 by 10% or more and 80% or less.

Further, the winding pitch P3 of the tape member 6 may be set to be the twist pitch P1 of the twisted pair wire 4 or more. By doing so, the distortion of the tape member 6 in the portion in contact with the twisted pair 4 can be reduced, and the cross-sectional shape of the cable 1b can be easily formed into a circular shape.

The cable 1c shown in FIGS. 6(a) and 6(b) is the same as the cable 1b in FIG. 5, but further includes a second twisted pair 9 in which a pair of third electric wires 8 are twisted together. In other words, the cable 1c is the cable 1a of FIG. 4 in which the twist direction (broken line arrow B) of the assembly 5 is opposite.

Also in the cable 1c provided with the second twisted pair wire 9, the twisted direction of the twisted paired wires 4 and 9, the twisted direction of the assembly 5, and the winding direction of the tape member 6 are the same, so that the electric wire 2 , 3 and 8 can be easily loosened to improve dismantling property, workability of terminal processing can be further improved, and durability against twisting can be improved.
