Japanese Patent No. 3909963

By the way, in a vehicle such as a hybrid vehicle, a plurality of types of electric wires such as a power wire through which a high voltage and a large current flow and a weak electric wire are routed. Here, for example, when inserting a power wire and a weak electric wire through the same pipe, shield the braided wire etc. on the weak electric wire to prevent the influence of electromagnetic noise generated by the power wire. There is a problem that it is necessary to pass through the pipe, the number of parts is increased, and processing is troublesome.

As a result of examining this problem, it was found that the above problem can be solved by dividing the inside of the pipe into two or more by a flat partition wall. However, when bending is performed in order to make the pipe having such a configuration into a shape according to the wiring location, there is a problem that the partition wall acts as a beam and is difficult to be deformed into the intended shape. .

The technology described in the present specification has been completed based on the above-described circumstances, and a shield conductive path capable of inserting a plurality of types of electric wires and easily processed into a desired shape is provided. The purpose is to provide.

The technology described in the present specification is a shield conductive path including a plurality of electric wires formed by surrounding a conductor with an insulating coating, and a metal pipe that shields and protects by inserting the electric wires. The pipe has a cylindrical tube body through which the electric wire is inserted, and a partition wall extending from an inner wall of the tube body and partitioning the inside of the tube body into a first region and a second region, Of the partition wall, the portions near both ends located in the vicinity of the inner wall of the cylinder body are a pair of end convex portions bent in a convex shape in the direction from the first region toward the second region. In addition, a concave portion bent in a concave shape in the direction from the first region toward the second region is formed between the pair of end convex portions in the partition wall, and the inner wall of the cylinder body Projecting inward of the cylinder body Rutotomoni ribs extending in the axial direction of said barrel body is formed.

According to the technique described in this specification, the inside of the cylinder main body is divided into the first region and the second region by the partition wall. For this reason, an electric wire can be easily shielded, without taking a shield measure separately with respect to an electric wire by inserting an electric wire in each of the 1st field and the 2nd field.

Since the partition wall includes a pair of end convex portions and a concave portion, at least one of the end convex portion or the concave portion is bent even when the pipe is bent from any direction. As a result, the pipe can be bent easily.

Moreover, the uneven | corrugated shape is formed in the inside of a 1st area | region and the inside of a 2nd area | region by the rib formed in the inner wall of a cylinder main body, the edge part convex part of a partition wall, and a concave part. . This uneven shape prevents the electric wire from rolling freely inside the cylinder body. Thereby, since it is suppressed that an electric wire collides inside a cylinder main body, or an electric wire collides with the inner wall of a cylinder main body, an electric wire can be protected reliably.

According to the technique described in this specification, it is possible to provide a shield conductive path through which a plurality of types of electric wires can be inserted and can be easily processed into a desired shape.

<Outline of Embodiment>
The technology described in the present specification is a shield conductive path including a plurality of electric wires formed by surrounding a conductor with an insulating coating, and a metal pipe that shields and protects by inserting the electric wires. The pipe has a cylindrical tube body through which the electric wire is inserted, and a partition wall extending from an inner wall of the tube body and partitioning the inside of the tube body into a first region and a second region, Of the partition wall, the portions near both ends located in the vicinity of the inner wall of the cylinder body are a pair of end convex portions bent in a convex shape in the direction from the first region toward the second region. In addition, a concave portion bent in a concave shape in the direction from the first region toward the second region is formed between the pair of end convex portions in the partition wall, and the inner wall of the cylinder body Projecting inward of the cylinder body Ribs extending in the axial direction of said barrel body is formed with.

In the shield conductive path, the radius of curvature of the end convex portion is set to be equal to or larger than the radius of the electric wire inserted into the first region.

According to said aspect, it is suppressed that an electric wire fits into the part by the side of the 1st area | region of an edge part convex part. Thereby, when a pipe is bent, it is suppressed that an electric wire fits into the part by the side of the 1st field of a convex part, and is compressed. As a result, the electric wire can be protected when the pipe is bent.

In the shield conductive path, the rib is provided on an inner wall of the cylinder body located in the second region, and the rib is formed at a position facing the end convex portion of the partition wall. Yes.

According to the above aspect, in the second region, the space between the rib and the end convex portion is narrower than other portions. Thereby, it can suppress that an electric wire passes between a rib and an edge convex part, and rolls.

In the shield conductive path, the interval between the rib and the end convex portion is set to be smaller than the diameter of the electric wire inserted into the second region.

According to the above aspect, it is possible to reliably suppress the electric wire from passing through between the rib and the end convex portion and rolling.

In the shield conductive path, the partition wall is formed with an intermediate convex portion that is different from the convex portion at the end and is bent in a convex shape in the direction from the first region to the second region. The rib is formed at a position facing the intermediate convex portion.

According to the above aspect, in the second region, the space between the rib and the intermediate convex portion is narrower than other portions. Thereby, it can suppress that an electric wire passes between a rib and an intermediate | middle convex-shaped part, and rolls.

In the shield conductive path, the first electric wire inserted into the first region among the plurality of electric wires and the second electric wire inserted into the second region among the plurality of electric wires are different in type.

According to the above aspect, by inserting different types of electric wires into the first region and the second region respectively, it is possible to shield a plurality of types of electric wires without taking a shield measure.

In the shield conductive path, the inner wall of the cylinder body on the first area side and the wall surface on the first area side of the partition wall are smoothly connected, and the cylinder body on the second area side. The inner wall and the wall surface on the second region side of the partition wall are smoothly connected.

When the pipe is bent, stress tends to concentrate on the boundary between the inner wall of the cylinder body and the partition wall. According to this aspect, the boundary part of the inner wall of a cylinder main body and a partition wall is connected smoothly. Thereby, it can suppress that stress concentrates on the boundary part of the inner wall of a cylinder main body, and a partition wall. As a result, when bending the pipe, it is not necessary to strictly consider the strength of the boundary portion between the inner wall of the cylinder body and the partition wall, so that the pipe can be bent easily. In addition, that the boundary part is smoothly connected means that the curvature of the inner wall of a cylinder main body and the curvature of the wall surface of a partition wall are changing continuously.

The first embodiment will be described with reference to FIGS. 1 to 5. In the following description, for some of the same members, only some members may be denoted by reference numerals, and other members may be omitted from reference numerals.

As shown in FIG. 1, the shield conductive path 110 according to the present embodiment is disposed in a vehicle 111 such as an electric vehicle or a hybrid vehicle. An engine room is provided in the front portion of the vehicle body 112 of the vehicle 111. In the engine room, a motor 113, an inverter 114 constituting a power circuit for driving the motor 113, and a gasoline-driven engine 115 are accommodated. A battery 116 constituting a power circuit is mounted on the rear portion of the vehicle body 112. Between the inverter 114 and the battery 116, a shield conductive path 110 and an in-vehicle conductive path 117A are routed. In addition, an in-vehicle conductive path 117B is routed between the inverter 114 and the motor 113.

The shield conductive path 110 according to the present embodiment has a configuration in which two types of non-shield type

electric wires

118 and 119 are inserted into a pipe 120 having both a collective shield function and an electric wire protection function.

In the present embodiment, two first electric wires 118 are arranged in the upper first region 121 (details will be described later) in FIG. 2, and one in the lower second region 122 in FIG. 2. The second electric wire 119 is arranged, and these are collectively referred to as two types of

electric wires

118 and 119.

The two types of

electric wires

118 and 119 have different cross-sectional diameters, and the first electric wire 118 has a smaller cross-sectional diameter than the second electric wire 119. Each of the two types of

electric wires

118 and 119 has a form in which the outer periphery of a

conductor

123A, 123B made of metal (for example, aluminum alloy, aluminum, copper, copper alloy, etc.) is surrounded by insulating

coatings

124A, 124B made of synthetic resin. .

The

conductors

123A and 123B of the two types of

electric wires

118 and 119 are each formed of a stranded wire in which a plurality of fine wires are close to each other in a spiral shape, and are formed in a substantially circular cross section. The cross-sectional shape of the outer periphery of the insulating

coatings

124A and 124B is also formed into a substantially circular cross-section, similar to the

conductors

123A and 123B. Note that the

conductors

123A and 123B of the two types of

electric wires

118 and 119 may be composed of rod-shaped single core wires.

In the present embodiment, the first electric wire 118 and the second electric wire 119 are of different types. For example, one of the first electric wire 118 and the second electric wire 119 may be a high-voltage electric wire and the other may be a low-voltage electric wire. In the present embodiment, the first electric wire 118 is a high voltage system, and the second electric wire 119 is a low voltage system.

The pipe 120 is made of metal (for example, aluminum alloy, copper alloy, stainless steel, etc.), and has a cylindrical main body 125 having a substantially circular cross-sectional cylindrical shape, and an inner wall 127 of the cylindrical main body 125 extending from the inner wall 126 of the cylindrical main body 125. And a partition wall 128 for partitioning. The cylinder main body 125 and the partition wall 128 are integrally formed by extrusion molding. The metal which comprises the pipe 120 can select arbitrary metals as needed. Further, a plated layer or a paint layer may be formed on the outer surface or the inner surface of the pipe 120 as necessary.

Now, the partition wall 128 is formed over the entire length of the pipe 120, and is formed from one end of the inner wall 126 of the cylinder body 125 to the inner wall 126 facing the one end. The cross-sectional shape of the partition wall 128 in the direction perpendicular to the axial direction of the cylinder main body 125 (the direction penetrating the paper surface of FIG. 2) is a gently curved shape as shown in FIG.

The interior 127 of the cylinder main body 125 is partitioned into a first region 121 and a second region 122 by a partition wall 128. The first region 121 and the second region 122 are spaces surrounded by the inner wall 126 of the cylinder body 125 and the partition wall 128. A first electric wire 118 is inserted into the first region 121 from an opening on one end side of the pipe 120. Similarly, the second electric wire 119 is inserted into the second region 122 from the opening on one end side of the pipe 120. In the present embodiment, in FIG. 2, the upper space in the drawing through which the first electric wire 118 is inserted is referred to as a first region 121, and the lower space in the drawing through which the second electric wire 119 is inserted is referred to as a second region 122.

A gap 129 A is formed between the insulating coating 124 A of the first electric wire 118 inserted into the first region 121, the partition wall 128, and the inner wall 126 of the cylinder main body 125. A gap 129 B is also formed between the insulating coating 124 B of the second electric wire 119 inserted into the second region 122, the partition wall 128, and the inner wall 126 of the tube main body 125.

As shown in FIG. 2, a part of the partition wall 128 near the left and right ends in FIG. 2 has a pair of shapes bent convexly downward (in the direction from the first region 121 to the second region 122). It is made into the edge part convex-shaped part 130 of this. The end convex portion 130 is formed in a region in the vicinity of a portion of the partition wall 128 where the partition wall 128 extends from the inner wall 126 of the cylinder body 125.

As shown in FIG. 3, the radius of curvature RA of the end convex portion 130 is set to be equal to the radius RB of the first electric wire 118 or larger than the radius RB of the first electric wire 118. In the present embodiment, the radius of curvature RA of the end convex portion 130 is set larger than the radius RB of the first electric wire 118. In the present embodiment, the radius RB of the first electric wire 118 refers to the outer diameter of the insulation coating 124A covered with the conductor 123A.

In this embodiment, the radius of curvature RA of the pair of end convex portions 130 is set to the same value. In addition, the curvature radius RA of a pair of edge part convex part 130 may be set to a different value.

The inner wall 126 of the cylinder body 125 on the first region 121 side and the wall surface on the first region 121 side of the partition wall 128 are connected by a smooth curved surface 131. Thereby, the inner wall 126 of the cylinder main body 125 and the wall surface by the side of the 1st area | region 121 among the edge part convex parts 130 are connected smoothly. In other words, no clear boundary line or step is formed between the inner wall 126 of the cylinder main body 125 and the wall surface on the first region 121 side of the end convex portion 130.

As shown in FIG. 2, the partition wall 128 has a shape bent in a concave shape from above to below (a direction from the first region 121 to the second region 122) between the pair of end convex portions 130. A concave portion 132 is formed. In the present embodiment, the concave portion 132 is formed in the vicinity of an intermediate position between the pair of end convex portions 130 in the partition wall 128.

On the wall surface of the partition wall 128 on the first region 121 side, the pair of end convex portions 130 and the concave portion 132 are connected by a smooth curved surface 134. In other words, a clear boundary line or step is not formed between the pair of end convex portions 130 and the concave portion 132 on the wall surface of the partition wall 128 on the first region 121 side.

Two ribs 133 projecting inward of the cylinder body 125 are formed on the inner wall 126 of the cylinder body 125 located on the second region 122 side. The rib 133 is formed so as to extend in the axial direction of the cylinder main body 125 (direction passing through the paper surface in FIG. 2), and is formed over the entire length of the cylinder main body 125. The cylinder body 125 and the rib 133 are integrally formed by extrusion molding.

The region located between the vertices of the two ribs 133 in the inner wall 126 of the cylinder body 125 is connected by a smooth curved surface 135. Further, with respect to the two ribs 133, the two ribs 133 and the inner wall 126 of the cylinder main body 125 are connected by a smooth curved surface 136 in the outer region in the left-right direction in FIG. 2. Thus, a clear boundary line or step is not formed between the two ribs 133 and the inner wall 126 of the cylinder body 125.

Each of the two ribs 133 is formed at a position facing the end convex portion 130 formed on the partition wall 128. The distance between the apex of the rib 133 and the end convex portion 130 is set to be smaller than the diameter (outer diameter dimension) of the second electric wire 119 (see FIG. 3). Thus, the second electric wire 119 cannot pass through the space between the rib 133 and the end convex portion 130.

The inner wall 126 of the cylinder main body 125 on the second region 122 side and the wall surface on the second region 122 side of the partition wall 128 are connected by a smooth curved surface 137. In other words, no clear boundary line or step is formed between the inner wall 126 of the cylinder main body 125 on the second region 122 side and the wall surface on the second region 122 side of the partition wall 128.

(Manufacturing process of embodiment)
Then, an example of the manufacturing process of this embodiment is shown. In addition, the manufacturing process of this embodiment is not limited to the following description.

When producing the shield conductive path 110 of the present embodiment, two types of

electric wires

118 and 119 are inserted into the inside 127 of the tube main body 125 of the pipe 120. Two first electric wires 118 are inserted into the first region 121 from the opening on one end side of the pipe 120, and one second electric wire 119 is inserted into the second region 122.

Subsequently, the pipe 120 is bent. In addition, the bending process with respect to the pipe 120 may be performed before the two types of

electric wires

118 and 119 are inserted.

When the pipe 120 is bent, the posture of the pipe 120 is not limited. For example, FIG. 4 shows an example in which the pipe 120 is bent in such a manner that the diameter of the pipe 120 is reduced in the direction orthogonal to the partition wall 128 (the vertical direction in FIG. 4). In this case, the diameter of the pipe 120 is reduced in the direction orthogonal to the partition wall 128 (the vertical direction in FIG. 4). On the other hand, the diameter of the pipe 120 is increased in the left-right direction in FIG. In this case, the partition wall 128 is deformed so that the end convex portion 130 follows the pipe 120 and has a smaller curvature. On the other hand, the concave portion 132 is deformed so that the curvature is increased because the compressive force from the pair of end convex portions 130 acts.

Further, for example, as shown in FIG. 5, an example is shown in which the pipe 120 is bent in such a manner that the diameter of the pipe 120 is increased in a direction orthogonal to the partition wall 128 (vertical direction in FIG. 5). In this case, the diameter of the pipe 120 is increased in the direction orthogonal to the partition wall 128 (the vertical direction in FIG. 5). On the other hand, the pipe 120 is reduced in diameter in the left-right direction in FIG. In this case, since the compressive force acts on the partition wall 128, the end convex portion 130 and the concave portion 132 are deformed so that the curvature becomes large.

When bending the pipe 120, even when the pipe 120 is bent in a posture different from that shown in FIGS. 4 and 5, the end convex portion 130 and the concave portion 132 formed on the partition wall 128 are: Various deformations are made according to the force applied to each.

(Operation and effect of the embodiment)
Then, the effect | action and effect of this embodiment are demonstrated. In the pipe 120 according to the present embodiment, the interior 127 of the cylinder main body 125 is partitioned into a first region 121 and a second region 122 by a partition wall 128. For this reason, the

electric wires

118 and 119 are inserted into the first region 121 and the second region 122, respectively, so that the

electric wires

118 and 119 can be easily shielded without individually taking measures for shielding the

electric wires

118 and 119. can do.

In addition, since the partition wall 128 has a pair of end convex portions 130 and a concave portion 132, at least one of the end convex portions 130 or the concave portions 132, even when the pipe 120 is bent from any direction. However, it is designed to bend according to the applied force. As a result, the pipe 120 can be bent easily.

Further, the inside 127 of the first region 121 and the inside 127 of the second region 122 are formed by the rib 133 formed on the inner wall 126 of the cylinder body 125, the end convex portion 130, and the concave portion 132 of the partition wall 128. A concave-convex shape is formed. Due to this uneven shape, the

electric wires

118 and 119 are prevented from rolling freely inside the cylinder body 125. This prevents the

electric wires

118 and 119 from colliding with each other in the inside 127 of the tube main body 125 and the

electric wires

118 and 119 and the inner wall 126 of the tube main body 125 from colliding with each other. Can be protected.

Further, according to the present embodiment, the radius of curvature RA of the end convex portion 130 is the same as the radius RB of the first electric wire 118 inserted into the first region 121 or the radius RB of the first electric wire 118. Is set larger than. Thereby, as shown in FIG.2 and FIG.3, it is suppressed that the 1st electric wire 118 fits into the part by the side of the 1st area | region 121 of the edge part convex part 130. FIG. As a result, when the pipe 120 is bent, the first electric wire 118 is suppressed from being fitted into the first region 121 side portion of the end convex portion 130 and being compressed, so that the pipe 120 is bent. In this case, the first electric wire 118 can be protected. For example, when the pipe 120 is bent in the manner shown in FIG. 4, the first electric wire 118 has a gap 129 A between the inner wall 126 of the cylinder body 125 and the partition wall 128 in the first region 121. Has been arranged. Further, even when the pipe 120 is bent in the manner shown in FIG. 5, the first electric wire 118 has a gap between the inner wall 126 of the cylinder body 125 and the partition wall 128 in the first region 121. It is arranged with 129A.

Further, in the present embodiment, the rib 133 is provided on the inner wall 126 of the cylinder main body 125 located in the second region 122, and the rib 133 is located at a position facing the end convex portion 130 of the partition wall 128. Is formed. Thereby, in 2nd area | region 122, between rib 133 and the edge part convex-shaped part 130 is narrow compared with another part. Thereby, it can suppress that the 2nd electric wire 119 passes between the rib 133 and the edge part convex-shaped part 130, and rolls.

Furthermore, the interval between the rib 133 and the end convex portion 130 is set to be smaller than the diameter of the second electric wire 119 inserted through the second region 122. Thereby, it can suppress reliably that the 2nd electric wire 119 passes between the rib 133 and the edge convex part 130, and rolls (refer FIG. 3).

In addition, according to the present embodiment, the first electric wire 118 inserted into the first region 121 among the plurality of

electric wires

118 and 119 and the second electric wire inserted into the second region 122 among the plurality of

electric wires

118 and 119. 119 is different in type. Thereby, different types of

electric wires

118 and 119 are inserted through the first region 121 and the second region 122, respectively, so that a plurality of types of

electric wires

118 and 119 can be shielded without taking individual shielding measures. Can do.

Further, according to the present embodiment, the inner wall 126 of the cylinder main body 125 on the first region 121 side and the wall surface on the first region 121 side of the partition wall 128 are connected by the smooth curved surface 131, and the second The inner wall 126 of the cylinder main body 125 on the region 122 side and the wall surface on the second region 122 side of the partition wall 128 are connected by a smooth curved surface 137.

When the pipe 120 is bent, stress is easily concentrated on the boundary portion between the inner wall 126 of the cylinder main body 125 and the partition wall 128. According to the present embodiment, the boundary portion between the inner wall 126 of the cylinder main body 125 and the partition wall 128 is connected by the

curved surfaces

131 and 137. Thereby, it can suppress that stress concentrates on the boundary part of the inner wall 126 of the cylinder main body 125, and the partition wall 128. FIG. As a result, when bending the pipe 120, it is not necessary to strictly consider the strength of the boundary portion between the inner wall 126 of the cylinder main body 125 and the partition wall 128, so that the pipe 120 can be easily bent. Can do.

In this embodiment, a gap 129 A is formed between the insulation coating of the first electric wire 118 and the inner wall 126 of the cylinder main body 125 and the wall surface on the first region 121 side of the partition wall 128. Further, a gap 129 B is also formed between the second electric wire 119 and the wall surface on the second region 122 side of the inner wall 126 and the partition wall 128 of the cylinder main body 125. Thereby, it can be easily bent without damaging each

insulation coating

124A, 124B of the

electric wires

118, 119.

<Embodiment 2>
Next, the shield conductive path 150 according to the second embodiment will be described with reference to FIG. In this embodiment, two concave portions 154 are formed between the pair of end convex portions 153 in the partition wall 152 formed in the pipe 151. The curvature radii of the two concave portions 154 are set to the same value. Note that the curvature radii of the two concave portions 154 may be set to different values.

Further, the partition wall 152 is different from the end convex portion 153 between the two concave portions 154, and is downward in FIG. 6 (direction from the first region 155 to the second region 156). An intermediate convex portion 157 bent in a convex shape is formed. The intermediate convex portion 157 is formed by extrusion molding.

Three

ribs

160A, 160B, 160C projecting inward of the cylinder main body 158 are formed on the inner wall 159 of the cylinder main body 158 located on the second region 156 side. The ribs 160 A, 160 B, and 160 C are formed to extend in the axial direction of the cylinder main body 158 (direction passing through the paper surface in FIG. 6), and are formed over the entire length of the cylinder main body 158. The cylinder body 158 and the

ribs

160A, 160B, 160C are integrally formed by extrusion molding.

6, the two ribs 160 A and 160 C located at both left and right ends are respectively arranged to face the two end convex portions 153 formed on the partition wall 152.
