Description

  The present invention relates to an electric wire protector that covers the periphery of a plurality of electric wires and a wire harness including the same.

  2. Description of the Related Art Conventionally, a wire harness mounted on a vehicle such as an automobile often includes a cylindrical wire protector such as a corrugated tube that covers the periphery of a plurality of electric wires. When the electric wire is covered with the electric wire protector, it does not come into contact with surrounding members according to vibration or movement of the movable part, and durability is increased.

  Patent Document 1 discloses a flat cylindrical corrugated tube that covers the periphery of a plurality of electric wires arranged in parallel. Since the flat cylindrical wire protector as shown in Patent Document 1 holds a plurality of wires in a state of being arranged in parallel, there is a height restriction such as a space under the floor of a car body of an automobile. It is particularly suitable for wiring a wire harness to a strict wiring space.

  Further, in the wire harness, when the plurality of electric wires are held in a state of being arranged in parallel, the outline of the entire wire bundle is formed as compared with the case where the plurality of electric wires are held in a state of being stacked in the vertical direction and the horizontal direction. The surface area of the portion increases, and the heat dissipation of the entire wire bundle increases.

  In particular, when the electric wire is a flat cable, when a plurality of flat cables are held in a state where they are arranged in parallel in a direction along the flat surface of each flat cable, a plurality of flat cables are held in a stacked state As compared with the above, the effect of improving the heat dissipation due to the increase of the surface area becomes more remarkable. That is, when a flat cylindrical wire protector is employed and a plurality of wires are held in parallel, the heat dissipation of the entire wire bundle is greater than when a cylindrical wire protector is employed. Will increase.

  In an electric vehicle such as a hybrid vehicle and an electric vehicle, the wire harness may be used for the purpose of supplying large electric power to a high-output motor. In this case, the heat generation amount of the electric wire is large. Therefore, in the wire harness of an electric vehicle, it is important that the heat dissipation of the entire wire bundle is high.

JP 2010-47033 A

  By the way, electric wire protectors, such as a corrugated tube, are generally comprised of a resin molded member. When the resin wire protector is formed in a flat cylindrical shape, a portion forming the flat surface is easily bent in the width direction. In particular, when the flat cylindrical wire protector holds a plurality of flat cables in a state of being arranged in parallel, the portion forming the flat surface becomes wider and more easily bent.

  Then, in the flat cylindrical wire protector, when the portion forming the flat surface is bent so as to bulge outward in the width direction, the wire moves to the gap formed by the bending, and a plurality of wires are stacked. End up. In particular, since flat cables can move into narrow gaps, they tend to overlap. When a plurality of electric wires are stacked, the heat dissipation of the entire wire bundle is lowered.

  As described above, the conventional flat cylindrical wire protector has a problem that a plurality of wires are stacked due to the bending thereof, and heat dissipation of the entire wire bundle is lowered. In particular, when the electric wire is a flat cable, the problem of deterioration in heat dissipation due to stacking becomes more prominent.

  In the present invention, when the wire harness includes a flat cylindrical wire protector that covers the periphery of a plurality of electric wires arranged in parallel, the plurality of wires are stacked due to the bending of the wire protector, and the entire wire bundle is dissipated. The purpose is to solve the problem of lowering the performance.

  The wire harness according to the present invention includes a plurality of electric wires and an electric wire protector. The wire protector includes a first cover member and a second cover member combined from both sides of a plurality of electric wires arranged in parallel, and the first cover member and the second cover member are flat cylindrical shapes that cover the periphery of the electric wire. Is formed. Furthermore, the through-hole is formed in the position which opposes between each of the some electric wire in a 1st cover member. Furthermore, the protrusion part is formed in the position which opposes between each of the some electric wire in a 2nd cover member. Furthermore, the protrusion has a portion on the base side from the tip portion that partitions the plurality of electric wires individually and is passed through the through hole of the first cover member, and the tip portion has a width larger than the diameter of the through hole by melting processing. Formed to hold the first cover member.

  Moreover, it is possible that the wire harness which concerns on this invention is further equipped with the braided wire which covers a some electric wire collectively between an electric wire protector and an electric wire. In this case, the protruding portion is passed through the gap of the braided wire and through the through hole of the first cover member to partition the plurality of electric wires individually.

  In the wire harness according to the present invention, each of the plurality of electric wires may be a flat cable.

  Further, in the wire harness according to the present invention, a ridge that fills the gap between the protrusion of the second cover member and the electric wire is formed at the edge of the through hole in the first cover member, and the protrusion of the second cover member It is conceivable that the root portion is formed thicker than the portion that passes through the through hole of the first cover member.

  Moreover, this invention can also be caught as invention of the wire protector employ | adopted as the wire harness which concerns on this invention. That is, the wire protector according to the present invention includes a first cover member and a second cover member that are formed into a flat cylindrical shape covering the periphery of the wire by being combined from both sides of the plurality of wires arranged in parallel. Furthermore, in the wire protector according to the present invention, through holes are formed at positions facing each other between the plurality of wires in the first cover member. Furthermore, the protrusion part penetrated by the through-hole of a 1st cover member is formed in the position which opposes between each of several electric wires in a 2nd cover member.

  In the wire protector according to the present invention, the first cover member and the second cover member are combined from both sides of the plurality of electric wires arranged in parallel, and then passed through the through hole of the first cover member. The tip portion of the protrusion of the two cover member is melt processed.

  In the wire harness which concerns on this invention, the projection part formed in the 2nd cover member which comprises an electric wire protector partitions a some electric wire in an electric wire protector separately. Further, the protrusion is a state in which the first cover member and the second cover member are combined in a flat cylindrical shape by the melted tip portion functioning as a retaining portion from the through hole of the first cover member. Hold on.

  Therefore, in the flat cylindrical wire protector, the protrusions prevent the portions forming the flat surface from bending in the width direction and prevent the wires from moving in the lateral direction and overlapping each other. . Therefore, in the wire harness according to the present invention, there is no problem that a plurality of wires are stacked due to the bending of the wire protector and the heat dissipation of the entire wire bundle is reduced.

  Further, in the wire harness according to the present invention, the protruding portion also serves as a lock function for holding the first cover member on the second cover member in addition to the function of preventing the plurality of electric wires from overlapping each other. In addition, it is easy to automate the process of melting the tip portion of the protrusion protruding from the inside to the outside of the first cover member. Therefore, in the wire harness according to the present invention, it is possible to omit or simplify complicated processes such as taping work for holding the first cover member and the second cover member in a combined state in a cylindrical shape. Become.

  In addition, when the wire harness includes a braided wire that collectively covers a plurality of electric wires between the electric wire protector and the electric wires, since the frictional resistance between the electric wires and the braided wire is small, the electric wires are within the braided wire. Easy to skid. Therefore, the wire harness according to the present invention has a more remarkable effect of preventing the movement of the electric wire when there is a braided wire that covers a plurality of electric wires at once. Furthermore, since the protruding portion is passed through the gap of the braided wire stitch, the braided wire is prevented from being displaced in the wire protector.

  Further, as described above, when the electric wire is a flat cable, the problem of deterioration in heat dissipation due to stacking becomes more prominent. Therefore, if this invention is applied to a wire harness provided with the several flat cable hold | maintained in parallel, it will be more effective.

  By the way, in the wire harness which concerns on this invention, when the clearance gap between an electric wire protector and an electric wire is large, the air layer of a clearance gap becomes a heat insulation layer which inhibits the heat dissipation of the whole wire bundle. Moreover, when the clearance gap between a braided wire and an electric wire is large, a shield effect will fall.

  Therefore, the raised portion formed at the edge of the through hole in the first cover member and the root portion of the thickly formed protrusion fill the gap between the protrusion and the electric wire, thereby conducting heat conduction in the wire protector. A poor air layer is reduced, and the heat dissipation of the entire wire bundle is further increased. Further, when the braided wire exists, the braided wire is pressed against the electric wire by the root portion of the raised portion and the protruding portion, and the shielding effect is enhanced.

It is a disassembled perspective view of the principal part of the wire harness 1 which concerns on embodiment of this invention. 2 is an exploded cross-sectional view of the main part of the wire harness 1. FIG. 2 is a cross-sectional view of a main part of the wire harness 1. FIG. 2 is a longitudinal sectional view of a main part of the wire harness 1. FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

  Hereinafter, the wire harness 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 4. The wire harness 1 connects, for example, a power supply source such as a battery or an inverter circuit of an electric vehicle and an electrical device such as a motor. As shown in FIGS. 1 to 4, the wire harness 1 includes a plurality of flat cables 9, a braided wire 8, and a corrugated tube 10.

<Flat cable>
The flat cable 9 is a flat electric wire in which a plurality of conductive wires 91 arranged in parallel are covered with an insulating coating. The flat cable 9 has a large surface area and excellent heat dissipation compared to a round cable having the same total cross-sectional area of the conducting wire 91. Further, the flat cable 9 is suitable for laying in a wiring space whose height is severely limited as compared with a round cable.

  The plurality of flat cables 9 are arranged in parallel in the direction along the flat surface of each flat cable 9, and the periphery thereof is covered with a corrugated tube 10.

<Braided line>
The braided wire 8 is a tubular shield member that collectively covers a plurality of flat cables 9 arranged in parallel. The braided wire 8 is a conductor having a structure in which a stranded wire in which fine metal wires such as a copper wire are brought together is knitted, and has elasticity due to the knitted structure.

  The plurality of flat cables 9 are covered with a corrugated tube 10 from the outside of the braided wire 8 that covers the periphery thereof. That is, the braided wire 8 collectively covers the plurality of flat cables 9 between the corrugated tube 10 and the flat cable 9.

<Corrugated tube>
The corrugated tube 10 is a flat cylindrical wire protector that covers a part of the plurality of flat cables 9 that are arranged in parallel and covered with the braided wire 8. The corrugated tube 10 has a bellows structure in which protruding portions 13 and dent portions 14 are alternately and continuously formed on the surface along the longitudinal direction thereof. Due to this bellows structure, the corrugated tube 10 has flexibility that is easy to bend in the longitudinal direction.

  In the assembly process of the wire harness 1, it is difficult to pass the flat cable 9 together with the braided wire 8 through the cylindrical corrugated tube 10. Therefore, the corrugated tube 10 includes a first cover member 11 and a second cover member 12 that are combined from both sides of a plurality of flat cables 9 covered with the braided wire 8. The first cover member 11 and the second cover member 12 are each formed with a shallow groove into which a plurality of flat cables 9 covered with the braided wire 8 are fitted. And the 1st cover member 11 and the 2nd cover member 12 are combined in the state of the braided wire 8 by combining in the state which the some flat cable 9 covered with the braided wire 8 fits in those groove parts. It becomes a flat cylindrical shape along which the plurality of flat cables 9 are covered and held while being arranged in parallel.

  Each of the first cover member 11 and the second cover member 12 constituting the corrugated tube 10 is made of non-conductive resin such as polyamide (PA), polypropylene (PP), polybutylene terephthalate (PBT), or ABS resin. It is an integrally molded member.

  In addition, in this embodiment, although the flat cable 9 arrange | positioned in the corrugated tube 10 shown by each figure is three, the case where the number of the flat cables 9 is two or four or more is also considered.

  Further, a through hole 17 penetrating from the inside to the outside is formed at a position facing between each of the plurality of flat cables 9 in a portion forming the flat surface of the first cover member 11. Accordingly, the through hole 17 is smaller in number in the width direction of the first cover member 11 than the number of the flat cables 9 at each predetermined position in the longitudinal direction of the first cover member 11, that is, flat. The cables 9 are formed side by side in the arrangement direction. When the number of the flat cables 9 is three, two through holes 17 are formed side by side in the width direction of the first cover member 11 at each predetermined position in the longitudinal direction of the first cover member 11. ing. Further, in the present embodiment, the through hole 17 is formed in a portion of the first cover member 11 that becomes the recessed portion 14 of the corrugated tube 10.

  In addition, although the dent part 14 is a part which forms a dent in the outer contour of the corrugated tube 10, in the inner contour of the corrugated tube 10, it is a part which forms a bulge adjacent to the braided wire 8 and the flat cable 9. is there.

  On the other hand, on the inner surface of the portion forming the flat surface of the second cover member 12, there are rod-like protrusions 18 protruding between the flat cables 9 at positions facing each other between the plurality of flat cables 9. Is formed. Each rod-shaped protrusion 18 is formed at a position facing each through hole 17 of the first cover member 11 in a state where the first cover member 11 and the second cover member 12 are combined.

  That is, the through hole 17 of the first cover member 11 and the rod-shaped protrusion 18 of the second cover member 12 are formed at the same position when viewed from the direction orthogonal to the flat surface of the corrugated tube 10. Further, in the present embodiment, the rod-shaped protrusion 18 is formed on the inner surface of the portion that becomes the dent portion 14 of the corrugated tube 10, that is, the portion that forms a bulge on the inner contour of the corrugated tube 10.

  2 and 3 are cross-sectional views of the wire harness 1 at a portion where the rod-shaped protrusion 18 of the corrugated tube 10 is formed. FIG. 3 shows the first cover member 11 and the first cover member 11 in the corrugated tube 10. It is an exploded cross-sectional view before the two cover members 12 are combined. FIG. 4 is a view showing a longitudinal cross section of the wire harness 1 at a portion where the rod-like protrusion 18 of the corrugated tube 10 is formed.

  As shown in FIGS. 2, 3, and 4, the first cover member 11 and the second cover member 12 are combined from both sides of the flat cable 9 and the braided wire 8, so that the rod-like protrusions of the second cover member 12 are assembled. 18 is passed through the gap of the braid of the braided wire 8 and through the through hole 17 of the first cover member 11. That is, the rod-shaped protrusion 18 passes between the braided wire 8, the plurality of flat cables 9, and the first cover member 11. Thereby, the rod-shaped protrusion 18 partitions the plurality of flat cables 9 individually in the corrugated tube 10.

  Further, the bar-shaped protrusion 18 is supported on both sides of the fixed portion on the base side and the portion passed through the through hole 17 on the tip side with respect to the lateral pressure received from the flat cable 9, and the bending is reduced. The

  Further, at the edge portion of the through hole 17 in the first cover member 11, a raised portion 171 is formed that fills the gap between the rod-shaped protrusion 18 of the second cover member 12 and the flat cable 9. Furthermore, the base portion of the rod-shaped protrusion 18 in the second cover member 12 is formed thicker than the portion that passes through the through hole 17 of the first cover member 11. Hereinafter, the root portion is referred to as a large diameter portion 181. The large diameter portion 181 narrows the gap between the rod-shaped protrusion 18 and the flat cable 9.

  Further, the raised portion 171 is formed such that its cross-sectional size is larger than the size of the stitches of the braided wire 8. Similarly, the large-diameter portion 181 is formed such that its cross-sectional size is larger than the size of the stitches of the braided wire 8. Therefore, as shown in FIGS. 2 and 3, the raised portion 171 and the large diameter portion 181 press the braided wire 8 toward the flat cable 9 and narrow the gap between the braided wire 8 and the flat cable 9.

  In addition, the tip of the rod-shaped protrusion 18 passed through the through-hole 17 is melt-processed, whereby the tip of the rod-shaped protrusion 18 is melted and the retaining portion 18A is wider than the diameter of the through-hole 17. It transforms and hardens. As a result, the first cover member 11 and the second cover member 12 are held in a combined state. The tip end of the rod-shaped protrusion 18 is melted by, for example, heating with a heater and subsequent cooling.

  Moreover, the 1st connection part 15 is projected and formed in the edge part of the both sides of the width direction in the 1st cover member 11 in several places. Similarly, the second connecting portion 16 is formed so as to protrude at a plurality of locations on both edges in the width direction of the second cover member 12. In this embodiment, the 1st connection part 15 and the 2nd connection part 16 are provided in the part which forms the protruding part 13 in the corrugated tube 10. FIG.

  The 1st connection part 15 and the 2nd connection part 16 are parts which hold | maintain the 1st cover member 11 and the 2nd cover member 12 which were combined from the both sides of the flat cable 9 and the braided wire 8 in the combined state.

  More specifically, the first connecting portion 15 is formed with a connecting hole 151 that is a through hole. On the other hand, a protruding connecting pin 161 is formed in the second connecting portion 16.

  As shown in FIGS. 2 and 3, the first cover member 11 and the second cover member 12 constituting the corrugated tube 10 are combined in a state in which the plurality of flat cables 9 and the braided wire 8 are sandwiched therebetween, whereby the second The connecting pin 161 of the connecting part 16 is inserted into the connecting hole 151 of the first connecting part 15. Then, the tip end portion of the connecting pin 161 passed through the connecting hole 151 is melt-processed, so that the tip end portion of the connecting pin 161 is deformed into a retaining portion 161A having a width wider than the diameter of the connecting hole 151. Harden. As a result, the first cover member 11 and the second cover member 12 are more firmly held in a combined state.

  The pair of the through-hole 17 and the rod-shaped protrusion 18 and the pair of the first connecting portion 15 and the second connecting portion 16 are provided at different positions in the longitudinal direction of the corrugated tube 10, for example, as shown in FIG. . Thereby, the 1st cover member 11 and the 2nd cover member 12 are the 1st connection part 15 and the 2nd connection part 16 in the several position disperse | distributed in the longitudinal direction, the pair of the through-hole 17 and the rod-shaped projection part 18, and. It is held in a cylindrical shape by a pair.

<Effect>
Since the wire harness 1 includes the braided wire 8, the friction resistance between the flat cable 9 and the braided wire 8 is small, and the flat cable 9 easily slides in the braided wire 8. Therefore, in the flat cylindrical corrugated tube 10, when the portion forming the flat surface is bent in the width direction, the flat cable 9 easily moves to the gap formed by the bending of the corrugated tube 10.

  However, in the wire harness 1, the rod-like protrusions 18 formed on the second cover member 12 constituting the corrugated tube 10 are passed through the through-holes 17 of the first cover member 11 and a plurality of the corrugated tubes 10. The flat cable 9 is divided individually. Furthermore, the rod-shaped protrusion 18 has the first cover member 11 and the second cover member 12 flattened by the melt-processed tip portion functioning as a retaining portion 18A from the through hole 17 of the first cover member 11. Hold in a cylindrically assembled state.

  Therefore, in the flat cylindrical corrugated tube 10, the rod-shaped protrusion 18 prevents the portion forming the flat surface from bending in the width direction itself, and the flat cables 9 move in the lateral direction and overlap each other. Stop that. Therefore, in the wire harness 1, there is no problem that the heat dissipation is reduced due to the flat cables 9 being stacked due to the bending of the corrugated tube 10.

  Further, in the wire harness 1, the rod-shaped protrusion 18 also serves as a lock function for holding the first cover member 11 on the second cover member 12 in addition to the function of preventing the plurality of flat cables 9 from overlapping each other. Moreover, it is easy to automate the process of melting the tip portion of the rod-like protrusion 18 that protrudes from the inside to the outside of the first cover member 11.

  For example, while the wire harness 1 is conveyed by a belt conveyor, the rod-shaped protrusion 18 and the connection pin 161 are brought close to the tip portion of the rod-shaped protrusion 18 and the tip portion of the connection pin 161 by being brought close to the heater supported by the elevator. It is conceivable to subject each tip portion to melt processing.

  Therefore, in the wire harness 1, it becomes possible to omit or simplify complicated processes such as taping work for holding the first cover member 11 and the second cover member 12 in a combined state in a cylindrical shape. .

  In addition, the rod-shaped protrusion 18 is passed through the gap between the stitches of the braided wire 8, thereby preventing the displacement of the braided wire 8 in the corrugated tube 10.

  Further, the raised portion 171 formed at the edge of the through-hole 17 and the large-diameter portion 181 formed thickly fill the gap between the rod-shaped protrusion 18 and the flat cable 9, thereby conducting heat conduction in the corrugated tube 10. A bad air layer becomes small, and the heat dissipation of the whole bundle | flux of the corrugated tube 10 improves more. Further, the braided wire 8 is pressed against the flat cable 9 by the raised portion 171 and the large diameter portion 181 and the shielding effect is enhanced.

It is also conceivable that the member is a shaped member.

  Moreover, although the corrugated tube 10 in which the rod-shaped protrusions 18 are formed is suitable for application to a wire harness including a braided wire 8 that collectively covers a plurality of electric wires, it is applicable to a wire harness that does not include the braided wire 8. It can also be considered. For example, it is also conceivable that the wire harness 1 shown above includes only the remaining components excluding the braided wire 8.
