Description

  The present invention relates to a shield conductive path having a shield function.

  Conventionally, in a vehicle such as a hybrid vehicle, for example, an electric wire is wired under the floor of the vehicle so as to connect a device such as a high voltage battery provided at the rear of the vehicle and a device such as an inverter or a fuse box provided at the front of the vehicle.

Yes.

JP 2004-171952 A

  However, in the manufacture of the shield conductive path as described above, there is a problem that the manufacturing operation becomes difficult because an electric wire must be inserted through a very long pipe extending from the front to the rear of the vehicle.

  On the other hand, if the pipe is composed of a pair of divided bodies that are divided along the axial direction, after placing the electric wire along one divided body, the other divided body is attached to the one divided body. By merging, since the electric wire is housed in the pipe, the operation of passing the electric wire through the pipe becomes unnecessary, and the work load can be reduced. However, if the relative position of the divided body with respect to the electric wire is not fixed when performing the combined operation of both divided bodies, there is a problem that both the divided bodies are displaced in the axial direction and are difficult to work. It is also necessary to take measures to prevent the two divided bodies from being displaced after being combined.

  The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a shield conductive path that can be easily manufactured and that can prevent displacement.

  The shield conductive path of the present invention comprises a pair of split bodies having split ends along the axial direction, and includes a cylindrical shield pipe that covers the periphery of the electric wire, and a positioning member attached to the electric wire, and the positioning member Has a cylindrical portion that forms a cylindrical shape along the inner periphery of the shield pipe, and a stepped portion that opposes the axial end edges of the pair of divided bodies on the outer periphery of the cylindrical portion. It is characterized by its protruding location.

  According to the above configuration, for example, the electric wire is accommodated in the shield pipe by fitting the electric wire inside one of the divided bodies and then combining the other divided body with the one divided body. Therefore, the work of passing the electric wire through the shield pipe becomes unnecessary.

  A positioning member is attached to the electric wire. The step portion opposes the edge in the length direction of the pair of divided bodies (shield pipes) so as to come into contact with each other, and can define the attachment position of the shield pipe with respect to the positioning member. Even if an edge is formed at the axial end edge of the divided body, the edge can be hidden by the stepped portion, and the edge can be prevented from interfering with peripheral components and the like.

It is the schematic which shows the wiring path | route of the shield conductive path which concerns on Example 1 of this invention. It is a side view which shows the state in which the positioning member was attached to the electric wire. Furthermore, it is a side view which shows the state which a pair of division body united. Furthermore, it is a side view which shows the state by which the braided member was adhered. It is a side view which shows the structure in the shield pipe in FIG. FIG. 4 is a sectional view taken along line AA in FIG. 3. It is a perspective view of a positioning member. It is a side view of a positioning member.

Preferred embodiments of the present invention are shown below.
The split ends of the pair of split bodies may be closed by welds. According to this, since the closed state of the split ends of both split bodies is firmly maintained by the welded portion, for example, when bending the shield pipe, it is possible to prevent a gap from being generated between the split ends of both split bodies. can do. In particular, in the case of the present invention, since the positional deviation between the two divided bodies is regulated by the positioning member, the welding operation of the welded portion can be performed smoothly.

  The pair of divided bodies may have a wrap region that overlaps inward and outward directions, and a protective wall may be provided on the inner side of the wrap region to cover the mating portion of the divided ends from the inner side of the shield pipe. Since the protective wall covers the mating portion of the split ends from the inside of the shield pipe, it is possible to prevent the thermal influence caused by the welding operation of the welded portion from reaching the electric wires in the shield pipe.

  The electric wire consists of a single wire and a stranded wire connected to the lengthwise end of the single wire, and the shield pipe covers the single wire over its entire length and covers the periphery of the connection region between the single wire and the stranded wire. It is good to have. By including a single wire in the electric wire, the cost can be reduced at a low cost, and the diameter of the single wire portion can be reduced. Further, such a single wire having a small diameter is covered with a shield pipe over the entire length, so that it can be stably and reliably protected. Furthermore, the periphery of the connection region between the single wire and the stranded wire is also protected by being covered with the shield pipe. In particular, in the case of the present invention, after the connection work of the connection region between the single wire and the stranded wire is completed, the two divided bodies can be combined to form a shield pipe, so that the connection region is inserted into the shield pipe later. There is no need for troublesome work.

  The positioning member has a cylindrical portion that forms a cylindrical shape along the inner periphery of the shield pipe, and a locking projection is provided on the outer periphery of the cylindrical portion. It is preferable that a locking receiving portion for receiving the stopping protrusion is provided. Since the locking projection is provided on the outer periphery of the cylindrical portion, the locking projection does not protrude inside the cylindrical portion and the wiring space of the electric wire in the shield pipe is not reduced.

  As shown in FIG. 5, the portion of the two electric wires 60 other than the other end in the length direction of the stranded wire 62 is not surrounded by the shield pipe 11 but is collectively surrounded by the braided member 15. The braided member 15 is formed in a cylindrical shape by braiding conductive metal wires (for example, copper) into a mesh shape. In place of the braided member 15, a metal foil or the like may be wound.

  One end in the length direction of the braided member 15 is fixed to the shield shells 98 and 99 of the device side connectors 94 and 95 so as to be conductive, and the other end in the length direction of the braided member 15 is covered on the outer peripheral surface of the end of the shield pipe 11. It is attached and crimped by a metal band 16 so as to be conductive.

  The pair of divided bodies 12 constituting the shield pipe 11 can be divided along the length direction (axial direction) of the shield pipe 11 and have a semicircular cross section and the same shape. The divided body 12 is formed by extrusion molding. As shown in FIG. 6, both ends in the circumferential direction of the divided body 12 are divided ends 17 that extend along the length direction of the shield pipe 11. Both divided bodies 12 are joined together by abutting their divided ends 17 together. Hereinafter, a state in which the divided ends 17 of the two divided bodies 12 are abutted with each other is referred to as a matching portion 18.

  Of the two circumferential edges of both divided bodies 12, one edge is located inside the other edge (inward in the radial direction of the shield pipe 11), and both edges overlap each other in the inner and outer directions. Thus, the wrap region 19 is formed. One end edge of the wrap region 19 is provided with a protective wall 21 that protrudes into the shield pipe 11 and extends to cover the other end edge from the inside. In the case shown in FIG. 6, the protective walls 21 are respectively provided on the left edge portion of the upper divided body 12 in the drawing and the right edge portion of the lower divided body 12 in the illustrated right side.

The protective wall 21 has a flat contact surface 23 that comes into contact with the inner surface of the other edge of the divided body 12.

  The mating portion 18 of the split ends 17 of both split bodies 12 is covered with a protective wall 21 from the inside. The outer surface of the other edge of the wrap region 19 of the divided body 12 is substantially flush with the adjacent outer circumferential surface of the divided body 12, and maintains the perfect circular shape of the outer circumference of the shield pipe 11 as a whole. is doing.

  A welded portion 24 (not shown in detail but see FIGS. 3 and 4) is formed over the entire length of the mating portion 18 of the lap regions 19 of the two divided bodies 12 by welding such as laser welding applied to the outside. ing. The joining portion 18 of the split ends 17 of both split bodies 12 is closed by a welded portion 24. By forming the welded portion 24 by laser welding or the like, it is possible to avoid the formation of a raised shape on the outer periphery of the shield pipe 11 and to maintain the perfect circular shape on the outer periphery of the shield pipe 11. it can.

  As shown in FIG. 6, circular locking receiving portions 25 are provided through both ends of the divided body 12 in the length direction and substantially in the circumferential direction. The latch receiving portions 25 of the two divided bodies 12 are arranged to face both ends in the radial direction of the shield pipe 11 (upper and lower ends in FIG. 6) when combined. A locking protrusion 84 (described later) of the positioning member 80 can be fitted into the locking receiving portion 25.

  Next, the positioning member 80 will be described. The positioning member 80 is made of synthetic resin, and is provided in pairs at positions corresponding to both ends of the shield pipe 11 in the length direction. As shown in FIGS. 7 and 8, the positioning member 80 has a cylindrical shape in which both ends in the axial direction (length direction of the shield pipe 11) are open, specifically, a cylindrical cylindrical portion 81, and a cylindrical portion 81. A rib-shaped stepped portion 82 projecting along the circumferential direction at the end of the outer periphery, a strip-shaped mounting piece 83 projecting in parallel with the axial direction from one end of the illustrated lower side portion of the tubular portion 81, and a tube And a flat columnar locking projection 84 protruding from the lower end portion and the upper end portion of the figure. The two electric wires 60 described above are inserted inside the cylindrical portion 81, and specifically, the covering 66 at the other end in the length direction of the stranded wire 62 is inserted through the two electric wires 60.

  The locking projections 84 are arranged in pairs at both ends in the radial direction of the cylindrical portion 81 (upper and lower ends in the drawing). The locking projection 84 has a protruding dimension that slightly exceeds the depth dimension of the locking receiving portion 25, the protruding end surface is formed flat, and the outer peripheral edge of the protruding end surface is chamfered over the entire circumference. Yes.

  As shown in FIG. 5, the end portion in the length direction of the shield pipe 11 is externally fitted to the cylindrical portion 81, and the locking projection 84 is elastically fitted to the locking receiving portion 25 as shown in FIG. As a result, the positioning member 80 is locked to the shield pipe 11.

  The step portion 82 is provided at a portion excluding the upper and lower ends in the figure in the circumferential direction. The locking protrusion 84 is visible between the step portions 82 on both the left and right sides when viewed from the axial direction. As shown in FIG. 5, the stepped portion 82 opposes the edge in the length direction of the shield pipe 11 so as to be able to come into contact with it, and can define the attachment position of the shield pipe 11 with respect to the positioning member 80.

  As shown in FIG. 6, a pair of relief recesses 85 that avoid interference with the protective wall 21 of the shield pipe 11 are provided projecting inward at both ends in the radial direction of the cylindrical portion 81 (both left and right ends in the drawing). . The relief recess 85 extends in the length direction at a portion of the tubular portion 81 excluding the step portion 82, and has a form that bulges inward so as to continue with the same thickness as the adjacent portion in the circumferential direction. Yes. As shown in FIG. 7, in the stepped portion 82 of the tubular portion 81, a thick portion 86 that is built up inward in a shape corresponding to the relief recess 85 is provided at a position continuous with the relief recess 85. Yes. The protective wall 21 of the divided body 12 is disposed on the thick portion 86 so as to be able to come into contact therewith. As shown in FIG. 6, the relief recess 85 includes a curved portion 87 that curves along the curved surface 22 of the protective wall 21, and a straight line that extends linearly while being connected to the inner end of the curved portion and being separated from the curved surface 22 of the protective wall 21. Part 88.

  As shown in FIG. 8, the attachment piece 83 has a total length that slightly exceeds the total length (axial length) of the cylindrical portion 81, and is once raised from the portion connected to one end of the cylindrical portion 81 to the central axis side. After that, it is configured to extend straight toward the tip. As shown in FIG. 6, the mounting piece 83 has a cross-sectional arc shape that curves along the outer periphery of the electric wire 60, and the upper surface (the surface facing the central axis) in the figure is a curved support surface 79 that supports the electric wire 60. ing. In a state where the electric wire 60 is placed on the support surface 79 of the attachment piece 83, the tape 50 is collectively wound around the outer periphery of the two electric wires 60 from the illustrated lower surface of the attachment piece 83. Thereby, the electric wire 60 is attached and fixed to the attachment piece 83. In addition, the two electric wires 60 (stranded wire 62) are taped between the attachment pieces 83 and held in a state where they are stacked in the vertical direction in the figure.

Next, an example of a manufacturing method of the shield conductive path 10 according to the first embodiment will be described.
Prior to the union operation of the two divided bodies 12, the exposed region of the core wire 65 of the stranded wire 62 and the exposed region of the core wire 63 of the single wire 61 are overlapped with each other, solder is applied to the overlapped portion, and both ends of the single wire 61 in the length direction Then, a stranded wire 62 is connected to form a connection region 67, and a protective member 68 is attached so as to cover the outer periphery of the connection region 67. Further, at an appropriate time, one end in the length direction of the stranded wire 62 is connected to the corresponding device-side connectors 94 and 95.

  Subsequently, as shown in FIG. 2, the attachment pieces 83 of the positioning member 80 are attached to the predetermined positions of the covering 66 of the stranded wire 62 located on both sides of the single wire 61 via the tape 50. The positioning member 80 is attached to both sides of the electric wire 60 in the length direction, and the distance between the attachment positions of the positioning members 80 is set to a length corresponding to the entire length of the shield pipe 11. Thereby, the shield conductive path 10A in a semi-finished state is formed.

  Next, the half-circumferential region of the cylindrical portion 81 of the positioning member 80 corresponding to each of the both end portions in the length direction of the one divided body 12 while keeping one divided body 12 along the electric wire 60 out of the two divided bodies 12. (For example, the lower half region). Then, the locking projection 84 of the one divided body 12 is fitted and locked to the locking receiving portion 25, whereby the one divided body 12 is positioned with respect to the electric wire 60.

  In addition, while the other divided body 12 is placed along the electric wire 60 from the side opposite to the one divided body 12, both end portions in the length direction of the other divided body 12 are respectively corresponding to the cylindrical portions 81 of the positioning members 80. Are fitted on the remaining half-circumferential region (for example, the upper half region). Similarly to the above, the other protrusion 12 is positioned with respect to the electric wire 60 by fitting and locking the locking protrusion 84 of the other divided body 12 to the locking receiving portion 25. When the divided ends 17 of the two divided bodies 12 are abutted with each other along the axial direction, the wrap regions 19 of the two divided bodies 12 overlap each other in the inner and outer directions with the protective wall 21 inside.

  Subsequently, the welded portion 24 is formed on the mating portion 18 of the split ends 17 of both split bodies 12 by performing laser welding or the like continuously from the outside over the entire length. At this time, as shown in FIG. 6, since a protective wall 21 is interposed between the mating portion 18 of the split ends 17 of both split bodies 12 and the electric wire 60 in the shield pipe 11, the thermal process of welding is performed. An influence is interrupted | blocked by the protective wall 21, and the electric wire 60 is protected.

  In this way, the pair of divided bodies 12 are joined together via the mating portion 18 of the divided end 17, and as shown in FIG. 3, a cylindrical shield pipe 11 extending linearly is formed. In the shield pipe 11, the single wire 61 is accommodated over the entire length, and further, the connection region 67 between the single wire 61 and the stranded wire 62 and the other end portion in the length direction of the stranded wire 62 are accommodated.

  Next, as shown in FIG. 4, the braided member 15 is put on both ends in the length direction of the shield pipe 11 and fixed with the metal band 16. Thereby, the stranded wire 62 routed between the device-side connectors 94 and 95 and the shield pipe 11 is shielded by the braided member 15.

  Thereafter, the shield pipe 11 is bent into a predetermined shape. At that time, since the outer shape of the shield pipe 11 is a perfect circle shape similar to the conventional one, the pipe bender machine used conventionally can be used as it is. In addition, since the pair of divided bodies 12 are held in a state of being firmly fixed by the welded portion 24, it is possible to reliably prevent a situation where the mouth of the mating portion 18 is inadvertently opened due to bending. . As a result, exposure of the electric wire 60 from the shield pipe 11 and noise leakage can be prevented. Thus, the shield pipe 11 is plastically deformed into a predetermined shape by bending, and the pair of divided bodies 12 are held in the combined state.

  As described above, the shield conductive path 10 according to the first embodiment includes the pair of divided bodies 12 having the divided ends 17 along the length direction (axial direction), and covers the periphery of the electric wire 60. A pipe 11 and a positioning member 80 which is locked to the pair of divided bodies 12 and attached to the electric wire 60 are provided. According to this configuration, since the two divided bodies 12 are combined with the electric wire 60 interposed therebetween, the electric wire 60 is accommodated in the shield pipe 11 formed in a cylindrical shape. No need to pass through. Moreover, since the relative position of the division body 12 with respect to the electric wire 60 is hold | maintained in a fixed position by the positioning member 80 being latched by the division body 12 in the state attached to the electric wire 60, both division bodies 12 are united work. It is possible to prevent displacement from occurring after time or after coalescence.

  In particular, in the case of the first embodiment, since the split ends 17 of the pair of split bodies 12 are closed by the welded portion 24, the merit that the positional deviation between the split bodies 12 can be suppressed by the positioning member 80 during the welding operation is as follows. large. In addition, since the welded portion 24 is formed at the mating portion 18 of the split ends 17 of both the split bodies 12, a gap is generated between the split ends 17 of the split bodies 12 when the shield pipe 11 is bent. It can be surely prevented. As a result, the reliability of preventing the exposure of the electric wire 60 and noise leakage is enhanced.

  Further, the pair of divided bodies 12 has a wrap region 19 that overlaps inward and outward directions, and a protective wall 21 is provided inside the wrap region 19 to cover the mating portion 18 of the divided end 17 from the inside of the shield pipe 11. The thermal influence resulting from the welding operation of the welded portion 24 can be prevented from reaching the electric wire 60 in the shield pipe 11.

  The electric wire 60 includes a single wire 61 and a stranded wire 62 connected to the lengthwise end of the single wire 61, and the shield pipe 11 covers the single wire 61 over the entire length and is connected to the connection region 67 of the single wire 61 and the stranded wire 62. Since the periphery is covered, the single wire 61 having a relatively small diameter and the connection region 67 that is weak in strength are stably protected by the shield pipe 11.

  Further, the positioning member 80 has a cylindrical portion 81 that forms a cylinder shape along the inner periphery of the shield pipe 11, and a step that faces the longitudinal edges of the pair of divided bodies 12 on the outer periphery of the cylindrical portion 81. Since the portion 82 is projected, even if an edge is formed on the axial end edge of the divided body 12, the edge can be hidden by the step portion 82, and the edge can interfere with peripheral parts and the like. It can be avoided.

  Furthermore, the locking projection 84 is provided on the outer periphery of the cylindrical portion 81, and the latch receiving portion 25 that receives the locking projection 84 is provided on the divided body 12. Unlike the case where the locking protrusion 84 is provided, the wiring space of the electric wire 60 in the shield pipe 11 is not restricted and the space efficiency is excellent.
