However, in the manufacture of the shielded conductive path as described above, there is a problem that the manufacturing work becomes difficult because the electric wire must be inserted into a very long pipe extending from the front part to the rear part 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, the electric wire is placed along one of the divided bodies, and then the other divided body is attached to the one divided body. By combining, the electric wire is housed in the pipe, so that the work of passing the electric wire through the pipe becomes unnecessary, and the work load can be reduced. However, when the combined work of the two divided bodies is performed, if the relative position of the divided bodies with respect to the electric wire is not determined, there is a problem that the two divided bodies are displaced in the axial direction and it is difficult to work. It is also necessary to take measures to prevent the two split bodies from shifting their positions after being united.

The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a shielded conductive path capable of easily performing a manufacturing operation and preventing misalignment.

Shield conductor path of the present invention comprises a pair of divided bodies with a split end in the axial direction, it comprises a tubular shield pipe covering the periphery of the electric wire, and a positioning member attached to the electric wire, the positioning The member has a mounting piece to which the electric wire is attached.

According to the above configuration, for example, the electric wire is accommodated in the shield pipe by arranging the electric wire inside one of the pair of divided bodies and then combining the other divided body with the one divided body. Since it is in the state of being used, it is not necessary to pass the electric wire through the shield pipe.

In addition, the positioning member is attached to the electric wire .

It is a side view which shows the state which the positioning member was attached to the electric wire. Further, it is a side view which shows the state in which a pair of divided bodies are united. Further, it is a side view which shows the state which the braided member is attached. It is a side view which shows the structure in the shield pipe in FIG. FIG. 3 is a cross-sectional view taken along the line AA of FIG. It is a perspective view of the positioning member. It is a side view of the positioning member.

Preferred embodiments of the present invention are shown below.
It is preferable that the divided ends of the pair of divided bodies are closed by a welded portion.

It is good to have. By including a single wire in the electric wire, the cost can be suppressed at low cost, and the diameter of the single wire portion can be reduced. In addition, such a small diameter single wire is covered with a shield pipe over the entire length to ensure stable and reliable protection. Further, the circumference of the connection area between the single wire and the stranded wire is also protected by being covered with a shield pipe. In particular, in the case of the present invention, after the connection work of the connection area 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 area is post-inserted into the shield pipe. No need to do tedious work.

The positioning member has a tubular portion having a tubular shape along the inner circumference of the shield pipe, a locking protrusion is provided on the outer circumference of the tubular portion, and the pair of divided bodies are engaged with the above. It is preferable that a locking receiving portion for receiving the stop collision portion is provided. Since the locking protrusion is provided on the outer periphery of the tubular portion, the locking protrusion does not protrude inside the tubular portion and narrow the wiring space for the electric wire in the shield pipe.

As shown in FIG. 5, a 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 by knitting a conductive metal fine wire (for example, copper) into a mesh shape to form a tubular shape. A metal foil or the like may be wound instead of the braided member 15.

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

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 as each other. 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 extending along the length direction of the shield pipe 11. Both divided bodies 12 are united by abutting the divided ends 17 of each other. In the following, the state in which the divided ends 17 of the two divided bodies 12 are abutted against each other is referred to as a combined portion 18.

Of the peripheral edge portions of both the divided bodies 12, one end edge portion is located inside the other end edge portion (diametrically inside the shield pipe 11), and both end edge portions overlap each other in the inner and outer directions. As a result, the lap region 19 is formed. One end edge of the wrap region 19 is provided with a protective wall 21 that projects into the shield pipe 11 and extends so as to cover the other end edge from the inside. In the case shown in FIG. 6, the protective wall 21 is provided on the left edge portion of the upper split body 12 shown on the left side and the right edge portion of the lower split body 12 shown on the right side, respectively, of the upper split body 12.

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 region 19 of the two divided bodies 12 by welding such as laser welding applied to the outside. ing. The mating portion 18 of the split ends 17 of both split bodies 12 is closed by the welded portion 24. By forming the welded portion 24 by laser welding or the like, it is possible to avoid forming a raised shape on the outer periphery of the shield pipe 11, and it is possible 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 at both ends in the length direction and substantially in the center in the circumferential direction of the divided body 12. The locking receiving portions 25 of the two divided bodies 12 are arranged so as to face both radial ends (upper and lower ends of FIG. 6) of the shield pipe 11 at the time of coalescence. A locking protrusion 84, which will be described later, of the positioning member 80 can be fitted to the locking receiving portion 25.

Subsequently, 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 in the length direction of the shield pipe 11. As shown in FIGS. 7 and 8, the positioning member 80 has a cylindrical portion 81 having both ends open in the axial direction (the length direction of the shield pipe 11), more specifically, a cylindrical portion 81 and a tubular portion 81.

It has a flat cylindrical locking protrusion 84 that protrudes from the lower end portion shown on the outer peripheral surface of the shaped portion 81 and the upper end portion shown on the drawing. The above-mentioned two electric wires 60 are inserted into the tubular portion 81, and more specifically, the coating 66 at the other end of the stranded wire 62 in the length direction is inserted into the two electric wires 60.

The locking protrusions 84 are arranged in pairs at both ends in the radial direction (upper and lower ends in the drawing) of the tubular portion 81. The locking protrusion 84 has a protruding dimension slightly exceeding the depth dimension of the locking receiving portion 25, the protruding end face is formed flat, and the outer peripheral edge of the protruding end face is chamfered over the entire circumference. There is.

As shown in FIG. 5, the end portion of the shield pipe 11 in the length direction is externally fitted to the tubular portion 81, and the locking protrusion 84 is elastically fitted to the locking receiving portion 25 as shown in FIG. By inserting it, 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 end portions shown in the drawing 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 faces the end edge of the shield pipe 11 in the lengthwise direction so as to be abuttable, and it is possible to define the mounting position of the shield pipe 11 with respect to the positioning member 80.

As shown in FIG. 6, a pair of relief recesses 85 for avoiding interference with the protective wall 21 of the shield pipe 11 are provided at both radial ends (left and right ends in the drawing) of the tubular portion 81 so as to project inward. .. The relief recess 85 is provided so as to extend in the length direction to a portion of the tubular portion 81 other than the step portion 82, and bulges inward so as to have the same thickness as the adjacent portion in the circumferential direction. There is. As shown in FIG. 7, of the stepped portion 82 of the tubular portion 81, a thick portion 86 that is built up inside in a shape corresponding to the relief recess 85 is provided at a position continuous with the relief recess 85. There is. The protective wall 21 of the divided body 12 is arranged on the thick portion 86 so as to be in contact with each other. 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 is connected to the inner end of the curved portion and extends linearly while being separated from the curved surface 22 of the protective wall 21. It has a part 88 and.

As shown in FIG. 8, the mounting piece 83 has a total length slightly exceeding the total length (length in the axial direction) of the tubular portion 81, and is once raised toward the central axis from a portion connected to one end of the tubular portion 81. After that, it is in the form of extending straight toward the tip. As shown in FIG. 6, the mounting piece 83 has a curved cross-sectional arc shape along the outer circumference of the electric wire 60, and the upper surface (the surface facing the central axis side) shown is a curved support surface 79 that supports the electric wire 60. ing. With the electric wires 60 mounted on the support surface 79 of the mounting piece 83, the tape 50 is wound together from the lower surface of the mounting piece 83 over the outer circumferences of the two electric wires 60. As a result, the electric wire 60 is attached and fixed to the attachment piece 83. The two electric wires 60 (stranded wires 62) are tape-wound between the two electric wires 60 (twisted wires 62) and held in a state of being stacked in the vertical direction shown in the drawing.

Next, an example of the method for manufacturing the shielded conductive path 10 of the first embodiment will be described.
Prior to the union work of the two split 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, and the overlapped portion is soldered to both ends in the length direction of the single wire 61. A stranded wire 62 is connected to the stranded wire 62 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 of the stranded wire 62 in the length direction is connected to the corresponding device-side connectors 94 and 95.

Subsequently, as shown in FIG. 2, the mounting piece 83 of the positioning member 80 is attached to a predetermined position of the coating 66 of the stranded wire 62 located on both sides of the single wire 61 via the tape 50. The positioning members 80 are attached in pairs on both sides in the length direction of the electric wire 60, and the separation distance between the attachment positions of both positioning members 80 is set to a length corresponding to the total length of the shield pipe 11. As a result, the semi-finished shielded conductive path 10A is formed.

Next, of the two divided bodies 12, one of the divided bodies 12 is placed along the electric wire 60, and both ends of the one divided body 12 in the length direction are formed in a half-circumferential region of the tubular portion 81 of the corresponding positioning member 80. It fits outside (for example, the lower half area). Then, the locking protrusion 84 of one of the split bodies 12 is fitted and locked to the locking receiving portion 25, whereby the one split body 12 is positioned with respect to the electric wire 60.

Further, while the other split body 12 is run along the electric wire 60 from the side opposite to the one split body 12, both ends of the other split body 12 in the length direction are arranged with the tubular portions 81 of the positioning member 80 corresponding to each. Fits into the remaining half-circumferential region (eg, upper half region) of. Similar to the above, the locking protrusion 84 of the other split body 12 is fitted and locked to the locking receiving portion 25, so that the other split body 12 is positioned with respect to the electric wire 60. When the divided ends 17 of the two divided bodies 12 are abutted against each other along the axial direction, the lap regions 19 of the two divided bodies 12 are in a state of overlapping each other in the inner and outer directions with the protective wall 21 inside.

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

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

Next, as shown in FIG. 4, both ends of the shield pipe 11 in the length direction are covered with the braided members 15 and fixed with the metal band 16. As a result, the stranded wire 62 arranged between the device-side connectors 94 and 95 and the shield pipe 11 is shielded by the braided member 15.

After that, 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 circular shape similar to the conventional one, the pipe bender machine conventionally used can be used as it is. Further, since the pair of divided bodies 12 are held in a state of being tightly fixed by the welded portion 24, it is possible to reliably prevent a situation in which the mouth of the mating portion 18 is inadvertently opened due to the bending process. .. As a result, it is possible to prevent the electric wire 60 from being exposed and noise from leaking from the shield pipe 11. Thus, the shield pipe 11 is plastically deformed into a predetermined shape by bending, and the pair of divided bodies 12 are held in a united state.

As described above, the shield conductive path 10 of the first embodiment is composed of a pair of divided bodies 12 having divided ends 17 along the length direction (axial direction), and is a tubular shield that covers the periphery of the electric wire 60. It includes a pipe 11 and a positioning member 80 that is locked to a pair of divided bodies 12 and attached to an electric wire 60. According to this configuration, since the electric wires 60 are housed in the shield pipe 11 formed in a tubular shape by combining the two divided bodies 12 with the electric wires 60 in between, the electric wires 60 are contained in the shield pipe 11. The work of passing through is unnecessary. Further, since the positioning member 80 is locked to the divided body 12 while being attached to the electric wire 60, the relative position of the divided body 12 with respect to the electric wire 60 is held at a fixed position, so that the two divided bodies 12 are united. It is possible to prevent the position from shifting at the 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, there is an advantage that the positioning member 80 can suppress the misalignment of the two split bodies 12 during the welding work. large. Further, since the welded portion 24 is formed at the mating portion 18 of the split ends 17 of the two split bodies 12, a gap is generated between the split ends 17 of the two split bodies 12 when the shield pipe 11 is bent. It can be reliably prevented. As a result, the reliability of preventing exposure and noise leakage of the electric wire 60 is enhanced.

Further, since the pair of divided bodies 12 have a wrap area 19 that overlaps in the inner and outer directions, a protective wall 21 that covers the combined portion 18 of the divided ends 17 from the inside of the shield pipe 11 is provided inside the wrap area 19. , It is possible to prevent the thermal influence caused by the welding work of the welded portion 24 from reaching the electric wire 60 in the shield pipe 11.

Further, the electric wire 60 is composed of a single wire 61 and a stranded wire 62 connected to the end portion of the single wire 61 in the length direction, the shield pipe 11 covers the single wire 61 over the entire length, and the connection region 67 between the single wire 61 and the stranded wire 62. Since it covers the periphery, the single wire 61 having a relatively small diameter and the connection area 67 having a weak strength are stably protected by the shield pipe 11.

Further, the positioning member 80 has a tubular portion 81 having a tubular shape along the inner circumference of the shield pipe 11, and a step on the outer periphery of the tubular portion 81 facing the end edge of the pair of divided bodies 12 in the length direction. Since the portion 82 is projected, even if an edge is formed at the axial end edge of the divided body 12, the edge can be hidden by the stepped portion 82 so that the edge interferes with peripheral parts and the like. It can be avoided.

Furthermore, since the locking protrusion 84 is provided on the outer periphery of the tubular portion 81 and the locking receiving portion 25 for receiving the locking protrusion 84 is provided on the divided body 12, the inner circumference of the tubular portion 81 is further provided. 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.
