The wiring member 100 is provided with a bus bar 10 and an electric wire 60 as a wiring material, and end portions of the bus bar 10 and the electric wire 60 are fastened and connected to the terminal portions 2 , 3 of the electrical connection box 1 . Thus, the wiring member 100 is wired to the electrical connection box 1 . The bus bar 10 and the electric wire 60 of the wiring member 100 are wiring materials for connecting from the electrical connection box 1 to a storage battery etc., and one of them is a positive electrode and the other is a negative electrode.

Fig. 2 is a perspective view of a wiring component. 3 is a perspective view of a state in which a ferrite case of a wiring member is removed.

As shown in FIGS. 2 and 3 , wiring member 100 including bus bar 10 and electric wire 60 has ferrite portion 70 . The ferrite part 70 is provided with a ferrite 71 covered with a ferrite case 72 made of insulating resin. The ferrite 71 is comprised by a pair of split ferrite 71a, 71b, and these split ferrite 71a, 71b are mutually combined and are formed in the shape of an ellipse ring.

The bus bar 10 and the electric wire 60 pass through the ring-shaped ferrite 71 , and the outer periphery thereof is covered with the ferrite 71 in the entire circumferential direction. Accordingly, even when a high-voltage/high-current current flows through the bus bar 10 and the electric wire 60 , the generation of noise can be suppressed by the ferrite 71 . In ferrite 71 , bus bar 10 and electric wire 60 are formed as parallel wiring portions 10A, 60A that are adjacent to each other and wired in parallel.

The electric wire 60 arranged in parallel with the bus bar 10 is constituted by an insulated electric wire whose outer periphery is covered with an insulating resin sheath, and a terminal metal fitting 61 having a hole 61 a is connected to one end of the electric wire 60 . The terminal metal fitting 61 provided at one end of this electric wire 60 is connected to the terminal portion 3 of the electrical connection box, and the other end of the electric wire 60 is connected to, for example, a terminal of a storage battery.

Fig. 4 is a perspective view of a bus bar constituting a wiring member.

As shown in FIG. 4 , the bus bar 10 is formed in a plate shape. The bus bar 10 is formed of, for example, a plate made of a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. One end of the bus bar 10 is a terminal connection portion (connection portion) 21 having a hole 21a, and the other end is a wire connection portion 22 having a hole 22a. In the bus bar 10 , the terminal connection portion 21 is connected to the terminal portion 2 of the electrical connection box 1 , and the electric wire 23 is connected to the electric wire connection portion 22 .

The other end side of the bus bar 10 having the wire connection portion 22 is formed as a parallel wiring portion 10A. In this parallel wiring portion 10A, the bus bar 10 passes through the ferrite 71 so that the width direction thereof is along the direction in which the bus bar 10 and the electric wires 60 are arranged.

The bus bar 10 has a horizontal bent portion 10B bent at right angles to the horizontal direction at an end portion of the parallel wiring portion 10A opposite to the electric wire connection portion 22 . Furthermore, the bus bar 10 has a horizontally extending portion 10C bent at the horizontally bent portion 10B and extending laterally with respect to the parallel wiring portion 10A. The end portion of the horizontally extending portion 10C on the side opposite to the parallel wiring portion 10A has a vertically bent portion 10D that is vertically bent. The terminal connection portion 21 side of the vertical bending portion 10D is a vertical extension portion 10E extending to the side opposite to the electric wire connection portion 22 . The end portion of the vertically extending portion 10E on the terminal connection portion 21 side has a vertically bent portion 10F that is vertically bent, and the side opposite to the vertically extending portion 10E of the vertically bending portion 10F becomes the terminal connection portion 21 . In this way, the bus bar 10 bends at the horizontal bending portion 10B and the vertical bending portions 10D and 10F to change the extending direction.

Fig. 5 is a perspective view of a bus bar connected to electric wires and covered by a case. 6 is a perspective view of a state in which a lid of a housing portion of a bus bar connected to an electric wire and covered by a case is opened.

As shown in FIGS. 5 and 6 , parts of the bus bar 10 other than the terminal connection portion 21 and a part of the vertically extending portion 10E are covered by the case 30 . The case 30 is composed of a first case 31 and a second case 32 .

The first case 31 is mounted on the lower side of the bus bar 10 , and the lower side of the bus bar 10 is covered by the first case 31 . The second case 32 is mounted on the upper side of the bus bar 10 , and the upper side of the bus bar 10 is covered by the second case 32 . The second case 32 is assembled to the first case 31 mounted on the bus bar 10 from the upper side. Thus, the first case 31 and the second case 32 are mounted on the bus bar 10 , and the bus bar 10 is covered by the case 30 constituted by the first case 31 and the second case 32 .

The housing 30 composed of the first housing 31 and the second housing 32 has a plurality of locking portions 37 . The locking portion 37 is composed of a locking claw 38 formed in the first housing 31 and a locking hole 39 formed in the second housing 32 . By assembling the second housing 32 to the first housing 31 mounted on the bus bar 10 , the locking claw 38 enters the locking hole 39 , thereby locking the locking portion 37 . As a result, the first housing 31 and the second housing 32 are locked in an assembled state.

Fig. 7 is a perspective view of the storage unit in a state where the lid is opened. 8 is a vertical cross-sectional view of the storage portion along the wiring direction in a state where the lid portion is closed.

As shown in FIGS. 7 and 8 , the case 30 includes a storage portion 40 having a storage space S, and the connecting portion between the electric wire connection portion 22 and the electric wire 23 of the bus bar 10 is accommodated in the storage space S of the storage portion 40 . The electric wire 23 is made of an insulated electric wire in which the outer periphery of a core wire is covered with a sheath made of insulating resin, and is connected to, for example, a terminal of a storage battery. The end portion of the electric wire 23 is connected to the terminal metal fitting 24 having the hole portion 24 a, and the end portion connected to the terminal metal fitting 24 is accommodated in the storage space S of the storage portion 40 .

The storage portion 40 has a bottom wall portion 41 , a peripheral wall portion 42 , and a cover portion 43 , and the storage space S is formed by the bottom wall portion 41 , the peripheral wall portion 42 , and the cover portion 43 . The bottom wall portion 41 is formed in the first case 31 , and the peripheral wall portion 42 and the cover portion 43 are formed in the second case 32 .

The peripheral wall portion 42 is constituted by two side wall portions 44 facing each other, and two end wall portions 45 connected to the ends of these side wall portions 44 and facing each other. The peripheral wall portion 42 is provided standing upright from the peripheral edge of the bottom wall portion 41 . A lead-out concave portion 45 a is formed in one end wall portion 45 constituting the peripheral wall portion 42 , and the electric wire 23 passes through the lead-out concave portion 45 a.

The cover portion 43 is integrally formed with a side wall portion 44 constituting the peripheral wall portion 42 via a hinge portion 46 . The cover portion 43 is rotatably connected to the side wall portion 44 by a hinge portion 46 . On the other side wall portion 44 constituting the peripheral wall portion 42, locking portions 44a are formed, and these locking portions 44a can be locked to the edge portion formed on the side opposite to the side where the hinge portion 46 is formed of the cover portion 43. In hole 43a.

Stud bolts 48 are erected on the bottom wall portion 41 constituting the storage portion 40 . The electric wire connection portion 22 of the bus bar 10 is accommodated in the accommodation space S in a state where the stud bolt 48 is inserted into the hole 22a. On this electric wire connection part 22, the terminal metal fitting 24 of the electric wire 23 into which the stud bolt 48 was inserted in the hole part 24a is superimposed. Then, the nut (fastener) 49 is screwed and fastened to the stud bolt 48 , whereby the electric wire connection portion 22 of the bus bar 10 and the terminal metal fitting 24 of the electric wire 23 are fastened.

The storage part 40 which accommodates the connection part of the bus bar 10 and the electric wire 23 close|closes the storage space S by turning the cover part 43 so that the upper part of the surrounding wall part 42 may be covered. At this time, the locking hole 43 a of the cover portion 43 is locked to the locking portion 44 a of the side wall portion 44 . Thereby, the rotation of the cover part 43 is restricted, and the state in which the storage space S is blocked is maintained.

In addition, a concave portion 51 into which the front end of the stud bolt 48 is inserted while closing the storage space S is formed in the lid portion 43 . An engaging wall 52 is formed on the peripheral portion of the concave portion 51 . When the cover portion 43 closes the storage space S, the engagement wall 52 has a protruding dimension such that the end surface thereof is disposed at a position facing the nut 49 fastened to the stud bolt 48 without a gap. Therefore, when the nut 49 is insufficiently fastened to the stud bolt 48 , the end surface of the engaging wall 52 of the cover portion 43 hits the nut 49 because the nut 49 floats. Therefore, the storage space S cannot be completely closed by the cover part 43, and the locking part 44a of the side wall part 44 cannot be locked in the locking hole 43a of the cover part 43, thereby, it is possible to detect the connection between the wire connecting part 22 of the bus bar 10 and The connection between the terminal metal pieces 24 of the electric wires 23 fails.

As described above, according to the wiring structure of the present embodiment, since the bus bar 10 and the electric wire 60 pass through the ring-shaped ferrite 71, the ferrite 71 can suppress the noise when the current flows through the bus bar 10 and the electric wire 60. produce.

In addition, the bus bar 10 is bent along the arrangement direction of the electric wires 60 between the terminal connection portion 21 connected to the electrical connection box 1 and the parallel wiring portion 10A inserted into the ferrite 71 . Therefore, it is possible to smoothly guide the bus bar 10 from the connection portion to the electrical junction box 1 into the ferrite 71 adjacent to the electric wire 60 . Therefore, a plurality of wiring materials composed of the electric wires 60 and the bus bars 10 can be smoothly wired into the electrical connection box 1 through the ring-shaped ferrite 71 .

In addition, since the case 30 covering the bus bar 10 has the storage portion 40 having the storage space S in which the connecting portion of the bus bar 10 and the terminal metal fitting 24 is housed, the bus bar 10 and the terminal metal fitting 24 can be connected together. 24 is stored and protected in the storage space S of the storage portion 40 . In addition, by opening the cover portion 43 , the connecting portion between the bus bar 10 and the terminal fitting 24 in the storage space S can be visually observed, and the presence or absence of the nut 49 and the connection state can be checked.

Furthermore, the cover part 43 has the engaging wall 52 which is arrange|positioned at the opposing position of the nut 49 without gap in the state which closed the storage space S. As shown in FIG. Therefore, when the nut 49 is loosened and floated, the engaging wall 52 hits the nut 49 and the lid 43 cannot be closed, thereby detecting a poor connection between the bus bar 10 and the terminal fitting 24 . In addition, since the cover portion 43 is rotatably provided on the peripheral wall portion 42, the number of components can be reduced.

In addition, the parallel wiring portion 10A of the bus bar 10 passes through the ferrite 71 so that the width direction is along the direction in which the electric wire 60 is arranged. Therefore, by wiring the wiring member 100 in the vehicle so that the arrangement direction of the bus bar 10 and the electric wires 60 is horizontal, the increase in height can be suppressed, and the narrow wiring of the vehicle with a limited height can be smoothly wired. in space.

Next, modified examples of the storage unit will be described.

Fig. 9 is a perspective view of a state in which a lid of a storage section according to a first modification is opened. 10 is a vertical cross-sectional view of the storage unit along the wiring direction in a state in which the cover of the storage unit according to the first modification is closed.

As shown in FIGS. 9 and 10 , 40A of accommodating portions according to the first modified example include lid portions 43 that are separate from peripheral wall portions 42 .

The peripheral wall portion 42 has one locking portion 44 a on one side wall portion 44 and two locking portions 44 a on the other side wall portion 44 . Moreover, the cover part 43 has one locking hole 43a in one edge part, and has two locking holes 43a in the other edge part.

In the storage portion 40A of this modified example, the locking portions 44 a of the peripheral wall portion 42 are respectively locked in the locking holes 43 a of the lid portion 43 by covering the upper portion of the peripheral wall portion 42 with the lid portion 43 . Thereby, the cover part 43 is assembled on the upper part of the surrounding wall part 42, and the storage space S is blocked by the cover part 43. As shown in FIG.

In the housing portion 40A, if the nut 49 is insufficiently fastened to the stud bolt 48 and the nut 49 floats, the end surface of the engaging wall 52 of the cover portion 43 hits the nut 49 . Therefore, the cover portion 43 cannot be assembled to the peripheral wall portion 42 , and a poor connection between the electric wire connection portion 22 of the bus bar 10 and the terminal metal fitting 24 of the electric wire 23 can be detected. In particular, in the accommodating portion 40A, since the end surface of the engaging wall 52 of the cover portion 43 hits the nut 49, the cover portion 43 falls off from the peripheral wall portion 42, so that the wire connection of the bus bar 10 can be more accurately detected. The connection between the portion 22 and the terminal metal piece 24 of the electric wire 23 is poor.

Fig. 11 is a perspective view of a storage unit according to a second modified example. Fig. 12 is a side view of a storage unit according to a second modified example. Fig. 13 is a side view of a storage unit according to a second modification.

As shown in FIG. 11 and FIG. 12 , in the housing 30 of the second modified example, an electric wire drawing guide 84 protruding from the end wall portion 45 to the extending direction of the electric wire 23 is provided, and the electric wire 23 can be bound by a binding band 80 . It is fixed on the wire lead-out guide 84.

The binding band 80 has a band part 82 and a head part 81. The band part 82 is inserted into the head part 81, and the engagement claw (not shown) which prevents movement in the return direction is provided. The lead-out guide 84 has a curved surface 86 bound together with the electric wires 23 by the belt portion 82 of the binding tape 80 , and end portions 87 , 88 formed at both ends of the curved surface 86 . Through-holes, which are smaller than the head portion 81 of the binding band 80 , are formed in the end portions 87 and 88 , through which the band portion 82 penetrates toward the electric wire side. Therefore, when the binding band 80 rotates in the outer peripheral direction of the electric wire 23, the head part 81 abuts the side surface 87a of the end part 87 or the side surface 88a of the end part 88, and movement in the rotation direction is restricted.

The binding band 80 may move along the outer circumference of the electric wire 23 due to the vibration of the vehicle. Therefore, as shown in FIG. 13 , when other parts 90 are provided near the wire drawing guide 84, if the movement of the head 81 is not restricted, there is a possibility that the head 81 interferes with the other parts 90, but In the case 30 of the second modified example, the head 81 does not move any further when it comes into contact with the side surface 88 a of the end portion 88 , so that it is possible to prevent the head 81 from interfering with another member 90 .

In the above-mentioned embodiment, the bus bar 10 is passed through the ferrite 71 together with the electric wires 60 so that the width direction is along the alignment direction with the electric wires 60. However, as shown in FIG. The direction is perpendicular to the arrangement direction of the electric wires 60 through the ferrite 71 . In this case, when the bus bar 10 and the electric wire 60 are mounted on the vehicle so that the alignment direction of the electric wire 60 is along the horizontal direction, even when vibration is applied in the vertical direction of the vehicle, the bus current caused by the vibration can be suppressed. Displacement of the bar 10, and the bus bar 10 can be configured in a stable state.

In addition, this invention is not limited to the above-mentioned embodiment, Deformation, improvement, etc. are possible suitably. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-mentioned embodiment may be arbitrary as long as the present invention can be realized, and are not limited thereto.
