Description

The present invention relates to a wiring structure.

For example, electrical connection boxes such as junction blocks mounted on vehicles such as automobiles may use bus bars for their internal wiring (see, for example, Patent Document 1). The electrical connection box also has terminals to which wiring material from the outside is connected. Electric wires are used as the wiring material connected to these terminals because of ease of connection.

JP 2021-151054 A

In vehicles that use electric motors as their drive source, such as electric vehicles and hybrid vehicles, large-diameter electric wires are routed to an electrical junction box to carry high-current, high-voltage current. When passing high-current, high-voltage current through electric wires, it is necessary to pass the positive and negative electric wires through a ring-shaped ferrite to suppress noise.

However, it is difficult to bend large-diameter electric wires easily, which makes it difficult to pass the positive and negative electric wires through the ring-shaped ferrite and route them to the electrical junction box.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a wiring structure that allows multiple wiring materials to be easily routed to an electrical connection box by passing them through a ring-shaped ferrite.

Specific embodiments of the present invention are described below with reference to the drawings.

FIG. 1 is a perspective view of a connection portion of a wiring member in an electric junction box to which a wiring structure according to this embodiment is applied.
As shown in Fig. 1, the wiring structure in this embodiment is a structure in which a wiring member 100 is wired to an electric junction box 1 such as a junction block. The electric junction box 1 has two terminal portions 2 and 3. The wiring member 100 has a bus bar 10 and an electric wire 60 as wiring materials, and ends of the bus bar 10 and the electric wire 60 are fastened and connected to the terminal portions 2 and 3 of the electric junction box 1. In this way, the wiring member 100 is wired to the electric junction box 1. The bus bar 10 and the electric wire 60 of the wiring member 100 are wiring materials that are connected from the electric junction box 1 to a battery or the like, with one being a positive electrode and the other being a negative electrode.

Figure 2 is a perspective view of the wiring member. Figure 3 is a perspective view of the wiring member with the ferrite case removed.

As shown in Figures 2 and 3, the wiring member 100 including the busbar 10 and the electric wire 60 has a ferrite portion 70. The ferrite portion 70 is provided with a ferrite 71, which is covered by a ferrite case 72 made of insulating resin. The ferrite 71 is composed of a pair of split ferrites 71a, 71b, which are combined with each other to form an elliptical ring shape.

The busbar 10 and the electric wire 60 are passed through the ring-shaped ferrite 71, and the outer circumference is covered by the ferrite 71 in the circumferential direction. As a result, even when a high voltage and large current flows through the busbar 10 and the electric wire 60, the ferrite 71 suppresses the generation of noise. In the ferrite 71, the busbar 10 and the electric wire 60 are arranged in parallel close to each other to form parallel wiring sections 10A, 60A.

The electric wire 60 arranged in parallel with the busbar 10 is an insulated electric wire in which the outer periphery of the core wire is covered with an outer sheath made of insulating resin, and a terminal fitting 61 having a hole 61a is connected to one end of the electric wire 60. The terminal fitting 61 provided at one end of the electric wire 60 is connected to the terminal portion 3 of the electrical connection box, and the other end is connected to, for example, a terminal of a battery.

FIG. 4 is a perspective view of a bus bar that constitutes the wiring member.
As shown in Fig. 4, the bus bar 10 is formed in a plate shape. The bus bar 10 is formed from a plate material made of a conductive metal material such as copper, a copper alloy, aluminum, or an 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 an electric wire connection portion 22 having a hole 22a. The terminal connection portion 21 of the bus bar 10 is connected to the terminal portion 2 of the electrical junction box 1, and an electric wire 23 is connected to the electric wire connection portion 22.

The other end of the busbar 10, which has the electric wire connection portion 22, is the parallel wiring portion 10A. In this parallel wiring portion 10A, the busbar 10 is passed through the ferrite 71 so that its width direction is aligned with the arrangement direction of the busbar 10 and the electric wires 60.

The busbar 10 has a horizontal bend 10B that is bent at a right angle in the horizontal direction at the end opposite the electric wire connection portion 22 in the parallel wiring portion 10A. The busbar 10 is bent at the horizontal bend 10B and has a horizontal extension portion 10C that extends laterally relative to the parallel wiring portion 10A. The end of the horizontal extension portion 10C opposite the parallel wiring portion 10A has a vertical bend 10D that is bent vertically. The terminal connection portion 21 side of the vertical bend 10D is a vertical extension portion 10E that extends to the opposite side of the electric wire connection portion 22. The end of the vertical extension portion 10E on the terminal connection portion 21 side has a vertical bend 10F that is bent vertically, and the opposite side of the vertical extension portion 10E in the vertical bend 10F is the terminal connection portion 21. In this way, the busbar 10 is bent at the horizontal bend 10B and the vertical bends 10D and 10F to change its extension direction.

Figure 5 is a perspective view of a bus bar connected to an electric wire and covered with a case. Figure 6 is a perspective view of a bus bar connected to an electric wire and covered with a case with the lid of the storage section open.

As shown in Figures 5 and 6, the busbar 10 is covered by a case 30 except for the terminal connection portion 21 and a part of the vertical extension portion 10E. The case 30 is composed of a first case 31 and a second case 32.

The first case 31 is attached to the lower side of the busbar 10, and the lower side of the busbar 10 is covered by the first case 31. The second case 32 is attached to the upper side of the busbar 10, and the upper side of the busbar 10 is covered by the second case 32. The second case 32 is assembled from the upper side to the first case 31 attached to the busbar 10. In this way, the first case 31 and the second case 32 are attached to the busbar 10, and the busbar 10 is covered by the case 30 consisting of the first case 31 and the second case 32.

The case 30, which is made up of the first case 31 and the second case 32, has multiple locking portions 37. The locking portions 37 are composed of locking claws 38 formed on the first case 31 and locking holes 39 formed on the second case 32. When the second case 32 is assembled to the first case 31 attached to the busbar 10, the locking claws 38 enter and lock into the locking holes 39. This locks the first case 31 and the second case 32 in the assembled state.

Fig. 7 is a perspective view of the storage unit with the lid open, and Fig. 8 is a vertical cross-sectional view of the storage unit along the wiring direction with the lid closed.
7 and 8 , the case 30 includes a housing portion 40 having a housing space S, and the housing space S of the housing portion 40 houses a connection portion between the electric wire connection portion 22 of the busbar 10 and the electric wire 23. The electric wire 23 is an insulated electric wire having a core wire covered with an outer sheath made of insulating resin, and is connected to, for example, a terminal of a battery. A terminal fitting 24 having a hole 24a is connected to an end of the electric wire 23, and the end to which the terminal fitting 24 is connected is housed in the housing space S of the housing portion 40.

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

The peripheral wall portion 42 is composed of two opposing side wall portions 44 and two opposing end wall portions 45 that are connected to the ends of the side wall portions 44. The peripheral wall portion 42 is provided to stand upright from the periphery of the bottom wall portion 41. One of the end wall portions 45 that constitutes the peripheral wall portion 42 is formed with a pull-out recess 45a, and the electric wire 23 is passed through this pull-out recess 45a.

The lid portion 43 is integrally molded with one of the side walls 44 constituting the peripheral wall portion 42 via a hinge portion 46. The lid portion 43 is rotatably connected to the side wall portion 44 by the hinge portion 46. The other side wall portion 44 constituting the peripheral wall portion 42 is formed with locking portions 44a, and these locking portions 44a can be locked into locking holes 43a formed in the edge portion of the lid portion 43 on the side opposite to the side on which the hinge portion 46 is formed.

A stud bolt 48 is erected on the bottom wall 41 that constitutes the accommodation section 40. The electric wire connection section 22 of the busbar 10 is accommodated in the accommodation space S with the stud bolt 48 inserted in its hole 22a. The terminal metal fitting 24 of the electric wire 23 with the stud bolt 48 inserted in its hole 24a is overlapped on the electric wire connection section 22. A nut (fastener) 49 is screwed onto the stud bolt 48 and tightened, thereby fastening the electric wire connection section 22 of the busbar 10 and the terminal metal fitting 24 of the electric wire 23.

The accommodation section 40, which accommodates the connection point between the busbar 10 and the electric wire 23, closes the accommodation space S by rotating the lid section 43 to cover the upper part of the peripheral wall section 42. At this time, the locking hole 43a of the lid section 43 is locked with the locking section 44a of the side wall section 44. This restricts the rotation of the lid section 43 and keeps the accommodation space S closed.

In addition, the lid portion 43 is formed with a recess 51 into which the tip of the stud bolt 48 is inserted when the storage space S is closed. The recess 51 has an engagement wall 52 formed on its periphery. When the storage space S is closed by the lid portion 43, the engagement wall 52 has a protruding dimension such that its end face is positioned at a position facing the nut 49 fastened to the stud bolt 48 with almost no gap. Therefore, if the nut 49 is not fastened sufficiently to the stud bolt 48, the nut 49 will rise, and the end face of the engagement wall 52 of the lid portion 43 will abut against the nut 49. For this reason, the lid portion 43 cannot completely close the storage space S, and the locking portion 44a of the side wall portion 44 will not be locked in the locking hole 43a of the lid portion 43. This makes it possible to detect a connection failure between the electric wire connection portion 22 of the busbar 10 and the terminal metal fitting 24 of the electric wire 23.

As described above, in the wiring structure according to this embodiment, the bus bar 10 and the electric wire 60 are passed through the annular ferrite 71, so that the ferrite 71 can suppress the generation of noise when a current flows through the bus bar 10 and the electric wire 60.

The busbar 10 is bent along the arrangement direction of the electric wires 60 between the terminal connection portion 21 connected to the electric connection box 1 and the parallel wiring portion 10A inserted into the ferrite 71. Therefore, the busbar 10 can be smoothly guided and wired from the connection point connected to the electric connection box 1 to the ferrite 71 adjacent to the electric wires 60. Therefore, multiple wiring materials consisting of the electric wires 60 and the busbar 10 can be easily wired to the electric connection box 1 by passing them through the annular ferrite 71.

The case 30 that covers the busbar 10 includes a housing portion 40 having a housing space S that houses the connection points between the busbar 10 and the terminal fittings 24, so that the connection points between the busbar 10 and the terminal fittings 24 can be housed and protected in the housing space S of the housing portion 40. By opening the lid portion 43, the connection points between the busbar 10 and the terminal fittings 24 in the housing space S can be visually inspected to check the presence or absence of nuts 49 and the connection state.

In addition, the lid portion 43 has an engagement wall 52 that is positioned without any gaps opposite the nut 49 when the storage space S is closed. Therefore, if the nut 49 is loose and raised, the engagement wall 52 hits the nut 49 and the lid portion 43 cannot be closed, which makes it possible to detect a poor connection between the bus bar 10 and the terminal fitting 24. In addition, because the lid portion 43 is rotatably attached to the peripheral wall portion 42, the number of parts can be reduced.

The parallel wiring portion 10A of the busbar 10 is passed through the ferrite 71 with its width direction aligned with the arrangement direction of the electric wires 60. Therefore, by wiring the wiring member 100 in the vehicle so that the arrangement direction of the busbar 10 and the electric wires 60 is horizontal, the bulkiness of the height can be suppressed, and the wiring can be easily performed in the narrow wiring space of a vehicle with height restrictions.

Next, modified examples of the storage section will be described.
(Variation 1)
Fig. 9 is a perspective view of the storage unit according to the modified example 1 with the lid open. Fig. 10 is a vertical cross-sectional view of the storage unit according to the modified example 1 along the wiring direction with the lid closed.
As shown in FIGS. 9 and 10, a storage section 40A according to the first modified example includes a peripheral wall section 42 and a lid section 43 that is separate from the peripheral wall section 42. As shown in FIG.

The peripheral wall portion 42 has one locking portion 44a on one side wall portion 44 and two locking portions 44a on the other side wall portion 44. The lid portion 43 has one locking hole 43a on one edge portion and two locking holes 43a on the other edge portion.

In the storage section 40A according to this modified example 1, the lid section 43 is placed over the upper part of the peripheral wall section 42, and the locking sections 44a of the peripheral wall section 42 are locked into the locking holes 43a of the lid section 43. As a result, the lid section 43 is assembled to the upper part of the peripheral wall section 42, and the storage space S is closed by the lid section 43.

In the case of this accommodation section 40A, if the nut 49 is not sufficiently tightened on the stud bolt 48 and the nut 49 is raised, the end face of the engagement wall 52 of the lid section 43 abuts against the nut 49. This makes it impossible to assemble the lid section 43 to the peripheral wall section 42, and this makes it possible to detect a poor connection between the electric wire connection section 22 of the busbar 10 and the terminal fitting 24 of the electric wire 23. In particular, in this accommodation section 40A, the end face of the engagement wall 52 of the lid section 43 abuts against the nut 49, causing the lid section 43 to come off the peripheral wall section 42, so that a poor connection between the electric wire connection section 22 of the busbar 10 and the terminal fitting 24 of the electric wire 23 can be detected more accurately.

(Variation 2)
Fig. 11 is a vertical cross-sectional view along the wiring direction of the storage unit according to the modified example 2. Fig. 12 is an exploded perspective view taken along the wiring direction of the storage unit according to the modified example 2. Fig. 13 is a vertical cross-sectional view along the wiring direction for explaining erroneous attachment in the storage unit according to the reference example. Fig. 14 is a vertical cross-sectional view along the wiring direction for explaining detection of erroneous attachment in the storage unit according to the modified example 2.

11 and 12, in the accommodation section 40B according to the second modification, the lid 43 is integrally formed with the second case 32, and a rib 55 is formed on the inside of the lid 43. The rib 55 is provided at a position facing the fastening point of the terminal metal fitting 24 by the stud bolt 28 and the nut 49, and is formed in a cylindrical shape having an inner diameter larger than that of the nut 49. The rib 55 is formed concentrically with the stud bolt 28 and protrudes toward the fastening point of the terminal metal fitting 24 by the stud bolt 28 and the nut 49. The rib 55 is disposed in a position surrounding the periphery of the nut 49 fastened to the stud bolt 48 when the second case 32 is assembled to the first case 31 and the lid 43 closes the accommodation space S. The rib 55 protrudes with a protruding dimension that allows a small gap to be left between the terminal metal fitting 24 fastened to the stud bolt 28 by the nut 49 when the lid 43 closes the accommodation space S. Therefore, when the lid 43 closes the storage space S, the rib 55 is not in contact with the stud bolt 28, the nut 49, or the terminal metal fitting 24.

However, when connecting the terminal fitting 24 to the electric wire connection portion 22 of the busbar 10, there is a risk of incorrect installation, that is, the terminal fitting 24 and the nut 49 are installed on the stud bolt 48 in the wrong order. Specifically, this occurs when the nut 49 is installed on the stud bolt 48, and then the stud bolt 48 is inserted into the hole 24a of the terminal fitting 24.

In such a case, as shown in FIG. 13, in the reference example storage unit 40R in which the lid portion 43 does not have a rib 55, even if an incorrect installation occurs, the second case 32 is assembled to the first case 31 and the lid portion 43 is placed over the storage unit 40R, so that the incorrect installation cannot be detected.

In contrast, as shown in FIG. 14, in the storage section 40B of Modification 2 in which the rib 55 is formed on the lid section 43, when an incorrect installation occurs and an attempt is made to assemble the second case 32 to the first case 31 and place the lid section 43 over the storage section 40B, the rib 55 of the lid section 43 abuts against the terminal fitting 24 located above the nut 49. As a result, the storage space S cannot be completely closed by the lid section 43 of the second case 32, and therefore incorrect installation of the terminal fitting 24 on the stud bolt 48 can be detected.

In the second modification, the cover 43 may also have an engagement wall 52 whose end face is positioned with almost no gap opposite the nut 49 when the storage space S is closed. In this case, it is possible to detect not only incorrect attachment of the terminal fitting 24 to the stud bolt 48, but also poor connection between the electric wire connection portion 22 and the terminal fitting 24 of the electric wire 23.

In addition, in the second modification, the lid portion 43 may be separate from the second case 32. In this manner, when the lid portion 43 is separate from the second case 32, the lid portion 43 may be rotatably connected to the peripheral wall portion 42 by the hinge portion 46, or may be separate from the peripheral wall portion 42.

In the above embodiment, the busbar 10 is passed through the ferrite 71 together with the electric wires 60 so that the width direction is aligned with the arrangement direction of the electric wires 60. However, as shown in FIG. 15, the busbar 10 may be passed through the ferrite 71 so that the width direction is perpendicular to the arrangement direction of the electric wires 60. In this case, when the busbar 10 is mounted on the vehicle so that the arrangement direction of the busbar 10 and the electric wires 60 is aligned horizontally, even when the vehicle is subjected to vertical vibrations, the displacement of the busbar 10 due to vibrations can be suppressed and the busbar 10 can be positioned in a stable state.

The present invention is not limited to the above-described embodiment, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, location, etc. of each component in the above-described embodiment are arbitrary as long as they can achieve the present invention, and are not limited.

Here, the features of the embodiments of the wiring structure according to the present invention described above will be briefly summarized and listed in the following [1] to [7].
[1] A wiring structure for a wiring member (100) connected to an electrical junction box (1),
The wiring member (100) is
An electric wire (60);
A plate-shaped bus bar (10) at least a portion of which is covered by a case (30);
an annular ferrite (71) through which the electric wire (60) and the bus bar (10) are inserted adjacent to each other;
Equipped with
The bus bar (10) is
A connection portion (terminal connection portion 21) to be connected to the electrical connection box (1);
A parallel wiring portion (10A) that is inserted into the ferrite (71);
having
A wiring structure in which the electric wires (60) are bent at at least one location between the connection portion (terminal connection portion 21) and the parallel wiring portion (10A) along the arrangement direction of the electric wires (60).

According to the wiring structure having the configuration [1] above, the bus bar and the electric wires are passed through the annular ferrite, so that the ferrite can suppress the generation of noise when a current flows through the bus bar and the electric wires.
In addition, the bus bar is bent at least at one location along the arrangement direction of the electric wires between the connection portion connected to the electric junction box and the parallel wiring portion inserted into the ferrite. Therefore, the bus bar can be smoothly led and wired from the connection portion connected to the electric junction box to the ferrite adjacent to the electric wires. Therefore, multiple wiring materials consisting of electric wires and bus bars can be easily wired to the electric junction box by passing them through the annular ferrite.

[2] The bus bar (10) has a terminal fitting (24) fastened to an end portion opposite to a connection portion (terminal connection portion 21) with the electric connection box (1) by a fastener (nut 49),
The case (30) includes an accommodation portion (40) having an accommodation space (S) for accommodating a connection portion between the bus bar (10) and the terminal fitting (24),
The storage section (40) is
A peripheral wall portion (42) surrounding the periphery of the storage space (S);
a lid portion (43) assembled to an upper portion of the peripheral wall portion (42) for opening and closing the storage space (S);
The wiring structure according to the above [1].

According to the wiring structure of the configuration [2] above, the connection points between the bus bar and the terminal fittings can be housed and protected in the accommodation space of the accommodation part. In addition, by opening the lid, the presence or absence of fasteners and the connection state can be confirmed by visually inspecting the connection points between the bus bar and the terminal fittings in the accommodation space.

[3] The wiring structure described in [2] above, in which the cover portion (43) has a rib (55) arranged in a position surrounding the fastener (nut 49) that fastens the terminal fitting (24) when the storage space (S) is closed.

According to the wiring structure of the configuration [3] above, when the lid closes the storage space, the rib is positioned to surround the fastener that fastens the terminal metal fitting. Therefore, if the fastener is fastened before the terminal metal fitting is attached and the terminal metal fitting is then attached, resulting in an incorrect installation state, the rib will hit the terminal metal fitting and the lid cannot be closed, which makes it possible to detect the incorrect installation of the terminal metal fitting.

[4] The cover portion (43) is provided rotatably with respect to the peripheral wall portion (42), and has an engagement wall (52) that is arranged without a gap at a position facing the fastener (nut 49) when the storage space (S) is closed.
The wiring structure according to the above [2] or [3].

According to the wiring structure of the configuration [4] above, when the lid is rotated to close the storage space, the engagement wall is positioned facing the fastener without any gaps. Therefore, if the fastener is loose and raised, the engagement wall hits the fastener and the lid cannot be closed, which makes it possible to detect a poor connection between the bus bar and the terminal fitting. In addition, because the lid is rotatably attached to the peripheral wall, the number of parts can be reduced.

[5] The cover portion (43) is detachable from the peripheral wall portion (42), and has an engagement wall (52) that is arranged without a gap at a position facing the fastener (nut 49) when the storage space (S) is closed.
The wiring structure according to the above [2] or [3].

According to the wiring structure of the configuration [5] above, when the lid is attached to the peripheral wall to close the storage space, the engagement wall is positioned facing the fastener without any gaps. Therefore, if the fastener loosens and rises up, the engagement wall hits the fastener and the lid comes off the peripheral wall, making it possible to detect a poor connection between the bus bar and the terminal fitting of the electric wire.

[6] The parallel wiring portion (10A) of the bus bar (10) has a width direction aligned with an arrangement direction of the electric wires (60).
The wiring structure according to the above [1] or [2].

According to the wiring structure of the configuration [6] above, by wiring the wiring components in the vehicle so that the arrangement direction of the bus bar and the electric wires is horizontal, it is possible to reduce the bulkiness of the height, and wiring can be easily performed in the narrow wiring space of a vehicle with height restrictions.

[7] The parallel wiring portion (10A) of the bus bar (10) has a width direction perpendicular to an arrangement direction of the electric wires (60).
The wiring structure according to the above [1] or [2].

According to the wiring structure of the configuration [7] above, by wiring the wiring members to the vehicle so that the arrangement direction of the bus bar and the electric wires is horizontal, even when the vehicle is subjected to vertical vibrations, the bus bar can be positioned in a stable state by suppressing displacement of the bus bar due to vibrations.
