[0006] Patent Document 1: Japanese Patent Application Publication No. 2024-009566 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the electrical connection box and busbar described in Patent Document 1, in order to ensure space on the side of the electrical connection box and improve its mounting capacity, it is sometimes preferable to bend the portion of the busbar that connects to the terminals of the electrical connection box, i.e., the exposed conductor portion (connection portion). In such cases, the stepped portion formed in the busbar of Patent Document 1 cannot adequately ensure the aforementioned anti-finger-touch structure, therefore, it is necessary to study a structure that ensures safety.

[0009] This invention provides a conductive component and a mounting structure for the conductive component that can balance compatibility and safety.

[0010] Solution for solving the problem

[0011] This invention provides a conductive component comprising a flat conductive portion and an insulating protective cover covering the outer peripheral surface of the conductive portion. The conductive component connects two electrical components, wherein...

[0012] The conductive part has:

[0013] The main body, which is covered by the protective cover; and

[0014] The first and second connecting portions protrude from the protective cover and are electrically connected to the terminal portions of each electrical component.

[0015] The connecting portion of at least one of the first connecting portion and the second connecting portion is bent relative to the main body portion.

[0016] The protective cover is provided with an extension that extends from the position corresponding to the bend between the connecting portion and the main body portion.

[0017] Furthermore, the present invention provides a mounting structure for a conductive component, which comprises:

[0018] The aforementioned conductive components; and

[0019] A first electrical component and a second electrical component are respectively connected to the first connecting portion and the second connecting portion of the conductive component.

[0020] in,

[0021] The first electrical component and the second electrical component each have:

[0022] A terminal block having a terminal portion for connecting the first connection portion or the second connection portion to the conductive component; and

[0023] A terminal cover is disposed on the terminal block and covers the terminal portion connected to the first connecting portion or the second connecting portion.

[0024] A slit is provided between the terminal block and the terminal cover, allowing either the first connecting part or the second connecting part to pass through.

[0025] The extension of the protective cover has a plate shape that covers the slit when viewed from a first direction.

[0026] Invention Effects

[0027] According to the present invention, the connecting portion of the conductive part is bent relative to the main body, thus providing good mounting stability for the electrical component to which the conductive part is connected. Furthermore, in such a conductive component with a bent connecting portion, an extension is provided in the protective cover extending from the position corresponding to the bent portion between the connecting portion and the main body, thereby preventing the operator's hand or tools from contacting the connecting portion when the electrical component and the conductive part are connected.

[0054] Hereinafter, an embodiment of the conductive component and the mounting structure of the conductive component of the present invention will be described with reference to the accompanying drawings. The drawings are viewed from the orientation indicated by the reference numerals.

[0055] First, refer to Figure 1 and Figure 2 The conductive component 40 of one embodiment of the present invention will be described.

[0056] Figure 1 This is a three-dimensional view of the conductive component 40. Figure 2 This is a front view of the conductive component 40. Figure 1 and Figure 2 The description uses the arrows shown in the figure as the X-axis, Y-axis, and Z-axis directions, respectively.

[0057] The conductive component 40 includes a flat conductive portion 41 and an insulating protective cover 50 covering the outer peripheral surface of the conductive portion 41, and connects two electrical components. The two electrical components only need to have terminals for connecting to the conductive component 40; in one example described later, these are two battery modules 11. Here, the conductive component 40 is configured such that its length direction is the X-axis and its thickness direction is the Y-axis.

[0058] The conductive part 41 is a busbar formed of a conductive metallic material. The conductive part 41 is formed, for example, by stamping a metal sheet made of copper, iron, or aluminum. Alternatively, the conductive part 41 can also be formed by stamping a metal sheet made of an alloy such as a copper alloy or an aluminum alloy.

[0059] The conductive part 41 has a main body part 42 covered by a protective cover 50, and a first connection part 43a and a second connection part 43b that protrude from the protective cover 50 and are electrically connected to the terminal parts of each electrical component. In addition, the main body part 42 is not visible because it is covered by the protective cover 50, so it is shown as a dashed line in the illustration.

[0060] The first connecting portion 43a is provided at the end 42a on the +X side of the main body portion 42. The first connecting portion 43a is bent relative to the main body portion 42 towards the +Y side. Specifically, the first connecting portion 43a is bent at approximately a right angle from the edge portion 42e1 on the -Z side of the main body portion 42 towards the +Y side. Here, the bent portion between the first connecting portion 43a and the main body portion 42 is also referred to as the bent portion 44a. The bent portion 44a is provided on the -Z side relative to the main body portion 42.

[0061] The second connecting portion 43b is provided at the end 42b on the -X side of the main body portion 42. The second connecting portion 43b is bent relative to the main body portion 42 towards the +Y side. Specifically, the second connecting portion 43b is bent at approximately a right angle from the edge portion 42e2 on the +Z side of the main body portion 42 towards the +Y side. Here, the bent portion between the second connecting portion 43b and the main body portion 42 is also referred to as the bent portion 44b. The bent portion 44b is provided on the +Z side relative to the main body portion 42.

[0062] The surfaces of the first connecting part 43a and the second connecting part 43b both face the Z-axis direction and are provided with a through hole 45 extending along the Z-axis direction. The first connecting part 43a and the second connecting part 43b are connected to the electrical component, for example, by passing a double-headed bolt provided at the terminal of the electrical component through the through hole 45 and fastening it with a nut.

[0063] In this way, the first connecting portion 43a and the second connecting portion 43b of the conductive portion 41 are bent relative to the main body portion 42. Therefore, when the conductive member 40 is connected to the electrical component, the conductive member 40 does not protrude outward relative to the electrical component, making it easy to ensure space around the electrical component. As a result, the mounting capability of the electrical component can be improved.

[0064] The protective cover 50 is formed of an electrically insulating material such as synthetic resin. The protective cover 50 has a shape that follows the main body portion 42 of the conductive portion 41 and covers the main body portion 42.

[0065] The protective cover 50 has a first cover portion 51 that covers the main body portion 42 from the -Y side and a second cover portion 52 that covers the main body portion 42 from the +Y side. Recesses are formed on the surfaces of the first cover portion 51 and the second cover portion 52 opposite to the main body portion 42, and the main body portion 42 is disposed in the space S formed by the recesses (see reference). Figure 7 (a) and Figure 7 (b) A plurality of retaining portions 53 are provided at the periphery of the first cover portion 51 and the second cover portion 52, and the first cover portion 51 and the second cover portion 52 are fixed to each other by the retaining portions 53. The retaining portion 53 is, for example, composed of a claw portion and a hole portion that engages with the claw portion. In this way, the first cover portion 51 and the second cover portion 52 cover the main body portion 42 in such a way that they clamp the main body portion 42 in the thickness direction (Y-axis direction).

[0066] The protective cover 50 is provided with a first extension 55a and a second extension 55b extending from positions corresponding to the bends 44a and 44b of the conductive portion 41. The first extension 55a extends from the position corresponding to the bend 44a toward the -Z side in the Z-axis direction. The second extension 55b extends from the position corresponding to the bend 44b toward the +Z side in the Z-axis direction.

[0067] When viewed from the -Y side to the +Y side, the first extension 55a and the second extension 55b have plate shapes that cover the first connecting portion 43a and the second connecting portion 43b, respectively.

[0068] Because the protective cover 50 is provided with a first extension 55a and a second extension 55b, for example, when two electrical components are connected to the conductive component 40, it is possible to prevent the operator's fingers or tools from coming into contact with the first connection 43a and the second connection 43b, thus ensuring safety. Furthermore, as mentioned above, the conductive component 40 has a first connection 43a and a second connection 43b that are bent relative to the main body 42, therefore the electrical components connected to the conductive component 40 have good mounting properties, resulting in a balance between mounting performance and safety.

[0069] The conductive component 40 has an inclined portion 47 between the first connecting portion 43a and the second connecting portion 43b. The inclined portion 47 is disposed at the center of the conductive component 40 in the X-axis direction, extending along the -X side while inclined towards the -Z side.

[0070] The conductive member 40 has a shape symmetrical with respect to a central axis C1 passing through the center of the conductive portion 41. The central axis C1 is an axis extending along the thickness direction (Y-axis direction) of the conductive member 40. Specifically, in Figure 2 In this configuration, when the conductive component 40 is rotated 180° around the central axis C1, the rotated conductive component 40 is identical to the conductive component 40 before rotation. Therefore, when connecting the conductive component 40 to two electrical components, misassembly can be avoided, and the assemblability of the conductive component 40 can be improved.

[0071] Furthermore, a recess 48 is provided in the main body 42 of the conductive portion 41, formed by bending multiple parts. In one example shown in the figure, the recess 48 is configured to bend four parts of the main body 42 and recess them toward the +Y side. Because the recess 48 is provided, even when the relative positions of two electrical components connected by the conductive member 40 are misaligned, the tolerance can be absorbed by the elastic deformation of the conductive member 40 in the recess 48, thereby reducing the stress generated in the conductive portion 41.

[0072] Furthermore, at least in the recess 48, a gap is provided between the main body 42 and the protective cover 50. Specifically, the main body 42 is not tightly embedded in the space S within the protective cover 50; a gap is provided between it and the protective cover 50 so that deformation of the conductive part 41 can be tolerated to some extent within the space S. This prevents the protective cover 50 from being damaged due to deformation of the conductive part 41.

[0073] Next, the mounting structure of the conductive component according to one embodiment of the present invention will be described. Specifically, the mounting structure in which the aforementioned conductive component 40 is mounted on two electrical components will be described. Here, the case where the conductive component 40 is connected to two battery modules 11 will be described as an example. First, the battery pack 10 having two battery modules 11 will be described.

[0074] Figure 3 This is an exploded perspective view of a battery pack 10 mounted on a vehicle and equipped with a battery module 11. Figure 4 This is a side view of the battery pack 10 with two battery modules 11 connected by conductive components 40. Furthermore, the front of the vehicle equipped with the battery pack 10 is designated Fr, the rear is designated Rr, the left is designated L, the right is designated R, the top is designated U, and the bottom is designated D.

[0075] The battery pack 10 is used in electric vehicles such as hybrid vehicles and battery-powered electric vehicles. The battery pack 10 stores the electricity to be supplied to motors and other components that serve as the drive source for the vehicle.

[0076] The battery pack 10 is mounted on the vehicle floor 2. Specifically, the battery pack 10 is mounted, for example, on a recess 7 formed in the floor 2 and recessed downwards, with a cushioning material between it and the floor. A seat 3 (front or rear seat) is disposed above the battery pack 10, that is, the battery pack 10 is positioned below the seat 3. The seat 3 is mounted on a seat rail (not shown), which is suspended from a pair of front and rear crossbeams 5 and 6 of the vehicle body positioned in front of and behind the battery pack 10.

[0077] The battery pack 10 includes two battery modules 11 arranged in a front-to-back direction, an ECU (Electronic Control Unit) 12 for controlling the charging and discharging of the battery modules 11, a terminal block 13 with wiring components for the flow of charging and discharging current of the battery modules 11, a cooling mechanism 14 for cooling the battery modules 11 by means of cooling air drawn from the vehicle compartment, and a battery housing 15 for housing the above components.

[0078] The battery housing 15 includes: a housing body 16, which is a bottomed container with an opening at the top; and a housing cover 17, which covers the housing body 16 from above. The housing body 16 houses a battery module 11, an ECU 12, a terminal block 13, and a cooling mechanism 14. The front and rear ends of the housing cover 17 are fixed to a pair of front and rear crossbeams 5 and 6, thereby covering the housing body 16 mounted on the floor 2 from above. The housing cover 17 is configured to slope rearward and downward.

[0079] Two battery modules 11 are located on the left side of the housing body 16. Each battery module 11 is composed of multiple stacked individual cells, forming a cuboid shape with the left-right direction as its length. Each individual cell is, for example, a secondary battery such as a lithium-ion battery or a nickel-metal hydride battery.

[0080] Two battery modules 11 are fixed to the housing body 16 by module brackets 18 provided on the left and right sides. The two battery modules 11 have terminal portions 33 at the left end and are electrically connected to each other by connecting conductive parts 40 to each terminal portion 33.

[0081] The ECU 12 is mounted above the battery module 11 via the ECU bracket 19. The terminal block 13 is located on the right side and front side of the housing body 16.

[0082] The cooling mechanism 14 includes a fan 20 that draws in air from the vehicle compartment and blows air onto the battery module 11, an air intake duct 21 connected to the intake port of the fan 20, and an air outlet duct 22 connected to the air outlet of the fan 20. The cooling mechanism 14 is an air-cooled cooling device that cools the battery module 11 by means of air.

[0083] The intake duct 21 connects the intake grille 25, located at the right end of the housing 17, to the intake port of the fan 20. The air supply duct 22 guides the air blown by the fan 20 to the battery module 11. The fan 20, intake duct 21, and air supply duct 22 are configured in the housing body 16 to the right of the battery module 11.

[0084] Figure 5 This is a perspective view of the conductive component 40 connecting the two battery modules 11. Figure 6 This is a top view of the conductive component 40 that connects the two battery modules 11. Figure 7 (a) is Figure 6 AA line section view, Figure 7 (b) is a sectional view along the BB line.

[0085] Each battery module 11 includes: a terminal block 31 having a terminal portion 33 connected to a first connection portion 43a or a second connection portion 43b of a conductive member 40; and a terminal cover 35 disposed on the terminal block 31 and covering the terminal portion 33 connected to the first connection portion 43a or the second connection portion 43b. Additionally, Figure 5 In the text, the terminal cover 35 is omitted.

[0086] A double-ended bolt extending upwards is provided at the terminal portion 33. The double-ended bolt passes through a through hole 45 formed in the first connection portion 43a or the second connection portion 43b of the conductive member 40 and is fastened by a nut (not shown). In one illustrated example, the first connection portion 43a of the conductive member 40 is connected to the terminal portion 33 (e.g., the positive terminal) of the front battery module 11, and the second connection portion 43b of the conductive member 40 is connected to the terminal portion 33 (e.g., the negative terminal) of the rear battery module 11.

[0087] The first connecting portion 43a is bent relative to the main body portion 42 such that the main body portion 42 is positioned above the first connecting portion 43a. The second connecting portion 43b is bent relative to the main body portion 42 such that the main body portion 42 is positioned below the second connecting portion 43b.

[0088] The terminal cover 35 is formed of an electrically insulating material such as synthetic resin. The terminal cover 35 has a rotating shaft 36 extending in the left-right direction. The rotating shaft 36 is disposed at one end of the terminal cover 35 in the front-rear direction. The terminal cover 35 is axially supported by the rotating shaft 36 on a bearing 32 (see reference) disposed at the upper end of the terminal block 31. Figure 5 The terminal cover 35 is installed on the terminal block 31 in a way that allows it to rotate freely. When the conductive component 40 is connected to the terminal portion 33, the terminal cover 35 opens the top of the terminal block 31. After the conductive component 40 is connected to the terminal portion 33, it rotates to cover the top of the terminal block 31.

[0089] A slit 37 is provided between the terminal block 31 and the terminal cover 35, through which the first connecting portion 43a and the second connecting portion 43b of the conductive component 40 can pass. The main body portion 42 of the conductive component 40 is disposed on the outside of the terminal block 31, and the first connecting portion 43a and the second connecting portion 43b pass through the slit 37 and are connected to the terminal portion 33 of the terminal block 31.

[0090] The first connecting portion 43a is bent relative to the main body 42 such that the main body 42 is positioned above the first connecting portion 43a, so the upper part of the slit 37 of the front battery module 11 is covered by the portion of the protective cover 50 that covers the main body 42. Furthermore, the second connecting portion 43b is bent relative to the main body 42 such that the main body 42 is positioned below the second connecting portion 43b, so the lower part of the slit 37 of the rear battery module 11 is covered by the portion of the protective cover 50 that covers the main body 42. Therefore, it is possible to prevent the operator's fingers and tools from contacting the first connecting portion 43a and the second connecting portion 43b.

[0091] The lower part of the slit 37 of the front battery module 11 and the upper part of the slit 37 of the rear battery module 11 are covered by the first extension 55a and the second extension 55b of the protective cover 50.

[0092] The first extension 55a and the second extension 55b of the protective cover 50 have plate shapes that cover the first connecting portion 43a and the second connecting portion 43b, respectively, and cover the slit 37 when viewed from left to right when the conductive component 40 is installed on the terminal portion 33 of the battery module 11.

[0093] More specifically, the first extension 55a extends downward from the position corresponding to the bend 44a between the first connecting portion 43a and the main body portion 42, covering the lower part of the slit 37 of the front battery module 11. The second extension 55b extends upward from the position corresponding to the bend 44b between the second connecting portion 43b and the main body portion 42, covering the upper part of the slit 37 of the rear battery module 11.

[0094] In this way, the first extension 55a and the second extension 55b of the protective cover 50 cover the slit 37, thereby preventing the operator's fingers and tools from coming into contact with the first connection 43a and the second connection 43b, and ensuring safety.

[0095] Furthermore, the conductive component 40 has a first connecting portion 43a and a second connecting portion 43b that are bent relative to the main body 42. Therefore, the left side of the battery module 11 to which the conductive component 40 is connected does not protrude outward, ensuring sufficient space on the side of the battery module 11. As a result, the battery module 11 has good mounting relative to the housing body 16, thus achieving a balance between mounting performance and safety.

[0096] The conductive component 40 has a shape symmetrical with respect to the central axis C1 passing through the center of the conductive portion 41. Therefore, unlike the illustration, it is also possible to connect the second connection portion 43b of the conductive component 40 to the battery module 11 on the front side and the first connection portion 43a of the conductive component 40 to the battery module 11 on the rear side. In this way, misassembly of the conductive component 40 can be avoided, and the assemblability of the conductive component 40 can be improved.

[0097] Furthermore, the conductive member 40 has an inclined portion 47 between the first connecting portion 43a and the second connecting portion 43b. Therefore, the space above the conductive member 40 can be expanded by the inclined portion 47. In the battery pack 10 of this embodiment, as... Figure 4 As shown, the housing cover 17 is tilted and lowered to the rear, but the conductive component 40 has an inclined portion 47, so interference between the housing cover 17 and the conductive component 40 can be avoided.

[0098] Furthermore, the recess 48 of the main body 42 of the conductive part 41 is formed by recessing into the space between the battery modules 11 arranged in a front-to-back configuration. As a result, the space between the two battery modules 11 can be effectively utilized.

[0099] (Variation example)

[0100] Figure 8 This is a perspective view of the conductive component 40A in a modified example. In the following description, structures common to the conductive component 40 of the above embodiment are sometimes referred to by the same reference numerals.

[0101] The conductive component 40A has a flat conductive part 41 and an insulating protective cover 50 covering the outer peripheral surface of the conductive part 41, and connects two electrical components.

[0102] The basic structure of the conductive portion 41 of the conductive component 40A is the same as that of the conductive portion 41 of the conductive component 40, but the structures of the first connecting portion 43a and the second connecting portion 43b are different. Specifically, the first connecting portion 43a and the second connecting portion 43b of the conductive component 40A are both bent at approximately a right angle from the edge portion 42e1 on the -Z side of the main body portion 42 toward the +Y side.

[0103] The basic structure of the protective cover 50 of the conductive component 40A is the same as that of the protective cover 50 of the conductive component 40, but the structures of the first extension 55a and the second extension 55b are different. Specifically, the first extension 55a and the second extension 55b of the conductive component 40A both extend from the position corresponding to the bent portions 44a and 44b toward the -Z side in the Z-axis direction.

[0104] With this structure, for example, even when two electrical components are connected to the conductive component 40A, it is still possible to prevent the operator's fingers or tools from coming into contact with the first connection portion 43a and the second connection portion 43b, thus ensuring safety. Furthermore, as mentioned above, the conductive component 40A has a first connection portion 43a and a second connection portion 43b that are bent relative to the main body portion 42, therefore the electrical components connected to the conductive component 40A have good mounting properties, resulting in a balance between mounting performance and safety.

[0105] The present invention has been described above with reference to the accompanying drawings, including one embodiment and its variations. However, the present invention is not limited to this embodiment. Those skilled in the art will understand that various modifications or alterations can be conceived within the scope of the technical solutions described, and these modifications or alterations also fall within the technical scope of the present invention. Furthermore, the constituent elements of the above embodiments can be combined arbitrarily without departing from the spirit of the invention.

[0106] For example, in the aforementioned embodiments and modifications, conductive components 40 and 40A connect the terminal portions 33 of two battery modules 11 within the battery pack 10. However, they are not limited to this and can also connect electrical components other than the battery modules 11. For example, conductive components 40 and 40A can also connect the battery module 11 to the terminal block 13. Furthermore, conductive components 40 and 40A are not limited to connecting electrical components included in the vehicle's battery pack 10, but can connect any two electrical components. Moreover, the two electrical components are not limited to being mounted on a vehicle.

[0107] Furthermore, in the aforementioned embodiments and modifications, both the first connecting portion 43a and the second connecting portion 43b are bent relative to the main body portion 42. However, it is also possible for only one connecting portion to be bent relative to the main body portion 42. In this case, the extension of the protective cover 50 only needs to be provided at a position corresponding to the bend between that connecting portion and the main body portion 42.

[0108] At least the following items are described in this specification. The elements shown in parentheses are examples of components corresponding to the above embodiments, but are not intended to limit the scope.

[0109] (1) A conductive component (conductive component 40, 40A) comprising a flat conductive portion (conductive portion 41) and an insulating protective cover (protective cover 50) covering the outer peripheral surface of the conductive portion, the conductive component connecting two electrical components (battery module 11), wherein,

[0110] The conductive part has:
