[0009] Hereinafter, embodiments will be described with reference to the drawings. In the following description, components having the same or similar functions will be assigned the same reference numerals. Duplicate descriptions of those components may be omitted. Note that the configurations described below do not limit the scope of the embodiments.

[0010] In this disclosure, terms are defined as follows: "Connection" is not limited to mechanical connection and can include electrical connection. In other words, "connection" is not limited to direct connection between two elements to be connected, but can also include connection between two elements via another element interposed between them. "Containment" is not limited to entire components being contained, but can include only partial containment (with the remaining part of the component protruding). "Facing" means that virtual projections of two objects overlap when viewed from a specific direction. In other words, "facing" is not limited to two objects directly facing each other, but can include two objects facing each other with another component interposed between them. "Parallel," "orthogonal," and "same" can include "approximately parallel," "approximately perpendicular," and "approximately the same," respectively. "Sheet-like" or "sheet" is not limited to components with a thickness of 1 mm or more, but can also include components with a thickness of less than 1 mm (so-called films).

[0011] In the present disclosure, the +X direction, the −X direction, the +Y direction, the −Y direction, the +Z direction, and the −Z direction are defined as follows: The +X direction is the direction from the first end 80e1 to the second end 80e2 of the metal plate 80 (described later) (see FIG. 9 ). The −X direction is the direction opposite to the +X direction. Hereinafter, when there is no need to distinguish between the +X direction and the −X direction, they will simply be referred to as the “X direction.” The +Y direction and the −Y direction are directions that intersect (e.g., are perpendicular to) the X direction. The +Y direction is the direction from the third end 80e3 to the fourth end 80e4 of the metal plate 80 (described later) (see FIG. 9 ). The −Y direction is the direction opposite to the +Y direction. Hereinafter, when there is no need to distinguish between the +Y direction and the −Y direction, they will simply be referred to as the “Y direction.” The +Z direction and the −Z direction are directions that intersect (e.g., are perpendicular to) the X direction and the Y direction.

[0012] In the following, when there is no distinction between the X direction and the Y direction, they may be referred to as the "horizontal direction." In the following, the Z direction may be referred to as the "vertical direction." In addition, in the following, the +Z direction side may be referred to as "up" and the -Z direction side may be referred to as "down." However, these expressions are used for the convenience of explanation and do not limit the direction of gravity of the electrical connection unit 1 (the installation posture of the electrical connection unit 1).

[0013] (Embodiment) <1. Assembly structure> 1 is a cross-sectional view showing an assembly 100 of this embodiment. The assembly 100 includes an electrical connection unit 1 and a wiring member 300.

[0014] <2. Electrical connection unit configuration> The electrical connection unit 1 is an in-vehicle device mounted on a vehicle such as an EV (Electric Vehicle), an HEV (Hybrid Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle). The electrical connection unit 1 may be referred to as an "electrical connection box" or a "junction box," for example. However, the electrical connection unit 1 is not limited to a box-shaped device.

[0015] The electrical connection unit 1 is electrically connected to an external device. For example, the electrical connection unit 1 may be electrically connected to the external device via a wiring member 300. In the present disclosure, the term "external device" refers to an electrical device that exists outside the electrical connection unit 1. Examples of external devices include, but are not limited to, devices including an inverter for driving a vehicle motor, a charger for charging a battery pack, and the like.

[0016] The electrical connection unit 1 includes, for example, a main body MU, a metal plate 80, an insulating sheet 91 (see FIG. 9), a plurality of heat transfer members 92, and an insulating cover 93.

[0017] <3. Main body> First, the main body MU will be described. FIG. 2 is a perspective view illustrating the main body unit MU. The main body unit MU is a part that performs the main function of the electrical connection unit 1 (for example, switching the electrical connection state or overcurrent protection). In this embodiment, the main body unit MU is divided into multiple subunits SU. The main body unit MU is formed by connecting multiple subunits SU. In this embodiment, the main body unit MU has three subunits SU (subunits SUX, SUY, SUZ). Each subunit SU may be referred to as a "circuit assembly."

[0018] The subunit SUX has a first electrical function. The subunit SUX includes, for example, a plurality of electronic components 10X and a wiring board 40X. The plurality of electronic components 10X are electrically connected to the wiring board 40X.

[0019] The subunit SUY has a second electrical function. The second function is different from the first function. The subunit SUY includes, for example, a plurality of electronic components 10Y and a wiring board 40Y. The plurality of electronic components 10Y are electrically connected to the wiring board 40Y.

[0020] The subunit SUZ has a third electrical function. The third function is different from the first and second functions. The subunit SUZ includes, for example, a plurality of electronic components 10Z and a wiring board 40Z. The plurality of electronic components 10Z are electrically connected to the wiring board 40Z.

[0021] In this embodiment, the three subunits SUX, SUY, and SUZ are arranged side by side in the X direction.

[0022] Note that, instead of the above example, the main body MU does not have to be divided into multiple subunits SU. That is, the main body MU may be formed by multiple electronic components 10 and one wiring board 40. Furthermore, the two or more subunits SU are not limited to subunits SU having different functions, and may be subunits SU having the same function.

[0023] <4. Subunit Structure> Next, the configuration of the subunit SU will be described. 3 and 4, the subunit SU includes, for example, a plurality of electronic components 10, a plurality of connection components 20 for connecting the components, a wiring board 40, and a connector member 200. Each connection component 20 is a component that forms a vertical current path. The connection components 20 may also be referred to as "vertical wiring components."

[0024] <4.1 Electronic components and connecting parts> First, the electronic component 10 and the connecting component 20 for connecting the components will be described. The electronic component 10 is an electronic component mounted on the subunit SU according to the functions required of the subunit. The electronic component 10 is, for example, a connector, a fuse, a relay (e.g., a mechanical relay or a semiconductor relay), a capacitor, a branching component, various sensors (e.g., a current sensor or a voltage sensor), an electronic control unit, or an electronic component unit formed by unitizing two or more of these. The electronic component 10 is provided on the +Z direction side of the wiring board 40. Note that the type of electronic component 10 is not limited to the above example. The electronic component 10 is, for example, a heat-generating component that generates heat when powered on.

[0025] The connection component 20 is a component that electrically connects the electronic component 10 and the wiring board 40. The connection component 20 forms part of the current path in the subunit SU. The connection component 20 is provided on the +Z direction side of the wiring board 40. The connection component 20 is made of metal (for example, copper or a copper alloy). The connection component 20 may also be referred to as a "metal component."

[0026] <4.1.1 Electronic Components> 5, electronic component 10 is an electronic component in which multiple terminals 13 are arranged side by side at one component end 10e of electronic component 10. Electronic component 10 has, for example, case 11, component main body 12, multiple terminals 13, and multiple mounting portions 14.

[0027] (case) The case 11 is an outer shell member that forms most of the outer shape of the electronic component 10. The case 11 is made of, for example, synthetic resin and has insulating properties. The case 11 houses the component main body 12. The case 11 and the component main body 12 may be formed integrally. In this embodiment, the case 11 is formed, for example, in the shape of a rectangular parallelepiped.

[0028] In this embodiment, the case 11 has an insulating rib 11a that protrudes in a horizontal direction (e.g., the X direction) and extends in the Z direction. The insulating rib 11a is, for example, plate-shaped and extends along the horizontal direction (e.g., the X direction) and the Z direction. The insulating rib 11a extends, for example, over the entire length of the case 11 in the Z direction. The insulating rib 11a is disposed between a plurality of terminals 13 (terminals 13A and 13B, described later). The insulating rib 11a electrically insulates the terminals 13A and 13B. In this embodiment, a portion of the insulating rib 11a is disposed between first connection portions 21 (described later) of two connection parts 20 connected to the electronic component 10. The insulating rib 11a electrically insulates the first connection portions 21 of the two connection parts 20 connected to the electronic component 10.

[0029] 2, in this embodiment, at least one of the plurality of electronic components 10 includes a connector connection portion 17. The connector connection portion 17 may be provided on each of the plurality of electronic components 10. In this embodiment, the connector connection portion 17 is provided on, for example, an electronic component 10 that is a relay among the plurality of electronic components 10.

[0030] As shown in FIG. 6 , the connector connection portion 17 is electrically connected to the component main body portion 12 (described later) provided inside the case 11. A connector member 200 (described later) is detachably connected to the connector connection portion 17. The connector connection portion 17 is either a so-called female connector or a male connector. In this embodiment, the connector connection portion 17 is, for example, a male connector. The connector connection portion 17 is made of, for example, a synthetic resin and has insulating properties. The connector connection portion 17 holds a plurality of terminals (not shown) electrically connected to the internal circuit of the component main body portion 12.

[0031] The connector connection portion 17 is provided on a case side surface (component side surface) 11s of the case 11 facing one side in the Y direction. The connector connection portion 17 is provided on a case side surface 11s facing outward in the Y direction of the wiring board 40 in the Y direction. As shown in FIG. 2 , when the electrical connection unit 1 is viewed from the Z direction, the connector connection portion 17 of the electronic component 10A provided on the +Y direction side is provided to protrude in the +Y direction from the case side surface 11s facing in the +Y direction. When the electrical connection unit 1 is viewed from the Z direction, the connector connection portion 17 of the electronic component 10B provided on the -Y direction side is provided to protrude in the -Y direction from the case side surface 11s facing in the -Y direction. The connector connection portion 17 is configured to allow a first connector 201 of a connector member 200 (described later) to be inserted and removed along the X direction. By providing the connector connection portion 17 on the case side surface 11s facing outward in the Y direction of the wiring board 40, the connector member 200 can be easily attached to and detached from the connector connection portion 17 from outside the wiring board 40.

[0032] As shown in FIGS. 5 and 6 , the electronic component 10 has a connector cover 18 that covers the connector connection portion 17. The connector cover 18 is made of, for example, synthetic resin and has insulating properties. The connector cover 18 is formed integrally with the case 11. The connector cover 18 has a connector insertion hole 18h that is recessed on one side in the X direction. The connector insertion hole 18h opens on the other side in the X direction, and a first portion 205a of a connector member 200 (described below) can be inserted into the connector insertion hole 18h. In this embodiment, the connector cover 18 is provided on the end of the case side surface 11s that is away from the connection component 20 in the X direction. In this embodiment, the connector insertion hole 18h opens toward the connection component 20 in the X direction.

[0033] (Component body) The component body 12 is a part that performs the main function of the electronic component 10. For example, if the electronic component 10 is a relay, the component body 12 includes a switching part (e.g., a contact part) that switches between a conductive state and a non-conductive state. For example, if the electronic component 10 is a fuse, the component body 12 includes a fusing part that melts when an overcurrent flows. For example, if the electronic component 10 is a capacitor, the component body 12 includes a part that stores electric charge.

[0034] (Terminal) As shown in Fig. 5, terminal 13 is an electrical connection portion exposed to the outside of case 11. Terminal 13 is electrically connected to component body 12 inside case 11. In this embodiment, electronic component 10 includes terminal 13A and terminal 13B as the multiple terminals 13. One of terminal 13A and terminal 13B is a positive terminal. The other of terminal 13A and terminal 13B is a negative terminal.

[0035] In this embodiment, terminals 13A and 13B are provided at one component end 10e in the horizontal direction (e.g., X direction) of electronic component 10. Terminals 13A and 13B are arranged side by side in the horizontal direction (e.g., Y direction). Each terminal 13 has a mounting hole 13h to which a fastening member 71 (e.g., a screw or bolt) described later is attached. Mounting hole 13h opens in the horizontal direction (e.g., X direction). The inner circumferential surface of mounting hole 13h of electronic component 10 has a threaded groove.

[0036] (Mounting part) The mounting portion 14 is a portion for fixing the electronic component 10. The mounting portion 14 has a mounting hole 14h to which a fastening member 112 (e.g., a screw or a bolt, see FIG. 9 ), which will be described later, is attached. The mounting hole 14h is open in the Z direction. The mounting hole 14h is an insertion hole through which the fastening member 112 is passed. The destination to which the mounting portion 14 is fixed will be described later.

[0037] <4.1.2 Connecting parts> The connection component 20 is a component that electrically connects the electronic component 10 and the wiring board 40. In this embodiment, the connection component 20 electrically connects the electronic component 10 and a bus bar 42 (see FIG. 4 ) included in the wiring board 40. The connection component 20 has, for example, a first connection portion 21 and a second connection portion 22.

[0038] (First connection part) The first connection portion 21 of the connecting component 20 is a portion that is connected to the terminal 13 of the electronic component 10. The first connection portion 21 is a plate-like or rectangular column-like portion that extends in the Z direction. The first connection portion 21 extends in the Z direction along a component end 10e, which is one end portion of the electronic component 10 (for example, a plane that the component end 10e in the X direction has). The first connection portion 21 is an upright portion that stands in the Z direction relative to the wiring board 40 (for example, relative to a bus bar 42 described below). The first connection portion 21 is adjacent to the electronic component 10 in the horizontal direction (for example, the X direction). For example, the first connection portion 21 is adjacent to the terminal 13 of the electronic component 10 in the horizontal direction (for example, the X direction) and is connected to the terminal 13 of the electronic component 10 from the horizontal direction (for example, the X direction).

[0039] The first connection portion 21 of the connection component 20 has a first mounting hole 21h through which a fastening member 71 (e.g., a screw or a bolt) is passed. The first mounting hole 21h opens in the horizontal direction (e.g., the X direction). The fastening member 71 passed through the first mounting hole 21h engages with a mounting hole 13h in the terminal 13 of the electronic component 10, thereby physically and electrically connecting the first connection portion 21 to the terminal 13 of the electronic component 10.

[0040] (Second connection part) The second connection portion 22 of the connection component 20 is a portion that is connected to the bus bar 42 (see FIG. 9 ). The second connection portion 22 protrudes in the horizontal direction (e.g., the X direction) from the end 10f of the first connection portion 21 on the −Z direction side. The second connection portion 22 is a plate portion that extends horizontally and along the wiring board 40. The second connection portion 22 is adjacent to the bus bar 42 in the Z direction and is connected to the bus bar 42 from the +Z direction. The second connection portion 22 of the connection component 20 is attached from the +Z direction to a fastening member 43 (e.g., a screw or bolt, see FIG. 3 ) that protrudes from the bus bar 42 in the +Z direction, thereby being physically and electrically connected to the bus bar 42. In this embodiment, the second connection portion 22 of the connection component 20 has a second mounting hole 22h through which the fastening member 43 is passed. The second mounting hole 22h is open in the Z direction. The fastening member 43 of the second connection portion 22 is passed through the second mounting hole 22h. An engaging member 44 (e.g., a nut, see FIG. 3) engages with the tip of the fastening member 43 passed through the second mounting hole 22h, thereby fixing the second connecting portion 22 to the bus bar 42. In this embodiment, the first connecting portion 21 and the second connecting portion 22 form a single connecting part 20 that is L-shaped in side view from the Y direction.

[0041] The connection parts 20 are heat storage members (heat absorption members) that increase the heat capacity of the current paths of the electrical connection unit 1. The connection parts 20 store (absorb) at least a portion of the heat generated by the electronic components 10, for example. Alternatively / in addition to this, the connection parts 20 may store (absorb) at least a portion of the heat generated by the bus bars 42 when current is applied. The connection parts 20 may also be referred to as "heat storage parts" or "heat absorption parts."

[0042] <4.2 Wiring board> Next, the wiring board 40 will be described. FIG. 7 is a perspective view showing a wiring board 40. The wiring board 40 is a member that forms at least a portion of the electrical paths between multiple electronic components 10 and / or at least a portion of the electrical paths between the electronic components 10 and an external device. In this disclosure, the term "wiring board" refers to a board-type wiring structure. "Board-type" refers to a plate-like structure that is flat and extends along a single plane when viewed as a whole, regardless of its detailed shape. In this disclosure, "plate-like" does not necessarily mean a completely flat structure, but may also include a structure that has fixing structures or ribs protruding in the Z direction. In this embodiment, the wiring board 40 is plate-like and extends along the X and Y directions.

[0043] The wiring board 40 includes, for example, a base plate 41, one or more (e.g., a plurality of) bus bars 42, and a plurality of fastening members 43. In this embodiment, the base plate 41 and the plurality of bus bars 42 are integrated by insert molding. For example, the wiring board 40 is formed as a single member by insert molding the bus bars 42 with the base plate 41 after the fastening members 43 are fixed to the bus bars 42. In other words, the bus bars 42 are integrated with the base plate 41 without using fastening members such as screws or bolts. Note that the wiring board 40 may be formed using another structure instead of insert molding.

[0044] (base plate) The base plate 41 is a holding member that integrally holds together a plurality of bus bars 42 that are arranged horizontally at intervals from one another. The base plate 41 is made of, for example, synthetic resin and has insulating properties. The base plate 41 electrically insulates the plurality of bus bars 42 from one another. The base plate 41 is an example of a "base member." The base plate 41 may also be referred to as an "insulating substrate." The base plate 41 has, for example, a flat portion 51 and a plurality of fixing portions 52.

[0045] The flat surface portion 51 is a plate-shaped portion of the base plate 41. The flat surface portion 51 is a plate-shaped portion extending in the horizontal direction. The flat surface portion 51 forms the main portion of the base plate 41. The flat surface portion 51 forms the base portion (insulating base portion) of the base plate 41. In this embodiment, the flat surface portion 51 extends across the entire width of the base plate 41 in the X direction and across the entire width of the base plate 41 in the Y direction, excluding the four corner portions of the base plate 41.

[0046] The flat portion 51 has a first surface 51a and a second surface 51b. The first surface 51a is a surface facing the +Z direction. The first surface 51a is a flat surface extending along the horizontal direction. The first surface 51a faces the multiple electronic components 10 and also faces the insulating cover 93 (see FIG. 1) of the electrical connection unit 1. The second surface 51b is located on the opposite side to the first surface 51a. The second surface 51b is a surface facing the -Z direction. The second surface 51b is a flat surface extending along the horizontal direction. The second surface 51b faces the metal plate 80 (see FIG. 1). The thickness direction (plate thickness direction) of the flat portion 51 is the Z direction.

[0047] The flat portion 51 has, for example, one or more (e.g., a plurality of) accommodating portions 55 that each accommodate a bus bar 42. The plurality of accommodating portions 55 are formed spaced apart from one another in the X direction or the Y direction. Each accommodating portion 55 is, for example, a through-hole that penetrates the flat portion 51 in the Z direction. Note that instead of a through-hole, the accommodating portion 55 may be a recess that is provided on the first surface 51a or the second surface 51b of the flat portion 51 and recessed in the Z direction.

[0048] When viewed from the Z direction, each of the accommodating portions 55 has an outer shape corresponding to the shape of the bus bar 42 to be accommodated.

[0049] (busbar) Bus bar 42 is a routing member (electrical connection member) included in routing board 40. Bus bar 42 is, for example, a routing member for electrically connecting multiple electronic components 10. Alternatively, bus bar 42 may be a routing member for connecting electronic components 10 to an external device. Bus bar 42 is made of metal (for example, copper or a copper alloy) and is electrically conductive.

[0050] At least a portion of each busbar 42 has a plate shape extending in the horizontal direction. At least a portion of each busbar 42 is housed in the housing portion 55 and extends along the flat portion 51. That is, at least a portion of each busbar 42 extends along the first surface 51a of the flat portion 51. At least a portion of each busbar 42 extends horizontally within the housing portion 55. In this embodiment, each busbar 42 has a plate shape extending in the horizontal direction over the entire length of the busbar 42. Each busbar 42 is housed in the housing portion 55 over the entire length of the busbar 42 and extends along the flat portion 51. Hereinafter, the portion of each busbar 42 housed in the housing portion 55 and extending along the flat portion 51 may be referred to as a "plate portion 42p." The busbar 42 is a component that forms a horizontal current path. The busbar 42 may also be referred to as a "horizontal routing component." Of the multiple bus bars 42, some bus bars 42 may be, for example, bus bars included in a positive electrode line of the electrical connection unit 1. Of the multiple bus bars 42, some bus bars 42 other than the bus bars included in the positive electrode line may be, for example, bus bars included in a negative electrode line of the electrical connection unit 1.

[0051] 8 is a plan view showing the wiring board 40. The plate portion 42p of each bus bar 42 has, for example, a connection portion 61 and an extension portion 63.

[0052] The connection portion 61 is a portion that comes into contact with one connection component 20. The connection component 20 is a connection component that connects one electronic component 10 and the bus bar 42. The connection portion 61 is a portion of the bus bar 42 that overlaps with the connection component 20 when viewed from the Z direction. The connection portion 61 is adjacent to the connection component 20 in the Z direction and is connected to the connection component 20 from the Z direction. For example, when viewed from the Z direction, each connection portion 61 is located on the +X direction side or the −X direction side of the electronic component 10. Each connection portion 61 is electrically connected to the terminal 13A or the terminal 13B of the electronic component 10 via the connection component 20.

The routing member 300 is provided in an external device connected to the electrical connection unit 1, such as a device including an inverter for driving a vehicle motor, or a charger for charging a battery pack.

[0079] (Support) The support 310 integrally supports a plurality of relay connectors 320. The support 310 is, for example, a flat plate made of a flexible substrate or a solid substrate. The support 310 is disposed parallel to the insulating cover 93. As shown in FIG. 11 , the support 310 has a predetermined wiring pattern 312.

[0080] (Relay connector) 1 and 11, the relay connectors 320 are fixed to a surface 310f of the support body 310 facing the -Z direction.

[0081] The multiple relay connectors 320 are insertable into and removable from the second connectors 202 of the multiple connector members 200 in the +Z direction. That is, each relay connector 320 is detachably connected to the corresponding second connector 202. Each relay connector 320 is either a male connector or a female connector. In this embodiment, the relay connector 320 is, for example, a female connector. Each relay connector 320 is made of, for example, synthetic resin and has insulating properties. Each relay connector 320 holds multiple terminals (not shown) electrically connected to the wiring pattern 312 of the support body 310.

[0082] Each relay connector 320 is formed in a shape that allows it to be inserted into or removed from the second end 202j of the second connector 202. The multiple relay connectors 320 are provided so that they can be inserted into or removed from the second end 202j of the multiple connector members 200 in the Z direction. The second end 202j and the relay connector 320 are provided with engaging claws (not shown) or the like that can engage with each other when the second end 202j and the relay connector 320 are connected and each terminal of the second connector 202 and each terminal of the relay connector 320 are electrically connected.

[0083] <8. Manufacturing method of electrical connection unit> Next, a method for manufacturing the electrical connection unit 1 will be described. 12 to 17 are cross-sectional views illustrating a manufacturing method of the electrical connection unit 1. In the wiring board 40 of each subunit SU, the base plate 41 and the plurality of bus bars 42 are integrated by insert molding or another method, with the fastening members 43 fixed to the bus bars 42. With this integration, the wiring board 40 of each subunit SU is prepared in advance.

[0084] (1st step) 12 shows the first step. In the first step, the connecting part 20 is fixed to the terminal 13 of the electronic part 10 using the fastening member 71. This fixation forms an assembled part SA in which the electronic part 10 and the connecting part 20 are integrated together.

[0085] The first step is performed, for example, as follows: First, electronic component 10 is placed on mounting table MP with mounting holes 13h of terminals 13 of electronic component 10 facing vertically. Next, connection component 20 is placed on electronic component 10 with first mounting holes 21h of connection component 20 facing vertically. Then, first mounting holes 21h of connection component 20 are aligned with mounting holes 13h of terminals 13 of electronic component 10. The first step is performed with electronic component 10 and connection component 20 in a first position. In the first position, mounting holes 13h and first mounting holes 21h face vertically.

[0086] Next, fastening member 71 is inserted vertically into first mounting hole 21h of connecting part 20. Then, fastening member 71 that has passed through first mounting hole 21h of connecting part 20 engages with mounting hole 13h of terminal 13 of electronic component 10. This engagement forms assembled part SA in which electronic component 10 and connecting part 20 are integrated together.

[0087] (2nd process) 13 shows the second step. In the second step, the assembly component SA is fixed to the wiring board 40 of each subunit SU. For example, the connection component 20 included in the assembly component SA is fixed to the bus bar 42 included in the wiring board 40. This fixation electrically connects the electronic component 10 to the bus bar 42.

[0088] The second step is performed, for example, as follows. As described above, in the wiring board 40, the fastening members 43 are fixed to the busbars 42. The fastening members 43 protrude vertically from the busbars 42. Then, the assembly component SA is placed on the wiring board 40 by inserting the fastening members 43 vertically into the second mounting holes 22h of the second connection portions 22 of the connection components 20. Next, an engaging member 44 (e.g., a nut) is engaged with the upper end of the fastening members 43 from the vertical direction. This engagement fixes the second connection portions 22 of the connection components 20 included in the assembly component SA to the busbars 42. This fixation completes each subunit SU.

[0089] (3rd step) 14 shows the third step. In the third step, each subunit SU is attached to the metal plate 80. The third step is performed, for example, as follows. First, an insulating sheet 91 is attached to the surface of the flat portion 81 of the metal plate 80. Next, a heat transfer member 92 is fixed to the underside of each subunit SU using an adhesive or the like. Next, each subunit SU is placed on the metal plate 80 with the insulating sheet 91 and the heat transfer member 92 interposed therebetween. Then, the fixing portion 52 of each subunit SU is fixed to the fixing portion 82 of the metal plate 80 using fastening members 111.

[0090] (4th step) 15 shows the fourth step. In the fourth step, the mounting portion 14 of the electronic component 10 of each subunit SU is fixed to the fixing portion 83 of the metal plate 80 by the fastening member 112. In the fourth step, the connector member 200 is connected to the connector connecting portion 17 of the electronic component 10. Note that the fourth step may be performed together with the third step.

[0091] (5th step) 16 shows the fifth step. In this step, the insulating cover 93 is attached to the metal plate 80 in the vertical direction. This attachment completes the electrical connection unit 1. As shown in FIG. 1, with the insulating cover 93 attached to the metal plate 80, the second portions 205b of the connector members 200 protrude in the +Z direction from the insulating cover 93 through the connector insertion holes 93z.

[0092] (6th step) 17 shows the sixth step. In the sixth step, the routing member 300 is connected to the completed electrical connection unit 1. The routing member 300 collectively connects the multiple relay connectors 320 to the second connectors 202 of the multiple connector members 200 that protrude from the insulating cover 93 in the +Z direction.

[0093] <9. Advantages> In this embodiment, the routing member 300 includes a support 310 having a wiring pattern 312 and a plurality of relay connectors 320 fixed to the support 310. Each relay connector 320 is connected to an electronic component 10 via a connector member 200. The plurality of relay connectors 320 are provided so as to be insertable into and removable from the second ends 202j of the plurality of connector members 200 in the Z direction. With this configuration, the plurality of relay connectors 320 provided on the routing member 300 can be inserted into and removed from the second connectors 202 of the plurality of connector members 200 all at once. As a result, the ease of assembly when connecting the plurality of relay connectors 320 to the electronic component 10 can be improved.

[0094] In this embodiment, the second connector 202 to which the relay connector 320 is connected is provided on the second portion 205b extending in the +Z direction relative to the base member 41. With this configuration, when the relay connector 320 is inserted into or removed from the second connector 202, it is less likely to interfere with other electronic components 10, etc. As a result, the ease of assembly when connecting the relay connector 320 to the electronic component 10 can be improved.

[0095] In this embodiment, the second portion 205b of the connector holding portion 205 is inserted into the connector insertion hole 93z of the insulating cover 93. With this configuration, the second connector 202 held by the second portion 205b is exposed in the +Z direction from the connector insertion hole 93z. That is, when connecting to the electrical connection unit 1, the relay connector 320 can be inserted into or removed from the second connector 202 exposed from the insulating cover 93 from outside the insulating cover 93. As a result, assembly is easier when connecting the relay connector 320 to the electrical connection unit 1.

[0096] In this embodiment, the routing member 300 is provided on the +Z direction side of the insulating cover 93. With this configuration, the routing member 300 can be easily connected from outside the electrical connection unit 1.

[0097] In this embodiment, the connector member 200 is connected to the connector connection portion 17 with the first end portion 201j facing one side in the X direction. With this configuration, when the connector member 200 is inserted into or removed from the electronic component 10, the first end portion 201j of the first connector 201 provided on the connector member 200 is inserted into or removed from the connector connection portion 17 of the electronic component 10 in the X direction. In other words, the insertion / removal direction of the first connector 201 into or removed from the electronic component 10 is the X direction, while the insertion / removal direction of the relay connector 320 into or removed from the second connector 202 is the Z direction. As a result, when the relay connector 320 is inserted into or removed from the second connector 202, even if a force along the Z direction acts on the connector member 200, the first end portion 201j of the first connector 201 is prevented from coming off the connector connection portion 17 of the electronic component 10.

[0098] In this embodiment, the first connector 201 of the connector member 200 is insertable into and removable from the connector connection portion 17, which protrudes from the component side surface 11s of the electronic component 10 to one side in the Y direction, along the X direction. This configuration allows the first connector 201 to be easily connected to the electronic component 10.

[0099] In this embodiment, the electronic component 10 is provided with the connector cover 18. With this configuration, when the first connector 201 of the connector member 200 is inserted into or removed from the connector connecting portion 17 provided in the connector insertion hole 18h, the first connector 201 is guided by the connector insertion hole 18h. As a result, the ease of assembly when connecting the relay connector 320 to the electronic component 10 can be improved.

[0100] In this embodiment, at least a portion of the bus bar 42 is housed in the housing portion 55 of the flat portion 51 of the base member 41. With this configuration, the electrical connection unit 1 can be made low-profile.

[0101] <10. Variations> Next, several modified examples will be described. Note that the configuration of each modified example other than that described below is the same as that of the above-described embodiment.

[0102] In the above-described embodiment, the wiring member 300 is provided on the +Z direction side of the insulating cover 93, but the present invention is not limited to this. 18, the routing member 300 may be disposed between the insulating cover 93 and the plurality of electronic components 10. In other words, the routing member 300 may be housed inside the electrical connection unit 1. In this case, the second portion 205b (second connector 202) of each connector member 200 does not protrude from the insulating cover 93 in the +Z direction, but is disposed on the -Z direction side of the insulating cover 93.

[0103] In the above-described embodiment, the insulating cover 93 is provided, but the insulating cover 93 may be omitted by covering the electronic components 10 with the support 310 of the routing member 300.

[0104] In the above-described embodiment, the connector connection portion 17 is configured to be provided on the case side surface 11s facing outward in the Y direction of the wiring board 40, but the connector connection portion 17 may also be provided on the case side surface 11s facing in the X direction. Furthermore, in the above-described embodiment, the connector connection portion 17 is configured to insert and remove the first connector 201 of the connector member 200 in a direction along the case side surface 11s (X direction), but the connector connection portion 17 may also be configured to insert and remove the first connector 201 of the connector member 200 in a direction intersecting the case side surface 11s (Y direction).
