The second connection port 43 is provided adjacent to the other end 41b of the recess 41 in the width direction Y, and faces the other end of the busbar 50 accommodated in the recess 41.

[0019] 3 is a perspective view of the connection unit 10 and the second electronic unit 30 of the electronic component unit 1. As shown in FIG. 3, the second electronic unit 30 has a housing 32 for integrating and accommodating electrical components such as a mating connector 34, a DC / DC converter, a DC / AC inverter, a branching section, and a control unit (not shown).

The second electronic unit 30 is also called an electrical connection box, a junction box, or the like.

[0020] The housing 32 includes, for example, a case 32A, a cover 32B, and a connector housing 32C. The case 32A is formed of, for example, a metal material together with a protrusion 33 described later, and the cover 32B and the connector housing 32C are formed of a resin material. The cover 32B and the connector housing 32C are assembled to the case 32A in a stacked state in the height direction Z, and the connector housing 32C is assembled to the cover 32B in a lined-up state in the axial direction X. With this configuration, the housing 32 is formed as a hollow box as a whole by combining the case 32A, the cover 32B, and the connector housing 32C. In the housing 32, an internal space defined by the case 32A, the cover 32B, and the connector housing 32C functions as an accommodation space.

[0021] Specifically, the case 32A is formed in a bottomed cylindrical shape (tray shape) with one side in the height direction Z open, and the cover 32B is formed in a bottomed cylindrical shape (tray shape) with the other side in the height direction Z open, and the peripheral portion of the case 32A and the peripheral portion of the cover 32B are joined by snap fitting or the like. In addition, the cover 32B is provided with a cutout portion 32d across the front wall 32a and the top wall 32b on one side (the connection unit 10 side) in the axial direction X, and the connector housing 32C is assembled so as to close the cutout portion 32d. The connector housing 32C is formed, for example, in a substantially L-shaped cross section having a portion constituting the front wall 32a together with the cover 32B and a portion constituting the top wall 32b, and is open on the other side in the axial direction X and both sides in the width direction Y. With this configuration, an accommodation space portion surrounded by the case 32A, the cover 32B, and the connector housing 32C is formed inside the housing 32.

[0022] The mating connector 34 includes, for example, a terminal 31 and a connector housing 32C that accommodates the terminal 31. The terminal 31 is connected to a board (not shown) accommodated in the accommodation space of the housing 32. Here, the terminal 31 is configured as a male terminal fitting including a tab terminal portion 31c electrically connected to the connector 14 (see FIG. 4) of the connection unit 10 and a board connection portion electrically connected to the board. The terminal 31 is entirely made of conductive metal, and each portion is integrally formed by press-molding a single sheet metal punched into a shape corresponding to each portion. In this embodiment, the mating connector 34 is provided with a plurality of terminals 31 (here, three) aligned in the width direction Y.

[0023] The connector housing 32C holds the terminal 31 therein. The connector housing 32C is provided with a fitting portion 34a protruding from a portion constituting the front wall 32a to one side in the axial direction X (the connection unit 10 side). The fitting portion 34a is formed, for example, in a rectangular tubular shape that covers the periphery of the tab terminal portion 31c of the terminal 31, and is fitted into the opening 12a (see FIG. 4) on the connector 14 side. In this embodiment, the mating connector 34 is provided with three fitting portions 34a aligned in the width direction Y corresponding to the terminals 31. The fitting portions 34a protect the tab terminal portions 31c of the terminals 31, respectively. The connector housing 32C is provided with a connection port 35 that is adjacent to the fitting portion 34a in the width direction Y and can be connected to a communication cable such as a LAN cable.

[0024] 4 is a perspective view of the connection unit 10 and the second electronic unit 30 of the electronic component unit 1, seen from a different angle than that of FIG. 3. As shown in FIG. 4, the connection unit 10 has a first housing 12 for integrating and accommodating, for example, a connector 14 and terminals of multiple wiring materials W. The first housing 12 is formed of a resin material or the like together with a pocket portion 13, which will be described later. The first housing 12 is formed into a hollow box shape as a whole, and an internal space defined by an outer wall of the first housing 12 functions as an accommodating space. The connection unit 10 is also called a connector unit or the like.

[0025] The connector 14 includes, for example, a first connection terminal 11 and a first housing 12 serving as a connector housing for accommodating the first connection terminal 11. The first connection terminal 11 is connected to an end of the wiring material W. Here, the first connection terminal 11 is configured as a female terminal fitting including a connector terminal portion 11c serving as a fork terminal portion electrically connected to the tab terminal portion 31c of the above-mentioned mating connector 34, and an electric wire connection portion 11d (see FIG. 5) electrically connected to the conductor portion W1 exposed at the end of the wiring material W. In this embodiment, the connector 14 is provided with three first connection terminals 11 aligned in the width direction Y corresponding to the terminals 31 of the mating connector 34.

[0026] The first housing 12 holds the first connection terminal 11 and the terminal of the wiring material W therein. The front wall 12b on the other side (the second electronic unit 30 side) of the first housing 12 in the axial direction X is provided with an opening 12a into which the above-mentioned fitting portion 34a fits. The opening 12a is formed as a space having a size and shape that allows the fitting portion 34a to fit in accordance with the outer shape of the fitting portion 34a, and here, a cross-sectional shape perpendicular to the axial direction X is formed into a substantially rectangular shape. The opening 12a is provided in a state in which the connector terminal portion 11c of the first connection terminal 11 held in the first housing 12 is exposed in the axial direction X. In this embodiment, the connector 14 is provided with three openings 12a aligned in the width direction Y corresponding to the first connection terminals 11, and the connector terminal portion 11c is protected by the surrounding wall portion of the opening 12a.

[0027] In addition, pocket portions 13 are provided on the side walls 12c on both sides of the first housing 12 in the width direction Y. The pocket portions 13 are formed integrally with the first housing 12, and are inserted into the pocket portions 13, into which the protrusions 33 of the second electronic unit 30 are inserted. The pocket portions 13 and the protrusions 33 function as positioning portions for aligning the connector 14 with the mating connector 34. Here, the pocket portions 13 and the protrusions 33 are provided as a pair on both sides of the width direction Y so as to sandwich the connector 14 and the mating connector 34 therebetween. The pocket portions 13 and the protrusions 33 are provided with through holes 13a, 33a that penetrate in the height direction Z, respectively, and bolts (not shown) are fastened to the through holes 13a, 33a.

[0028] FIG. 5 is a side view of the first connection terminal 11 in the connection unit 10. As shown in FIG. 5, the first connection terminal 11 includes, for example, the connector terminal portion 11c and the electric wire connection portion 11d described above, the linking portion 11a, and the first protruding portion 11b. The first connection terminal 11 is entirely made of a conductive metal, and each portion is integrally formed by press-molding a single sheet metal punched into a shape corresponding to each portion. The first connection terminal 11 may include a contact part 11g for reducing contact resistance as a separate part in the connector terminal portion 11c. The first connection terminal 11 is arranged in the axial direction X from the other side (the second electronic unit 30 side) to one side, in that order, and is linked to each other.

[0029] The connector terminal portion 11c is a portion (fork terminal portion) electrically connected to the tab terminal portion 31c of the mating connector 34 described above. The electric wire connection portion 11d is a portion connected to the wiring material W and electrically connects an end of the wiring material W to the first connection terminal 11. The electric wire connection portion 11d is crimped to an end of the wiring material W. At the end of the wiring material W on the first connection terminal 11 side, the covering portion W2 is stripped off and the conductor portion W1 is exposed from the covering portion W2, and the electric wire connection portion 11d is crimped to the end of the exposed conductor portion W1.

[0030] The connecting portion 11a is a portion that is interposed between the connector terminal portion 11c and the electric wire connection portion 11d and connects the connector terminal portion 11c and the electric wire connection portion 11d. In the first connection terminal 11, the connector terminal portion 11c and the electric wire connection portion 11d are electrically connected via the connecting portion 11a, and the connector terminal portion 11c and the conductor portion W1 of the wiring material W are electrically connected and conducted via the electric wire connection portion 11d.

[0031] The first protrusion 11b is a portion that is inserted into the first connection port 42 (see FIG. 7) of the bracket 40 and is electrically connected to the bus bar 50. The first protrusion 11b protrudes from the coupling portion 11a to the other side in the height direction Z and penetrates the bottom wall 12d (see FIG. 4) of the first housing 12. In other words, the first protrusion 11b is provided in a state protruding from the bottom wall 12d of the first housing 12. The first connection terminal 11 is electrically connected between the first protrusion 11b, the connector terminal portion 11c, and the electric wire connection portion 11d via the coupling portion 11a.

[0032] Fig. 6 is a schematic cross-sectional view of the first electronic unit 20 of the electronic component unit 1. As shown in Fig. 6, the first electronic unit 20 has a second housing 22 for collectively accommodating therein, for example, a second connection terminal 21, a substrate 23, an electronic component 24, etc. The second housing 22 is formed as a whole in a hollow box shape, and an internal space defined by an outer wall of the second housing 22 functions as an accommodating space 25. The second housing 22 is formed of, for example, a resin material or the like.

[0033] The second connection terminal 21 includes, for example, a base portion 21a and a second protrusion portion 21b. The second connection terminal 21 is entirely formed of a conductive metal member. The base portion 21a is connected to the substrate 23 and electrically connects the substrate 23 to the second connection terminal 21. The base portion 21a extends along the axial direction X, and an end portion on the substrate 23 side is joined to the substrate 23 by soldering or the like.

[0034] The second protrusion 21b is a portion that is inserted into the second connection port 43 (see FIG. 7) of the bracket 40 and is electrically connected to the bus bar 50. The second protrusion 21b protrudes from the base portion 21a to the other side in the height direction Z and penetrates the bottom wall 22a of the second housing 22. In other words, the second protrusion 21b is provided in a state protruding from the bottom wall 22a of the second housing 22. In the second connection terminal 21, the second protrusion 21b and the substrate 23 are electrically connected and conductive via the base portion 21a.

[0035] Fig. 7 is a cross-sectional view of the first connection port 42 (second connection port 43) of the bracket 40 of the electronic component unit 1. As shown in Fig. 7, the first connection port 42 is a portion into which the first protrusion 11b of the connection unit 10 is inserted, and the second connection port 43 is a portion into which the second protrusion 21b of the first electronic unit 20 is inserted. In this embodiment, the first connection port 42 and the second connection port 43 are provided with a contact member 60 and a support member 70, respectively.

[0036] The contact member 60 is a member for biasing the first protrusion 11b or the second protrusion 21b toward the bus bar 50. The contact member 60 is formed in an arc shape (arch shape) curved in a convex state toward the bus bar 50 from the wall surface 42b, 43b of the first connection port 42 or the second connection port 43 on the opposite side to the bus bar 50 in the width direction Y. In this embodiment, the distance in the width direction Y between the bus bar 50 and the contact member 60 in the free state of the contact member 60 is set to be smaller than the thickness in the width direction Y of the first protrusion 11b or the second protrusion 21b.

[0037] In such a configuration, by inserting the first protrusion 11b or the second protrusion 21b between the contact member 60 and the bus bar 50, the first protrusion 11b or the second protrusion 21b is elastically sandwiched between the contact member 60 and the bus bar 50. This causes the first protrusion 11b or the second protrusion 21b to be pressed against the bus bar 50, improving the reliability of the electrical connection between the bus bar 50 and the first protrusion 11b or the second protrusion 21b.

[0038] The support member 70 is a member for supporting the contact member 60. The support member 70 is formed, for example, in an L-shaped cross section having a portion extending along the wall surfaces 42b, 43b of the first connection port 42 or the second connection port 43 on the side opposite to the bus bar 50 and a portion extending along the bottom surfaces 42a, 43a of the first connection port 42 or the second connection port 43. The support member 70 is formed, for example, from a conductive metal member similar to the contact member 60 and the bus bar 50. The contact member 60 is joined to the portion extending along the wall surfaces 42b, 43b of the support member 70 by welding, crimping, or the like.

[0039] Fig. 8 is a side view (partial cross-sectional view) explaining a method for mounting the connection unit 10, the first electronic unit 20, and the second electronic unit 30 of the electronic component unit 1. As shown in Fig. 8, in this embodiment, the first electronic unit 20 is attached to the bracket 40 from one side in the height direction Z, and the connection unit 10 is attached to the bracket 40 from one side in the axial direction X. The second electronic unit 30 is attached in advance to a predetermined position on the bracket 40 by a fastener such as a bolt.

[0040] Then, by inserting the second protrusion 21b into the second connection port 43, the first electronic unit 20 is electrically connected to the bus bar 50 and assembled to the bracket 40. Also, by inserting the first protrusion 11b into the first connection port 42, the connection unit 10 is electrically connected to the bus bar 50 and assembled to the bracket 40, and the connection unit 10 and the first electronic unit 20 are electrically connected via the bus bar 50. Also, at this time, by inserting the connector 14 into the mating connector 34, the connection unit 10 and the second electronic unit 30 are electrically connected, and the first electronic unit 20 and the second electronic unit 30 are electrically connected via the first connection terminal 11 and the bus bar 50.

[0041] Thus, according to this embodiment, the connection unit 10, the first electronic unit 20, and the second electronic unit 30 can be electrically connected to each other simply by assembling each of them to the bracket 40. In this case, for example, power supplied from the wiring material W side of the connection unit 10 can be distributed in parallel to the first electronic unit 20 side and the second electronic unit 30 side via the first protrusion 11b and the connector terminal portion 11c of the first connection terminal 11.

[0042] The electronic component unit 1 is not limited to this example. For example, the power supplied from the wiring material W side of the connection unit 10 may be converted by a DC / DC converter or a DC / AC inverter on the second electronic unit 30 side and distributed to the first electronic unit 20 side. In this case, for example, the second electronic unit 30 may be provided with a protruding portion that protrudes from the housing 32 and is inserted into a connection port other than the first connection port 42 and the second connection port 43 of the bracket 40 to be electrically connected to the bus bar 50. The second electronic unit 30 may be connected to the connection unit 10 via the bus bar 50 by a protruding portion protruding from the housing 32 as in the first electronic unit 20, instead of being connected to the connection unit 10 via the terminal 31 of the mating connector 34.

[0043] As described above, the electronic component unit 1 and the wire harness WH of this embodiment include a connection unit 10 having a first connection terminal 11 provided at an end of a conductive wiring material W and a first housing 12 that houses the first connection terminal 11, a first electronic unit 20 having a second connection terminal 21 connected to a substrate 23 and a second housing 22 that houses the substrate 23 and the second connection terminal 21, a bus bar 50 that electrically connects the first connection terminal 11 and the second connection terminal 21, a recess 41 in which the bus bar 50 is disposed, and a metal plate 42 formed at one end 41a of the recess 41. The first connection terminal 11 protrudes from the first housing 12 and has a first protrusion 11b that is inserted into the first connection port 42 to be electrically connected to the bus bar 50 and that is assembled to the bracket 40, and the second connection terminal 21 protrudes from the second housing 22 and has a second protrusion 21b that is inserted into the second connection port 43 to be electrically connected to the bus bar 50 and that is assembled to the bracket 40.

[0044] With this configuration, the electronic component unit 1 and the wire harness WH can be assembled to the bracket 40 on the vehicle side by inserting the first protrusion 11b of the first connection terminal 11 into the first connection port 42 and the second protrusion 21b of the second connection terminal 21 into the second connection port 43, and can also be electrically connected to each other via the bus bar 50. As a result, the electronic component unit 1 and the wire harness WH can further improve the workability of the connection work between the connection unit 10 and the first electronic unit 20.

[0045] Moreover, the electronic component unit 1 and the wire harness WH of this embodiment include a second electronic unit 30 that is assembled to the bracket 40 and has a mating connector 34 that is electrically and mechanically connected to the connector 14 provided on the connection unit 10, and the first connection terminal 11 has a connector terminal portion 11c that is formed integrally with the first protrusion 11b and is exposed from the first housing 12 and is connected to a terminal 31 of the mating connector 34. With this configuration, the electronic component unit 1 and the wire harness WH can electrically connect the connection unit 10 and the second electronic unit 30 by connecting the connector 14 to the mating connector 34, and can also electrically connect the first electronic unit 20 and the second electronic unit 30 via the first connection terminal 11 and the bus bar 50. As a result, the electronic component unit 1 and the wire harness WH can further improve the workability of the connection work of the connection unit 10, the first electronic unit 20, and the second electronic unit 30.

[0046] In the electronic component unit 1 and the wire harness WH of this embodiment, the first connection port 42 is opened along the axial direction X of the wiring material W in which the connector 14 and the mating connector 34 are inserted and removed, and the first protrusion 11b is inserted into the first connection port 42 as the connector 14 is inserted into the mating connector 34. With this configuration, the electronic component unit 1 and the wire harness WH can simultaneously connect the connector terminal portion 11c of the first connection terminal 11 to the terminal 31 of the mating connector 34 and connect the first protrusion 11b of the first connection terminal 11 to the bus bar 50 by, for example, inserting the connector 14 into the mating connector 34 along the axial direction X. As a result, the electronic component unit 1 and the wire harness WH can further improve the workability of the connection work of the connection unit 10, the first electronic unit 20, and the second electronic unit 30.

[0047] Furthermore, in the electronic component unit 1 and the wire harness WH of this embodiment, the first connection port 42 and the second connection port 43 are provided with a contact member 60 that biases the first protrusion 11b or the second protrusion 21b inserted into the first connection port 42 and the second connection port 43 toward the bus bar 50. With this configuration, in the electronic component unit 1 and the wire harness WH, the first protrusion 11b or the second protrusion 21b is inserted between the contact member 60 and the bus bar 50, and the biasing force (elastic force) of the contact member 60 presses the first protrusion 11b or the second protrusion 21b toward the bus bar 50, thereby improving the reliability of the electrical connection between the bus bar 50 and the first protrusion 11b or the second protrusion 21b.

[0048] [First Modification] Fig. 9 is a cross-sectional view of the first connection port 42 (second connection port 43) of the bracket 40 of the electronic component unit 1 according to the first modified example. The electronic component unit 1 shown in Fig. 9 has a similar configuration to the electronic component unit 1 of the above embodiment. Therefore, the electronic component unit 1 can obtain the same actions and effects as the above embodiment based on the similar configuration.

[0049] 9, this modification differs from the above embodiment in that two contact members 60 are provided at each of the first connection port 42 and the second connection port 43. In this modification, the first protrusion 11b or the second protrusion 21b is inserted between the two contact members 60, and is configured so that the first protrusion 11b or the second protrusion 21b is elastically held between the two contact members 60.

[0050] The two contact members 60 bias the first protrusion 11b or the second protrusion 21b toward the center in the width direction Y. One of the contact members 60 is fixed to the bus bar 50 by welding or the like and is electrically connected to the bus bar 50. The other of the contact members 60 is fixed to the support member 70 by welding or the like and is electrically connected to the support member 70. The contact members 60 are formed in a curved arc shape (arch shape) that protrudes from the support member 70 and the bus bar 50 toward the center in the width direction Y.

[0051] In this modified example, the distance in the width direction Y between the two contact members 60 in a free state is set to be smaller than the thickness of the first protrusion 11b or the second protrusion 21b in the width direction Y. With this configuration, the first protrusion 11b or the second protrusion 21b is inserted between the two contact members 60, whereby the first protrusion 11b or the second protrusion 21b is elastically sandwiched between the two contact members 60, thereby further improving the reliability of the electrical connection between the first protrusion 11b or the second protrusion 21b and the bus bar 50.

[0052] [Second modified example] Fig. 10 is a cross-sectional view of the first connection port 42 (second connection port 43) of the bracket 40 of the electronic component unit 1 according to the second modified example. The electronic component unit 1 shown in Fig. 10 has a similar configuration to the electronic component unit 1 of the above embodiment. Therefore, the electronic component unit 1 can obtain the same actions and effects as the above embodiment based on the similar configuration.

[0053] However, this modification differs from the above embodiment in that the bus bar 50 is integrally formed with the support member 70 as shown in Fig. 10. That is, in this modification, the bus bar 50 is formed in a U-shaped cross section having a portion extending along the side surface of the recess 41, a portion extending along the bottom surface of the recess 41 and the bottom surfaces 42a, 43a of the first connection port 42 or the second connection port 43, and a portion extending along the wall surfaces 42b, 43b of the first connection port 42 or the second connection port 43. The contact member 60 is fixed by welding or the like to the portion of the U-shaped bus bar 50 that opens to one side in the height direction Z and extends along the wall surfaces 42b, 43b.

[0054] In this manner, in this modification, the bus bar 50 and the support member 70 are integrally molded, which reduces the number of parts and reduces the effort and cost required to manufacture the electronic component unit 1. Note that in this modification, the above first modification, and the above embodiment, the contact member 60 is configured as a separate part from the support member 70 and the bus bar 50, but the contact member 60 may be integrally molded with the support member 70 and the bus bar 50, for example.

[0055] Although the embodiment and the modified examples of the present invention have been illustrated above, the above-mentioned embodiment and the modified examples are merely examples and are not intended to limit the scope of the invention. The above-mentioned embodiment and the modified examples can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the gist of the invention. In addition, the specifications of each configuration, shape, and the like (structure, type, direction, type, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
