[0080] like Figures 1 to 3 As shown, the terminal block 1 of this embodiment includes a housing 2, a bus bar 3, a bushing 4, a capacitor 5, and a nut 6. The terminal block 1 is mounted on a vehicle, such as a hybrid vehicle or a plug-in hybrid vehicle. The illustrated terminal block 1 connects the vehicle's power supply, devices, and loads. The vehicle's power supply is, for example, a rechargeable battery.

[0081] The device connected to the terminal block 1 is, for example, a PCU (Power Control Unit) 100, which is located between the power supply and the driving motor. The PCU 100 is a control unit that includes a control circuit, an inverter, and a converter. In this embodiment, the terminal block 1 is described as being connected to the PCU 100 as the mating device. The load connected to the terminal block 1 receives power from the power supply, such as an air conditioner. The power supply supplies DC power to the load via the terminal block 1.

[0082] like Figure 2 and Figure 3 As shown, the housing 2 includes a main body 20 and a nut holder 21. The main body 20 and nut holder 21 are formed, for example, from an insulating synthetic resin. The main body 20 is integrally molded with the bus bar 3 and the sleeve 4, thereby retaining the bus bar 3 and the sleeve 4. The nut holder 21 engages with the main body 20 and supports the nut 6 and capacitor 5.

[0083] Busbar 3 is a conductor made of a conductive metal such as copper. Busbar 3 interconnects the power supply, PCU 100, and load. In the terminal block 1 of this embodiment, busbar 3 includes two busbars: busbar 31 and busbar 32.

[0084] The bushing 4 is configured to allow a fastening member such as a bolt to be inserted therethrough. The bushing 4 is formed, for example, from a conductive metal. The illustrated bushing 4 is cylindrical. The terminal block 1 of this embodiment includes two bushings 41 and 42 as the bushings 4. As described later, the bushing 41 is fastened to the metal case 201 along with the ground terminal 53 of the capacitor 5.

[0085] like Figure 3As shown in FIG. 1 , the capacitor 5 includes a housing 50, connection terminals 51 and 52, and a ground terminal 53. The connection terminals 51 and 52 and the ground terminal 53 protrude from the housing 50. The connection terminal 51 is connected to one bus bar 31, and the connection terminal 52 is connected to the other bus bar 32. The ground terminal 53 is grounded to the metal housing 201.

[0086] Nut 6 is supported by nut holder 21. The illustrated nut 6 is a square nut in a plan view. The terminal block 1 of this embodiment includes two nuts 61 and 62 as nuts 6. Bus bar 31 and connection terminal 51 are fastened together to one terminal of PCU 100 using nuts 61 and bolts. Bus bar 32 and connection terminal 52 are fastened together to the other terminal of PCU 100 using nuts 62 and bolts.

[0087] like Figure 4 As shown, busbar 31 has a first terminal portion 31a, a second terminal portion 31b, a third terminal portion 31c, and a main body 31m. Main body 31m is plate-shaped and has a first base portion 31p, a second base portion 31q, and a bent portion 31n. Bend portion 31n is the intersection of first base portion 31p and second base portion 31q, and is bent at a right angle.

[0088] The first terminal portion 31a and the third terminal portion 31c are connected to the first base portion 31p. More specifically, the first terminal portion 31a is formed at the end of the first base portion 31p on the side opposite to the second base portion 31q. The third terminal portion 31c protrudes in a direction perpendicular to the first base portion 31p. The third terminal portion 31c is a male terminal formed by rolling a metal plate into a cylindrical shape. The second terminal portion 31b protrudes in a direction perpendicular to the second base portion 31q. The second terminal portion 31b is a male terminal formed by rolling a metal plate into a cylindrical shape.

[0089] The axial direction of the second terminal portion 31b is perpendicular to the axial direction of the third terminal portion 31c. In the description of the terminal block 1, the axial direction of the second terminal portion 31b is referred to as the "first direction X," and the axial direction of the third terminal portion 31c is referred to as the "second direction Y." Furthermore, the direction perpendicular to both the first direction X and the second direction Y is referred to as the "third direction Z." The first terminal portion 31a is perpendicular to the third direction Z. The main body 20 of the housing 2 is integrated with the main body 31m by insert molding.

[0090] The structure of bus bar 32 is similar to that of bus bar 31. Figure 5 As shown, busbar 32 has a first terminal portion 32a, a second terminal portion 32b, a third terminal portion 32c, and a main body 32m. Main body 32m is plate-shaped and has a first base portion 32p, a second base portion 32q, and a bent portion 32n. Bend portion 32n is the intersection of first base portion 32p and second base portion 32q, and is bent at a right angle.

[0091] The first terminal portion 32a and the third terminal portion 32c are connected to the first base portion 32p. The first terminal portion 32a is perpendicular to the third direction Z. The third terminal portion 32c protrudes relative to the first base portion 32p in the second direction Y. The second terminal portion 32b is connected to the second base portion 32q. The second terminal portion 32b protrudes relative to the second base portion 32q in the first direction X. The main body 20 of the housing 2 is integrated with the main body 32m by insert molding.

[0092] exist Figure 6 shows the positional relationship between bus bars 31 and 32 held in housing 2. Main body 32m of bus bar 32 is positioned outside main body 31m of bus bar 31. Furthermore, bus bar 32 is positioned so that first base 32p faces first base 31p of bus bar 31, and second base 32q faces second base 31q of bus bar 31. Main bodies 31m and 32m are curved to surround housing 25 of main body 20.

[0093] The two first terminals 31a and 32a are arranged along the first direction X. The first terminals 31a and 32a are provided with through holes 31d and 32d for inserting the bolts 7. The two second terminals 31b and 32b are arranged along the second direction Y. The two third terminals 31c and 32c are arranged along the third direction Z.

[0094] exist Figure 7 and Figure 8 The main body 20 of the housing 2 is shown in FIG. Figure 7 as well as Figure 8 The busbar 3 is not shown in the figure. The main body 20 includes a main portion 22, a first cylindrical portion 23, and a second cylindrical portion 24. The main portion 22 is the main part of the main body 20 and is formed in a block shape. The main portion 22 is roughly rectangular. The main portion 22 has two fixing portions 22a and 22b protruding laterally. One fixing portion 22a holds the sleeve 41, and the other fixing portion 22b holds the sleeve 42. The sleeves 41 and 42 penetrate the fixing portions 22a and 22b along the third direction Z.

[0095] The main portion 22 has two nut holes 22c and 22d. The nut holes 22c and 22d are provided at a first end portion 221 of the main portion 22. The first end portion 221 is one end portion of the main portion 22 in the third direction Z. One end of the nut holes 22c and 22d opens toward the third direction Z. The other end of the nut holes 22c and 22d communicates with the accommodating portion 25, described later. The cross-section of the nut holes 22c and 22d perpendicular to the third direction Z is rectangular. The nut holes 22c and 22d are formed to restrict the rotation of the nut 6.

[0096] The first cylindrical portion 23 protrudes from one side surface of the main portion 22 in the first direction X. The interior of the first cylindrical portion 23 is divided into two spaces 23b and 23c by a partition wall 23a. One space 23b accommodates the second terminal portion 31b of the bus bar 31, and the other space 23c accommodates the second terminal portion 32b of the bus bar 32. For example, a power supply-side connector fits into the first cylindrical portion 23.

[0097] The second cylindrical portion 24 protrudes from the other side surface of the main portion 22 in the second direction Y. The interior of the second cylindrical portion 24 is divided into two spaces 24b and 24c by a partition wall 24a. One space 24b accommodates the third terminal portion 31c of the bus bar 31, and the other space 24c accommodates the third terminal portion 32c of the bus bar 32. For example, a load-side connector is mated with the second cylindrical portion 24.

[0098] like Figure 8 As shown, the main portion 22 includes a housing portion 25. The housing portion 25 opens at the second end 222 of the main portion 22. The second end 222 is the end of the main portion 22 on the side opposite the first end 221. The housing portion 25 is recessed from the second end 222 toward the first end 221. The housing portion 25 has a generally rectangular cross-sectional shape perpendicular to the third direction Z. The main portion 22 includes a groove 22e surrounding the opening of the housing portion 25. A notch 22f corresponding to the ground terminal 53 of the capacitor 5 is formed in the wall of the groove 22e.

[0099] like Figure 9 As shown, the nut holder 21 includes a base 26, a first support portion 27, a second support portion 28, and a cover portion 29. The base 26 has a substantially rectangular parallelepiped shape. The first support portion 27 and the second support portion 28 protrude from the base 26 in the third direction Z. The first support portion 27 and the second support portion 28 are arranged along the first direction X. The first support portion 27 and the second support portion 28 are prismatic in shape. The first support portion 27 supports the nut 61 at its distal end surface. The second support portion 28 supports the nut 62 at its distal end surface. The distal ends of the first support portion 27 and the second support portion 28 have recesses 27a and 28a corresponding to the bolt 7.

[0100] An arm-shaped engaging portion 26a is disposed between the first support portion 27 and the second support portion 28. The engaging portion 26a protrudes from the base portion 26 in the third direction Z. A claw 26b is formed at the distal end of the engaging portion 26a, which is engaged by the main body 20. The nut holder 21 engages with the main body 20 via the engaging portion 26a.

[0101] The base 26 includes a third support portion 26 c that supports the frame 50 of the capacitor 5 . The third support portion 26 c protrudes from a side surface 26 d of the base 26 in the second direction Y. The third support portion 26 c includes a recess 26 e corresponding to the ground terminal 53 of the capacitor 5 .

[0102] Lid 29 closes the entrance to accommodating portion 25. Lid 29 is connected to end 26f of base 26. A peripheral wall 29a extends vertically from the edge of lid 29. Peripheral wall 29a is inserted into groove 22e of main body 20. A notch 29b corresponding to ground terminal 53 of capacitor 5 is formed in peripheral wall 29a.

[0103] exist Figure 10 The figure shows the positional relationship of the various components within the housing 25. The side surface 26d and third support portion 26c of the nut holder 21 support and position the frame 50 of the capacitor 5. The connecting terminals 51 and 52 have flat contact portions 51a and 52a. Through-holes 51b and 52b corresponding to the bolts 7 are formed in the contact portions 51a and 52a, respectively.

[0104] The contact portion 51a is located on the side opposite to the first support portion 27 relative to the nut 61. The through-hole 51b of the contact portion 51a is opposed to the threaded hole of the nut 61 in the third direction Z. The contact portion 52a is located on the side opposite to the second support portion 28 relative to the nut 62. The through-hole 52b of the contact portion 52a is opposed to the threaded hole of the nut 62 in the third direction Z.

[0105] Two capacitor bodies 54 and 55 are arranged inside the housing 50. The capacitor bodies 54 and 55 are, for example, capacitor elements. The connection terminal 51 is connected to the ground terminal 53 via the capacitor body 54. The connection terminal 52 is connected to the ground terminal 53 via the capacitor body 55.

[0106] The ground terminal 53 protrudes to the outside space through the notch 29b of the cover 29. The ground terminal 53 has an annular contact portion 53a. The contact portion 53a is located outside the cover 29. A through hole 53b corresponding to the fastening member 8 is formed in the contact portion 53a.

[0107] exist Figure 11 The cross-sectional view of FIG shows the positional relationship between the bus bar 32, the connecting terminal 52, the nut 62, and the second support portion 28. The first terminal portion 32a of the bus bar 32, the contact portion 52a of the connecting terminal 52, the nut 62, and the second support portion 28 are arranged in this order along the third direction Z. In other words, the contact portion 52a of the connecting terminal 52 is located between the nut 62 and the first terminal portion 32a.

[0108] The nut holder 21 supports the nut 62 via the second support portion 28, so that the nut 62 faces the first terminal portion 32a of the bus bar 32. The second support portion 28 positions the nut 62 within the nut hole 22d of the main body 20. The through-hole 32d of the bus bar 32, the through-hole 52b of the connecting terminal 52, and the threaded hole of the nut 62 are coaxially arranged. The nut holder 21 supports the capacitor 5 via the base 26, so that the contact portion 52a faces the first terminal portion 32a.

[0109] The positional relationship between the bus bar 31, the connecting terminal 51, the nut 61, and the first support portion 27 is the same as the positional relationship between the bus bar 32, the connecting terminal 52, the nut 62, and the second support portion 28. Specifically, the nut holder 21 supports the nut 61 via the first support portion 27, such that the nut 61 faces the first terminal portion 31a of the bus bar 31. Furthermore, the nut holder 21 supports the capacitor 5 via the base portion 26, such that the connecting terminal 51 faces the first terminal portion 31a.

[0110] like Figure 11 As shown, the cover 29 of the nut holder 21 seals the entrance 25a of the accommodating portion 25. The peripheral wall 29a of the cover 29 extends into the groove 22e of the main body 20, restricting the intrusion of foreign matter into the accommodating portion 25. In other words, the nut holder 21 is configured to enclose the interior of the accommodating portion 25 as a sealed space, thereby protecting the capacitor 5. Furthermore, the cover 29 receives chips generated when the bolt is tightened on the nut 6, preventing the chips from leaking out of the accommodating portion 25.

[0111] like Figure 12 As shown, the first terminal portion 32a of the bus bar 32 and the connecting terminal 52 are fastened together to the terminal 101 of the PCU 100 by means of a bolt 7 and a nut 62. The bolt 7 is inserted through the terminal 101, the first terminal portion 32a, and the connecting terminal 52 and then screwed into the nut 62. The recess 28a of the second support portion 28 receives the distal end of the bolt 7. Similarly, the first terminal portion 31a of the bus bar 31 and the connecting terminal 51 are fastened together to another terminal of the PCU 100 by means of a bolt and a nut 61.

[0112] Figure 13 FIG. 5 shows the ground terminal 53 in a state where the frame 50 of the capacitor 5 is accommodated in the accommodation portion 25. Figure 13 As shown, the housing 25 houses the frame 50 with the contact portion 53a of the ground terminal 53 facing the sleeve 41, and holds the frame 50. Thus, the ground terminal 53 and the sleeve 41 can be fastened together to the metal box by the fastening member.

[0113] The illustrated housing 2 is configured such that the through hole 53b of the ground terminal 53 is positioned coaxially with the through hole 41a of the sleeve 41 when the frame 50 is accommodated in the accommodating portion 25. At this time, the contact portion 53a is opposed to the sleeve 41 in the third direction Z. Figure 13 As shown, the housing 2 holds the frame 50 so that the contact portion 53a is located near the sleeve 41. The housing 2 may hold the frame 50 in a state where the contact portion 53a is in contact with the sleeve 41.

[0114] like Figure 14 As shown, the ground terminal 53 of the capacitor 5 is connected to a metal housing 201 mounted on the vehicle 200 and is grounded. More specifically, the ground terminal 53 and the bushing 41 are fastened together to the metal housing 201 via a fastening member 8. The metal housing 201 is, for example, a housing for a device controlled by the PCU 100. The metal housing 201 may also be a housing for an inverter. The metal housing 201 is electrically connected to the metal body panels of the vehicle 200 and to conductive components disposed within the vehicle 200, and is grounded.

[0115] The fastening component 8 is a component, such as a bolt, having a shaft portion 8a that can be inserted through the ground terminal 53 and the sleeve 41. The shaft portion 8a of the fastening component 8 is inserted through the sleeve 41 and, in turn, through the through-hole 53b of the ground terminal 53. The fastening component 8 fastens the ground terminal 53 and the sleeve 41 to the metal case 201 by threading the shaft portion 8a into the mating threaded portion 202. The mating threaded portion 202 is, for example, a threaded hole formed in the metal case 201. The mating threaded portion 202 can also be a threaded hole for a nut. In this case, the metal case 201 is provided with a through-hole. The fastening component 8 includes a bolt and a nut, and the bolt and nut fasten the ground terminal 53 and the sleeve 41 to the metal case 201.

[0116] The fastening member 8 may be a stud bolt and a nut erected on the metal box 201. In this case, the stud bolt is inserted through the ground terminal 53 and the bushing 41, and the nut is screwed to the stud bolt.

[0117] As described above, the terminal block 1 of this embodiment includes a bus bar 3, a bushing 41, a housing 2, and a capacitor 5. The bus bar 3 is a conductor connected to a device such as the PCU 100. The bushing 41 is a component through which the fastening member 8 is inserted. The housing 2 is integrally formed with the bus bar 3 and the bushing 41. The capacitor 5 includes a frame 50 and a ground terminal 53 protruding from the frame 50. The capacitor 5 is connected to the bus bar 3.

[0118] The housing 2 holds the frame 50 so that the ground terminal 53 faces the sleeve 41, allowing the ground terminal 53 and the sleeve 41 to be fastened together to the metal case 201 using the fastening member 8. The terminal block 1 of this embodiment simultaneously secures the housing 2 to the metal case 201 and grounds the ground terminal 53 relative to the metal case 201. Therefore, the terminal block 1 of this embodiment can be efficiently assembled to the metal case 201.

[0119] The busbar 3 of this embodiment has first terminal portions 31a and 32a. The first terminal portions 31a and 32a are fastened together to the terminal 101 of a device such as the PCU 100 by bolts 7 and nuts 6. The housing 2 has a main body 20 having a housing portion 25 for housing the frame 50, and a nut holder 21. The nut holder 21 is housed in the housing portion 25 together with the frame 50 of the capacitor 5 and engages with the main body 20. The nut holder 21 has a first support portion 27, a second support portion 28, and a cover portion 29. The first support portion 27 and the second support portion 28 support the nut 6 so that the nut 6 is opposite to the first terminal portions 31a and 32a. The cover portion 29 closes the entrance 25a of the housing portion 25. The nut holder 21 of this embodiment can arrange the nut 6 in an appropriate position and protect the frame 50 of the capacitor 5.

[0120] The capacitor 5 of this embodiment has connection terminals 51 and 52 protruding from the frame 50. The connection terminals 51 and 52 are interposed between the nut 6 and the first terminal portions 31a and 32a, and are fastened together with the first terminal portions 31a and 32a and the terminal 101 by the bolt 7 and nut 6. This structure allows the connection terminals 51 and 52, the first terminal portions 31a and 32a, and the terminal 101 to be fastened together, improving workability.

[0121] [Modification of the embodiment]

[0122] A modification of the embodiment will be described. The device to which the first terminal portions 31a and 32a of the bus bar 3 are connected is not limited to the PCU 100. The first terminal portions 31a and 32a may be connected to terminals of a device other than the PCU 100.

[0123] The capacitor 5 may be connected to the bus bar 3 in a different manner from that exemplified in the above embodiment. For example, the connection terminals 51 and 52 of the capacitor 5 may be connected to the bus bar 3 by soldering or welding.

[0124] The shape of busbar 3 is not limited to the illustrated shape. The number of terminals on busbars 31 and 32 is not limited to three. For example, busbars 31 and 32 may not have third terminals 31c and 32c. Alternatively, busbars 31 and 32 may have fourth terminals.

[0125] The housing 2 does not necessarily need to include the nut holder 21. For example, if the terminal block 1 does not include the nut 6, a structure supporting the nut 6 is unnecessary. In this case, the housing 2 may include a capacitor holder in place of the nut holder 21. The capacitor holder supports the frame 50 of the capacitor 5 and engages with the main body 20.

[0126] The housing 2 may not include a component housed in the housing portion 25 together with the frame 50. In this case, the frame 50 of the capacitor 5 may include an engaging portion that engages with the housing 2. The frame 50 housed in the housing portion 25 engages with the housing 2 via the engaging portion of the frame 50.

[0127] The housing 2 may also hold the frame 50 of the capacitor 5 in a manner different from the manner in which it is housed in the housing portion 25. For example, the housing 2 may include an engaging portion on the side surface of the main portion 22. In this case, the housing 2 can hold the frame 50 by engaging the engaging portion of the main portion 22 with the frame 50.

[0128] The contents disclosed in the above-mentioned embodiment and modified examples can be combined as appropriate.
