The fuse housing 53 has an insertion hole 57 formed in its top, and the fuse 54 is inserted into the insertion hole 57, whereby the fuse 54 is connected to the fuse terminal portion 56 of the extension bus bar 52.

[0043] The extension block 51 is attached to the side of the separate bus bar 31 opposite to the first terminal portion 34. As a result, the joint portion 55 of the extension bus bar 52 is joined to the separate bus bar 31, and the extension bus bar 52 having the fuse terminal portion 56 to which the fuse 54 is connected is provided on the separate bus bar 31.

[0044] The additional block 30B includes an extension block 51 capable of mounting a large fuse 58. The large fuse 58 is connected to a fuse terminal portion 56 of the extension bus bar 52 by being inserted into an insertion hole 57 of a fuse housing 53 of the extension block.

[0045] In the additional block 30C, the fuse terminal portion 56 is formed integrally with the separate bus bar 31, and the fuse terminal portion 56 is accommodated in the fuse cavity 44 formed in the separate housing 40. In this additional block 30C, the fuse 54 attached to the fuse cavity 44 is connected to the fuse terminal portion 56 formed integrally with the separate bus bar 31.

[0046] The other parts of the additional blocks 30B and 30C are the same as those of the additional block 30A, and therefore will not be described.

[0047] FIG. 5 is an exploded perspective view of the fuse block. 5, the fuse block 60 includes a fuse housing 61, a plurality of first electric wires 62, a power distribution connector 63, and a second electric wire 64. The fuse housing 61 has a plurality of insertion holes 65 in an upper portion thereof, and fuses 66 are inserted and attached into these insertion holes 65. The first electric wires 62 have terminals 62a at one end, and these terminals 62a are inserted and accommodated in the fuse housing 61 from below.

[0048] The power distribution connector 63 is composed of a plug 63a and a receptacle 63b, and the first electric wire 62 is connected to the plug 63a by inserting a terminal (not shown) provided at the other end of the first electric wire 62 into the plug 63a. A terminal 64a provided at one end of the second electric wire 64 is inserted into the receptacle 63b of the power distribution connector 63 for connection.

[0049] In the power distribution connector 63, a terminal of a first electric wire 62 housed in the plug 63a is connected to a terminal 64a of a second electric wire 64 housed in the receptacle 63b by fitting the plug 63a and the receptacle 63b together. A terminal 67 having a fastening hole 67a is connected to the other end of the second electric wire 64.

[0050] Terminals 68a provided at the ends of electric wires 68 extending from various devices from the lower part of the fuse housing 61 of the fuse block 60 are inserted and accommodated in the fuse housing 61. The terminals 68a of the electric wires 68 and the terminals 62a of the first electric wire 62 are electrically connected via a fuse 66 attached to the fuse housing 61.

[0051] The power supply block 100 according to this embodiment is constructed by assembling additional blocks 30A, 30B, 30C and a fuse block 60 to a main block 10 (see FIGS. 1 and 2).

[0052] To assemble the additional blocks 30A and 30B to the main block 10, the second terminal portion 35 of the separate bus bar 31 is aligned with the first bus bar 12 exposed on one side of the main block 10 so that the fastening holes 28 and 35a are in communication with each other. Next, the bolts 17 are inserted into the fastening holes 28 and 35a and screwed into the nuts 25 of the bus bar accommodating portion 23A. As a result, the first bus bar 12 held in the bus bar accommodating portion 23A and the separate bus bars 31 of the additional blocks 30A and 30B are fastened together by the bolts 17. In this manner, the additional blocks 30A and 30B are assembled to the main block 10, and the separate bus bars 31 of the additional blocks 30A and 30B are electrically connected to the first bus bar 12.

[0053] To assemble the additional block 30C to the main block 10, the second terminal portion 35 of the separate bus bar 31 is aligned with the second bus bar 13 exposed on the other side of the main block 10 so that the fastening holes 28, 35a are in communication with each other. Next, the bolt 17 is inserted through the fastening holes 28, 35a and screwed into the nut 25 of the bus bar accommodating portion 23B. This causes the second bus bar 13 held in the bus bar accommodating portion 23B and the separate bus bar 31 of the additional block 30C to be fastened together by the bolt 17. In this manner, the additional block 30C is assembled to the main block 10, and the separate bus bar 31 of the additional block 30C is electrically connected to the second bus bar 13.

[0054] Furthermore, in the fuse block 60, the terminal 67 of the second electric wire 64 is positioned relative to the second bus bar 13 exposed on the other side surface of the main block 10 so that the fastening holes 28, 67a communicate with each other, and the bolt 17 is inserted into the fastening holes 28, 67a and screwed into the nut 25 of the bus bar accommodating portion 23B. Then, the second bus bar 13 held in the bus bar accommodating portion 23B and the terminal 67 of the second electric wire 64 of the fuse block 60 are fastened together by the bolt 17. As a result, the fuse block 60 is assembled to the main block 10, and the second electric wire 64 of the fuse block 60 is electrically connected to the second bus bar 13.

[0055] Here, a power supply block according to a reference example will be described. Fig. 6 is a perspective view of a power supply block according to a reference example, and Fig. 7 is an exploded perspective view of the power supply block according to a reference example.

[0056] 6 and 7, a power supply block 1 according to the reference example includes a housing 2, into which a plurality of bus bars 3, 4 are inserted and accommodated from the lower side. Various fuses 5 of different sizes and shapes are attached to the upper part of the housing 2 and connected to the bus bars 3, 4 accommodated in the housing 2.

[0057] In the power supply block 1 according to this reference example, various fuses 5 of different sizes and shapes are attached, which complicates the housing 2 and the bus bars 3 and 4, resulting in increased costs. Also, in this power supply block 1, the size, shape, and number of fuses 5 that can be attached to the housing 2 are predetermined. For this reason, it is difficult to mount different fuses to install the power supply block 1 in vehicles of different grades, or to expand functions by increasing the number of parts.

[0058] In contrast, according to the power supply block 100 of this embodiment, the main block 10 holds the first bus bar 12 and the second bus bar 13 with one side exposed, so that the second terminal portion 35 of the separate bus bar 31 equipped with the fuse terminal portion 56 of the additional blocks 30A to 30C can be easily connected to the first bus bar 12 or the second bus bar 13 with one side exposed, thereby expanding the functionality of the power supply block 100.

[0059] Furthermore, by fastening terminal 67 at the other end of second electric wire 64 of fuse block 60 to first bus bar 12 or second bus bar 13, a fuse function can be easily added together with additional blocks 30A to 30C.

[0060] That is, the power supply block 100 according to this embodiment can be made to be more versatile and expandable than a power supply block having a housing or bus bars with a special shape.

[0061] Moreover, the first bus bars 12 and the second bus bars 13 to which the separate bus bars 31 of the additional blocks 30A to 30C and the terminals 67 of the fuse block 60 can be connected are accommodated in parallel in the main housing 11 of the main block 10. Therefore, it is possible to achieve a compact overall design while ensuring good versatility.

[0062] In addition, a translucent cover 50 is attached to the separate housing 40 of the additional blocks 30A to 30C in a position covering the fusible portion 33 of the separate bus bar 31, so that the state of the fusible portion 33 of the separate bus bar 31 in the additional blocks 30A to 30C can be easily visually confirmed through the translucent cover 50.

[0063] Second embodiment Next, a power supply block according to a second embodiment will be described. The same structural parts as those in the first embodiment are given the same reference numerals and the description thereof will be omitted. Fig. 8 is a perspective view of a power supply block according to the second embodiment, and Fig. 9 is a diagram showing a main block, where (a) is a perspective view and (b) is an exploded perspective view.

[0064] 8, 9(a) and 9(b), in a power supply block 200 according to the second embodiment, a main block 10 includes a main housing 11 in which a first bus bar accommodating portion 23A and a second bus bar accommodating portion 23B are formed continuously in the longitudinal direction on either side of a fusible element accommodating portion 22. The first bus bar 12 and the second bus bar 13 accommodated in the first bus bar accommodating portion 23A and the second bus bar accommodating portion 23B have bent ends on the mounting side to the fusible element accommodating portion 22, where fixing holes 29 are formed, and the bent ends are inserted into the fusible element accommodating portion 22 to be accommodated therein.

[0065] In this main block 10, the second terminal portion 35 of the separate bus bar 31 of the additional blocks 30A and 30B is fastened to the first bus bar 12 accommodated in the first bus bar accommodating portion 23A, and the second terminal portion 35 of the separate bus bar 31 of the additional block 30C and the terminal 67 of the second electric wire 64 of the fuse block 60 are fastened to the second bus bar 13 accommodated in the second bus bar accommodating portion 23B. As a result, the additional blocks 30A to 30C and the fuse block 60 are assembled in a state of being arranged in a row to the first bus bar accommodating portion 23A and the second bus bar accommodating portion 23B which are continuously formed in the longitudinal direction with the fusible element accommodating portion 22 sandwiched therebetween.

[0066] In this way, according to the power supply block 200 according to the second embodiment, the first bus bar accommodating portion 23A accommodating the first bus bar 12 and the second bus bar accommodating portion 23B accommodating the second bus bar 13 are formed continuously in the longitudinal direction, sandwiching the fusible element accommodating portion 22 that accommodates the main fusible element 14. Therefore, it is possible to achieve a thin overall configuration while ensuring good versatility.

[0067] Next, a power supply block 200 according to a modification of the second embodiment will be described. Fig. 10 is a perspective view of a power supply block according to a modified example of the second embodiment. Fig. 11 is a view showing a main block, (a) being a perspective view and (b) being an exploded perspective view. Fig. 12 is a schematic plan view and a partially enlarged view showing a bent state of a flexible portion of the main block.

[0068] 10, 11(a) and 11(b), in a power supply block 200A according to a modification of the second embodiment, flexible portions F are provided in parts of the first bus bar accommodating portion 23A and the second bus bar accommodating portion 23B that are continuously formed in the longitudinal direction across the fusible element accommodating portion 22. In these flexible portions F, the first bus bar accommodating portion 23A and the second bus bar accommodating portion 23B are each flexible and bendable in a direction perpendicular to the surface.

[0069] Furthermore, in this power supply block 200A, as shown in FIG. 12, the first bus bar 12 and the second bus bar 13 accommodated in the first bus bar accommodating portion 23A and the second bus bar accommodating portion 23B can be bent at the position of the flexible portion F to match, for example, the shape of the installation space, thereby further enhancing versatility.

[0070] It should be noted that the flexible portion F needs to be provided on at least one of the first bus bar 12 and the second bus bar 13; however, by providing the flexible portion F on both the first bus bar 12 and the second bus bar 13, the shape of the power supply block 200A can be flexibly adapted to the shape of the installation space, etc.
