[0012] The following describes embodiments of the present invention with reference to the drawings. Note that the shapes and materials of the components of the fuse box in the embodiments described below are merely examples and are not intended to limit the scope of the present invention.

[0013] First, Figures 1 and 2 show a fuse box 100 according to the present invention. Figure 1(a) is an overall perspective view of the fuse box 100, Figure 1(b) is an overall perspective view of the fuse box 100 attached to a distribution box 200, Figure 2(a) is a front view of the fuse box 100 attached to the distribution box 200, and Figure 2(b) is a plan view of the fuse box 100 attached to the distribution box 200.

[0014] The fuse box 100 is box-shaped and made entirely of synthetic resin, and includes a front wall 110, side walls 120, and a rear wall 130. As shown in FIG. 1(b), the fuse box 100 is attached to a distribution box 200 or the like that is mounted on a vehicle or the like, or is formed integrally with the distribution box 200 or the like, or a cover that covers an opening is attached to the fuse box 100 and then attached to the vehicle body. The interior of the fuse box 100 defines an accommodation space 140 that can accommodate a fuse 900 (described below). The accommodation space 140 is surrounded by the front wall 110, side walls 120, and rear wall 130 and is open at the top. An upper end 111 of the front wall 110 extends to connect the side walls 120 on both sides and is lower than upper ends 121 of the side walls 120 and an upper end 131 of the rear wall 130. An opening 112 that opens forward is defined above the upper end 111 of the front wall 110.

[0015] Also provided within the accommodation space 140 are a first connection portion 150 that supports the external terminal side of the fuse 900 (described later), and a second connection portion 160 that supports the external fuse side of the fuse 900. The second connection portion 160 is located higher than the first connection portion 150, and the second connection portion 160 and the first connection portion 150 are connected by a wall portion 170 that rises upward from the first connection portion 150. The wall portion 170 has a flat side surface and rises perpendicular to the first connection portion 150. An opening 112 is disposed in front of the connection portions (first connection portion 150, second connection portion 160). Note that the wall portion 170 rises perpendicular to the first connection portion 150, but is not limited thereto. As long as it rises upward from the first connection portion 150, it may have any configuration, such as rising obliquely.

[0016] The first connection portion 150 has a flat surface and is provided with a plurality of connection holes 151 into which the external terminals 920 of the fuse 900 are inserted. A space 152 is formed on the back surface side of the first connection portion 150, and as will be described later, a first connection terminal to be connected to the external terminal 920 of the fuse 900 can be inserted from below.

[0017] The second connection portion 160 is provided with a plurality of connection holes 161 through which second connection terminals that are to be connected to connection terminals 720 of the external fuse 700 of the fuse 900 can be inserted. A space 162 is formed on the back surface of the second connection portion 160, so that the second connection terminals that are to be connected to connection terminals 720 of the external fuse 700 can be inserted from below. The second connection portion 160 is provided with a flat lower step portion 163 on the front side and a flat upper step portion 164 on the rear side, with the upper step portion 164 being positioned higher than the lower step portion 163, and the second connection portion 160 is configured in a stepped shape with the lower step portion 163 and the upper step portion 164.

[0018] 1(b), when the fuse box 100 is attached to the distribution box 200, approximately the lower half of the fuse box 100 is recessed below the upper surface 210 of the distribution box 200. As a result, the upper end 111 of the front wall 110 of the fuse box 100 protrudes upward from the upper surface 210 of the distribution box 200, and the upper ends 121 of the side walls 120 and the upper end 131 of the rear wall 130 protrude further upward than the upper end 111 of the front wall 110.

[0019] 3 shows a fuse 900 that can be attached to the fuse box 100 of the present invention. FIG. 3(a) is a perspective view of the fuse 900, FIG. 3(b) is a side view of the fuse 900, and FIG. 3(c) is a front view of the fuse 900.

[0020] As shown in FIG. 3 , fuse 900 is a conventional fuse as described in Patent Document 1, and includes input terminal 910, external terminal 920, bus bar 930 disposed between input terminal 910 and external terminal 920, and housing 940 covering bus bar 930. A portion of bus bar 930 is provided with fusing portion 931. When an overcurrent flows from a power source such as a battery connected to input terminal 910, fusing portion 931 melts, thereby protecting loads such as various electrical components connected to external terminal 920. Furthermore, a confirmation window 950 provided in a portion of housing 940 allows confirmation of whether internal fusing portion 931 has melted. Furthermore, bus bar 930 is configured to allow attachment of external fuse 700, which includes fusing portion 730 and connection terminal 720. If an overcurrent flows from a power source such as a battery connected to the input terminal 910, the fusing portion 730 of the external fuse 700 will fuse, protecting the loads of various electrical equipment connected to the connection terminal 720.

[0021] 4 and 5 show the fuse 900 attached to the fuse box 100. Fig. 4(a) is a perspective view of the fuse 900 before it is inserted into the fuse box 100, Fig. 4(b) is a perspective view of the fuse 900 attached to the fuse box 100, Fig. 5(a) is a plan view of the fuse 900 attached to the fuse box 100, and Fig. 5(b) is a cross-sectional view taken along the line A-A.

[0022] As shown in Fig. 4, the fuse 900 is accommodated in the accommodation space 140 of the fuse box 100 from above so that the external terminal 920 extending downward of the fuse 900 is inserted into the connection hole 151 of the first connection portion 150 of the fuse box 100. In addition, the second connection terminal 209 is inserted from below into the connection hole 161 of the second connection portion 160, and the second connection terminal 209 protrudes upward from the second connection portion 160. Therefore, when the fuse 900 is accommodated in the fuse box 100, the second connection terminal 209 is inserted into and connected to the connection terminal 720 of the external fuse 700 of the fuse 900, as shown in Fig. 5(b).

[0023] As shown in FIGS. 4(b) and 5, when the fuse 900 is housed in the fuse box 100, the battery post B is connected to the input terminal 910 of the fuse 900. When the fuse 900 is housed in the fuse box 100, the rear wall 130 and the side wall 120 of the fuse box 100 guide the fuse 900 so as to surround it, making it easy to install the fuse 900 in the fuse box 100. An opening 112 is provided in front of the connection portions (first connection portion 150 and second connection portion 160) for connecting the fuse 900 to other connection terminals (first connection terminal and second connection terminal), allowing visual confirmation of the insertion state of the fuse 900 (e.g., whether the fuse 900 is fully inserted). Furthermore, as shown in FIG. 4(b), the inspection window 950 of the fuse 900 is exposed through the opening 112, allowing confirmation of whether the internal fusing portion 931 has blown.

[0024] Furthermore, the front wall 110 has an opening 112 on its upper side, but since the front wall 110 protrudes above the first connection portion 150, when the fuse 900 is attached to the fuse box 100, the front wall 110 surrounds the underside of the external terminal 920 of the fuse 900. Therefore, the front wall 110 can guide the external terminal 920 side of the fuse 900 when attaching the fuse 900 to the fuse box 100. Note that, although the first connection portion 150 and the second connection portion 160 are provided as connection portions for connecting the fuse 900, this is not limited thereto, and one connection portion or three or more connection portions may be provided depending on the configuration of the fuse 900. Furthermore, the external terminal 920 side of the fuse 900 is connected to the first connection portion 150, and the external fuse 700 side of the fuse 900 is connected to the second connection portion 160, but this is not limited thereto, and the first connection portion 150 and the second connection portion 160 may be connected to any location on the fuse 900.

[0025] Furthermore, the first connection portion 150 on the lower side of the fuse box 100 supports the external terminal 920 side of the fuse 900 that extends downward, and the second connection portion 160 on the upper side of the fuse box 100 supports the external fuse 700 side that is located above the external terminal 920 of the fuse 900. The wall portion 170 of the fuse box 100 is disposed so as to align with the fusing portion 931 and external terminal 920 of the fuse 900 that extend downward. Therefore, the first connection portion 150, wall portion 170, and second connection portion 160 of the fuse box 100 are configured in a continuous stepped shape, allowing the inverted L-shaped fuse 900 to be stably attached. Furthermore, the upper step portion 164 of the second connection portion 160 is positioned slightly above the lower step portion 163, so the upper step portion 164 can directly support the bottom side of the external fuse 700 of the fuse 900.

[0026] Furthermore, when the fuse 900 is attached to the fuse box 100, a portion of the external fuse 700 of the fuse 900 is located above the upper end 121 of the side wall 120 and the upper end 131 of the rear wall 130 of the fuse box 100. Therefore, even when the fuse 900 is attached to the fuse box 100, the external fuse 700 of the fuse 900 can be easily replaced.

[0027] In addition, the fuse 900 is used in such a manner that, with the fuse 900 attached to the fuse box 100, a first connection terminal (not shown) is attached to the external terminal 920 from below. The first connection terminal is electrically connected to loads such as various external electrical components. For example, if an overcurrent flows from a power source such as a battery connected to the input terminal 910, the fusing portion 931 melts, thereby protecting the loads such as various electrical components connected to the external terminal 920. Furthermore, the second connection terminal 209 connected to the connection terminal 720 of the external fuse 700 is electrically connected to loads such as various external electrical components via a connection wire (not shown) or the like. For example, if an overcurrent flows from a power source such as a battery connected to the input terminal 910, the fusing portion 730 of the external fuse 700 melts, thereby protecting the loads such as various electrical components connected to the second connection terminal 209.

[0028] The fuse box of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of rights.
