[0011] An example of the present disclosure will be described below with reference to the accompanying drawings. In the following description, terms indicating specific directions or positions (e.g., terms including "upper," "lower," "right," and "left") are used as necessary. However, the use of these terms is intended to facilitate understanding of the present disclosure with reference to the drawings, and the meanings of these terms do not limit the technical scope of the present disclosure. Furthermore, the following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the proportions of the dimensions and the like do not necessarily correspond to reality.

[0012] As shown in Fig. 1, a storage battery unit 1 according to an embodiment of the present disclosure includes a housing 2 and a storage battery 3 housed inside the housing 2. The housing 2 has, for example, a substantially rectangular parallelepiped shape.

[0013] 1 and 2, the housing 2 has a main body 10 capable of accommodating the storage battery 3 therein, and a terminal block 20 provided inside the main body 10. As shown in FIG. 2, the main body 10 has a first surface 101, a second surface 102 opposing the first surface 101, and a third surface 103 extending in a direction intersecting the first surface 101 and the second surface 102 (for example, a first direction Y) and connecting the first surface 101 and the second surface 102.

[0014] In this embodiment, the main body 10 is made up of a first housing portion 11, a second housing portion 12, and a base 13.

[0015] The first housing portion 11 is configured to be able to accommodate the storage battery 3 therein. The second housing portion 12 is attached to one end of the first housing portion 11 in the height direction (for example, Z direction; hereinafter referred to as the height direction Z), and the base 13 is attached to the other end of the first housing portion 11 in the height direction Z.

[0016] As shown in FIG. 2, the second housing portion 12 has a first accommodating portion 121, a second accommodating portion 122, a partition wall 123, and a sealing portion 124 therein.

[0017] The first accommodating portion 121 accommodates the terminal block 20. In the present embodiment, the first accommodating portion 121 has, for example, a substantially trapezoidal shape when viewed along the height direction Z. The first accommodating portion 121 has an accommodating surface 128 provided at an end far from the sealing portion 124 in a direction (e.g., second direction X) that intersects the first direction Y and the third surface 103, and the terminal block 20 is disposed adjacent to the accommodating surface 128. The accommodating surface 128 extends along the third surface 103. In addition to the terminal block 20, two connectors 60 (e.g., maintenance interface connectors) are disposed in the first accommodating portion 121.

[0018] The second housing portion 122 is configured to accommodate wiring 50 that electrically connects the storage battery 3 and an external device (not shown). The wiring 50 is connected to a connection portion 21 of a terminal block 20, which will be described later, via a sealing portion 124.

[0019] The partition wall 123 extends in a direction intersecting the first surface 101 and the third surface 103 to separate the first storage section 121 and the second storage section 122. The partition wall 123 has an opening 125 connected to the first storage section 121 and the second storage section 122. In this embodiment, the partition wall 123 is disposed so as to form an angle θ of 45 degrees with respect to the first surface 101.

[0020] Sealing portion 124 is disposed in opening 125 and seals opening 125. Sealing portion 124 prevents dust, water, and the like from entering first housing portion 121 through opening 125, and also prevents fire from spreading in the event of a fire breaking out in first housing portion 121.

[0021] In this embodiment, the sealing portion 124 is formed from a cable gland and is disposed at a position that satisfies the following conditions (1) to (3). (1) The first linear distance D1 from the center CP to the first surface 101 in the direction in which the partition wall 123 of the sealing portion 124 extends (for example, the direction in which the virtual line L3 in Figure 2 extends) is smaller than the second linear distance D2 from the center CP to the third surface 103. (2) The center CP of the sealing portion 124 is disposed closer to the third surface 103 in the second direction X than the centers of the storage surface 128 and the third surface 103. In other words, a third linear distance D3 from the center CP of the sealing portion 124 to the storage surface 128 is shorter than the first linear distance D1. (3) The center CP of the sealing portion 124 is disposed at approximately the center of the first surface 101 and the second surface 102 in the first direction Y.

[0022] A first inlet 126 is provided on the first surface 101 of the second housing portion 12, and a second inlet 127 is provided on the third surface 103 of the second housing portion 12. As an example, each of the first inlet 126 and the second inlet 127 has a substantially circular shape, is connected to the second accommodating portion 122 and the outside of the main body 10, and is configured to be able to draw the wiring 50 into the second accommodating portion 122.

[0023] The first inlet 126 is disposed closer to the third surface 103 than a first imaginary line L1 that passes through the center CP in the extension direction of the partition wall 123 of the sealing portion 124 (for example, the extension direction of the imaginary line L3 in FIG. 2) and extends in the first direction Y. The second inlet 127 is disposed closer to the first surface 101 than a second imaginary line L2 that passes through the center CP of the sealing portion 124 and extends in the second direction X.

[0024] The terminal block 20 has a connection portion 21 to which wiring 50 can be connected, which electrically connects the storage battery 3 and an external device (not shown). The terminal block 20 is disposed on the second imaginary straight line L2. The connection portion 21 is disposed closer to the second surface 102 in the first direction Y than the second imaginary straight line L2.

[0025] The housing 2 and the storage battery unit 1 can provide the following effects.

[0026] The housing (2) includes a main body (10) capable of accommodating a storage battery (3) therein, and a terminal block (20) provided inside the main body (10) and having a connection portion (21) to which wiring (50) can be connected, electrically connecting the storage battery (3) and an external device. The main body (10) includes a first accommodating portion (121) that accommodates the terminal block (20), a second accommodating portion (122) in which the wiring (50) can be arranged, a partition wall (123) that separates the first accommodating portion (121) and the second accommodating portion (122), an opening (125) provided in the partition wall (123), a sealing portion (124) that seals the opening (125), a first inlet (126) provided on the first surface (101) and capable of drawing the wiring (50) into the second accommodating portion (122), and a second inlet (127) provided on the third surface (103) and capable of drawing the wiring (50) into the second accommodating portion (122). The first inlet (126) passes through a center (CP) of the sealing portion (124) and is positioned closer to the third surface (103) than a first imaginary line (L1). The second inlet 127 passes through the center CP of the sealing portion 124 and is disposed closer to the first surface 101 than the second imaginary straight line L2. The terminal block 20 is disposed on the second imaginary straight line L2, and the connection portion 21 is disposed closer to the second surface 102 than the second imaginary straight line L2. With this configuration, the first accommodating portion 121 and the second accommodating portion 122 can be made smaller while ensuring an installation space in the first accommodating portion 121 for connecting the wiring 50 to the connection portion 21 of the terminal block 20. As a result, a housing that can be made smaller can be realized.

[0027] A first linear distance D1 from the center CP of the sealing portion 124 to the first surface is shorter than a second linear distance D2 from the center CP of the sealing portion 124 to the third surface 103. With this configuration, the first accommodating portion 121 and the second accommodating portion 122 can be more reliably made smaller while ensuring construction space in the first accommodating portion 121 for connecting the wiring 50 to the connection portion 21 of the terminal block 20.

[0028] The partition wall 123 is provided at an angle of 45 degrees with respect to the first surface 101, and the sealing portion 124 is configured as a cable gland. With this configuration, the first accommodating portion 121 and the second accommodating portion 122 can be made more compact while ensuring construction space in the first accommodating portion 121 for connecting the wiring 50 to the connection portion 21 of the terminal block 20.

[0029] The first accommodating portion 121 is provided at an end farther from the sealing portion 124 in the second direction, extends along the third surface 103, and has an accommodating surface 128 adjacent to which the terminal block 20 is disposed. The center CP of the sealing portion 124 is disposed closer to the third surface 103 in the second direction than the centers of the accommodating surface 128 and the third surface 103. With this configuration, the first accommodating portion 121 and the second accommodating portion 122 can be more reliably made smaller while still ensuring construction space in the first accommodating portion 121 for connecting the wiring 50 to the connection portion 21 of the terminal block 20.

[0030] The center CP of the sealing portion 124 is disposed in the first direction at approximately the center of the first surface 101 and the second surface 102. With this configuration, the first accommodating portion 121 and the second accommodating portion 122 can be more reliably made smaller while ensuring construction space in the first accommodating portion 121 for connecting the wiring 50 to the connection portion 21 of the terminal block 20.
