Summary of the Invention

Problems to be Solved by the Invention

[0004] When combining a plurality of storage batteries to form one storage battery unit, in order to avoid water droplets, dust, etc., it is necessary for the casings of all the storage batteries to have an airtight structure, or a large casing assuming future addition of storage batteries is required. Also, when connecting a plurality of storage batteries, a waterproof connector for connecting between the storage batteries is required. As a result, the unit price of the product increases and the product size becomes larger. For example, when stacking a plurality of storage batteries vertically, there is a method of connecting the connector of the upper storage battery and the connector of the lower storage battery by making the connector of the lower storage battery convex. In this method, in order to avoid damage to the connector of the lower storage battery, it is necessary to align the connector of the upper storage battery and the connector of the lower storage battery with high precision, and it is not easy to connect the connectors to each other.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a technique capable of easily connecting connectors to each other.

Means for Solving the Problems

[0006] According to one aspect of the present invention, there is provided an electrical equipment unit including a plurality of electrical equipment. Among the plurality of electrical equipment, a first electrical equipment includes a first housing, a first recess having a first opening on an outer surface of the first housing, a first connector disposed in the first recess, and a first guide portion for guiding movement of the first connector. In a state where the first opening and a second opening face each other, movement of the first connector in a direction substantially orthogonal to the direction in which the first opening faces is guided by the first guide portion, alignment of the first connector and the second connector is performed, and the first connector moves in the direction in which the first opening faces, so that the first connector is received in the second recess, and the first connector and the second connector are fitted together, thereby providing an electrical equipment unit.

[0007] Movement of the first connector in a direction substantially orthogonal to the direction in which the first opening faces is guided by the first guide portion, and alignment of the first connector of the first electrical equipment and the second connector of the second electrical equipment is performed. When the first connector moves in the direction in which the first opening faces, the first connector of the first electrical equipment is received in the second recess of the second electrical equipment, and the first connector of the first electrical equipment and the second connector of the second electrical equipment are fitted together. In a state where the first connector of the first electrical equipment and the second connector of the second electrical equipment are aligned, the first electrical Since the first connector of the first electrical device can be connected to the second connector of the second electrical device, it is possible to easily connect the connectors. Before the first connector of the first electrical device is received in the second recess of the second electrical device, the first connector of the first electrical device is disposed within the first housing and does not protrude outside the first housing, so the risk of damage to the first connector of the first electrical device is low. The second connector of the second electrical device is disposed within the second housing and does not protrude outside the second housing, so the risk of damage to the second connector of the second electrical device is low.

[0008] The first guide portion has a first base portion on which the first connector is installed and a first edge portion provided at at least a part of an outer edge of the first base portion. An inclined surface that inclines from a tip side to a non-tip side of the first edge portion and toward the outside of the first base portion is formed at a tip of the first edge portion. Therefore, even if the tip of the first edge portion of the first guide portion contacts a corner of the second recess of the second housing, the first connector can move smoothly.

[0009] The size of the first opening is larger than the size of the second opening. Therefore, even if a misalignment occurs in the alignment between the first opening of the first housing and the second opening of the second housing, it is easy to accommodate the first connector of the first electrical device in the second recess of the second electrical device.

[0010] The first electrical device includes a first hole portion that is formed in the first housing and opens in a direction substantially orthogonal to the direction in which the first opening faces, and a first lever that is disposed within the first hole portion and operates the movement of the first connector and the first guide portion. The first hole portion is connected to the first recess, and when the first lever is moved in the direction in which the first opening faces, the first connector and the first guide portion move in the direction in which the first opening faces. It is possible to operate the movement of the first connector and the first guide portion by the first lever.

[0011] The first electrical device includes a first lid portion that covers the first hole portion. The first lid portion has a first protrusion portion, and the movement of the first lever is restricted by the first protrusion portion, so that the movement of the first connector and the first guide portion is restricted. By restricting the movement of the first connector and the first guide portion, the connection between the first connector of the first electrical device and the second connector of the second electrical device is maintained in a good state, and a connection failure between the first connector of the first electrical device and the second connector of the second electrical device can be avoided. In addition, it is possible to prevent the first connector and the first guide portion from falling due to impact, vibration, etc., and to prevent the connection between the first connector of the first electrical device and the second connector of the second electrical device from being unintentionally released.

[0012] When the first connector and the second connector are fitted at an allowed position, the first lid portion can be attached to the first housing. By confirming that the first lid portion is attached to the first housing, the user can grasp that the connection between the first connector of the first electrical device and the second connector of the second electrical device has been completed in a correct state. It is possible to easily confirm whether the first connector of the first electrical device and the second connector of the second electrical device are securely connected, and the reliability of the connection between the connectors is improved.

[0013] A sealing portion is disposed between the first housing and the second housing, and the first opening and the second opening are disposed inside the sealing portion. The sealing portion prevents water droplets, dust, etc. from entering the first housing through the first opening of the first housing, and also prevents water droplets, dust, etc. from entering the second housing through the second opening of the second housing.

[0014] One or more of the plurality of electrical devices, i.e., the third electrical device, includes a third housing, a third recess having a third opening on an outer surface of the third housing, a third connector disposed in the third recess, a second guide portion for guiding the movement of the third connector, and on the outer surface of the third housing A fourth recess having a fourth opening and a fourth connector disposed within the fourth recess, wherein the direction in which the third opening faces is opposite to the direction in which the fourth opening faces, and with the first opening and the fourth opening of the third electrical device adjacent to the first electrical device facing each other, movement of the first connector in a direction substantially orthogonal to the direction in which the first opening faces is guided by the first guide portion, so that alignment of the first connector and the fourth connector of the third electrical device adjacent to the first electrical device is performed. By moving the first connector in the direction in which the first opening faces, the first connector is received within the fourth recess of the third electrical device adjacent to the first electrical device, and the first connector and the fourth connector of the third electrical device adjacent to the first electrical device are fitted together. With the second opening and the third opening of the third electrical device adjacent to the second electrical device facing each other, movement of the third connector in a direction substantially orthogonal to the direction in which the third opening faces is guided by the second guide portion, so that alignment of the second connector and the third connector of the third electrical device adjacent to the second electrical device is performed. By moving the third connector of the third electrical device adjacent to the second electrical device in the direction in which the third opening faces, the third connector is received within the second recess, and the second connector and the third connector of the third electrical device adjacent to the second electrical device are fitted together.

[0015] Since the first connector of the first electrical device and the fourth connector of the third electrical device can be connected in a state where alignment of the first connector of the first electrical device and the fourth connector of the third electrical device has been performed, it is possible to easily connect the connectors to each other. Since the second connector of the second electrical device and the third connector of the third electrical device can be connected in a state where alignment of the second connector of the second electrical device and the third connector of the third electrical device has been performed, it is possible to easily connect the connectors to each other.

[0016] The second guide portion has a second base portion where the second connector is installed and a second edge portion provided at at least a part of the outer edge of the second base portion. An inclined surface that inclines from the tip side to the non-tip side of the second edge portion and toward the outside of the second base portion is formed at the tip of the second edge portion. Therefore, even if the tip of the second edge portion of the second guide portion of the third electrical device contacts the corner of the second recess of the second electrical device, the third connector of the third electrical device can move smoothly.

[0017] The size of the first opening is larger than the size of the fourth opening, and the size of the third opening is larger than the size of the second opening. Even if a misalignment occurs in the alignment between the first opening of the first housing and the fourth opening of the third housing, it is easy to accommodate the first connector of the first electrical device in the fourth recess of the third electrical device adjacent to the first electrical device. Even if a misalignment occurs in the alignment between the second opening of the second housing and the third opening of the third housing, it is easy to accommodate the second connector of the second electrical device in the third recess of the third electrical device adjacent to the second electrical device.

[0018] The one or more third electrical devices are formed in the third housing and include a second hole portion that opens in a direction substantially orthogonal to the direction in which the third opening faces, and a second lever that is disposed in the second hole portion and operates the movement of the third connector and the second guide portion. The second hole portion is connected to the third recess, and when the second lever is moved in the direction in which the third opening faces, the third connector and the second guide portion move in the direction in which the third opening faces. It is possible to operate the movement of the third connector and the second guide portion by the second lever.

[0019] The one or more third electrical devices include a second lid portion that covers the second hole portion. The second lid portion has a second protrusion portion, and the movement of the second lever is restricted by the second protrusion portion, so that the movement of the third connector and the second guide portion is restricted. By restricting the movement of the third connector and the second guide portion, the second connector of the second electrical device and the third electrical The connection with the third connector of the machine can be maintained in a good state, and it is possible to avoid a poor connection between the second connector of the second electrical device and the third connector of the third electrical device. In addition, the fall of the third connector and the second guide portion can be suppressed, and it is possible to suppress the unintentional disconnection of the connection between the second connector of the second electrical device and the third connector of the third electrical device.

[0020] When the second connector is fitted with the third connector of the third electrical device adjacent to the second electrical device at an allowed position, the second lid portion can be attached to the third housing. By confirming that the second lid portion is attached to the third housing, the user can grasp that the connection between the second connector of the second electrical device and the third connector of the third electrical device adjacent to the second electrical device has been completed in a correct state. It is possible to easily confirm whether the second connector of the second electrical device and the third connector of the third electrical device adjacent to the second electrical device are securely connected, and the reliability of the connection between the connectors is improved.

[0021] A first sealing portion is disposed between the first housing and the third housing of the third electrical device adjacent to the first electrical device, and a second sealing portion is disposed between the second housing and the third housing of the third electrical device adjacent to the second electrical device. Inside the first sealing portion, the first opening and the fourth opening of the third electrical device adjacent to the first electrical device are disposed. Inside the second sealing portion, the second opening and the third opening of the third electrical device adjacent to the second electrical device are disposed. The first sealing portion suppresses water droplets, dust, etc. from entering the first housing through the first opening of the first housing of the first electrical device and suppresses water droplets, dust, etc. from entering the third housing through the fourth opening of the third housing of the third electrical device. The second sealing portion suppresses water droplets, dust, etc. from entering the second housing through the second opening of the second housing of the second electrical device and suppresses water droplets, dust, etc. from entering the third housing through the third opening of the third housing of the third electrical device.

FIGS. 13, 14, and 15 are explanatory diagrams for explaining an example of a method for connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. FIG. 13 shows a state where the opening 12 of the housing 11 of the storage battery 2A and the opening 1 02 of the housing 101 of the control unit 3 are facing each other. With the opening 12 of the housing 11 of the storage battery 2A and the opening 102 of the housing 101 of the control unit 3 facing each other, when the lever 20 of the storage battery 2A is moved in the direction in which the opening 12 of the housing 11 faces, the connector 15 and the guide portion 16 move in the direction in which the opening 12 of the housing 11 faces.

[0037] By moving the lever 20 of the storage battery 2A, the guide portion 16 slides (moves in a sliding manner) along the inner wall of the recess 13 of the housing 11. Therefore, the connector 15 can move smoothly in the direction in which the opening 12 of the housing 11 faces or in the direction opposite to the direction in which the opening 12 of the housing 11 faces. When the connector 15 moves in the direction in which the opening 12 of the housing 11 faces and the connector 15 is accommodated in the recess 103 of the housing 101 of the control unit 3, the tip of the edge 18 of the guide portion 16 contacts the corner of the recess 103 of the housing 101. An inclined surface is formed at the tip of the edge 18 of the guide portion 16. Therefore, even when the tip of the edge 18 of the guide portion 16 contacts the corner of the recess 103 of the housing 101, the connector 15 can move smoothly in the direction in which the opening 12 of the housing 11 faces.

[0038] As shown in FIG. 13, the size of the opening 12 of the housing 11 of the storage battery 2A is larger than the size of the opening 102 of the housing 101 of the control unit 3. Therefore, even if there is a deviation in the alignment between the opening 12 of the housing 11 of the storage battery 2A and the opening 102 of the housing 101 of the control unit 3, it is easy to accommodate the connector 15 of the storage battery 2A within the recess 103 of the housing 101 of the control unit 3.

[0039] FIG. 14 shows a state in which the connector 15 of the storage battery 2A is accommodated within the recess 103 of the housing 101 of the control unit 3. The movement of the connector 15 is guided by the guide portion 16. When the connector 15 is accommodated within the recess 103 of the housing 101, the guide portion 16 contacts the inner wall of the recess 103 of the housing 101, thereby aligning the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. That is, the guide portion 16 of the storage battery 2A fits into the recess 103 of the housing 101 of the control unit 3, and the position of the connector 15 of the storage battery 2A (position in the X-axis direction, position in the Y-axis direction) is corrected, thereby aligning the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. In this way, the movement of the connector 15 in a direction substantially orthogonal to the direction in which the opening 12 of the housing 11 faces (+Z-axis direction) by the guide portion 16 (XY plane direction) is guided, and the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are aligned. When the guide portion 16 of the storage battery 2A fits into the recess 103 of the housing 101 of the control unit 3, the position of the connector 15 with respect to the guide portion 16 of the storage battery 2A and the position of the connector 104 with respect to the recess 103 of the housing 101 of the control unit 3 are designed so that the connector 15 of the storage battery 2A can fit into the connector 104 of the control unit 3. Therefore, by aligning the connector 15 of the storage battery 2A and the connector 104 of the control unit 3, the connector 15 of the storage battery 2A is in a state where it can fit into the connector 104 of the control unit 3. That is, the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are in a state where they can be connected.

[0040] With the connectors 15 of the storage battery 2A and 104 of the control unit 3 aligned, the connector 15 of the storage battery 2A moves further in the direction in which the opening 12 of the housing 11 faces, thereby connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. That is, when the connector 15 of the storage battery 2A moves in the direction in which the opening 12 of the housing 11 faces, the connector 15 of the storage battery 2A is housed in the recess 103 of the housing 101 of the control unit 3, and the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are fitted together. In this way, it is possible to connect the connector 15 of the storage battery 2A and the connector 104 of the control unit 3, and it is possible to easily connect the connectors to each other.

[0041] As described above, by aligning the connector 15 of the storage battery 2A and the connector 104 of the control unit 3, variations in the components of the housing 11 of the storage battery 2A and the housing 101 of the control unit 3, and assembly variations can be absorbed. Since general connectors can be used for the connector 15 of the storage battery 2A and the connector 104 of the control unit 3, the options for connectors are expanded, and cost reduction can be achieved.

[0042] Before the connector 15 of the storage battery 2A is housed in the recess 103 of the housing 101 of the control unit 3, the connector 15 of the storage battery 2A is arranged in the housing 11 and does not protrude outside the housing 11. Therefore, the risk of the connector 15 of the storage battery 2A being damaged is low. For example, after placing the control unit 3 on the storage battery 2A, by moving the connector 15 of the storage battery 2A in a state where the alignment between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 is performed, damage to the connector 15 of the storage battery 2A can be avoided. The connector 104 of the control unit 3 is arranged in the housing 101 and does not protrude outside the housing 101, so the risk of the connector 104 of the control unit 3 being damaged is low. As shown in FIG. 14, the edge 18 of the guide portion 16 enters between the inner wall of the recess 103 of the housing 101 of the control unit 3 and the connector 104 of the control unit 3. Therefore, the edge 18 of the guide portion 16 is prevented from contacting the connector 104 of the control unit 3, and the edge 18 of the guide portion 16 does not hinder the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3.

[0043] When the opening 12 of the housing 11 of the storage battery 2A and the opening 102 of the housing 101 of the control unit 3 are facing each other, the lever 20 of the storage battery 2A can be moved between the first position and the second position. For example, the position of the lever 20 shown in FIG. 13 is the first position. When the base portion 17 of the guide portion 16 contacts the bottom surface of the recess 13 of the housing 11, the movement of the connector 15 and the guide portion 16 in the direction opposite to the direction in which the opening 12 of the housing 11 faces is restricted, and the movement of the lever 20 in the direction opposite to the direction in which the opening 12 of the housing 11 faces is also restricted.

[0044] For example, the position of the lever 20 shown in FIG. 14 is the second position. When the lever 20 moves to the second position, the connector 15 of the storage battery 2A is fitted to the connector 104 of the control unit 3, and the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 is completed. When the tip of the edge 18 of the guide portion 16 contacts the bottom surface of the recess 103 of the housing 101 of the control unit 3, the movement of the connector 15 and the guide portion 16 with respect to the direction in which the opening 12 of the housing 11 faces is restricted, and the movement of the lever 20 with respect to the direction in which the opening 12 of the housing 11 faces is also restricted. By moving the lever 20 from the second position in the direction opposite to the direction in which the opening 12 of the housing 11 faces, the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 is released.

[0045] The user can grasp the position of the connector 15 of the storage battery 2A by visually checking the position of the lever 20. By visually checking that the lever 20 has moved to the second position, the user can grasp that the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 has been completed in a correct state. In this way, it is possible to easily confirm whether the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are reliably connected, and the reliability of the connection between the connectors is improved.

[0046] FIG. 15 shows a state in which a lid portion 32 is attached to the housing 11 of the storage battery 2A. Specifically, the lid portion 32 is attached to the side surface of the housing 11 in a state where the lid portion 32 covers the hole portion 31 of the housing 11. The lid portion 32 may be attached to the side surface of the housing 11 by fitting the lid portion 32 into a recess provided on the side surface of the housing 11. After the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 is completed, the user attaches the lid portion 32 to the housing 11 of the storage battery 2A. The protrusion 33 of the lid portion 32 is in contact with the lever 20, and the movement of the lever 20 is restricted by the protrusion 33 of the lid portion 32. That is, the lever 20 is locked by the protrusion 33 of the lid portion 32. Since the movement of the lever 20 is restricted by the protrusion 33 of the lid portion 32, the movement of the connector 15 and the guide portion 16 is restricted. Therefore The connector 15 and the guide part 16 are locked. As a result, the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 is maintained in a good state, and it is possible to avoid a poor connection (poor contact) between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. In addition, it is possible to prevent the connector 15 and the guide part 16 of the storage battery 2A from falling due to impacts, vibrations, etc., and to prevent the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 from being unintentionally released.

[0047] When the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are fitted at an acceptable position, the lid part 32 can be attached to the housing 11. For example, when the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are not fitted and the position of the lever 20 shown in FIG. 15 is slightly downward, the protrusion 33 of the lid part 32 hits the tip surface of the lever 20, so that the lid part 32 cannot be attached to the housing 11. When the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are fitted at an acceptable position, the lever 20 and the protrusion 33 of the lid part 32 do not overlap in a direction substantially orthogonal to the direction in which the opening 12 of the housing 11 faces. In addition, when the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are fitted at an acceptable position, the position of the lever 20 is closer to the position of the protrusion 33 of the lid part 32 with respect to the control unit 3. By confirming that the lid part 32 is attached to the housing 11, the user can grasp that the connection between the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 has been completed in a correct state. In this way, it is possible to easily confirm whether or not the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 are securely connected, and the reliability of the connection between the connectors is improved.

[0048] A sealing portion may be disposed between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3. FIGS. 16A and 16B are plan views of the storage battery 2A when viewed from the upper surface side of the housing 11 of the storage battery 2A. A sealing portion 110 surrounding the opening 12 is provided on the upper surface of the housing 11. The sealing portion 110 is, for example, a packing. In FIG. 16A, the sealing portion 110 is disposed along the outer edge of the upper surface of the housing 11. In FIG. 16B, the sealing portion 110 is disposed around the opening 12 of the housing 11. For example, when viewed from the direction in which the opening 12 of the housing 11 faces, the opening 12 of the housing 11 and the sealing portion 110 may be similar in shape, and the size of the sealing portion 110 may be larger than the size of the opening 12 of the housing 11.

[0049] When the housing 101 of the control unit 3 contacts the sealing portion 110 disposed between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3, the sealing portion 110 is sandwiched between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3. With the opening 12 of the housing 11 of the storage battery 2A and the opening 102 of the housing 101 of the control unit 3 facing each other, the opening 12 of the housing 11 of the storage battery 2A and the opening 102 of the housing 101 of the control unit 3 are disposed inside the sealing portion 110. The sealing portion 110 prevents water droplets, dust, etc. from entering the housing 11 from the opening 12 of the housing 11 of the storage battery 2A, and also prevents water droplets, dust, etc. from entering the housing 101 from the opening 102 of the housing 101 of the control unit 3. Thereby, it is possible to connect the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 in a state where the airtightness inside the housing 11 of the storage battery 2A and the airtightness inside the housing 101 of the control unit 3 are ensured. Further, there is no need to install a waterproof connector between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3, and the cost for installing the waterproof connector is unnecessary. A sealing portion is not attached to the lower surface of the housing 101 of the control unit 3. The lower surface of the housing 101 of the control unit 3 does not require a sealing structure, and the cost of the control unit 3 can be reduced.

[0050] The connector 24 of the storage battery 2A and the connector 45 of the storage battery 2B may be connected. The method of connecting the connector 24 of the storage battery 2A and the connector 45 of the storage battery 2B is the same as the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. Although detailed description is omitted, an example of the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3 will be described. First, with the opening 22 of the housing 11 of the storage battery 2A and the opening 42 of the housing 41 of the storage battery 2B facing each other, the storage batteries 2A and 2B are installed so that the storage batteries 2A and 2B are adjacent to each other. The storage battery 2A may be placed on the storage battery 2B.

[0051] With the opening 22 of the housing 11 of the storage battery 2A and the opening 42 of the housing 41 of the storage battery 2B facing each other, when the lever 50 of the storage battery 2B is moved in the direction in which the opening 42 of the housing 41 faces, the connector 45 and the guide portion 46 move in the direction in which the opening 42 of the housing 41 faces. The direction in which the opening 42 of the housing 41 faces is the direction from the lower surface of the housing 41 to the upper surface of the housing 41. The movement of the connector 45 is guided by the guide portion 46, and when the connector 45 is accommodated in the recess 23 of the housing 11, the guide portion 46 contacts the inner wall of the recess 23 of the housing 11, thereby aligning the connector 24 of the storage battery 2A and the connector 45 of the storage battery 2B.

[0052] With the connectors 24 of the battery 2A and 45 of the battery 2B aligned, the connector 45 of the battery 2B is further moved in the direction in which the opening 42 of the housing 41 faces, so that the connector 24 of the battery 2A and the connector 45 of the battery 2B are connected. In this way, it is possible to connect the connector 24 of the battery 2A and the connector 45 of the battery 2B, and it is possible to easily connect the connectors. Since the connector 24 of the battery 2A is arranged inside the housing 11 and does not protrude outside the housing 11, the risk of the connector 24 of the battery 2A being damaged is low. Before the connector 45 of the battery 2B is housed in the recess 23 of the housing 11 of the battery 2A, the connector 45 of the battery 2B is arranged inside the housing 41 and does not protrude outside the housing 41. Therefore, the risk of the connector 45 of the battery 2B being damaged is low. For example, after placing the battery 2A on the battery 2B, by moving the connector 45 of the battery 2B in a state where the connector 24 of the battery 2A and the connector 45 of the battery 2B are aligned, damage to the connector 45 of the battery 2B can be avoided.

[0053] By providing a sealing portion 110 surrounding the opening 42 on the upper surface of the housing 41 of the battery 2B, the sealing portion 110 may be arranged between the housing 11 of the battery 2A and the housing 41 of the battery 2B. The configuration of the sealing portion 110 arranged between the housing 11 of the battery 2A and the housing 41 of the battery 2B is the same as the configuration of the sealing portion 110 arranged between the housing 11 of the battery 2A and the housing 101 of the control unit 3. That is, with the opening 22 of the housing 11 of the battery 2A and the opening 42 of the housing 41 of the battery 2B facing each other, the opening 22 of the housing 11 of the battery 2A and the opening 42 of the housing 41 of the battery 2B are arranged inside the sealing portion 110. The sealing portion 110 prevents water droplets, dust, etc. from entering the housing 11 through the opening 22 of the housing 11 of the battery 2A, and also prevents water droplets, dust, etc. from entering the housing 41 through the opening 42 of the housing 41 of the battery 2B.

[0054] The connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C may be connected. The method of connecting the connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C is the same as the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. Although detailed description is omitted, an example of the method of connecting the connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C will be described. First, with the opening 52 of the housing 41 of the storage battery 2B and the opening 72 of the housing 71 of the storage battery 2C facing each other, the storage batteries 2B and 2C are installed so that the storage batteries 2B and 2C are adjacent to each other. The storage battery 2C may be bolted to the concrete base portion, and the storage battery 2B may be placed on the storage battery 2C.

[0055] With the opening 52 of the housing 41 of the storage battery 2B and the opening 72 of the housing 71 of the storage battery 2C facing each other, when the lever 80 of the storage battery 2C is moved in the direction in which the opening 72 of the housing 71 faces, the connector 75 and the guide portion 76 move in the direction in which the opening 72 of the housing 71 faces. The direction in which the opening 72 of the housing 71 faces is the direction from the lower surface of the housing 71 to the upper surface of the housing 71. The movement of the connector 75 is guided by the guide portion 76, and when the connector 75 is accommodated in the recess 53 of the housing 41, the guide portion 76 contacts the inner wall of the recess 53 of the housing 41, so that the alignment between the connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C is performed.

[0056] With the connectors 54 of the storage battery 2B and 75 of the storage battery 2C aligned, as the connector 75 of the storage battery 2C further moves in the direction in which the opening 72 of the housing 71 faces, the connectors 54 of the storage battery 2B and 75 of the storage battery 2C are connected. In this way, it is possible to connect the connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C, and it is possible to easily connect the connectors. Since the connector 54 of the storage battery 2B is arranged inside the housing 41 and does not protrude outside the housing 41, the risk of damage to the connector 54 of the storage battery 2B is low. Before the connector 75 of the storage battery 2C is housed in the recess 53 of the housing 41 of the storage battery 2B, the connector 75 of the storage battery 2C is arranged inside the housing 71 and does not protrude outside the housing 71. Therefore, the risk of damage to the connector 75 of the storage battery 2C is low. For example, after placing the storage battery 2B on the storage battery 2C, by moving the connector 75 of the storage battery 2C in the state where the connector 54 of the storage battery 2B and the connector 75 of the storage battery 2C are aligned, damage to the connector 75 of the storage battery 2C can be avoided.

[0057] By providing a sealing portion 110 surrounding the opening 72 on the upper surface of the housing 71 of the storage battery 2C, the sealing portion 110 may be arranged between the housing 41 of the storage battery 2B and the housing 71 of the storage battery 2C. The configuration of the sealing portion 110 arranged between the housing 41 of the storage battery 2B and the housing 71 of the storage battery 2C is the same as the configuration of the sealing portion 110 arranged between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3. That is, with the opening 52 of the housing 41 of the storage battery 2B and the opening 72 of the housing 71 of the storage battery 2C facing each other, the opening 52 of the housing 41 of the storage battery 2B and the opening 72 of the housing 71 of the storage battery 2C are arranged inside the sealing portion 110. The sealing portion 110 prevents water droplets, dust, etc. from entering the housing 41 through the opening 52 of the housing 41 of the storage battery 2B, and also prevents water droplets, dust, etc. from entering the housing 71 through the opening 72 of the housing 71 of the storage battery 2C.

[0058] The connector 75 of the storage battery 2C and the connector 104 of the control unit 3 may be connected. For example, when the electric device unit 1 includes the storage battery 2C and the control unit 3, the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 are connected. The method of connecting the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 is the same as the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3. Although detailed description is omitted, an example of connecting the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 will be described. First, with the opening 72 of the housing 71 of the storage battery 2C and the opening 102 of the housing 101 of the control unit 3 facing each other, the storage battery 2C and the control unit 3 are installed so that the storage battery 2C and the control unit 3 are adjacent. The storage battery 2C may be bolted to the concrete base portion, and the control unit 3 may be placed on the storage battery 2C.

[0059] With the opening 72 of the housing 71 of the storage battery 2C and the opening 102 of the housing 101 of the control unit 3 facing each other, when the lever 80 of the storage battery 2C is moved in the direction in which the opening 72 of the housing 71 faces, the connector 75 and the guide portion 76 move in the direction in which the opening 72 of the housing 71 faces. The movement of the connector 75 is guided by the guide portion 76, and when the connector 75 is accommodated in the recess 103 of the housing 101, the guide portion 76 contacts the inner wall of the recess 103 of the housing 101, so that the alignment between the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 is performed. With the alignment between the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 being performed, when the connector 75 of the storage battery 2C further moves in the direction in which the opening 72 of the housing 71 faces, the connector 75 of the storage battery 2C and the connector 104 of the control unit 3 are connected. In this way, it is possible to connect the connector 75 of the storage battery 2C and the connector 104 of the control unit 3, and it is possible to easily connect the connectors. In this way, it is possible to connect the connector 75 of the storage battery 2C and the connector 104 of the control unit 3, and it is possible to easily connect the connectors.

[0060] By providing a sealing portion 110 that surrounds the opening 72 on the upper surface of the housing 71 of the storage battery 2C, the sealing portion 110 may be disposed between the housing 71 of the storage battery 2C and the housing 101 of the control unit 3. The configuration of the sealing portion 110 disposed between the housing 71 of the storage battery 2C and the housing 101 of the control unit 3 is the same as the configuration of the sealing portion 110 disposed between the housing 11 of the storage battery 2A and the housing 101 of the control unit 3. That is, with the opening 72 of the housing 71 of the storage battery 2C and the opening 102 of the housing 101 of the control unit 3 facing each other, the opening 72 of the housing 71 of the storage battery 2C and the opening 102 of the housing 101 of the control unit 3 are disposed inside the sealing portion 110. The sealing portion 110 prevents water droplets, dust, etc. from entering the housing 71 from the opening 72 of the housing 71 of the storage battery 2C, and also prevents water droplets, dust, etc. from entering the housing 101 from the opening 102 of the housing 101 of the control unit 3.

[0061] The connector 24 of the storage battery 2A and the connector 75 of the storage battery 2C may be connected. For example, when the electric device unit 1 includes the storage batteries 2A, 2C, and the control unit 3, the connector 24 of the storage battery 2A and the connector 75 of the storage battery 2C are connected. The method of connecting the connector 24 of the storage battery 2A and the connector 75 of the storage battery 2C is the same as the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3.

[0062] The connector 45 of the storage battery 2B and the connector 104 of the control unit 3 may be connected. For example, when the electric device unit 1 includes the storage batteries 2B, 2C, and the control unit 3, the connector 45 of the storage battery 2B and the connector 104 of the control unit 3 are connected. The method of connecting the connector 45 of the storage battery 2B and the connector 104 of the control unit 3 is the same as the method of connecting the connector 15 of the storage battery 2A and the connector 104 of the control unit 3.

[0063] A battery 2 having the same configuration as the battery 2A or 2B may be additionally provided between the battery 2A and the control unit 3. A battery 2 having the same configuration as the battery 2A or 2B may be additionally provided between the battery 2A and the battery 2B. A battery 2 having the same configuration as the battery 2A or 2B may be additionally provided between the battery 2B and the battery 2C. By adopting a vertical stacking structure for the electrical equipment unit 1, even if the battery capacity is increased, the installation area remains unchanged. Therefore, it is not necessary to secure a large installation space in anticipation of additional installation of the battery 2.
