Summary of the Invention

Problems to be Solved by the Invention

[0004] When a plurality of storage batteries are combined to form one storage battery unit, in order to avoid water droplets, dust, etc., the casings of all the storage batteries need 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. Therefore, the unit price of the product becomes high, or the size of the product becomes large. For example, when a plurality of storage batteries are stacked 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 the connection between the connectors is not easy.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a technology 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 has a first housing, a first connector and a first cable disposed in the first housing, a first connector portion capable of changing the position and posture of the first connector with respect to the first housing, and a first opening formed in the first housing and exposing the first connector. Among the plurality of electrical equipment, a second electrical equipment has a second housing, a second connector portion having a second connector and a second cable disposed in the second housing, and a second opening formed in the second housing and exposing the second connector. In a state where the first opening and the second opening face each other, when the first connector is moved, the first connector can be connected to the second connector, and an electrical equipment unit is provided.

[0007] Since the first connector of the first electrical equipment can be connected to the second connector of the second electrical equipment by moving the first connector of the first electrical equipment, it is possible to easily connect the connectors. The first connector of the first electrical equipment is disposed in the first housing and does not protrude outside the first housing. The second connector of the second electrical equipment is disposed in the second housing and does not protrude outside the second housing. When connecting the first connector of the first electrical equipment and the second connector of the second electrical equipment, the risk of damage to the first connector of the first electrical equipment and the second connector of the second electrical equipment is low.

[0008] The first electrical equipment includes a first hole portion formed in the first housing and disposed in a direction orthogonal to the direction in which the first opening faces, and a first lid portion covering the first hole portion. The first hole portion is connected to a space in the first housing where the first connector is disposed. The user can avoid a connection failure between the first connector of the first electrical equipment and the second connector of the second electrical equipment by visually checking the connection state between the first connector of the first electrical equipment and the second connector of the second electrical equipment through the first hole portion of the first housing of the first electrical equipment.

[0009] The position and orientation of the second connector with respect to the second housing are fixed. As a result, the user can connect the connectors with one hand.

[0010] 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 of the first electrical device from the first opening of the first housing of the first electrical device, and also prevents water droplets, dust, etc. from entering the second housing of the second electrical device from the second opening of the second housing of the second electrical device.

[0011] One or more of the plurality of electrical devices, i.e., the third electrical device, has a third housing, a third connector and a third cable disposed inside the third housing, a third connector portion capable of changing the position and orientation of the third connector with respect to the third housing, a third opening formed in the third housing and exposing the third connector, a fourth connector portion having a fourth connector and a fourth cable disposed inside the third housing, and a fourth opening formed in the third housing and exposing the fourth connector. In a state where the first opening and the fourth opening of the third electrical device adjacent to the first electrical device are opposed, when the first connector is moved, the first connector can be connected to the fourth connector of the third electrical device adjacent to the first electrical device. In a state where the second opening and the third opening of the third electrical device adjacent to the second electrical device are opposed, when the third connector of the third electrical device adjacent to the second electrical device is moved, the third connector of the third electrical device adjacent to the second electrical device can be connected to the second connector.

[0012] When the first connector of the first electrical device is moved, the first connector of the first electrical device can be connected to the fourth connector of the third electrical device adjacent to the first electrical device, so that it is possible to easily connect the connectors. When the third connector of the third electrical device adjacent to the second electrical device is moved, the third connector of the third electrical device adjacent to the second electrical device can be connected to the second connector of the second electrical device, so that it is possible to easily connect the connectors. The first connector of the first electrical device is disposed within the first housing and does not protrude outside the first housing. The second connector of the second electrical device is disposed within the second housing and does not protrude outside the second housing. The third connector and the fourth connector of the third electrical device are disposed within the third housing and do not protrude outside the third housing. When connecting the first connector of the first electrical device and the fourth connector of the third electrical device, the risk of damage to the first connector of the first electrical device and the fourth connector of the third electrical device is low. When connecting the second connector of the second electrical device and the third connector of the third electrical device, the risk of damage to the second connector of the second electrical device and the third connector of the third electrical device is low.

[0013] The one or more third electrical devices include a second hole portion formed in the third housing and disposed in a direction orthogonal to the direction in which the third opening faces, and a second lid portion covering the second hole portion. The second hole portion communicates with a space in the third housing where the third connector is disposed. The user can avoid a connection failure between the second connector of the second electrical device and the third connector of the third electrical device by visually checking the connection state between the second connector of the second electrical device and the third connector of the third electrical device through the second hole portion of the third housing of the third electrical device.

[0014] The position and orientation of the fourth connector with respect to the third housing are fixed. Thereby, the user can perform the connection work of the connectors with one hand.

[0015] 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. 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. The first opening and the fourth opening of the third electrical device adjacent to the first electrical device are disposed inside the first sealing portion. The second opening and the third opening of the third electrical device adjacent to the second electrical device are disposed inside the second sealing portion. The first sealing portion prevents water droplets, dust, etc. from entering the first housing from the first opening of the first housing of the first electrical device and also prevents water droplets, dust, etc. from entering the third housing from the fourth opening of the third housing of the third electrical device. The second sealing portion prevents water droplets, dust, etc. from entering the second housing from the second opening of the second housing of the second electrical device and also prevents water droplets, dust, etc. from entering the third housing from the third opening of the third housing of the third electrical device.

[0016] With one of the third openings of two adjacent third electrical devices among the plurality of third electrical devices facing the fourth opening of the other of the two adjacent third electrical devices, when one of the third connectors of the two adjacent third electrical devices is moved, the one of the third connectors of the two adjacent third electrical devices can be connected to the fourth connector of the other of the two adjacent third electrical devices. Thereby, it is possible to easily connect the connectors to each other.

[0017] 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. 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. A third sealing portion is disposed between one of the third housings of the two adjacent third electrical devices and the other of the third housings of the two adjacent third electrical devices. 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. Inside the third sealing portion, one of the third openings of the two adjacent third electrical devices and the fourth opening of the other of the two adjacent third electrical devices are disposed. The first sealing portion prevents water droplets, dust, etc. from entering the first housing from the first opening of the first housing of the first electrical device, and also prevents water droplets, dust, etc. from entering the third housing from the third opening of the third housing of the third electrical device adjacent to the first electrical device. The second sealing portion prevents water droplets, dust, etc. from entering the second housing from the second opening of the second housing of the second electrical device, and also prevents water droplets, dust, etc. from entering the third housing from the fourth opening of the third housing of the third electrical device adjacent to the second electrical device. The third sealing portion prevents water droplets, dust, etc. from entering the third housing from the third opening of one of the two adjacent third electrical devices, and also prevents water droplets, dust, etc. from entering the third housing from the fourth opening of the other of the two adjacent third electrical devices.

[0018] One of the first electrical device and the second electrical device is a storage battery, and the other of the first electrical device and the second electrical device is a control unit.

A sealing portion 43 that surrounds the hole portion 41 is provided on the side surface of the housing 31. Since the storage battery 2B has the same configuration as the storage battery 2A, a detailed description of the configuration of the storage battery 2B is omitted.

[0030] FIG. 5A is a perspective view showing the configuration of the storage battery 2C. FIG. 5B is a plan view of the storage battery 2C when viewed from the direction of arrow Z3 in FIG. 5A. The storage battery 2C includes a housing 51, a connector portion 54 having a connector 52 and a cable 53 disposed within the housing 51, and an opening 55 formed in the housing 51 to expose the connector 52. The connector 52 is, for example, a female connector. The housing 51 is, for example, cube-shaped, but may have other shapes. The opening 55 is formed in the upper surface of the housing 51. For example, when viewed from the direction in which the opening 55 faces, the connector 52 and the opening 55 may be similar in shape, and the opening 55 is larger than the connector 52. A sealing portion 56 surrounding the opening 55 is provided on the upper surface of the housing 51. The sealing portion 56 is, for example, a packing. The connector 52 is fixed to the housing 51. Therefore, in the storage battery 2C, the position and orientation of the connector 52 with respect to the housing 51 are fixed. Further, the cable 53 may be fixed to the housing 51.

[0031] The connector portion 54 is disposed within the housing 51 of the storage battery 2C. By suppressing the intrusion of water droplets, dust, etc. from the outside by the housing 51 of the storage battery 2C, it is possible to prevent water droplets, dust, etc. from the outside from coming into contact with the connector portion 54.

[0032] <Configuration of the control unit> FIG. 6A is a perspective view showing the configuration of the control unit 3. FIG. 6B is a plan view of the control unit 3 when viewed from the direction of arrow Z4 in FIG. 6A. The control unit 3 includes a housing 61, a connector unit 64 having a connector 62 and a cable 63 disposed within the housing 61, and an opening 65 formed in the housing 61 to expose the connector 62. The housing 61 is, for example, cube-shaped, but may have other shapes. The connector 62 is, for example, a male connector. The opening 65 is formed in the lower surface of the housing 61. For example, when viewed from the direction in which the opening 65 faces, the connector 62 and the opening 65 may be similar in shape, and the opening 65 may be larger than the connector 62. The control unit 3 includes a connector unit 64 capable of changing the position and orientation of the connector 62 with respect to the housing 61. The connector 62 and the cable 63 are not fixed to the housing 61, and the position and orientation of the connector 62 can be changed. Therefore, the connector 62 can be freely moved in all directions.

[0033] The control unit 3 includes a hole 66 formed in a side surface of the housing 61 and a lid portion 67. The hole 66 in the housing 61 is disposed in a direction orthogonal to the direction in which the opening 65 of the housing 61 faces. The hole 66 in the housing 61 communicates with the space in which the connector 62 within the housing 61 is disposed. The user can put a hand into the space in which the connector 62 within the housing 61 is disposed and freely move the connector 62.

[0034] A sealing portion 68 surrounding the hole portion 66 is provided on the side surface of the housing 61. The sealing portion 68 is, for example, a packing. FIG. 6C is a plan view of the control unit 3 when viewed from the direction of arrow X2 in FIG. 6A. In FIG. 6C, a lid portion 67 is attached to the side surface of the housing 61. The lid portion 67 may be attached to the side surface of the housing 61 on the side where the wiring pipe 5 is arranged. When the lid portion 67 is fixed to the housing 61 using screws or the like, by attaching the lid portion 67 to the side surface of the housing 61 on the side where the wiring pipe 5 is arranged, screws or the like are not visible from the front of the housing 61, and the design is improved. The lid portion 67 covers the hole portion 66 of the housing 61 and is in contact with the sealing portion 68. The sealing portion 68 is arranged between the housing 61 and the lid portion 67, and the hole portion 66 of the housing 61 is arranged inside the sealing portion 68. Sealing The portion 68 prevents water droplets, dust, etc. from entering the housing 61 from the hole portion 66 of the housing 61.

[0035] The connector 16 of the storage battery 2A and the connector 62 of the control unit 3 may be connected. An example of a method for connecting the connector 16 of the storage battery 2A and the connector 62 of the control unit 3 will be described. First, with the opening 19 of the housing 11 of the storage battery 2A and the opening 65 of the housing 61 of the control unit 3 facing each other, the storage battery 2A and the control unit 3 are installed so that the storage battery 2A and the control unit 3 are adjacent to each other. The control unit 3 may be placed on the storage battery 2A. With the opening 19 of the housing 11 of the storage battery 2A and the opening 65 of the housing 61 of the control unit 3 facing each other, when the connector 62 of the control unit 3 is moved, the connector 62 of the control unit 3 can be connected to the connector 16 of the storage battery 2A. Therefore, it is possible to easily connect the connectors. For example, in a state where the lid portion 67 does not cover the hole portion 66 of the housing 61, the user can put a hand into the space where the connector 62 inside the housing 61 is arranged through the hole portion 66 of the housing 61 and move the connector 62 of the control unit 3 to connect the connector 62 of the control unit 3 to the connector 16 of the storage battery 2A.

[0036] The connector 16 of the storage battery 2A is arranged inside the housing 11 and does not protrude outside the housing 11. Therefore, when connecting the connector 16 of the storage battery 2A and the connector 62 of the control unit 3, the risk of damage to the connector 16 of the storage battery 2A is low. The connector 62 of the control unit 3 is arranged inside the housing 61 and does not protrude outside the housing 61. Therefore, when connecting the connector 16 of the storage battery 2A and the connector 62 of the control unit 3, the risk of damage to the connector 62 of the control unit 3 is low. The user can avoid a poor connection (contact failure) between the connector 16 of the storage battery 2A and the connector 62 of the control unit 3 by visually checking the connection state between the connector 16 of the storage battery 2A and the connector 62 of the control unit 3 through the hole 66 in the housing 61 of the control unit 3.

[0037] Since the connector 16 is fixed to the housing 11, the user can connect the connector 62 of the control unit 3 to the connector 16 of the storage battery 2A with one hand. Therefore, it is possible to make the hole 66 in the housing 61 smaller compared to the case of connecting the connector 62 of the control unit 3 to the connector 16 of the storage battery 2A with both hands. The hole 66 in the housing 61 may be arranged on the side surface of the housing 61 on the side where the wiring pipe 5 is arranged. By arranging the hole 66 in the housing 61 on the side where the wiring pipe 5 is arranged, it becomes easy to secure a working space inside the housing 61.

[0038] When the housing 61 of the control unit 3 contacts the sealing portion 20 provided on the upper surface of the housing 11 of the storage battery 2A, the sealing portion 20 is sandwiched between the housing 11 of the storage battery 2A and the housing 61 of the control unit 3. Therefore, the sealing portion 20 is disposed between the housing 11 of the storage battery 2A and the housing 61 of the control unit 3. With the opening 19 of the housing 11 of the storage battery 2A and the opening 65 of the housing 61 of the control unit 3 facing each other, the opening 19 of the housing 11 of the storage battery 2A and the opening 65 of the housing 61 of the control unit 3 are disposed inside the sealing portion 20. The sealing portion 20 prevents water droplets, dust, etc. from entering the housing 11 from the opening 19 of the housing 11 of the storage battery 2A, and also prevents water droplets, dust, etc. from entering the housing 61 from the opening 65 of the housing 61 of the control unit 3. Thereby, it is possible to connect the connector 16 of the storage battery 2A and the connector 62 of the control unit 3 while ensuring the airtightness inside the housing 11 of the storage battery 2A and the airtightness inside the housing 61 of the control unit 3. Further, there is no need to install a waterproof connector between the housing 11 of the storage battery 2A and the housing 61 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 61 of the control unit 3. The lower surface of the housing 61 of the control unit 3 does not require a sealing structure, and the cost of the control unit 3 can be reduced.

[0039] The connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B may be connected. An example of a method for connecting the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B will be described. First, with the opening 15 of the housing 11 of the storage battery 2A and the opening 39 of the housing 31 of the storage battery 2B facing each other Then, the storage batteries 2A and 2B are installed such that the storage batteries 2A and 2B are adjacent to each other. The storage battery 2A may be placed on the storage battery 2B. With the opening 19 of the housing 11 of the storage battery 2A and the opening 39 of the housing 31 of the storage battery 2B facing each other, the connector 12 of the storage battery 2A can be connected to the connector 36 of the storage battery 2B by moving the connector 12 of the storage battery 2A. Therefore, it is possible to easily connect the connectors to each other. For example, in a state where the lid portion 22 does not cover the hole portion 21 of the housing 11, the user puts a hand into the space where the connector 12 in the housing 11 is disposed through the hole portion 21 of the housing 11 and moves the connector 12 of the storage battery 2A to connect the connector 12 of the storage battery 2A to the connector 36 of the storage battery 2B.

[0040] The connector 12 of the storage battery 2A is disposed in the housing 11 and does not protrude outside the housing 11. Therefore, when connecting the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B, the risk of damage to the connector 12 of the storage battery 2A is low. The connector 36 of the storage battery 2B is disposed in the housing 31 and does not protrude outside the housing 31. Therefore, when connecting the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B, the risk of damage to the connector 36 of the storage battery 2B is low. The user can avoid a poor connection between the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B by visually checking the connection state between the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B through the hole portion 21 of the housing 11 of the storage battery 2A.

[0041] Since the connector 36 is fixed to the housing 31, the user can perform the connection operation of the connector 12 of the storage battery 2A to the connector 36 of the storage battery 2B with one hand. Therefore, it is possible to make the hole portion 21 of the housing 11 smaller as compared with the case of performing the connection operation of the connector 12 of the storage battery 2A to the connector 36 of the storage battery 2B with both hands. The hole portion 21 of the housing 11 may be disposed on the side surface of the housing 11 on the side where the wiring pipe 5 is disposed. By disposing the hole portion 21 of the housing 11 on the side where the wiring pipe 5 is disposed, it becomes easy to secure a working space in the housing 11.

[0042] When the housing 11 of the storage battery 2A contacts the sealing portion 40 provided on the upper surface of the housing 31 of the storage battery 2B, the sealing portion 40 is sandwiched between the housing 11 of the storage battery 2A and the housing 31 of the storage battery 2B. Therefore, the sealing portion 40 is disposed between the housing 11 of the storage battery 2A and the housing 31 of the storage battery 2B. With the opening 15 of the housing 11 of the storage battery 2A and the opening 39 of the housing 31 of the storage battery 2B facing each other, the opening 15 of the housing 11 of the storage battery 2A and the opening 39 of the housing 31 of the storage battery 2B are disposed inside the sealing portion 40. The sealing portion 40 prevents water droplets, dust, etc. from entering the housing 11 from the opening 15 of the housing 11 of the storage battery 2A, and also prevents water droplets, dust, etc. from entering the housing 31 from the opening 39 of the housing 31 of the storage battery 2B. Thereby, it is possible to connect the connector 12 of the storage battery 2A and the connector 36 of the storage battery 2B while ensuring the airtightness inside the housing 11 of the storage battery 2A and the airtightness inside the housing 31 of the storage battery 2B. Further, there is no need to install a waterproof connector between the housing 11 of the storage battery 2A and the housing 31 of the storage battery 2B, and the cost for installing the waterproof connector is unnecessary.

[0043] The connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C may be connected. An example of a method for connecting the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C will be described. First, with the opening 35 of the housing 31 of the storage battery 2B and the opening 55 of the housing 51 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 2B may be placed on the storage battery 2C. With the opening 35 of the housing 31 of the storage battery 2B and the opening 55 of the housing 51 of the storage battery 2C facing each other, when the connector 32 of the storage battery 2B is moved, the connector 32 of the storage battery 2B can be connected to the connector 52 of the storage battery 2C. For this reason, it is possible to easily connect the connectors to each other. For example, in a state where the lid portion 42 does not cover the hole portion 41 of the housing 31, the user puts a hand into the space where the connector 32 inside the housing 31 is disposed from the hole portion 41 of the housing 31 and moves the connector 32 of the storage battery 2B to connect the connector 32 of the storage battery 2B to the connector 52 of the storage battery 2C.

[0044] Since the connector 32 of the storage battery 2B is disposed inside the housing 31 and does not protrude outside the housing 31, when connecting the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C, the risk of damage to the connector 32 of the storage battery 2B is low. Since the connector 52 of the storage battery 2C is disposed inside the housing 51 and does not protrude outside the housing 51, when connecting the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C, the risk of damage to the connector 52 of the storage battery 2C is low. The user can avoid a poor connection between the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C by visually checking the connection state between the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C through the hole 41 in the housing 31 of the storage battery 2B.

[0045] Since the connector portion 54 of the storage battery 2C is fixed, no hole portion and lid portion are provided on the side surface of the housing 51 of the storage battery 2C. Since the connector 52 is fixed to the housing 51, the user can connect the connector 32 of the storage battery 2B to the connector 52 of the storage battery 2C with one hand. Therefore, it is possible to make the hole 41 in the housing 31 smaller than in the case of connecting the connector 32 of the storage battery 2B to the connector 52 of the storage battery 2C with both hands. The hole 41 in the housing 31 may be disposed on the side surface of the housing 31 on the side where the wiring pipe 5 is disposed. By disposing the hole 41 in the housing 31 on the side where the wiring pipe 5 is disposed, it becomes easy to secure a working space inside the housing 31.

[0046] When the housing 31 of the storage battery 2B contacts the sealing portion 56 provided on the upper surface of the housing 51 of the storage battery 2C, the sealing portion 56 is sandwiched between the housing 31 of the storage battery 2B and the housing 51 of the storage battery 2C. Therefore, the sealing portion 56 is disposed between the housing 31 of the storage battery 2B and the housing 51 of the storage battery 2C. With the opening 35 of the housing 31 of the storage battery 2B and the opening 55 of the housing 51 of the storage battery 2C facing each other, the opening 35 of the housing 31 of the storage battery 2B and the opening 55 of the housing 51 of the storage battery 2C are disposed inside the sealing portion 56. The sealing portion 56 prevents water droplets, dust, etc. from entering the housing 31 through the opening 35 of the housing 31 of the storage battery 2B, and also prevents water droplets, dust, etc. from entering the housing 51 through the opening 55 of the housing 51 of the storage battery 2C. Thereby, it is possible to connect the connector 32 of the storage battery 2B and the connector 52 of the storage battery 2C while ensuring the airtightness inside the housing 31 of the storage battery 2B and the airtightness inside the housing 51 of the storage battery 2C. Further, it is not necessary to install a waterproof connector between the housing 31 of the storage battery 2B and the housing 51 of the storage battery 2C, and the cost for installing the waterproof connector is not required.

[0047] The connector 52 of the storage battery 2C and the connector 62 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 52 of the storage battery 2C and the connector 62 of the control unit 3 are connected. An example of a method for connecting the connector 52 of the storage battery 2C and the connector 62 of the control unit 3 will be described. First, with the opening 55 of the housing 51 of the storage battery 2C and the opening 65 of the housing 61 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 to each other. The control unit 3 may be placed on the storage battery 2C. With the opening 55 of the housing 51 of the storage battery 2C and the opening 65 of the housing 61 of the control unit 3 facing each other, by moving the connector 62 of the control unit 3, the connector 62 of the control unit 3 can be connected to the connector 52 of the storage battery 2C. Therefore, it is possible to easily connect the connectors to each other. For example, in a state where the lid portion 67 does not cover the hole portion 66 of the housing 61, the user can put a hand into the space where the connector 62 inside the housing 61 is arranged through the hole portion 66 of the housing 61 and move the connector 62 of the control unit 3 to connect the connector 62 of the control unit 3 to the connector 52 of the storage battery 2C.

[0048] The connector 52 of the storage battery 2C is arranged inside the housing 51 and does not protrude outside the housing 51. Therefore, when connecting the connector 52 of the storage battery 2C and the connector 62 of the control unit 3, the risk of damage to the connector 52 of the storage battery 2 C is low. The connector 62 of the control unit 3 is arranged inside the housing 61 and does not protrude outside the housing 61. Therefore, when connecting the connector 52 of the storage battery 2C and the connector 62 of the control unit 3, the risk of damage to the connector 62 of the control unit 3 is low. The user can avoid a connection failure between the connector 52 of the storage battery 2C and the connector 62 of the control unit 3 by visually checking the connection state between the connector 52 of the storage battery 2C and the connector 62 of the control unit 3 through the hole portion 66 of the housing 61 of the control unit 3.

[0049] Since the connector 52 is fixed to the housing 51, the user can connect the connector 62 of the control unit 3 to the connector 52 of the battery 2C with one hand. Therefore, it is possible to make the hole 66 of the housing 61 smaller compared to the case where the connection work of the connector 62 of the control unit 3 to the connector 52 of the battery 2C is performed with both hands.

[0050] When the housing 61 of the control unit 3 contacts the sealing portion 56 provided on the upper surface of the housing 51 of the battery 2C, the sealing portion 56 is sandwiched between the housing 51 of the battery 2C and the housing 61 of the control unit 3. Therefore, the sealing portion 56 is disposed between the housing 51 of the battery 2C and the housing 61 of the control unit 3. With the opening 55 of the housing 51 of the battery 2C and the opening 65 of the housing 61 of the control unit 3 facing each other, the opening 55 of the housing 51 of the battery 2C and the opening 65 of the housing 61 of the control unit 3 are disposed inside the sealing portion 56. The sealing portion 56 prevents water droplets, dust, etc. from entering the housing 51 from the opening 55 of the housing 51 of the battery 2C, and also prevents water droplets, dust, etc. from entering the housing 61 from the opening 65 of the housing 61 of the control unit 3. Thereby, it is possible to connect the connector 52 of the battery 2C and the connector 62 of the control unit 3 in a state where the airtightness inside the housing 51 of the battery 2C and the airtightness inside the housing 61 of the control unit 3 are ensured. Further, there is no need to install a waterproof connector between the housing 51 of the battery 2C and the housing 61 of the control unit 3, and the cost for installing the waterproof connector is not required.

[0051] The connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C may be connected. For example, when the electric device unit 1 includes the storage batteries 2A and 2C and the control unit 3, the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C are connected. The storage battery 2A may be an example of a third electric device adjacent to the second electric device. An example of a method for connecting the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C will be described. First, with the opening 15 of the housing 11 of the storage battery 2A and the opening 55 of the housing 51 of the storage battery 2C facing each other, the storage batteries 2A and 2C are installed so that the storage batteries 2A and 2C are adjacent to each other. The storage battery 2A may be placed on the storage battery 2C. With the opening 15 of the housing 11 of the storage battery 2A and the opening 55 of the housing 51 of the storage battery 2C facing each other, by moving the connector 12 of the storage battery 2A, the connector 12 of the storage battery 2A can be connected to the connector 52 of the storage battery 2C. Therefore, it is possible to easily connect the connectors to each other. For example, in a state where the lid portion 22 does not cover the hole portion 21 of the housing 11, the user puts a hand into the space where the connector 12 in the housing 11 is arranged through the hole portion 21 of the housing 11 and moves the connector 12 of the storage battery 2A to connect the connector 12 of the storage battery 2A to the connector 52 of the storage battery 2C.

[0052] The connector 12 of the storage battery 2A is arranged inside the housing 11 and does not protrude outside the housing 11. Therefore, when connecting the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C, the risk of damage to the connector 12 of the storage battery 2A is low. The connector 52 of the storage battery 2C is arranged inside the housing 51 and does not protrude outside the housing 51. Therefore, when connecting the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C, the risk of damage to the connector 52 of the storage battery 2C is low. The user can avoid a connection failure between the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C by visually checking the connection state between the connector 12 of the storage battery 2A and the connector 52 of the storage battery 2C through the hole portion 21 of the housing 11 of the storage battery 2A.

[0053] The connector 36 of the storage battery 2B and the connector 62 of the control unit 3 may be connected. For example, the electric When the air conditioning unit 1 includes the storage batteries 2B and 2C and the control unit 3, the connector 36 of the storage battery 2B and the connector 62 of the control unit 3 are connected. The method of connecting the connector 36 of the storage battery 2B and the connector 62 of the control unit 3 is the same as the method of connecting the connector 16 of the storage battery 2A and the connector 62 of the control unit 3.

[0054] A storage battery 2 having the same configuration as the storage battery 2A or 2B may be additionally provided between the storage battery 2A and the control unit 3.
