The 1 st connector 200 has a 1 st terminal 222a, a 2 nd terminal 222b, a 3 rd terminal 222c, a 1 st regulator 224a, and a 2 nd regulator 224b. The 1 st terminal 222a, the 2 nd terminal 222b, the 3 rd terminal 222c, the 1 st regulator 224a, and the 2 nd regulator 224b are exposed from the housing 110.
The 1 st terminal 222a is one of a power supply terminal and a ground terminal, the 2 nd terminal 222b is the other of the power supply terminal and the ground terminal, and the 3 rd terminal 222c is a sense terminal. In the example shown in fig. 1 and 2, the 1 st terminal 222a and the 2 nd terminal 222b are separated from each other with the 3 rd terminal 222c interposed therebetween. Therefore, the insulation/voltage resistance between the 1 st terminal 222a and the 2 nd terminal 222b can be ensured.
The 1 st regulator 224a and the 2 nd regulator 224b are separated from each other with the 1 st terminal 222a, the 2 nd terminal 222b, and the 3 rd terminal 222c interposed therebetween. The 1 st regulator 224a is located beside the 1 st terminal 222 a. The 2 nd regulator 224b is located beside the 2 nd terminal 222 b.
The battery module 12 will be described in detail with reference to fig. 3.
The battery module 12 includes a plurality of battery cells 100, a circuit board 140, a bracket 142, a wiring 144, and a 1 st connector 200.
The plurality of battery cells 100 are mounted on the circuit board 140 via the bracket 142. Each battery cell 100 is electrically connected to the circuit board 140 via a wiring 144. The circuit substrate 140 is a Battery Management Unit (BMU) in the example shown in fig. 3.
The 1 st connector 200 is mounted on the circuit board 140. The 1 st connector 200 is electrically connected to each battery cell 100 via the circuit board 140 and the wiring 144. Therefore, the electric power generated by each battery cell 100 can be supplied to the 1 st connector 200 via the wiring 144 and the circuit substrate 140.
The details of the holder 20 will be described with reference to fig. 4.

According to the above structure, the cost of the base 310 can be reduced. In particular, in the above-described structure, it is not necessary to provide a member for connecting the l base 312 and the 2 nd base 314 to each other. Therefore, the cost of the base 310 can be reduced by the amount of the member.
With the above configuration, the base 310 can be reduced in weight. Specifically, in the above-described structure, it is not necessary to provide a member for connecting the 1 st base 312 and the 2 nd base 314 to each other. Therefore, the base 310 can be reduced in weight by the amount of the member. The light weight of the base 310 is particularly suitable for a case where an object (for example, an unmanned aerial vehicle) to which the base 310 is attached is required to be light.
With the above configuration, the degree of freedom of the size of the battery pack 10 (fig. 1 and 2) that can be held by the holder 20 can be increased. Specifically, in the above-described configuration, the distance between the 1 st base 312 and the 2 nd base 314 can be adjusted according to the size of the battery pack 10 (fig. 1 and 2). Therefore, by adjusting the distance between the 1 st base 312 and the 2 nd base 314, the degree of freedom of the size of the battery pack 10 (fig. 1 and 2) that can be held by the holder 20 can be increased.
The 1 st base 312 has a surface 312a, a surface 312b, and a surface 312c. The faces 312a and 312b are opposed to each other. The surface 312c is located between the surfaces 312a and 312b and faces the No. 2 base 314.

The 1 st guide paths 322 are provided in the 1 st base 312. The plurality of 1 st guide paths 322 include a 1 st guide path 322a and a 1 st guide path 322b. The 1 st guide path 322a is provided on the surface 312a of the 1 st base 312. The 1 st guide path 322b is provided on the surface 312b of the 1 st base 312. In the example shown in fig. 4, the 1 st guide path 322a is a convex portion formed on the surface 312a, and the 1 st guide path 322b is a convex portion formed on the surface 312 b.
The plurality of 2 nd guide paths 324 are provided in the 2 nd susceptor 314. The plurality of 2 nd guide paths 324 include a 2 nd guide path 324a and a 2 nd guide path 324b. The 2 nd guide path 324a is provided on the surface 314a of the 2 nd base 314. The 2 nd guide path 324b is provided on the surface 314b of the 2 nd base 314. In the example shown in fig. 4, the 2 nd guide path 324a is a convex portion formed on the surface 314a, and the 2 nd guide path 324b is a convex portion formed on the surface 314 b.
The 2 nd engaging portion 330 is provided on the surface 314c of the 2 nd base 314. In the example shown in fig. 4, the 2 nd engaging portion 330 is an opening formed in the face 314c of the 2 nd base 314.
The battery system 30 will be described in detail with reference to fig. 5 and 6.
In the example shown in fig. 5 and 6, the battery pack 10 is mounted on the holder 20 in the Z direction and is movable relative to the holder 20 in the X direction.
The 1 st base 312 and the 2 nd base 314 are arranged in one direction (X direction in fig. 5 and 6). The 1 st sliding portion 122a, the 1 st sliding portion 122b, the 2 nd sliding portion 124a, and the 2 nd sliding portion 124b (fig. 2) are slidable along the 1 st guide path 322a, the 1 st guide path 322b, the 2 nd guide path 324a, and the 2 nd guide path 324b (fig. 4), respectively, so that the battery pack 10 is movable relative to the holding body 20 along the above-described one direction (the X direction in fig. 5 and 6). Therefore, the battery pack 10 can be easily moved with respect to the holder 20 so that the 1 st side surface 110c1 of the case 110 faces the 2 nd connector 400.
In the present embodiment, the 1 st sliding portion 122a, the 1 st sliding portion 122b, the 2 nd sliding portion 124a, and the 2 nd sliding portion 124b are each concave portions, and the 1 st guide path 322a, the 1 st guide path 322b, the 2 nd guide path 324a, and the 2 nd guide path 324b are each convex portions that can be fitted to the 1 st sliding portion 122b, the 2 nd sliding portion 124a, and the 2 nd sliding portion 124b, respectively. In another example, the 1 st sliding portion 122a, the 1 st sliding portion 122b, the 2 nd sliding portion 124a, and the 2 nd sliding portion 124b may be each a convex portion, and the 1 st guide path 322a, the 1 st guide path 322b, the 2 nd guide path 324a, and the 2 nd guide path 324b may be each a concave portion that is fittable to the 1 st sliding portion 122b, the 2 nd sliding portion 124a, and the 2 nd sliding portion 124b, respectively.
In the present embodiment, the 1 st sliding portion 122b and the 2 nd sliding portion 124b cannot be fitted to the 1 st guide path 322a and the 2 nd guide path 324a, and the 1 st sliding portion 122a and the 2 nd sliding portion 124a cannot be fitted to the 1 st guide path 322b and the 2 nd guide path 324b. For example, in the example shown in fig. 5, the width of the 1 st guide route 322a and the width of the 1 st guide route 322b can be made different from each other, and the width of the 2 nd guide route 324a and the width of the 2 nd guide route 324b can be made different from each other in the Z direction. In this case, the battery pack 10 can be prevented from being mounted to the holder 20 in the wrong direction, that is, the 2 nd side surface 110c2 of the case 110 can be prevented from facing the 2 nd connector 400 by mounting the battery pack 10 to the holder 20.
When the battery pack 10 is held by the holder 20, the 1 st terminal 222a, the 2 nd terminal 222b, and the 3 rd terminal 222c of the battery pack 10 are connected to the 1 st terminal 422a, the 2 nd terminal 422b, and the 3 rd terminal 422c of the holder 20, respectively.

The outline of the 2 nd connector 400 will be described with reference to fig. 10 and 11. In the example shown in fig. 10 and 11, the 2 nd connector 400 is a floating connector. The base 310 has a shaft member 350. The shaft member 350 passes through the opening 450 of the substrate 410 in one direction (the Z direction of fig. 10 and 11). The substrate 410 is movable relative to the shaft member 350 along the one direction (Z direction in fig. 10 and 11) and a direction intersecting the one direction (Y direction in fig. 10 and 11). Therefore, the 2 nd connector 400 is movable in two directions (the Y direction and the Z direction in fig. 10 and 11) with respect to the base 310.
The direction in which the 2 nd connector 400 is movable with respect to the base 310 is not limited to the second direction, and may be three directions (for example, the X direction, the Y direction, and the Z direction in fig. 5 and 6), or may be only one direction (for example, any one of the Y direction and the Z direction in fig. 10 and 11).
The base 310 and the 2 nd connector 400 will be described in detail with reference to fig. 9.
The substrate 410 of the 2 nd connector 400 is fixed to the base 310 (the 1 st base 312) by a plurality of fixtures 550. The plurality of fixtures 550 includes a fixture 550a, a fixture 550b, a fixture 550c, and a fixture 550d.

The base 310 and the 2 nd connector 400 will be described in detail with reference to fig. 10 and 11.
The base 310 has a plurality of shaft members 350. The plurality of shaft members 350 include a shaft member 350a, a shaft member 350b, a shaft member 350c, and a shaft member 350d. The shaft members 350a, 350b, 350c, and 350d pass through the openings 450a, 450b, 450c, and 450d of the substrate 410 in one direction (Z direction in fig. 10 and 11), respectively.
The shaft members 350a, 350b, 350c, and 350d are respectively provided with a fixture 550a, 550b, 550c, and 550d from the 2 nd surface 414 side toward the 1 st surface 412 side of the substrate 410. Therefore, the 2 nd connector 400 (substrate 410) is fixed to the base 310 (1 st base 312) from the 2 nd surface 414 side toward the 1 st surface 412 side of the substrate 410.
In the present embodiment, each fixture 550 is a screw. In other examples, the fixture 550 may be a member other than a screw.
In the example shown in fig. 10 and 11, the width of the opening 450a, the width of the opening 450b, the width of the opening 450c, and the width of the opening 450d are respectively wider than the width of the shaft member 350a, the width of the shaft member 350b, the width of the shaft member 350c, and the width of the shaft member 350d. Therefore, the substrate 410 is movable relative to the base 310 along the axial direction (Z direction) of each shaft member 350, and is movable relative to the base 310 along the direction (Y direction) that is the axial direction of the shaft member 350.
In the example shown in fig. 10 and 11, the set of the shaft members 350a and 350c and the set of the shaft members 350b and 350d are located on opposite sides of the terminal block 420. Therefore, the 2 nd connector 400 can be stably mounted on the base 310 (the 1 st base 312).
Details of the shaft member 350 will be described with reference to fig. 12.
The base 310 has a stop 352 and the fixture 550 has a stop 552. The stopper 352 of the base 310 and the stopper 552 of the fixture 550 are opposite to each other. The shaft member 350 is located between the stopper 352 of the base 310 and the stopper 552 of the fixture 550. The substrate 410 is mounted on the shaft member 350 such that a portion of the 1 st surface 412 is opposed to the stopper 352 of the base 310 and a portion of the 2 nd surface 414 is opposed to the stopper 552 of the fixture 550. In the example shown in fig. 12, the movable range of the substrate 410 in the Z direction can be limited by the stopper 352 of the base 310 and the stopper 552 of the fixture 550.
The embodiments of the present invention have been described above with reference to the drawings, but these are examples of the present invention and various configurations other than the above-described configurations can be adopted.
