The care unit according the present disclosure includes a care apparatus that includes a storage battery and a charging stand that is electrically connected to the care apparatus, and the care unit includes a first terminal, a second terminal, a third terminal, a fourth terminal, a first cover, a second cover, a third cover, and a fourth cover. When the care apparatus is held in a predetermined position of the charging stand, the third cover is not in contact with the first cover in a radial direction orthogonal to an insertion direction of the first cover, and the fourth cover is not in contact with the second cover in a radial direction orthogonal to an insertion direction of the second cover.
1. A care unit that includes a care apparatus and a charging stand, the care apparatus including a storage battery, the charging stand being electrically connected to the care apparatus, the care unit comprising:
a first terminal;
a second terminal;
a third terminal that is detachably connected to the first terminal;
a fourth terminal that is detachably connected to the second terminal;
a first cover having a cylindrical shape, the first cover including a first opening that allows insertion of the third terminal, and storing at least a part of the first terminal;
a second cover having a cylindrical shape, the second cover including a second opening that allows insertion of the fourth terminal, and storing at least a part of the second terminal;
a third cover having a cylindrical shape, the third cover including a third opening that allows insertion of the first cover, and storing at least a part of the third terminal; and
a fourth cover having a cylindrical shape, the fourth cover including a fourth opening that allows insertion of the second cover, and storing at least a part of the fourth terminal,
wherein when the care apparatus is held in a predetermined position of the charging stand, the third cover is not in contact with the first cover in a radial direction orthogonal to an insertion direction of the first cover, and the fourth cover is not in contact with the second cover in a radial direction orthogonal to an insertion direction of the second cover.
2. The care unit according to claim 1 , wherein
the first terminal is connected to the third terminal with a unidirectional biasing force only, and
the second terminal is connected to the fourth terminal with a unidirectional biasing force only.
3. The care unit according to claim 2 wherein an axis of a biasing direction of the first terminal is parallel to an axis of a biasing direction of the second terminal.
4. The care unit according to claim 1 , wherein two adjacent sides of each of a bounding rectangle of the first opening and a bounding rectangle of the second opening are different in length.
5. The care unit according to claim 1 , wherein the charging stand includes a guide that holds the care apparatus in a predetermined position.
6. The care unit according to claim 5 , wherein the guide includes a rotation regulating portion that regulates displacement of the care apparatus with respect to the charging stand in a rotation direction.
