Charger and charging system
A pedestal type device that functions as anon-limiting example charger comprises a connection portion that is constituted by a connection plug and a cover. The cover is supported so as to be movable up and down through a second hole of a placement portion. Furthermore, a convex portion that is protruded toward a front side is provided in a center of a lower end portion of a rear support portion. Two first projections are formed on an upper surface of the cover, and a first hole is formed between them. The connection plug is supported so as to be movable up and down through a third hole. If the convex portion is fitted into a first concave portion formed in a rear surface of electronic device when the electronic device is placed on the placement portion, the first projections are respectively fitted into two third concave portions formed on an undersurface of the electronic device, whereby the cover is pushed down. Therefore, the connection plug is inserted into the depths of a connector of the electronic device.
1. A charger that charges an electronic device that includes a first electrical connector with a first electrical contact, a first fitting portion on a first surface, the first fitting portion being concave, and a second fitting portion on a second surface that is different from the first surface, the second fitting portion being concave, the charger comprising:
a placement portion configured to receive the electronic device;
a third fitting portion that is convex to extend into the first fitting portion when the placement portion receives the electronic device;
a fourth fitting portion that is convex to extend into the second fitting portion when the placement portion receives the electronic device; and
a second electrical connector with a second electrical contact configured to be electrically connected to the first electrical contact in conjunction with the fourth fitting portion extending into the second fitting portion, wherein
the third fitting portion and the fourth fitting portion are within the placement portion,
the placement portion is configured to receive the electronic device in a linear direction,
the fourth fitting portion is movable parallel to the linear direction,
the third fitting portion and the fourth fitting portion are not electrical contacts, and
the fourth fitting portion is movable independently of the second electrical connector.
2. The charger according to claim 1 , wherein the first surface intersects the second surface orthogonally or substantially orthogonally.
3. The charger according to claim 1 , wherein the third fitting portion functions as a first positioning member that determines a position of the electronic device to the placement portion, and the fourth fitting portion functions as a second positioning member that determines a position of the first electrical connector to the second electrical connector.
4. The charger according to claim 1 , wherein a fitting precision of the third fitting portion and the first fitting portion is lower than a fitting precision of the second fitting portion and the fourth fitting portion.
5. The charger according to claim 1 , wherein the third fitting portion is configured to extend into the first fitting portion prior to the fourth fitting portion extending into the second fitting portion when the placement portion receives the electronic device.
6. The charger according to claim 1 , wherein the fourth fitting portion is movable perpendicular to the linear direction.
7. The charger according to claim 1 , further comprising an elastic body that is disposed between the fourth fitting portion and a main body of the charger.
8. The charger according to claim 1 , wherein the second electrical connector is disposed between two fourth fitting portions.
9. The charger according to claim 1 , further comprising a movable member that surrounds at least the second electrical connector, and that is configured to move in the linear direction.
10. The charger according to claim 9 , wherein the fourth fitting portion is on a surface of the movable member.
11. The charger according to claim 10 , wherein the fourth fitting portion includes a projection having an inclined surface that is inclined to the linear direction.
12. The charger according to claim 10 , wherein the fourth fitting portion includes a projection in a shape of a cone or a truncated cone.
13. The charger according to claim 9 , further comprising a first support member that supports the second electrical connector movably in a second direction perpendicular to the linear direction; and a second support member that is different from the first support member, and supports the movable member movably in at least the second direction, wherein
when the second fitting portion extends into the fourth fitting portion, the second electrical connector is moved in the second direction as the movable member is moved in the second direction.
14. The charger according to claim 13 wherein each of the first support member and the second support member includes an elastic body.
15. The charger according to claim 1 , wherein when the placement portion receives the electronic device, the fourth fitting portion is movable independently of the second electrical connector parallel to the linear direction and the second electrical connector prevents movement of the fourth fitting portion perpendicular to the linear direction.
16. A charger that charges an electronic device that has a first fitting portion, the first fitting portion being concave, and a first electrical connector with a first electrical contact, the charger comprising:
a placement portion configured to receive the electronic device in a linear direction;
a second fitting portion that is convex to extend into the first fitting portion when the placement portion receives the electronic device, wherein the second fitting portion is not an electrical contact;
a second electrical connector with a second electrical contact configured to be electrically connected to the first electrical contact; and
a movable member that is movable parallel to the linear direction, the second fitting portion being positioned on the movable member such that the movable member is movable in conjunction with the second fitting portion extending into the first fitting portion when the placement portion receives the electronic device, and the movable member surrounding the second electrical connector,
wherein the movable member is movable independently of the second electrical connector.
17. A charging system comprising an electronic device and a charger that charges the electronic device, wherein
the electronic device comprises
