Abstract

An electrical assembly is provided to a human-powered vehicle. The electrical assembly includes an electric component and an electrical cable. The electrical cable has a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable. A cable intersection is formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component.

First claim

What is claimed is:

1. An electrical assembly for a human-powered vehicle, the electrical assembly comprising:
an electric component; and
an electrical cable having a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable,
a cable intersection being formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component, the intermediate section of the electrical cable extending over and wrapping around itself to form the cable intersection.

2. The electrical assembly according to claim 1 , wherein
a portion of the intermediate section of the electrical cable at least partly extends in a direction away from the electric component.

3. The electrical assembly according to claim 1 , wherein
the electric component includes a housing having a first surface and a second surface located on the opposite side of the electric component with respect to the first surface.

4. The electrical assembly according to claim 3 , wherein
the first cable-end of the electrical cable enters the first surface of the housing,
the intermediate section of the electrical cable partly extends from the second surface in a direction away from the electric component, and
the cable intersection is formed on the first surface of the housing.

5. The electrical assembly according to claim 1 , wherein
the electric component includes an electric circuit board, and
the first cable-end of the electrical cable is electrically connected to the electric circuit board.

6. A hub assembly comprising the electrical assembly according to claim 1 , the hub assembly comprising:
a hub axle having a first axial end and a second axial end; and
a hub body rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly; wherein
the electric component is non-rotatably disposed on the hub axle.

7. The hub assembly according to claim 6 , further comprising
a guide portion, and
the guide portion is included in the hub axle.

8. The hub assembly according to claim 6 , wherein
the electric component includes a housing having a first surface facing the first axial end of the hub axle, a second surface facing the second axial end of the hub axle, and an opening extending from the first surface to the second surface, and
the hub axle extends through the opening of the electric component.

9. The hub assembly according to claim 6 , wherein
the hub axle includes a cable receiving passageway axially extending between the electric component and the second axial end of the hub axle, and
the intermediate section of the electrical cable is at least partly disposed in the cable receiving passageway.

10. The hub assembly according to claim 6 , wherein
the electric component includes an electric circuit board, and
the electric circuit board is disposed perpendicular to the rotational center axis.

11. The hub assembly according to claim 10 , further comprising
at least one capacitor electrically connected to the electric circuit board.

12. The hub assembly according to claim 6 , further comprising
an electric power generator provided to the hub body, and configured to generate electric power by rotation of the hub body.

13. The hub assembly according to claim 6 , further comprising
a sprocket support structure rotatably disposed around the rotational center axis to transmit a driving force to the hub body while rotating in a driving rotational direction around the rotational center axis.

14. The hub assembly according to claim 13 , further comprising
a detected part disposed on the sprocket support structure, and
a rotation detection sensor being configured to detect the detected part to detect rotation of the sprocket support structure around the rotational center axis.

15. An electrical assembly for a human-powered vehicle, the electrical assembly comprising
an electric component;
an electrical cable having a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable; and
a guide portion,
a cable intersection being formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component,
the intermediate section of the electrical cable being wound at least once around the guide portion to hold the intermediate section of the electrical cable against the guide portion.

16. The electrical assembly according to claim 15 , wherein
the intermediate section of the electrical cable includes a wound portion winding around the guide portion, a first intersecting portion and a second intersecting portion, the first intersecting portion extending over the second intersecting portion at an intersection point of the intermediate section of the electrical cable.

17. A hub assembly comprising:
an electric component;
an electrical cable having a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable,
a hub axle having a first axial end and a second axial end;
a hub body rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly;
a guide portion; and
a spacer provided between the hub axle and the electric component in a radial direction with respect to the rotational center axis,
a cable intersection being formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component,
the electric component being non-rotatably disposed on the hub axle, and
the guide portion being included in the spacer.

18. A hub assembly comprising:
an electric component;
an electrical cable having a first cable-end electrically connected to the electric component and a second cable-end spaced from the first cable-end by an intermediate section of the electrical cable,
a hub axle having a first axial end and a second axial end;
a hub body rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly;
a guide portion
a cable intersection being formed in the intermediate section of the electrical cable to restrict movement of the electrical cable relative to the electric component,
the electric component being non-rotatably disposed on the hub axle, and
the guide portion being included in the electric component.

19. The hub assembly according to claim 18 , wherein
the electric component includes a housing, and
the guide portion is included in the housing.
