Patent ID: 7785156

Claim:
An electrical connector for a dynamo hub, the dynamo hub including a hub axle that is formed with a groove extending along an axial direction, a stator unit that is retained on the hub axle and that has a conducting wire unit extending in the groove of the hub axle, and a rotor unit, said electrical connector comprising: a fastening component including a metallic surrounding wall adapted to be sleeved on the hub axle, and having an inner surface that is formed with a positioning protrusion to be inserted into the groove in the hub axle, an outer surface that is a non-circular surface, and a radial through hole extending from said inner surface to said outer surface and to be radially aligned with the groove in the hub axle, said radial through hole and said positioning protrusion being aligned in the axial direction; a hollow insulating component formed with a first accommodating space for non-rotatably retaining said fastening component therein, a second accommodating space, and a passage that is in spatial communication with said first and second accommodating spaces and that is radially aligned with said radial through hole; and an electrode unit including at least one electrode plate having a welding section disposed in said second accommodating space; whereby, the conducting wire unit of the stator unit of the dynamo hub is extendible in sequence through said radial through hole in said fastening component and said passage in said hollow insulating component to reach said second accommodating space for welding to said welding section of said at least one electrode plate of said electrode unit.
