Vehicle generator with short-circuit damage prevention

Claim 2

A vehicle generator comprising: a rotor core; a coil bobbin packaged within said rotor core; a rotor coil wound around said coil bobbin for permitting a direct current to flow therethrough; a stator; a stator coil wound around said stator; brushes; slip rings in contact with said brushes for permitting the direct current to flow; a rectifier for rectifying an alternating current generated; and a regulator set to force a direct current yielded as a result of said rectification to flow to a battery when said battery is charged to less than its prescribed capacity, while being set to force said direct current to ground when said battery is charged to or beyond its prescribed capacity; said rotor coil being wound around said coil bobbin such that an initial winding end of said rotor coil is connected with said regulator while a final winding end of said rotor coil is connected directly with said battery.

Claim 3

A vehicle generator comprising: a rotor core (3); a coil bobbin (4) packaged within said rotor core (3); a rotor coil (5) wound around said coil bobbin (4); first and second tie parts (4b, 4a ) formed on the edge of said coil bobbin (4), initial and final winding ends of said rotor coil (5) being connected respectively to said first and second tie parts; a stator; a stator coil (6a) wound around said stator; a ring assembly (11), comprising a pair of slip rings (8, 8a), pushed into said rotor core (3); a rectifier for rectifying an alternating current generated; a regulator (10) set to force a direct current yielded as a result of said rectification to flow to a battery (B) when said battery (B) is charged to less than its prescribed capacity; a first brush (7x) in contact with one of said slip rings (8a) and connected to said regulator (10); a second brush (7y) in contact with the other of said slip rings (8) and connected to said battery (B); two differently shaped lug ends (12a, 13a) formed on said slip ring assembly (11) and connected respectively to said slip rings (8, 8a); the shape of one lug end (13a) connected to said regulator (10) being distinguishably formed to correspond to said shape of said first tie part (4b) connected to the initial winding end of said rotor coil (5), and the shape of the other lug end (12a) connected to said battery (B) being distinguishably formed to correspond to the shape of said second tie part (4a ) connected to the final winding end of said rotor coil (5), such that the initial winding end of said rotor coil (5) is connected with the regulator (10) via said first tie part (4b) and said one lug end (13a), while the final winding end of said rotor coil (5) is connected directly with said battery (B) via said second tie part (4a ) and said other lug end (12a).

Claim 4

A vehicle generator comprising: a rotor core (3); a coil bobbin (4) packaged within said rotor core (3); a rotor coil (5) wound around said coil bobbin (4); first and second tie parts (4b, 4a ) formed on the edge of said coil bobbin (4), initial and final winding ends of said rotor coil (5) being connected respectively to said first and second tie parts; a stator; a stator coil (6a) wound around said stator; a ring assembly (11), comprising a pair of slip rings (8, 8a), pushed into said rotor core (3); a rectifier for rectifying an alternating current generated; a regulator (10) set to force a direct current yielded as a result of said rectification to flow to a battery (B) when said battery (B) is charged to less than its prescribed capacity; a first brush (7x) in contact with one of said slip rings (8a) and connected to said regulator (10); a second brush (7y) in contact with the other of said slip rings (8) and connected to said battery (B); two differently shaped lug ends (12a, 13a) formed on said slip ring assembly (11) and connected respectively to said slip rings (8, 8a); the shape of one lug end (13a) connected to said regulator (10) being distinguishably formed to correspond to said shape of said first tie part (4b) connected to the initial winding end of said rotor coil (5), and the shape of the other lug end (12a) connected to said battery (B) being distinguishably formed to correspond to the shape of said second tie part (4a ) connected to the final winding end of said rotor coil (5), such that the initial winding end of said rotor coil (5) is connected with the regulator (10) via said first tie part (4b) and said one lug end (13a), while the final winding end of said rotor coil (5) is connected directly with said battery (B) via said second tie part (4a ) and said other lug end (12a).

Claim 5

A vehicle generator as claimed in claim 2, wherein said first tie part (4b) and said one lug end (13a) are shaped as a "-", while said second tie part (4a ) and said other lug end (12a) are shaped as a "+".
