A claw pole rotor comprises a shaft, first and second polar wheels fastened to the shaft, a winding provided with a winding insulator and surrounded by the first and second polar wheels, a commutator provided with at least one commutator ring, a fan fastened to the first polar wheel and disposed between the winding and the at least one commutator ring, at least one end-of-winding wire being linked to one of the at least one commutator rings, passing through a radial cavity provided between the fan and the first polar wheel. The winding insulator comprises a clip retaining the one end-of-winding wire. The retaining clip is fastened to the winding insulator and comprising crimping means intended to be disposed in the radial cavity to crimp the part of the end-of-winding wire extending into the radial cavity. |

1. Claw rotor (20) comprising:
a shaft (21); a first and a second magnet wheel (25, 26) which are secured on said shaft (21); a winding (17) which is provided with a coil insulator (27), and is surrounded by said first and second magnet wheels (25, 26); a collector which is provided with at least one collector ring (28, 29); a fan (31) which is secured on the first magnet wheel (25), and is disposed between the winding (17) and the at least one collector ring (28, 29); at least one end wire (15, 16) of the winding (17) being connected to one of said at least one collector rings (28, 29), and passing through a radial cavity (35, 36) provided between the fan (31) and the first magnet wheel (25); wherein the coil insulator comprises a clip (11) for securing one of said at least one end wires (15, 16) of the winding (17); said securing clip (11) being secured on said coil (17) insulator (27), and comprising crimping means (62, 63) which are designed to be disposed in the radial cavity, in order to crimp the part of the end wire (15, 16) of the winding which extends in said radial cavity; and in that said securing clip comprises means (57, 58) for support on the wall of the radial cavity, such that the crimping means clamp the end wire (15, 16) of the winding when the crimping means are disposed in said radial cavity. |
