Abstract
A self-winding cable reel having a base plate which receives the cable drum on a bearing spindle. The technical problem is a stable and concentrated construction of all the functional parts on a base plate and a contact arrangement comprising a small number of individual parts. A circumferential stub (39) of the cable drum (3) projects into a U-shaped channel of the base plate (1), said channel being formed by a second circumferential wall (19), a second annular wall (20) and a third circumferential wall (21), a chamber (6) of the base plate (1) adjoins a window (26) of the third circumferential wall (21) and receives a winding spring (8) fastened to the circumferential stub (39), the third circumferential wall (21) has at least one further window (28), through which a braking roller (11) reaches and bears against the inner surface of the circumferential stub (39), a central annular wall (22) of the base plate (1) receives contact rings (12, 13) and carries the bearing-spindle (2), and an annular wall (40) of the cable drum (3) carries sliding contacts (14, 15).
