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).
A self-winding cable reel comprising a base plate which receives a cable drum on a bearing spindle, wherein a circumferential stub (3) 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 and a third circumferential wall, wherein a chamber of the base plate adjoins a window of the third circumferential wall and receives a winding spring (8) fastened to the circumferential stub, wherein the third circumferential wall has at least one further window, through-which a braking roller reaches and bears against an inner surface of the circumferential stub, wherein a central annular wall of the base plate receives contact rings and carries the bearing spindle and wherein an annular wall of the cable drum carries sliding contacts.
