ABSTRACT:
An automatic electric cord rewinding apparatus with contacts for supplying electric power. The apparatus comprises a terminal body, a pair of bow-shaped contact terminals secured to an inner surface of the terminal body by a snap fit and spaced apart from each other, and a winding wheel provided with an opening adapted to receive and support the terminal body, a housing provided with a shaft and inserted into the winding wheel in order to support the winding wheel rotatably. The apparatus also includes an annular body inserted onto the shaft of the housing and divided into two parts by means of a partition member integrally formed with the annular body, and a pair of conduction rings inserted onto the parts of the annular body, respectively, thereby providing the contacts by contacting of said contact terminals with the conduction rings, respectively. The present invention provides an automatic electric cord rewinding apparatus with contacts in which the short between the polar charging parts of the annular body 28, which may occur due to the exchanging of the polar brass powder, can be efficiently prevented as a result of division of the annular body into the two polar parts.
