An improved structure of a wire winding box comprises a housing, a first communication cable, a second communication cable, a spiral spring, a first conductive disk, and a second conductive disk. The first conductive disk is installed with an inner and outer rings. A spiral spring is received within the outer ring, and the second communication cable winds the outer portion of the outer ring. A linear groove and a matched positioning block are installed within the inner ring. Two sides of the linear groove are alternatively extended with a plurality of cambered groove with unequal diameters so that one end thereof may receive each conductive piece at the respective position in the two sides of the positioning block so as to retain an electric contact with the conductive ring on the second conductive disk. By the aforementioned structure, the width and volume can be reduced effectively and a beautiful outlook is retained so that the present invention can be widely used in a mobile phone, a wireless phone, a phone without holding receiver, and other communication devices for increasing the convenience thereof.
