ABSTRACT:
The present disclosure is related to a universal joint adapted mainly for connecting a telephone receiver to an extension cord thereby the phone user can move along with the receiver at the extension cord's length without getting the extension cord twisted or tangled. The universal joint has a dome-shaped cap which is provided with an opening on the wall thereof and a peripheral flange disposed at the bottom thereof; and a tapered cord seat removably inserted in the opening has a number of obliquely extended resilient legs which are bent to form a number of contact protrusions at the bottom thereof; and a pc board having a number of concentric contact tracks in contact with the contact protrusions of the cord seat; and a bottom base having a concave into which the pc board and the dome-shaped cap with the cord seat attached thereto are located; and a horizontal rectangular extension projected from the bottom base and having a downwardly extended engagement chip is coupled to a phone receiver; thereby the extension cord engaged with the cord seat at one end can be freely rotated without being tangled with the help of the rotatable dome-shaped cap.
