Coupling head of a coupling device for mechanically connecting two units, in particular vehicle units

The coupling head (1) has a base body (2) at which coupling closures and/or electric contact couplers (12) are attached, where the closures produce mechanical connection with coupling closures of a counter coupling head. The base body is accommodated in a coupling head housing (3) together with the closures and the couplers. A coupling shaft (5) is pivotable in a horizontal and/or vertical plane and hinged at a hinge of the base body. A guiding body is made of electrically insulated material i.e. plastic, and a contact pin is made of electrically non-conductive material. An independent claim is also included for a coupling device comprising a coupling head.
