A connector arrangement for an a-c. clock mechanism which includes a drive coil and drive train mounted in a housing formed of a plastic base plate and plastic cover member of shallow cup shape. The drive coil has a core and bobbin, the bobbin being secured by embossments in the housing so that the rear end thereof is spaced from the adjacent side wall to form a wide access space. A pair of vertically spaced axially extending prongs mounted on the edge of the bobbin and electrically connected to the drive coil project into the access space. An access opening in the adjacent side wall of the housing alined with the prongs on the bobbin provides entry into the access space. The access opening is of arbitrary cross sectional shape and small enough to preclude entry of a connector of conventional design. For supplying current to the drive coil the a-c. line cord has a connector with a tip portion cross sectionally fitted for snug reception in the access opening as well as a handle portion alined therewith. The tip portion of the connector has female electrical connections for engaging the prongs while the handle portion of the connector, which extends outside of the housing, includes a voltage dropping resistor, the heat of which is dissipated to the ambient atmosphere.
