Abstract
A hand machine tool with a battery operated drive motor has a plug coupling for electrical contacting of the drive motor with the battery unit mounted on the hand machine tool. The coupling includes a base provided at the machine side and displaceable relative to a machine housing. The base has contact springs which are in contact with contact surfaces provided on a plug housing of the battery unit. A centering element is located between the base and the plug housing and provides a fitting abutment between the contact springs and the contact surfaces.
