Die Patentanmeldung P 20556 Ib/87 a betrifft einen Elektroschraubenzieher, in dessen Hohlgriff axial hintereinander und kraftschlüssig nacheinander ein Elektromotor, ein Untersetzungsgetriebe, eine Rutschkupplung und ein Werkzeughalter sowie eine Batterie untergebracht sind, und ein in Ruhelage wirksames, mit einem Arbeitskontakt im Motorstromkreis gekuppeltes, durch einen Drücker auslösbares Gesperre zwischen Werkzeugträger und Rutschkupplung.The patent application P 20556 Ib / 87 a relates to one Electric screwdriver into its hollow handle axially one behind the other and frictionally one after the other Electric motor, a reduction gear, a slip clutch and a tool holder as well as a battery are housed, and an effective in the rest position, coupled with a make contact in the motor circuit, Lock that can be released by a lever between the tool carrier and the slip clutch.
Der Vorteil dieses Geräts ist seine Handlichkeit und Vielseitigkeit, welche durch den Fortfall der das Arbeiten behindernden Netzzuleitung und das griffbequehme verhältnismäßig dicke, den Batterieantrieb aufnehmende Gehäuse erreicht wird, wobei gleichzeitig der Batterieantrieb gegen Überlastung wirksam geschützt ist und seine Kapazität optimal ausgenutzt wird.The advantage of this device is its handiness and versatility, which is due to the elimination of the Work hindering power supply and the easy-to-grip, relatively thick, battery drive receiving housing is achieved, at the same time the battery drive is effective against overload is protected and its capacity is optimally used.
Nach der Erfindung wird die Handhabung des Elektroschraubenziehers noch weiter vereinfacht durch die Anwendung eines seiner gedrungenen Bauweise Rechnung tragenden und konstruktiv sehr einfachen, zusätzliche Teile vermeidenden Ladeanschlusses, welcher das Herausnehmen der Batterien zum Aufladen in an sich bekannter Weise vermeidet, wobei die massefreie Anschlußfeder für den Motor in einem Kontaktlappen ausläuft, der mit Zwischenlage eines Isolierringes unter einer Buchsenbohrung des an Masse liegenden, metallischen Gehäuses fest ist, derart, daß er mit diesem eine Koaxialbuchse bildet.According to the invention, the handling of the electric screwdriver is further simplified by the use of one of its compact design, which is structurally very simple, additional parts avoiding charging connector, which allows the batteries to be removed for charging avoids in a known manner, the floating connection spring for the motor in one Contact tab expires with the interposition of an insulating ring under a socket hole of the to ground lying, metallic housing is fixed in such a way that it forms a coaxial socket with this.
