Hand held drilling and/or hammering tool with dust collection unit
First Claim
1. An electrically powered hand held drilling and/or hammering tool having a dust collection unit powered by a motor (51) housed in the unit, which unit can be releasably fitted to the tool, comprising;
- a plug arrangement (12) and a cooperating socket arrangement (28), one of which is formed on the tool and the other of which is formed on the unit, for electrically connecting the power supply for the tool to the motor (51) of the unit;
a first mechanical fixing arrangement comprising a first projection (8) and a first cooperating recess (54), one of which is formed on the tool and the other of which is formed on the unit, located adjacent the respective part of the plug and socket arrangements; and
a second mechanical fixing arrangement, located remotely from the first and comprising a manually actuable releasable fixing arrangement (72,66) and a second cooperating recess (60), one of which is formed on the tool and the other of which is formed on the unit, wherein the first and second mechanical fixing arrangements cooperate to secure the dust collection unit to the tool in such a way that the plug and socket arrangements form an electrical connection.

Abstract
An electrically powered hand held drilling and/or hammering tool having a dust collection unit powered by a motor (51) housed in the unit, which unit can be releasably fitted to the tool. A plug arrangement (12) and a cooperating socket arrangement (28), one of which is formed on the tool and the other of which is formed on the unit, are provided for electrically connecting the power supply for the tool to the motor (51) of the unit. A first mechanical fixing arrangement is provided comprising a first projection (8) and a first cooperating recess (54), one of which is formed on the tool and the other of which is formed on the unit, located adjacent the respective part of the plug and socket arrangements and a second mechanical fixing arrangement is provided, located remotely from the first and comprising a manually actuable releasable latch arrangement (72,66) and a second cooperating recess (60), one of which is formed on the tool and the other of which is formed on the unit. The first and second mechanical fixing arrangements cooperate to secure the dust collection unit to the tool in such a way that the plug and socket arrangements form an electrical connection.
