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 dust collection unit, which dust collection unit can be releasably fitted to the tool, comprising:
- a power supply circuit located in 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 dust collection unit, for electrically connecting the power supply circuit in the tool to the motor (51) of the dust collection 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 dust collection unit, anda second mechanical fixing arrangement, located remotely from the first mechanical fixing arrangement 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 dust collection 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 tool having a dust collection unit powered by a motor, which unit can be releasably fitted to the tool includes a plug arrangement and a cooperating socket arrangement, one of which is formed on the tool and the other of which is formed on the unit. A first mechanical fixing arrangement is provided comprising a first projection and a first cooperating recess, one of which is formed on the tool and the other of which is formed on the unit. A second mechanical fixing arrangement is provided and comprises a manually actuable releasable latch arrangement and a second cooperating recess, 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.
