Embodiment Construction

[0022] figure 1 A tool 1 with an insulation system 2 is shown. The tool 1 may be a screwing tool, a drilling tool, a riveting tool, a stamping tool, a bolt fastening tool, and the like. figure 1 Tool 1 in is a hand-held tool. But Tool 1 is not limited to this. The tool 1 can also be a stationary tool or a standing tool.

[0023] exist figure 1 The tool 1 has a handle 11 , an on-off switch 12 , a battery box 13 , a housing 14 and a driven unit 15 . The insulation system 2 has a first element 21 , a second element 22 , a receiving element 23 and a fastening unit 24 .

[0024] A battery such as, for example, a rechargeable accumulator or a non-rechargeable battery can be accommodated in the battery compartment 13 . The tool 1 is thus a cordless tool. Housing 14 is made of an electrically insulating material such as plastic. The tool 1 thus has a surface formed of an electrically insulating material in the region of the housing 14 . However, the tool 1 has a metal housing...

Abstract

The invention relates to an insulation system (2) for a tool (1), a tool (1) and a method for mounting the insulation system (2) for a tool (1) on a tool (1). The insulation system (2) comprises a first element (21) for electrically insulating a driven unit (15) of the tool (1) relative to a detachably fixed tool element of the tool (1) for machining a workpiece ) and a second element (22) for electrically insulating the driven unit (15) from the outside.

Description

technical field [0001] The invention relates to an insulation system for a tool, a tool and a method for mounting the insulation system on a tool. The tool is in particular a screwing / drilling tool which can be held in the user's hand. Background technique [0002] In the field of the automotive industry, tools such as tightening tools are used, for example, when installing the battery of an electric vehicle. The battery is usually an accumulator consisting of a plurality of elements which are screwed to each other. Here too, the screw is screwed onto the electrically conductive part. In this way it is ensured that the operator of the tool is protected from voltages which are dangerous to the operator. [0003] This is currently done, for example, by means of an insulating tape winding of the tool. But this is very expensive and prone to failure. In addition, contact with electrically conductive parts can only be avoided by this. But at least it does not prevent the vo...
