Abstract

An electrical hand-held power tool includes a driving element (9; 9′) displaceable in the tool housing (8) along a drive axis (A) for driving a working tool (7, 7′), and at least one rigid electrical module located in the housing (8), and secured therein by at least one spring (4) that preloads the electrical module against the housing (8).

Claims

1. An electrical hand-held power tool, comprising a housing (8);

driving means (9;

9′

) displaceable in the housing (8) along a drive axis (A) for driving a working tool (7, 7′

);

at least one rigid electrical module located in the housing (8); and

at least one spring (4) for securing the electric module in the housing (8) and for preloading same against the housing (8).

2. An electrical hand-held power tool according to claim 1, wherein an oscillation axis (S) which is defined by a tensioning direction of the at least one spring (4), forms, with the drive axis (A), an angle of at least 30°

.

3. An electrical hand-held power tool according to claim 1, comprising two springs (4) provided on opposite sides of the electrical module for securing the same to the housing (8) and for preloading the electrical module against the housing (8).

4. An electrical hand-held power tool according to claim 1, wherein the electrical module is formed as a motor electronics module (6).

5. An electrical hand-held power tool according to claim 1, wherein the electrical module is formed as an accumulator module (6).

6. An electrical hand-held power tool according to claim 1, wherein the electrical module is connected with a highly flexible conducting strip (5).

7. An electrical hand-held power tool according to claim 1, wherein the electrical module is connected with a slidable current collector (12).
