Abstract

A hand tool device having at least one charging coil, which includes at least one coil core which is at least partially made of a ceramic material and which is provided for transmitting energy. The coil core may be configured as a composite component.

Claims

1. A hand tool device, comprising:

at least one charging coil which includes at least one coil core which is at least partially made of a ceramic material and which is provided for transmitting energy;

wherein the coil core is configured as a composite component.

2. The hand tool device of claim 1, wherein the coil core has at least one magnetic field bundling element which is made of a ceramic material.

3. The hand tool device of claim 1, wherein the coil core has an at least largely toroid design.

4. The hand tool device of claim 1, wherein the coil core has at least one magnetic field bundling element which has an at least largely toroid design.

5. The hand tool device of claim 1, wherein the coil core is at least partially formed by a film.

6. The hand tool device of claim 5, wherein the film forms at least one part of a surface of the coil core.

7. The hand tool device of claim 1, wherein the coil core is at least partially made of a soft elastic material.

8. A hand tool battery, comprising:

a hand tool device, including;

at least one charging coil which includes at least one coil core which is at least partially made of a ceramic material and which is provided for transmitting energy;

wherein the coil core is configured as a composite component.

9. A charging device, comprising:

a hand tool device, including;

at least one charging coil which includes at least one coil core which is at least partially made of a ceramic material and which is provided for transmitting energy;
