Abstract

A contact holder device for a hand-held power tool includes at least one main body that is disposed inside a housing unit of the hand-held power tool. The main body accommodates or fixes contact elements configured to transmit data signals and/or electrical energy. The main body has at least one disposition plane and at least one group of contact elements are disposed in the disposition plane. The main body has at least one further disposition plane and at least one further group of contact elements are disposed in the further disposition plane. The further disposition plane is disposed in an offset manner in relation to the disposition plane.

Claims

1. A contact holder device for a hand-held power tool, comprising:

at least one main body disposed inside a housing unit of the hand-held power tool, the main body one or more of accommodating and fixing contact elements configured to transmit data signals and/or electrical energy, the main body having at least one disposition plane with at least one group of contact elements disposed in the disposition plane,

wherein the main body has at least one further disposition plane with at least one further group of contact elements disposed in the further disposition plane, the further disposition plane disposed in an offset manner in relation to the disposition plane,

wherein the at least one group of contact elements and the at least one further group of contact elements are configured to contact counter-contact elements of an optional function module, which is configured, when in a coupled state, to provide an additional function that is not required for a fundamental function of the hand-held power tool.

3. The contact holder device according to claim 1, wherein the main body comprises one or more of:

individual accommodating chambers disposed in the disposition plane and configured to accommodate individual contact elements of the group of contact elements, and

further individual accommodating chambers disposed in the further disposition plane and configured to accommodate individual contact elements of the further group of contact elements.

6. The contact holder device according to claim 1, wherein the main body has at least one electronics accommodating region, and wherein at least one electronic unit is disposed in the electronics accommodating region.

8. The contact holder device according to claim 1, wherein the main body constitutes, at least partly, an insulator between the contact elements.

9. The contact holder device according to claim 1, further comprising at least one cooling unit disposed on the main body and configured to remove heat of the contact elements.

10. The contact holder device according to claim 6, wherein the electronic unit is one or more of a Bluetooth unit and an RFID unit.

2. A contact holder device for a hand-held power tool, comprising:

at least one main body disposed inside a housing unit of the hand-held power tool, the main body one or more of accommodating and fixing contact elements configured to transmit data signals and/or electrical energy, the main body having at least one disposition plane with at least one group of contact elements disposed in the disposition plane,

wherein the main body has at least one further disposition plane with at least one further group of contact elements disposed in the further disposition plane, the further disposition plane disposed in an offset manner in relation to the disposition plane,

wherein the disposition plane and the further disposition plane are parallel to and spaced apart from each other such that the disposition plane does not intersect any contact elements of the at least one further group of contact elements and the further disposition plane does not intersect any contact elements of the at least one group of contact elements, and

wherein the contact elements define a connection direction that is substantially parallel to the disposition and further disposition planes.

4. A contact holder device for a hand-held power tool, comprising:

at least one main body disposed inside a housing unit of the hand-held power tool, the main body one or more of accommodating and fixing contact elements configured to transmit data signals and/or electrical energy, the main body having at least one disposition plane with at least one group of contact elements disposed in the disposition plane,

wherein the main body has at least one further disposition plane with at least one further group of contact elements disposed in the further disposition plane, the further disposition plane disposed in an offset manner in relation to the disposition plane, and

wherein the main body has at least one accommodating region for one or more of a shielding element and a filter element configured to one or more of (i) shield individual contact elements of one or more of the group of contact elements and the further group of contact elements and (ii) filter data signals.

5. The contact holder device according to claim 4, wherein the accommodating region is disposed, at least partly, in the further disposition plane.

7. A contact holder device for a hand-held power tool, comprising:

at least one main body disposed inside a housing unit of the hand-held power tool, the main body one or more of accommodating and fixing contact elements configured to transmit data signals and/or electrical energy, the main body having at least one disposition plane with at least one group of contact elements disposed in the disposition plane,

wherein the main body has at least one further disposition plane with at least one further group of contact elements disposed in the further disposition plane, the further disposition plane disposed in an offset manner in relation to the disposition plane, and

wherein the main body comprises at least one electronics accommodating region that is disposed between the disposition plane and the further disposition plane as viewed along a direction that is at least substantially perpendicular to a connection direction of the contact elements.
