Abstract

A connecting device for detachably connecting electrical connections, for example between a rechargeable battery and an electrical power tool or a rechargeable battery and a charging device. The connecting device includes a carrier unit and at least one receptacle connectable to the carrier unit. A receptacle as part of and for connection to a connecting device. A carrier unit as part of a connecting device and for accommodating at least one receptacle.

First claim

The invention claimed is:

1. A connecting device for detachably connecting electrical connections, the connecting device comprising: a carrier unit; and at least one first receptacle connectable to the carrier unit; at least one second receptacle connectable to the carrier unit, the at least first and second receptacles being positioned consecutively in series along the carrier unit in such a way that a contact element is connected to the at least first and second receptacles when the contact element is connected to the connecting device; wherein each of the first and second receptacles includes a first end, a second end, a base element, a first wall element, a second wall element and a spring unit, including a first spring element and a second spring element, for accommodating and holding a contact element, the first spring element being connected to the first wall element, and the second spring element being connected to the second wall element; wherein the carrier unit includes a U profile having at least two holding elements for positioning and holding the first receptacle on the carrier unit.

2. The connecting device as recited in claim 1 wherein the first spring element and the second spring element extend from the first end of the receptacle between the first and second wall elements to the second end of the receptacle in a first direction.

3. The connecting device as recited in claim 1 wherein the first spring element and the second spring element extend from the second end of the receptacle in a first direction.

4. A rechargeable battery connecting device for detachably connecting a rechargeable battery and an electrical power tool or the rechargeable battery and a charging device, the rechargeable battery connecting device comprising the connecting device as recited in claim 1 .

5. A connecting device for detachably connecting electrical connections, the connecting device comprising: a carrier unit; and at least one first receptacle connectable to the carrier unit; at least one second receptacle connectable to the carrier unit, the at least first and second receptacles being positioned consecutively in series along the carrier unit in such a way that a contact element is connected to the at least first and second receptacles when the contact element is connected to the connecting device; wherein each of the first and second receptacles includes a first end, a second end, a base element, a first wall element, a second wall element and a spring unit, including a first spring element and a second spring element, for accommodating and holding a contact element, the first spring element being connected to the first wall element, and the second spring element being connected to the second wall element; wherein the base element of the first receptacle includes a convexity and an indentation, the convexity being situated opposite the indentation, and a design of the convexity corresponding to an indentation design of the indentation so that the convexity of the first receptacle is insertable into the indentation of a second receptacle.

6. A connecting device for detachably connecting electrical connections, the connecting device comprising: a carrier unit; and at least one first receptacle connectable to the carrier unit; at least one second receptacle connectable to the carrier unit, the at least first and second receptacles being positioned consecutively in series along the carrier unit in such a way that a contact element is connected to the at least first and second receptacles when the contact element is connected to the connecting device; wherein each of the first and second receptacles includes a first end, a second end, a base element, a first wall element, a second wall element and a spring unit, including a first spring element and a second spring element, for accommodating and holding a contact element, the first spring element being connected to the first wall element, and the second spring element being connected to the second wall element; wherein the carrier unit has a first side element and a second side element defining an elongated cavity to accommodate the at least one first receptacle and the at least one second receptacle, the first and second side elements having holding elements for positioning and holding the at least one first receptacle and the at least one second receptacle.

7. The connecting device as recited in claim 6 wherein the holding elements extend straight with respect to the first and second side elements.

8. The connecting device as recited in claim 6 wherein at least some of the holding elements are opposite to each other and toward each other.

9. The connecting device as recited in claim 6 wherein the at least one first receptacle and the at least one second receptacle each have a first elevation positioned on the first wall element and a second elevation positioned on the second wall element, the first and second elevations contacting the carrier unit.
