Abstract

A connection device for electrically connecting a plurality of first electrical components to a second electrical component and for arrangement on a first housing of the second component. In the interior at least one first and one second potential connection are arranged. The connection device includes a connection strip, which on a first side has a plurality of electrical plug-in connection units for respective electrical connection of one of the first components by a respective plug-in connection and a second opposite side relative to a first direction, for arrangement on a first component, a contacting unit which has a carrier for arrangement on a through opening of the first housing and at least one contact pair arranged on the carrier for electrically contacting the first and second potential connection.

First claim

1 . A connection device for electrically connecting multiple first electrical components to a second electrical component of a motor vehicle and for arrangement on a first housing of the second component, wherein at least one first and one second potential connection are arranged inside the housing,
the connection device comprising:
a connection strip which has a first side and a second opposite side relative to a first direction for arrangement on a first component, wherein the first side has multiple electrical plug-in connection units for the respective electrical connection of one of the multiple first electrical components by means of a respective plug-in connection;
a contacting unit, which has a carrier for arrangement at a through opening of the first housing and at least one contact pair arranged on the carrier with a first contact element for electrically contacting the first potential connection and a second contact element for electrically contacting the second potential connection; and
an electrical line arrangement, by which the multiple plug-in connection units are electrically conductively connected to the at least one contact pair.

2 . The connection device according to claim 1 , wherein the line arrangement has a first bus line which is electrically conductively connected to the first contact element and has a second bus line which is electrically conductively connected to the second contact element, wherein the multiple plug-in connection units comprise a first plug-in connection unit and a second plug-in connection unit, which respectively have a first connection contact which is electrically conductively connected to the first bus line, and a second connection contact which is electrically conductively connected to the second bus line.

3 . The connection device according to claim 1 , wherein the contacting unit has multiple contact pairs arranged on the same side of the carrier.

4 . The connection device according to claim 1 , wherein the carrier of the contacting unit is arranged on the second side of the connection strip.

5 . The connection device according to claim 1 , wherein the contacting unit is designed to be spatially separated from the connection strip, and the line arrangement has a connecting portion via which the contacting unit and the connection strip are connected.

6 . The connection device according to claim 1 , wherein the connecting portion of the line arrangement is designed to be flexible.

7 . A connection arrangement with a connection device according to claim 1 , wherein the connection arrangement has the first housing of the second component, in particular of the energy storage or of an electronic unit associated with the energy storage, wherein the carrier is arranged at the through opening of the first housing, so that the at least one contact pair projects into an interior of the first housing and at least the plug-in connection units are arranged outside the first housing.

8 . The connection arrangement according to claim 7 , wherein the carrier is arranged in a sealed manner at the through opening.

9 . The connection arrangement according to claim 7 , wherein the connection strip is arranged on the first component, which is part of a third component that is different from the second component, in particular is part of a second housing that is different from the first housing, on which the contacting unit is arranged.

10 . The connection arrangement according to claim 7 , wherein the connection strip is arranged on the first component, which represents part of an electromagnetic shielding of the connection strip.

11 . The connection device according to claim 2 , wherein the contacting unit has multiple contact pairs arranged on the same side of the carrier.

12 . The connection device according to claim 2 , wherein the carrier of the contacting unit is arranged on the second side of the connection strip.

13 . The connection device according to claim 3 , wherein the carrier of the contacting unit is arranged on the second side of the connection strip.

14 . The connection device according to claim 2 , wherein the contacting unit is designed to be spatially separated from the connection strip, and the line arrangement has a connecting portion via which the contacting unit and the connection strip are connected.

15 . The connection device according to claim 3 , wherein the contacting unit is designed to be spatially separated from the connection strip, and the line arrangement has a connecting portion via which the contacting unit and the connection strip are connected.

16 . The connection device according to claim 4 , wherein the contacting unit is designed to be spatially separated from the connection strip, and the line arrangement has a connecting portion via which the contacting unit and the connection strip are connected.

17 . The connection device according to claim 2 , wherein the connecting portion of the line arrangement is designed to be flexible.

18 . The connection device according to claim 3 , wherein the connecting portion of the line arrangement is designed to be flexible.

19 . The connection device according to claim 4 , wherein the connecting portion of the line arrangement is designed to be flexible.

20 . The connection device according to claim 5 , wherein the connecting portion of the line arrangement is designed to be flexible.
