Abstract

A connection device for connecting an electric vehicle for a charging process includes at least one receiving profile which is open to one side for receiving at least one module, wherein one side of a housing of the module forms part of an outer surface of the connection device.

First claim

1 . A connection device for connecting an electric vehicle for a charging process, comprising at least one receiving profile open at one side for receiving at least one module, wherein the at least one module includes a housing having a first side configured to form part of an outer surface of the connection device when received by the receiving profile.

2 . The connection device according to claim 1 , wherein the at least one module has a plug-in connector on at least one additional side of the housing to electrically contact an adjacent module inserted into the receiving profile, the adjacent module including a housing having a first side and a plug-in connector on at least one additional side.

3 . The connection device according to claim 2 , wherein the plug-in connectors are arranged on opposing sides of their respective module housing.

4 . The connection device according to claim 2 , wherein the modules each include two plug-in connectors arranged on the at least one additional side of their respective housing.

5 . The connection device according to claim 4 , wherein when the modules are connected to one another via the plug-in connectors they are arranged one behind the other viewed in the longitudinal direction of the receiving profile.

6 . The connection device according to claim 4 , wherein one of the plug-in connectors of one module is connected to one of the plug-in connectors of the opposing module such that a current path is formed.

7 . The connection device according to claim 4 , wherein two independent current paths are formed between respective plug-in connectors on opposite sides of the module housings.

8 . The connection device according to claim 7 , wherein the two independent current paths intersect inside at least one module.

9 . The connection device according to claim 2 , wherein the plug-in connector is configured in the housing with lateral play.

10 . The connection device according to claim 9 , wherein the plug-in connector has a plug-in body having at least one contact therein, the plug-in body having a circumferential edge inserted into a groove of the module housing.

11 . The connection device according to claim 10 , wherein spring arms stick out on the circumferential edge and position the plug-in body in the groove.

12 . The connection device according to claim 2 , wherein the plug-in connector comprises contacts for at least one of an operating current, contacts for data, and signals.

13 . The connection device according to claim 1 , wherein the receiving profile has a u-shaped or c-shaped cross-section.

14 . The connection device according to claim 1 , wherein the at least one module is concealably screwed into the at least one receiving profile.

15 . The connection device according to claim 1 , wherein the connection device is configured as a battery charging station having two receiving profiles adjoining one another such that their open sides open in opposite directions.

16 . The connection device according to claim 1 , including a wall-mountable receiving profile.

17 . The connection device according to claim 1 , wherein the module has at least one of an operating unit, a plug socket or a power meter.
