Plug receiver with contact springs for a circuit board

1. A plug receptacle for an electrical plug-in connection, the plug receptacle comprising:

a housing with an insertion region into which a plug can be releasably inserted;

an electrical plug receptacle conductor rigidly arranged in the housing; and

an electrical connecting conductor floating in the housing configured to electrically connect the plug receptacle, conductor to a plug conductor, wherein the floating electrical connecting conductor is not fixedly connected to any other element of the electrical plug-in connection;

wherein the electrical connecting conductor exerts a connecting force onto a contact region of the plug conductor once inserted into the plug receptacle; and

the connecting, force runs substantially orthogonally in relation to said contact region.

2. The plug receptacle as claimed in claim 1 , further comprising a locking element to move linearly within the housing;

wherein the locking element interacts with the connecting conductor and moves along a linear movement path between a locking position, wherein the plug is held in connection to the plug receptacle, and an unlocking position wherein the plug is not held in connection to the plug receptacle.

3. The plug receptacle as claimed in claim 2 , wherein the linear movement path of the locking element runs substantially orthogonally in relation to the plug conductor.

4. The plug receptacle as claimed in claim 1 , further comprising:

a shaft arranged to rotate within the housing; and

a lever is rigidly connected to the shaft, wherein the lever interacts with the connecting conductor and can be moved between a locking position, in which the plug can be fixedly connected to the plug receptacle, and an unlocking position in which the plug can be released from the plug receptacle.

5. The plug receptacle as claimed in claim 1 , wherein the electrical connecting conductor comprises an electrically conductive helical spring.

6. The plug receptacle as claimed in claim 5 , further comprising a lever with a passage opening through which the electrical connecting conductor at least partially extends and a stop face at least partially surrounding one end of the passage opening;

wherein the helical spring includes a first region with a first diameter and a second region with a second diameter smaller than the first diameter; and

one end of the first region adjacent the second region makes contact with the stop face when the lever is in the locking position.

7. The plug receptacle as claimed in claim 4 , wherein the lever includes a first locking section to engage with a second locking section of the plug when the plug is inserted and the lever is in the locking position.

8. The plug receptacle as claimed in claim 7 , wherein:

the first locking section comprises a projection from the lever; and

the second locking section comprises a recess in the plug into which the projection can at least partially project when the plug is inserted and the lever is in the locking position.

9. The plug receptacle as claimed in claim 1 , wherein:

the housing comprises a first housing element and a second housing element arranged to move relative to the first housing element between a release position and a blocking position;

the first housing element includes the insertion region; and

the second housing element, when in the blocking position, prevents release of the plug from the plug receptacle, and allows, when in the release position, release of the plug.

10. A plug-in connection comprising: a plug receptacle comprising:

a housing with an insertion region into which a plug can be releasably inserted;

an electrical plug receptacle conductor rigidly arranged in the housing;

a first locking section; and

an electrical connecting conductor floating in the housing configured to electrically connect a plug receptacle conductor to the plug conductor, wherein the floating electrical connecting conductor is not fixedly connected to any other element of the electrical plug-in connection;

wherein the electrical connecting conductor exerts a connecting force onto a contact region of the plug conductor once inserted into the plug receptacle; and

the connecting force runs substantially orthogonally in relation to said contact region; and the plug comprising:

a substantially plate-like body movable between an unplugged position, in which the plate-like body is detached from the plug receptacle, and an inserted position, in which the plate-like body is inserted into the plug receptacle and electrically connected to the plug receptacle conductor;

an electrical plug conductor attached to a surface of the plate-like body and comprising a contact region; and

a second locking section on the plate-like body to engage with the first locking section when the plate-like body is in the inserted position;

wherein the plug can be releasably connected to the plug receptacle.
