Abstract

In a plug connection for the direct electrical contacting of contact surfaces on a circuit board, having a plug receptacle associated with the circuit board, into which the circuit board extends, having a plug pluggable into the plug receptacle, which has a contact carrier having contact elements for the direct electrical contacting of the contact surfaces of the circuit board, and having a contact pressure spring device for pressing the contact elements of the contact carrier against the contact surfaces of the circuit board, the contact pressure spring device is provided in the plug receptacle.

First claim

What is claimed is:

1. A plug connection for direct electrical contacting of contact surfaces on a circuit board, comprising:
a plug receptacle: (i) associated with the circuit board, into which the circuit board extends and (ii) having at least two contact pressure springs; and
a plug pluggable into the plug receptacle, which has a contact carrier having contact carrier halves, each contact carrier halve having at least one spring contact element,
wherein when the plug is plugged in the plug receptacle:
the at least two contact pressure springs tension the contact carrier halves of the plug, and
based on the tensioned contact carrier halves of the plug, each at least one spring contact element exerts a force that provides electrical contact with the contact surfaces of the circuit board.

2. The plug connection of claim 1 , wherein the at least one of the at least two contact pressure springs is provided on each side of the circuit board extending into the plug receptacle.

3. The plug connection of claim 1 , wherein each of the at least two contact pressure springs extend over nearly the entire width of the plug receptacle.

4. The plug connection of claim 1 , wherein each of the at least two contact pressure springs is situated at the level of the spring contact elements of the plugged plug.

5. The plug connection of claim 1 , wherein the at least two contact pressure springs form a contact pressure spring device, which engages into the plug path of the contact carrier.

6. The plug connection of claim 5 , wherein the contact pressure spring device extends over nearly the entire width of the plug receptacle.

7. The plug connection of claim 1 , wherein multiple contact pressure springs from the at least two contact pressure springs are provided along the width of the plug receptacle.

8. The plug connection of claim 5 , wherein the two contact carrier halves are connected to each other in a hinged manner, between which the circuit board is provided, and wherein the contact pressure spring device presses the two contact carrier halves and the spring contact elements against the contact surfaces of the circuit board.

9. The plug connection of claim 1 , wherein respectively one tension spring is provided in the plug receptacle respectively laterally next to two lateral edges of the circuit board extending into the plug receptacle, which tension spring engages into the plug path of the plug and braces the plugged plug within the plug receptacle perpendicularly to the force exerted by each at least one spring contact element.

10. The plug connection of claim 1 , wherein the force exerted by each at least one spring contact element corresponds to a tension force from the tensioned contact carrier halves of the plug.

11. The plug connection of claim 1 , wherein each of the at least two contact pressure springs provide a tension force directly onto each of the contact carrier halves on an area directly above the at least one spring contact element as a knife-edge load.
