Pressure guide for PCB

A pressure guide arranged in a circuit board housing, a printed circuit board comprising:

• a lower guide bar and an upper guide bar, wherein the printed circuit board is inserted between the two upper and lower guide bars for connecting one edge connector, and a spring element provided within one of the guide bars, wherein the upper and lower guide bars are realized in the form of locating braces that are arranged to both sides of the circuit board in a cover plate and a bottom plate of the circuit board housing surrounding the circuit board, wherein the spring element is arranged within the upper locating brace in the form of an integral element in a mating direction of the circuit board, wherein the spring element is arranged within a cutout in one of the guide bars, the cutout is formed opposite to a rail of each of the guide bars, the spring acting upon one narrow side of the circuit board when being inserted, and subjecting the printed circuit board to a pressure, parallel to a plane of the circuit board, that forces an opposing narrow side of the circuit board against the other guide bar when the printed circuit board is being inserted, thereby achieving precise contact between a plurality of strip conductors on a mating side of said printed circuit board and corresponding electric contacts arranged in a mating slot of an edge connector.
