Plug connector for circuit board connection

A plug connector for a circuit board connection possessing a plug strip (1) mounted on the circuit board and a plug part (5) that includes a socket housing (8) projecting on the plug side that possesses a generally rectangular cross section with longitudinal sides (9, 10) opposite each other, and a face side (11) located between them, whereby insertion guide holes (12) with adjacent plug receptors for contact pins (4) are located on this face side (11), said pins being firmly positioned on the plug strip (1) with alignment matching the plug receptors and insertion guide holes (12), characterized in that the plug strip (1) is formed as an angle strip with a first strip shoulder (2) and a second strip shoulder (3) perpendicular to the first strip shoulder, and wherein the contact pins (4) are mounted either on the first or on the second strip shoulder (2, 3), whereby engaging hooks (13) are present on each of the two strip shoulders (2, 3) on an inner side of said first strip shoulder and said second strip shoulder (2.1, 3.1) facing the plug part (5) that are mirror images with respect to an angle-bisecting plane of the plug strip (1), and engaging steps (14) are provided in the vicinity of the two longitudinal sides (9, 10) of the socket housing (8) on the plug part (5) that are configured to be engaged by the engaging hook (13) of the plug strip and whose separation from the adjacent edges between the pertinent longitudinal side (9, 10) and the face side (11) of the socket housing (8) or a theoretical edge line corresponding to the mirror-image positioning of the engaging hooks (13) is the same.
