Abstract
An insert-rack plug connection can be created between at least one sleeve portion (2) on a relatively fixed-position mother board (3) and at least one plug portion (4) on a relatively mobile daughter board (5). With that, the plug arrangement comprises a plug housing (6) mounted to displace axially on the daughter board and possessing a plug ferrule (7) mounted under preloaded axial spring tension. In addition, engagement means (8) for engagement of the plug housing into an engagement position in the sleeve portion are provided on the plug housing. In the insertion direction (x), the plug housing (6) is supported either directly of indirectly on a spring-action thrust element (9), the spring force of said thrust element maintaining the support until the engagement position has been reached, and subsequently automatically releasing said support on continued thrust movement. In this way, the daughter board (5) can be mechanically decoupled from the plug ferrule (7) or from the mother board (3) after reaching the engaged position in order to compensate mass tolerances. A U-shaped fork (9) preferably serves as a spring-action thrust element, the spring-action fork prongs of said fork b…
