Connection system

Claim 1

A connection system, comprising: a holder having longitudinal sides, an upper side, and holding rails disposed on said longitudinal sides; and an electronic component releasably mechanically connected to said holder and covering at least an amount of residual travel before arriving in an end position, said electronic component having longitudinal sides with two holding regions disposed on each of said longitudinal sides and interacting at least partially said holding rails during the residual travel; each of said holding rails having two gaps formed therein for allowing a vertical insertion of said holding regions perpendicularly in relation to said upper side of said holder, the residual travel into the end position taking place exclusively along a pushing-in direction running parallel to said upper side of said holder, said gaps formed in said holding rails lying opposite one another being space apart by a first distance along the pushing-in direction from each other; said holding regions being rear-engagement devices being disposed, as seen in the pushing-in direction, one behind another and, during the residual travel, gripping at least partially under said holding rails; said gaps being formed to cause said rear-engagement devices leading in the pushing-in direction to pass said gaps during a mounting operation without being able to come away from said holder transversely in relation to the pushing-in direction; and said corresponding rear-engagement devices lying opposite one another being spaced apart by a second distance along the pushing-in direction from each other and the second distance being less than the first distance.
