Claim:
A magnetomechanical connection assembly consisting of two connecting modules each including a load housing for connecting two elements, to each of which one of the connecting modules can be attached, wherein the connecting modules to be closed can be preloaded with a load F L which substantially acts in direction of a connecting line between the load housings, the connecting line being in the longitudinal direction of the connecting modules in attachment, and the connecting modules have the following features: a locking device with a spring locking element which is arranged in the first connecting module, and a locking piece which is arranged in the second connecting module, for positively locking the connecting modules, a magnet-armature construction with a magnet which is arranged in one of the connecting modules, and an armature or a second magnet, which is arranged in the other connecting module, and a movement track in the first connecting module, on which the locking piece of the second connecting module can be shifted from a closed position into an open position, wherein the locking device, the magnet-armature construction and the movement track are operatively connected by the following features: a. on opening, the connecting modules are shifted on the movement track from the closed position into the open position, wherein the magnet and the armature or the second magnet are shifted against each other, so that a gradual attenuation of the mutual attraction occurs, and b. on opening, the connecting modules are shifted on the movement track from the closed position into the open position, wherein the locking piece and the spring locking element are shifted against each other without urging the spring locking element to the side, until the spring locking element no longer is in engagement with the locking piece; and on closing, the connecting modules snap into the closed position by means of the locking device, wherein the locking piece pushes the spring locking element to the side against a spring force of the spring locking element until the spring locking element snaps into place; and c. on closing, the magnet-armature construction pulls the connecting modules towards each other, whereby the locking of the locking device is at least supported, wherein the position of the load housings on the connecting modules and the position and shape of the movement track are formed such that on shifting the connecting modules from the closed position into the open position the load housings are moved towards each other by an amount Δx parallel with the connecting line and against the load F L when applied to the connecting modules, so that for opening the physical work W=F L ×Δx is required and thus the connection assembly is harder to open under the load F L than without the load F L .
