Abstract: A system is provided for releaseably connecting a first device housing with a second device housing. The system includes at least three connection units, wherein each of which includes a headed bolt and a corresponding keyhole-shaped recess. The keyhole-shaped recess is configured for receiving the headed bolt such that the headed bolt can be inserted into the recess in a first section and held in the recess in a second section. At least one of the connection units includes a locking mechanism configured for locking the bolt in the second section of the recess. The locking mechanism includes a movable locking element which is movable with respect to the headed bolt and configured to hold the headed bolt in the second section of the recess in a locking position. Another configuration uses a corresponding connection arrangement includes such a system.

Abstract: A holding device for a device comprises a mounting part, an anchor part which is configured to be fixed to a housing of the device and a locking element which is partially arranged in the mounting part and which is rotatable within a defined angular range from a release position to a locking position in order to fix the anchor part to the mounting part.

Abstract: A box-frame housing for the installation of electronic modules has frame elements and side walls and provides a subdivision into sub-regions, which are limited by dividing walls. The frame elements and the side walls and the dividing walls provide at least one recess and/or at least one edge projection. A projection engages in a recess and both are connected to one another by welding.

Abstract: A locking system for fitting and securing modules in a housing includes at least one module, which is surrounded by a chassis and provides a plug connection at a rear side. The front side of the module disposed opposite to the rear side provides a chassis front-plate connected to the chassis. Each module can be locked by a snap-in locking device in a housing, into which the module is pushed. In order to release the snap-in locking device, an opening tool engages in the chassis front-plate. A pulling stress can be exerted on the chassis front-plate by the opening tool, and the module can be withdrawn from the housing.
