Definitions

  • Expandable housing made of mounting frame
  • the invention relates to a housing expandable from assembly frames with at least one circuit board in stacks according to the preamble of the main claim.
  • the housing is essentially made up of flat components with a three- or four-walled frame.
  • the circuit boards are arranged parallel and at a distance from one another, the plug connections of the circuit boards being electrically contactable with one another via openings in the flat component.
  • Two components are mechanically connected to one another using dowel pins attached to the frame, the dowel pins being inserted into the bores of the other component.
  • elastic pawls are used, which engage in assigned slots.
  • the invention has for its object to provide an expandable housing formed from a mounting frame, in which simple assembly and disassembly is possible.
  • the mounting frames comprise a latching and unlocking device according to the invention, it is possible to easily close intermediate mounting frames in a stack of mounting frames remove or insert additional mounting frame, whereby by a locking function with respect to an adjacent second mounting frame, the mounting frame can be fixed to one another, the second mounting frame having locking means for this purpose, and on the other hand an unlocking function for the same locking means for releasing the mounting frame.
  • the latching and unlocking device consists of at least one spring-loaded latching element which is designed in such a way that it can engage with latching means, as a result of which tool-free assembly of assembly frames, including intermediate frame modules, is possible, the latching element being designed in such a way that it can be released from the locking means by actuation — against spring force — an exchange or removal of the mounting frame is also possible.
  • the latching and unlocking device can be provided with at least one actuating means accessible from the outside, the actuating means preferably being designed as a push button. Furthermore, a particularly convenient tool-free assembly is possible, with a simple
  • the slide has two locking recesses, which are spaced from each other by a sixth to a third of the dimension (length) of a slide side of a mounting frame and are arranged in the central region of the mounting frame, on the one hand there is an optimal locking function and on the other hand it is possible to to form an arcuate guide edge covering the locking recesses, which gives a special aesthetic impression.
  • the latching and unlocking device comprises a plate-shaped, elongated slide which is guided and supported in a linearly displaceable manner, if the slide further has at least one curved contour which has a locking slope (for automatic Has snap), which is designed such that the slide is displaceable against the spring force, has an opposite unlocking slope, and has a locking recess arranged below the locking slope, wherein the unlocking chamfer attaches to the locking recess.
  • the high tensile forces caused by the pin and socket strips are greatly reduced by the corresponding curve of the unlocking slope.
  • the latching recess engages behind the locking means, two slides being arranged opposite each other, on opposite slider sides, in pairs.
  • the slide is particularly easy to assemble with good guiding properties and easy to manufacture.
  • the slide of the latching and unlocking device hereby has at least two aligned guide holes similar to slots, in which guide cams are arranged.
  • the guide cams in the guide area have a substantially rectangular cross-section and a T-shaped guide head, the guide holes have an insertion opening which is adapted to the head shape of the guide head, and at least one slide stop is arranged within the guide holes and / or the insertion opening.
  • the invention enables the assembly frame to be assembled quickly into a housing by simply plugging it together and locking it independently.
  • the electrically conductive connection by using metal slides is advantageous. Through the metal parts (slider, locking pin) the electrical contact is passed from frame to frame, especially when the mounting frame is made of die-cast metal. This eliminates the need for additional contact elements or contact connections for grounding.
