Mounting device for fastening a module onto a component, in particular an outside housing of another module

A mounting device for fastening a module onto a component, said mounting device comprising

• (a) a fastening screw, said fastening screw further comprising;
• (i) a screw head;
• and (ii) a screw shaft comprising a thread;
• (b) a screw carrier connected to said module to receive said screw shaft, said screw carrier designed as a fastening flange having a through-opening to receive said screw shaft, and a bushing shaped onto said fastening flange in which a spring element is guided on said screw head end on said through-opening;
• and
• (c) a thread carrier,
• wherein said thread carrier is connected to said component and further comprises an inside thread corresponding to said thread of said fastening screw,
• wherein a force-locking connection between said screw carrier and said thread carrier is established by means of said fastening screw in a fastening position, and said module is supported on a supporting element of said component in said fastening position;
• wherein said shaft has a front shaft section having said thread, such that said front shaft section is accommodated by said inside thread in said fastening position, and wherein said shaft has an additional shaft section to receive said spring element, said additional shaft section being connected to said front shaft section on said screw head end, such that said spring element is pre-stressed against said screw carrier and a stop on said screw head end when said fastening screw is screwed into said inside thread so that said module is pressed against said supporting element and in said fastening position of said front shaft section which is completely screwed into said thread carrier, a gap remains between said thread carrier and said screw carrier;
• wherein a peripheral collar is provided on said additional shaft section as a second stop on said screw head end between said front shaft section and said screw head;
• and
• wherein a sleeve is provided on said through-opening, said sleeve having an inside diameter such that said spring element on said additional shaft section is capable of being inserted into said sleeve.
