Abstract

Mechanical mounting devices for an electronic housing in a frame are provided, the electronic housing comprising a front face, a rear face, a bottom and two lateral faces, the frame comprising an opening. The electronic housing comprises, on each lateral face, a mechanical cam having a quarter-circle form, one of the two ends of the cam being terminated by a triangular point the end bearing the point being disposed close to the bottom, the second end being disposed along the front face. The bottom of the frame comprises a bottom abutment parallel to the front face. The opening of the frame comprises two guiding pins disposed on either side of the uprights of the opening and arranged such that each cam can be displaced in rotation on the pin which corresponds to it during the phase of mounting of the electronic housing in the frame.

First claim

The invention claimed is:

1. A mechanical mounting device for an electronic housing in a frame, said electronic housing comprising a front face, a rear face, a bottom and two lateral faces the frame comprising an opening of dimensions similar to those of the front face, wherein:
the electronic housing comprises:
on each lateral face, a mechanical cam having a substantially quarter-circle form, one of the two ends of the cam being terminated by a triangular point directed toward the interior of the circle, the section of said cam being substantially rectangular, the end bearing the point being disposed close to the bottom, the second end being disposed along the front face,
on the bottom, a bottom abutment parallel to the front face so as to form, a groove in the space situated between the bottom part of the front face and the bottom abutment;
the opening of the frame comprises two identical guiding pins disposed on either side of the uprights of the opening and arranged such that each cam can be displaced in rotation on the pin which corresponds to it during the phase of mounting of the electronic housing in the frame;

the assembly consisting of the two cams, the bottom abutment and the guiding pins being arranged such that the position of the electronic housing in the frame comprises two rest positions, a first rest position in which the centering pins are situated at the triangular points of the cams and a second rest position in which the centering pins are situated at the second ends of the cams.

2. The mounting device as claimed in claim 1 , wherein the position of the guiding pins and the form of the cam are arranged such that, during the transition from the first rest position to the second rest position at no moment does the bottom of the electronic housing bear on zones situated in the vicinity of the opening.

3. The mounting device as claimed in claim 1 , wherein the frame comprises a female connector mounted on a cable strand, the electronic housing comprising a corresponding male connector.

4. The mounting device as claimed in claim 3 , wherein the frame is a part of an aircraft instrument panel and in that the electronic housing is an aeronautical display device.
