Description

χ 112774

BACKGROUND OF THE INVENTION The invention relates to a housing for mounting electrical or electronic components or assemblies, the housing having a front plate and a frame extending around the front plate, whereby the frame is lockable at different heights on the side walls of the housing.

10 In a well-known case of this type ("Bureaux d'Etudes Automatismes"

Well. 28,1987, Paris, pages 44-48) are provided with only two different mounting positions for the frame, one with the front panel included and the other with the front panel missing.

From this known type of casing, it is an object of the invention to provide a casing such that it can be fitted to front panels of different thicknesses.

The solution to this problem is, in accordance with the invention, that the frame is locked by the locking protrusions or locking troughs and the locking troughs or locking protrusions arranged on the sidewalls of the housing, and that the frame rests at a height of

In a preferred embodiment of the invention, the frame comprises at least approx. full U-shaped cross-section with the bottom facing away from the front panel and * »# 25 with one branch on the front panel.

The development according to the invention is particularly technically and aesthetically satisfactory. The different thickness of the front panel only results in the outer casing

I t I

Shadow seams of different width are formed on the edge. In contrast, a tight contact is always ensured between the inner edge of the frame: 30 nanoseconds and the front panel so that this; : No dirt can be created in this location.

Figure 2b shows a partial section along planes II-II in connection with a thicker front plate.

Fig. 3a shows a partial section along the plane ΠΙ-HI of Fig. 1 in connection with the thickness of the front plate according to Fig. 2a, Fig. 3b shows a partial section just above plane III-III of Fig. 1 with a thickness corresponding to Fig. 2b,

Figure 4 shows a perspective view of a portion of the box base.

20 A front · is placed on the bottom of the housing 3, which is provided with the side walls 3a. i 'plate 2a or 2b over which the frame 1 extends. The side wall 3a has a different inside,; 'Troughs 3c. One of these retaining troughs is provided, depending on the thickness of the front panel 2a or 2b, respectively, inside the frame 1. the locking protrusion le in the leg le. Each of the narrow sides is provided with shaped fastening holes 3b to which the pins 1f of the frame 1 engage in a clamping manner. On the outside of the mounting holes 3b are provided counter-grooves 3e of different heights * ;;; keuksille. One of the locking troughs 3e in each case engages one locking lug 30 of the frame 1.
