Housing made of elastic plastic with an electrical device arranged in it Component.

The present invention relates to a housing according to the preamble of claim 1.

Such a housing is known, for example, from DE-GM 1 945 263. There, locking elements are provided on the bottom, the outer contour of which runs obliquely outwards and then obliquely inwards from the edge to the bottom of the cup.

From DE-OS 2 752 847 locking elements are provided on the bottom, which are designed as outwardly directed locking hooks are.

With the present invention, the object is to be achieved to form the locking elements in such a way that the housing, for example a cup, can be mounted on plates that have a different thickness and in which, if necessary, differ large openings are available.

This object is achieved by the features specified in claim 1.

Further advantageous details of the invention are given in the subclaims and below with reference to the in the Drawing illustrated embodiments described.

With 1 is a housing made of e load i seem plastic, e.g. from Polyethylene, polypropylene, polyamide etc. 'for inclusion electrical components called. Preferably is the housing 1 is cup-shaped and is used in particular * more to accommodate capacitor windings. The case

but can also be used for other components such as, coils, Re " lais, circuits, amplifiers etc. are used.

On the bottom 2 of the housing 1, several opposing latch elements 3 are formed. In the example according to Fig. '10 1, 7, 8, 9, 10 are two> according to Fig. 2 two or four, according to FIG. 3 four and according to FIG. 4 eight locking elements 3 are provided.

_{Each latching element 3 has a latching hook 4.j and 4?} On at least two opposite sides and possibly also on another side. or Fig. 7 locking hooks 4,, 4 ₂ and 4 ₃ . The locking surfaces 5 ^ 5 _2, 5 ₃ of the corresponding locking hooks ⁴ T ⁴ 2 ^'4 3 ^{hi' nter} engage a detent plate 6 or 6 ,, 6 _2, 6, (Fig. 7) to which the housing 1 is mounted. Accordingly, shaped openings 7 are provided in the plate 6 of the arrangement of the latching elements 3, for example in the form of a square according to FIG. 4 or a rectangle according to FIG. 5. When the inwardly projecting latching hooks 4 _? to come into effect, the openings 7 are to be selected so that

■ in the middle of an opening a ridge in the plate 6

remains, which can be accessed from behind by the locking surfaces 5 ^, 5 ₂ , 5 _3.

According to the invention, the locking surfaces 5 ^, S ₂ , S _{3 are provided} at different distances d ^ d ₂ , d ₃ (see. Fig. 1, 2, 3, 7, 8) from the bottom 2, each of at least two locking elements 3 the Latching surfaces 5. or 5 ₂ or 5, the

This distance d *, d _?, D, corresponds in each case to the thickness of a plate 6 *, 6 ^ _f 6, on which the housing 1 is to be mounted (FIG. 7).

According to one shown in FIGS. 8 and 9 advantageous Embodiment of the invention can be on the bottom 2 of the housing 1 a pin 8, as a centering aid and / or for improvement is used to fasten the housing to the plate 6, for example, it is press fit into an opening of the Plate 6 pressed in. For this purpose, it is useful in terms of scope provided with circumferential grooves 9. The pin 8 is advantageously provided on the gate or injection point 10, which occurs in the manufacture of the housing 1 by injection molding.

In order to be able to make the application of the invention even more universal, resilient tolerance compensation members 11 can be attached to the bottom 2 of the housing 1 according to FIGS. This ensures that the housing 1 is properly latched to the plate 6 even if its thickness is not exactly at the distance d,., Dp, d, of a latching surface 5 ,, 5 _? , 5, from the bottom 2 coincides. The tolerance compensation members 11 preferably consist of one or more laterally obliquely protruding resilient ones

Tongues. The tongues 11 can also be used advantageously

if the locking elements 3 each have only a single locking hook 4 (Fig. 10).
