Description

Insert box for electrical equipment

The object of the innovation is an insert socket for electrical Devices to which box cover plates can be attached / which differ in terms of the center distance between Differentiate between fastening screws.

This box is essentially characterized / that two pairs of projections are provided near its opening are, wherein the projections of each pair are diametrically opposite one another, the two pairs of projections in more preferred Arranged at right angles to each other, the projections of each pair have different dimensions than those of the other Pairs have such that according to the axis of the can aligned openings are provided which with respect to their distance from the pair of protrusions au pair of protrusions.

The fact of the arrangement of the two diametrically opposed projections solves for each center distance not only the problem of the possibility of fixing according to the norms of different countries dimensioned plates on the box, but also enables the installation of devices in the box, especially of interchangeable devices whose space requirements are greater than the minimum distance between them Is the projections that have the smallest center distance.

The subject of the innovation is shown in the drawing; in this show:

Figure 1 is a plan view of the can,

Figure 2 is a section along the line II-II of Figure 1 and

Figure 3 shows a section along the line III-III of Figure 1.

As shown in the figures, a can 1 has a substantially circular or polygonal cross section a first pair of inner projections 2 and 3, which are arranged diametrically opposite each other, and a projection of the side wall of the can 1, and a second pair of inner projections 4 and 5, which are also are arranged diametrically opposite one another and preferably at a right angle to the arrangement of the pair of projections 2 and 3 are arranged.

The projections 2 and 3 protrude slightly further than the projections 4 and 5, in such a way that between the projections 4 and 5 apparatus or devices with a noticeably larger space requirement than the minimum distance between the a projections 2 and 3 can be arranged.

■ The projections 2 and 3 have openings 2 'and 3 ¹ ,

which are aligned according to the axis of the can 1 and widened at the ^{top by chamfers 2 '1} and 3 ^11. The openings 2 ¹ and 3 ¹ have a predetermined center distance I.

The projections 4 and 5 are in the same way apertures .4 'and 5 ^1, aligned with the axis of the can 1 and are flared also above by chamfers 4 ¹¹ and 5 ^11, wherein between them an axial distance I ¹ is greater] than the center distance I is provided.

The openings 2 ¹ , 3 ', 4 ¹ and 5' are preferably intended to receive thread-cutting screws. The box 1 described in this way can therefore be used for two different center distances that are provided in electrical apparatus or devices, and the same socket can accommodate electrical apparatus or devices of variable or different space requirements, in particular devices or devices whose space requirements are greater than the minimum distance between the projections 2 and 3 is.

Thus, the socket according to the innovation not only facilitates the work of installation, but also enables it economical tooling for the fitter's manufacture and storage of cans.

Of course, the innovation is not limited to the embodiment described above and shown in the drawing.

} form, but numerous changes in detail can be provided without changing the scope of the innovation.

Claims (1)

Einsefczdose for electrical apparatus or devices, characterized in that in the vicinity of its opening a first pair of diametrically opposed projections (2, 3), which form a projection of the side walls, and a second pair of diametrically opposed projections (4, 5) are provided, wherein the one pair of protrusions is preferably arranged perpendicular to the orientation of the other pair of protrusions, the first pair of protrusions (2, 3) protrudes slightly further than the protrusions (4, 5) of the other pair in such a way that in the Distance between the projections (4, 5) of the second pair of devices can be installed with a space requirement that does not allow their installation between the projections (2, 3) of the first pair, the projections (2, 3) of the first pair corresponding to the axis of the Can (1) have aligned openings (2'f 3 ') whose center distance (I) is smaller than the center distance between openings (4 ¹ , 5 ¹ ) of the projections 7731104 01/19/78 (4, 5) of the other pair, whose projections (4, 5) are also aligned with the axis of the can (1), and these openings (2 ', 3', 4 ¹ , 5 ') for receiving in preferably self-tapping screws are suitable and intended for the fixation of cover plates carrying electrical devices or apparatus. 7731104 19.0178
