Enclosures for mounting electrical and/or electronic accessories

The invention relates to a housing for the installation of electrical and/or electronic accessories, comprising a housing, in the front area of the housing, two profiled posts, wherein on the two profiled posts are fixed The fixing part of the inner cavity has a supporting section, by means of which a component bracket of a standard installation width can be fixed between two type columns.

Such a housing designed as a switchgear is known from German Patent Application Published Specification DE 4341943A1. The shell has a base on which four vertical columns are fixed. The profile column, which is designed as an extruded profile, has a seat facing the interior of the housing. Fixtures can be incorporated into these mounts. The fixing part has a supporting surface, which is supported on the supporting surface of the mounting base. The fastening element has a strip-shaped support section, which extends parallel to the front side of the housing and at a distance therefrom. A component support extending in the width direction of the housing can be fastened to the support section. In order to be applicable to component supports of different depths, the fixing part can move along the depth direction of the shell.

The technical problem to be solved by the present invention is to provide a housing of the aforementioned type which allows more varied installation possibilities in the interior of the housing.

In order to solve the above-mentioned problem, the supporting section of the fixing part can be adjusted back and forth along the width of the housing by means of an adjusting device between at least two installation positions, wherein the installation positions each define a standard installation width dimension. With this design, one type of enclosure can be applied to different mounting systems. This adaptability can be easily achieved. In particular, no additional adapters of any complex design are required.

According to a preferred embodiment of the invention, the support section is adjustable back and forth between 9.5" and 10" installation width dimensions.

If the shell of the present invention adopts such a structure: the fixing member is made into a profile rail extending in the vertical direction, and is equipped with a supporting section extending longitudinally along the profile rail and having a structure of a rear slit (hinterschritte Nut), then the assembly bracket can be relatively Height adjustment on profile rail. A plurality of module racks can thus be arranged compactly in rows with one another. In a preferred manner, the fastening element is designed as an extruded profile, the groove being formed in the extruded profile.

One or more component holders can be fixed on one fixing piece. If a plurality of fastening elements are mounted one above the other on a profile, it is desirable to group these component supports closely together. In view of this, the further improved structure of the present invention is: the type column has a fixing groove extending along its longitudinal direction; the groove area of the opening is connected with a supporting surface of the type column; the fixing member is supported by a fixing section; Insert at least one nut for screwing the fastening section.

A simple structure is provided if the fixing section has an elongated hole perpendicular to the longitudinal extension of the profile, through which a fixing screw is inserted and screwed into a nut seated in the fixing groove.

A possible variant of the invention provides that the bearing section of the fastening element is adjustable in the depth direction of the housing.

The present invention will be further described below with the help of the embodiments shown in the accompanying drawings.

Figure 1 is a top view of the housing with the cover removed;

FIG. 2 is a partial detail view taken from FIG. 1 .

Figure 1 depicts a top view of the housing with a cover removed. The shell has four vertical columns 10, which are extruded profiles. The cross-sectional geometry of the column 10 can be seen clearly from FIG. 2 , and will be further described below.

FIG. 2 shows a partial detail view taken from FIG. 1 . The structurally identical profile 10 has an undercut 15 in the region of its front side facing the housing interior. In the region of the slot opening adjoins a bearing surface 16 perpendicular to the front side of the housing. At its end facing away from the housing front, the bearing surface 16 merges into a section parallel to the housing front. Together with this part, the bearing surface 16 is used for mounting a hinge part 21 of the door hinge. The hinge part 21 has fixing through holes. Fixing screws can pass through these fixing through holes and be screwed in the nuts contained in the back slot 15 . The hinge part 21 is connected to another hinge part 22 via a hinge connection part 25 . This further hinge part 22 is fastened to the front door 23 by means of a screw connection 24 . It can be clearly seen from FIG. 2 that a threaded hole 17 is formed at the bottom of the groove 15 in the outer region of the housing. This threaded hole 17 is used to connect the base 60 to the cover, which cannot be seen in the figures. But its structure is basically the same as the bottom 60. Bottom 60 has fixing through hole, and fixing screw can pass through fixing through hole, and screw in the threaded hole 17 of various types post 10. The profile 10 has a further groove 14 at a distance from the groove 15, which is likewise undercut and opens in the direction of the housing interior.

Groove 14 has the same cross section as groove 15 . The same nuts as used in the groove 15 can thus be inserted into the groove 14 . Fasteners 40 are fixed on these nuts. The fixing part 40 is designed as a profile with an L-shaped cross section. They have a support section 41 with fastening holes. A support leg 43 is arranged at right angles to the support section 40 . The support leg 43 can bear against the support surface 13 adjoining the groove 14 . The supporting leg 43 has two or more fixing holes or a long hole 44 . By means of these fixing holes or this elongated hole 44, the fixing member 40 can be fixedly connected with the nut installed in the groove 14 with screws. Due to the plurality of fastening holes in this support leg 43 or this elongated hole 44 , different installation positions of the fastening element 40 can be realized. In this way, the support section 41 is arranged to be adjustable in the depth direction of the casing. The support section 41 is intended to receive a component bracket mounted near the front side and extending across the width of the housing. Here, the component support can be optionally fixed on two parallel columns 10 facing the front side of the housing or both facing the rear side of the housing.

The profile column 10 has a fastening groove 11 connected to the groove 14 . The fixing groove 11 opens toward the rear side of the housing (for the front side column 10 ) or toward the front side of the housing (for the rear side column 10 ). A bearing surface 12 parallel to the front side of the housing is connected to the notch. The fastening section 32 of a fastening element 30 bears against this support surface. The fixing section 32 is provided with two or more long holes 33 . These elongated holes 33 are aligned with the notches of the groove 11 . The fixing screw can pass through the elongated hole 33 and be screwed into the nut installed in the fixing groove 11 . The fastening part 30 has a support section 31, which is here designed as a groove. The longitudinal direction of the groove extends in the vertical direction. Nuts can be loaded into the rear slot (support section 31). Component brackets extending across the width of the housing are secured to these nuts. Here, the component carrier is fastened to mutually parallel front profile columns 10 by means of fastening elements 30 . The fixing member 30 can be adjusted back and forth between two mounting positions parallel to the front side of the housing. The adjustment movement of the fixing member 30 is limited to stop against the longitudinal side end of the elongated hole 33 . In this way, two installation positions can be determined, which each define a standard installation width dimension. Therefore, a 10" module bracket can be installed between the two fixing parts 30 when in the outwardly moved position. A 9.5" module bracket can be fixed on the fixing parts 30 when the fixing parts are in the inwardly moved position.

Obviously, the fixing member 30 or 40 is installed in the housing in an optional manner.

In the region of the outside of the housing, the vertical profile columns 10 form outer mounts which are delimited by the outer surface 19 of the vertical profile columns 10 and the profile side 18 . The side wall 50 fits into the outer mount. The side wall 50 has a vertical wall with folds 52 on its horizontal sides. Holes 53 are machined in the flange 52 . These through-holes 53 are aligned with through-holes of the same cross-section on the bottom 60 or cover. By aligning the through holes and using clamping elements, the side wall 50 can be connected to the bottom 60 and the cover and thus to the vertical profile 10 .

It can be seen from FIG. 1 that a rear wall 70 is installed on the rear side of the housing. The rear wall 70 is a thin metal plate, and a clamping piece with a lock block 73 can be installed on its side. The clamping part also has a further locking block 72 . The locking block 72 is locked in the fixing angle piece 74 . The fixing angle 74 can be fixed on the groove 15 of the vertical profile 10 .

It can also be seen from FIG. 1 that the bottom 60 has a rectangular cable through hole 61 . Cables can be introduced into the inner cavity of the housing through the cable through hole 61 . Furthermore, a plug receptacle 62 is stamped out of the base 60 . The plug can be screwed in the area of this plug mount 62 .
