Built-in housing

The innovation relates to a built-in housing, in particular for electrical devices and components, with a base part and a cover part that complements the installation housing to form a cuboid.

Installation housings of this type are known in a wide variety of designs. With the usual installation housings of the known type, the cover part is applied from above to the bottom part and then with screws or the like secured against an opening force transversely to the usually horizontally extending parting line. Without securing with screws or other fastening elements, the housing can be easily attached by simply pulling off the cover part upwards be opened.

Based on this prior art, the object of the innovation is to provide a housing of the type mentioned at the beginning train that it is perpendicular to the bottom or top surface even without the provision of additional separate fastening elements directed tensile forces is secured.

This object is achieved in a built-in housing of the type mentioned in that the base and cover part Have end faces of different heights and the side faces one from the higher to the lower end face Have parting line, being adjacent to at least one end face in the side faces parallel to the bottom and Lid surface extending, interlocking locking elements are provided, which are opposite to each other Hold the edges of the front and side surfaces in the contact position.

It has proven to be useful that the parting lines of the side surfaces from the lower level over an ascending one Area to a middle level, which extends parallel to the top and bottom surfaces, and over a second rising area to the maximum level, the locking elements being provided in each case at the rising areas.

Such a housing is opened and closed by a pushing together or pulling apart in a direction running parallel to the top and bottom surface. By providing the In the closed state, locking elements cannot be separated under the action of force transversely to the cover or bottom surface possible. The design of the housing according to the invention also provides particularly good accessibility to it Interior achieved. This is particularly useful when one or more printed circuit boards are in the housing Circuits and electrical components are to be inserted. This can be done very easily from the lower face made from.

It has proven to be useful that the locking elements sit on the one hand on projections that rise from the first Area extending in the direction of the lower end wall and on the other hand arranged behind the second rising area are.

In a preferred embodiment, the locking elements are on the one hand by opposite the neighboring outer housing surfaces formed back, parallel to the bottom and top surface extending tongues and on the other hand by grooves whose The reason is also opposite to the outer surface of the housing.

Such a configuration ensures that the locking element are not visible from the outside. This allows an aesthetic particularly attractive design of the housing.

According to a further feature of the innovation, c.e grooves and the springs in the closed position of the housing on interlocking locking elements which hold the housing in its closed position.

In a preferred embodiment, the locking elements are transverse for the longitudinal extension of the grooves and tongues extending Rasrrippen and locking grooves.

According to a preferred exemplary embodiment of the innovation, the base part and the cover part, possibly except for different ones Heights of the side surfaces, essentially identical. In the case of completely identical training, an injection molding tool is sufficient for producing a two-part housing. With an identity with the exception of the different heights of the side surfaces can possibly the same tool can be used for the different parts, which only changes by adding additional parts will.

The housing described is locked in the closed state. It can can also be secured in the locked position if, according to Another feature of the innovation, the cover part through openings for fastening screws that can be screwed into opposing eyes in the bottom part.

The housing in accordance with the innovation is of great advantage as a plastic Injection molded part formed.

The following is a preferred embodiment of the innovation described in detail with reference to the drawing. The only figure in the drawing shows an exploded perspective view an open housing consisting of two essentially identical parts.

In the exemplary embodiment shown, parts that correspond to one another are denoted by the same reference numerals and a prime. The bottom part 1 corresponds to the substantially identical lid part 1 ^1, which only differs from the base part, that it / has two through holes 11 and 12 for zv ei fastening screws 9 and 10 which are not provided in the Bodehteil, but may be provided there as well . In addition, the cover part 1 ′ could also be designed without the through openings 11 and 12.

The bed part 1 has two side walls 2 and 3, also one higher end face 8 and a lower end face 26. The The joint between the two housing parts runs from the lower end face over a first rising area to a middle level3lund from there over a second rising area 32 up to the level of the end face 8. The together engaged edges have in a known manner grooves 4 and 5 and tongues 6 and 7, which with the corresponding Counterparts are engaged on the other housing part.

The fastening screws 9 and 10, which extend through the passage openings 11 and 12, are screwed into the eyes 13 and the bottom part 1. Behind the rising Bodenbe rich 32 grooves 15 and 16 extending parallel to the ground are provided in the bottom part 1. Above these grooves are inward

11 965 October 26, 1979

pointing projections 21 and 27 are present. The grooves 15 have inwardly facing locking lugs 17, only one of which is visible is.

The corresponding counterparts are arranged on the first protruding area 30. There are springs 18 and 23 which have locking grooves 20 and 24. A recess 19 is provided below the spring 18. Below the spring 23 is a return 22. The corresponding configuration shows the cap portion 1. ¹ When the housing is pushed together in the direction of arrow 25, the tongue 18 enters the groove 16 and the projection 21 engages in the recess 19.
