Definitions
- the invention relates to an installation housing which is closed by a cover and is provided with a strain relief at a cable entry opening.
- Installation housings such as those used for miniature circuit breakers and residual current circuit breakers or for other devices that can be arranged on mounting rails, are usually riveted or screwed together.
- installation housings for devices in building system technology one would also like to provide strain relief means for cables to be introduced, in order to relieve cables at terminals, as are common in general installation technology, against train. At the same time, one wants to save space and get by with thin housing walls for economic reasons. Conventional strain relief devices cannot then be attached.
- the invention has for its object to develop an installation housing, which is closed by a lid and provided with strain relief, which is particularly economical to manufacture and assemble.
- the described object is achieved by an installation housing according to claim 1.
- the installation housing in particular for building system technology, has a molded part with at least one clamping lip between walls that may not be sufficiently connected, which part can be inserted between the walls.
- at least one clamping plane in which opposing gripping tabs of the walls are clamped by the arms of the molded part engaging behind them the molded part is secured against tilting by means of guides on the molded part and walls.
- it fulfills three functions, namely tensioning, jamming a line and guiding against tilting. Tensioning eliminates the need for conventional tensioning devices such as rivets, screw connections or gluing in this area.
- the molded part can only be used with the intention of bracing a housing with its cover without providing strain relief.
- the molded part can then be made correspondingly simplified.
- the molded part forms gripping edges or knobs on an externally accessible side in order to make it easier to release by hand. It is also advantageous to make recesses or support ribs for tools, such as screwdrivers, on which the molded part can be gripped and lifted.
- the engaging arms of the molded part can be designed in a simple manner in the manner of tongue and groove for a connection.
- the installation housing 1 according to FIG. 1 is closed by a cover 2.
- a molded part 3 is inserted between the side walls and forms a clamping lip 4 for clamping a line 5 to counter-clamping areas 6.
- the molded part 3 has a clamping plane in which opposite gripping tabs 7 of the walls are clamped by the arms 8 of the molded part engaging behind them.
- One cf. Figure 2. By guide means 9 on molded part 3 and walls of the installation housing, cf. Figures 3 and 6, the molded part 3 is secured against tilting.
- gripping edges 10 are formed on one side of the molded part 3 that is accessible from the outside.
- gripping edges 10 are formed on one side of the molded part 3 that is accessible from the outside.
- the molded part 3 can be gripped behind with a tool in the manner of a screwdriver 13 and lifted out or levered out under support on housing edges.
- the engaging arms 8 of the molded part 3 are designed in a particularly simple manner in the exemplary embodiment for a tongue-and-groove connection, the side walls of the housing, or the cover of the housing, forming U-shaped gripping tabs 7.
- the guide means 9 on the molded part 3 are each advantageously designed as resilient arms with snap hooks 14 according to FIGS. 3 and 4 in such a way that they can lock behind a knob in the guide means in the wall.
- the molded part 3 is then secured against being pulled off; however, it is releasable if the spring force is overcome.
- the molded part 3 is seated in front of a clamp body 15 with clamps for connecting conductors. Screwless clamps which can be opened by means of opening members 16 are expediently used.
