Small distribution box c

Small distribution boxes are available in different shapes and sizes
different materials are known, whereby there is a certain dependence of the spatial shape on the material. When using plastics, their physical data after polymerisation must be taken into account. In the course of time, there will also be aging symptoms. Spatial shapes that initially appear favorable turn out to be unfavorable and dangerous in the course of time due to the emergence of brittleness.

It was therefore a small distributor housing to create that in optimal Combination of rough uniform and material in such a way that

cine ensures long life and operational reliability and that avoids the disadvantages mentioned.

It has now been found that such a small cabinet can be used can create if a polyurethane foam main part, consisting of base plate, side walls, rear wall and roof two Polyurethane foam front panels are assigned.

It is advantageous if there is a cutout on the main part at the lower end of the rear wall for cable entry, on the side walls r.for holding the front panel protruding cams and on the front edge of the roof has a labyrinth-like ventilation slot that also serves to hold the upper front panels, are arranged.

Furthermore, it is inventive that on the lower front panel, adjoining the inside at the top, a laterally withdrawn, is arranged with outwardly protruding lugs bar, which are laterally associated with pins.

Outside the dome, it is advisable that!? · Snap into place on the upper front panel in the ventilation slot a strip that leaves a ventilation channel free, laterally engaging elements in the cams and a centrally recessed rotary lock unit arranged are.

In Figure 1, the small distributor is shown in plan.

The small distributor according to the invention consists of one Housing 1 to accommodate the electrical components and the two front panels 2 and 3. All three parts are made of polyurethane foam manufactured and therefore combine the advantages of low weight with extremely high impact resistance and resilience.

DaG polyurethane foam housing 1 is made from one piece, consisting of a base plate, left and right side wall, rear wall and roof. At the lower end of the rear wall, a cutout 4 is provided for the introduction of cables. On both sides, 2 and J> are protruded to hold the two front panels

Cam 5 attached. In the front edge of the roof is a labyrinth-like one Slot 6 is provided, which serves both for ventilation and for holding the front panel 3.

The lower polyurethane foam front panel 2 is hooked into the cams 5 via pins 7 attached in the upper area and placed down against the housing. In doing so, it locks itself automatically via latches attached to the side c. A strip 9 with protruding lugs 10 is formed on the upper edge, which later forms a labyrinth for ventilation in connection with the upper front panel J5.

The upper polyurethane foam front panel 3 comes with a top The molded bar is pushed into the slot 6, then placed against the housing and pushed down against the front panel 2. The retaining locks 11 attached to the side of the front panel snap into the cams 5. By standing up of the locking lever 12 of the locking unit Ij5 prevents the front panel 3 from being removed. To a smooth To reach the outer surface, the lock cover l4 is recessed.

The fact that when the upper front panel 3 is attached, the cams 5 engage on the side walls in recesses 15 under the retaining fasteners 11, and the canton 16 of the lower front panel 2 stand on the inside against the side walls, the same are additionally stiffened advantageously.
