Out 1 is a module cassette housing 10 for superposed connection techniques 43 for inclusion in a distributor field frame, not shown. The module cassette housing 10 has a walls having lower housing half 20 with a connecting edge 21 and an opening edge 22 and one on the lower half of the housing 20 attachable, wall-mounted upper housing half 30 with a connecting edge 31 on. Furthermore, it can be seen that the lower half of the housing 20 and the upper half of the housing 30 a circuit board sandwich 40 comprising a first circuit board 41 with connection techniques 43 and a second circuit board 42 with bushes 43 encloses.

The side walls 23 the lower half of the housing 20 each have a first bridge embossing 24 at a distance and parallel to the opening edge 22 as a stop for the external joining techniques 43 the second circuit board 42 on. In addition to these first bridge embossments 24 have the side walls 23 the lower half of the housing 20 each a second bridge embossing 25 at a distance and parallel to the connecting edge 21 as a support for the first circuit board 41 of the circuit board sandwich 40 on. This is how the circuit board sandwich becomes 40 through the first bridge embossments 24 and the second bridge embossments 25 inside the lower half of the housing 20 positioned.

The side walls 33 the upper half of the housing 30 each have a second bridge embossing 35 at a distance and parallel to the connecting edge 31 the upper half of the housing 30 on. This is how the circuit board sandwich becomes 40 when attaching the upper half of the housing 30 on the lower half of the housing 20 between the second bridge embossing 25 the respective side wall 23 the lower half of the housing 20 and the second bridge embossing 35 the respective side wall 33 the upper half of the housing 30 fixed.

Furthermore, the side walls 33 the upper half of the housing 30 one nose contour each 36 on, which are designed such that when attaching the upper half of the housing 30 on the lower half of the housing 20 the respective nose contour 36 in the corresponding first bridge embossing 24 the respective sidewall 23 the lower half of the housing 20 intervention. In this way, the upper half of the housing 30 positively with the lower half of the housing 20 connected.

At this point it should be mentioned that the first bridge embossing 24 the respective side wall 23 the lower half of the housing 20 also a nose contour 24 ' can be and the nose contour 36 the respective side wall 33 the upper half of the housing 30 a first bridge embossing 36 ' ,

In order to reduce vertical play of the attached upper half of the housing to the lower half of the housing, has the respective side wall 33 the upper half of the housing 30 and the respective side wall 23 the lower half of the housing 20 one projection each 60 and one return each 61 on, wherein when attaching the upper half of the housing 30 on the lower half of the housing ( 20 ) the respective lead 60 the side walls 33 the upper half of the housing 30 in the corresponding return 61 the side walls 23 the lower half of the housing 20 engages and the respective lead 60 the side walls 23 the lower half of the housing 20 in the corresponding return 61 the side walls 33 the upper half of the housing 30 ,

The respective side walls 23 the lower half of the housing 20 continue to each have a material recess 26 for holding a strap 50 on. The coat hanger 50 will be between the joining techniques 43 the first circuit board 41 and the connection techniques 43 the second circuit board 42 positioned. In this way, on the one hand, the gap between the first circuit board 41 and the second circuit board 42 locked. On the other hand, there is an additional fixation of the printed circuit board sandwich in the field of connection techniques.

Like from the 2 can be seen, the lower half of the housing 20 next to the first bridge embossing 24 in the respective side walls 23 a first bridge embossing 24 in the bottom wall 27 as a stop for the in 1 apparent connection technology 43 the first circuit board 41 on. It can also be seen that the first bridge embossing 24 the respective side wall 23 at right angles to the connecting edge 21 is arranged. In this way, when attaching the upper half of the housing 30 on the lower half of the housing 20 by a relative displacement of the upper half of the housing 30 to the lower half of the housing 20 the nose contour 36 the respective side wall 33 the upper half of the housing 30 in the corresponding first bridge embossing 24 the respective side wall 23 the lower half of the housing 20 one.

Furthermore, the lower half of the housing 20 each in the bend edge between the bottom wall 27 and side wall 23 an elongated slot 28 in the longitudinal direction of the bending edge for laterally positioning the lower half of the housing 20 in the distributor field frame, not shown. In this way, the module cassette housing 10 be positioned securely in the distribution field frame.

Of the 3 is removable, that the two side walls 33 the upper half of the housing 30 each a second bridge embossing 25 and one nose contour each 36 exhibit. The second bridge embossing 25 serves to fix the printed circuit board sandwich 40 when attaching the upper half of the housing 30 on the lower half of the housing 20 and the nose contour 36 a positive connection of the upper half of the housing 30 with the lower half of the housing 20 ,

Again 4 removable, is the upper half of the housing 30 on the lower half of the housing 20 plugged, causing the circuit board sandwich 40 between the second bridge embossing 25 the lower half of the housing 20 and the second bridge embossing of 35 the upper half of the housing 30 is fixed. In addition, the nose contour attacks 36 the respective side wall 33 the upper half of the housing 30 in the first bridge embossing 24 the corresponding side wall 23 the lower half of the housing 20 , whereby the upper half of the housing 30 positively with the lower half of the housing 20 is connected. The on the lower half of the housing 20 attachable straps 50 closes the gap between the joining techniques 43 the first circuit board 41 and the connection techniques 43 the second circuit board 42 and gives the system an extra grip.
