a perspective view of the other half of the cross-cut H-piece of Fig. 1 to 3 with assembled housing halves.

The FIG. 1 shows a distribution piece, more precisely H-piece, formed distribution device 10 with four line and / or terminal devices 12. Each of the line and / or terminal devices 12 is formed as a plug connection 14 and has a guided in a plug insert set of line elements 16. Furthermore, each of the line and / or connection devices 12 has a shielding device 18 designed as a shielding sleeve. Between the line and / or terminal devices 12 is located within a housing 20 of the distributor device (10) of this housing 20 and the line and / or terminal devices 12 housed interior 22 of the manifold 10. On each of the sides of the H-piece trained distribution device 10 is a plug-in connection pair, each with two mutually parallel plug-in terminals 14 are arranged. Each of the plug connections 14 of one of the two plug connection pairs is arranged coaxially with a corresponding plug connection 14 of the other plug connection pair on the opposite side of the distribution device 10. By this arrangement and extending over the full width of the page interior 22 of the manifold 10 results in the characteristic H-shape of the H-piece.

In the middle part 24 with the interior 22 of the distributor device 10, two conductor track carriers 26, 28 arranged parallel to one another and extending over the width are arranged. These are both designed as rigid printed circuit boards. One of the conductor carrier 26 is the one plug-in connection pair, the other of the conductor carrier associated with the other plug connection pair. In each of the conductor carrier 26, 28 pins and / or sleeves 30 for contacting the respective conductor carrier 26, 28 with the associated line and / or terminal devices 12 and the two conductor carrier 26, 28 are pressed together.

The Fig. 2 shows the corresponding situation in a cut page presentation. The part of the sleeves 30, which serve to contact the line element sets 16 of the individual line and / or connection devices 12, are connected to the individual line elements. The conductor track carriers 26, 28 have conductor tracks (not shown here) for interconnecting the line element sets 16 of the different line and / or connection devices 12 with one another.

The housing 20 is formed by two housing parts 36, 38 formed as housing halves 32, 34. The two housing halves 32, 34 are formed as housing half-shells, which engage over the interior 22 with the conductor track carriers 26, 28 in the assembled state fully (360 °). The distributor device 10 furthermore has two contact elements 40, 42 which rigidly connect to one another and electrically contact the two conductor track carriers 26, 28. Both contact elements 40, 42 are as with their respective end portions in the one conductor carrier 26 and in the other conductor track carrier 28 pressed cylindrical contact pins 44, 45 are formed.

Each of the housing halves 32, 34 has on its respective inner side a structure 46, 48, wherein each of the structures 46, 48 has two contact projections 50, 52. Each of the structures 46, 48 is formed as a U-shaped structure formed as elastic legs of the U-shape contact projections 50, 52.

Furthermore, each of the housing halves 32, 34 has a clamping device 54, 56, each with two spaced-apart clamping jaws 58, 60. The corresponding distance A between the inner legs of the clamping jaws 58, 60 corresponds approximately to the outer distance between the two trained as elastic leg contact projections 50, 52 of the structure 46, 48 of the other housing halves 32, 34. Each of the jaws 58, 60 has on its inside a run-up slope 62, 64 so that the distance of the jaws at the bottom of the respective clamping device 54, 56 is smaller than the distance between the end regions of the clamping jaws 58, 60th

Each of the housing halves 32, 34 furthermore has a guide device 66, 68 for guiding the housing parts during assembly.

This results in the following function: If the line and / or connection devices 12 are connected to the respective strip conductor carriers 26, 28 and contacted with one another via the contact elements 40, 42 which are in the form of contact pins 44, 45, then the conductor track carriers 26, 28 are placed in one of the Housing halves 32, 34 inserted. In this case, the substantially U-shaped structure 46 of the one housing half 32 overlaps the one contact element 40, so that this is arranged with one of its sections between the formed as an elastic leg contact projections 50, 52. The second contact element 42 is located in the region of the clamping device 58 of the first housing half 32.

Fig. 3 shows the corresponding situation. If the second housing half 34 is placed, ie the two housing parts assembled, the clamping device 56 of the second housing half 34 engages over the ends of the contact projections 50, 52 of the U-shaped structure 46 of the first housing half 32 and jammed thereby by the assembly by means of the chamfers 62nd , 64 increasing pressure, the corresponding contact projections 50, 52 of the structure 46 with the first contact element 40th

The same thing happens with the second contact element 42. Here, the clamping jaws 58, 60 of the clamping device 54 of the first housing half 32 overlap the ends of the contact projections 50, 52 of the second structure 48 of the second housing half 34 and jam by increasing with the assembly pressure through the ramps 62, 64 the elastic contact projections 50, 52 with the contact element 42. The corresponding situation is with regard to the other side of the distribution device 10 in FIG Fig. 4 displayed.

In the in the Fig. 1 to 4 distributor device 10 thus shown, the electrically conductive housing 20, consisting of the housing halves 32, 34 easily and safely connected to the conductor track carrier 26, 28 with the shielding devices of the plug-in connections 12. Due to the jamming of contact projections 50, 52 and contact elements 40, 42, both housing halves 32, 34 are securely contacted.

At least one of the housing parts 36, 38, that is to say the housing halves 32, 34, has an opening through which the conductor track carriers 26, 28 in the interior 22 of the distributor device 10 are encapsulated with electrically insulating material after the housing parts 36, 38 have been assembled.

By the two conductive housing halves 32, 34, which may be formed the same, thus an EMC shielding is realized. This shield of the distribution device 10 can be combined with both plug-in connections and with shielded lines. The interconnection inside the distributor device 10 is completely encapsulated. Thus, the shielding can optionally be integrated into the interconnection.
