A heat pipe in the sense of the invention is a conventional heat pipe in which a cooling medium within the heat pipe flows back from the cooling area into the evaporation area in a gravity-driven manner after the heating in which it evaporates from an evaporation area into a cooling area. Such a heat pipe is also called thermosyphon, gravitational heat pipe or heat pipe.

The use of such a heat pipe allows a very powerful cooling while taking advantage of very little space. In addition, the shape of such a heat pipe is very well adapted to the structural conditions. The heat pipe according to the invention is L- or U-shaped. In principle, however, it can also be shaped differently, provided that the gravity-driven reflux of the cooling medium is not hindered by the mold. As a mounting rail, a conventional, for example, hat-shaped or C-shaped mounting rail is preferably used. The heat pipe according to the invention is arranged at least partially on one of the support rail facing side of the electrical assembly. Preferably, it lies at least partially on the mounting rail. With this arrangement, it is possible to use the support rail for discharging a part of the heat with. The electrical assembly according to the invention comprises a first housing part, wherein the heat pipe is at least partially disposed on a housing bottom side of the first housing part. It is particularly preferably applied to the underside of the housing at least partially. Most preferably, a groove is provided in the housing underside, in which the heat pipe is inserted. The connection device arrangement according to the invention comprises a thermally conductive plate, in particular made of aluminum or another good thermally conductive material, which is arranged between the heat pipe and the support rail. The plate preferably extends in the direction of the mounting rail. It is particularly preferably at least partly on this. Also in this case, the mounting rail is used to dissipate a portion of the heat. In addition, the plate protects the heat pipe from external influences.

It is also preferred that the heat pipe and / or the plate are electrically conductive, so that the heat pipe can be used as a functional earth for electronics.

In a further preferred embodiment, the electrical module comprises a plurality of module modules, wherein at least one module module comprises a heat pipe. Preferably, the heat pipe and / or the plate are also modularly attachable to the electrical assembly and / or an assembly module of the electrical assembly.

The Fig. 1 shows in (a) a connection device arrangement according to the invention 1 with an electrical assembly 2 and a support rail 4. The support rail 4 is here exemplified U-shaped.

The electrical subassembly 2 has a first housing part 22 on which various electrical connections 31, 32 (the terminal blocks 32 are preferably designed as attachable terminal blocks with conductor connections in, for example, push-in technology, screw connection technology, IDC technology, tension spring technology or the like .) for connecting electrical conductors (not shown) and / or other electrical components (bus - like contacts as terminals 31, further assembly in Fig. 1 not shown) are provided. The assembly 2 is designed like a module and preferably removable and thus exchangeable to the mounting rail 4 fastened so that it can be used as a standalone assembly or in a terminal clamping arrangement or in a series of assemblies 2 (see also Fig. 4 ).

The first housing part 22 has a housing lower side 21 on its side facing the mounting rail 4, and a housing upper side 26 on its side 24 facing away from the mounting rail 4.

Through through openings 28 in the first housing part 22 a plurality of heat pipes 5 can be carried out until they partially rest against the support rail 4 facing the housing bottom 23. For this, the heat pipes 5 are L-shaped here. In Fig. 1 (b) is visible that a groove 211 is provided on the housing bottom 23 for each heat pipe 5, in which the heat pipe 5 can be inserted.

Between the support rail 4 and the voltage applied to the housing bottom 23 parts of the heat pipes 5 is a thermally conductive plate 6 can be optionally arranged, which is made of aluminum here. The plate 6 extends in an extension direction 8 of the mounting rail. It also has for each heat pipe 5 a groove 61 into which the respective heat pipe 5 can be inserted. In an assembled state, the heat pipes 5 and the plate 6 are at least partially on legs 41 of the support rail 4, so that the support rail 4 is shared to dissipate heat.

For fastening the plate 6 to the housing bottom 23 screws 7 are provided here as fastening means. But there are also other fasteners (not shown) such as snaps, rivets or similar usable.

In Fig. 2 It is shown that each heat pipe 5 is provided here for one assembly module 332 in each case. The module modules 332 each have a second housing part 331 (s. Fig. 3 (a) ) and are arranged individually or grouped in a housing pocket 27 of the first housing part 22 to this. For this, the module modules 331 are inserted individually or jointly into an insertion direction 9, which extends transversely to the extension direction 8 of the support rail 4, into its housing pocket 27. In each case a part of a heat pipe 5 is inserted into an assembly module 332. However, embodiments are also conceivable in which a plurality of heat pipes 5 are provided for a module module 332. In addition, embodiments are conceivable in which one or more heat pipes 5 are lined up together with their assembly module 332 to each other.

In the Fig. 3 is visible that each module module 332 for attachment to the first housing part 22 includes a mounting rod 336 which extends in the insertion direction 9, at one end as an actuating means 335 a knob and at the other end as a fastening means 334 T-shaped Anformung formed is. When inserting a module module 332 in its housing pocket 27, the Anformung 334 is inserted through a recess 25 in the upper housing side 26 of the first housing part 22 and rotated by turning the knob 335 so that the Anformung 334 is no longer retractable through the recess 25. For actuating the rotary knob 335, for example, a screwdriver (not shown) can be used.

In the embodiment shown here, a through hole 333 is also provided in the mounting rod 336, on whose side in each case a sensor part of a light barrier 337 is arranged. As long as the module module 332 is not yet attached to the first housing part 22, the light barrier 337 is interrupted. By turning the fixing rod 336, the through-hole 333 is rotated so that a light (not shown) of the light barrier 337 can pass through the through-hole 333 from one sensor part of the light barrier 337 to the other sensor part of the light barrier 337, so that the light barrier 337 is closed. A signal (not shown) of the light barrier 337 is usable by the module module 332, for example by the electronics (not shown) of the module module 332 is activated only when the light barrier 337 is closed and therefore the module module 332 is attached to the first housing part 22. Or a supply voltage of the electronics is interrupted when the light barrier 337 is interrupted. In this case, an electrical connection of the electronics with the light barrier 337 by means of mechanical or electrical means (not shown) can be realized.
