Description

The invention relates to a through-mounted housing according to the restrictive part of the independent paragraph 1 of the claims.

Feed-through housings of this kind are required in order to carry lines or cables from one enclosed area to another area and vice versa.

BACKGROUND OF THE INVENTION

EP 2 845 277 A2 shows a feed-through housing that is located on an electrical component. The feed-through housing consists of a lower housing and an upper housing. Recesses are provided in the lower part of the housing, in which several cable feed-through seals are located for cable routing. The direction of cable entry and the direction of cable exit form an angle of more than 90° to each other with this feed-through housing. This arrangement requires a lot of space. Each cable has its own notch, so the number of cables required must be agreed and known in advance. As a result, the feed-through housing cannot be universally used for all components or devices.

US 2016/241007 A1 shows an electrical assembly for installation in a building structure for power distribution and telecommunications.

DE 20 2010 008 934 U1 shows a connection device intended for installation on the outer surface of an electrical device, with an outer housing consisting of a main housing with a base and a housing cover, while it is provided with a recess for connecting the first electrical unit located below the outer surface .

However, these known feed-through housings cannot be universally used either.

FORMULATION OF THE PROBLEM

The object of the invention is to provide a versatile and compact feed-through housing.

The problem is solved using the object of the independent paragraph 1 of the claims.

Preferred embodiments of the invention are indicated in the dependent claims.

The bushing according to the invention is used for carrying one or more lines and/or cables out of or into a closed area. In this case, the closed area has a barrier, which has at least one wall, on which the feed-through housing can be mounted. Speaking of lines, we can talk, for example, about conductive conductors with a large cross section. However, pneumatic lines or optical fibers are also equally possible. Speaking of cables, we can talk about, for example, multi-core cables. The invention is not limited to the type of lines or cables. Where appropriate, the terms lines and cables are also used interchangeably within the scope of this application.

A through-mounted housing consists of a housing body and a corresponding housing cover. “Conforming” means in this sense that the body of the housing is completely covered by the housing cover, and the feed-through housing encloses an empty space shielded from the rest of the environment. The cover of the housing is removable and can be reversibly attached to the body of the housing using anti-lost fasteners. The cover of the housing in the removed state allows convenient access to the opening for the opening and the outlet inside the body of the housing. The housing cover is made in the form of a cap and is designed in such a way that both the opening under the opening and the outlet or outlets are easily accessible by hand.

The housing body has an opening for the opening and at least one outlet. The opening under the opening correlates, as a rule, with the opening into the closed area. In this case, the restricted area refers to the wagon of the rail vehicle or the rail vehicle itself. The opening is in this case on the wall of the wagon or rail vehicle. By means of the two feed-through housings according to the invention, two cars can accordingly be connected to each other in a manner capable of transmitting current and data.

The plane in which the opening under the opening is located and the plane in which the outlet is located are oriented essentially perpendicular to each other. This arrangement allows the most compact installation of lines or cables within the feed-through enclosure.

Preferably, the housing body has exactly one opening for the opening and exactly two exit openings. Lines or cables entering through the opening under the opening into the feed-through housing can be distributed inside the feed-through housing through both outlets. In this case, the feed-through housing acts as a so-called Y-distributor. The lines and/or cables entering the feed-through housing are arranged approximately perpendicular to the lines and/or cables connected to the feed-through housing (via plug-in connectors).

Preferably, the planes of the outlets are oriented parallel to each other and spaced vertically apart. If the feed-through housing is mounted on the wall, then we can say that the outlets are offset sideways from each other, that is, they are removed at different distances from the wall. The outlet located further from the wall is located above the outlet located closer to the wall. Preferably, the planes of the outlet openings are oriented in each case essentially perpendicular to the opening under the opening. This arrangement proved to be the most compact and space-saving.

In the most preferred embodiment of the invention, the housing body has on its outer side along the opening for the opening a groove extending along the perimeter. The groove is provided to accommodate the seal and seal the wall-side through-hole housing.

Preferably, the feed-through housing has holes for wall mounting. The through-hole housing can be screwed onto a wall, for example. Preferably, these openings are provided both on the housing body and on the housing cover. In order to remove the housing cover, the screws on the housing cover must first be removed. The openings of the housing cover in this case additionally take on the function of interlocking between the body of the housing and the housing cover.

Preferably, the through-mount housing is made of metal. As a result, the shielding properties of the feed-through housing are increased, in particular against electromagnetic fields. The feed-through housing is at least partially provided with a lacquer coating. The lacquer coating serves in particular to protect against corrosion, but it also contributes to its modern and streamlined design.

In the most preferred embodiment of the invention, the body of the body of the through-mounted housing does not have a groove between the groove running along the perimeter and the opening under the varnish coating opening. In this case, the feed-through housing is only partially varnished, i.e. not fully varnished. The area between the groove running along the perimeter and the opening for the opening is in a screwed state in direct contact with the wall. In the case of a metal wall, a conductive connection can therefore be established between the feed-through housing and the wall, which entails advantages with regard to grounding.

Most preferably, the feed-through housing has fastening means for securing the holding frame of the plug connector modular system and/or the plug connector itself. Retaining frames are known, for example, from EP 0 860 906 B1. As a rule, holding frames are equipped with the same and/or different plug connector modules. The holding frames serve in this way to receive several identical and/or also different plug-in connector modules and securely fix them in the feed-through housing.

To secure the holding frames, the through-mounted body has threaded holes in the area of the outlets, with which the holding frame can be fixed inside the outlet. The outlet opening, together with a retaining frame equipped with plug connector modules, constitutes a connection socket for a plug connector.

Plug-in connector modules generally have in each case a substantially parallelepipedal insulating body or a parallelepipedal housing. These insulating bodies or housings can serve, for example, as contact holders and receive and fix various types of contacts. The purpose of the plug connector thus formed is thus very flexible. For example, pneumatic modules, optical modules, modules for transmitting electrical energy and/or electrical analog and/or digital signals can be housed in a suitable insulating body or housing and thus used in a modular plug connector system. Connector modules are increasingly also taking over the tasks of measuring and transmitting data.

However, it is also possible to fix one-piece plug connectors, in particular plug connectors for the transmission of high currents, in the feed-through housing. The plug connectors also snap into place in the region of the outlet and in this case form the connection point for the mating plug connector. Such a plug connector is presented, for example, in DE 10 2011 001 064 B3.

An exemplary embodiment of the invention is shown in the drawing and is explained in more detail in the following. The drawing shows:

fig. 1 is a perspective view of a feed-through housing according to the invention;

fig. 2 is a plan view of the rear side of the feed-through housing according to the invention;

fig. 3 is a plan view of the front side of the feed-through housing according to the invention;

fig. 5 is a further perspective view of the body of the feed-through housing according to the invention;

fig. 6 is a perspective view of the lid of the feed-through housing according to the invention;

fig. 7 is a further perspective view of the lid of the through-hole housing according to the invention;

fig. 8 is a perspective view of a feed-through housing according to the invention into which two plug connectors are inserted; and

fig. 9 is a further perspective view of a feed-through housing according to the invention into which two plug connectors are inserted.

The figures contain partially simplified, schematic representations. Partially identical but possibly non-identical elements use identical reference numbers. Different views of the same elements can be scaled differently.

Fig. 1 to 3 show in each case a through-mounted housing 1 according to the invention. The feed-through housing 1 is generally used in the railway field and serves to connect two zones, usually two cars, to each other in a way that allows current and signals to flow. The feed-through housing 1 consists of two parts and has a housing body 2 and a corresponding convex housing cover 3. The through-mount body 1 has holes 4 for fixing the through-mount body 1 on the car wall (not shown for illustrative reasons).

The housing 1 through-mounting has a substantially rectangular hole 5 under the opening. The opening 5 under the opening can be seen in the top view in FIG. 2. The feed-through housing 1 is directed by the opening 5 under the opening to the aforementioned wall and correlates there with the opening in the wall. The feed-through body 1 has two essentially rectangular outlet openings 6. The plane in which the opening opening 5 is located under the opening and the plane in which the outlet openings 6, 6' are located in each case are perpendicular to each other.

The lines and/or cables located in the same zone are inserted in the direction E of the entrance into the opening 5 under the opening. There, the lines and/or cables are connected to plug connector modules (not shown) and/or plug connectors (not shown) which are located in the region of the outlets 6 inside the body 2 of the housing. Here they form a connection possibility for plug-in connectors 7, which are inserted into the feed-through housing 1 so that currents and/or line and/or cable signals leave the feed-through housing 1 in the output direction A. Plug-in connectors 7 are reversibly fixed with retaining clips 8 on housing 1 through-hole installation. The inlet direction E and the outlet direction A are arranged in the same way as the aforementioned planes of the opening opening 5 and the outlet openings 6, 6', perpendicular to each other.

In FIG. 6 and 7 the feed-through housing cover 3 is shown in each case in perspective. The special shape of the housing cover cap 3 makes it possible to provide a spacious access opening 12 which provides ample space for mounting or cable routing.

In FIG. 4 and 5 the body 2 of the feed-through housing 1 is shown in perspective without the cover 3 of the housing. If the housing cover 3 is removed from the through-mounted housing 1, then the fitter can easily access the opening under the opening and the cables and/or lines that pass through it. It can connect lines and/or cables respectively to plug connector modules and/or plug connectors and fix the latter in the region of the outlets 6, 6'. For this, threaded holes 10, 10' are provided in the region of the outlets 6, 6'. In the housing body 2, holes 9 are provided along the access hole 12, which correlate with the threaded holes 11 of the housing cover 3. As a result, the housing cover 3 can be securely and reversibly attached to the housing body 2 .

The outlets 6, 6' are spaced apart in the vertical direction. The lower outlet 6 is located closer to the wall. The top outlet 6' is further away from the wall. This arrangement also increases the ease of installation of the through-mounted housing 1 . Both outlets 6, 6' are easily accessible for connecting lines and/or cables.

Around the opening 5 under the opening, the housing body 2 has a groove 13 extending along the perimeter. A seal is placed in the groove 13 in order to seal the corresponding openings or openings of the wall and the through-mounted housing 1 from the penetration of media.

Housing 1 through-hole is almost completely varnished. Only the hull body 2 has an unlacquered area 14 . The unlacquered area 14 is located between the perimeter groove 13 and the opening 5 under the opening, as can be seen in FIG. 2 and 8.

Although in the figures various aspects or features of the invention are shown in each case in combination, it will be understood by those skilled in the art - unless otherwise indicated - that the combinations depicted and discussed are not the only possible ones. In particular, blocks or combinations of features corresponding to each other from different embodiments can be interchanged with each other.
