The invention relates to a cover plate for a housing having at least one passage opening for cables, hoses or the like. Lines.

Cover plates of this type are mainly used as a closure lid for housing electrical or electronic switching or control boxes or devices or Hyraulikanschlußstellen use which cover plates to seal the housing and through which cables, hoses or the like. Lines are performed.

To connect the cables or hoses in the appropriate places in the housing, connecting pieces are to be attached at their one ends or cables are soldered directly, for example.

At the other ends, the cables or hoses are often already attached or also carry fittings or switches or the like. Switch elements. Connectors, control switches or the like. Switch elements are also today usually inextricably connected in prefabricated manner with the cables or hoses. Finally, the cables, hoses or the like. Lines in front of their junction also by means of appropriate arrangements, for example, to eliminate a direct train from the outside via the cables, hoses or the like. Cables are clamped to the connection point to have ensured during operation a perfect connection.

This results in the previous training such covering or closure plates insofar disadvantages, as the cable, hoses or the like. Lines each only without connectors, control switches or other components can be performed at their ends by the openings provided in the plates. Prefabricated, inextricably connected at their ends with fittings, switch elements or other components cables or hoses can not be used at all, because an assembly of fittings, switch elements or other, eg electronic, components on the cables or hoses can always only after

Carrying out the cable or tubing through the openings of the usual cover or closure plates done. Soldered cables must be unsoldered, for example, for their replacement and replacement cables or hoses can then be soldered again after their passage through the openings. All components at the ends of the cables, hoses or the like. Lines must usually be removed to allow them to pass through the apertures. In addition, the Sicherungsklemmungen the cables, hoses or the like. Lines are loosened and tightened again.

The object of the invention is now to provide an at least one passage for cables, hoses or the like. Lines having plate for covering a housing, which is formed from parts whose mutually facing side edges are provided with a part of the passage opening recesses, and by means of the indicated disadvantages can be turned off, on the one hand itself easy to install and on the other hand, a particularly simple and little time-consuming installation of cables, hoses or the like. Lines allows.

This object is achieved according to the invention characterized that the plate is constructed in the direction normal to the plate extension of two rigid clamping plates and a permanently elastic sealing plate arranged therebetween and that each clamping plate consists of at least two parts and the sealing plate either analogous to the clamping plates consists of at least two parts or integrally formed and each with one of its outer edge is provided up to the passage opening reaching incision.

The inventive design of the cover makes it possible, even from the outset with fittings (Panzergewindeverschraubung), switch elements or the like. Provided at the ends of cables, hoses or the like. Lines or cables, at the end (s) of an electronic module, a board,

Chip or other electronic component or switch element and the like. already firmly connected or soldered to be able to use. The cables, hoses or the like. Cables do not have to be threaded through the opening of the cover plate, because the parts of the clamping plate and sealing plate can be arranged next to each other, so that the provided on the side edge of the parts, to the entire cross section of an opening complementary recesses cables, hoses or the like. Enclose cables. If the sealing plate is integrally formed, the cables, hoses or the like. Leads through the provided incisions each guided from the outer edge into the passage opening. By fixing the composite cover plate on the housing, eg by locking or by means of fastening screws, the cover plate is compressed in a direction normal to the plane of the plate, wherein the rigid clamping plates squeeze the sealing plate arranged therebetween. The running through the cover plate cables, hoses or the like. Cables so firmly enclosed by the material of the permanently elastic sealing plate, thereby at the same time a clamping of the cables, hoses or the like. Lines done.

According to a further feature of the invention it is provided that the clamping plates are provided at least on one side in the region around the recesses with protruding from the clamping plate level projections, whereby the sealing and clamping effect of the permanently elastic sealing plate in the region of the cable, hose or cable passage is increased , According to the projections are continuous edges.

Thus, when setting the cover plate on the housing, the permanently elastic material of the sealing plate is even more effective against the cover plate passing through cables, hoses or the like. Piping lines, the projections or marginal edges are beveled on the side facing the recess.

According to a further feature of the invention, the part of the clamping plate is formed centrically similar to an axis normal to the clamping plate plane extending, both in manufacturing technology point of view and especially with regard to a

AT 000 447 Ul uncomplicated as possible mountability of the cover plate is of great advantage.

The cover plate according to the invention is particularly suitable for closing of housings for electrical or electronic circuits or controls for operating lifts or cargo areas of trucks. However, the applications of the cover according to the invention are very diverse and by no means limited to the aforementioned field of application.

The object of the invention is explained in more detail with reference to an embodiment in which Fig. 1, a cover plate according to the invention in plan view, Fig. 2, the cover plate according to the invention in section along the line II - II of Fig. 1, Fig. 3, the cover plate in section along the line III - III of FIG.

1, Fig. 4 show a sealing plate and Fig. 5 show two adjacent parts of a clamping plate.

Fig. 1 shows a mounted on a housing wall 1 with a large breakthrough cover plate 2 which is mounted within a frame 3 on the housing wall 1 by means of screws 4 and penetrated by cables 5. The cover plate 2 is formed of an inner stiff clamping plate 6 and an outer rigid clamping plate 7, between which a sealing plate 8 is arranged made of permanently elastic material (Fig. 2 and 3).

Fig. 4 shows the arranged between the clamping plates 6, 7 sealing plate 8, the passage openings 9 has the cable 5 and is provided with holes 10 for the fastening screws 4. In the sealing plate 8, as can be seen also from Fig. 3, cuts 11 are provided which extend from the outer edge 12 of the sealing plate 8 to each passage opening 9 respectively.

In Fig. 5 are two parts 13, 14 of the clamping plates 6, 7 shown, which are each formed centrally similar to a plane normal to the clamping plate plane axis. The parts 13, 14 of the clamping plates 6, 7 are stiff and should be made of solid, stable and low-distortion material, metal or plastic. The parts 13, 14 are provided at their side edges with recesses 15 which are formed in a semi-cylindrical shape and thus form half the cross section of a passage opening 9 for the cable 5. It should be the

Cross section of the passage opening in each case be slightly larger than the cable cross section.

The parts 13, 14 of the clamping plates 6, 7 are provided on one side in the area limiting the recesses 15 with peripheral edges 16 projecting from the clamping plate plane. These are preferably chamfered on the side facing the recess to thereby increase the contact pressure of the elastic material of the sealing plate 8 against the cover plate passing through the cable 5 when tightening by provided in the parts 13, 14 of the clamping plate holes 17 fastening screws. In this way, on the one hand a good seal and on the other hand a sufficient clamping of the cable is achieved. With the tightening of the fastening screws, the sealing plate is also pressed outwards against the housing edge surrounded the cover plate, so that finally an overall excellent sealing of the housing interior is achieved.
