Description

The invention relates to a counter part for a hinge, in particular for an electrical switching or distribution cabinet, and a corresponding hinge, in particular a hinge for an electrical switch or distribution cabinet, comprising a hinge body and such a counter part, wherein the hinge body with at least two projecting pins Passages has. Furthermore, the invention also relates to a switching or distribution cabinet, in particular a low or medium voltage switch or distribution cabinet, with at least one such hinge.

A known control cabinet usually has a cabinet housing which can be closed by at least one door. The respective door is hinged thereto by means of at least one hinge pivotally mounted on a wall of the cabinet housing.

The attachment of a hinge to the wall of a cabinet housing can be realized by numerous different constructive solutions. For example, it has become known to screw a hinge to a wall or to screw it to a wall. It has also become known to lock hinges for fastening or pinning.

A pinned hinge for rotatably mounting a door on the body of a locker or locker is for example from the US 1 410 840 A become known, wherein the pinning takes place by means of two wedge-shaped tapered pins which are inserted into two recesses provided, door and cabinet body by cross-pin of the hinge body.

A to be fastened by screw hinge assembly for the door of a cabinet is from the DE 40 22 079 A1 known. This has a hinged bracket to be attached to a front side of the control cabinet by means of a screw connection and a hinge bracket to be attached in the region of a folded edge leg of the door. The intended to rest on the front of the door front leg of the hinge angle has an inwardly facing pin for passage through an opening formed with excess opening of the door. For fastening the hinge bracket to the door, a clamping bracket is further provided, in the middle part of which there is an opening for a fastening screw, which can be screwed into a corresponding blind hole of the inwardly pointing pin. The legs of the clamp are provided at the edges, each with a sharp-edged projection, which penetrate during assembly in the material of the door and fix it thereby.

However, the known fastening methods are only limited suitable to set a hinge on a modern and lightweight cabinet housing. In particular, some fastening solutions are unsuitable to connect hinges to thin-plate cabinet cabinets, with thin sheet usually having a thickness of 1 mm or less.

The support surfaces for attaching a hinge to a wall or contact surfaces for the hinge are usually very small. Thus, the hinge can support only a small area under load. This is associated with punctual loads, which can deform a relatively thin wall in the area where the hinge is fixed, and can cause lasting damage.

Against this background, arrangements are known in which a hinge is fixed by means of two bolts and a counter-part formed as a counter-pin on a wall. The bolts protrude from the hinge body and each have a transverse bore through which the lock pin is passed.

The hinge consisting of hinge body and counter pin is clamped to the cabinet body by passing the bolts through two openings in the wall and pressing the counter pin into the bolts. The wall is then sandwiched between the hinge body and the counter pin.

Usually, the lock pin is conical. Therefore, the counter pin is in one transverse bore with a higher pressure than in the other. Often the counter pin is under strong pressure in the respective upper transverse bore and with very little play or only little pressure in the respective lower transverse bore.

The consequence of this are different axial forces with which the hinge body is pressed or pressed against the wall of the control cabinet. In this case, additional sealing rings, so-called O-rings, which are placed around the bolts, different degrees of contact with the wall, which leakage problems can occur. In particular, moisture can reach the interior of a control cabinet. The compliance with appropriate protection classes appears due to the occurring leaks so only conditionally guaranteed.

The counter pin usually has so-called paint scratch noses. These scratch the coating of a wall and thus ensure a continuity of a protective conductor connection. at the known conical counter pin is disadvantageous that its insertion is relatively long and visually / aesthetically unsightly scratching grooves remain on the wall.

The invention is therefore an object of the invention to provide a counter part, with which a hinge with a relatively thin wall, in particular a wall of a cabinet housing an electrical switching or distribution cabinet, quickly and easily connectable, with damage to the wall or damage to the wall is largely avoided and the connection ensures high operability. In addition, a hinge with such a counter part and a switch or distribution cabinet should be specified with such a hinge.

According to the invention the above object is achieved by a counter part for a hinge with the features of claim 1, a hinge with such a counter part with the features of claim 11 and a suitably trained switching or distribution cabinet with at least one such hinge having the features of claim 12 , Advantageous embodiments and further developments are specified in further claims and the following description.

The inventively designed counter part for a hinge, in particular a hinge for an electrical switching or distribution cabinet, which hinge has a hinge body with at least two projecting pins with passages, therefore comprises a base body, of which at least two insertion elements for engaging in the passages of the bolts protrude from the hinge body.

Thereafter, the above-mentioned counter part and the respective hinge is characterized in that the counter part has a base body, protrude from which at least two insertion elements, which engage respectively in passages of the bolt.

According to the invention, it has first been recognized that the counter pin known from the prior art, due to its conicity, contributes to an uneven pressing of a hinge body and thus to an uneven load distribution. Furthermore, it has been recognized that, as a result, uneven contact pressure of seals and thus leakage problems are accompanied and can occur.

Advantageously, it has been recognized that these irregularities are overcome when not a single counter-pin, but at least two insertion elements are provided. Despite the possibility that several plug-in elements due to increasing complexity of the counter part favor any irregularities, this approach was taken.

Accordingly, in departure from the state of the art in the article according to the invention at least two insertion elements are provided, which make it possible to distribute the axial force of the bolt evenly. Thus, a uniform contact pressure of the hinge body is achieved on the wall. A relatively thin wall with, for example, a thickness of only 1 mm or less is thus preserved and preserved from deformation and damage.

It is also advantageous to prevent by the application of sealing rings, in particular O-rings, on the bolt penetration of harmful water into a cabinet and thus the required tightness of the cabinet, especially with regard to the respective degree of protection and / or protection class guarantee. In that regard, a hinge is provided, which can be connected quickly and easily with a relatively thin wall, whereby damage to the wall can be avoided and the connection ensures high operability.

Consequently, the object mentioned above is achieved.

Advantageously, the insertion elements of the hinge and in particular the counter part are collinear and arranged one behind the other lying. By this specific embodiment, the insertion elements can be introduced simultaneously into adjacent or in parallel aligned bolts. Thus, the hinge body can be pulled evenly against a wall and / or clamped against these and / or connected to this non-positively.

Further advantageously, the counter part has an elongated base body, to whose longitudinal axis the insertion elements are aligned parallel. By a longitudinal displacement of the body, the insertion elements can be driven into the bolt.

Advantageously, the insertion elements are designed as counter-pins, which are each connected via a connection area with the main body of the counter part. Due to their cylindrical geometry, the counter pins are well guided in the transverse bores and / or passages of the bolts. Furthermore, a screwless fastening of the hinge to a wall is possible.

Advantageously, the insertion elements can have a slightly conical course on or at their free end for easier engagement of the insertion elements in the passages of the bolts.

In a further embodiment, the counter part is advantageously made of zinc die-casting, since this material can easily be machined and machined comparatively accurately and the die casting process with zinc alloys of all casting processes achieves the shortest cycle times and thus an economical production is ensured.

Advantageously, the counter part is also made of plastic manufactured, whereby the hinge can advantageously have a very low weight. Furthermore, a plastic counterpart only scratched a wall to a slight extent when it rubs on the wall and / or comes into contact with it.

Furthermore, it can be provided that the base body has side surfaces on which projections, in particular as paint scratch noses, are provided and arranged, which stand out from the side surfaces. These projections and in particular the paint scratch noses can be formed on opposite side surfaces of the counter part. They realize and / or cause a protective conductor connection of the counter part and / or hinge. If a good protective conductor connection can be proven, a protective conductor connection to the door could also be made from the counter part via an additional hole.

Advantageously, a planar region of the side surfaces is formed above and / or below the projections and / or paint scratch noses. This positioning of the projections and / or paint scratch noses a visible paint damage is covered in the final position of the counter part. The insertion of the counter part is adapted to the extent of the flat areas such that they cover any scratches and / or caused by the hinge assembly damage in the wall when the counter part is in its final position.

Further advantageously, a blocking pin is received in the base body. Through a hole in the counter part of the blocking pin can be inserted. The blocking pin secures the counter part. If the counter part is in an end position, this is locked with the blocking pin. The blocking pin allows the transport of upside-down cabinets over long distances without the counter part being released. Preferably, the blocking pin is made of plastic, but in principle, other materials are providable.

It is furthermore advantageously possible to provide for the main body of the counterpart part to have an F-shaped cross-section. As a result, impact surfaces are formed at two ends of the base body, which can be turned on or hit with a striking tool, in particular a hammer. As a result, the counter part can be fastened as well as loosened, depending on which striking surface is turned on or taken.

The F-shape results further by projecting Anbindebereiche from which protrude the insertion elements, in particular collinear protrude. By a symmetrical design of the counter part, the direction of joining, namely from above, can always be observed when changing the door.

Due to the special shape of the counter part this offers a comparatively large to very large contact surface, which would not be available without additional components available or ready in a conventional screwed or latchable counter part. This large contact surface is suitable for the counter part or allows use of the counter part for an arrangement on walls of thin sheet with a thickness of about one millimeter at most.

Also, the object is achieved by a hinge for an electrical switching or distribution cabinet, which has a hinge body and a pre-described counter part with a base body from which protrude at least two insertion elements, wherein the hinge body has at least two projecting bolts with passages, in which Passages engages the counter part in the assembled state and / or in the installed position with the at least two insertion elements.

Furthermore, the invention also comprises a switching or distribution cabinet, in particular a medium-voltage or low-voltage switchgear cabinet or a medium-voltage or low-voltage distribution cabinet, with a control cabinet housing having at least one door and at least one aforementioned hinge.

The further explanation of the invention and advantageous refinements and developments is based on some embodiments and related figures.
