Description

HINGE FOR A SWITCH OR DISTRIBUTION BOX, AND A SWITCH OR DISTRIBUTION BOX

The invention relates to a counter part for a hinge, in particular for a switch or distribution cabinet housing, and a corresponding hinge, in particular a hinge for a low or medium voltage electrical switchgear cabinet comprising a hinge body and such a counter part, wherein the

Hinge body has at least two projecting bolts with passages, in which engages the counter part in the assembled state or in the installed position. Furthermore, the invention also relates to an electrical switching or distribution cabinet, in particular a low or medium voltage switchgear 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.

CONFIRMATION CO. E 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 inappropriate, hinges on

Cabinet housings made of thin sheet to bind, with thin sheet usually has 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 on

Cabinet housing jammed by the bolts passed through two openings in the wall and the counter pin are pressed 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 enter the interior of a Access 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. In the known conical counter pin is disadvantageous that the Einsteckweg 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 way by 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.
