Description

Description

The invention relates to a wall housing for accommodating passive and/or active electrical and/or electronic components or plug-in units, in particular network components of communications and data processing technology.

Wall-mounted enclosures are usually manufactured as one-piece enclosures with a door or as a frame with attached wall sections and door, as well as base and cover sections. The aim is to ensure that the connection points of the built-in components or inserts that protrude into the interior are easily accessible during assembly so that cabling can be carried out easily and reliably.

It is known to insert a second frame for the built-in components into the housing in order to ensure good accessibility of the wiring levels, which can be rotated for assembly and thus makes the wiring level accessible from the door side (DE-GM 295 17 954 U1). It is also known to place this additional frame on rails so that it can be pulled out of the housing for assembly (DE-PS 198 11 743 C1).

The disadvantage of these solutions is that the second frame wastes space in the housing and results in additional manufacturing costs. Another disadvantage is that the cables for the internal wiring move with the inner frame and therefore have to be longer than their intended use requires.

In addition, the movement creates uncertainties for the cabling.

It is also known to design the side walls as doors (DE-OS 198 17 245 A1), so that accessibility can be ensured from all sides, or to connect the front door to a side part that is also attached to hinges (DE-GM 298 18 634 LM), which easily ensures accessibility from one side.

Of course, these solutions are also more expensive than using simple integrated or fixed wall parts.

A cabinet accessible from all sides uses a simple frame to accommodate 19-inch components, to which the base and cover are attached, while all side panels and the door can be removed separately (DE-GM 299 10

The problem with this cabinet is its stability.

The problem of the invention is to avoid the disadvantages of known cabinets. In addition, the cabinet according to the invention should allow the installation of 10-inch components and a high packing density in addition to the installation of 19-inch components.

The problem is solved according to the invention by a cabinet having the features of the characterizing part of the main claim.

Useful embodiments or variants arise from the subclaims.

It is particularly advantageous that both 19-inch wide components and optionally 10-inch wide components can be installed or inserted into the cabinet according to the invention. If the configuration is chosen sensibly, a high packing density is achieved in the cabinet. The ability to open three sides of the cabinet ensures good accessibility to the wiring levels during assembly. Short cables can be used and the stability of the cabinet is very high.

It can be produced inexpensively.

The invention is explained in more detail below using an embodiment.

The wall cabinet according to Figure 1 consists of a frame 17 (see Figure 2), an upper part 1 attached to it, which is partially provided with ventilation openings 2, a removable left wall element 3, a right wall element 4 which is a mirror image of it (see Figure 4), a base part 6 attached to the frame and a rear wall 5 with perforated grommets 7 for wall attachment.

The wall cupboard can be closed with a door 13 (see Figure 4), not visible in the picture, opposite the rear wall.

Figure 2 shows the same cabinet from the front with the right side panel and door removed.

Within the right side, hole profiles 8.1 (top) and 8.2 (bottom) and within the left side, hole profiles 9.1 (top) and 9.2 (bottom) are attached to the frame 17.

The holes for attaching components in both profile pairs are spaced 19 inches apart. The existing perforated rails thus enable the vertical installation of 19-inch components from the sides.

One possible configuration is, for example, that several components are inserted from the right into the front half of the cabinet and the space remaining in the depth

by inserting it from the left side. The rear sides of the built-in units intended for cabling are accessible from the left and right side of the wall and from the front.

Another possibility is full assembly from the right and left if the built-in components have only a small depth.

Figure 3 shows the same wall housing equipped at the front with vertical perforated rails 10.1 (left) and 10.2 (right), with the hole spacing of both rails being 10 inches.

This makes it possible to install several 10-inch components horizontally from the front.

The right side is equipped with perforated rails at 19 inch intervals as in Figure 2, so that 19 inch components can be inserted into the free space. A mixed 10 inch/19 inch configuration is therefore possible, whereby the available space can be used to the maximum.

Other customer-specific configurations not shown can be implemented by exchanging perforated rails, depending on the required components and the practicality of the arrangement of the control elements: only 10-inch components or 19-inch components from the front and 10-inch components from the

Figure 4 shows a cabinet with the right side wall 4 and the door 13 removed. As can be seen on the side wall 4, the side walls can be easily pulled out to the front after the door has been removed, so that rapid access to the interior of the cabinet and the wiring levels of the built-in components is ensured.

After the side wall has been pushed in, pins 11 engage through holes 12 in tabs on the side wall and stabilize it at the back. When the door is closed, this covers a front fold 14 on the side wall and stabilizes it at the front.

Figure 5 shows different designs of the door 12, which can also be used for the side walls.

The cheapest option is a door made only of sheet metal according to variant a.

If there are reading elements (instruments, LCD displays, LEDs) on the built-in components, variant b with glass pane 15 is recommended. The door does not have to be opened for reading.

If a lot of heat is generated inside the cabinet, we recommend door variant c with air slots 16.

If necessary, the side panels can also be equipped with fans.
