Abstract
Abstract of the Disclosure The invention relates to a switch cabinet for equipment modules, each of which carries a wedge. When its carrier is pushed into the switch cabinet, the wedge is adapted to be engaged under a busbar cover and to be lifted along the busbars. The busbar cover is arranged between a duct baffle and the busbars. Furthermore, the busbar cover, when lifted, exposes an aperture located under the duct baffle, through which aperture the wedge and contact parts of the equipment module are adapted to be inserted into the busbar duct.
Description
~0667~
The in~ention relates to switch cabinets for equipment modules or slide-in units A switch cabinet for equipment modules, each of which carries at least one wedge adapted, when the module or unit is slid into the cabinet, to engage under a busbar cover and to be lifted along busbars, is already known.
In this cabinet, the busbar cover is in the form of tubes surrounding a busbar and connectod together by means of webs (German Utility Model 7,515,974).
It is the purposo of the invention to design a switch cabinet of tho typo mentionod in a mannor such that the busbars are protectet more than horotoforo against inadvertent contact, In this case, the busbar cover is of simple dosign and is adapted to be ~nstalled and removod, ovon when the bus-bars aro already mounted in the switch cabinet.
Accordingly the apparatus of the invention consists of a switch cabinet for oquipment modules, slide-in units and the like, each of which ~ -carries at least one wedge adapted, when the module or unit is slid into the cabinot, to engage under a busbar covor and to be liftod along busbars, said cabinet comprising a busbar duct having a stationary duct baffle, busbars mountod in said tuct, a liftable busbar cover in said duct between said baffle and a front face of said busbars, and an aporture located beneath said duct bafflo, wherein said aperturo is exposed or openet when the busbar cover is liftod and said wedge and eontaet parts of the module or unit can be inserted into the duct when said aporture is exposed or open.
An oxa~plo of a preferred embodimont of the invention is illustrated diagra~matically in the drawing attached hereto, wherein:
Piguro 1 is a front viow of an opon switch cabinet;
Figure 2 is a soction along the section line II - II in Figure l;
and Pigure 3 is a section along the section line III - III in Figure 2.

Each of the equipment modules carries a wedge 2 which in Pigure 2 --is shown in two different positions in dotted lines. When its carrier is pushed into the switch cabinet, the wedge 2 is adapted to engage under a bus-bar cover 3 and to be lifted along the busbar 4 (~igure 2).
Busbar cover 3 is arranged in a busbar duct having walls 5. (See Figure 3). The cover 3 is between a stationary duct baffle 6 and the front side of the busbars 4.
Purthermoro, the busbar covor 3, when liftod, oxposes an aperture 7 locatot under the duct baffle 6, through which the wedge 2 and contact parts tnot shown) of tho oquipment module are adapted to be inserted tFigures 1 and

Each of the equipment modules carries a wedge 2 which in Pigure 2 --is shown in two different positions in dotted lines. When its carrier is pushed into the switch cabinet, the wedge 2 is adapted to engage under a bus-bar cover 3 and to be lifted along the busbar 4 (~igure 2).
Busbar cover 3 is arranged in a busbar duct having walls 5. (See Figure 3). The cover 3 is between a stationary duct baffle 6 and the front side of the busbars 4.
Purthermoro, the busbar covor 3, when liftod, oxposes an aperture 7 locatot under the duct baffle 6, through which the wedge 2 and contact parts tnot shown) of tho oquipment module are adapted to be inserted tFigures 1 and
2).
The busbar cover 3 is displaceable between two busbar retainers 8 secured in the busbar duct at a distance apart of ono modulo ~See Pigure 2).
The busbar retainers in tho example illustrated are in the form of sheets of insulating material equippod with lugs 9 passing through the walls 5 of the busbars tSee Piguro 3).
In the example illustratod, the busbar cover 3 is also U-shaped, the web boing roundod off for the wedge 2 to engage thereunder ~Figure 2).
This U-shape is a great advantage, since the legs thereof provide double secu-rity against contact with busbars 4. Purthermore, the lateral defining sur-facos of the logs provide a wide support for walls 5 of the busbar duct.
