Abstract
Abstract of the Disclosure A switch cabinet is disclosed which has drawer-type panels of instrument sets adapted to be electrically connected with bus bars disposed inside the switch cabinet. The bus bars are provided, in the area of each drawer-type panel, with a cover which forms a protection upon removal of the drawer-type panel and is adapted to be contacted from below by at least one wedge member on the drawer-type panel to be displaced along the bus bars as the panel is being inserted into the cabinet. The wedge member also serves as a contact piece for establishing ground connection between the drawer-type panel and a side wall, connected to the switch cabinet, of a bus bar channel open toward the face of the switch cabinet.
Description
~066'7~S
This invention relates to a switch cabinet with drawer-type panels of instrument sets adapted to be electrically connected with bus bars disposed inside the switch cabinet. The bus bars are adapted to be covered, when a panel is removed, by means of a cover which, for establishing an electrical contact as the panel is inserted, is adapted to be lifted along the bus bars by means of at least one wedge member which is mounted on the panel.
According to the present invention the wedge member not only lifts the protective cover but also forms a contact for a grounding connection between the drawer-type panel and a side wall, connected with the switch cabinet, of a bus bar channel which is open toward the face of the switch cabinet.
The drawing schematically illustrates one embodiment of the present invention, showing in Figure 1 a switch cabinet in front elevation, Figure 2 a sectional plan view of Figure 1, Figure 3 a side elevation of the wedge member according to Figure
This invention relates to a switch cabinet with drawer-type panels of instrument sets adapted to be electrically connected with bus bars disposed inside the switch cabinet. The bus bars are adapted to be covered, when a panel is removed, by means of a cover which, for establishing an electrical contact as the panel is inserted, is adapted to be lifted along the bus bars by means of at least one wedge member which is mounted on the panel.
According to the present invention the wedge member not only lifts the protective cover but also forms a contact for a grounding connection between the drawer-type panel and a side wall, connected with the switch cabinet, of a bus bar channel which is open toward the face of the switch cabinet.
The drawing schematically illustrates one embodiment of the present invention, showing in Figure 1 a switch cabinet in front elevation, Figure 2 a sectional plan view of Figure 1, Figure 3 a side elevation of the wedge member according to Figure
2.
Figures 1 and 2 illustrate a switch cabinet 1 with a drawer-typ~
panel 2 for instrument sets adapted to be connected in conventional fashion with bus bars 4 disposed inside the switch cabinet 1. In order to simplify the drawing, merely one set, denoted 3, has been shown.
In the area of the drawer-type panel 2, the bus bars 4 are provid-ed with a cover 5 offering a protection from contact with the bus bars 4 after a drawer-type panel 2 has been removed from the switch cabinet 1.
An electrical connection between the instruments 3 and the bus bars 4 is achieved by at least one wedge member 6 on the drawer-type panel 2 extending underneath the cover 5 to lift it along the bus bars 4.
The wedge member 6 is constructed as a contact member for estab- `
. - :
lishing a ground connection between the drawer-type panel 2 and a side wall 7 -~
which is connected with the switch cabinet 1 and forms part of a bus bar 1()66795 channel which is open toward the front of the switch cabinet.
The wedge member is advantageously made from a metal strip which is provided at one end with a rectangularly bent off portion 8 for attaching to the drawer-type panel 2 (Figure 2).
The wedge member is provided at its free end with an inclined edge tFigure 3) which is adapted to extend underneath the cover 5 and lift it.
The wedge member is further provided with sections 10, 11, 12 ormed by means of two longitudinal slits 9 tFigure 3), the sections extending at their respective ends in the plane of the metal strip.
The two outer sections 10, 12 are aligned in approximately cir-cular fashion and disposed outside the plane of the strip. The centre section 11 is likewise removed from the plane of the strip in approximately circular arc-fashion, but in the opposite direction ~Figure 2).
For establishing a ground connection between the switch cabinet 1 and the drawer-type panel 2, the aligned sections 10, 12 of the wedge member 6 abut, in operational position of drawer-type panel 2, the side wall 7 of the bus bar channel. The oppositely directed section 11, however, is permanently in contact with the set 3 of the drawer-type panel 2.
In order to ensure that the side wall 7 of the bus bar channel cannot deviate under the contact pressure of the sections 10, 12 of the wedge member 6, a support sheet 13 on the drawer-type panel 2 (Figures 1 and 2) at approximately the height of the wedge member 6 is provided with an extension or projection 14 tFigure 2) which in operational position of the drawer-type panel 2 forms a support for the side wall 7 of the bus bar channel at the location at which it is acted upon by the wedge member 6. For this purpose, the side wall 7 of the bus bar channel is provided at its front with a bent-off member 15 extending parallel to the face of the switch cabinet. In the bent-off member 15 openings 16 are provided to receive projections 14 in ~ -~
tight-fitting engagc~ont.

panel 2 for instrument sets adapted to be connected in conventional fashion with bus bars 4 disposed inside the switch cabinet 1. In order to simplify the drawing, merely one set, denoted 3, has been shown.
In the area of the drawer-type panel 2, the bus bars 4 are provid-ed with a cover 5 offering a protection from contact with the bus bars 4 after a drawer-type panel 2 has been removed from the switch cabinet 1.
An electrical connection between the instruments 3 and the bus bars 4 is achieved by at least one wedge member 6 on the drawer-type panel 2 extending underneath the cover 5 to lift it along the bus bars 4.

which is connected with the switch cabinet 1 and forms part of a bus bar 1()66795 channel which is open toward the front of the switch cabinet.
The wedge member is advantageously made from a metal strip which is provided at one end with a rectangularly bent off portion 8 for attaching to the drawer-type panel 2 (Figure 2).
The wedge member is provided at its free end with an inclined edge tFigure 3) which is adapted to extend underneath the cover 5 and lift it.
The wedge member is further provided with sections 10, 11, 12 ormed by means of two longitudinal slits 9 tFigure 3), the sections extending at their respective ends in the plane of the metal strip.
The two outer sections 10, 12 are aligned in approximately cir-cular fashion and disposed outside the plane of the strip. The centre section 11 is likewise removed from the plane of the strip in approximately circular arc-fashion, but in the opposite direction ~Figure 2).
For establishing a ground connection between the switch cabinet 1 and the drawer-type panel 2, the aligned sections 10, 12 of the wedge member 6 abut, in operational position of drawer-type panel 2, the side wall 7 of the bus bar channel. The oppositely directed section 11, however, is permanently in contact with the set 3 of the drawer-type panel 2.
In order to ensure that the side wall 7 of the bus bar channel cannot deviate under the contact pressure of the sections 10, 12 of the wedge member 6, a support sheet 13 on the drawer-type panel 2 (Figures 1 and 2) at approximately the height of the wedge member 6 is provided with an extension or projection 14 tFigure 2) which in operational position of the drawer-type panel 2 forms a support for the side wall 7 of the bus bar channel at the location at which it is acted upon by the wedge member 6. For this purpose, the side wall 7 of the bus bar channel is provided at its front with a bent-off member 15 extending parallel to the face of the switch cabinet. In the bent-off member 15 openings 16 are provided to receive projections 14 in ~ -~
tight-fitting engagc~ont.
