A head or bottom element of a component support, having guide rails arranged side-by-side and aligned in an insertion direction for receiving a printed circuit board of a plug-in module, wherein the guide rails are formed by one-piece guide elements of the head or bottom element. The guide elements can be formed of two rows of several guide strips per guide rail, each of which extends in the insertion direction, which strips are punched out of a plate-shaped head or bottom element and are projectingly beveled in the direction toward an underside of the head element or a top of the bottom element. A distance of the guide strips of the guide rails is matched to the thickness of the printed circuit boards of the plug-in modules. The head or bottom element forms guide paths for the printed circuit boards of the plug-in modules between the rows of guide strips of the guide rails. The production of the head or bottom element is not only simplified, but is also made cheaper, and furthermore the possibility of contacting the head or bottom element with the printed circuit boards is increased.

Head or bottom element of a component support

A device for detachable electrical connection of a contact pin to a sheet metal component. According to this invention, a durable conducting connection of the contact pin to the sheet metal component may be achieved, whereby the sheet metal component has at least one perforation, in which a sleeve for a contact element is housed in an electrically-conducting manner, enclosing a spring element. The contact pin is housed in the sleeve by the spring element in the assembled position and the contact pin and the sleeve are electrically connected to the sheet metal component by the spring element. This arrangement has a particularly high current-carrying capacity as a result of the spring arrangement housed in the sleeve.

A component support having two or more module carriers aligned with each other in a direction across a width of a component support. The module carriers have two insert card guidance devices connected with each other via a support element so that guides of the insert card guidance devices, which extend in the direction of the depth of the component support, form receivers for one or several insert cards. The insert cards are electrically connected to a rear support by plug-in connections, and the module carriers are releasably connected with the support so that the removal of a single arbitrary module carrier from the row of the module carriers is possible. The component can be individually matched in a simple manner to different applications.

Component support

A component support having at least one insert card reception chamber with two insert card guidance devices, which have oppositely located guides for receiving at least one insert card. The guides are arranged and spaced apart from each other by a size of a height of the insert card. Insert cards of different structural height can be installed in the component support if the insert card receptacle is divided at a half of the height between the two guides by a guide rail. The guide rails, together with the guides of the insert card guidance devices, form partial receptacles, into which printed circuit boards of a reduced insert card height can be introduced.

An operating element having an end piece, which is arranged for connecting to a printed circuit board and a front plate. An operating lever is rotatably mounted on the end piece. The operating lever has at least one grip section and one on and/or off lever piece, which are at least partly made from a wear-resistant material. Such a design has the particular advantage that part of the operating element which performs an on and/or off lever action, the on and/or off lever piece, opposite the section of the operating element to manipulate, the handle, is at least partly made from a wear-resistant material. The complete unit is thus rendered significantly more robust without sacrificing ergonomics of the grip piece.

A contact assembly having a spring contact strip and a contact element, in particular, a subrack front panel. The spring contact strip has a contact limb that is bent over, with an end that can be freely pivoted. To improve the mechanical stability of the spring contact strip, the inventive contact limb extends an entire length of the spring contact strip.

Electric contact assembly

The mounting rack (BGT) has plug-in printed circuit board assemblies (BG) with an electrical resistor (R) between the front panel (FP) and the sliding contact (K). Any electrostatic charge applied to the front panel (FP) is damped by the electrical resistor (R) before being dissipated to the mounting rack BGT. The novel mounting rack (BGT) has the advantage that an assembly (BG) can be inserted and withdrawn even while the other assemblies in the mounting rack (BGT) are in operation, without any interference signals that could adversely affect operation of the other assemblies in the mounting rack (BGT) being emitted.

Mounting rack for plug-in electrical printed circuit board assemblies

The front system has an upper and a lower end piece (5) which are fastened to the upper and lower front corner region (3), respectively, of the printed circuit board assembly (3). An upper and/or a lower lever pull handle (19), which is fitted to the upper and/or lower end piece respectively, is used for levering the printed circuit board assembly into and out of the mounting rack. A latching mechanism (25) is provided to fix the lever pull handle in the appropriate position when the printed circuit board assembly has reached the point where it has been fully inserted into the mounting rack. A push-button element (31) is integrated in the upper and/or lower end piece. When the lever pull handle is in its fixed position, the push-button element may be depressed to thereby act upon the appropriate lever pull handle, thereby actuating an external, electrical switching element. The electrical switching element, in turn, electrically enables and disables the printed circuit board assembly. The invention has the advantage of allowing the push-button element, as a result of its integration in a lower or an upper end piece, to be brought into an exactly definable position, so that even external switching elements with different external designs may be permanently and reliably actuated via the lever pull handle.
