Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A head or bottom element of a component support, having guide rails which are arranged side-by-side and aligned in an insertion direction for receiving a printed circuit board of a plug-in module. The guide rails are constituted or formed by one-piece guide elements of the head or bottom element. The head or bottom element includes an electrically conductive material at least over portions of its area. If the head or bottom element has a surface coating of electrically non-conductive material, at least partially in the area of the guide rail, it is then possible to achieve a dependable insulation of the printed circuit board from the head or bottom element in a simple and cost-effective manner.

Abstract: 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.

Abstract: A module support having two parallel cross struts which are interconnected by guide rails which have a guide fixture wherein printed circuit boards can be displaced in a longitudinal direction of the guide rails. One or more air guides are arranged at the side of the guide rails and the air guide of a guide rail which is not occupied by a printed circuit board can be covered with a cover. The guide rail can be connected to the cover by detent connections in order to produce a preassembled unit. As a result, the assembly of this cover is simplified.

Abstract: A modular chassis for housing pluggable computer module includes pre-assembled and pre-wired bottom functional section having desired computer components mounted thereto, a pre-assembled and pre-wired inner functional section for receiving the pluggable modules, and a pre-assembled and pre-wired top functional section having desired computer components mounted thereto. The inner functional section is supported within and electrically interconnected to the bottom functional section and is removable from the bottom functional section. The top functional section cooperates with the bottom functional section to at least partially enclose the inner functional section and retain the inner functional section therein. The top functional section is electrically interconnected to the inner functional section. The top functional section is removable from the inner functional section and the bottom functional section.

Abstract: A plug-in module intended for insertion into component carrier for electronic devices. The module is composed of: a circuit board for supporting electronic and electrical components; a face plate having two longitudinal edges which are fastened at a right angle to the circuit board by means of a bracket; and an extractor including a gripping member which projects from the face plate and has two projecting parallel side walls having bearing holes therein for receiving coaxial hinge pins located in the plane of the face plate so that the extractor is pivotal on the coaxial hinge pins. The longitudinal edges of the face plate have two oppositely disposed recesses for engaging the side walls of the extractor so that the hinge pins are seated in the recesses. The side walls of the extractor may be an integral part of the extractor or separate pieces which are attached to the extractor.
