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 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 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 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 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 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: The invention relates to an actuator element (1) for levering in and out printed circuit modules. Said actuator element comprises an end piece (11) that is adapted to be linked with a printed circuit module (3) and an actuator lever (12). Said actuator lever (12) is rotatably mounted on the end piece (11) and comprises at least one handle part (122) and one locking slide (123) that can be slid between at least two switch positions (A, B). The locking slide, in a first switch position (A), retains the actuator lever (12) in a first position (C) that corresponds to a fastened state of the printed circuit module (3), and releases the actuator lever (12) in a second switch position (B).

Abstract: The module rack has on its front (38) at least one upper and one lower crossrail (3, 4) and at least one left and one right vertical corner profile strip (5, 6). According to the present invention, a vertical mounting groove (8, 9) is formed onto at least one vertical corner profile strip (5,6).

Abstract: 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.

Abstract: 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.

Abstract: A contact spring strip including a plurality of contact springs (F) held together in a chain-like manner. Each contact spring (F) includes a hat region (H). The hat region (H) when in the plugged-on state of the contact spring strip grips the head region (HK) of the retaining strip (HS). Each contact spring (F) also includes a spring leaf (FB) which, starting from the hat region (H) on the front (HA) of the retaining strip (HS) is spread away outwards at a bending edge (K). In addition, each contact spring (F) includes two latching claws (RK1 and RK2) which, starting from the hat region (H), are cut free at the front (HA) of the retaining strip (HS) at the bending edge (K) in a spread away outwards manner and situated on both sides next to the spring leaf (FB), and which respectively have a retaining lug (RF1 and RF2) which is spread away upwards in the direction of the head region (HK) and the front (HA) of the retaining strip (HS) and has a latching edge (RA1 and RA2).
