Patent number: 4582375Abstract: The invention relates to a module holder for holding electronic modules in which two lateral parts are screwed to four connecting pieces. A printed circuit board is provided for the backwall wiring and to facilitate assembly and disassembly, it is clamped to the rear connecting pieces of the module holder with at least one elastic force accumulator. A suitable elastic force accumulator can be, for example, the resilient leg of a U-shaped plastic part, with the other leg being fastened form-lockingly on the corresponding connecting piece. Preferably this plastic part extends as a holding bar over the full length of the connecting piece, so the necessary air and creepage distances are obtained in a simple manner.Type: GrantFiled: April 11, 1984Date of Patent: April 15, 1986Assignee: Siemens AktiengesellschaftInventor: Roman Keller

Patent number: 4348687Abstract: A stack or column of thyristors and cooling capsules has two end pieces and a clamping frame of plastic surrounding the stack and the end pieces. The frame consists of two end-to-end half-shells having recesses in the outer surfaces into which, after assembly, turns of glass fiber are wound to form bundles which are then cast over with plastic. A clamping element is screwed into each of the end pieces, at least one of which is a resilient power accumulator. Since the clamping device consists of insulating plastic and is curved in the regions of the stack ends, a space-saving design is obtained.Type: GrantFiled: February 26, 1980Date of Patent: September 7, 1982Assignee: Siemens AktiengesellschaftInventors: Roman Keller, Gunter Kliesch

Patent number: 4061413Abstract: A metallic gasket in strip form for realizing a high-frequency-tight connection of detachable metallic shielding elements and, likewise, other metallic structural elements is disclosed. The gasket is placed in the gap between the elements and brings about a good electrical contact between the elements for frequencies up into the GHz range. More particularly, in accord with the invention, the gasket is provided with a multiplicity of triangular resilient tabs which protrude on both sides of the plane of the gasket, are arranged in at least one row running approximately parallel to the long sides of the gasket, and are disposed in side by side relationship such that the projections of adjacent tabs on the plane of the gasket are rotated by 180.degree.. Through suitable choice of the material and design of the tabs, a reliable and low-resistance contact is also achieved with the gasket in situations where the shielding and structural elements being connected are provided with corrosion protective layers.Type: GrantFiled: October 2, 1975Date of Patent: December 6, 1977Assignee: Siemens AktiengesellschaftInventor: Roman Keller

Patent number: 4006949Abstract: A cabinet for mounting electronic equipment is disclosed. At least two joints corresponding to each one of the side walls of the cabinet are provided for respectively connecting the bottom end part and the top end part of the cabinet to the same. Each of the joints includes three threaded bores arranged to define the respective corners of a triangle. Three threaded members threadably engage corresponding ones of the bores to join the side wall and the corresponding one of the end parts together. The joint configured in this manner ensures that the cabinet can always be screwed together square and true to size with a minimum of effort.Type: GrantFiled: March 22, 1973Date of Patent: February 8, 1977Assignee: Siemens AktiengesellschaftInventor: Roman Keller
