Abstract:
The invention relates to an electrical contact arrangement of a spring contact element (10) on a printed circuit board (12) with a soldering area (16) arranged on a surface of the printed circuit board (12) and a planar contact area (18) arranged on the soldering area (16), wherein the spring contact element (10) can be arranged on the contact area (18).
Abstract:
The invention relates to a force-absorbing connection, comprising a force-absorbing element (16) having an internal thread (18) and a force-application element (24) having a bore for a screw (26), wherein the force-absorbing element (16) comprises a hollow cylindrical section (20) between the internal thread (18) and a base plate (14) facing the force-application element (24), the hollow cylindrical section having an inside diameter that is significantly greater than the outside diameter of the screw (26). The force-application element (24) has a hollow cylindrical boss (30) around the bore, the hollow cylindrical boss extending to the force-absorbing element (16) and having an outside diameter that corresponds approximately to the inside diameter of the hollow cylindrical section (20) of the force-absorbing element (16) and being provided with inner grooves (32), slits, or holes that extend parallel to the axial direction of the boss.
Abstract:
A circuit board device (10), in particular for an electric power consuming device in a motor vehicle, comprising a circuit board (11) with a substrate (18) and at least one layer (17) of electrically conductive pattern, and at least one electronic component (12-16) mounted on said circuit board (11) and electrically connected via said electrically conductive pattern (17), characterised in that said circuit board device (10) comprises at least one electrically conducting bridging bar (27, 28) connected to the surface of said circuit board (11) with end sections (31, 32, 35, 36), and spaced from the surface of said circuit board (11) in a middle section (39, 40).
Abstract:
The invention relates to a printed circuit or substrate plate (10) which is intended to receive electronic components and is provided with printed conductor tracks (12). According to the invention, one or more conductor bars (18) are mounted one after the other between the connecting conductor surfaces (140, 142, 144), said conductor bars (18) being electrically interconnected during a subsequent wave soldering process or in a remelt furnace.
Abstract:
The invention relates to a wire-printed circuit board or card (1) comprising conductors (6) that run on and/or in the circuit board or card between connection points (4). The aim of the invention is to improve a circuit board of this type. To achieve this, at least one of the conductors (6) has a rectangular or square cross-section. In addition, at least some of the conductors have a hollow cross-section, in which a coolant or heating agent circulates.
Abstract:
A wiring board formed with electric circuits is provided, wherein said electric circuits are formed by comprising straight bus bar segments (11-13), each of the straight bus bar segments having contact portions (11a-13a) at opposite ends thereof, said wiring board having means for bringing the respective contact portions into electrical contact.
