Abstract:
In a module, press-fit connection using a pin terminal including a connection part separated into two parts and a flat plane parallel to the lengthwise direction in the separation part and perpendicular to the separation direction of the pin terminal is performed. A through-hole of a board is structured so that an inner diameter of the through-hole at a middle part in the thickness direction of the board is smaller than that at obverse and reverse surfaces of the board and the length of the middle part of the through-hole connected to the pin terminal is shorter than the length of the flat plane of the pin terminal.
Abstract:
A press fit passive component, such as a resistor or capacitor, adapted to fit within, or partially within, a via of a printed circuit board. In one example, the press fit passive component has a cylindrically shaped body with solderable terminals at either end of the body, and a dielectric collar disposed at least partially about the cylindrically shaped body.
Abstract:
An electronic component assembly includes an electrical component assembled to a base and mounted to a support. The component electrical leads protrude through holes, along a channel, and make contact with connectors on the base. The base is formed of a polymeric material and contains protrusions for mechanically supporting the electrical component. When the base is mounted to the support, the connectors complete the electrical connection between the electrical component and the support.

Multi-part circuit board comprising at least two partial boards (1, 2, 3, 4) and flexible signal lines (7), wherein at least one clamping element (10), which can be inserted into at least one clamping opening (12) of another partial board (4), is integrally molded onto at least one partial board (1).
Abstract:
An array of thin metallic foil strips of predetermined thickness electrically connected to a printed circuit board, cables or attached to wires. An associated power source, on the printed circuit board, or attached to the circuit board, cables or wires, directs an electrical current through L-shaped contacts to one or more of the strips in the array of foil strips. The foil strips are in contact with horizontal legs of the L-shaped contacts. Depending upon the use of the circuit board, the foil strips can be used to start or to end an operation. The selection of the foil strip makes use of the electrical properties of the selected metal such as its resistivity as well as the thickness, length and width of the foil strips to provide a strip with characteristics required to achieve a preselected result. As an electric current is provided by a power source, it passes through one or more foil strips. The application of current through the metallic material can be used to achieve a number of results, such as to act as a heating element.
