Abstract:
The invention describes a plug contact (1) for electrically contacting a circuit board (2) by inserting the plug contact (1) into a via hole (3) in the circuit board (2), the plug contact having two flat contact arms (4, 5) that are resilient relative to each other, and a connecting region (6), from which the two contact arms (4, 5) extend in the plug-in direction (E) of the plug contact (1), the plug contact (1) being punched as a single piece from a flat metallic material. The plug contact (1) according to the invention permits a high normal contact force even when dimensions are compact, and thus ensures a good, lasting electrical contact even when the via holes (3) have a small diameter. The plug contact is characterized in that in the connection region (6), adjacent to the two contact arms (4, 5), a recess (7) is formed, the distance between the two contact arms (4, 5) increases from the recess (7) towards the free ends (4a, 5a) of the contact arms, the two contact arms (4, 5) being spread apart relative to each other and the two contact arms (4, 5) together having a width (B), which is the same as or only slightly smaller than the diameter (D) of the corresponding via hole (3) in the circuit board (2).

Abstract:
A method for reducing the fitting thrust of golden finger (101,103) and a PCB (100). The method and the PCB (100) solve the problem of excessive inserting force of the golden finger (101,103) of the prior art, through modifying the shape of the edge of the PCB (100), the edge of the PCB open reeds of a connector (201, 203) at different time. The PCB (100) has at least one concave edge section or at least one convex edge section or at least one tilt edge section, and the edge can further be beveled. The bonding pads of the golden finger can be assorted, pin ends of a part of golden fingers (101, 103) can be partially removed or these golden fingers can be completely removed, the pin ends of a part of golden fingers (101,103) can be preserved. Through the method, the purpose of reducing the fitting thrust upon inserting the PCB (100) into the connector can be achieved.
Abstract:
In this application, a description is given of a passive component comprising two electric connections with a plug-in portion for securing and electrically connecting the component to a printed circuit board, for example an electrolytic capacitor. In accordance with the invention, this component is so constructed that both plug-in portions are provided with two pins, with the plug-in portions being so positioned that the four pins do not extend in a flat plane. By virtue of the measure in accordance with the invention, resoldering of such components can be dispensed with. The use of pins whose length and width are different enables the manual installation of the components in accordance with the invention in the correct position to be simplified.
