Abstract:
A press-fit fixing terminal is mountable to a wiring board by being inserted into a through-hole of the wiring board, and includes a flat plate section and a resilient contacting section. The flat plate section is made of metal thin plate and double-backed such that an end of the flat plate section is placed on a root side and a bent point works as an insertion tip when the terminal is inserted into the through-hole. The resilient contacting sections sandwich the double-backed portion of the flat plate section such that they are placed symmetrically with respect to the double-backed portion and both of the ridges of the resilient contacting section face outward viewed from the double-backed portion, so that each one of the resilient contacting sections forms a V-shape including an obtuse angle.
Abstract:
A film integrated circuit includes at least one row of connection terminals to be connected in metallized holes of a given diameter formed in a printed circuit board. The connection terminals have a widened portion, one side with a pocket-like clamping contour to be connected to pads of a film IC, and another side to be connected to the printed circuit board and having a strip-like, comparatively narrower connection piece adjoining the widened portion. At least one of the connection pieces has a V-bend in a bending region forming a spring with one free arm and another arm being connected to the widened portion, for plug contacting in the holes formed in the printed circuit board. The V-bend has a bending radius being markedly smaller than the given diameter of a corresponding one of the holes formed in the printed circuit board. The bent connection pieces have a material thickness in the bending region being reduced by approximately 50%.
Abstract:
Apparatus for adjusting capacitance between an electronic component and external circuitry. The electronic component is unitarily provided with a plurality of conductive leads for connection to external circuitry with at least one of the leads being configured to provide integral means for adjustment of capacitance. The configured lead is bent for a turnabout of about 180 degree change of direction such that when the component is mounted on a printed circuit board the portion of the lead distal of the component extends above the board and is positionally adjustable providing adjustable capactive coupling to other circuit components.
Abstract:
The connection of an electrical component to a printed circuit board wherein a lead to the component includes an offset being in frictional engagement with the walls of an opening within the circuit board, the apex of the offset being soldered to be able to electrically connect the lead to the printed circuit path on the underside of the board, the free end of the lead extending exteriorly of the board on the upper surface thereof.
Abstract:
A staking electrical contact for staking an electrical conductor onto a printed circuit board and in electrical engagement with a printed circuit path on the printed circuit board which comprises a body portion having spaced legs between which the electrical conductor is disposed and the legs are driven into slot means of the printed circuit board until the contact is bottomed whereupon the free ends of the legs are bent into engagement with the printed circuit path and soldered thereto.
Abstract:
An electronic device comprising a package comprising an encapsulated electronic chip, at least one at least partially exposed electrically conductive carrier lead for mounting the package on and electrically connecting the electronic chip to a carrier, and at least one at least partially exposed electrically conductive connection lead, and an electronic member stacked with the package so as to be mounted on and electrically connected to the package by the at least one connection lead.
Abstract:
A package (120), wherein the package (120) has at least one electronic chip (124), an encapsulation body (138) that encapsulates the electronic chip(s) (124), and a plurality of terminal pins (122) to connect the electronic chip(s) (124), wherein each of the said terminal pins (122) has an encapsulated section (126), which is encapsulated at least partially by the encapsulation body (138) and has an exposed section (128) that protrudes from the encapsulation body (138), and wherein at least a portion of the exposed sections (128) laterally extends from the encapsulation body (138) up to a reversal point (130) and laterally extends back from the reversal point (130) to the encapsulation body (138), so that a free end (132) of the exposed sections (128) is laterally aligned with or to a corresponding side wall (134) of the encapsulation body (138) or is spaced from the corresponding side wall (134) of the encapsulation body (138) laterally outwardly.
