Abstract:
An electrical contact for making a soldered connection between an insulated wire conductor (30) and a circuit board (40). The contact includes a tubular contact body (10) having a hollow interior (18). One end (24) of the contact body (10) has an insulation piercing edge (26) which promotes penetration of the contact body (10) through insulation (34) of the wire conductor (30) and into its conductive core (32) when the wire conductor (30) is pressed against the edge (26) of the contact body (10). The other end (22) of the contact body (10) is solderable to the circuit board (40). The hollow interior permits solder (50) to be drawn by capillary action through the contact body (10) and into the conductive core (32) of the wire (26). The hollow interior (18) may be coated with solder for use in establishing the soldered connection.
Abstract:
Procédé permettant de fixer des cosses de branchement à des conducteurs électriques pris dans des couches thermoisolantes ou des éléments analogues. Une plaque de contact est rivetée en place à l'endroit d'un trou traversant les couches plastiques (1, 2) et l'élément métallique (3). Selon ce procédé, la plaque (9) est rivetée en place près d'un trou (4) traversant les couches de plastique et la couche métallique (3) prise entre les deux premières à l'aide d'un rivet (6) creux. Du côté opposé, le rivet est recourbé autour d'un relèvement (8) formé à l'extrémité inférieure du trou (4), lequel a été formé au moyen d'une broche (5) de forme tronconique élevée à une température suffisamment haute, de telle sorte que le bord supérieur du trou se trouve embouti en creux pour former une surface de joint accueillant le rivet (6), la partie centrale formant un corps cylindrique creux exposant la surface métallique (7) au contact du rivet (6), tandis que la partie inférieure forme un relèvement (8) réalisant un scellement, de préférence renforcé sur son pourtour, ce qui augmente ainsi la pression de contact et assure l'étanchéité de la surface entourant la surface de contact.
Abstract:
An electrical connector (16) has first terminals (50) which are surface mounted to respective sides of a substrate (12) and second terminals (70) which extend through an edge surface of the substrate (12) to make electrical connection to an opening provided in the substrate. As the connector (16) is mated to the edge of the substrate (12), the connector (16) occupies a minimal space on the substrate (12).
Abstract:
The object of the description is a flexible throughput of a two-sided printed board (1), by which ruptures and electric breaks caused by the different thermal expansion properties of the materials in known throughputs are avoided, and which nevertheless allows the use of an inexpensive printed board material and of the wave soldering method. According to the invention, two holes are made into the printed board, into one of which a metal sleeve (4) is inserted. The sleeve is surrounded by a conductor foil (2), i.e. soldering fringe on the upper surface of the printed board. The second hole (5) is without a sleeve and comprises a conductor foil, i.e. soldering fringe on the lower surface of the printed board. The overshoot wire (6) is composed on the printed board so that its one arm (6a) is placed into the sleeve (4) and its other arm (6b) extends through the hole (5) below the printed board. In wave soldering, the lower surface of the printed board (1) touches the molten solder, which rises from the sleeve (4) and fixes this by soldering to the overshoot wire (6) and the upper foil (2) and simultaneously the second arm (6b) of the wire (6) is soldered to the lower conductor foil (3).
Abstract:
A cathode ray tube has a thin flexible circuit (48) comprising one or more films of polyimide with a plurality of conductive tracks deposited directly thereon for establishing electrical connection between a multi-pin leadthrough (45) passing through the wall of the tube's envelope (31) and terminals of electrically operable components within the envelope, e.g. electron gun (35) and beam-deflection electrodes (36,39 and 40). A number of track-carrying films may be stacked together to form a laminate structure. Such a flexible circuit avoids outgassing problems and, being thin and flexible, occupies minimal space and is easily routed around internal components to ease assembly
