BROCHE FIXEE PAR SOUDAGE A UNE PLAQUETTE A CIRCUIT IMPRIME

L'INVENTION CONCERNE UNE BROCHE DESTINEE A CONNECTER UN CONDUCTEUR ELECTRIQUE A UNE PLAQUETTE A CIRCUIT IMPRIME. LA BROCHE COMPORTE UNE PREMIERE PARTIE 24 ENFONCEE DANS UN TROU DE LA PLAQUETTE UN CONDUCTEUR ELECTRIQUE 2 EST CONNECTE PAR UN CONTACT GLISSANT 8. LA DIMENSION D2 DE LA SECTION TRANSVERSALE DE LA SECONDE PARTIE 26 EST PLUS GRANDE QUE LA DIMENSION D1 DE LA SECTION TRANSVERSALE DE LA PREMIERE PARTIE 24 ET LA BROCHE 21 COMPORTE UN EPAULEMENT 27 A ARETES VIVES ENTRE CES DEUX PARTIES. PENDANT LE SOUDAGE, L'EPAULEMENT 27 EMPECHE, AVEC SES ARETES, LE FLUX D'ATTEINDRE LA SECONDE PARTIE 26 DE LA BROCHE 21.DOMAINE D'APPLICATION : MONTAGE DE CIRCUITS INTEGRES ET AUTRES CONNEXIONS SUR PLAQUETTES A CIRCUITS IMPRIMES, ETC. The invention relates to a pin (21) for connecting an electrical conductor (2) to a PCB (4). The pin has a first part (24) thrust into a hole in the PCB and a second part (26), to which the electrical conductor (2) is connected by a sliding contact (8). The cross-sectional dimension (d2) of the second part (26) is greater than the cross-sectional dimension (d1) of the first part (24), and between these parts the pin (21) has a shoulder (27) with sharp edges. The hole in the circuit board is coated with a metal which is connected via tabs (22) to electrical conductors (3) of the PCB(4). The pin (21) is soldered in the hole with the aid of soldering metal (25) and flux. When the flux is heated it creeps along the surface of the pin. During soldering, the shoulder (27) with the edges prevents the flux reaching the second part (26) of the pin (21 ), the second part having contact surfaces (29) on the pin (21) against the sliding contact (8) and where the flux would be a contact resistance. The pin (21) has the advantage that its first part (24) is narrow and that the tabs (22) can have a small outside diameter. There is thus created room for a large number of conductors (3) between two adjacent pins (21).
