ORGANE DE CONTACT ELECTRIQUE
POUR LA LIAISON DE COSSES DE CONNEXION
A UN CIRCUIT IMPRIME
La présente invention concerne un organe de contact électrique pour la liaison de cosses de connexion électrique à un circuit imprimé.ELECTRIC CONTACT MEMBER
FOR THE CONNECTION OF CONNECTION TERMINALS
TO A PRINTED CIRCUIT
The present invention relates to an electrical contact member for connecting electrical connection lugs to a printed circuit.
Actuellement, cette liaison est réalisée par le dépôt d'une crème conductrice à l'emplacement où la cosse traverse le circuit, au contact d'une piste électriquement conductrice. La crème est ensuite chauffée par microflamme ou par air chaud, ce qui provoque sa fusion, puis son durcissement au refroidissement. Currently, this connection is achieved by depositing a conductive cream at the location where the terminal crosses the circuit, in contact with an electrically conductive track. The cream is then heated by microflamme or by hot air, which causes it to melt, then harden on cooling.
Cette succession d'étapes est délicate à réaliser convenablement, et son coût est donc élevé. This succession of steps is difficult to carry out properly, and its cost is therefore high.
La présente invention vise à pallier ces inconvénients. The present invention aims to overcome these drawbacks.
A cet effet, I'invention a pour objet un organe de contact électrique pour la liaison à un circuit imprimé d'une cosse de connexion, caractérisé par le fait qu'il comprend
un corps métallique composé d'un ensemble de faces latérales délimitant un espace sensiblement parallélépipédique, ledit corps étant agencé pour être logé dans un trou de forme correspondante percé dans le circuit,
et des prolongements en saillie desdites faces pour sertir ledit organe dans ledit orifice,
au moins une de deux desdites faces en vis-à-vis étant conformée de manière à se rapprocher de l'autre dans sa partie centrale de manière à pincer par déformation élastique ladite cosse engagée dans ledit espace.To this end, the invention relates to an electrical contact member for connection to a printed circuit of a connection terminal, characterized in that it comprises
a metallic body composed of a set of lateral faces delimiting a substantially parallelepipedal space, said body being arranged to be housed in a correspondingly shaped hole drilled in the circuit,
and protruding extensions of said faces to crimp said member into said orifice,
at least one of two of said opposite faces being shaped so as to approach the other in its central part so as to pinch by elastic deformation said terminal engaged in said space.
Dans un mode de réalisation particulier de l'invention, lesdites faces en vis-à-vis sont les grandes faces du parallélépipède. In a particular embodiment of the invention, said facing faces are the large faces of the parallelepiped.
Avantageusement, au moins un desdits prolongements est soudé sur une piste conductrice dudit circuit imprimé. Advantageously, at least one of said extensions is soldered onto a conductive track of said printed circuit.
Le principal avantage de l'invention réside dans le fait que l'organe de contact selon l'invention peut être aisément introduit dans le trou prévu à cet effet, puis serti et enfin soudé à la vague en même temps que les composants montés sur le circuit imprimé. Les opération de sertissage et de soudage sont réalisées en même temps pour tous les organes de contact du circuit. Ensuite, la cosse est engagée dans l'espace central et la liaison s'effectue simplement par contact élastique à sec. The main advantage of the invention lies in the fact that the contact member according to the invention can be easily introduced into the hole provided for this purpose, then crimped and finally welded to the wave at the same time as the components mounted on the printed circuit board. The crimping and welding operations are carried out at the same time for all the contact members of the circuit. Then, the terminal is engaged in the central space and the connection is made simply by elastic dry contact.
On décrira maintenant, à titre d'exemple non limitatif, un mode de réalisation particulier de l'invention, en référence aux dessins schématiques annexés dans lesquels:
- la figure 1 est une vue en perspective d'un organe de contact selon l'invention;
- la figure 2 est une vue en coupe transversale d'un tel organe monté sur un circuit imprimé avec une cosse en place;
- la figure 3 est une vue partielle en coupe longitudinale similaire à la figure 2; et
- la figure 4 est également une vue partielle en coupe longitudinale lors du montage de l'organe de contact sur le circuit imprimé.A particular embodiment of the invention will now be described, by way of nonlimiting example, with reference to the appended schematic drawings in which:
- Figure 1 is a perspective view of a contact member according to the invention;
- Figure 2 is a cross-sectional view of such a member mounted on a printed circuit with a terminal in place;
- Figure 3 is a partial view in longitudinal section similar to Figure 2; and
- Figure 4 is also a partial view in longitudinal section during assembly of the contact member on the printed circuit.
L'organe de contact 1 est réalisé d'une seule pièce en feuillard métallique, par exemple de l'ordre de 0,2 mm d'épaisseur. The contact member 1 is made in a single piece of metal strip, for example of the order of 0.2 mm thick.
II est formé pour l'essentiel d'un corps parallélépipédique 2 délimité par deux petites faces d'extrémité 3 et 3', et deux grandes faces longitudinales 4 et 4'. La hauteur h du corps 2 est légèrement inférieure à l'épaisseur e du circuit imprimé 5 auquel est destiné l'organe 1. It is essentially formed by a parallelepiped body 2 delimited by two small end faces 3 and 3 ', and two large longitudinal faces 4 and 4'. The height h of the body 2 is slightly less than the thickness e of the printed circuit 5 for which the member 1 is intended.
Les grandes faces 4 et 4' du corps 2 ne sont pas planes, mais se rapprochent progressivement l'une de l'autre vers le haut, dans leurs parties longitudinalement médianes, 6 et 6' respectivement. Chacune de ces faces forme ainsi une sorte de voûte dont la concavité est orienté vers l'extérieur du corps 2. The large faces 4 and 4 'of the body 2 are not planar, but progressively approach each other upwards, in their longitudinally median parts, 6 and 6' respectively. Each of these faces thus forms a sort of vault whose concavity is oriented towards the outside of the body 2.
Le long du bord inférieur de chaque grande face, une saillie longitudinale est découpée et rabattue sensiblement perpendiculairement à cette face vers l'extérieur du corpus, pour former un rabat 7 de butée. On verra ci-après l'utilité de ces rabats. Along the lower edge of each large face, a longitudinal projection is cut and folded down substantially perpendicular to this face towards the outside of the corpus, to form a flap 7 of abutment. We will see below the usefulness of these flaps.
De même, le long du bord supérieur de chaque petite face du corps 2, une patte de sertissage 8 permet le montage de l'organe 1 sur le circuit imprimé 5. A cet effet, I'organe 1 est introduit par en-dessous dans un trou 9 percé dans le circuit 5, jusqu'à ce que le rabat 7 vienne en butée contre la face inférieure 10 du circuit. Les extrémités des pattes 8, qui dépassent de la face supérieure il du circuit, sont alors repliées contre cette face de manière à sertir l'organe 1 dans le trou 9. On observera que, dans le cas présent, les pattes 8 sont repliées sur une piste conductrice 12 du circuit 5. Similarly, along the upper edge of each small face of the body 2, a crimping lug 8 allows the member 1 to be mounted on the printed circuit 5. For this purpose, the member 1 is introduced from below into a hole 9 drilled in the circuit 5, until the flap 7 abuts against the underside 10 of the circuit. The ends of the legs 8, which protrude from the upper face il of the circuit, are then folded against this face so as to crimp the member 1 into the hole 9. It will be observed that, in the present case, the legs 8 are folded over a conductive track 12 of circuit 5.
Ce montage des organes 1 sur le circuit 5 s'effectue dans le cadre de la mise en place des composants électroniques sur ce circuit. Un cache 13 est alors introduit dans l'espace central de l'organe 1 de manière que sa surface d'extrémité 14 affleure la surface 11 du circuit. This mounting of the members 1 on the circuit 5 is carried out in the context of the installation of the electronic components on this circuit. A cover 13 is then introduced into the central space of the member 1 so that its end surface 14 is flush with the surface 11 of the circuit.
Le circuit imprimé 5 ainsi équipé est passé à la machine de soudage à la vague pour souder les composants et les organes 1. Le cache empêche la remontée du métal en fusion dans le trou 9. On voit sur les figures une soudure 15 entre une patte 8 et une piste conductrice 12, après retrait du cache 13. The printed circuit 5 thus equipped is passed to the wave welding machine to weld the components and the members 1. The cover prevents the ascent of the molten metal in the hole 9. We see in the figures a weld 15 between a tab 8 and a conductive track 12, after removal of the cover 13.
Les figures 2 et 3 montrent une cosse 16 engagée dans un organe de liaison selon l'invention. La cosse écarte élastiquement les parties en voûte 6 et 6' des faces 4 et 4'. Du fait que les parties d'extrémité de ces faces sont bloquées longitudinalement et en appui contre les flancs du trou 9, il se produit un arc-boutement des parties en voûte 6 et 6', qui assure un contact ferme entre la cosse et l'organe de liaison. Figures 2 and 3 show a terminal 16 engaged in a connecting member according to the invention. The terminal elastically spreads the arch parts 6 and 6 'from the faces 4 and 4'. Due to the fact that the end parts of these faces are blocked longitudinally and in abutment against the sides of the hole 9, an arching of the arch parts 6 and 6 ′ occurs, which ensures firm contact between the terminal and the 'liaison body.
