Un tel problème se pose par exemple lorsqu'on souhaite relier un jack audio-stéréo au circuit imprimé, d'un téléphone mobile. En effet, ce branchement nécessite d'une part, la fixation et le positionnement corrects de l'embase du jack sur le circuit imprimé, et d'autre part, la mise à la masse dudit circuit de ce jack.Such a problem arises for example when wish to connect an audio-stereo jack to the printed circuit, of a mobile phone. Indeed, this connection requires on the one hand, fixing and positioning correct from the jack base on the printed circuit, and secondly, the grounding of said circuit of this jack.

Dans les téléphones mobiles connus les fonctions précitées sont réalisées par des moyens indépendants qui occupent chacun un emplacement dans le téléphone mobile. Ceci a pour effet de limiter les possibilités de miniaturisation de ce dernier, d'augmenter le nombre de pièces à monter et par conséquent le prix.In known mobile phones the functions above are carried out by independent means which each occupy a space in the mobile phone. This has the effect of limiting the possibilities of miniaturization of the latter, to increase the number of parts to mount and therefore the price.

Le but de l'invention est de réaliser un dispositif qui permet d'assurer simultanément les deux fonctions précitées.The object of the invention is to provide a device that allows both aforementioned functions.

Pour atteindre ce but, le dispositif selon l'invention est caractérisé en ce qu'il consiste en un élément découpé dans une feuille métallique et plié en forme de U, ce U étant engagé dans une gorge s'étendant sur la face supérieure du corps isolant de l'embase du jack et sur chacun des deux côtés de ce corps, les deux ailes dudit U comportant chacune à son extrémité une patte pliée à angle droit vers l'extérieur et destinée à être fixée sur le circuit imprimé, la base du U dudit élément portant une lame en contact élastique avec une partie du contact du jack.To achieve this goal, the device according to the invention is characterized in that it consists of a element cut from a metal sheet and folded in U-shaped, this U being engaged in a groove extending on the upper face of the insulating body of the base of the jack and on each of the two sides of this body, both wings of said U each having at its end a tab folded at right angles outwards and intended for be fixed on the printed circuit, the base of the U of said element carrying a blade in elastic contact with a part of the jack contact.

L'élément découpé et plié en U assure ainsi simultanément les fonctions de positionnement et de fixation précises de l'embase du jack sur le circuit imprimé et la fonction de contact avec une partie de contact par exemple de masse de ce jack. Une réduction de l'encombrement est également obtenue grâce à l'engagement de l'élément plié en U dans la gorge du corps isolant du jack.The cut and folded U-shaped element thus ensures simultaneously the positioning and precise fixing of the jack base on the circuit printed and contact function with part of eg ground contact of this jack. A discount space is also obtained thanks to the engagement of the U-shaped element in the groove of the insulating body of the jack.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, prise à titre d'exemple non limitatif, en référence à la figure annexée qui représente une vue en perspective d'un dispositif conforme à l'invention.Other features and benefits of the invention will emerge from the description which goes follow, taken by way of nonlimiting example, in reference to the appended figure which represents a view in perspective of a device according to the invention.

La figure 1 représente un dispositif permettant de positionner et de fixer d'une part une embase pour un jack 1 audio-stéréo sur le circuit imprimé d'un téléphone mobile et d'autre part permettant un contact électrique avec une partie de contact 2 de ce jack.Figure 1 shows a device for to position and fix on the one hand a base for a audio stereo jack 1 on the printed circuit board mobile phone and secondly allowing contact electric with a contact part 2 of this jack.

Conformément à l'invention, ce dispositif consiste en un élément 3 découpé dans une feuille métallique est plié en forme de U. Ce U est engagé dans une gorge 4 s'étendant sur la face supérieure 5 du corps isolant de l'embase du jack 1 et sur chacun des deux côtés 6 de ce corps. Les deux ailes 7 dudit U comportent chacune à son extrémité une patte 8 pliée à angle droit vers l'extérieur et destinée à être fixée sur le circuit imprimé par soudage ou par des vis. La base 9 du U de l'élément 3 porte une lame 10 en contact élastique avec la partie de contact 2 du jack. According to the invention, this device consists of an element 3 cut from a sheet metal is bent into a U shape. This U is engaged in a groove 4 extending over the upper face 5 of the body insulator from the jack 1 base and on each of the two 6 sides of this body. The two wings 7 of said U comprise each at its end a leg 8 folded at right angles outwards and intended to be fixed on the circuit printed by welding or by screws. Base 9 of the U of element 3 carries a blade 10 in elastic contact with the contact part 2 of the jack.

La profondeur de la gorge 4 est égale à l'épaisseur de la feuille dans laquelle est découpé l'élément 3 plié en U. De ce fait, la surface extérieure de cet élément 3 affleure la surface extérieure du corps isolant de l'embase du jack 1.The depth of the groove 4 is equal to the thickness of the sheet from which is cut element 3 folded into a U. As a result, the outer surface of this element 3 is flush with the exterior surface of the body insulator from the jack 1 base.

Par ailleurs, chaque aile 7 de l'élément 3 plié en U comporte une ouverture 11 destinée à être encliquetée sur un bec d'encliquetage 12 en saillie dans la gorge 4, sur chaque côté du corps isolant du jack.Furthermore, each wing 7 of the element 3 folded U-shaped has an opening 11 intended to be snapped onto a snap-on spout 12 projecting into groove 4, on each side of the insulating body of the jack.

La figure 1 montre d'autre part que la lame 10 s'étend perpendiculairement à l'un 13 des bords de la base 9 de l'élément 3 plié en U.Figure 1 shows on the other hand that the blade 10 extends perpendicular to one of the 13 edges of the base 9 of element 3 folded into a U.

De plus, cette lame 10 est pliée vers le bas et forme un angle α avec le plan P de la base 9 de l'élément 3 plié en U.In addition, this blade 10 is folded down and forms an angle α with the plane P of the base 9 of element 3 folded into a U.

En outre, la lame 10 est engagée dans une gorge 14 ménagée sur la surface supérieure du corps isolant du jack 1.In addition, the blade 10 is engaged in a groove 14 formed on the upper surface of the insulating body of the jack 1.

Comme montré également par la figure 1, l'extrémité de la lame 10 comporte une zone recourbée 15 destinée à venir en contact élastique avec la partie de contact de masse 2 du jack.As also shown in Figure 1, the end of the blade 10 has a curved zone 15 intended to come into elastic contact with the part of ground contact 2 of the jack.

Les principaux avantages du dispositif que l'on vient de décrire sont les suivants :

  • l'élément 3 plié en U grâce à son engagement dans la gorge 4 et à ses pattes 8 permet un positionnement et une fixation précises de cet élément au circuit imprimé du téléphone mobile ;
  • la lame flexible 10 réalisée d'une seule pièce avec l'élément 3 permet d'établir un contact avec la partie de contact 2 du jack ;
  • grâce à l'engagement de l'élément 3, y compris de sa lame 10 dans des gorges, l'encombrement de l'ensemble peut être réduit à quelques mm (le jack lui-même ayant un diamètre de 2,5 mm).
The main advantages of the device just described are as follows:
  • the element 3 folded into a U thanks to its engagement in the groove 4 and to its legs 8 allows precise positioning and fixing of this element to the printed circuit of the mobile phone;
  • the flexible blade 10 made in one piece with the element 3 makes it possible to establish contact with the contact part 2 of the jack;
  • thanks to the engagement of the element 3, including its blade 10 in grooves, the size of the assembly can be reduced to a few mm (the jack itself having a diameter of 2.5 mm).

Bien entendu l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut lui apporter de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the example of realization which we have just described and we can make many changes to it without depart from the scope of the invention.
