Il est connu, d'après le document DE 196 54 384, de souder en surface en mode CMS (SMD) une pièce de connexion sur un circuit imprimé. La pièce de connexion présente un trou taraudé qui est formé dans une collerette engagée dans un trou du circuit imprimé et qui est destiné à recevoir une vis assurant la fixation du circuit imprimé à un boîtier. La pièce de connexion est munie de picots pénétrant dans des orifices correspondants du circuit imprimé, pour empêcher la pièce de se dessouder It is known, from document DE 196 54 384, to surface weld in CMS (SMD) mode a connection piece on a printed circuit. The connection piece has a threaded hole which is formed in a flange engaged in a hole in the printed circuit and which is intended to receive a screw ensuring the fixing of the printed circuit to a housing. The connection piece is provided with pins penetrating into corresponding holes of the printed circuit, to prevent the piece from unsoldering

L'invention a pour but de permettre une pose et une fixation simplifiée d'organes ou de pièces divers sur un circuit imprimé au moyen d'écrous adaptés au montage en cooked printed. It also has the disadvantage of requiring an indexed rotation of the nut to align the pins with the corresponding holes in the printed circuit. The object of the invention is to allow a simplified installation and fixing of various organs or parts on a printed circuit by means of nuts suitable for mounting in

The nut has for example a generally circular toothed shape, with a flange

La description va être faite ci-après d'un mode de réalisation non limitatif de The description will be made below of a non-limiting embodiment of
l'invention, en regard des dessins annexés. the invention, with reference to the accompanying drawings.
La figure 1 est une vue en coupe du dispositif de fixation conforme à l'invention. Figure 1 is a sectional view of the fixing device according to the invention.
La figure 2 est une vue en perspective de l'écrou du dispositif. Figure 2 is a perspective view of the device nut.
La figure 3 représente l'écrou en vue de dessus. Figure 3 shows the nut from above.
Le dispositif illustré sur la figure 1 montre un écrou 10 fixé sur un circuit imprimé 20 afin de fixer à celui-ci un organe ou un accessoire quelconque 21, par exemple un radiateur, un insert, une entretoise, une tôle, etc.., au moyen d'une vis 22 coopérant avec l'écrou. L'écrou est fixé par brasure à une première face 24 du circuit imprimé, cette face recevant des composants électroniques non indiqués fixés par la matière The device illustrated in FIG. 1 shows a nut 10 fixed to a printed circuit 20 in order to fix to the latter any organ or accessory 21, for example a radiator, an insert, a spacer, a sheet metal, etc., by means of a screw 22 cooperating with the nut. The nut is fixed by brazing to a first face 24 of the printed circuit, this face receiving non-indicated electronic components fixed by the material
de brasure, et l'organe 21 à assembler est disposé sur une deuxième face 28, op- of solder, and the member 21 to be assembled is arranged on a second face 28, op-
posée à la première face, du circuit imprimé. La vis est à cet effet engagée dans la collerette de l'écrou du côté de la deuxième face 28 avec sa tête située sur la face placed on the first side of the printed circuit. The screw is for this purpose engaged in the flange of the nut on the side of the second face 28 with its head located on the face
libre de l'organe 21.free from organ 21.
L'écrou 10 est de forme générale circulaire dentée ou étoilée, avec en son centre une collerette 12 destinée à pénétrer dans un trou lisse 23 du circuit imprimé, la collerette présentant un trou taraudé 13 qui coopère avec le filetage 22a de la vis The nut 10 is of generally circular toothed or star shape, with in its center a flange 12 intended to penetrate a smooth hole 23 of the printed circuit, the flange having a tapped hole 13 which cooperates with the thread 22a of the screw
22. L'écrou 10 possède d'autre part une assise 14 dont le pourtour est doté d'enco- 22. The nut 10 also has a seat 14 whose periphery is provided with
ches 11 réparties régulièrement afin de constituer autant de logements pour la bra- ches 11 distributed regularly in order to constitute as many dwellings for the bra-
sure. L'écrou métallique est fabriqué par tout procédé approprié apte à fournir une assise 14 d'épaisseur e et une collerette 12 dépassant de l'assise avec une hauteur h supérieure à l'épaisseur e. De la sorte, on conserve une faible épaisseur limitant l'encombrement de l'écrou et favorisant l'insertion de la brasure dans les encoches safe. The metal nut is manufactured by any suitable process capable of providing a seat 14 of thickness e and a flange 12 projecting from the seat with a height h greater than the thickness e. In this way, a small thickness is kept, limiting the size of the nut and promoting the insertion of the solder in the notches.
11, tout en donnant à la collerette une hauteur de taraudage suffisante pour rece- 11, while giving the flange a sufficient tapping height to receive

Lors de l'opération de soudure CMS de l'écrou, opérée sur la première face 24 du circuit imprimé, la matière de brasure mouille d'une part l'interface 25 entre la face de l'assise 14 située vers la collerette, et d'autre part afflue dans les encoches 11, During the CMS soldering operation of the nut, operated on the first face 24 of the printed circuit, the solder material firstly wets the interface 25 between the face of the seat 14 located towards the flange, and on the other hand, flows into the notches 11,
comme indiqué en 26 sur la figure 1. as shown at 26 in Figure 1.
On obtient ainsi une bonne immobilisation en rotation de l'écrou sans devoir recourir à des moyens d'indexation tels que des picots ou d'autres moyens analogues qui A good immobilization in rotation of the nut is thus obtained without having to resort to indexing means such as pins or other similar means which

Les vis 22 sont introduites dans des orifices de l'organe 21 et vissées dans les trous taraudés 13 des écrous jusqu'à application des têtes 22b des vis 22 placed on its face 24 which is the object of the SMD soldering of the electronic components and the nuts 10. The screws 22 are introduced into the orifices of the member 21 and screwed into the tapped holes 13 of the nuts until the heads 22b of the screws 22 are applied
