- the body is made in two complementary parts each comprising a half-housing for the end of the coaxial cable, the two parts being able to close on said end of the coaxial cable to submit to it.
- each pawn of contact comprises, opposite its external end projecting from the connection face, one end internal to the body opening into the housing, each internal end being arranged so that the core, respectively the outer braid, of the coaxial cable enters contact with the pin when the coaxial cable is put in place with its bare end in the housing of the body.
- the contact pins are produced by compaction of very small diameter metal wires, for example 0.01 mm diameter molybdenum wires.
- the means fixing consists of a base adapted to receive the body and to hold it by snap-fastening with its connection face against the printed circuit board.
- This base is advantageously provided with studs capable of penetrate forcefully into holes made for this purpose in the printed circuit board.
- the device shown in the drawing comprises a body 1 of general parallelepiped shape and a base 2 constituting, at sense of the invention, a means of fixing the body to a card printed circuit 3.
- the body 1 is mounted at the end of a coaxial cable 4 which includes, inside its insulating sheath 5, a metal braid 6 of shielding and a central conductive core 7.
- the body 1 is divided into two parts, namely, an upper part 1 a and a lower part 1 b which can be joined to one another by means of studs 8 which project from the face of the lower part 1 b located opposite the upper part 1 a and with corresponding through orifices 9 provided in the upper part 1 a .
- a housing is provided, for the coaxial cable 4, inside body 1.
- This housing is produced in two half-housings which are each provided in one of the two parts 1 a , and 1 b of the body, so that the axis of the housing is located in the connection plane of the two parts 1 a , 1 b of the body.
- the half-housing comprises three sections semicylindrical diameter decreasing, namely, a portion 10 of diameter substantially equal to that of the cladding 5, a length 11 of diameter substantially equal to that of the braid outer 6 and a section 12 of diameter substantially equal to that of the central core 7.
- the large diameter section 10 opens onto one of the lateral faces 13 of the body 1, a tooth 14 formed by a portion of a collar of smaller diameter extending over approximately 90 ° being provided at the mouth of said section 10 to tighten the sheath 5 when the two parts 1 a and 1 b of the body are assembled in order to maintain the coaxial cable 4 in its housing.
- the half-housing of the lower part 1 b comprises sections 10 and 11 identical to those of the upper part 1 a .
- the lower part 1b comprises a parallelepipedic cavity 12 '.
- the lower part 1b further comprises two through passages 15 and 16 which extend, for the passage 15, between the section 11 and the lower face 17 of the part 1b , which lower face 17 constitutes, within the meaning of the invention, the connection face of the body 1 and, for the passage 16, between the parallelepiped cavity 12 'and said connection face 17.

- cutouts 24, 25 and this window 26 thus define a sort of handle 27, in the shape of an inverted U, which is joined to the frame of bottom 20 by the ends of its branches and which presents, given the thinness of its branches, an elasticity sufficient to allow lateral movement of its part upper 27.
- the walls 21 and 23 are identical and are each symmetrical about a vertical axis (relative to the drawing) passing through their middle.

- the height of the ears 28 on the body 1 is determined by so that their upper edges 28a lie in the vicinity immediately of the horizontal branch of the handles 27 when the body is placed in the base. Said body is thus snapped into said base.
- the base includes a pad 29 at the four corners of its face lower while the body comprises two studs 30 projecting from its connection face 17, aligned with the passages 15 and 16 and of on either side of these.
- the pads 30 have the function of protecting the ends of the contact pins 18 and 19 when the body is not in place in the base.
- a conductive track 34 enters the metallization 33 up to an imprint 35 which is located opposite the contact pin 19.
- Coaxial cable 4 is therefore connected to the circuit board printed 3 without any soldering and with a number of pieces reduced, each of these parts also being economical to achieve.

Description
La présente invention concerne un dispositif pour raccorder un câble coaxial à une carte de circuit imprimé.The present invention relates to a device for connecting a coaxial cable to a printed circuit board.
On connaít déjà des dispositifs permettant de raccorder un câble coaxial à une carte de circuit imprimé qui sont constitués par deux éléments de connecteurs, l'un mâle, l'autre femelle, l'un étant monté à l'extrémité du câble coaxial, l'autre étant assujetti à la carte de circuit imprimé, par soudure ou par insertion à force dans des trous prévus à cet effet dans la carte.There are already known devices for connecting a coaxial cable to a printed circuit board which consist of two connector elements, one male, the other female, one being mounted at the end of the coaxial cable, the other being subject to the printed circuit board, by soldering or by forced insertion into holes provided for this purpose in the card.
Le raccordement électrique entre le câble coaxial et la carte est alors obtenu en accouplant les deux éléments de connecteurs.The electrical connection between the coaxial cable and the card is then obtained by coupling the two connector elements.
Ces dispositifs connus présentent l'inconvénient d'être relativement chers à réaliser car ils exigent la fabrication et l'assemblage de nombreuses pièces de grande précision.These known devices have the disadvantage of being relatively expensive to make because they require manufacturing and the assembly of many high precision parts.
En outre, l'installation de tels dispositifs, d'une part à l'extrémité du câble coaxial, d'autre part sur la carte de circuit imprimé, implique un nombre important de manipulations. In addition, the installation of such devices, on the one hand to the end of the coaxial cable, on the other hand on the circuit board printed, involves a significant number of manipulations.
On connaít par WO-A-9 517 024, dont les caractéristiques font l'objet du préambule
de la revendication 1, un dispositif pour raccorder un câble coaxial à une carte de circuit
imprimé comportant un corps tronconique apte à être fixé par sertissage à l'extrémité d'un
câble coaxial et comprenant des moyens de contact à l'âme centrale du câble coaxial et
respectivement à la tresse externe de celui-ci, lesdits moyens de contact, constitués par des
enroulements hélicoïdaux comportant des prolongements aptes à être fixés sur une carte de
circuit imprimé.We know from WO-A-9 517 024, the characteristics of which are the subject of the preamble
of

MOTOROLA TECHNICAL DEVELOPMENTS
La présente invention vise à proposer un dispositif pour raccorder un câble coaxial à une carte de circuit imprimé, sans opérations de soudure, en utilisant un nombre réduit de pièces faciles à fabriquer et à assembler pour assurer le raccordement du câble à la carte.The present invention aims to provide a device for connecting a coaxial cable to a printed circuit board, without soldering operations, using a reduced number of easy to manufacture and assemble parts to ensure cable connection to the board.
Les caractéristiques de l'invention font l'objet de la revendication 1. The features of the invention are the subject of
On comprend que les deux pions de contact viennent s'appuyer contre la carte de circuit imprimé lorsque la face de raccordement du corps y est appliquée, grâce aux moyens de fixation.We understand that the two contact pins come to rest against the printed circuit board when the connection face of the body is applied to it, thanks to the fixing means.
Il suffit donc de prévoir, sur cette carte de circuit imprimé, des pistes situées en regard des pions de contact, pistes contre lesquelles les extrémités externes desdits pions de contact viennent prendre appui lorsque le corps est appliqué contre la carte de circuit imprimé.It is therefore sufficient to provide, on this printed circuit board, tracks opposite the contact pins, tracks against which the outer ends of said contact pins come take support when the body is pressed against the card printed circuit board.
De cette manière, on réalise sans soudure un raccordement électrique entre les pistes de la carte de circuit imprimé et le câble coaxial.In this way, a seamless connection is made between the tracks on the printed circuit board and the coaxial cable.
Dans un mode de réalisation préféré de l'invention, le corps est réalisé en deux parties complémentaires comprenant chacune un demi-logement pour l'extrémité du câble coaxial, les deux parties étant aptes à se refermer sur ladite extrémité du câble coaxial pour s'y assujettir.In a preferred embodiment of the invention, the body is made in two complementary parts each comprising a half-housing for the end of the coaxial cable, the two parts being able to close on said end of the coaxial cable to submit to it.
Dans un mode de réalisation particulier, chaque pion de contact comporte, à l'opposé de son extrémité externe dépassant de la face de raccordement, une extrémité interne au corps débouchant dans le logement, chaque extrémité interne étant agencée de manière que l'âme, respectivement la tresse externe, du câble coaxial entre en contact avec le pion lorsque le câble coaxial est mis en place avec son extrémité dénudée dans le logement du corps.In a particular embodiment, each pawn of contact comprises, opposite its external end projecting from the connection face, one end internal to the body opening into the housing, each internal end being arranged so that the core, respectively the outer braid, of the coaxial cable enters contact with the pin when the coaxial cable is put in place with its bare end in the housing of the body.
Avantageusement, les pions de contact sont réalisés par compactage de fils métalliques de très faible diamètre, par exemple des fils de molybdène de 0,01 mm de diamètre.Advantageously, the contact pins are produced by compaction of very small diameter metal wires, for example 0.01 mm diameter molybdenum wires.
Dans un mode de réalisation préféré de l'invention, le moyen de fixation est constitué par une embase apte à recevoir le corps et à le maintenir par encliquetage avec sa face de raccordement contre la carte de circuit imprimé.In a preferred embodiment of the invention, the means fixing consists of a base adapted to receive the body and to hold it by snap-fastening with its connection face against the printed circuit board.
Cette embase est avantageusement munie de plots aptes à pénétrer en force dans des perçages réalisés à cet effet dans la carte de circuit imprimé.This base is advantageously provided with studs capable of penetrate forcefully into holes made for this purpose in the printed circuit board.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant un mode de réalisation donné à titre d'exemple non limitatif, en référence au dessin annexé dans lequel :
- la figure 1 est une vue en perspective d'un dispositif selon un mode de réalisation de l'invention,

Le dispositif représenté sur le dessin comprend un corps 1 de
forme générale parallélépipédique et une embase 2 constituant, au
sens de l'invention, un moyen de fixation du corps sur une carte de
circuit imprimé 3.The device shown in the drawing comprises a
Le corps 1 est monté à l'extrémité d'un câble coaxial 4 qui
comprend, à l'intérieur de sa gaine isolante 5, une tresse métallique

solidariser l'une à l'autre grâce à des plots 8 qui font saillie de
la face de la partie inférieure 1b située en regard de la partie
supérieure 1a et à des orifices traversant correspondants 9 prévus
dans la partie supérieure 1a.The
Un logement est prévu, pour le câble coaxial 4, à l'intérieur
du corps 1.A housing is provided, for the
Ce logement est réalisé en deux demi-logements qui sont chacun
prévu dans l'une des deux parties 1a, et 1b du corps, de sorte
que l'axe du logement se situe dans le plan de raccordement des deux
parties 1a, 1b du corps.This housing is produced in two half-housings which are each provided in one of the two
Dans la partie supérieure 1a, le demi-logement comprend
trois tronçons demi-cylindriques de diamètre décroissant, à savoir,
un tronçon 10 de diamètre sensiblement égal à celui de la gaine 5, un
tronçon 11 de diamètre sensiblement égal à celui de la tresse externe
6 et un tronçon 12 de diamètre sensiblement égal à celui de l'âme
centrale 7.In the
Le tronçon de grand diamètre 10 débouche sur l'une des faces
latérales 13 du corps 1, une dent 14 formée par une portion de
collerette de plus petit diamètre s'étendant sur environ 90° étant
prévue à l'embouchure dudit tronçon 10 pour serrer la gaine 5 lorsque
les deux parties 1a et 1b du corps sont assemblées afin de
maintenir le câble coaxial 4 dans son logement.The
Le demi-logement de la partie inférieure 1b comprend des
tronçons 10 et 11 identiques à ceux de la partie supérieure 1a.The half-housing of the
En revanche, en regard du tronçon 12, la partie inférieure
1b comprend une cavité parallélépipédique 12'.On the other hand, opposite the
La partie inférieure 1b comprend en outre deux passages
traversants 15 et 16 qui s'étendent, pour le passage 15, entre le
tronçon 11 et la face inférieure 17 de la partie 1b, laquelle face
inférieure 17 constitue, au sens de l'invention, la face de
raccordement du corps 1 et, pour le passage 16, entre la cavité
parallélépipédique 12' et ladite face de raccordement 17.The
Des pions de contact 18, 19, réalisés par compactage de fils
de molybdène et présentant par conséquent une certaine élasticité
axiale, sont logés dans les passages 15 et 16 avec leurs extrémités
dépassant de part et d'autre desdits passages.Contact
Comme on le voit à la figure 4, lorsque les parties 1a et
1b du corps 1 sont réunies, les extrémités supérieures des pions de
contact 18 et 19, ou extrémités internes au corps au sens de
l'invention, sont comprimées et entrent en contact avec, d'une part,
la tresse externe 6, d'autre part, l'âme centrale 7 du câble coaxial.As seen in Figure 4, when the
L'embase 2, qui est réalisée en matière plastique, présente
une forme extérieure parallélépipédique ouverte sur sa face
correspondant à la face 13 du corps 1, ainsi que sur ses faces
supérieure et inférieure, parallèles à la carte de circuit imprimé 3.The
Elle comporte ainsi un cadre de fond 20 et trois parois
latérales 21, 22 et 23.It thus comprises a
La face latérale 22, qui est opposée à la face ouverte de
l'embase 2, est pleine, tandis que les faces latérales 21 et 23
comprennent, d'une part, deux découpes 24 et 25 qui s'étendent depuis
le bord supérieur de la paroi jusqu'au voisinage du cadre de fond 20
et une fenêtre 26 réalisée entre les découpes 24 et 25 et s'étendant
depuis le voisinage du bord supérieur de la paroi jusqu'au voisinage
du cadre de fond 20.The
Ces découpes 24, 25 et cette fenêtre 26 délimitent ainsi une
sorte d'anse 27, en forme de U inversé, qui est réunie au cadre de
fond 20 par les extrémités de ses branches et qui présente,
compte-tenu de la faible épaisseur de ses branches, une élasticité
suffisante pour permettre un débattement latéral de sa partie
supérieure 27.These
Comme on le voit sur le dessin, les parois 21 et 23 sont
identiques et sont chacune symétrique par rapport à un axe vertical
(par rapport au dessin) passant par leur milieu.As can be seen in the drawing, the
La partie supérieure 1a du corps 1 comporte, comme on le
voit sur la figure 3, des oreilles latérales 28 qui s'étendent
parallèlement à l'axe du câble coaxial 4 sur une longueur
correspondant à celle de la fenêtre 26 de l'embase 2.The
La section sensiblement triangulaire des oreilles 28 permet
leur encliquetage dans les anses 27 par déformation latérale de ces
dernières lorsque l'on enfonce le corps 1 dans l'embase 2, selon un
mouvement de translation perpendiculaire à la carte de circuit
imprimé 3, en direction de celle-ci.The substantially triangular section of the
La hauteur des oreilles 28 sur le corps 1 est déterminée de
manière que leurs bords supérieurs 28a se situent au voisinage
immédiat de la branche horizontale des anses 27 lorsque le corps est
mis en place dans l'embase. Ledit corps est ainsi encliqueté dans
ladite embase.The height of the
L'embase comprend un plot 29 aux quatre coins de sa face
inférieure tandis que le corps comprend deux plots 30 en saillie de
sa face de raccordement 17, alignés avec les passages 15 et 16 et de
part et d'autre de ces derniers.The base includes a
Les plots 30 ont pour fonction de protéger les extrémités des
pions de contact 18 et 19 lorsque le corps n'est pas mis en place
dans l'embase.The
Pour recevoir l'embase et le corps, on a réalisé dans la carte
de circuit imprimé 3, quatre passages traversants 31 en regard des
plots 29 et deux orifices 32 en regard des plots 30.To receive the base and the body, we made in the card

formant une plaque de masse.Almost the entire surface of the printed

Lorsque l'embase est mise en place sur la carte de circuit
imprimé 3 et que le corps 1 est encliqueté dans l'embase, comme on le
voit à la figure 5, le pion de contact 19 entre en contact avec la
piste conductrice 34, reliant ainsi électriquement l'âme centrale 7
du câble coaxial 4 et ladite piste conductrice 34, tandis que la
tresse externe 6 est reliée à la masse par le pion de contact 18 qui
prend appui sur la plaque de masse 33 au niveau de l'empreinte 36.When the base is placed on the circuit board

imprimé 3 sans aucune soudure et moyennant un nombre de pièces
réduit, chacune de ces pièces étant par ailleurs économique à
réaliser.
