Description

La présente invention concerne un connecteur électrique pour carte à circuit imprimé, en particulier pour une utilisation dans le domaine automobile.The present invention relates to an electrical connector for a printed circuit board, in particular for use in the automotive field.

Dans la fabrication des modules électriques et/ou électroniques du type comportant des composants électriques et/ou électroniques montés sur une carte à circuit imprimé, on utilise de plus en plus des composants à montage en surface, couramment appelés composants CMS (Composants à Montage en Surface). A cet effet, les composants CMS, munis de pattes de connexion appropriées, sont posés sur des plages conductrices sur la surface d'une carte à circuit imprimé, qui ont été préalablement revêtues d'une pâte à braser par une technique de sérigraphie, puis on fait passer la carte à circuit imprimé portant les composants CMS dans un four à refusion afin de souder les pattes de connexion des composants CMS à leur plages conductrices respectives sur la carte à circuit imprimé.In the manufacture of electrical components and / or electronic type having electrical and / or electronic mounted on a printed circuit board, is used more and more surface mount components, commonly called SMD components (C OMPONENTS M ounting S urface). For this purpose, the SMD components, provided with suitable connecting tabs, are placed on conductive pads on the surface of a printed circuit board, which have been previously coated with a solder paste by a screen printing technique, and then The printed circuit board carrying the SMD components is passed through a reflow oven to solder the connection pads of the SMD components to their respective conductive pads on the printed circuit board.

L'utilisation de cette technique suppose que le composant a été développé exprès pour ce type de technique de soudage pour la connexion, en particulier qu'il dispose de pattes de connexion appropriées.The use of this technique assumes that the component has been developed specifically for this type of welding technique for the connection, in particular that it has suitable connection tabs.

Or, il existe de multiples composants électriques qui ont été développés pour être fixés par d'autres techniques sur une carte à circuit imprimé, en particulier des circuits imprimés à double face.However, there are multiple electrical components that have been developed to be fixed by other techniques on a printed circuit board, in particular double-sided printed circuits.

Un problème particulier se pose pour les connecteurs, notamment ceux dont les fiches de connexion sont reliées au circuit imprimé par exemple de la face supérieure de la carte et qui doivent traverser la carte pour constituer des broches d'un connecteur sur l'autre face de la carte à circuit imprimé.A particular problem arises for the connectors, especially those whose connection plugs are connected to the printed circuit for example of the upper face of the card and which must cross the card to form pins of a connector on the other side of the card. the printed circuit board.

Traditionnellement, de tels connecteurs sont fixés via un procédé de soudage des fiches nécessitant non seulement le pré-positionnement du connecteur sur la carte à circuit imprimé de façon que les broches traversent la carte, mais également le retournement de la carte pour effectuer le soudage des fiches et puis un dernier retournement de la carte à circuit imprimé.Traditionally, such connectors are fixed via a plug welding process requiring not only the pre-positioning of the connector on the printed circuit board so that the pins pass through the card, but also the reversal of the card to perform the welding of the connectors. plugs and then a final flip of the circuit board.

Pour éviter le double retournement de la carte à circuit imprimé lors du soudage du connecteur, on souhaiterait pouvoir appliquer la technique de soudage par refusion également à un connecteur traversant la carte à circuit imprimé.To avoid double reversal of the printed circuit board during soldering of the connector, it would be desirable to apply the reflow soldering technique also to a connector passing through the printed circuit board.

Cependant, la simple application de la technique de soudage par refusion aux connecteurs existants ne permet pas d'assurer de bonnes connexion électrique et fixation mécanique de ces fiches pour les plages de courant requises.However, the simple application of the reflow soldering technique to the existing connectors does not ensure good electrical connection and mechanical fixing of these plugs for the required current ranges.

On connaît des connecteurs électriques montés par un procédé de refusion par exemple dans le document US 4,641,426 .Electrical connectors are known that are mounted by a reflow method, for example in the document US 4,641,426 .

Toutefois, il s'agit ici d'un connecteur non traversant qui n'est pas adapté à toutes les utilisations nécessaires, en particulier lorsque la partie femelle du connecteur doit être branchée sur la face de la carte à circuit imprimé, opposée à la face de la carte présentant les circuits et accueillant les composants CMS, car cela nécessite que les broches de connexion traversent la carte à circuit imprimé.However, this is a non-through connector that is not suitable for all necessary uses, especially when the female part of the connector must be connected to the face of the printed circuit board, opposite to the face of the board presenting the circuits and hosting the CMS components, as this requires that the connection pins pass through the printed circuit board.

On connaît également du document DE 102 49 575 une carte à circuits imprimés qui est munie de composants SMD (« surface mounted devices » - c'est-à-dire de composants montés sur la surface de la carte à circuit imprimé).Document is also known DE 102 49 575 a printed circuit board which is provided with surface mounted devices (SMDs) - that is, components mounted on the surface of the printed circuit board.

Ce document décrit un connecteur électrique mâle pour carte à circuits imprimés comprenant plusieurs broches de connexion électrique destinées à traverser à l'état monté la carte à circuits imprimés. Une première extrémité de branchement d'une broche est apte à entrer dans un connecteur électrique femelle associé et sa seconde extrémité de connexion est destinée à être reliée électriquement sur des plages prédéfinies de la face de la carte à circuit imprimé opposée à celle pouvant recevoir le connecteur femelle.This document discloses a male electrical connector for a printed circuit board having a plurality of electrical connection pins for traversing the printed circuit board in the mounted state. A first end of a branch of a pin is adapted to enter an associated female electrical connector and its second connection end is intended to be electrically connected to predefined areas of the face of the printed circuit board opposite that which can receive the female connector.

Toutefois, dans la configuration décrite dans ce document, une partie des broches de connexion dépasse une matrice de maintien de ces broches ce qui rend le connecteur assez fragile pour sa manipulation et nécessite une protection supplémentaire du connecteur à l'état monté.However, in the configuration described in this document, a portion of the connection pins protrude from a matrix for holding these pins, which makes the connector fragile enough for its handling and requires additional protection of the connector in the mounted state.

La présente invention vise à pallier ces inconvénients en proposant un connecteur électrique traversant pouvant être monté par une refusion sur une carte à circuit imprimé.The present invention aims to overcome these disadvantages by providing a through electrical connector that can be mounted by reflow on a printed circuit board.

A cet effet, l'invention a pour objet un connecteur électrique mâle pour carte à circuit imprimé, comprenant plusieurs broches de connexion électrique destinées à traverser à l'état monté la carte à circuit imprimé et dont une première extrémité de branchement est apte à entrer dans un connecteur électrique femelle associé et dont la seconde extrémité de connexion est destinée à être reliée électriquement sur des pistes prédéfinies de la face de la carte à circuit imprimé opposée à celle pouvant recevoir le connecteur femelle, les broches étant maintenues en position dans une matrice de maintien en matériau isolant, caractérisé en ce que la seconde extrémité de connexion se prolonge par une portion recourbée entourant partiellement une partie de la matrice de maintien et se terminant par une portion de connexion par refusion s'étendant sensiblement au droit de l'étendue longitudinale des broches.For this purpose, the subject of the invention is a male electrical connector for a printed circuit board, comprising a plurality of electrical connection pins intended to pass through the printed circuit board in the mounted state and of which a first connection end is able to enter. in an associated female electrical connector and whose second connection end is intended to be electrically connected to predefined tracks of the face of the printed circuit board opposite to that which can receive the female connector, the pins being held in position in a matrix holding device made of insulating material, characterized in that the second connection end is extended by a curved portion partially surrounding a portion of the holding matrix and ending with a reflow connection portion extending substantially to the extent of the expanse longitudinal pins.

L'invention a également pour objet une carte à circuit imprimé équipée d'un connecteur tel que décrit ci-dessus.The invention also relates to a printed circuit board equipped with a connector as described above.

D'autres avantages et caractéristiques apparaîtront à la lecture de la description de l'invention, ainsi que des dessins annexés sur lesquels:

  • la figure 1 est une vue en coupe transversale d'un connecteur selon l'invention,
  • la figure 2 est une vue de dessus d'un connecteur selon l'invention, et
  • la figure 3 est une vue de dessus d'une partie d'une carte à circuit imprimé accueillant le connecteur selon l'invention.
Other advantages and characteristics will appear on reading the description of the invention, as well as the appended drawings in which:
  • FIG. 1 is a cross-sectional view of a connector according to the invention,
  • FIG. 2 is a view from above of a connector according to the invention, and
  • Figure 3 is a top view of a portion of a printed circuit board hosting the connector according to the invention.

On se réfère aux figures 1 à 3 pour décrire le connecteur électrique mâle selon l'invention.Referring to Figures 1 to 3 to describe the male electrical connector according to the invention.

La figure 1 montre en coupe transversale un connecteur électrique mâle 1 selon l'invention. Ce connecteur comprend plusieurs broches de connexion électrique 3 et 5 traversant à l'état monté des trous 6 (voir figure 3) d'une carte à circuit imprimé 7 ainsi qu'une embase 9 de connecteur (voir figure 1).Figure 1 shows in cross section a male electrical connector 1 according to the invention. This connector comprises a plurality of electrical connection pins 3 and 5 in the mounted state of the holes 6 (see Figure 3) of a printed circuit board 7 and a connector base 9 (see Figure 1).

Les extrémités libres 11 et 13 des broches 3 et 5, également appelées premières extrémités de branchement, sont aptes à entrer dans un connecteur électrique femelle associé (non représenté sur les figures).The free ends 11 and 13 of the pins 3 and 5, also called first ends of branching, are able to enter an associated female electrical connector (not shown in the figures).

L'autre extrémité 15, 17 également appelée « seconde extrémité de connexion » de chaque broche 3, 5 est destinée à être reliée électriquement sur des plages 18 (voir figure 3) prédéfinies sur la face 19 de la carte à circuit imprimé 7 opposée à celle 21 pouvant recevoir le connecteur femelle.The other end 15, 17 also called "second connection end" of each pin 3, 5 is intended to be electrically connected to the pads 18 (see Figure 3) predefined on the face 19 of the printed circuit board 7 opposite to that 21 can receive the female connector.

Les broches 3,5 sont maintenues en position relative l'une par rapport à l'autre dans une matrice de maintien 23 en matériau isolant.The pins 3.5 are held in relative position relative to each other in a holding matrix 23 of insulating material.

Avantageusement, la seconde extrémité de connexion 15, 17 de chaque broche se prolonge par une portion recourbée 25, 27 entourant partiellement une partie 29, 31 de la matrice de maintien 23 et se terminant par une portion de connexion par refusion 33, 35 s'étendant sensiblement au droit de l'étendue longitudinale des broches 3, 5.Advantageously, the second connection end 15, 17 of each pin is extended by a curved portion 25, 27 partially surrounding a portion 29, 31 of the holding matrix 23 and ending with a reflow connection portion 33, 35 s'. extending substantially to the right of the longitudinal extent of the pins 3, 5.

Par cette disposition matrice - broches, on a constaté une meilleure tenue mécanique du connecteur selon l'invention aussi bien pour la connexion que pour la déconnexion d'un connecteur femelle associé. En effet, il y a un équilibrage des forces grâce à la matrice, ce qui diminue les forces présentes au niveau des plages de connexion 18.By this matrix-pin arrangement, it has been found that the connector according to the invention has a better mechanical strength both for the connection and for the disconnection of an associated female connector. Indeed, there is a balance of forces through the matrix, which reduces the forces present at the connection pads 18.

Comme on le voit sur la figure 1, la matrice 23 est destinée à être montée sur la même face de la carte à circuit imprimé 7 que les portions de connexion par refusion 33, 35 des broches de connexion 3, 5.As seen in FIG. 1, the die 23 is intended to be mounted on the same face of the printed circuit board 7 as the reflow connection portions 33, 35 of the connection pins 3, 5.

A cet effet, la face d'appui 37 de la matrice 23 et la face de la portion 39 de connexion destinée à être en contact avec la carte sont sensiblement alignées.For this purpose, the bearing face 37 of the die 23 and the face of the connecting portion 39 intended to be in contact with the card are substantially aligned.

La matrice 23 est réalisée en un matériau isolant, de préférence en plastique, ayant une bonne tenue en température jusqu'aux températures de refusion, par exemple d'environ 270°C.The matrix 23 is made of an insulating material, preferably plastic, having a good temperature resistance up to reflow temperatures, for example about 270 ° C.

Comme on le voit mieux sur la figure 2, les broches 3 appartiennent à une première rangée de broches tandis que les broches 5 appartiennent à une seconde rangée.As best seen in Figure 2, the pins 3 belong to a first row of pins while the pins 5 belong to a second row.

De préférence, les portions de connexion de la première rangée de broches 3 et celles de la seconde rangée de broches 5 se terminent sur des côtés opposés de la matrice 23 (voir sur la figure 1).Preferably, the connecting portions of the first row of pins 3 and those of the second row of pins 5 terminate on opposite sides of the die 23 (see Figure 1).

Avantageusement, la matrice 23 présente au moins entre deux broches 3 et 5 de deux rangées différentes une protubérance 41 dont la hauteur est au moins égale à l'étendue verticale H de la partie recourbée des broches.Advantageously, the matrix 23 has at least between two pins 3 and 5 of two different rows a protuberance 41 whose height is at least equal to the vertical extent H of the curved portion of the pins.

Cette protubérance 41 forme un point d'appui lors de la fabrication du connecteur en recourbant la tige insérée à force dans la matrice et permet une manipulation plus aisée du connecteur en particulier lors de la dépose en automatique des composants CMS sur la carte à circuit imprimé. De plus, cette protubérance fait office de protection pour les broches.This protuberance 41 forms a fulcrum during manufacture of the connector by bending the rod inserted by force in the die and allows easier handling of the connector especially when automatically removing CMS components on the printed circuit board. In addition, this protuberance acts as protection for the pins.

Il s'est avéré préférentiel de prévoir pour la matrice 23 des pions de positionnement (non représentés) aptes à coopérer avec des logements correspondants ménagés dans la carte à circuit imprimé.It has been found preferable for the matrix 23 to provide positioning pins (not shown) capable of cooperating with corresponding housings formed in the printed circuit board.

Pour une bonne tenue mécanique, les broches 3, 5 sont insérées à force dans la matrice de maintien 23.For good mechanical strength, the pins 3, 5 are forced into the holding die 23.

La figure 3 montre la partie de la carte à circuit imprimé prête à recevoir le connecteur selon l'invention.Figure 3 shows the portion of the printed circuit board ready to receive the connector according to the invention.

On y distingue en particulier les trous 6 pour les broches 3,5 ainsi que les plages prédéfinies 18 de contact prêtes à recevoir de la pâte à souder par refusion.It distinguishes in particular the holes 6 for pins 3.5 and the predefined contact pads 18 ready to receive solder paste by reflow.

Pour réaliser une carte à circuit imprimé avec un connecteur électrique mâle selon l'invention, on procède de la manière suivante :

  • On insère à force dans chaque alvéole de la matrice 23 une tige métallique dont on va recourber l'extrémité de connexion 25, 27 de connexion pour obtenir une forme de broche telle que décrite ci-dessus.
  • Puis on dépose l'ensemble sur la carte à circuit imprimé dont les plages 18 ont été préparées préalablement avec de la pâte à souder.
  • Bien entendu, dans le même temps on dépose aussi tous les autres composants CMS que la carte à circuit imprimé doit accueillir.
  • Enfin, on passe l'ensemble dans un four à refusion.
  • On comprend bien le gain en temps et la diminution du nombre de manipulations de retournement de la carte, ce qui permet de réduire considérablement le prix de revient pour une telle carte avec connecteur traversant mâle, ainsi que l'amélioration de la qualité de soudure, car celle-ci est réalisée par une seule opération pour l'ensemble des composants électroniques, ce qui évite la soudure du connecteur par reprise en vague sélective à la main ou par robot.
To make a printed circuit board with a male electrical connector according to the invention, the procedure is as follows:
  • A metal rod is inserted by force into each cell of the die 23, the connection end 25, 27 of which is going to be curved to obtain a pin shape as described above.
  • Then the assembly is deposited on the printed circuit board whose pads 18 were previously prepared with solder paste.
  • Of course, at the same time we also deposit all the other CMS components that the circuit board must accommodate.
  • Finally, we pass all in a reflow oven.
  • It is easy to understand the gain in time and the reduction in the number of reversal manipulations of the card, which makes it possible to considerably reduce the cost price for such a card with a male through connector, as well as the improvement of the quality of welding, because it is performed by a single operation for all electronic components, which avoids the welding of the connector by selective wave resumption by hand or by robot.
