Description

La présente invention concerne un connecteur mâle basse tension destinée à être enfiché dans un connecteur femelle basse tension comprenant plusieurs broches souples destinées à venir en contact avec le connecteur mâle pour établir un contact électrique entre eux. Le type de connecteur particulièrement concerné par la présente invention est souvent désigné par le terme RJ45 que l'on retrouve fréquemment dans le domaine de la connectique informatique, téléphonique, etc. utilisant des courants basse tension.The present invention relates to a low-voltage male connector intended to be plugged into a low-voltage female connector comprising a plurality of flexible pins intended to come into contact with the male connector in order to establish an electrical contact between them. The type of connector particularly concerned by the present invention is often referred to by the term RJ45 which is frequently found in the field of computer, telephone and other connections. using low voltage currents.

Le connecteur mâle du type RJ45 est connu pour recevoir un cordon constitué de quatre paire de fils conducteurs torsadés que l'on fixe sur des contacts autodénudants respectifs du connecteur mâle RJ45. Par conséquent, le connecteur mâle RJ45 est réalisé avec huit contacts autodénudants présentant chacun une pointe sur laquelle un fil conducteur respectif peut être planté de manière à inciser sa gaine isolante pour réaliser un contact avec l'âme du fil.The RJ45-type male connector is known to receive a cord consisting of four pairs of twisted wires which are fixed on respective insulation displacement contacts of the RJ45 male connector. Therefore, the RJ45 male connector is made with eight insulation displacement contacts each having a tip on which a respective conductor wire can be planted so as to incise its insulating sheath to make contact with the core of the wire.

A l'origine, le connecteur mâle RJ45 a été conçu pour recevoir des câbles en nappe de fils conducteurs parallèles destinés à être percés par les contacts autodénudants du même pas. Par la suite, les conducteurs parallèles en nappe en raison de la mauvaise diaphonie entre les fils ont été remplacés par des paires torsadées susmentionnées. Toutefois, l'utilisation de paires torsadés rend la connexion des câbles beaucoup plus difficiles puisqu'il faut placer manuellement les paires dans le connecteur RJ45. Le contact électrique entre le connecteur mâle et le connecteur femelle équipé de broches souples de contact peut être réalisé directement sur les contacts autodénudants alignés en nappe comme les fils conducteurs, ou sur des broches qui sont reliées électriquement au contacts autodénudants et présentent une zone de contact apte à venir en contact avec les broches souples du connecteur femelle. Dans le premier cas où le contact s'effectue directement sur les contacts autodénudants alignés en nappe, le pas des contacts du connecteur mâle doit être identique à celui du connecteur femelle avec des intervalles normalisés (ISO 88 77). Si l'on veut maintenant utiliser des paires dont les fils sont plus gros, il se produit un décalage entre les contacts autodénudants et les fils rendant impossible la connexion.Originally, the RJ45 male connector was designed to receive ribbon cables of parallel conductors to be pierced by insulation displacement contacts of the same pitch. Subsequently, the parallel ribbon conductors due to poor crosstalk between the wires have been replaced by twisted pairs mentioned above. However, the use of twisted pairs makes the connection of cables much more difficult since it is necessary to manually place the pairs in the RJ45 connector. The electrical contact between the male connector and the female connector equipped with flexible contact pins can be made directly on the insulating contacts aligned in a sheet like the conductive wires, or on pins which are electrically connected to the insulation displacement contacts and have a contact zone. adapted to come into contact with the flexible pins of the female connector. In the first case where the contact is made directly on the self-insulation contacts aligned in a sheet, the pitch of the contacts of the male connector must be identical to that of the female connector with standardized intervals (ISO 88 77). If we now want to use pairs whose son are larger, there is a gap between insulation displacement contacts and son making impossible connection.

En outre, puisque les contacts doivent avoir un pas très serré, il se crée des couplages inductifs qu'il devient indispensable de compenser en terme de diaphonie en croisant judicieusement les broches du connecteur mâle qui font la connexion entre les contacts autodénudants et les broches souples du connecteur femelle. Par conséquent, la conception même du connecteur RJ45 particulièrement au niveau des broches qui font le contact entre les contacts autodénudants et les broches du connecteur femelle est particulièrement compliqué à réaliser et à monter, ce qui induit un coût de fabrication élevée.In addition, since the contacts must have a very tight pitch, it creates inductive couplings that it becomes essential to compensate in terms of crosstalk by judiciously crossing the pins of the male connector that make the connection between the insulation displacement contacts and the flexible pins of the female connector. Therefore, the very design of the RJ45 connector especially at the pins that make the contact between the insulation displacement contacts and the pins of the female connector is particularly complicated to produce and to mount, which induces a high manufacturing cost.

Dans l'art antérieur, le document EP-0 899 833 (D1) décrit une fiche jack constituée de deux boîtiers emboîtables et renfermant un support de lames sur lequel sont montées huit lames. A une de leurs extrémités, les lames forment des contacts au niveau du boîtier, alors qu'à leurs autres extrémités du côté du boîtier, elles forment des contacts autodénudants (CAD).In the prior art, the document EP-0 899 833 (D1) describes a jack plug consisting of two nestable boxes and containing a blade holder on which are mounted eight blades. At one of their ends, the blades form contacts at the housing, while at their other ends on the housing side, they form insulation displacement contacts (ADC).

Il n'y a pas de circuit imprimé dans cette fiche. La connexion électrique est entièrement réalisée par les lames.There is no circuit board in this card. The electrical connection is entirely made by the blades.

D'autre part, le document EP-0 901 201 (D2) décrit un connecteur dans lequel une plaque de circuit imprimé est pourvue de broches à contacts autodénudants (CAD).On the other hand, EP-0 901 201 (D2) discloses a connector in which a printed circuit board is provided with pins with insulation displacement contacts (ADC).

Le circuit imprimé est en outre pourvu de broches de contact sur lesquelles le contact électrique est pris.The printed circuit is further provided with contact pins on which the electrical contact is made.

Dans ce connecteur, le circuit sert de pistes conductrices permettant de réduire la diaphonie, mais pas de contacts électriques.In this connector, the circuit serves as conductive tracks to reduce crosstalk, but no electrical contacts.

En outre, il est à noter que le connecteur dans le document D1 est un connecteur mâle à contacts rigides, alors que le connecteur dans le document D2 est un connecteur femelle à contacts souples.In addition, it should be noted that the connector in the document D1 is a male connector with rigid contacts, while the connector in the document D2 is a female connector with flexible contacts.

La présente invention a pour but de pallier aux inconvénients de l'art antérieur précité en définissant un connecteur mâle basse tension à couplage inductif réduit, pouvant accueillir des fils de section relativement grande et dont la réalisation est extrêmement simple.The present invention aims to overcome the disadvantages of the aforementioned prior art by defining a low-voltage male connector with reduced inductive coupling, which can accommodate relatively large section son and whose implementation is extremely simple.

Pour ce faire, la présente invention propose un connecteur mâle basse tension destiné à s'enficher dans un connecteur femelle basse tension comprenant plusieurs broches souples destinées à venir en contact avec ledit connecteur mâle pour établir un contact électrique entre eux, ledit connecteur mâle comprenant des contacts autodénudants destinés à recevoir chacun un fil conducteur, la connexion électrique entre les broches souples du connecteur femelle et les contacts autodénudants étant réalisée par un circuit imprimé comprenant des pistes conductrices reliant chacune un contact autodénudant à une broche respective. Le contact électrique avec les broches souples du connecteur femelle est donc établi directement sur le circuit imprimé, et non pas sur des broches rapportées, comme c'est le cas dans le document EP-0 901 201. L'utilisation d'un circuit imprimé est particulièrement avantageux car il permet un croisement aisé des pistes conductrices qui sont conventionnellement réalisés dans un connecteur RJ45 par le croisement des broches de contact du connecteur mâle. Dans un circuit imprimé, les croisements de pistes peuvent simplement être réalisés au moyen de via faisant passer les pistes d'un plan conducteur à l'autre du circuit imprimé. En outre, étant donné que les contacts sont très serrés, il se crée des couplages inductifs que l'on peut aisément compenser un terme de diaphonie au moyen d'un circuit amélioré en prévoyant des éléments inductifs et capacitifs permettant justement de compenser la diaphonie. Le circuit imprimé offre donc l'avantage de pouvoir aisément croiser les pistes et de pouvoir aisément réaliser des éléments permettant la compensation de couplage inductif.To do this, the present invention proposes a low-voltage male connector intended to be plugged into a low-voltage female connector comprising a plurality of flexible pins intended to come into contact with said male connector in order to establish an electrical contact between them, said male connector comprising insulation displacement contacts each for receiving a conducting wire, the electrical connection between the flexible pins of the female connector and the insulation displacement contacts being made by a printed circuit comprising conductive tracks each connecting an insulation displacement contact to a respective pin. The electrical contact with the flexible pins of the female connector is therefore established directly on the printed circuit, and not on pins reported, as is the case in the document EP-0 901 201. The use of a printed circuit is particularly advantageous because it allows easy crossing of the conductive tracks that are conventionally made in an RJ45 connector by crossing the contact pins of the male connector. In a printed circuit, the crossings of tracks can simply be achieved by means of passing the tracks from one conductive plane to the other of the printed circuit. In addition, because the contacts are very tight, it creates inductive couplings that can easily compensate for a crosstalk term by means of an improved circuit by providing inductive and capacitive elements to compensate for crosstalk. The printed circuit thus offers the advantage of being able to cross the tracks easily and to be able to easily produce elements allowing inductive coupling compensation.

En outre, le circuit imprimé peut servir de support pour la fixation des contacts autodénudants. Ainsi, il est aisé de répartir les contacts autodénudants sur le circuit imprimé de manière à faciliter le câblage.In addition, the printed circuit can serve as a support for fixing the insulation displacement contacts. Thus, it is easy to distribute the insulation displacement contacts on the printed circuit to facilitate wiring.

Selon une caractéristique particulièrement intéressante de la présente invention, le circuit imprimé comprend des zones de contact destinées à venir en contact de glissement avec les broches souples à mesure que l'on enfiche le connecteur mâle dans le connecteur femelle dont les broches souples fléchissent et changent d'orientation, lesdites zones étant prévues sur une partie arrondie ou coudée du circuit imprimé. Ainsi, le circuit imprimé sert avantageusement de point de contact électrique avec les broches souple du connecteur femelle. Il faut savoir que les broches souples du connecteur femelle effectuent un changement d'orientation dans l'espace de l'ordre de 15° lors de l'enfichage du connecteur mâle pour assurer un contact électrique par une action mécanique élastique des broches femelle sur les zones de contacts du connecteur mâle. Ainsi, le point de contact entre les broches du connecteur femelle et les zones de contact du connecteur mâle est un contact glissant. Afin d'éviter que les broches ne s'usent par frottement en raison des connexions répétées, il est préférable voire nécessaire que le point de contact des broches femelle avec les zones de contact du connecteur mâle soit arrondi pour offrir une qualité de surface réduisant l'abrasion. Par conséquent, le point de contact des broches souples du connecteur femelle se déplace lors de l'enfichage sur cette surface arrondie définie par les zones de con tact du circuit imprimé. En prévoyant directement ces zones de contact arrondies au niveau du circuit imprimé, on élimine une pièce supplémentaire réalisant cette fonction.According to a particularly advantageous feature of the present invention, the printed circuit comprises contact areas intended to come into sliding contact with the flexible pins as the male connector is plugged into the female connector whose flexible pins flex and change. orientation, said zones being provided on a rounded or bent part of the printed circuit. Thus, the printed circuit advantageously serves as a point of electrical contact with the flexible pins of the female connector. It should be known that the flexible pins of the female connector effect a change of orientation in the space of about 15 ° when plugging the male connector to ensure electrical contact by an elastic mechanical action of the female pins on the pins. contact areas of the male connector. Thus, the point of contact between the pins of the female connector and the contact areas of the male connector is a sliding contact. In order to prevent the pins from being worn out by friction due to repeated connections, it is preferable or even necessary that the contact point of the female pins with the contact areas of the male connector be rounded to provide a surface quality reducing the 'abrasion. Consequently, the contact point of the flexible pins of the female connector moves during insertion on this rounded surface defined by the contact areas of the printed circuit. By providing these rounded contact areas directly at the level of the printed circuit, an additional piece performing this function is eliminated.

Selon une première forme de réalisation, le circuit imprimé comprend un substrat rigide, ladite partie arrondie étant réalisée sur un bord dudit substrat, par exemple par formage ou estampage. En variante, le circuit imprimé comprend un substrat rigide, ladite partie coudée étant réalisée par pliage du substrat sensiblement au niveau d'un bord. Le substrat rigide du circuit imprimé ne remplit alors pas qu'une fonction électrique, mais également une fonction mécanique de contact de glissement.According to a first embodiment, the printed circuit comprises a rigid substrate, said rounded portion being formed on an edge of said substrate, for example by forming or stamping. Alternatively, the printed circuit comprises a rigid substrate, said bent portion being made by folding the substrate substantially at an edge. The rigid substrate of the printed circuit then not only fulfills an electrical function, but also a sliding contact mechanical function.

Selon une autre forme de réalisation, le circuit imprimé comprend un substrat rigide et une feuille souple, ladite partie arrondie ou coudée étant réalisée par une courbure de ladite feuille souple. On se sert ici de la souplesse de la feuille pour créer cette partie arrondie.According to another embodiment, the printed circuit comprises a rigid substrate and a flexible sheet, said rounded or bent portion being formed by a curvature of said flexible sheet. The flexibility of the sheet is used here to create this rounded part.

Avantageusement, la feuille souple comprend une piste additionnelle en contact électrique avec un élément de continuité de masse destinée à venir en contact électrique avec une borne de masse située dans le connecteur femelle.Advantageously, the flexible sheet comprises an additional track in electrical contact with a ground continuity element intended to come into electrical contact with a ground terminal located in the female connector.

Selon une autre caractéristique, le circuit imprimé est pourvu au niveau desdites zones de contact d'un organe de guidage, avantageusement sous la forme d'un peigne, servant à guider les broches souples sur lesdites zones de contact. Et dans le cas où le connecteur mâle comprend un boîtier métallique ou métallisé permettant un blindage du connecteur, ledit organe de guidage est de préférence électriquement isolant pour éviter tout court-circuit entre le boîtier du connecteur mâle et les broches souples de contact du connecteur femelle.According to another characteristic, the printed circuit is provided at said contact areas with a guide member, advantageously in the form of a comb, for guiding the flexible pins on said contact areas. And in the case where the male connector comprises a metal or metallized housing for shielding the connector, said guide member is preferably electrically insulating to avoid any short circuit between the housing of the male connector and the flexible contact pins of the female connector. .

Le connecteur mâle basse tension qui va maintenant être décrit est un connecteur du type RJ 45. La conception particulière de ce connecteur ne doit pas être considérée limitative, mais au contraire peut subir de nombreuses variantes sans pour autant sortir du cadre de l'invention.The low-voltage male connector which will now be described is a connector of the RJ 45 type. The particular design of this connector must not be considered as limiting, but on the contrary can undergo numerous variants without departing from the scope of the invention.

Le connecteur représenté sur les figures 1, 2 , 3, 4, 5, 6 et 7 présente une structure générale sensiblement identique. Il est constitué essentiellement de cinq éléments constitutifs, à savoir un corps 1, un support de contact autodénudant 2, une plaque de circuit imprimé 3, un capot organisateur 4 et un étrier de continuité de masse 5.The connector shown in Figures 1, 2, 3, 4, 5, 6 and 7 has a substantially identical overall structure. It consists essentially of five constituent elements, namely a body 1, an insulation displacement contact carrier 2, a printed circuit board 3, an organizer cover 4 and a ground continuity stirrup 5.

Le corps 1 qui est en général réalisé en matériau plastique moulé, comprend un bâti 10 et un appendice d'enfichage 11 destiné à être enfiché dans le connecteur femelle correspondant dans lequel il est maintenu par encliquetage à l'aide d'une languette souple d'encliquetage 12. Le bâti 10 définit un espace intérieur dans lequel sont disposés la plaque de circuit imprimé 3 et le support de contact autodénudant 2. Le bâti 1 est fermé au moyen du couvercle organisateur 4 dont la fonction est la répartition spatiale des fils conducteurs du câble de raccordement. En effet, pour faciliter l'insertion des fils conducteurs dans les contacts autodénudants 21 respectifs, on se sert de ce capot qui est conçu pour maintenir les fils conducteurs du câble selon une distribution spatiale permettant leur insertion dans les fentes des contacts autodénudants 21. Ainsi, l'opérateur chargé du câblage commence d'abord par disposer les fils individuellement dans le capot organisateur. A l'état monté, la plaque de circuit imprimé 3 et le support de contacts autodénudants 2 sont déjà montés à l'intérieur du bâti 10 et il suffit alors de mettre le capot 4 en place et de pousser pour réaliser l'incision des fils conducteurs à l'intérieur des fentes des contacts autodénudants 21. A l'état monté représenté sur la figure 3, le bâti contient le support de contact autodénudant 2 et une partie de plaque de circuit imprimé 3, en l'occurrence la partie 334 la plus large alors que la partie 35 plus étroite s'étend à l'intérieur de l'appendice d'enfichage 11.The body 1, which is generally made of molded plastics material, comprises a frame 10 and a plug-in appendix 11 intended to be plugged into the corresponding female connector in which it is held by snapping with the aid of a flexible tongue. The frame 10 defines an interior space in which the printed circuit board 3 and the insulation displacement contact holder 2 are arranged. The frame 1 is closed by means of the organizer cover 4 whose function is the spatial distribution of the conductive wires. connecting cable. Indeed, to facilitate the insertion of the conductive son in the respective insulation displacement contacts 21, this cover is used which is designed to maintain the conductive son of the cable in a spatial distribution for their insertion into the slots of insulation displacement contacts 21. Thus , the operator in charge of the wiring starts by arranging the wires individually in the organizing hood. In the mounted state, the printed circuit board 3 and the insulation displacement contact holder 2 are already mounted inside the frame 10 and it is then sufficient to put the cover 4 in place and push to make the incision of the wires. In the assembled state shown in FIG. 3, the frame contains the insulation displacement contact carrier 2 and a printed circuit board portion 3, in this case the portion 334, wider while the narrower portion 35 extends inside the plug-in appendix 11.

Une caractéristique intéressante de l'invention réside dans le fait d'utiliser une plaque de circuit imprimé 2 pour réaliser la liaison électrique entre les contacts autodénudants21 et les broches souples de contact (représentées schématiquement en 6) du connecteur femelle. En effet, comme dans un connecteur RJ45 classique, les zones de contact 331 du connecteur mâle destinées à venir en contact électrique avec les broches souples 6 du connecteur femelle sont situées à l'extrémité inférieure de l'appendice de l'enfichage 11, tel que représenté sur les figures 1 et 2. Ces zones de contact 331 (fig. la) sont alignées côte à côte, généralement au nombre de huit, correspondant à celles des broches souples du connecteur femelle.An interesting feature of the invention lies in the fact of using a printed circuit board 2 to make the electrical connection between the insulation displacement contacts 21 and the flexible contact pins (shown schematically at 6) of the female connector. Indeed, as in a conventional RJ45 connector, the contact areas 331 of the male connector intended to come into electrical contact with the flexible pins 6 of the female connector are located at the lower end of the appendix of the plug-in 11, such as 1 and 2. These contact zones 331 (FIG 1a) are aligned side by side, generally eight in number, corresponding to those of the flexible pins of the female connector.

Alors que dans l'art antérieur, on utilise des broches pour réaliser la liaison électrique entre les contacts autodénudants 21 et les broches souples 6 dudit connecteur femelle, on utilise ici selon l'invention une plaque de circuit imprimé 3 pour réaliser cette liaison électrique. Pour cela, la plaque de circuit imprimé 3 comprend plusieurs pistes conductrices 335, généralement au nombre de huit, qui relient respectivement un contact autodénudant 21 à une broche souple 6 du connecteur femelle. Comme on peut le voir clairement sur la figure 1, la plaque de circuit imprimé 3 qui se présente ici sous la forme d'un substrat rigide 30, est réalisée avec des trous de connexion 32 dans lesquels viennent se loger des plots de contact 22 réalisés avantageusement de manière monobloc avec les contacts autodénudants 21. En pratique, le support de contacts autodénudants 2 comprend une structure 20 en plastique moulé à travers laquelle s'étendent les contacts autodénudants 21 qui se terminent par les plots de contact 22 qui font saillie sur la face opposée de la structure 20 de manière à pouvoir être insérés dans les trous de connexion 32 ménagés dans la plaque de circuit imprimé 3. Ainsi, un contact électrique simple est réalisé entre les contacts autodénudants 21 et la plaque de circuit imprimé 3. En outre, en raison de la surface relativement importante de la plaque de circuit imprimé 3, il est plus facile d'organiser spatialement la distribution des contacts autodénudants 21 de manière à faciliter le câblage au moyen du capot organisateur 4.While in the prior art, pins are used to make the electrical connection between the insulation displacement contacts 21 and the flexible pins 6 of said female connector, it is used here according to the invention a printed circuit board 3 to achieve this electrical connection. For this, the printed circuit board 3 comprises several conductive tracks 335, generally eight in number, which respectively connect an insulation displacement contact 21 to a flexible pin 6 of the female connector. As can be seen clearly in FIG. 1, the printed circuit board 3, which is here in the form of a rigid substrate 30, is made with connection holes 32 in which contact pads 22 are made to fit. advantageously in a monobloc manner with the insulation displacement contacts 21. In practice, the insulation displacement contact holder 2 comprises a molded plastic structure 20 through which the insulation displacement contacts 21 extend, which terminate in the contact pads 22 which protrude from the opposite side of the structure 20 so as to be inserted into the connection holes 32 formed in the printed circuit board 3. Thus, a simple electrical contact is made between the insulation displacement contacts 21 and the printed circuit board 3. because of the relatively large area of the printed circuit board 3, it is easier to spatially organize the contact distribution s self-stripping 21 so as to facilitate the wiring by means of the organizer cover 4.

Selon une autre caractéristique particulièrement intéressante de l'invention, le bord 33 de la plaque de circuit imprimé 3 est réalisé de manière arrondie comme on peut mieux le voir sur la figure la et la figure 4. C'est précisément dans cette partie arrondie de la plaque de circuit imprimé 3 que sont situées les zones de contact 331 destinées à venir en contact avec des broches souples 6 du connecteur femelle. Comme cela a été décrit précédemment, lors de l'enfichage du connecteur mâle, les broches souples du connecteur femelle subissent un fléchissement qui a pour effet de changer leur orientation spatiale et donc leur point de contact avec la zone de contact du connecteur mâle. En réalisant les zones de contact sur la partie arrondie, les broches souples du connecteur femelle peuvent glisser pratiquement sans frottement sur les zones de contact, ce qui retarde l'usure des connecteurs.According to another particularly advantageous feature of the invention, the edge 33 of the printed circuit board 3 is made in a rounded manner, as can best be seen in FIG. 1a and FIG. 4. It is precisely in this rounded part of FIG. the printed circuit board 3 that are located contact areas 331 intended to come into contact with flexible pins 6 of the female connector. As has been described above, when plugging the male connector, the flexible pins of the female connector undergo a deflection which has the effect of changing their spatial orientation and therefore their point of contact with the contact area of the male connector. By realizing the contact areas on the rounded portion, the flexible pins of the female connector can slide virtually frictionlessly on the contact areas, which delays the wear of the connectors.

L'utilisation d'une plaque de circuit imprimé 3 pour réaliser la liaison électrique entre les contacts autodénudants 21 et les broches souples 6 du connecteur femelle présente plusieurs avantages : premièrement, il est facile d'établir un contact électrique entre les contacts autodénudants 21 et la plaque de circuit imprimé 3 en raison de sa surface étendue. Deuxièmement, il est facile de réaliser des pistes conductrices dans le circuit imprimé 3 qui répondent aux exigences de diaphonie en prévoyant des éléments capacitifs et inductifs dans le circuit imprimé et en utilisant des via pour effecteur des croisements de pistes conductrices. Troisièmement, on peut directement se servir de la plaque de circuit imprimé grâce à son profil arrondi au niveau de son bord 33 pour réaliser des zones de contacts qui répondent parfaitement aux exigences liées aux changements d'orientation des broches souples du connecteur femelle lors de l'enfichage du connecteur mâle.The use of a printed circuit board 3 to make the electrical connection between the insulation displacement contacts 21 and the flexible pins 6 of the female connector has several advantages: firstly, it is easy to establish an electrical contact between the insulation displacement contacts 21 and the printed circuit board 3 because of its extended surface. Secondly, it is easy to make conductive tracks in the printed circuit 3 that meet the crosstalk requirements by providing capacitive and inductive elements in the printed circuit and using via to effect crossings of conductive tracks. Thirdly, the printed circuit board can be used directly by virtue of its rounded profile at its edge 33 for producing contact areas which perfectly meet the requirements related to changes of orientation of the flexible pins of the female connector during the first time. Plug in the male connector.

Dans la forme de réalisation des figures 1, 2 et 4, les zones de contact 331 sont réalisés dans une partie arrondie du bord 33 de la plaque de circuit imprimé. L'arrondi peut être réalisé par n'importe quelle technique comme le formage ou l'estampage.In the embodiment of Figures 1, 2 and 4, the contact areas 331 are formed in a rounded portion of the edge 33 of the printed circuit board. Rounding can be achieved by any technique such as forming or stamping.

En se référant maintenant à la figure 5, le connecteur mâle représenté diffère de celui de la figure 4 en ce que les zones de contact 331 sont situés sur une partie courbée ou coudée du circuit imprimé 3. Cette forme de réalisation est totalement équivalente de celle de la figure 4 en ce que le bord du circuit imprimé 3 forme une surface de contact permettant un contact continu des broches souples 6 lors de leur changement d'orientation.Referring now to FIG. 5, the male connector shown differs from that of FIG. 4 in that the contact zones 331 are situated on a curved or bent portion of the printed circuit 3. This embodiment is totally equivalent to that of FIG. of Figure 4 in that the edge of the printed circuit 3 forms a contact surface for continuous contact of the flexible pins 6 during their change of orientation.

On peut maintenant à se référer à la figure 6 qui montre une troisième forme de réalisation du circuit imprimé 3. Dans ce cas, le circuit imprimé n'est pas simplement constitué d'un substrat rigide comme c'est le cas dans les formes de réalisation des figures 4 et 5, mais il est en outre complété par une feuille mince souple 35 qui ensemble avec le substrat 30 forme la plaque de circuit imprimé. Le substrat rigide 30 est entièrement contenue à l'intérieur du bâti 10 du corps 1 alors que la feuille souple 35 s'étend du bâti 10 à l'intérieur de l'appendice de l'affichage 11. Les zones de contact 331 sont ici définie au niveau d'un coude 33 de la feuille souple 35 réalisée par pliage sur elle-même. On se sert ici de la souplesse de la feuille 35 pour réaliser la partie arrondie définissant les zones de contact. En outre, la feuille 35 s'étend au-delà du coude 3 pour venir en contact de la cage de continuité de masse 5 également représentée sur les figures 1 et 2. Pour maintenir la feuille en contact avec la cage de continuité de masse, l'appendice d'enfichage 11 est pourvu d'une patte élastique 15 qui presse la feuille 35 contre une paroi de la cage de continuité de masse 5. Pour réaliser la liaison électrique, la feuille souple 3 est formée avec une piste additionnelle dont la zone de contact s'étend jusque dans la partie de la feuille coincée entre la patte 15 et la cage 5. Une fois enfichée dans le connecteur femelle, la cage 5 réalisé un contact électrique avec une broche du connecteur femelle pour réaliser la continuité de masse.It is now possible to refer to FIG. 6, which shows a third embodiment of the printed circuit board 3. In this case, the printed circuit does not simply consist of a rigid substrate, as is the case in embodiment of Figures 4 and 5, but is further supplemented by a flexible thin sheet 35 which together with the substrate 30 forms the printed circuit board. The rigid substrate 30 is entirely contained within the frame 10 of the body 1 while the flexible sheet 35 extends from the frame 10 inside the appendix of the display 11. The contact areas 331 are here defined at a bend 33 of the flexible sheet 35 made by folding on itself. The flexibility of the sheet 35 is used here to achieve the rounded portion defining the contact areas. In addition, the sheet 35 extends beyond the bend 3 to come into contact with the earth continuity cage 5 also shown in Figures 1 and 2. To keep the sheet in contact with the ground continuity cage, the plugging appendix 11 is provided with an elastic tab 15 which presses the sheet 35 against a wall of the earth continuity cage 5. To make the electrical connection, the flexible sheet 3 is formed with an additional track whose contact area extends into the portion of the sheet wedged between the lug 15 and the cage 5. Once plugged into the female connector, the cage 5 made electrical contact with a pin of the female connector to achieve the continuity of mass .

En se référant maintenant à la figure 7, qui montre le connecteur selon l'invention de dessus, on voit que l'appendice d'enfichage 11 est pourvu d'une pièce 13 qui réalise un peigne de guidage 14 qui sépare les zones de contact et qui permet de guider les broches souples 6 du connecteur femelle sur les zones de contact 331 de la plaque de circuit imprimé 3. Dans le cas où le corps 1, et éventuellement le capot organisateur 4, sont réalisés en métal ou en plastique métallisé, il est avantageux et même nécessaire de réaliser le peigne 14 en plastique non métallisé afin d'éviter tout court-circuit entre le corps 1 et le connecteur femelle lors de l'enfichage.Referring now to FIG. 7, which shows the connector according to the invention from above, it can be seen that the insertion appendix 11 is provided with a part 13 which produces a guide comb 14 which separates the contact zones. and which makes it possible to guide the flexible pins 6 of the female connector to the contact areas 331 of the printed circuit board 3. In the case where the body 1, and possibly the organizer cover 4, are made of metal or metallized plastic, it is advantageous and even necessary to make the comb 14 of non-metallized plastic to avoid any short circuit between the body 1 and the female connector during plugging.
