Description

CONTACT ELECTRIQUE A PATTE DE RETENTION RAPPORTEE ELECTRIC CONTACT WITH REPORTED RETENTION LEG
La présente invention concerne un contact électrique à patte de rétention rapportée.The present invention relates to an electrical contact with retention tab reported.
La rétention des contacts électriques dans les modules porte contacts de connecteurs électriques est traditionnellement réalisée soit par des linguets plastiques issus du module et venant en appui contre un épaulement du contact électrique soit par une patte ressort découpée pliée dans le flan réalisant le contact ou encore par une patte ressort découpée pliée sur une cage ressort rapportée sur le contact.The retention of the electrical contacts in the contact module modules of electrical connectors is traditionally carried out either by plastic latches coming from the module and bearing against a shoulder of the electrical contact or by a cut spring tab folded in the blank making the contact or by a cut spring tab folded on a spring cage attached to the contact.
La première solution décrite par exemple dans le document FR 2 678 779 A1 oblige à réaliser un moule complexe pour mouler le linguet plastique et, afin d'offrir une force de rétention suffisante, de réaliser un linguet suffisamment épais ce qui limite la possibilité de réduire le pas entre contacts et entre rangées de contacts dans le module porte contacts alors que le contact, préférablement en alliage cuivreux compatible avec les pressions de contact nécessaire dans les applications de contacts de petites dimensions, permettrait de réduire la taille dudit contact et donc de réduire le pas entre contacts et entre rangées.The first solution described, for example, in document FR 2 678 779 A1 makes it necessary to produce a complex mold for molding the plastic pawl and, in order to provide a sufficient retention force, to produce a pawl that is sufficiently thick, which limits the possibility of reducing the step between contacts and between rows of contacts in the contact holder module while the contact, preferably cuprous alloy compatible with the contact pressures required in small contact applications, would reduce the size of said contact and therefore reduce the step between contacts and between rows.
La deuxième solution décrite par exemple dans le document US 5 971The second solution described for example in document US 5 971
816A oblige à choisir un matériau suffisamment raide pour le contact afin de permettre à la patte de rétention de supporter des efforts d'extraction importants ce, au détriment de sa conductibilité ou au détriment de la simplicité de réalisation du contact, ce qui en outre complique considérablement les outils de découpe.816A makes it necessary to choose a sufficiently stiff material for the contact in order to allow the retention lug to withstand significant extraction efforts, to the detriment of its conductivity or to the detriment of the simplicity of making the contact, which furthermore complicates considerably cutting tools.
La troisième solution dont un exemple est décrit dans le document WOThe third solution, an example of which is described in the document WO
99/41807 A1 accroît l'encombrement du contact, ce qui va à rencontre de la possibilité de réduire le pas entre contacts et entre rangées, ou conduit à utiliser des feuillards de très faible épaisseur ce qui complique la réalisation et l'assemblage du contact et n'est pas favorable en terme de capacité en courant.99/41807 A1 increases the size of the contact, which goes against the possibility of reducing the pitch between contacts and between rows, or leads to the use of strips of very small thickness which complicates the production and assembly of the contact and is not favorable in terms of current capacity.
Dans le but de réduire le pas entre contacts tout en préservant la rétention des contacts dans les porte contacts, la présente invention propose un contact de faible dimensionnel et proposant une tenue mécanique excellente. Pour cela la présente invention propose un contact électrique comportant un corps principal et une patte de rétention du contact dans un alvéole d'un module porte contact caractérisé en ce que la patte de rétention est réalisée à partir d'une lamelle rapportée sur une paroi du corps principal.In order to reduce the pitch between contacts while preserving the retention of the contacts in the contact holders, the present invention provides a low dimensional contact and offering excellent mechanical strength. For this purpose, the present invention proposes an electrical contact comprising a main body and a contact retention tab in a cell of a contact holder module characterized in that the retaining lug is made from a plate attached to a wall of the main body.
Avantageusement, la lamelle comporte au moins une plaquette de solidarisation de la lamelle sur la paroi et une lame ressort inclinée par rapport à la plaquette et formant ladite patte de rétention.Advantageously, the blade comprises at least one plate for securing the lamella on the wall and a leaf spring inclined relative to the plate and forming said retaining tab.
D'autres caractéristiques et avantages de l'invention seront apparents à la lecture de la description qui va suivre d'un exemple de réalisation non limitatif de l'invention en référence aux dessins qui représentent: en figure 1 : une vue en perspective trois quart face d'un contact et d'une lamelle pourvue d'une patte de rétention selon l'invention ; en figure 2: le contact de la figure 1 avec la lamelle en position sur le contact; en figure 3: le contact de la figure 1 vu sous un autre angle en regard d'une coupe d'un détail d'un alvéole de réception du contact. Le contact électrique 1 selon l'exemple représenté en figure 1 comporte une partie arrière 19 de réception d'un câble électrique 20 et un corps principal 2 qui selon l'exemple constitue une partie avant du contact sous forme d'une cage de forme générale parallélépipédique.Other features and advantages of the invention will become apparent on reading the following description of a nonlimiting exemplary embodiment of the invention with reference to the drawings which show: in FIG. 1: a three quarter perspective view face of a contact and a slat provided with a retention lug according to the invention; in FIG. 2: the contact of FIG. 1 with the lamella in position on the contact; in Figure 3: the contact of Figure 1 seen at another angle facing a section of a detail of a cell receiving the contact. The electrical contact 1 according to the example shown in Figure 1 comprises a rear portion 19 for receiving an electrical cable 20 and a main body 2 which according to the example constitutes a front portion of the contact in the form of a generally shaped cage cuboid.
La cage selon l'exemple enserre une lame de contact pour réaliser un contact électrique avec un contact broche complémentaire connu en soi.The cage according to the example encloses a contact blade to make electrical contact with a complementary pin contact known per se.
Le contact est optimisé en fonction de sa conductivité et de la raideur nécessaire de la lame de contact pour obtenir une pression de contact adaptée aux applications souhaitées.The contact is optimized according to its conductivity and the necessary stiffness of the contact blade to obtain a contact pressure adapted to the desired applications.
La cage se referme par un rabat 22 et comporte des arêtes longitudinales arrondies.The cage is closed by a flap 22 and has rounded longitudinal edges.
Le contact selon l'invention comporte une patte de rétention 3, réalisée à partir d'une lamelle 5 réalisée dans un feuillard métallique choisi de manière à assurer la résistance à la rupture et l'effet ressort désiré. La lamelle est rapportée sur une paroi 6 du corps du contact selon l'exemple de la figure 2. Selon l'exemple, la lamelle 5 comporte au moins une plaquette 7, 8 de solidarisation de la lamelle sur la paroi 6 et une lame ressort inclinée par rapport à la plaquette 7, 8 et formant ladite patte de rétention 3 destinée à retenir le contact contre un épaulement 18 de l'alvéole 16 représentée schématiquement en figure 3.The contact according to the invention comprises a retention lug 3, made from a strip 5 made in a metal strip chosen so as to ensure the breaking strength and the desired spring effect. The strip is attached to a wall 6 of the body of the contact according to the example of Figure 2. According to the example, the strip 5 comprises at least one plate 7, 8 for securing the strip on the wall 6 and a leaf spring inclined relative to the plate 7, 8 and forming said retaining lug 3 for holding the contact against a shoulder 18 of the cell 16 shown schematically in FIG.
La lamelle 5 selon l'exemple comporte deux plaquettes 7 et 8 reliées par un pontet 9 pour permettre aisément son positionnement sur la paroi 6 supérieure de la cage parallélépipédique.The strip 5 according to the example comprises two plates 7 and 8 connected by a bridge 9 to easily allow its positioning on the upper wall 6 of the parallelepiped cage.
La patte de rétention 3 est découpée dans la lamelle parallèlement au pontet, le pontet maintenant les plaquettes en alignement.The retention lug 3 is cut in the lamella parallel to the bridge, the bridge holding the plates in alignment.
Avantageusement, les deux plaquettes 7, 8 sont pliées en sorte de réaliser, à partir du pontet 9, un flanc rabattu qui s'étend le long de la patte de rétention 3. Le flanc rabattu protège la lame formant la patte de rétention 3 et évite que des corps étrangers viennent se loger entre la lame et le corps du contact.Advantageously, the two plates 7, 8 are folded so as to produce, from the bridge 9, a flanged flank extending along the retention lug 3. The flank flank protects the blade forming the retention lug 3 and prevents foreign bodies from being lodged between the blade and the body of the contact.
La lamelle 5 est préférablement soudée, par exemple par soudure laser, sur le corps du contact et selon la figure 2 deux points de soudure 10, 11 sont prévus.The strip 5 is preferably welded, for example by laser welding, on the body of the contact and according to Figure 2 two soldering points 10, 11 are provided.
D'autres moyens pour solidariser la lamelle sur le contact peuvent être utilisés comme la réalisation de pattes serties sur le corps.Other means for securing the lamella on the contact can be used as the realization of legs crimped on the body.
La lamelle (5) et le corps principal (2) du contact selon l'invention sont avantageusement réalisés dans des matériaux différents, ce qui a pour avantage de permettre d'optimiser séparément le choix des matériaux utilisés d'une part pour le corps et d'autre part pour la patte, aussi bien en ce qui concerne leur nature que leur épaisseur, en fonction de leur usage. Le matériau utilisé pour le corps, par exemple un alliage à base de cuivre est choisi pour privilégier la conductivité électrique, le matériau utilisé pour la patte de rétention privilégiant les propriétés élastiques et la résistance à la rupture pour offrir une bonne force de rétention. Avantageusement le choix d'un matériau ayant une forte résistance à la rupture et un fort module d'élasticité, permet d'obtenir les caractéristiques requises avec un feuillard de faible épaisseur, ce qui permet de réduire les dimensions du contact. Par exemple la lamelle peut être en acier.The strip (5) and the main body (2) of the contact according to the invention are advantageously made of different materials, which has the advantage of making it possible to optimize separately the choice of materials used on the one hand for the body and on the other hand for the paw, as well in regard to their nature as their thickness, according to their use. The material used for the body, for example a copper-based alloy is chosen to favor the electrical conductivity, the material used for the retention tab favoring the elastic properties and the breaking strength to provide a good retention force. Advantageously, the choice of a material having a high tensile strength and a high modulus of elasticity makes it possible to obtain the characteristics required with a thin strip, which makes it possible to reduce the dimensions of the contact. For example, the blade may be steel.
En outre, les dimensions du contact restent réduites et la quantité de matière utilisées pour réaliser la patte de rétention reste limitée.In addition, the dimensions of the contact remain reduced and the amount of material used to make the retention tab remains limited.
Selon les applications et en particulier dans les applications de connecteurs automobiles, un moyen 17 de verrouillage secondaire du contact dans l'alvéole peut être prévu pour sécuriser le verrouillage des contacts dans les alvéoles. Selon l'exemple représenté plus particulièrement en figure 3, le moyen 17 de verrouillage secondaire est réalisé par un barreau transversal à l'alvéole, la cage comprenant un épaulement 13 de réception du barreau, repéré aux figures 1 et 2, contre lequel s'appuie le barreau. Dans ce cas la patte de rétention 3 est un moyen d'encliquetage et de rétention du contact dans l'alvéole constituant de verrouillage primaire du contact dans l'alvéole.According to the applications and in particular in automotive connector applications, a means 17 for secondary locking of the contact in the cell may be provided to secure the locking of the contacts in the cells. According to the example shown more particularly in FIG. 3, the secondary locking means 17 is made by a transverse bar at the cell, the cage comprising a shoulder 13 for receiving the bar, identified in FIGS. 1 and 2, against which press the bar. In this case the retaining lug 3 is a means for detent and retention of the contact in the cell constituting primary locking of the contact in the cell.
Pour respecter le positionnement angulaire du contact dans l'alvéole et assurer son maintien angulaire, le contact comprend des moyens 14, 15 de détrompage à l'insertion du contact dans l'alvéole 16 constitués selon l'exemple par le mur de protection 14 et un bossage 15 réalisé sur un flanc de la cage.In order to respect the angular positioning of the contact in the cell and to ensure its angular retention, the contact comprises means 14, 15 of keying at the insertion of the contact in the cell 16 constituted in the example by the protective wall 14 and a boss 15 made on a side of the cage.
L'invention n'est pas limitée aux exemples représentés et notamment l'invention s'applique indifféremment à un contact femelle ou à un contact mâle et il peut être prévu plusieurs pattes de rétention 3. The invention is not limited to the examples shown and in particular the invention applies equally to a female contact or to a male contact and it can be provided several retention tabs 3.
