Abstract
Description
La présente invention concerne un procédé de fabrication d'une bande de lamelles de contact électrique pour un connecteur électrique, lesdites lamelles étant réunies à leurs extrémités par deux bandes latérales continues, les lamelles étant sorties du plan desdites bandes latérales par torsion autour de leur axe longitudinal, perpendiculaire à la longueur de la bande.The present invention relates to a method of manufacturing a strip of electrical contact strips for an electrical connector, said strips being joined at their ends by two continuous lateral strips, the strips being taken out of the plane of said lateral strips by twisting around their axis. longitudinal, perpendicular to the length of the strip.
Une telle bande de lamelles de contact électrique est utilisée dans un connecteur électrique comportant deux pièces, liées respectivement à l'un et à l'autre des organes à relier électriquement, la bande étant un organe intermédiaire de contact assurant un contact élastique et liée à l'une des deux pièces. Le connecteur peut être plan et comporter deux plaques de contact entre lesquelles est placée la bande, liée à l'une des plaques, ou bien constituer un connecteur cylindrique coaxial comportant une partie mâle et une partie femelle, l'une des deux parties comportant un logement pour la bande.Such a strip of electrical contact strips is used in an electrical connector comprising two parts, linked respectively to one and to the other of the members to be electrically connected, the strip being an intermediate contact member ensuring elastic contact and linked to one of the two rooms. The connector can be flat and include two contact plates between which the strip is placed, linked to one of the plates, or else constitute a coaxial cylindrical connector comprising a male part and a female part, one of the two parts comprising a housing for the band.
L'invention s'applique en particulier, bien que non limitativement, pour les contacts de passage de courants permanents dans l'appareillage haute et moyenne tension.The invention applies in particular, although not limitatively, for the contacts for the passage of permanent currents in the high and medium voltage equipment.
Le document FR 2 339 259 décrit, en relation avec les fig. 7, 10 et 11 du document, une bande de lamelles de contact électrique d'un type tel que défini ci-dessus. Dans ce document, la bande de lamelles est en un matériau conducteur électrique ou non conducteur et les lames sont revêtues dans leur partie centrale par une couche d'un matériau électriquement conducteur qui enveloppe les deux bords de chaque lame. On peut donc séparer, grâce à cette disposition, les deux fonctions nécessaires de contact élastique et de bonne conductivité électrique. En effet, le matériau de la bande qui doit assurer un contact élastique à la façon d'un ressort n'a pas nécessairement de bonnes qualités de conductivité électrique. Cependant, la bande de lamelles du document ci-dessus, dont chaque lamelle comporte une couche d'un matériau électriquement conducteur enveloppant les deux bords de la lamelle, n'est pas facile à fabriquer, chaque lamelle devant être individuellement revêtue de sa couche conductrice.The document FR 2 339 259 describes, in relation to FIGS. 7, 10 and 11 of the document, a strip of electrical contact strips of a type as defined above. In this document, the strip of lamellae is made of an electrically conductive or non-conductive material and the blades are coated in their central part with a layer of an electrically conductive material which envelops the two edges of each blade. We can therefore separate, thanks to this arrangement, the two necessary functions of elastic contact and good electrical conductivity. Indeed, the material of the strip which must ensure an elastic contact in the manner of a spring does not necessarily have good qualities of electrical conductivity. However, the strip of strips of the above document, each strip of which comprises a layer of electrically conductive material enveloping the two edges of the strip, is not easy to manufacture, each strip having to be individually coated with its conductive layer .
Le document US-A-4039238 qui est considéré comme représentant l'état de la technique le plus proche décrit, en relation avec la fig. 7, une bande de lamelles de contacts ayant une structure stratifiée comportant une couche en matériau bon conducteur et une couche d'un matériau ayant une élasticité élevée, cependant cette disposition n'assure un bon contact électrique que sur l'une des deux pièces du connecteur électrique.Document US-A-4039238 which is considered to represent the closest prior art described, in connection with FIG. 7, a strip of contact strips having a laminated structure comprising a layer of good conductive material and a layer of a material having a high elasticity, however this arrangement ensures good electrical contact only on one of the two parts of the electrical connector.
Le document mentionne également son procédé de fabrication.The document also mentions its manufacturing process.
La présente invention a pour but de proposer un procédé assurant une fabrication simple d'une bande de lamelles de contact électrique.The object of the present invention is to propose a method ensuring simple manufacture of a strip of electrical contact strips.
L'invention a ainsi pour objet un procédé de fabrication d'une bande de lamelles de contact électrique pour un connecteur électrique, lesdites lamelles étant réunies à leurs extrémités par deux bandes latérales continues, les lamelles étant sorties du plan desdites bandes latérales par torsion autour de leur axe longitudinal, perpendiculaire à la longueur de la bande, procédé selon lequel on part d'une bande d'un matériau déformable plastiquement et capable, après traitement, d'avoir des propriétés élastiques de ressort, en ce qu'au moins la partie centrale de la bande, sur une seule de ses deux faces, est revêtue d'une couche d'un matériau bon conducteur électrique, ladite bande étant ensuite encochée de façon à obtenir lesdites lamelles et bandes latérales continues, lesdites lamelles étant sorties du plan desdites bandes latérales par ladite torsion, en ce que l'un des bords de chaque lamelle est rabattu en ourlet dans le sens où le revêtement électriquement conducteur reste à l'extérieur, ladite bande étant ensuite soumise à un traitement de durcissement pour lui donner des propriétés élastiques de ressort.The subject of the invention is therefore a method of manufacturing a strip of electrical contact strips for an electrical connector, said strips being joined at their ends by two continuous lateral strips, the strips being pulled out of the plane of said lateral strips by twisting around their longitudinal axis, perpendicular to the length of the strip, method according to which starts from a strip of a plastically deformable material and capable, after treatment, of having elastic spring properties, in that at least the central part of the strip, on only one of its two faces, is coated with a layer of a material that is a good electrical conductor, said strip then being notched so as to obtain said strips and continuous side strips, said strips being taken out of the plane of said side strips by said twist, in that one of the edges of each strip is folded into a hem in the direction where the electrically conductive coating remains outside, said strip then being subjected to a hardening treatment to give it elastic spring properties.
L'invention a aussi pour objet une bande de lamelles de contact électrique pour un connecteur électrique, lesdites lamelles étant réunies à leurs extrémités par deux bandes latérales continues, les lamelles étant sorties du plan desdites bandes latérales par torsion autour de leur axe longitudinal, perpendiculaire à la longueur de la bande, ladite bande étant en un matériau ayant des propriétés élastiques de ressort, au moins la partie centrale de chaque lamelle étant revêtue sur une seule de ses faces d'un matériau électriquement bon conducteur, caractérisé en ce que l'un des bords de chaque lamelle est rabattu en ourlet dans un sens laissant apparaître le revêtement électriquement bon conducteur à l'extérieur.The invention also relates to a strip of electrical contact strips for an electrical connector, said strips being joined at their ends by two continuous lateral strips, the strips being taken out of the plane of said lateral strips by twisting around their longitudinal, perpendicular axis. the length of the strip, said strip being made of a material having elastic spring properties, at least the central part of each strip being coated on one of its faces with an electrically good conductive material, characterized in that the one of the edges of each strip is folded into a hem in a direction revealing the electrically conductive coating on the outside.
On va maintenant donner la description d'un exemple de mise en oeuvre de l'invention en se reportant au dessin annexé dans lequel :
- Les fig. 1 à 5 illustrent les étapes du procédé de fabrication d'une bande de lamelles de contact électrique selon l'invention, les fig. 4 et 5 montrant le résultat final.
- La fig. 6 montre schématiquement un connecteur électrique coaxial cylindrique dans lequel est utilisée une bande de lamelles de contact électrique selon l'invention.
- La fig. 6 montre très schématiquement un connecteur électrique coaxial cylindrique comportant une partie femelle 1 et une partie mâle 2 en matériaux électriquement conducteurs. Une bande intermédiaire 3 de lamelles de contact électrique est liée à la partie mâle 2. Cette bande intermédiaire qui doit assurer un bon contact électrique entre les pièces mâle 2 et femelle 1 a en outre pour fonction d'assurer un contact élastique entre les deux pièces.
- Figs. 1 to 5 illustrate the steps of the process for manufacturing a strip of electrical contact strips according to the invention, FIGS. 4 and 5 showing the final result.
- Fig. 6 schematically shows a cylindrical coaxial electrical connector in which a strip of electrical contact strips according to the invention is used.
- Fig. 6 very schematically shows a cylindrical coaxial electrical connector comprising a female part 1 and a male part 2 in electrically conductive materials. An intermediate strip 3 of electrical contact strips is linked to the male part 2. This intermediate strip which must ensure good electrical contact between the male 2 and female 1 parts also has the function of ensuring elastic contact between the two parts. .
Une telle bande 3 de lamelles de contact électrique peut également être utilisée dans un connecteur électrique plan où les deux pièces 1 et 2 sont alors planes et la bande 3 liée à l'une des deux.Such a strip 3 of electrical contact strips can also be used in a flat electrical connector where the two parts 1 and 2 are then flat and the strip 3 linked to one of the two.
En se reportant maintenant aux fig. 1 à 5, on va décrire le procédé de fabrication d'une telle bande 3 de lamelles de contact électrique.Referring now to Figs. 1 to 5, we will describe the process for manufacturing such a strip 3 of electrical contact strips.
On part, fig. 1, d'une bande 4 d'un matériau déformable plastiquement et capable, après traitement, d'avoir des propriétés élastiques de ressort. On utilise, par exemple, un alliage de béryllium-bronze. Ce matériau peut être adouci par un traitement thermique à 750°C suivi d'une trempe lui donnant une bonne malléabilité.We leave, fig. 1, a strip 4 of a plastically deformable material and capable, after treatment, of having elastic spring properties. For example, a beryllium-bronze alloy is used. This material can be softened by a heat treatment at 750 ° C followed by quenching giving it good malleability.
On part donc d'un tel matériau puis, comme montré sur la fig. 2, la partie centrale de la bande reçoit, sur l'une de ses faces seulement, une couche 5 d'un matériau bon conducteur électrique. Il s'agit par exemple d'un placage d'argent. Conformément à la fig. 3, la bande 4 est ensuite encochée de façon à la découper selon les contours souhaités, laissant apparaître des lamelles 6 reliées à leurs extrémités par deux bandes latérales continues 7 et 8, et comportant des languettes 9 utilisées pour la liaison de la bande avec l'une des parties du connecteur auquel elle est associée.We therefore start from such a material then, as shown in FIG. 2, the central part of the strip receives, on one of its faces only, a layer 5 of a material which is a good electrical conductor. This is for example a silver plating. In accordance with fig. 3, the strip 4 is then notched so as to cut it according to the desired contours, revealing strips 6 connected at their ends by two continuous lateral strips 7 and 8, and comprising tabs 9 used for the connection of the strip with the 'one of the parts of the connector with which it is associated.
Les lamelles 6 sont ensuite sorties du plan des bandes latérales 7 et 8 par torsion autour de leur axe longitudinal X perpendiculaire à la longueur L de la bande. Les bords 10 et 11 de chaque lamelle, comme on le voit fig. 5, sont également incurvés et surtout l'un des bords, le bord inférieur sur la fig. 5, est complètement rabattu en ourlet 12 comme le montre bien la fig. 5.The strips 6 are then taken out of the plane of the lateral strips 7 and 8 by twisting around their longitudinal axis X perpendicular to the length L of the strip. The edges 10 and 11 of each strip, as seen in fig. 5, are also curved and especially one of the edges, the lower edge in FIG. 5, is completely folded down at hem 12 as shown in FIG. 5.
Bien entendu, l'ourlet 12 est rabattu dans le sens où le placage électriquement bon conducteur 5 reste à l'extérieur de la pliure.Of course, the hem 12 is folded in the direction where the electrically good conductive plating 5 remains outside the fold.
Comme le montre également les fig. 4 et 5, et spécialement la fig. 5 qui montre la bande en coupe selon V-V de la fig. 4, les bandes latérales 7 et 8 sont plissées de façon à rapprocher les lamelles 6 les unes des autres et obtenir ainsi un plus grand nombre de lamelles par unité de longueur de bande.As also shown in figs. 4 and 5, and especially fig. 5 which shows the strip in section along VV of FIG. 4, the lateral strips 7 and 8 are pleated so as to bring the strips 6 closer to one another and thus obtain a greater number of strips per unit of strip length.
Lorsque la bande est ainsi placée entre les deux parties conjuguées d'un connecteur électrique, plan, ou cylindrique comme sur la fig. 6, les points de contact de chaque lamelle assurant le passage du courant d'une pièce à l'autre sont figurés en 13 et 14 sur l'une des lamelles 6, fig. 5. Ainsi, grâce à "l'ourlet" 12, il n'est pas nécessaire de réaliser un placage enveloppant les bords des lamelles 6 et la fabrication est facilitée puisqu'il suffit, par tout moyen connu, d'effectuer un placage, fig. 2, sur une seule des deux faces de la bande originale 4.When the strip is thus placed between the two conjugate parts of an electrical, flat, or cylindrical connector as in FIG. 6, the contact points of each strip ensuring the passage of current from one part to another are shown at 13 and 14 on one of the strips 6, fig. 5. Thus, thanks to the "hem" 12, it is not necessary to make a plating enveloping the edges of the lamellae 6 and the manufacture is facilitated since it suffices, by any known means, to carry out a plating, fig. 2, on only one of the two sides of the original tape 4.
L'encochage et les opérations de mise en forme : torsion, pliures, sont ensuite réalisés très facilement.Notching and shaping operations: twisting, bending, are then carried out very easily.
Une fois la confection de la bande terminée, il suffit de la soumettre à un traitement lui donnant des propriétés élastiques de ressort.Once the making of the strip is finished, it suffices to subject it to a treatment giving it elastic spring properties.
Dans le cas de l'exemple cité d'une bande en alliage de béryllium-bronze, on effectue un traitement de durcissement par traitement thermique à environ 325°C pendant à peu près trois heures.In the case of the example cited of a beryllium-bronze alloy strip, a hardening treatment is carried out by heat treatment at approximately 325 ° C. for approximately three hours.
Ainsi, l'invention permet de fabriquer d'une manière très simple une bande de lamelles de contact électrique dans laquelle on peut choisir un matériau pour ses qualités mécaniques et d'élasticité, indépendamment de ses qualités de conductivité électrique.Thus, the invention makes it possible to manufacture in a very simple manner a strip of electrical contact strips in which a material can be chosen for its mechanical and elastic qualities, independently of its qualities of electrical conductivity.
