Description

La présente invention est relative à un élément de contact mâle pour connecteur électrique à faible force d'insertion, du type comportant une partie de broche cylindrique se prolongeant à son extrémité par une partie fuselée terminée par un nez à génératrices à rayon constant.The present invention relates to a male contact element for an electrical connector with low insertion force, of the type comprising a cylindrical pin part extending at its end by a tapered part ending in a nose with generators of constant radius.

On utilise dans de nombreux domaines, et notamment dans le domaine aéronautique, des connecteurs multicontacts qui comportent un nombre de plus en plus élevé de contacts, certains connecteurs pouvant posséder plusieurs centaines de contacts.Multicontact connectors are used in many fields, and in particular in the aeronautical field, which include an increasing number of contacts, certain connectors being able to have several hundred contacts.

La force nécessaire pour accoupler un élément de connecteur mâle et un élément de connecteur femelle correspondant augmente en fonction du nombre de contacts par suite du cumul des forces d'insertion individuelles nécessaires pour engager chacun des éléments de contact mâles, en forme de broche, dans un élément de contact femelle correspondant en forme de douille élastique.The force required to couple a male connector element and a corresponding female connector element increases with the number of contacts as a result of the cumulative individual insertion forces required to engage each of the pin-shaped male contact elements in a corresponding female contact element in the form of an elastic socket.

Différentes formes pour de tels éléments de contact mâles ont été proposées dans le but de limiter la force d'insertion.Different forms for such male contact elements have been proposed in order to limit the insertion force.

Des exemples de réalisation peuvent en être trouvés dans les brevets français 78 01597 (FR-A 2 378 379) et 79 05208 (FR-A 2 450 510).Examples of embodiments can be found in French patents 78,01597 (FR-A 2,378,379) and 79 05208 (FR-A 2,450,510).

Dans le premier de ces documents la partie fuselée présente une forme définie par des surfaces de révolution générées autour de l'axe longitudinal du contact par des équations d'ellipse.In the first of these documents, the tapered part has a shape defined by surfaces of revolution generated around the longitudinal axis of the contact by ellipse equations.

Dans le second document cité, la partie fuselée est tronconique sur la majeure partie de sa longueur, les génératices rectilignes de la partie tronconique se raccordant à celles de la partie cylindrique par une portion circulaire.In the second document cited, the tapered part is frustoconical over most of its length, the rectilinear generatices of the frustoconical part connecting to those of the cylindrical part by a circular portion.

Les éléments de contact mâles selon ces documents antérieurs présentent tous, du fait de leurs caractéristiques de structure, une longueur de partie fuselée relativement importante par rapport au diamètre nominal de la partie cylindrique du contact, cette longueur étant dans tous les cas égale à au moins deux fois le diamètre de la partie cylindrique du contact.The male contact elements according to these prior documents all have, due to their structural characteristics, a relatively long tapered part length compared to the nominal diameter of the cylindrical part of the contact, this length being in all cases equal to at least twice the diameter of the cylindrical part of the contact.

Une telle longueur est incompatible avec certaines spécifications et normes telles que la norme DOD-C-83527.Such a length is incompatible with certain specifications and standards such as DOD-C-83527.

De plus, les éléments de contact mâles, selon les documents antérieurs mentionnés, présentent un nez de forme sensiblement hémisphérique, toutes les génératrices en arc de cercle définissant le nez ayant un centre commun sur l'axe longitudinal du contact.In addition, the male contact elements, according to the prior documents mentioned, have a nose of substantially hemispherical shape, all the generators in an arc defining the nose having a common center on the longitudinal axis of the contact.

L'expérience montre qu'une telle condition est particulièrement difficile à mettre en oeuvre dans le cadre des techniques d'usinage utilisées.Experience shows that such a condition is particularly difficult to implement in the context of the machining techniques used.

La présente invention se propose de réaliser un élément de contact, qui, tout en présentant une longueur en ce qui concerne sa partie fuselée qui est inférieure à celle des éléments de contact de l'art antérieur, soit facile à usiner et présente une force d'insertion du même ordre, voire inférieure.The present invention proposes to produce a contact element, which, while having a length as regards its tapered part which is less than that of the contact elements of the prior art, is easy to machine and has a force d 'insertion of the same order, even lower.

L'élément de contact selon l'invention se caractérise essentiellement par le fait que la partie fuselée présente une longueur L telle que 1,80d ≦ L ≦ 1,96d, d étant le diamètre nominal de la partie cylindrique de l'élément de contact mâle, et présente une première surface ogivale de révolution autour de l'axe longitudinal du contact, à génératrices à rayon constant, R, tel que 6,4d ≦ R ≦ à 7,9d, et une seconde surface ogivale de révolution autour de l'axe longitudinal du contact constituant le nez du contact, à génératrices à rayon constant, r, tel que 0,42d ≦ r ≦ à 0,52d, lesdites première et seconde surfaces ogivales se raccordant tangentiellement, et la première surface ogivale se raccordant tangentiellement à ladite partie cylindrique.The contact element according to the invention is essentially characterized by the fact that the tapered part has a length L such that 1.80d ≦ L ≦ 1.96d, d being the nominal diameter of the cylindrical part of the contact element male, and has a first ogival surface of revolution around the longitudinal axis of contact, with generators of constant radius, R, such as 6.4d ≦ R ≦ at 7.9d, and a second ogival surface of revolution around l longitudinal axis of the contact constituting the contact nose, with generators of constant radius, r, such as 0.42d ≦ r ≦ to 0.52d, said first and second ogival surfaces tangentially connecting, and the first ogival surface tangentially connecting to said cylindrical part.

Ainsi le contact selon l'invention est constitué dans sa partie terminale, en succession, d'une partie cylindrique et de deux parties ogivales de révolution ce qui permet un usinage simplifié, notamment au niveau du nez, dans la mesure où le centre de chaque génératrice en arc de cercle est décalé par rapport à l'axe longitudinal du contact.Thus the contact according to the invention consists in its terminal part, in succession, of a cylindrical part and two ogival parts of revolution which allows a simplified machining, in particular at the level of the nose, insofar as the center of each generator in an arc is offset from the longitudinal axis of the contact.

Avantageusement, la valeur de ce décalage e est comprise entre environ 0,08d et environ 0,17d.Advantageously, the value of this offset e is between approximately 0.08d and approximately 0.17d.

Le lieu géométrique des centres des génératrices en arc de cercle de la surface ogivale formant le nez est un cercle de rayon e disposé dans un plan orthogonal à l'axe longitudinal du contact.The geometrical place of the centers of the generatrices in an arc of a circle of the ogival surface forming the nose is a circle of radius e arranged in a plane orthogonal to the longitudinal axis of the contact.

De même, le lieu géométrique des centres des génératrices en arc de cercle de la surface ogivale prolongeant la partie cylindrique est un cercle de rayon R- d 2

Figure imgb0001
situé dans le plan frontal d'extrémité de la partie de broche cylindrique, orthogonal à l'axe longitudinal du contact.Likewise, the geometrical locus of the centers of the generatrices in an arc of a circle of the ogival surface extending the cylindrical part is a circle of radius R- d 2
Figure imgb0001
 located in the frontal end plane of the cylindrical pin part, orthogonal to the longitudinal axis of the contact.

De manière à faciliter l'usinage il est possible, selon une caractéristique particulière de l'invention, de réaliser l'extrémité de l'élément de contact sous la forme d'une surface plane orthogonale à l'axe longitudinal du contact, le diamètre ,p, de ladite surface étant tel que p ≦ 0,20d. La longueur du contact est alors diminuée d'une longueurΔ1 ≦ 0,06d. La présence de cette surface plane ne modifie pas le fonctionement du contact dans la mesure où le premier appui de la partie fuselée du contact dans la douille constituant l'élément de contact complémentaire s'effectue dans une zone située à une distance notablement supérieure à Δ1 de l'extrémité du contact.In order to facilitate machining, it is possible, according to a particular characteristic of the invention, to produce the end of the contact element in the form of a flat surface orthogonal to the longitudinal axis of the contact, the diameter , p, of said surface being such that p ≦ 0.20d. The length of the contact is then reduced by a length Δ1 ≦ 0.06d. The presence of this flat surface does not modify the functioning of the contact insofar as the first pressing of the tapered part of the contact in the socket constituting the complementary contact element takes place in an area located at a distance significantly greater than Δ1 from the end of the contact.

Un exemple de mise en oeuvre de l'invention est illustré dans le dessin annexé dans lequel la figure unique est une vue schématique de la partie d'extrémité d'un élément de contact mâle selon l'invention.An exemplary implementation of the invention is illustrated in the appended drawing in which the single figure is a schematic view of the end part of a male contact element according to the invention.

L'élément de contact selon l'invention comporte à l'extrémité de sa partie de broche cylindrique 1 une partie fuselée de longueur L constituée de deux surfaces ogivales de révolution autour de l'axe longitudinal du contact 2 et respectivement 3, la surface 3 définissant le nez du contact.The contact element according to the invention comprises at the end of its cylindrical pin part 1 a tapered part of length L consisting of two ogival surfaces of revolution around the longitudinal axis of the contact 2 and respectively 3, the surface 3 defining the nose of the contact.

Comme on le voit sur la figure, la surface ogivale 3 est définie par des génératrices en arc de cercle de rayon r, les génératrices illustrées étant centrées respectivement en A₁ et A₂, les points A₁ et A₂ étant disposés symétriquement par rapport à l'axe longitudinal du contact à une distance e de celui-ci.As can be seen in the figure, the ogival surface 3 is defined by generators in an arc of a radius r, the generators illustrated being centered respectively in A₁ and A₂, the points A₁ and A₂ being arranged symmetrically with respect to the axis longitudinal of the contact at a distance e from it.

La première surface ogivale 2 qui s'étend depuis le plan d'extrémité, passant par le point B, de la partie cylindrique 1 de diamètre d est définie par des génératrices de rayon R, le rayon R illustré sur le dessin étant centré en un point 0 situé dans le plan orthogonal à l'axe longitudinal du contact et passant par le point B. Bien entendu tous les centres des génératrices définissant la surface ogivale 2 sont centrés dans ce plan.The first ogival surface 2 which extends from the end plane, passing through point B, of the cylindrical part 1 of diameter d is defined by generators of radius R, the radius R illustrated in the drawing being centered at a point 0 located in the plane orthogonal to the longitudinal axis of the contact and passing through point B. Of course all the centers of the generators defining the ogival surface 2 are centered in this plane.

Comme on le voit sur le dessin, les génératrices de la surface ogivale 3 se terminent en C au niveau de l'axe longitudinal du contact conférant au nez une forme en obus. Ces génératrices se raccordent tangentiellement en T aux génératrices définissant la première surface ogivale 2 de rayon R.As can be seen in the drawing, the generatrices of the ogival surface 3 terminate in C at the level of the longitudinal axis of the contact giving the nose a shell shape. These generatrices are connected tangentially at T to the generatrices defining the first ogival surface 2 of radius R.

On a illustré en trait interrompu une surface plane 4 qui selon une variante de réalisation peut constituer l'extrémité du contact.Illustrated in broken lines is a flat surface 4 which, according to an alternative embodiment, can constitute the end of the contact.

Les éléments de contact mâles obtenus selon l'invention présentent, pour un même diamètre nominal d de la partie cylindrique, une longueur, en ce qui concerne la partie fuselée, inférieure en moyenne de 20% à la longueur moyenne des contacts réalisés selon les brevets mentionnés en préambule, la force d'insertion mesurée pour les mêmes douilles étant sensiblement du même ordre et même dans certains cas inférieure de l'ordre de 7%.The male contact elements obtained according to the invention have, for the same nominal diameter d of the cylindrical part, a length, as regards the tapered part, less on average by 20% than the average length of the contacts produced according to the patents mentioned in the preamble, the insertion force measured for the same sockets being substantially of the same order and even in certain cases lower by the order of 7%.

La présente invention peut être mise en oeuvre avec tous les matériaux connus et utilisés pour des connecteurs à contacts multiples actuels. De plus l'invention peut être mise en oeuvre avec toutes les techniques d'usinage appropriées permettant notamment d'obtenir les états de surface nécessaires à ce type d'application.The present invention can be implemented with all known materials used for current multiple contact connectors. In addition, the invention can be implemented with all the appropriate machining techniques, in particular making it possible to obtain the surface conditions necessary for this type of application.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter de nombreuses variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit.Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be brought to many variations and modifications without departing from its scope or nor of his mind.
