Description

La présente invention concerne un organe de contact électrique femelle.The present invention relates to a female electrical contact member.

L'invention vise un organe de contact électrique femelle selon la première partie de la revendication 1.
Un tel élément est connu par FR-A-2 360 188.The invention relates to a female electrical contact member according to the first part of claim 1.
Such an element is known from FR-A-2 360 188.

La technique antérieure connaît un grand nombre d'organes de contacts électriques femelles du type ci-dessus. Généralement, afin d'assurer une bonne liaison électrique avec l'organe mâle celui-ci doit être pincé avec une certaine pression de sorte que l'engagement de l'organe mâle nécessite une certaine force; une telle disposition ne se prête pas bien à une mécanisation de l'assemblage des deux organes de contact.The prior art knows a large number of female electrical contact members of the above type. Generally, in order to ensure a good electrical connection with the male organ, this must be pinched with a certain pressure so that the engagement of the male organ requires a certain force; such an arrangement does not lend itself well to mechanization of the assembly of the two contact members.

L'un des buts de l'invention est de remédier à cet inconvénient.One of the aims of the invention is to remedy this drawback.

L'organe de contact femelle, selon l'invention, est du type réalisé à partir d'un flan métallique présentant une certaine élasticité, ledit flan étant découpé et plié afin de présenter, à une extrémité, des moyens pour sa liaison à un circuit électrique, tandis qu'à l'autre extrémité il est conformé pour présenter un conduit à section rectangulaire destiné à recevoir un organe de contact électrique mâle, deux parois opposées du conduit étant prolongées pour former des lames élastiques qui sont pliées à l'intérieur dudit conduit afin de former une pince élastique pour enserrer ledit organe mâle et est caractérisé en ce que chaque lame élastique comporte sur sa face tournée en regard de l'autre lame élastique, au moins, deux saillies, chaque saillie de l'une des lames étant disposée pour coïncider avec la saillie correspondante de l'autre lame, lesdites saillies affectant la forme d'une pyramide. Ainsi, on réduit l'effort nécessaire à l'insertion de l'organe mâle dans le conduit de l'organe femelle tout en réalisant une bonne liaison électrique.The female contact member according to the invention is of the type produced from a metal blank having a certain elasticity, said blank being cut and folded so as to present, at one end, means for its connection to a circuit electric, while at the other end it is shaped to present a rectangular section conduit intended to receive a male electrical contact member, two opposite walls of the conduit being extended to form elastic blades which are bent inside said conduit in order to form an elastic clamp for clamping said male member and is characterized in that each elastic blade has on its face turned opposite the other elastic blade, at least two projections, each projection of one of the blades being arranged to coincide with the corresponding projection of the other blade, said projections taking the shape of a pyramid. This reduces the effort required to insert the male organ into the conduit of the female organ while achieving a good electrical connection.

Enfin, chaque lame élastique comporte, au voisinage de son extrémité libre, deux oreilles pliées pour s'étendre perpendiculairement auxdites lames et, du côté des parois latérales, que lesdites lames prolongent. On limite ainsi le débattement des lames élastiques et on évite qu'elles puissent être forcées.Finally, each elastic blade has, near its free end, two ears folded to extend perpendicular to said blades and, on the side of the side walls, that said blades extend. This limits the travel of the elastic blades and prevents them from being forced.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en plan montrant un flan dans lequel a été découpé un organe de contact femelle perfectionné, selon l'invention.Figure 1 is a plan view showing a blank from which has been cut an improved female contact member according to the invention.

Figure 2 est une vue en perspective montrant la réalisation de l'organe de contact de la figure 1.Figure 2 is a perspective view showing the embodiment of the contact member of Figure 1.

Figure 3 est une vue en perspective de l'une des lames élastiques.Figure 3 is a perspective view of one of the elastic blades.

Figure 4 est une vue en coupe suivant la ligne 4-4 de la figure 3.Figure 4 is a sectional view along line 4-4 of Figure 3.

Figure 5 est une vue en coupe montrant l'engagement d'un organe de contact mâle.Figure 5 is a sectional view showing the engagement of a male contact member.

Aux figures 1 à 5, on a représenté un organe de contact électrique femelle qui est formé à partir d'un flan métallique bon conducteur de l'électricité et qui est découpé pour présenter un corps 1 avec, à une extrémité, deux pattes 2 destinées à être serties sur un conducteur et deux pattes 3 destinées à être serties sur l'extrémité dénudée dudit conducteur.Figures 1 to 5, there is shown a female electrical contact member which is formed from a metal blank good conductor of electricity and which is cut to present a body 1 with, at one end, two tabs 2 intended to be crimped onto a conductor and two tabs 3 intended to be crimped onto the stripped end of said conductor.

Du côté opposé aux pattes 2, le corps 1 est prolongé par une partie 5 destinée à former un conduit de section rectangulaire.On the side opposite the legs 2, the body 1 is extended by a part 5 intended to form a duct of rectangular section.

La partie 5 comprend une partie 6 destinée à former l'âme, deux bandes latérales 7 et 8 destinées, après pliage à angle droit, à former les parois latérales du conduit et une bande 9 adjacente à la bande 8 et destinée à être pliée pour former la paroi de plafond du conduit, cette partie étant fixée par son bord libre au bord libre de la paroi latérale 7.Part 5 comprises a part 6 intended to form the core, two lateral strips 7 and 8 intended, after bending at right angles, to form the lateral walls of the duct and a strip 9 adjacent to the strip 8 and intended to be folded for forming the ceiling wall of the duct, this part being fixed by its free edge to the free edge of the side wall 7.

La paroi latérale 7 est prolongée par une lame élastique 10 qui présente, au voisinage de son extrémité libre, deux oreilles 11.The side wall 7 is extended by an elastic blade 10 which has, near its free end, two ears 11.

La paroi latérale 8 est prolongée par une lame élastique 12 pourvue, au voisinage de son extrémité libre, de deux oreilles 13.The side wall 8 is extended by an elastic blade 12 provided, in the vicinity of its free end, with two ears 13.

Comme on le voit à la figure 2, les lames élastiques 10 et 12 sont pliées vers l'intérieur du conduit de manière à constituer des pinces pour enserrer élastiquement un organe mâle de contact électrique 15. Les oreilles 11 et 13 sont pliées, à angle droit, pour constituer des butées susceptibles de porter contre les parois latérales correspondantes afin d'éviter que les lames élastiques puissent être forcées et qu'ainsi lesdites lames n'enserrent plus suffisamment l'organe 15.As can be seen in FIG. 2, the elastic blades 10 and 12 are bent towards the inside of the conduit so as to constitute pliers for elastically enclosing a male electrical contact member 15. The ears 11 and 13 are bent, at an angle straight, to constitute stops capable of bearing against the corresponding side walls in order to avoid that the elastic blades can be forced and that thus said blades no longer sufficiently enclose the member 15.

Comme cela est représenté aux figures 3, 4 et 5, la lame élastique 10 comporte, sur sa face tournée du côté de la face correspondante de la lame élastique 12, un embouti déterminant deux pyramides 14 dont les sommets sont situés dans un plan perpendiculaire à l'axe longitudinal de la lame.As shown in FIGS. 3, 4 and 5, the elastic blade 10 comprises, on its face turned towards the side of the corresponding face of the elastic blade 12, a stamped element determining two pyramids 14 whose vertices are located in a plane perpendicular to the longitudinal axis of the blade.

La lame élastique 12 présente également un embouti sur sa face tournée en regard de la lame 10 pour former deux pyramides 14, les sommets de celle-ci coïncidant avec les sommets des pyramides de la lame 10.The elastic blade 12 also has a stamped on its face turned opposite the blade 10 to form two pyramids 14, the vertices of the latter coinciding with the vertices of the pyramids of the blade 10.

Ainsi, lorsque l'organe 15 est inséré entre les lames 10 et 12, il est enserré entre quatre points de contact ce qui favorise une bonne liaison électrique, l'effort d'insertion de l'organe 15 étant néanmoins diminué.Thus, when the member 15 is inserted between the blades 10 and 12, it is sandwiched between four contact points which promotes good electrical connection, the effort of inserting the member 15 being nevertheless reduced.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre des revendications. On a représenté aux figures des pattes de sertissage 2 et 3, mais bien entendu, ces moyens de liaison électriques peuvent être remplacés par d'autres.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the claims. The figures show crimping lugs 2 and 3, but of course, these electrical connection means can be replaced by others.
