Abstract
Description
La présente invention concerne un contact électrique à organes de contact protégés et elle s'applique, plus particulièrement, aux contacts du genre de ceux comportant un corps tubulaire et,au moins, un organe de contact constitué par une languette obtenue par découpage,selon trois côtés, et pliage vers l'intérieur du corps. The present invention relates to an electrical contact with protected contact members and it applies, more particularly, to contacts of the kind of those comprising a tubular body and, at least, a contact member constituted by a tab obtained by cutting, according to three sides, and folding inward of the body.
Le mode de réalisation des organes de contact conduit à l'obtention, sur le corps, d'ouvertures situées au droit desdits organes. The embodiment of the contact members leads to obtaining, on the body, openings located at the level of said members.
L'expérience a montré que, durant les diverses manipulations auxquelles le contact est soumis préalablement à sa mise en place dans un boîtier isolant, des corps étrangers pouvaient pénétrer dans les ouvertures précitées et endommager les organes de contact. Un tel inconvénient résulte,notamment, du stockage, en vrac, des contacts. Dans ce cas, la queue de l'un des contacts peut pénétrer dans une ouverture d'un autre contact, s'y coincer, et endommager lors de son retrait l'organe de contact correspondant. Experience has shown that, during the various manipulations to which the contact is subjected prior to its installation in an insulating case, foreign bodies could penetrate the aforementioned openings and damage the contact members. Such a drawback results, in particular, from the storage, in bulk, of the contacts. In this case, the tail of one of the contacts can penetrate into an opening of another contact, get stuck there, and damage when it withdraws the corresponding contact member.
Par ailleurs, lors de l'introduction d'un élément mâle, tel qu'une broche, on peut aussi détériorer l'organe de contact,si ledit élément mâle n'est pas présenté dans l'axe du boîtier comportant les organes lamellaires. Furthermore, during the introduction of a male element, such as a pin, one can also damage the contact member, if said male element is not presented in the axis of the housing comprising the lamellar organs.
La présente invention,qui remédie à ces inconvénients,est remarquable en ce que l'ouverture créée par la réalisation de la languette formant l'organe de contact est obturée par une patte formant, initialement, un prolongement d'une extrémité du corps du contact, ladite patte étant rabattue vers l'extérieur pour être placée au-dessus de ladite ouverture. The present invention, which overcomes these drawbacks, is remarkable in that the opening created by the production of the tongue forming the contact member is closed by a tab forming, initially, an extension of one end of the body of the contact. , said tab being folded outwardly to be placed above said opening.
L'invention sera mieux comprise par la description qui va suivre, faite en se référant aux dessins annexés à titre d'exemple indicatif seulement,sur lesquels:
La figure 1 est une vue en perspective d'un contact conforme à l'invention
La figure 2 est une vue en coupe transversale montrant le contact de la figure 1 engagé dans un boîtier isolant usuel
La figure 3 est une vue analogue à celle 1, montrant la position des organes de contact lors de l'introduction d'une broche mâle:
Les figures 4 à 7 sont des vues en perspective illustrant un mode de réalisation du contact de la figure 1. The invention will be better understood from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is a perspective view of a contact according to the invention
Figure 2 is a cross-sectional view showing the contact of Figure 1 engaged in a conventional insulating housing
FIG. 3 is a view similar to that 1, showing the position of the contact members during the introduction of a male pin:
Figures 4 to 7 are perspective views illustrating an embodiment of the contact of Figure 1.
En se reportant à la figure 1, on voit que,de la façon connue,le contact 1 présente un corps 2,tubulaire,obtenu par découpage et pliage se prolongeant par une queue 3 à laquelle on raccorde le conducteur électrique. Referring to Figure 1, we see that, in known manner, the contact 1 has a body 2, tubular, obtained by cutting and folding extended by a tail 3 to which the electrical conductor is connected.
De la façon connue, le contact 1. qui comporte un corps 2 de section prismatique, présente sur chacune de deux de ses faces opposées, une ouverture 4,résultant d'un découpage judicieux, permettant de réaliser une languette Squi, après pliage et cambrage, constitue l'un des organes de contact. In known manner, the contact 1. which comprises a body 2 of prismatic section, present on each of two of its opposite faces, an opening 4, resulting from a judicious cutting, making it possible to produce a Squi tongue, after folding and bending , constitutes one of the contact bodies.
Selon l'invention, une patte 6 s'étend -au-dessus de l'ouverture 4 et recouvre partiellement l'organe de contact 5. According to the invention, a tab 6 extends above the opening 4 and partially covers the contact member 5.
De cette façon, on évite que des corps étrangers pénètrent dans l'ouverture 4 et endommagent l'organe 5. In this way, we prevent foreign bodies from entering the opening 4 and damaging the member 5.
Les pattes 6 sont réalisées dans le même matériau que les organes 5 et sont, de ce fait, élastiquement déformables. The legs 6 are made of the same material as the members 5 and are, therefore, elastically deformable.
Comme cela ressort tout particulièrement de la figure 3, lorsqu'un organe mâle, tel que la broche B, est engagé dans le corps 2,les organes de contact 5 fléchissent vers l'extérieur et rencontrent les pattes 6 qui coopérent élastiquement avec lesdits organes 5, en améliorant la pression de contact. As is particularly apparent from FIG. 3, when a male member, such as the pin B, is engaged in the body 2, the contact members 5 bend outward and meet the tabs 6 which cooperate elastically with said members 5, by improving the contact pressure.
De la façon connue, le contact 1 est maintenu dans le boîtier isolant usuel 7 par l'entremise d'un bras élastiquement déformable 8 comportant une dent 9 susceptible de pénétrer élastiquement dans une ouverture du corps 2 du contact. In known manner, the contact 1 is maintained in the usual insulating housing 7 by means of an elastically deformable arm 8 comprising a tooth 9 capable of elastically penetrating an opening in the body 2 of the contact.
Selon une autre caractéristique de l'invention, l'une au moins des pattes 6 présente une ouverture 10 dans laquelle peut pénétrer la dent 9 du bras 8. According to another characteristic of the invention, at least one of the legs 6 has an opening 10 into which the tooth 9 of the arm 8 can penetrate.
De cette façon, la patte 6 coopère efficacement au maintien du contact dans son boîtier. In this way, the tab 6 cooperates effectively in maintaining contact in its housing.
Le contact de la figure 1 peut être obtenu par découpage et pliage, comme montré en regard des figures 4 à 7. The contact of FIG. 1 can be obtained by cutting and folding, as shown opposite FIGS. 4 to 7.
La première phase de réalisation du contact consiste à découper un flan tel que celui montré sur la figure 4 qui,selon l'invention,présente des pattes 5a et 5b, latérales, et sur son bord antérieur ll,une patte médiane 6a et des pattes latérales 6b. The first phase of making the contact consists in cutting a blank such as that shown in FIG. 4 which, according to the invention, has lateral tabs 5a and 5b, and on its front edge ll, a central tab 6a and tabs lateral 6b.
La patte 6a présente une ouverture 12, analogue à celle 10 décrite en regard de la figure 1, tandis que celles 6b présentent des encoches 12b qui coopèreront pour former, après pliage,une ouverture analogue à celle 12. The tab 6a has an opening 12, similar to that 10 described with reference to FIG. 1, while those 6b have notches 12b which will cooperate to form, after folding, an opening similar to that 12.
Dans un premier temps,on plie et on cambre les pattes 5a et 5b pour obtenir la configuration montrée sur la figure 5,la patte Sa devenant un organe de contact et celles 5b coopérant ultérieurement pour former un autre contact. Firstly, the legs 5a and 5b are folded and arched to obtain the configuration shown in FIG. 5, the tab Sa becoming a contact member and those 5b subsequently cooperating to form another contact.
Dans un second temps, on replie les pattes 6a et 6b qui, comme montré sur la figure 6, sont placées sous celles 5a et 5b. In a second step, the legs 6a and 6b are folded back, which, as shown in FIG. 6, are placed under those 5a and 5b.
Dans un troisième temps, on relève à angle droit les bords de l'ébauche de la figure 6 pour obtenir la configuration montrée sur la figure 7 puis, finalement, on replie à nouveau vers le centre l'ébauche de la figure 7 pour achever la formation du corps tubulaire 2. In a third step, the edges of the blank of FIG. 6 are raised at right angles to obtain the configuration shown in FIG. 7, then, finally, the blank of FIG. 7 is again folded towards the center to complete the formation of the tubular body 2.
Pour faciliter la compréhension, on a fait figurer en traits mixtes sur les dessins, les lignes selon lesquelles s'effectuent les pliages. To facilitate understanding, the lines along which the folds are made have been shown in phantom in the drawings.
Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
