Abstract

The present invention concerns a spindle-receiving jack for forming an elecrtrical connection, the said jack comprising at least three resilient tongues defining an opening for forcibly passing the stem of the spindle and shaped in such a manner that each of them has its own resonance frequency.

Description

La présente invention concerne une douille de réception d'une broche pour réaliser une connexion électrique ainsi qu'un connecteur électrique comportant au moins une telle douille.The present invention relates to a socket for receiving a pin for making an electrical connection as well as an electrical connector comprising at least one such socket.

La présente invention trouve application dans les dispositifs de connexion de câbles électriques destinés à véhiculer des signaux rapides d'information comme c'est le cas par exemple pour les appareils de commande et de contrôle utilisés dans les avions.The present invention finds application in electrical cable connection devices intended to convey fast information signals as is the case for example for command and control devices used in aircraft.

On connaît une douille de réception d'une broche du type comprenant deux ou plusieurs lames élastiques identiques définissant l'ouverture cylindrique de passage en force de la tige de la broche.There is known a socket for receiving a spindle of the type comprising two or more identical elastic blades defining the cylindrical opening for passage of force of the spindle rod.

Cependant, une telle connexion électrique est sujette à des micro-coupures du signal électrique d'information lors de l'existence de vibrations externes d'une fréquence correspondant à la fréquence de résonance des lames élastiques.However, such an electrical connection is subject to micro-cuts in the electrical information signal during the existence of external vibrations of a frequency corresponding to the resonance frequency of the elastic plates.

La présente invention a pour but d'éliminer l'inconvénient ci-dessus en proposant une douille de réception qui, une fois connectée à une broche correspondante, assure une connexion électrique extrêmement fiable et donc non sujette à des micro-coupures.The object of the present invention is to eliminate the above drawback by proposing a reception socket which, once connected to a corresponding pin, provides an extremely reliable electrical connection and therefore not subject to micro-cuts.

Pour cela, la douille selon la présente invention est caractérisée en ce qu'elle comprend au moins trois lames élastiques définissant une ouverture du passage en force de la tige de la broche et conformées de façon à avoir chacune une fréquence propre de résonance.For this, the socket according to the present invention is characterized in that it comprises at least three elastic blades defining an opening of the passage in force of the spindle rod and shaped so as to each have a natural frequency of resonance.

Selon une caractéristique de l'invention, les lames élastiques précitées sont disposées autour de l'axe de la douille de façon à définir respectivement des arcs de cercle de longueurs différentes.According to a characteristic of the invention, the above-mentioned elastic blades are arranged around the axis of the sleeve so as to respectively define arcs of a circle of different lengths.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :

  • La figure 1 est une vue en perspective des éléments constitutifs séparés les uns des autres d'une connexion électrique conforme à l'invention ; et
  • La figure 2 est une vue en coupe selon la ligne II-II de la figure 1.
The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating a mode of the invention and in which:
  • Figure 1 is a perspective view of the component parts separated from each other of an electrical connection according to the invention; and
  • Figure 2 is a sectional view along line II-II of Figure 1.

En se référant aux figures, la référence 1 désigne une broche métallique d'une connexion électrique destinée à s'engager dans une douille 2 métallique.Referring to the figures, the reference 1 designates a metal pin of an electrical connection intended to engage in a metal socket 2.

La broche 1 comporte une partie tubulaire 3 dans laquelle est fixée l'extrémité dénudée d'un fil électrique (non représenté) et une tige 4 prolongeant la partie tubulaire 3. L'extrémité dénudée du fil électrique est fixée dans la partie tubulaire 3 par exemple par soudage ou par sertissage de la partie tubulaire. La broche 1 comporte également une collerette 5 au voisinage de sa partie médiane de jonction entre la partie tubulaire 3 et la tige 4.The pin 1 comprises a tubular part 3 in which is fixed the stripped end of an electric wire (not shown) and a rod 4 extending the tubular part 3. The stripped end of the electric wire is fixed in the tubular part 3 by example by welding or crimping the tubular part. Pin 1 also has a flange 5 in the vicinity of its median junction part between the tubular part 3 and the rod 4.

La douille 2 comprend également une partie tubulaire 6 de réception de l'extrémité dénudée d'un fil électrique (non représenté) et prolongée par une partie cylindrique pleine 7, dont l'extrémité est solidaire de trois lames élastiques 8a-8c de même longueur et définissant une ouverture approximativement cylindrique 9 pour le passage en force de la tige 4 de broche, laquelle ouverture est coaxiale à l'axe longitudinal de la douille 2. La douille 2 comprend de plus un épaulement 10 à l'endroit de jonction entre les lames élastiques 8a-8c et la partie cylindrique 7.The sleeve 2 also comprises a tubular part 6 for receiving the stripped end of an electric wire (not shown) and extended by a solid cylindrical part 7, the end of which is integral with three elastic blades 8a-8c of the same length and defining an approximately cylindrical opening 9 for the forced passage of the spindle rod 4, which opening is coaxial with the longitudinal axis of the socket 2. The socket 2 further comprises a shoulder 10 at the junction between the elastic blades 8a-8c and the cylindrical part 7.

Les lames élastiques 8a-8c sont disposées autour de l'axe de la douille 2 de façon à définir respectivement des arcs de cercle de longueurs différentes. Dans le cas présent, les angles interceptant les trois arcs de cercle des lames élastiques 8a-8c ont respectivement des valeurs d'environ 90°, 120° et 150°.The elastic blades 8a-8c are arranged around the axis of the sleeve 2 so as to define circular arcs of different lengths, respectively. In the present case, the angles intercepting the three arcs of a circle of the elastic blades 8a-8c have values of approximately 90 °, 120 ° and 150 ° respectively.

Dans la mesure où les lames élastiques 8a-8c ont des configurations géométriques différentes, chacune a sa propre valeur de fréquence de résonance. Ainsi lorsqu'une connexion électrique est réalisée entre la broche 1 et la douille 2 et que celle-ci est soumise à une vibration d'une fréquence correspondant à la fréquence de résonance de l'une des trois lames élastiques, les deux autres lames élastiques maintiendront le contact électrique avec la tige 4 de la broche 1 puisqu'elles ont chacune une fréquence de résonance différente de la fréquence de la vibration.Since the elastic strips 8a-8c have different geometric configurations, each has its own resonant frequency value. Thus when an electrical connection is made between the pin 1 and the socket 2 and the latter is subjected to a vibration of a frequency corresponding to the resonant frequency of one of the three elastic blades, the other two elastic blades will maintain electrical contact with the rod 4 of the pin 1 since they each have a resonant frequency different from the frequency of the vibration.

La douille 1 a été décrite comme comportant trois lames métalliques élastiques, mais il est bien évident que celle-ci peut être conformée de façon à comporter quatre, cinq, ou plus de lames élastiques réparties autour de l'axe de la broche de façon à définir respectivement des arcs de cercle de longueurs différentes ou des arcs de cercle inscrits respectivement dans des angles au centre de valeurs différentes.Socket 1 has been described as having three blades elastic metal, but it is obvious that it can be shaped so as to include four, five, or more elastic blades distributed around the axis of the spindle so as to respectively define arcs of circle of different lengths or arcs of circles inscribed respectively in angles at the center of different values.

La figure 1 représente un manchon de protection 11 qui, une fois la connexion électrique assemblée, entoure coaxialement les lames 8a-8c et est en appui par ses deux extrémités entre la collerette 5 de la broche 1 et l'épaulement 10 de la douille 2.Figure 1 shows a protective sleeve 11 which, once the electrical connection assembled, coaxially surrounds the blades 8a-8c and is supported by its two ends between the flange 5 of the spindle 1 and the shoulder 10 of the socket 2 .

L'invention s'applique notamment aux connecteurs électriques dont la partie mâle comporte une pluralité de broches 1 et la partie femelle une pluralité de douilles 2 conformes à l'invention.The invention applies in particular to electrical connectors, the male part of which comprises a plurality of pins 1 and the female part of which a plurality of sockets 2 in accordance with the invention.
