Description

La présente invention vise un organe de connexion électrique du type comportant une partie mâle ou femelle destinée à coopérer avec une partie mâle ou femelle correspondante et dont une extrémité est pourvue d'un organe de raccordement à un conducteur électrique.The present invention relates to an electrical connection member of the type comprising a male or female part intended to cooperate with a corresponding male or female part and one end of which is provided with a member for connection to an electrical conductor.

L'invention vise également des organes de connexion dits hermaphrodite, dans lesquels il est prévu une partie qui coopère avec une partie identique d'un autre connecteur celui-ci étant tourné recto-verso.The invention also relates to so-called hermaphrodite connection members, in which a part is provided which cooperates with an identical part of another connector, the latter being turned recto-verso.

L'organe de raccordement électrique est généralement constitué par deux paires de pattes, une paire étant destinée à enserrer une partie dénudée du conducteur électrique et la seconde à enserrer ledit conducteur et sa gaine. On est donc obligé de procéder à une première opération de dénudage du conducteur, puis à une seconde opération de mise en place du conducteur et enfin une opération de sertissage au cours de laquelle les pattes sont rabattues sur le conducteur. Ces opérations étant complexes, on a imaginé de réaliser des organes de raccordement qui assurent, d'une part, le dénudage du conducteur et, d'autre part la fixation de ce dernier, de tels organes de raccordement étant connus sous l'appellation de "raccordement à déplacement d'isolant".The electrical connection member generally consists of two pairs of lugs, one pair being intended to enclose a stripped portion of the electrical conductor and the second to enclose said conductor and its sheath. It is therefore necessary to carry out a first stripping operation of the conductor, then a second operation of placing the conductor and finally a crimping operation during which the tabs are folded over the conductor. These operations being complex, it has been imagined to produce connection members which ensure, on the one hand, the stripping of the conductor and, on the other hand the fixing of the latter, such connection members being known by the name of "insulation displacement connection".

L'invention vise un raccordement à déplacement d'isolant.The invention relates to an insulation displacement connection.

Les raccordements de ce type comprennent généralement une patte avec une fente dans laquelle on introduit le conducteur, la largeur de la fente étant telle que l'isolant est cisaillé et qu'ainsi les torons dudit conducteur en coopérant avec les bords de la fente assurent la liaison électrique. Ce type de raccordement est par exemple décrit dans un article de T. YOSHIZAKI publié dans "Journal of Electronic Engineering" n° 242 (1987.02) p. 50-53Connections of this type generally include a tab with a slot into which the conductor is introduced, the width of the slot being such that the insulator is sheared and thus the strands of said conductor, cooperating with the edges of the slot, ensure the electrical connection. This type of connection is for example described in an article by T. YOSHIZAKI published in "Journal of Electronic Engineering" No. 242 (1987.02) p. 50-53

Une telle disposition ne s'est pas toujours révélée très efficace et l'un des buts de la présente invention est de réaliser un raccordement à déplacement d'isolant offrant une grande sécurité pour le raccordement du conducteur, la liaison électrique et la fixation dudit conducteur.Such an arrangement has not always been found to be very effective and one of the aims of the present invention is to provide an insulation displacement connection offering great security for the connection of the conductor, the electrical connection and the fixing of said conductor.

L'organe de connexion électrique, selon l'invention est du type réalisé à partir d'une bande métallique bonne conductrice de l'électricité découpée et convenablement pliée, à partir d'une semelle, d'une part, pour présenter un organe de contact électrique mâle, femelle ou hermaphrodite et, d'autre part, un organe de raccordement électrique avec un conducteur et du type à déplacement d'isolant dans lequel la semelle comporte latéralement d'un côté une première patte et de l'autre côté une seconde patte, les deux pattes étant destinées à s'étendre perpendiculairement à la semelle, la première patte du côté tourné vers l'organe de connexion étant pourvue d'un prolongement destiné à être plié pour s'étendre, d'une part, perpendiculairement la semelle et d'autre part, perpendiculairement à la patte, ledit prolongement comportant une fente ouverte et évasée du côté de son extrémité libre, opposée à celle adjacente à la semelle, tandis que la seconde patte du côté tourné l'opposé de l'organe de connexion est pourvue d'un prolongement destiné à être plié pour s'étendre perpendiculairement à la semelle, d'une part, et perpendiculairement à la seconde patte d'autre part, ledit prolongement comportant une fente ouverte et évasée du côté de son extrémité libre opposée à celle adjacente à la semelle, un tel organe de connexion est connu de US-A-4575173. L'organe de connexion de la présente invention se distingue de cet état de la technique en ce que le bord libre latéral du prolongement de la première patte est pourvu d'une barrette destinée à s'insérer dans un décrochement du bord correspondant de la seconde patte, ce dernier étant prolongé par une languette de verrouillage rabattue contre le prolongement de la première patte, le bord libre latéral du prolongement de la seconde patte comportant une barrette destinée à s'insérer dans un décrochement du bord correspondant de la première patte, ce dernier étant prolongé par une languette de verrouillage rabattue contre le prolongement de la seconde patte.The electrical connection member according to the invention is of the type produced from a metal strip which is a good conductor of electricity, cut and suitably folded, from a sole, on the one hand, to present a male, female or hermaphrodite electrical contact and, on the other hand, an electrical connection member with a conductor and of the insulating displacement type in which the sole has laterally on one side a first tab and on the other side a second tab, the two tabs being intended to extend perpendicular to the sole, the first tab on the side facing the connection member being provided with an extension intended to be folded to extend, on the one hand, perpendicularly the sole and on the other hand, perpendicular to the tab, said extension comprising an open and flared slot on the side of its free end, opposite to that adjacent to the sole, while the side flap on the opposite side of the connection member is provided with an extension intended to be folded to extend perpendicular to the sole, on the one hand, and perpendicular to the second tab on the other hand, said extension comprising an open and flared slot on the side of its free end opposite to that adjacent to the sole, such a connection member is known from US-A-4575173. The connection member of the present invention differs from this state of the art in that the free lateral edge of the extension of the first tab is provided with a bar intended to be inserted in a recess of the corresponding edge of the second tab, the latter being extended by a locking tab folded against the extension of the first tab, the free lateral edge of the extension of the second tab having a bar intended to be inserted in a recess of the corresponding edge of the first tab, this the latter being extended by a locking tab folded against the extension of the second tab.

Suivant une caractéristique de détail, l'une des fentes de l'un des deux prolongements est plus large que celle de l'autre prolongement. Ainsi on obtient une meilleure tenue du conducteur et on évite que les lèvres des fentes des prolongements s'écartent trop ce qui risquerait de nuire à la liaison électrique de ladite fixation du conducteur.According to a characteristic of detail, one of the slots of one of the two extensions is wider than that of the other extension. Thus, the conductor is held better and the lips of the slots of the extensions are avoided to deviate too far, which could harm the electrical connection of said conductor attachment.

De préférence, la fente la plus large est la fente de celle du prolongement de la seconde patte.Preferably, the widest slit is the slit of that of the extension of the second tab.

Afin d'éviter une contrainte permanente sur le conducteur lorsqu'il est mis en place le fond des fentes se termine par un épanouissement.In order to avoid permanent stress on the conductor when it is in place, the bottom of the slots ends in a blooming.

Enfin, suivant une dernière caractéristique, les languettes des prolongements de la première et de la seconde patte sont prolongées de manière a être rabattues contre la face extérieure des pattes correspondantes.Finally, according to a last characteristic, the tongues of the extensions of the first and of the second tab are extended so as to be folded against the outer face of the corresponding tabs.

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

Figure 1 est une vue en plan d'un flan de tôle découpé pour obtenir un élément de contact, selon l'invention.Figure 1 is a plan view of a sheet blank cut to obtain a contact element according to the invention.

Figure 2 et figure 3 sont des vues en perspective montrant le pliage de la partie de raccordement avec le fil conducteur.Figure 2 and Figure 3 are perspective views showing the folding of the connection part with the conductive wire.

Figure 4 montre en perspective une languette mâle.Figure 4 shows in perspective a male tab.

Figure 5 montre en perspective un élément de contact femelle.Figure 5 shows in perspective a female contact element.

Figure 6 est une vue en perspective d'une variante de réalisation de l'invention.Figure 6 is a perspective view of an alternative embodiment of the invention.

Aux différentes figures, on a représenté un organe de contact électrique destiné à être placé dans un canal correspondant d'un boîtier isolant. Ce contact électrique peut être mâle, femelle ou hermaphrodite.The various figures show an electrical contact member intended to be placed in a corresponding channel of an insulating housing. This electrical contact can be male, female or hermaphrodite.

L'organe de contact électrique est réalisé à partir d'une bande de métal bonne conductrice de l'électricité et ayant une certaine élasticité.The electrical contact member is made from a metal strip that is good conductor of electricity and has a certain elasticity.

La bande est découpée pour présenter une partie A destinée à être conformée pour constituer un organe de contact mâle, femelle ou hermaphrodite et une partie B constituant la partie de raccordement avec un conducteur électrique, cette partie B formant un organe de raccordement à déplacement d'isolant.The strip is cut to present a part A intended to be shaped to constitute a male, female or hermaphrodite contact member and part B constituting the connection part with an electrical conductor, this part B forming a connection member with displacement of insulating.

La partie A pouvant être d'un type connu ne sera pas décrite ici en détail. La partie B de raccordement avec le fil conducteur est découpée pour présenter une semelle 1 dont le prolongement sera conformé pour constituer l'organe de contact mâle, femelle ou hermaphrodite. Latéralement, d'un côté la semelle 1 comporte une première patte 2 qui est destinée à être pliée le long d'une ligne 3 pour s'étendre perpendiculairement à la semelle 1.Part A, which may be of a known type, will not be described here in detail. Part B for connection with the conductive wire is cut to present a sole 1, the extension of which will be shaped to constitute the male, female or hermaphrodite contact member. Laterally, on one side, the sole 1 has a first tab 2 which is intended to be folded along a line 3 to extend perpendicular to the sole 1.

La première patte 2 comporte un prolongement 4 destiné à être plié le long d'une ligne 8 pour s'étendre perpendiculairement, d'une part, à la patte 2 et, d'autre part, à la semelle 1. Le prolongement 4 comporte une fente 5 qui présente une partie 5a dont les lèvres sont parallèles et une partie 5b évasée vers un bord libre 6 dudit prolongement 4.The first tab 2 has an extension 4 intended to be folded along a line 8 to extend perpendicular, on the one hand, to the tab 2 and, on the other hand, to the sole 1. The extension 4 comprises a slot 5 which has a part 5a whose lips are parallel and a part 5b flared towards a free edge 6 of said extension 4.

Le prolongement 4 au voisinage du bord libre 6 et sur un bord libre 20 comporte une barrette 7.The extension 4 in the vicinity of the free edge 6 and on a free edge 20 comprises a bar 7.

La patte 2, le long de son bord opposé à la ligne 8 est prolongée par une languette de verrouillage 9 destinée à être pliée le long d'une ligne 27.The tab 2, along its edge opposite the line 8 is extended by a locking tab 9 intended to be folded along a line 27.

La semelle 1, du côté opposé à la patte 2, comporte une seconde patte 10 qui d'un côté comporte une languette de verrouillage 13 et du côte opposé un prolongement 17.The sole 1, on the side opposite to the tab 2, has a second tab 10 which on one side has a locking tab 13 and on the opposite side an extension 17.

La seconde patte 10 est destinée à être pliée le long d'une ligne 18 pour s'étendre perpendiculairement à la semelle 1, le prolongement 17 étant plié le long d'une ligne 11 pour s'étendre, d'une part, perpendiculairement la semelle 1 et, d'autre part, perpendiculairement à la patte 10.The second tab 10 is intended to be folded along a line 18 to extend perpendicular to the sole 1, the extension 17 being folded along a line 11 to extend, on the one hand, perpendicularly to the sole 1 and, on the other hand, perpendicular to tab 10.

Le prolongement 17 comporte une fente 14 qui présente une partie 14a dont les lèvres sont parallèles et une partie 14b évasée s'ouvrant sur un bord 26.The extension 17 comprises a slot 14 which has a part 14a whose lips are parallel and a flared part 14b opening on an edge 26.

La languette de verrouillage 13 est destinée à être pliée le long d'une ligne 12 et le bord libre 19 adjacent au bord 26 du prolongement 17 comporte une barrette 16.The locking tab 13 is intended to be folded along a line 12 and the free edge 19 adjacent to the edge 26 of the extension 17 comprises a bar 16.

Au voisinage de la languette de verrouillage 13 la patte 10 comporte un décrochement 21, un décrochement 22 étant prévu au voisinage de la languette de verrouillage 9 située sur la patte 2.In the vicinity of the locking tab 13 the tab 10 has a recess 21, a recess 22 being provided in the vicinity of the locking tab 9 located on the tab 2.

La fente 14 dans sa partie 14a est légèrement plus large que la partie 5a de la fente 5.The slot 14 in its part 14a is slightly wider than the part 5a of the slot 5.

Comme on le voit aux figures 2 et 3, les pattes 2 et 10 sont pliées pour s'étendre parallèlement et per pendiculairement à la semelle 1, puis le prolongement 4 est plié afin que la barrette 7 vienne porter contre le décrochement 21, le prolongement 17 étant également plié pour que la barrette 16 vienne porter contre le décrochement 22, les languettes de verrouillage 9 et 13 étant enfin rabattues, respectivement contre les prolongements 17 et 4.As seen in Figures 2 and 3, the legs 2 and 10 are folded to extend parallel and per pendulum to the sole 1, then the extension 4 is folded so that the bar 7 comes to bear against the recess 21, the extension 17 also being folded so that the bar 16 comes to bear against the recess 22, the locking tabs 9 and 13 being finally folded down, respectively against extensions 17 and 4.

La figure 4 montre un exemple d'organe de connexion mâle, la semelle 1 étant prolongée pour former un élément 24 destiné à coopérer avec un organe femelle correspondant, par exemple un organe tel que celui représenté à la figure 5 et portant la référence 25.FIG. 4 shows an example of a male connection member, the sole 1 being extended to form an element 24 intended to cooperate with a corresponding female member, for example a member such as that shown in FIG. 5 and bearing the reference 25.

La partie de raccordement électrique B permet de réaliser simultanément et sans avoir à dénuder le conducteur, la liaison électrique et la fixation dudit conducteur. Ce dernier est engagé dans les fentes 5 et 14, cet engagement étant facilité par les parties évasées 5b et 14b. La fente 5 découpe la gaine isolante du conducteur et déforme la section de celui-ci, sans entailler profondément ledit conducteur, de sorte que la connexion électrique est réalisée, tandis que la fente 14 coupe ladite gaine isolante jusqu'au conducteur pour assurer la fixation de ce dernier et, en même temps également le contact électrique.The electrical connection part B allows the electrical connection and the fixing of said conductor to be carried out simultaneously and without having to strip the conductor. The latter is engaged in the slots 5 and 14, this engagement being facilitated by the flared parts 5b and 14b. The slot 5 cuts the insulating sheath of the conductor and deforms the section thereof, without deeply cutting said conductor, so that the electrical connection is made, while the slot 14 cuts said insulating sheath up to the conductor for fixing of the latter and, at the same time also the electrical contact.

A la figure 6, on a représenté une variante de l'invention. Sur cette figure on a utilisé les mêmes références que celles des figures précédentes pour désigner les organes correspondants, mais affectées de la lettre "C".In Figure 6, a variant of the invention is shown. In this figure we used the same references as those of the previous figures to designate the corresponding bodies, but assigned the letter "C".

Les barrettes 7c et 16c sont, dans cette variante, prolongées par des parties 7d et 16d respectivement qui sont destinées à être rabattues contre les faces correspondantes des pattes 2e et 10c. Ainsi, on renforce la liason entre les pattes 2c et 10c et les prolongements 4c et 17c.The bars 7c and 16c are, in this variant, extended by parts 7d and 16d respectively which are intended to be folded against the corresponding faces of the legs 2e and 10c. Thus, the link between the legs 2c and 10c and the extensions 4c and 17c is reinforced.

Les fentes 5c et 14c peuvent également se terminer par un épanouissement 5d et 14d afin d'éviter une contrainte permanente sur le conducteur.The slots 5c and 14c can also end in a blooming 5d and 14d in order to avoid permanent stress on the conductor.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et réprésentés. On pourra y apporter de nombreuses modification de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
