The invention is useful for making connectors for flat cables.

Description

Bande d'éléments de contact à cadre, son procédé de fabrication et son application à des ensembles de contacts La présente invention concerne des éléments de contact à cadre, présentés en bande, ainsi que des ensembles d'élé- ments de contact formés de tels éléments provenant d'une bande . The present invention relates to frame contact elements, presented in a strip, as well as sets of contact elements formed from such strips. items from a tape.
On connaît déjà des éléments de contact à cadre. Ainsi, il existe des éléments de contact comprenant une partie d'enfichage entourée d'un cadre et une partie de raccor- dément destinée au sertissage d'un fil électrique. Un cadre est une partie robuste destinée à protéger mécaniquement la partie d'enfichage. Ces éléments de contact à cadre sont vendus sous forme d ' une bande comprenant une bande porteuse séparable dont un côté porte les parties de raccordement des éléments de contact qui sont séparés mutuellement par une distance de 5,08 mm. Comme la partie de raccordement de chaque élément de contact est sertie sur un fil séparé, les fils peuvent être rapprochés ou écartés à la dimension voulue après sertissage, si bien que l'espacement des élé- ments de contact placés sur la bande porteuse n'a guère d'importance dans cette application.Frame contact elements are already known. Thus, there are contact elements comprising a plug part surrounded by a frame and a connection part intended for crimping an electric wire. A frame is a robust part intended to mechanically protect the plug-in part. These frame contact elements are sold in the form of a strip comprising a separable carrier strip, one side of which carries the connection parts of the contact elements which are separated by a distance of 5.08 mm. As the connection part of each contact element is crimped on a separate wire, the wires can be brought together or spread to the desired dimension after crimping, so that the spacing of the contact elements placed on the carrier strip does not hardly matters in this application.
Par ailleurs, le document WO 88/00762 décrit des éléments de contact dont la partie de raccordement comporte au moins un crevé de forme rectangulaire , ayant deux dents placées à des bords opposés du crevé en direction transversale à la partie de raccordement. Ces éléments de contact, qui sont réalisés en bande qui comporte une bande porteuse fixée à la partie d'enfichage, ont un pas de 2,5 mm. Cette disposition est particulièrement avantageuse dans la mesure où elle permet le raccordement simultané de plusieurs éléments de contact aux conducteurs d'un câble plat à conducteurs au pas de 2 , 5 mm environ . Ce raccordement permet la formation de connecteurs qui sont maintenant très utilisés pour les connexions avec des câbles plats . Les deux réalisations précitées sont incompatibles . En effet, il n'est pas possible de réaliser un cadre pour éléments de contact ayant un pas d'environ 2,5 mm, tel que décrit dans le document précité, avec un pas de 2 , 5 mm étant donné que le cadre doit entourer les quatre côtés de la partie d'enfichage. En conséquence, les cadres destinés à des éléments de contact réalisés avec un pas de 2 , 5 mm ne peuvent être eux-mêmes réalisés qu'avec un pas de l'ordre de 5 mm au moins. Ensuite, les bandes d'éléments de contact décrites dans les documents précités ont une bande porteuse raccordée à la partie d'enfichage puisque les parties de raccordement de plusieurs éléments de contact doivent être connectées simultanément à plusieurs conducteurs d'un câble plat ; il faut donc que les parties de raccordement soient distantes de la bande porteuse. Par ailleurs, les éléments de contact à cadre ayant une partie de raccordement à sertir et réalisés au pas de 5 mm ont une bande porteuse placée du côté de la partie de raccordement. Le document EP—A—0 278 295 décrit des éléments de contact à cuillères doubles qui ne peuvent comporter de rive que d'un seul côté. Le document US—A—5 666 723 décrit des bornes de connecteurs raccordées par une rive et telles qu'il n'existe qu'une seule rive en direction longitudinale. La présente invention concerne des bandes d'éléments de contact à cadre réalisés avec un pas de 2,5 mm, d'une manière qui permet la solution des deux principaux problèmes précités .Furthermore, document WO 88/00762 describes contact elements, the connection part of which comprises at least one puncture of rectangular shape, having two teeth placed at opposite edges of the puncture in a direction transverse to the connection part. These contact elements, which are made of a strip which includes a carrier strip fixed to the insertion part, have a pitch of 2.5 mm. This arrangement is particularly advantageous insofar as it allows the simultaneous connection of several contact elements to the conductors of a flat cable with conductors at a pitch of approximately 2.5 mm. This connection allows the formation of connectors which are now widely used for connections with flat cables. The two aforementioned embodiments are incompatible. Indeed, it is not possible to produce a frame for contact elements having a pitch of approximately 2.5 mm, as described in the aforementioned document, with a pitch of 2.5 mm being since the frame must surround the four sides of the plug part. Consequently, the frames intended for contact elements produced with a pitch of 2.5 mm can themselves be produced only with a pitch of the order of at least 5 mm. Then, the strips of contact elements described in the aforementioned documents have a carrier strip connected to the plug-in part since the connection parts of several contact elements must be connected simultaneously to several conductors of a flat cable; the connection parts must therefore be distant from the carrier strip. Furthermore, the frame contact elements having a connection part to be crimped and produced in steps of 5 mm have a carrier strip placed on the side of the connection part. Document EP-A-0 278 295 describes contact elements with double spoons which can only have a rim on one side. Document US-A-5,666,723 describes connector terminals connected by a bank and such that there is only one bank in the longitudinal direction. The present invention relates to strips of frame contact elements produced with a pitch of 2.5 mm, in a manner which allows the solution of the two main problems mentioned above.
Selon l'invention, ces problèmes sont résolus par combinaison de plusieurs caractéristiques techniques dont les principales sont les suivantes . Des bandes de cadres sont formées avec un pas de 5 mm environ, et deux bandes de tels cadres sont imbriquées l'une dans l'autre afin que, ensemble , elles donnent un pas de 2 , 5 mm environ . Une bande d'éléments de contact est réalisée avec une bande porteuse placée du côté des parties de raccordement, c'est-à-dire du côté opposé à celui de la réalisation connue . Ensuite , les parties d'enfichage de ces éléments de contact sont introduites dans les cadres des bandes superposées et qui ont donc un pas de 2 , 5 mm ; lorsque les éléments de contact sont maintenus par les cadres qui sont solidaires des deux bandes de contact superposées , la bande porteuse placée du côté des parties de raccordement des éléments de contact estAccording to the invention, these problems are solved by combining several technical characteristics, the main ones of which are as follows. Strips of frames are formed with a pitch of approximately 5 mm, and two strips of such frames are nested one inside the other so that, together, they give a pitch of approximately 2.5 mm. A strip of contact elements is produced with a carrier strip placed on the side of the connection parts, that is to say on the side opposite that of the known embodiment. Then, the plug parts of these contact elements are introduced into the frames of the superimposed strips and which therefore have a pitch of 2.5 mm; when the contact elements are held by the frames which are integral with the two superposed contact strips, the carrier strip placed on the side of the connection parts of the contact elements is
FEUILLE DE REMPLACEMENT (RÈGLE 26) supprimée, si bien que l'ensemble obtenu comporte une bande d ' éléments de contact à cadre tenue par une double bande porteuse. Ainsi, les parties de raccordement des éléments de contact sont libres et au pas de 2,5 mm, si bien qu'elles peuvent être raccordées à des câbles plats ayant des conducteurs à un pas de 2,5 mm.SUBSTITUTE SHEET (RULE 26) deleted, so that the assembly obtained comprises a strip of frame contact elements held by a double carrier strip. Thus, the connection parts of the contact elements are free and at a pitch of 2.5 mm, so that they can be connected to flat cables having conductors at a pitch of 2.5 mm.
Plus précisément, l'invention concerne une bande d'éléments de contact à cadre, dans laquelle les éléments de contact sont espacés avec un pas d ' espacement et comportent chacun d'une part un élément de contact possédant une partie de raccordement et une partie d ' enfichage , et , d ' autre part , un cadre entourant au moins partiellement la partie d'enfichage ; selon l'invention, la bande comprend deux bandes de cadres, chaque bande de cadres possédant des cadres tenus par une bande porteuse placée du côté opposé à la partie de raccordement de 1 ' élément de contact correspondant , avec un espacement égal au double du pas d'espacement des éléments de contact, les deux bandes de cadres étant imbriquées et superposées afin que leurs bandes porteuses soient super- posées et que les cadres des deux bandes alternent et forment ainsi ensemble une série de cadres placés d'un même côté des bandes porteuses et ayant un espacement égal au pas des éléments de contact, et un dispositif de solidarisation des bandes porteuses des deux bandes de cadres afin que les éléments de contact à cadre de la bande aient ledit pas d ' espacement .More specifically, the invention relates to a strip of frame contact elements, in which the contact elements are spaced apart with a spacing pitch and each comprise on the one hand a contact element having a connection part and a part of plugging, and, on the other hand, a frame at least partially surrounding the plugging part; according to the invention, the strip comprises two strips of frames, each strip of frames having frames held by a carrier strip placed on the side opposite to the connection part of the corresponding contact element, with a spacing equal to twice the pitch spacing of the contact elements, the two strips of frames being nested and superimposed so that their carrier strips are superimposed and the frames of the two strips alternate and thus together form a series of frames placed on the same side of the strips carriers and having a spacing equal to the pitch of the contact elements, and a device for securing the carrier strips of the two frame strips so that the frame contact elements of the strip have said spacing pitch.
Dans un mode de réalisation, le dispositif de solidarisation comporte des griffes d'une bande porteuse coopérant avec une autre bande porteuse de bande de cadres . De préférence, les bandes porteuses ont des trous de pilotage, et le dispositif de solidarisation est constitué d'un dispositif extérieur de coopération avec les trous de pilotage .In one embodiment, the securing device comprises claws of a carrier strip cooperating with another carrier strip of frame band. Preferably, the carrier strips have pilot holes, and the securing device consists of an external device for cooperation with the pilot holes.
Dans un mode de réalisation particulièrement avanta- geux, la partie de raccordement de l'élément de contact comporte des crevés .In a particularly advantageous embodiment, the connection part of the contact element has punctures.
De préférence, le pas des éléments de contact est égal à 2,5 mm environ . Dans un mode de réalisation, les parties de raccordement des éléments de contact sont solidarisées par une rive disposée sur la longueur de ces parties de raccordement . L ' invention concerne aussi un procédé de fabrication d'une bande d'éléments de contact à cadre, qui comprend les étapes suivantes : la fabrication d'une bande d'éléments de contact espacés avec un pas d'espacement et comportant une partie de raccordement et une partie d'enfichage, la bande ayant une bande porteuse placée du côté des parties de raccordement, la fabrication de deux bandes de cadres possédant chacune des cadres tenus par une bande porteuse , du côté opposé à la partie de raccordement d'un élément de contact avec lequel le cadre est destiné à coopérer, avec un espacement égal au double du pas d'espacement des éléments de contact de la bande d'éléments de contact, la superposition des deux bandes de cadres afin que les cadres soient imbriqués et présentent le pas d'espacement, l'insertion des parties d'enfichage des éléments de contact dans les cadres, et la séparation des parties de raccordement des éléments de contact de la bande porteuse de la bande d'éléments de contact.Preferably, the pitch of the contact elements is approximately 2.5 mm. In one embodiment, the connection parts of the contact elements are joined by an edge disposed along the length of these connection parts. The invention also relates to a method of manufacturing a strip of frame contact elements, which comprises the following steps: the manufacture of a strip of contact elements spaced apart with a spacing pitch and comprising a part of connection and a plug-in part, the strip having a carrier strip placed on the side of the connection parts, the manufacture of two strips of frames each having frames held by a carrier strip, on the side opposite to the connection part of a contact element with which the frame is intended to cooperate, with a spacing equal to twice the spacing pitch of the contact elements of the strip of contact elements, the superposition of the two strips of frames so that the frames are nested and have the spacing pitch, the insertion of the contact parts of the contact elements in the frames, and the separation of the connection parts of the contact elements of the carrier strip of the strip of contact elements.
De préférence, le procédé comporte en outre la solidarisation des deux bandes porteuses des bandes de cadres avant l'insertion des parties d'enfichage des éléments de contact dans les cadres .Preferably, the method further comprises the joining of the two carrier strips of the frame strips before the insertion of the plug-in parts of the contact elements in the frames.
Dans un mode de réalisation particulièrement avantageux, le procédé comporte en outre le raccordement des parties de raccordement des éléments de contact à un câble plat, puis la séparation des bandes porteuses des deux bandes de cadres .In a particularly advantageous embodiment, the method further comprises connecting the connecting parts of the contact elements to a flat cable, then separating the carrier strips from the two frame strips.
L'invention concerne aussi un ensemble d'éléments de contact monté sur un câble souple , réalisé par le procédé précité. D'autres caractéristiques et avantages de l'invention ressortiront mieux de la description qui va suivre d'un exemple de réalisation, faite en référence aux dessins annexés sur lesquels : la figure 1 représente une bande d'éléments de contact réalisés selon 1 ' invention avec un pas de 2 , 5 mm ; la figure 2 représente une bande de cadres dont les cadres ont un pas de 5 mm ; et la figure 3 représente une bande d'éléments de contact à cadre terminée selon 1 ' invention , dans laquelle la bande porteuse des éléments de contact a été supprimée .The invention also relates to a set of contact elements mounted on a flexible cable, produced by the aforementioned method.

In FIG. 1, the carrier strip 12 of the strip of contact elements has pilot holes 14 and is integral with the external end of the connection parts 18 of the contact elements 10.
Dans le document précité WO 88/00762, les éléments de contact 10 sont très semblables à ceux qui sont représentés sur la figure 1, mais la bande porteuse est placée du côté extérieur des parties d'enfichage 16, et les parties de raccordement 18 sont ainsi libres. De cette manière, les éléments de contact 10, encore tenus par leur bande porteuse, peuvent être raccordés à des conducteurs parallèles d'un câble plat.In the aforementioned document WO 88/00762, the contact elements 10 are very similar to those shown in FIG. 1, but the carrier strip is placed on the outside of the plug-in parts 16, and the connection parts 18 are thus free. In this way, the contact elements 10, still held by their carrier strip, can be connected to parallel conductors of a flat cable.
Dans le cas de la bande d'éléments de contact de la figure 1, il n'est pas possible d'utiliser les éléments de contact pour le raccordement à un câble plat ayant des conducteurs parallèles au pas de 2,5 mm, puisque la bande porteuse 12 relie toutes les parties de raccordement. Si les parties de raccordement 18 étaient raccordées à un câble plat, la bande porteuse 12 ne pourrait pas être séparée des parties de raccordement et tous les éléments de contact seraient reliés électriquement par cette bande 12. La bande d'éléments de contact représentée sur la figure 1 est donc un produit nouveau par rapport au produit décrit dans le document précité WO 88/00762. L'invention met aussi en oeuvre des bandes 22 de cadres qui sont destinés chacun à protéger une partie d'enfichage d'élément de contact. Comme l'indique la figure 2, la bande 22 comprend plusieurs cadres 24 dont une extrémité est solidaire d'une bande porteuse 26 qui a des trous de pilotage 28. Dans l'exemple représenté, chaque cadre 24 forme une sorte de boîte allongée ouverte aux deux extrémités , délimitée par des parois 30 et dont la partie supérieure possède une languette élastique 32 permettant la coopération avec un corps de retenue, par exemple d'un boîtier de connecteur. Des cavités 34 peuvent aussi être réalisées en fonction de l'utilisation prévue des cadres. Des pattes 36 formées sur un prolongement du cadre sont destinées à retenir un élément de contact introduit ulté- rieurement.In the case of the strip of contact elements of FIG. 1, it is not possible to use the contact elements for connection to a flat cable having conductors parallel to the pitch of 2.5 mm, since the carrier strip 12 connects all the connection parts. If the connection parts 18 were connected to a flat cable, the carrier strip 12 could not be separated from the connection parts and all the contact elements would be electrically connected by this strip 12. The strip of contact elements shown on the Figure 1 is therefore a new product compared to the product described in the aforementioned document WO 88/00762. The invention also uses strips 22 of frames which are each intended to protect a contact element insertion part. As shown in FIG. 2, the strip 22 comprises several frames 24, one end of which is integral with a carrier strip 26 which has pilot holes 28. In the example shown, each frame 24 forms a kind of open elongated box at both ends, delimited by walls 30 and the upper part of which has an elastic tongue 32 allowing cooperation with a retaining body, for example of a connector housing. Cavities 34 can also be produced depending on the intended use of the frames. Tabs 36 formed on an extension of the frame are intended to retain a contact element introduced later.
Ces caractéristiques peuvent être différentes dans la mesure où les cadres protègent les parties d'enfichage et où ils peuvent être fixés chacun à un élément de contact. Le rôle du cadre est en fait une protection mécanique destinée à éviter la détérioration de la partie d'enfichage lorsque qu'un contact mâle est introduit sans précaution dans l'élément de contact. Le cadre augmente donc la fiabilité des connecteurs réalisés avec de tels éléments de contact.These characteristics can be different insofar as the frames protect the plug-in parts and since they can each be fixed to a contact element. The role of the frame is in fact a mechanical protection intended to avoid deterioration of the plug-in part when a male contact is introduced without care into the contact element. The frame therefore increases the reliability of the connectors produced with such contact elements.
On note sur la figure 2 que les cadres sont très espacés. Ainsi, dans l'exemple représenté, ils ont un pas de 5 mm le long de la bande porteuse 26. Si l'on essaie d'introduire les parties d'enfichage des éléments de contact représentés sur la figure 1 dans les cadres 24, un élément de contact sur deux seulement pénètre dans un cadre . En conséquence, selon l'invention, deux bandes de cadres 22, telles que représentées sur la figure 2 , sont imbriquées , avec leurs bandes porteuses 26 superposées et solidarisées. De cette manière , 1 ' ensemble des deux bandes de cadres possède des cadres espacés avec un pas de 2,5 mm. On note en outre sur la figure 2 des griffes 38 qui permettent la solidarisation des deux bandes porteuses 26 des bandes de cadres. Les bandes porteuses 26 sont réalisées afin qu'elles puissent être superposées avec un décalage de 2,5 mm suivant leur longueur. Les trous de pilotage 28 sont par exemple séparés par une distance de 2,5 mm.Note in Figure 2 that the frames are widely spaced. Thus, in the example shown, they have a pitch of 5 mm along the carrier strip 26. If we try to introduce the plug-in parts of the contact elements shown in FIG. 1 in the frames 24, only one contact element out of two enters a frame. Consequently, according to the invention, two bands of frames 22, as shown in FIG. 2, are nested, with their carrier bands 26 superimposed and secured. In this way, the assembly of the two frame strips has frames spaced apart with a pitch of 2.5 mm. Note also in Figure 2 claws 38 which allow the joining of the two carrier strips 26 of the frame bands. The carrier strips 26 are made so that they can be superimposed with an offset of 2.5 mm depending on their length. The pilot holes 28 are for example separated by a distance of 2.5 mm.
L ' imbrication des deux bandes de cadres donne ainsi une bande résultante ayant des cadres avec un pas de 2,5 mm. Il est alors simple d'introduire les parties d'enfichage des éléments de contact ayant un pas de 2,5 mm, comme représenté sur la figure 1, par l'extrémité ouverte des cadres 24 opposée à la bande porteuse . L ' opération est réalisée par mise en oeuvre de techniques classiques, assurant par exemple l'alignement de chaque élément de contact et du cadre correspondant juste avant l'introduction, et le guidage mutuel de 1 ' élément et du cadre . Lorsque les éléments de contact ont ainsi été introduits dans les cadres et après que les pattes 36 des cadres ont été serties sur les élé- ments de contact pour les maintenir, la bande porteuse 12 des éléments de contact est séparée des parties de raccordement des éléments de contact, si bien qu'on obtient la disposition indiquée sur la figure 3. Dans cette disposition, les parties de raccordement à crevés peuvent être raccordées à des câbles plats, puisqu'elles sont présentées de la même manière que les bandes d'éléments de contact décrites dans le document précité WO 88/00762. Cependant, les éléments de contact comportent des cadres .The overlapping of the two strips of frames thus gives a resulting strip having frames with a pitch of 2.5 mm. It is then simple to introduce the plug-in parts of the contact elements having a pitch of 2.5 mm, as shown in FIG. 1, through the open end of the frames 24 opposite the carrier strip. The operation is carried out by implementing conventional techniques, ensuring for example the alignment of each contact element and of the corresponding frame just before the introduction, and the mutual guidance of the element and the frame. When the contact elements have thus been introduced into the frames and after the tabs 36 of the frames have been crimped onto the contact elements to hold them, the carrier strip 12 of the contact elements is separated from the connecting parts of the elements contact, so that we obtain the arrangement indicated in Figure 3. In this arrangement, the puncture connection parts can be connected to flat cables, since they are presented in the same way as the strips of elements of contact described in the aforementioned document WO 88/00762. However, the contact elements include frames.
On a indiqué , sur la figure 3 , la présence de griffes de solidarisation 38. Bien qu'un dispositif de solidarisation des deux bandes porteuses des deux bandes de cadres superposées et imbriquées soit nécessaire au moment de la présentation des parties d'enfichage et de la connexion à un câble plat, ce dispositif peut être de type quelconque. Il peut comprendre des griffes, des soudures, des languettes pliées ou simplement une retenue par des organes de pilotage du dispositif de déplacement de la bande porteuse. La solidarisation peut aussi être assurée par d'autres moyens, par exemple par collage des deux bandes porteuses 26. L'invention concerne aussi un procédé dans lequel une bande d'éléments de contact est réalisée de manière que sa bande porteuse soit placée du côté des parties de raccordement des éléments de contact, puis une bande de cadres est 8 réalisée afin qu ' elle ait un pas efficace identique à celui des éléments de contact, et, lorsque les éléments de contact ont été introduits dans les cadres et sont maintenus par les bandes porteuses des bandes de cadres , la bande porteuse des parties de raccordement des éléments de contact est supprimée .It has been indicated, in FIG. 3, the presence of fastening claws 38. Although a device for fastening the two carrying bands of the two superimposed and overlapping bands of frames is necessary at the time of the presentation of the plug-in parts and of connection to a flat cable, this device can be of any type. It may include claws, welds, folded tabs or simply a retainer by the control members of the device for moving the carrier strip. The connection can also be ensured by other means, for example by bonding the two carrier strips 26. The invention also relates to a method in which a strip of contact elements is produced so that its carrier strip is placed on the side connecting parts of the contact elements, then a strip of frames is 8 made so that it has an effective pitch identical to that of the contact elements, and, when the contact elements have been introduced into the frames and are held by the carrier bands of the frame bands, the carrier band of the connecting parts contact items is deleted.
L'invention concerne aussi des éléments de connexion pour câble plat comprenant des éléments de contact à cadres , obtenus par sertissage des crevés 20 des parties de raccor- dément 18 sur les conducteurs parallèles d'un câble plat, puis par découpe des bandes porteuses de support des cadres . Il est ainsi possible de réaliser des connecteurs à un pas de 2,5 mm, utiles par exemple dans les appareils électroniques , notamment les appareils électroménagers , ou pour les circuits de câblage électrique des automobiles.The invention also relates to connection elements for flat cable comprising frame contact elements, obtained by crimping the punctures 20 of the connection parts 18 on the parallel conductors of a flat cable, then by cutting the carrier strips of frame support. It is thus possible to produce connectors with a pitch of 2.5 mm, useful for example in electronic devices, in particular household appliances, or for electric wiring circuits of automobiles.
Bien qu'on ait décrit des bandes porteuses comprenant des trous de pilotage, il est bien évident que d'autres moyens permettant l'avance des bandes et leur positionnement peuvent être utilisés. En particulier, la figure 1 indique, en traits interrompus, une variante avantageuse au point de vue de la rentabilité . Sur la figure 1 , la rive 12 ayant les trous de pilotage 14 peut être supprimée, au niveau du trait interrompu 44, et une "rive" 40 est formée entre les parties 18 de raccordement, avec des trous de pilotage 42. La bande de métal utilisée peut alors être plus étroite, d'une dimension correspondant à la rive, et des économies de métal sont ainsi réalisées. Cette "rive" 40 peut occuper tout emplacement commode le long des contacts, et elle est supprimée non par découpe longitudinale, mais par des découpes transversales.Although carrier bands comprising pilot holes have been described, it is obvious that other means allowing the bands to advance and their positioning can be used. In particular, Figure 1 indicates, in broken lines, an advantageous variant from the point of view of profitability. In FIG. 1, the bank 12 having the pilot holes 14 can be omitted, at the level of the broken line 44, and a "bank" 40 is formed between the connecting parts 18, with pilot holes 42. The strip of metal used can then be narrower, of a dimension corresponding to the bank, and metal savings are thus realized. This "shore" 40 can occupy any convenient location along the contacts, and it is eliminated not by longitudinal cutting, but by transverse cuts.
On a décrit 1 ' invention dans le cas d ' éléments de contact au pas de 2,54 mm et de cadres au pas de 5,08 mm, mais elle n'est pas limitée à ces dimensions. Par exemple, elle s'applique à des éléments de contact au pas de 1,27 mm et à des cadres au pas de 2,54 mm, ou, au contraire, à des pas plus grands . De même , bien qu ' on ait décrit 1 ' invention dans sa mise en oeuvre par utilisation d'une bande d'éléments de contact pour deux bandes de cadres , elle s ' appliqueThe invention has been described in the case of contact elements with a pitch of 2.54 mm and frames with a pitch of 5.08 mm, but it is not limited to these dimensions. For example, it applies to contact elements with a pitch of 1.27 mm and frames with a pitch of 2.54 mm, or, on the contrary, with larger steps. Similarly, although the invention has been described in its implementation by the use of a strip of contact elements for two strips of frames, it applies
FEUILLE DE REMPLACEMENT (RÈGLE 26) aussi, avec des modifications évidentes, à l'utilisation d'une bande d'éléments de contact pour trois bandes de cadres ou plus .SUBSTITUTE SHEET (RULE 26) also, with obvious modifications, the use of a strip of contact elements for three or more strips of frames.
On a décrit l'invention dans le cas d'éléments de contact qui sont solidarisés au cadre correspondant par sertissage des pattes 36 sur une partie de l'élément de contact. Cependant, d'autres dispositifs peuvent être utilisés , par exemple un simple point de soudure entre deux parois adjacentes du cadre et de la partie d'enfichage, ou la coopération élastique d'une saillie et d'une cavité. De même, cette fixation relative peut être obtenue par coopération du cadre d'une part et de l'élément de contact d'autre part avec un même organe, par exemple un boîtier de connecteur destiné à contenir plusieurs contacts. II est bien entendu que l'invention n'a été décrite et représentée qu'à titre d'exemple préférentiel et qu'on pourra apporter toute équivalence technique dans ses éléments constitutifs sans pour autant sortir de son cadre. The invention has been described in the case of contact elements which are secured to the corresponding frame by crimping the tabs 36 on a part of the contact element. However, other devices can be used, for example a simple spot of welding between two adjacent walls of the frame and the plug-in part, or the elastic cooperation of a projection and a cavity. Likewise, this relative fixing can be obtained by cooperation of the frame on the one hand and of the contact element on the other hand with the same member, for example a connector housing intended to contain several contacts. It is understood that the invention has only been described and shown as a preferred example and that any technical equivalence may be made in its constituent elements without going beyond its ambit.
