Abstract

An unearthed two-pin electric plug is provided. To avoid the need for tools when wiring, the plug includes a blade (2, 22, 62) rotating about the axis of a hinge which is parallel or perpendicular to the axis of the electric lead. In the two fullest embodiments of the plug, projections co-operate to split, position and connect up the lead. In one embodiment, the inner surface of the lower plug portion includes a base (80) with grooves (71, 72, 73) engaged by tapered splitting portions (51, 52, 53) which push the two conductors of the lead sideways so that they slide over the base (80) and are caught on contact spikes (5) at almost the same time as said lead is cut by the central blade (62). The lead is held in position by a filler bar (50) and by the splitting portions (51, 53) which drive the lead sideways so that it winds through recesses (81, 83).

Description

L'invention se rapporte au domaine des prises électriques à deux fiches,pour câble souple,comportant deux brins accolés latéralement.The invention relates to the field of electrical sockets with two plugs, for flexible cable, comprising two strands joined sideways.

Elle a pour but de rendre inutile toute utilisation d'outils,tels que couteaux,tournevis,pince à dénuder, généralement indispensables pendant l'opération de raccordement de la prise au câble,ainsi que de la rendre plus aisée et plus rapide encore que dans les cas des réalisations antérieures qui se sont données d'atteindre un but similaire.Its purpose is to make unnecessary any use of tools, such as knives, screwdrivers, stripping pliers, generally essential during the operation of connecting the plug to the cable, as well as to make it easier and faster even than in the cases of previous achievements which have given themselves to achieve a similar goal.

Ces réalisations antérieures n'ont toutefois pas réussi à supprimer toute utilisation d'outils pour la connexion.These previous achievements, however, have not succeeded in eliminating all use of tools for connection.

C'est le cas des brevets Suisse 383 458,et U.S. 2658 184 et 4 842 546 cités ci-après respectivement comme les documents D1,D2, et D3.This is the case of the Swiss patents 383,458, and U.S. 2,658,184 and 4,842,546 cited below respectively as documents D1, D2, and D3.

Dans D1,une vis,faisant partie du dispositif,ne peut être vissée qu'avec un tournevis ou une pièce de monnaie faisant office de tournevisIn D1, a screw, part of the device, can only be screwed with a screwdriver or a coin acting as a screwdriver

Dans D1,D2 et D3 l'absence d'un moyen adéquat fait que si le câble électrique n'est pas égal,il faut une pince coupante pour l'égaliser à son extrêmité.In D1, D2 and D3 the absence of an adequate means means that if the electric cable is not equal, you need a cutting pliers to equalize it at its end.

Dans D2 et D3 il n'y a pas de dispositif de séparation des brins du câble,là encore un outil coupant est nécessaire d'autant que les câbles électriques à deux conducteurs comportent aujourd'hui une gaine extérieure qui englobe les deux brins. Le préambule de la revendication 1 est basé sur cet état de la technique.In D2 and D3 there is no device for separating the strands of the cable, here again a cutting tool is necessary, especially since the electric cables with two conductors today have an outer sheath which encompasses the two strands. The preamble of claim 1 is based on this state of the art.

Dans D1 le moyen de séparation ponctuelle des deux brins du câble,par vis conique,nécessite de la force lorsque le câble électrique comporte cette troisième gaine qui enferme les deux brins.Ce système de vis conique ne permet pas non plus d'imposer au brins un méandre suffisamment marqué pour permettre à lui seul le blocage du câble en cas de traction sur la prise.La courbe que font les brins le montre bien (cf D1 fig 2 et 5).De plus cette courbe résultant de l'écartement des brins est le lieu même de la connexion .De ce fait une traction exercée sur le câble s'applique sur les moyens de connexion même et risque fortement de les endommager et ce d'autant plus qu'ils se présentent,tout comme le dispositif selon nos variantes de réalisation,sous la forme de dents métalliques acérées donc fragiles à leur extrêmité. Dans le document D2 le moyen de blocage du câble par stries (33) figures (1,4,5) ne semble pas non plus très efficace.In D1 the point separation means of the two strands of the cable, by conical screw, requires force when the electric cable has this third sheath which encloses the two strands.This conical screw system also does not allow to impose on the strands a meander sufficiently marked to allow the cable to block itself in the event of traction on the socket. The curve made by the strands shows this well (see D1 fig 2 and 5). In addition, this curve resulting from the spacing of the strands is the very place of the connection. As a result a traction exerted on the cable applies to the connection means itself and is highly likely to damage them and this all the more so as they arise, just like the device according to our variant embodiments, in the form of sharp metal teeth therefore fragile at their ends. In document D2, the means for blocking the cable by striations (33) in figures (1,4,5) does not seem very effective either.

La présente invention, telle que définie dans la revendication 1, remèdie à ces défauts.The present invention, as defined in claim 1, remedies these defects.

Dans les trois variantes de réalisation présentées ici la découpe et la connexion du câble électrique se font dans le geste de fermeture de la prise.In the three variant embodiments presented here, the cutting and connection of the electric cable is done by closing the socket.

Dans la deuxième variante de réalisation le câble ést de plus mis en place automatiquement et enfin dans la troisième la plus complète,en même temps que la connexion la fermeture de la prise provoque un méandre dans le trajet des brins du câble,de telle sorte que la traction même forte qui peut s'exercer sur le câble n'est pas ressentie au niveau de la partie des brins servant à la connexion et donc aucune tension n'est exercée non plus sur les moyens de contact de la prise.In the second variant embodiment, the cable is also placed automatically and finally in the third most complete, at the same time as the connection, the closing of the socket causes a meander in the path of the strands of the cable, so that even the strong traction which can be exerted on the cable is not felt at the level of the part of the strands used for the connection and therefore no tension is exerted either on the contact means of the socket.

Les trois variantes de réalisation ont donc en commun:
   -L'utilisation d'au moins trois aiguilles ou épines de contact espacées par exemple longitudinalement d'au moins 5 mm et latéralement de telle sorte que le coeur de chaque brin du câble puisse être atteint dans le tiers gauche,le tiers droit et dans le milieu de sa section,orientées vers ledit coeur conducteur selon la direction de déplacement du brin lors de l'opération de perçage dudit brin,de longueur suffisante pour percer ce coeur de part en part.Lesdites aiguilles ou épines de contact étant d'épaisseur,à leur base,égale au minimum à trois dixièmes de millimètres,ou par exemple au tiers du diamètre du coeur conducteur,et lesdites aiguilles ou épines faisant partie intégrante des fiches,mâle ou femelle de la prise.Les pointes et les arêtes de ces éléments devant être vives sinon acérées ou affutées.
The three variants therefore have in common:
-The use of at least three contact needles or spines spaced apart, for example longitudinally at least 5 mm and laterally so that the heart of each strand of the cable can be reached in the left third, the right third and in the middle of its section, oriented towards said conductive core in the direction of movement of the strand during the drilling operation of said strand, of sufficient length to pierce this heart right through. Said contact needles or spines being thick , at their base, equal to at least three tenths of a millimeter, or for example to a third of the diameter of the conductive core, and said needles or thorns being an integral part of the plugs, male or female of the socket. items to be sharp if not sharp or sharp.

Leur utilisation,on l'aura compris,supprime le dénudage et ensuite le coincement par vissage du fil dénudé.Their use, it will be understood, removes the stripping and then the jamming by screwing of the stripped wire.

L'incorporation à la prise,d'une lame ayant un profil transversal en "T"pour être bien ancrée et stable dans le bloc de plastique dans lequel elle est en partie noyée,de longueur et de hauteur telles que dans le mode de réalisation le plus complet de l'invention,le câble soit tranché jusqu'à son extrêmité située dans la prise, avant que ses brins ne soient guidés dans leur logement.The incorporation into the socket, of a blade having a transverse "T" profile to be well anchored and stable in the plastic block in which it is partially embedded, of length and height as in the embodiment the most complete of the invention, the cable is cut to its end located in the socket, before its strands are guided in their housing.

Cette incorporation,on l'aura compris ,supprime l'utilisation d'un couteau pour désolidariser les deux brins du câble électrique.This incorporation, it will be understood, eliminates the use of a knife to separate the two strands of the electric cable.

Le découpage,intégré à la prise suppose que ladite lame agisse en rotation autour d'un axe ,cet axe de rotation étant soit parallèle à l'axe longitudinal du câble ,soit au contraire perpendiculaire à cet axe.The cutting, integrated into the socket supposes that said blade acts in rotation about an axis, this axis of rotation being either parallel to the longitudinal axis of the cable, or on the contrary perpendicular to this axis.

Dans la première variante de réalisation,l'axe de rotation de la charnière,est parallèle à l'axe longitudinal du câble mis en place,et dans les deux suivantes cet axe de rotation est perpendiculaire à l'axe longitudinal du câble mis en place.In the first alternative embodiment, the axis of rotation of the hinge is parallel to the longitudinal axis of the cable installed, and in the following two this axis of rotation is perpendicular to the longitudinal axis of the cable installed .

Selon la première variante de réalisation ,les fiches mâles et femelle sont découpées longitudinalement selon le plan contenant un diamètre de chacune des deux fiches mâles ou de chacune des deux fiches femelles selon le type de prise.Ce plan sera désigné dans ce qui suit et dans les revendications sous l'appelation de"plan longitudinal médian des fiches" ou plus simplement sous l'appelation de "plan longitudinal médian".According to the first embodiment, the male and female plugs are cut longitudinally along the plane containing a diameter of each of the two male plugs or of each of the two female plugs depending on the type of plug. This plane will be designated in the following and in the claims under the designation "median longitudinal plane of the sheets" or more simply under the designation "median longitudinal plane".

Dans le cas des prises mâles la partie des fiches,intégrée au bloc de plastique ,est creusée de façon à servir de logement de contact pour les câbles.Le diamètre intérieur de ces parties intégrées semi-cylindriques est légèrement supérieur au diamètre extérieur d'un brin du plus gros des câbles admissibles par la prise. Dans le cas des prises femelles,le diamètre intérieur de la partie intégrée est naturellement égal au diamètre extérieur de la fiche mâle Le logement de contact est alors constitué d'un demi-cylindre de même forme et dimension que pour la prise mâle .Dans les deux cas les logements de contact ont sur leur moitié de section semi-cylindrique,un réhaussement plat du fond,réduisant d'un quart de son rayon la hauteur totale du logement de contact pour écraser le brin du câble et ainsi mieux le maintenir en place.Les deux moitiés,de réception et couvrante des prise mâle ou femelle ,comportent en plus un dispositif de contact entre leur dite moitié couvrante et de réception sous forme d'autres fiches mâles et femelles,dans la prise elle-même ,et dont le profil transversal est une sorte de vase inversé ,plus large en haut qu'en bas arrondi au sommet et fendu en deux .Ce dispositif fait en même temps office de fermeture pression de l'ensemble.Les aiguilles ou épines de contact se trouvent dressées sur le fond de la moitié de réception des logements de contact.In the case of male sockets, the part of the plugs, integrated into the plastic block, is hollowed out so as to serve as a contact housing for the cables. The internal diameter of these semi-cylindrical integrated parts is slightly greater than the external diameter of a strand of the largest of the admissible cables through the socket. In the case of female sockets, the internal diameter of the integrated part is naturally equal to the external diameter of the male plug. The contact housing then consists of a half-cylinder of the same shape and size as for the male socket. two cases the contact housings have on their semi-cylindrical section half, a flat raising of the bottom, reducing by a quarter of its radius the total height of the contact housing to crush the strand of the cable and thus better hold it in place .The two halves, for receiving and covering the male or female socket, further include a contact device between their said covering half and for receiving in the form of other male and female plugs, in the socket itself, and the transverse profile is a kind of inverted vase, wider at the top than at the bottom rounded at the top and split in two. This device simultaneously acts as a pressure closure of the assembly. are located on the bottom of the receiving half of the contact housings.

Selon les variantes de réalisation avec la charnière perpendiculaire à l'axe longitudinal du câble,les fiches mâles et femelles qui ne sont plus découpées selon le plan longitudinal médian comportent des aiguilles ou épines de contact sur leur surface extérieure ,fiches plus épines ne formant donc qu'un seul bloc.According to the variant embodiments with the hinge perpendicular to the longitudinal axis of the cable, the male and female plugs which are no longer cut along the median longitudinal plane have contact needles or thorns on their outer surface, therefore more thorny plugs do not form only one block.

Selon la première de ces variantes de réalisation,pour que le raccordement se fasse en une seule opération,sans accroc il est nécessaire que le câble soit entièrement tranché avant que ses deux brins soient dirigés par un bloc dit "de pressage",en glissant le long d'une pente dite de glissement inclinée à au moins 40° par rapport au plan longitudinal médian des fiches,les deux pentes de glissement faisant saillie d'écartement ,dont le profil transversal est complémentaire à celui du bloc de pressage,qui est en creux,avant donc d'être dirigés chacun vers son logement de contact au fond duquel se trouvent les aiguilles ou épines de contact ,orientées dans la même direction que la surface des pentes de glissement et que l'axe passant par les centres des circonférences des fiches(mâles ou femelles)et des brins du câble une fois au fond de leur logement de contact.Le bloc de pressage comporte des arêtes qui râclent les pentes de glissement et qui forment l'arête interne de la face supérieure des gouttières de guidage et du logement de contact.La hauteur totale de la cavité formée par le logement de contact et sa gouttière de guidage supérieure,est inférieure d'un quart de rayon au diamètre du plus gros des brins des câbles admissibles par la prise.According to the first of these variant embodiments, for the connection to be made in a single operation, without a hitch, it is necessary that the cable is completely cut before its two strands are directed by a so-called "pressing" block, by sliding the along a so-called sliding slope inclined at least 40 ° relative to the median longitudinal plane of the plugs, the two sliding slopes projecting apart, the transverse profile of which is complementary to that of the pressing block, which is in hollow, before therefore being each directed towards its contact housing at the bottom of which are the contact needles or spines, oriented in the same direction as the surface of the sliding slopes and the axis passing through the centers of the circumferences of the plugs (male or female) and strands of the cable once at the bottom of their contact housing. The pressing block has edges which scrape the sliding slopes and which form the edge in dull of the upper face of the guide gutters and the contact housing. The total height of the cavity formed by the contact housing and its upper guide gutter is less than a quarter of a radius smaller than the diameter of the largest strands of the cables admissible by the socket.

Pour que le déplacement des brins des suive le découpage complet du câble,il est nécessaire que la lame ait certaines caractéristiques.In order for the movement of the strands to follow the complete cutting of the cable, the blade must have certain characteristics.

Il faut:
   que l'angle de son extrêmité antérieure (angle δ) ait une valeur égale à 90°-α.
   que sa hauteur "h"à la même extrêmité soit au moins égale à: h= l₁. tgα+ D/sinδ + AD + E/2. (où l₁ est la longueur du brin de câble parallèle au plan longitudinal médian,dans le logement de contact, α l'angle dans le plan normal au plan longitudinal médian ,selon lequel décline le brin,D le diamètre du plus gros des brins des câbles admissibles par la prise,AD la distance d'enfoncement du brin,E l'épaisseur de la zone arrière supérieure de la partie passive. La longueur du tranchant de la lame doit être au moins égale à l₁ + la longueur de la portion de câble qui descend et qui donc est inclinée et dont on verra la valeur plus loin.
It is necessary:
that the angle of its anterior end (angle δ) has a value equal to 90 ° -α.
that its height "h" at the same end is at least equal to: h = l₁. tgα + D / sinδ + AD + E / 2. (where l₁ is the length of the cable strand parallel to the median longitudinal plane, in the contact housing, α the angle in the plane normal to the median longitudinal plane, along which the strand declines, D the diameter of the largest of the strands cables admissible by the socket, AD the penetration distance of the strand, E the thickness of the upper rear zone of the passive part.The length of the edge of the blade must be at least equal to l + the length of the portion of cable which descends and which is therefore inclined and whose value will be seen later.

Selon la deuxième et la plus récente de ces variantes à axes perpendiculaires,le raccordement se fait aussi en une seule opération et peut avoir lieu pendant la coupe du câble.La face interne de la partie active comporte ,comme dans le cas précédent,des reliefs qui coopèrent avec ceux de la face interne de la partie passive,pour écarter mettre en place et connecter le câble à la prise.According to the second and most recent of these variants with perpendicular axes, the connection is also made in a single operation and can take place during the cutting of the cable. of the active part comprises, as in the previous case, reliefs which cooperate with those of the internal face of the passive part, in order to separate set up and connect the cable to the socket.

La face interne de la partie active comporte donc une poutre de remplissage (50) et de maintien en place des brins du câble séparés par la lame (62) et écartés par les coins de séparation ou écarteurs (51,52,53) au nombre par exemple de trois ,qui pénètrent dans leur logement respectif (71,72,73) situés sur la face interne de la partie passive de la prise.Cette partie passive comporte une surface parallèle au plan longitudinal médian des fiches,appelée le sol (80),de glissement des brins (104) du câble ,le glissement s'opèrant pendant que les coins de séparation pénètrent dans leur logement tout en écartant et connectant les brins du câble.L'action des écarteurs coniques(51,52,53) qui amorcent la connexion qui sera obtenuepar percement de l'isolant,est facilitée,complètée,et terminée par la poutre de remplissage (50) qui assure la pénétration maximum possible des épines(4) ou aiguilles (5) de contact dans le coeur conducteur même d'un brin du câble.La poutre de remplisage garantit aussi avec les écarteurs,et tant que la prise est fermée que les brins du câble sont serrés et bien en place.Les écarteurs avant (51) et arrière (53) au moins,ont une largeur maximum supérieure à celle de la poutre de remplissage (50),alors que latéralement et vis à vis d'eux ,les parois (85) du réceptacle sont creusées,de sorte que chaque brin doit faire un méandre .Ce dispositif sert de blocage de chaque brin du câble ,pour empêcher son déplacement lors de tractions accidentelles qui s'exerceraient sur lui ,évitant ainsi les dommages aux épines de contact ou la déconnexion intempestive de l'ensemble.The internal face of the active part therefore comprises a filling beam (50) and holding in place the strands of the cable separated by the blade (62) and separated by the separation corners or spacers (51,52,53) in number for example three, which enter their respective housing (71,72,73) located on the internal face of the passive part of the catch. This passive part comprises a surface parallel to the median longitudinal plane of the plugs, called the ground (80 ), of sliding of the strands (104) of the cable, the sliding taking place while the separation corners penetrate into their housing while spreading and connecting the strands of the cable. The action of the conical spacers (51,52,53) which initiate the connection which will be obtained by piercing the insulation, is facilitated, completed, and terminated by the filling beam (50) which ensures the maximum possible penetration of the thorns (4) or contact needles (5) in the conductive core even a strand of the cable. re-filling also guarantees with the spacers, and as long as the plug is closed that the cable strands are tight and securely in place. The front spacers (51) and rear (53) at least, have a maximum width greater than that of the filling beam (50), while laterally and opposite them, the walls (85) of the receptacle are hollowed out, so that each strand must make a meander. This device serves to block each strand of the cable, to prevent its displacement during accidental pulls which would be exerted on it, thus avoiding damage to the contact spines or inadvertent disconnection of the assembly.

Only figures 3,5,7,9,11,13,14 have a reference value, the dimensions being generally respected there.

There was a need only for the wedging edge and the two edges of the scraper as well as for the hollow reliefs of the passive part of the three alternative embodiments. The other angles can be rounded.

Exposé détaillé de trois variantes de réalisation selon l'invention.Detailed description of three variant embodiments according to the invention.

La variante la plus classique est celle où la prise est en deux parties:un boitier extérieur dans lequel est encastré un bloc contenant les deux fiches.Dans cette variante de réalisation,les axes de la charnière et du câble électrique,sont parallèles.La description dans ce cas ne porte que sur le bloc.The most classic variant is that in which the plug is in two parts: an external box in which a block containing the two plugs is embedded. In this variant, the axes of the hinge and of the electric cable are parallel. in this case only relates to the block.

Il faut se référer aux figures 1,2 et 3Refer to Figures 1,2 and 3

Sur la figure 1qui est un exemple de prise mâle,le bloc est découpé en deux moitiés,une passive (12) et une active (11) articulées autour d'une charnière (1).Au milieu de la partie active (11) on remarque la lame (2) servant à couper le câble longitudinalement pour séparer ses deux brins,après avoir éventuellement égalisé le câble en son extrêmité grâce à l'action de la lame (2) obtenue en rabattant la partie active (11) sur la partie passive (12) sur le câble présenté perpendiculairement à l'axe longitudinal de la cavité (3) de la lame (2).In Figure 1, which is an example of a male plug, the block is cut into two halves, a passive (12) and an active (11) articulated around a hinge (1). In the middle of the active part (11) we note the blade (2) used to cut the cable longitudinally to separate its two strands, after having possibly equalized the cable at its end thanks to the action of the blade (2) obtained by folding the active part (11) over the part passive (12) on the cable presented perpendicular to the longitudinal axis of the cavity (3) of the blade (2).

Les fiches (13) sont divisées en deux moitiés pleines à l'extérieur des parties (11 ou 12) du bloc alors qu'à leur intérieur la zone intégrée (7) desdites fiches est creuse .Les fiches(13+7) ne font qu'une seule pièce avec,pour la partie passive(12) une cavité de contact(8) et pour la partie active (11) les fiches de contact (9).Ces fiches (9) et la cavité (8) ont des formes complémentaires,les fiches (9) étant les éléments mâles d'une sorte de prise à l'intérieur d'une sorte de prise dans la prise elle-même,de façon à ce que les deux moitiés externes des fiches (13) soient bien parcourues par le même courant.Les fiches (9) ont un profil transversal comportant une étroitesse relative à la base puis sévasant vers le haut,puis se recourbant pour se refermer jusqu'à la fente centrale (10).Grâce à ce profil,les parties (8) et (9) jouent le rôle de blocage du bloc entier en position fermé.L'ensemble fonctionne de la manière suivante:The cards (13) are divided into two solid halves on the outside of the parts (11 or 12) of the block while inside them the integrated area (7) of said cards is hollow. The cards (13 + 7) do not only one piece with, for the passive part (12) a contact cavity (8) and for the active part (11) the contact plugs (9). These plugs (9) and the cavity (8) have complementary forms, the plugs (9) being the male elements of a sort of socket inside a sort of socket in the socket itself, so that the two external halves of the plugs (13) are well traversed by the same current. The cards (9) have a transverse profile comprising a narrowness relative to the base then shattering upwards, then bending to close up to the central slot (10). Thanks to this profile, the parts (8) and (9) play the role of blocking the entire block in the closed position. The assembly operates as follows:

Après avoir découpé le câble longitudinalement en l'ayant posé sur la cavité (3) de la lame et en l'ayant bien centré en plaçant la lame de sorte qu'elle soit bien sur toute la longueur à découper,du câble,entre les deux brins ,avant la pression,on relève la partie active (11) et l'on dépose chaque brin dans chaque partie intérieure (7) pour la prise femelle ou (16) pour la prise mâle,des fiches (13).Il ne reste qu'à refemer lentement mais avec force la partie active (11) sur la partie passive (12).After having cut the cable longitudinally by having placed it on the cavity (3) of the blade and having well centered it by placing the blade so that it is well over the entire length to be cut, of the cable, between the two strands, before pressing, the active part (11) is raised and each strand is placed in each interior part (7) for the female socket or (16) for the male socket, plugs (13). All that remains is to slowly but forcefully reseal the active part (11) on the passive part (12).

Sur les figures 1 et 2,les aiguilles de contact(5) ou les épines de contact (4) sont dessinées sur la partie active(11) du bloc.Mais il y a une autre possibilité c'est qu'elles soient dans la partie passive (12) Dans ce dernier cas l'utilisateur devra d'abord après avoir séparé les deux brins du câble,les piquer à la main,sur les aiguilles ou épines de contact,sans forcer juste pour qu'elles pénètrent dans la gaine de chaque brin du câble;cest en refermant l'ensemble que les aiguilles ou épines pénétreront jusqu'au coeur conducteur du câble.Sur le dessin nous avons figuré les deux types de formes de contacts.Il va de soi que l'une ou l'autre de ces formes est utilisable mais qu'il serait fantaisiste de mettre des aiguilles dans une cavité et des épines dans l'autre.In Figures 1 and 2 , the contact needles (5) or the contact spines (4) are drawn on the active part (11) of the block, but there is another possibility is that they are in the passive part (12) In the latter case the user must first, after having separated the two strands of the cable, prick them by hand, on the contact needles or spines, without forcing just so that they penetrate the sheath of each strand of the cable; it is by closing the assembly that the needles or thorns will penetrate to the conductive core of the cable. In the drawing we have shown the two types of contact forms. It goes without saying that one or the Another of these forms is usable but it would be fanciful to put needles in one cavity and thorns in the other.

Sur la figure 3,une vue transversale très agrandie de la pièce métallique constituant la zone intégrée(7) de la fiche femelle et le demi-cylindre(16),on peut distinguer la position des épines ou aiguilles de contact (4,5),et leur longueur qui doit être très légèrement supérieure à l'épaisseur de la gaine (101)additionnée du diamètre du coeur conducteur (102) du plus épais des brins des câbles admissibles par la prise.Les aiguilles ou épines de contact sont décalées latéralement,à leur base,d'une distance à peu près égale à leur propre épaisseur "e",soit un tiers du diamètre du coeur (102) avec un minimum de trois dixièmes de millimètres et disposées de façon telle que l'une d'entr'elles soit dans le plan longitudinal central, d'un brin du câble,plan qui est lui-même perpendiculaire au plan longitudinal médian des fiches,et les autres réparties à sa droite et à sa gauche.Il faut encore remarquer le plat (17) servant à éviter tout jeu du brin du câble dans le demi-cylindre (16) autrement appelé logement de contact.In FIG. 3 , a very enlarged transverse view of the metal part constituting the integrated zone (7) of the female plug and the half-cylinder (16), we can distinguish the position of the spines or contact needles (4,5) , and their length which must be very slightly greater than the thickness of the sheath (101) plus the diameter of the conductive core (102) of the thickest of the strands of the cables admissible by the plug. The contact needles or spines are offset laterally , at their base, a distance approximately equal to their own thickness "e", or one third of the diameter of the core (102) with a minimum of three tenths of a millimeter and arranged in such a way that one of between them is in the central longitudinal plane, of a strand of the cable, a plane which is itself perpendicular to the median longitudinal plane of the plugs, and the others distributed to its right and to its left. 17) used to avoid any play of the strand of the c cable in the half-cylinder (16) otherwise called contact housing.

Sur la figure 2 d'une prise femelle ,la disposition des éléments est différente que dans le cas d'une prise mâle,car la zône intégrée(7) des fiches (13) constitue toute la fiche elle-même et est occupée par la fiche mâle en situation de branchement.La cavité de contact (8) et la fiche (9) intérieure sont rejetées derrière les fiches femelles (7) ,augmentant la longueur du bloc constitué des parties (11 et 12).Les demi-cylindres (16) vont accueillir les brins du câble dans les mêmes conditions que pour la prise mâle les zones intérieures (7) des fiches mâles le font.De petites pattes d'ancrage dans la matière plastique sont souhaitables.Les faces externes des parties (11 et 12) seront sculpltées de façon à ce que ,comme dans les dispositifs existants l'ensemble fermé puisse être encastré dans un boitier.In FIG. 2 of a female socket, the arrangement of the elements is different than in the case of a male socket, because the integrated zone (7) of the plugs (13) constitutes the entire plug itself and is occupied by the male plug in connection situation.The contact cavity (8) and the internal plug (9) are rejected behind the female plugs (7), increasing the length of the block made up of the parts (11 and 12). 16) will accommodate the strands of the cable under the same conditions as for the male socket the interior areas (7) of the male plugs do so. Small anchoring tabs in the plastic material are desirable. The external faces of the parts (11 and 12) will be sculpted so that, as in existing devices, the closed assembly can be embedded in a box.

Mais,selon cette variante de réalisation de l'invention il faut après avoir éventuelement égalisé l'extrêmité du câble quatre opérations supplémentaires pour effectuer le raccordement:

  • 1)découpage lorgitudinal du câble
  • 2)mise en place des brins du câble dans leur logement
  • 3)fermeture du bloc sur lui-même
  • 4) encastrage du bloc fermé dans un boitier.
However, according to this variant embodiment of the invention, after having possibly equalized the end of the cable, four additional operations are required to make the connection:
  • 1) longitudinal cutting of the cable
  • 2) placement of the cable strands in their housing
  • 3) closing the block on itself
  • 4) embedding the closed block in a box.

Avec la deuxième variante de réalisation,ces quatre opérations sont réduites à une seule.With the second variant, these four operations are reduced to one.

La séparation des brins du câble se fait aussi grâce à une lame mais juste après le découpage ,dans la continuité du geste de fermeture de la prise,en rabattant un bloc de pressage,leur mise en place se fait automatiquement grâce au râcloir du bloc de pressage,aux gouttières de guidage et à la pente de glissement.Quant à l'encastrage du bloc dans un boitier,il n'existe pas puisque l'ensemble de la prise ne forme qu'un seul bloc.The cable strands are also separated by a blade, but just after cutting, in the continuity of the plug closing gesture, by folding down a pressing block, their positioning is done automatically thanks to the scraper of the block of pressing, to the guide gutters and to the slope of sliding. As for the embedding of the block in a box, it does not exist since the whole of the catch forms only one block.

En se reportant à la figure 4 qui représente la partie passive de la prise ,on peut comprendre ce qui se passe en regardant les flèches.Le câble est introduit par derrière et posé dans les gouttières de guidage (21),bien calé sur l'arête de calage (20) jusqu'au bout de la prise où il est introduit dans l'embout de stabilisation ((40),cf fig 5 et 7) non représenté sur la figure 4.Referring to Figure 4 which shows the passive part of the socket, we can understand what is happening by looking at the arrows. The cable is inserted from behind and placed in the guide gutters (21), securely seated on the wedging edge (20) to the end of the socket where it is introduced into the stabilization end piece ((40), see fig 5 and 7) not shown in figure 4.

Après avoir été tranché par la lame (22 cf fig 7) le câble est séparé en deux brins qui glissent le long des pentes de glissement (23) jusqu'au fond du logement de contact (24 cf aussi fig 5) où il est amené par chacune des arêtes inférieures (25) du râcloir (35) cf fig 6 et 7,en même temps qu'il est pénétré par les aiguilles ou épines de contact (4,5) qui font partie intégrante des fiches mâles ou femelles (13) de la prise.La charnière (1) est figurée en pointillés (fig4).La fente de logement de la lame est en (26),la table d'arrêt de fermeture est en (27).La partie descendante (28) des gouttières de guidage s'écarte de l'axe longitudinal central pour aboutir au logement de contact(24) dont l'axe longitudinal est aussi parallèle au plan longitudinal médian des fiches (13 cf aussi fig 5).Restons sur cette dernière figure pour signaler la présence du capot arrière (30),non représenté sur la figure 4. On peut remarquer sur la figure 5 tous les éléments signalés figure 4 mais en vue plongeante plus représentative des dimensions réelles de la prise.After being cut by the blade (22 see fig 7) the cable is separated into two strands which slide along the sliding slopes (23) to the bottom of the contact housing (24 see also fig 5) where it is brought by each of the lower edges (25) of the scraper (35) cf fig 6 and 7, at the same time as it is penetrated by the needles or contact spines (4,5) which are an integral part of the male or female plugs (13) of the socket. The hinge (1) is shown in dotted (fig4) .The blade housing slot is in (26), the closing stop table is in (27). The descending part (28) of the guide gutters deviates from the central longitudinal axis to reach the contact housing (24), the longitudinal axis of which is also parallel to the median longitudinal plane of the plugs (13 see also fig 5). Let us remain on this last figure to indicate the presence of the rear cover (30), not shown in Figure 4 . We can see in Figure 5 all the elements shown in Figure 4 but in a more representative view of the actual dimensions of the socket.

Figure 6 On repère la charnière (1) ,le râcloir (35),la partie supérieure couvrante (33)des gouttières de guidage.La partie plate destinée à venir au contact de la table d'arrêt de fermeture est le marteau d'arrêt de fermeture(37).Le capot antérieur (34) est réhaussé sur sa face inférieure en un réhaussage (36) destiné à laisser passer le câble (non représenté).La lame n'est pas non plus représentée ,mais on peut la voir (figure 9 a,b). Figure 6 We identify the hinge (1), the scraper (35), the covering upper part (33) of the guide gutters. The flat part intended to come into contact with the closing stop table is the stop hammer The front cover (34) is raised on its underside in a raising (36) intended to let the cable pass (not shown). The blade is not shown either, but it can be seen (Figure 9 a, b).

La vue de profil de la figure 7 qui est aussi une vue en transparence complète la vision du dispositif.Le câble (103) opère un trajet avec deux coudes,trajet qui le divise en deux brins (104).Repèrons bien la charnière (1) et la table d'arrêt de fermeture (27) ainsi que le marteau d'arrêt de fermeture (37) qui viennent en contact l'un de l'autre en position fermé. (cf aussi fig 9 a,b).Remarquons aussi le point de point d'ouverture (31) de la fente de logement de la lame (cf aussi fig 4 et 5),fente dont seule une arête supérieure (38) est représentée.L'arête supérieure (32) du râcloir (35) est visible en pointillés La position du bloc de pressage est arrêtée de façon telle que l'on puisse voir que le câble (103) composé de ses brins((104)dont un seul est représenté) a forcément été tranché avant que d'être entraîné dans la descente par la partie supérieure-couvrante(33) des gouttières de guidage et par l'arête (25) du râcloir puisque ces deux dernières parties ont encore leur axe longitudinal parallèle au plan longitudinal médian des fiches et au-dessus du câble quand la lame (22) est déjà en-dessous de l'arête (38) de la fente de logement de la lame où le brin (104) du câble (103) ne peut évidemment pénétrer.L'angle selon lequel est incliné le capot (34) et donc le bloc de pressage lui-même à cet instant est l'angle α qui est l'angle,dans un plan normal au plan longitudinal médian des fiches;ce même angle α est l'angle selon lequel un brin (104) du câble (103) est amené à descendre dans son logement de contact(24).The profile view of FIG. 7 which is also a transparency view completes the vision of the device. The cable (103) operates a path with two elbows, a path which divides it into two strands (104). ) and the closing stop table (27) as well as the closing stop hammer (37) which come into contact with each other in the closed position. (see also fig 9 a, b). We also note the opening point point (31) of the blade housing slot (see also fig 4 and 5), slot of which only one upper edge (38) is shown. .The upper edge (32) of the scraper (35) is visible in dotted lines. The position of the pressing block is stopped so that we can see that the cable (103) composed of its strands ((104) including one only shown) has necessarily been sliced before being driven in the descent by the upper-covering part (33) of the guide gutters and by the edge (25) of the scraper since these last two parts still have their longitudinal axis parallel to the median longitudinal plane of the plugs and above the cable when the blade (22) is already below the edge (38) of the blade housing slot where the strand (104) of the cable (103) Obviously cannot penetrate. The angle at which the cover (34) is tilted and therefore the pressing block itself at this time is the angle α which is the angle, in a plane normal to the median longitudinal plane plugs; this same angle α is the angle at which a strand (104) of the cable (103) is brought down into its contact housing (24).

L'entrée arrière du câble (103) est visible en((43)cf aussi fig 9 c).Cette entrée est de hauteur légèrement inférieure à l'épaisseur du plus petit des câbles admissibles par la prise de façon à ce que le câble soit entré à force sur une petite distance "d" mais soit libre ensuite.L'arête de calage (20) est arrondie en (44) ainsi que le capot arrière (30) en (45) sans oublier les gouttières de guidage (21) en (46) La forme de la lame (22) est visible en pointillé pour ses parties cachées. En son extrêmité antérieure le tranchant et l'arête antérieure (70) de la lame (22) font un angle δ égal à (90°-α).En son extrêmité postérieure la lame est taillée en arc de cercle de rayon r = E/sinρ (où E est l'épaisseur du capot arrière(30)) et ρ l'angle formé par la paroi (47) de la charnière (1) et la face interne (48) du capot arrière (30)).Il est souhaitable que le rayon r soit augmenté d'un ou deux millimètres de jeu comme sur la figure 7 .La hauteur "h" de la lame (22) est égale à: h=l₁ · tgα + D/sin δ + AD + E/2.

Figure imgb0001
The rear cable entry (103) is visible at ((43) see also fig 9 c). This entry is slightly less than the thickness of the smallest of the cables admissible by the socket so that the cable either forced into a small distance "d" but then free. The wedging edge (20) is rounded at (44) as well as the rear cover (30) at (45) without forgetting the guide gutters (21 ) in (46) The shape of the blade (22) is visible in dotted lines for its hidden parts. At its anterior end the cutting edge and the anterior edge (70) of the blade (22) make an angle δ equal to (90 ° -α). In its posterior end the blade is cut into an arc of a circle of radius r = E / sinρ (where E is the thickness of the rear cover (30)) and ρ the angle formed by the wall (47) of the hinge (1) and the internal face (48) of the rear cover (30)). it is desirable that the radius r be increased by one or two millimeters of play as in FIG. 7. The height "h" of the blade (22) is equal to: h = l₁ · tgα + D / sin δ + AD + E / 2.
Figure imgb0001

Enfin pour connaitre la longueur " 1 "de son tranchant,il faut maintenant voir la figure 8 qui explique les relations entre différents angles et distances.Finally to know the length "1" of its cutting edge, we must now see Figure 8 which explains the relationships between different angles and distances.

Partons de AD AD=B′B˝ et B′B=B˝B′/tgβ donc B′B=AD/tgβ

Figure imgb0002
Let's start from AD AD = B′B˝ and B′B = B˝B ′ / tgβ therefore B′B = AD / tgβ
Figure imgb0002

D'autre part:B˝B=B′B/cosβOn the other hand: B˝B = B′B / cosβ

D'autre part encore:AB˝=B˝B′/tgα donc AB˝=AD/tgα de B˝B/AB˝= tgγ on peut tirer l'angle γ et AB car AB˝/cosγ = AB De plus AB + BC = 1 et OA + AB˝ + B′C′ = L et B′C′ = AB + BC - AB˝On the other hand again: AB˝ = B˝B ′ / tgα therefore AB˝ = AD / tgα of B˝B / AB˝ = tgγ we can draw the angle γ and AB because AB˝ / cosγ = AB Furthermore AB + BC = 1 and OA + AB˝ + B′C ′ = L and B′C ′ = AB + BC - AB˝

Si l'on considère que OABC est une ligne brisée qui passe par le centre d'un brin du câble ,on ne peut que remarquer que AB + BC = 1 est la longueur à couper de ce câble et que donc ce doit être la longueur minimum du tranchant de la lame.If we consider that OABC is a broken line which passes through the center of a strand of the cable, we can only notice that AB + BC = 1 is the length to be cut of this cable and therefore it must be the length minimum cutting edge.

Sur les autres dimensions de la prise:
Si l'on connait β que l'on détermine pour que les brins du câble puissent glisser facilement sur les pentes de glissement (23) - soit β ≧ 40° - et que l'on connait BB′ dont la valeur est déterminée par l'écartement standart des fiches d'une prise électrique,on déduit facilement AD et donc la dénivellation du câble .Enfin comme il faut prendre BC suffisemment long pour y faire pénétrer au moins trois contacts qui seront espacés par exemple de 5 mm chacun dans le sens de la longueur -soit BC ≧ 10 mm - ,après avoir donné une valeur à OA en fonction de la longueur totale que l'on veut soi-même donner à la prise ,et après en avoir déduit AB˝,on peut trouver α d'une part γ d'autre part et AB qui permet de calculer la longueur du tranchant de la lame.On peut alors construire la prise.
On the other dimensions of the socket:
If we know β that we determine so that the strands of the cable can slide easily on the sliding slopes (23) - or β ≧ 40 ° - and that we know BB ′ whose value is determined by l standard spacing of the plugs of an electrical outlet, we easily deduce AD and therefore the unevenness of the cable. Finally as it is necessary to take BC long enough to penetrate at least three contacts which will be spaced for example 5 mm each in the direction length - or BC ≧ 10 mm -, after having given a value to OA as a function of the total length that one wants to give oneself to the socket, and after deducing from it AB˝, one can find α on the one hand γ d on the other hand and AB which allows to calculate the length of the cutting edge of the blade. We can then build the grip.

Une vue de la prise en coupes transversales successives va cependant aider à préciser certains détails Figure 9.A view of the taking in successive cross-sections will however help to clarify certain details Figure 9 .

Figure 9 a à gauche la fiche (13) représentée est une fiche mâle,alors qu'à droite il s'agit d'une fiche femelle.Pour conserver la même valeur de l'angle dans les deux cas,il faut jouer sur la distance qui sépare les logements de contact (24) de la surface des fiches (13). La fiche mâle se trouvera donc à une distance du logement de contact plus grande de la différence des rayons des fiches mâles et femelles que ne le sera la fiche femelle. Figure 9 a on the left the plug (13) shown is a male plug, while on the right it is a female plug. To keep the same value of the angle in both cases, you have to play on the distance separating the contact housings (24) from the surface of the plugs (13). The male plug will therefore be at a distance from the contact housing greater than the difference in the radii of the male and female plugs than will be the female plug.

Sur les dessins (a) et (b) on voit que les gouttières de guidage (33) ont un profil qui écrase légèrement les brins (104) du câble.La lame (22) a un profil transversal en " T " pour être bien ancrée dans la matière plastique.On the drawings (a) and (b) we see that the guide gutters (33) have a profile which slightly crushes the strands (104) of the cable. The blade (22) has a transverse profile in "T" to be good anchored in the plastic.

Il faut rechercher sur ce dessin l'arête supérieure (32) du râcloir et les arêtes (25) du râcloir qui sont destinées à entrainer les brins(104) du câble vers leur logement de contact (24). Les deux autres dessins n'appellent pas plus de commentaires.The upper edge (32) of the squeegee and the edges (25) of the squeegee which are intended to drive the strands (104) of the cable towards their contact housing (24) must be sought in this drawing. The other two drawings call for no further comment.

Repèrons maintenant sur la figure 10 ,les éléments constitutifs de la prise selon la troisième variante de réalisation.Now refer to Figure 10 , the components of the socket according to the third embodiment.

Emplacement de la charnière en (1) ,partie arrière du capot (30),marteau d'arrêt de fermeture (37),partie antérieure du capot (34),lame (62),fiches mâles ou femelles (13),poutre de remplissage (50), coins d'écartement ou écarteurs,avant (51),intermédiaire(52),arrière(53) partie arrière conique (54) de la poutre de remplissage (50),fentes de logement des écarteurs,fente avant (71),fente intermédiaire (72),fente arrière (73),évidements latéraux ,avants 81),arrières (83) des des fentes avant et arrière ,fente de logement de la lame (26).La table d'arrêt de fermeture est en (27).Location of the hinge at (1), rear part of the cover (30), closing stop hammer (37), front part of the cover (34), blade (62), male or female plugs (13), beam filling (50), spacers or spacers, front (51), intermediate (52), rear (53) tapered rear portion (54) of the filling beam (50), spacers housing the spacers, front slot ( 71), intermediate slot (72), rear slot (73), lateral recesses, front 81), rear (83) of the front and rear slots, blade housing slot (26). is in (27).

Les épines de contact (4)sont plus visibles sur la figure 11 qui permet de repérer l'orifice arrière (43) d'introduction du câble ,orifice dont les contours (45) sont arrondis et qui comporte un dispositf de coincement léger du câble,ici une bosse (49).The contact spines (4) are more visible in FIG. 11 which makes it possible to locate the rear orifice (43) for introducing the cable, an opening whose contours (45) are rounded and which has a device for lightly clamping the cable , here a bump (49).

On constate aussi que la lame (62) est plus longue en sa partie antérieure que le capot (34),pour trancher complètement le câble à son extêmité antérieure bien que cela ne soit pas obligatoire.Ce câble lors de sa mise en place vient buter au fond de l'emboutde stabilisation (40) dont les contours sont alésés et arrondis pour que ledit câble y pénètre facilement.Le capot étant relativement épais on peut prévoir de biseauter sa partie postérieure (39) ,pour obtenir une épaisseur moindre avant l'amincissement de matière qui permet de constituer la charnière (1) Ayant repéré les épines de contact (4) disposées par exemple comme ici à mi-hauteur d'une épaisseur de brin de câble et les écarteurs (51,52,53) ainsi que leur logement (71,72,73) respectif,situé les évidements latéraux (81,83) correspondant aux logements extrêmes (71,73) et remarquant qu'évidemment la profondeur d'un logement d'écarteur ne peut être inférieure à la hauteur "H" de dépassement du niveau inférieur de la poutre de remplissage (50),on peut se reporter à la figure (12) pour comprendre la relation qui unit différentes dimensions de la prise.We also note that the blade (62) is longer in its front part than the cover (34), to completely cut the cable at its previous end, although this is not compulsory. This cable when it is installed comes up against the bottom of the stabilization end piece (40) whose contours are bored and rounded so that said cable easily penetrates therein. relatively thick one can plan to bevel its posterior part (39), to obtain a lesser thickness before the thinning of material which makes it possible to constitute the hinge (1) Having identified the contact spines (4) arranged for example as here at mid -height of a cable strand thickness and the spacers (51,52,53) as well as their respective housing (71,72,73), located the lateral recesses (81,83) corresponding to the extreme housings (71,73 ) and noting that obviously the depth of a retractor housing cannot be less than the height "H" beyond the lower level of the filling beam (50), we can refer to Figure (12) for understand the relationship between diff erent dimensions of the socket.

Sur cette figure 12 ,pour un écarteur d'épaisseur E′ à son pied,situé à une distande L d'un axe O(représentant la charnière (1)),lui-même situé à une distance P d'un sol X-X′ et devant pénétrer d'une hauteur H ce sol ,la largeur I du logement de l'écarteur doit être au minimum égale à : I = P/tgω- L,où ω est l'angle ayant pour sommet S l'extrêmité la plus éloignée de l'axe O et pour côtés le sol X-X' et le segment S-O distance de la pointe du pied de l'écarteur à l'axe de la charnière.On calcule ω en obtenant son sinus par la relation : P/SO = P/((P+H)² + (E′+L)²) ½ = sin ω .

Figure imgb0003
In this figure 12 , for a thickness spacer E ′ at its base, located at a distance L from an axis O (representing the hinge (1)), itself located at a distance P from a ground XX ′ and having to penetrate from a height H this ground, the width I of the housing of the spacer must be at least equal to: I = P / tgω- L, where ω is the angle having for vertex S the most extreme distant from the axis O and for sides the ground XX 'and the segment SO distance from the tip of the foot of the retractor to the axis of the hinge. We calculate ω by obtaining its sine by the relation: P / SO = P / ((P + H) ² + (E ′ + L) ²) ½ = sin ω.
Figure imgb0003

Les valeurs de L,H et P dépendent des dimensions que l'on veut donner à la prise.L'épaisseur E' doit être la plus faible possible mais doit être assez importante pour que l'écarteur reste rigide lors de la fermeture de la prise.Pour plus de clarté,l'épaisseur E' a été surestimée et les autres dimensions disproportionnées sur ce schéma,l'objectif étant seulement de permettre d'expliquer la relation qui unit tous ces éléments.The values of L, H and P depend on the dimensions to be given to the socket. The thickness E 'must be as small as possible but must be large enough so that the spacer remains rigid when the closure is closed. For greater clarity, the thickness E 'has been overestimated and the other dimensions disproportionate on this diagram, the objective being only to make it possible to explain the relation which unites all these elements.

Sur la figure 13 on peut voir la fente de logement de la lame (26),en transparence,en partie,les fiches (13) avec les épines de contact (4).Juste après l'entrée (43) du câble qui doit être placé par l'utilisateur tout le long de la prise jusqu'à l'embout de stabilisation (40),se trouve le couloir (56).Ce couloir doit avoir une largeur particulière qui est la moyenne de la largeur des câbles les plus courants. Ainsi les plus minces ne se déplaceront que peu et les plus larges seront tassés àforce mais l'élasticité de leur gaine permet de les serrer sans problème.Quand la prise est fermée,un brin du câble fait le trajet fléché passant en son centre;ce sont ces méandres dams les évidements latéraux e.g. (81,83) d'un câble subissant en permanence la pression des écarteurs qui servent de moyen de blocage de chaque brin du câble et donc du câble lui-même.In Figure 13 we can see the blade housing slot (26), in transparency, in part, the plugs (13) with the contact spines (4). Just after the entry (43) of the cable which must be placed by the user all along the socket up to the stabilization end piece (40), there is the corridor (56). This corridor must have a particular width which is the average of the width of the most currents. Thus the thinnest will move only a little and the largest will be compacted with strength but the elasticity of their sheath allows them to be tightened without When the plug is closed, a strand of the cable makes the arrow path passing through its center; it is these meanders in the lateral recesses eg (81,83) of a cable permanently under the pressure of the spacers which serve as a means blocking of each strand of the cable and therefore of the cable itself.

Sur la figure 14 on peut remarquer la partie arrière triangulaire (54) de la poutre de remplissage (50),dont les arêtes inférieures seront avantageusement chanfreinées,et la lame (62) dont les extrêmités avant et arrières dépassent d'un peu la longueur de la poutre de remplisage,pour trancher complètement le câble à l'avant et pour le trancher suffisamment loin de la pointe de la partie arrière (54) de la poutre de remplissage (50) afin que cette partie arrière aie la place de s'enfoncer facilement lors de la fermeture de la prise.In Figure 14 we can notice the triangular rear part (54) of the filling beam (50), whose lower edges will advantageously be chamfered, and the blade (62) whose front and rear ends slightly exceed the length of the filling beam, to cut the cable completely at the front and to cut it far enough from the tip of the rear part (54) of the filling beam (50) so that this rear part has the place of s' easily push in when closing the socket.

La figure 15 montre en vue frontale le profil d'un écarteur extrême,ici avant (51).Plus son cône de pénétration (55) est pointu et plus la fermeture est facile.Cependant sa hauteur H est limitée par celle du boîtier de la prise.Il faut ϑ supérieur à 45° .La tranche des écarteurs sera avantageusement arrondie.D'autre part les écarteurs jouent aussi le rôle de raidisseurs de la lame. Figure 15 shows in front view the profile of an extreme retractor, here before (51). The more its penetration cone (55) and the easier the closure. However its height H is limited by that of the housing of the It must be ϑ greater than 45 °. The edge of the spacers will advantageously be rounded. On the other hand, the spacers also play the role of blade stiffeners.

Cette dernière variante de réalisation qui nous parait être la meilleure ,fonctionne selon le principe de remplissage de l'espace entre les brins du câble,de la partie fixe ,pendant l'écartement,par un volume appartenant à la partie contenant la lame.(partie active).This last variant which seems to us to be the best, works according to the principle of filling the space between the strands of the cable, of the fixed part, during the spacing, with a volume belonging to the part containing the blade. active part).

La description de chacune des trois variantes de réalisation présentées exclut les formes ou reliefs destinés à faciliter la préhension de la prise,de tels ajouts ne changeant rien en ce qui concerne l'invention elle-même n'ont d'ailleurs pas à être décrits ici. Toutefois il faut ménager sur la surface externe de la partie passive un plat qui permette la stabilité de laprise lorsqu'elle est posée sur ce plat,lors de la fermeture de ladite prise.The description of each of the three variant embodiments presented excludes the forms or reliefs intended to facilitate gripping of the grip, such additions changing nothing with regard to the invention itself, moreover, need not be described. here. However, it is necessary to provide on the external surface of the passive part a flat which allows the stability of the socket when it is placed on this flat, when the said plug is closed.

Les figures 17,17,18 attirent l'attention sur les aiguilles ou épines de contact selon les deux dernières variantes de réalisation .Elles ont les mêmes caractéristiques que dans la première variante.La figure 16 montre pour une fiche mâle comment de face et de profil elles sont disposées. Figures 17,17,18 draw attention to the contact needles or thorns according to the last two embodiments. They have the same characteristics as in the first variant. Figure 16 shows for a male plug how to face and profile they are arranged.

On remarque l'angle β et leur emplacement aussi bien dans la vue de face avant de la fiche que dans la vue de côté de la-même fiche. Cet angle β ne concerne toutefois que la deuxième variante.Note the angle β and their location both in the front view of the plug and in the side view of the same plug. This angle β however only concerns the second variant.

La figure 17 montre vu de face comment un brin (104) de câble est pénétré à travers sa gaine (101) et son coeur (102). La logueur des aiguilles ou épines de contact (4,5) est un peu plus importante que dans l'autre variante de réalisation car il faut tenir compte pour arriver à la même pénétration de l'espace entre le brin (104) et la fiche (13).De même que pour la troisième variante. FIG. 17 shows seen from the front how a strand (104) of cable is penetrated through its sheath (101) and its core (102). The logger of the contact needles or thorns (4,5) is a little more important than in the other variant since it is necessary to take into account to arrive at the same penetration of the space between the strand (104) and the plug. (13). As for the third variant.

La figure 18 nous montre surtout la forme des épines de contact dont il faut préciser que la pointe (60) et les arêtes (61) doivent être vives sinon acérées sous peine de difficultés de pénétration. Figure 18 shows us above all the shape of the contact spines, of which it must be specified that the point (60) and the edges (61) must be sharp if not sharp, on pain of penetration difficulties.

Les trois variantes de réalisation comprennent au plus trois pièces métalliques noyées en partie dans un matériau isolant plastique,de préférence du polypropylène ,pour disposer de bonnes charnières.Le moulage par injection des parties plastiques peut se faire en une seule opération.The three alternative embodiments comprise at most three metal parts partially embedded in a plastic insulating material, preferably polypropylene, to have good hinges. The injection molding of the plastic parts can be done in a single operation.
