Description

Contact électrique et socle de prise comprenant  Electrical contact and socket socket including
un tel contact électrique  such an electrical contact
DOMAINE DE L'INVENTION  FIELD OF THE INVENTION
L'invention concerne un contact électrique comprenant une tresse ou équivalent et un socle de prise équipé d'un tel contact électrique.  The invention relates to an electrical contact comprising a braid or equivalent and a socket base equipped with such an electrical contact.
Par « tresse ou équivalent », on entend tout assemblage de fils tressés ou entrelacés.  "Braid or equivalent" means any assembly of braided or intertwined threads.
ETAT DE LA TECHNIQUE ANTERIEURE  STATE OF THE PRIOR ART
On connaît des contacts électriques comprenant une tresse, une tête de contact et un élément de raccordement montés respectivement sur chaque extrémité de la tresse.  Electrical contacts are known comprising a braid, a contact head and a connecting element mounted respectively on each end of the braid.
Toutefois, lorsqu'un tel contact est soumis à de fortes surintensités, il arrive que la tresse ne résiste pas et fonde, voire se désintègre.  However, when such contact is subjected to strong overcurrent, it happens that the braid does not resist and melts or even disintegrates.
Une solution consiste à utiliser une tresse de plus grande section. Toutefois, une telle solution n'est pas adaptée pour un contact électrique devant présenter un encombrement réduit pour sa mise en œuvre dans un espace confiné. Il existe donc un besoin en ce sens.  One solution is to use a braid of larger section. However, such a solution is not suitable for an electrical contact to have a small footprint for its implementation in a confined space. There is therefore a need in this sense.
PRESENTATION DE L'INVENTION  PRESENTATION OF THE INVENTION
Un mode de réalisation concerne un contact électrique comprenant une tresse ou équivalent s'étendant longitudinalement et présentant une première extrémité et une deuxième extrémité opposée à la première extrémité selon la direction longitudinale, une tête de contact montée sur la première extrémité, un élément de raccordement monté sur la deuxième extrémité, et optionnellement au moins une bague montée sur la tresse ou équivalent entre la tête de contact et l'élément de raccordement, dans lequel la longueur libre X de la tresse ou équivalent (i.e. la longueur libre totale de la tresse ou équivalent) et la somme Y des volumes de matière de la tête de contact, de l'élément de raccordement et de la bague optionnelle vérifient la relation : One embodiment relates to an electrical contact comprising a braid or equivalent extending longitudinally and having a first end and a second end opposite the first end in the longitudinal direction, a contact head mounted on the first end, a connecting member. mounted on the second end, and optionally at least one ring mounted on the braid or equivalent between the contact head and the connecting element, in which the free length X of the braid or equivalent (ie the total free length of the braid or equivalent) and the sum Y of the material volumes of the contact head, the connecting element and the optional ring verify the relation:
où  or
a est un nombre compris entre 10 (dix) et 15 (quinze), b est un nombre compris entre 80 (quatre-vingts) et 110 (cent dix), Y est exprimé en millimètres cubes (mm3), et a is a number between 10 (ten) and 15 (fifteen), b is a number between 80 (eighty) and 110 (one hundred and ten), Y is expressed in cubic millimeters (mm 3 ), and
X est exprimé en millimètres (mm).  X is expressed in millimeters (mm).
On comprend que la tête de contact est la partie du contact qui va permettre de réaliser une liaison électrique avec une broche, par exemple une broche d'un socle de connecteur, tandis que l'élément de raccordement est un élément qui permet de monter le contact sur un fil électrique. On comprend également que la au moins une bague est optionnelle, c'est-à-dire que dans certains modes de réalisation le contact électrique comprend une ou plusieurs bagues tandis que dans d'autres modes de réalisation le contact ne comprend aucune bague.  It is understood that the contact head is the part of the contact that will make it possible to make an electrical connection with a pin, for example a pin of a connector base, while the connecting element is an element which allows to mount the connector. contact on an electric wire. It is also understood that the at least one ring is optional, that is to say that in some embodiments the electrical contact comprises one or more rings while in other embodiments the contact comprises no ring.
Par la suite, et sauf indication contraire, par « la bague », on entend « la au moins une bague optionnelle ». De même, par la suite, et sauf indication contraire, par « tresse » on entend « tresse ou équivalent ».  Subsequently, and unless otherwise indicated, the "ring" means "the at least one optional ring". Similarly, thereafter, and unless otherwise indicated, "braid" means "braid or equivalent".
On comprend que la longueur libre de la tresse est la somme des longueurs selon la direction longitudinale des portions de la tresse qui sont libres, c'est-à-dire qui ne sont recouvertes et en contact avec aucun des éléments parmi la tête de contact, l'élément de raccordement, et la bague. Ainsi, lorsque le contact ne comprend pas de bague, la longueur libre de la tresse est la distance entre la tête de contact et l'élément de raccordement. Lorsque le contact comprend une unique bague, la longueur libre est la somme des longueurs entre la tête de contact et la bague d'une part et entre la bague et l'élément de raccordement d'autre part. Lorsque le contact comprend plusieurs bagues, la longueur libre est la somme des longueurs entre la tête de contact et la bague adjacente, entre les bagues de chaque paire de bagues adjacentes, et entre l'élément de raccordement et la bague adjacente. Bien entendu, dans tout l'exposé et sauf indication contraire, la longueur est mesurée selon la direction longitudinale.  It is understood that the free length of the braid is the sum of the lengths in the longitudinal direction of the portions of the braid which are free, that is to say which are not covered and in contact with any of the elements of the contact head , the connecting element, and the ring. Thus, when the contact does not include a ring, the free length of the braid is the distance between the contact head and the connecting element. When the contact comprises a single ring, the free length is the sum of the lengths between the contact head and the ring on the one hand and between the ring and the connecting element on the other hand. When the contact comprises a plurality of rings, the free length is the sum of the lengths between the contact head and the adjacent ring, between the rings of each pair of adjacent rings, and between the connecting member and the adjacent ring. Of course, throughout the presentation and unless otherwise indicated, the length is measured in the longitudinal direction.
On comprend également que la longueur libre est une longueur mesurée lorsque le contact, et donc la tresse, n'est soumis à aucune contrainte, notamment de traction ou de compression selon la direction longitudinale. Ainsi, la longueur libre est considérée lorsque la tresse n'est soumise à aucune contrainte mécanique, ou, en d'autres termes, lorsque la tresse est « au repos », du point de vue mécanique. Le volume de matière de la tête de contact à prendre en compte est le volume de matière du corps principal de la tête de contact qui est monté sur la tresse. De même, le volume de matière de l'élément de raccordement à prendre en compte est le volume de matière du corps principal de l'élément de raccordement qui est monté sur la tresse. Ainsi, si des éléments additionnels sont montés sur la tête de contact et/ou l'élément de raccordement, comme par exemple des vis ou des circlips, le volume de matière de ces éléments additionnels ne sont pas à prendre en compte. On comprend que la bague ne comprend qu'une seule entité, et forme une seule et même pièce. Le volume de matière à considérer pour la bague est donc le volume de matière de cette pièce. Par conséquent, le volume de matière Y est la somme des volumes de matière du corps principal de la tête de contact, du corps principal de l'élément de raccordement et de la bague optionnelle. Bien entendu, lorsque le contact ne présente pas de bague, le volume de matière Y est uniquement la somme des volumes de matière du corps principal de la tête de contact et du corps principal de l'élément de raccordement. Ainsi, dans ce dernier cas, le volume de matière considéré devant répondre à la relation (1) est réparti entre la tête de contact et l'élément de raccordement. It is also understood that the free length is a length measured when the contact, and therefore the braid, is not subjected to any stress, in particular traction or compression in the longitudinal direction. Thus, the free length is considered when the braid is not subjected to any mechanical stress, or, in other words, when the braid is "at rest", from the mechanical point of view. The volume of material of the contact head to be taken into account is the volume of material of the main body of the contact head which is mounted on the braid. Similarly, the volume of material of the connecting element to be taken into account is the volume of material of the main body of the connecting element which is mounted on the braid. Thus, if additional elements are mounted on the contact head and / or the connecting element, such as screws or circlips, the volume of material of these additional elements are not to be taken into account. It is understood that the ring comprises only one entity, and forms a single piece. The volume of material to consider for the ring is the volume of material of this piece. Therefore, the volume of material Y is the sum of the material volumes of the main body of the contact head, the main body of the connecting element and the optional ring. Of course, when the contact has no ring, the volume of material Y is only the sum of the material volumes of the main body of the contact head and the main body of the connecting element. Thus, in the latter case, the volume of material considered to meet the relationship (1) is distributed between the contact head and the connecting element.
Les inventeurs ont remarqué avec surprise que la résistance de la tresse à la fusion en cas de surintensité est fonction du volume de matière Y en contact avec la tresse. Les inventeurs ont mis en évidence que le volume nécessaire de matière pour éviter toute dégradation de la tresse est fonction de la longueur libre de la tresse. Ainsi, la longueur libre X de la tresse doit être supérieure au volume de matière Y multiplié par un coefficient a, auquel on retranche une constante b ; a étant compris entre 10 et 15 et b étant compris entre 80 et 110. En d'autres termes, pour éviter toute dégradation de la tresse en cas de surintensité, la longueur libre X et le volume de matière Y doivent vérifier la relation (1). Les inventeurs interprètent cette relation (1) comme définissant un volume minimum de matière capable d'absorber et de diffuser tout ou partie de la chaleur générée au sein de la tresse en cas de surintensité, protégeant ainsi la tresse de réchauffement lié à de telles surintensités, grâce à quoi sa dégradation est évitée.  The inventors have surprisingly noticed that the resistance of the braid to fusion in the event of overcurrent is a function of the volume of material Y in contact with the braid. The inventors have demonstrated that the necessary volume of material to prevent any degradation of the braid is a function of the free length of the braid. Thus, the free length X of the braid must be greater than the volume of matter Y multiplied by a coefficient a, to which we deduct a constant b; a being between 10 and 15 and b being between 80 and 110. In other words, to avoid any degradation of the braid in case of overcurrent, the free length X and the volume of material Y must verify the relationship (1 ). The inventors interpret this relation (1) as defining a minimum volume of material capable of absorbing and diffusing all or part of the heat generated within the braid in the event of overcurrent, thereby protecting the heating braid associated with such overcurrents. , thanks to which its degradation is avoided.
Un tel contact présente un encombrement réduit tout en présentant la fiabilité nécessaire en cas de surintensité. Dans certains modes de réalisation, a est compris entre 12 (douze) et 13 (treize) et b est compris entre 90 (quatre-vingt-dix) et 95 (quatre-vingt-quinze). Such contact has a small footprint while having the necessary reliability in case of overcurrent. In some embodiments, a is between 12 (twelve) and 13 (thirteen) and b is between 90 (ninety) and 95 (ninety-five).
Les inventeurs ont remarqué que de tels coefficients permettent d'ajuster plus finement le ratio entre la longueur libre X et le volume de matière Y de manière à assurer une meilleure fiabilité, tout en assurant un encombrement réduit.  The inventors have noticed that such coefficients make it possible to adjust more finely the ratio between the free length X and the volume of material Y so as to ensure better reliability, while ensuring a small footprint.
Dans certains modes de réalisation, b est compris entre 93 (quatre-vingt-treize) et 94 (quatre-vingt-quatorze).  In some embodiments, b is from 93 (ninety-three) to ninety-four (ninety-four).
Les inventeurs ont remarqué que de tels coefficients permettent d'ajuster encore plus finement le ratio entre la longueur libre X et le volume de matière Y de manière à assurer une fiabilité encore meilleure, tout en assurant un encombrement réduit.  The inventors have noticed that such coefficients make it possible to adjust even more finely the ratio between the free length X and the volume of material Y so as to ensure an even better reliability, while ensuring a small footprint.
Dans certains modes de réalisation, la section transversale (Le. perpendiculairement à la direction longitudinale) de la tresse ou équivalent est supérieure ou égale à 2.0 mm2 (deux millimètres carrés). In some embodiments, the cross-section (L 1 perpendicular to the longitudinal direction) of the braid or equivalent is greater than or equal to 2.0 mm 2 (two square millimeters).
Les inventeurs ont constaté que la relation (1) est particulièrement bien adaptée pour les tresses dont la section transversale est supérieure ou égale à 2.0 mm2, qui présentent généralement une fiabilité intrinsèque vis-à-vis des petites surintensités acceptable. Ainsi, l'effet combiné du choix d'une section minimale de la tresse avec la relation (1) permet d'assurer une très bonne fiabilité vis-à-vis des surintensités plus importantes. The inventors have found that the relationship (1) is particularly well suited for braids whose cross section is greater than or equal to 2.0 mm 2 , which generally have an intrinsic reliability vis-à-vis acceptable small overcurrent. Thus, the combined effect of the choice of a minimum section of the braid with relation (1) makes it possible to ensure very good reliability with respect to larger overcurrents.
Dans certains modes de réalisation, la section transversale de la tresse ou équivalent est inférieure ou égale à 3.0 mm2. In some embodiments, the cross section of the braid or equivalent is less than or equal to 3.0 mm 2 .
Les inventeurs ont constaté que la relation (1) est particulièrement bien adaptée pour les tresses dont la section transversale est inférieure ou égale à 3.0 mm2, qui présentent généralement un encombrement acceptable. Ainsi, l'effet combiné du choix d'une section maximale de la tresse avec la relation (1) permet d'assurer un faible encombrement. The inventors have found that the relationship (1) is particularly well suited for braids whose cross section is less than or equal to 3.0 mm 2 , which generally have an acceptable size. Thus, the combined effect of choosing a maximum section of the braid with relation (1) ensures a small footprint.
Dans certains modes de réalisation, la tête de contact comprend une première partie cylindrique creuse recevant la première extrémité de la tresse ou équivalent tandis que l'élément de raccordement comprend une deuxième partie cylindrique creuse recevant la deuxième extrémité de la tresse ou équivalent. On comprend que les parties cylindriques creuses s'étendent longitudinalement autour d'une portion d'extrémité de la tresse, une portion d'extrémité étant une portion de la tresse qui s'étend longitudinalement depuis une extrémité de la tresse. Ainsi, une telle partie cylindrique permet de maximiser la surface de contact entre la tresse et la tête de contact d'une part et entre la tresse et l'élément de raccordement d'autre part, grâce à quoi on améliore l'évacuation de la chaleur interne de la tresse et donc la fiabilité nécessaire en cas de surintensité. In some embodiments, the contact head includes a first hollow cylindrical portion receiving the first end of the braid or the like while the connecting member comprises a second hollow cylindrical portion receiving the second end of the braid or the like. It is understood that the hollow cylindrical portions extend longitudinally around an end portion of the braid, an end portion being a portion of the braid extending longitudinally from one end of the braid. Thus, such a cylindrical portion maximizes the contact surface between the braid and the contact head on the one hand and between the braid and the connecting element on the other hand, whereby the evacuation of the internal heat of the braid and therefore the reliability required in case of overcurrent.
Dans certains modes de réalisation, la première partie cylindrique creuse et/ou la deuxième partie cylindrique creuse et/ou la bague optionnelle est/sont sertie(s) sur la tresse ou équivalent.  In some embodiments, the first hollow cylindrical portion and / or the second hollow cylindrical portion and / or the optional ring is / are crimped onto the braid or the like.
On comprend bien entendu que le sertissage est un sertissage opéré selon une direction perpendiculaire à la direction longitudinale. Le sertissage est facile à mettre en œuvre, et peu coûteux. Il permet également, grâce à la déformation de matière, de réduire localement l'encombrement de la partie sertie tout en assurant un contact fiable entre la tresse et ladite partie sertie.  It is of course understood that crimping is a crimping operation in a direction perpendicular to the longitudinal direction. Crimping is easy to implement, and inexpensive. It also allows, thanks to the deformation of material, locally reduce the size of the crimped portion while ensuring reliable contact between the braid and said crimped portion.
Dans certains modes de réalisation, la tresse ou équivalent, la tête de contact, l'élément de raccordement, et la bague optionnelle sont en cuivre ou en alliage à base de cuivre, ou en argent ou en alliage d'argent.  In some embodiments, the braid or the like, the contact head, the connecting member, and the optional ring are made of copper or copper-based alloy, or silver or silver alloy.
On comprend qu'un alliage à base de cuivre est un alliage comprenant, en masse, au moins 50% de cuivre. De même un alliage à base d'argent est un alliage comprenant, en masse, au moins 50% d'argent. Le cuivre et l'argent présentent de bonnes propriétés de conductivité thermique et électrique, grâce à quoi les parties en contact avec la tresse absorbent et diffusent aisément la chaleur de la tresse en cas de surintensité tout en assurant une bonne conductivité électrique du contact. Ceci permet d'obtenir un contact efficace, d'encombrement réduit et résistant aux surintensités.  It is understood that a copper-based alloy is an alloy comprising, by mass, at least 50% copper. Likewise, a silver-based alloy is an alloy comprising, by weight, at least 50% silver. Copper and silver have good properties of thermal and electrical conductivity, whereby the parts in contact with the braid absorb and easily diffuse the heat of the braid in case of overcurrent while ensuring good electrical conductivity of the contact. This makes it possible to obtain effective contact, reduced size and overcurrent resistance.
Dans certains modes de réalisation, la tête de contact est du type à contact en bout.  In some embodiments, the contact head is of the end contact type.
Un contact du type « en bout » est un contact où la liaison électrique avec un autre contact, par exemple une broche, est assurée par une face d'extrémité distale, en l'occurrence une face d'extrémité distale de la tête de contact, cette face d'extrémité distale étant sensiblement perpendiculaire à la direction longitudinale. Un tel contact est configuré pour coopérer en butée avec une face d'extrémité complémentaire, par exemple une face d'extrémité distale d'une broche, le contact entre ces deux faces étant généralement réalisé avec une certaine pression. Un contact comprenant une tresse est particulièrement bien adapté pour assurer des contacts du type « en bout », la tresse pouvant se déformer selon la direction longitudinale et assurer une bonne qualité de contact électrique. An "end" type contact is a contact where the electrical connection with another contact, for example a pin, is provided by a distal end face, in this case a distal end face of the contact head. , this distal end face being substantially perpendicular to the longitudinal direction. Such a contact is configured to cooperate in abutment with a complementary end face, for example a distal end face of a pin, the contact between these two faces being generally made with a certain pressure. A contact comprising a braid is particularly well adapted to ensure "end" type contacts, the braid being able to deform in the longitudinal direction and ensure a good quality of electrical contact.
Un mode de réalisation concerne également un socle de prise comprenant au moins un contact selon l'un quelconque des modes de réalisation décrits dans le présent exposé.  One embodiment also relates to a socket base comprising at least one contact according to any of the embodiments described herein.
Dans certains modes de réalisation, ledit contact électrique est un contact de terre.  In some embodiments, said electrical contact is a ground contact.
On rappelle qu'un socle de prise forme une partie femelle qui peut appartenir à une prise de courant (où le socle de prise est en général solidaire d'un mur ou équivalent), un prolongateur, ou un connecteur (où le socle de prise fait en générai partie d'une prise mobile) tandis qu'un socle de connecteur forme une partie mâle qui peut appartenir à une prise de courant (ou le socle de connecteur fait en général partie de la fiche), un prolongateur, ou un connecteur (où le socle de connecteur est en général solidaire d'un appareil ou équivalent).  Recall that a socket base forms a female part that can belong to a socket (where the socket is generally integral with a wall or the like), an extension, or a connector (where the socket socket usually made of a mobile socket) while a connector socket forms a male part that may belong to a socket (or the connector socket is usually part of the plug), an extension, or a connector (where the connector socket is usually attached to a device or the like).
On rappelle également que de manière générale, une prise mobile comprend un socle de prise et une poignée ou capotage solidaire dudit socle de prise ; une fiche comprend un socle de connecteur et une poignée ou capotage solidaire dudit socle de connecteur ; un prolongateur est un ensemble comprenant une prise mobile et une fiche ; une prise de courant est un ensemble comprenant un socle de prise et une fiche ; un connecteur est un ensemble comprenant une prise mobile et un socle de connecteur. Bien entendu, la poignée ou capotage peut être intégré(e) au socle de prise ou au socle de connecteur, auquel cas ledit socle de prise ou socle de connecteur forme également une prise mobile ou une fiche.  It is also recalled that generally, a movable socket comprises a socket base and a handle or rollover integral with said socket base; a plug comprises a connector socket and a handle or cowling secured to said connector socket; an extender is an assembly comprising a movable plug and a plug; an outlet is an assembly comprising a socket base and a plug; a connector is an assembly comprising a mobile socket and a connector socket. Of course, the handle or cowling can be integrated (e) the socket base or the connector base, in which case said socket base or connector socket also forms a mobile socket or plug.
Au sein d'un socle de prise, le contact susceptible d'être soumis à la plus forte surintensité est généralement le contact de terre. Il est donc particulièrement intéressant de fournir un socle de prise dont le contact de terre est particulièrement résistant aux surintensités. BREVE DESCRIPTION DES DESSINS In a socket base, the contact likely to be subjected to the strongest overcurrent is usually the earth contact. It is therefore particularly interesting to provide a socket base whose ground contact is particularly resistant to overcurrent. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION DETAILLEE D'EXEMPLES DE REALISATION La figure 1 représente un contact électrique 10 comprenant une tresse 12, une tête de contact 14 et un élément de raccordement 16, le contact 10 s'étendant selon une direction longitudinale Z.  DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS FIG. 1 shows an electrical contact 10 comprising a braid 12, a contact head 14 and a connecting element 16, the contact 10 extending in a longitudinal direction Z.
La tresse 12 s'étend selon la direction longitudinale Z, et présente une première extrémité 12a et une deuxième extrémité 12b opposée à la première extrémité 12a selon la direction longitudinale Z. La tresse 12 est dans cet exemple en cuivre étamé. Dans cet exemple, la section transversale de de la tresse 12 est supérieure ou égale à 2.0 mm2 et inférieure ou égale à 3.0 mm2. Plus précisément, dans cet exemple, la section transversale de la tresse 12 est égale à 2.2 mm2. The braid 12 extends in the longitudinal direction Z, and has a first end 12a and a second end 12b opposite the first end 12a in the longitudinal direction Z. The braid 12 is in this example tinned copper. In this example, the cross section of the braid 12 is greater than or equal to 2.0 mm 2 and less than or equal to 3.0 mm 2 . More specifically, in this example, the cross section of the braid 12 is equal to 2.2 mm 2 .
La tête de contact 14 est montée sur la première extrémité 12a de la tresse 12. Plus particulièrement, dans cet exemple, la tête de contact 14 présente une première partie cylindrique creuse 14a recevant la première extrémité 12a de la tresse 12 et s'étendant longitudinalement sur la première portion d'extrémité 12aa de la tresse 12. Dans cet exemple, la première partie creuse 14a est sertie sur la tresse 12, et plus particulièrement sur la première portion d'extrémité 12aa. Dans cet exemple, la tête de contact 14 est du type à contact en bout et présente une face d'extrémité distale 14b configurée pour assurer un contact en bout. La tête de contact 14 est en alliage à base d'argent, et plus précisément en alliage d'argent et de nickel. Pour améliorer la qualité du contact en bout, la face d'extrémité distale peut être formée par une pastille réalisée dans un autre matériau et rapportée sur le reste de la tête de contact, ou bien par un rivet serti par emmanchement à force. Bien entendu, on considère que la pastille ou le rivet fait intégralement partie du corps principal 14d de la tête de contact 14, et est pris en considération pour le calcul du volume de matière de la tête de contact 14. The contact head 14 is mounted on the first end 12a of the braid 12. More particularly, in this example, the contact head 14 has a first hollow cylindrical portion 14a receiving the first end 12a of the braid 12 and extending longitudinally. on the first end portion 12aa of the braid 12. In this example, the first hollow portion 14a is crimped onto the braid 12, and more particularly on the first end portion 12aa. In this example, the contact head 14 is of the end contact type and has a distal end face 14b configured to provide end contact. The contact head 14 is made of silver-based alloy, and more specifically of silver and nickel alloy. To improve the quality of the end contact, the distal end face may be formed by a pellet made of another material and attached to the rest of the head of contact, or by a rivet crimped by press fitting. Of course, it is considered that the pellet or the rivet is an integral part of the main body 14d of the contact head 14, and is taken into account for calculating the volume of material of the contact head 14.
L'élément de raccordement 16 est monté sur la deuxième extrémité 12b de la tresse 12. Plus particulièrement, dans cet exemple, l'élément de raccordement 16 présente une deuxième partie cylindrique creuse 16a recevant la deuxième extrémité 12b de la tresse 12 et s'étendant longitudinalement sur la première portion d'extrémité 12bb de la tresse 12. Dans cet exemple, la deuxième partie creuse 16a est sertie sur la tresse 12, et plus particulièrement sur la deuxième portion d'extrémité 12bb. L'élément de raccordement 16 comprend également un logement 16b configuré pour recevoir un fil électrique, et des moyens de fixation, dans cet exemple une vis 16c, pour fixer le fil à l'élément de raccordement 16. L'élément de raccordement est en cuivre étamé.  The connecting element 16 is mounted on the second end 12b of the braid 12. More particularly, in this example, the connecting element 16 has a second hollow cylindrical portion 16a receiving the second end 12b of the braid 12 and extending longitudinally on the first end portion 12bb of the braid 12. In this example, the second hollow portion 16a is crimped onto the braid 12, and more particularly on the second end portion 12bb. The connection element 16 also comprises a housing 16b configured to receive an electric wire, and fixing means, in this example a screw 16c, for fixing the wire to the connecting element 16. The connecting element is tinned copper.
Le contact 10 présente dans cet exemple une bague 18 montée sur la tresse 12 par sertissage, cette bague 18 étant disposée entre la tête de contact 14 et l'élément de raccordement 16. De manière générale, la bague est montée à distance de la tête de contact et de l'élément de raccordement (i.e. la bague ne contacte pas la tête de contact ni l'élément de raccordement), mais pas nécessairement. Bien entendu, selon une variante, la bague 18 n'est pas présente. La bague 18 est en cuivre.  The contact 10 has in this example a ring 18 mounted on the braid 12 by crimping, this ring 18 being disposed between the contact head 14 and the connecting member 16. In general, the ring is mounted at a distance from the head contact and the connecting element (ie the ring does not contact the contact head or the connecting element), but not necessarily. Of course, according to one variant, the ring 18 is not present. The ring 18 is made of copper.
Dans cet exemple le contact 10 comprend un ressort à compression 20 qui permet de générer une pression de contact sur la tête de contact 14 lorsque la tête de contact est en butée contre un élément complémentaire afin d'assurer un contact en bout de bonne qualité. Le ressort 10 coopère en butée d'une part avec un épaulement 16d de l'élément de contact 16 et d'autre part avec un circlips 14c de la tête de contact 14.  In this example, the contact 10 comprises a compression spring 20 which makes it possible to generate a contact pressure on the contact head 14 when the contact head is in abutment against a complementary element in order to ensure good quality end contact. The spring 10 cooperates abutting on the one hand with a shoulder 16d of the contact element 16 and on the other hand with a circlip 14c of the contact head 14.
Au repos, dans cet exemple, le ressort 20 n'exerce aucune contrainte sur la tresse 12, qui présente au repos une longueur totale L. Dans cet exemple, la longueur libre X de la tresse est égaie à la somme des longueurs Ll et L2. La longueur Ll est la longueur libre de la tresse entre l'élément de raccordement 16 et la bague 18. La longueur L2 est la longueur libre de la tresse entre la bague 18 et la tête de contact 14. Ainsi, la longueur libre totale X de la tresse 12 est bien la somme des deux longueurs Ll et L2, soit X = Ll + L2. At rest, in this example, the spring 20 exerts no stress on the braid 12, which has at rest a total length L. In this example, the free length X of the braid is equal to the sum of the lengths L1 and L2 . The length L1 is the free length of the braid between the connecting element 16 and the ring 18. The length L2 is the free length of the braid between the ring 18 and the contact head 14. Thus, the total free length X of the braid 12 is indeed the sum of the two lengths L1 and L2, ie X = L1 + L2.
Bien entendu, selon une variante, le contact 10 ne présente pas de bague, de sorte que la longueur libre totale X de la tresse est égale à la longueur L3 entre l'élément de raccordement 16 et la tête de contact 14.  Of course, according to a variant, the contact 10 does not have a ring, so that the total free length X of the braid is equal to the length L3 between the connecting element 16 and the contact head 14.
La somme Y des volumes de matière (i.e. le volume total Y) de la tête de contact 14, de l'élément de raccordement 16 et de la bague 18 correspond à la somme des volumes de matière du corps principal 14d de la tête de contact 14 (i.e. la tête de contact 14 sans le cirdips 14c), du corps principal 16e de l'élément de raccordement 16 (i.e. l'élément de raccordement 16 sans la vis 16c) et de la bague 18. Ces trois éléments étant sertis, et donc déformés plastiquement, on peut considérer que la déformation subie ne modifie par le volume de matière de chacun de ces éléments, de sorte que le volume de matière peut être calculé lorsque ces éléments ne sont pas déformés.  The sum Y of the volumes of material (ie the total volume Y) of the contact head 14, the connecting element 16 and the ring 18 corresponds to the sum of the material volumes of the main body 14d of the contact head. 14 (ie the contact head 14 without the cirdips 14c), the main body 16e of the connecting element 16 (ie the connecting element 16 without the screw 16c) and the ring 18. These three elements being crimped, and therefore plastically deformed, it can be considered that the deformation undergone does not modify the volume of material of each of these elements, so that the volume of material can be calculated when these elements are not deformed.
Dans cet exemple, la longueur libre X et la somme Y des volumes de matière vérifient la relation : In this example, the free length X and the sum Y of the volumes of matter verify the relation:
X étant exprimé en millimètres (mm) tandis que Y est exprimé en millimètres cubes (mm3). X being expressed in millimeters (mm) while Y is expressed in cubic millimeters (mm 3).
Les longueurs libres X et les sommes Y des volumes de matière vérifiant la relation (2) sont représentées sur le graphique de la figure 2, dans la zone du graphique qui n'est pas hachurée.  The free lengths X and the sums Y of the volumes of material satisfying the relation (2) are represented on the graph of FIG. 2, in the zone of the graph which is not hatched.
La figure 3 représente un socle de prise 100 comprenant quatre contacts électriques 10. Chaque contact 10 est relié à un fil électrique 50, bien entendu tous les fils 50 étant distincts, via l'élément de raccordement 16. Chaque contact 10 est disposé dans une alvéole 100a qui forme un espace confiné, et impose donc un encombrement limité de la part du contact 10.  FIG. 3 represents a socket base 100 comprising four electrical contacts 10. Each contact 10 is connected to an electrical wire 50, of course all the wires 50 being distinct, via the connecting element 16. Each contact 10 is arranged in a cell 100a which forms a confined space, and therefore imposes limited space on the part of the contact 10.
Dans la figure 3, la fiche 200 est en approche, les broches 210 étant des broches de type à contact en bout, le contact étant réalisé via leur face d'extrémité distale 210a.  In Figure 3, the plug 200 is in approach, the pins 210 being end-contact type pins, the contact being made via their distal end face 210a.
Sur la figure 4, le socle de prise 100 et la fiche 200 sont enfichés l'un avec l'autre. Les faces extrémités distales 14b des têtes de contact 14 des contacts 10 coopérant en appui avec les faces d'extrémités distales 210a des broches 210, grâce notamment aux ressorts 20. Dans cet exemple, l'ensemble des contacts du socle de prise 100 sont conformes au présent exposé, un des contacts formant un contact de terre. Bien entendu, selon une variante, le socle de fiche 100 comprend un seul contact 10, ou bien plus d'un contact 10. In Figure 4, the socket base 100 and the plug 200 are plugged together. The distal end faces 14b of the contact heads 14 of the contacts 10 cooperating in abutment with the distal end faces 210a of the pins 210, thanks in particular to the springs 20. In this example, all the contacts of the socket base 100 are in accordance with this disclosure, one of the contacts forming a ground contact. Of course, according to one variant, the plug base 100 comprises a single contact 10, or more than one contact 10.
