Abstract
Description
L'invention est relative à une pince de connexion pour une borne d'appareillage électrique, comprenant :
- au moins deux éléments de contact symétriques destinés à s'embrocher sur ladite borne, et ayant des contacts principaux pour le passage du courant nominal, et des contacts d'arc jouant le rôle de pince éclateur,
- et des moyens élastiques pour assurer une pression de contact sur la borne.
- at least two symmetrical contact elements intended to be plugged onto said terminal, and having main contacts for the passage of the nominal current, and arcing contacts playing the role of spark gap clamp,
- and elastic means for ensuring contact pressure on the terminal.
Les pinces utilisées couramment pour la connexion des fusibles de calibres élevés, notamment pour des intensités de l'ordre de 400 A, sont réalisées à partir d'une tôle de cuivre, découpée et pliée pour former une première pince munie de contacts principaux pour le passage du courant nominal, et une deuxième pince pourvue de contacts d'arc. Les deux pinces sont réunies à une embase commune en forme de U, et la pression des contact est assurée par des ressorts circulaires en forme de circlips agissant sur les branches élastiques de la première pince. Le coût de fabrication de telles pinces est relativement élevé, et l'absorption calorifique due au passage du courant reste très limitée.The clamps commonly used for the connection of high-caliber fuses, especially for intensities of the order of 400 A, are made from a sheet of copper, cut and folded to form a first clamp with main contacts for the passage of the nominal current, and a second clamp provided with arcing contacts. The two clamps are joined to a common U-shaped base, and the contact pressure is ensured by circular springs in the form of circlips acting on the branches elastic of the first clamp. The cost of manufacturing such pliers is relatively high, and the heat absorption due to the passage of the current remains very limited.
L'objet de l'invention consiste à réaliser une pince de connexion pour un appareillage électrique de calibres élevés, bénéficiant d'une dissipation thermique optimum, et d'un coût de fabrication réduit.The object of the invention is to make a connection clamp for an apparatus electric high caliber, with optimum heat dissipation, and cost reduced manufacturing.
La pince de connexion selon l'invention est caractérisée en ce que les deux éléments de contact sont constitués par des barrettes en aluminium, comportant chacune:
- une surface de contact convexe disposée dans la partie médiane interne entre l'embase de fixation à la partie postérieure, et un plot saillant jouant le rôle d'éclateur,
- une chape en matière isolante coiffant la partie antérieure au-dessus du plot pour former un organe d'enclenchement brusque à l'entrée de la pince,
- et des ailettes de dissipation thermique réparties sur la surface externe à l'opposé du plot.
- a convex contact surface disposed in the internal median part between the fixing base to the posterior part, and a protruding stud acting as a spark gap,
- a yoke of insulating material covering the front part above the stud to form a snap engagement member at the entrance of the clamp,
- and heat dissipation fins distributed on the external surface opposite the stud.
Selon un mode de réalisation préférentiel, la face interne de la chape est inclinée par rapport à la direction longitudinale de manière à constituer un convergent avec la chape de l'autre élément de contact. Chaque élément de contact possède une section rectangulaire, et comprend sur la surface externe une rainure située entre les ailettes et l'embase de fixation pour l'ancrage d'un ressort double. La surface de contact est pourvue avantageusement de cannelures pour favoriser le contact électrique avec la borne en forme de couteau. L'un des plots est en cuivre ou en alliage de cuivre, tandis que l'autre plot est réalisé en matière isolante, de manière à reporter la zone d'arc sur le premier plot jouant le rôle de contact d'arc.According to a preferred embodiment, the internal face of the yoke is inclined relative to in the longitudinal direction so as to form a convergent with the yoke of the other contact element. Each contact element has a rectangular section, and includes on the external surface a groove located between the fins and the fixing base for anchoring a double spring. The contact surface is advantageously provided with grooves to promote electrical contact with the knife-shaped terminal. One of the studs are made of copper or a copper alloy, while the other stud is made of material insulating, so as to transfer the arc zone to the first pad playing the role of contact arc.
Selon une caractéristique de l'invention, l'embase de fixation de chaque élément de contact est incurvée par rapport à la plage plane du conducteur de départ pour autoriser des mouvements d'écartement et de rapprochement lors des phases d'embrochage et de débrochage de la borne.According to a characteristic of the invention, the mounting base of each contact element is curved with respect to the flat range of the starting conductor to allow spreading and closing movements during the racking-in and terminal removal.
Selon une autre caractéristique de l'invention, les deux éléments de contact sont dotés de butées agencées sous les surfaces de contact et venant en engagement l'une avec l'autre pour délimiter un premier intervalle transversal entre les plots.According to another characteristic of the invention, the two contact elements are provided with stops arranged under the contact surfaces and coming into engagement with each other to delimit a first transverse interval between the studs.
En fonction du calibre et de l'échauffement toléré, chaque élément de contact est divisé en au moins deux parties adjacentes séparées l'une de l'autre par un deuxième intervalle s'étendant perpendiculairement au premier intervalle de manière à constituer une pince à contacts multiple. Depending on the size and the temperature rise tolerated, each contact element is divided into at least two adjacent parts separated from each other by a second interval extending perpendicular to the first interval so as to constitute a clamp multiple contacts.

En référence aux figures 1 à 4, une pince de connexion 10 d'un fusible 12 à calibres élevés,
est composée de deux éléments de contact 14, 16 allongés, disposés en regard l'un de
l'autre en symétrie par rapport au plan médian longitudinal. Les extrémités postérieures des
deux éléments de contact 14, 16 sont solidarisées à une plage de fixation 18 d'un
conducteur de départ 20.With reference to FIGS. 1 to 4, a
Les éléments de contact 14, 16 présentent des structures identiques constitués par des
barrettes en aluminium, réalisées avantageusement par filage, et faisant l'objet d'un
traitement de surface à base de nickel ou d'argent.The
Chaque élément de contact 14, 16 de section rectangulaire, comporte une surface de contact
22 sensiblement convexe et cannelée, disposée dans la partie médiane interne entre une
butée 24, 25 et un plot 26, 27, ce dernier constituant un éclateur pour l'élément de contact
14 de gauche, et un contre-éclateur pour l'élément de contact 16 de droite. La partie
terminale antérieure au-dessus du plot 16, est coiffée par une chape 28 en matière isolante,
par exemple à base de polyamide, servant d'organe d'enclenchement brusque à l'entrée de
la pince de connexion. Les faces internes des deux chapes 28 sont inclinées par rapport à la
direction longitudinale de manière à constituer un convergent à l'entrée de la pince 10.Each
Les cannelures sur la surface de contact 22 favorisent le contact électrique, et diminuent
l'effort d'insertion et d'extraction de la borne 29 en forme de couteau du fusible 12. La
forme convexe des deux surfaces de contact 22 permettent d'absorber tout défaut
d'alignement de la borne 29 par rapport à la pince 10.The grooves on the
La face latérale externe de chaque élément de contact 14, 16 est dotée d'une série d'ailettes
30 de dissipation thermique, s'étendant à l'opposé du plot 26, 27 entre la chape 28 et une
rainure 32 dans laquelle sont logés bout à bout les brins d'extrémités de deux ressorts 34 de
pression de contact. Chaque ressort a une forme en U prolongée par deux pattes
d'extrémités pliées en équerre. La présence de ce ressort double garantit une répartition
uniforme de la pression de contact de la pince 10 sur la borne 29 en position insérée.The external lateral face of each
La partie postérieure de chaque élément de contact 14, 16 est pourvue d'une embase 36
sensiblement incurvée, et équipée d'un trou taraudé dans lequel est vissée au moins une vis
38 permettant le montage des éléments de contact 14, 16 sur la plage de fixation 18 du
conducteur 20. Un ressort 40 de compression est interposé entre la plage 18 et la tête de
chaque vis 38, de manière à autoriser un léger mouvement d'écartement des éléments de
contact 14, 16 lors de l'entrée ou de la sortie de la borne 29. La venue en engagement des
butées 24, 25 respectives évite le rapprochement des éléments de contact 14, 16 à l'entrée
de la pince 10, et maintient en permanence un intervalle 42 transversal entre les plots 26,
27.The rear part of each
Le plot 26 constituant l'éclateur sur l'élément de contact 14 de gauche, est réalisé en cuivre,
ou en alliage de cuivre au tellure, destiné à résister aux amorces de soudure. L'autre plot 27
constituant le contre-éclateur du deuxième élément de contact 16 est réalisé
avantageusement en matière isolante, par exemple en polyamide, de manière à reporter en
permanence la zone d'arc sur le plot 26, lequel joue le rôle de contact d'arc. Il est clair que
le plot 27 pourrait également être conducteur comme le plot 26.The
Le fonctionnement de la pince de connexion 10 selon les figures 1 à 4 est le suivant:The operation of the
Dans la position débrochée de la pince 10 illustrée aux figures 1 et 4, l'écartement entre les
plots 26, 27 est inférieur à l'épaisseur de la borne 29, et à l'intervalle ménagé entre les
deux surfaces de contact 22. Le ressort double 34 et la venue en engagement des butées 24,
25 maintiennent les deux surfaces de contact 22 sensiblement parallèles entre elles, et
perpendiculaires à la plage de fixation 18. Les plots 26, 27 restent en permanence en saillie
par rapport au convergent des chapes 28.In the withdrawn position of the
En position embrochée ( figure 3), la borne 29 du fusible 12 est insérée entre les deux
surfaces de contact 22, et le ressort double 34 assure une répartition uniforme de la pression
de contact. La réaction mécanique engendrée lors de la phase d'insertion de la borne 29
provoque un léger mouvement d'écartement des éléments de contact 14, 16 suite au
pivotement de sens contraire des embases 36 sur la plage de fixation 18 du conducteur 20.
Le courant du fusible 12 est partagé en deux dans les éléments de contact 14, 16, et l'effet
Joule correspondant est évacué par les ailettes 30 de dissipation thermique. La présence des
chapes 28 isolantes à l'entrée de la pince 10 permet un enclenchement brusque sous tension,
l'arc se produisant exclusivement entre le plot 26 et la borne 29 sans migration sur les
éléments de contact 14, 16 en aluminium.In the plugged-in position (Figure 3),
Lors du débrochage intervenant notamment pour le remplacement d'un fusible défectueux,
le retrait de la borne 29 dans le sens de la flèche F (figure 3) provoque un rapprochement
des surfaces de contact 22 dès que la borne 29 quitte les plots 26, 27. Si la manoeuvre est
opérée sous tension, l'arc s'établit uniquement sur le plot 26 servant de contact d'arc.When racking-out occurs, in particular for the replacement of a defective fuse,
the removal of
Les figures 5 et 6 montrent une pince 100 à contact multiple, dans laquelle chaque élément
de contact 114, 116 est divisé en deux parties 114a, 114b; 116a, 116b adjacentes, séparées
l'une de l'autre par un intervalle 142 s'étendant perpendiculairement à l'intervalle 42. Il est
clair que les éléments de contact 114, 116 pourrait être subdivisé en trois ou quatre parties
égales en fonction du calibre de l'appareillage, et de l'échauffement maximum toléré.FIGS. 5 and 6 show a
