Abstract
Description
La présente invention a pour objet une pince
isolante pour équipements électriques, comportant deux machoires articulées prolongées chacune par une poignée de préhension, ces poignées et machoires étant
recouvertes d'un revetement électriquement isolant.The present invention relates to a clamp
insulating for electrical equipment, comprising two articulated jaws each extended by a grip handle, these handles and jaws being
covered with an electrically insulating coating.
Depuis pLusieurs années Les équipements et matérieLs électriques sont de pLus en pLus miniaturisés, de sorte que leurs composants sont de plus en plus rapproches. De ce fait, les outils partiellement isolés, en particulier les pinces, utilisées pour les interventions sur ces équipements, provoquent parfois des court-circuits (flashs). For several years Electrical equipment and materials have been miniaturized more and more, so that their components are getting closer and closer. As a result, partially isolated tools, in particular pliers, used for work on this equipment, sometimes cause short-circuits (flashes).
Pour résoudre ce problème, on a proposé des pinces dans lesquelles la complète isolation électrique est obtenue par usinage des surfaces de l'articu
lation qui se chevauchent entre la position de fermeture complète et la position d'ouverture complet de
la pince, et dépit d'un revetement isolant sur ces surfaces usinées. L'usinage est donc exécuté de maniere à permettre l'articulation des surfaces ainsi isoliées.To solve this problem, clamps have been proposed in which complete electrical insulation is obtained by machining the surfaces of the article.
overlapping between the fully closed position and the fully open position of
the clamp, and despite an insulating coating on these machined surfaces. The machining is therefore carried out so as to allow the articulation of the surfaces thus isolated.
Ces outils sont particulièrement onéreux par rapport aux outils habituels partiellement isolés, ce qui limite considérablement leur fabrication sur une écheLLe industrielle. These tools are particularly expensive compared to the usual partially insulated tools, which considerably limits their manufacture on an industrial scale.
L'invention a donc pour but de réaliser une pince totalement revetue d'un isolant électrique agence de telle sorte que son prix de revient ne soit pas notablement supérieur à celui des outils ordinaires, non isolés dans la zone de leur articulation. The invention therefore aims to achieve a plier completely coated with an electrical insulator agency so that its cost is not significantly higher than that of ordinary tools, not isolated in the area of their articulation.
Suivant l'invention, les surfaces metaLli- ques de l'articulation entre les poignées et les machoires sont recouvertes par un manchon souple isolant et élastique rapporté. According to the invention, the metallic surfaces of the joint between the handles and the jaws are covered by a flexible insulating and elastic added sleeve.
Ce manchon peut etre réalisé en une matière
élastique telle que le latex, et est convenablement dimensionne par rapport a la pince de façon à pouvoir serrer élastiquement son articulation en recouvrant totalement les surfaces métalliques de celle-ci qui se chevauchent durant les mouvements d'ouverture et de fermeture des machoires, sans gener ces mouvements grace à son élasticité.This sleeve can be made of a material
elastic such as latex, and is suitably sized relative to the clamp so as to be able to elastically tighten its articulation by completely covering the metal surfaces of the latter which overlap during the opening and closing movements of the jaws, without gener these movements thanks to its elasticity.
Ce manchon peut etre fixé aux bords du revetement isolant encadrant les surfaces de l'articula- tion à isoler, par tout moyen approprié tel que soudage ou collage. This sleeve can be fixed to the edges of the insulating coating framing the surfaces of the joint to be insulated, by any suitable means such as welding or gluing.
L'invention sera maintenant décrite en ré férence au dessin annexé qui en illustre à titre d'exemple non limitatif un mode de réalisation
- La Figure 1 est une vue en perspective d'une pince isolante et de son manchon souple isolant selon l'invention, La pince étant en position d'ouverture partielle;
- la Figure 2 est une vue en élévation lon- gitudinale partielle de la pince fermee et munie de son manchon isolant entourant la zone d'articulation des machoires.The invention will now be described with reference to the accompanying drawing which illustrates by way of nonlimiting example an embodiment
- Figure 1 is a perspective view of an insulating clamp and its flexible insulating sleeve according to the invention, The clamp being in the partially open position;
- Figure 2 is a partial longitudinal elevation view of the clamp closed and provided with its insulating sleeve surrounding the joint area of the jaws.
La pince illustrée au dessin comprend deux mâchoires métalliques 1, 2 prolongées chacune par une poignée manuelle respective 3, 4, ces machoires 1, 2 et les poignées correspondantes 4, 3 présentant une zone d'articulation 5. The clamp illustrated in the drawing comprises two metal jaws 1, 2 each extended by a respective manual handle 3, 4, these jaws 1, 2 and the corresponding handles 4, 3 having an articulation zone 5.
Les poignées 3, 4 sont totalement revetues d'un isolant électrique 6 qui s'étend sur deux cotés opposés de L'articulation 5 et recouvre également chaque machoire 1, 2, à l'exception de leurs deux surfaces métalliques internes la, 2a en regard. L'articulation 5 comporte, entre ces deux surfaces électri quement isolées 7, deux surfaces métalliques dénudées 8, 9, situées sur les deux cOtés opposés de L'articulation 5 entre Les deux surfaces isolées 7. Ces surfaces dénudées 8, 9 sont limitées par les bords 7a, 7b des surfaces isolées 7, et se chevauchent L'une l'au- tre durant les mouvements d'ouverture et de fermeture de la pince. The handles 3, 4 are completely coated with an electrical insulator 6 which extends on two opposite sides of the joint 5 and also covers each jaw 1, 2, with the exception of their two internal metal surfaces la, 2a in look. The joint 5 comprises, between these two electrically insulated surfaces 7, two bare metal surfaces 8, 9, located on the two opposite sides of the joint 5 between the two insulated surfaces 7. These bare surfaces 8, 9 are limited by the edges 7a, 7b of the insulated surfaces 7, and overlap one another during the opening and closing movements of the clamp.
Pour pouvoir isoler électriquement ces surfaces métalliques 8, 9 et ainsi parachever l'isolement de L'ensemble de la pince, celle-ci est compLétée par un manchon souple isolant et éLastique 10, réalisé en une matière élastique convenable telle que le latex, et dimensionné de façon à pouvoir venir s'enfiler sur les machoires 1, 2 fermées (figure 2). Le manchon 10 peut ensuite etre tiré jusqu'à L'articulation 5 de fa çon à recouvrir celle-ci complètement, et à pouvoir etre fixé au revetement isolant 7 ainsi qu'aux bords 7a, 7b de l'isolant autour des surfaces 8, 9. Le manchon souple 10 peut ainsi etre rapporté aux extrémités contiguës des machoires 1, 2 et des poignées 3, 4, par exemple par collage ou soudage a la matière électriquement isolante 6 des surfaces 7. To be able to electrically insulate these metal surfaces 8, 9 and thus complete the isolation of the assembly of the clamp, the latter is completed by a flexible insulating and elastic sleeve 10, made of a suitable elastic material such as latex, and dimensioned so that it can be threaded onto the jaws 1, 2 closed (Figure 2). The sleeve 10 can then be pulled up to the joint 5 so as to cover it completely, and to be able to be fixed to the insulating coating 7 as well as to the edges 7a, 7b of the insulation around the surfaces 8, 9. The flexible sleeve 10 can thus be attached to the contiguous ends of the jaws 1, 2 and of the handles 3, 4, for example by bonding or welding to the electrically insulating material 6 of the surfaces 7.
Grace à son élasticte et au fait qu'il n'adhère pas aux surfaces métalliques 8, 9, le manchon souple 10 autorise sans difficulté l'ouverture maximum de la pince, tout en garantissant son complet isolement -électrique. De cé fait le manchon 10 écarte tout risque de court-circuit consécutif à l'introduction de la pince dans un matériel électrique. Thanks to its elasticity and the fact that it does not adhere to the metal surfaces 8, 9, the flexible sleeve 10 allows without difficulty the maximum opening of the clamp, while guaranteeing its complete electrical isolation. In this way, the sleeve 10 eliminates any risk of short circuit following the introduction of the clamp into electrical equipment.
En variante, le manchon cylindrique 10 peut etre remplacé par un ruban de meme largeur, rapporté autour de l'articulation 5 et fermé sur celle-ci par tous moyens appropriés, connus en soi. Alternatively, the cylindrical sleeve 10 can be replaced by a ribbon of the same width, attached around the joint 5 and closed thereon by any suitable means, known per se.
Bien entendu ce manchon isolant peut etre réalisé en toute matière élastique et électriquement isolante appropriée. Of course, this insulating sleeve can be made of any suitable elastic and electrically insulating material.
Le prix de revient de la pince selon l'invention est à peine supérieur à celui d'une pince classique, dont les surfaces d'articulation ne sont que partiellement isolées. The cost price of the clamp according to the invention is barely higher than that of a conventional clamp, the articulation surfaces of which are only partially insulated.
