Pince pour la pose d'un conducteur e1ectrique isole La presente Invention a pour objet une pince pour la pose d'un conducteur dlectrique iso16 qui se caractdrise par 1e fait quelle com- porte deux branches formant un V et dont les extremites sont arqu6es de maniere ä epouser un support cylindrique, mais dont les Parties terminales sont recourb6es vers 1'exterieur et par 1e fait que les Bords lat6raux des branches et de la Partie mediane les reliant entre elles sont diriges vers 1'int6rieur de la pince de Sorte que les Bords lat & aux s'impriment respective- ment Jans la surface d'un Support embrassd par lesdites branches, et dans 1'isolation d'un conducteur serre entre ce Support et ladite Par tie mddiane, et retiennent ainsi, dune Part, la pince en Position par rapport audit Support et, d'autre Part, 1e conducteur par rapport ä la pince. Pliers for laying an insulated electrical conductor The subject of the present invention is a pliers for laying an insulated electrical conductor which is characterized by the fact that it comprises two branches forming a V and whose ends are arcuate in a manner to marry a cylindrical support, but whose end parts are curved towards the outside and by the fact that the side edges of the branches and of the middle part connecting them to each other are directed towards the inside of the clamp so that the edges lat & aux are imprinted respectively on the surface of a Support embraced by the said branches, and in the insulation of a conductor tightened between this Support and the said Middle Part, and thus retain, on the one hand, the clamp in Position relative to said Support and, on the other hand, the conductor relative to the clamp.

Le dessin annexe represente, ä titre d'exem- ple, une forme d'execution de la pince, objet de 1'invention. The appended drawing shows, by way of example, one form of execution of the pliers, object of the invention.

La fig. 1 est une vue en perspective. fig. 1 is a perspective view.

La fig. 2 est une vue en coupe ä plus Brande echelle. fig. 2 is a sectional view at larger scale.

La fig. 3 est une vue de Profil, la pince embrassant un Support et serrant 1e conducteur isole. La fig. 4 est une vue de face semblable. Selon 1e dessin annexe, la pince comporte deux branches 1 en forme de V reliees entre elles par une Partie mddiane 2 de forme g6n6- rale cylindrique. Les extrdmites 3 de ces branches sont ar- qu6es afin d'6pouser la forme d'un Support 4 cylindrique. Toutefois, les Parties terminales 5 des branches sont recourb6es vers 1'ext6rieur. Enfin, la Partie m6diane 2; de meme que les branches, et en particulier leurs extremitds ar- qu6es 3 sont bombdes. fig. 3 is a side view, the clamp embracing a Support and gripping the insulated conductor. fig. 4 is a similar front view. According to the appended first drawing, the clamp has two V-shaped branches 1 interconnected by a middle part 2 of generally cylindrical shape. The ends 3 of these branches are arched in order to take the shape of a cylindrical Support 4. However, the terminal parts 5 of the branches are curved outwards. Finally, the Middle Part 2; as well as the branches, and in particular their arcuate ends 3 are curved.

Comme represente par les fig. 3 et 4, la pince est destinee ä embrasser un support cy- lindrique 4. Les Parties arqu6es et bombees 3 de ces branches epousent la forme extdrieure de ce Support et serrent ce Support sous 1'ac- tion dlastique de la Partie mddiane 2. Le conducteur 6 muni de sa gaine isolante 7 est alors serr6 entre cette Partie mddiane 2 et 1e Support 4 embrassd par les branches. Les Bords lat6raux 8 de cette Partie me- diane s'incrustent dans la gaine isolante 7 qui est g6ndralement en caoutchouc ou en matiere plastique synthdtique. En outre, les Bords lat6- raux 9 des branches, et spdcialement les Bords lat6raux des extrdmites arqudes et bomb6es 3 s'incrustent egalement dans la matiere du Sup port 4. Ainsi, la pince est maintenue dans une Position fixe par rapport au Support 4, et 1e conducteur 6, 7 ne peut plus etre deplacd par rapport ä la pince ou au Support. La pince decrite est spdcialement avanta- geuse pour la pose rapide d'un conducteur isole dune installation electrique d'un vdlo- cipede. La pince permet de fixer les conduc- teurs Sur des tringles de freins ou de garde- boue, ou, comme represente au dessin, Sur les gaines 12 des cäbles 10 des freins. Ces gaines peuvent ou non eire recouvertes d'un revete- ment 11 en matiere plastique. As represented by Figs. 3 and 4, the clamp is intended to embrace a cylindrical support 4. The arcuate and domed Parts 3 of these branches match the external shape of this Support and grip this Support under the elastic action of the Middle Part 2. The conductor 6 provided with its insulating sheath 7 is then serr6 between this middle part 2 and the first support 4 embraced by the branches. The side edges 8 of this middle part are embedded in the insulating sheath 7 which is generally made of rubber or synthetic plastic material. In addition, the side edges 9 of the branches, and especially the side edges of the arcuate and domed ends 3 are also embedded in the material of the support 4. Thus, the clip is held in a fixed position relative to the support 4 , and the conductor 6, 7 can no longer be moved relative to the clamp or the support. The clamp described is especially advantageous for the rapid installation of an insulated conductor of an electrical installation of a bicycle. The clamp makes it possible to fix the conductors to the rods of the brakes or mudguards, or, as shown in the drawing, to the sheaths 12 of the cables 10 of the brakes. These sheaths may or may not be covered with a coating 11 of plastic material.

Les essais effectues ont montre que la pince decrite permet de placer tres rapidement et dune maniere absolument süre et propre un conducteur electrique dune installation d'eclai- rage de velocipede. Gräce aux parties termina- les 5 recourbees vers 1'exterieur, une simple poussee b exercee Sur la partie m6diane 2 per- met de provoquer 1e glissement de la pince Sur la surface cylindrique du Support en provo- quant 1'ecartement de ses branches contre 1'ac- tion elastique de la partie m6diane 2. The tests carried out have shown that the clamp described makes it possible to place an electrical conductor of a bicycle lighting installation very quickly and in an absolutely safe and clean manner. Thanks to the end parts 5 curved towards the outside, a simple push b exerted on the middle part 2 makes it possible to cause the clamp to slide on the cylindrical surface of the Support by causing the separation of its branches against the elastic action of the middle part 2.

En examinant 1e dessin, an peut aisement se rendre compte que 1'action elastique de la par- tie 2 provoque non seulement 1e serrage des parties 3 Sur 1e support, mais egalement 1e ser- rage du conducteur 6, 7 entre cette partie me- diane 2 et 1e Support 4. 11 suffit pour cela, dune part, que la distance e entre 1e centre des arcs de cercles formant les extremites arquees 3 et 1e fond de la partie m6diane 2 soit plus petite que la somme du diametre du conduc- teur isole et du demi-diametre du Support et, d'autre part, que 1e rayon a de la partie me- diane 2 soit plus petit que 1e demi-diametre du conducteur isole. Dans une variante, 1e rayon de courbure b des surfaces bombees de la partie m6diane 2 et les extremites 3 pourraient eire remplaces par des Bords lateraux replies vers 1'interieur des pinces. Dans ce cas, la partie m6diane ou les branches, presenteraient, en coupe, la forme d'un U dont les ailes seraient tres petites par rapport ä la partie mediane. En outre, ces ailes pourraient eire paralleles ou ouvertes. By examining the drawing, one can easily realize that the elastic action of the part 2 not only causes the clamping of the parts 3 on the support, but also the clamping of the conductor 6, 7 between this part. diane 2 and the first support 4. It suffices for this, on the one hand, that the distance e between the first center of the arcs of circles forming the arcuate ends 3 and the first bottom of the median part 2 is smaller than the sum of the diameter of the conductor. insulated conductor and the half-diameter of the Support and, on the other hand, that the radius a of the middle part 2 is smaller than the half-diameter of the insulated conductor. In a variant, the first radius of curvature b of the curved surfaces of the middle part 2 and the ends 3 could be replaced by lateral edges folded towards the interior of the grippers. In this case, the middle part or the branches would present, in section, the shape of a U whose wings would be very small compared to the middle part. Furthermore, these wings could be parallel or open.
