Les fig. 11 et 12 sont des vues sch6mati- ques illustrant 1e fonctionnement des disposi tifs repr6sent6s. Figs. 11 and 12 are schematic views illustrating the operation of the devices shown.
Le dispositif de serrage des fig. 1 ä 4 com- porte une pike de connexion 1 fix6e rigide- ment sur un support S au moyen d'un Organe de fixation 2. Cette pike de connexion est de forme gen6rale tubulaire et comporte une base d'un diametre <I>a</I> et un col d'un diametre <I>b</I> plus Petit que 1e diametre a. Ce col pr6sente un taraudage dans lequel se visse une pike de serrage 3 de forme generale tubulaire et munie d'un chapeau 4 et dune fente diam6trale 5. La pike de connexion 1 comporte deux ouvertures pratiquees dans sa paroi et situees sur un meme diametre. Chaque ouverture pre- sente une Partie 6 de forme circulaire et une Partie 7 en forme de V. Les deux parois late rales 8 de cette Partie 7 sont en biseau et pre- sentent chacune une arete vive 9. The clamping device of FIGS. 1 to 4 comprises a connection pike 1 fixed rigidly to a support S by means of a fixing member 2. This connection pike is generally tubular in shape and comprises a base with a diameter <I> a </I> and a neck with a diameter <I>b</I> smaller than the diameter a. This neck has a thread into which is screwed a clamping pike 3 of generally tubular shape and provided with a cap 4 and a diametrical slot 5. The connection pike 1 has two openings made in its wall and located on the same diameter. Each opening has a circular Part 6 and a V-shaped Part 7. The two side walls 8 of this Part 7 are bevelled and each has a sharp edge 9.
Comme repr6sent6 schdmatiquement par les fig. 11 et 12, lorsque la piece de serrage 3 est serr6e par vissage, ä la main ou au moyen d'un outil engag6 dans la fente diametrale 5, sur un conducteur 10 muni dune gaine iso- lante 11 et introduit dans l'une des ouvertures 6, 7, elle provoque 1e glissement du conducteur isole 1e long des parois latdrales de la Partie 7 en forme de V de cette ouverture. Au cours de ce glissement, les aretes vives 9 coupent la gaine isolante et entrent en contact avec la Partie m6tallique du conducteur 10. Lorsque ce conducteur est un conducteur souple forme de plusieurs brins, comme represente au dessin (fig. 12), ces brins sont comprimes les uns contre les autres par 1'action combinee de la forme en V des parois de la Partie 7 de 1'ou- verture et de la face frontale inferieure 12 de Forgane de serrage 3. Ainsi, an obtient un bon contact entre ce conducteur et Forgane de con- nexion. En effet, les surfaces m6talliques en contact sont protegees contre Faction oxydante de Fair, car la gaine isolante 11, generalement constituee par une gaine en caoutchouc ou en matiere synthetique, incisee par les aretes vives 9, s'applique de maniere Aanche sur les faces formant ces aretes, interdisant ainsi un khange d'air et 1'entree d'eau, ce qui evite une oxydation du conducteur et des r6actions chi- miques qui sont la cause dune augmentation de la rdsistance de Passage. Ainsi, les qualitds du contact sont conservees dans 1e temps, ce qui presente de tres grands avantages et, en particulier, evite la necessit6 de proceder p6- riodiquement ä un nettoyage ou ä une v6rifica- tion des contacts, comme cela est 1e cas lors- que des dispositifs de connexion electrique de types connus sont utilis6s. As represented schematically by figs. 11 and 12, when the clamping piece 3 is tightened by screwing, by hand or by means of a tool engaged in the diametrical slot 5, on a conductor 10 provided with an insulating sheath 11 and introduced into one of the openings 6, 7, it causes the first insulated conductor to slip along the side walls of the V-shaped Part 7 of this opening. During this sliding, the sharp edges 9 cut the insulating sheath and come into contact with the metallic part of the conductor 10. When this conductor is a flexible conductor formed of several strands, as represented in the drawing (fig. 12), these are compressed against each other by the combined action of the V-shape of the walls of Part 7 of the opening and of the lower front face 12 of the clamping member 3. Thus, a good contact is obtained between this conductor and the connecting device. Indeed, the metal surfaces in contact are protected against the oxidizing action of Fair, because the insulating sheath 11, generally constituted by a rubber or synthetic material sheath, incised by the sharp edges 9, is applied in an Aanche way on the faces forming these edges, thus prohibiting an exchange of air and the entry of water, which avoids oxidation of the conductor and chemical reactions which are the cause of an increase in the resistance of Passage. Thus, the qualities of the contact are preserved over time, which has very great advantages and, in particular, avoids the need to periodically clean or check the contacts, as is the case during - that electrical connection devices of known types are used.
Dans la forme d'execution represent6e par la fig. 5, la pike de connexion 1 est munie de deux ouvertures comportant chacune une Partie oblongue 13 permettant 1'introduction de deux conducteurs 10 isoles, et une Partie 14 en forme de V dont les parois laterales 15 sont arquees et en biseau. Ces faces biseautees 15 forment avec la paroi interieure de la piece 1 des aretes vives 16. In the form of execution represented by FIG. 5, the connection pike 1 is provided with two openings each comprising an oblong part 13 allowing the introduction of two insulated conductors 10, and a V-shaped part 14 whose side walls 15 are arcuate and bevelled. These bevelled faces 15 form, with the inner wall of part 1, sharp edges 16.
Ici encore, lorsque les conducteurs isoles sont introduits dans la Partie oblongue 13 de Fouverture pratiqu6e dans la pike de con- nexion et que Forgane de serrage est serr6 sur ces conducteurs, les aretes vives 16 incisent les gaines de caoutchouc de ces conducteurs et en- trent en contact m6tallique avec les conduc- teurs. Here again, when the insulated conductors are introduced into the oblong part 13 of the opening made in the connection pike and the clamping member is tightened on these conductors, the sharp edges 16 incise the rubber sheaths of these conductors and come into metallic contact with the conductors.
Dans la forme d'ex6cution representee par les fig. 6 ä 8, Forgane de connexion comporte deux ouvertures comportant chacune une Par tie oblongue 17 et deux Parties 18 en forme de V s'ouvrant dans ladite Partie oblongue. Les parois laterales 19 des deux Parties en forme de V sont en biseau et presentent des aretes vives 20. Cette forme d'execution est plus specialement pr6vue pour 1e serrage de deux conducteurs, chacun de ceux-ci Aant comprime par 1'organe de serrage dans Fune des Parties 18 en forme de V des ouvertures pratiquees dans Forgane de connexion. En in- troduisant deux conducteurs dans chacune des deux ouvertures pratiquees dans cet organe de connexion, il est possible de relier electrique- ment entre eux quatre conducteurs. In the form of execution represented by FIGS. 6 to 8, the connection member has two openings each comprising an oblong part 17 and two V-shaped parts 18 opening into said oblong part. The side walls 19 of the two V-shaped parts are bevelled and have sharp edges 20. This form of execution is more specifically provided for the first clamping of two conductors, each of these Aant compressed by the clamping member in one of the V-shaped parts 18 there are openings in the connection organ. By introducing two conductors into each of the two openings made in this connection member, it is possible to electrically connect four conductors to one another.
Dans la forme d'exkution representee par la fig. 9, 1'organe de connexion 1 est tubulaire et presente un filetage externe sur lequel vient se visser 1'organe de serrage 3. L'organe de connexion presente deux ouvertures disposees sur un meme diametre et comportant chacune une Partie circulaire 6 et une Partie 18 en forme de V dont les parois lat6rales 15 sont arquees et biseautees, afin de presenter des aretes vives 16. In the form of execution represented by fig. 9, the connection member 1 is tubular and has an external thread on which the clamping member 3 is screwed. The connection member has two openings arranged on the same diameter and each comprising a circular part 6 and a 18 in the form of a V whose side walls 15 are arched and bevelled, in order to present sharp edges 16.
Dans la forme d'execution representee par la fig. 10, 1'organe de connexion 1 est 6gale- ment tubulaire et muni d'un filetage interne dans lequel se visse un organe de serrage 3 constitu6 par une vis dont 1'extremite comporte une fraisure 21. Les ouvertures destinees. ä re- cevoir 1e conducteur isole sont de forme sein- blable ä celle pratiquee dans 1'organe de con- nexion represente par la fig. 1. In the embodiment represented by FIG. 10, the connecting member 1 is also tubular and provided with an internal thread into which is screwed a clamping member 3 consisting of a screw whose end has a countersink 21. The openings intended. to receive the insulated conductor are of a shape similar to that practiced in the connection member represented by FIG. 1.
Les dispositifs representes permettent de serrer deux conducteurs de diametres tres dif- ferents et d'obtenir un excellent. contaet elec- trique de chacun d'eux avec 1'organe de con- nexion. Cette particularite constitue un tres grand avantage de ces dispositifs, par rapport ä la plupart des dispositifs connus. The devices represented make it possible to clamp two conductors of very different diameters and to obtain an excellent. electrical contact of each of them with the connecting device. This particularity constitutes a very great advantage of these devices, compared with most of the known devices.
