Abstract

The invention relates to a screw terminal for connecting an electrical conductor, comprising a stirrup clamp constituted by a folded metal strip. The special feature of the invention resides in the fact that the two parallel upper parts A and B are held strongly in contact by means of lateral fastening of the end of the tenon-shaped foot (lug) C fitting into the female part cut out for this purpose in the side of the stirrup clamp. This invention is applicable to all stirrup clamps for connection terminals, wire-clamp terminals, connector cages, stirrup wire clamps for terminals, clamping cages, etc., or those fulfilling the same purpose. The object of this invention is to obtain a desired mechanical screw-clamping strength in all cases, clearly meeting the requirements contained in current standards and which is required by the users.

Description

L'invention est relative à un serre-fils et plus particuliè- rement à un serre-fils à étrier avec vis de serrage, tel que ceux utilisés dane les bornes de reccordement électrique, dites bornes de connexion. The invention relates to a wire clamp and more particularly to a stirrup clamp with clamping screw, such as those used in the electrical connection terminals, called connection terminals.

Ces étriers réalisés actuellement à partir de feuillard métallique replié afin de former une cage fermée, n'offrent pas la résistance souhaitée au niveau du filetage des deux extrémités parallèles en contact, celle-ci tendant à s'écarter l'une de l'au- tre lors de l'effort de vissage, provocant l'inclinaison de la vis. These stirrups currently produced from metal strip folded in order to form a closed cage, do not offer the desired resistance at the level of the threading of the two parallel ends in contact, the latter tending to deviate from one of the - be during the screwing effort, causing the inclination of the screw.

D'autre part la partie extérieur. des deux epaisseurs taraudées n'étant pas solidaire de la partie intérieure, tend sous l'effort de eerrage à provoquer la déformation géométrique de l'étrier.On the other hand the outside part. of the two tapped thicknesses not being integral with the inner part, tends under the stressing force to cause the geometric deformation of the stirrup.

La présente invention a pour but de pallier à ces inconvé nient s en rendant solidaires les deux parties paralléles en contact d'un étrier serre-fils, par l'ancrage latéral de l'extrémité de la bande servant à sa réalisation, dans le flanc du dit étrier. The object of the present invention is to alleviate these drawbacks by making the two parallel parts in contact with a wire clamp, integral by the lateral anchoring of the end of the strip used for its production, in the sidewall. said caliper.

Les caractéristiques et avantages de l'invention reesortiront de la description de mode de réalisation donnés à titre d'exemple et illustrés dans le dessin en perspective figure (1). The characteristics and advantages of the invention will emerge from the description of embodiment given by way of example and illustrated in the perspective drawing in FIG. (1).

La figure (7) est une vue en perspective d'un mode de réalisation de l'étrier serre-file.  Figure (7) is a perspective view of an embodiment of the queue clamp.

L'étrier selon l'invention est formé d'une bande de métal dont les parties extrêmes (a) et (b) viennent se superposer afin de former une double épaisseur. The stirrup according to the invention is formed of a metal strip, the end portions (a) and (b) of which overlap in order to form a double thickness.

La partie (a) est prolongée par une languette (c) en forme de tenon venant s'incruster dans la partie (d) de 11 étrier jusqu'à ne plus former qutune seule épaisseur. The part (a) is extended by a tongue (c) in the shape of a tenon which is embedded in the part (d) of 11 stirrups until they only form a single thickness.

Les formes mâle (c) et femelle (d) découpées dans la bande métallique sont mises en coincidence lors de l'éxécution de l'étrier par repliage. The male (c) and female (d) shapes cut from the metal strip are placed in coincidence during the execution of the stirrup by folding.

Les parties (a) et (b) sont filetées permettant le passage d'une vis. Parts (a) and (b) are threaded allowing the passage of a screw.

La particularité de cette invention peut s'appliquer notamment en construction électrique, à tous les étriers pour bornes de connexion, bornes serre-fils, cages de connecteur, serre-fils d'étrier, cages de serra,oe ets ... ou remplissant le même office. The particularity of this invention can be applied in particular in electrical construction, to all the stirrups for connection terminals, wire clamp terminals, connector cages, stirrup wire clamps, clamp cages, e ets ... or filling the same office.

Lors du serrage de fils conducteurs par l'intermédiaire de la vis ayant pris place, à l'intérieur du filetage, l'effort de réaction entre le fond et les deux parties (a) et (b) taraudées est compensé d'une part par l'appui de l'extrémité de la ianguette (b), dans l'angle intérieur de la languette (a) et d'autre part par l'ancrage du tenon (c) dans la partie (d) prenant appui en (1) et (2) empêchant tout écartement de la partie (a) avec la partie (b)  When tightening conductive wires by means of the screw that has taken place, inside the thread, the reaction force between the bottom and the two tapped parts (a) and (b) is compensated on the one hand by the support of the end of the ianguette (b), in the interior corner of the tongue (a) and on the other hand by the anchoring of the tenon (c) in the part (d) bearing in ( 1) and (2) preventing any separation of part (a) with part (b)

Claims (3)

REVENDICATIONS 1) Serre-file de bornes de connecteurs caractérisé en ce qu'il comporte un systéme d'ancrage réalisé par encaetrement d'une extré- mit (c), dela bande de métal servant a es réalisation dans une partie latérale (d), du dit serre-fils. 1) Connector terminal clamp, characterized in that it includes an anchoring system produced by encasing an end (c), of the metal strip used for making in a lateral part (d), said wire clamp. 2) Serre-fils selon la revendication (1), caractérisé en ce que les deux faces parallèle (a,b), restent fortement en contact. 2) A wire clamp according to claim (1), characterized in that the two parallel faces (a, b) remain strongly in contact. 3) Serre-fil- selon la revendioation (2), caractérisé en ce que les deux faces (a,b), bloquées dans toue les sens, autorieent un taraudage parfait.  3) Wire clamp- according to resellers (2), characterized in that the two faces (a, b), blocked in all directions, allow perfect tapping.
