Description

Agrafe auto-dénudante de mise à la masse d'un câble
L'invention concerne une agrafe de mise à la masse d'un câble ayant une gaine extérieure enrobant une tresse de masse.Self-stripping clip for grounding a cable
The invention relates to a clip for grounding a cable having an outer sheath encasing a ground braid.

Une telle agrafe est en particulier utilisée lors des opérations de câblage dans les centraux téléphoniques pour mettre à la masse les câbles téléphoniques d'abonnés comprenant successivement un fil électriquement conducteur mono-brin ou multi-brins, une couche isolante entourant le fil conducteur, une tresse de masse entourant la couche isolante et une gaine extérieure isolante. Such a staple is in particular used during wiring operations in telephone exchanges to ground subscriber telephone cables successively comprising an electrically conductive single-strand or multi-strand wire, an insulating layer surrounding the conductive wire, a ground braid surrounding the insulating layer and an insulating outer sheath.

Généralement un telle agrafe est constituée d'une plaque métallique courbée ayant deux ailes se faisant face entre lesquelles est introduite et maintenue une partie du câble. L'agrafe est ensuite posée sur le rebord d'une tôle pour la mise à la masse du câble. Generally such a staple consists of a curved metal plate having two wings facing each other between which is introduced and maintained part of the cable. The clip is then placed on the edge of a sheet to earth the cable.

Actuellement, le câble est dénudé manuellement à l'aide d'une pince ou analogue sur une longueur de 2 à 3 cm pour mettre à nu la tresse de masse du câble. Cette opération requiert une attention toute particulière pour ne pas endommager la tresse de masse. Lorsque le nombre de câbles à mettre à la masse est important, l'opération de dénudation des câbles est longue donc coûteuse. Par ailleurs, certains câbles peuvent être endommagés. Currently, the cable is stripped manually using pliers or the like over a length of 2 to 3 cm to expose the ground braid of the cable. This operation requires special care so as not to damage the ground braid. When the number of cables to be grounded is large, the cable stripping operation is long and therefore expensive. In addition, some cables may be damaged.

Le but de l'invention est de remédier à cet inconvénient en supprimant l'opération de dénudation manuelle. The object of the invention is to remedy this drawback by eliminating the manual stripping operation.

A cet effet, l'invention a pour objet une agrafe de mise à la masse d'un câble ayant une gaine extérieure enrobant une tresse de masse, notamment pour câbles téléphoniques d'abonnés, constituée d'une plaque métallique courbée ayant deux ailes se faisant face entre lesquelles est introduite et maintenue une partie du câble, caractérisée par le fait que chaque aile est pourvue d'au moins une découpe formant un couteau pour couper la gaine afin de mettre à nu ladite tresse de masse lors de la translation du câble entre lesdites ailes et établir un contact électrique avec cette tresse de masse. To this end, the invention relates to a clip for grounding a cable having an outer sheath coating a ground braid, in particular for subscriber telephone cables, consisting of a curved metal plate having two wings facing between which a part of the cable is inserted and maintained, characterized in that each wing is provided with at least one cutout forming a knife for cutting the sheath in order to expose said ground braid during the translation of the cable between said wings and establish electrical contact with this earth braid.

L'invention apporte un gain de temps important dans les opérations de câblage en rassemblant en une seule opération la dénudation du câble et sa mise en place dans l'agrafe. L'agrafe selon l'invention permet en outre de supprimer les risques d'endommagement des câbles. The invention saves significant time in wiring operations by gathering in one operation the stripping of the cable and its installation in the clip. The clip according to the invention also makes it possible to eliminate the risks of damage to the cables.

D'autres caractéristiques et avantages de l'invention apparaîtront dans la description qui suit d'un exemple de réalisation de l'invention faite en référence aux dessins. Other characteristics and advantages of the invention will appear in the following description of an embodiment of the invention made with reference to the drawings.

La figure 1 est une vue en perspective de l'agrafe selon l'invention. Figure 1 is a perspective view of the clip according to the invention.

La figure 2 représente la structure d'une découpe. Figure 2 shows the structure of a cutout.

La figure 3 est une vue en coupe de la figure 1 selon la coupe III-III. Figure 3 is a sectional view of Figure 1 according to section III-III.

La figure 4 représente un câble en place à l'intérieur de l'agrafe posée sur une tôle. Figure 4 shows a cable in place inside the clip placed on a sheet.

Sur la figure 1, une agrafe de mise à la masse d'un câble est constituée d'une plaque métallique 1 courbée pour former deux ailes 2, 3 se faisant face. Le câble 10, visible sur la figure 4, comprend une gaine extérieure isolante 12 enrobant une tresse de masse 13 laquelle entoure des fils électriquement conducteurs 14 isolés par une couche isolante non représentée. In Figure 1, a clip for grounding a cable consists of a metal plate 1 curved to form two wings 2, 3 facing each other. The cable 10, visible in FIG. 4, comprises an insulating outer sheath 12 coating a ground braid 13 which surrounds electrically conductive wires 14 insulated by an insulating layer not shown.

Chaque aile de l'agrafe est pourvue d'au moins une découpe 4 rectangulaire pliée sur un grand bord vers l'intérieur de l'agrafe, la grande arrête de la découpe faisant saillie par rapport à la surface interne de la plaque 1 et étant perpendiculaire à la direction d'introduction du câble dans l'agrafe. Cette découpe pliée forme un couteau pour couper la gaine sur une profondeur adéquate afin de dénuder ledit câble lors de sa translation entre les ailes 2 et 3 et établir un contact électrique avec la tresse de masse du câble mise à nu. La translation du câble entre les ailes s'effectue en tirant celui-ci par une de ses extrémités. Le câble 10 est maintenu à l'intérieur de l'agrafe (figure 4) sous l'effet de la pression des ailes. Each wing of the staple is provided with at least one rectangular cutout 4 folded on a large edge towards the inside of the staple, the large stop of the cutout projecting with respect to the internal surface of the plate 1 and being perpendicular to the direction of introduction of the cable into the clip. This folded cutout forms a knife for cutting the sheath to an adequate depth in order to strip said cable during its translation between the wings 2 and 3 and establish electrical contact with the ground braid of the exposed cable. The cable is translated between the wings by pulling it at one of its ends. The cable 10 is held inside the clip (Figure 4) under the effect of the pressure of the wings.

La découpe d'une aile fait face à la découpe de l'autre aile pour éviter la rotation de l'agrafe lors de la translation du câble à l'intérieur de celle-ci.The cutting of one wing faces the cutting of the other wing to avoid rotation of the clip during the translation of the cable inside the latter.

Comme visible sur la figure 2, une découpe 4 comporte une partie affûtée 5, par exemple sur une demie longueur de l'arrête de la découpe, pour couper la gaine et une partie épaisse 6 prolongeant la partie affûtée en direction de la partie courbée 7 de la plaque 1 pour établir le contact électrique avec la tresse de masse. Cette partie épaisse permet en outre d'avoir un meilleur contact avec la tresse de masse mise à nu sans l'endommager. As can be seen in FIG. 2, a cut 4 has a sharpened part 5, for example over a half length of the cut edge, for cutting the sheath and a thick part 6 extending the sharpened part in the direction of the curved part 7 from plate 1 to establish electrical contact with the earth braid. This thick part also makes it possible to have better contact with the exposed ground braid without damaging it.

Comme visible sur la figure 3, chaque aile peut être pourvue de deux découpes 4, les découpes d'une aile étant disposées en opposition c'est à dire que les parties affûtées des découpes se font face pour dénuder le câble selon ses deux sens de translation à l'intérieur de l'agrafe. As can be seen in FIG. 3, each wing can be provided with two cut-outs 4, the cut-outs of one wing being arranged in opposition, that is to say that the sharp parts of the cut-outs face each other to strip the cable in its two directions of translation inside the clip.

Une des ailes de la plaque, par exemple l'aile 3, est repliée à sa partie terminale 8 vers l'extérieur de l'agrafe pour permettre la fixation de l'agrafe au rebord d'une tôle 11 comme visible sur la figure 4. Cette partie terminale 8 est pourvue d'une découpe formant un ergot élastique 9. Un autre ergot peut également être prévu dans la partie de l'aile 3 en vis-à-vis de la partie terminale 8. One of the wings of the plate, for example the wing 3, is folded at its end portion 8 towards the outside of the staple to allow the fastening of the staple to the edge of a sheet 11 as visible in FIG. 4 This terminal part 8 is provided with a cutout forming an elastic lug 9. Another lug can also be provided in the part of the wing 3 opposite the terminal part 8.

De préférence, la plaque métallique 1 est en acier ressort traité de sorte que les ailes 2, 3 ont une bonne tenue élastique.  Preferably, the metal plate 1 is made of treated spring steel so that the wings 2, 3 have good elastic resistance.
