Abstract

The clamp for anchoring and suspension of overhead cables has a body (2) having a provision (3) for clamping the line and a means of attachment to a support. The attachment comprises a short metal cable (4) with one end (4a) fixed to the cable grip (2,3) by moulding the grip onto the cable. Likewise, the hook attachment (5) is moulded onto the other end (4b) of the cable (4). The hook attachment is formed from a hook (5) with a spring safety tongue (6) across the opening, or alternatively a threaded stud. Another variation is a block termination with a mounting flange for bolting or strapping to a support. The line grip is made up of sliding self-locking jaws (3) in the outer housing (2) which is integrally moulded with the cable (4).

Description

L'invention est relative aux pinces d'ancrage ou de suspension pour ligne aérienne. The invention relates to anchoring or suspension clamps for overhead lines.

Les pinces de ce type comprennent un corps muni de moyens de serrage de la ligne et de moyens d'accrochage à un support. Clamps of this type comprise a body provided with means for clamping the line and means for hooking to a support.

Quelle que soit leur forme de réalisation,ces moyens d'accrochage sont,en général, amovibles pour faciliter leur passage dans l'anneau ménagé sur le support.A l'usage,il s' avère que cette amovibilité des moyens d'accrochage est gênante.En effet,lors des manipulations avant pose,les moyens d'accrochage peuvent se séparer du corps, s'égarer et faire défaut au moment de la pose.De même, lors de la pose effectuée en hauteur,l'opérateur peut laisser échapper les moyens d'accrochage et être ainsi obligé d'interrompre son travail pour les remplacer ou aller les chercher au sol.De plus,sous l'action des vibrations ou des contraintes alternées,il arrive que des pinces se décrochent et n'assurent plus l'accrochage de la ligne au support. Whatever their embodiment, these attachment means are, in general, removable to facilitate their passage through the ring formed on the support. In use, it turns out that this removable attachment means Indeed, during handling before installation, the attachment means can separate from the body, get lost and fail at the time of installation. Similarly, during installation carried out at height, the operator can leave escape the attachment means and thus be forced to interrupt his work to replace them or go to look for them on the ground.Moreover, under the action of vibrations or alternating stresses, sometimes clamps come loose and do not provide plus the hooking of the line to the support.

La présente invention a pour but de remédier à cela en fournissant une pince qui,tout en constituant un ensemble imperdable et indécrochable involontairement en exploitation,soit plus simple à mettre en place que les pinces traditionnelles. The object of the present invention is to remedy this by providing a clamp which, while constituting a captive and unbreakable assembly involuntarily in operation, is simpler to put in place than traditional clamps.

A cet effet,les moyens d'accrochage de cette pince comprennent au moins une cablette métallique dont l'une des extrémités est ancrée au corps de pince par surmoulage de ce dernier sur elle. To this end, the attachment means of this clamp comprise at least one metal cable, one of the ends of which is anchored to the clamp body by overmolding the latter on it.

Grâce à cet agencement,la cablette forme un ensemble monolithique avec le corps et ne peut pas en être séparée, même accidentellement. Thanks to this arrangement, the cable forms a monolithic whole with the body and cannot be separated from it, even accidentally.

Dans une forme d'exécution de l'invention,les moyens d'accrochage à un support sont surmoulés sur l'autre extrémité de la cablette. In one embodiment of the invention, the means for hooking to a support are molded onto the other end of the cable.

D'autres caractéristiques et avantages ressortiront de la description qui suit,donnée en référence au dessin schématique annexé représentant quelques formes d'exécution de ces moyens d'accrochage dans le cas de leur application à une pince d'ancrage dont les moyens de serrage de la ligne sont constitués par des mâchoires autoserrantes. Other characteristics and advantages will emerge from the description which follows, given with reference to the appended diagrammatic drawing representing some embodiments of these attachment means in the case of their application to an anchoring clamp whose clamping means of the line consist of self-tightening jaws.

'Dans ce dessin,2 désigne le corps d'une pince d'ancrage et 3 les mâchoires en forme de coins montées coulissantes dans le corps. De façon connue,ces mâchoires 3 sont autoserrantes et rendues imperdables par rapport au corps 2.FIG. 1 is a side elevation view showing a first embodiment of this clamp,
Figures 2 and 3 are partial views showing an embodiment of the attachment means associated with the cable,
FIGS. 4 and 5 are perspective views showing two other embodiments of the means for hooking to a support,
FIG. 6 is a plan view from above showing another embodiment of these attachment means,
'In this drawing, 2 designates the body of an anchoring clamp and 3 the wedge-shaped jaws slidably mounted in the body. In known manner, these jaws 3 are self-tightening and made captive relative to the body 2.

Selon l'invention, les moyens d'accrochage de cette pince d'ancrage à un support comprennent au moins une cablette 4 dont l'extrémité 4a est liée au corps 2 par surmoulage de ce dernier sur elle.Dans la forme d'exécution représentée à la figure 1,les moyens d'accrochage comprennent ,outre la cablette 4,un crochet 5 avec linguet de sécurité 6. Ce crochet est également surmoulé sur l'extrémité 4b de la cablette 4. According to the invention, the means for attaching this anchoring clamp to a support comprise at least one cable 4, the end 4a of which is linked to the body 2 by molding the latter on it. In the embodiment shown in FIG. 1, the hooking means comprise, in addition to the cable 4, a hook 5 with safety catch 6. This hook is also molded on the end 4b of the cable 4.

Grâce à cet agencement,la pince d'ancrage forme un ensemble monolithique avec ses moyens d'accrochage.De ce fait, sen stockage et sa pose sont facilités et sa fonction d'ancrage ou de suspension est constante dans le temps quelles que soient les contraintes et sollicitations auxquelles elle est soumise. Thanks to this arrangement, the anchoring clamp forms a monolithic unit with its attachment means. As a result, its storage and installation are facilitated and its anchoring or suspension function is constant over time whatever the constraints and requests to which it is subjected.

Dans la variante de réalisation représentée aux figures 2 et 3,la cablette 4 est solidaire d'un embout 2 surmoulé sur elle et qui,soit est fileté comme montré en 8 à la figure 2,soit est taraudé comme montré en 9 à la figure 3. In the embodiment shown in Figures 2 and 3, the cable 4 is secured to a tip 2 molded thereon and which is either threaded as shown in 8 in Figure 2, or is tapped as shown in 9 in Figure 3.

hux figures 4 et 5,la cablette 4 est solidaire d'une console 10 composée d'une semelle 10a et d'une partie 10b qui est surmoulée sur l'extrémité 4b de cette cablette 4. hux FIGS. 4 and 5, the cable 4 is integral with a console 10 composed of a sole 10a and a part 10b which is molded onto the end 4b of this cable 4.

La semelle est rapportée sur un support 12 et,notamment, un poteau,soit par des boulons 13 comme montré à la figure 4,soit par des ligatures 14 comme montré à la figure 5.The sole is attached to a support 12 and, in particular, a post, either by bolts 13 as shown in FIG. 4, or by ligatures 14 as shown in FIG. 5.

Dans la forme d'exécution représentée à la figure 6 correspondant à un ancrage double;les corps des deux pinces d'ancrage sont surmoulés sur les eux extrémités 4a 4b d'une meme cablette 4 qui constitue alors,à elle seule, moyen d'accrochage en coopérant avec une console de forme appropriée
Dans toutes ces formes d'exécution,tous les éléments de la pince sont imperdable s les uns par rapport aux autres.In the embodiment represented in FIG. 6 corresponding to a double anchoring; the bodies of the two anchoring clamps are overmolded on the ends 4a 4b of the same cable 4 which then constitutes, in itself alone, means of hanging by cooperating with a console of suitable shape
In all these embodiments, all the elements of the clamp are captive relative to each other.

I1 est évident que l'invention,qui a été décrite cidessus dans le cas de son application à une pince d'ancrage,peut également être appliquée aux pinces de suspension.  It is obvious that the invention, which has been described above in the case of its application to an anchoring clamp, can also be applied to the suspension clamps.
