Abstract

The splice protection sleeve comprises two half-shells (1,2) provided with means for assembling them into a shell, and at least two end flanges (5,6) consisting of sub-flanges assembled by assembling means so as to form an opening for the passage of a cable. The sub-flanges have a tapped portion and a deformable ring interposed between the tapped portion and a frustoconical two-part threaded annulus. The assembling means including two dovetail bars and a wedge joining the two bars together. On the longitudinal free edges of the lower half-shell (1) are snap-fastening teeth (3) which are conjugate with snap-fastening openings (4) of the free longitudinal edges of the upper half shell (2). The half-shell also includes, on the inner face, a cam which extends in the circumferential direction and is followed in this direction by a housing. The flange includes a stub intended to push the cam back before entering the housing.

Manchon de protection d'épissure à protection de ! a garniture d'étanchéité
La présente invention se rapporte aux manchons de protection d'épissure utilisés notamment pour protéger les épissures de câbles électriques ou de télécommunications, tels qu'un câble de fibres optiques.
Protective splice protection sleeve! has gasket
The present invention relates to splice protection sleeves used in particular for protecting the splices of electrical or telecommunications cables, such as a fiber optic cable.

On connaît déjà un manchon de protection d'épissure comprenant deux hémi-coquilles. Les deux hémi-coquilles sont fermées par deux flasques d'extrémité qui définissent une ouverture de passage d'un câble ou de plusieurs câbles. Au moins un flasque d'extrémité comporte une gorge périphérique extérieure dans laquelle est disposée une garniture d'étanchéité qui peut être sous la forme d'un joint solide en caoutchouc ou d'un joint en une matière élastomère souvent dénommée gel. L'hémi-coquille comporte une partie en saillie vers l'intérieur destinée à pénétrer dans la garniture d'étanchéité pour bien comprimer la garniture d'étanchéité.  There is already known a splice protection sleeve comprising two half-shells. The two half-shells are closed by two end flanges which define an opening for the passage of one cable or of several cables. At least one end flange has an outer peripheral groove in which is placed a seal which may be in the form of a solid rubber seal or a seal made of an elastomeric material often called gel. The hemi-shell has an inwardly projecting portion intended to penetrate the seal to compress the seal well.

Le point où l'étanchéité est la plus difficile à assurer est le point où à la fois par les deux hémi-coquilles et le flasque se rejoignent et où la garniture est sollicitée dans deux directions différentes, à savoir suivant la direction périphérique et suivant la direction longitudinale.  The point where sealing is most difficult to ensure is the point where both the two half-shells and the flange meet and where the lining is stressed in two different directions, namely in the peripheral direction and in the longitudinal direction.

L'invention remédie à cet inconvénient par un agencement qui améliore l'étanchéité procurée par la garniture d'étanchéité.  The invention overcomes this drawback by an arrangement which improves the seal provided by the seal.

Suivant l'invention, l'hémi-coquille comporte sur la face intérieure une came qui s'étend dans le sens périphérique et qui est suivie dans ce sens d'un logement et le flasque comporte un tourillon disposé de manière à  According to the invention, the hemi-shell comprises on the inner face a cam which extends in the peripheral direction and which is followed in this direction by a housing and the flange comprises a pin arranged so as to

repousser la came avant de venir dans le logement lorsque l'hémi-coquille est rapprochée du flasque.  push the cam back before coming into the housing when the hemi-shell is close to the flange.

Lors du montage, alors que l'on met par le haut ou par le bas l'hémicoquille sur le flasque tous deux en matière plastique, le tourillon repousse d'abord la came et donc l'hémi-coquille de manière à l'obliger à se déformer et à s'ouvrir, en sorte que l'hémi-coquille vient sur le flasque, et notamment sur la garniture d'étanchéité en élastomère ou en gel, sensiblement perpendiculairement à celle-ci et non plus suivant une direction qui lui était sensiblement tangente. Ce n'est que lorsque le tourillon pénètre dans le logement que l'hémi-coquille revient brusquement à sa position sans avoir au préalable fait subir à la garniture un laminage. Or c'est ce laminage dans la direction périphérique qui créait jusqu'ici une accumulation de matière au point triple, en donnant lieu à des lignes de fuite, en rendant la fermeture plus difficile et en provoquant en d'autres endroits nécessairement une diminution de la quantité de la matière de la garniture d'étanchéité, qui compromettait l'étanchéité. La coopération du tourillon et du logement assure en outre un lien entre l'hémi-coquille et le flasque.  During assembly, while placing the hemico-shell from above or below on the flange, both made of plastic material, the pin first pushes the cam and therefore the semi-shell so as to force it to deform and open, so that the hemi-shell comes on the flange, and in particular on the elastomer or gel seal, substantially perpendicular thereto and no longer in a direction which was substantially tangent. It is only when the pin enters the housing that the hemi-shell suddenly returns to its position without having previously subjected the lining to rolling. Now it is this rolling in the peripheral direction which has hitherto created an accumulation of material at the triple point, giving rise to vanishing lines, making closing more difficult and causing in other places necessarily a reduction in the amount of packing material, which compromised the seal. The cooperation of the pin and the housing also ensures a link between the hemi-shell and the flange.

Au dessin annexé, donné uniquement à titre d'exemple : la figure 1 est une vue en perspective d'un manchon de protection suivant l'invention, alors que les hémi-coquilles sont à distance l'une de l'autre, la figure 2 est une vue partielle en perspective du flasque utilisé suivant l'invention, la figure 3 est une vue en perspective partielle de l'intérieur de l'hémicoquille utilisée suivant l'invention, et la figure 4 est une vue en perspective du manchon de la figure 1, alors que les cames coopèrent avec les tourillons.  In the accompanying drawing, given solely by way of example: FIG. 1 is a perspective view of a protective sleeve according to the invention, while the hemi-shells are at a distance from each other, FIG. 2 is a partial perspective view of the flange used according to the invention, FIG. 3 is a partial perspective view of the interior of the hemicoquilla used according to the invention, and FIG. 4 is a perspective view of the sleeve Figure 1, while the cams cooperate with the pins.

Le manchon de protection d'épissure représenté à la figure 1 comporte deux hémi-coquilles 1 et 2 qui peuvent être fermées le long de leurs bords longitudinaux par des moyens 3 et 4 de fermeture. En outre, les hémicoquilles 1,2 sont fermées à leur extrémité frontale par des flasques 5,6.  The splice protection sleeve shown in Figure 1 comprises two half-shells 1 and 2 which can be closed along their longitudinal edges by means 3 and 4 for closing. In addition, the hemico-shells 1,2 are closed at their front end by flanges 5,6.

A la figure 2, le flasque d'extrémité comporte une gorge 7 périphérique extérieure dans laquelle est disposée une garniture 8 d'étanchéité en matière élastomère.  In Figure 2, the end flange has an outer peripheral groove 7 in which is disposed a gasket 8 of elastomeric material.

A la figure 3, l'hémi-coquille comporte deux nervures 9,10 en saillie vers l'intérieur et destinées à pénétrer dans la garniture 8 d'étanchéité lorsque le manchon de protection est fini de montage. L'hémi-coquille comporte sur la face intérieure respectivement deux cames 11 qui s'étendent dans le sens périphérique et qui sont suivies dans ce sens de logements 12.  In Figure 3, the semi-shell has two ribs 9,10 projecting inwardly and intended to penetrate into the seal 8 when the protective sleeve is finished mounting. The semi-shell comprises on the inner face respectively two cams 11 which extend in the peripheral direction and which are followed in this direction by housings 12.

A la figure 4, le flasque comporte un tourillon 13 destiné à repousser la came 11 avant de venir dans le logement 12.  In FIG. 4, the flange includes a pin 13 intended to push the cam 11 before coming into the housing 12.

Lors du montage, on approche l'hémi-coquille du flasque. Au début les cames 11 et les tourillons 13 viennent respectivement en contact de sorte que l'hémi-coquille 2 se déforme et s'ouvre. Ce n'est que lorsque les tourillons 13 atteignent les logements 12 et y pénètrent que l'hémi-coquille 2 revient à sa position initiale et que les nervures 9,10 viennent en contact avec la garniture 8 et y pénètrent. La garniture 8 n'est ainsi pratiquement pas sollicitée au montage dans une direction autre que normalement à sa surface.  During assembly, we approach the half-shell of the flange. At the start, the cams 11 and the pins 13 come into contact, respectively, so that the semi-shell 2 deforms and opens. It is only when the pins 13 reach the housings 12 and penetrate there that the semi-shell 2 returns to its initial position and that the ribs 9, 10 come into contact with the lining 8 and penetrate there. The lining 8 is thus practically not subjected to assembly in a direction other than normally on its surface.

Les cames 11 sont disposées de part et d'autre des nervures 10 à une distance longitudinale sensiblement égale ou un peu supérieure à l'épaisseur d'un flasque.  The cams 11 are arranged on either side of the ribs 10 at a longitudinal distance substantially equal to or slightly greater than the thickness of a flange.

Chaque came 11 est proche du bord longitudinal de l'hémi-coquille 2. Il en va de même pour l'autre bord longitudinal de l'hémi-coquille 2. Il Y a donc en tout huit cames par hémi-coquille, quatre d'entre elles correspondant à quatre tourillons ménagés sur un même flasque. Deux tourillons sont sur une face du flasque, deux autres sur la face opposée. Il en va de même pour le second flasque. Each cam 11 is close to the longitudinal edge of the hemi-shell 2. The same is true for the other longitudinal edge of the hemi-shell 2. There are therefore altogether eight cams per hemi-shell, four d 'between them corresponding to four pins arranged on the same flange. Two pins are on one side of the flange, two others on the opposite side. The same goes for the second flange.
