Description

FIELD OF THE INVENTION The invention relates to the general field of the transport and distribution of data, in particular optical telecommunication, or electrical energy, over aerial wire networks, via overhead conductor cables, and in particular fiber optic cable or electric cables. The invention relates more particularly to suspension systems for overhead conductor cable. BACKGROUND ART Such suspension systems are already known for the mechanical connection and suspension of an overhead conductor cable protected by a sheath of insulating material to any support, for example a pole on which is fixed a bracket. For example, the French patent application FR 2 478 246 describes a suspension system of an overhead power line to a support formed by a console ending in a ring. The suspension system includes an opening shackle that is mounted and closed on the support ring, and a clip that is mounted to and hinged to the shackle. The shackle comprises two distinct parts arranged facing each other so as to form, in the upper part, two notches articulated with respect to each other and configured to cooperate with each other to open / close the shackle on the ring and, in the lower part, a clevis having a reception space. The clamp comprises a head pierced with a through hole and a gutter-shaped base forming a housing for receiving an insulated electrical cable. The head of the clamp is configured to be received in the receiving space of the clevis of the shackle; while the system is provided with 3032070 2 pins that fit into both holes in the yoke and in the through hole of the head which is located opposite the orifices of the yoke, for the articulated mounting of the clamp on the shackle. The clamp is further provided with a latch for holding the cable in its housing.

French patent application FR 2 765 740 also discloses a suspension system for insulated electrical cables to a support formed by a console ending in a ring, this system being quite similar to that described above. In particular, the system includes an opening shackle that is mounted and closed on the support ring, and a clip that is mounted to and hinged to the shackle. The shackle is almost identical to that described above and the clamp is provided with a head similar to that described above, which head is configured to be received in a receiving space of a clevis of the shackle.

The clamp further comprises a laterally open base which forms a cradle, a closing flange pivotally mounted relative to the cradle and configured to close the lateral opening of the base, and a clamping assembly pivotally mounted relative to the cradle. the closure flange and configured to apply the cables introduced into the receiving space 20 formed in the cradle at the bottom of the latter and tighten against this bottom. Optical fiber cable suspension systems are also known to a support formed by a console similar to that described above. For example, a first system is formed only of a clamp similar to that described in the French patent application FR 2,478,246, which clip has a latch adapted to the constitution of a fiber optic cable, generally more fragile than an electric cable. A second known system comprises a metal section having a flat portion for fixing to the support and a bent portion for presenting substantially the shape of a U, a block formed of an elastomeric material which is housed in the space of the U and configured for accommodating the fiber optic cable, and a clamping screw configured to cooperate with two opposite ends of the bent portion and to hold the elastomeric block, and consequently the fiber optic cable, in space The object of the invention is to provide a suspension system of the same kind as those described in the patent applications mentioned above, but with improved mechanical performance, while being particularly simple, convenient and economical. .

In this first state of the system 1, the forces exerted by the cable 2 on the ring 6 of the console 3 and more generally on the post 4 are well below the resistance capabilities of this pole 4; so that the force exerted by the holding member 12 on the anchoring member 10 and on the mechanical connection interface 11 is less than a predetermined threshold value. In the second state (not illustrated) of the system 1, the anchoring member 10 and the holding member 12 are always in their respective closed configuration, while the mechanical connecting interface 11 is in a second configuration in it is always mounted on the anchoring member 10 but and in which it no longer retains (it releases) the retaining member 12, the latter being then no longer mounted on the anchoring member 10 and secured to the post 4. In this second state of the system 1, the forces exerted by the cable 2 on the ring 6 of the console 3 and more generally on the post 4 are close to or even greater than the resistance capabilities of this post 4 ; so that the force exerted by the holding member 12 on the anchoring member 10 and the mechanical connection interface 11 is greater than a predetermined threshold value. If necessary, the mechanical connection interface 11 releases the holding member 12 supporting the cable 2 to avoid damaging the bracket 3 and / or the pole 4. This mechanical connection interface 11 consequently has a limiting function forces exerted on the support, also called fuse. It will be observed, as will be described hereinafter, that the anchoring member 10 also has an open configuration, distinct from its closed configuration, where this anchoring member 10 is not stowed on the ring 6 of the console 3; while the holding member 12 also has an open configuration, distinct from its closed configuration, where a portion of the cable 2 can be introduced and / or removed from the holding member 12.

The first and second parts 20 and 21 each comprise a nose-shaped portion 22 forming, in the closed configuration of the anchoring member 10, a lashing hole 23, and a flange 24 in which an orifice is formed. 25. Each spout-shaped portion 22 is formed of a body 26 and a lateral rib 27 which protrudes from the body 26. The body 26 is provided at a first end of the spout with a first abutment wall 28 and a second abutment wall 36 which are offset relative to one another so as to form a first shoulder 37 at the junction between these first and second abutment walls 28 and 36. The body 26 is further provided at a second end of the nose which is opposite the first end of the nose, a third abutment wall 29 and a fourth abutment wall 30 which are offset relative to each other so that to form a second shoulder 31 at the junction between these third and fourth th abutment walls 29 and 30.

The body 26 is furthermore provided, in the vicinity of the second end of the spout, with a material removal forming an engagement wall 32 connected to the third and fourth abutment walls 29 and 30, which are arranged substantially perpendicularly. at the engagement wall 32, and extending to a fifth abutment wall 33 and a sixth abutment wall 34 which are also formed substantially perpendicular to the engagement wall 32 and thus substantially parallel to the third and fourth abutment walls 29 and 30. The fifth and sixth abutment walls 33 and 34 are offset relative to one another so as to form a third shoulder 35 at the junction between these fifth and sixth walls of the abutment. 33 and 34. The body 26 is further provided with a detent device 38, also called a complementary detent device, or also a second detent device, or a second detent device. complementary detent device, formed by a tooth 39 formed projecting from the engagement wall 32 on the side of the third and fourth abutment walls 29 and 30, and also formed by a recess 40 formed in recess in the wall of engagement 32 on the side of the fifth and sixth abutment walls 33 and 34. The body 26 also has a notch 41 formed in recess in the engagement wall 32 and located between the latching device 38 and an outer edge 43 of the body 26, and a window 42 opening into the notch 41, at the level of the recess 40. The body 26 further comprises a bead 44 formed between the window 42 and the stowing hole 23.

Each flange 24 has an inner face 46 and an outer face 47, opposite to the inner face 46, and a skirt 48 which projects from the outer face 47 and in which the orifice 25 is formed, which opens on each of the inner and outer faces 46 and 47 of the flange 24. The first and second parts 20 and 21 each further comprise a junction portion 49 connecting the spout-shaped portion 22 respectively 24 respective flange.

3032070 14 Each junction portion 49 extends substantially in a circular arc and has, on a first side, a recess groove 50 and, on a second side opposite the first side, a mounting rib 51. In its configuration open, the anchoring member 10 is in two distinct parts, respectively formed by the first and second parts 20 and 21, as illustrated in Figures 3 and 5. To move from its open configuration to its closed configuration, the first and second parts 20 and 21 face each other, with the internal faces 46 of the flanges 24 facing each other and the orifices 25 which are aligned, and with the embedding grooves 50 which are respectively facing the respective embedding ribs 51 for their respective engagement with each other. The spout-shaped portions 22 are urged towards each other under the effect of a rotational movement. The embedding grooves and ribs 50 and 51 respectively cooperate with each other until the teeth 39 of the latching devices 38 cooperate with the respective recesses 40 of these latching devices 38. first and second parts 20 and 21 are thus assembled so that the anchoring member 10 forms only one block, in its closed configuration. In this closed configuration, the first, second, third, fourth, fifth and sixth abutment walls, respectively 28, 36, 29, 30, 33 and 34 of the first and second parts 20 and 21 respectively bear against each other. other; whereas the first, second and third shoulders, respectively 37, 31 and 35 of these first and second parts 20 and 21 respectively face each other; and the engagement walls 32 of these first and second parts 20 and 21 are respectively facing each other. It will be observed that in the closed configuration of the anchoring member 10, the respective indentations 41 of the bodies 26 of the spout-shaped portions 22 face one another and form a through hole 45 of a tool, such as a screwdriver, to detach the teeth 39 and the recesses 40 so as to open the anchoring member 10. It will further be observed that the windows 42 formed in the bodies 26 of the spout-shaped portions 22 are also and in the closed configuration of the anchoring member 10, the inner faces 46 of the flanges are opposite one another a predetermined distance, thus forming a yoke 52 defining a cavity 53 into which the orifices 25 of the flanges 24 open and which is also provided for the suspension of the retaining member 12. The retaining member 12 comprises a base 55 defining a housing 54 and a portion of fixa 56 The base 55 is here formed in two parts, respectively a first element 58 and a second element 59, having a hole 57, which are provided for mounting the holding member 12 on the anchoring member. which are articulated together about a longitudinal axis, with the fixing portion 56 which takes root on the first element 58. The first element 58 is formed of a body 60 having a cradle shape which has a longitudinal opening 62, and two lateral ribs 61 projecting from the body 60. The body 60 has a first end at which the fixing portion 56 is rooted, and a second end, opposite the first end, where a well 63 is formed and a hook 64, which are provided to form a pivot connection hinged to the second element 59. The fixing portion 56 has, on the side of the first end of the body 60 of the first element 58 and remotely hole 57, a complementary latching device 67, also called first complementary latching device, formed of a central window 65 and two side windows 66 located on either side of the central window 65. The hole 57 formed in the fixing portion 56 here has a predetermined diameter.

The second element 59 is formed of a body 68 having a complementary cradle shape designed to close the longitudinal opening 62 of the body 60 of the first element 58; and a lateral rib 69 protruding from the body 68.

The body 68 has, at a first end, a pivot rod 70 configured to be received in the well 63 and fixed to the hook 64 of the first element 58, for the articulation of this pivot rod 70 and thus the second element 59 relative to to the first member 58. The body 68 has, at a second end opposite the first end, a latching device 71, also called the first latching device, formed by a base 72 which project from the opposite side to the side where the lateral rib 69 extends, a central block 73 and two lateral protuberances 74. Each of the lateral protuberances 74 is provided at a distal end of the base 72 with a detent notch 75. The retaining member 12 further comprises an open sleeve 76 made of elastomeric material and configured to be introduced into the housing 54 formed by the base 55 of the holding member 12. This open sleeve 76 is configured to receive r a portion of the optical fiber cable 2 and tighten it without damaging it. For this purpose, the open sleeve 76 has a first block 77 and a second block 78 connected to the first block 77 by a hinged bridge 79, which is located opposite a slot 80 which extends along the entire open sleeve 76 which is provided for insertion of the optical fiber cable 2 into a reception space 81 defined between the first and second blocks 77 and 78. Each of the first and second blocks 77 and 78 has a longitudinal recess 83 which is closed, on the side of the reception space 81, by a respective deformable inner wall 82. Each of the deformable internal walls 82 is thin enough to be deformed, for example by the fiber optic cable 2, in the manner of a web, and thus to enlarge the reception space 81. The enlargement of the space Home 81 is possible thanks to the recesses 83 which see their volume 3032070 respectively decrease, the respective deformable inner wall 82 encroaching into these recesses 83 (Figure 2). The open sleeve 76 further includes, at a first end, a first abutment rib 84 formed protruding from the first block 77, away from the accommodating space 81; and at a second end opposite the first end, a second abutment rib 85 formed projecting from the second block 78, also opposite the reception space 81. The open sleeve 76 is introduced into the housing 54 of the base 55, with its slot 80 which is at the longitudinal opening 62 of the base 55, with its first abutment rib 84 which bears against a lateral edge of the body 60 of the first element 58, and with its second abutment rib 85 which abuts against a lateral edge of the body 68 of the second element 59. The open sleeve 76 is thus prevented from moving longitudinally relative to the base 55. In its open configuration, the holding member 12 has its second element 59 which is at a distance from its first element 58, at least at the level of the fixing portion 56. A portion of the optical fiber cable 2 can then be introduced into the reception space 81 by passing through the opening 20 l longitudinal direction 62 and through the slot 80. To move from its open configuration to its closed configuration, the second element 59 is hinged and close to the first element 58 until the central block 73 is received in the central window 65 and the two lateral protuberances 74 are received in the respective side windows 66, with the detent notches 75 which are hung on the respective contours of these side windows 66 (FIGS. 2 and 6). It will be observed that conversely, to pass from its closed configuration to its open configuration, a user must solicit the lateral protuberances 74 so as to disengage the latching notches 75 of the respective contours 30 of the side windows 66 so as to pull out the central block 73 and the two lateral protuberances 74 respectively of the central window 65 and the side windows 66 by pivoting the second element 59 relative to the first element 58. The system 1 further comprises a socket 13 configured to be introduced into the hole 57 of the fixing portion 56 of the holding member 12.

As illustrated in Figures 2, 3 and 6, this sleeve 13 has an inner face which here has two chamfered walls 86, or ramp, and a substantially flat end wall 87 connecting the two chamfered walls 86; so as to form a conical inner face. The mechanical connection interface 11 is at least partially elastic and deformable and is configured, as mentioned above, to hold the holding member 12 with the anchoring member 10 in its first configuration and to release the holding member 12 of the anchoring member 10 in its second configuration. For this purpose, this mechanical connection interface 11 comprises two rods 88, each made of a composite synthetic material having elastic properties predetermined to be each at least partially deformable, and which extend facing each other and substantially in parallel. The rods 88 also have a predetermined length.

Each rod 88 is provided with a first end connected to a first bridge 89 and a second end, opposite the first end, which is connected to a second bridge 90. The second bridge 90 is located opposite the first bridge 89, and substantially in parallel.

The mechanical connection interface 11 further comprises two support pieces 91 facing each other and each mounted on a respective rod 88. The rods 88 and the first and second bridges 89 and 90 thus form a mechanical connection interface 11 having the shape of a deformable parallelepipedic structure 30 configured to allow the approximation and the spacing of the support pieces 91 relative to each other. the other for respectively 3032070 19 provide the first and second configurations of the mechanical connection interface 11. Each support piece 91 here comprises a positioning shoe 92 mechanically secured on a respective rod 88, a drum 93 which is 5 respective positioning shoe 92 and a support ball 94 disposed at a distal end of the respective barrel 93 and at least partially inserted into the respective barrel 93. The positioning shoes 92 are each positioned on a respective rod 88, at a first predetermined distance from the first bridge 89 10 and at a second predetermined distance from the second bridge 90. It should be noted that the first predetermined distance may be substantially equal to, or less than, or greater than the second predetermined distance. The mechanical linkage interface 11 is configured to naturally bias the balls 94 to approach one another. The mechanical connection interface 11 is furthermore configured here so that the restoring force which is exerted by the rods 88 and which makes it possible to urge the support pieces 91 and consequently the balls 94, is determined as a function of least one parameter among the material of the rods 88, including its elastic and / or deformation properties and consequently the flexibility of the rods 88, the length of the rods, the location of the positioning shoes 92 on the rods 88 and therefore the first and second distances between these shoes 92 and respectively the first and second bridges 89 and 90, the section of the rods 88 (including the diameter in the case of cylindrical rods), or the shape of the balls 94. This restoring force can be determined by function of one or more of the parameters mentioned above. It will be observed that in FIGS. 8 and 9, the support pieces 91 are in a rest position where the balls 94 facing each other are separated from each other by a predetermined (natural) distance. The rods 88 are here also in a rest position, or natural; whereas in FIG. 2, the support pieces 91 are in a first position in the first configuration of the mechanical connection interface 11.

The return force which is exerted by the rods 88 and which makes it possible to urge the support pieces 91, is of course determined according to the predetermined threshold value which determines the passage from the first configuration to the second configuration of the Mechanical Link Interface 11. The method of securing the optical fiber cable 2 to the pole 4 will now be described through the suspension system 1 described above. The anchoring member 10, initially in its open configuration, 10 is passed in closed configuration where its spout-shaped portions 22 are partially introduced into the ring 6 of the console 3 which is mounted on the pole 4, and closed again. by snapping into the recess defined by this ring 6, as described above. The anchoring member 10 is thus secured to the post 4 via the bracket 3 15 and forms a yoke 52 for fixing the mechanical connection interface 11 and the holding member 12. The mechanical connection interface 11 is mounted tightly on the anchoring member 10, with the drums 93 supporting parts 91 which are biased and at least partially introduced into the orifices 25 through the skirts 48 and 20 with the balls 94 which open into the cavity 53 of the yoke 52. The positioning shoes 92 are also stressed and come in their immediate vicinity, even in contact, the free edges of the skirts 48. The holding member 12 is in its open configuration and, as mentioned above, the portion of the optical fiber cable 2 is introduced into the reception space 81 of the open sleeve 76 via the longitudinal opening 62 and the slot 80. The holding member 12 has passed into its closed configuration by articulating the first and second elements 58 and 59 between them, up to 30 snap the lateral protuberances 74 provided with latching notches 75 in the side windows 66 respectively formed in the fixing portion 56.

The optical fiber cable 2 is then sandwiched between the first and second blocks 77 and 78, whose respective inner walls 82 are deformed inside the recesses 83 to enlarge the reception space 81; so as to sufficiently hold the cable 2 in the holding member 12 which supports it, without damaging the cable 2. The holding member 12 supporting the cable 2 is then mounted and held on the anchoring member 10 by Via the mechanical connection interface 11. The fixing portion 56 of the holding member 12 is inserted into the cavity 53 of the yoke 52 of the anchoring member, with the orifices 25 and the hole 57 who communicate with each other. The introduction of the fixing portion 56 is forced to separate the balls 94 from one another; the latter approaching automatically once the hole 57 aligned with the orifices 25.

The balls 94 then each come to be housed at least partially in the bushing 13 which is in the hole 57 of the fixing portion 56, until it bears against the chamfered walls 86 of this bushing 13, whose internal face is substantially conical. The mechanical connection interface 11 is then in its first configuration where it retains the holding member 12 and where its balls 94 are in their first position in which they are loaded and are at a distance one of the other at least equal and rather greater than the distance where they are in their rest position. When the forces by the cable 2 on the ring 6 of the console 3 and more generally on the post 4 are such that the force exerted by the holding member 12 on the anchoring member 10 and on the interface the mechanical connection 11 is greater than the predetermined threshold value, then the chamfered walls 86 of the bushing 13 each urge a ball 94 against the force exerted by the respective rods 88, thus deforming the rods 88 which are flexible, until the fixing portion 56 leaves the cavity 53 of the yoke 52 and thus the holding member 12 is released from the anchoring member by the mechanical connection interface 11.

3032070 22 This frees the fiber optic cable 2 to not damage the console 3 and / or the post 4 on which this cable 2 is stowed. If necessary, the holding member 12 is released with the portion of the cable 2 which remains inserted in the latter.

It will be appreciated that the shape of the bushing 13 may also be a parameter taken into account in the determination of the restoring force which is exerted by the rods 88 and which makes it possible to urge the support pieces 91 and consequently the balls 94 FIG. 10 illustrates a suspension system whose elements 10 are quite similar to those of the system illustrated in particular in FIGS. 1 to 3. In general, the same reference numerals of the number 100 have been used for similar elements. The suspension system 101 comprises an anchoring member 110 and a holding member 112 which are identical to those of the system 1, described above with particular reference to FIGS. 3 to 7. The mechanical connection interface 111 of the system 101 differs from the mechanical connection interface 11 of the system 1, described above with reference in particular to Figures 3, 8 and 9.

The mechanical connection interface 111 is here formed of a partially circular spring piece 188, of oblong shape, and made of a metallic material having predetermined elastic properties. The spring piece 188 is provided with two free ends 195 and two bearing pieces formed here by balls 194, each of which is formed on one of the two free ends 195 respectively and located opposite one another. The spring piece 188 is configured so that the balls 194 can each be housed at least partially in the sleeve 113 which is in the hole of the fixing portion 156, until it bears against the chamfered walls 186 of FIG. this socket 113, whose inner face is substantially conical.

The spring member 188 is further configured to permit the balls 194 to be brought together and spaced relative to each other to respectively provide the first and second configurations of the mechanical link interface 111, in a manner that similar to that described above with respect to the mechanical connection interface 11. It should be noted that the restoring force which is here exerted by the spring piece 188 and which makes it possible to urge the balls 194 can be determined as a function of at least one parameter among the shape of the bushing 113, the closing edge of the workpiece spring 188 or, in other words, the distance between the balls 194 when the workpiece spring 188 is at rest, and / or the spring material 188. In a variant not illustrated, the invention relates to a range of several suspension systems. For example, the range comprises a first suspension system such as those described above, which has a first anchoring member, a first holding member and a first mechanical connecting interface which are configured so that the first member maintaining is mechanically secured with the first anchor member through the first mechanical linkage interface when the force exerted by the first holding member on the first anchor member is less than a first predetermined threshold value, and which are also configured so that the first holding member is released from the first anchor member through the first mechanical linkage interface when the force exerted by the first holding member on the first anchor member is greater than at the first predetermined threshold value. This range also comprises a second suspension system such as those described above, which has a second anchoring member, a second holding member and a second mechanical connecting interface which are configured so that the second holding member is 30. mechanically secured with the second anchor member through the second mechanical linkage interface when the force exerted by the second holding member on the second anchor member is less than a second predetermined threshold value, distinct from the first predetermined threshold value, and which are configured so that the second holding member is released from the second anchor member through said second mechanical connection interface when the force exerted by the second holding member 5 on the second anchoring member is greater than the second predetermined threshold value. For example, if it is first and second suspension systems similar to that described above and illustrated in particular in Figures 1 and 2, the first and second mechanical connection interfaces 10 may have distinct eigenfaces. In particular, the rods may be made of materials having different elastic and / or deformation properties, and / or may have different lengths, and / or different sections; and / or the positioning shoes may be located differently on the rods and thus the first and second distances between these shoes and the first and second jumpers respectively may be different; and / or the shapes of the beads may be different. Optionally, the first and second holding members may have fixing portions whose inner edges which define the outlines of the holes 57 are different.

In non-illustrated variants: the rods of the mechanical connection interface are not made of a composite synthetic material but rather of a metallic material; the at least partially circular spring piece is not made of a metallic material but rather of a composite synthetic material; the anchoring member does not have the form of a shackle but rather of a conventional hook; - The anchoring member is free of yoke, the fixing portion 30 of the holding member is supported on a single flange of the anchoring member; The system does not have a socket having a conical inner face and the fixing portion has an inner edge delimiting the contour of the hole formed therein, which inner edge has for example one or two chamfered faces; The holding member is devoid of an open sleeve; the open sleeve is directly integrated with the holding member; and / or - it is not a matter of suspending an optical fiber cable but rather of suspending an insulated electric cable, for example for a low, medium or high voltage overhead network, and the pole is not a pole of telecommunication but rather an electric pole. It is recalled more generally that the invention is not limited to the examples described and shown. 15
