Abstract

The cover for a cable joint comprises upper and lower shells (2,1) which are connected together but which can be separated by relative vertical movement. Each includes a joint face meeting along a median line (6). End plates (3) are fitted within the cover with their planes perpendicular to the longitudinal axis of the cover, each end plate having at least one hole for the passage and guidance of cables. Hinge elements and fixings (60) link the two shells together along their common joint line (6). Each end plate (3) has a slot (22), and the hole (20) through which the cable passes has a thin-wall plug surrounding it forming a seal. A further seal surrounds the outer edge of the end plate, forming a seal between the end plate and the upper and lower parts of the shell (2,1) which constitute the outer sleeve of the structure.

Description

 The invention relates to a closure member intended for the protection of a connection or splicing section of a communications cable, for example a fiber optic cable or the like, and more specifically relates to an improvement made to a member for closing a cable connector intended for a fiber optic cable.

 In general, a member for closing a cable connection comprises end plates through which cables are introduced, with the interposition of a cable connection section, and a cylindrical sleeve formed by two separate parts, intended to cover the cable connection section and having a construction allowing its division in the longitudinal direction. The two sleeve parts placed between the end plates are connected to each other by opposing stop parts, by means of a suitable fixing device, such as a bolt, a band or the like, so that the sleeve provides hermetic protection for the cable connection section.

 The conventional sleeve constructed so that it protects the cable connection section must have sufficient rigidity to prevent deformation of the sleeve, and sufficient properties to prevent the penetration of moisture inside. For this purpose, the sleeve has a construction such that the elements of the sleeve are intimately or closely coupled to each other, and the coupling of the cable and the sleeve is also carried out intimately.

Unfortunately, this construction of the conventional sleeve presents significant difficulties for the arrangement of the cable leaving the end plates and for the handling of the sleeve. In addition, the conventional sleeve has another drawback because it requires the storage of a cable provided with a hermetic member so that the cable is sufficiently fixed. However, the manufacture of the sleeve is then difficult and expensive, and the durability of the sleeve is reduced. In addition, for the conventional sleeve to have a satisfactory hermeticity, the shape of the fixing of the end plates must be strictly controlled, and the assembly of the sleeve is made laborious and long.

 In the conventional closure member, a support cable or metallic wire, for example an antenna wire, a communications cable or the like is fixed in the closure member by a cable clamp. This clamp has cable guide cavities which each allow the housing of a cable of maximum diameter. Thus, when a cable of smaller diameter is fixed in such a clamp, it is necessary to interpose a spacer or a sleeve of predetermined size between the cable and the cable guide cavity or wind the necessary number of turns of a ribbon d thickness determined around the cable.

 This adjustment of the external diameter of the cable to the cable guide cavity has usually been carried out on site, so that the replacement of the spacer or the winding of the ribbon is very inconvenient. In addition, a number of spacers or sockets having cable insertion holes of different diameters corresponding to cables of different external diameters should be kept, and chosen from among them.

 The present invention has been made to remedy the drawbacks of the prior art.

 It relates to the production of a member for closing a cable connection which makes it possible to avoid deformation during storage of a cable connection section.

 It also relates to the production of a closure member for a cable connection which facilitates the introduction and positioning of a cable relative to the closure member, while increasing both safety and hermeticity of the closing member.

 It also relates to the production of a closure member for a cable connection which allows easy and positive fixing of a cable relative to the closure member.

 It also relates to a member for closing a cable connection which can increase the possibilities of implementation during the assembly of the member for closure.

 It also relates to a cable connection closing member which allows a reduction in the number of elements which have to be replaced during installation or maintenance.

 It also relates to a cable connection closing member whose construction can be considerably simplified and whose manufacturing cost can be reduced.

 The present invention relates to a member for closing a cable connector. The closure member of the cable connection generally comprises a pair of sleeve members formed in a semi-cylindrical configuration and connected so that they can be separated vertically from each other, forming a cylindrical sleeve intended to surround a section of cable connection and having abutment joint surfaces formed on both sides, allowing the connection of the sleeve members, end plates placed at opposite ends of the sleeve and each formed with at least one guide guide hole cable intended for the introduction of a cable connected to the cable connection section, and joints and fixing members detachably hooked between the sleeve members so that the sleeve members can be connected to each other while the surfaces of seal in abutment are opposite. In the closure member according to the invention having this general construction, the end plates each have a slot which extends from a cable guide hole towards a part of the end plate near the external periphery of the end plate so that a wall of the end plate can be opened by cutting along the slot. The cable guide hole has a thin-walled cap which can be removed by cutting and the slot is removably mounted in the cap by a member ensuring the maintenance of rigidity. The closure member also includes a tape-like packing placed between the outer periphery of the end plate and an inner surface of the sleeve so that the outer end of the slot is covered.

 In the cable connection closing member according to the present invention having this construction, a sheath is removed from a cable over the required length, and an internal slit rod is cut to a predetermined dimension from the position of the cable at which the sheath has been removed, the operation being followed by the adjustment of tension members to a predetermined dimension, so that the preliminary arrangement allowing the cables to be connected is completed. Then, the sheath, at the predetermined position of the cable, is subjected to polishing and cleaning in the circumferential direction, the stiffness maintaining member is removed from the cable guide hole of each of the end plates, and the thin-walled cap is removed from the cable guide hole, and the slot is open. The slit is then spread so that it guides the cable through the widened slit towards the cable guide hole, so that the cable is introduced through the guide hole. Then, the slot receives a sealing member placed inside, with a connecting member preventing opening, so that the slot remains closed, and the adhesive tape-like lining is then glued to the outer periphery of the end plate so that it covers an end part of the slot contiguous to the external periphery, while conforming to its configuration. Then, spacers with the necessary diameter for a cable fixing clamp are mounted in the cable guide cavity and the curved holding member so that the sheath is fixed at the end of the cable to the clamp and the members clamps are attached to a cable tensioner clamp. Then, the upper member of the sleeve is pivotally moved around each of the joints on one side of the lower member of the sleeve while being held on the lower member of the sleeve by the joints, so that the upper member of the sleeve is placed on the lower member of the sleeve and pushes the end plates against the lower member of the sleeve.

Then, the fixing members are fixed in order from a central part of the sleeve members, so that the closing member is formed.

 The closure member thus assembled allows the mounting of a cable sealing member, and the mounting of the end plates is reinforced, with stabilization of the position of the closure member and of the sealing thereof. ci which increases a lot, so much so that the introduction of a gas into the cable connection closing member by a valve ensures that satisfactory clean operation is obtained.

 In addition, the separation of the fasteners allows the upper sleeve member to pivot easily around the joints, so that the sleeve opens and the operation of cable connection in the closure member can be easy. .

 A closure member for a cable connector according to the present invention is described below with reference to the accompanying drawings.

 Reference is first made to FIGS. 1 to 6 which show an embodiment of a cable connection closing member according to the present invention. In general, a member for closing a cable connector of the embodiment shown comprises a cylindrical sleeve constructed from a lower member 1 and an upper sleeve member 2, with end plates 3 mounted respectively in end adjustment portions 31 placed at opposite ends of the sleeve, in its longitudinal direction. The end plates 3 are each intended to allow the passage of at least one main fiber optic cable 10. The closure member of the embodiment shown also includes at least one cable clamp 4 intended to fix the cable 10 to the closure member and at least one tension member holding member 5 intended to be connected to a tension member (not shown) of the cable 10. The lower and upper members 1 and 2 of the cylindrical sleeve are each formed of a material based on a synthetic resin, such as a polypropylene resin, a fluorinated polypropylene resin flame retardant filled with glass fibers, a thermoplastic elastomer or the like, having a semi-cylindrical shape and mutually connected so that they can be separated vertically from one another, while also forming a cylindrical sleeve. For this purpose, the lower and upper members 1 and 2 of the sleeve have abutting joint surfaces formed on both sides and by which the members 1 and 2 are connected. The end plates 3 placed respectively in the end adjustment portions 31 placed at the two ends of the cylindrical sleeve thus formed may each consist of a suitable plate of rubber, for example of EPDM material (rubber of ethylene-propylene-diene monomer) in the form of a plate or the like, having satisfactorily the desired properties, for example of weather resistance, resistance to ozone and the like.

 The abutment joint surfaces of each of the lower and upper sleeve members 1 and 2, including a part intended to be brought into contact with the external periphery of each end plate 3, have recessed grooves 6 intended to be placed in the longitudinal direction or in the axial direction of the sleeve, for the packing retainer 7 as shown in Figure 1. The sleeve has a cable clamp 4 intended to be opposite one of the end plates 3. The cable clamp 4 comprises curved holding members 17 each intended to take the form of the external periphery of the cable. In addition, the sleeve has a fitting adjustment member 8 comprising a tension member holding member 5 and at least one tension member connector 9.

 The gasket 7 housed in each of the cavities 6 on both sides of the lower and upper sleeve members 1 and 2 is formed of an elastic material, for example of rubber or the like, and has an elliptical configuration in section. The gasket 7 is placed in the cavity 6 while being compressed so that a major axis of the section of the gasket 7 is made perpendicular to the abutment seal surface of the sleeve member or to the width direction of the cavity 6. In this way, the seal is ensured between the lower member 1 and the upper sleeve member 2.

 The cavities 6, as shown in FIGS. 4 to 6, are each formed in such a way that the two ends have a reduced width, and they thus form a part of the fitting ring 61 with force of packing intended to maintain by pressure the trim 7 inside. Thus, the fitting of the lining in each of the cavities 6 is carried out by force adjustment of the two ends of the lining 7 in the ring portions Gi of the cavity 6 with elongation of the lining so that the lining 7 is provisionally fixed or temporarily in the cavity 6. In this way, the fitting of the lining 7 in the cavity 6 is ensured positively, and the lining 7 cannot come out of the cavity 6 or tilt. The gasket 7 may comprise, at each of the two ends, a flange 71 if necessary. The flanges 71 can be brought into abutment under pressure against the external ends of the lower and upper members 1 and 2 of the sleeve so that the lining 7 is temporarily fixed in the cavity 6.

 In addition, the upper member 2 and the lower sleeve member 1 each have barrier members 65 placed in different parts delimited in front of the cavities 6 and on the two lateral edges, with a deviation in the longitudinal direction. During the assembly of the two members 1 and 2 for the formation of the sleeve, the members are connected with abutment of the members 65 of each sleeve member against the internal surface of the other sleeve member, so that the upper and lower members 2 and 1 cannot have a deviation in the horizontal direction.

 The upper and lower sleeve members 2 and 1 are connected to each other while being able to be separated vertically, with sealing interposition of the linings 7 and interposition of sealing members between the sleeve members and the plates 3 end, so that the closure member is hermetically closed. The upper and lower sleeve members 2 and 1 are connected so that they are secured to one another by the joint surfaces in abutment, using fixing or retaining devices. More specifically, the upper and lower members 2 and 1 of the sleeve are connected so that they are integral by articulations 60 each formed by a ring 61 in the form of a loop and by fixing members 70 each formed by a ring 71 in the form of a loop.

The rings 61 and 71 are arranged so that they can temporarily fix the sleeve members 1 and 2 to one another.

 In addition, the cable clamp 4 is mounted at each of the two ends of the connection adjustment member 8 fixed to the lower sleeve member 1, while being placed opposite an external surface of one end plates 3, and the clamp 5 of the tensioning member is mounted on the fitting adjusting member 8 by fixing screws. In this way, the fiber cables intended to be connected are well distributed and guided. In addition, the sleeve contains at least one storage unit for a fiber cable such that at least one storage tray 15 intended to be placed in the middle part. In addition, the sleeve is mounted on this plate with the connectors 9 for tension members as shown in FIGS. 1, 3 and 4.

 Each of the end plates 3, as shown in FIGS. 7 to 12, is constructed of an elastic rubber material, of rounded shape, for example elliptical, elongated oval, circular or the like, with at least one guide hole or cable introduction. In the embodiment shown, four cable guide holes 20 are incorporated. These holes 20 can be made with the same diameter or with different diameters. The end plates 3 each have caps 21 of reduced wall thickness intended to cover the respective cable guide holes 20. The caps 21 are each placed on an end plate 3 so that it can be removed by cutting out the end plate 3. In addition, the end plates 3 each have slots 22 which correspond to the guide holes 20. The slots 22 are arranged so that a first end communicates with the corresponding cable guide hole 20 and that the other end extends towards a part of the end plate 3 near its outer periphery. In addition, the slots 22 are each arranged so that they are oriented obliquely, in an inclined direction relative to the horizontal direction. The slots 22 are each closed on a first side and at their periphery by elements 221 and 222 with thin walls, when the cable 10 is not introduced into the corresponding hole 20. When the cable 10 is introduced into the hole 20, the cap 21 intended to cover the hole 20 is removed by cutting and the thin-walled elements 221 and 222 of the end plate 3 are opened by cutting along the slot 22 , so that the end of the slot 22 can be wide open. In this way, the operating properties of the cable connection and the hermetic properties of the cable are significantly increased.

 Each of the slots 22 and each of the guide holes 20 in which a cable is not introduced are removably provided with a sealing member 251 ensuring the maintenance of rigidity and with a stiffness maintaining member 25 respectively . In addition, each of the end plates 3 has, at its two lateral sides, a pair of cavities 23. The cavities 23 each allow the firm mounting of a connecting member 24 preventing opening, intended to be arranged vertically at the above two sides of each slot 22 so that the end plate 3 cannot open. The end plate 3 also has, in a central part, between the guide holes 20 of the two pairs, a cavity 28 in which is firmly fixed to the member 29 for maintaining rigidity intended to be in abutment against an end wall of the sleeve. The connecting member 24 housed in each of the cavities 23 forms an end piece intended to prevent the opening of the external periphery of the end plate 3 and its movement, when the slot 22 is opened by cutting or is expanded for the introduction of the cable 10 into the hole 20, before closing again.

The connecting members 24 intended to prevent the opening and the member 29 for maintaining rigidity, which are held in the cavities 23 and 28 respectively formed on the external surface of the end plate 3, have, on the turned surfaces towards the end plate 3, complementary cooperation members 242 and 292 respectively. These members 242 and 292 cooperate with cavities 241 and 29l formed on the end plate 3 and thus ensure positive maintenance of the members 24 and 29 on the end plate 3, so that these members can practically not separate .

 The cable is introduced into the end plate 3 by removing the member 25 for maintaining rigidity in the hole 20 into which the cable is to be inserted, by selective removal of the thin-walled cap 21 by cutting the hole 20 so that it is open, by cutting the elements 221 and 222 of the end plate 3, towards the external periphery of the slot 22 and along the latter which communicates with the hole 20, so that the external end of the slot 22 can be opened widely, the cable 10 then being inserted laterally into the open slot 22, towards the hole 20. The cable is then introduced into the hole 20 so that the slot 22 returns to its original configuration such that the sealing member 251 is introduced, before bonding of the sealing member 251 to the slot 22 with an adhesive if necessary. Then, the connecting member 24 intended to prevent opening is mounted in the cavity 23, so that the two sides of the end plate 3 are fixed around the slot 22. When the end plate 3 has a small dimension, it is not compulsory to mount the member 25 for maintaining rigidity. Furthermore, when the end plate 3 has one or two cable guide holes intended to be placed on a horizontal central axis, the slots 22 can be placed along the horizontal central axis.

 In addition, the end plates 3 each have an external peripheral surface provided with several grooves 26 forming ridges and hollows, in the circumferential direction, so that they allow the production of a compressive force between the internal surface of the sleeve and the end plate 3, so that the hermeticity of the closure member is increased. In addition, this compression allows the compression force to be transmitted inwards and therefore gives a satisfactory hermetic seal between the cable 10 and the end plate 3 at a cable outlet hole or hole 20. In in addition, a lining 11 similar to an adhesive tape, formed of a material based on unvulcanized butyl rubber, is placed locally between the external periphery of the plate 3 and an internal surface of the end piece portion 31 of the sleeve, so that the outer end part of the slot 22 contiguous to the outer periphery of the plate 3 is covered. This lining 11 is placed by bonding to the outer periphery of the plate 3 and takes the form of this outer periphery, including grooves 26 forming ridges and hollows. Thus, the seal between each end piece 31 of the sleeve and the plate 3 is preserved in such a way that the fixing force created by the fixing members 70 is collected by the upper and lower members 2 and 1 of the sleeve. , then transmitted by these to the grooves 26 formed on the external peripheral surface of the plate 3. The assembly and disassembly of the closure member of the embodiment shown are thus much easier, without the need for d '' use any separate trim on the end plate.

 The end plate 3 has, on its internal surface, a holding member 31 intended to ensure a more secure arrangement of the plate 3 by preventing its deformation by application of an external force. To this end, the holding member 31 has a cavity 30 in which is housed a projection 40 formed in the cable clamp 4 as shown in FIG. 8.

 In addition, the end plate 3 is constructed so that it can accommodate cables of different diameters. For this purpose, a spacer 43 formed from a material based on a resin or rubber is used for adjusting a diameter of the cable guide hole 20 of the plate 3 according to the diameter of the cable which must to be introduced.

Alternatively, an airtight tape can be used for this purpose. The spacer 43 or the hermetic tape is wound on the cable 10, and it ensures intimate contact of an outer peripheral surface of the cable 10 with an inner peripheral surface of a through hole formed from the cable guide hole 20 .

 The spacer 43 placed at the periphery of the cable leaving the sleeve, as shown in FIGS. 13A to 13C, has a hollow cylindrical shape and has a slot 44 for introducing cable on one side, so that the spacer 43 can be opened from one side. In addition, the spacer 43 has, on its internal and external surfaces, annular grooves 46 and 45 delimiting ridges and hollows, so that satisfactory airtightness is obtained for the spacer 43 and facilitates assembly and disassembly of the spacer 43 on the cable 10.

 The spacer 43 is placed in natural conditions and is therefore constructed of a rubber-based material or the like which can shrink or expand depending on the temperature of the medium, so that the pressure variation between the outer periphery of the plate 3 and the sleeve and between the inner periphery of the cable guide hole and the outer periphery of the cable is minimized and gives a satisfactory compressive force while preventing shrinkage due to a reduction in temperature. So that the hole 20 for guiding the plate 3 allows the selective introduction of cables 10 of different diameters without changing the diameter of the hole 20, several spacers 43 can be prepared by making with an external diameter equal to that of the hole 20 and internal diameters corresponding to the external diameters of the cables.

 When using an airtight tape for sealing between the hole 20 and the outer periphery of the cable 10, the sealing tape can be formed from a rubber material of low hardness, for example having a Shore hardness (Hs) from 0 to 30, having a significant elongation and a tensile stress or a significant tensile modulus. Such a rubber-based material can be formed from a composition of a thermoplastic rubber, for example EPDM, of silicone, of butyl rubber, of butadiene-styrene rubber, of fluorinated rubber or the like, having a penetration of 4 to 9 mm and preferably 5 to 7 mm, measured according to the Japanese industrial standard JIS K 2560, an elongation of 1,500 to 2,000 W and preferably 1,700 to 1,900 a (standard JIS K 6301), and constraints tensile strength of 5.104 Pa at 100 k elongation, 105 Pa at 300 9 s elongation and 1.4.105 Pa at 400 k elongation (JIS K 6301 standard). More specifically, the rubber material can have a density of 1.0 to 1.05, a tensile strength of 3.1.106 Pa and a residual compressive deformation of 63.0 W (after 22 h at 70 CC) .

The hermetic tape formed of such a low hardness rubber material can be elastically deformed so that it corresponds to the outer peripheral surface of a cable sheath or support wire having irregularities or linear protrusions formed in such a way. that the hermetic tape is brought into contact with the outer peripheral surface intimately without spacing, with a satisfactory seal.

 The cable clamp 4 as shown in FIGS. 14 to 19C comprises a clamp body 41 formed with several cable guide cavities 6, and the curved holding members 17 are each mounted in a separable and pivotable manner on the body 41 by a pin 18, so that they are opposite a corresponding cavity 16.

The curved holding members 17 each have a configuration allowing it to surround the external periphery of the cable 10 in cooperation with a corresponding cavity 16.

The curved member 17 is then fixed to the body 41 of the clamp 4 by a screw 19 forming a cable holding member so that it is placed between the body 41 and the member 17. Thus, it is noted that the clamp 4 facilitates tightening the cable. More specifically, the curved member 17 is placed in front of a corresponding cavity 16 and comprises an arm-like member which, at one end, has the pin 18 allowing the pivoting movement of the member 17 and, at the other end or free end 171, has a hole 172 for introducing a screw 19. The pin 18 has two parallel surfaces and is removably mounted in a mechanism intended to prevent separation, placed in the body 41, so that the pin 18 is pivotally supported on the body 41 of the clamp 4. In the embodiment shown, the mechanism intended to prevent the release is provided with cavities 181 each formed with a narrow opening which allows the introduction of the two parallel surfaces of the spindle 18 in the cavity 181. The screw 19 or the fixing member of each of the curved members 17 is screwed into a pivoting element 191 supported so that it can pivot on the body 41 d e the clamp 4 and has a head 192 retained on the free end 171 of the member 17.

 In addition, the cavity 16 and the member 17 have on their internal surface, several annular projections 182 and 173 respectively, forming cavities 37, and spacers 33 intended to be in abutment against a sheath of a cable are mounted so removable in the cavities 37. The spacers 33 are each in the form of a curved element having, at its internal peripheral surface, grooves 38 forming ridges and hollows, with a peripheral surface provided with a flange 32. The spacer 33 has a projection 34 at its outer peripheral surface. The spacers 33 are each temporarily mounted in the cavity 37 formed in the cavity 16 or of the member 17 while the projection 34 is mounted in a hole 36 of the cavity 16 of the guide cable or of the curved member 17.

 Reference is made to FIGS. 20 to 29 for the description of another example of cable clamp 4. In this example shown, the clamp 4 comprises a body 41 having cavities 16 and curved members 17 for holding. The cavities 16 and the curved members 17 have adjustment or complementary surfaces 161 and 174 respectively on which are placed by sliding respective complementary surfaces 331 formed on the spacers 33, so that the spacers 33 are removably mounted in pairs in the cavities 16 and the curved members 17 so that they are opposite. The curved members 17 are each fixed to the body 41 of the clamp 4 by a screw 19.

 The spacers 33, as shown in FIGS. 23A to 23E, each have, at their opposite ends, a pair of curved concave surfaces 54 and 55 of different curvatures corresponding to external peripheries of cable of different diameters and having curvatures of opposite directions .

The curved concave surfaces 54 and 55 of the spacer 33 each have several ribs 57 which protrude at certain intervals and are placed in a direction perpendicular to the axis of the cable. Each of the spacers 33 having this construction is mounted on the body 41 or one of the members 17, while a spacer 56 of suitable thickness is optionally placed between the spacer 33 and the body 41 or the member 17.

 In a variant, shown in FIGS. 24, 25 and 26A to 26F, the spacers 33 may each be formed of a first member 33a and of a second spacer member 33b connected in a separable manner by at least one curved surface formed so that it corresponds to an external periphery of a cable. In this case, the first spacer member 33a has, at one end, a curved surface 54 of small radius and, at the other end, a curved concave surface 55 of large radius, having a curvature of opposite direction and having two mounting holes 39. The curved surfaces 54 and 55 of the first spacer member 33a have several ribs 57 which protrude. The second member 33b has a curved convex surface 41 at a first end, corresponding to the concave surface 55 of the first member 33a and carrying two rods or connecting pieces 42 intended to be housed in respective holes 39 for mounting the first member 33a. The second member 33b also has, at the other end, a curved surface 52 of intermediate radius. The curved surface 41 has several grooves 58 in which the ribs 57 of the member 33a are housed. This construction of the retaining spacer, comprising several members 33a and 33b, can be widely applied to various cables of different diameters.

 As described above, the spacer 33 which has, at its two ends, the curved surfaces 54 and 55 which correspond to the external peripheries of the cables allows the use of each curved surface for a cable of large diameter or of small diameter, with a suitable spacer 56 selectively interposed. In addition, in the cavity 16 of large radius, the spacer 33, having the first and the second member 33a and 33b connected in a removable manner by the surfaces 41 and 55, must be used selectively, the first member 33a is mounted in the cavity 16, alone or in combination with the second member 33b depending on the diameter of the cable as indicated in FIGS. 26A to 26I. Consequently, this spacer widens the range of applications to cables of various diameters.

 The mounting or complementary surfaces 161, 174 and 331 may have several linear projections which are parallel to the axis of the cable or, on the contrary, triangular teeth, undulations or crenellated projections so that the assembly or replacement of the spacers 33 or spacer members 33a and 33b can be easily produced. The mounting surfaces 16l, 174 and 331 thus produced facilitate the adjustment of the position of each spacer 33 in the radial direction relative to the cable and allow the elimination of the spacer 56, unlike the above embodiments.

 As shown in Figures 33A to 34, the body 41 of the clamp 4 may have at one end of each surface 161, in which the spacer 33 is slidably housed, a pair of parts 42 preventing separation, so that 'an intermediate space is defined. The spacer 33 is formed so that it protrudes at one end with two pawls 332 for cooperation. The pawls 332 enter the space between the parts 42 and a stop member 53 is housed between the pawls 332 and fixes these on the parts 42 so that the spacer 33 cannot come out.

 The joints 60 and the fastening members 70 will now be described in more detail with reference to FIGS. 35A to 40B.

 One of the sleeve members 1 and 2, or the lower member 1, has a part close to a lateral edge having several projections 63 of annular housing spaced apart from one another in the longitudinal direction. In each projection 63, an articulation member is pivotally disposed and comprises the ring 61 in the form of a loop. In addition, the lower sleeve member 1 comprises, in a part close to the other lateral edge, several projections 731 for housing the fixing member intended to be spaced in the longitudinal direction. In addition, the other member or upper sleeve member 2 comprises, in a part close to one of the lateral edges, several retaining projections 631, spaced from one another so that they correspond to the articulation members 60 and , in a part close to the other lateral edge, several projections 73a of annular housing corresponding to the projections 731. The rings 71 in the form of a loop are arranged so that they can move by pivoting in one of the corresponding projections 73 of housing. The ring 71 in the form of a loop is pivotally mounted, with an operating lever 75 placed at its outer end, on a retaining projection 74.

 The fastening members 70 placed on a first side of the members 1 and 2, as indicated in FIG. 39, each comprise a ring 71 in the form of a loop constituted by a metal rod and housed in a cavity 72 for introduction of ring formed on the projection 73 placed at a lateral edge of the upper sleeve member 2, the lever 75 being associated with the retaining projection 74, and a cavity 721 formed on the projection 731 at a lateral edge of the member 1 The projection 74 for holding the lever 75 is held by the projection 721 so that it separates, and it therefore plays the role of a support point. In addition, the joints 60, as shown in FIG. 36, each have the ring 61 formed of a metal rod and pivotally fixed in a ring insertion part 62 formed on the projection 63 placed at the other lateral edge of the member 1, and a ring retaining cavity 621 formed on the hinge holding projection 63l of the upper member 2 and in which the other end of the ring 61 is retained so removable. This construction of the articulation 60 and of the fixing member 70 facilitates the connection and separation of the members 1 and 2.

 In addition, the loops 61 and 71 in the form of a loop of the articulation 60 and of the fixing member 70 placed at the opposite ends of the sleeve in the longitudinal direction are each movable with a retaining member 77 along one side. outer of each of the linings 7 intended to be housed in a cavity 76 formed by a chamfer at the outer lateral edges of the joint abutment surfaces of the members 1 and 2. The retaining member 77 can be formed for example of an annular rod . This construction, when a sticky sealing material is loaded between the abutting joint surfaces of the members 1 and 2, effectively prevents the evacuation of the sealing material.

 The reference 64 designates stop members each placed in the vicinity of the projection 63 for housing the ring of the lower member 1. The stop members 64 each hold the ring 61 of the joint 60 at a predetermined angle. pivoting around the part 62. The mounting of the member 2 on the articulations 60 is carried out by abutment of the ring 61 against the stop member 64 so that the ring 61 cannot move by pivoting, and the upper member 2 is then placed on the lower member 1. Then, the upper member 2 is lifted around the lining 7 placed on one side of the joints 60 so that a free end of the ring 61 cooperates with the cavity 621 of the projection 631. This operation brings about the simultaneous cooperation of several rings 61 with the cavities 621, so that the members 1 and 2 can be connected from one side to the other. by the joints 60 in a single operation. Then, the members 1 and 2 are connected on the other side to each other by the fixing members 70 as shown in FIG. 39.

 The mechanism for the stop member of the articulations 60 may have a construction formed at the end surfaces of the members 1 and 2 placed facing each other when the lateral edges of the members 1 and 2 are aligned, in place of the stop members 54. For this purpose, the end surfaces may each have a surface part inclined downwards and outwards, so that an angle O of 30 to 900 can be delimited between the inclined surface parts and therefore between the two end surfaces. The end surfaces thus formed allow the inclined surfaces to abut so that they form a stop mechanism, when the members 1 and 2 rotate in the direction of opening. There is therefore a limitation of the opening angle of the members 1 and 2 to a range of 30 to 900. This adjustment of the opening angle of the members 1 and 2 to the aforementioned range prevents the upper member 2 to tilt excessively on the side opposite the working side, so that the workability obtained is satisfactory.

 So that the rings 61 and 71 of the articulation 60 and of the fixing member 70 are used in the same way, the ring insertion part 62 and the ring retaining cavity 621 of the articulation 60 may be made in substantially the same manner as the portion 72 and the cavity 721 of the member 70, and, in addition, the ring housing projection 63 and the ring retaining projection 63l of the joint 60 may be constructed in substantially the same manner as the projection 73 and the projection 731 of the fixing member 70. In this way, the mold of members 1 and 2 is simplified. Furthermore, the rings 61 and 71 can be constructed in practically the same way and can therefore be used in common with the two lateral edges of the sleeve.

 The member 5 for holding the tension member, as shown in FIGS. 41A and 41B, is mounted with a clamp 51 of the type with a single hole or with several holes, comprising one or more cable insertion parts placed on a mounting plate 49, with the interposition of one or more arms 48. The clamp 51 is fixed to the lower member 1 so that the cable tension member is maintained. For example, the clamp 51 placed in the member 1, as indicated in FIGS. 41A and 41B, can be produced so that one or more members 47 in which the tension members are inserted are mounted on the plate 49 at the using the arm or arms 48. The members 47 each have a screw 50 for fixing. The clamp 51 of the tension member having this construction is then mounted on the tension member holding member 5 and facilitates the application of a tension to the center of at least one of the cables.

 One of the members 1 and 2 or the plate 3 may have a gas inlet provided with a valve (not shown) allowing the introduction of a sealing gas into the closure member so that the connection section cable is protected in the closing member.

 We will now describe the assembly of a cable connection closing member of the embodiment having this construction.

 A sheath is removed over the desired length of each of the cables 10 and an internal slit rod is removed over a predetermined distance from the location of the cable from which the sheath was removed, before adjusting the tension members to a predetermined size, so that the preliminary arrangement for cable connection is made. Then, the sheath, in the predetermined position on each cable 10, is subjected to polishing and to cleaning in the circumferential direction, and the spacer 43 is mounted on the cable 10 or the hermetic tape is wound on the cable 10. The members 25 and 25 for maintaining rigidity are removed respectively from the hole 20 and from the slot 22 of each end plate 3, and the thin-walled cap 21 and the thin-walled elements 221 and 222 of the plate 3 are removed respectively from the plate 3 by cutting so that the hole 20 and the slot 22 are open. The slot 22 is then widened for guiding the cable 10 in the slot 22 towards the guide hole 20, so that the cable 10 is inserted in the hole 20.

Then, the slot 22 of the plate 3 is mounted with the member 251 for sealing and maintaining rigidity, then is disposed with the connecting member 24 intended to prevent opening so that the slot 22 is closed, and the adhesive lining 11 is then glued to the external periphery of the end plate 3 so that it covers the external end part of the slot 22 contiguous to the external periphery while taking the configuration of the external periphery of the plate 3 end. Then, the spacers 33 having the internal diameter necessary for the clamp 4 are mounted in the cavity 16 and the curved member 17 so that the sheath is fixed to the end of the cable 10 on the clamp by tightening the screw 19 with a predetermined torque, and so that the tensioning members are fixed to the clamp 54 of the member 5 for holding the tensioning member by fixing the screws 50, with a torque of predetermined value. Then, the linings 7 are placed between the abutment joint surfaces of the lower and upper members 1 and 2, and the upper member 2 is pivotally moved around each articulation 60 on one side of the lower member 1 while being held on the lower member 1 by the joints 60, so that the upper member 2 is placed on the lower member 1 with displacement of the plates 3 against the member 1 by force, so that the joint surfaces in abutment of the members 1 and 2 can be abutted mutually. The fastening members 70 are then fixed from the central part of the sleeve members towards the end parts, for the formation of the sleeve. The sleeve thus produced may possibly undergo a tape winding intended to maintain hermeticity over its entire length so that it exhibits hermeticity with great reliability.

 In the mounted closure member of the embodiment shown, the linings 7 are all kept compressed in the direction of the major axis between the abutment joint surfaces of the members 1 and 2, so that the closure member is hermetic increased for a relatively low clamping force. In addition, the spacer 43 or the hermetic tape is placed in the axial direction of the cable 10 between the plate 3 and the cable 10 and forms a sealing material which stabilizes the position of the members 1 and 2, which facilitates the mounting of the sleeve. , and which increases the hermeticity of the sleeve. The gasket 7 has an elliptical sectional shape and it is placed in the cavities 6 of the members 1 and 2 corresponding to their long axis, in the direction of the clamping force between the sleeve members, so that an effect of sealing lip is obtained, and the mounting of the closure member can be facilitated and the hermeticity can be increased.

 The disassembly of the closure member is described below.

 First, the lever 75 for maneuvering each member 70 is pivotally displaced so that the projection 74 is separated from the projection 731 for fixing member housing and that the connection of members 1 and 2 is removed, and the member 2 can easily be moved by pivoting around the joints 60 for opening the sleeve.

Then, the members 24 are removed from each of the end plates 3, before separation of the members 1 and 2 from each other, that a tray occupying a necessary position can be opened, so that the workability is further increased.

 The embodiment considered has a construction which allows the connection and fixing of the sleeve members only on one side of the sleeve. This construction, even when a sufficient working space on the other side of the sleeve is not available, allows an operation of mounting another closure member in an easy manner since the working space is kept on the worker's side (first side of the sleeve). When the members 1 and 2 which are connected by the joints 60 and the fixing members 70 are open, the mechanism with stop member associated with each joint 60 limits the opening angle of the two members 1 and 2. Thus, the relative pivoting movement of the two members of the sleeve in the opening direction is limited to a predetermined angle, and thus eliminates the drawback of excessive opening of one of the members when the other is in cooperation with the connection section, and with movement by pivoting towards a side opposite to the working side, so that the workability is then deteriorated.

 In addition, in the closure member of the embodiment shown, the lower and upper sleeve members 1 and 2 have a construction of practically the same configuration, so that the mounting of the fixing and articulation members ensuring the connection of the two sleeve members can be produced without it being necessary to distinguish the two sleeve members. This also allows the manufacture of the two sleeve members with a single mold.

 The sleeve members may each have, on the internal and external surfaces, a corrugated shape and may be made of a material having a satisfactory residual compression, for example a thermoplastic elastomer of olefin or styrene. This construction easily allows the manufacture of the sleeve at a reduced cost, and facilitates the recovery and recycling of the sleeve, since any vulcanization treatment is eliminated.

 As indicated in the foregoing description, the cable connection closing member according to the present invention allows the sleeve members to be securely fixed to one another by fixing members with abutment of the surfaces. of joint in abutment of the sleeve member, so that the connection of the sleeve members and the protection of the connection section are easy, with obtaining a satisfactory seal of increased reliability thanks to the uniform pressure exerted between the plates d end and minimizing the number of locations to which the attachment is made. In addition, the handling of the closure member is simplified and assembly and disassembly are facilitated while maintaining a stable position of the sleeve. In addition, a limited number of elements can be used widely for various cables of different diameters and for the positive fixing of the fixing member, so that the time required for mounting or dismounting the fixing member is reduced. , the disadvantages of storing different elements of installation or maintenance are eliminated, and the cable connection closing member can be produced with a simple structure and a reduced cost.

 Of course, various modifications can be made by those skilled in the art to the closure members which have just been described solely by way of nonlimiting example without departing from the scope of the invention.
