Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of suspension wires, and in particular to a suspension wire and a suspension wire assembly. Background Art

[0002] Adjacent distribution poles are usually connected with cables, which need to be suspended by suspension wires. However, the cables are generally equipped with power supply wires, and the suspension wires are mostly metal wires. In actual use, damage to the cables may cause the suspension wires to be energized, resulting in low safety. Utility Model Content

[0003] The embodiments of the present application provide a suspension wire and a suspension wire assembly, which are intended to solve the problem that the suspension wire may be electrified due to cable damage, thereby resulting in low safety.

[0004] In a first aspect, an embodiment of the present application provides a suspension wire, comprising a wire core and an insulation layer, wherein the insulation layer is coated on the outside of the wire core, and the suspension wire also comprises a hanging portion, which is located on the outside of the insulation layer and connected to the insulation layer, and the hanging portion is configured to hang a cable.

[0005] The suspension wire provided in this embodiment has an insulating layer coated on the outside of the wire core, and the mounting portion is located on the outside of the insulating layer and connected to the insulating layer. Therefore, the cable can be mounted on the mounting portion. Since the insulating layer is coated on the outside of the wire core, the mounting portion can achieve insulation between the wire core and the cable through the insulating layer when mounting the cable. In this way, when the cable is damaged, the insulating layer can prevent the wire core from being charged. In other words, even if the cable is damaged, the wire core will not be charged, thereby improving the safety of the suspension wire. At the same time, when using the mounting portion to suspend the cable, there is no need to bundle the two together, which helps to reduce the difficulty of hanging it.

[0006] In some embodiments that may include the above embodiments, the insulating layer includes at least one of a high-density polyethylene layer and a thermoplastic polyurethane layer. This arrangement can ensure that the insulating layer has good insulating properties and good structural stability.

Thus, the high-density polyethylene layer and the thermoplastic polyurethane layer can be used to improve its insulation performance.

[0008] In some embodiments that may include the above embodiments, the wire core includes a plurality of sub-wire cores twisted together. Through the above arrangement, the plurality of sub-wire cores are twisted together to form the wire core, so that the bending resistance and tensile strength of the wire core can be enhanced, so that after the cable is mounted on the mounting portion, the influence of the weight of the cable on the deformation of the wire core can be reduced, thereby reducing the risk of damage to the insulation layer caused by deformation of the wire core, and the twisted plurality of sub-wire cores are conducive to reducing the radial size of the wire core to reduce the volume of the wire core.

[0009] In some embodiments that may include the above embodiments, the wire core includes a plurality of sub-wire cores arranged in parallel, thereby facilitating reducing the difficulty of designing the wire core.

[0010] In some embodiments that may include the above embodiments, the wire core includes a non-metallic wire core.

[0013] In some embodiments that may include the above-mentioned embodiments, the core includes a glass yarn core and a fine fiber reinforced composite material core. The glass yarn core and the fine fiber reinforced composite material core are twisted to form a dense and soft reinforcement, so that the core has a certain tensile and bending resistance.

[0014] In some embodiments that may include the above embodiments, the core includes a fine fiber reinforced composite core and an aramid core, and the fine fiber reinforced composite core and the aramid core are twisted to form a dense and soft reinforcement, so that the core has a certain tensile and bending resistance.

[0015] In some embodiments that may include the above-mentioned embodiments, the core includes a glass yarn core, an aramid core and a fine fiber reinforced composite core. The glass yarn core, the aramid core and the fine fiber reinforced composite core are twisted to form a dense and soft reinforcement, so that the core has a certain tensile and bending resistance.

[0016] In some embodiments that may include the above embodiments, the wire core further includes an adhesive, and the adhesive is filled in the non-metallic wire core. By providing the adhesive to fill the gaps in the non-metallic wire core, the density of the non-metallic wire core is increased so that the non-metallic wire core forms a dense structure, thereby enhancing the tensile and bending resistance of the non-metallic wire core.

[0017] In some embodiments that may include the above embodiments, the wire core includes a metal wire core. This arrangement makes the structural strength of the wire core higher, thereby reducing the problem of sag change in the wire core after the mounting part mounts the cable.

[0018] In some embodiments that may include the above embodiments, the mounting portion and the insulating layer are an integral structure, so that the mounting portion and the insulating layer can be integrally formed, so as to reduce the difficulty of manufacturing the mounting portion and the insulating layer.

[0019] In some embodiments that may include the above embodiments, the mounting portion and the insulating layer are separate structures, thereby facilitating the separate design of the shape and structure of the mounting portion to improve the practicability of the mounting portion.

[0020] In some embodiments that may include the above embodiments, the mounting portion is rotatably connected to the insulating layer, and the axis of the rotation axis of the mounting portion is perpendicular to the center line of the wire core. Thus, the relative angle between the mounting portion and the wire core can be changed by rotating the mounting portion, so that the mounting portion can mount cables extending in different directions, thereby facilitating the construction and cable threading operation.

[0021] In some embodiments that may include the above embodiments, one of the insulating layer and the mounting portion is provided with a groove and the other is provided with a connecting protrusion, and the connecting protrusion is rotatably arranged in the groove. In this way, the mounting portion and the insulating layer can be rotatably connected, and the connection method is relatively simple, which is conducive to reducing the difficulty of manufacturing.

Such an arrangement can realize a rotatable connection between the mounting portion and the insulating layer, and the connection method is relatively simple, which is conducive to reducing the difficulty of manufacturing.

[0024] In some embodiments that may include the above embodiments, the mounting portion includes a mounting ring, and the mounting ring forms a cable threading space for the cable to be threaded. In this way, after the cable is threaded in the cable threading space, the mounting ring can limit the cable on the circumferential outer side of the cable to prevent the cable from escaping from the mounting ring, thereby ensuring the mounting stability of the cable by the mounting ring.

[0025] In some embodiments that may include the above embodiments, on a horizontal plane perpendicular to the direction of gravity, the projection of the center line of the cable core falls on the center line of the cable threading space. In this way, after the cable is threaded along the cable threading space, the extension direction of the cable will be roughly parallel to the extension direction of the center line of the cable core, thereby ensuring that the cable can be routed roughly along the center line direction of the suspension wire to meet the cable routing requirements.

[0026] In some embodiments including the above embodiments, the mounting ring is provided with an opening, which is communicated with the cable threading space. Such an arrangement enables the cable to be placed on the mounting ring or taken out from the mounting ring through the opening, thereby reducing the difficulty of mounting and taking out the cable.

[0027] In some embodiments that may include the above embodiments, the distance between the opening and the highest point of the mounting ring is smaller than the distance between the opening and the lowest point of the mounting ring. Thus, at least a portion of the opening is located above the center line of the mounting ring, so that the cable can be prevented from being separated from the mounting ring through the opening, thereby ensuring the mounting stability of the cable.

[0028] In some embodiments that may include the above embodiments, the mounting portion includes a connecting rod and a hook, the connecting rod is connected between the insulating layer and the hook, and the hook is used to mount the cable. Thus, the mounting portion is formed into a hook structure including the connecting rod and the hook, so that it is convenient to better mount the cable, and the setting method is simpler, which is conducive to reducing costs.

[0029] In some embodiments that may include the above embodiments, a plurality of mounting parts are provided, and the plurality of mounting parts are spaced apart in a direction parallel to the center line of the wire core. In this way, the pressure of the cable can be dispersed through the plurality of mounting parts to reduce the force on a single mounting part.

[0030] In some embodiments that may include the above embodiments, the distance between two adjacent mounting parts is in the range of 0.5m-0.8m. For example, the distance between two adjacent mounting parts may be 0.5m, or 0.6m, or 0.7m, or 0.8m, that is, when the distance between two adjacent mounting parts is within the above value range, the distribution of the mounting parts can be more balanced, and the pressure of the cables can be dispersed through multiple mounting parts to reduce the force on a single mounting part, thereby enhancing the mounting capacity of the mounting parts.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0051] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0052] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left", "right", "horizontal" and "vertical" are defined relative to the orientation of the components schematically placed in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components placed in the drawings.

[0053] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, an electrical connection, a coupled connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0054] The embodiment of the present application provides a suspension wire assembly, which includes a suspension wire and a cable. The suspension wire assembly can be applied to a power system or a communication system, and the cable can include an optical cable or a wire. The power system and the communication system both include a plurality of distribution poles, each of which is set up on the ground; the suspension wire is suspended on each distribution pole, and the cable is mounted on the suspension wire to fix the cable through the suspension wire. When the suspension wire assembly is applied to the power system, the cable includes a wire and is used to transmit power. When the suspension wire assembly is applied to the communication system, the cable includes an optical cable and is used to transmit signals.

[0055] In order to clearly express the structure of the suspension wire assembly provided by the present application, the following example is given by taking the suspension wire assembly as an example for application in a communication system. Figure 1 The communication system includes a machine room 100, a control device 102, an optical cross-connection box 104, a signal line 105, a junction box 103, an outdoor cabinet 101 and a distribution pole 400. The signal line 105 is led out from the machine room 100 and connected to the control device 102. Then the signal line 105 is led out from the control device 102 to the optical cross-connection box 104. Then the signal line 105 is branched by the optical cross-connection box 104 and led out to the junction box 103, and led out from the junction box 103 to the outdoor cabinet 101. The signal line 105 is branched and led out from the optical cross-connection box 104 to a distribution cable 107 connected to a two-branch box body 106 fixed on the distribution pole 400. Each distribution pole 400 is provided with a two-branch box body 106, and two adjacent two-branch box bodies 106 are connected by a distribution cable 107. Then the household cable is pulled from the two-branch box body 106 to the user 300. Among them, a signal transceiver is usually provided in the computer room 100, and the signal transceiver is connected to the signal line 105 for transmitting or receiving signals, and the control device 102 is used to control whether the signal line 105 transmits signals, the optical cross-connect box 104 is used to connect the signal line 105 with the distribution cable 107, the outdoor cabinet 101 is generally provided with a computer and related control equipment and is used to monitor whether the communication system can work normally, and the two-branch box body 106 is used to divide the distribution cable 107 so that the distribution cable 107 can be divided into household cables.

[0056] It is understood that in the embodiment of the present application, the cable may include a distribution cable and / or a drop cable. Exemplarily, the distribution cable and the drop cable may include an optical cable or a wire for transmitting signals.

[0057] In the above implementation, the distribution cable includes an optical cable, and the distribution cable may include an all-dielectric self-supporting optical cable (ADSS). Figure 2The all-medium self-supporting optical cable 500 includes a plurality of sub-cables, wherein several sub-cables can be coated in fibers and fillers 504 to form an optical cable bundle, a loose tube 503 is provided on the outer side of the optical cable bundle, and the optical cable bundle can be provided with a plurality of optical cable bundles, which are twisted and arranged on the outer side of the steel core 505, a water-blocking yarn 506 is provided between two adjacent optical cable bundles and the steel core 505, and the optical cable bundle and the steel core 505 can be coated in a water-blocking tape 507, the outer side of the water-blocking tape 507 can be coated with aramid yarn 502, the outer side of the aramid yarn 502 can be wound with a parachute opening rope 508, and the outer side of the aramid yarn 502 can be coated with an outer sheath 501. The drop cable includes an optical cable, and the drop cable can include at least one optical fiber and a protective layer coated on the outer side of the optical fiber. Exemplarily, the sub-cable can be connected to the drop cable through a two-point box body to achieve the connection between the drop cable and the distribution cable.

[0058] Please continue to refer to Figure 1 , the routing of the drop cable can be as follows Figure 1 For the first household cable 201 in the wiring, please refer to Figure 1 The first drop cable 201 in the house, the first drop cable 201 can be directly pulled toward the user 300 by the two-division box body 106. When the first drop cable 201 crosses some users 300 and runs toward other users 300, in this case, the portion of the first drop cable 201 located above the crossed users 300 will fall toward the crossed users 300, which cannot meet the demand for vertical drop cable entry. Vertical entry means that the drop cable is led down from above the user in a direction perpendicular or approximately perpendicular to the user 300. Therefore, it is necessary to set a suspension wire between the distribution poles 400 for hanging the distribution wire and the drop cable, and enable the drop cable to be routed along the suspension wire to a side approximately perpendicular to the user 300 and vertically led down into the house (such as Figure 1 However, some distribution cables 107 are generally provided with power supply wires for power supply. When the suspension wires include metal wires, damage to the distribution cables will cause the metal wires to be charged, resulting in lower safety. In addition, in the use scenario where the distribution pole is overhead, it is difficult to set the grounding wire of the metal wire, which is difficult to meet the use requirements when the distribution pole is overhead. Among them, the overhead distribution pole refers to the setting mode in which the distribution pole is off the ground.

[0059] In this regard, the present application embodiment provides a suspension wire 1, please refer to Figure 3 and Figure 4 The suspension wire 1 provided in this embodiment includes a wire core 11.

[0060] For example, the wire core 11 includes a metal wire core, which may be an iron wire core, a copper wire core, etc., to ensure the structural strength and tensile strength of the wire core 11. For example, the metal wire core may include a single or multiple strands of sub-wire cores 111. Figure 5When the metal wire core includes multiple strands of sub-wire cores 111, the multiple strands of sub-wire cores 111 can be twisted together. For example, the wire core 11 can also be made by twisting two strands of sub-wire cores 111, or four strands of sub-wire cores 111, or five strands of sub-wire cores 111. This is not limited in this embodiment. Thus, through the above arrangement, multiple strands of sub-wire cores 111 are twisted together to form the wire core 11. In this way, the bending resistance and tensile strength of the wire core 11 can be enhanced, and the twisted multiple strands of sub-wire cores 111 are conducive to reducing the radial size of the wire core 11 to reduce the volume of the wire core 11.

[0061] In other implementations, a plurality of sub-cores 111 are arranged in parallel to form the core 11 , which can reduce the difficulty of designing the core 11 and improve production efficiency.

[0062] Or the wire core 11 includes a non-metallic wire core, which generally refers to a wire core 11 with insulation capability, so that the insulation of the wire core 11 can be enhanced, thereby preventing the wire core 11 from being charged, and the non-metallic wire core may include a single or multiple sub-wire cores 111, and the sub-wire cores 111 include at least one of a glass yarn wire core, an aramid wire core, and a fine fiber reinforced composite material wire core. When the non-metallic wire core includes multiple sub-wire cores 111, please refer to Figure 6 , multiple strands of sub-cores 111 can be twisted together, thus, through the above arrangement, multiple strands of sub-cores 111 are twisted together to form the core 11, so that the bending resistance and tensile strength of the core 11 can be enhanced, and the twisted multiple strands of sub-cores 111 are conducive to reducing the radial dimension of the core 11 to reduce the volume of the core 11. Accordingly, multiple strands of sub-cores can also be arranged in parallel, which is not limited here. Accordingly, multiple strands of sub-cores 111 can also be arranged in parallel to form the core 11, so that it is easy to reduce the design difficulty of the core 11 and help improve production efficiency.

[0063] It is understandable that the non-metallic wire core has a certain flexibility compared to the metal steel stranded wire, and the non-metallic wire core has good insulation performance, that is, even if the cable 200 is damaged, it will not cause the wire core 11 to be charged, thereby improving the safety of the suspension wire 1.

[0064] In an implementation in which the wire core 11 includes a non-metallic wire core, the wire core 11 includes at least one of a glass yarn wire core, an aramid wire core, and a fine fiber reinforced composite material wire core.

[0065] For example, the core 11 may include a glass yarn core made of glass yarn, or an aramid core made of aramid, or a fine fiber reinforced composite core made of fine fiber reinforced composite material, or a hybrid core made by mixing any two or three of the glass yarn core, aramid core and fine fiber reinforced composite core.

[0066] Therefore, it is possible to ensure that the wire core 11 has good insulation properties as well as good structural strength and is lighter in weight than metal wires, which is conducive to achieving a lightweight design of the wire core 11 .

[0067] In the implementation mode where the core 11 includes at least one of a glass yarn core, an aramid core, and a fine fiber reinforced composite material core, the core 11 also includes an adhesive, which is filled in the non-metallic core. By providing the adhesive to fill the gaps in the non-metallic core, the density of the non-metallic core is increased so that the non-metallic core forms a dense structure, thereby enhancing the tensile and bending resistance of the non-metallic core.

[0068] For example, when the non-metallic wire core includes a glass yarn core 11, multiple strands of the glass yarn core 11 can be twisted to a certain extent and then coated with adhesive or immersed in adhesive, so that the adhesive fills the gaps in the glass yarn core 11, thereby forming the glass yarn core 11 into a structurally dense reinforcement, and thus making the glass yarn core 11 have a certain tensile and bending resistance, thereby reducing the possibility of the suspension wire 1 being stretched thin during use.

[0069] Alternatively, when the non-metallic core includes an aramid core 11, or a fine fiber reinforced composite core 11, or any two or three of the above three cores 11, it can also be formed into a structurally dense reinforcement by twisting and coating with adhesive or immersing in adhesive, and the same technical effect can be achieved, which will not be repeated here.

[0070] Please continue to refer to Figure 3 and Figure 4 The suspension wire 1 further includes an insulating layer 12 , which is coated on the outer side of the wire core 11 .

[0071] It can be understood that the insulating layer 12 is an insulating structure made of insulating material. For example, the insulating layer 12 may be a tubular structure sleeved on the outside of the wire core 11, or the insulating layer 12 may be an insulating coating coated on the outside of the wire core 11, or the insulating layer 12 may be an insulating structure wound around the outside of the wire core 11. This embodiment does not limit this.

[0072] In this way, when the suspension wire 1 is used to hang cables, the insulation between the wire core 11 and the cable 200 can be achieved through the insulating layer 12. In this way, when the cable 200 is damaged, the insulating layer 12 can prevent the wire core 11 from being charged. That is to say, even if the cable 200 is damaged, it will not cause the wire core 11 to be charged, thereby improving the safety of the suspension wire 1.

[0073] In the implementation mode in which the insulating layer 12 is coated on the outer side of the wire core 11, the insulating layer 12 includes at least one of a high-density polyethylene (HDPE) layer and a thermoplastic polyurethane (TPU) layer.

[0074] It is understandable that the material of the high-density polyethylene layer is high-density polyethylene, and the material of the thermoplastic polyurethane layer is thermoplastic polyurethane, wherein high-density polyethylene has good dielectric properties, heat resistance and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, and thermoplastic polyurethane has excellent electrical insulation, mold resistance and ultraviolet stability. Such a configuration can ensure that the insulating layer 12 has good insulation performance and good structural stability.

[0075] For example, the insulating layer 12 may be a high-density polyethylene layer, or the insulating layer 12 may be a thermoplastic polyurethane layer, or the insulating layer 12 may be an insulating member made of a mixture of high-density polyethylene and thermoplastic polyurethane, or the insulating layer 12 may be a two-layer structure, and the two-layer structure is a high-density polyethylene layer and a thermoplastic polyurethane layer, wherein, when the insulating layer 12 is a two-layer structure, the high-density polyethylene layer is coated on the outside of the core 11, and the thermoplastic polyurethane layer is coated on the side of the high-density polyethylene layer facing away from the core 11, or the thermoplastic polyurethane layer is coated on the outside of the core 11, and the high-density polyethylene layer is coated on the side of the thermoplastic polyurethane layer facing away from the core 11, and this embodiment does not impose any restrictions on this.

[0076] Please continue to refer to Figure 3 and Figure 4 The suspension wire 1 also includes: a mounting portion 13.

[0077] The mounting portion 13 is located outside the insulating layer 12 and connected to the insulating layer 12 . The mounting portion 13 is configured to mount the cable 200 .

[0078] It is understandable that the mounting portion 13 and the insulating layer 12 may be an integral structure, so as to reduce the difficulty of manufacturing the mounting portion 13 and the insulating layer 12, or the mounting portion 13 and the insulating layer 12 may be a separate structure. The mounting portion 13 has the function of mounting the cable 200, for example, the mounting portion includes a mounting ring, a hook structure, etc., which can be used to hang the cable 200, and this embodiment does not limit this.

[0079] In this way, it is convenient to directly mount the cable 200 using the mounting portion 13, so that when the cable 200 is mounted using the suspension wire 1, there is no need to bundle the cable 200 with the wire core 11, which is convenient for reducing the operation steps when mounting the cable 200 and helps to reduce the difficulty of operation.

[0080] For example, in the implementation of applying the suspension wire to the communication system, the suspension wire can be connected between two adjacent distribution poles, and then the distribution cable and the service cable can be mounted on the mounting part. Since the insulation layer is coated on the outside of the wire core, the insulation layer can be used to achieve insulation between the wire core and the cable. In this way, when the cable is damaged, the insulation layer can prevent the wire core from being charged, that is, even if the cable is damaged, the wire core will not be charged, thereby improving the safety of the suspension wire. In particular, in the use scenario where the distribution pole is overhead, due to the setting of the insulation layer, the suspension wire does not need to be grounded, thereby reducing the difficulty of setting the suspension wire to meet the use requirements when the distribution pole is overhead.

[0081] At the same time, since the suspension wire has its own mounting part, the mounting part can be directly used to hang the distribution cable and the house cable, so that the distribution cable and the house cable do not need to be bundled together with the suspension wire, which helps to reduce the difficulty of hanging them.

[0082] Correspondingly, the two-division box body can be provided with a hook, or a mounting hole, or other structure that can be mounted with the mounting part, so that the two-division box body can also be mounted on the mounting part, so that the two-division box body does not need to be hung on the wiring pole, thereby reducing the difficulty of mounting the two-division box body.

[0083] The suspension wire 1 provided in this embodiment has an insulating layer 12 wrapped around the outside of the core 11, a mounting portion 13 located outside the insulating layer 12 and connected to the insulating layer 12, and the mounting portion 13 is configured to mount a cable. When in use, the cable 200 can be mounted on the mounting portion 13. Since the insulating layer 12 is wrapped around the outside of the core 11, when the mounting portion 13 mounts the cable 200, the insulation between the core 11 and the cable 200 can be achieved through the insulating layer 12. In this way, when the cable 200 is damaged, the insulating layer 12 can prevent the core 11 from being charged, that is, even if the cable 200 is damaged, it will not cause the core 11 to be charged, thereby improving the safety of the suspension wire 1. At the same time, when the mounting portion 13 is used to hang the cable 200, it is not necessary to bundle the two together, which is conducive to reducing the difficulty of hanging.

[0084] In the implementation mode in which the mounting portion 13 and the insulating layer 12 are separate structures, the mounting portion 13 is rotatably connected to the insulating layer 12, please refer to Figure 7 , the rotation axis L3 of the mounting portion 13 (at Figure 7 The center line L1 of the core 11 (extending in the vertical direction) is Figure 4 The center extends vertically in the left-right direction.

[0085] It can be understood that the mounting portion 13 can rotate relative to the insulating layer 12, that is, the mounting portion 13 and the insulating layer 12 are separate structures. In this way, the mounting portion 13 can be selected according to actual usage requirements, and different types of mounting portions 13 can be designed separately, thereby enhancing the practicality of the mounting portion 13.

[0086] In the above implementation, the mounting portion 13 is rotatably connected to the insulating layer 12, so that the relative angle between the mounting portion 13 and the wire core 11 can be changed by rotating the mounting portion 13, so that the mounting portion 13 can mount the cable 200 extending in different directions, thereby facilitating the construction and cable threading operation.

[0087] In the implementation mode in which the mounting portion 13 is rotatably connected to the insulating layer 12, one of the insulating layer 12 and the mounting portion 13 is provided with a groove 121 and the other is provided with a connecting protrusion 135, and the connecting protrusion 135 is rotatably arranged in the groove 121. For example, the insulating layer 12 is provided with a connecting protrusion 135, and the mounting portion 13 is provided with a groove 121, or Figure 7 The insulating layer 12 is provided with a groove 121, and the mounting portion 13 is provided with a connecting protrusion 135. Such a configuration enables the mounting portion 13 and the insulating layer 12 to be rotatably connected, and the connection method is relatively simple, which helps to reduce the difficulty of manufacturing.

[0088] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the mounting portion 13 includes a mounting ring 131 , and the mounting ring 131 defines a cable threading space 1311 for the cable 200 to pass through.

[0089] Therefore, during construction, the cable 200 can be directly passed through the mounting ring 131 without the need to bundle the two together. After the cable 200 is passed through the cable threading space 1311, the mounting ring 131 can suspend the cable 200, and the mounting ring 131 is a circumferentially sealed annular structure, so that the mounting ring 131 can limit the cable 200 on the circumferential outer side of the cable 200, so as to prevent the cable 200 from detaching from the mounting ring 131, thereby ensuring the mounting stability of the cable 200 by the mounting ring 131.

[0090] In an implementation in which the mounting portion 13 includes a mounting ring 131 , on a horizontal plane, a projection of the center line L1 of the wire core 11 falls on the center line L2 of the cable threading space 1311 .

[0091] It is understandable that the horizontal plane refers to a plane perpendicular to the direction of gravity. In this way, after the cable 200 is passed through the cable passing space 1311, the extension direction of the cable 200 will be roughly parallel to the extension direction of the center line L1 of the wire core 11, thereby ensuring that the cable 200 can be routed roughly along the center line direction of the suspension wire 1 to meet the routing requirements of the cable 200.

[0092] Please refer to Figure 8 and Fig. 9 The mounting ring 131 is provided with an opening 1312 communicating with the cable threading space 1311 , one end of the opening 1312 is communicated with the cable threading space 1311 and the other end is open to the outside.

[0093] Therefore, the cable 200 can be placed on the mounting ring 131 or taken out from the mounting ring 131 through the opening 1312 , so as to reduce the difficulty of mounting and taking out the cable 200 .

[0094] In an implementation in which the mounting ring 131 is provided with an opening 1312 , a distance between the opening 1312 and a highest point of the mounting ring 131 is smaller than a distance between the opening 1312 and a lowest point of the mounting ring 131 .

[0095] Thus, at least a portion of the opening 1312 is located above the center line of the mounting ring 131 , thus preventing the cable 200 from being separated from the mounting ring 131 at the opening 1312 , thereby ensuring the mounting stability of the cable 200 .

[0096] Please refer to Fig.10 and Fig.11 In other implementations, the mounting portion 13 includes a connecting rod 133 and a hook 134 , the connecting rod 133 is connected between the insulating layer 12 and the hook 134 , and the hook 134 is used to mount the cable 200 .

[0097] Thus, the mounting portion 13 is formed into a hook structure including a connecting rod 133 and a hook head 134, so that the cable 200 can be mounted better, and the structure of the hook is simpler, which is conducive to reducing costs.

[0098] Please refer to Figure 4 , Fig. 9 , Fig.11 and Fig.12 The mounting parts 13 are provided with a plurality of mounting parts 13, and the plurality of mounting parts 13 are arranged at intervals along a direction parallel to the center line of the wire core 11. In this way, the pressure of the cable 200 can be dispersed through the plurality of mounting parts 13 to reduce the force of a single mounting part 13.

[0099] In the implementation mode of setting multiple mounting parts 13 in a direction parallel to the center line of the wire core 11, the distance between two adjacent mounting parts 13 is in the range of 0.5m-0.8m. For example, the distance between two adjacent mounting parts 13 can be 0.5m, or 0.6m, or 0.7m, or 0.8m, etc., that is, when the distance between two adjacent mounting parts 13 is within the above value range, the distribution of the mounting parts 13 can be more balanced, and the pressure of the cable 200 can be dispersed by multiple mounting parts 13 to reduce the force of a single mounting part 13, thereby enhancing the mounting capacity of the mounting part 13.
