Description

Drop wire and drop wire assembly

[0001] The present application claims priority to the Chinese patent application No. 202420763253.3, filed on April 12, 2024, and entitled "Drop wire and drop wire assembly", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the technical field of drop wires, in particular to a drop wire and a drop wire assembly. BACKGROUND

[0003] The cables are usually connected between adjacent distribution poles, and need to be suspended by a drop wire. However, the cables generally have a power supply wire for power supply, and the drop wire is mostly a metal wire. In actual use, the breakage of the cable can cause the drop wire to be electrified, resulting in low safety. SUMMARY

[0004] Embodiments of the present application provide a drop wire and a drop wire assembly, aiming to solve the problem of low safety caused by the electrification of the drop wire due to the breakage of the cable.

[0006] The drop wire provided by the embodiments has the insulation layer wrapped on the outer side of the wire core, and the mounting part is located on the outer side of the insulation layer and connected with the insulation layer. Therefore, the cable can be mounted on the mounting part. Since the insulation layer is wrapped on the outer side of the wire core, the insulation between the wire core and the cable can be achieved by the insulation layer when the mounting part mounts the cable. In this way, when the cable is broken, the insulation layer can prevent the wire core from being electrified. That is, even if the cable is broken, the wire core will not be electrified, thereby improving the safety of the drop wire.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0052] The embodiment of the present application provides a hanging wire assembly, the hanging wire assembly comprises a hanging wire and a cable, the hanging wire assembly can be applied to a power system or a communication system, and the cable can comprise an optical cable or a wire. The power system and the communication system both comprise a plurality of distribution poles, each of which is arranged on the ground; the hanging wire is hung on each distribution pole, and the cable is hung on the hanging wire to realize the fixation of the cable through the hanging wire. When the hanging wire assembly is applied to the power system, the cable comprises a wire and is used for transmitting power; when the hanging wire assembly is applied to the communication system, the cable comprises an optical cable and is used for transmitting signals.

[0053] In order to clearly express the structure of the hanging wire assembly provided by the present application, the application of the hanging wire assembly to the communication system is exemplified below. Referring to FIG. 1, the communication system comprises a machine room 100, a control device 102, an optical distribution box 104, a signal line 105, a joint 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 distribution box 104, then the signal line 105 is branched from the optical distribution box 104 and led out to the joint box 103, and then led out from the joint box 103 to be connected to the outdoor cabinet 101, and the signal line 105 is branched from the optical distribution box 104 and led out to be connected to a two-way distribution box body 106 fixed on the distribution pole 400. Each distribution pole 400 is provided with the two-way distribution box body 106, and two adjacent two-way distribution box bodies 106 are connected through a distribution cable 107, then a household cable is pulled from the two-way distribution box body 106 to a user 300. In the machine room 100, a signal transceiver is usually arranged, the signal transceiver is connected to the signal line 105 to transmit or receive signals, the control device 102 is used for controlling whether the signal line 105 transmits signals, the optical distribution box 104 is used for the connection between the signal line 105 and the distribution cable 107, the outdoor cabinet 101 is generally provided with a computer and related control equipment and is used for monitoring whether the communication system can normally work, and the two-way distribution box body 106 is used for branching the distribution cable 107, so that the distribution cable 107 can branch the household cable.

[0054] It can be understood that, in the embodiment of the present application, the cable can comprise a distribution cable and / or a household cable. Exemplarily, the distribution cable and the household cable can comprise an optical cable or a wire for transmitting signals.

[0055] In the above implementation, the distribution cable includes an optical cable, and the distribution cable can include an all-dielectric self supporting (ADSS) optical cable. Referring to FIG. 2, the all-dielectric self supporting optical cable 500 includes a plurality of sub optical cables, a plurality of the sub optical cables can be wrapped in a fiber and a filler 504 to form an optical cable bundle, an outer side of the optical cable bundle is provided with a loose tube 503, and the optical cable bundle can be provided with a plurality of optical cable bundles, the plurality of optical cable bundles are twistedly arranged on an outer side of a steel core 505, a water-blocking yarn 506 is arranged between two adjacent optical cable bundles and the steel core 505, and the optical cable bundle and the steel core 505 can be wrapped in a water-blocking tape 507, an outer side of the water-blocking tape 507 can be wrapped with aramid yarn 502, an outer side of the aramid yarn 502 can be wound with an umbrella opening cable 508, and an outer side of the aramid yarn 502 can be wrapped 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 wrapped on an outer side of the optical fiber. For example, the sub optical cable can be connected to the drop cable through the two-part box body to realize the connection between the drop cable and the distribution cable.

[0056] Please continue to refer to FIG. 1, the routing mode of the drop cable can be as shown in the first drop cable 201 in FIG. 1. Please refer to the first drop cable 201 in FIG. 1, the first drop cable 201 can be directly pulled to the user 300 by the two-part box body 106. When the first drop cable 201 routes to other users 300 across some users 300, in this case, the part of the first drop cable 201 above the crossed users 300 will fall towards the crossed users 300, which cannot meet the demand of the drop cable vertically entering the house. The vertically entering the house means that the drop cable is introduced into the house from above the user 300 in a direction perpendicular or approximately perpendicular to the user 300. Therefore, a hanging line needs to be arranged between the distribution poles 400 to suspend the distribution cable and the drop cable, and the drop cable can be routed along the hanging line to be introduced into the house in a direction approximately perpendicular to the side of the user 300 (such as the routing mode of the second drop cable 202 in FIG. 1). However, the power supply line for power supply is generally arranged in the distribution cable 107. In the case that the hanging line includes a metal wire, the damage of the distribution cable will cause the metal wire to be electrified, which results in low safety. Moreover, in the use scenario of the overhead distribution pole, it is difficult to arrange the grounding wire of the metal wire, which cannot meet the use demand of the overhead distribution pole. The overhead distribution pole means that the distribution pole is arranged away from the ground.

[0057] To solve the above problems, the embodiment of the present application provides a hanging line 1. Please refer to FIG. 3 and FIG. 4, the hanging line 1 provided by the embodiment includes a wire core 11.

[0058] For example, the wire core 11 includes a metal wire core, which can 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 can include a single or multiple sub-wire cores 111. Referring to FIG. 5, when the metal wire core includes multiple sub-wire cores 111, the multiple sub-wire cores 111 can be twisted. For example, the wire core 11 can be made of two twisted sub-wire cores 111, or four twisted sub-wire cores 111, or five twisted sub-wire cores 111. The present embodiment does not limit this. Thus, the multiple sub-wire cores 111 are twisted to form the wire core 11, which can enhance the bending resistance and tensile strength of the wire core 11. The twisted multiple sub-wire cores 111 can reduce the radial dimension of the wire core 11 to reduce the volume of the wire core 11.

[0059] In other implementations, the multiple sub-wire cores 111 are arranged in parallel to form the wire core 11, which can reduce the design difficulty of the wire core 11 and improve the production efficiency.

[0060] Alternatively, the wire core 11 includes a non-metal wire core, which generally refers to a wire core 11 having insulation capability, which can enhance the insulation of the wire core 11 to avoid electrification of the wire core 11. The non-metal wire core can include a single or multiple sub-wire cores 111, which include at least one of a glass yarn core, an aramid fiber core, and a fine fiber reinforced composite material core. Referring to FIG. 6, when the non-metal wire core includes multiple sub-wire cores 111, the multiple sub-wire cores 111 can be twisted. Thus, the multiple sub-wire cores 111 are twisted to form the wire core 11, which can enhance the bending resistance and tensile strength of the wire core 11. The twisted multiple sub-wire cores 111 can reduce the radial dimension of the wire core 11 to reduce the volume of the wire core 11. Alternatively, the multiple sub-wire cores can be arranged in parallel, which is not limited herein. Alternatively, the multiple sub-wire cores 111 can be arranged in parallel to form the wire core 11, which can reduce the design difficulty of the wire core 11 and improve the production efficiency.

[0061] It can be understood that the non-metal wire core has a certain flexibility relative to the metal steel strand, and the non-metal wire core has good insulation performance, that is, even if the cable 200 is damaged, the wire core 11 will not be electrified, thereby improving the safety of the wire 1.

[0062] In the implementation where the wire core 11 includes a non-metal wire core, the wire core 11 includes at least one of a glass yarn core, an aramid fiber core, and a fine fiber reinforced composite material core.

[0063] For example, the wire core 11 can include a glass yarn wire core made of glass yarn, or an aramid wire core made of aramid, or a fine fiber reinforced composite wire core made of fine fiber reinforced composite, or a mixed wire core made of any two or three of the glass yarn wire core, the aramid wire core and the fine fiber reinforced composite wire core.

[0064] In this way, the wire core 11 can be guaranteed to have good insulation while having good structural strength and being lighter in weight than metal wires, which is conducive to the lightweight design of the wire core 11.

[0065] In the implementation in which the wire core 11 includes at least one of the glass yarn wire core, the aramid wire core and the fine fiber reinforced composite wire core, the wire core 11 further includes an adhesive filled in the non-metal wire core. By providing the adhesive, the gaps in the non-metal wire core are filled, and the density of the non-metal wire core is enhanced so that the non-metal wire core forms a dense structure, and the tensile and bending resistance of the non-metal wire core is enhanced.

[0066] For example, when the non-metal wire core includes the glass yarn wire core 11, a plurality of strands of the glass yarn wire core 11 can be twisted and then coated with adhesive or immersed in adhesive, so that the adhesive fills the gaps in the glass yarn wire core 11, and the glass yarn wire core 11 forms a dense structure, and the glass yarn wire core 11 has certain tensile and bending resistance, and the possibility of the hanging wire 1 being thinned during use is reduced.

[0067] Or when the non-metal wire core includes the aramid wire core 11, or the fine fiber reinforced composite wire core 11, or any two or three of the above three wire cores 11, the twisting and coating with adhesive or immersion in adhesive can also be used to form a dense structure, and the same technical effects can be achieved, which will not be described here.

[0068] Please continue to refer to FIGS. 3 and 4, the hanging wire 1 further includes: an insulation layer 12, the insulation layer 12 is wrapped on the outside of the wire core 11.

[0069] It can be understood that the insulation layer 12 is an insulation structure made of insulating material, for example, the insulation layer 12 can be a tubular structure wrapped on the outside of the wire core 11, or the insulation layer 12 can be an insulating coating coated on the outside of the wire core 11, or the insulation layer 12 can be an insulating structure wrapped on the outside of the wire core 11, and the present embodiment does not limit this.

[0070] In this way, when the hanging wire 1 is used to mount the cable, the insulation between the wire core 11 and the cable 200 can be achieved by the insulation layer 12, so that when the cable 200 is damaged, the insulation layer 12 can prevent the wire core 11 from being electrified, that is, even if the cable 200 is damaged, the wire core 11 will not be electrified, and the safety of the hanging wire 1 is improved.

[0071] 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 comprises at least one of a high density polyethylene (HDPE) layer and a thermoplastic polyurethane (TPU) layer.

[0072] It can be understood that the material of the high density polyethylene layer is high density polyethylene, and the material of the thermoplastic polyurethane layer is thermoplastic polyurethane. The high density polyethylene has good dielectricity, heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. The thermoplastic polyurethane has excellent electrical insulation, mold resistance and ultraviolet stability. In this way, the insulating layer 12 has good insulation performance and good structural stability.

[0073] For example, the insulating layer 12 can be a high density polyethylene layer, or the insulating layer 12 can be a thermoplastic polyurethane layer, or the insulating layer 12 can be an insulating piece made of a mixture of high density polyethylene and thermoplastic polyurethane, or the insulating layer 12 can have a two-layer structure, and the two layers are a high density polyethylene layer and a thermoplastic polyurethane layer. When the insulating layer 12 has a two-layer structure, the high density polyethylene layer is coated on the outer side of the wire core 11, and the thermoplastic polyurethane layer is coated on the side of the high density polyethylene layer away from the wire core 11, or the thermoplastic polyurethane layer is coated on the outer side of the wire core 11, and the high density polyethylene layer is coated on the side of the thermoplastic polyurethane layer away from the wire core 11. The present embodiment does not limit this.

[0074] Please continue to refer to FIGS. 3 and 4, the hanging wire 1 further comprises a mounting part 13.

[0075] The mounting part 13 is located on the outer side of the insulating layer 12 and connected with the insulating layer 12. The mounting part 13 is configured to mount the cable 200.

[0076] It can be understood that the mounting part 13 can be an integral structure with the insulating layer 12, so as to reduce the manufacturing difficulty of the mounting part 13 and the insulating layer 12, or the mounting part 13 can be a separate structure with the insulating layer 12. The mounting part 13 has the function of mounting the cable 200, for example, the mounting part comprises a mounting ring or a hook structure which can be used to hang the cable 200. The present embodiment does not limit this.

[0077] In this way, the mounting of the cable 200 can be directly realized by using the mounting part 13, so that when the cable 200 is mounted by using the hanging wire 1, the cable 200 does not need to be bound with the wire core 11, the operation steps when the cable 200 is mounted are reduced, and the operation difficulty is reduced.

[0078] For example, in the implementation of applying the hanging line to the communication system, the hanging line can be connected between two adjacent distribution poles, and then the distribution cable and the home cable can be hung on the hanging part. Since the insulating layer is wrapped outside the wire core, the insulation between the wire core and the cable can be realized through the insulating layer. In this way, when the cable is damaged, the insulating layer can prevent the wire core from being electrified. That is, even if the cable is damaged, the wire core will not be electrified, thereby improving the safety of the hanging line. Especially in the use scenario of overhead distribution poles, due to the setting of the insulating layer, the hanging line does not need to be grounded, thereby facilitating the reduction of the setting difficulty of the hanging line to meet the use requirement when the distribution pole is overhead.

[0079] At the same time, since the hanging line is provided with the hanging part, the hanging of the distribution cable and the home cable can be directly realized by using the hanging part, so that the distribution cable and the home cable do not need to be bundled together with the hanging line, which is beneficial to reduce the hanging difficulty.

[0080] Correspondingly, the two-part box body can be provided with a hook, or a hanging hole, or other structures capable of being hung with the hanging part. In this way, the two-part box body can also be hung on the hanging part, so that the two-part box body does not need to be hung on the distribution pole, thereby facilitating the reduction of the hanging difficulty of the two-part box body.

[0081] The hanging line 1 provided in the embodiment is provided with an insulating layer 12 wrapped outside the wire core 11, a hanging part 13 located outside the insulating layer 12 and connected with the insulating layer 12, and the hanging part 13 is configured to hang the cable. In use, the cable 200 can be hung on the hanging part 13. Since the insulating layer 12 is wrapped outside the wire core 11, when the hanging part 13 hangs the cable 200, the insulation between the wire core 11 and the cable 200 can be realized 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 electrified. That is, even if the cable 200 is damaged, the wire core 11 will not be electrified, thereby improving the safety of the hanging line 1. At the same time, when the cable 200 is hung by using the hanging part 13, the two do not need to be bundled together, which is beneficial to reduce the hanging difficulty.

[0082] In the implementation mode that the hanging part 13 and the insulating layer 12 are in a split structure, the hanging part 13 is rotatably connected with the insulating layer 12. Please refer to FIG. 7. The rotation axis L3 (extending in the up-down direction in FIG. 7) of the hanging part 13 is perpendicular to the center line L1 (extending in the left-right direction in FIG. 4) of the wire core 11.

[0083] It can be understood that the hanging part 13 can rotate relative to the insulating layer 12, that is, the hanging part 13 and the insulating layer 12 are in a split structure. In this way, the hanging part 13 can be selected according to the actual use requirement, and different types of hanging parts 13 can be designed separately, thereby enhancing the practicability of the hanging part 13.

[0084] 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 operation of the construction cable.

[0085] In the implementation 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 rotatably arranged in the groove 121. For example, the insulating layer 12 is provided with the connecting protrusion 135, and the mounting portion 13 is provided with the groove 121, or referring to FIG. 7, the insulating layer 12 is provided with the groove 121, and the mounting portion 13 is provided with the connecting protrusion 135. In this way, the mounting portion 13 and the insulating layer 12 can be rotatably connected, and the connection mode is relatively simple, which is beneficial to reduce the manufacturing difficulty.

[0086] Please continue to refer to FIGS. 3 and 4, in some embodiments, the mounting portion 13 includes a mounting ring 131, and the mounting ring 131 surrounds a cable passing space 1311 for the cable 200 to pass through.

[0087] 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 passing space 1311, the mounting ring 131 can suspend the cable 200, and the mounting ring 131 is a circumferentially sealed circular structure, so that the mounting ring 131 can limit the cable 200 on the outer side of the cable 200 in the circumferential direction, to avoid the cable 200 from separating from the mounting ring 131, thereby ensuring the mounting stability of the mounting ring 131 to the cable 200.

[0088] In the implementation in which the mounting portion 13 includes the mounting ring 131, the projection of the center line L1 of the wire core 11 falls on the center line L2 of the cable passing space 1311 in the horizontal plane.

[0089] It can be understood 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 substantially parallel to the extension direction of the center line L1 of the wire core 11, thereby ensuring that the cable 200 can be routed substantially along the center line direction of the wire 1, to meet the routing requirements of the cable 200.

[0090] Please refer to FIGS. 8 and 9, the mounting ring 131 is provided with an opening 1312 communicating with the cable passing space 1311, one end of the opening 1312 communicates with the cable passing space 1311 and the other end is open to the outside.

[0091] Therefore, the cable 200 can be placed onto or taken off from the mounting ring 131 through the opening 1312, so as to reduce the mounting and taking-off difficulty of the cable 200.

[0092] In the implementation mode in which the mounting ring 131 is provided with the opening 1312, the distance between the opening 1312 and the highest point of the mounting ring 131 is less than the distance between the opening 1312 and the lowest point of the mounting ring 131.

[0093] Therefore, at least part of the opening 1312 is located above the center line of the mounting ring 131, so that the cable 200 can be prevented from being separated from the mounting ring 131 at the opening 1312, and the mounting stability of the cable 200 is ensured.

[0094] Please refer to FIG. 10 and FIG. 11, in other implementation modes, the mounting part 13 includes a connecting rod 133 and a hook head 134, the connecting rod 133 is connected between the insulating layer 12 and the hook head 134, and the hook head 134 is used for mounting the cable 200.

[0095] Therefore, the mounting part 13 is formed as a hook structure including the connecting rod 133 and the hook head 134, so that the cable 200 can be better mounted, and the structure of the hook is simpler, which is beneficial to reduce the cost.

[0096] Please refer to FIG. 4, FIG. 9, FIG. 11 and FIG. 12, the mounting part 13 is provided in plurality, and the plurality of mounting parts 13 are arranged in a direction parallel to the center line of the core 11. In this way, the pressure of the cable 200 can be dispersed by the plurality of mounting parts 13, so as to reduce the stress of a single mounting part 13.

[0097] In the implementation mode in which the plurality of mounting parts 13 are arranged in a direction parallel to the center line of the core 11, the distance between two adjacent mounting parts 13 is in the range of 0.5m-0.8m. Exemplarily, 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 in the above range, the distribution of the mounting parts 13 can be more balanced, and the pressure of the cable 200 can be dispersed by the plurality of mounting parts 13, so as to reduce the stress of a single mounting part 13, and the mounting capacity of the mounting part 13 can be enhanced.
