Description

Technical Field

[0001] This invention relates to the field of optoelectronic composite cable technology, and in particular to a tensile-resistant optoelectronic component. Background Technology

[0002] Optical-optical composite cable assemblies are transmission lines suitable for broadband access network systems. As a new type of access method, they integrate optical fiber and power transmission lines, and can solve problems related to broadband access, equipment power supply, and signal transmission.

[0003] Patent CN219759261U discloses an optoelectronic composite cable assembly, including an insulating outer sheath, an optical fiber assembly, tensile wires, and a conductor assembly. The optical fiber assembly is embedded in the center of the insulating outer sheath, and tensile wires are embedded in a ring array on the insulating outer sheath of the outer ring of the optical fiber assembly.

[0004] The optical fiber component in the aforementioned optical-electric composite cable assembly has a certain tensile force inside the entire cable. However, the conductor component is locked in the spiral groove. Although it is easy to remove, its tensile strength and connectivity are poor, and it is prone to problems such as being pulled apart or detached. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a tensile-resistant optoelectronic component, the specific technical solution of which is as follows:

[0006] A tensile-resistant optoelectronic component includes a protective layer, an optical fiber component and multiple conductor components arranged along the length of the inner side of the protective layer, the optical fiber component being located at the center of the inner side of the protective layer, and the multiple conductor components arranged in a ring array on the outer side of the optical fiber component. Each conductor component includes an inner tube sleeve, on which multiple tensile-resistant portions are arranged in a ring array. Each tensile-resistant portion includes a strip block fixedly connected to the outer side of the inner tube sleeve along its length. The side of the strip block away from the inner tube sleeve has an insertion frame, and elastic blocks are fixedly connected to both sides of the inner wall of the insertion frame, with a gap formed between the opposite ends of two elastic blocks. A conductor body passing through the gap is spirally wound on the inner tube sleeve. A limiting portion is provided between the side of each conductor component away from the optical fiber component and the inner side of the protective layer. One side of one of the tensile-resistant portions on the inner tube sleeve is inserted into the outer side of the optical fiber component, and one side of the remaining tensile-resistant portions is inserted into the limiting portion.

[0007] As an improvement to the above technical solution: the number of the conductor assembly is set to three, and a filling layer is provided between each pair of adjacent conductor assemblies and optical fiber assemblies. The filling layer is arranged along the length direction of the protective layer and is arranged in a convex shape.

[0008] As an improvement to the above technical solution: the protective layer includes a shielding layer, an outer protective layer is fixedly connected to the outside of the shielding layer, the conductor includes a first insulating sleeve, a conductor core is disposed inside the first insulating sleeve, the optical fiber assembly includes an outer sheath, a second insulating sleeve is fixedly connected to the inner side of the outer sheath, and an optical fiber core is disposed inside the second insulating sleeve.

[0009] As an improvement to the above technical solution: the number of tensile parts is set to three groups, the insert frame is arranged in a U-shape, and the opposite end faces of the two elastic blocks are arranged in an arc shape. When the conductor is wound around the outer surface of the inner tube, one end of the conductor passes through the gaps in the inner sides of multiple insert frames in sequence.

[0010] As an improvement to the above technical solution: the limiting part includes an arc-shaped limiting sleeve inserted into the inner side of the protective layer. Both ends of the inner wall of the arc-shaped limiting sleeve are provided with limiting grooves that match the insertion frame. The limiting grooves are arranged along the length direction of the arc-shaped limiting sleeve. The two insertion frames in the wire assembly are inserted into the limiting grooves.

[0011] As an improvement to the above technical solution: the outer side of the inner tube sleeve is provided with a number of first slots corresponding to the insertion frame and a number of second slots corresponding to the insertion frame. The inner side of the first slot is fixedly connected with an elastic sleeve that matches the insertion frame. One end of part of the insertion frame is inserted into the inside of the elastic sleeve, and the rest of the insertion frame is inserted into the second slot.

[0012] As an improvement to the above technical solution: a magnet is fixedly connected to the bottom of the second slot, and the insertion frame is made of iron.

[0013] As an improvement to the above technical solution: both ends of the inner tube sleeve are provided with hook-shaped end holes, one end of which is located at the center of the end face of the inner tube sleeve, and the other end of which extends to the outer side of the inner tube sleeve.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The conductors spirally wound around the inner tube provide a certain tensile strength. The elastic blocks on multiple insert frames distribute the force evenly on the conductors when they are pulled, giving them good tensile strength. One end of each conductor assembly is inserted into the outer side of the fiber optic assembly through the insert frames, while the other two ends are limited in the upper groove of the arc-shaped limiting sleeve through the insert frames. The fiber optic assembly is connected to the second slot through multiple insert frames on its three outer ends, and multiple insert frames are inserted into the inner side of the elastic sleeve, allowing the fiber optic assembly to be evenly subjected to tensile force. Multiple filling layers fill the inside of the protective layer, so that the conductor and fiber optic assemblies are not only stably connected by the multiple insert frames, but also supported by the filling layers. This ensures that the conductor and fiber optic assemblies are stably connected inside the protective layer while also having good resistance.

[0016] 2. When it is necessary to remove the wire assembly, simply pull out the arc-shaped limiting sleeve connected to the wire assembly to the outside of the protective layer, and then pull the wire assembly away from the fiber optic assembly to disengage the insertion frame from the first and second slots. Then, pull the wire assembly out from the protective layer. Thus, this application allows for easy removal of the wire assembly from the protective layer while maintaining the stability and resistance of the wire assembly connected internally.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0023] A tensile-resistant optoelectronic component, please refer to Figures 1-4 It includes a protective layer 1, and an optical fiber assembly 3 and multiple conductor assemblies 2 are arranged along the length direction inside the protective layer 1. The optical fiber assembly 3 is located at the center inside the protective layer 1, and multiple conductor assemblies 2 are arranged in a ring array outside the optical fiber assembly 3. The conductor assembly 2 includes an inner tube sleeve 20, and multiple tensile parts are arranged in a ring array on the inner tube sleeve 20.

[0024] The tensile part includes a strip 23 fixedly connected to the outer side of the inner tube sleeve 20 along its length. The side of the strip 23 away from the inner tube sleeve 20 has a frame 22. Both sides of the inner wall of the frame 22 are fixedly connected to elastic blocks 25, and a gap is formed between the opposite ends of the two elastic blocks 25. A conductor 21 passing through the gap is spirally wound on the inner tube sleeve 20. A limiting part is provided between the side of each conductor assembly 2 away from the optical fiber assembly 3 and the inner side of the protective layer 1. The limiting part is arranged along the length direction inside the protective layer 1. One side of the tensile part on the inner tube sleeve 20 is inserted into the outer side of the optical fiber assembly 3, and the other side of the tensile part is inserted into the limiting part.

[0025] In an optional embodiment: the number of conductor assemblies 2 is set to three, and a filling layer 5 is provided between each pair of adjacent conductor assemblies 2 and optical fiber assemblies 3. The filling layer 5 is arranged along the length direction of the protective layer 1 and is arranged in a convex shape. Specifically, the filling layer 5 can be composed of tensile fibers formed of aromatic polyamide fibers or other existing filling materials that can support the optical fiber assemblies 3 and conductor assemblies 2.

[0026] like Figure 1 As shown, the number of filling layers 5 is set to three. The outer side of the filling layer 5 matches the inner side of the protective layer 1, the end side of the limiting part, the outer side of the conductor assembly 2, and the outer side of the optical fiber assembly 3, respectively, thus forming a convex-shaped arrangement. In this way, the limiting part, conductor assembly 2 and optical fiber assembly 3 can be more stably limited to the inner side of the protective layer 1 by multiple filling layers 5.

[0027] In an optional embodiment: the protective layer 1 includes a shielding layer 11, an outer protective layer 12 is fixedly connected to the outside of the shielding layer 11, the conductor body 21 includes a first insulating sleeve 211, a conductor core 212 is disposed inside the first insulating sleeve 211, the optical fiber assembly 3 includes an outer sheath 31, a second insulating sleeve 32 is fixedly connected to the inside of the outer sheath 31, and an optical fiber core 33 is disposed inside the second insulating sleeve 32, and the conductor assembly 2 and the optical fiber assembly 3 inside the protective layer 1 are shielded by the shielding layer 11.

[0028] In an optional embodiment, the number of tensile parts is set to three groups. The tensile parts include strips 23 fixedly connected to the outer side of the inner tube sleeve 20 along its length. The side of the strip 23 away from the inner tube sleeve 20 has multiple U-shaped insert frames 22. Both sides of the inner wall of the insert frame 22 are fixedly connected to elastic blocks 25. The opposite end faces of the two elastic blocks 25 are arc-shaped, and a gap is formed between the opposite ends of the two elastic blocks 25. When the conductor 21 is wound around the outer surface of the inner tube sleeve 20, one end of the conductor 21 passes through the gap in the inner side of the multiple insert frames 22 in sequence. The conductor 21, which is spirally wound on the inner tube sleeve 20, provides a certain tensile strength. The elastic blocks 25 on the multiple insert frames 22 evenly apply force to the conductor 21 when it is pulled, so that the conductor 21 has good tensile strength.

[0029] In an optional embodiment: the limiting part includes an arc-shaped limiting sleeve 4 inserted into the inner side of the protective layer 1. Both ends of the inner wall of the arc-shaped limiting sleeve 4 are provided with limiting grooves 41 that match the insert frame 22. The limiting grooves 41 are arranged along the length direction of the arc-shaped limiting sleeve 4. The two insert frames 22 in the wire assembly 2 are inserted into the limiting grooves 41.

[0030] In an optional embodiment: the outer side of the inner tube sleeve 20 is provided with a plurality of first slots 201 corresponding to the insertion frame 22 and a plurality of second slots 202 corresponding to the insertion frame 22. The inner side of the first slot 201 is fixedly connected with an elastic sleeve 26 matching the insertion frame 22. One end of some insertion frames 22 is inserted into the inside of the elastic sleeve 26, and the remaining insertion frames 22 are inserted into the second slots 202. Specifically, the plurality of first slots 201 and second slots 202 are divided into three groups, and the three groups are evenly arranged at three locations on the outer side of the inner tube sleeve 20. The first slots 201 and second slots 202 of each group are arranged together at intervals. By inserting the insertion frame 22 into the wire assembly 2 of the second slot 202, the multi-wire assembly 2 and the optical fiber assembly 3 can be stably connected together. By inserting the insertion frame 22 into the first slot 201, the overall tensile strength of the optical fiber assembly 3 is improved.

[0031] In an optional embodiment: a magnet 27 is fixedly connected to the bottom of the second slot 202, and the insert frame 22 is made of iron. When the insert frame 22 is inserted into the second slot 202, one end of the insert frame 22 can be attracted to the magnet 27, which allows the optical fiber assembly 3 to be connected to multiple wire assemblies 2 more stably.

[0032] In an optional embodiment: both ends of the inner tube sleeve 20 are provided with hook-shaped end holes 200. One end of the end hole 200 is located at the center of the end face of the inner tube sleeve 20, and the other end of the end hole 200 extends to the outer side of the inner tube sleeve 20. When the conductor 21 is wound around the inner tube sleeve 20, one end of the conductor 21 will first pass through one end hole 200, and after the winding is completed, it will pass through the other end hole 200, so that both ends of the conductor 21 are limited to the center of both ends of the inner tube sleeve 20. This allows the conductor 21 to be stably limited on the inner tube sleeve 20, and further improves the tensile strength of the conductor 21.

[0033] Specifically, when using the optoelectronic components of this application, the conductor 21 spirally wound on the inner tube sleeve 20 provides a certain tensile strength. The elastic blocks 25 on the multiple insertion frames 22 evenly apply force to the conductor 21 when it is pulled, so that the conductor 21 has good tensile strength. One side of the multiple conductor components 2 is inserted into the outer side of the optical fiber component 3 through the insertion frame 22, and the other two sides are limited in the upper limit groove 41 of the arc-shaped limiting sleeve 4 through the insertion frame 22. The optical fiber component 3 is connected to the second slot 202 through the insertion of the multiple insertion frames 22 on the outer three ends and to the inner side of the elastic sleeve 26 through the insertion of the multiple insertion frames 22, so that the optical fiber component 3 is evenly subjected to tensile force. Then, multiple filling layers 5 are filled inside the protective layer 1, so that the multiple conductor components 2 and optical fiber components 3 are not only subjected to the stable connection force of the multiple insertion frames 22, but also to the support force of the filling layer 5, so that the multiple conductor components 2 and optical fiber components 3 are stably connected inside the protective layer 1 while having good resistance.

[0034] When it is necessary to remove the wire assembly 2, simply pull the arc-shaped limiting sleeve 4 connected to the wire assembly 2 outward to the outside of the protective layer 1, and then pull the wire assembly 2 away from the fiber optic assembly 3 so that the insertion frame 22 disengages from the first slot 201 and the second slot 202. Then, the wire assembly 2 can be pulled out from the protective layer 1. Thus, this application facilitates the removal of the wire assembly 2 from the protective layer 1 while maintaining the stability and resistance of the wire assembly 2 connected internally.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
