[0002] Plastic optical cable is a light-guiding medium consisting of a single-core or multi-core plastic optical fiber covered with a plastic sheath. In the field of modern communications and sensing, the demand for high-speed, low-cost and easy-to-install transmission solutions is growing, and plastic optical cable has been widely used in this context.

[0003] Because plastic optical cables can support high-speed data transmission, they are suitable for scenarios such as broadband access and smart networks in homes and offices.

[0004] Dual-core optical cables use dual-fiber bidirectional loops, with each fiber responsible for signal transmission in one direction. Although this method requires more optical fibers, it simplifies the configuration and maintenance of equipment, and provides higher reliability and stability due to its independent sending and receiving fibers. This type of optical cable is suitable for scenarios with high communication quality requirements, such as long-distance transmission and high-bandwidth applications.

[0005] The existing double-core plastic optical cable is difficult to meet the use requirements of long-distance transmission due to its tensile strength and impact resistance, so there is an urgent need for a double-core plastic optical cable with tensile strength. Summary of the invention

It has excellent heat resistance, flame retardancy and antistatic properties, and is widely used in many fields due to its low density, high strength, good toughness and high temperature resistance. Kevlar can withstand extremely high and extremely low temperatures, which makes it suitable for extreme environments, and is not easy to generate static electricity, and will not interfere with wireless signals, which makes it very advantageous for use in electronic devices. The Kevlar fiber layer of the present invention is between the two inner sheaths, and can also improve the tensile strength and impact resistance of the optical cable.

[0049] 2. The assembly jig of the present invention uses corresponding ridges and grooves in the upper mold and the lower mold to stamp out the clamping tailstock of the optical fiber connector to deform it, thereby clamping and fixing the plastic optical fiber inserted into the clamping tailstock and the optical fiber connector; and the stamping assembly of the assembly jig is automated production, which improves production efficiency while ensuring product consistency.

[0050] 3. When the assembly jig of the present invention is used to assemble optical cables and optical fiber connectors of different specifications, first replace the upper mold and the lower mold that are compatible with the clamping tailstock of the optical fiber connector; then, drive the optical fiber connector clamping tooling to adjust the height in the vertical direction through the lifting cylinder; then, drive the optical fiber connector clamping tooling to adjust the position in the horizontal direction through the screw mechanism, and the adaptation operation of the optical fiber connector and the jig is completed at this time; since the displacement clamping block and the floating clamping block of the clamping piece are floating clamped, it can also adapt to optical cables of different diameters; the assembly jig can assemble optical cables and optical fiber connectors of different specifications without adjustment, which greatly improves the scope of application of the assembly jig in actual production.

[0077] Embodiment 1

[0078] The present invention provides a tensile-resistant Kevlar dual-core plastic optical cable assembly, see Figure 1-4 , comprising an optical cable 1, an optical fiber connector 2 and a protective sleeve 3; the optical cable 1 is a dual-core optical cable, comprising two plastic optical fibers 100a, an inner sheath 100b that individually wraps the outside of the plastic optical fibers 100a, and an outer sheath 100c that simultaneously wraps the two plastic optical fibers 100; the optical fiber connector 2 is installed at one end of the optical cable 1 for connecting equipment to achieve data transmission; a clamping tailstock 200 is provided at the connection between the optical fiber connector 2 and the plastic optical fiber 100a, and the clamping tailstock 200 is deformed by stamping the clamping tailstock 200 with an external force, so that the plastic optical fiber 100a sleeved in the clamping tailstock 200 is clamped and fixed to the optical fiber connector 2; the protective sleeve 3 is sleeved on the outside of the optical fiber connector 2.

[0079] In some embodiments, Figure 3 As shown, a Kevlar fiber layer 100d is arranged in the gap between the two inner sheaths 100b. Kevlar aramid fiber material, its chemical name is poly(p-phenylene terephthalamide); Kevlar, as a high-performance composite material, has a strength five times that of steel of the same quality, but a density of only one-fifth of that of steel. It has excellent heat resistance, flame retardancy and antistatic properties, and is widely used in many fields due to its low density, high strength, good toughness and high temperature resistance. Kevlar can withstand extremely high and low temperatures, which makes it suitable for extreme environments, and is not prone to static electricity, and will not interfere with wireless signals, which makes it very advantageous for use in electronic devices. The Kevlar fiber layer 100d of the present invention is between the two inner sheaths 100b, and can also improve the tensile strength and impact resistance of the optical cable.

[0080] The Kevlar fiber layer 100d extends along the length direction on one side of the gap between the two inner sheaths 100b. When the two plastic optical fibers 100 wrapped in the circular inner sheaths 100b are arranged side by side, two triangular cavities are formed between the two circular inner sheaths 100b, and the Kevlar fiber layer 100d just utilizes one of the triangular cavities and extends synchronously with the plastic optical fiber 100 along the length direction, thereby improving the tensile strength and impact resistance of the overall optical cable.

[0081] In some embodiments, Figure 4 As shown, a Kevlar fiber layer 100d is arranged in the gap between the two inner sheaths 100b. Kevlar aramid fiber material, its chemical name is poly(p-phenylene terephthalamide); Kevlar, as a high-performance composite material, has a strength five times that of steel of the same quality, but a density of only one-fifth of that of steel. It has excellent heat resistance, flame retardancy and antistatic properties, and is widely used in many fields due to its low density, high strength, good toughness and high temperature resistance. Kevlar can withstand extremely high and low temperatures, which makes it suitable for extreme environments, and is not prone to static electricity, and will not interfere with wireless signals, which makes it very advantageous for use in electronic devices. The Kevlar fiber layer 100d of the present invention is between the two inner sheaths 100b, and can also improve the tensile strength and impact resistance of the optical cable.

[0082] The Kevlar fiber layer 100d extends along the length direction on both sides of the gap between the two inner sheaths 100b. When the two plastic optical fibers 100 wrapped in the circular inner sheaths 100b are arranged side by side, two triangular cavities are formed between the two circular inner sheaths 100b, and the Kevlar fiber layer 100d just utilizes the two triangular cavities and extends synchronously with the plastic optical fiber 100 along the length direction, thereby improving the tensile strength and impact resistance of the overall optical cable.

[0084] The present invention also provides an assembly jig for a tensile-resistant Kevlar dual-core plastic optical cable assembly, see Figure 5 and Figure 6 , including a vibration plate 10 for continuously conveying the optical fiber connector 2; an assembling mechanism 20 for respectively inserting the ends of the two plastic optical fibers 100a of the optical cable 1 into the wiring holes of the optical fiber connector 2; and a punching mechanism 30 for punching the clamping tail seat 200 of the optical fiber connector 2 to deform it, thereby clamping and fixing the plastic optical fiber 100a sleeved in the clamping tail seat 200 and the optical fiber connector 2.

[0085] Specifically, Figure 7-9As shown, the assembly mechanism 20 includes an optical fiber connector clamping tool 201 for positioning and clamping the optical fiber connector 2; an optical cable clamping tool 202 for positioning and clamping the end of the optical cable 1; the optical fiber connector clamping tool 201 and the optical cable clamping tool 202 move relative to each other, so that the ends of the two plastic optical fibers 100a of the optical cable 1 are respectively plugged into the wiring holes of the optical fiber connector 2.

[0086] The assembly mechanism 20 further includes a material pushing tool 203 , through which the optical fiber connectors 2 conveyed by the vibration plate 10 are pushed one by one into the optical fiber connector clamping tool 201 .

[0092] In one embodiment, a lifting cylinder 206 is further provided at the bottom of the optical fiber connector clamping tool 201 to drive the optical fiber connector clamping tool 201 to adjust its height in the vertical direction. The optical fiber connector clamping tool 201 is also provided with a screw mechanism 207 to drive the optical fiber connector clamping tool 201 to adjust its position in the horizontal direction. In conjunction with the height adjustment of the lifting cylinder 206, at this time, only the stamping die in the connector stamping cavity 2011 needs to be replaced so that the assembly jig can assemble optical cable assemblies of different specifications.

[0093] Specifically, Fig.13 As shown, the pushing tooling 203 includes a pushing cylinder 2031 and a pushing rod 2032. The pushing rod 2032 is connected to the piston rod of the pushing cylinder 2031 via a support plate. Under the action of the piston rod of the pushing cylinder 2031, the pushing rod 2032 pushes the optical fiber connector 2 in the transition channel 204 toward the optical fiber connector clamping tooling 201.

[0094] In the present invention, a feeding port is opened on one side of the transition channel 204, which is connected to the conveying line of the vibration disk 10. The optical fiber connectors 2 enter the transition channel 204 one by one from the feeding port along the conveying line, and are pushed toward the optical fiber connector clamping tooling 201 by the pushing rod 2032, thereby realizing continuous loading of the optical fiber connectors 2.

[0095] Furthermore, the pushing tool 203 also includes a pushing slide rail 2033 , and the pushing rod 2032 is connected to a slider on the pushing slide rail 2033 and moves linearly along the pushing slide rail 2033 .

[0096] Specifically, Fig.14 and 15 As shown, the optical cable clamping tool 202 is provided with a clamping member 2021 for clamping the optical cable 1; the optical cable clamping tool 202 is also equipped with a displacement cylinder 2022; the cylinder body of the displacement cylinder 2022 is fixedly connected to the optical fiber connector clamping tool 201, and the piston rod is fixedly connected to the optical cable clamping tool 202; under the action of the displacement cylinder 2022, the optical cable clamping tool 202 is driven to approach the optical fiber connector clamping tool 201, so that the ends of the two plastic optical fibers 100a of the optical cable 1 are sent into the optical fiber connector clamping tool 201.

[0097] For further information, see Fig.16 The clamping member 2021 includes a displacement clamping block 2021a and a floating clamping block 2021b arranged side by side. The displacement clamping block 2021a approaches the floating clamping block 2021b under the action of the clamping cylinder 2021c, thereby clamping the optical cable 1 located therebetween.

[0098] In addition, a floating spring 2021d is provided on a side of the floating clamping block 2021b away from the displacement clamping block 2021a, so that floating clamping is performed between the displacement clamping block 2021a and the floating clamping block 2021b, thereby clamping optical cables 1 of different diameters.

The hydraulic cylinder 302 is mounted above the optical fiber connector clamping tool 201 through the stamping support 301; and under the downward pressure of the piston rod of the hydraulic cylinder 302, the clamping tailstock 200 of the optical fiber connector 2 in the connector stamping cavity 2011 is stamped and fixed; an upper mold is provided at the end of the piston rod of the hydraulic cylinder 302, and a lower mold is provided in the connector stamping cavity 2011, and corresponding convex ridges and grooves are processed in the molding cavities of the upper mold and the lower mold. After the upper mold and the lower mold are closed, the corresponding convex ridges and grooves will cause the clamping tailstock 200 of the stamped optical fiber connector 2 to deform, thereby clamping and fixing the plastic optical fiber 100a inserted in the clamping tailstock 200 to the optical fiber connector 2.

[0100] The present invention also provides a method for using an assembly jig for a tensile-resistant Kevlar dual-core plastic optical cable assembly, comprising the following steps:

[0101] Step A: In the preparation stage, a plurality of optical fiber connectors 2 and a plurality of optical cables 1 are first prepared. The optical fiber connectors 2 are continuously transported by a vibration plate 10, while the optical cables 1 are manually loaded one by one.

[0102] Step B: Start assembly. A plurality of optical fiber connectors 2 are sequentially arranged on the conveyor line under the action of the vibration plate 10 and enter one by one from the feeding port on one side of the transition channel 204;

[0103] Step C: When the induction sensor 205 detects that there is a fiber optic connector 2 in the transition channel 204, the push cylinder 2031 is started, and under its action, the push rod 2032 pushes the fiber optic connector 2 in the transition channel 204 toward the fiber optic connector clamping tool 201, until the clamping tailstock 200 at the rear end of the fiber optic connector 2 is completely placed in the connector stamping cavity 2011, and the front end is located in the transition channel 204 and is axially fixed by the push rod 2032;
