Abstract
Description
Technical Field
[0001] This application relates to the field of cable technology, and more specifically, to an optoelectronic composite cable and a medical device. Background Technology
[0002] Optoelectronic composite cables are a type of composite cable that integrates optical fiber and power conductor. They can transmit optical signals and electrical energy simultaneously, realizing the "electric-optical" dual-channel transmission function. They are widely used in smart grids, communications, and security monitoring.
[0003] Common optoelectronic composite cables consist of optical fibers, electronic wires, and a protective layer. The optical fiber handles high-speed optical signal transmission, where it undergoes photoelectric conversion at the device terminal to achieve high-speed transmission. The electronic wires handle power supply between modules and I²C signal transmission. Typically, the optical fiber is encased in an armored tube, which protects it. However, during mechanical swing tests, the exposed edges of the armored tube can exert shear force on the contacting electronic wires, potentially damaging them.
[0004] In summary, how to effectively solve the problem of poor swing performance in optoelectronic composite cables is a problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this application is to provide an optoelectronic composite cable and a medical device, the structural design of which can effectively solve the problem of poor swing performance of the optoelectronic composite cable.
[0006] To achieve the above objectives, this application provides the following technical solution:

[0008] Armored optical fiber, comprising an armor tube and an optical fiber disposed within the armor tube;
[0009] A woven fiber layer is wrapped around the outside of the armored tube;
[0010] A protective wrapping layer is wrapped around the woven fiber layer;
[0011] Multiple electron wires are distributed circumferentially outside the protective wrapping layer;
[0012] A protective layer surrounds all of the electron wires.
[0013] Optionally, in the above-mentioned optoelectronic composite cable, the braided fiber layer is a braided aramid fiber layer.
[0014] Optionally, in the above-mentioned optoelectronic composite cable, aramid fibers are filled outside the protective wrapping layer, inside the protective layer, and between the plurality of electronic wires.
[0015] Optionally, in the above-mentioned optoelectronic composite cable, the protective wrapping layer includes:
[0016] The first protective wrapping layer is wrapped around the woven fiber layer;
[0017] The second protective wrapping layer is wrapped around the first protective wrapping layer, and the wrapping direction is opposite to that of the first protective wrapping layer.
[0018] Optionally, in the above-mentioned optoelectronic composite cable, the first protective wrapping layer and / or the second protective wrapping layer are polytetrafluoroethylene wrapping layers.
[0019] Optionally, in the above-mentioned optoelectronic composite cable, the protective layer includes a high-temperature resistant shielding layer.

[0021] Optionally, in the above-mentioned optoelectronic composite cable, the protective layer further includes a metal shielding mesh disposed outside the high-temperature resistant shielding layer.
[0022] Optionally, in the above-mentioned optoelectronic composite cable, the protective layer includes an outer sheath disposed on the outermost layer, and the outer sheath includes a sheath body and a plating layer disposed on the body of the sheath.
[0023] Optionally, in the above-mentioned optoelectronic composite cable, the outer diameter of the optoelectronic composite cable is no greater than 8mm, and the number of optical fibers is no less than 4.
[0024] The optoelectronic composite cable provided in this application includes at least armored optical fiber, a braided fiber layer, a protective wrapping layer, electronic wires, and a protective layer. The armored optical fiber includes an armor tube and optical fibers disposed within the armor tube; the braided fiber layer is wrapped around the armor tube; the protective wrapping layer is wound around the braided fiber layer; multiple electronic wires are provided and distributed circumferentially outside the protective wrapping layer; and the protective layer wraps around all electronic wires.
[0025] The optoelectronic composite cable provided in this application employs an armored tube to ensure unobstructed fiber threading and improves the bending resistance of the subsequently threaded optical fiber. Furthermore, a tightly braided fiber layer is added to the outside of the armored tube, and a protective wrapping tape layer is placed outside the braided fiber layer. The two layers work together to secure the armored tube, allowing it to combine the characteristics of both the braided fiber layer and the protective wrapping tape layer. Simultaneously, the braided fiber layer and the protective wrapping tape layer isolate and protect the external electronic wires, preventing damage from the sharp edges of the armored tube.

This ensures the medical device maintains good working condition and provides high-quality medical data. Furthermore, the longer lifespan of the optoelectronic composite cable extends the lifespan of the medical device, reducing maintenance costs and thus lowering overall medical costs.

[0033] This application discloses an optoelectronic composite cable and a medical device that improves the cable's swing performance.
[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0035] The number of optical fibers in the optoelectronic composite cable provided in this application can be set as needed and is not specifically limited. For example, the number of optical fibers is not less than four. If four optical fibers are used, a large-diameter armored tube needs to be reserved for threading the fibers. The outer diameter of the optoelectronic composite cable is set according to different requirements; for example, the outer diameter of the optoelectronic composite cable is not greater than 8mm. Therefore, within a limited space, the armored tube cannot be sheathed. During mechanical swing testing, the exposed edge of the armored tube will exert shear force on the contacting electronic wires, damaging them. Furthermore, the armored tube is elastic; after cutting, the armored tube shrinks back, and the head of the armored tube is not the same length as the electronic wire, which will also affect the use of the optoelectronic composite cable. In this application, a braided fiber layer and a wrapping layer are added to the outside of the armored tube to improve the defects of the armored tube and to isolate and protect the outer electronic wires.
[0036] In some embodiments, please refer to Figures 1-2 The optoelectronic composite cable provided in this application includes armored optical fiber 1, braided fiber layer 2, protective wrapping layer 3, electronic wires 4, and a protective layer. The armored optical fiber 1 includes an armor tube 11 and optical fibers disposed within the armor tube 11. The armor tube 11 serves to protect the optical fibers and enhance their mechanical strength. For example, the armor tube 11 is made of plastic. When multiple optical fibers are provided, all fibers can be disposed within the armor tube 11. The braided fiber layer 2 wraps around the armor tube 11, and the protective wrapping layer 3 is wound around the braided fiber layer 2. That is, the armor tube 11 is sequentially surrounded by the braided fiber layer 2 and the protective wrapping layer 3. Multiple electronic wires 4 are provided and distributed circumferentially outside the protective wrapping layer 3; the protective layer is disposed around all electronic wires 4. In other words, multiple electronic wires 4 are surrounded by the protective wrapping layer 3, and a protective layer is provided on the entire outer surface to protect the electronic wires 4 and the armored optical fiber 1.
[0037] The optoelectronic composite cable provided in this application employs an armored tube 11 to ensure unobstructed fiber threading and improve the bending resistance of the subsequently threaded optical fiber. Furthermore, a tightly braided fiber layer 2 is added to the outside of the armored tube 11, and a protective wrapping layer 3 is placed outside the braided fiber layer 2. The armored tube 11 is fixed in place by the combined effect of these two layers, allowing it to utilize the characteristics of both the braided fiber layer 2 and the protective wrapping layer 3. Simultaneously, it isolates and protects the external electronic wires 4, preventing damage from the sharp edges of the armored tube 11, controlling the extensibility of the armor, and minimizing wire stretching and deformation, thereby improving the overall sway performance of the optoelectronic composite cable.
[0038] In some embodiments, the braided fiber layer 2 is a braided aramid fiber layer, for example, a braided Kevlar fiber layer. Aramid fiber (poly(p-phenylene terephthalamide)) has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight, and also has excellent toughness. Therefore, wrapping it around the armor tube 11 can improve the tensile strength and ductility of the armor tube 11, while reliably separating the armor tube 11 from the electron wire 4.
[0039] In some embodiments, aramid fibers 5 are filled outside the protective wrapping layer 3, inside the protective layer, and between the multiple electronic wires 4. For example, the aramid fiber 5 is Vikeval fiber. By filling the optoelectronic composite cable with aramid fibers 5, the ultra-high strength, high modulus, and excellent toughness of aramid fibers 5 can be combined, greatly enhancing the tensile strength and ductility of the optoelectronic composite cable. For example, the electronic wires 4 are dispersed outside the protective wrapping layer 3, and are prone to loosening and deformation. By filling the inside with aramid fibers 5, the tensile strength of the optoelectronic composite cable is enhanced, while the electronic wires 4 are made more tightly packed around their perimeter, thus preventing loosening and deformation.
[0040] In some embodiments, the protective strap layer 3 includes a first protective strap layer 31 and a second protective strap layer 32. The first protective strap layer 31 is wound around the woven fiber layer 2; the second protective strap layer 32 is wound around the first protective strap layer 31, and the winding direction is opposite to the winding direction of the first protective strap layer 31. It is understood that the winding directions of the first protective strap layer 31 and the second protective strap layer 32 are opposite; that is, if the winding direction of the first protective strap layer 31 is considered positive, the winding direction of the second protective strap layer 32 is negative. In one example, on a cross-section perpendicular to the axial direction, if the winding direction of the first protective strap layer 31 from the inside to the outside is clockwise, then the winding direction of the second protective strap layer from the inside to the outside is counterclockwise. In another example, the winding directions of the first protective strap layer 31 and the second protective strap layer 32 are interchanged. With the above settings, the first protective wrapping layer 31 and the second protective wrapping layer 32 are wound in opposite directions, which makes the force on the optoelectronic composite cable more uniform in different directions, the performance consistency better, and the wrapping tighter.
[0041] In some embodiments, the first protective wrapping layer 31 is a polytetrafluoroethylene (PTFE) wrapping layer. That is, the first protective wrapping layer 31 is made of polytetrafluoroethylene (PTFE). PTFE wrapping has low density, low dielectric loss, stable dielectric constant, and excellent temperature resistance, making it an excellent insulating material for optoelectronic composite cables. It also provides good sealing. Furthermore, due to the high tensile strength of PTFE wrapping, the ductility of the armor can be controlled, preventing the cut wires from easily stretching or deforming.
[0042] In some embodiments, the second protective wrapping layer 32 is a polytetrafluoroethylene (PTFE) wrapping layer. That is, the material of the second protective wrapping layer 32 is PTFE, and its effect can be referred to the above embodiments, which will not be repeated here.
[0043] In some embodiments, the protective layer includes a high-temperature resistant shielding layer 6. To improve EMC (Electromagnetic Compatibility) performance, optoelectronic composite cables often use braided wrapping of the electron wires 4 to shield against electromagnetic interference and reduce interference from external electromagnetic waves to internal signals. However, the shielding rate of braiding is often less than 100%, requiring the use of aluminum foil Mylar in conjunction with the braiding. However, since aluminum foil Mylar has a short-term temperature resistance of 180°C and a long-term temperature resistance of 120°C, it limits the processing of optoelectronic composite cables. In this embodiment, a high-temperature resistant shielding layer 6 is used instead of aluminum foil Mylar, utilizing the high-temperature resistance of the high-temperature shielding layer 6 to meet the high-temperature processing requirements of optoelectronic composite cables. For example, high-temperature resistance refers to a material that can withstand 200°C.
[0044] In some embodiments, the high-temperature shielding layer 6 includes a graphene wrapping layer wound around the entire electronic wire 4. That is, the entire outer surface of the armor tube 11, which has a braided fiber layer 2 and a protective wrapping layer 3, and the electronic wire 4 disposed outside the armor tube 11, is wrapped with graphene wrapping. On the one hand, due to the high-temperature resistance of the graphene wrapping, it can maintain stable performance and tensile strength in high-temperature environments. On the other hand, the graphene wrapping has excellent shielding performance, thus effectively preventing the signal of the optoelectronic composite cable from being interfered with by external electromagnetic waves.
[0045] In some embodiments, the protective layer further includes a metal shielding mesh 7 disposed outside the high-temperature resistant shielding layer 6. For example, a metal shielding mesh 7 is also disposed outside the graphene wrapping layer. The combined shielding effect of the metal shielding mesh 7 and the graphene wrapping layer significantly improves the EMC performance of the optoelectronic composite cable.
[0046] In some embodiments, the protective layer further includes an outer sheath 8 disposed on the outermost layer. The outer sheath 8 includes a sheath body and a plating layer disposed on the outer surface of the sheath body. The outer sheath 8 provides protection. In this embodiment, the outer sheath 8 is an outer coated sheath, that is, a plating layer is disposed on the outer surface of the sheath body. The plating layer can be configured according to the protection requirements. For example, the plating layer is a waterproof plating layer, a stain-resistant plating layer, or a wear-resistant plating layer, etc., or the plating layer can be selected from materials that integrate the aforementioned protective functions to improve the cable's waterproof, stain-resistant, and scratch-resistant performance. For example, the sheath body is a silicone sheath to increase the cable's flexibility. Since the processing temperature of the silicone coating is generally around 200°C, to meet the above processing requirements, the second protective wrapping layer 32 and the electronic wire 4 are integrally provided with the aforementioned high-temperature resistant shielding layer 6.
[0047] In some embodiments, the armored optical fiber 1 is located at the center of the optoelectronic composite cable, and multiple electronic wires 4 are provided, with the multiple electronic wires 4 surrounding the second protective wrapping layer 32. Placing the armor tube 11 at the center of the optoelectronic composite cable reduces the stress and bending of the optical fiber, ensuring unobstructed fiber insertion. The distribution of the electronic wires 4 around the armor tube 11 makes the overall cable structure more evenly stressed.
[0048] In some embodiments, at least some of the electronic wires 4 have different outer diameters, and the electronic wires 4 with different outer diameters are distributed circumferentially along the second protective wrapping layer 32, with aramid fibers 5 filling the area around the smaller outer diameter electronic wires 4. It is understood that the smaller outer diameter electronic wires 4 here refer to the relatively smaller outer diameter electronic wires 4 in the optoelectronic composite cable. When the outer diameters of the electronic wires 4 are different, the smaller outer diameter electronic wires 4 are prone to loosening and deformation. Therefore, by filling the area around the smaller outer diameter electronic wires 4 with aramid fibers 5, the area around the electronic wires 4 can be made more compact and less prone to loosening and deformation. At the same time, it can also enhance the tensile strength of the optoelectronic composite cable. Furthermore, the smaller the outer diameter of the electronic wire 4, the more aramid fibers 5 are filled around it. Since the smaller the outer diameter of the electronic wire 4, the larger the gaps around it, the more aramid fibers 5 are filled to make the area around the electronic wire 4 more compact.
[0049] For example, electronic wires 4 with different outer diameters are symmetrically distributed across a cross section of the optoelectronic composite cable to make the overall structure of the cable more evenly stressed.
[0050] In some embodiments, the electronic wire 4 includes a coaxial cable 41 for transmitting I²C signals. Using the coaxial cable 41 for the I²C signals not only meets signal requirements but also improves the wire's sway performance. For example, to prevent interference from external electromagnetic waves on the I²C signals, a high-temperature resistant shielding layer 6 as described in the above embodiments can be provided.
[0051] In some embodiments, the outer diameter of the optoelectronic composite cable is no greater than 8mm, and the number of optical fibers is no less than 4. Through the design of the structure and materials of each layer of the optoelectronic composite cable in this application, it is possible to achieve a smaller outer diameter of the optoelectronic composite cable while maximizing optical fiber communication. That is, the outer diameter of the optoelectronic composite cable is no greater than 8mm, while the number of optical fibers can be no less than 4. Therefore, the optoelectronic composite cable is more flexible and lightweight in use.
[0052] Based on the medical devices provided in the above embodiments, this utility model also provides a medical device, which includes a handheld end and a main unit end, and the handheld end and the main unit end are connected by any one of the optoelectronic composite cables in the above embodiments. Since this medical device uses the optoelectronic composite cable in the above embodiments, the beneficial effects of this medical device can be referred to the above embodiments.
[0053] For medical devices with handheld terminals, the frequent movement of the handheld terminal causes the cable to move, such as bending or twisting. The optoelectronic composite cable of this application can effectively cope with the above scenarios, improve the stability of medical devices, and extend their service life.
