Description

Technical Field

[0001] The embodiments of this utility model relate to the field of cables. More specifically, this utility model relates to a photoelectric hybrid spring cable. Background Technology

[0002] With the advancement of technology and the deepening of its applications, laser medical or laser processing applications, which involve significant variations in length and flexible placement, place higher demands on the flexibility and adaptability of hybrid optoelectronic cables. In these applications, hybrid optoelectronic cables need to be of sufficient length to connect lightweight, movable parts of the instrument (such as laser therapy handheld devices) to bulky, fixed parts (such as the laser therapy main unit). This ensures that the movable parts can move freely relative to the fixed parts under the control of the user or the machine, achieving the intended function (such as treatment).

[0003] Then, the existing optoelectronic hybrid cables are mainly composed of stranded wire groups and outer sheaths covering the stranded wire groups. They have almost no excellent elasticity and self-organizing characteristics, which means that they have to be too long in order to be suitable for the aforementioned scenarios. This not only takes up a lot of space, but is also prone to confusion and knots during use, increasing the risk of instrument use. Utility Model Content

[0004] To address one or more of the technical problems mentioned above, this utility model provides a photoelectric hybrid spring cable, which has excellent elasticity and self-organizing properties. It occupies little space during use, is not easily tangled or messy, and effectively reduces the risk of instrument use.

[0005] This utility model provides a photoelectric hybrid spring cable, which includes a cable body with a spiral structure. The cable body includes an outer sheath and a stranded wire group disposed inside and wrapped by the outer sheath. The stranded wire group includes an optical fiber sub-wire and a conductive sub-wire, wherein the spiral direction of the spiral structure is opposite to the stranding direction of the stranded wire group.

[0006] Furthermore, the radius of the spiral structure is greater than or equal to the minimum bending radius of the optical fiber sub-line, and less than or equal to four times the radius of the cable body.

[0007] Furthermore, the number of optical fiber sub-wires is one or more, the number of conductive sub-wires is multiple, the stranded wire group also includes a tensile core, the optical fiber sub-wire includes an optical fiber and an outer sheath wrapped around the optical fiber, one optical fiber sub-wire and multiple conductive sub-wires are wound together on the tensile core along a predetermined stranding direction; the tensile core is made of aramid with a fineness greater than or equal to 250 denier.

[0008] Furthermore, the number of optical fiber sub-wires is one, and the number of conductive sub-wires is multiple. The optical fiber sub-wire includes an optical fiber and an outer sheath wrapped around the optical fiber. Multiple conductive sub-wires are wound together on the optical fiber sub-wire along a predetermined stranding direction.

[0009] Furthermore, the number of optical fiber sub-wires is one, the diameter of the cable body is greater than 2.0 mm but not more than 3.0 mm, the number of conductive sub-wires is multiple, the optical fiber sub-wire includes an optical fiber, and multiple conductive sub-wires are wound together on the optical fiber along a predetermined stranding direction.

[0010] Furthermore, the number of optical fiber sub-wires is one or more, the number of conductive sub-wires is multiple, and all the optical fiber sub-wires and all the conductive sub-wires are twisted together along a predetermined twisting direction.

[0011] Furthermore, the stranded wire assembly also includes reinforcing wires stranded together with the optical fiber sub-wires and conductive sub-wires. The elongation of the reinforcing wires is lower than that of the optical fiber sub-wires and the conductive sub-wires. The reinforcing wires are symmetrically distributed in the stranded wire assembly. The reinforcing wires are made of aramid with a fineness greater than or equal to 250 denier. The reinforcing wires have the same length as the conductive sub-wires.

[0012] Furthermore, the multiple conductive sub-wires have the same diameter, and the cross-section of the stranded wire assembly is circular.

[0013] Furthermore, the fiber optic sub-line has a fiber screening strength of 200 kpsi, and the fiber optic sub-line is selected such that its fiber attenuation strength is less than or equal to 0.1 dB when its bending diameter is less than or equal to 3 times the diameter of the cable body.

[0014] Furthermore, the conductive sub-wire includes at least one copper wire and an insulating layer covering all the copper wires; the number of copper wires wrapped by the insulating layer is multiple, and the multiple copper wires are twisted together to form a copper wire group, the twisting direction of the copper wire group being opposite to the helical direction of the helical structure.

[0015] The optoelectronic hybrid spring cable provided above employs a stranded wire assembly with fiber optic and conductive sub-wires, and the cable body features a helical structure. This allows it to not only simultaneously transmit data and supply power at high and low speeds, but also provides excellent flexibility and self-organizing properties. This ensures that the optoelectronic hybrid spring cable maintains a small footprint, is less prone to tangling and mess, and effectively reduces the risks associated with instrument use. Furthermore, because the helical direction of the helical structure is opposite to the twisting direction of the stranded wire assembly, its service life is significantly improved.

[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0025] Figure 1 This is a perspective view of the photoelectric hybrid spring cable according to an embodiment of the present utility model; Figure 2 for Figure 1 A partial cross-sectional view of the photoelectric hybrid spring cable shown. Figure 1 and Figure 2As shown, an embodiment of this utility model provides a photoelectric hybrid spring cable. This photoelectric hybrid spring cable includes a cable body 1 having a helical structure 1a. In terms of shape, in addition to the helical structure 1a, the cable body 1 also includes a first connecting segment 1b and a second connecting segment 1c respectively connected to both ends of the helical structure 1a, wherein the first connecting segment 1b and the second connecting segment 1c can be arranged opposite to each other (see [reference]). Figure 1 It can also be set to face each other, or other configurations. In terms of composition, the cable body 1 includes an outer sheath 11 and a stranded wire assembly 12 disposed within and enclosed by the outer sheath 11. For example... Figure 2 and Figure 3 As shown, the stranded wire assembly 12 includes at least one optical fiber sub-wire 121 and at least one conductive sub-wire 122. Each optical fiber sub-wire 121 is used to transmit optical signals to achieve high-speed data transmission. The conductive sub-wire 122 is used to transmit electrical energy for power supply, or to transmit electrical signals for low-speed data transmission. When there are multiple conductive sub-wires 122, all of them can transmit electrical energy or electrical signals, or some conductive sub-wires 122 can be used to transmit electrical signals while others transmit electrical energy.

[0026] The optoelectronic hybrid spring cable adopts a stranded wire group 12 with optical fiber sub-wires 121 and conductive sub-wires 122, and the main body of the cable 1 has a spiral structure 1a. This ensures that the optoelectronic hybrid spring cable not only has comprehensive functions such as high and low speed simultaneous data transmission and power supply, but also has excellent elasticity and self-organizing characteristics (i.e., the automatic contraction of the spiral structure 1a). This allows the optoelectronic hybrid spring cable to have advantages such as small footprint, easy knotting and easy tangling when used, and effectively reduces the risk of instrument use.

[0027] In this embodiment, the cross-section of the stranded wire assembly 12 is preferably circular. When the cross-section of the stranded wire assembly 12 is approximately circular, the diameters of the optical fiber sub-wires 121 and the conductive sub-wires 122 within the stranded wire assembly 12 are the same or approximately the same, which is beneficial for improving the elasticity and self-aligning characteristics of the optoelectronic hybrid spring cable. Furthermore, this also helps to ensure uniform stress distribution throughout the optoelectronic hybrid spring cable during use, thereby extending its service life.

[0028] In this embodiment, the radius of the spiral structure 1a is greater than or equal to the minimum bending radius of the optical fiber sub-line 121. This effectively avoids signal attenuation or breakage of the optical fiber 1211 due to excessive deformation during bending. Meanwhile, the radius of the spiral structure 1a (i.e., half the outer diameter of the spiral structure 1a) is preferably less than or equal to four times the radius of the cable body 1 (i.e., the cross-sectional radius) to effectively avoid the risk of severe uncontrolled deformation such as collapse of the spiral structure 1a when stretched and / or suspended.

[0029] As an example, the outer sheath 11 includes at least one layer structure, and the at least one layer structure preferably includes a thermoplastic polyurethane elastomer rubber layer. The thermoplastic polyurethane elastomer rubber layer is made of thermoplastic polyurethane elastomer rubber (TPU). TPU has the characteristics of rapid recovery in a short time, high mechanical strength, and good wear resistance. The outer sheath 11 can provide good protection for the stranded wire assembly 12 and provide a certain degree of reinforcement for the elastic deformation of the spiral structure 1a. Since the spiral structure 1a is heat-formed, the deformation temperature of TPU is higher than the baking temperature. Using TPU as the outer sheath 11 can ensure the integrity of the cable body 1, especially the spiral structure 1a, during the molding process.

[0030] As an example, the fiber optic sub-line 121 includes at least an optical fiber 1211 for transmitting optical signals, and may also include an outer sheath 1212 wrapped around the optical fiber 1211. The outer sheath 1212 is made of fluoroplastic, which has a high melting point and good mechanical properties, ensuring structural integrity during the formation of the helical structure 1a and providing reliable protection for the optical fiber 1211. Preferably, the optical fiber 1211 is a high-strength optical fiber with a screening strength of 200 kpsi. This high-strength optical fiber can better withstand the mechanical stress of the optoelectronic hybrid spring cable during frequent bending, stretching, and other dynamic use, effectively avoiding the risk of fiber optic breakage or performance degradation, and also ensuring long-term stability and high quality of data transmission. More preferably, the fiber optic sub-line 121 is selected such that when its bending diameter is less than or equal to 3 times the diameter of the cable body 1, the attenuation strength of its optical fiber 1211 is less than or equal to 0.1 dB. Since the bending radius of the fiber optic sub-line 121 is less than or equal to 3 times the diameter of the cable body 1 during use, it can be ensured that the fiber optic sub-line 121 can transmit optical signals efficiently and at high speed.

[0031] As an example, the conductive sub-wire 122 includes at least one copper wire 1221 and an insulating layer 1222 covering all the copper wires 1221. The insulating layer 1222 is made of fluoroplastic, which is an outer sheath material with a high melting point and good mechanical properties. This ensures that the material remains unchanged during the formation of the helical structure 1a, provides reliable protection for the at least one copper wire 1221, and improves the mechanical properties of the at least one copper wire 1221. Preferably, the number of copper wires 1221 wrapped by the insulating layer 1222 is multiple, and these multiple copper wires 1221 are formed into a copper wire group by twisting. The copper wire group can improve the conductivity and anti-interference ability of the conductive sub-wire 122, as well as its toughness, elasticity, and durability. Experiments mentioned below verify that in this optoelectronic hybrid spring cable, if the twisting direction of the copper wire group is opposite to the helical direction of the helical structure 1a, the elasticity, self-adjusting characteristics, and service life of the optoelectronic hybrid spring cable can be further enhanced. It is understandable that when the optoelectronic hybrid spring cable is repeatedly stretched, the twisting direction of the copper wire group is opposite to the rotation direction of the spiral structure 1a. Therefore, the torque of the spring wire is opposite to the torque direction of the copper wire group, which reduces the deformation of the copper wire group during use, thereby improving the quality and service life of the final cable.

[0032] Preferably, the copper wire 1221 can be selected from bare copper, tin-plated soft round copper wire, or silver-plated soft round copper wire. Tin-plated soft round copper wire has advantages such as strong signal transmission stability and low price. Silver-plated soft round copper wire has good thermal conductivity, electrical conductivity, and solderability, good ductility, and the silver layer has high corrosion resistance. Among bare copper, tin-plated soft round copper wire, and silver-plated soft round copper wire, although silver-plated soft round copper wire is more expensive, it has good oxidation resistance, is easy to solder, and has the best electrical conductivity. Under the same performance requirements, silver-plated soft round copper wire has the smallest diameter, which can reduce the diameter of the cable. Therefore, silver-plated soft round copper wire is the best choice for the copper wire 1221.

[0033] Next, combine Figures 3 to 6 The specific structure of the optoelectronic hybrid spring cable is described in detail. For example... Figure 3As shown, the stranded cable assembly 12 includes one or more optical fiber sub-wires 121 and multiple conductive sub-wires 122, as well as a tensile core 124. The tensile core 124 can be made of tensile-resistant materials such as aramid with a fineness greater than or equal to 250 denier to reduce the risk of the optoelectronic hybrid spring cable being torn or broken during use. During the stranding process, all optical fiber sub-wires 121 and all conductive sub-wires 122 can be wound together on the tensile core 124 along a predetermined stranding direction, thereby obtaining an optoelectronic hybrid spring cable with superior overall performance. That is, the optoelectronic hybrid spring cable not only has better extensibility and self-organizing characteristics, but its tensile strength can also be significantly increased. As a preferred example, the optical fiber sub-wire 121 includes an optical fiber 1211 and an outer sheath 1212 wrapped around the optical fiber 1211. The outer sheath 1212 can be made of fluoroplastic, which has a high melting point and good mechanical properties, ensuring structural integrity during the formation of the helical structure 1a and providing safe and reliable protection for the optical fiber 1211.

[0034] like Figure 4 As shown, the stranded wire assembly 12 includes an optical fiber sub-wire 121 and multiple conductive sub-wires 122. The optical fiber sub-wire 121 includes an optical fiber 1211 and an outer sheath 1212 wrapped around the optical fiber 1211. The multiple conductive sub-wires 122 are wound together on the optical fiber sub-wire 121 along a predetermined stranding direction (i.e., the optical fiber sub-wire 121 does not participate in the stranding), thereby obtaining a hybrid optoelectronic spring cable with better overall performance but a thinner wire diameter (e.g., more than 3.0 mm but not more than 6.5 mm). That is, the hybrid optoelectronic spring cable not only has excellent elasticity, better self-organizing characteristics and longer service life, but its wire diameter can also be made thinner.

[0035] like Figure 5 As shown, the stranded wire assembly 12 includes one or more optical fiber sub-wires 121 and multiple conductive sub-wires 122. The optical fiber sub-wire 121 includes an outer sheath 1212 wrapped around an optical fiber 1211. All optical fiber sub-wires 121 and all conductive sub-wires 122 are stranded together along a predetermined stranding direction. That is, the sub-wire at the center position alternates between being an optical fiber sub-wire 121 and a conductive sub-wire 122 along the overall extension direction of the stranded wire assembly 12. This results in a hybrid optoelectronic spring cable with superior overall performance but a thinner wire diameter (e.g., exceeding 3.0 mm but not exceeding 6.5 mm). This hybrid optoelectronic spring cable not only has excellent elasticity, better self-organizing characteristics, and a longer service life, but its wire diameter can also be made thinner.

[0036] like Figure 6As shown, the stranded wire assembly 12 includes an optical fiber sub-wire 121 and multiple conductive sub-wires 122. The optical fiber sub-wire 121 consists only of optical fiber 1211, and the multiple conductive sub-wires 122 are wound together on the optical fiber 1211 (the optical fiber sub-wire 121 does not participate in the stranding) along a predetermined stranding direction. This results in a hybrid optoelectronic spring cable with superior overall performance and the thinnest wire diameter (especially exceeding 2.0 mm but not exceeding 3.0 mm). That is, this hybrid optoelectronic spring cable not only has excellent elasticity and better self-organizing characteristics, but its wire diameter can also be minimized. It is understood that the optical fiber 1211 includes a core, a cladding, and a coating layer. The core and cladding are made of high-melting-point silica, and the coating layer is composed of a polymer with a melting point of 200°C to 300°C. The baking and shaping temperature of the spiral structure 1a is lower than the melting point of the optical fiber 1211. The forming conditions of the hybrid optoelectronic spring cable can also be met by using a stranded wire assembly consisting only of the optical fiber sub-wire 1211 and multiple conductive sub-wires 122.

[0037] In this embodiment, as Figures 3 to 6 As shown, the stranded wire assembly 12 may further include a reinforcing wire 123 stranded together with the optical fiber sub-wire 121 and the conductive sub-wire 122. This reinforcing wire 123 may be made of aramid fiber with a fineness greater than or equal to 250 denier. However, since the elongation of the reinforcing wire 123 is lower than that of the optical fiber sub-wire 121 and the conductive sub-wire 122, the reinforcing wire 123 can effectively enhance the overall strength and tensile strength of the optoelectronic hybrid spring cable, especially the stranded wire assembly 12. This allows the optoelectronic hybrid spring cable to better maintain the stability and integrity of its structure when subjected to external forces, while avoiding performance degradation or damage to the optical fiber sub-wire 121 and the conductive sub-wire 122 due to excessive stretching.

[0038] In this embodiment, the number of reinforcing wires 123 can be one or more, and when there are multiple reinforcing wires 123, they are symmetrically distributed in the stranded wire group 12 to improve the overall performance of the optoelectronic hybrid spring cable, especially the overall strength and tensile strength of the stranded wire group 12. Preferably, the length of the reinforcing wires 123 is approximately the same as that of the conductive wires 122, so that the reinforcing wires 123 can bear more of the tensile force when the optoelectronic hybrid spring cable is stretched.

[0039] In this embodiment, the optoelectronic hybrid spring cable may further include connectors (not shown) with optoelectronic conversion modules located at both ends of the cable body 1, wherein the connectors can be plugs or sockets. This improves the ease of use of the optoelectronic hybrid spring cable and even simplifies installation and maintenance.

[0040] Experimental instructions

[0041] Optoelectronic hybrid spring cables (hereinafter referred to as spring cables) with a cross-sectional outer diameter of 2.9 mm, prepared by different methods, were selected. Each type of spring cable was divided into three groups, and each group of spring cables underwent tensile, bending, and pull-back tests, and the average value of the test results was obtained. In the specific preparation method, the structure of each spring cable was the same, and five samples were obtained by controlling the direction of the copper wire group, the stranded wire group, and the spiral of the spring cable.

[0042] The tensile test involves clamping both ends of the spring cable (i.e., the ends of the first connecting segment 1b and the second connecting segment 1c) with a tensile testing machine, applying 120N at a speed of 2N / s and maintaining it for 1 minute, and obtaining and calculating the resistance change rate and light transmission efficiency of the spring cable.

[0043] The bending test involves clamping one end of the spring cable with a bending tester and hanging a 5N weight on the other end of the spring cable to keep it in a stretched state. This allows the bending tester to bend the spiral structure 1a of the spring cable by ±90 degrees for 6000 times. The resistance change rate and light transmission efficiency of the spring cable are then obtained and calculated.

[0044] Tensile testing involves clamping both ends of the spring cable using a tensile device and stretching the spring cable to 85-90% of its length before the formation of the unformed spiral structure 1a. This process is repeated 16,000 times to obtain and calculate the rate of change of resistance and the light transmission efficiency of the spring cable.

[0045] Table: Performance Results of Optoelectronic Hybrid Spring Cable in Experiments

[0046]

[0047]

[0048] The above experiments verify that in this optoelectronic hybrid spring cable, if the helical direction of the spiral structure 1a is set opposite to the stranding direction of the stranded wire group 12, the optoelectronic hybrid spring cable exhibits significantly superior conductivity and light transmission characteristics, with better elasticity, self-adjusting properties, and a longer service life. Furthermore, if the stranding direction of the copper wire group is opposite to the helical direction of the spiral structure 1a, the elasticity, self-adjusting properties, and service life of the optoelectronic hybrid spring cable can be further enhanced. It should be noted that during the tensile test of the optoelectronic hybrid spring cable, due to the repeated stress on the internal copper wires, the structure changes. Generally, the copper wires become thinner, causing an increase in resistivity, thus affecting the transmission of electrical signals. Samples with 0% light transmission are considered defective because the optical fiber has already been damaged during the test, and further resistance testing is unnecessary.
