Description

Technical Field

[0001] The utility model relates to the technical field of USB interface type optical fiber jumpers, in particular to a USB interface type optical fiber jumper with a length-adjustable structure. Background Art

[0002] With the development of information technology and network technology, optical fiber is used more and more widely as a medium for signal transmission. USB interface fiber optic patch cables are used to transmit high-speed data between devices with USB interfaces, while utilizing the characteristics of optical fiber to provide higher bandwidth, lower latency and stronger anti-interference capabilities.

[0003] According to the search, Chinese patent document, publication number: CN214954267U, discloses a fiber optic patch cord, which includes: an optical cable, two connectors, a plastic optical fiber and two label blocks; the two connectors are located at both ends of the optical cable, and are used to detachably connect the optical cable to other optical cables; the end faces of the two plastic optical fibers are cut flat and fixedly connected to the outer surface of the optical cable, the end faces of the plastic optical fibers are used to receive and output detection light, and the plastic optical fibers are used to transmit detection light; the label block is fixedly installed on the outer surface of the optical cable through a snap-fit ​​structure, and the label block has a through hole for fixing the two ends of the plastic optical fiber in the through hole, which serves as the input and output ports of the traceable detection light. It can quickly determine the position of the two ports connected by the jumper, reduce costs, simplify assembly, and effectively avoid electromagnetic interference. However, the fiber optic jumper of this mechanism cannot be adjusted in length. If the jumper is too long, the excess part needs to be bundled or hidden, otherwise it will cause a waste of space and easily create a messy wiring environment. Excessively long cables may also become a safety hazard, such as a tripping risk or increased maintenance difficulty. During the installation process, if the jumper length is not appropriate, it may be necessary to reselect a jumper of the appropriate length, which increases installation time and cost.

[0004] Therefore, for the above-mentioned fiber optic patch cord, which cannot be adjusted in length and easily creates a messy wiring environment, and an overly long cable may also become a safety hazard, a USB interface fiber optic patch cord with an adjustable length structure can be designed. When the user rotates knob two, it drives the rotation of winding roller two, driving wire body three to be rolled up or released, thereby adjusting the length of the entire patch cord. The excess cable can be rolled up to avoid messy wiring, thereby solving the above-mentioned problem. Utility Model Content

[0023] See also Figures 1-4In this embodiment, the inner bottom surface of the regulating box 3 is connected to a driven gear 9 through a bearing, and the upper end surface of the driven gear 9 is fixedly provided with a winding roller 10, and the end of the line body 2 close to the fixed block 4 is wound around the surface of the winding roller 10. When the driven gear 9 rotates, it drives the winding roller 10 to rotate, so that the line body 2 can be wound or released, and a connecting rod 12 is rotatably connected in the upper end surface groove of the regulating box 3. The upper end surface of the connecting rod 12 is fixedly provided with a knob 13, and the lower end surface of the connecting rod 12 is fixedly provided with a driving gear 11. The driving gear 11 is meshed with the driven gear 9. When the user rotates the knob 13, the knob drives the connecting rod 12 to rotate, and the rotation of the connecting rod 12 drives the driving gear 11 to rotate. The driven gear 11 rotates the driven gear 9 by meshing with the driven gear 9, thereby driving the winding roller 10 to rotate. The rotation of the winding roller 10 will cause the wire body 2 to be wound up or released, thereby adjusting the length of the wire body 2, so that the length of the fiber optic interface 1 jumper can be adjusted. The end of the wire body 3 7 away from the fixed block 4 is fixedly connected to the installation box 8, and the interior of the installation box 8 is installed with a photoelectric signal conversion processing chip 19. The photoelectric signal conversion processing chip 19 is installed in the installation box 8 at the end of the wire body 3 7. When the optical signal reaches the installation box 8 through the optical fiber, the photoelectric signal conversion processing chip 19 converts it into an electrical signal. Conversely, when the electrical signal is transmitted from the USB interface, the photoelectric signal conversion processing chip 19 converts it into an optical signal and transmits it through the optical fiber.

[0024] See also Figures 1-4In this embodiment, the line body three 7 is an optical signal line. The line body three 7 passes through the installation box 8 and is connected to the optoelectronic signal conversion processing chip 19 circuit. The optoelectronic signal conversion processing chip 19 converts the electrical signal input from the USB interface into an optical signal and transmits it through the line body three 7. The circuit of the optoelectronic signal conversion processing chip 19 on the side away from the line body three 7 is fixedly connected to one end of the electrical signal line 21. The other end of the electrical signal line 21 is connected to the USB interface body 22 through the line body.

The output end of the optical fiber interface 1 is fixedly connected to the optical fiber panel The surfaces of the socket 20, knob 1 13 and knob 2 18 are all covered with rubber pads. The photoelectric signal conversion processing chip 19 draws power from the terminal device through the USB interface body 22, and transmits the converted electrical signal to the terminal device through the USB interface body 22, and transmits the converted optical signal to the network device through the optical fiber interface 1. The rubber pad can increase the friction of the knob, so that the user feels better when rotating the knob and the operation is more comfortable. The optical fiber interface 1 is used to connect the optical fiber panel socket 20 to realize the connection between the optical fiber jumper and the optical fiber network device or optical fiber panel. The optical fiber panel socket 20 is used to be inserted into the interface of the corresponding optical fiber panel or terminal device to realize the transmission of optical fiber signals.

[0025] During operation, when the user rotates the knob 2 18, the knob drives the connecting rod 2 17 to rotate, and then drives the driving gear 2 16 to rotate. The driving gear 2 16 meshes with the driven gear 2 14 to rotate the driven gear 2 14, thereby driving the two winding rollers 2 15 to rotate. The rotation of the winding roller 2 15 drives the wire body 3 7 to be wound up or released, thereby adjusting the length of the entire jumper. The user can adjust the jumper length as needed to suit different scenarios. When long-distance connection is not required, the excess cables can be retracted to avoid messy wiring. For applications where the wiring environment changes frequently, this structure can greatly improve The convenience and efficiency of wiring are improved. At the same time, one rotation of the driving gear 2 16 can drive the driven gear 2 14 to rotate four times, so that the user can quickly adjust the length of the jumper wire. The driving gear 2 16 and the driven gear 2 14 can be set in different proportions according to needs. When the driven gear 19 rotates, it will drive the winding roller 10 to rotate, so that the wire body 2 can be wound or released. When the user rotates the knob 13, the knob drives the connecting rod 12 to rotate, and the rotation of the connecting rod 12 drives the driving gear 11 to rotate. The driving gear 11 engages with the driven gear 9 to rotate the driven gear 9, thereby driving the winding roller 10 to rotate. The rotation of the winding roller 10 causes the line 2 to be wound up or released, thereby adjusting the length of the line 2, so that the length of the optical fiber interface 1 jumper can be adjusted. The photoelectric signal conversion processing chip 19 is installed in the installation box 8 at the end of the line 3 7. When the optical signal reaches the installation box 8 through the optical fiber, the photoelectric signal conversion processing chip 19 converts it into an electrical signal. On the contrary, when the electrical signal is transmitted from the USB interface, the photoelectric signal conversion processing chip 19 converts it into an optical signal and transmits it through the optical fiber. The photoelectric signal conversion processing chip 19 converts the electrical signal transmitted from the USB interface into an optical signal and transmits it through the line 3 7. The photoelectric signal conversion processing chip 19 converts the optical signal transmitted from the optical fiber interface 1 into an electrical signal, and transmits the electrical signal to the terminal device through the USB interface body 22. The optical-electrical signal conversion processing chip 19 draws power from the terminal device through the USB interface body 22, and transmits the converted electrical signal to the terminal device through the USB interface body 22, and transmits the converted optical signal to the network device through the optical fiber interface 1. The rubber pad can increase the friction of the knob, so that the user feels better when rotating the knob and the operation is more comfortable. The optical fiber interface 1 is used to connect to the optical fiber panel socket 20 to realize the connection between the optical fiber jumper and the optical fiber network device or optical fiber panel, and realize the transmission of optical fiber signals.

[0026] Through the above steps, when the user rotates the knob 2 18, the knob drives the connecting rod 2 17 to rotate, and then drives the driving gear 2 16 to rotate. The driving gear 2 16 meshes with the driven gear 2 14, causing the driven gear 2 14 to rotate, thereby driving the two winding rollers 2 15 to rotate. The rotation of the winding roller 2 15 will drive the wire body 3 7 to be wound up or released, thereby adjusting the length of the entire jumper. The user can adjust the jumper length as needed to suit applications in different scenarios. When long-distance connections are not required, excess cables can be rolled up to avoid messy wiring. For applications where the wiring environment changes frequently, this structure can greatly improve the convenience and efficiency of wiring. At the same time, one rotation of the driving gear 2 16 can drive the driven gear 2 14 to rotate four times, thereby facilitating the user to quickly adjust the length of the jumper. Different ratios of the driving gear 2 16 and the driven gear 2 14 can be set according to needs to solve the problem that common optical fiber jumpers cannot be adjusted in length, easily resulting in a messy wiring environment, and excessively long cables may also become a safety hazard.
