Description

Technical Field

[0001] This utility model relates to the field of optical cable repair technology, specifically to an optical cable fault diagnosis device identified by an OTDR. Background Technology

[0002] An OTDR (Optical Time Domain Reflectometer) is an important testing instrument widely used in fiber optic communication. Based on the principles of backscattering and Fresnel reflection, it works by emitting light pulses into the optical fiber and detecting the returned backscattered signal to comprehensively evaluate the fiber. It can measure key parameters such as fiber length, attenuation coefficient, splice loss, and the location of fiber faults, helping technicians understand the fiber's transmission performance and physical condition. It plays a crucial role in the construction, maintenance, and troubleshooting of fiber optic lines, effectively ensuring the stable and efficient operation of fiber optic networks.

[0003] Chinese patent CN222638535U discloses a fiber optic patch cord fault diagnosis device. This device, through the setting of the optical energy plate mechanism, can replenish the power of the tester's internal battery. When testing outdoor cables and some remote areas far from the power source, it has the characteristics of good continuous power supply, effectively avoiding the bulky and difficult-to-carry situation of traditional energy storage batteries. It is mostly used for operations with insufficient power during the diagnosis process. It has a simple structure and long battery life.

[0004] However, the tester and the solar panel mechanism in the above patent are separate structures, which means that while carrying the tester, the solar panel mechanism also needs to be carried separately. This not only takes up space in both hands, but also increases the overall carrying burden. In addition, the solar panel mechanism is easy to forget or lose, which is quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide an OTDR-identified optical cable fault diagnosis device, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] An OTDR-based optical cable fault diagnosis device includes a tester body. A receiving groove is provided on the rear side of the tester body, and a solar panel is disposed inside the receiving groove. Both sides of the upper end of the solar panel are rotatably connected to the inner wall of the receiving groove via damping shafts. An electric slip ring is mounted on the outer surface of the damping shaft. The input end of the electric slip ring is electrically connected to the solar panel, and the output end of the electric slip ring is electrically connected to a battery inside the tester body via a wire.

[0008] Therefore, by placing the solar panel on the rear side of the testing instrument, the two are integrated into one unit. Staff only need to carry one device, making movement more flexible and avoiding the loss of parts. Furthermore, the damping shaft allows the solar panel to be flipped, thus adjusting its angle to adapt to sunlight and improving power generation efficiency.

[0009] Furthermore, two slide rails are symmetrically installed on the rear side of the tester body, and a baffle is slidably installed inside the two slide rails. Two insertion holes are opened on the upper and lower sides of the rear side of the tester body, and a fixing mechanism that engages with the insertion holes is provided on the side of the baffle facing the tester body.

[0010] Furthermore, the fixing mechanism includes a horizontal plate disposed on the surface of the baffle, with insert rods installed on both sides of the outer surface of the horizontal plate, the insert rods being adapted to insert holes. A guide rod is connected to the side of the horizontal plate facing the baffle, and the end of the guide rod slides through to the other side of the baffle and is fitted with a pull block.

[0011] Furthermore, a spring is fitted onto the outer surface of the guide rod, with the two ends of the spring abutting against the horizontal plate and the baffle, respectively.

[0012] Furthermore, a limiting rod is connected to the surface of the horizontal plate facing the baffle, and the end of the limiting rod slides through to the other side of the baffle.

[0013] Furthermore, a first rubber pad is provided inside the receiving groove.

[0014] Furthermore, a second rubber pad is provided on the outer surface of the cross plate, and the second rubber pad corresponds to the first rubber pad.

[0015] Furthermore, the front side of the tester body is equipped with a display screen and control buttons, the top of the tester body is equipped with a wiring hole, and a dust cover is rotatably installed on the top of the tester body outside the wiring hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model integrates the solar panel into a single unit by placing it on the rear side of the testing instrument body. This allows staff to carry only one device, making movement more convenient and preventing the loss of parts. Furthermore, the damping shaft enables the solar panel to rotate, allowing its angle to be adjusted to suit sunlight and improve power generation efficiency.

[0018] 2. By setting up a baffle, this utility model allows the solar panel to be stored in the receiving groove when not in use, and the baffle covers the outside of the solar panel for protection, preventing the solar panel from being damaged by external forces. When the solar panel is stored inside the receiving groove, its two sides are clamped by the first rubber pad and the second rubber pad respectively, thereby preventing the receiving groove from shaking and colliding with the inner wall of the receiving groove and the baffle, further improving the protection of the solar panel.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This utility model provides an OTDR-based optical cable fault diagnosis device, comprising a tester body 1. A receiving groove 101 is provided on the rear side of the tester body 1. A solar panel 102 is disposed inside the receiving groove 101. Both sides of the upper end of the solar panel 102 are rotatably connected to the inner wall of the receiving groove 101 via damping shafts 103. An electric slip ring 104 is mounted on the outer surface of the damping shaft 103. The input end of the electric slip ring 104 is electrically connected to the solar panel 102, and the output end of the electric slip ring 104 is electrically connected to a battery inside the tester body 1 via a wire 105.

[0029] When it is necessary to power the battery inside the tester body 1, the solar panel 102 can be rotated out from the inside of the receiving slot 101 and adjusted to a suitable angle. Due to the damping property of the damping shaft 103, the solar panel 102 can remain fixed after the angle is adjusted. After the solar panel 102 is exposed to the sun, it converts solar energy into electrical energy and stores it in the battery inside the tester body 1 through the wire 105, thereby achieving the purpose of continuous power supply and improving the battery life.

[0030] Furthermore, by placing the solar panel 102 on the rear side of the tester body 1, the two are integrated into one unit, allowing staff to carry only one device, making movement more flexible and avoiding the loss of parts, thus making it more convenient to use.

[0031] It is worth noting that the tester body 1 is existing technology, mainly comprising a transmitting module, a receiving module, and a data processing module. The transmitting module generates light pulses of specific wavelength and power as the "signal source" for optical cable testing. The receiving module receives the light signals reflected from the optical cable and converts them into electrical signals for processing. The data processing module analyzes and processes the received electrical signals, calculates information such as the time and intensity of the reflected signal, and plots an OTDR curve based on this information. By analyzing the OTDR curve, the location, type, and severity of the optical cable fault can be determined. Since the tester body 1 is existing technology, it will not be described in detail here.

[0032] Preferably, two slide rails 2 are symmetrically installed on the rear side of the tester body 1, and a baffle 201 is slidably installed inside the two slide rails 2. Two insertion holes 106 are opened on the upper and lower sides of the rear side of the tester body 1, and a fixing mechanism 3 is provided on the side of the baffle 201 facing the tester body 1 to engage with the insertion holes 106.

[0033] By setting the baffle 201, the solar panel 102 can be stored in the receiving slot 101 and its exterior can be blocked to prevent the solar panel 102 from being damaged by external forces. Furthermore, by the insertion and cooperation of the fixing mechanism 3 and the socket 106, the position of the baffle 201 can be fixed to prevent the baffle 201 from shaking or being lost during the carrying of the test instrument body 1.

[0034] Preferably, the fixing mechanism 3 includes a horizontal plate 301 disposed on the surface of the baffle 201. Insert rods 302 are installed on both sides of the outer surface of the horizontal plate 301, and the insert rods 302 are adapted to the insertion holes 106. A guide rod 303 is connected to the side of the horizontal plate 301 facing the baffle 201, and the end of the guide rod 303 slides through to the other side of the baffle 201 and is fitted with a pull block 304.

[0035] By inserting the rod 302 on the horizontal plate 301 into the insertion hole 106, and with the limiting effect of the slide rail 2 on the baffle 201, the baffle 201 can be fixed. When the pull block 304 is pulled to move the horizontal plate 301 and the rod 302 is pulled out from the insertion hole 106, the baffle 201 can be released and the baffle 201 can slide up and down in the slide rail 2.

[0036] Preferably, a spring 4 is sleeved on the outer surface of the guide rod 303, and the two ends of the spring 4 abut against the horizontal plate 301 and the baffle 201 respectively.

[0037] By setting the spring 4, a continuous and stable pushing force can be applied to the horizontal plate 301, ensuring that the insertion rod 302 can be stably inserted into the insertion hole 106, thus ensuring the fixing effect of the baffle 201.

[0038] Preferably, a limiting rod 5 is connected to the surface of the horizontal plate 301 facing the baffle 201, and the end of the limiting rod 5 slides through to the other side of the baffle 201.

[0039] By setting the limiting rod 5, the angle of the horizontal plate 301 can be limited, ensuring that the horizontal plate 301 is always in a horizontal position, thereby improving the insertion effect of the insertion rod 302 and the insertion hole 106.

[0040] Preferably, a first rubber pad 6 is provided inside the receiving groove 101.

[0041] When the solar panel 102 is closed in the receiving groove 101, the first rubber pad 6 can act as a buffer when in contact with the solar panel 102, reducing the impact force and preventing the solar panel 102 from colliding directly with the inner wall of the receiving groove 101 and causing damage.

[0042] Preferably, a second rubber pad 601 is provided on the outer surface of the horizontal plate 301, and the second rubber pad 601 corresponds to the first rubber pad 6.

[0043] When the spring 4 pushes the insertion rod 302 into the insertion hole 106, it not only fixes the baffle 201, but also presses the second rubber pad 601 on the outer surface of the solar panel 102. Since the solar panel 102 is installed through the damping shaft 103 and has the ability to rotate, the clamping action of the first rubber pad 6 and the second rubber pad 601 on both sides of it prevents the receiving groove 101 from shaking and colliding, thus further improving the protection of the solar panel 102.

[0044] Preferably, the front side of the tester body 1 is provided with a display screen 107 and control buttons 108, the top of the tester body 1 is provided with a wiring hole 109, and a dust cover 110 is rotatably installed on the top of the tester body 1 and outside the wiring hole 109.

[0045] By inserting the fiber optic connector into the wiring hole 109, data can be displayed on the screen 107 and controlled via the control button 108. When operating outdoors, while the solar panel 102 is generating electricity, the insertion rod 302 can be inserted into the upper insertion hole 106, at which point the baffle 201 is fixed above. Figure 3 As shown, this can serve as a sunshade, reducing the reflection of the display screen 107 caused by sunlight.

[0046] Furthermore, when the wiring hole 109 is not in use, it can be covered with a dust cover 110 to prevent dust and impurities from entering the wiring hole 109 and affecting the accuracy of the data.

[0047] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
