Description

Technical Field

[0002] The insertion and return loss rapid testing device is a specialized testing equipment used to quickly detect the insertion loss and return loss of optical fiber connectors and optical modules in the field of optical communication. When an optical signal passes through the devices of a connector and coupler, the optical power is attenuated due to the absorption, reflection and scattering of the device itself. The smaller the value, the less the device attenuates the optical signal and the better its performance.

[0003] The multi-channel parallel insertion and return loss rapid testing device is a device used in the field of optical communication that can simultaneously and rapidly test the insertion loss and return loss of multiple channels of fiber optic connectors and optical modules. Through a multi-channel connection and high-speed sampling design, it can complete the insertion loss and return loss measurement of multiple channels in a short time. It can test multiple channels at the same time, which greatly improves the testing efficiency.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a multi-channel parallel insertion loss rapid testing device, comprising a fixed shell 1, with multiple connecting mechanisms 2 installed on the front side of the outer wall of the fixed shell 1 for quick connection of optical fibers, a heat dissipation mechanism 3 fixedly connected to the top of the inner wall of the fixed shell 1 for uniform heat dissipation, a display screen 4 installed on the top front side of the fixed shell 1, and a controller 5 installed on the right side of the outer wall of the display screen 4; the connecting mechanism 2 includes multiple connecting tubes 201, which are fixedly connected to the bottom front side of the fixed shell 1, with screws 202 threaded around the outer walls of the multiple connecting tubes 201, and connecting blocks 203 fixedly connected to the rear side of the outer walls of the connecting tubes 201, with multiple clamps fixedly connected to the middle of the inner wall of the connecting blocks 203. The top front side of the multiple connecting pipes 201 is rotatably connected to a cover plate 205. The front and rear sides of the outer wall of the connecting pipe 201 are fixedly connected to a fixing component 206. The fixing component 206 includes a fixing block 2061, which is fixedly connected to the top of the inner wall of the connecting pipe 201. A spring frame 2062 is fixedly connected to one side of the inner wall of the connecting pipe 201. The spring frame 2062 is fixedly connected to the rear side of the outer wall of the cover plate 205. The left and right sides of the middle part of the connecting pipe 201 are fixedly connected to a spring plate 2063.

A spring rod 2066 is slidably connected to one side of the bottom of the connecting sleeve 2064. A sealing ring 2065 is fixedly connected to the front end of the outer side of the connecting sleeve 2064.

[0034] Specifically, the working principle of the multi-channel parallel insertion and return loss rapid testing device revolves around fiber optic connection, insertion and return loss parameter testing, and stable equipment operation. Each mechanism works together to achieve rapid testing. When connecting the fiber, the cover plate 205 is first opened via the fixing component 206, and the spring frame 2062 deforms under force, causing the cover plate 205 to rotate. After inserting the fiber, the cover plate 205 is released, and the spring frame 2062 resets, closing the cover plate 205 and initially fixing the fiber. Simultaneously, the clamping piece 204 on the inner wall of the connecting block 203 adheres to the outer wall of the fiber, enhancing the fixing effect. The spring rod 2066 at the bottom of the connecting sleeve 2064 generates a reverse elastic force under the pressure of the fiber, which, in conjunction with the spring plate 2063... To ensure a stable connection, the sealing ring 2065 isolates dust and moisture. In addition, adjusting the screw 202 on the outer wall of the connecting tube 201 can reinforce the optical fiber, achieving a quick and stable connection. When the equipment is running, the heat dissipation mechanism 3 is fixed to the top of the inner wall of the fixed shell 1, absorbing and dissipating the heat inside the device to avoid excessive local temperature affecting the test accuracy and lifespan, ensuring stable operation of the device. The display screen 4 and controller 5 are responsible for the test human-machine interaction. The controller 5 receives instructions to control the test process, the test module detects the insertion and return loss parameters, and the data is transmitted to the display screen 4 in real time to be presented to the user. Through the collaboration of various mechanisms, the device can achieve rapid and accurate testing of multi-channel optical fiber insertion and return loss parameters.

[0035] Reference Figure 1 , Figure 2 and Figure 5The heat dissipation mechanism 3 includes a heat dissipation plate 301, which is fixedly connected to the top outer side of the fixed shell 1.

A fan blade 3052 is rotatably connected to the middle of the inner wall of the fixed pipe 3051. An exhaust pipe 3053 is connected to one side of the outer wall of the fixed pipe 3051. Multiple branch pipes 3054 are connected to the bottom outer side of the exhaust pipe 3053. A venting plate 3055 is rotatably connected to the left and right sides of the inner wall of the exhaust pipe 3053. The venting plate 3055 is slidably connected to the left and right sides of the middle part of the heat dissipation plate 301.

[0036] Specifically, the heat dissipation mechanism 3 undertakes the key heat dissipation task during device operation. The top of the outer side of the fixed shell 1 is fixedly connected to the heat dissipation plate 301. The heat dissipation holes 302 on the left and right sides of the top of the plate can exhaust the hot air inside the device. The middle rear side of the fixed shell 1 is fixedly connected to the partition plate 303. After the fan 304 on one side of the outer wall of the partition plate 303 is started, it accelerates the air flow inside the device and blows the heat towards the heat dissipation plate 301. The drive mechanism 305 on the top of the inner side of the heat dissipation plate 301 enhances the heat dissipation effect. The fan blades 3052 inside the fixed pipe 3051 rotate to generate airflow. The airflow is dispersed and transported through the exhaust pipe 3053 and multiple branch pipes 3054. At the same time, the air venting plates 3055 on the left and right sides of the inner wall of the exhaust pipe 3053 slide on the left and right sides of the middle of the heat dissipation plate 301 to adjust the airflow direction and range, so that the heat is discharged more evenly through the heat dissipation holes 302, effectively reducing the internal temperature of the device and ensuring the stable operation of the components. The insertion loss rapid test device is model JW3307A / B insertion loss tester.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Support legs 6 are fixedly connected to the four corners of the bottom of the fixed shell 1. Multiple sealing rings 7 are fixedly connected to the bottom rear side of the partition 303. A data hole 8 is slidably connected to the middle left side of the partition 303. A fixing ring 9 is installed in the middle of the inner wall of the data hole 8. Multiple bolts 11 are fixedly connected to the bottom of the inner wall of the fixed shell 1.

[0038] Specifically, during the operation of this structure, the four corner legs 6 at the bottom of the fixed shell 1 provide stable support, ensuring a stable foundation for the entire device and preventing easy shaking during operation. Multiple sealing rings 7 on the rear bottom side of the partition 303 tightly fit the relevant contact surfaces, effectively preventing external dust and moisture impurities from entering the device, ensuring a clean environment for internal components and reducing malfunctions caused by contamination. When data transmission or connection is required, the data hole 8 on the left side of the middle of the partition 303 can be flexibly adjusted for easy docking with external equipment. The fixing ring 9 in the middle of its inner wall... The data connector is fixed in place to prevent loose connections from affecting the stability of data transmission. Multiple bolts 11 on the bottom of the inner wall of the fixed housing 1 cooperate with the fixing buckles 10 connected to the threads on the left and right sides of the outer wall. By tightening the fixing buckles 10, the parts that need to be fixed can be locked onto the bolts 11, so as to achieve a stable installation of the internal components and prevent the parts from shifting during the operation of the device. The support plate 12 on the bottom left side of the fixed housing 1 provides a reliable mounting carrier for the cable guide 13. The cable guide 13 can organize and arrange the cables inside the device in an orderly manner, prevent the cables from getting tangled and messy, and ensure that the entire device works efficiently and stably.

[0039] Working Principle: The multi-channel parallel insertion and return loss rapid testing device operates on the principle of efficient fiber optic connection, accurate testing of insertion and return loss parameters, and stable equipment operation. Various mechanisms work together to achieve rapid testing. In the fiber optic connection stage, the connection mechanism 2 is the core. When connecting a fiber, the cover plate 205 is first opened via the fixing component 206. The spring frame 2062 deforms under force, causing the cover plate 205 to rotate around the top front side of the connecting tube 201. After inserting the fiber into the connecting tube 201, the cover plate 205 is released, and the spring frame 2062 resets, closing the cover plate 205 and initially fixing the fiber. Simultaneously, multiple clamping pieces 204 on the inner wall of the connecting block 203 tightly adhere to the outer wall of the fiber, further enhancing the fixing effect. The spring rod 2066 at the bottom of the connecting sleeve 2064 slides under the pressure of the fiber after insertion. The reverse elastic force, working in conjunction with the spring plate 2063, ensures the stability of the fiber optic connection. The sealing ring 2065 effectively isolates external dust and moisture, ensuring the cleanliness and dryness of the connection area. In addition, by adjusting the screw 202 on the outer wall of the connecting tube 201, the fiber optic cable can be further reinforced, achieving a quick and stable fiber optic connection. The display screen 4 and controller 5 are responsible for the human-machine interaction during the testing process. The controller 5 can receive user operation commands and control the testing process of the entire device. During the testing process, the internal testing module of the device will detect the insertion and return loss parameters of the fiber optic cable. The detected data will be transmitted to the display screen 4 in real time. The display screen 4 will present this data to the user in an intuitive way. The multi-channel parallel insertion and return loss rapid testing device realizes rapid and accurate testing of multi-channel fiber optic insertion and return loss parameters.

[0040] The heat dissipation mechanism 3 is fixedly connected to the top of the outer side of the fixed shell 1. The heat dissipation plate 301 is an important carrier for heat dissipation. The heat dissipation holes 302 on the left and right sides of its top can exhaust the hot air inside the device. The partition plate 303 fixedly connected to the middle rear side of the fixed shell 1 has a fan 304 on one side of its outer wall. When the fan 304 is started, it can accelerate the air flow inside the device and blow the heat towards the heat dissipation plate 301. The drive mechanism 305 on the top of the inner side of the heat dissipation plate 301 further enhances the heat dissipation effect. When the fan blade 3052 rotatably connected inside the fixed pipe 3051 rotates, it generates airflow. The airflow is dispersed and transported through the exhaust pipe 3053 and multiple branch pipes 3054. At the same time, the air venting plate 3055 rotatably connected to the left and right sides of the inner wall of the exhaust pipe 3053 slides on the left and right sides of the middle of the heat dissipation plate 301, which can adjust the direction and range of airflow, so that the heat is discharged more evenly through the heat dissipation holes 302, thereby effectively reducing the internal temperature of the device and ensuring that each component works stably at a suitable temperature.
