Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication technology, and in particular to an attenuator testing device. Background Technology
[0002] An attenuator is an electronic component or device used to reduce signal power or amplitude, widely used in communications and electronic measurement. To ensure the reliability of attenuators during use, several samples are tested before leaving the factory. Existing technologies, such as attenuator testing devices with patent applications 201420205127.2, 202321832762.9, and 201922014962.3, all test the attenuator's operation under stable conditions. However, for attenuators used in environments with frequent vibrations, such as those used in aviation or automotive applications, severe vibrations or impacts can cause fiber misalignment, attenuator plate displacement, or loosening of connecting components, leading to fluctuations in attenuation or optical path interruption. Therefore, attenuators used in vibrating environments must have vibration resistance. The aforementioned existing devices cannot detect the attenuator's operation under vibration conditions, resulting in inconvenience, poor practicality, and low reliability. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an attenuator testing device that can detect the light attenuation capability of an attenuator under vibration environment, which is easy to use, practical and highly reliable.
[0004] This utility model discloses an attenuator testing device, comprising a base plate and a support plate; it also includes an optical terminal device, optical fiber A, an optical power meter, optical fiber B, a vibration mechanism, and a clamping mechanism. The output end of the optical terminal device is provided with optical fiber A, which has a connector. The input end of the optical power meter is provided with optical fiber B, which also has a connector. The support plate is mounted on the base plate via the vibration mechanism, which vibrates the support plate. The clamping mechanism is mounted on the upper end of the support plate and has a clamping and fixing function. During attenuator testing, the attenuator is clamped and fixed by the clamping mechanism. Then, optical fiber A is connected to the input end of the attenuator, and optical fiber B is connected to the output end of the attenuator. The optical terminal equipment transmits the optical signal through a cooling plate to an attenuator. The attenuator then attenuates the optical signal, which is then transmitted to an optical power meter via fiber B. By comparing the power of the attenuated optical signal with the output power of the optical terminal equipment, the degree of attenuation can be determined. A vibration mechanism then causes the support plate to vibrate, which in turn causes the clamping mechanism to vibrate the attenuator. Observing the change in the received optical power on the optical power meter reveals whether the attenuator can maintain stable attenuation under vibration, thus judging its vibration resistance. This method is convenient to use and highly practical.
[0005] Preferably, the clamping mechanism includes a protective mechanism and a clamp. The protective mechanism is installed on the base plate, and the clamp is installed in the protective mechanism. The attenuator is clamped and fixed by the clamping mechanism. During the vibration of the attenuator, if the attenuator falls off, the protective mechanism prevents the attenuator from splashing to the outside, thus improving safety. The clamp can be a flat-jaw pliers or a four-jaw chuck.
[0006] Preferably, the protective mechanism includes a protective box and a sealing door. The protective box is fixedly installed on the upper end of the support plate. A chamber is provided inside the protective box, and an opening communicating with the chamber is provided at the front end of the protective box. The sealing door is installed on the outside of the opening. Through holes communicating with the chamber are provided on both the left and right sides of the protective box. The clamp is fixedly installed inside the chamber of the protective box. When testing the attenuator, the protective box and the sealing door prevent the attenuator from falling off the clamp and splashing into the external environment, thus improving reliability.
[0007] Preferably, the vibration mechanism includes a support column, a sliding column, a spring, and a vibration motor. The support column is fixedly installed on the upper end of the base plate, the lower part of the sliding column is slidably installed on the support column, a support plate is fixedly installed on the upper end of the sliding column, the lower end of the spring is fixedly installed on the base plate, the upper end of the spring is fixedly installed on the support plate, and the vibration motor is fixedly installed on the support plate. When the attenuator is vibrated, the vibration motor is turned on, and the inertial force generated by the vibration motor acts on the support plate, causing the support plate to vibrate up and down. This, in turn, causes the support plate to drive the protective box and the clamp to vibrate, and the clamp to drive the attenuator to vibrate, which facilitates the testing of the attenuation capability of the attenuator in a vibration environment.
[0008] Preferably, the protective box is equipped with a thermometer; this facilitates the monitoring of the temperature inside the protective box.
[0009] Preferably, an electric heating lamp is installed inside the protective box, and a cooling plate is installed on the protective box. The cooling end of the cooling plate is located inside the protective box, and the heat dissipation end of the cooling plate is located outside the protective box. Since thermal expansion and contraction will affect the performance of the attenuator inside the attenuator, the temperature inside the protective box can be adjusted by the electric heating lamp or the cooling plate, thereby enabling the attenuation capability of the attenuator at different temperatures, which improves convenience.
[0010] Preferably, the sealed door is provided with an observation window; this feature facilitates the monitoring of the working status of the attenuator inside the protective enclosure.
[0011] Compared with the prior art, the advantages of this utility model are: it can detect the light attenuation capability of the attenuator under vibration environment, it is convenient to use, and has high practicality and reliability. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example
[0019] like Figures 1 to 5The attenuator testing device of this utility model includes a base plate 1, a support plate 2, an optical fiber terminal device 3, an optical fiber A4, an optical power meter 5, an optical fiber B6, a vibration mechanism, and a clamping mechanism. The output end of the optical fiber terminal device 3 is provided with optical fiber A4, and a connector is provided on optical fiber A4. The input end of the optical power meter 5 is provided with optical fiber B6, and a connector is provided on optical fiber B6. The support plate 2 is mounted on the base plate 1 via the vibration mechanism, which vibrates the support plate 2. The clamping mechanism is mounted on the upper end of the support plate 2 and has a clamping and fixing function. When testing the attenuator 15, the attenuator 15 is clamped and fixed by the clamping mechanism. Then, optical fiber A4 is connected to the input end of the attenuator 15, and optical fiber B6 is connected to the output end of the attenuator 15. The optical terminal device 3 is turned on, and the optical signal is transmitted to the attenuator 15 through the cooling plate 14. The attenuator 15 then attenuates the optical signal, and the attenuated signal is transmitted to the optical power meter 5 through the optical fiber B6. By comparing the power of the attenuated optical signal with the output power of the optical signal at the optical terminal device 3, the degree of attenuation of the optical signal by the attenuator 15 can be determined. Then, the support plate 2 is vibrated by the vibration mechanism, which in turn causes the clamping mechanism to drive the attenuator 15 to vibrate. After that, the optical power received on the optical power meter 5 is observed to see if there is a change, so as to know whether the attenuator 15 can maintain a stable attenuation capability of light under vibration environment, and thus judge the vibration resistance of the attenuator 15. It is convenient to use and highly practical.
[0020] like Figure 1 and Figure 4 The clamping mechanism includes a protective mechanism and a clamp 7. The protective mechanism is installed on the base plate 1, and the clamp 7 is installed in the protective mechanism. The attenuator 15 is clamped and fixed by the clamping mechanism. During the vibration of the attenuator 15, if the attenuator 15 falls off, the protective mechanism will prevent the attenuator 15 from splashing to the outside, thus improving safety. The clamp 7 can be a flat-jaw pliers or a four-jaw chuck.
[0021] like Figure 1 The protective mechanism includes a protective box 8 and a sealing door 9. The protective box 8 is fixedly installed on the upper end of the support plate 2. A chamber is provided inside the protective box 8. An opening communicating with the chamber is provided at the front end of the protective box 8. The sealing door 9 is installed on the outside of the opening. Through holes communicating with the chamber are provided on both the left and right sides of the protective box 8. The clamp 7 is fixedly installed inside the chamber of the protective box 8. When testing the attenuator 15, the attenuator 15 is prevented from splashing into the external environment after falling off the clamp 7 by the shielding of the protective box 8 and the sealing door 9, thus improving reliability.
[0022] like Figure 3The vibration mechanism includes a support column 10, a sliding column 11, a spring 12, and a vibration motor 13. The support column 10 is fixedly installed on the upper end of the base plate 1. The lower part of the sliding column 11 is slidably installed on the support column 10. The support plate 2 is fixedly installed on the upper end of the sliding column 11. The lower end of the spring 12 is fixedly installed on the base plate 1, and the upper end of the spring 12 is fixedly installed on the support plate 2. The vibration motor 13 is fixedly installed on the support plate 2. When the attenuator 15 is vibrated, the vibration motor 13 is turned on. The inertial force generated by the vibration motor 13 acts on the support plate 2, causing the support plate 2 to vibrate up and down. This, in turn, causes the support plate 2 to drive the protective box 8 and the clamp 7 to vibrate, which in turn causes the clamp 7 to drive the attenuator 15 to vibrate. This facilitates the testing of the attenuation capability of the attenuator 15 under vibration.
[0023] A thermometer is installed on the protective box 8; this feature facilitates the monitoring of the temperature inside the protective box 8.
[0024] An observation window is provided on the sealed door 9; this feature facilitates the monitoring of the working status of the attenuator 15 inside the protective box 8. Example
[0025] Based on Example 1, an electric heating lamp is installed inside the chamber of the protective box 8, and a cooling plate 14 is installed on the protective box 8. The cooling end of the cooling plate 14 is located inside the chamber of the protective box 8, and the heat dissipation end of the cooling plate 14 is located outside the protective box 8. Since thermal expansion and contraction will affect the performance of the attenuation plate inside the attenuator 15, the temperature inside the chamber of the protective box 8 can be adjusted by the electric heating lamp or the cooling plate 14, thereby enabling the attenuation capability of the attenuator 15 at different temperatures, which improves convenience.
[0026] The optical terminal device 3, optical power meter 5, spring 12, vibration motor 13, electric heating lamp and cooling plate of the attenuator testing device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
