Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, in particular to an optical fiber probe docking device. Background Art

[0002] An optical fiber temperature sensor is a sensing device that is sensitive to temperature based on optical fiber technology and changes in the physical properties of light, and is used for real-time monitoring and measurement of temperature. It uses optical fiber as the signal transmission medium and reflects the temperature of the measured environment or object by changes in optical parameters such as the intensity, phase, wavelength, or frequency of light.

[0003] As an important component structure of the optical fiber temperature sensor, the optical fiber probe plays an important role in temperature detection. Generally speaking, the optical fiber probe needs to form a path between the temperature measurement point and the collector, that is, there is no disconnection between the optical fiber probe and the extension cable. Usually, the optical fiber temperature sensor is divided into an integrated type and a split type. For equipment with a layered cover structure, during the installation of the optical fiber temperature sensor, the probe of the integrated optical fiber temperature sensor is installed on the upper part of the cover-type equipment, and the extension cable penetrates into the lower part of the cover-type equipment and is connected to the jumper using a standard connector. However, when the upper and lower parts of the cover-type equipment are covered, due to the force during the covering of the upper and lower parts of the cover-type equipment, the optical fiber in the probe and the extension cable is extremely easy to break, resulting in the inability to form an optical fiber loop between the probe and the jumper and unable to perform accurate temperature feedback.

[0004] Therefore, it is necessary to provide a split-type optical fiber probe docking device to solve the above problems existing in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an optical fiber probe docking device, which forms a split structure with the probe and is respectively installed on the upper and lower parts of the cover-type equipment, so that an optical fiber path can be formed between the probe and the jumper, thereby accurately feeding back the temperature of the cover-type equipment.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] An optical fiber probe docking device includes:

[0008] A fixing member, which is provided with a mounting hole;

That is, in the working state, the probe penetrates into the installation hole of the fixing member, is centered by the centering member, and is connected to one end of the optical fiber in the protection member. The other end of the optical fiber is connected to the jumper wire, so that an optical fiber loop is formed between the probe and the jumper wire through the optical fiber probe docking device, which can accurately feedback the temperature condition of the device to be temperature-measured. At the same time, if the sensor needs to be replaced, only the probe needs to be replaced, and the jumper wire can be retained or replaced according to specific requirements.

[0013] Furthermore, it further includes an elastic element; the centering member and the protection member are movably arranged in the installation hole; the elastic element is located in the installation hole and is used to apply a force towards the top of the fixing member to the centering member and the protection member. The beneficial effect is that by designing the elastic element in the installation hole, it ensures good docking between the optical fiber of the probe and the optical fiber of the optical fiber probe docking device of the present utility model, and avoids damage to the optical fiber interface due to rigid contact.

[0014] Furthermore, a first step is formed between the bottom of the centering member and the side wall of the protection member, a second step is provided in the installation hole, the elastic element is sleeved on the protection member, and one end of the elastic element abuts against the first step and the other end abuts against the second step.

[0016] Furthermore, the centering member is provided with a centering hole, and the centering hole is communicated with the first connection hole, so that the optical fiber is exposed from the centering hole.

[0017] Furthermore, it further includes a heat shrinkable tube, and the protection member is nested in the heat shrinkable tube. The beneficial effect is that on the one hand, the heat shrinkable tube can protect the optical fiber outside the protection member, and on the other hand, it can prevent the elastic element from falling off.

[0018] Further, a third step away from the top of the fixing member is also provided in the mounting hole, and one end of the heat shrinkable tube is clamped to the third step.

Detailed Embodiments

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present utility model pertains. The words such as "including" used herein are intended to mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0029] The following further elaborates on the specific implementation manners of the present utility model in conjunction with the accompanying drawings.

[0030] As Figures 1-5 shown, an embodiment of the present utility model provides an optical fiber probe docking device 100, including: a fixing member 1, an orienting member 2, a protecting member 3, and an optical fiber 4. The fixing member 1 is used to fixedly install the optical fiber probe docking device 100 on a device to be measured and serves as a carrier for the orienting member 2, the protecting member 3, and the optical fiber 4. The protecting member 3 is used to protect and accommodate the optical fiber 4. The orienting member 2 is used to align the optical fiber 4 in the probe and the protecting member 3. The optical fiber 4 is used to connect with the probe and the jumper to form an optical fiber path.

[0031] The fixing member 1 is provided with an installation hole 11 for installing the orienting member 2 and the protecting member 3. The orienting member 2 is disposed in the installation hole 11 and is used to collimate the probe 200 penetrating into the installation hole 11. The protecting member 3 is detachably connected to the orienting member 2, that is, both the protecting member 3 and the orienting member 2 are disposed in the installation hole 11 in the connected state. The optical fiber 4 is disposed in the protecting member 3. One end of the optical fiber 4 is used to connect with the probe 200, and the other end is used to connect with the jumper, so that the probe 200 and the jumper form a path through the optical fiber 4. For example, the upper end of the optical fiber 4 is connected to the probe 200, and the lower end is connected to the jumper.

[0032] By designing the orienting member 2 and the protecting member 3 to be detachably connected, they can be replaced according to the specific structure of the probe 200, that is, designing orienting members 2 and protecting members 3 with different sizes to adapt to different probes 200, with strong adaptability.

[0033] Compared with the integrated structure of the optical fiber probe, by designing the optical fiber probe docking device 100 and the probe 200 as a split structure and installing them on the upper and lower parts of the device to be temperature measured, such as a cover-type device, through the closing of the upper and lower parts, that is, relying on the structural characteristics of the cover-type device itself to cover, the optical fiber 4 of the optical fiber probe docking device 100 and the probe 200 can be accurately docked without an extension cord and without causing breakage of the probe 200, and a complete optical fiber loop can be formed to input or output relevant signals for temperature measurement work.

[0034] As Figures 2-4 shown, in some embodiments of the present invention, the optical fiber probe docking device 100 further includes an elastic element 5. The orienting member 2 and the protecting member 3 are movably disposed in the mounting hole 11. The elastic element 5 is located in the mounting hole 11 and is used to apply a force towards the top of the fixing member 1 to the orienting member 2 and the protecting member 3, so that the orienting member 2 and the protecting member 3 can be reset after moving in the mounting hole 11.

[0035] During installation, the probe 200 is inserted into the mounting hole 11 and contacts the orienting member 2. The force applied by abutting against the orienting member 2 causes the orienting member 2 to move downward, and at the same time drives the protecting member 3 to move downward, that is, the orienting member 2 and the protecting member 3 form a movable assembly. At this time, the elastic element 5 located in the mounting hole 11 is compressed; when the probe 200 is removed from the mounting hole 11, the elastic element 5 returns to its initial state, so that the orienting member 2 and the protecting member 3 are reset.

[0036] Since the probe 200 and the optical fiber probe docking device 100 are respectively installed on the upper and lower parts of the device to be temperature measured, when the upper and lower parts are closed, on the one hand, due to installation errors, by designing the elastic element 5 in the optical fiber probe docking device with a large elastic range, the errors are avoided; on the other hand, the elasticity of the elastic element 5 can buffer the force after, for example, the upper part presses down the probe 200 and penetrates into the mounting hole 11, so that the probe 200 and the optical fiber 4 are better docked and fitted, ensuring that the probe 200 and the optical fiber 4 form an optical fiber loop for temperature measurement work on the device to be temperature measured.

[0037] As Figure 4 shown, in some embodiments of the present invention, a first step 111 is formed between the bottom of the orienting member 2 and the side wall of the protecting member 3, that is, the connection between the orienting member 2 and the protecting member 3 constitutes the first step 111. A second step 112 is provided in the mounting hole 11. The distance between the first step 111 and the second step 112 is the length of the elastic element 5 in its initial state. The elastic element 5 is sleeved on the protecting member 3, and one end of the elastic element 5 abuts against the first step 111 and the other end abuts against the second step 112. For example, the elastic element 5 is a spring.

[0038] As Figure 3As shown, in some embodiments of the present utility model, the optical fiber 4 includes a wiring section 41 and a mounting section 42. The protective member 3 includes a first connection hole and a second connection hole that are in communication. The wiring section 41 is disposed in the first connection hole, and the mounting section is disposed in the second connection hole. For example, the mounting section 42 of the optical fiber 4 is fixedly installed in the second connection hole of the protective member 3 by means of a threaded connection.

[0039] As Figures 3-4 shown, in some embodiments of the present utility model, the orienting member 2 is provided with an orienting hole 21. The orienting hole 21 is in communication with the first connection hole, such that the optical fiber 4 is exposed in the orienting hole 21. When the probe 200 penetrates into the mounting hole 11, the probe 200 is aligned with the optical fiber 4 exposed in the orienting hole 21 through the orienting hole 21 of the orienting member 2.

[0040] As Figures 1-3 shown, in some embodiments of the present utility model, the optical fiber probe docking device 100 further includes a heat shrinkable tube 6. The protective member 3 is nested within the heat shrinkable tube 6. That is, the protective member 3 is installed within the heat shrinkable tube 6 in a nested manner.

[0041] As Figures 3-4 shown, in some embodiments of the present utility model, a third step 113 is further provided in the mounting hole 11 away from the top of the fixing member 1. One end of the heat shrinkable tube 6 is snap-fitted to the third step 113. That is, the heat shrinkable tube 6 is snap-fitted to the lower end of the fixing member 1 through the provision of the third step 113, and the upper end of the heat shrinkable tube 6 covers the lower port of the mounting hole 11 and abuts against the lower end surface of the mounting hole 11. In this way, the elastic element 5 can be prevented from falling off. For example, the heat shrinkable tube 6 is a silicone heat shrinkable tube.

[0042] As Figures 1-3 shown, in some embodiments of the present utility model, the optical fiber probe docking device 100 further includes a quick connector 7. One end of the quick connector 7 is connected to the other end of the optical fiber 4, and the other end of the quick connector 7 is for connection to a jumper. That is, the upper end of the quick connector 7 is connected to the lower end of the optical fiber 4, and the lower end of the quick connector 7 is connected to the jumper, so that the optical fiber 4 is in communication with the jumper. When the probe 200 penetrates into the mounting hole 11, the probe 200 is connected to the upper end of the optical fiber 4 within the protective member 3, and the lower end of the optical fiber 4 is connected to the jumper, thereby forming a complete optical fiber loop, and thus the temperature of the device to be temperature-measured can be measured and the temperature value of the device can be accurately fed back.

[0043] Specifically, the quick connector 7 is an ST connector or an SMA connector or an FC connector. That is, the quick connector 7 is selected as a standard connector for connection to the jumper. It should be noted that there is no specific limitation on the specific type of the quick connector 7, and the specific type is selected according to the actual usage situation.

[0044] As Figure 1As shown, in some embodiments of the present utility model, the opposite ends of the fixing member 1 are further provided with a first through hole 12 and a second through hole 13 for connecting with the device to be temperature measured. Specifically, the first through hole 12 and the second through hole 13 are respectively located on both sides of the mounting hole 11. The optical fiber probe docking device 100 of the present utility model is mounted on the end face of the device to be temperature measured through the first through hole 12 and the second through hole 13. For example, bolts are respectively inserted into the first through hole 12 and the second through hole 13 to fasten the optical fiber probe docking device 100 to the device to be temperature measured.

[0045] As Figure 1 shown, in some embodiments of the present utility model, the fixing member 1 further includes a boss 14 and a flange 15 connected to the boss 14. The boss 14 and the flange 15 can be designed as a split structure or an integral structure. The mounting hole 11 penetrates through the boss 14 and the flange 15. Specifically, the mounting hole 11 penetrates along the central axis of the boss 14 and the flange 15. The first through hole 12 and the second through hole 13 are respectively provided at the opposite ends of the flange 15. When the optical fiber probe docking device 100 is installed with the lower part of the cover plate type device through the first through hole 12 and the second through hole 13, the flange 15 is in contact with the end face of the lower part. It should be noted that the structure of the fixing member 1 is not specifically limited.

[0046] As Figures 3-4 shown, in some embodiments of the present utility model, the upper end of the protection member 3 is provided with an external thread portion, and the lower end of the orientation member 2 is provided with an internal thread portion. The orientation member 2 and the protection member 3 are installed by screwing the external thread portion and the internal thread portion. This detachable connection method has a simple structure, reliable connection and convenient disassembly. For example, the orientation member 2 is a hollow cylindrical shape, and the protection member 3 is also a hollow cylindrical shape. Since the shaft diameter of the upper end of the protection member 3 is smaller than the shaft diameter of the lower end of the orientation member 2, a first step 111 is formed after the lower end of the orientation member 2 is threadedly connected to the protection member 3.

[0047] The orientation member 2, the protection member 3 and the elastic element 5 are all installed in the mounting hole 11 of the fixing member 1. During the docking installation process of the probe 200 and the optical fiber probe docking device 100, the settings of the orientation member 2, the protection member 3, the optical fiber 4 and the heat shrinkable tube 6 ensure the collimation during the docking process, and the elastic element 5 ensures the contact surface between the probe 200 and the optical fiber 4 is in contact, thereby forming a complete optical fiber path. The orientation member 2, the protection member 3, the optical fiber 4 and the heat shrinkable tube 6 can be adjusted according to the external dimension of the probe 200 to ensure the temperature measurement performance of the probe after docking and adapt to the equipment environment for use.

[0048] If standard connectors currently in existence such as SMA / ST / FC are used, the probe 200 needs to be used with an extension cable, that is, a probe 200 with an integrated structure needs to be used. When using an integrated probe, the extension cable needs to extend from inside the device to outside the device for manual plugging and unplugging operations. However, when the probe 200 still needs to be docked with a jumper without being equipped with an extension cable, due to factors such as temperature or space constraints, such standard connectors cannot be used, and manual operation is inconvenient. Therefore, the split structure of the optical fiber probe docking device 100 and the probe 200 of the present utility model is adopted, eliminating the need for an extension cable. When applicable to a cover-type device, it will not cause the probe 200 to break. The optical fiber probe docking device 100 connects the probe 200 and the jumper to form an optical fiber loop, thereby performing temperature measurement work.

[0049] As Figure 5 shown and with reference to Figure 1 , for a device to be temperature-measured such as a cover-type device, the steps for using the split structure of the optical fiber probe docking device 100 and the probe 200 of the present utility model are as follows:

[0050] First, install the probe 200 and the optical fiber probe docking device 100 on the upper and lower parts of the cover-type device respectively; then press the upper part of the cover-type device down onto the lower part or make the lower part fit the upper part. At this time, when the probe 200 passes through the mounting hole 11 and approaches the orienting member 2, a downward force is generated on the orienting member 2, driving the protective member 3 to move downward. At this time, the elastic element 5 is compressed and the optical fiber 4 of the probe 200 is aligned and in contact with the optical fiber probe docking device 100; then connect the quick connector 7 to the jumper, thereby forming an optical fiber transmission loop between the probe 200 and the jumper through the optical fiber 4 to perform temperature measurement on the cover-type device; after the temperature measurement work is completed, remove the probe 200 from the mounting hole 11, and the elastic element 5 returns to its initial position. At this time, the orienting member 2 and the protective member 3 are reset to their initial states.

[0051] The present utility model designs the traditional integrated optical fiber probe structure into a split structure of the probe 200 and the optical fiber probe docking device 100. The probe 200 is installed on the end face of the upper part of the device to be temperature-measured, and the optical fiber probe docking device 100 is installed on the end face of the lower part of the device to be temperature-measured. One end of the optical fiber probe docking device 100 is connected to the probe 200, and the other end is connected to the jumper to form an optical fiber loop. At the same time, when installing the optical fiber probe docking device 100 and the probe 200, only the upper and lower parts of the device to be temperature-measured need to be closed, eliminating the need for manual plugging and unplugging operations, saving manpower, and this docking method can adapt to various installation environments, with stronger adaptability.

[0052] It should be noted that the upper and lower herein refer to Figure 3 the upper and lower as shown.

[0053] It should be emphasized that in this article, a cover-type device is taken as an example. The fiber optic probe docking device of the present utility model is applicable not only to the stacked cover-type devices, but also to the temperature detection of integrated devices. There is no restriction on the installation environment, with stronger flexibility and wider adaptability.

[0054] In the prior art, an optical fiber adapter is used to connect the two ends of the optical fiber, and a corresponding adapter installation space needs to be reserved at the docking position. When there is insufficient space inside the device or the end of the temperature sensing probe cannot be installed with a pin, a new optical fiber docking device needs to be designed to complete the optical fiber docking so that the temperature sensor works properly. Although the prior art can meet the optical fiber alignment, in special installation environments, such as: the temperature measuring probe requires independence and there is no extension cable; there is no fixed position for the adapter on the device; the material cannot meet the requirements of the use environment, etc., the prior art cannot meet the use requirements. Therefore, when the existing standard optical fiber docking parts cannot be used, it is necessary to design a temperature measuring probe docking device according to the actual device use environment and installation space.

[0055] In summary, for the environment where the optical fiber adapter cannot be used, to better serve the temperature measurement of the environment to be measured, the present utility model can be specifically customized according to the specific structure of the probe and the structure of the device to be temperature measured by designing the structures of the fixing part, the orienting part, the protecting part and the optical fiber. Specifically, through the design of the fixing part, it is convenient to fixedly install the fiber optic probe docking device on the device to be temperature measured. Compared with the traditional docking method of the probe, the extension cable and the standard connector, there is no need to use the extension cable and the standard connector. The fiber optic probe docking device of the present utility model replaces the extension cable and the standard connector, saving the part cost. That is, in the working state, one end of the fiber optic probe docking device is connected to the probe, and the other end is connected to the jumper wire, thus forming an optical fiber loop to accurately feedback the temperature condition of the device to be temperature measured. At the same time, if the sensor needs to be replaced, only the probe needs to be replaced, and the jumper wire can be reserved or replaced according to specific requirements. The fiber optic probe docking device of the present utility model can adapt to different types of probes, is flexible in application, is applicable to various scenarios where the probe and the jumper wire need to be docked, is convenient to use, simple to install, and has strong adaptability.

[0056] Although the embodiments of the present utility model have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present utility model described in the claims. Moreover, the present utility model described herein can have other embodiments and can be implemented or realized in various ways.
