Description

Technical Field

[0001] This utility model relates to the field of optical power meter technology, and in particular to a multifunctional optical power meter housing and an optical power meter. Background Technology

[0002] In fiber optic communication systems, optical power meters are indispensable measuring tools used to measure optical power levels at specific wavelengths. Optical power meters can measure absolute optical power or the relative loss of optical power passing through a section of optical fiber, and are one of the important parameters for evaluating the performance of optical terminal equipment and assessing the quality of fiber optic transmission. However, existing optical power meters have certain functional limitations, which to some extent restricts their convenience and widespread use in practical applications.

[0003] Existing optical power meters mainly focus on the direct and relative measurement of optical power, but in actual use, users often need to bring other testing equipment to complete more testing tasks.

[0004] For example, when conducting fiber optic connection tests, users need to carry not only an optical power meter but also a device for testing the pairing and crimping of network cables. These additional testing devices increase the burden on users. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a multifunctional optical power meter housing and an optical power meter, which can solve the problem that the optical power meter has only one function and can only perform optical power detection.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A multifunctional optical power meter housing, comprising:

[0008] The outer casing body is provided with a display screen, a red light emitting head, an optical power detection head, a first line sequence indicator light, and a first interface for line detection and line crimp detection. The display screen and the first line sequence indicator light are both located on one side of the outer casing body, the red light emitting head and the optical power detection head are both located on the top of the outer casing body, and the first interface is located on one side of the outer casing body.

[0009] The remote receiver is provided with a second wiring indicator and a second interface for receiving the wiring signal emitted by the first interface.

[0010] By adopting the above scheme, the first interface provides the basis for wire crimping and wire pairing detection, allowing users to complete multiple testing tasks on the same device, greatly improving the device's practicality. The second interface is designed to complete the remote connection during wire pairing, facilitating synchronous testing from different locations and ensuring the accuracy of the network cable connection. The first wire sequence indicator displays the network cable sequence at the first interface, helping users quickly identify and confirm the sequence, avoiding testing errors caused by incorrect wire sequences. The second wire sequence indicator displays the network cable sequence at the second interface, working in conjunction with the first indicator to ensure consistent wire sequences at both ends, improving testing accuracy. In other words, the multi-functional optical power meter, designed based on the multi-functional optical power meter housing, can simultaneously perform red light, wire crimping, wire pairing, and optical power detection, thus achieving multi-functional testing. Since the remote receiver only needs to perform wire pairing detection, it can be designed in a small size for easy portability.

[0011] Furthermore, the bottom of the outer casing is provided with a storage cavity, and the remote receiver is detachably assembled into the storage cavity.

[0012] By adopting the above solution, the remote receiver can be disassembled and stored in the storage cavity, reducing the inconvenience for users to carry multiple independent devices and making the whole device more compact and lightweight.

[0013] Furthermore, the remote receiver is provided with a limiting block, and the receiving cavity is provided with a snap-fit ​​component and a trigger component. The snap-fit ​​component and the trigger component are fixedly connected. When the remote receiver is located in the assembly cavity, the snap-fit ​​component is located on the side of the limiting block in the direction in which the remote receiver is detached from the outer shell body, so as to restrict the movement of the limiting block in the direction in which the remote receiver is detached from the outer shell body.

[0014] When the trigger is in the non-triggered state, the latching member contacts the limiting block, and the latching member restricts the limiting block from moving in the direction of disengagement from the remote receiver;

[0015] When the trigger is in the triggered state, the latching member disengages from the limiting block, and the latching member releases its restriction on the limiting block.

[0016] By employing the above solution, when the remote receiver is placed inside the storage cavity, the latching device contacts the limiting block, restricting the movement of the limiting block and thus preventing the remote receiver from accidentally falling out. This ensures the safety of the remote receiver during carrying and transportation. Users can easily unlock the latching device and remove the remote receiver simply by pressing the trigger, making the operation simple and quick, and improving the user experience.

[0017] Furthermore, the trigger includes a trigger button and a reset spring. The snap-fit ​​component passes through the housing body and is fixedly connected to the trigger button. The trigger button has a mounting post on the side facing the housing body. The reset spring is sleeved on the mounting post. One end of the reset spring is in contact with the housing body, and the other end is in contact with the trigger button.

[0018] By adopting the above solution, users can easily unlock the connector by simply pressing the trigger button, allowing the remote receiver to be easily removed. This design simplifies the operation process and improves user convenience. The reset spring design ensures that the trigger button automatically resets to its initial state after being pressed. This not only reduces the number of steps required for the user but also improves the reliability and durability of the device.

[0019] Furthermore, the outer casing body is provided with a snap-fit ​​through hole, the trigger button is connected to a snap-fit, the snap-fit ​​passes through the snap-fit ​​through hole, and the end of the snap-fit ​​away from the trigger button has a hook-shaped part. The inner wall of the outer casing body at the snap-fit ​​through hole limits the hook-shaped part, preventing the hook-shaped part from coming out of the outer casing body.

[0020] By adopting the above solution, the design of the hook-shaped part allows the buckle to be firmly fixed in place after passing through the buckle through hole, preventing the buckle from coming out of the housing body, thereby ensuring the stability and reliability of the trigger.

[0021] Furthermore, a first protective sleeve is provided at the red light emitting head, and the first protective sleeve is detachably fitted onto the red light emitting head.

[0022] By adopting the above solution, the first protective cover can effectively prevent physical damage to the red light emitter caused by accidental events such as collisions and drops during transportation, storage and use, thus extending the service life of the red light emitter. The protective cover can prevent dust, moisture and other contaminants from entering the red light emitter, keeping it clean and dry, and ensuring the normal operation of the red light emitter.

[0023] Furthermore, the outer wall of the first protective sleeve is provided with a first connecting line, one end of the first connecting line is fixedly connected to the outer wall of the first protective sleeve, and the other end is provided with a first anti-retraction protrusion. The outer shell body is provided with a first connecting line assembly hole, and the first anti-retraction protrusion is assembled in the first connecting line assembly hole.

[0024] By adopting the above solution, the first connecting line connects the first protective sleeve to the outer shell body, preventing the protective sleeve from being accidentally lost during use or carrying. The cooperation between the first anti-reverse protrusion and the mounting hole of the first connecting line ensures the first connecting line is firmly fixed, preventing the protective sleeve from falling off due to loosening.

[0025] Furthermore, a second protective sleeve is provided at the optical power detection head, and the second protective sleeve is detachably fitted onto the optical power detection head.

[0026] By adopting the above solution, the second protective sleeve can effectively prevent physical damage to the optical power detection head caused by collisions, drops, or other accidents during transportation, storage, and use, thus extending the service life of the optical power detection head. The protective sleeve can prevent dust and moisture from entering the optical power detection head, keeping it clean and dry, and ensuring the normal operation of the optical power detection head.

[0027] Furthermore, the outer wall of the second protective sleeve is provided with a second connecting line, one end of which is fixedly connected to the outer wall of the second protective sleeve, and the other end is provided with a second anti-retraction protrusion. The outer shell body is provided with a second connecting line assembly hole, and the second anti-retraction protrusion is assembled in the second connecting line assembly hole.

[0028] By adopting the above solution, the second connecting line connects the second protective sleeve to the outer shell body, preventing the protective sleeve from being accidentally lost during use or carrying. The cooperation between the second anti-reverse protrusion and the mounting hole of the second connecting line ensures the secure fixation of the second connecting line, preventing the protective sleeve from falling off due to loosening.

[0029] This utility model also includes a multifunctional optical power meter, comprising a circuit board and the aforementioned optical power meter housing, wherein the circuit board is disposed within the housing body.

[0030] In summary, the multifunctional optical power meter housing and optical power meter provided by this utility model have the following technical effects:

[0031] The first interface provides the foundation for wire crimp and pair testing, allowing users to perform multiple testing tasks on the same device, greatly improving its usability. The second interface is designed to complete remote connections during pair testing, facilitating simultaneous testing from different locations and ensuring the accuracy of the network cable connection. The first wire sequence indicator displays the network cable sequence at the first interface, helping users quickly identify and confirm the sequence, avoiding testing errors caused by incorrect wiring. The second wire sequence indicator displays the network cable sequence at the second interface, working in conjunction with the first indicator to ensure consistent wiring at both ends, improving testing accuracy. In short, the multi-functional optical power meter, designed based on a multi-functional optical power meter housing, can simultaneously perform red light, crimp, pair, and optical power testing, thus achieving multi-functional testing. Since the remote receiver only needs to perform pair testing, it can be designed in a small size for easy portability. Attached Figure Description

[0039] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0040] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0043] See Figures 1-6 This utility model discloses a multifunctional optical power meter housing, including a housing body 1 and a remote receiver 2. The housing body 1 is provided with a display screen 11, a red light emitting head 12, an optical power detection head 13, a first line sequence indicator 15, and a first interface 14 for line detection and line pressing detection. The display screen 11 and the first line sequence indicator 15 are both located on one side of the housing body 1, the red light emitting head 12 and the optical power detection head 13 are both located on the top of the housing body 1, and the first interface 14 is located on one side of the housing body 1. The remote receiver 2 is provided with a second line sequence indicator 22 and a second interface 21 for receiving the line detection signal emitted by the first interface 14.

[0044] Specifically, the outer casing 1 is equipped with a display screen 11, a red light emitting head 12, an optical power detection head 13, a first interface 14, and a first wiring sequence indicator 15. The display screen 11 and the first wiring sequence indicator 15 are both located on one side of the outer casing 1, while the red light emitting head 12 and the optical power detection head 13 are both located on the top of the outer casing 1. The red light emitting head 12 emits red light to help users quickly identify the fiber optic path and connection status. By observing the propagation of red light in the fiber optic cable, users can determine whether the fiber optic cable is correctly connected and whether there are any breaks or bends. The optical power detection head 13 is used to measure the optical power level in fiber optic transmission, including absolute optical power and relative optical power. The first interface 14 is located on one side of the outer casing 1 for wire crimp detection and wire alignment detection in conjunction with a remote receiver. The wire crimp detection result can be displayed on the display screen 11, and the wire alignment detection result is displayed through the first wiring sequence indicator 15 and the second wiring sequence indicator 22. The remote receiver 2 only needs to be paired with an optical power meter to complete the pairing operation. Therefore, it is only necessary to set up a second interface 21 corresponding to the first interface 14 and a second wiring indicator 22, thereby enabling the miniaturization design of the remote receiver 2.

[0045] The wire crimping test is used to detect whether the RJ45 connector inserted into the first interface 14 is properly connected to its corresponding cable.

[0046] Alternatively, the first interface 14 and the second interface 21 can be selected to use RJ45 interfaces for network cable testing. Of course, the interface models of the first interface 14 and the second interface 21 can also be selected according to the requirements of other interface models that match the network cable connectors, and no limitation is made here.

[0047] Alternatively, the display screen 11 can be a touch-screen display screen 11, allowing control of various functional modules by clicking on the display screen 11. Of course, the display screen 11 can also be a conventional display screen 11. In the case of using a conventional display screen 11 with only display function, a control button group can be set on one side of the housing body 1, and the various functional modules can be controlled through the control button group.

[0048] It should be noted that the specific testing methods and procedures are already standard testing techniques, so they will not be elaborated here.

[0049] See Figure 1-4 As shown, in some embodiments, the bottom of the outer casing 1 is provided with a storage cavity 16, and the remote receiver 2 is detachably assembled in the storage cavity 16.

[0050] Specifically, the bottom of the outer shell 1 is provided with a storage cavity 16. Based on the structure that enables the miniaturization of the remote receiver 2, the remote receiver 2 can be detachably assembled in the storage cavity 16, reducing the inconvenience for users to carry multiple independent devices and making the entire device more compact and lightweight.

[0051] See Figure 5 and Figure 6 As shown, based on the structure of the storage cavity 16 at the bottom of the outer shell 1, the remote receiver 2 is provided with a limiting block 23. The storage cavity 16 is provided with a snap-fit ​​component 31 and a trigger component. The snap-fit ​​component 31 is fixedly connected to the trigger component. When the remote receiver 2 is located in the assembly cavity, the snap-fit ​​component 31 is located on the side of the limiting block 23 in the direction in which the remote receiver 2 is removed from the outer shell 1, so as to restrict the movement of the limiting block 23 in the direction in which the remote receiver 2 is removed from the outer shell 1.

[0052] When the trigger is in the non-triggered state, the latching member 31 contacts the limiting block 23, and the latching member 31 restricts the limiting block 23 from moving in the direction of disengaging from the remote receiver 2.

[0053] When the trigger is in the triggered state, the latching member 31 disengages from the limiting block 23, and the latching member 31 releases the limiting block 23.

[0054] Specifically, the remote receiver 2 is equipped with a limiting block 23, and the receiving cavity 16 is equipped with a latching member 31 and a trigger member. The latching member 31 and the trigger member are fixedly connected. When the remote receiver 2 is located in the assembly cavity, the latching member 31 is located on the side of the limiting block 23 in the direction of disengagement, thereby restricting the movement of the limiting block 23 toward the direction in which the remote receiver 2 disengages from the outer shell 1, and thus preventing the remote receiver 2 from disengaging from the receiving cavity 16. The direction in which the remote receiver 2 disengages from the outer shell 1 is the direction in which the remote receiver 2 is pulled out from the outer shell 1. When the trigger member is in the untriggered state, the latching member 31 is in contact with the limiting block 23, and the latching member 31 restricts the movement of the limiting block 23 toward the direction in which the remote receiver 2 disengages. When the trigger member is in the triggered state, the latching member 31 disengages from the limiting block 23, and the latching member 31 releases the limiting effect on the limiting block 23. The trigger member can be a button, an electronic telescopic rod, or other triggering device, which is not limited here.

[0055] See Figure 5 and Figure 6 As shown, in this embodiment, the trigger includes a trigger button 321 and a reset spring 322. The snap-fit ​​member 31 passes through the outer shell body 1 and is fixedly connected to the trigger button 321. The trigger button 321 has a mounting post 323 on the side facing the outer shell body 1. The reset spring 322 is sleeved on the mounting post 323. One end of the reset spring 322 is attached to the outer shell body 1, and the other end is attached to the trigger button 321.

[0056] Specifically, the triggering element includes a trigger button 321 and a return spring 322. A latching member 31 passes through the outer casing 1 and is fixedly connected to the trigger button 321. Correspondingly, the latching member 31 is located inside the outer casing 1, while the trigger button 321 is located outside the outer casing 1, thus facilitating user operation. A mounting post 323 is provided on the side of the trigger button 321 facing the outer casing 1. The return spring 322 is sleeved on the mounting post 323. The mounting post 323 facilitates the installation of the return spring 322 and provides a certain guiding effect during the reciprocating motion of the return spring 322. One end of the return spring 322 is in contact with the outer casing 1, and the other end is in contact with the trigger button 321. That is, when the trigger button 321 is pressed, causing the latching member 31 to disengage from the limiting block 23, the return spring 322 is compressed. When the pressure on the trigger button 321 is released, the return spring 322 pushes the trigger button 321 back to its original position under the action of elastic potential energy.

[0057] See Figure 5 and Figure 6As shown, further, in order to prevent the trigger button 321 from detaching from the outer shell 1 under the action of the reset spring 322, the outer shell 1 is provided with a snap-fit ​​through hole 17. The trigger button 321 is connected to a snap-fit ​​324, which passes through the snap-fit ​​through hole 17. The end of the snap-fit ​​324 away from the trigger button 321 has a hook-shaped part 3241. The inner wall of the outer shell 1 at the snap-fit ​​through hole 17 limits the hook-shaped part 3241, preventing the hook-shaped part 3241 from coming out of the outer shell 1.

[0058] See Figures 1-3 As shown, in some embodiments, a first protective sleeve 4 is provided at the red light emitting head 12, and the first protective sleeve 4 is detachably fitted onto the red light emitting head 12.

[0059] Specifically, the first protective cover 4 can effectively prevent physical damage to the red light emitting head 12 caused by accidental events such as collisions and drops during transportation, storage and use, thus extending the service life of the red light emitting head 12. The protective cover can prevent dust, moisture and other substances from entering the red light emitting head 12, keeping it clean and dry, and ensuring the normal operation of the red light emitting head 12.

[0060] See Figures 1-3 As shown, based on the structure of the first protective sleeve 4, the outer wall of the first protective sleeve 4 is provided with a first connecting line 41. One end of the first connecting line 41 is fixedly connected to the outer wall of the first protective sleeve 4, and the other end is provided with a first anti-retraction protrusion 42. The outer shell body 1 is provided with a first connecting line assembly hole 18, and the first anti-retraction protrusion 42 is assembled in the first connecting line assembly hole 18.

[0061] Specifically, the first connecting line 41 connects the first protective sleeve 4 to the outer shell body 1, preventing the protective sleeve from being accidentally lost during use or carrying. The cooperation between the first anti-reverse protrusion 42 and the first connecting line mounting hole 18 ensures that the first connecting line 41 is firmly fixed, preventing the protective sleeve from falling off due to loosening.

[0062] See Figures 1-3 As shown, in some embodiments, a second protective sleeve 5 is provided at the optical power detection head 13, and the second protective sleeve 5 is detachably fitted onto the optical power detection head 13.

[0063] Specifically, the second protective sleeve 5 can effectively prevent physical damage to the optical power detection head 13 caused by accidental events such as collisions and drops during transportation, storage, and use, thus extending the service life of the optical power detection head 13. The protective sleeve can prevent dust, moisture, etc. from entering the optical power detection head 13, keeping it clean and dry, and ensuring the normal operation of the optical power detection head 13.

[0064] See Figures 1-3As shown, based on the structure of the second protective sleeve 5, the outer wall of the second protective sleeve 5 is provided with a second connecting line 51. One end of the second connecting line 51 is fixedly connected to the outer wall of the second protective sleeve 5, and the other end is provided with a second anti-retraction protrusion 52. The outer shell body 1 is provided with a second connecting line assembly hole 19, and the second anti-retraction protrusion 52 is assembled in the second connecting line assembly hole 19.

[0065] Specifically, the second connecting line 51 connects the second protective sleeve 5 to the outer shell body 1, preventing the protective sleeve from being accidentally lost during use or carrying. The cooperation between the second anti-reverse protrusion 52 and the second connecting line mounting hole 19 ensures that the second connecting line 51 is firmly fixed, preventing the protective sleeve from falling off due to loosening.

[0066] See Figure 2 and Figure 3 As shown, in some embodiments, in order to facilitate the use of the multifunctional optical power meter using the housing body 1 in dim environments, an illumination lamp 6 is provided on the top of the housing body 1 so that auxiliary lighting can be provided in dim environments.

[0067] This utility model also includes a multifunctional optical power meter, comprising a circuit board and the aforementioned optical power meter housing, with the circuit board disposed inside the housing body 1.

[0068] Alternatively, the circuit board can be electrically connected to the display screen 11, the red light emitting head 12, the optical power detection head 13, the first interface 14, and the first line sequence indicator 15 for normal operation of the multi-functional optical power meter.

[0069] See Figures 1-3 As shown, in some embodiments, in order to facilitate charging of the multifunctional optical power meter, a charging interface 7 can be provided on the housing body 1 to charge the multifunctional optical power meter.
