Description

Technical Field

[0001] This utility model belongs to the field of optical fiber testing technology, specifically relating to an optical fiber patch cord testing device. Background Technology

[0002] Fiber optic patch cord testing is a crucial step in ensuring the performance and reliability of fiber optic communication systems. It is used to check whether the optical performance of fiber optic patch cords meets the requirements, ensuring that the loss, attenuation, and other indicators of signals transmitted through the fiber are within the specified range to guarantee communication quality. It also detects whether there is physical damage to the fiber optic patch cords, such as fiber breaks, end-face contamination, scratches, etc., to avoid signal transmission interruptions or quality degradation caused by these problems.

[0003] Fiber optic patch cord test pens, also known as fiber optic red light pens, are commonly used devices for testing fiber optic patch cords. They are used to detect fiber optic connectivity, locate fiber optic faults, and identify fiber optic lines. Currently, fiber optic patch cord test pens are equipped with components to protect the test head.

[0004] For example, in the prior art, Chinese utility model patent with authorization announcement number CN218239272U discloses a "fiber optic patch cord test pen", which includes a test pen body, a protective tube sleeved on the outer side of the test head of the test pen body, a movable groove opened on the inner wall of the protective tube, a spring longitudinally installed on the side wall of the movable groove, a limiting ring fixedly installed on the side wall of the test pen body that fits against the movable groove and the side wall of the spring, and a fixing ring fixedly installed on the lower opening of the protective tube that fits against the limiting ring.

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.

[0044] It should be noted that the internal structure and testing principle of the fiber optic patch cord tester are existing technologies that have been fully disclosed, and will not be elaborated further in the following text. For details, please refer to the existing technology of fiber optic patch cord testers.

[0045] Please see Figures 1-5 The present invention provides the following technical solution: a fiber optic patch cord testing device, comprising a red light pen body 1, a test head 2 provided at the front end of the red light pen body 1, a switch button 3 embedded in the red light pen body 1, and further comprising: an anti-accidental touch mechanism 8 and an elastic reset mechanism 9, wherein the anti-accidental touch mechanism 8 comprises: a movable sleeve 81 and an anti-accidental touch cover 82; wherein the elastic reset mechanism 9 comprises: a limit ring 91 and a reset spring 92.

[0046] Furthermore, by Figure 1 , Figures 3-5As shown, in this embodiment, the movable sleeve 81 is fitted onto the red light pen body 1, and a guide hole 811 for the switch button 3 to pass through is machined on the movable sleeve 81. The anti-accidental touch cover 82 is fixed to the outer wall of the movable sleeve 81. When the movable sleeve 81 moves to the maximum position towards the front end of the red light pen body 1, the anti-accidental touch cover 82 is located directly above the switch button 3. The limiting ring 91 is fixed to the outer wall of the red light pen body 1. The reset spring 92 is fitted onto the red light pen body 1 and is located between the movable sleeve 81 and the limiting ring 91. With the above scheme, in use, the fiber optic connector is inserted into the test head 2, and then the movable sleeve 81 is pulled back. At this time, the movable sleeve 81, in conjunction with the limiting ring 91, causes the reset spring 92 to retract and drives the anti-accidental touch cover 82 to move. When the anti-accidental touch cover 82 deviates from the switch button 3, pressing the switch button 3 will start the red light pen body 1, and the test head 2 will generate red light to test the fiber optic cable. Pressing the switch button 3 will release the movable sleeve. At this time, the return spring 92 releases its elastic force to reset the movable sleeve 81, which covers the switch button 3 to prevent the red light pen body 1 from closing due to accidental touch. After the test is completed, pull the movable sleeve 81 back again. When the anti-accidental touch cover 82 is away from the switch button 3, press the switch button 3 again to close the red light pen body 1. After the red light pen body 1 is closed, the movable sleeve 81 can be released. At this time, the return spring 92 releases its elastic force to reset the movable sleeve 81, which covers the switch button 3 to prevent the red light pen body 1 from accidentally opening due to accidental touch. This utility model, through the cooperation of the anti-accidental touch mechanism 8 and the elastic reset mechanism 9, can automatically cover the switch button 3 with the anti-accidental touch cover 82, avoiding accidental touch of the switch button 3 during carrying, preventing the red light pen body 1 from accidentally opening due to accidental touch, and also preventing the red light pen body 1 from accidentally closing due to accidental touch during the test.

[0047] Preferably, by Figure 1 , Figures 3-5 As shown, this embodiment also includes: an isolation sleeve 93, a limiting ring 91 fixed to the tail end of the movable sleeve 81, and the limiting ring 91 and the return spring 92 both located inside the isolation sleeve 93. With the above solution, during use, the isolation sleeve 93 is used to isolate the limiting ring 91 and the return spring 92, making the operation safer and preventing the return spring 92 from accidentally pinching the user's fingers.

[0048] Preferably, by Figure 1 , Figure 3 and Figure 4As shown, this embodiment also includes a guide screw 83, which is installed on the red light pen body 1 by thread engagement. A second guide sliding hole 812 is machined on the movable sleeve 81 for the guide screw 83 to pass through. With the above solution, during use, the guide screw 83 cooperates with the second guide sliding hole 812 to further guide the movable sleeve 81 and limit the movement range of the movable sleeve 81.

[0049] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes: a protective head 4, side wings 41, clamping blocks 42, mounting rod 43, and a telescopic spring 7. The protective head 4 is installed on the front end of the red light pen body 1 by a threaded engagement. The test head 2 extends out of the protective head 4. The two side wings 41 are symmetrically fixed to the end face of the protective head 4. The two clamping blocks 42 are symmetrically distributed, and each clamping block 42 has an arc-shaped clamping groove 421 for clamping the optical fiber. The mounting rod 43 is fixed to the outer wall of the clamping block 42 and passes through the side wings 41. The telescopic spring 7 is sleeved on the mounting rod 43 and is located between the clamping block 42 and the side wings 41. With the above scheme, when the optical fiber connector is inserted into the test head 2, the optical fiber connector passes through the inner space of the two clamping blocks 42. Under the elastic force of the telescopic spring 7, the two clamping blocks 42 clamp the optical fiber connector inward, improving the stability of the insertion of the optical fiber connector into the test head 2 and preventing the optical fiber connector from accidentally falling off.

[0050] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a limiting disk 431. Two symmetrically distributed mounting rods 43 are fixed on the clamping block 42. The limiting disk 431 is fixed to the end of the mounting rod 43 away from the clamping block 42.

[0055] The working principle and usage process of this utility model: When using the fiber optic patch cord testing device of this utility model, the fiber optic connector is inserted into the test head 2, and then the movable sleeve 81 is pulled back. At this time, the movable sleeve 81, together with the limit ring 91, causes the reset spring 92 to retract and drives the anti-accidental contact cover 82 to move. When the anti-accidental contact cover 82 deviates from the switch button 3, pressing the switch button 3 will start the red light pen body 1, and the test head 2 will generate red light to test the fiber optic cable.

[0056] After pressing the switch button 3, the movable sleeve 81 will be released. At this time, the reset spring 92 releases its elasticity to reset the movable sleeve 81. The movable sleeve 81 covers the switch button 3 to prevent the red light pen body 1 from being turned off due to accidental touch.

[0057] After the test is completed, pull the movable sleeve 81 back again. When the anti-accidental touch cover 82 deviates from the switch button 3, press the switch button 3 again to close the red light pen body 1. After the red light pen body 1 is closed, the movable sleeve 81 can be released. At this time, the reset spring 92 releases its elasticity to reset the movable sleeve 81. The movable sleeve 81 covers the switch button 3 to prevent the red light pen body 1 from being accidentally turned on due to accidental touch.

[0058] This utility model, through the cooperation of the anti-accidental touch mechanism 8 and the elastic reset mechanism 9, can automatically cover the switch button 3 with the anti-accidental touch cover 82, thereby preventing accidental touch of the switch button 3 during carrying, preventing the red light pen body 1 from being accidentally opened due to accidental touch, and also preventing the red light pen body 1 from being accidentally closed due to accidental touch during the detection process.

[0059] In another aspect of this utility model, when the fiber optic connector is inserted into the test head 2, the fiber optic connector passes through the inner space of the two clamping blocks 42. Under the elastic force of the telescopic spring 7, the two clamping blocks 42 clamp the fiber optic connector inward, thereby improving the stability of the insertion of the fiber optic connector into the test head 2 and preventing the fiber optic connector from accidentally falling off.

[0060] In addition, when the red light pen body 1 is not in use, the protective cover 5 is installed on the external threaded sleeve 44 by screwing it on to provide safety protection for the test head 2.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
