[0021] 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.

[0022] Please see Figure 1-5 This utility model provides the following technical solution: a fault detection device for communication transmission, comprising: a detector body 1, a protective shell 2 sleeved on the surface of the detector body 1, a first bolt 3 horizontally penetrating the open end surface of the protective shell 2, the side wall of the first bolt 3 being threadedly connected to the surface of the detector body 1, a rubber baffle 4 bonded to the top surface of the detector body 1, the surface of the rubber baffle 4 being fitted and connected to the open end of a movable plate 5, the movable plate 5 being slidably connected to the side wall of the protective shell 2, a limiting rod 6 longitudinally penetrating the top of the protective shell 2, the bottom of the limiting rod 6 being engaged with a slot 7, the slot 7 being opened in the movable plate 5. At the top of the horizontal end, a mounting groove 8 is opened on one side of the longitudinal end of the protective shell 2. A sliding door 9 is fitted onto the surface of the mounting groove 8. A second bolt 10 is connected through the protrusion surface on one side of the sliding door 9. The side wall of the second bolt 10 is threaded to the protective shell 2. A connecting ear 11 is provided on the protrusion end surface of the sliding door 9. In this design, the detector body 1 constitutes the main body of the communication cable fault comprehensive tester. A large number of related components are set in the main body of the communication cable fault comprehensive tester. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] The main model of the communication cable fault comprehensive tester in this solution is: GWCT-500;

[0024] In use: The communication cable fault comprehensive tester locates faults by sending pulse signals to the cable and analyzing the signal propagation within the cable. When the pulse encounters a change in cable impedance (such as at the fault point), part of the signal is reflected back to the tester. By measuring the time delay and intensity of the reflected signal, the distance between the fault point and the test point can be calculated. The GWCT-500 tester utilizes this principle to accurately detect faults in communication cables, such as broken wires, mixed wires, and severe insulation defects.

[0025] Preferably, the detector body 1, the protective shell 2, and the first bolt 3 form a threaded connection structure.

[0026] In practical use, when using the detector body 1 to detect communication transmission faults, the protective shell 2 is fixed to the surface of the detector body 1 using the first bolt 3.

[0027] Preferably, a rectangular groove is provided on one side of the movable plate 5, and the shape and size of the groove are adapted to the horizontal end of the rubber baffle 4. The rubber baffle 4 is an "L" shaped integrated structure.

[0028] In practical use, the movable plate 5 slides on the protective shell 2, and then the limiting rod 6 passes through the protective shell 2 and is locked in the slot 7 opened on the surface of the movable plate 5, thereby fixing the position of the movable plate 5 on the protective shell 2.

[0029] Preferably, the protective shell 2 has a rectangular through groove on its side wall, and the shape and size of the through groove are adapted to the movable plate 5.

[0030] In practical use, the through groove on one side of the protective shell 2 allows the movable plate 5 to slide on the protective shell 2 to shield the detector body 1.

[0031] Preferably, the protective shell 2, the movable plate 5, and the limiting rod 6 form a snap-fit ​​connection structure.

[0032] In practical use, the movable plate 5 slides on the protective shell 2, and then the limiting rod 6 passes through the protective shell 2 and is locked in the slot 7 opened on the surface of the movable plate 5, thereby fixing the position of the movable plate 5 on the protective shell 2.

[0033] Preferably, two cylindrical protrusions are symmetrically distributed on the surface of the sliding door 9, and the shape and size of the protrusions are adapted to the rotating groove provided in the mounting groove 8. The protective shell 2, the sliding door 9 and the second bolt 10 form a threaded connection structure.

[0034] In actual use, unscrew the second bolt 10 fixed between the protective shell 2 and the movable door 9, and then grasp the connecting ear 11 to pull the movable door 9 outward to rotate it, thereby exposing the data cable slot provided on the side wall of the detector body 1 that was previously covered.

[0035] Working principle: When using the detector body 1 to detect communication transmission faults, the protective shell 2 is fixed to the surface of the detector body 1 using the first bolt 3. Then, the movable plate 5 slides on the protective shell 2. The limiting rod 6 passes through the protective shell 2 and engages with the slot 7 on the surface of the movable plate 5, thus fixing the position of the movable plate 5 on the protective shell 2. The cooperation between the protective shell 2 and the movable plate 5 protects the button area and display screen on the surface of the detector body 1, preventing the user from accidentally touching the buttons and affecting the detection results of the detector body 1. When using, first unscrew the second bolt 10 fixed between the protective shell 2 and the movable door 9 to grip the device. Pulling the connecting ear 11 outwards to move the sliding door 9 rotates it, thereby revealing the data cable slot on the side wall of the detector body 1, which was previously covered. This allows the user to connect the data cable for testing. At this time, the button area on the surface of the detector body 1 can be operated to start the test. After the operation is completed, the above actions can be repeated to protect and cover the button area of ​​the detector body 1. Meanwhile, the observation window on the surface of the moving plate 5 allows the user to observe the display content on the screen of the detector body 1. In addition, when operation is needed again, the limiting rod 6 that is engaged with the protective shell 2 and the moving plate 5 can be pulled out to move the moving plate 5 to one side to reveal the button area of ​​the detector body 1, which was previously covered, so that it can be operated.

[0036] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
