[0002] Field covered wire, also known as field covered wire, is primarily used for voice telephone and telegraph communications, typically within a range of 25 kilometers. Its structure consists of several thin copper and steel wires twisted together to form a core, which is then covered with an insulating layer. This design makes the field covered wire lightweight, easy to carry and retract, flexible, and mechanically strong. It is also cold-resistant, heat-resistant, and wear-resistant, making it reusable. Field covered wire has a wide range of applications, including military field communications, mining and blasting, and temporary communications during exploration.

[0003] A cable fault tester or cable detector is a device specifically used to detect fault points in cables (such as power cables, communication cables, etc.), including breakpoints, short circuits, leakage and other problems. When a fault occurs during the use of the double-line, it needs to be detected by a detection device such as a cable fault tester or cable detector. During the detection, the double-line is connected to the detection connector, and the double-line is mainly used under outdoor conditions. In existing detection equipment, the detection connector is often exposed to the outside of the equipment, and dust and other impurities are easily introduced into the detection connector, affecting the accuracy of the detection. At the same time, there is no corresponding protective structure to protect the detection connector. The detection connector is easily damaged by touch, resulting in poor contact and other problems. Based on this, the utility model proposes a double-line fault detection device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5As shown, a device for detecting a fault in a double-wired line according to an embodiment of the present invention may include a detector body 1, a test probe 2, a protective mechanism and a fixing mechanism, wherein the detector body 1 is used for detecting a fault in a double-wired line; a groove 3 is provided on the back of the detector body 1, one end of the groove 3 passes through the top of the detector body 1, the test probe 2 is connected to the inner wall of the groove 3 away from the top of the detector body 1, and the test probe 2 is electrically connected to the detector body 1; the protective mechanism is an L-shaped structure, which is adapted to the groove 3, and the protective mechanism is slidably and rotatably connected to the groove 3, and the protective mechanism is used to cover the groove 3, which is used to protect the test probe 2, and the double-wired line can pass through the protective mechanism and be inserted into the test probe 2 for detection through the detector body 1; the fixing mechanism is installed on the protective mechanism, and when the double-wired line is inserted into the test probe 2, the double-wired line is fixed in the groove 3 by the fixing mechanism.

[0025] In one embodiment of the present invention, Figure 1 As shown, a detection module is provided on the detection body, the test probe 2 is electrically connected to the detection module, and a button 3, a display screen 4 and an indicator light 6 are installed on the front of the detector body 1, and the button 3, the display screen 4 and the indicator light 6 are electrically connected to the detection module respectively.

[0026] In the specific embodiment of the present invention, the detector body 1 is a conventional product. It calculates the fault distance by measuring impedance changes or signal reflections at the fault point, thereby accurately locating the fault point. This is primarily accomplished through the detection module, and the detection principles of the detection module are not described in detail here. During the test, the display screen 4 displays information such as the signal waveform and fault distance in real time. After the test is completed, the fault distance and waveform analysis results provided by the detector body 1 are used to determine the location of the cable breakpoint.

[0027] In one embodiment of the present invention, a connecting belt 7 is installed on the back of the detector body 1. The connecting belt 7 can be made of nylon material, which is convenient for handholding and prevents the detection device from slipping when held in hand.

[0028] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the protective mechanism includes a protective cover 8, wherein the interior of the protective cover 8 is hollow, and its adjacent two side edges are respectively provided with an opening 1 9 and an opening 2 10, and the protective cover 8 is provided with a rotating rod 12 on both sides of one end of the opening 2 10, and the inner walls on both sides of the groove 3 are provided with a slide 13 adapted to the rotating rod 12, and the opening 1 9 of the protective cover 8 is located at the bottom and is slidably and rotatably connected to the slide 13 through the rotating rod 12.

[0029] like Figure 2 As shown, when not in use, the protective cover 8 completely covers the test probe 2 in the groove 3. The inner wall of the protective cover 8 or the groove 3 can be provided with a sealing adjustment to increase the sealing of the connection. By providing the protective cover 8, dust is prevented from entering the test probe 2 and affecting the accuracy of the detection. The fixing mechanism can fix the protective cover 8 to the detector body 1. In the use state, as shown in FIG. Figure 4 As shown, the protective cover 8 can slide outward to expose the test probe 2, and the multi-wire is connected to the test probe 2 through the protective cover 8, and then the multi-wire is squeezed and fixed on the bottom surface of the groove 3 by the fixing mechanism to prevent the multi-wire from shaking during the test, so that the connection between the multi-wire and the test probe 2 is in an unstable state, affecting the progress of the test.

[0030] In one embodiment of the present invention, Figure 5 As shown, opening three 11 is provided at the bottom of both sides of one end of the protective cover 8 close to the opening two 10. When the protective cover 8 moves to the end of the groove 3 away from the test probe 2, it can be rotated. By providing the opening three 11, the lower end of the protective cover 8 is prevented from touching the bottom of the groove 3 during the rotation process.

[0031] In one embodiment of the present invention, Figure 3 As shown, a through hole 14 is formed at one end of the protective cover 8 away from the second opening 10. Multiple sector-shaped segments 15 are mounted within the through hole 14. These segments 15 are made of silicone material. The curved sides of the segments 15 are fixedly connected to the inner wall of the through hole 14. Multiple segments 15 can be joined to form a circular body. During testing, the wire is passed through the through hole 14 and then connected to the test probe 2.

[0032] In one embodiment of the present invention, Figure 5As shown, the fixing mechanism may include a fastening bolt 16 and an extrusion block 17, wherein a screw hole is provided at one end of the long end of the protective cover 8 close to the test probe 2, and the fastening bolt 16 is threadedly connected to the screw hole; the top of the extrusion block 17 is rotatably connected to the fastening bolt 16, and the extrusion block 17 is slidably connected in the protective cover 8. The extrusion block 17 is a rectangular structure, which is adapted to the internal size of the protective cover 8. By rotating the fastening bolt 16, the extrusion block 17 can be driven to slide up and down, thereby achieving extrusion and fixation of the doubled line. The bottom of the extrusion block 17 is fixedly connected to a rubber block 18, which has a certain elasticity. When the doubled line is extruded and fixed, it avoids extrusion and wear of the cable. After the inspection is completed, the protective cover 8 is pushed to align with the groove 3, and then the fastening bolt 16 is rotated so that the rubber pad abuts against the bottom of the groove 3. At this time, the protective cover 8 can no longer slide. It should be noted that after the protective cover 8 is aligned with the groove 3, there is a certain gap between the fastening bolt 16 and the extrusion block 17 and the test probe 2.

[0033] According to the double-wire fault detection device of the embodiment of the present utility model, a corresponding groove 3 is provided on the detector body 1, and the test probe 2 is installed in the groove 3. The test probe 2 is covered in the groove 3 by the provided protective mechanism, which can prevent dust and other impurities from entering the test probe 2 and affecting the accuracy of the detection. In addition, by providing a fixing mechanism, the double wire can be fixed in the groove 3, avoiding the double wire from shaking during detection, thereby improving the stability of the detection.
