Description

Technical Field

[0001] This utility model relates to the technical field of cable fault testers, and in particular to a cable fault tester. Background Technology

[0002] With the rapid development of industries such as power and communications, cables, as the core carriers of energy transmission and signal transmission, are being deployed in increasingly diverse and complex environments, including urban underground pipe networks, mountainous areas, and high-rise buildings. Over long-term use, cables are affected by factors such as aging, external damage, and environmental corrosion, leading to a gradual increase in the failure rate. Timely and accurate fault detection has become a crucial link in ensuring uninterrupted power supply and communication.

[0003] As a core device for quickly locating fault points, cable fault testers are being used more frequently and in more applications. As workers need to carry the equipment in various environments such as outdoor sites, underground wells, and substations, higher demands are being placed on the portability and practicality of the equipment.

[0004] While existing cable fault testers have an outer casing that makes them easy to carry, they do not consider the need for storing connecting cables. Because the casing lacks a cable storage function, the connecting cables are always piled up in a messy state, and the problem of easy knotting occurs repeatedly. This not only increases the workload of the staff, but also restricts the equipment's ability to respond quickly in emergency scenarios. Utility Model Content

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-5 A cable fault tester includes a housing 1, and the housing 1 is provided with a handle 22 for easy carrying. The cable fault tester body 2 is provided inside the housing 1 for detecting cable faults. The housing 1 is provided with a cover 3, and the cover 3 is provided with a wire assembly. The wire assembly includes a fixing frame 10 provided on the inner wall of the cover 3, a fixing shaft 11 fixedly connected to the fixing frame 10, a wire reel 9 provided on the fixing shaft 11, and a connecting wire 4 provided on the wire reel 9.

[0026] Furthermore, an outer bushing 18 is rotatably connected to the outer side of the fixed shaft 11, and a rotating frame 14 is provided on the outer bushing 18. A second groove 15 is provided on the rotating frame 14, located on the outer side of the connecting line 4.

[0027] The cover 3 is also equipped with a drive assembly for driving the outer bushing 18 to rotate.

[0028] Specifically, the outer bushing 18 is driven to rotate around the fixed shaft 11 by the drive component. The outer bushing 18 drives the rotating frame 14 to rotate, which in turn drives the connecting wire 4 located inside the second wire trough 15 to rotate and unfold from the wire reel 9. Alternatively, the drive component can drive the rotating frame 14 to rotate in the opposite direction, causing the connecting wire 4 to be wound back onto the wire reel 9. This facilitates the collection and organization of the connecting wire 4 used to connect the main body 2 of the cable fault tester and the cable to be tested. On the one hand, it avoids the problem of the connecting wire 4 easily getting tangled due to being messy. On the other hand, it can automatically unfold and rewind the connecting wire 4 onto the wire reel 9, solving the problem of connecting wires easily getting tangled due to messy stacking in traditional cable management methods, and effectively avoiding a lot of time wasted on organizing cables.

[0029] Furthermore, a first groove 12 is provided on the fixed shaft 11 to facilitate the connection wire 4 to pass through the first groove 12 and connect to the main body 2 of the cable fault tester. A plastic wire clip 6 is also provided on the inner wall of the box cover 3. It should be noted that the plastic wire clip 6 is made of plastic and has a certain degree of elasticity and toughness. It can hold the connection wire 4 in place, so that during the carrying of the box cover 1, the connection wire 4 inside the box cover 1 is not excessively connected. This can prevent the plug 5 on the connection wire 4 from running around and causing it to bump into the main body 2 of the cable fault tester inside and cause damage.

[0030] Furthermore, a protective shell 19 is provided on the outer wall of the box cover 3, located on the outside of the coil 9, and a mounting plate 20 is provided on the protective shell 19, and bolts 21 are provided on the mounting plate 20;

[0031] The cover 3 is provided with a threaded groove that matches the bolt 21.

[0032] Specifically, without using the main body 2 of the cable fault tester, the protective shell 19 can be placed over the outside of the cable reel 9 and the bolt 21 can be screwed into the threaded groove to isolate the connecting wire 4 on the cable reel 9, thus preventing dust from accumulating on the connecting wire 4.

[0033] Furthermore, the drive assembly includes a micro motor 16 disposed on the inner wall of the cover 3. The output end of the micro motor 16 is connected to the outer bushing 18 via a reduction chain assembly 17. It should be noted that the reduction chain assembly 17 consists of two sprockets and a chain sleeved on the two sprockets. This is an existing product, as shown in the attached drawings of the specification, and will not be described in detail. Specifically, the micro motor 16 drives the outer bushing 18 to rotate through the reduction chain assembly 17, and the outer bushing 18 then drives the rotating frame 14 to rotate.

[0034] Furthermore, a fixing shell 7 is provided on the inner side of the cover 3, located on the outer side of the drive assembly, and a heat dissipation channel 8 is provided on the fixing shell 7, which can provide a heat dissipation channel 8 for the micro motor 16.

[0035] Furthermore, the connecting line 4 is arranged to pass through the fixed shell 7.

[0036] Furthermore, a plug 5 is provided on one end of the connecting line 4 for connecting to the interface on the main body 2 of the cable fault tester, and a connecting clip 13 is provided on the other end of the connecting line 4 to clamp the connector of the cable to be tested, thereby facilitating the detection of faulty cables by the main body 2 of the cable fault tester.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
