Detailed Implementation

[0015] 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.

[0016] like Figures 1 to 6 As shown, this utility model provides an electrical fault detection device, including a fixed base 1 and a cable end 4. The top of the fixed base 1 is provided with a detection component 3 for detecting the cable end 4. The detection component 3 is composed of a transmission component 31, a limiting component 32 and a sliding component 33. In this embodiment, the detection component 3 works in concert with the transmission component 31, the limiting component 32 and the sliding component 33 to clamp the cable end 4 and the wire harness connected to the cable end 4, so as to prevent the electrical equipment from malfunctioning due to the cable end 4 coming loose. The transmission component 31 is located inside the square groove with the opening facing downward in the fixed base 1, and is used to push the limiting component 32 to slide at the top of the fixed base 1 to limit the cable end 4. The sliding component 33 is provided with a device for clamping the cable end 4. The sliding component 33 is spaced from the top of the fixed base 1. The other end of the sliding component 33 is fixedly connected to the storage box 2, and the bottom end of the storage box 2 is fixedly connected to the top of the fixed base 1. In this embodiment, the throttle 311 drives the central gear 312 to rotate, and the central gear 312 drives the horizontal toothed plate 313, which is fixedly connected to the top, to slide in the groove at the top of the fixed base 1. During the sliding process, the fixed plate 321 is driven to move closer to the storage box 2.

[0017] In this embodiment, a transverse sliding groove is provided at the top of the fixed base 1. A fixed plate 321 is slidably connected inside the transverse sliding groove of the fixed base 1. A symmetrical limiting block 323 is fixedly connected at the top of the fixed plate 321. A sliding seat 322 is slidably connected between the two sets of limiting blocks 323. The auxiliary sliding seat 322 slides between the two sets of limiting blocks 323 to prevent it from falling off. The sliding seat 322 slides on the surface of the fixed plate 321.

[0018] In this embodiment, the U-shaped seat 331, located away from the transmission component 31, is fixedly connected to the storage box 2. The U-shaped seat 331 has a threaded rod 333 inside, and the threaded rod 333 passes through the U-shaped seat 332 on the outside. The U-shaped seat 332 slides back and forth in the position of the U-shaped seat 331. When it is necessary to clamp the end of the cable end 4, the threaded rod 333 rotates, causing the U-shaped seat 332 to slide towards the U-shaped seat 331. The U-shaped seat 331 and the U-shaped seat 332 form a cross structure. The two overlapping positions are used to clamp the loose end of the cable end 4. In this embodiment, the ends of the threaded rod 333 and the U-shaped seat 332 are set in an inclined position, and the end of the cable end 4 is located between the two sets of inclined ends.

[0019] In this embodiment, a magnifying glass 5 is rotatably connected to the top of the storage box 2. When observing the surface of the cable end 4, commonly used replacement parts can be placed inside the storage box 2. The magnifying glass 5 can magnify the location of small cracks, making it easier for maintenance personnel to check.

[0020] In this embodiment, U-shaped base 1 331 and U-shaped base 2 332 are arranged in a U-shaped structure.

[0021] The fixed base 1 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0022] Working principle: When equipment malfunctions due to open circuits or poor contact in the electrical circuit, it is necessary to determine whether the electrical fault is caused by a loose cable end 4 through testing. By shaking the position of the cable end 4 and the connector, if there is obvious shaking between the cable end 4 and the connector, it indicates that the cable end 4 is loose. The cable end 4 needs to be removed, clamped, and then the cable end 4 should be inserted tightly into the connector. The specific steps are as follows: Place the removed cable end 4 between U-shaped seat 331 and U-shaped seat 332. Based on the shape of the cable end 4, tighten the threaded rod 333. During tightening, the threaded rod 333 will move U-shaped seat 332 closer to U-shaped seat 331. After the two sets of inclined positions clamp the cable end 4, stop rotating the threaded rod 333. The wire harness connected to the cable end 4 is placed between the sliding seat 322 and the fixed plate 321. When the wire harness connected to the cable end 4 is short, the handle 311 is turned, which drives the central gear 312 to rotate. During the rotation, the fixed plate 321 connected to the horizontal toothed plate 313 is driven to slide towards the end of the cable end 4, and the wire harness connected to the cable end 4 is placed between the sliding seat 322 and the fixed plate 321 for clamping inside the wire harness connected to the cable end 4. This prevents the internal connection from breaking due to aging of the wire harness surface. The protrusion 324 is rotated, and the protruding position of the protrusion 324 pushes the sliding seat 322 towards the position of the limiting block 323. During the pushing process, the wire harness connected to the surface of the cable end 4 is clamped inside. After clamping for a period of time, the rotation of the protrusion 324 is stopped, and the handle 311 is turned counterclockwise to control the fixed plate 321 to return to the original direction of sliding. During the sliding process, the step of rotating the protrusion 324 is repeated to clamp. After clamping the cable end 4, remove the cable end 4 from the inside of the sliding component 33 and reinstall it in its original position. Use the magnifying glass 5 to magnify and inspect the surface of the cable end 4.
