Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage wire harness testing equipment, specifically a high-voltage wire harness performance testing device. Background Technology

[0002] High-voltage cable harnesses are cable assemblies used to transmit high-voltage electrical energy, typically found in applications such as new energy vehicles, power systems, and industrial equipment where high-voltage transmission is required. They consist of multiple high-voltage conductors, insulation layers, shielding layers, and sheaths, and are characterized by high voltage withstand capability, excellent insulation performance, and high mechanical strength.

[0003] Currently, the high-voltage wire harness testing slots cannot be moved flexibly. Testing personnel need to frequently move the wire harness or testing equipment to adapt to the position of the testing slot, which greatly increases the preparation time and operation steps. For high-voltage wire harnesses that need to be tested in batches, the inconvenience of moving the testing slots can lead to the inability to carry out the testing process continuously. After each test, the position of the testing slot or wire harness needs to be readjusted, which cannot achieve efficient assembly line operation and reduces the overall testing efficiency. Furthermore, it is currently impossible to perform efficient damage detection on high-voltage wire harnesses. Damage to high-voltage wire harnesses may cause abnormal current flow, which may damage the connected high-voltage equipment, increasing maintenance costs and equipment downtime. Therefore, a high-voltage wire harness performance testing device is needed to improve the above problems. Utility Model Content

[0004] To address the current limitations of flexible movement of high-voltage wire harness testing slots, which necessitates frequent repositioning of the wire harness or testing equipment to accommodate the slot position, significantly increasing preparation time and operational steps, and disrupting the continuous testing process for high-voltage wire harnesses requiring batch testing, the inconvenience of slot repositioning necessitates readjustment of the slot or wire harness position after each test. This hinders efficient assembly line operations, reduces overall testing efficiency, and prevents efficient damage detection of high-voltage wire harnesses. Damage to high-voltage wire harnesses can lead to abnormal current flow, potentially damaging connected high-voltage equipment and increasing maintenance costs and equipment downtime. The purpose of this invention is to provide a high-voltage wire harness performance testing device to solve the problems described in the background section.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0026] A high-voltage wire harness performance testing device includes a main body 1, and a movable testing component 2 and a wire harness damage detection component 3 are fixedly connected inside the main body 1.

[0027] In this embodiment, as Figure 1 , Figure 2and Figure 3 As shown, the mobile detection assembly 2 includes a detection platform 201, a support plate 204 fixedly connected to the bottom of the detection platform 201, a telescopic cylinder 205 mounted on the side of the support plate 204, a connecting block 206 fixedly connected to the output end of the telescopic cylinder 205, and a detection slot seat 207 mounted on the top of the connecting block 206. The wire harness damage detection assembly 3 includes a base plate 301, a telescopic rod 302 mounted on the top of the base plate 301, a top plate 303 fixedly connected to the output end of the telescopic rod 302, and a laser emitter 304 and an infrared sensor mounted on the top of the top plate 303. The thermal imager 305 utilizes the telescopic cylinder 205 to extend and retract, allowing the connecting block 206 to automatically slide the detection slot seat 207 within the slide groove 202. This enables flexible adjustments based on the length, specifications, and detection position of the wire harness, eliminating the need for frequent movement of the wire harness or detection equipment. This significantly reduces preparation and adjustment time before detection, improving overall detection efficiency. Moving the detection slot seat 207 ensures that the connection position between the wire harness and the detection slot seat 207 is consistent during each detection, avoiding repeated detections due to positional deviations, thereby saving time and resources.

[0028] The bottom of the testing platform 201 is fixedly connected to a support column 203, and the telescopic cylinder 205 is fixedly connected to the testing platform 201. The testing platform 201 has two sliding grooves 202. The testing slot seat 207 slides inside the sliding groove 202. The telescopic cylinder 205, the connecting block 206, and the testing slot seat 207 are provided in two ways. The laser emitter 304 irradiates the wire bundle and the infrared thermal imager 305 captures the infrared radiation on the surface of the wire bundle. This testing method does not require contact with the wire bundle being tested, which not only avoids physical damage to the wire bundle, but also completes large-area or long-distance testing in a short time, improving testing efficiency. At the same time, it can also detect tiny defects and has high sensitivity and resolution.

[0029] In this embodiment, as Figure 1 and Figure 4As shown, the main body 1 includes a cabinet 101. An installation plate 104 is fixedly connected inside the cabinet 101. A data display screen 105 is fixedly connected to the side of the installation plate 104. A cabinet door 102 is provided on the side of the cabinet 101. A handle 103 is fixedly connected to the side of the cabinet door 102. A controller 106 is fixedly connected to the side of the cabinet 101. An operation screen 107 is fixedly connected to the side of the controller 106. Operation buttons 108 and start / stop buttons 109 are provided on the side of the controller 106. A support rod 110 is fixedly connected to the bottom of the cabinet 101. A foot 111 is fixedly connected to the bottom of the support rod 110. A grating 112 is installed inside the cabinet 101. The data display screen 105 can intuitively present complex data and information in the form of graphics, charts, and text, enabling users to quickly understand and analyze the data content. Many data display screens 105 support real-time updates, instantly displaying the latest data and status information to help users make timely decisions.

[0030] The working process of this utility model is as follows: When the high-voltage wire harness performance testing device designed in this scheme is in operation, the two ends of the wire harness to be tested are inserted into the testing slot seat 207 respectively. The extension and retraction of the telescopic cylinder 205 allows the connecting block 206 to drive the testing slot seat 207 to slide automatically inside the slide groove 202. This allows for flexible adjustment according to the length, specifications, and testing position of the wire harness. When performing damage testing on the wire harness, the parameters of the laser emitter 304 and the infrared thermal imager 305 can be adjusted according to the specifications of the wire harness and the testing requirements. 4. Irradiate the wire harness using point excitation, line excitation, or surface excitation methods. The infrared thermal imager 305 captures the temperature field or interference pattern on the surface of the wire harness. The processor inside the controller 106 analyzes the collected data and extracts defect information, thus completing the non-destructive testing of the wire harness. During operation, when personnel or objects enter the detection area of ​​the grating 112, the grating 112 will immediately detect the obstruction signal and trigger a safety output signal, causing the equipment to stop operating or enter a safe state, thereby preventing personnel from entering the dangerous area and avoiding accidents.
