Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, specifically a high-voltage resistant automatic marking wire harness testing device. Background Technology

[0002] High-voltage integrated wiring harnesses are core connection components in new energy vehicles, energy storage systems, and high-voltage power supply equipment. They primarily handle the transmission of high-voltage electrical energy and the interaction of related control signals, directly impacting the operational safety and stability of the entire system. Because these harnesses operate in harsh environments of high voltage and high current for extended periods, their insulation performance and withstand voltage are highly susceptible to degradation due to manufacturing defects, material aging, and assembly damage. Insulation damage or insufficient withstand voltage can lead not only to equipment shutdown and malfunction but also to serious safety accidents such as leakage, short circuits, and even fires. Therefore, conducting withstand voltage tests and insulation performance inspections during the production process of high-voltage integrated wiring harnesses is a crucial step in ensuring product quality and mitigating safety risks.

[0003] Currently, the production process of high-voltage integrated wire harnesses only completes the withstand voltage and insulation tests of the wire harnesses, but lacks an effective marking method that is directly related to the test results. Manual marking is generally used. However, this method is not only greatly affected by subjective factors such as operator fatigue and sense of responsibility, but also has the risk of failure such as missing marking, incorrect marking, and inconsistent marking positions. Furthermore, it is difficult to adapt to the efficiency requirements of mass production, resulting in slow production pace and poor consistency of product marking standards.

[0004] To address the aforementioned issues, we provide a high-voltage resistant automatic marking wire harness inspection device to solve the problems mentioned above. Utility Model Content

[0008] As a further embodiment of this utility model: the locking assembly includes a strip-shaped through hole, which is opened on both sides of the U-shaped mold base and the pressure cover. The base is provided with threaded holes at the position below the strip-shaped through hole. Long screws are inserted into the strip-shaped through holes on the pressure cover and the U-shaped mold base, and the long screws are threadedly connected to the threaded holes.

[0009] As a further improvement of this utility model: the tail of the connecting socket is provided with a limiting groove, the limiting groove is distributed on one side and the upper and lower end faces of the connecting socket, and the U-shaped mold base is provided with a limiting protrusion that cooperates with the limiting groove on one side and the bottom.

[0010] As a further improvement of this utility model, a wire harness through groove is provided at one end of the U-shaped mold base near the fixed bracket.

[0011] As a further embodiment of this invention: the test component includes a testing device and a wire, and the testing device is electrically connected to a connection socket via the wire.

[0012] As a further embodiment of this utility model: the marking component includes an L-shaped plate, which is fixedly connected to the position of the automatic control unit's operating end. A mounting cylinder is fixedly connected to the L-shaped plate, and a marking pen is inserted inside the mounting cylinder. A locking screw for fixing the marking pen is threaded onto the mounting cylinder.

[0013] As a further improvement of this utility model, a marking slot is provided at the upper end of the connecting socket opposite to the marking pen.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a testing component to inspect high-voltage integrated wire harnesses. The testing equipment outputs a qualified signal directly to the automatic control unit, which then marks the qualified high-voltage integrated wire harnesses using a marking component. This replaces the traditional manual marking method, ensuring precise marking at designated locations. This effectively avoids the problems of missed or incorrect marking caused by subjective factors in manual operation. Simultaneously, it ensures that the marking positions and styles of all qualified products are uniform and standardized, resolving industry issues caused by the inability to trace whether products have been inspected or the high failure rate due to manual marking. Furthermore, it improves the efficiency and consistency of mass production. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-2 In this embodiment of the present invention, a high-voltage resistant automatic marking wire harness testing device includes a base 3, a connection socket 7 is provided on one side of the upper end face of the base 3, and a fixing component is provided on the testing device 1 for fixing the connection socket 7; the fixing component is used to fix the connection socket 7 to ensure the stability of the connection socket 7 when inserting or removing the high-voltage integrated wire harness.

[0021] Please see Figures 2-3The fixing assembly includes a U-shaped mold base 9, which is located in the middle of one side of the base 3. The connecting socket 7 is placed inside the U-shaped mold base 9. A pressure cover 6 is provided at the upper end of the U-shaped mold base 9, and a locking assembly for locking the pressure cover 6 is provided on the pressure cover 6. The locking assembly includes a strip-shaped through hole 16, which is opened on both sides of the U-shaped mold base 9 and the pressure cover 6. Threaded holes 11 are opened on both sides of the base 3 below the strip-shaped through holes 16. Long threads pass through the strip-shaped through holes 16 on the pressure cover 6 and the U-shaped mold base 9. The long screw 15 is threadedly connected to the threaded hole 11. When installing the connecting socket 7, the connecting socket 7 is placed inside the U-shaped mold base 9, and then the pressure cover 6 at the upper end of the U-shaped mold base 9 is covered. Then, the long screw 15 is inserted into the corresponding strip-shaped through holes 16 on both sides of the U-shaped mold base 9 and the pressure cover 6, so that the lower end of the long screw 15 is aligned with the threaded hole 11 at the corresponding position on the base 3. Finally, the long screw 15 is tightened into the threaded hole 11. The locking force generated by the threaded engagement is used to firmly fix the pressure cover 6 and the U-shaped mold base 9, and to stably fix the connecting socket 7.

[0022] Please see Figure 3 The connector 7 has a limiting groove 18 at its tail end, which is distributed on one side and the upper and lower end faces of the connector 7. The U-shaped mold base 9 has a limiting protrusion 17 on one side and the bottom that mates with the limiting groove 18. The U-shaped mold base 9 has a wire harness through slot 14 at the end near the fixed bracket 10. The limiting groove 18 on the side and lower end face of the connector 7 can fit into the limiting protrusion 17 on the inner side of the U-shaped mold base 9. The limiting protrusion 17 achieves initial positioning when the connector 7 is placed into the U-shaped mold base 9 to avoid placement deviation. The two work together to form a positioning structure to prevent the connector 7 from shifting or shaking during subsequent locking and use, thereby improving the fixation stability.

[0023] Please see Figure 1 The connection socket 7 is connected to a test component for testing the product. The test component includes a testing device 1 and a wire 2. The testing device 1 is electrically connected to the connection socket 7 via the wire 2. The connection socket 7 serves as the connection carrier between the wire harness to be tested and the test component. It and the testing device 1 form a complete electrical path through the wire 2. When the wire harness to be tested is connected to the connection socket 7, the testing device 1 can transmit a preset test electrical signal to the wire harness through the wire 2, and at the same time receive the wire harness electrical performance data fed back by the connection socket 7. Based on these data, the key indicators such as the product's withstand voltage and insulation are tested and judged.

[0024] Please see Figures 2-3A fixed bracket 10 is fixedly connected to the other side of the upper surface of the base 3. An automatic control unit 4 is installed on the fixed bracket 10. The automatic control unit 4 is an electric lifting module. The actuating end of the automatic control unit 4 is provided with a marking component for marking the product. The marking component includes an L-shaped plate 8, which is fixedly connected to the actuating end of the automatic control unit 4. A mounting cylinder 13 is fixedly connected to the L-shaped plate 8. A marking pen 5 is inserted into the mounting cylinder 13. A locking screw 12 for fixing the marking pen 5 is threaded onto the mounting cylinder 13. The upper end of the connecting socket 7 is connected to the marking... The marker pen 5 has a marking slot 19 at the opposite position; the marking assembly is fixed to the actuating end of the automatic control unit 4 through the L-shaped plate 8, so that the automatic control unit 4 can drive the entire marking assembly to rise and fall synchronously. After the marker pen 5 is inserted into the mounting cylinder 13, tightening the locking screw 12 on the mounting cylinder 13 can firmly fix the marker pen 5 to prevent deviation or falling off during marking. When the testing device 1 determines that the wire harness is qualified, the automatic control unit 4 receives the signal and drives the actuating end to descend, which drives the marker pen 5 to move down synchronously until its pen tip extends into the corresponding marking slot 19 at the upper end of the connecting socket 7 to mark the high voltage integrated wire harness as qualified.

[0025] The working principle of this utility model is as follows: When performing high-voltage integrated wire harness testing, the testing device 1 establishes an electrical path with the connecting socket 7 through the wire 2. After the plug of the high-voltage integrated wire harness to be tested is connected to the connecting socket 7, the testing device 1 transmits a preset test electrical signal to the wire harness and receives the electrical performance data fed back by the connecting socket 7, thereby completing the testing and qualification judgment of the product's withstand voltage and insulation performance.

[0026] When the testing equipment 1 determines that the product is qualified, the testing equipment 1 sends an electrical signal to the automatic control unit 4. The automatic control unit 4 drives the L-shaped plate 8 at its action end to descend synchronously, which in turn moves the marking pen 5 in the mounting cylinder 13 on the L-shaped plate 8 downward. The tip of the marking pen 5 extends into the corresponding marking slot 19 at the upper end of the connector 7, completing the qualified marking of the high-voltage integrated wire harness plug. After the marking is completed, the automatic control unit 4 drives the marking assembly to reset, waiting to execute the next marking action.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
