Description

Technical Field

[0001] This application relates to the field of locomotive technology, and in particular to a high-voltage connector testing device. Background Technology

[0002] In DC locomotive operating systems, high-voltage connectors are used to ensure the continuity of high-voltage circuits during locomotive coupling operations. The performance of high-voltage connectors directly affects the stability and safety of the locomotive's power supply system. Because high-voltage connectors are exposed to high voltage, high-frequency vibration, and complex outdoor environments for extended periods, they are prone to various problems such as mechanical wear, oxidation, and loosening. Therefore, they need to be periodically removed from the locomotive for disassembly inspection, component repair and replacement, and performance parameter testing to eliminate potential faults.

[0003] In related technologies, high-voltage connectors are often tested using testing platforms. However, because testing platforms cannot simulate the locomotive operating conditions of high-voltage connectors in actual application scenarios, the test results are inaccurate, and the testing operations are cumbersome and inefficient. Utility Model Content

[0004] Therefore, it is necessary to provide a high-voltage connector testing device to address the problems of inaccurate test results and inconvenient test operations for high-voltage connector maintenance.

[0005] A high-voltage connector testing device, the high-voltage connector testing device comprising:

[0006] Mounting base;

[0007] The first test component includes a movable seat and a limiting member. The movable seat is movably connected to the mounting base, and the limiting member is fixedly connected to the movable seat. The fixed seat and the movable seat form a receiving cavity.

[0008] A first locking component is connected to the movable seat and is configured to move relative to the movable seat to approach or move away from the receiving cavity.

[0009] In one embodiment, the limiting member has a ring-shaped structure, and the middle region of the limiting member forms the receiving cavity.

[0018] The aforementioned high-voltage connector testing device utilizes a receiving cavity to stably accommodate the high-voltage connector, and with the fixing effect of the first locking component, prevents the high-voltage connector from shifting during testing, thus ensuring accurate testing.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figures 1 to 4 As shown, a schematic diagram of the structure of a high-voltage connector testing device 10 in one embodiment of this application is shown. The high-voltage connector testing device 10 provided in one embodiment of this application includes a mounting base 100, a first testing component 200 and a first locking component 300.

[0038] Mounting base 100 serves as the supporting foundation for the entire high-voltage connector testing device 10, providing stable support for other components to ensure the stability of the testing process.

[0039] The first test assembly 200 includes a movable seat 210 and a limiting member 220. The movable seat 210 is movably connected to the mounting base 100, allowing the movable seat 210 to move within a certain range relative to the mounting base 100, simulating different movement states of the high-voltage connector on the locomotive. The limiting member 220 is fixedly connected to the movable seat 210, and the fixed seat and the movable seat 210 together form a receiving cavity 201. The shape and size of the receiving cavity 201 are adapted to the high-voltage connector to be tested, used to position the high-voltage connector and ensure that the high-voltage connector does not shift significantly during testing.

[0040] The first locking component 300 is connected to the movable seat 210 and is configured to move relative to the movable seat 210 to approach or move away from the receiving cavity 201. When the high-voltage connector is placed inside the receiving cavity 201, adjusting the first locking component 300 to move it closer to the receiving cavity 201 can secure the high-voltage connector and prevent it from loosening during testing. When it is necessary to remove or adjust the high-voltage connector, simply adjust the first locking component 300 to move it away from the receiving cavity 201.

[0041] Through the above structural design, the high-voltage connector testing device 10 of this application embodiment can stably accommodate the high-voltage connector using the receiving cavity 201, and with the fixing effect of the first locking component 300, the high-voltage connector is not easily displaced during testing, thus enabling accurate testing. Furthermore, since the movable seat 210 is movably connected to the mounting base 100, the high-voltage connector can perform corresponding movements, thereby simulating the locomotive's movement state and achieving simulated locomotive dynamic testing, improving testing accuracy. Moreover, the high-voltage connector testing device 10 is convenient to use and operate; maintenance personnel can easily complete the installation, fixing, testing, and disassembly processes of the high-voltage connector, which helps improve maintenance and testing efficiency.

[0042] Optionally, see Figure 1 As shown, in some embodiments, the limiting member 220 has an annular structure, and the middle region of the limiting member 220 forms a receiving cavity 201. For example, the limiting member 220 can be configured as a circular ring shape, a square annular structure, etc., to adapt to different types of high-voltage connectors. In this embodiment, the receiving cavity 201 formed by the annular limiting member 220 can limit the high-voltage connector from the circumference, which can minimize the tilting or displacement of the high-voltage connector during the test due to uneven limiting force, further improving the stability of the high-voltage connector in the receiving cavity 201, ensuring that the high-voltage connector is always in the preset test position during the test, thereby improving the accuracy of the test results. In addition, the annular structure makes the opening direction of the receiving cavity 201 clear, which makes it easy for maintenance personnel to quickly put the high-voltage connector into or take out the receiving cavity 201, further improving the convenience of operation.

[0043] Optionally, see Figures 2 to 4As shown, in some embodiments, the limiting member 220 includes a first limiting portion 221 and a second limiting portion 222, which are spaced apart and both are fixedly connected to the movable seat 210. Specifically, the first limiting portion 221 includes a side wall 2211 and a top cover 2212. The side wall 2211 is connected to the movable seat 210, and the top cover 2212 is connected to the end of the side wall 2211 away from the movable seat 210. The top cover 2212, the side wall 2211, the second limiting portion 222, and the movable seat 210 form a receiving cavity 201. For example, the side wall 2211 and the second limiting portion 222 of the first limiting portion 221 can both be configured as a semi-enclosed structure, and their openings are opposite to each other. The side wall 2211 and the second limiting portion 222 both extend upward along the surface of the movable seat 210 to form a certain height to limit the side of the high-voltage connector. The top cover 2212 of the first limiting part 221 is connected to the end of the side wall 2211 away from the movable seat 210. The shape of the top cover 2212 is adapted to the top shape of the side wall 2211, and can completely cover part or all of the top area of ​​the side wall 2211, so that part of the high-voltage connector structure can extend between the top cover 2212 and the side wall 2211 to limit the high-voltage connector and prevent the high-voltage connector from moving upward during the test. Thus, the side wall 2211 and the top cover 2212 of the first limiting part 221 limit the high-voltage connector from the side and the top, respectively, and the second limiting part 222 limits the high-voltage connector from the other side, forming a multi-directional limiting structure, which can more comprehensively restrict the movement of the high-voltage connector, thereby reducing the shaking of the high-voltage connector during the test and improving the stability and accuracy of the test.

[0044] Furthermore, in some embodiments, the number of first locking components 300 is several. The specific number of first locking components 300 can be determined according to the size of the high-voltage connector and the fixing requirements, ensuring that sufficient and uniform fixing force can be provided to the high-voltage connector. Several first locking components 300 are distributed on the outer periphery of the receiving cavity 201. For example, several first locking components 300 can be evenly spaced along the circumference of the receiving cavity 201.

[0045] Furthermore, see Figures 2 to 4 As shown, at least one first locking component 300 is disposed on the side of the second limiting part 222 away from the first limiting part 221, so that the first locking component 300 at this position can directly act on the side of the high-voltage connector near the second limiting part 222, thereby cooperating with the first limiting part 221 to clamp the high-voltage connector in the receiving cavity 201, ensuring that the high-voltage connector is fixed and secure, so as to test the high-voltage connector.

[0046] Further, see Figures 2 to 4As shown, in some embodiments, the first locking assembly 300 includes a first fixing member 310 and a first locking member 320. The first fixing member 310 is fixedly connected to the movable seat 210, for example, by welding or by bolting, so that the first fixing member 310 remains fixed relative to the movable seat 210. The first locking member 320 passes through the first fixing member 310 and is threadedly connected to the first fixing member 310. For example, a threaded hole is provided through the first fixing member 310, and the first fixing member 310 is threadedly connected to the first locking member 320 through the threaded hole, which facilitates the adjustment of the first locking member 320 for telescopic movement. Furthermore, the axial direction of the threaded hole on the first fixing member 310 is towards the receiving cavity 201, thereby providing guidance for the installation and movement of the first locking member 320, allowing the first locking member 320 to move along the threaded hole toward the receiving cavity 201, and then using the first locking member 320 to abut against the high-voltage connector located in the receiving cavity 201 to lock the high-voltage connector.

[0047] Further, see Figures 1 to 4 As shown, in some embodiments, the first test component 200 further includes a support plate 230, which may be a flat plate structure. The support plate 230 is connected to the mounting base 100, and the movable seat 210 is movably connected to the support plate 230, such as through a sliding connection or a rotating connection. The specific connection method can be selected according to the test requirements to meet the requirement that the movable seat 210 performs a preset movement relative to the support plate 230. In this embodiment, the support plate 230 is provided between the movable seat 210 and the mounting base 100. The support plate 230 can guide and support the movement of the movable seat 210, while also preventing wear caused by direct contact between the movable seat 210 and the mounting base 100, thus extending the service life of the movable seat 210. In addition, when the movable seat 210 wears out, only the movable seat 210 or the support plate 230 needs to be maintained, without replacing the entire mounting base 100, which helps to reduce maintenance costs. Meanwhile, if it is necessary to adjust the installation position of the movable seat 210 or replace it with a different type of movable seat 210, this can also be achieved by adjusting the position of the support plate 230 or replacing it with a suitable support plate 230. This can improve the installation flexibility of the high-voltage connector testing device and thus improve the efficiency of maintenance and testing.

[0048] Further, see Figures 1 to 4As shown, in some embodiments, the movable seat 210 is rotatably connected to the support plate 230, and the rotation axis of the movable seat 210 is perpendicular to the support plate 230. For example, the movable seat 210 can be configured as a ball bearing disc structure, allowing it to rotate relative to the support plate 230; or, for example, a bearing seat can be provided on the support plate 230, and a rotating shaft adapted to the bearing seat can be provided at the bottom of the movable seat 210, enabling the movable seat 210 to rotate flexibly relative to the support plate 230 through the bearing. Since the rotation axis of the movable seat 210 is perpendicular to the support plate 230, the movable seat 210 can rotate 360 ​​degrees in a plane parallel to the support plate 230. The movable seat 210 can drive the high-voltage connector in the receiving cavity 201 to rotate in a plane parallel to the support plate 230, thereby accurately simulating the left and right swinging state of the high-voltage connector when the locomotive is traveling on a curve. Therefore, through this simulation test, maintenance personnel can more comprehensively detect the performance parameters of the high-voltage connector under different swing angles, promptly identify potential problems that may occur during the swing process, avoid these problems from being exposed only after the high-voltage connector is installed on the train, reduce unnecessary rework and maintenance, and ensure the quality and safety of locomotive parts.

[0049] Further, see Figures 2 to 4 As shown, in some embodiments, the high-voltage connector testing device 10 further includes a second locking assembly 400, which includes a second fixing member 410 and a second locking member 420. The second fixing member 410 is fixedly connected to the support plate 230, for example, by welding or bolting, so that the second fixing member 410 remains fixed relative to the support plate 230. The second locking member 420 passes through the second fixing member 410 and is threadedly connected to the second fixing member 410, so that the second locking member 420 can move relative to the support plate 230 to abut or disengage from the movable seat 210. For example, a threaded hole is provided through the second fixing member 410, and the second fixing member 410 is threadedly connected to the second locking member 420 through the threaded hole, which facilitates the adjustment of the extension and retraction movement of the second locking member 420. Furthermore, the axial direction of the threaded hole on the second fixing member 410 is towards the movable seat 210, thereby providing guidance for the installation and movement of the second locking member 420, so that the second locking member 420 can move along the threaded hole toward the movable seat 210. When the second locking member 420 abuts against the edge of the movable seat 210, the second locking member 420 can restrict the rotation of the movable seat 210 through friction; when the second locking member 420 disengages from the movable seat 210, the movable seat 210 can rotate freely. Therefore, after the movable seat 210 is adjusted to the preset test angle, by rotating the second locking member 420 to abut against the movable seat 210, the rotation of the movable seat 210 can be restricted by friction, thus stably fixing the movable seat 210 at that angle position. This ensures that the high-voltage connector remains in the preset swing angle state during the test, avoiding test interruption or test data deviation due to accidental rotation of the movable seat 210, and improving the stability of the test process and the accuracy of the test results.

[0050] Optionally, to enhance the locking effect, a wear-resistant pad may be provided at the end of the second locking member 420 near the movable seat 210. The wear-resistant pad is made of a material with a high coefficient of friction, such as rubber or asbestos, to increase the friction between it and the movable seat 210 and ensure reliable locking.

[0051] Furthermore, in some embodiments, the high-voltage connector testing device 10 further includes at least one hoisting hand ring 500, which is connected to the mounting base 100. For example, see... Figures 1 to 4 As shown, two lifting handles 500 are symmetrically arranged at both ends of the mounting base 100 to ensure the balance of the high-voltage connector testing device 10 during hoisting and to prevent tilting. Of course, in other optional embodiments, the number of lifting handles 500 is not limited to two; for example, there can be three, four, five, or even more. Furthermore, the structure of the lifting handles 500 can be set as semi-circular or U-shaped to facilitate hook attachment to the hoisting equipment. Using the lifting handles 500 to hoist and move the high-voltage connector testing device 10 can reduce the labor intensity of maintenance personnel, while also enabling rapid handling, reducing handling time, and improving work efficiency.

[0052] Further, see Figures 1 to 4As shown, in some embodiments, the high-voltage connector testing device 10 further includes a second testing component 600. The second testing component 600 can be used to independently fix the high-voltage connector, allowing for simultaneous maintenance and testing of two high-voltage connectors, thus improving maintenance and testing efficiency. The second testing component 600 is spaced apart from the first testing component 200 on the mounting base 100, and the second testing component 600 and the first testing component 200 are mirror-symmetrical. Specifically, the structure of the second testing component 600 is the same as that of the first testing component 200, and the connection method and function of each component of the second testing component 600 are consistent with those of the first testing component 200. The distance between the second testing component 600 and the first testing component 200 on the mounting base 100 can be determined according to the actual spacing of the high-voltage connectors during simulated locomotive docking, ensuring that the docking state of the high-voltage connectors of two adjacent locomotives can be realistically simulated. Furthermore, the mirror-symmetry between the second testing component 600 and the first testing component 200 allows the high-voltage connectors fixed to the first testing component 200 and the high-voltage connectors fixed to the second testing component 600 to be docked in a symmetrical posture for testing, which better reflects the actual operation of the locomotive. Therefore, by setting up a second test component 600 that is mirror-symmetrical to and spaced apart from the first test component 200, two high-voltage connectors can be installed simultaneously to achieve docking tests of the two high-voltage connectors. This can realistically simulate the working state of the high-voltage connectors after locomotive docking, including the locomotive's left and right swaying on curves and the test state before and after buffer docking. This is beneficial for timely detection of problems in the docking process and reducing the failure rate of the high-voltage connectors.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
