Abstract
Description
Technical Field
[0001] This utility model relates to the field of plug testing, specifically a plug testing fixture. Background Technology
[0002] In the field of power equipment, the assembly of cable terminations and matching plugs is a common operation. To ensure the reliability of electrical connections, a series of electrical performance tests (such as conductivity, insulation resistance, withstand voltage, etc.) need to be performed on the assembly after assembly or before leaving the factory.
[0003] When conducting such tests, the plug is usually suspended and connected to the cable terminal. Since the plug itself has a certain weight, and the connection between it and the terminal may not be rigidly locked, the plug is prone to falling or tilting due to its own weight or the drag force of the test cable during the test. This can prevent the cylinder output from aligning the plug directly with the cable terminal, resulting in poor contact between the plug and the cable terminal, fluctuations in test data, and affecting the effectiveness and accuracy of the test.
[0004] Therefore, a plug testing fixture is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a plug testing fixture to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A plug testing fixture includes a test frame with a test component. The test component includes a support fixed to the upper end of the test frame. A cable terminal is fixed to one end of the support, and a cylinder is fixed to the other end. The shaft of the cylinder output end is aligned with the shaft of the cable terminal. A connecting rod is rotatably mounted inside the test frame and is located below the support. A support component for supporting the plug is fixed to the connecting rod.
[0008] Preferably, multiple sets of the test components and support components are provided, and the test components and support components are arranged in a linear array, with each set of support components corresponding to a set of test components.
[0009] Preferably, the support assembly includes a fixed arm, one end of which is fixedly connected to the connecting rod and is perpendicular to the connecting rod, and the other end of which is fixedly connected to a support rod, which is parallel to the connecting rod and is located between the cable terminal and the cylinder output end.
[0010] Preferably, the bracket is U-shaped, with multiple sets of casters installed at the bottom of the test frame, a push plate fixed to the output end of the cylinder, and a rubber pad fixed to the push plate.
[0011] Preferably, both ends of the test frame are fixedly connected to fixed plates, and both ends of the connecting rod are rotatably installed with two sets of fixed plates respectively. Both ends of the connecting rod are coaxially fixedly connected to driven gears. One side of each set of fixed plates is rotatably installed with a driving gear for meshing with the driven gear. Both sets of fixed plates are fixedly connected to a servo motor for driving the driving gear to rotate.
[0012] Preferably, a support plate is fixedly connected to the middle of the test frame, and the connecting rod passes through the support plate.
[0013] The beneficial effects of this utility model are:
[0014] This invention connects one end of the plug to the cable terminal head.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] A plug testing fixture, such as Figures 1-4 As shown, the test includes a test frame 1, on which a test assembly is provided. The test assembly includes a bracket 2, which is fixed to the upper end of the test frame 1. One end of the bracket 2 is fixedly connected to a cable terminal head 3, and the other end is fixedly connected to a cylinder 4 (model MAL40×50). The shaft of the output end of the cylinder 4 and the shaft of the cable terminal head 3 are on the same straight line to ensure the centering of the thrust. A connecting rod 13 is rotatably installed inside the test frame 1. The connecting rod 13 is located below the bracket 2, and a support assembly for supporting the plug is fixedly connected to the connecting rod 13.
[0024] First, rotate connecting rod 13. Connecting rod 13 drives the support assembly to rise. Adjust the top height of the support assembly according to the installation height of the plug, and align one end of the plug with the cable terminal 3. The support assembly can provide stable support for the plug before and during the test, ensuring that the axis of the plug is coaxial with the axis of the cable terminal 3 and the output end of the cylinder 4, preventing the plug from falling or tilting downwards. This allows the cylinder 4 to accurately press the plug straight into the cable terminal 3 when it is pushed forward, forming a stable and reliable electrical contact, thereby ensuring the accuracy and validity of the subsequent electrical performance test data.
[0025] Multiple sets of test components and support components are provided, and both test components and support components are arranged in a linear array. Each set of support components corresponds to a set of test components.
[0026] Multiple test components can test multiple plugs simultaneously, and multiple support components can support multiple plugs.
[0027] The support assembly includes a fixed arm 14, one end of which is fixedly connected to the connecting rod 13 and is perpendicular to the connecting rod 13. The other end of the fixed arm 14 is fixedly connected to a support rod 15, which is parallel to the connecting rod 13 and is located between the cable terminal 3 and the output end of the cylinder 4.
[0028] The connecting rod 13 drives the support rod 15 to rise or fall via the fixed arm 14. The support rod 15 rotates around the axis of the connecting rod 13 and supports the bottom of the plug.
[0029] The bracket 2 is U-shaped, and multiple sets of casters 7 are installed at the bottom of the test frame 1. A push plate 5 is fixed to the output end of the cylinder 4, and a rubber pad 6 is fixed to the push plate 5.
[0030] The U-shaped bracket 2 has an open end for easy installation of the plug, the caster wheel 7 facilitates the movement of this test fixture, the push plate 5 evens out the thrust at the output end of the cylinder 4, allowing the cylinder 4 to press tightly against one end of the plug via the push plate 5, and the rubber pad 6 prevents the push plate 5 from squeezing the plug and causing damage.
[0031] The test frame 1 has fixed plates 9 at both ends. The two ends of the connecting rod 13 are rotatably mounted to the two sets of fixed plates 9 respectively, and the two ends of the connecting rod 13 are coaxially fixed with driven gears 12. The two sets of fixed plates 9 have rotatably mounted on one side of the driving gears 11 for meshing with the driven gears 12. The two sets of fixed plates 9 have servo motors 10 fixed on them for driving the driving gears 11 to rotate.
[0032] The fixed plate 9 supports the connecting rod 13 and provides installation conditions for the connecting rod 13. The output end of the servo motor 10 (model 60ST-M01330A) drives the drive gear 11 to rotate, so that the drive gear 11 meshes with the driven gear 12. The driven gear 12 drives the connecting rod 13 to rotate. When the servo motor 10 stops running, it can position the drive gear 11. The drive gear 11 cannot rotate automatically, so that the support assembly can be positioned.
[0033] A support plate 8 is fixedly connected to the middle of the test frame 1, and the connecting rod 13 passes through the support plate 8. The support plate 8 supports the middle of the connecting rod 13 to prevent the middle of the connecting rod 13 from bending downward due to gravity.
[0034] The working principle of the plug testing fixture provided by this utility model is as follows:
[0035] The operator first starts the servo motor 10, driving the drive gear 11, driven gear 12, and connecting rod 13 to rotate, so that all support components rotate synchronously to a suitable support position. The plug to be tested is placed one by one on the support rod 15 of each support component. The support rod 15 provides stable bottom support for the plug, effectively preventing it from falling or tilting downwards. The cylinder 4 is controlled to move, and the output end of the cylinder 4 drives the push plate 5 to extend smoothly. The push plate 5 precisely pushes against the rear end of the plug that has been lifted and centered by the support rod 15, applying a smooth axial thrust, pressing the plug flat on the cable terminal 3 to form a stable and reliable connection. A series of tests on the plug can then begin.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
