Description

Technical Field

[0001] This utility model relates to the field of terminal block load testing technology, specifically to a holding force load testing device. Background Technology

[0002] In the field of electrical connections, terminals are key components for achieving circuit connections, and their holding force performance directly affects the stability and safety of electrical systems. Currently, the industry commonly uses holding force (suspension load) testing machines to test their performance. Horizontal tensile force tests are used to evaluate the terminal's ability to hold the wire, ensuring that the terminal will not experience problems such as wire detachment or poor contact in practical applications.

[0003] However, existing testing technologies have significant limitations. In actual working conditions, the force direction of the terminals is complex and varied. For example, in scenarios such as automobile engine compartments and industrial automation equipment, the terminals may be subjected to vertical, tilted, or even dynamically changing angles of tension due to factors such as mechanical vibration and spatial layout. However, traditional holding force (suspension) testing machines can only simulate horizontal force. Even if the magnitude of the applied force is the same, they cannot accurately reflect the actual holding force of the terminals at other angles.

[0004] Based on this, the present invention designs a holding force load detection device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a holding force load detection device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A holding force load detection device includes a base and a load detection machine, wherein the load detection machine is located on the top surface of the base, and clamping screws are installed on the surfaces of both the base and the load detection machine. The device also includes an adjustment component and a limiting component.

[0008] The adjustment component is located between the base and the load testing machine, and is used to adjust the angle between the load testing machine and the base;

[0009] The limiting components are symmetrically installed on the side wall of the load testing machine and are used to stabilize the use of the load testing machine.

[0010] Furthermore, a fixing block is fixedly connected to the top surface of the base, and an installation port is opened on one side of the bottom end of the load testing machine. The adjustment component includes a worm gear, and a symmetrical support frame is fixedly connected to the side wall of the fixing block. A rotating shaft is rotatably connected between the two support frames, and the rotating shaft passes through the center of the installation port. The worm gear is fixedly connected to the surface of the rotating shaft, and the worm gear rotates on the inner wall of the installation port through the rotating shaft. A worm is meshed with the bottom surface of the worm gear, and a groove is opened on the top surface of the fixing block. The two ends of the worm are rotatably connected to the inner wall of the groove through bearings.

[0011] Furthermore, the mounting port is L-shaped.

[0012] Furthermore, the mounting port, worm gear, groove, and worm are all symmetrical.

[0013] Furthermore, a motor is fixedly connected to the surface of the fixing block, and the ends of the two worm gears away from the inside of the groove extend through the outside of the fixing block. Pulleys are fixedly connected to the ends of the two worm gears away from the groove, and the outer surfaces of the two pulleys are connected by belt drive. The output end of the motor is fixedly connected to the end of one of the worm gears.

[0014] Furthermore, both ends of the rotating shaft are fixedly connected to the support frame through the support frame. A rod is inserted into the end of the support away from the rotating shaft. The side wall of the fixing block is symmetrically provided with fan-shaped limiting grooves, and the rod is inserted into the limiting groove.

[0015] Furthermore, the bracket has an insertion port at the end away from the pivot, the insertion rod is normally located on the inner wall of the insertion port, and a pull block is fixedly connected to the end of the insertion rod away from the fixing block, and the diameter of the pull block is larger than the diameter of the insertion port.

[0016] Furthermore, both the insertion rod and the limiting groove are pentagonal, and the insertion port is circular.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the holding force load detection device realizes the multi-angle rotation of the load detection machine by adjusting the worm gear and worm meshing rotation structure of the component, and fixes the detection angle by combining the plug rod and limit groove structure of the limit component.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In some embodiments, please refer to the accompanying drawings. Figures 1-4A holding force load detection device includes a base 1 and a load detection machine 2. The load detection machine 2 is located on the top surface of the base 1, and clamping screws are installed on the surfaces of both the base 1 and the load detection machine 2. The device also includes an adjustment assembly and a limiting assembly. The adjustment assembly is located between the base 1 and the load detection machine 2 and is used to adjust the angle between the load detection machine 2 and the base 1. The limiting assembly is symmetrically installed on the side walls of the load detection machine 2 and is used to stabilize the use of the load detection machine 2. One clamping screw is fixedly connected to the top surface of the base 1. A linear motor module is fixedly installed on the surface of the load detection machine 2, and another clamping screw is fixedly connected to the slider of the linear motor module for clamping terminal blocks. The clamping screws in this technical solution adopt a double-clamping plate structure with threaded rod guidance. Figure 1 As shown, the two clamping screws have one clamping plate facing the load testing machine 2 and the other clamping plate attached to it. Both sides are fixedly connected with fixing blocks and threaded sleeves. One clamping screw's clamping plate is fixed to the slider surface of the linear motor module. The other two clamping screws have notches on the same side of the clamping plates, and the opening directions are opposite. This can be used to allow the wire to bend out from the notch when clamping the terminal block. Since the threaded rod guide clamping plate structure is existing technology, it will not be described in detail here.

[0027] In some embodiments, such as Figures 1-4As shown, in a preferred embodiment of this utility model, a fixing block 3 is fixedly connected to the top surface of the base 1, and a symmetrical mounting port 4 is provided at the bottom edge of the load testing machine 2. The mounting port 4 extends from the side wall of the load testing machine 2 to the bottom surface of the load testing machine 2. The adjustment assembly includes a worm gear 5 that rotates at the center of the inner wall of the mounting port 4. A symmetrical support frame 7 is fixedly connected to the side wall of the fixing block 3, and a rotating shaft 6 is fixedly connected between the two support frames 7 through the inner wall of the bearing. Both ends of the rotating shaft 6 are located on the same horizontal line as the center of the mounting port 4 and penetrate through the mounting port 4. The penetration point is also connected to the load testing machine 2. The housing of the testing machine 2 is fixed. A worm 9 is meshed with the bottom surface of the worm wheel 5. A groove 8 is formed on the top surface of the fixing block 3. The two ends of the worm 9 are rotatably connected to the inner wall of the groove 8 via bearings. In this technical solution, the number of teeth on the worm wheel 5 is four times the number of worm heads on the worm 9, allowing the worm wheel 5 to rotate 90° for every revolution of the worm 9. This enables the load testing machine 2 to be adjusted from a vertical to a maximum horizontal position. In use, the rotation of the worm 9 engages with the worm wheel 5, resulting in the rotation of the shaft 6 causing the load testing machine 2 to rotate at different angles. Additionally, the worm wheel 5… Two worm gears 9 are provided, arranged symmetrically, to provide a certain degree of support stability when the load testing machine 2 is flipped. A motor base is fixed to the surface of the fixing block 3, and a motor 12 is fixedly connected to the surface of the fixing block 3 through the motor base. The ends of the two worm gears 9 away from the inside of the groove 8 extend through the outside of the fixing block 3, and pulleys 10 are fixedly connected to the ends of the two worm gears 9 away from the groove 8. The outer surfaces of the two pulleys 10 are connected by a belt 11. The output end of the motor 12 is fixedly connected to the end of one of the worm gears 9. Driven by the motor 12, the load testing machine 2 can be rotated. The two worm gears 9 rotate together, causing the worm wheel 5 to rotate, which in turn causes the rotating shaft 6 to rotate and rotate the load testing machine 2. The insertion rod 15 and the limiting groove 17 are both pentagonal, and the insertion port 14 is circular. The pentagonal structure makes the insertion state of the insertion rod 15 and the limiting groove 17 more stable. When the rotating shaft 6 rotates, the bracket 13 swings on both sides of the fixed block 3. After the motor 12 stops driving, in order to prevent the motor 12 from rotating due to the tilting gravity of the load testing machine 2, the insertion rod 15 can be inserted into the corresponding limiting groove 17 to maintain the angular stability of the load testing machine 2 after adjustment.

[0028] In some embodiments, such as Figures 2-4 As shown, in a preferred embodiment of the present invention, both ends of the rotating shaft 6 are connected to the support frame 7 and fixedly connected to the bracket 13. The end of the bracket 13 away from the rotating shaft 6 is provided with a rod 15. The side wall of the fixing block 3 is symmetrically provided with fan-shaped limiting grooves 17. The rod 15 is inserted into the limiting grooves 17. The end of the bracket 13 away from the rotating shaft 6 is provided with a socket 14. The rod 15 is normally located on the inner wall of the socket 14. The end of the rod 15 away from the fixing block 3 is fixedly connected to a pull block 16, and the diameter of the pull block 16 is larger than the diameter of the socket 14.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
