[0001] The utility model relates to the technical field of motor components, in particular to an automobile motor terminal connection structure. Background Art

[0002] Automotive motor terminals are the interface devices used to connect the electric motor to other components of the electric power system, typically located at the motor's end. These terminals provide access points for power, control signals, and ground wires to ensure proper motor operation and communication with other vehicle systems. The connection between the alternator's current output terminals and the vehicle's wiring harness is typically bolted. Bolts are typically secured to the alternator by crimping, threading, or riveting to the positive plate.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: an automobile motor terminal connection structure, including a terminal body 1, a fixing seat 2 is fixedly connected to the upper surface of the terminal body 1, a fixing bolt 3 is connected to the inner thread of the fixing seat 2, the outer wall of the fixing bolt 3 is threadedly connected to the inner part of the terminal body 1, a protective component is provided on the outer wall of the fixing bolt 3, a guide piece 5 is rotatably connected to the outer wall of the fixing bolt 3, a first spring 6 is provided inside the fixing bolt 3, one end of the first spring 6 is fixedly connected to the inner part of the fixing bolt 3, and the other end of the first spring 6 is fixedly connected to the first push plate 7, the first push plate 7 The outer wall of the terminal body 1 is fixedly connected to the limit block 8, the outer wall of the limit block 8 is slidably connected to the inside of the fixing bolt 3, the inside of the terminal body 1 is fixedly connected to the sliding sleeve 9, the inside of the sliding sleeve 9 is provided with a second spring 10, the inside of the sliding sleeve 9 is slidably connected to the second push plate 11, the upper surface of the second push plate 11 is fixedly connected to the ejector rod 12, the outer wall top of the ejector rod 12 is fixedly connected to the top plate 13, and the outer wall of the top plate 13 is slidably connected to the inside of the fixing bolt 3; one end of the second spring 10 is fixedly connected to the inside of the sliding sleeve 9, and the other end of the second spring 10 is fixedly connected to the lower surface of the top plate 13;

[0024] Specifically, when the connection between the terminal and the fixing bolt 3 needs to be reinforced, the fixing bolt 3 is rotated toward the interior of the terminal body 1, causing the fixing bolt 3 to drive the first push plate 7 to push the top plate 13. This causes the first push plate 7 to compress the first spring 6, while the top plate 13 pushes the push rod 12, thereby pushing the second push plate 11 to slide within the sliding sleeve 9 and compressing the second spring 10. This utilizes the elastic force of the springs, making the connection structure more stable and reliable when subjected to force. At the same time, the limit blocks 8 fixed on both sides of the first push plate 7 limit the position of the first push plate 7, ensuring stability and accuracy during the connection process. The push of the push rod 12 ensures that the second push plate 11 slides within the sliding sleeve 9, while compressing the second spring 10, further strengthening the connection structure. Finally, the elastic forces of the first spring 6 and the second spring 10 push back the first push plate 7 and the top plate 13, respectively, ensuring that the connection structure is in a stable state. This not only ensures the safety of the terminal during use, improves the stability of the connection structure, but also extends the service life of the terminal.

[0025] Reference Figure 1 and Figure 2 , the protective assembly includes a gasket 4, the inner portion of which is rotatably connected to the outer wall of the fixing bolt 3;

[0026] Specifically, the gasket 4 is installed between the fixing bolt 3 and the guide vane 5 so that the gasket 4 can prevent the fixing bolt 3 from wearing the guide vane 5 when rotating, thereby achieving the effect of protecting the guide vane 5.

[0027] Reference Figure 1 、 Figure 2 and Figure 4 , the terminal body 1 is rotatably connected to a threaded rod 14, one end of the threaded rod 14 is fixedly connected to a first knob 15; the outer wall of the first knob 15 is threadedly connected to a slider 16, and the outer wall of the slider 16 is slidably connected to the inside of the terminal body 1; the outer wall of the slider 16 is fixedly connected to a sorting box 17, and a third spring 18 is provided inside the sorting box 17; one end of the third spring 18 is fixedly connected to the inside of the sorting box 17, and the other end of the third spring 18 is fixedly connected to a baffle 19; the interior of the sorting box 17 is rotatably connected to a rotating shaft 20, one end of the rotating shaft 20 is fixedly connected to a second knob 21, the outer wall of the rotating shaft 20 is rotatably connected to a limiting ring 22, and the outer wall of the limiting ring 22 is fixedly connected to the inside of the sorting box 17;

[0028] Specifically, when it is necessary to organize the circuits on the terminal, by turning the second knob 21, the rotating shaft 20 is driven to rotate, so that the circuit is wound inside the organizing box 17. At the same time, the third spring 18 pushes the baffle 19 to clamp the circuit and restrict it. This ensures safety and stability during the circuit organization process. Then, the first knob 15 is turned to drive the threaded rod 14 to rotate, so that the slider 16 slides on the outer wall of the threaded rod 14, and at the same time adjusts the position of the circuit inside the terminal body 1. This makes the organization of the circuit more orderly and convenient, and improves the practicality of the connection structure. At the same time, this also ensures safety when the circuit is wound, avoiding entanglement and confusion of the circuit. This not only improves the practicality of the connection structure, but also can effectively organize and summarize the circuits. At the same time, the orderly organization of the circuit is achieved, making the circuit layout on the terminal clearer and more standardized.

[0029] Working principle: When it is necessary to strengthen the connection between the terminal and the fixing bolt 3, the fixing bolt 3 is rotated toward the inside of the terminal body 1, so that the fixing bolt 3 can drive the first push plate 7 to push the top plate 13, thereby making the first push plate 7 compress the first spring 6, and the top plate 13 can push the top rod 12, wherein the limit blocks 8 fixed on both sides of the first push plate 7 can limit the position of the first push plate 7, and the top rod 12 can push the second push plate 11, so that the second push plate 11 can slide inside the sliding sleeve 9 while compressing the second spring 10, and then the elastic force of the first spring 6 and the second spring 10 pushes the first push plate 7 and the top plate 13 back respectively, thereby pushing the connection between the fixing bolt 3 and the terminal body 1 tighter, thereby achieving a stable fixing screw. The connection effect between the bolt 3 and the terminal ensures the safety of the terminal during use, improves the stability of the connection structure, and extends the service life of the terminal. When it is necessary to organize the lines on the terminal, the second knob 21 is turned to drive the rotating shaft 20 to rotate, so that the lines are wound inside the organizing box 17. At the same time, the third spring 18 pushes the baffle 19 to clamp the lines, thereby restricting the lines to a certain extent. Then, the first knob 15 is turned to drive the threaded rod 14 to rotate, so that the slider 16 can slide on the outer wall of the threaded rod 14, and at the same time slide inside the terminal body 1 to adjust the position of the lines, thereby achieving the effect of orderly organizing the lines, improving the practicality of the connection structure, ensuring the safety when winding the lines, and effectively organizing and summarizing the lines.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
