[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1-4 This is a schematic diagram of a high-current connector according to a preferred embodiment of the present invention. In this embodiment, a high-current connector includes a mounting plate 1. A first connecting cylinder 2 and a second connecting cylinder 3 are fixedly connected to the left and right ends of the mounting plate 1, respectively. A first connecting cavity 21 and a second connecting cavity 31 are respectively opened in the first connecting cylinder 2 and the second connecting cavity 31, and the first connecting cavity 21 and the second connecting cavity 31 are connected through the first connecting cavity 21 and the second connecting cavity 31. A threaded connecting hole 43 is opened on the surface of the connecting terminal 4 at one end of the first connecting cylinder 2, and a plug hole 44 is opened on the surface of the connecting terminal 4 at one end of the second connecting cylinder 3. An annular limiting ring 22 is fixedly connected to the inner wall of the first connecting cavity 21. A groove 41 is opened on the outer wall of the connecting terminal 4 at the opposite position of the annular limiting ring 22, and the groove 41 and the annular limiting ring 22 are engaged with each other to achieve axial fixation of the terminal, thereby replacing the complex multi-point fixing or additional fastener structure in traditional connectors. This design significantly reduces the number of internal parts, simplifies manufacturing processes and assembly procedures, and effectively lowers raw material costs as well as processing and assembly costs. The snap-fit ​​structure between the annular limiting ring 22 and the groove 41 is rationally designed; during assembly, reliable positioning and fixation can be achieved simply by inserting the connecting terminal 4 axially into place, making the assembly process simple and quick. Furthermore, this snap-fit ​​method has a certain tolerance for minor deviations in axial dimensions, reducing assembly precision requirements and improving assembly efficiency and yield.

[0025] In this embodiment, four rubber damping blocks 32 are evenly distributed circumferentially within the second connecting cavity 31, and their inner surfaces are tightly fitted to the outer wall of the connecting terminal 4. Two of the symmetrical damping blocks 32 have rectangular limiting grooves 33 formed on their surfaces. Limiting blocks 42 are welded to corresponding positions on the outer wall of the connecting terminal 4. During assembly, the limiting blocks 42 are embedded in the limiting grooves 33, preventing circumferential rotation of the terminal. Furthermore, the continuous contact between the damping blocks 32 and the outer wall of the connecting terminal 4 provides good radial support and damping. In particular, the cooperative design of the limiting blocks 42 and the limiting grooves 33, while providing circumferential limiting, further restricts the radial fretting and rotational tendencies of the connecting terminal under vibration conditions; thereby effectively improving mechanical stability and the long-term reliability of the electrical connection.

[0026] In this embodiment, the surface of the connecting terminal 4 has a threaded connecting hole 43 at one end of the first connecting cylinder 2 for bolting external wires; the surface of the connecting terminal 4 has a plug-in hole 44 at one end of the second connecting cylinder 3 for plugging in a matching terminal.

[0027] In this embodiment, multiple triangular reinforcing ribs 23 are radially welded to the outer wall of the first connecting cylinder 2, and the other end of the reinforcing ribs 23 is welded to the upper surface of the mounting plate 1. This significantly enhances the mechanical strength and rigidity of the connection between the first connecting cylinder 2 and the mounting plate 1, making it more resistant to insertion and extraction forces and external stresses, and improving the overall structural stability and durability of the connector.

[0028] In this embodiment, four mounting holes 11 are symmetrically opened around the surface of the mounting plate 1, which are mainly used to fix it to the equipment frame by bolts.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
