Any embodiment described as "exemplary" in this invention is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use this invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this invention can be implemented without using these specific details.

Therefore, this invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.

[0028] Example

[0029] Please see Figures 1-2 In this embodiment of the utility model, an assembly structure for a circular connector includes a fixed base 1 and a front cover 2 mounted on the fixed base 1. The structure is characterized by further including a housing 6 matching the diameter of the front cover. The fixed base is mainly used to mount the front cover 2. The front cover 2 serves as the connector insertion point during production assembly, ensuring the consistency of the diameter of the produced connectors. An inner post 3 is fixedly connected to the middle position inside the front cover 2. The edge of the inner post 3 is designed with an angle to facilitate insertion into the connector port. A crown spring 5 is installed inside the housing 6. When the inner post 3 is inserted into the housing 6, the elasticity of the crown spring 5 can engage the inner post 3, providing both electrical conductivity and auxiliary fixing.

[0030] One end of the crown spring 5 is designed with multiple horizontally extending fixing pieces 51. The fixing pieces 51 are integrally formed with the crown spring 5. The connection end between the housing 6 and the front cover 2 is provided with a converging groove 61. The outer edge of the converging groove 61 adopts an angled converging design 62. When the crown spring 5 is assembled into the housing 6, the end of the crown spring 5 with the fixing pieces 51 faces outward. When the crown spring 5 enters the housing 6 to a certain depth, the fixing pieces 51 will be horizontally placed on the inner edge of the converging groove 61 to install the crown spring 5 in place and prevent the crown spring 5 from continuing to slide down. The upper end of the housing 6 is covered with a rear cover 4. The inner diameter and height of the converging groove 61 can at least accommodate the fixing pieces 51 of the crown spring 5 and the rear cover 4 covering it.

[0031] Please refer to Figures 3-5 ,Depend on Figure 3 As can be seen from the cross-sectional view, after the crown spring 5 and the back cover 4 are assembled with the housing 6, the back cover 4 located inside the constriction groove 61, the fixing piece 51 covering the bottom, and the outside of the housing 6 are riveted together by the riveting process. At this time, the beveled constriction 62 is squeezed inward and together with the back cover 5 clamps the middle fixing piece 51, so that the back cover 4 and the crown spring 5 are fixed at the upper end of the housing 6 to form an external riveting structure. In addition, the riveting structure can enhance the stability of the connection, make the transmission of large current more stable, and the temperature rise more slow.

[0032] Simultaneously, when the inner pillar 3 in the middle of the front cover 2 connects to the connection port where the housing 6 in this embodiment is installed, the oblique opening of the inner pillar 3 slowly enters the interior of the connection port, and the outer side of the inner pillar 3 gradually presses against the outer walls of the rear cover 4 and the crown spring 5, making the connection between the connection ports more secure and forming an internal extrusion structure. (Refer to...) Figures 4-5 It can be seen that the finished connector assembled from the external riveting and internal machine structure in this embodiment has a lower operating temperature than the comparative component when the same 350 amp current is applied. Similarly, when the comparative component and the finished product are in the same ambient temperature of 30 degrees Celsius or 45 degrees Celsius, the maximum current passed through the finished product is also greater than that of the comparative component. Therefore, according to the experimental results in the table, the finished product in this embodiment adopts an external riveting and internal machine structure to allow the crown spring 5 to fully contact the inner wall of the housing 6, making the high current transmission more stable and the temperature rise lower. At the same time, the manufacturing process is simple and saves costs.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
