[0026] 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.

[0027] like Figures 1-4 As shown, a crown spring terminal includes a cylindrical terminal base 1 with a notch, a plurality of long through holes 11 are formed between the terminal base 1, and a plurality of connecting parts 12 are twisted between the long through holes 11. A terminal contact part 121 is formed at one end of the connecting part 12 and is arranged inside the terminal base 1, and a terminal fixing part 122 is formed at the other end and is arranged outside the terminal base 1. A terminal contact part 121 and a terminal fixing part 122 are formed at one end of each of the connecting parts 1. The terminal structure of this scheme adopts a twisted ring arrangement, which can greatly improve the connection stability when the user plugs it in and use it, and the effect of conducting current is better.

[0028] like Figure 2 As shown, the plurality of long through holes 11 formed between the terminal bases 1 of this solution are arranged in an aligned manner at intervals. This solution can select an aligned arrangement structure according to user needs to improve the stability and conductivity of the connection.

[0029] Not shown in the figure, as a preferred structure, the plurality of elongated through holes 11 formed between the terminal bases 1 of this scheme are arranged in an intermittent staggered arrangement. Compared with the above-mentioned aligned arrangement structure, the structure in which the elongated through holes 11 are arranged in an intermittent staggered arrangement can greatly improve the stability and conductivity of the connection.

[0030] Furthermore, in this solution, the area of the terminal contact portion 121 is larger than that of the terminal fixing portion 122. Since the contact surface of the contact portion 121 is increased, the current conduction effect can be greatly improved; secondly, the service life is also enhanced.

[0031] In this solution, the terminal contact portion 121 is a bent contact spring, and the terminal fixing portion 122 is a bent fixed spring and a bent elastic spring. Furthermore, in this solution, the terminal contact portion 121 is a bent contact spring, and the terminal fixing portion 122 is composed of two bent fixed springs. The two fixed springs and the contact spring are staggered, which can generate a balanced force distribution when the user plugs and unplugs, thereby greatly improving the plug-in stability and service life.

[0032] like Figure 1 As shown, the terminal base 1 of this solution is a multi-section structure. Specifically, the terminal base 1 is a two-section structure, which can adapt to longer-sized connectors.

[0033] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
