That is, in some embodiments of this utility model, these practical details are not essential.

[0031] Example 1

[0032] like Figures 1-5 As shown, Figure 1 This is a three-dimensional structural diagram of the crown spring structure; Figure 2 This is a front view of the crown spring structure; Figure 3 A three-dimensional schematic diagram of the crown spring structure in its unfolded state; Figure 4 This is a front view of the crown spring structure in its unfolded state; Figure 5 This is a side view of the crown spring structure in its unfolded state. The crown spring structure in this embodiment includes a first spring ring 1, a second spring ring 2, and multiple spaced spring strips 3. One end of each spring strip 3 is connected to the first spring ring 1, and the other end of each spring strip 3 is connected to the second spring ring 2; that is, the spring strips 3 are located between the first spring ring 1 and the second spring ring 2. It can be understood that the first spring ring 1 and the second spring ring 2 are ring-shaped structures, i.e., they have hollow portions, and after the multiple spring strips 3 are connected to the first spring ring 1 and the second spring ring 2, their entirety also forms a ring-shaped structure.

[0033] In practical applications, after the spring bar 3 is connected to the first spring ring 1 or the second spring ring 2, there is an included angle 4. The existence of this included angle 4 determines the tilt angle of the spring bar 3 relative to the first spring ring 1 or the second spring ring 2. In this embodiment, the included angle 4 between the spring bar 3 and the first spring ring 1 or the second spring ring 2 is an acute angle, that is, the spring bar 3 is tilted relative to the first spring ring 1 or the second spring ring 2.

[0034] Specifically, the spring bar 3 has a first outer convex area 31 and an inner concave area 32, the first outer convex area 31 is located at the end position of the spring bar 3, and the inner concave area 32 is located at the middle position of the spring bar 3, wherein the first outer convex area 31 is opened in the direction away from the center of the crown spring structure, and the inner concave area 32 is opened in the direction close to the center of the crown spring structure, that is, the opening direction of the first outer convex area 31 is opposite to that of the inner concave area 32. Further, the spring bar 3 also has a second outer convex area 33, which is arranged at the end of the spring bar 3 away from the first outer convex area 31, and the first outer convex area 31 and the second outer convex area 33 have the same opening form, and the arrangement of the first outer convex area 31 and the second outer convex area 33 is beneficial to improve the number of contact points of the crown spring structure and other components.

[0035] Further explanation, review Figures 3-5 The crown spring structure is formed by a stamping process in the initial stage, and the sheet structure has the first outer convex area 31, the inner concave area 32 and the second outer convex area 33, and only needs to be wound to close the two ends to form the crown spring structure, so since the inner concave area 32 is formed in the sheet structure, it is not necessary to twist it later, and the side of the inner concave area 32 facing the center is a flat surface, which directly abuts the plug pin in later use. It should be noted that the "flat surface" refers to the side of the spring bar 3 facing the center line directly abutting the plug pin, and the edge of the side does not abut the plug pin, thereby avoiding the phenomenon that the edge of the side rubs the plug pin and damages the plug pin, greatly improving the problem of the plug pin. In addition, the sheet structure formed by the stamping process is beneficial to greatly reduce the production cost.

[0036] Specifically, the first spring ring 1, the second spring ring 2 and the spring bar 3 are made of high-conductivity and high-yield strength materials, such as spring materials.

[0037] In summary, through the cooperation of the first spring ring 1, the second spring ring 2 and the spring bar 3, when in use, the plug pin is inserted into the crown spring structure, the arrangement of the inner concave area 32 increases the number of contact points between the plug pin and the crown spring structure, the arrangement of the first outer convex area 31 increases the number of contact points between the crown spring structure and the external conductive component, and at the same time, it also increases the normal force between the first outer convex area 31 and the plug pin, which is beneficial to reduce the resistance and solve the problem of temperature rise. In combination with the increase of the number of contact points, the reliability and current carrying capacity of the crown spring structure are further improved.

[0038] Example two

[0039] As Figure 6 and Figure 7As shown, the difference between the crown spring structure of the embodiment and the embodiment one is that the included angle 4 of the embodiment is a right angle, that is, the spring bar 3 and the first spring ring 1 and the second spring ring 2 are perpendicular to each other. The rest of the structure is the same as that in the embodiment one, which will not be repeated here, and please refer to the embodiment one above.
