[0028] Example

[0029] like Figure 1As shown, an embodiment of the utility model provides a connection structure based on welding connection, which is used to realize the connection of two bodies 100 to be connected, including a conical hole 110 arranged at the end of one of the bodies 100 to be connected, and a cone 120 arranged at the end of the other body 100 to be connected; wherein the conical hole 110 and the cone 120 are nested and matched, and the inner wall of the conical hole 110 is welded to the outer wall of the cone 120.

[0030] In the present solution, the connection structure is used to realize the connection of two bodies 100 to be connected, wherein a tapered hole 110 is provided at the end of one of the bodies 100 to be connected, wherein a cone 120 is provided at the end of the other body 100 to be connected, the cone 120 is nested and matched with the tapered hole 110, and the inner wall of the tapered hole 110 is welded to the outer wall of the cone 120. Through the structural design of the connection structure, compared with the groove welding connection method conventionally used in the prior art, the hole-axis matching structure has a better bending resistance of the weld; and compared with the plane welding connection method, a larger welding area can be provided to increase the bearing capacity of the weld, thereby ensuring the stability of the connection structure.

[0031] In some embodiments, the cone angle of the cone 120 is α, where α satisfies 0°≤α<36°.

[0032] Among them, those skilled in the art should know that the cone angle is the angle between two generatrixes of the axial section of the cone, specifically as follows: Figure 1 shown.

[0033] Furthermore, the cone angle of the tapered hole 110 is β, wherein β satisfies 0°≤β<36°.

[0034] In this solution, by designing the angles of the cone 120 and the tapered hole 110, and the angles of the two are not necessarily equal, there may be certain differences, but it should be noted that the specific angle design should satisfy the requirement that the tapered hole 110 can be nested and matched with the cone 120.

[0035] Specifically, through angle design, the amount of solder remaining between the mating surfaces can be controlled by adjusting the mating angle between the tapered hole 110 and the cone 120, thereby fine-tuning the solder joint performance.

[0036] The cone angles of the cone hole 110 and the cone body 120 are both less than 36°. Specifically, by limiting the maximum cone angle, the adverse effect of the increase in the welding point material on the axial component can be effectively reduced, thereby ensuring the welding quality.

[0037] In some embodiments, the major axis length of the cross section of the object to be connected 100 is less than 0.6 mm.

[0038] The major axis length of the cross section of the object to be connected 100 is less than 0.6 mm. Specifically, the shape of the cross section of the object to be connected 100 includes but is not limited to a circle, an ellipse, a polygon, and the like.

[0039] like Figure 2 As shown, in some embodiments, the cone 120 is a frustum structure.

[0040] The tapered hole 110 is also a frustum structure. By adopting the frustum structure design, the fitting depth of the two can be easily adjusted, thereby achieving the adjustment of the welding fitting surface range.

[0041] like Figure 3 As shown, further, as another way to adjust the fitting range of the welding surface, a threaded hole 121 is provided at the end of the cone 120, and the threaded hole 121 is provided with a nut structure 210 that cooperates with the thread, and the range of the welding fitting surface can be adjusted by adjusting the fitting length between the nut structure 210 and the threaded structure.

[0042] In some embodiments, one end of the frustum structure close to the end of the object 100 to be connected is a large round end, and the other end is a small round end, wherein the diameter of the large round end is greater than the diameter of the small round end.

[0043] Furthermore, the diameter D of the large circular end satisfies: 0.1mm≤D≤0.6mm.

[0044] Furthermore, the diameter d of the small round end satisfies: 0.1mm≤d<0.6mm.

[0045] Specifically, by designing the size, the bending flexibility of the solder joint can be improved within this range, and by adjusting the matching size, the stiffness of the solder joint can be adjusted to meet the requirements of different working environments.

[0046] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
