[0029] The present application provides a soldering type PCBA connection terminal, such as Figure 1As shown, it includes a connecting terminal body 1 and a supporting component 13; wherein, a bending portion 12 is provided on the connecting terminal body 1 for buffering the bending force applied to the connecting terminal body 1 during welding; a supporting component 13 is provided at the bottom of the connecting terminal body 1 for preventing the connecting terminal body 1 from tilting when placed.

[0030] In this embodiment, the connecting terminal body 1 is subject to bending forces from the welding tool during welding, which can easily cause structural deformation and misalignment of the connecting terminal body 1 during welding, reducing the stability of the connecting terminal body 1 during electrical connection. Therefore, in this embodiment, a bent portion 12 is provided in the middle of the connecting terminal body 1 to effectively disperse the bending forces from the welding tool. Furthermore, a support assembly 13 is provided on the connecting terminal body 1 to maintain stability during welding and reduce the stress on the pad 4.

[0031] In some embodiments, a connection assembly 11 is provided on the connection terminal body 1 to facilitate positioning and connection when the connection terminal body 1 is welded.

[0032] In this embodiment, the connecting component 11 can be a welding contact with a protrusion, which is used to weld the connecting terminal body 1 to the output terminal 2, so that the connecting terminal body 1 can be accurately positioned during the welding process, ensuring the accuracy of the welding position and improving the welding efficiency and reliability.

[0033] In some embodiments, the connecting terminal body 1 is provided with the auxiliary welding assembly 14 , and the auxiliary welding assembly 14 is connected to the supporting assembly 13 .

[0034] In this embodiment, the auxiliary soldering assembly 14 can be a metal soldering pin. The auxiliary soldering assembly 14 secures the connection terminal body 1 to the PCBA board 3 via soldering, further enhancing the soldering stability of the connection terminal body 1 and ensuring a secure connection. Furthermore, the auxiliary soldering assembly 14 is connected to the support assembly 13 to reduce stress generated by the auxiliary soldering assembly 14 during resistance welding.

[0035] In some embodiments, at least one supporting assembly 13 is provided on both sides of the bottom of the connecting terminal body 1 .

[0036] In this embodiment, if Figure 1 As shown, at least one supporting assembly 13 is provided on each of the two sides of the bottom of the connecting terminal body 1 , for maintaining the stability of the connecting terminal body 1 and preventing it from tilting during placement and welding.

[0037] In some embodiments, at least one connecting component 11 is provided on the connecting terminal body 1 .

[0038] In this embodiment, if Figure 1 As shown, when the sizes of the connection terminal body 1 and the output terminal 2 body become larger, a plurality of connection components 11 can be provided on the connection terminal body 1 to enhance the stability of welding.

[0039] In some embodiments, at least two auxiliary welding assemblies 14 are provided on the connection terminal body 1 .

[0040] In this embodiment, if Figure 1 As shown, the auxiliary welding assembly 14 is connected to the connecting assembly 11 and corresponds one to one.

The other end of the terminal is then welded to the output terminal 2 by resistance welding.

[0047] At the same time, the size of the connecting terminal body 1 depends on the size of the motor output current. When the motor requires a larger output current, the connecting terminal body 1 has a greater demand for the current passing capacity, which leads to a larger size of the connecting terminal body 1. Therefore, it is necessary to set up multiple supporting components 13 and multiple auxiliary welding components 14.

[0048] This application also proposes an electrical connection device, such as Figure 2 As shown, it includes an output terminal 2, a PCBA board 3 and a soldered PCBA connection terminal as described in the above embodiment; wherein, at least three connection terminal bodies 1 are provided on the PCBA board 3, and the number of the connection terminal bodies 1 corresponds to the number of the output terminals 2; the output terminal 2 is connected to the connection terminal body 1 through the connection component 11, and is connected to the motor for outputting current to the motor.
