[0020] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0021] As Figures 1-4 Shown, a kind of outgoing line PIN adapter injection molded part and the welding structure of wiring board assembly, including adapter assembly 1 and wiring board assembly 2, adapter assembly 1 is installed on the upper end of wiring board assembly 2, wiring board assembly 2 includes support base 21, support base 21 is provided with three groups of three-item wiring board 23, three-item wiring board 23 upper end includes lead-out end 233, adapter assembly 1 includes outgoing line PIN 11, outgoing line PIN 11 lower end is fixed with rivet point 13, outgoing line PIN 11 lower end rivet point 13 is connected with lead-out end 233, outgoing line PIN 11 lower end rivet point 13 is connected with lead-out end 233 using resistance welding;

[0022] In use, the outgoing PIN 11 is electrically resistance welded to the adapter injection molding 12 through its rivet point 13 and the lead-out end 233 of the terminal block assembly 2, ensuring a firm connection while overcoming the problem of the outgoing PIN 11 being slender and prone to bending, improving the accuracy of position control and reducing assembly difficulties.

[0023] The outgoing PIN 11 has an adapter injection molding 12 fixed to its outer side. The main function of the outgoing PIN 11 is to serve as a conductor for the three-phase motor winding to be led out to the outside of the motor, realizing the transmission of electric energy. The adapter injection molding 12 provides stable support and protection for the outgoing PIN 11, enhancing the mechanical strength of the outgoing PIN 11 and preventing it from being easily bent or damaged due to its slender shape.

[0024] The outer side of each of the three three-item terminal blocks 23 is sprayed with an insulating coating 231. The insulating coating 231 ensures that the terminal block assembly 2 will not cause safety hazards due to current leakage or short circuit during operation, and protects the terminal block from environmental factors such as moisture and corrosion, thereby improving the safety and reliability of the entire assembly.

[0025] The lower end of each of the three three-item terminal blocks 23 is provided with a plurality of wire end grooves 232. The wire end grooves 232 have a U-shaped cross-section. Through the U-shaped wire end grooves 232, the winding lead-out wires can be securely clamped therein, preventing the lead-out wires from shaking or falling off and ensuring the stability of the connection.

[0026] The outer side of the support base 21 is fixed with a plurality of fixed legs 22. The fixed legs 22 ensure that the terminal block assembly 2 can be stably installed at the desired position, while providing sufficient mechanical strength to prevent the terminal block assembly 2 from shifting or loosening during motor operation or assembly.

[0027] The outgoing PIN 11 and the adapter injection molding 12 on the outer side are integrally injection molded. Through integral injection molding, the positional accuracy of the outgoing PIN 11 is ensured, and the assembly difficulty when assembling with the counterpart is reduced.

[0028] The specific implementation of the embodiment is that, when the welding structure of the out-line PIN adapter injection molding part and the wiring board assembly is used, first, the out-line PIN 11 is used as a conductor for leading out three phases of motor windings to the outside of the motor, and a rivet point 13 is fixed at the lower end of the out-line PIN 11 for connecting with the leading-out end 233 of the wiring board assembly 2, the adapter injection molding part 12 provides stable support and protection for the out-line PIN 11, enhances the mechanical strength of the out-line PIN 11, and reduces the problem of easy bending due to the elongated shape, and in the welding process, the side of the out-line PIN 11 adapter injection molding part 12 with the rivet point 13 is attached to the PIN end of the wiring board assembly 2 and connected by resistance welding, and the welding method ensures that the connection between the out-line PIN 11 adapter injection molding part 12 and the wiring board assembly 2 is firm and reliable, and improves the strength and stability of the connection.

[0029] Specifically, by adopting the new out-line PIN 11 adapter injection molding part 12 and segmentally welding the side with the rivet point 13 to the PIN end of the wiring board assembly 2, this method effectively solves the problem that the out-line PIN 11 injection molding part is easy to bend due to the elongated shape, leading to difficult position degree control and assembly difficulty in the prior art, and meanwhile reduces the use of injection molding material, thereby reducing the cost.
