[0023] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 2 :

[0024] A quick-connect structure for motor terminal blocks, comprising a circuit board 2 located in a motor housing 1, a plurality of wires 3 being arranged on the circuit board 2 by welding, a plurality of terminal blocks 4 being fixed on the circuit board 2, the terminal blocks 4 comprising a wiring substrate 40 abutting against the circuit board 2, one side of the wiring substrate 40 extending upward and being formed with a longitudinally arranged plug-in terminal 41, the top of the plug-in terminal 41 being formed with a U-shaped interface 42 which is communicated from top to bottom and has an opening on one side.

[0025] In actual use, the wire will be welded to the circuit board 2, and one end of the wire 3 will be extended to connect to the terminal. During the connection process, one end of the wire is embedded in the U-shaped interface, and the wire does not need to be stripped. The U-shaped interface 42 is heated by the heat clamp, so that the enamel on the surface of the wire is heated and vaporized, thereby connecting the end to the terminal 4. The above method is more convenient to install, the wire connection is stable and not easy to be cold, which greatly improves product quality and production efficiency.

[0026] Preferably, the wiring substrate 40 is provided with a plurality of longitudinally arranged fixing plugs 43 , and the circuit board 2 is provided with fixing holes 20 corresponding to the fixing plugs 43 .

[0027] Furthermore, the wiring substrate 40 can achieve a stable fixed connection with the fixing hole 20 through the fixing plug 43 .

[0028] Preferably, the fixing plug 43 is integrally formed with the wiring substrate 40, and the fixing plug 43 is located at the outer edge of the wiring substrate. In fact, the fixing plug 43 is integrally stamped with the wiring substrate 40, and the fixing plug 43 is bent upward by bending.

[0029] Preferably, both ends of the top of the fixing plug 43 are rounded to facilitate insertion into the fixing plug hole 20 .

[0030] Preferably, the top of the plug terminal 41 extends upward to form a plug connector 44 , both ends of the top of the plug connector 44 are provided with chamfers, and the top of the U-shaped interface 42 is located at the lower end of the plug connector 44 .

[0031] In the above structure, the end of the wire can extend upward from a portion of the U-shaped interface 42 to prevent the wire from sliding off the bottom of the U-shaped interface; the extended portion may cause the copper wire in the wire to spread out and come into contact with adjacent wires, thereby forming a plug connector 44 to isolate the top thereof.

[0032] Preferably, the wiring substrate 40, the plug-in terminal 41 and the U-shaped interface 42 are integrally formed. The integrally formed method can improve the overall strength.
