In this embodiment, the first contact portion 21 is positioned inside the first plug-in portion 12 after assembly to meet the plug-in conduction requirements. The first wiring portion 22 is connected to the first wire 30 by riveting, and of course it is not excluded that the first wiring portion 22 is connected to the first wire 30 by welding or piercing, and there is no limitation here, as long as the connection is conductive. A first stopper 231 and a first stopper 232 are provided on the first fixing portion 23; the first stopper 231 and the first step 111 preset in the first terminal hole 11 support the top, limiting the depth of the first terminal 2 implanted in the first terminal hole 11, and the first stopper 232 is engaged with the first spring piece 112 preset in the first terminal hole 11 after the first terminal 2 is implanted in place, limiting the first terminal 2 from exiting the first terminal hole 11.

[0025] The female connector 20 has a second insulating seat 3 and a second terminal 4. The second insulating seat 3 is made of plastic injection molding. The second terminal 4 is implanted in a second terminal hole 31 preset in the second insulating seat 3. The second insulating seat 3 has a second plug-in portion 32 and a second buckle portion 33. The second plug-in portion 32 is a socket that matches the first plug-in portion 12 for insertion and connection. A portion of the second terminal hole 31 overlaps with the second plug-in portion 32. The second terminal 4 is a hardware part made by stamping. The second terminal 4 has a second contact portion 41 at the front end, a second wiring portion 42 at the rear end, and a second fixing portion 43 located between the second contact portion and the second wiring portion. In this embodiment, the second contact portion 41 protrudes into the second plug-in portion 32 after assembly is completed so as to meet the plug-in connection requirements with the first contact portion 21 of the first terminal 2, such as Figure 5 As shown. The second wiring portion 42 is connected to the second wire 40 by riveting. Of course, it is not excluded that the second wiring portion 42 is connected to the second wire 40 by welding or piercing. There is no limitation here, as long as the connection is conductive. A second stop portion 431 and a second stop portion 432 are provided on the second fixing portion 43; the second stop portion 431 is supported by the second step 311 preset in the second terminal hole 31 to limit the depth of the second terminal 4 implanted in the second terminal hole 31, and the second stop portion 432 is engaged with the second spring piece 312 preset in the second terminal hole 31 after the second terminal 4 is implanted in place, limiting the second terminal 4 from withdrawing from the second terminal hole 31.

[0026] Similarly, if Figure 3 , 5 As shown, in the present embodiment, the second stop portion 431 is a leg standing on the second fixing portion 43, and is symmetrically arranged according to the implantation direction; the second stop portion 432 is a recessed notch on the second fixing portion 43, and the second spring piece 312 is a plastic piece extending from the inside of the second insulating seat 3 into the second terminal hole 31, and the second spring piece 312 extends obliquely toward the implantation direction; in the process of implanting the second terminal 4 into the second terminal hole 31 from back to front, the second spring piece 312 is first pressed and avoided, and when the second terminal 4 is implanted in place, the second spring piece 312 automatically pops out and forms a snap connection with the second stop portion 432, limiting the second terminal 4 from withdrawing from the second terminal hole 31, with a simple structure, convenient manufacturing and assembly, and stable and reliable assembly.
