This arrangement allows the second elastic piece 241 and the fourth elastic piece 242 to hold each other in place, preventing deformation; and their strokes are consistent. When the second elastic piece 241 and the fourth elastic piece 242 are inserted into the mating cavity 810 of the mating conductive terminal 8, contact performance can be achieved simultaneously, with a shorter insertion stroke. Please refer to... Figure 10 as well as Figure 11 As shown in the illustrated embodiment of the present invention, the first arcuate surface and the second arcuate surface have opposite convex directions along the first direction A1-A1.

[0081] In the embodiment illustrated in the present invention, the second spring 241 and the fourth spring 242 are manufactured by tearing material.

The third sidewall 33 and the fourth sidewall 34 are provided with a first retaining spring 330 and a second retaining spring 340 protruding away from the receiving space 30. Both the first retaining spring 330 and the second retaining spring 340 are locked to the insulating body 1. The third sidewall 33 is provided with a first fixing block 331, a second fixing block 332 spaced apart from the first fixing block 331, and a first channel 333 located between the first fixing block 331 and the second fixing block 332. The fourth sidewall 34 is provided with a third fixing block 341, a fourth fixing block 342 spaced apart from the third fixing block 341, and a second channel 343 located between the third fixing block 341 and the fourth fixing block 342. In the embodiment illustrated in the present invention, the first fixing block 331 and the second fixing block 332 are simply supported beams stamped from the third sidewall 33 into the receiving space 30. The third fixing block 341 and the fourth fixing block 342 are simply supported beams stamped from the fourth sidewall 34 into the receiving space 30. This configuration facilitates manufacturing and improves the structural strength of the first fixing block 331, the second fixing block 332, the third fixing block 341, and the fourth fixing block 342, thereby making it easier to clamp the first fixing part 21 and the second fixing part 23 of the conductive terminal 2.
[0084] When the conductive terminal 2 is assembled into the retaining terminal 3, the conductive terminal 2 is inserted into the receiving space 30. The first spring piece 221 and the third spring piece 222 pass through the first channel 333, and the first fixing block 331 and the second fixing block 332 both abut against the first fixing part 21. At the same time, the second spring piece 241 and the fourth spring piece 242 pass through the second channel 343, and the third fixing block 341 and the fourth fixing block 342 both abut against the second fixing part 23. When the conductive terminal 2 is installed in place, the first mating part 22 and the second mating part 24 protrude from the receiving space 30. The first locking arm 311 and the second locking arm 321 are respectively engaged in the upper locking groove and the lower locking groove. The first limiting protrusion 213 and the second limiting protrusion 214 abut against the first side wall 31 and the second side wall 32 to prevent the conductive terminal 2 from being over-installed in the retaining terminal 3.
[0085] Please combine Figure 19 as well as Figure 20 As shown, after installation, the first fixing part 21 is adjacent to and spaced apart from the third sidewall 33. The electrical connector 100 includes a first heat dissipation channel 401 located between the first fixing part 21 and the third sidewall 33. The second fixing part 23 is adjacent to and spaced apart from the fourth sidewall 34. The electrical connector 100 includes a second heat dissipation channel 402 located between the second fixing part 23 and the fourth sidewall 34. The first heat dissipation channel 401 and the second heat dissipation channel 402 are used to allow air circulation, thereby facilitating the dissipation of heat generated during power transmission and improving safety.
[0086] Please combine Figures 14 to 17As shown, when the conductive terminal 2 is mated with the mating conductive terminal 8, the first mating portion 22 and the second mating portion 24 of the conductive terminal 2 are at least partially inserted into the mating cavity 810. The two ends (e.g., the upper and lower ends) of the first mating portion 22 and the second mating portion 24 are respectively abutted against the first connecting wall 813 and the second connecting wall 814. That is, the first connecting wall 813 and the second connecting wall 814 serve to position the first mating portion 22 and the second mating portion 24. When the conductive terminal 2 is inserted into place, the first abutting protrusion 8111 abuts against the portion of the first mating portion 22 located on both sides of the first spring piece 221 and the third spring piece 222, and the second abutting protrusion 8121 abuts against the portion of the second mating portion 24 located on both sides of the second spring piece 241 and the fourth spring piece 242. The first spring piece 221 and the third spring piece 222 abut against the inner side of the first contact wall 811, and the second spring piece 241 and the fourth spring piece 242 abut against the inner side of the second contact wall 812. With this configuration, the first docking part 22 and the second docking part 24 are precisely positioned in four directions: up, down, left, and right. This reduces the potential shaking that may occur when the conductive terminal 2 and the docking conductive terminal 8 are docked, thereby improving the reliability of the docking.
[0087] Compared to the prior art, the first docking portion 22 of the present invention is provided with a first spring piece 221, the first spring piece 221 including a first elastic contact portion 2211 protruding from the first fixing portion 21 along the first direction A1-A1; the second docking portion 24 is provided with a second spring piece 241, the second spring piece 241 including a second elastic contact portion 2411 protruding from the second fixing portion 23 along the first direction A1-A1; the first elastic contact portion 2211 extends along a first arcuate surface, the second elastic contact portion 2411 extends along a second arcuate surface, the first arcuate surface and the second arcuate surface protruding in opposite directions along the first direction A1-A1; thereby realizing the provision of elastic contact portions on the docking portion, thereby omitting the adapter spring, and improving structural reliability and safety.
