In its free state, the fourth abutment spring arm 24212 includes a fourth abutment portion 24213 that protrudes from the fourth base 2421 along its thickness direction.

[0127] Please compare Figures 20 to 22 The first metal spring 212 has three embodiments, which will be understood by those skilled in the art. In the first embodiment of the present invention, there is one fourth abutment spring arm 24212 corresponding to one fourth opening 24211. In the second embodiment of the present invention, there are two fourth abutment spring arms 24212 corresponding to one fourth opening 24211, and the movable ends of the two fourth abutment spring arms 24212 are separated from each other. In the third embodiment of the present invention, there are two fourth abutment spring arms 24212 corresponding to one fourth opening 24211, and the fourth base 2421 is provided with a fourth connecting portion 24214 that connects the movable ends of the two fourth abutment spring arms 24212 together.

[0128] Please compare Figure 23 as well as Figure 24 In one embodiment of the invention, the movable end of the fourth abutment spring arm 24212 abuts against the fourth inner surface 2411a of the fourth metal plate 241 in a free state, meaning the fourth abutment spring arm 24212 is a simply supported beam. Those skilled in the art will understand that designing the fourth abutment spring arm 24212 as a simply supported beam increases the insertion and extraction force of the second electrical connector 200, improves docking reliability, and effectively reduces resonance problems.

[0129] In another embodiment of the present invention, in the free state, the movable end of the fourth abutment spring arm 24212 does not abut against the fourth inner surface 2411a of the fourth metal plate 241, that is, the fourth abutment spring arm 24212 is a cantilever beam. Those skilled in the art will understand that designing the fourth abutment spring arm 24212 as a cantilever beam helps reduce the insertion and extraction force of the second electrical connector 200, thereby facilitating insertion of the second electrical connector 200. When the second electrical connector 200 is inserted, the fourth abutment portion 24213 of the fourth abutment spring arm 24212 is compressed by the second electrical connector 200 and undergoes elastic deformation. At this time, the movable end of the fourth abutment spring arm 24212 abuts against the fourth inner surface 2411a of the fourth metal plate 241, forming a simply supported beam shape, thereby reducing resonance problems.
