when the signal terminal 20 and the insulating base 10 are mounted, the signal terminal 20 is inserted into the first through groove 11, the connecting portion 21 and the insertion plate portion 22 protrude from two sides of the insulating base 10, and the fixing portion 23 is completely embedded into the first through groove 11 and is in interference fit with an inner wall of the insulating base 10, which is used for forming the first through groove 11.

When the signal shielding structure 200 is assembled with the insulating base 10 in an inserting manner, the plurality of shielding bodies 30 may be sequentially inserted into the insulating base 10, so that the first shielding plate 31 and the second shielding plate 32 pass through the second through groove 12, the first extending plate 33 and the second extending plate 34 are respectively embedded into the first groove 13 and the second groove 14, the first clamping block 321 is embedded into the first clamping groove 331 adjacent to the shielding body 30, the second clamping block 341 is embedded into the second clamping groove 311 adjacent to the signal shielding, the plurality of shielding bodies 30 are inserted into the insulating base 10, and the signal shielding structure 200 is assembled with the insulating base 10 in an inserting manner.

When the two electrical connectors 100 are connected, the connecting portion 21 of the male end is connected with the connecting portion 21 of the female end, and an electrical signal is transmitted from the male end to the female end through the signal terminal 20, and enters the electronic device connected with the female end through the female end.

In the process of electrical signal transmission, the first shielding plate 31 of the male end, the second shielding plate 32 and the first shielding plate 31 of the female end, the second shielding plate 32 are connected, the plug connector of the male end is connected with the motherboard after power is obtained, the current is transmitted to the female end from the male end, the plug connector of the female end is electrically connected with the grounding end of the motherboard, the flow of the current on the shielding body 30 is realized, and then the signal terminal 20 located in the accommodating space 50 is shielded from the external interference signal and the crosstalk signal.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
