When the mating body 212 of the insulating base 21 is inserted downward into the mating space 112 of the insulating base 11, the protrusions 2121 at the left and right sides of the mating body 212 must be aligned with the recesses 1121 at the left and right sides of the mating space 112 to be combined with each other in an inserting manner, so as to have a foolproof effect, and further avoid the occurrence of damage caused by inserting the plurality of first terminals 12 of the receptacle connector 1 and the plurality of second terminals 22 of the plug connector 2 in wrong directions.

The first housing 13 of the receptacle connector 1 and the second housing 23 of the plug connector 2 can be made of metal materials, so that when the plurality of first terminals 12 and the plurality of second terminals 22 perform an electronic signal transmission operation, the first housing 13 and the second housing 23 made of metal materials can have a shielding function, thereby reducing noise and crosstalk.

Sixth, the second mating portion 123 of the first terminals 12 has two first clamping arms 1231, and the fourth mating portion 223 of the second terminals 22 has two second clamping arms 2231, so that when the first electrical connector 3 and the second electrical connector 4 are inserted into the socket connector 1 and the plug connector 2, the two first clamping arms 1231 and the two second clamping arms 2231 can form a bidirectional contact, so that the first electrical connector 3 and the second electrical connector 4 can be inserted into an electrical contact without distinguishing the front and the back, thereby improving the convenience of use.
