(2) Because the mating terminal 50 is provided with the contact portion 51 extending downward and the connection portion 52 extending from the contact portion 51 in a backward bending manner, when the electrical connector 100 and the mating connector 400 are mated and plugged, the connection portion 52 is easy to contact with the metal shell 30 to cause a short circuit, the top surface of the second plate portion 332 is designed to be lower than the top surface of the first plate portion 331, the top surfaces of the second plate portions 332 are positioned under the connection portions 52 of the plurality of mating terminals 50, and a gap is formed between the top surfaces of the second plate portions 332 and the bottom surfaces of the connection portions 52, so that the occurrence of the short circuit caused by the contact of the metal shell 30 with the connection portions 52 can be avoided.

(3) Compared with the design that the top surface of the metal shell 30 is flush with the top surface of the insulating body 10, the design that the top surfaces of the first side wall 33, the second side wall 34 and the second end wall 32 are lower than the abutting surface 11 of the insulating body 10 can avoid that the top surface of the metal shell 30 is higher than the abutting surface 11 of the insulating body 10 due to the process error, so that the situation that the top surface of the metal shell 30 abuts against the abutting connector 400 and the abutting surface 11 of the insulating body 10 does not abut against the abutting connector 400 is caused, the stability of the abutting of the electric connector 100 and the abutting connector 400 is further prevented from being influenced, the electric connection stability of the conductive terminals 20 and the abutting terminals 50 is ensured, meanwhile, the precision requirement on the metal shell 30 can be reduced, and the product yield is improved; because the height of the insulating body 10 and the metal housing 30 is limited in order to realize a low-height design of the electrical connector 100 and the mating connector 400, the first end wall 13, the second end wall 32, a portion of the second side wall 34, and the first plate 331 together enclose the accommodating space 35, the accommodating space 35 is used for accommodating the protruding plate 45 of the mating connector 400, and the top surface of the second end wall 32, the top surface of the first side wall 33, and the top surface of the first plate 331 are higher than the top surface of the second plate 332, so that the guiding and limiting effects of the accommodating space 35 on the protruding plate 45 can be better realized, and the problem that the protruding plate 45 is easy to deflect or loose due to lower limiting height in the accommodating space 35 is avoided.

(4) Compared with the design that the top surface of the second end wall 32 and the top surface of the second side wall 34 are higher than the top surface of the first plate 331 in the up-down direction, the design that the top surface of the second end wall 32 and the top surface of the second side wall 34 are flush with the top surface of the first plate 331 in the up-down direction is beneficial to that when the butt connector 400 swings left and right after being matched and plugged with the electric connector 100, the second end wall 32, the second side wall 34 and the first plate 331 can jointly contact the shell 40 of the butt connector 400, so that the shell 40 continues to incline from the second side wall 34 to the first side wall 33 due to the fact that the first plate 331 fails to contact the shell 40, and the butt connector 400 is further prevented from being abutted against the electric connector 100 and being unstable; because the first plate 331 contacts the housing 40 of the mating connector 400 when the mating connector 400 is mated with the electrical connector 100 and swings left and right, the width of the second plate 332 along the left and right directions is designed to be greater than the distance between the left edge of the leftmost connecting portion 52 and the right edge of the rightmost connecting portion 52 of a row of the mating terminals 50, so that the contact between the mating terminals 50 and the first side wall 33 can be avoided to cause a short circuit.
