The insertion space 11 forms an outward opening 111, and the bottom wall 12 is provided with a plurality of terminal slots. 121. The terminal 2 is received, and the two side walls 13 are formed, and one of the side walls 13 forms a receiving slot 131 to communicate with the insertion space 11. In this embodiment, the two side walls 13 respectively form two receiving slots 131 to communicate with the insertion space 11 .

In this embodiment, the network electrical connector M having the foolproof structure further includes a metal shielding shell 3 covering the insulating housing 1. The metal shield case 3 has a housing opening 31 corresponding to the opening 111.

In this embodiment, the network electrical connector M having the foolproof structure is provided with two anti-scratch elastic pieces 4 and two transfer elastic pieces 5 to form the foolproof structure of the present invention.

Each of the foolproof elastic pieces 4 is fixed to the side wall 13 and extends into the receiving groove 131. The accommodation groove 131 is a space that can be contracted when the weatherproof elastic piece 4 is elastically deformed. The anti-snaking elastic piece 4 has a fixing portion 44, a resilient arm 41, a pair of connecting portions 42 and a stopping portion 43. The fixing portion 44 is fixed in the side wall 13. The elastic arm 41 extends from the fixing portion 44 to the In the receiving groove 131, the abutting portion 42 extends from one end of the elastic arm 41. The stopping portion 43 is bent and extended by the abutting portion 42 and extends into the insertion space 11.
