A surface of a front end of the elastic arm 114 away from the middle partitioning board 1112 is provided with a notch which forms a front limiting portion 1141.
In the preferred embodiment, in the six mating posts 113 of the upper row, a first prevent mis-insertion protruding rib 115 protrudes upwardly from each of the mating post 113 positioned at the leftmost and the mating post 113 positioned at the rightmost. The first prevent mis-insertion protruding rib 115 substantially is a hollow rectangular door-shaped structure, a slot 1152 is formed at a position where the first prevent mis-insertion protruding rib 115 is connected with the mating post 113, and the slot 1152 is communicated with the first terminal receiving cavity 1131, the slot 1152 forms a notch on a front surface of the mating post 113, so that the slot 1152 and the first terminal receiving cavity 1131 together constitute an opening, which is substantially inversed T-shaped, at the front surface of the mating post 113. During injection molding of the first connector housing 11, the slot 1152 may attain an effect to maintain a wall thickness of the first connector housing 11 uniform so as to prevent improper deformation of the first connector housing 11 from occurring and save material. The first prevent mis-insertion protruding rib 115 protrudes upwardly from a middle portion of an upper surface of the mating post 113, an outer contour of the first prevent mis-insertion protruding rib 115 is elongated, and a width of the first prevent mis-insertion protruding rib 115 is smaller than a width of the mating post 113, a combination of the first prevent mis-insertion protruding rib 115 and the mating post 113 forms a structure having an outer contour which is substantially inversed T-shaped.

A width of the second prevent mis-insertion protruding rib 116 is smaller than a width of the mating post 113.
The first prevent mis-insertion protruding ribs 115 and the second prevent mis-insertion protruding rib 116 associated with the corresponding mating posts 113 cooperate with each other to form a set of a prevent mis-insertion assembly which only allows the first electrical connector 1 having the prevent mis-insertion assembly to be correctly mated a with the second electrical connector 2 having a corresponding prevent mis-insertion assembly.
In practical application, with respect to a plurality of first electrical connectors 1 which have similar outer profiles but realize different electrical functions, the plurality of first electrical connectors 1 may be distinguished by being provided with different prevent mis-insertion assemblies. Here, “similar outer profiles” may be understood that they are the same in the number of the mating posts 113 and they are similar in an arrangement manner of the plurality of mating posts 113.

Because the first prevent mis-insertion protruding rib 115 and the second prevent mis-insertion protruding rib 116 are provided on the different mating posts 113, any two electrical connectors having different prevent mis-insertion assemblies cannot mate with each other, so that mis-insertion may be prevented from occurring.
With respect to a case that the plurality of mating posts 113 are provided as the upper row and the lower row in the preferred embodiment, preferably, the first prevent mis-insertion protruding rib 115 and the second prevent mis-insertion protruding rib 116 provided to the mating posts 113 in the upper row each protrude upwardly from the upper surface of the corresponding mating post 113, the first prevent mis-insertion protruding rib 115 and the second prevent mis-insertion protruding rib 116 provided to the mating posts 113 in the lower row each protrude downwardly from the lower surface of the corresponding mating post 113.
