Each of the abutting faces 321 is provided with a recessed portion 322 which is recessed inwardly, that is, each abutting face 321 is provided The recessed portion 322 that is recessed toward the other abutting surface 321 is located at an intermediate position of the abutting surface 321 in the left-right direction and extends forward through the front end surface 323 of the abutting portion 32. The arrangement of the recessed portion 322 greatly reduces the contact or friction area of the mating surface 321 and the mating terminal of the mating connector, thereby greatly reducing the insertion and extraction force when the electrical connector 1 is mated with the mating connector. The left and right sides of the abutting portion 32 are adjacent to the base portion 31 and further provided with a pair of inwardly recessed notches 324 for snapping on the side walls of the two sides of the electronic device housing.

Referring to the third to fifth figures, each of the terminal modules 4 includes a row of conductive terminals 41 and an insulating block 42 that is formed on the conductive terminals 41, thereby better fixing the row of conductive terminals 41 together. The terminal module 4 is provided with an injection hole 420 for injection molding. The insulating block 42 is formed of a plastic material and has a dovetail groove structure on both sides of the longitudinal direction for reinforcing the outer casing 3 during injection molding.
