[0002] Current electrical connector housings, especially power connector housings, do not have an anti-oblique insertion structure or a protective structure on the outside of the docking portion. For example, an electrical connector with publication number CN209217300U includes a plurality of conductive terminals, a base, and a retaining frame. The base has a plurality of terminal receiving grooves formed forward from the rear end surface of the base and accommodating the conductive terminals, and a locking structure formed on the top surface of the base. The retaining frame is arranged on the base, and the retaining frame has a transverse frame portion extending laterally, a plurality of positioning arms extending forward from the transverse frame portion downwardly and obliquely and respectively inserted into the terminal receiving grooves, and a locking plate portion extending forward from the top of the transverse frame portion to the top of the top surface of the base and having elasticity, the positioning arms positioning the conductive terminals along the slopes in the terminal receiving grooves, and the locking plate portion forming a locking structure that cooperates with the locking structure of the base to lock. It is easy to cause oblique insertion during the plugging and unplugging process, thereby damaging the conductive terminals of the electrical connector, and when the electrical connector is subjected to lateral force, the conductive terminals of the electrical connector will also be damaged.
