The side of the circuit board 38 of the electrical connector includes a main body 40 and a spring arm 50, wherein: the main body 40 includes a vertical plate 41 and a horizontal plate 4 2 which are connected vertically, and one side of the vertical plate 4 1 It is integrally connected with one side of the horizontal plate 42, so it is a strong and stable angle frame. One end is connected and fixed to one side of the plastic base 35. The f end of the vertical plate 41 is bent toward the horizontal plate 42 to form a The second transverse plate 43 has a first stopper punched out to one side in order to be locked in the locking hole 39 on the side of the circuit board 38; a second stopper 46 is provided at the "front end" of the horizontal plate, and A grounding spring piece 48 is embossed on the surface of the plate, and the rear end is connected to a downwardly extending positioning surface 47. The spring arm 50 is bent upward from the horizontal plate 4 2 of the main body 40 in a vertical direction. The rear end 51 is connected to the horizontal plate 4 2 and the front end 5 2 is open. The front end is provided with a snap portion 53 and a toggle portion 54 of a snap circuit board 38. The upper end of the snap portion 53 is inclined and the lower end is In the horizontal plane, the lower edge of the front end 52 abuts on the second stopper 46 and is bent toward the vertical plate 41 to form a first transverse plate 56. The direction plate 56 is located below the second transverse plate 43 of the main body 40 and one side thereof is stopped by the second broadcast block 4 6 ′. When the elastic arm 50 is moved toward the misaligned plate 41 of the main body 40, the first transverse direction The plate 5 6 will abut the misaligned plate 4 1. Please refer to FIG. 5. When the circuit board 3 8 is inserted into the electrical connector at an oblique position, it will first press the inclined surface of the upper end of the buckling portion 53 of the spring arm 50, so that The spring arm 50 bounces to the vertical plate 41. When the circuit board 3 8 reaches the positioning position, the spring arm 50 rebounds and the snap-in portion 53 is snapped on the circuit board 38. At this time, the first stopper 4 4 It is also locked in the card hole 39 on the side of the circuit board 38. From the above structure, this creative structure has a strong body 40, and
