The flatness of the docking, thereby improving the combination with the docking electrical connector. Several terminals 20 are provided with a holding portion 210 fixed on the base 110 of the insulating body 10, a contact portion 220 extending forward from the holding portion 210 along the receiving groove 123, and a welding portion 230 extending backward from the holding portion 210; The front end of the receiving groove 123 is provided with a protruding block 125 (please refer to FIG. 5 ), and the protruding block 125 is located at the front end of the contact portion 220 of the terminal 20, which can prevent the terminal of the electrical connector of the present utility model from being damaged when the butt electrical connector is inserted. 20.

1 and 2, the shielding housing 30 has an upper side wall 310, a lower side wall 320, and two end side walls 330. The four side walls are connected end to end and cover the insulating body. The outer side is formed with a docking frame. Both ends of the front edge of the upper side wall 310 are provided with a mating portion 311 protruding to the inside of the electrical connector, and the mating portion 311 is cut from the front edge of the upper side wall 310 to form a slot 312 (in this embodiment The slot is a "" type slot, of course, the slot can also be cut into other shapes), and a bending piece 313 is bent into the docking frame, and the bending piece 313 is roughly perpendicular to the upper side wall 310 , the bent piece 313 can cooperate with the slot of the butt connector to guide the insertion of the butt connector (please refer to the subsequent detailed description).
