The insulating block 21 is injection molded on the fixing portion 221, so that a gap between the insulating block 21 and the fixing portion 221 is avoided. The resilient contact 222 extends forwardly into the tongue plate 102 and is exposed at the surface of the tongue plate 102. The additional portion 15 extends downwardly from the bottom wall 17. The additional portion 15 includes two opposite side portions 151 and a rear portion 154 connecting the two side portions 151, and the two side portions 151 and the rear portion 154 form a receiving space 156 opened forward and downward. The rear portion 154 is provided with a vertically extending terminal receiving groove 155, and the soldering portion 223 is received in the terminal receiving groove 155.

The outer housing 40 includes a first top wall 41, two first side walls 42 bent downward from two side edges of the first top wall 41, and a first rear wall 46 bent downward from a rear edge of the first top wall 41. The outer shell 40 is provided with a welding foot 45 extending downwardly from the lower edge of the first side wall 42 thereof. The side portion 151 is provided with a bending portion 152 bent outward and backward from the front end thereof, and a holding groove 153 is formed between the bending portion 152 and the side portion 151. The welding foot 45 is held in the holding groove 153. The lower edge of the first side wall 42 is bent inward to form a catch 43. The main body 12 includes an extension 13 extending downward from a side wall 18 thereof beyond a bottom wall 17, a latching groove 14 is formed between the extension 13 and the additional portion 15, and the retaining portion 43 is retained in the latching groove 14. The main body 12 includes a protrusion 121 protruding outward from an outer side surface thereof, the protrusion 121 extends rearward from the frame 11, and the first sidewall 42 is provided with a locking groove 44 matching with the protrusion 121.
