Theresilient contact 222 extends forwardly into thetongue plate 102 and is exposed at the surface of thetongue plate 102. Theadditional portion 15 extends downwardly from thebottom wall 17. Theadditional portion 15 includes twoopposite side portions 151 and arear portion 154 connecting the twoside portions 151, and the twoside portions 151 and therear portion 154 form areceiving space 156 opened forward and downward. Therear portion 154 is provided with a vertically extendingterminal receiving groove 155, and thesoldering portion 223 is received in theterminal receiving groove 155.

Theouter housing 40 includes a firsttop wall 41, twofirst side walls 42 bent downward from two side edges of the firsttop wall 41, and a firstrear wall 46 bent downward from a rear edge of the firsttop wall 41. Theouter shell 40 is provided with awelding foot 45 extending downwardly from the lower edge of thefirst side wall 42 thereof. Theside portion 151 is provided with abending portion 152 bent outward and backward from the front end thereof, and aholding groove 153 is formed between thebending portion 152 and theside portion 151.
