Prevent falling electric connector of tin

The utility model discloses a prevent falling electric connector of tin, include conductive terminal and be fixed with conductive terminal's insulator, conductive terminal has contact site and weldingfoot, the insulator has been offered and has been used for the holding the welding foot the welding groove and with the welding groove corresponds overlaps the tin adding groove of intercommunicationin order to be used for placing tin ingot or tin bar, the interior ora terminalis in tin adding groove is with corresponding welding groove intercommunication, the outer end along form with the opening of external intercommunication, the open -ended width in tin adding groove is less than the width of the at least subregion of tin adding inslot portion. Compared with the prior art, the tin addinggroove is designed for its open -ended width is less than its inside width of subregion at least, because the softer characteristic of tin itself for impressed as tin bar or tin ingot during the tinadding groove, it can be bas
