PURPOSE: To prevent crack of solder for connecting a pin to a through hole on the basis of the thermal expansion by providing raised bottom banks in which supporting protrusions are provided on four corners on the lower surface of a connector base made of insulating synthetic resin. CONSTITUTION: Two connector pins 4 to serve as energizing terminals are inserted into and attached to a connector base 3 made of insulating synthetic resin, and formed into a thick and square flat plate in the vertical direction. Raised bottom banks 6 are provided across the total length of the outer peripheral of the lower surface circumference of this connector base 3, and supporting protrusions 7 whose tips are narrowed, and having rich elasticity are provided in four corners of this raised bottom banks 6. One end of the connector pin 4 is inserted into a through hole 2 of a printed circuit board 1 until the tips of the supporting protrusions 7 on the lower ends of the connector base 3 are brought in contact, and it is soldered to the through hole 2, so as to be used. |
