Abstract

PURPOSE: To prevent the damage of the soldered part of a leg terminal due to the difference of thermal shrinkage of a base from that of a printed substrate by fitting and fixing a fixed leg formed in the lower face of a base, in the hole of the printed substrate. CONSTITUTION: A fixed leg 6 hung vertically under the lower face of an insulating base 1 made of synthetic resin is fitted and fixed in the hole 8 of a printed substrate 4. Consequently, even if there is a difference between the thermal shrinkage of a printed substrate 4 and the thermal shrinkage of the base 1 made of synthetic resin, of a leg terminal 3 a part to be raised in the printed substrate 4 is bent and deformed to absorb the difference of the thermal shrinkage and thus a soldered part 5 of the leg terminal 3 is made hard to be damaged. Also, in the case an IC, a transistor, an electric or electronic apparatus, e.g. a resistor, etc., are attached to or detached from a connector terminal 2, the fixed leg 6 of the base 1 receives the force applied to the connector terminal 2 and the force to be applied to the leg terminal 3 can be lowered. It is preferable that the fixed leg 6 is fitted in the hole 8 by elastic fitting.
