ABSTRACT:
A contact socket having a first and a second elastic contact elements extending in an insertion direction (vertical direction) of a lead pin of an electric part, a lead pin loose insertion portion formed between and along opposite surfaces of the first and second elastic contact elements, and a narrowly-spaced lead pin clamping portion formed between the opposite surfaces, the lead pin inserted into the lead pin loose insertion portion being brought into the narrowly-spaced lead pin clamping portion by moving the lead pin in a horizontal direction, thereby assuring a reliable electrical contact, wherein a pair of normally-inclining slant sides for guiding the lead pin into the narrowly-spaced lead pin clamping portion from the lead pin loose insertion portion are formed between the lead pin loose insertion portion and the narrowly-spaced lead pin clamping portion, a pair of clamping sides forming the narrowly-spaced lead pin clamping portion are formed as reversely-inclining slant sides connected respectively at one ends thereof to one ends of the normally-inclining slant sides and gradually enlarging toward the other ends thereof, and positions of connecting areas between the pair of reversely-inclining slant sides forming the narrowly-spaced lead pin clamping portion and the pair of normally-inclining slant sides forming the lead pin guide portion are arranged in such a manner as being displaced in a horizontal direction from each other.
