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.

Claim 1
Independent Claim
215 words
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 said first and second elastic contact elements, and a narrowly-spaced lead pin clamping portion formed between said opposite surfaces, said lead pin inserted into said lead pin loose insertion portion being brought into said narrowly-spaced lead pin clamping portion by moving said lead pin in a horizontal direction, thereby assuring a reliable electrical contact, wherein a pair of normally-inclining slant sides for guiding said lead pin into said narrowly-spaced lead pin clamping portion from said lead pin loose insertion portion are said narrowly-spaced lead pin clamping portion, a pair of clamping sides forming said 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 said pair of reversely-inclining slant sides forming said narrowly-spaced lead pin clamping portion and said pair of normally-inclining slant sides forming said lead pin guide portion are arranged in such a manner as being displaced in a horizontal direction from each other.
Claim 2
Dependent Claim
215 words
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 said first and second elastic contact elements, and a narrowly-spaced lead pin clamping portion formed between said opposite surfaces, said lead pin inserted into said lead pin loose insertion portion being brought into said narrowly-spaced lead pin clamping portion by moving said lead pin in a horizontal direction, thereby assuring a reliable electrical contact, wherein a pair of normally-inclining slant sides for guiding said lead pin into said narrowly-spaced lead pin clamping portion from said lead pin loose insertion portion are said narrowly-spaced lead pin clamping portion, a pair of clamping sides forming said 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 said pair of reversely-inclining slant sides forming said narrowly-spaced lead pin clamping portion and said pair of normally-inclining slant sides forming said lead pin guide portion are arranged in such a manner as being displaced in a horizontal direction from each other.
Claim 3
Dependent Claim
55 words
A socket contact as claimed in claim 1, wherein distal end portions of said first and second elastic contact elements are inclined forwardly in an opposing direction relatively to each other, and the normally-inclining slant sides and the reversely-inclining slant sides are formed by edges on opposing surfaces side of the forwardly inclining end portions.
Claim 4
Dependent Claim
39 words
A socket contact as claimed in claim 1 or 2, wherein a distal end portion of one of said first and second elastic contact elements is located in a position higher than a distal end portion of the other.
Claim 5
Dependent Claim
41 words
A socket contact as claimed in claim 1 or 2, wherein a support element is provided along one side of each of said first and second elastic contact elements, and said lead pin loosely-insertion portion is formed between said support elements.
