Abstract
An insulating layer is formed on at least one side surface of a spring portion of a contact, and a contacting portion formed on the spring portion is made narrower than the thickness of the spring portion, and a contacting surface of the contacting portion spaced from an edge portion of the insulating layer inwardly of the side surfaces of the spring portion.
Claims4
A contact comprising:
- a spring portion having opposite side surfaces spaced at a spring portion thickness and an edge surface between said opposite side surfaces extending in said spring portion thickness direction;
- a contacting portion projecting from said edge surface and having a contacting surface on an outer free end for being contacted by a terminal of an electric part, said terminal of said electric part moving said spring portion against the resilience thereof for producing a contacting force of said contacting portion against the electric part terminal;
- and
- an insulating layer on at least one surface of said spring portion and having a thickness substantially less than the spring portion thickness of said spring portion and an insulation layer edge portion along a side of said edge surface of said spring portion;
- said contacting portion having a smaller thickness than said thickness between said opposite side surfaces of said spring portion and having said contacting surface spaced from said insulating layer edge portion and inwardly from said at least one side surface of said spring portion.
2 more elements
A contact structure comprising a plurality of side by side contacts, each contact having:
- a spring portion having opposite side surfaces spaced at a spring portion thickness and an edge surface between said opposite side surfaces extending in said spring portion thickness direction;
- a contacting portion projecting from said edge surface and having a contacting surface on an outer free end for being contacted by a terminal of an electric part, said terminal of said electric part moving said spring portion against the resilience thereof for producing a contacting force of said contacting portion against the electric part terminal;
- and
- an insulating layer on at least one surface of said spring portion and having a thickness substantially less than the spring portion thickness of said spring portion and an insulation layer edge portion along a side of said edge surface of said spring portion;
- said contacting portion having a smaller thickness than said thickness between said opposite side surfaces of said spring portion and having said contacting surface spaced from said insulating layer edge portion and inwardly from said at least one side surface of said spring portion;
- said contacts each having said insulating layer thereon abutting a next adjacent contact for providing an insulating layer between each two adjacent contacts.
