Abstract

Abstract This invention is directed to an electronic component with a plurality of terminals thereon for liquid crystal display apparatus or the like. Since the construction is rendered smaller in size and the distributing sheet is rendered rigid in the contact position of the elastic conductor along the juxtaposing direction of the terminal pieces, the terminal pieces of the base plate can be electrically conducted, without failure the terminals through the elastic conductors.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 252 words
An electronic component with a plurality of terminals thereon comprising in combination a rigid base plate having a plurality of terminal pieces juxtapositioned thereon next to each other and secured on one surface of said base plate, an interposing member provided with elastic flexible conductors having first and second end portions, each conductor extending in the thickness direction through said interposing member substantially perpendicular and corresponding to each of said terminal pieces, said interposing member adapted to retain said elastic conductors mutually insulated one from the other, said first end portions along the thickness direction of each of said elastic conductors being in individual contact with each of said terminal pieces on said base plate, a distributing sheet secured by way of said interposing member to an end portion of said base plate, the surface of said distributing sheet facing said interposing member being provided with a plurality of flexible terminals thereon in electrical contact with said second end portions of said elastic conductors, said flexible terminals being in electrical connection with said terminal pieces on said base plate along the thickness of said elastic conductors, a rigid support plate having a flat face superimposed and bonded over its entire surface to an end portion of said distributing sheet corresponding to said end portion of said base plate, said flexible terminals being held rigid therebetween in contact with said elastic conductors by said rigid support plate, so as to maintain electrical contact at all times between said elastic conductors and said terminals.
Claim 2
Dependent Claim 252 words
An electronic component with a plurality of terminals thereon comprising in combination a rigid base plate having a plurality of terminal pieces juxtapositioned thereon next to each other and secured on one surface of said base plate, an interposing member provided with elastic flexible conductors having first and second end portions, each conductor extending in the thickness direction through said interposing member substantially perpendicular and corresponding to each of said terminal pieces, said interposing member adapted to retain said elastic conductors mutually insulated one from the other, said first end portions along the thickness direction of each of said elastic conductors being in individual contact with each of said terminal pieces on said base plate, a distributing sheet secured by way of said interposing member to an end portion of said base plate, the surface of said distributing sheet facing said interposing member being provided with a plurality of flexible terminals thereon in electrical contact with said second end portions of said elastic conductors, said flexible terminals being in electrical connection with said terminal pieces on said base plate along the thickness of said elastic conductors, a rigid support plate having a flat face superimposed and bonded over its entire surface to an end portion of said distributing sheet corresponding to said end portion of said base plate, said flexible terminals being held rigid therebetween in contact with said elastic conductors by said rigid support plate, so as to maintain electrical contact at all times between said elastic conductors and said terminals.
Claim 3
Dependent Claim 31 words
The electric component of claim 1, further including spacer means juxtapositioned and bonded to said base plate on either side of said interposing member so as to further support said terminals.
