Abstract
A contact comprising an electrically conductive material plate defining a central planar contact base. A plurality of integral contact leaves extend spirally from the base, and a plurality of integral mounting tabs extend radially from the base. The leaves are mechanically deformed from the plane of the base to form independent spring contacts. The tabs are coplanar with the base. A metal plating containing interconnect particles is provided on the contact base and leaves.
Claims14
An electrical contact comprising:
- a substrate;
- a first contact segment projecting in a first direction from a substrate plane;
- and
- at least one second contact segment formed in a radial spiral relative to said first contact segment and projecting in a second direction from said substrate which is opposite that of said first contact.
An electrical contact comprising:
- a central contact segment projecting in a first direction from a substrate plane;
- and
- at least one contact wing contiguous with, and bent to project in a second direction from said substrate which is opposite that of said central contact.
An electrical contact comprising:
- an electrically conductive material plate defining a central planar contact base;
- a plurality of integral mounting tabs coplanar with and extending from said base;
- and
- a plurality of contact leaves integral with and extending spirally from said base, said leaves being mechanically deformed from the plane of said base to form independent spring leaf contacts.
