Patent ID: 7736194

Claim:
An universal electrical plug, comprising: a first support and a second support separated by a space so as not to be in physical contact with each other, a through hole being defined on the second support with an axis extending form the through hole to the first support; a plurality of inner electrode slats juxtaposed on the second support to surround the through hole, and each of the inner electrode slats extending across the space separating the first support and the second support in a direction parallel to the axis; each of the inner electrode slats including at least one inner deforming section in the middle thereof and arranged in the space separating the first support and the second support, a first end connected to the second support, and a third end connected to the first support; a distance from each of the inner deforming sections to the axis being normally smaller than the distance from the first end to the axis, the inner deforming section being deformable to change the distance from the inner deforming section to the axis; and a plurality of outer electrode slats, juxtaposed on the second support to surround the through hole, and each of the outer electrode slats extending across the space separating the first support and the second support in a direction parallel to the axis; a distance from each of the outer electrode slats to the through hole being larger than the distance from each of the inner electrode slats to the through hole; each of the outer electrode slats including at least one outer deforming section in the middle thereof and arranged in the space separating the first support and the second support, a second end connected to the second support, and a fourth end connected to the first support; a distance from each of the outer deforming section to the axis being large than the distance from the second end the axis, the outer deforming section being deformable to change the distance from the outer deforming section to the axis.
