Patent attributes
An assembled structure. A first substrate having a base surface is connected to a second substrate by at least one metallic clamping device. The clamping device, vertically disposed on the second substrate, comprises two parts: a first half and a second half having a supporting surface. The first half comprises a main unit and a plurality of spaced arm units disposed on the main unit, and each arm unit comprises a first part extending from the main unit and a second part extending from the first part. When the base surface of the first substrate contacts the supporting surface of the second half, at least one of the second parts of the arm units presses the first substrate on the second half, so that the first substrate is positioned by and electrically connected to the clamping device.
