Claim Text:
1. An electrical connection device, comprising: a first circuit board, having a plurality of first signal electrodes and at least one first test electrode, wherein the first signal electrodes and the first test electrode are arranged in a spaced manner on a same side of the first circuit board; and a second circuit board, having a plurality of second signal electrodes and at least one second test electrode, wherein the second signal electrodes and the second test electrode are arranged in a spaced manner on a same side of the second circuit board, wherein the first signal electrodes are electrically connected to the second signal electrodes, and the first test electrode is electrically connected to the second test electrode to form a testing loop; wherein the first test electrode and the second test electrode are configured to determine whether the first signal electrodes and the second signal electrodes are electrically connected to each other by detecting whether the testing loop is a short circuit or an open circuit.
