Zusammenfassung:A contact piece structure includes a piece body (1) having a slot (2). The slot (2) has opposite first and second sidewalls (22). The first sidewall (21) has a first plane portion (211) and a protrusion (212), the second sidewall (22) has a second plane portion (221) and a recess (222) recessed into the second plane portion (221) and corresponding to the protrusion (212). A first distance (dl) from a top end of the protrusion (212) of the first sidewall (21) to a plane where the second plane portion (221) is positioned is less than a thickness (d3) of the piece body (1).
