7. A convertible plugboard as claimed in claim 6, wherein: the outer height of the circular ring of the ground wire conductive sleeve ring (43) is higher than that of the zero line conductive sleeve ring (41); as such, when the neutral contact (213) and the neutral conductive collar (41) are disengaged, the ground conductive collar (43) also maintains contact with the ground contact (212).
8. A convertible plugboard as claimed in claim 6, wherein: the contact range of the ground wire conductive sleeve ring (43) and the ground wire contact (212) is larger than that of the live wire contact (211) and the live wire reset contact ring (47); thus, when the hot contact (211) and the hot return contact ring (47) are disengaged, the ground conductive collar (43) remains in contact with the ground contact (212).
9. A convertible plugboard as claimed in claim 8, wherein: the outer height of the circular ring of the ground wire conductive sleeve ring (43) is higher than that of the zero line conductive sleeve ring (41); as such, when the neutral contact (213) and the neutral conductive collar (41) are disengaged, the ground conductive collar (43) also maintains contact with the ground contact (212).
