A spring-connected grounding terminal for connecting to a grounding end for grounding of at least one conductive wire, wherein the grounding terminal comprises a current bar bracket, on which at least one terminal is connected, wherein: at least one current bar connecting end is disposed on the current bar bracket, wherein the at least one current bar connecting end is connected to -a the at least one terminal; the at least one terminal comprises a housing (1,2), a spring, and a handle, a first support bolt and a second support bolt are disposed inside the housing, wherein the spring is sleeved on the first support bolt, and the spring is configured to have an open state and a closed state; a clamping slot is disposed on the housing; a first through hole, which mates with the second support bolt, is disposed on the handle; a hollowed-out portion is disposed on the handle; the spring has, at one end, two support legs, which are connected to an executing arm through a clamp arm, wherein the executing arm is connectable with respect to the conductive wire inserted into the at least one terminal, the clamp arm is rotatably installed inside the first support bolt, and the handle is bridged inside the two support legs, wherein a first stopper is disposed on the handle, when the handle is in an open state, the first stopper extends between the two support legs and the front end of the handle is in contact with the two support legs of the spring; the executing arm at the other end of the spring mates with the current bar bracket to connect the the at least one conductive wire; the current bar connecting end has a base portion and a retaining arm connecting to two side edges of an upper portion above the base portion and perpendicular to the base portion, wherein the retaining arm has a transition edge, a retaining edge, and a clamping edge connecting the transition edge and the retaining edge; when the spring is in a closed state, the hollowed-out portion mates with the clamping slot and the two support legs of the spring are in contact with the clamping edge; when the spring is in an open state, the hollowed-out portion is in a separate state with respect to the clamping slot and the two support legs of the spring are in a separate state with respect to the current bar connecting end; the current bar bracket has a second through hole configured to be connected to the grounding end disposed therein, and positioning holes are disposed at two sides of the second through hole, the positioning holes configured to be mated with a convex portion disposed on the grounding end to secure the position of the current bar bracket. at least one current bar connecting end is disposed on the current bar bracket, wherein the at least one current bar connecting end is connected to -a the at least one terminal; the at least one terminal comprises a housing (1,2), a spring, and a handle, a first support bolt and a second support bolt are disposed inside the housing, wherein the spring is sleeved on the first support bolt, and the spring is configured to have an open state and a closed state;
