Power distribution component and power distribution device

A power distribution device comprising:

• a power distribution component plugged into a power distribution box, wherein the power distribution box comprises a box body, a first power busbar, a second power busbar, and a signal busbar, wherein the first power busbar, the signal busbar, and the second power busbar are sequentially arranged in the box body along a first direction;
• wherein the power distribution component comprises a main body comprising a first end and a second end that are disposed opposite to each other, the second end provided with a first power terminal, a signal terminal, and a second power terminal that are sequentially arranged along a first direction, the first power terminal is electrically connected to the first power busbar, the signal terminal is electrically connected to the signal busbar, the second power terminal is electrically connected to the second power busbar, and polarities of the first power terminal and the second power terminal are opposite;
• and
• the power distribution component further comprises a mistake proofing structure protruding at the second end, the mistake proofing structure comprising an abutting surface facing away from the main body and located at an end of the mistake proofing structure, and the abutting surface is configured to abut against the signal busbar when the power distribution component is incorrectly inserted into the power distribution box;
• wherein an end surface of the second end of the main body is provided with a first power insertion slot, a signal insertion slot, and a second power insertion slot that are sequentially arranged along the first direction, the first power terminal is disposed on an inner side surface of the first power insertion slot, the signal terminal is disposed on an inner side surface of the signal insertion slot, the second power terminal is disposed on an inner side surface of the second power insertion slot, the first power insertion slot is configured to engage with the first power busbar, the signal insertion slot is configured to engage with the signal busbar, and the second power insertion slot is configured to engage with the second power busbar;
• wherein the mistake proofing structure is disposed between the first power insertion slot and the signal insertion slot, and/or the mistake proofing structure is disposed between the signal insertion slot and the second power insertion slot;
• and
• wherein the main body further comprises a body top surface and a body bottom surface that are disposed in parallel and opposite to each other, the power distribution component having a central plane, the central plane being perpendicular to the first direction, wherein a vertical distance between the central plane and the body top surface is the same as a vertical distance between the central plane and the body bottom surface, a position of the first power insertion slot and a position of the second power insertion slot are disposed symmetric about the central plane, the abutting surface comprises an effective abutting surface configured to come into contact with the signal busbar when the power distribution component is incorrectly inserted into the power distribution box, a distance between the effective abutting surface and the central plane is a first distance, a distance between an inner side surface, close to the mistake proofing structure, of the signal insertion slot and the central plane is a second distance, and the first distance is the same as the second distance.
