Battery terminal with unintended deformation prevention features

A battery terminal to be mounted on a battery post provided on a battery, comprising a terminal main body and a fastening member, wherein:

• the terminal main body includes an upper plate, a lower plate arranged parallel to the upper plate and first and second receiving portions connected to the upper plate;
• the upper plate includes an upper plate mounting hole, the battery post being inserted through the upper plate mounting hole, and an upper plate slit extending from an edge of the upper plate mounting hole to an end edge of the upper plate, a part arranged at a first side of the upper plate slit is a first upper plate fastening portion and a part arranged at a second side is a second upper plate fastening portion;
• the lower plate includes a lower plate mounting hole, the battery post being inserted through the lower plate mounting hole, and a lower plate slit extending from an edge of the lower plate mounting hole to an end edge of the lower plate, a part arranged at a first side of the lower plate slit is a first lower plate fastening portion and a part arranged at a second side is a second lower plate fastening portion;
• the first receiving portion includes a first receiving wall, a first engaging portion and a first overlapping portion;
• the first receiving wall has an arcuate cross-section, extends from an end edge of the first upper plate fastening portion on a side opposite to the second upper plate fastening portion toward the first lower plate fastening portion and has a convex surface on a side opposite to a side facing the first upper plate fastening portion and the first lower plate fastening portion;
• the first engaging portion is connected to an end edge of the first receiving wall proximate to the first lower plate fastening portion, extends perpendicularly to the first lower plate fastening portion and is in contact with an end surface of the first lower plate fastening portion;
• the first overlapping portion is connected to the end edge of the first receiving wall proximate to the first lower plate fastening portion, extends in parallel to the first lower plate fastening portion and is placed on a surface facing the first upper plate fastening portion;
• the second receiving portion includes a second receiving wall, a second engaging portion and a second overlapping portion;
• the second receiving wall has an arcuate cross-section, extends from an end edge of the second upper plate fastening portion on a side opposite to the first upper plate fastening portion toward the second lower plate fastening portion and has a convex surface on a side opposite to a side facing the second upper plate fastening portion and the second lower plate fastening portion;
• the second engaging portion is connected to an end edge of the second receiving wall proximate to the second lower plate fastening portion, extends perpendicular to the second lower plate fastening portion and is in contact with an end surface of the second lower plate fastening portion;
• the second overlapping portion is connected to the end edge of the second receiving wall proximate to the second lower plate fastening portion, extends parallel to the second lower plate fastening portion and is placed on a surface facing the second upper plate fastening portion;
• a nut is arranged between the first and second upper plate fastening portions and the first and second lower plate fastening portions;
• the fastening member includes a base to be placed on the upper plate portion and a first pressing portion and a second pressing portion connected to the base;
• surfaces of the first and second pressing portions facing each other are a first tapered surface and a second tapered surface inclined in directions to be more separated from each other with distance from the base;
• and
• the first tapered surface is in contact with the first receiving portion and the second tapered surface is in contact with the second receiving portion.
