An electrical connector includes: a circuit board, provided with multiple accommodating holes, where each accommodating hole is circular shaped; multiple terminals, where each terminal includes a base, and the base is accommodated in a corresponding accommodating hole; and multiple strip connecting portions, configured to be connected to a corresponding one of the first strips. One strip connecting portion and the corresponding base are fixed to each other. When the strip connecting portion and the corresponding base are inserted into the corresponding accommodating hole, the strip connecting portion supports and abuts the corresponding base, such that the corresponding terminal is not easily deformed or rotated during the insertion, and the corresponding terminal is not easily damaged. The strip connecting portion, the corresponding base and the corresponding accommodating hole form a contact of at least three points, ensuring the corresponding terminal to be stably fixed in the corresponding accommodating hole.
