An electrical connector includes a base and an elastic terminal. The base has a recess. The elastic terminal is connected to the base and extends to the recess. The elastic terminal has a fixed end and a free end, the fixed end is connected to the base, and the free end is located at the recess and is curved. When the contact moves towards the recess, the contact is capable of pushing the contact protrusion to bend towards the bottom of the recess so that the free end leans against the bottom of the recess. The electrical connector may further include a contact protrusion connected to the elastic terminal. When the contact moves towards the recess, the contact is capable of pushing the contact protrusion to make the elastic terminal bend towards the bottom portion of the recess so that the free end leans against the bottom of the recess.
