Electrical connector, electrical mating connector, and electrical connector assembly

An electrical connector assembly, comprising:

• an electrical connector, comprising:
• a housing;
• and
• a terminal member disposed in the housing, comprising a first terminal and a second terminal opposite to the first terminal, the first terminal comprising a first bump part and a first notch part, the first bump part being disposed at one side of the first notch part, the second terminal comprising a second bump part and a second notch part, the second bump part being disposed at one side of the second notch part, the first bump part being opposite to the second notch part, the second bump part being opposite to the first notch part;
• and
• an electrical mating connector inserted in the electrical connector, comprising a mating housing and a terminal component disposed in the mating housing, the terminal component comprising a first terminal and a second terminal opposite to the first terminal, a surface of the first terminal and a surface of the second terminal oppositely disposed being anti-friction surfaces, the terminal member of the electrical connector being electrically connected to the terminal component of the electrical mating connector;
• wherein one ends of the plurality of first elastic pieces and one ends of the plurality of second elastic pieces respectively abut against the anti-friction surfaces.
