two elastic sheets disposed facing each other in a length direction, each of the elastic sheets having: a body portion; and an elastic contact portion protruding from the body portion in a height direction;
a connection sheet having: a first connecting portion extending in the height direction; and a second connecting portion extending in the length direction;
the first connecting portion of the connection sheet being fixed between the body portions of the two elastic sheets, the second connecting portion being positioned outside the two elastic sheets in the length direction;
wherein the second connecting portion is spaced apart from the first connecting portion in the length direction; and
the connection sheet further has a third connecting portion positioned between the first connecting portion and the second connecting portion, and the third connecting portion is connected with the first connecting portion and the second connecting portion.

2. The mating terminal according to claim 1 , wherein the elastic contact portion of each elastic sheet has: a first extending segment connected to the body portion and extending obliquely toward the other elastic sheet in the height direction; and a second extending segment connected to the first extending segment and extending obliquely away from the other elastic sheet in the height direction.

3. The mating terminal according to claim 1 , wherein the elastic contact portion of each elastic sheet is provided as multiple in number, the multiple elastic contact portions are spaced apart from each other in a width direction.

4. The mating terminal according to claim 1 , wherein
the mating terminal comprise a protective shell having two first side walls disposed facing each other in the length direction;
the elastic contact portion of each elastic sheet is positioned between the two first side walls of the protective shell and elastically presses against the corresponding first side wall so as to be fixed to the protective shell.

5. The mating terminal according to claim 4 , wherein
the protective shell further has: two top walls spaced apart from each other in the length direction, each of the top walls is correspondingly connected to one of the first side walls and extends toward the other of the first side walls in the length direction;
a top end of the elastic contact portion of the elastic sheet away from the main body portion elastically presses against the top wall from below the top wall of the protective shell.

6. The mating terminal according to claim 1 , wherein the second connecting portion of the connection sheet is directly connected to the first connecting portion.

7. A multifunctional high-voltage connector, comprising:
an upper cover;
a pedestal assembled with the upper cover;
a conductive connection structure fixedly mounted to the upper cover;
