wherein the elastic pressing sheet (27) is used to apply a predetermined pressure on the mating terminal inserted between the elastic contact member (3) and the elastic pressing sheet (27) to ensure reliable electrical contact between the mating terminal and the elastic contact member (3).


 
10. The terminal according to any one of claims 1-8,

wherein the elastic contact member (3) comprises multiple elastic arms (33) extending along a transverse direction (X) of the terminal board (1), and the multiple elastic arms (33) are arranged in a row along the longitudinal direction (Y) of the terminal board (1);

wherein multiple elastic arms (33) of the elastic contact member (3) are used for simultaneous electrical contact with the mating terminal inserted along the transverse direction (X) of the terminal board (1) between the elastic contact member (3) and the top plate (21) of the locking member (2).


 
11. The terminal according to claim 10,

wherein the elastic contact member (3) further comprises a first side edge portion (31) and a second side edge portion (32) extending along the longitudinal direction (Y) of the terminal board (10), and multiple elastic arms (33) connected between the first side edge portion (31) and the second side edge portion (32);

wherein the first side edge portion (31) of the elastic contact member (3) is fixed to the top surface (1a) of the terminal board (1), and the second side edge portion (32) of the elastic contact member (3) is slidably supported on the top surface (1a) of the terminal board (1).


 
12. The terminal according to claim 10,
wherein multiple support protrusions (11c) are formed on the top surface (1a) of the terminal board (1), and the multiple support protrusions (11c) are respectively located at the left and right sides of the elastic contact member (3) to support the inserted mating terminal and prevent the elastic arms (33) of the elastic contact member (3) from being excessively compressed by the mating terminal.
 
13. The terminal according to claim 1,
wherein each of the terminal board (1), the locking member (2) and the elastic contact member (3) is an integral stamped part.
 
14. The terminal according to claim 1,

wherein the locking member (2) is fixed to the front end part of the terminal board (1), and the rear end part of the terminal board (1) extends backwards along the longitudinal direction (Y) of the terminal board (1) beyond the locking member (2);

wherein the top surface (1a) of the rear end part of the terminal board (1) is used for welding to a cable for electrical connection with the cable.


 
15. A connector, comprising:

a housing; and

the terminal of any one of claims 1-14, which is inserted into the housing.
