wherein the elastic wire pressing assembly 4 and the electric conductor 3 are positioned inside the insulating shell 1;

the elastic pressing assembly 4 includes a locking member 41, an operating member 42, and an elastic member 43, wherein the pressing member 22 fixes the locking member 41 by abutting against the locking member 41, the locking member 41 is connected with the electric conductor 3, and the operating member 42 can perform linear reciprocating sliding movement relative to the locking member 41;

one end of the elastic piece 43 is fixedly connected with the locking piece 41, and the other end is a free end 4331; a cable can be clamped between the free end 4331 and the locking piece 41, so that the cable and the conductor 3 form conductive connection;

Two ways of inserting the cable into the terminal connector are listed below. The first way is: the insulating gland 2 is sleeved on the cable in advance, at the moment, the insulating gland 2 is not mounted on the insulating shell 1, then the operating piece 42 is manually pressed, so that the gap between the free end 4331 and the locking piece 41 is enlarged, a cable is inserted into the gap between the free end 4331 and the locking piece 41, then the pressing is stopped, and finally the insulating gland 2 and the insulating shell 1 are assembled into a whole, so that the cable mounting operation is completed, and the assembly mode is quick; the second way is: the terminal connector is assembled into a whole, and then the operation member 42 is pressed by the auxiliary pressing tool, so that the gap between the free end 4331 and the locking member 41 is enlarged, and the cable is inserted into the gap between the free end 4331 and the locking member 41 and then the pressing is stopped, thereby completing the cable installation operation.
