The invention provides a press resilient terminal block structure, which can be conveniently inserted by a lead 5 so as to complete the electrical connection between the terminal block and the lead. The terminal block comprises a frame body 1, a conductive terminal 2, a pressing component 3 and a warping plate structure 4; wherein: the frame body 1 can be made of insulating materials and can be additionally arranged according to the number of the wires 5 required to be inserted. In the embodiment of the present invention, each frame body 1 is respectively provided for the insertion of one of the wires 5, and each frame body 1 has an actuating space 10 and a wire insertion hole 11 for the wire 5 to be inserted into the actuating space 10, and the actuating space 10 can be formed by opening one side of the frame body 1, so that the above-mentioned components can be disposed in the actuating space 10 from one side of the frame body 1.

The conductive terminal 2 is disposed in the actuating space 10 and located at a side of the frame body 1 where the wire insertion hole 11 extends toward the inside of the frame body 1, so that the wire 5 is electrically connected to the conductive terminal 2 after being inserted through the wire insertion hole 11. The conductive terminal 2 may have a large-area conductive portion 20 and a pin 21 extending from the conductive portion 20 to the outside of the frame 1, and the conductive portion 20 may be provided with engaging grains 200 to increase the friction force when contacting the conductive wires 5.

The pressing component 3 is also disposed in the actuating space 10 and includes a control member 30 and a spring plate 31 driven by the control member 30. Referring to fig. 3 and 4, in the embodiment of the present invention, the control member 30 is disposed at the other side of the actuating space 10 opposite to the conductive terminal 2, an opening 12 is disposed above the frame body 1, the control member 30 is provided with a pressing portion 300 protruding from the opening 12, a slot 300a for applying force to a tool such as a linear screwdriver is formed on the pressing portion 300, and the pressing portion 300 is further retracted into the opening 12 so that the control member 30 can drive the elastic sheet 31 to actuate in the actuating space 10, and an accommodating area 301 for overlapping the elastic sheet 31 with the elastic sheet 31 is recessed on the control member 30.

As mentioned above, the spring plate 31 has a stop edge 310, a pressing end 311 extending from the stop edge 310, and a seat 312 for stably disposing the spring plate 31 in the actuating space 10. In the embodiment of the present invention, the seat 312 is bent and extended to form a first sidewall 312a and a second sidewall 312b, the first sidewall 312a abuts against one side of the actuating space 10, and the second sidewall 312b abuts against the other side of the actuating space 10, so that the elastic sheet 31 can be supported in the actuating space 10; the seat 312 is further bent to extend an elastic section 310a to connect the stop edge 310, and the pressing end 311 extending from the stop edge 310 faces the second sidewall 312b, and when the spring plate 31 is disposed in the actuating space 10, the pressing end 311 faces the conductive terminal 2 (as shown in fig. 3).

The seesaw structure 4 is also disposed in the movement space 10 of the frame body 1, and has a pivoting portion 40, a first end portion 41 located at one side of the pivoting portion 40, and a second end portion 42 located at the other side of the pivoting portion 40, and a pivot 100 is disposed in the movement space 10 of the frame body 1, so that the pivoting portion 40 of the seesaw structure 4 is pivoted on the pivot 100, and the first end portion 41 is opposite to the wire insertion hole 11, the second end portion 42 is opposite to the control member 30, and the second end portion 42 is adjacent to the control member 30, or is moved by the control member 30 through structural connection. In the first embodiment of the present invention, the seesaw structure 4 may be made of plastic material, and is integrally formed and connected with the control member 30 by a connection portion 420, so that the control member 30 can drive the first and

second end portions

41, 42 of the seesaw structure 4 to swing as the seesaw is moved up and down.

Therefore, the pressing resilience type terminal block structure can be obtained by the structural composition.

Accordingly, as shown in fig. 3 and 4, when the lead 5 is to be inserted, the pressing portion 300 is pressed into the frame body 1 by a hand or a tool, so that the control member 30 moves downward in the actuating space 10 to pull the elastic piece 31, and the second end 42 of the rocker structure 4 swings downward by the control member 30 and the first end 41 tilts upward. Next, as shown in fig. 5, after the control member 30 is pressed down, the control member 30 will pull the elastic piece 31, that is, the stop edge 310 of the elastic piece 31 is pushed to swing the pressing end 311 thereof towards a side away from the conductive terminal 2, and meanwhile, the stop edge 310 will also abut against the control member 30 to prevent the control member 30 from moving upwards; in the illustrated embodiment of the present invention, a clamping edge 301a for abutting against the stop edge 310 is formed on the inner wall of the accommodating area 301 of the control member 30, but in other possible embodiments, as long as the stop edges 310 abut against the control member 30, sufficient resistance can be provided to prevent the control member 30 from moving upward, for example, by increasing the friction force of the abutting contact between the stop edges 310 and the control member 30.

Referring to fig. 5, when the pressing end 311 of the elastic piece 31 swings towards a side away from the conductive terminal 2, the conductive wire 5 can be inserted from the conductive wire insertion hole 11, and the conductive wire 5 is pushed to the first end 41 of the seesaw structure 4, as shown in fig. 6. At this time, the seesaw structure 4 is pushed by the conductive wire 5 to make the first end 41 swing downward and the second end 42 tilt upward, and the connection portion 420 is linked with the control member 30 to move upward, so that when the pressing end 311 swings toward the conductive terminal 2, the conductive wire 5 can be pressed against the conductive terminal 2, thereby achieving the purpose of electrical connection.

In addition, as shown in fig. 7, in another embodiment of the present invention, the rocker structure 4 can also be made of metal material, and an interlocking surface 302 opposite to the second end 42 of the rocker structure 4 is provided below the control member 30, so as to push the rocker structure 4 to actuate or be pushed by the second end 42 of the rocker structure 4 to actuate; as shown in fig. 8, the rocker structure 4 made of metal may be made of other forms, such as a metal plate formed by stamping.
