[0046] The following embodiments are further illustrated with reference to the accompanying drawings, which further illustrate the specific embodiments of an electrical connection terminal and a relay socket according to the present application. The electrical connection terminal and the relay socket according to the present application are not limited to the description of the following embodiments. Figures 1 to 22

[0047] ​​​​​​An electric connection terminal comprises a terminal seat 1 and a clamping spring 2, the terminal seat 1 is electrically connected with the clamping spring 2, the terminal seat 1 comprises a first clamping end 11, an elastic section 13 and a second clamping end 12 which are integrally formed and connected in sequence, the first clamping end 11 and the second clamping end 12 of the terminal seat 1 are oppositely folded and form a terminal gap 14 between the first clamping end 11 and the second clamping end 12; when the terminal seat 1 is operated by an operating member to make the elastic section 13 deform, the first clamping end 11 and the second clamping end 12 move oppositely to make the terminal gap 14 correspondingly narrow or expand, and an external wire 3 inserted into the terminal gap 14 is clamped or released along with the narrowing or expanding of the terminal gap 14.

[0048] The electric connection terminal of the present application does not use terminal screws to connect, the terminal seat 1 is integrally formed and folded, and does not need to be connected or fixed with other terminal plates, the first clamping end 11 and the second clamping end 12 are oppositely arranged after being folded, the first clamping end 11 and the second clamping end 12 are made to approach or move away from each other by making the elastic section 13 deform to adjust the narrowing or expanding of the terminal gap 14, and the external wire 3 inserted into the terminal gap 14 is clamped or released in the process, the connection mode is simple, and the problem of poor connection caused by the slipping, breaking or falling of terminal screws does not occur.

[0049] As shown in Figures 1-4 An electric connection terminal comprises a terminal seat 1 and a clamping spring 2, the terminal seat 1 is electrically connected with the clamping spring 2, the terminal seat 1 comprises a first clamping end 11, an elastic section 13 and a second clamping end 12 which are integrally formed and connected in sequence, the first clamping end 11 and the second clamping end 12 of the terminal seat 1 are oppositely folded and form a terminal gap 14 between the first clamping end 11 and the second clamping end 12, the external wire 3 to be connected is inserted into the terminal gap 14; when the terminal seat 1 is operated by an operating member to make the elastic section 13 deform, the first clamping end 11 and the second clamping end 12 move oppositely to make the terminal gap 14 correspondingly narrow or expand, when the terminal gap 14 expands, the external wire 3 is released by the first clamping end 11 and the second clamping end 12; when the terminal gap 14 narrows, the external wire 3 is clamped by the first clamping end 11 and the second clamping end 12.

[0050] To ensure stable connection, preferably as shown in Figures 1-4As shown, the first clamping end 11 and the second clamping end 12 have an overlapping relative area. The first clamping end 11 covers the outside of the second clamping end 12, or the second clamping end 12 covers the outside of the first clamping end 11. In this case, the wiring gap 14 is set within the overlapping relative area, and the elastic segment 13 is set on the side opposite to the overlapping relative area. The deformation of the elastic segment 13 causes the first clamping end 11 to move relative to the second clamping end 12. In this structure, the sidewalls of the first clamping end 11 and the second clamping end 12 exert force on the external wire 3. Of course, the first clamping end 11 and the second clamping end 12 may not have an overlapping relative area. In this case, the ends of the first clamping end 11 and the second clamping end 12 need to be directly opposite each other, and the gap between the ends is the wiring gap. When the elastic segment 13 deforms, it cannot produce a swing in a direction other than deformation. Such a structure is not as stable as the structure with an overlapping relative area, and the requirements for the elastic segment 13 are higher.

[0051] As an optimized structure, such as Figure 1 , 3 As shown, a first slit 15 that cooperates with the operating member can be opened in the middle of the first clamping end 11. The first slit 15 divides the first clamping end 11 into two relatively independent first clamping ends 11. A second slit 16 that cooperates with the operating member is opened in the middle of the second clamping end 12. The second slit 16 divides the second clamping end 12 into two independent second clamping ends 12 that correspond to the two first clamping ends 11. The first slit 15 and the second slit 16 are preferably arranged in a symmetrical structure along the center line of the terminal block 1, which is conducive to the stable installation of the terminal block 1. At the same time, the arrangement of the first slit 15 and the second slit 16 is also conducive to the operating member extending into the terminal block 1 to change the reduction or expansion of the wiring gap 14.

[0052] As another type of optimized structure, such as Figure 3 , 4 As shown, a protruding force-bearing part 13b can be provided on the side of the elastic segment 13 away from the wiring gap 14. The force-bearing part 13b, in cooperation with the operating element, causes the elastic segment 13 to deform, thereby expanding or shrinking the wiring gap 14 between the first clamping end 11 and the second clamping end 12 to meet the wiring requirements of the external wire 3. Of course, the two optimized structures of the terminal block 1 can be used in combination.

[0053] Preferably, terminal block 1 is configured as follows: Figures 1-4The first clamping end 11, the elastic section 13 and the second clamping end 12 are sequentially connected to form a frame structure in the shape of a right-angled trapezoid, the first clamping end 11 is bent downward, the second clamping end 12 is bent upward and covers the outside of the first clamping end 11, the first clamping end 11 and the second clamping end 12 are oppositely inclined to form the hypotenuse of the frame structure, the elastic section 13 is a right angle opposite to the hypotenuse and is connected between the first clamping end 11 and the second clamping end 12, and the wiring gap 14 is located on the hypotenuse of the frame structure; the end of the second clamping end 12 is bent outward to form a hook 17 for limiting installation, the hook 17 can be matched with the edge of the wiring port 8 for limiting, of course, the structure for limiting installation of the second clamping end 12 can be a protrusion, a groove or a pull ring, etc., the end of the first clamping end 11 is provided with a knife edge 18, the inclination direction of the knife edge 18 and the inclination direction of the wiring gap 14 form an angle, when the external wire 3 is clamped, the knife edge 18 of the first clamping end 11 can further clamp the external wire 3, preventing the external wire 3 from being separated from the wiring seat 1 under stress. Of course, it is also feasible to set the wiring seat 1 as a frame structure in the shape of a rectangle, a trapezoid or a triangle, etc.

[0054] Further as Figures 1-4 shown, a wire clamp 19 is arranged below the second clamping end 12, the wire clamp 19 is used for the wire c connected between the clamp spring 2 and the wiring seat 1, a positioning spring 21 for limiting installation is arranged in the middle of the side wall of the clamp spring 2, and the specific positioning spring 21 is arranged at an angle with the side wall of the clamp spring 2 to prevent the clamp spring 2 from falling out of the clamp spring cavity 6.
