[0027] Embodiment

[0028] Referring to Figures 1 to 4 , the embodiment of the utility model provides a current terminal limiting structure, which comprises a first part 101 and a second part 103, the first part 101 is provided with a threading hole 101a, and the second part 103 is provided with a cavity 103a, characterized in that: the inner wall of the cavity 103a of the second part 103 is provided with a rack 108, the opening of the second part 103 has a first open edge 105 and a second open edge 106, and a notch 109 is arranged beside the interaction end 107 of the two;

[0029] From the interaction end 107 to the end of the second part 103, the distance between the end faces of the first open edge 105 and the second open edge 106 gradually increases;

[0030] Unlike the traditional cylindrical terminal of the current terminal, the cylindrical terminal in this embodiment has two openings separated from each other, forming a flared shape like a horn, wherein the inner wall of the cylindrical terminal is also provided with a rack 108 for clamping the copper wire after extrusion, thereby increasing the fixing effect of the copper wire and the cylindrical terminal;

[0031] Specifically, the first part 101 of the current terminal is provided with a threading hole 101a for binding with the copper wire, the second part 103 is a cylindrical terminal, which is hollow inside and is provided with a rack 108 on the inner wall of the cavity 103a, the rack 108 is a protrusion formed by the slot on the inner wall of the cavity 103a, the end of the second part 103 is connected with the interaction end 107, which contains the first open edge 105 and the second open edge 106, the distance between the first open edge 105 and the second open edge 106 gradually increases from the interaction end 107 to the end of the second part 103, forming a structure similar to a horn to adapt to the connection of copper wires with different diameters and the terminal;

[0032] It is worth noting that a notch 109 is provided at the interaction end 107, when the first open edge 105 and the second open edge 106 are extruded, the interaction end 107 is more easily deformed due to the presence of the notch 109, thereby enabling the first open edge 105 and the second open edge 106 to better fit the surface of the copper wire, increasing the contact area with the copper wire, thereby improving the stability of the electrical conductivity and the stability of the connection between the copper wire and the second part 103, therefore, this design ensures the high reliability of the current terminal in electrical connection;

[0033] As shown in the example, Figure 1 the barrier part 102 is provided between the first part 101 and the second part 103, and the three are integrally formed, all of which are made of copper, the barrier part 102 is mostly disc-shaped to separate the first and second parts, and facilitate the installation of the current terminal;

[0034] As shown in the example, Figure 1 , Figure 2 the second part 103 is provided with a thread 104 on the outer surface of one end of the barrier part 102, the thread 104 provided on the surface of the second part is one of the ways to fix the current terminal, such as the connection mode using the thread structure when assembling with the electrical relay and the integrated switch lamp;

[0035] As shown in the example, Figure 1As shown, the second part 103 is provided with a notch 103b near the interaction end 107. The notch 103b is arranged to make the deformation range of the first open edge 105 and the second open edge 106 concentrate on the notch and the notch 103b when being pressed, so that the original shape of the first open edge 105 and the second open edge 106 is better maintained, and the copper wire is pressed to make the copper wire and the first open edge 105 and the second open edge 106 have a larger contact surface area after being pressed, so as to improve the reliability of the electrical connection of the current terminal and the copper wire connection.

[0036] As shown in the example, Figure 2 , Figure 3 the first open edge 105 or / and the second open edge 106 is provided with a notch 109 near the interaction end 107. In this embodiment, the first open edge 105 is provided with a notch 109 near the interaction end 107, so that the first open edge 105 is easily pressed, or the second open edge 106 is provided with a notch 109 near the interaction end 107. In these two cases, only one open edge is easily pressed, which is suitable for terminals limited by space, such as any end of the first or second open edge being blocked, or the first open edge 105 and the second open edge 106 are provided with notches 109 near the interaction end 107, so as to better wrap the copper wire.

[0037] As shown in the example, Figures 1-4 the first notch edge 109a and the second notch edge 109b of the notch 109 intersect, and the rack 108 is distributed on the first open edge 105 and the second open edge 106. One end of the rack 108 is near the end of the second part 103, and the other end is near the notch 103b. The rack 108 on the first open edge 105 is staggered with the rack 108 on the second open edge 106. The staggered racks 108 are beneficial to the all-around grabbing of the copper wire surface, and the staggered positions of the racks 108 make the first open edge 105 and the second open edge 106 press the copper wire more deeply and firmly.

[0038] The first notch edge 109a and the second notch edge 109b of the notch 109 intersect, and as shown in the example, Figure 3 the intersection has a round chamfer. The notch 109 is arranged to make the first and second open edges deform when being pressed, and the first notch edge 109a and the second notch edge 109b gradually approach each other to coincide. The chamfer is arranged to make the first and second open edges bend more evenly when being pressed.
