[0024] The present utility model will be further described below in conjunction with the accompanying drawings.

[0025] As Figure 1 and Figure 2 shown, the anti-mixing cap for terminal posts of an embodiment of the present utility model includes a cylinder body 1 and an identification piece 2. As Figure 3 and Figure 4 shown, a first opening 100 is provided at the bottom of the cylinder body 1, a second opening 200 is provided at the top of the cylinder body 1, an opening 400 connected to the first opening 100 is provided on the side surface of the cylinder body 1, the identification piece 2 is pasted on the top of the cylinder body 1, a third opening 300 is opened on the identification piece 2, and the second opening 200 is aligned with the third opening 300.

[0026] The first opening 100 opened at the bottom of the cylinder body 1 enables the cylinder body 1 to be sleeved outside the terminal post 3 and wrap the terminal post 3. By pasting the identification piece 2 printed with different information on the top of the cylinder body 1, each terminal post 3 can be visually marked, so that the operator can quickly find the required terminal post 3 for operation or maintenance. The second opening 200 opened at the top of the cylinder body 1 is aligned with the third opening 300 opened on the identification piece 2, enabling the operator to conveniently test the terminal post 3 inside the cylinder body 1 through the second opening 200 and the third opening 300. The opening 400 serves as a wire passing hole for the wire (not shown in the figure) connected to the terminal post 3 to pass through. The anti-mixing cap for terminal posts in this embodiment corresponds to the terminal post 3 one by one and is very flexible to use. Regardless of the number and arrangement of the terminal posts 3, all terminal posts 3 can be clearly and visually identified. The cylinder body 1 and the identification piece 2 are connected by pasting. The cylinder bodies 1 of the same size terminal posts 3 can be universal, thus facilitating the use by the staff.

[0027] As Figure 5As shown in the figure, the identification piece 2 includes a short side 21, a semi-circular side 22 and two long sides 23. The short side 21 is arranged opposite to the semi-circular side 22, and the two long sides 23 are arranged opposite to each other. The two ends of the short side 21 are connected to the first ends of the long sides 23, and the two ends of the semi-circular side 22 are connected to the second ends of the long sides 23. The top of the cylinder body 1 is circular, and the semi-circular side 22 is flush with the top edge of the cylinder body 1. By setting the identification piece 2 in this shape, while ensuring that the identification piece 2 can fully contact the top of the cylinder body 1, the area of the identification piece 2 is reduced, and the semi-circular side 22 is flush with the top edge of the cylinder body 1 to facilitate the accurate positioning of the identification piece 2.

[0028] Furthermore, the center of the third opening 300 coincides with the center of the circle corresponding to the semi-circular side 22. When the semi-circular side 22 is flush with the top edge of the cylinder body 1, the third opening 300 and the second opening 200 will be automatically aligned, so that there is no need to separately adjust the position of the identification piece 2, reducing the pasting difficulty of the identification piece 2.

[0029] As Figure 3 and Figure 4 shown in the figure, an arched extension part 14 is provided on one side of the cylinder body 1, and the extension part 14 is arranged along the edge of the opening 400. If the extension part 14 is not provided, the opening 400 will significantly weaken the structural strength of the cylinder body 1 and is prone to deformation. By providing the extension part 14 at the opening 400, it can play a certain strengthening role and improve the anti-deformation ability of the cylinder body 1.

[0030] Furthermore, the thickness of the extension part 14 is the same as the thickness of the cylinder body 1. In this embodiment, both the cylinder body 1 and the identification piece 2 are made of plastic, such as polyethylene or polypropylene, so that the terminal post anti-mixing cap has good insulation. The cylinder body 1 is made by an integral injection molding process, with low manufacturing difficulty and cost.

[0031] As Figure 3 and Figure 4 shown in the figure, the cylinder body 1 includes a main body part 11, a reduced-diameter part 12 and a connecting part 13. The reduced-diameter part 12 is arranged between the main body part 11 and the connecting part 13. The outer diameter of the reduced-diameter part 12 is smaller than the outer diameter of the main body part 11, and the outer diameter of the connecting part 13 is larger than the outer diameter of the reduced-diameter part 12. The first opening 100 is opened at one end of the main body part 11 away from the reduced-diameter part 12, the second opening 200 is opened on the connecting part 13, and the identification piece 2 is connected to one end of the connecting part 13 away from the reduced-diameter part 12. By providing the reduced-diameter part 12, an annular groove is formed in the upper part of the cylinder body 1, which is convenient for fingers to grasp the cylinder body 1 and is not prone to slipping and other situations. In addition, by providing the reduced-diameter part 12, it can also play a strengthening role in the overall structure of the cylinder body 1, making the cylinder body 1 less prone to deformation.

[0032] Further, the height of the main body portion 11 is greater than that of the diameter-changing portion 12, and the height of the diameter-changing portion 12 is greater than that of the connecting portion 13, that is, the heights of the main body portion 11, the diameter-changing portion 12, and the connecting portion 13 decrease in sequence. The main body portion 11 accommodates most of the terminal post 3 and also needs to be provided with an opening 400, so it occupies most of the volume of the cylinder 1. The main functional area of the connecting portion 13 is its top, so it does not require a large volume and only a relatively thin thickness can meet the requirements.

[0033] In this embodiment, the bottom of the main body portion 11 is flush with the bottom of the extension portion 14, so that the cylinder 1 can be stably placed on the terminal post 3 and is not likely to become loose.

[0034] In this embodiment, the aperture of the first opening 100 is larger than that of the second opening 200. The whole of the terminal post 3 needs to enter the interior of the cylinder 1 through the first opening 100, so the aperture of the first opening 100 is larger. The second opening 200 only needs to allow the test tool to pass through and contact the terminal post 3, so it does not require a large aperture. In addition, a second opening 200 with a larger aperture will also make the bottom area of the connecting portion 13 smaller, which is not conducive to pasting the identification piece 2. Since the second opening 200 and the third opening 300 are used in combination, the aperture of the second opening 200 is the same as that of the third opening 300.

[0035] Although the present invention has been described with reference to the preferred embodiments, various modifications can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
