Technical Field
[0001] Embodiments of this disclosure relate to the field of manufacturing technology, and more specifically to three-color extruded products with markings. Background Technology
[0002] With the popularization and widespread use of electronic products, all kinds of electronic products are emerging. This has led to increasingly diverse requirements for the electronic components installed in them, in order to adapt to different application scenarios.
[0003] However, the inventors discovered that as the conductive components produced in the factory become increasingly diverse, there are often products with similar sizes and shapes, or products with the same or similar sizes and shapes but different conductive materials. This often makes it difficult to distinguish them during subsequent production, requiring operators to manually inspect and differentiate them, thus affecting production efficiency. Utility Model Content
[0004] The summary section of this disclosure is intended to provide a brief overview of concepts that will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions. Some embodiments of this disclosure propose a three-color extruded product with an identification feature to address one or more of the technical problems mentioned in the background section above.
[0005] Some embodiments of this disclosure provide a three-color extruded product with markings, comprising: a first conductive layer made of a conductive material, forming the inner surface of the three-color extruded product, wherein a through hole extending along the length direction is formed inside the three-color extruded product, penetrating both ends of the three-color extruded product; a second conductive layer made of a conductive material, forming the outer surface of the three-color extruded product; an intermediate layer made of an insulating material, located between the first conductive layer and the second conductive layer; and a marking symbol marked on the outer surface of the three-color extruded product excluding the two end faces, for marking purposes, wherein the color of the marking symbol is different from the color of the second conductive layer.
[0006] In some embodiments, the identifier includes at least one of the following: identifier line, identifier graphic, identifier number, and identifier letter.
[0007] In some embodiments, the identifier is an identifier line that extends along the length of the three-color extruded product and marks both ends of the three-color extruded product.
[0008] In some embodiments, the intermediate layer has a plurality of through holes formed along the length of the three-color extruded product, and the plurality of through holes are uniformly arranged on the circumference of the intermediate layer.
[0009] In some embodiments, the via penetrates the intermediate layer in the thickness direction, wherein one side of the via contacts the outer layer of the first conductive layer, and the other side contacts the inner layer of the second conductive layer.
[0010] In some embodiments, the three-color extruded product is cylindrical, and the through hole is a cylindrical through hole; the diameter of the through hole is 0.9 mm, the diameter of the first conductive layer is 2.9 mm, the diameter of the intermediate layer is 5 mm, the diameter of the second conductive layer is 7 mm, and the length of the three-color extruded product is 6 mm, wherein the dimensional error is ±0.1 mm.
[0011] In some embodiments, the outer surface of the three-color extruded product is coated with an anti-reflective coating.
[0012] The various embodiments of this disclosure have the following beneficial effects: The three-color extruded products with markings in some embodiments of this disclosure facilitate the differentiation of similar products. Specifically, markings are made on the outer surface of the three-color extruded product, excluding both end faces, i.e., on the outer layer of the second conductive layer. The color of the markings is different from the color of the second conductive layer. Thus, for similar products, such as those with similar shapes and sizes or different conductive materials, operators can quickly and intuitively distinguish them by observing whether the markings are present, eliminating the need for product testing and measurement. This not only improves the efficiency of differentiating similar products and overall production efficiency but also significantly reduces the defect rate caused by incorrect installation of similar products. Furthermore, during subsequent product installation inspections, the markings on the product allow for intuitive confirmation of the correct product model and size, eliminating the need for random sampling. This also helps improve verification efficiency. Attached Figure Description

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Figure 1 Schematic diagrams of the structure of some embodiments of the three-color extruded products with markings of this disclosure are shown. For example... Figure 1 The three-color extruded product disclosed herein may include a first conductive layer 11, a second conductive layer 12, and an intermediate layer 13. As shown in the figure, a through-hole extending along the length direction is formed inside the three-color extruded product, penetrating both ends of the product. Here, the first conductive layer 11 can constitute the inner surface of the three-color extruded product; that is, the inner layer of the first conductive layer 11 is the sidewall of the through-hole. The second conductive layer 12 can constitute the outer surface of the three-color extruded product; that is, the outer layer of the second conductive layer 12 is the outer surface of the three-color extruded product. The intermediate layer 13 can be located between the first conductive layer 11 and the second conductive layer 12. The first conductive layer 11 and the second conductive layer 12 can be made of conductive materials, while the intermediate layer 13 can be made of insulating materials, such as rubber or silicone.
[0023] Furthermore, the three-color extruded product of this disclosure is also provided with identification symbol 14. Identification symbol 14 can be marked on the outer surface of the three-color extruded product, excluding the two end faces, for identification purposes. It is understood that, for ease of observation by operators, the color of the identification symbol is usually different from the color of the second conductive layer. As an example, the identification symbol can be red.
[0024] In this embodiment, identification symbols are marked on the outer surface of the three-color extruded product, excluding both end faces, i.e., on the outer layer of the second conductive layer. The color of these symbols differs from the color of the second conductive layer. This allows operators to quickly and intuitively distinguish between similar products, such as those with similar shapes and sizes or different conductive materials, simply by observing the presence of these symbols, eliminating the need for product inspection and measurement. This not only improves the efficiency of distinguishing similar products and overall production efficiency but also significantly reduces the defect rate caused by incorrect installation of similar products. Furthermore, during subsequent product installation inspections, the identification symbols on the product allow for a direct determination of whether the installed product model and size are correct, without the need for random sampling. This also helps improve verification efficiency.
[0025] It should be noted that the style and position of the aforementioned identifier 14 can be set according to actual needs. As an example, identifier 14 may include at least one of the following: a marker line, a marker graphic, a marker number, a marker letter, etc. The marker line here can be a solid line, a dashed line, a curve, etc. Furthermore, the identifier can be placed near one or both ends of the three-color extruded product, or it can be placed in the middle of the three-color extruded product.
[0026] It should be noted that the layers of a three-color extruded product are typically produced using an automated extrusion die. That is, the die continuously extrudes each layer in a production sequence, resulting in a strip-shaped three-color extruded semi-finished product. This strip-shaped semi-finished product is then cut to obtain individual three-color extruded products of the desired length. Figure 3 As can be seen, the cut three-color extruded products are usually very small components, and the quantity is relatively large, so manually marking the symbols would be time-consuming and laborious.
[0027] In some embodiments, to achieve automated production of identification marks, the identification marks in this disclosure can be marking lines. These marking lines can extend along the length of the three-color extruded product and be marked at both ends. That is, the marking lines can be straight lines or dashed lines. This allows the marking of the marking lines to be completed during the production of the three-color extruded semi-finished product. Specifically, a marking device can be installed during the movement of the strip-shaped semi-finished product. After passing through the marking device, the marking lines can be marked on the outer surface of the product. This ensures that each product has marking lines after subsequent cutting. This not only achieves automated marking of identification marks, reducing manual operation and improving production efficiency, but also minimizes modifications and impacts on existing equipment and production processes.
[0028] In some embodiments, the intermediate layer 13 of the three-color extruded product with identification features disclosed herein may also be formed with a plurality of (at least two) through holes 15. For example... Figure 2 and 3 As shown, these through-holes 15 also extend through both ends of the three-color extruded product along its length, and these through-holes are evenly distributed on the circumference of the intermediate layer 13. As an example, such as... Figure 2 As shown, four through holes 15 can be set at equal intervals. Alternatively, three or two through holes can be set.
[0029] Understandably, the shape of the through-hole 15 can also be set according to actual needs. These through-holes are usually formed directly during the production of the intermediate layer 13. In some embodiments, to simplify the device structure, such as Figure 2 As shown, the through-hole 15 penetrates the intermediate layer 13 in the thickness direction. One side of the through-hole 15 contacts the outer layer of the first conductive layer 11, and the other side contacts the inner layer of the second conductive layer 12. That is, the first conductive layer 11, the second conductive layer 12, and the intermediate layer 13 together form the through-hole 15.
[0030] It should be noted that the conductive elements in existing three-color extruded products typically only have a central through-hole, with the other layers being solid. After installation, the two end faces of the product are subjected to compression along its length. Because existing three-color extruded products only create a accommodating space in the relatively small central through-hole, the overall hardness of the product is relatively high, especially along the compressed length. This results in a shorter compressible distance along the length of the product and a larger reaction force after compression. This significantly reduces the applicable scenarios and scope of the product, while increasing the manufacturing precision requirements for the product and its installation location. Otherwise, problems may arise such as the product being too long to install, or the large reaction force after installation preventing secure fixation.
[0031] Based on this, the three-color extruded product of this disclosure can form more accommodating space by forming through holes 15 in the intermediate layer. This allows the product to move not only towards the central through hole but also towards these through holes when pressure is applied at both ends. This improves the product's elasticity, i.e., it increases the product's retractable distance along its length. This, in turn, expands the product's applicable scenarios and scope, and reduces the manufacturing precision requirements for the product and its installation location. Furthermore, these through holes reduce the internal extrusion pressure of the product under pressure, thereby mitigating the reaction force generated after pressure.
[0032] It is understood that the shape and size of the three-color extruded product are not limited. In some embodiments, as shown in the figure, the three-color extruded product can be cylindrical, and the through hole is a cylindrical through hole. In this case, as... Figure 3As shown, the diameter of the through hole can be 0.9 mm; the diameter of the first conductive layer can be 2.9 mm; the diameter of the intermediate layer can be 5 mm; the diameter of the second conductive layer can be 7 mm; and the length of the three-color extruded product can be 6 mm. The tolerance for each dimension can be ±0.1 mm. Furthermore, the coaxiality tolerance of the through hole can be 0.1 mm. The coaxiality tolerance of the outer cylindrical surface of the three-color extruded product can also be 0.1 mm.
[0033] In some embodiments, at least one end of the three-color extruded product with identification features disclosed herein has a connecting structure. The shape and dimensions of this connecting structure are adapted to the fixing structure at the installation location. Furthermore, this connecting structure is obtained directly during cutting, i.e., it is directly cut during the process of cutting the strip-shaped three-color extruded semi-finished product to a predetermined length. The connecting structure can be configured according to actual needs. As an example, for ease of cutting, the connecting structure can be at least one groove that extends through the end face, i.e., cut from one side to the other, forming at least one groove. The groove can be a strip-shaped groove or a curved groove. The fixing structure can be at least one protrusion.
[0034] When installing the three-color extruded product, the end with the connecting structure can be oriented towards the installation position, and the protrusion can be embedded into the groove. The connecting structure's restraining effect ensures the accuracy of the installation position of the three-color extruded product and prevents positional deviation. Furthermore, this connecting structure increases the contact area, improves the reliability of the fixation, and enhances signal connectivity.
[0035] Furthermore, the groove can extend towards the location of the indicator. This allows the indicator to serve as a guide for installation direction. The indicator allows for quick and intuitive determination of the groove's orientation, aligning it with the protrusion at the installation position and enabling rapid installation without the need for repeated rotations to adjust the installation location.
[0036] The above-described optional embodiments, as an inventive point of this disclosure, solve the technical problem of "the installation position of three-color extruded products is prone to displacement and the fixation is not secure." It is understood that the two ends of existing three-color extruded products are usually flat, and one end is typically bonded to the installation position using adhesive. This fixing method is prone to displacement before the adhesive is completely dry, resulting in inaccurate installation. Furthermore, because of the flat structure, the product only experiences a unidirectional fixing force after fixing. However, during use, due to the product's extrusion deformation, it may be subjected to forces from multiple directions. This makes the fixing end face, which only experiences a unidirectional fixing force, prone to cracking.
[0037] Furthermore, conductive material is typically sprayed onto both ends of three-color extruded products. Additionally, an anti-reflective coating can be sprayed onto the outer surface of three-color extruded products, such as... Figure 3 The Ag coating shown is an example of a coating that utilizes the principles of light refraction and scattering to reduce light reflection.
[0038] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
