[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Embodiment 1

[0027] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. Without conflict, the various embodiments and the various features in the embodiments described below can be combined with each other.

[0028] Please refer to Figures 1 to 5 As shown, an embodiment of the present utility model provides a connecting wire for a key, which includes a first terminal 1 and a second terminal 2, and at least two enameled wires 3 or rubber-coated wires electrically connected between the first terminal and the second terminal; a shielding layer 4 is coated outside the wires; a wear-resistant layer 5 is coated outside the shielding layer 4. By introducing the shielding layer 4 and the wear-resistant layer 5, it aims to solve the problems of electromagnetic interference and durability existing in traditional key connecting wires. Specifically, by adding a shielding layer outside the enameled wire 3 or the rubber-coated wire 3, each wire is relatively independent; through the above shielding layer 4, external electromagnetic interference can be effectively shielded, ensuring the stability and accuracy of signal transmission. Among them, the above shielding layer 4 is usually made of a metal material and can form a Faraday cage effect to prevent the intrusion or leakage of electromagnetic waves, thereby improving the purity of the signal and the anti-interference ability of the system; by coating another wear-resistant layer 5 outside the shielding layer 4, the mechanical strength and anti-wear performance of the connecting wire are significantly improved. The wear-resistant layer 5 can protect the internal structure from external physical damage, such as friction, pulling, etc., extend the service life of the connecting wire, and reduce the frequency of maintenance and replacement.

[0029] Embodiment 2

[0030] An embodiment of the present utility model provides a connecting wire for a key. Refer to Figures 2 to 4 As shown, an orientation mark 6 is provided on the first terminal 1 and / or the second terminal 2.

[0031] The above orientation mark 6 enables accurate alignment during installation or replacement, avoiding signal abnormalities or equipment damage caused by incorrect insertion or wrong direction, and improving the installation efficiency and accuracy. For example, in some systems with a large number of circuits, specifically in automotive electronic systems, it ensures the correct connection of various function keys to the control module and avoids system failures caused by wrong directions.

[0032] As a preferred embodiment, the wear-resistant layer 5 is acetate cloth. As the wear-resistant layer 5, acetate cloth not only has good wear resistance but also has certain chemical resistance, is suitable for use under various environmental conditions, and improves the environmental adaptability of the connecting wire. Especially in the chemical industry, the button connecting wire needs to work in an environment with corrosive gases or liquids for a long time, and the use of acetate cloth extends the service life of the connecting wire.

[0033] As a preferred embodiment, the first terminal 1 and the second terminal 2 are multi-core terminals, which are electrically connected through multiple wires 3; and at least the surfaces of the wires 3 on the outermost sides have different colors from the surfaces of other wires. The multi-core terminals can transmit more signals, and the color distinction facilitates the identification of lines with different functions, simplifies the installation and maintenance processes, and reduces the risk of incorrect connection. For example, in complex electronic devices where multiple lines need to work simultaneously, color coding helps with quick identification and connection.

[0034] As a preferred embodiment, multiple wires 3 are twisted and arranged at their positions within the shielding layer 4. As Figure 5 shown, the wires 3 are cross-connected to the terminals. By twisting the wires, electromagnetic interference can be further reduced, the stability and transmission quality of the signal can be improved, and at the same time, the flexibility and tensile strength of the cable can be enhanced.

[0035] As a preferred embodiment, the first terminal 1 and the second terminal 2 are plastic housings, and the surfaces of the conductors connected inside them have a tin plating layer. The plastic housings provide additional insulation and protection, and the tin plating layer enhances the antioxidant and electrical conductivity of the conductors, extending the service life of the connection terminals. For example, the above-mentioned first terminal 1 can be a plastic housing terminal of PH-14P, and the above-mentioned second terminal 2 can be a terminal of DF14-6P or 1.25-7P; in outdoor electronic devices, such as the control panel of a solar power generation system, the plastic housings and the tin plating layer can resist the erosion of harsh weather.

[0036] As a preferred embodiment, the wire is a wire 3 of UL2651 standard specification. Using UL2651 standard wires ensures the electrical performance and safety of the wires, facilitates compatibility with international standard devices, and reduces design and production costs; for example, in parts that require high safety and standardization, UL2651 standard wires meet this requirement.

[0037] As a preferred embodiment, as Figure 2 and Figure 4 shown, one side of the second terminal 2 is provided with a buckle 7; through the above-mentioned buckle 7, the connection and disconnection processes are simplified, facilitating quick installation and disassembly, and improving the maintenance efficiency. Especially in scenarios that require frequent plugging and unplugging, such as game console controllers, the buckle design enables users to quickly connect and disconnect the device.

[0038] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other. Although the optional embodiments of the embodiments of the present invention have been described, once those skilled in the art know the basic creative concept, additional changes and modifications can be made to these embodiments. Therefore, the appended claims are intended to be interpreted to include the optional embodiments as well as all changes and modifications that fall within the scope of the embodiments of the present invention.

[0039] Finally, it should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that an article or terminal device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such an article or terminal device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the article or terminal device including the element.

[0040] The technical solutions provided by the present invention have been introduced in detail above. Specific examples are used in this text to elaborate on the principles and implementation manners of the present invention. At the same time, for those of ordinary skill in the art, based on the principles and implementation manners of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation on the present invention.
