[0036] 200. Charging cable. Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] In the existing technology, in order to increase the magnetic attraction effect, multiple magnets need to be designed for adsorption in some magnetic headphones, which is not conducive to the miniaturization and lightweight design of headphones and charging cables.

[0039] To resolve the above technical issues, please refer to Figure 1 This application proposes an earphone assembly, including two electrical structures, one of which is an earphone 100, and the other of which is a charging cable 200. The spring pin 120 in the earphone 100 can be electrically connected to the spring pin 120 in the charging cable 200.

[0040] Among them, the earphone 100 is a wireless earphone, such as a wireless over-ear earphone, a wireless neckband earphone, or a wireless sports earphone, which requires a charging cable 200 for charging.

[0041] It is understandable that when the charging cable 200 is electrically connected to the earphone 100, the two can not only transmit electrical energy but also transmit signals.

[0042] The following will be combined with the appendix Figures 2-3 The electrical structure is further described as including a main body 110, a separator 130, and multiple spring pins 120.

[0043] The main body 110 is the basic part of the electrical structure, providing physical support and fixation for other components (such as spring pin 120 and separator 130). The main body 110 can protect the internal components from the influence of the external environment (such as dust, moisture, and mechanical impact). The main body 110 may include circuit boards, microphones, pickups and other audio output and audio input electrical components or auxiliary input and output audio electrical components.

[0044] Multiple spring pins 120 are electrically connected to the main body 110, specifically to the circuit board in the main body 110. The flexible circuit board can serve as a "bridge" for electrical transmission. The flexible circuit board allows for better placement of the spring pins 120 and the circuit board, facilitating the miniaturization design of the earphone 100 or charging cable 200. Furthermore, multiple spring pins 120 can simultaneously contact the target, forming a multi-point electrical connection, which improves the stability and reliability of the connection.

[0045] When the spring pin 120 on the earphone 100 is connected to the spring pin 120 on the charging cable 200, the spring pin 120 plays the role of signal transmission and charging conductivity. It can be understood that the spring pin 120 can be made of copper alloy or stainless steel. When the spring pin 120 is made of copper alloy, it can be made of beryllium copper, phosphor bronze or brass, which have excellent conductivity. When the spring pin 120 is made of beryllium copper or phosphor bronze, the spring pin 120 also has excellent elasticity. When the spring pin 120 is made of stainless steel, it has good corrosion resistance and mechanical strength.

[0046] In one embodiment, the spring pin 120 can also be made of ferritic stainless steel, i.e., 430 stainless steel. In this way, the spring pin 120 can be magnetic. When the earphone 100 is electrically connected to the charging cable 200, the magnetic spring pin 120 on the earphone 100 can generate an attraction with the magnetic spring pin 120 on the charging cable 200, automatically adsorbing and aligning. While the spring pin 120 is magnetically adsorbed, it achieves electrical contact and completes the transmission of electrical energy or signals.

[0047] Magnetic adsorption allows the spring pins 120 to be aligned quickly and accurately without manual adjustment. Users only need to bring the earphone 100 close to the charging cable 200, and the magnetic force will automatically complete the connection. The operation is simple, and the magnetic adsorption ensures a tight contact between the spring pins 120, reducing the risk of poor contact or disconnection.

[0048] It is understandable that the spring pins 120 on the earphone 100 and the spring pins 120 on the charging cable 200 have opposite or different polarities.

[0049] The separator 130 is disposed on the main body 110, and at least a portion of the separator 130 is located between the plurality of spring pins 120 to achieve insulation isolation between the plurality of spring pins 120. That is, the separator 130 prevents short circuit or leakage of current and ensures electrical safety. In addition, the separator 130 can prevent direct contact between the spring pins 120 to avoid mechanical wear or damage.

[0050] It is understandable that when the charging cable 200 and the earphone 100 are connected, in order to prevent the charging cable 200 and the earphone 100 from easily falling off, the charging cable 200 and the earphone 100 can be snapped together or magnetically attracted. In this embodiment, the charging cable 200 and the earphone 100 are magnetically attracted for illustrative purposes.

[0051] The separator 130 includes a magnet and an insulating layer disposed on the surface of the magnet. The insulating layer can be an epoxy resin insulating layer, which can be coated or plated to cover the outer surface of the magnet. The insulating layer isolates the magnet from external electrical components, ensuring that the current can only flow in the designed path and avoid short circuits or leakage. In this way, short circuits between the spring pin 120 and the magnet can be avoided.

[0052] The magnet provides magnetic attraction, and the polarity of the magnet in the earphone 100 is opposite to that of the magnet in the charging cable 200. Thus, when the charging cable 200 and the earphone 100 are electrically connected, the magnet in the earphone 100 is magnetically connected to the magnet in the charging cable 200, thereby ensuring the stability and reliability of the electrical connection between the charging cable 200 and the earphone 100.

[0053] By using magnetic adsorption, not only is the use of mechanical locks and other components reduced, simplifying design and use, but it can also automatically align within a certain range, reducing the requirements for precise operation.

[0054] In the embodiments of this application, please refer to 4-5. The side of the magnet facing away from the main body is the magnetic attraction surface. The magnetic attraction surface includes at least one first magnetic region 130b and at least one second magnetic region 130c. The polarities of the first magnetic region 130b and the second magnetic region 130c are opposite.

[0055] The first magnetic region 130b can be provided as one or more, and the second magnetic region 130c can also be provided as one or more. In this embodiment, it is exemplarily described that both the first magnetic region 130b and the second magnetic region 130c have one.

[0056] The adjacent first magnetic region 130b and second magnetic region 130c N / S poles are arranged alternately on the magnetic attraction surface to form a dense magnetic field loop. The magnetic field strength is significantly higher than that of a single polarity design, and the adsorption force can be increased by 30%-50%.

[0057] The alternating polarity design allows the charging cable 200 and earphone 100 to automatically correct to the only correct direction when they are magnetically attracted, avoiding poor contact caused by reverse attraction. This can play a certain role in "foolproofing". The bipolar magnetic field design can reduce the size of the magnet under the same attraction force, directly reducing the weight and space occupied by the device, thus facilitating the miniaturization and lightweight design of the earphone 100 and the charging cable 200.

[0058] To reduce manufacturing steps and improve the installation efficiency of the earphone 100 and charging cable 200, in this embodiment, the magnet in the separator 130 is integrally formed. This allows the user to magnetize the magnet, enabling the magnetic attraction surface of the magnet facing away from the main body to pass through the first magnetic region 130b and the second magnetic region 130c, which have opposite polarities.

[0059] Optionally, the first magnetic region 130b and the second magnetic region 130c have the same area. The polar regions with equal areas achieve a higher magnetic attraction strength within a limited volume through the magnetic field superposition effect, reducing the need to increase the volume of the magnet to enhance the magnetic force.

[0060] The N / S poles of equal area are arranged alternately to form a symmetrical magnetic field distribution, avoiding the attraction and displacement caused by excessive magnetic force on one side. This ensures that the charging cable 200 or earphone 100 is subjected to uniform force when in contact with the device. In addition, the uniform magnetic field avoids excessive local magnetic attraction force squeezing the contact surface, reducing the risk of mechanical wear on the spring pin 120 or the interface, and extending its service life.

[0061] Optionally, multiple spring pins 120 are symmetrically distributed about the midline connecting the first magnetic region 130b and the second magnetic region 130c. The symmetrical layout ensures that the contact points of the spring pins 120 are evenly distributed in the N / S pole magnetic field, ensuring that the magnetic attraction force on each spring pin 120 is consistent, avoiding differences in contact pressure due to uneven magnetic force, and improving the overall connection stability.

[0062] Secondly, during insertion, removal, or external impact, the symmetrical spring pins 120 uniformly transfer stress to the N / S pole magnet support area, avoiding local stress concentration that could lead to structural deformation or cracking. Furthermore, the symmetrical layout makes the contact frequency and wear degree of each spring pin 120 similar, preventing premature failure of a single spring pin 120 and extending the overall interface lifespan.

[0063] In some embodiments, the thickness of the insulating layer is h, where h satisfies: 0.02mm ≤ h ≤ 0.04mm, and h can be 0.02mm, 0.03mm, 0.04mm, or any two of the above values.

[0064] By ensuring that h is within the aforementioned range, it is possible to prevent short circuits between the magnet and the spring pin 120. This provides sufficient insulation without significantly weakening the magnetic force. Furthermore, the insulation layer can isolate the magnetic material from the external environment (such as moisture and corrosive substances), extending the service life of the magnetic material.

[0065] In addition, the insulation layer has a moderate thickness, which meets the performance requirements while reducing the amount of material used and lowering costs.

[0066] In some embodiments, please refer to Figure 6 Multiple spring pins 120 are inserted through the separator 130, meaning that the spring pins 120 can be partially hidden inside the separator 130, maintaining the cleanliness and aesthetics of the equipment's appearance.

[0067] By partially concealing the spring pin 120 inside the separator 130, efficient connection can be achieved within a limited space, making the earphone 100 and charging cable 200 more compact, which facilitates the miniaturization and lightweight design of the earphone 100 and charging cable 200.

[0068] Furthermore, the separator 130 is provided with a plurality of clearance grooves 130a, and a plurality of spring pins 120 are respectively inserted into the plurality of clearance grooves 130a. The plurality of clearance grooves 130a are spaced apart. The spaced arrangement of the clearance grooves 130a is achieved by separating each spring pin 120 independently through the material of the separator 130, so as to avoid short circuits between spring pins 120 due to contact or arc discharge. The material of the separator 130 around the clearance grooves 130a can provide additional electrical isolation to ensure safety under high voltage or high current applications.

[0069] Each spring pin 120 is individually inserted into the clearance groove 130a and is independently fixed by the support of the groove wall, which reduces mutual interference or displacement between spring pins 120 and ensures the stability of spring pins 120. The clearance grooves 130a arranged at intervals can evenly distribute external mechanical stress (such as vibration and collision) to each spring pin 120, avoiding structural deformation caused by stress concentration.

[0070] In addition, each clearance groove 130a provides precise positioning space for the corresponding spring pin 120, ensuring that the contact points of the spring pin 120 in the earphone 100 and the spring pin 120 in the charging cable 200 are precisely aligned, thereby improving the reliability of the connection.

[0071] In one embodiment, the body 110 defines a mounting cavity 110a, at least a portion of the separator 130 is located within the mounting cavity 110a, a portion of the spring pin 120 is located within the mounting cavity 110a, and the remaining portion of the spring pin 120 is located outside the mounting cavity 110a.

[0072] That is, the separator 130 can be entirely located inside the mounting cavity 110a, or only partially located outside the mounting cavity 110a. For example, in the earphone 100, the separator 130 is located inside the mounting cavity 110a. In the charging cable 200, the separator 130 is partially located inside the mounting cavity 110a and partially located outside the mounting cavity 110a.

[0073] The spring pin 120 located outside the mounting cavity 110a in the earphone 100 can quickly align with the spring pin 120 of the charging cable 200 located outside the mounting cavity 110a, thereby achieving a conductive connection. That is, only the functional contact part of the spring pin 120 is allowed to be exposed, while the remaining conductive parts are wrapped inside the cavity, reducing the possibility of accidental contact or accidental short circuit.

[0074] The separator 130 can be combined with the insulating plate within the mounting cavity 110a to form a double insulation barrier, further preventing the risk of leakage or short circuit.

[0075] Please return to the reference. Figure 3 and combined Figure 6 When the electrical structure is an earphone 100, the main body 110 includes a body 111 and a connector housing 112. The connector housing 112 is located at the end of the body 111 and defines an installation cavity 110a with the body 111. The modular design of the first outer shell 111 and the second outer shell 112 facilitates production and maintenance.

[0076] The connector housing 112 includes a mounting plate 1121 and a limiting plate 1122. The mounting plate 1121 and the limiting plate 1122 can be an integrally formed structure, thereby reducing the construction process. The mounting plate 1121 and the limiting plate 1122 can be installed on the body 111 by means of snap-fit ​​or screws, etc., which is not limited here.

[0077] The limiting plate 1122 is located on the side of the mounting plate 1121 facing away from the mounting cavity 110a. The mounting plate 1121 and the mounting plate 1122 together form the limiting cavity 112a. When the spring pin 120 on the earphone 100 is used to make electrical connection with the spring pin 120 of the charging cable 200, the limiting cavity 112a is used to accommodate part of the magnet in the charging cable 200. The part of the magnet in the charging cable 200 is attached to the inner wall surface of the limiting plate 1122. The attachment and fixation of the magnet ensures that the spring pin 120 of the charging cable 200 and the spring pin 120 of the earphone 100 are always in the best contact position, avoiding poor contact or charging interruption due to displacement.

[0078] The limiting cavity 112a can play a certain guiding role, guiding the charging cable 200 to be inserted correctly, avoiding the user from inserting it backwards or misaligning it, thus improving the convenience of use. At the same time, the inner wall of the limiting plate 1122 is in contact with the charging cable 200, which may play a fixing role, reducing the risk of the charging cable 200 falling off due to pulling during use.

[0079] The design of the limiting cavity 112a helps to fix the charging cable 200, prevent it from loosening during use, and improve the reliability of the connection. The magnetic contact and fixation ensure that the spring pin 120 of the charging cable 200 and the spring pin 120 of the earphone 100 are always in the optimal contact position, avoiding poor contact or charging interruption due to displacement. In addition, the limiting cavity 112a can also serve as a protective structure to prevent foreign objects from entering and protect the contact points of the conductive spring pin 120 and the charging cable 200.

[0080] On the other hand, some of the magnets in the charging cable 200 are wrapped in the limiting cavity 112a, which makes the overall structure of the earphone 100 component compact, reduces the size of the earphone 100 component, and is suitable for miniaturization design.

[0081] For further information, please refer to [link / reference]. Figure 6The outer peripheral sidewall of the spring pin 120 is provided with a mounting groove 120a, and part of the main body 110 is engaged in the mounting groove 120a.

[0082] The main body 110 can be made of plastic material with a certain degree of elasticity. The main body 110 has an opening to facilitate the insertion of the spring pin 120, which also makes it easy for the spring pin 120 to be attached to the clip. The bottom wall of the mounting groove 120a can be interference-fitted with the main body 110, so that the spring pin 120 is tightly assembled on the earphone 100. This also provides waterproof and dustproof function, reducing the possibility of dust, rainwater and other impurities entering the mounting cavity 110a through the connection between the spring pin 120 and the main body 110.

[0083] In addition, the snap-fit ​​between the mounting groove 120a and the main body 110 forms a mechanical interlock structure to prevent the spring pin 120 from shifting or falling off due to vibration, insertion or removal or external force during use. The snap-fit ​​design increases the contact area between the spring pin 120 and the main body 110, disperses external mechanical stress, and reduces the risk of local deformation.

[0084] The snap-fit ​​design replaces traditional welding or bonding processes, reducing process complexity and improving assembly efficiency. When the spring pin 120 is damaged, it can be directly pulled out from the mounting slot 120a for replacement without damaging the main body 110 structure, thus reducing maintenance costs.
