Description

Technical Field

[0001] The present application relates to the field of earphone tail plugs, and in particular to a Bluetooth earphone tail plug charging stand. Background Art

[0002] With the rapid development of wireless technology, Bluetooth headsets have become a common electronic device in our daily lives due to their convenience and wireless connectivity. Bluetooth headsets are typically electrically connected to a charging station via a tail plug to enable charging. In traditional designs, the conductive terminals of the tail plug typically utilize metal contacts protruding from the surface of the seal. While this design effectively connects to the charging station, it also has some significant drawbacks.

[0003] First, the protruding design of the conductive terminals on traditional headphone tail plugs results in a smaller contact area with the charging dock, making them prone to poor contact. During charging, poor contact can cause the headphones to not charge properly or even cause unstable charging current, impacting their lifespan and charging efficiency. Furthermore, over time, the protruding conductive terminals easily accumulate dust and impurities, further affecting electrical contact performance.

[0004] Secondly, the protruding metal contacts of traditional earphone tail plugs are easily impacted or squeezed during daily use, causing deformation or even damage. When users carry their Bluetooth earphones in a bag or carry them around, the protruding contacts can collide with other objects, causing mechanical damage. Once deformed or damaged, the earphones won't charge properly, impacting the user experience. Utility Model Content

[0034] An embodiment of the present application provides a Bluetooth headset tail plug charging stand, comprising:

[0035] a cylindrical clamping portion;

[0036] a sealing cover, the sealing cover being disposed at one end of the cylindrical clamping portion, the sealing cover having an annular arc surface on a side facing away from the cylindrical clamping portion, the annular arc surface protruding toward the side of the sealing cover facing away from the cylindrical clamping portion, and the central axis a of the annular arc surface coinciding with the central axis b of the sealing cover;

[0037] Conductive terminals, two of which are symmetrically arranged on the cylindrical clamping portion relative to the central axis b of the sealing cover;

[0038] Conductive extension sheets, wherein the two conductive extension sheets are symmetrical with respect to the central axis a of the annular arc surface and are fitted on the sealing cover;

[0039] The conductive extensions correspond one-to-one with the conductive terminals, and the conductive terminals are electrically connected to the conductive extensions. The Bluetooth earphone tail plug charging station provided above is designed with an extended conductive portion electrically connected to the conductive terminals that fits on the annular curved surface, preventing the conductive terminals from being damaged by external forces due to the protruding design. To address the technical shortcomings of the conductive terminals in traditional earphone tail plugs, the annular curved surface design creates a smooth outer surface, reducing the probability of damage to the tail plug due to collisions.

[0040] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0041] See also Figure 1-Figure 7 , an embodiment of the present application provides a Bluetooth headset tail plug charging stand 100, including a cylindrical clamping portion 1, a sealing cover 2, a conductive terminal 3 and a conductive extension piece 4, the sealing cover 2 is arranged at one end of the cylindrical clamping portion 1, and the sealing cover 2 has an annular arc surface 21 on the side away from the cylindrical clamping portion 1, and the annular arc surface 21 protrudes toward the side of the sealing cover 2 away from the cylindrical clamping portion 1, and the central axis a of the annular arc surface 21 coincides with the central axis b of the sealing cover 2. The two conductive terminals 3 are symmetrically arranged on the cylindrical clamping portion 1 relative to the central axis b of the sealing cover 2. The two conductive extension pieces 4 are symmetrical with respect to the central axis a of the annular arc surface 21 and are fitted on the sealing cover 2. The conductive extension piece 4 corresponds one-to-one to the conductive terminal 3 and the conductive terminal 3 is electrically connected to the conductive extension piece 4.

[0042] Specifically, the cylindrical snap-in portion 1 mechanically connects the earphone tail plug to the Bluetooth headset, ensuring a secure connection. The cylindrical structure provides sufficient stability, preventing the earphones from shaking or falling off during charging. This design ensures a secure connection between the tail plug and the Bluetooth headset, thereby improving the stability of the contact between the Bluetooth headset and the tail plug, reducing the possibility of poor contact, and enhancing charging stability and safety. A sealing cap 2, located at one end of the cylindrical snap-in portion 1, seals and protects the internal components. Furthermore, the side facing away from the cylindrical snap-in portion 1 features an annular curved surface 21, which not only aesthetically pleasing but also enhances the fit with the conductive extension sheet 4. The presence of the sealing cap 2 effectively prevents dust and moisture from entering the interior, thereby protecting the conductive components. Furthermore, the annular curved surface 21 optimizes the structural layout of the charging station, making the conductive sheet design more compact and efficient. The annular curved surface 21 is located on the sealing cap 2, with its axis a coinciding with the central axis b of the sealing cap 2, ensuring symmetry and mechanical stability. This curved surface is a key structural feature of the design, providing the contour of the external contact surface. The protruding design of the annular curved surface 21 not only provides a stable reference structure for the conductive extension 4 to fit, but also improves the stability of the electrical connection during charging by optimizing the contact angle and contact area. Furthermore, it reduces the risk of foreign matter accumulation and enhances durability. The conductive terminals 3 are symmetrically arranged on the cylindrical clamping portion 1 relative to the central axis b of the sealing cover 2. They are responsible for transmitting electrical energy and ensuring an efficient and stable electrical connection between the earphones and the charging dock. The symmetrical arrangement of the conductive terminals 3 improves electrical balance and stability during charging, reducing current unevenness or poor contact. Furthermore, the structure of the conductive terminals 3 further optimizes the current transmission path through electrical connection with the conductive extension 4. The conductive extension 4 is symmetrically arranged relative to the central axis a of the annular curved surface 21 and fits snugly on the sealing cover 2, corresponding one-to-one with the conductive terminals 3. The conductive extension 4 extends the conductive contact area, further optimizing the electrical conduction path. By cooperating with the conductive terminals 3, the conductive extension 4 can expand the electrical contact area, thereby enhancing charging stability and efficiency. The snug design also makes the structure more compact, contributing to the miniaturization and aesthetics of the overall device. The conductive terminals 3 are electrically connected to the conductive extension piece 4, forming an efficient conductive loop. This connection ensures stable transmission of power from the charging base to the earphones.

[0043] Furthermore, the "annular arc surface 21" is a specific curved surface, which can generally be understood as an arc surface rotating around a central axis. Specifically, it is an arc in a plane that rotates around the vertical axis of the plane to form a three-dimensional curved surface. Therefore, the annular arc surface 21 presents an annular structure, similar to a smooth semicircle, with a certain degree of curvature. The annular arc surface 21 is symmetrical, and its central axis (such as the central axis a in the above description) is the rotation axis of the entire annular structure. Regardless of the direction from which it is viewed, the annular arc surface 21 presents symmetrical characteristics. The annular arc surface 21 is generated by an arc, which means that each of its cross-sections is an arc, not a flat one. Due to the rotation of this arc, it forms an overall smooth and continuous curved surface. The annular arc surface 21 is usually convex in the structure in which it is located, that is, it gradually bends outward from the base surface and forms a protrusion, which makes it more three-dimensional and spatially ductile than a plane surface. The conductive terminal 3 and the conductive extension piece 4 can be made of conductive metal components of a specific shape.

[0044] In a specific example, the conductive extension piece 4 has a conductive curved surface 41 on a side facing away from the conductive terminal 3 . The conductive curved surface 41 is parallel to and intersects with the annular arc surface 21 .

[0045] Specifically, the conductive extension sheet 4 is a sheet-like structure electrically connected to the conductive terminal 3. Its primary function is to provide a larger conductive contact area through extension, thereby enhancing the efficiency and stability of electrical conduction. It transmits electrical energy from the charging port to the interior of the earphones and connects through the corresponding position of the conductive terminal 3. This description refers to the other side of the conductive extension sheet 4, that is, the side away from the direct contact with the conductive terminal 3. The conductive terminal 3 is responsible for conducting current, while this side of the conductive extension sheet 4 is responsible for interfacing with other structures in the charging dock (such as the annular arc surface 21). The conductive curved surface 41 refers to the curved surface formed on the side of the conductive extension sheet 4 away from the conductive terminal 3. Unlike a flat surface, it is a curved surface, likely intended to form a good mechanical fit and electrical contact with other components within the charging dock, such as the annular arc surface 21. This curved surface design can expand the contact area, ensure more stable contact between the conductive sheet and the corresponding components, and thus improve conductivity. The parallelism of the conductive curved surface 41 and the annular arc surface 21 means that the conductive curved surface 41 and the annular arc surface 21 have geometrically consistent directionality. In other words, the two curved surfaces extend along the same curvature, indicating that their curvature and shape are similar, and they remain parallel to each other. This parallel design facilitates a larger contact area and ensures even pressure distribution on the conductive extension sheet 4 during charging, preventing contact problems caused by angular deviation. The intersection of the conductive curved surface 41 and the annular arc surface 21 means that the conductive curved surface 41 and the annular arc surface 21 do not exist completely independently, but rather intersect or contact each other in certain areas. "Intersection" here generally refers to the two being properly designed to fit together, allowing for better electrical and mechanical contact between the conductive sheet and the annular arc surface 21. This interactive structure further optimizes the conductive path and ensures stable current conduction during charging. The parallel and intersecting design of the conductive curved surface 41 and the annular arc surface 21 ensures a tight fit between the conductive sheet and the curved contact surface, preventing contact problems caused by flat surfaces. This helps maintain a stable electrical connection when the earphones are plugged into the charging cradle, improving charging efficiency. The primary purpose of the curved surface design is to expand the contact area between the conductive sheet and the annular arc surface 21. The parallel curved surface structure ensures consistent contact pressure across the contact surface. Intersecting curved surfaces can help reduce wear on the conductive sheet during contact, as the curved design evenly distributes contact points, reducing single-point force. Furthermore, the curved surface reduces the accumulation of foreign matter, preventing impurities from affecting contact quality.

[0046] In a specific example, a connecting cavity 11 is defined in the cylindrical clamping portion 1 , and the connecting cavity 11 is connected to the interior of the earphone. A sound outlet hole 22 is defined on the sealing cover 2 , and the sound outlet hole 22 is connected to the connecting cavity 11 .

[0047] Specifically, the cylindrical snap-in portion 1 is the primary structural component for inserting the earphone tail plug into the charging dock. It's responsible for instantly snapping the earphones into the dock and ensuring stable placement. It also protects the internal structure. "Communication cavity 11" refers to the hollow space within the cylindrical snap-in portion 1, which connects the snap-in portion with the earphone's internal structure. This means that communication cavity 11 is more than just a physical space; it also serves to transmit sound or signals. Sound within the earphones propagates through this cavity, ensuring proper sound production. The cavity design allows the earphones' internal acoustic structure to interact with the tail plug to achieve sound transmission. This design optimizes the earphones' acoustic performance, ensuring excellent sound quality during use. Communication cavity 11 allows sound to be transmitted from the earphones' internal unit to the outside, ensuring proper audio signal input without compromising the earphones' airtightness or structural stability. Furthermore, this design does not affect the earphones' charging function, as it is separate from the charging channel and does not interfere with each other. The sound outlet 22 is an opening specifically for sound transmission, located on the sealing cover 2. Its function is to allow sound to be output from the inside of the earphone to the outside, so that the earphone can sound normally. The sound outlet 22 is usually connected with the sound-emitting unit of the earphone, and the sound is directed to the outside through the connecting cavity 11. The sound outlet 22 can ensure that the sound is transmitted from the inside of the earphone to the outside, and at the same time, the design of the sealing cover 2 allows the other parts of the tail of the earphone to remain sealed. This ensures the sound quality of the earphone and prevents moisture and water from entering the interior of the earphone, which helps to extend the service life of the earphone. The connecting design of the connecting cavity 11 and the sound outlet 22 establishes a continuous sound wave, so that the earphone can play audio content normally. The sound outlet 22 and the affecting cavity ensure that the sound path of the earphone is unobstructed, and the sound will not be blocked due to the design of the tail plug. This design also optimizes the acoustic structure of the earphone, thereby improving the sound quality. At the same time, the position and structure of the sound outlet 22 can effectively reduce the sound damage of the earphone when in use, making the audio output clearer and more natural.

[0048] In a specific example, the Bluetooth headset tail plug charging station 100 further includes a protective conductive portion 5, which is covered on the sound outlet 22 and electrically connected to one of the conductive terminals 3;

[0049] A through hole 51 is defined in the protective conductive portion 5 . One side of the through hole 51 is connected to the outside, and the other side of the through hole 51 is connected to the sound outlet 22 .

[0050] Specifically, the protective conductive portion 5 is part of the charging cradle. Its primary function is to protect the sound outlet 22 and also serves as an electrical connection. It provides a degree of physical protection for the sound outlet 22, preventing damage from external impacts. The protective conductive portion 5 is electrically connected to a conductive terminal 3, meaning it not only provides protection but also serves as the electrical connection for the earphones. This design ensures that current can flow smoothly through the protective conductive portion 5 and connect to the rest of the earphones. The protective conductive portion 5 directly covers the sound outlet 22, forming a physical barrier. This design effectively prevents direct impact from external objects, such as large solid particles or water droplets, while maintaining sound transmission. Thanks to the protective conductive portion, the sound outlet 22 remains in good working condition, ensuring that the listener's acoustics are well-balanced. This protective structure enhances durability, especially when used in dusty or drafty environments. The through-hole 51 in the protective conductive portion is a key design element. It provides a controlled channel for sound transmission while maintaining the protective function of the protective conductive portion 5. The through-hole 51 provides a direct channel to the external environment, allowing sound to be transmitted from the inside of the earphone through the sound outlet 22. This design ensures that the earphone is not obstructed when sound is emitted, allowing sound to be output smoothly. The other side of the through-hole 51 is connected to the sound outlet 22, ensuring that sound can be transmitted from the inside of the earphone through the through-hole 51 to the sound outlet. This design optimizes the sound transmission path, making the sound quality of the earphone clearer when sound is emitted. The design of the protective conductive part provides protection for the sound outlet 22 while allowing sound to be transmitted smoothly from the inside of the earphone. This dual function ensures the normal operation of the earphone while preventing the influence of the external environment. When the earphone is in use, sound waves are transmitted from the sound-emitting unit inside the earphone to the cavity, and then emitted through the sound outlet 22. When sound passes through the sound outlet 22, the through-hole 51 of the protective conductive part ensures that the sound can be transmitted to the outside unimpeded, while the protective conductive part 5 itself provides physical protection for the sound outlet 22, preventing interference from objects.

[0051] In a specific example, the Bluetooth headset tail plug charging station 100 further includes a protective conductive portion 5, which is covered on the sound outlet 22 and electrically connected to one of the conductive terminals 3;

[0052] A through hole 51 is defined in the protective conductive portion 5 . One side of the through hole 51 is connected to the outside, and the other side of the through hole 51 is connected to the sound outlet 22 .

[0053] Specifically, positioning the protective conductive portion 5 and the two conductive terminals 3 at three triangular points on the annular arc surface 21 maximizes space utilization, making the entire Bluetooth headset tail plug charging station 100 more compact and streamlined. This layout avoids overcrowding between conductive components and reduces the risk of poor contact or damage due to insufficient space. The three points form a stable triangular structure, enhancing the stability of the entire tail plug charging station. Even when the earphones are placed in the charging station or carried, the stability of the triangle resists deformation or damage, protecting the internal conductive components from impact. Because the conductive terminals 3 and the protective conductive portion 5 are both located at triangular points on the annular arc surface 21, their contact points with the charging station are more uniform. This helps ensure a stable current during charging, improves charging efficiency, and reduces charging issues caused by poor contact. By optimizing the spatial layout and enhancing stability, the charging efficiency and service life of the earphones can be improved, thereby providing a better user experience. A rational layout and stable structure help reduce the failure rate caused by poor contact or damage, reducing maintenance costs for users.

[0054] In a specific example, the protective conductive portion 5 and the conductive terminal 3 connected thereto are formed integrally.

[0055] Specifically, the one-piece molding design makes the connection between the protective conductive part 5 and the conductive terminal 3 more secure, and is not easily separated or damaged by external forces, thereby improving the strength and durability of the entire structure. Since the protective conductive part 5 and the conductive terminal 3 are integrally molded, the electrical connection between them is tighter and more stable, reducing the risk of reduced charging efficiency or charging failure due to poor contact. The one-piece molding design simplifies the manufacturing process, reduces the number of parts and assembly steps, and thus reduces manufacturing costs. Since the connection points between the components are reduced, the one-piece molding design also simplifies subsequent maintenance and repair work. One-piece molding is usually achieved through injection molding, die casting or other similar molding processes. During the manufacturing process, a conductive material (such as copper, silver, etc.) is mixed with plastic or other non-conductive materials or embedded in a mold, and then pressure or heat is applied to mold and solidify the material, thereby obtaining an integrated structure of the protective conductive part 5 and the conductive terminal 3 with conductive properties.

[0056] In a specific example, the conductive terminal 3 and the corresponding conductive extension piece 4 are integrally formed.

[0057] Specifically, in the technical solution of the Bluetooth headset tail plug charging station 100, the "conductive terminal 3" is the key component responsible for establishing an electrical connection with the charging station or other external device, typically having metal contacts 31 to transmit current upon contact. The "conductive extension piece 4" is a thin sheet-like structure connected to the conductive terminal 3, used to expand or enhance the range of the electrical connection. When the conductive terminal 3 and its corresponding conductive extension piece 4 are said to be integrally formed, it means that the two components are molded as an inseparable whole during the manufacturing process. This design ensures a continuous and seamless connection between the conductive terminal 3 and the conductive extension piece 4, thereby providing a stable electrical connection. The integral design ensures that the connection between the conductive terminal 3 and the conductive extension piece 4 is secure and not susceptible to external interference. This stability is crucial for ensuring continuous current transmission, especially during high-power or long-term charging. Since there are no additional connection points or connectors between the conductive terminal 3 and the conductive extension piece 4, the resistance during the electrical connection can be significantly reduced. This helps improve charging efficiency, reduce energy loss, and extend the battery life. The integral design simplifies the manufacturing process, reducing the number of parts and assembly steps. This not only reduces manufacturing costs but also improves production efficiency. Because the connection between the conductive terminals 3 and the conductive extensions 4 is continuous, they are less susceptible to mechanical stress or vibration. This design improves the durability of the entire structure, enabling it to maintain stable performance in harsh environmental conditions.

[0058] In a specific example, the protective conductive portion 5 and the conductive terminal 3 electrically connected thereto are integrally formed.

[0059] Specifically, in the technical context of the Bluetooth headset tail plug charging stand 100, the "protective conductive part 5" refers to a conductive structure covering a specific area (such as the sound outlet 22) that is intended to provide physical protection and electrical connection functions. It is usually made of a conductive material (such as a metal or metal alloy) to ensure good electrical conductivity. The "conductive terminal 3" is a key component for establishing an electrical connection with the charging device or other external device, and is usually designed to be able to make close contact with the corresponding contacts of the charging stand to transmit current. When it is said that the protective conductive part 5 and the conductive terminal 3 electrically connected to it are integrally formed, it means that the two components are molded as a whole during the manufacturing process. The electrical connection between them is direct, seamless, and established during the molding process. The integral molding design ensures that the electrical connection between the protective conductive part 5 and the conductive terminal 3 is continuous and not easily affected by external interference. This stability is crucial to ensuring reliable current transmission, especially in applications requiring high current or long charging times. Because the protective conductive part 5 and the conductive terminal 3 are integrally formed, the connection between them is very strong and can withstand large mechanical stresses. This helps prevent the connection from breaking or loosening due to external forces during use. The unibody design simplifies the manufacturing process, reducing the number of parts and assembly steps. This not only lowers manufacturing costs but also improves production efficiency and reduces quality issues caused by assembly errors. By reducing connection points and potential failure points, the unibody design improves the reliability of the entire charging port. This helps ensure the device functions properly even in harsh environmental conditions, extending its lifespan.

[0060] In one embodiment, the conductive terminal 3 has a metal contact 31 on a side facing away from the sealing cover 2 .

[0061] Specifically, the "conductive terminal 3" is a key component that is typically used to establish an electrical connection between an electronic device (such as a Bluetooth headset, wireless headphones, etc.) and an external charging device. The conductive terminal 3 is usually made of a conductive material (such as copper, silver, gold, or other metals or alloys thereof) to ensure good electrical conductivity.

[0062] The "sealing cover 2" is a protective structure covering the conductive terminal 3 or other sensitive components, designed to prevent moisture, dust or other contaminants from entering the device, thereby protecting the device's electrical performance and structural integrity. The conductive terminal 3 has a metal contact 31 on the side facing away from the sealing cover 2, which means that the conductive terminal 3 is designed with a metal contact 31 on the side opposite the sealing cover 2. These metal contacts 31 are key parts for establishing an electrical connection with an external charging device or other external device, and are usually designed to be able to closely contact the corresponding contacts of the charging base to transmit current. The metal contacts 31 are made of conductive material and have excellent conductivity, which can ensure smooth transmission of current. This is crucial to ensuring charging efficiency and device performance. The metal contacts 31 are usually designed to have a certain degree of elasticity and wear resistance to ensure that they can maintain good contact performance after long-term use and multiple plugging and unplugging. This helps to reduce charging failures or device damage caused by poor contact. The metal contacts 31 are usually specially treated to improve their corrosion resistance and oxidation resistance. This helps prevent contact corrosion or oxidation caused by environmental factors (such as humidity, temperature, chemicals, etc.), thereby extending the life of the device. The size and shape of the metal contacts 31 are generally designed to match the corresponding contacts of the charging station to ensure good fit and contact area. This helps reduce energy loss and reduced charging efficiency caused by poor contact.

[0063] In one embodiment, the conductive terminals 3 and the conductive extension pieces 4 are made of copper.

[0064] Specifically, the conductive terminals 3 and conductive extension piece 4 are two key electrical connection components. The conductive terminals 3 are typically used to establish an electrical connection with an external device (such as a charging station), while the conductive extension piece 4 is used to extend or enhance the range and stability of the electrical connection. Copper, as a widely used conductive material, is widely chosen for its excellent conductivity, mechanical properties, and corrosion resistance. Copper's conductivity is second only to silver, but compared to silver, copper is less expensive and has better processability, making it more common in practical applications. Copper's excellent conductivity and low resistivity ensure smooth current transmission, which is crucial for ensuring charging efficiency and device performance. Copper has excellent ductility and toughness, and can withstand certain mechanical stresses and deformation without breaking. This helps ensure that the conductive terminals 3 and conductive extension piece 4 maintain good connection performance even after prolonged use and repeated plugging and unplugging. Copper also has excellent corrosion resistance to many chemicals and environments, and can maintain stable performance in harsh environments such as moisture and corrosive environments. This helps extend the life of the device. Copper is easily processed into various shapes and sizes to meet the needs of different application scenarios. At the same time, copper has good welding and electroplating properties, which makes it easy to connect with other components and perform surface treatment.

[0065] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
