[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] Please see Figures 1 to 9 This utility model provides a technical solution:

[0036] A Bluetooth headset with detachable ear hooks and main unit, including a male connector 3 and a female connector 4;

[0037] The male connector 3 is adapted to the female connector 4.

[0038] The male connector 3 is provided with a movable groove 22 inside;

[0039] The movable groove 22 is provided with a sliding wedge-shaped locking tongue 7;

[0040] The inner wall of the connecting female seat 4 is provided with a locking groove 17;

[0041] By locking and disengaging the wedge-shaped locking tongue 7 with the locking groove 17, the male connector 3 and the female connector 4 are in a separable mechanical connection state.

[0042] The male connector 3 is fixedly installed at the bottom of the ear hook 1; a mounting bracket 9 is provided on the outer side of the earphone body 2, and a mounting seat 5 is provided on the top of the mounting bracket. The top of the mounting seat 5 is fixedly installed to the bottom of the female connector 4. The ear hook 1 is made of flexible TPU material, and only the connecting cable is installed inside; the earphone body 2 is made of ABS engineering plastic, and its internal components include a battery unit, a sound coil, a noise reduction module, and a control circuit. These structures are conventional designs in the field and have been disclosed in the prior art, and will not be described in detail here. When any part of the ear hook 1 or the earphone body 2 is damaged, only the corresponding part needs to be replaced, without replacing the entire product. This reduces the user's maintenance costs and improves the product's lifespan and economy. This modular design makes maintenance more convenient and also allows users to replace ear hooks or earphone bodies of different specifications according to their needs.

[0043] The male connector 3 is externally provided with a male connector shell 6, and internally provided with a male connector end circuit board 15. The male connector end circuit board 15 is provided with an electromagnetic contact pin 13, and a magnetically conductive metal sheet 14 is provided at the bottom of the male connector end circuit board 15. The electromagnetic contact pin 13 adopts a structure composed of a needle tube, a spring, and a needle tip, and has elastic telescopic characteristics. It is used to establish an electrical connection path between the ear hook 1 and the earphone body 2, realizing the transmission of audio signals and power. This structure is existing technology and will not be described in detail here. The magnetically conductive metal sheet 14 is made of electrical pure iron DT4C material. This material has high magnetic permeability, high saturation magnetic induction intensity, and low remanence, which can effectively guide magnetic lines of force and enhance the magnetic attraction effect. At the same time, its low remanence characteristic can avoid magnetic interference to the speaker unit and other sensitive circuits inside the earphone, ensuring that the normal operation of the earphone is not affected. The magnetically conductive metal sheet 14 cooperates with the magnet at the corresponding position inside the female connector 4, providing auxiliary positioning and attraction force for the main mechanical connection, making the docking process between the male connector and the female connector smoother and more accurate.

[0044] A cover plate 23 is fixedly installed on the male connector housing 6, and a sealing ring 21 is fixedly installed on the cover plate 23. The sealing ring 21 is made of silicone material and is fixed in the sealing groove of the cover plate 23 by interference fit. When the male connector 3 and the female connector 4 are mated, the sealing ring 21 is compressed and deformed, forming a tight seal between the mating surfaces of the male connector housing 6 and the female connector housing 16. This sealing structure uses existing mature waterproof technology, which can effectively prevent sweat, moisture and dust from entering the connector, providing reliable protection for the internal electromagnetic pins 13 and circuit board 15, thereby ensuring the stability of the electrical connection and extending its service life. This design ensures waterproof performance without affecting the normal insertion and removal operation of the connector.

[0045] The movable groove 22 is equipped with a button rod 12, one end of which is connected to the release button 11, and the other end is connected to the wedge-shaped locking tongue 7. A locking tongue return spring 10 is sleeved on the button rod 12. The movable groove 22 is a key structure located inside the male connector 3, providing a precise moving track and accommodating space for the wedge-shaped locking tongue 7, ensuring that the wedge-shaped locking tongue 7 can only slide smoothly in a predetermined direction, thereby achieving reliable locking and unlocking. One end of the button rod 12 is fixedly connected to the release button 11, and the other end contacts or connects to the tail end of the wedge-shaped locking tongue 7. When the user presses the release button 11, the button rod 12 transmits the pressing force to the wedge-shaped locking tongue 7, driving it to slide backward along the movable groove 22, causing its front locking plane 8 to disengage from the locking groove 17, thereby achieving rapid disengagement. The combination of the button rod 12 and the release button 11 adopts a mature lever transmission principle, with a simple structure and high transmission efficiency, providing users with a convenient one-button quick unlocking experience. This design makes the separation process between the ear hook 1 and the headphone body 2 quick and reliable, further demonstrating the practical value of this detachable structure.

[0046] The wedge-shaped locking tongue 7 has a locking plane 8 on its outer surface. The locking plane 8 is a key load-bearing surface located at the front end of the wedge-shaped locking tongue 7. The outer contour of the wedge-shaped locking tongue 7 is slightly larger than the outer wall of the male connector housing 6, forming a suitable interference fit with the inner wall of the connecting female connector 4. This precision design ensures smooth connection and reliable locking. During connection, when the male connector is inserted into the female connector, the locking plane 8 first contacts the inner wall of the female connector. Due to the interference fit, the inner wall of the female connector exerts a compressive force on the locking plane 8. This force is transmitted through the wedge-shaped locking tongue 7 to the locking tongue return spring 10, causing it to be compressed and stored. During this stage, the spring acts as a compression buffer, making the insertion smooth and stable. When the male connector continues to be inserted until the locking plane 8 is fully aligned with the locking groove 17, the compressive force from the inner wall of the connecting female connector 4 disappears. The compressed latch return spring 10 immediately releases its energy, generating a rapid spring-in force that pushes the wedge-shaped latch 7 forward, allowing the locking plane 8 to quickly and accurately enter the locking groove 17, completing the mechanical locking. This function of the spring ensures the timeliness and accuracy of locking. During unlocking, pressing the release button 11 forces the wedge-shaped latch 7 backward via the button push rod 12, disengaging it from the locking groove 17. At this time, the latch return spring 10 is compressed again. When the lock is completely released, if the release button 11 is released, the restoring force of the latch return spring 10 will push the wedge-shaped latch 7 to automatically return to its initial ready position, preparing for the next connection. This automatic reset function of the spring ensures the continuous usability and ease of operation of the product. The latch return spring 10 achieves a triple function: providing compression buffer during insertion, providing rapid spring-in force during locking, and providing automatic reset capability after unlocking. This ingenious design fully utilizes the characteristics of the spring, making the entire connection-locking-unlocking-reset process a complete working cycle.

[0047] The female connector 4 is externally provided with a female connector shell 16. A locking groove 17 is formed on the lower part of the inner wall of the female connector shell 16. An electromagnetic contact 19 and a small magnetic ring 20 are located at the bottom of the interior of the female connector shell 16. A reset plate 18 is located at the end of the locking groove 17. The small magnetic ring 20 is made of neodymium iron boron permanent magnet material, and after magnetization and stabilization treatment, it has high magnetic energy product and stable magnetic properties. The magnetic circuit is precisely designed to form an effective magnetic force cooperation with the magnetically conductive metal sheet 14 in the male connector 3, providing auxiliary positioning and holding force for the main mechanical connection. At the same time, its magnetic field strength is strictly controlled to avoid interfering with the speaker unit and audio signal transmission inside the earphone, ensuring normal operation of the earphone. The electromagnetic contact 19 is made of gold-plated phosphor bronze sheet, which has good conductivity and elasticity, and cooperates with the electromagnetic pin 13 in the male connector 3. When the male connector and female connector are fully connected, the electromagnetic pin 13 maintains reliable contact with the electromagnetic contact 19 under the action of a spring, establishing a stable electrical connection path and realizing the functions of audio signal transmission and power supply. The locking groove 17 is located on the lower part of the inner wall of the female seat housing 16. This design allows the pull-out force borne by the wedge-shaped locking tongue 7 in the locked state to be directly transmitted to the lower structure of the female seat housing 16, forming a stable mechanical support and improving the stability and reliability of the connection. The reset plate 18 is a triangular guide plate protruding into the female seat housing 16, made of POM engineering plastic with excellent wear resistance. The inclined surface of the reset plate 18 cooperates with the locking plane 8 of the wedge-shaped locking tongue 7, guiding the wedge-shaped locking tongue 7 to smoothly exit from the locking groove 17 during the unlocking process, ensuring the smooth completion of the unlocking action.

[0048] The triangular bevel of the reset plate 18 and the locking plane 8 of the wedge-shaped latch 7 form a precise fit. During unlocking, when the male connector 3 is subjected to an outward pulling force, the wedge-shaped latch 7 moves outward along with the male connector. At this time, the locking plane 8 comes into contact with the inclined surface of the reset plate 18. Since the reset plate 18 is fixedly installed, its triangular bevel will exert two component forces on the moving wedge-shaped latch 7: a normal force perpendicular to the bevel and a guiding force parallel to the bevel. This forces the latch to continue moving outward while simultaneously displacing inward along the bevel of the reset plate 18 towards the male connector 3. As it moves outward with the male connector and simultaneously retracts inward guided by the bevel, the locking plane 8 can smoothly disengage from the locking groove 17 without jamming or interference. By locking the locking plane 8 of the wedge-shaped latch 7 at the top of the locking groove 17, reliable positioning of the male connector 3 is achieved. This top-locking design allows the pull-out force to be directly borne by the upper wall of the locking groove 17, forming an efficient force transmission path. This not only improves the stability of the connection but also avoids wear and loosening problems that may occur during long-term use, ensuring the reliability of the connection throughout the product's lifespan.

[0049] During installation, the user aligns the male connector 3 with the female connector 4. The small magnetic ring 20 and the magnetically conductive metal plate 14 generate magnetic attraction, automatically guiding the male connector 3 to accurately insert into the insertion cavity of the female connector 4. During insertion, the locking plane 8 of the wedge-shaped locking tongue 7 is pressed against the inner wall of the female connector, pushing the wedge-shaped locking tongue 7 to compress the locking tongue return spring 10 and slide it into the moving groove 22. When the male connector 3 is in place and the locking plane 8 is aligned with the locking groove 17, the pressing force disappears, the locking tongue return spring 10 is released instantly, pushing the wedge-shaped locking tongue 7 forward into the locking groove 17, completing the mechanical locking. Simultaneously with mechanical locking, the electromagnetic contact pin 13 and the electromagnetic contact 19 make close contact, establishing a stable electrical connection.

[0050] During disassembly, the user presses the release button 11. The release button 11 pushes the push rod 12, which pulls the wedge-shaped locking tongue 7 backward, causing the locking plane 8 to disengage from the locking groove 17, thus releasing the mechanical lock. When the male connector is pulled outward, the locking plane 8 of the wedge-shaped locking tongue 7 contacts the inclined surface of the reset plate 18. The inclined surface force compels the wedge-shaped locking tongue 7 to continue retracting, ensuring its smooth and complete exit from the locking area and preventing jamming. The male connector 3 and the female connector 4 are separated, and simultaneously, the electromagnetic pin 13 and the electromagnetic contact 19 are disconnected, cutting off the circuit connection. After releasing the release button 11, the locking tongue reset spring 10 pushes the wedge-shaped locking tongue 7 to automatically return to its initial position, preparing for the next installation.

[0051] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
