[0024] Wireless earphones usually use FPC to connect the functional components inside the wireless earphones to the motherboard, and the motherboard and FPC are usually electrically connected using a BTB connector. During the use of wireless earphones, the wireless earphones may fall or be impacted, which may cause the BTB connector to disconnect, and then cause the wireless earphones to not work properly.
[0025] The utility model provides a BTB connector anti-drop structure, which is mainly used in wireless headphones. For details, please refer to Figures 1 to 3 The BTB connector anti-dropout structure includes PCB1, FPC2, a first connector 3, a second connector 4 and an anti-dropout member 5; the first connector 3 is arranged on the PCB1, and the second connector 4 is electrically connected to a surface of the FPC2 close to the PCB1; the anti-dropout member 5 is arranged on a surface of the FPC2 away from the PCB1; the second connector 4 is plugged into the first connector 3, and the anti-dropout member 5 is buckled into the first connector 3 to maintain the plugged-in state of the first connector 3 and the second connector 4.
[0026] Among them, the anti-dropping member 5 can be made of steel material; the first connector 3 is the male seat of the BTB connector, the second connector 4 is the female seat of the BTB connector, and the second connector 4 and the first connector 3 are plugged in through pins, thereby realizing the connection between FPC2 and PCB1. In the process of the second connector 4 being plugged into the first connector 3, the anti-dropping member 5 and the first connector 3 are also interlocked with each other. When the second connector 4 is plugged into the first connector 3, the anti-dropping member 5 and the first connector 3 are also interlocked, realizing the anti-dropping function between the first connector 3 and the second connector 4, thereby solving the problem of disconnection of the BTB connector caused by the falling or impact of the wireless headset during the use of the wireless headset. Specifically, the anti-dropping member 5 is bonded to the side of the FPC2 away from the PCB1, the first connector 3 is welded to the PCB1, and the second connector 4 is welded to the FPC2.
[0027] It can be understood that, compared with the method of setting foam to support the top of the side wall or the method of limiting the position with multiple steel sheets in the prior art, the utility model sets an anti-dropping component 5 and utilizes the mutual engagement between the anti-dropping component 5 and the first connecting component 3 to achieve anti-dropping between the first connecting component 3 and the second connecting component 4, thereby solving the problem of disconnection of the BTB connector due to the wireless headset falling or being impacted. On the basis of ensuring the realization of the anti-dropping function, the adaptability of the anti-dropping structure to the internal space of the wireless headset is improved, the number of anti-dropping structural components of the BTB connector is reduced, the production cost is reduced, and the assembly efficiency is improved.
[0028] For further information, please refer to Figure 2 and Figure 3 In one embodiment, the anti-dropping member 5 includes a covering portion 51 and a buckling portion 52 extending along both ends of the covering portion 51 .
[0029] The covering portion 51 is used to abut against the second connector 4 to ensure the reliability of the plug-in connection between the second connector 4 and the first connector 3, and the buckle portion 52 is used to achieve the fixation between the buckle and the first connector 3, thereby ensuring the stability of the plug-in connection between the second connector 4 and the first connector 3, and realizing the anti-drop function of the BTB connector. Specifically, the anti-drop member 5 is a buckle-shaped member, which can be made of steel material, and the buckle portion 52 is formed by bending the two ends of the steel sheet, and the main body of the steel sheet serves as the covering portion 51 of the buckle.
[0030] Furthermore, in one embodiment, a buckling protrusion 31 is disposed on one of the buckling portion 52 and the first connecting member 3 , and a buckling groove 53 is disposed on the other one.
[0031] Please refer to Figure 2 and Figure 3In a preferred embodiment, a buckling groove 53 is provided on the buckling portion 52, and a buckling protrusion 31 is provided on the first connecting member 3. It can be understood that the above-mentioned embodiment is for illustration only, and does not limit the formation of the buckling groove 53 and the buckling protrusion 31.
[0032] Specifically, a buckling groove 53 is respectively provided on the buckling parts 52 at both ends of the anti-dropping member 5 , and buckling protrusions 31 corresponding to and cooperating with the buckling grooves 53 are also formed at both ends of the first connecting member 3 .
[0033] After the second connector 4 is plugged into the first connector 3, the buckling protrusion 31 is embedded in the corresponding buckling groove 53, so that the buckling member can be buckled on the first connector 3, and then the second connector 4 can be pressed against the first connector 3, ensuring the reliability of the connection between the first connector 3 and the second connector 4. It can be understood that by adopting the buckling protrusion 31 and the buckling groove 53, on the basis of ensuring the anti-detachment function of the BTB connector, the number of structural parts that realize the anti-detachment function is effectively reduced, the adaptability to the internal space of the wireless headset is improved, the production cost is reduced, and the assembly efficiency is improved.
[0034] Further, to improve the efficiency of assembly and disassembly of the anti-dropping member 5, please refer to Figure 2 and Figure 3 In one embodiment, a first guide surface 32 is formed on the end of the buckling protrusion 31 . A second guide surface 54 matching with the first guide surface 32 is formed on the end of the buckling portion 52 .
[0035] Among them, the first guide surface 32 and the second guide surface 54 are both arc-shaped surfaces, and both the first guide surface 32 and the second guide surface 54 play the role of guiding and assisting the buckling. It can be understood that by forming the first guide surface 32 on the end of the buckling protrusion 31 and forming the second guide surface 54 matching the first guide surface 32 on the end of the buckling portion 52, the efficiency of assembling between the anti-dropping member 5 and the first connecting member 3 can be improved.
[0036] Specifically, when the anti-slip member 5 is fastened to the first connecting member 3, the second guide surface 54 at the end of the fastening portion 52 contacts the first guide surface 32 at the end of the fastening protrusion 31, so that the fastening portion 52 can slide along the fastening protrusion 31 better, and then the fastening protrusion 31 can be fastened into the fastening groove 53 more quickly, thereby improving the efficiency of assembling the anti-slip member 5. Similarly, due to the mutual cooperation between the first guide surface 32 and the second guide surface 54, the anti-slip member 5 can be removed from the first connecting member 3 more quickly, thereby improving the efficiency of removing the anti-slip member 5.
[0037] Furthermore, in a preferred embodiment, the snap-fitting protrusion 31 and the snap-fitting groove 53 are clearance-fitted. It is understandable that the clearance-fitting between the snap-fitting protrusion 31 and the snap-fitting groove 53 can facilitate the assembly and disassembly of the anti-slip component 5 and the first connecting component 3 to a certain extent.
[0038] In summary, the anti-dropout structure of the BTB connector provided by the utility model realizes the anti-dropout between the first connecting member 3 and the second connecting member 4 by setting an anti-dropout member 5 and utilizing the mutual engagement between the anti-dropout member 5 and the first connecting member 3, thereby solving the problem of disconnection of the BTB connector due to the wireless headset falling or being impacted. On the basis of ensuring the realization of the anti-dropout function, the adaptability of the anti-dropout structure to the internal space of the wireless headset is improved, the number of anti-dropout structural parts of the BTB connector is reduced, the production cost is reduced, and the efficiency of assembly is improved.
[0039] The utility model also provides an earphone, which includes the anti-drop structure of the BTB connector mentioned in the above embodiment, and the earphone can effectively solve the problem of disconnection of the BTB connector caused by the wireless earphone falling or being impacted during use.
