Description

Technical Field

[0001] This utility model relates to the structure of a pin, and more particularly to the assembly structure of a pin for a Bluetooth headset. Background Technology

[0002] Currently, open-back Bluetooth earphones on the market typically use an internal pin assembly method. One end of the pin passes through the housing from the inside out and is then secured, with the pin integrally molded to the shell. This assembly method has several drawbacks:

[0003] 1. Unstable installation: Installing from the inside of the housing to the outside may cause the pins to be loosely fixed to the internal structure of the earphone and easily come loose.

[0004] 2. Spatial interference: The internal space of Bluetooth headsets is limited. When assembling from the inside out, the orientation of the pins is easily incorrect. Incorrect installation orientation can cause the pins to interfere with other components, affecting the overall structure of the headset.

[0005] 3. Assembly difficulties: In this assembly method, the pins are usually placed in a fixed position first, then the PFC (flexible circuit board) is placed on top, and then the connection is soldered to connect the two together. During soldering, it is impossible to press the pins down, resulting in poor product quality and easy soldering misalignment. Utility Model Content

[0006] The purpose of this utility model is to provide an assembly structure for the pins of a Bluetooth headset, so as to solve the problems existing in the existing pin assembly structure.

[0007] According to one aspect of the present invention, a pin assembly structure for a Bluetooth headset is provided, including a housing, the housing having a cavity, an FPC and a pin on the housing, one end of the pin being inserted into the housing in an external manner and electrically connected to the FPC.

[0008] In some implementations, an FPC reinforcing plate is also included, which is disposed at the lower end of the FPC.

[0009] In some embodiments, there are two pins, and two first through holes are provided at corresponding positions on the housing, with one end of the pin inserted into the first through hole from the outside.

[0010] In some embodiments, a first sealant is applied to the connection between the pin and the through hole.

[0011] In some embodiments, a receiving portion is formed on the inner wall of the housing, and the FPC reinforcing plate and the lower end of the FPC are both inserted into the receiving portion.

[0012] In some embodiments, the housing has an annular protrusion that forms a receiving portion.

[0013] In some embodiments, the FPC reinforcing plate and the lower end of the FPC are provided with three second through holes, and the housing is provided with a positioning post. The positioning post passes through the second through hole in the middle of the FPC reinforcing plate and the lower end of the FPC, and one end of the two pins is respectively provided on the other two second through holes.

[0014] The beneficial effects of this utility model are as follows: In order to solve the technical problems existing in the prior art, this utility model adopts a method of assembling the earphone from the outside to the inside with pins. After the pins are assembled from the outside to the inside, they are welded to the FPC for fixation. This assembly method can solve the problems existing in the prior art and also has the following advantages.

[0015] 1. Better sealing: The pins are inserted from the outside, and after insertion, the interface is better sealed with sealant or other waterproof materials, which can effectively prevent moisture and dust from entering the earphone and improve the waterproof and dustproof rating of the earphone.

[0016] 2. Reduce internal contamination: External insertion reduces the risk of internal components being contaminated during assembly, eliminating the need to insert hands or tools deep inside the headphones.

[0017] 3. Easier to operate: Inserting the pins from the outside usually allows for more intuitive operation, making it easier for assemblers to align the interfaces and reducing assembly difficulty and time.

[0018] 4. Easier maintenance: If pins or other related parts need to be replaced, external operation allows for faster maintenance without disassembling the entire internal structure of the earphone.

[0019] 5. Reduce internal stress: Inserting from the outside can avoid applying excessive pressure or stress to internal components during assembly, thus improving the stability of the internal structure.

[0020] 6. More stable charging and connection: The externally inserted pins can better align with the interface of the charging case or other devices, reducing poor contact and improving the stability of charging and signal transmission.

[0021] 7. Cleaner appearance: External insertion reduces the exposure of internal interfaces, making the inside of the headphones look cleaner and reducing the accumulation of dust and debris.

[0022] 8. Simplified quality control: During assembly, external insertion makes quality inspection easier, ensuring that the pins are inserted in the correct direction and position. Attached Figure Description

[0027] 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.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Figures 1-3 The diagram schematically illustrates the pin assembly structure of a Bluetooth headset according to one embodiment of the present invention.

[0030] like Figures 1-3 As shown, a pin assembly structure for a Bluetooth headset includes a housing 1. Figure 1Only the lower half of the housing 1 is shown. To make the internal structure of the housing 1 more intuitive, the upper half of the housing 1 is hidden. The housing 1 itself is a basically closed structure. The housing 1 has an integrally formed cavity 11. An FPC (flexible printed circuit board) 2 and a pin 3 are installed on the housing 1. One end of the pin 3 is inserted into the housing 1 externally and electrically connected to the FPC 2. Of course, after one end of the pin 3 is inserted into the housing 1 externally, it will also be soldered to the FPC 2 to form an electrical connection. Therefore, the focus of this utility model is that the pin is inserted from the outside.

[0031] To secure the lower end of the FPC (Flexible Printed Circuit) 2 to the housing 1 without deformation at the connection point between the FPC 2 and the pins, this invention includes an FPC reinforcing plate 4. The reinforcing plate 4 is installed at the lower end of the FPC. Since the FPC is a flexible circuit board, it possesses a certain degree of plasticity and deformability. Therefore, the reinforcing plate 4 serves to fix and strengthen the lower end of the FPC, helping to solder the pins 3 to the FPC. In this embodiment, the shape of the reinforcing plate 4 matches the shape of the lower end of the FPC, ensuring a tight fit between the reinforcing plate 4 and the lower end of the FPC.

[0032] In this embodiment, there are two pins 3. Two first through holes 12 are integrally formed at corresponding positions on the housing 1. One end (inner end) of the pin 3 is inserted into the first through hole 12 from the outside and welded to the FPC and the FPC reinforcing plate 4. The other end (outer end) of the pin 3 is as follows... Figure 2 As shown, located outside the housing 1, the outer ends of the two pins 3 can be electrically connected to a power source to charge the earphones. Of course, the diameter of the first through hole 12 on the housing 1 in this invention is larger than the diameter of one end (inner end) of the pin 3. Therefore, the inner end of the pin 3 can pass through the first through hole 12 and be inserted into the FPC, and finally soldered together. Furthermore, the diameter of the first through hole 12 is smaller than the diameter of the other end (outer end) of the pin 3, preventing the other end (outer end) of the pin 3 from entering the interior of the housing 1 through the first through hole 12.

[0033] In the prior art, the pin is installed from the inside out. One end (outer end) of the pin is passed through from the inside to the outside and fixed in place. The pin is integrally formed with the housing. Therefore, the housing in the prior art will also have a through hole corresponding to the pin. The diameter of the through hole will be slightly larger than the diameter of the outer end of the pin to ensure that the outer end of the pin can pass through the through hole.

[0034] In this embodiment, sealant is applied to the connection point between the pin 3 and the first through hole 12. By applying the sealant, the pin 3 can be fixed in place.

[0035] like Figure 1 and Figure 3 As shown, in this embodiment, a receiving portion 131 is formed on the inner wall of the housing 1. The FPC reinforcing plate 4 and the lower end of the FPC are both stuck in the receiving portion 131. Therefore, the receiving portion 131 can fix the FPC reinforcing plate 4 and the lower end of the FPC.

[0036] In this embodiment, an annular protrusion 13 is integrally formed in the housing 1, and the annular protrusion 13 forms a receiving portion 131. The annular protrusion 13 is a stepped component, and the receiving portion 131 is formed in the middle, which can serve to fix the FPC reinforcing plate 4 and the lower end of the FPC. The shape of the receiving portion 131 formed by the annular protrusion 13 is the same as the shape of the FPC reinforcing plate 4 and the lower end of the FPC.

[0037] In this embodiment, the FPC reinforcing plate 4 and the lower end of the FPC are integrally formed with three second through holes 5. A positioning post 14 is installed on the housing 1. The upper end of the positioning post 14 passes through the second through hole 5 in the middle of the FPC reinforcing plate 4 and the lower end of the FPC. One end of each of the two pins 3 is installed on the other two second through holes 5. For example, one end of the left pin 3 passes through the FPC reinforcing plate 4 and the second through hole 5 on the left side of the FPC, and one end of the right pin 3 passes through the FPC reinforcing plate 4 and the second through hole 5 on the right side of the FPC.

[0038] This invention offers the following advantages: 1. Improved sealing: The pin 3 is inserted externally, and after insertion, the interface is better sealed with sealant or other waterproof materials. This effectively prevents moisture and dust from entering the earphone, improving its waterproof and dustproof rating. 2. Reduced internal contamination: External insertion reduces the risk of internal component contamination during assembly, eliminating the need to insert hands or tools deep into the earphone. 3. Easier operation: External insertion of the pin 3 allows for more intuitive operation, making it easier for assemblers to align the interface and reducing assembly difficulty and time. 4. Easier maintenance: Replacing the pin 3 or other related components from the outside allows for faster maintenance without disassembling the entire internal structure of the earphone. 5. Reduced internal stress: External insertion avoids applying excessive pressure or stress to internal components during assembly, thus improving the stability of the internal structure. 6. More stable charging and connection: Externally inserted pin 3 better aligns with the interface of the charging case or other devices, reducing poor contact and improving the stability of charging and signal transmission. 7. Cleaner Appearance: External insertion reduces the exposure of internal interfaces, making the inside of the earphone look neater and reducing the accumulation of dust and debris. 8. Simplified Quality Control: During assembly, external insertion facilitates quality checks, ensuring the correct insertion direction and position of pin 3.

[0039] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
