[0028] See also Figure 1-3 The present application proposes a USB adapter, comprising a first shell 1 and a second shell 2, wherein a first adapter female connector 3 and a second adapter female connector 4 are disposed in the first shell 1 and the second shell 2, and the first adapter female connector 3 and the second adapter female connector 4 are commonly connected to a circuit board 5;

[0029] The first shell 1 and the second shell 2 serve as the external structure of the USB adapter, and can protect the internal components such as the adapter female connector and the circuit board 5 from physical damage such as impact, squeezing, dust and moisture. When in use, a USB data cable with a Type-A interface can be inserted into the first adapter female connector 3, and then a USB data cable with a Type-C interface can be inserted into the second adapter female connector 4 to achieve the wiring function. The circuit board 5 is one of the core components of the USB adapter. It is responsible for transmitting and converting the signals received by the first adapter female connector 3 and the second adapter female connector 4. The circuits and components on the circuit board 5 can process data signals and power signals to ensure that they can be correctly transmitted to the target device.

[0030] A connecting plate 6 is provided on a side of the first shell 1 close to the second shell 2, and a plurality of limiting grooves 7 are provided on the connecting plate 6. A plurality of protrusions 8 are provided on a side of the second shell 2 close to the first shell 1, and the protrusions 8 cooperate with the limiting grooves 7.

[0031] The interplay between the retaining grooves 7 on the connecting plate 6 and the protrusions 8 on the second housing 2 ensures a tight fit between the first housing 1 and the second housing 2 after assembly, preventing loosening or displacement. This significantly enhances the overall structural stability of the USB adapter, making it more reliable during use. The tight fit between the retaining grooves 7 and the protrusions 8 also effectively prevents deformation or damage to the housings due to prolonged use or improper operation, thereby increasing the durability and service life of the USB adapter.

[0032] By reasonably designing the limiting groove 7 and the protrusion 8, the appearance of the USB adapter can be made neater and more beautiful, thereby improving the overall texture of the product and the user experience.

[0033] The first shell 1 is also provided with a snap fastener 9, which includes a connecting portion 901 and a bending portion 902. One end of the connecting portion 901 is connected to the first shell 1 and extends toward the second shell 2, and the other end of the connecting portion 901 is connected to the bending portion 902; the second shell 2 is provided with a connecting groove 10, and a snap hole 11 is opened in the connecting groove 10. The part of the connecting portion 901 that extends beyond the first shell 1 is located in the connecting groove 10, and the bending portion 902 is snap-connected to the snap hole 11.

[0034] The fastener 9 provides additional fixing force for the first shell 1 and the second shell 2 through the tight fit between the bent portion 902 and the fastener hole 11 , thereby enhancing the stability of the shells.

[0035] When the connecting portion 901 is correctly inserted into the connecting slot 10 and the bent portion 902 is tightly fitted into the snap hole 11, the joint between the first shell 1 and the second shell 2 becomes very neat and smooth. This joint avoids the awkward feeling caused by exposed fasteners such as screws and nuts, making the overall appearance of the USB adapter more unified and coordinated.

[0036] like Figure 2-4 As shown, in some embodiments, fixing grooves 12 are provided on both sides of the inner walls of the first shell 1 and the second shell 2, and bending plates 13 are provided on both sides of the first adapter female connector 3 and the second adapter female connector 4, and the bending plates 13 are located in the fixing grooves 12.

[0037] The matching design of the fixing groove 12 and the bending plate 13 can serve as a precise positioning mechanism to help manufacturers accurately fix the first adapter female connector 3 and the second adapter female connector 4 in the housing during the assembly process, reduce assembly errors, and ensure the correct connection between the adapter female connector and internal components such as the circuit board 5, thereby improving the overall quality and consistency of the product.

[0038] like Figure 2-3As shown, in some embodiments, the fixing slot 12 includes a plane 1201 and two inclined surfaces 1202 , and the two inclined surfaces 1202 are respectively arranged on both sides of the plane 1201 .

[0039] The design of the inclined surface 1202 makes it easier to align the bent plate 13 of the adapter female connector when inserting it into the fixing slot 12, reducing errors and difficulties in the assembly process, simplifying the assembly steps, and improving assembly efficiency, allowing manufacturers to produce high-quality USB adapters more quickly.

[0040] Due to the presence of the inclined surface 1202, the fixing groove 12 can adapt to different sizes of the bent plate 13. This design increases the versatility and flexibility of the USB adapter, allowing manufacturers to use different specifications of adapter female connectors to meet the needs of different customers.

[0041] In some embodiments, as Figure 4 As shown, fixing plates 14 are provided on both sides of the first female adapter 3 and the second female adapter 4 , and the circuit board 5 is provided in the fixing plates 14 .

[0042] The fixing plate 14 provides additional support for the circuit board 5, thereby enhancing the stability of the entire female adapter structure and ensuring the reliability of signal transmission or power transmission.

[0043] In some embodiments, as Figure 4 As shown, a convex strip 15 is provided on the surface of the first female adapter 3 and the second female adapter 4 connected to the circuit board 5 .

[0044] The design of the ridges 15 increases the contact area with the air, thereby improving heat dissipation efficiency. When the components on the circuit board 5 are operating, heat is generated. The presence of the ridges 15 allows this heat to be dissipated more quickly through air convection and radiation. In practical applications, the provision of the ridges 15 can also enhance air convection. When the circuit board 5 is installed inside a device, there is usually a certain amount of air flow to remove heat. The design of the ridges 15 can make it easier for air to convect on the surface of the circuit board 5, thereby accelerating heat dissipation.

[0045] In some embodiments, as Figure 2 As shown, a groove 16 is provided on the inner side of the fastener 9 , and the groove 16 extends from one end of the fastener 9 to the other end.

[0046] The groove 16 allows the latch 9 to deform elastically when subjected to external forces, helping it to better adapt to and be fixed within the connection slot 10, thereby improving the stability and durability of the connection. Furthermore, the groove 16 can reduce the material used in the latch 9, thereby reducing the weight of the entire USB adapter, making it easier to carry and use.

[0047] In some embodiments, as Figure 2 As shown, the connecting plate 6 is provided with a fixing hole 17 .

[0048] The cooperation between the fixing holes 17 and fixing parts such as screws can ensure that the USB adapter is accurately fixed at a desired position.

[0049] In some embodiments, as Figure 4 As shown, a conductive foam 18 is further included. The conductive foam 18 is located on a side of the first female adapter 3 and the second female adapter 4 away from the circuit board 5 .

[0050] The conductive foam 18 has excellent electromagnetic shielding properties, effectively blocking and reducing the interference of external electromagnetic waves on the internal circuit of the USB adapter. This shielding effect is crucial for protecting the stability and reliability of the circuit, especially in situations with complex electromagnetic environments or strong electromagnetic interference.

[0051] By reducing interference from external electromagnetic waves, the conductive foam 18 helps improve the quality of USB adapter transmission signals, ensures accurate data transmission, reduces bit error rates and transmission errors, and thus improves the overall performance of the device and user experience.

[0052] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
