Description

Technical Field

[0001] This utility model belongs to the field of electronic accessories technology, and specifically relates to an adapter. Background Technology

[0002] With the rapid development and increasing multifunctionality of electronic devices, adapters, as core components for device connectivity and data transmission, face increasingly stringent requirements for reliability, durability, and performance. However, existing adapters still suffer from numerous technical bottlenecks in structural design, protection performance, and manufacturing processes, necessitating innovative solutions. The main problems with existing technologies are: insufficient interface protection; fully enclosed designs, while dustproof and waterproof, lead to poor heat dissipation, such as excessively high interface temperatures during fast charging, and also increase size and weight; exposed designs are susceptible to external damage such as contact oxidation and liquid intrusion, resulting in high failure rates, especially in industrial or outdoor environments; and stress concentration issues, as traditional adapters often feature right-angle transitions at the interface-to-wire connection, causing stress concentration at the base during bending, leading to wire breakage. Utility Model Content

[0003] To address the aforementioned problems, the primary objective of this utility model is to provide an adapter that solves the technical problem of insufficient protection of the adapter interface in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model provides an adapter, comprising:

[0006] A first mating part, a second mating part, and a third mating part, which together form a cover; wherein...

[0007] The first mating part is used to fully cover the first interface of the workpiece to be processed;

[0008] The third mating part is used to partially cover the second interface of the workpiece to be processed.

[0009] By completely encasing the main body of the workpiece in a cover, a continuous and stable mechanical support is formed. This allows stress to be distributed across the cover rather than the interface when the adapter is bent, reducing the breakage rate. The first mating part fully covering the first interface of the workpiece effectively prevents dust or liquid intrusion, reducing mechanical wear during insertion and removal, and minimizing electromagnetic interference. The third mating part partially encasing the second interface of the workpiece reduces the adapter's weight and size, optimizing convenience, while retaining the interface portion for heat dissipation. Furthermore, the first mating part can be designed as a standardized full-coverage unit; the third mating part can be customized based on the second interface shape; by changing the shape of the third mating part, adapters adapted to new interfaces can be quickly developed; the first and third mating parts can be molded independently, reducing the yield rate issues associated with complex one-piece molding; and the design of the third mating part partially covering the second interface reduces the amount of metal shielding layer or wear-resistant material used.

[0010] Furthermore, it also includes:

[0011] A first connecting portion is disposed between the first mating portion and the second mating portion; wherein...

[0012] The first mating part and the first connecting part are connected to form a first oblique cut structure.

[0013] The first mating part and the first connecting part form a first oblique structure, which provides stable mechanical support, effectively dispersing external stresses such as bending and pulling, reducing the risk of breakage at the connection, and extending the service life of the adapter. The first mating part, the second mating part, and the third mating part form a cover, and the first oblique structure formed between the first mating part and the first connecting part simplifies the assembly process, ensures that all components fit tightly, and reduces tolerance sensitivity.

[0014] Furthermore, the angle of the first oblique cut structure is 90° to 180°.

[0015] By designing the angle of the first oblique cut structure to be 90° to 180°, a gradual mechanical transmission path is formed at the junction of the first mating part and the first connecting part. Compared with right-angle connection, this reduces local stress concentration during bending and reduces the risk of fracture at the root of the interface. The first oblique cut structure is used as a self-aligning structure, which can naturally assemble a guiding reference to ensure the precise alignment of the first mating part and the first connecting part.

[0016] Furthermore, it also includes:

[0017] The outer shell covers the outer peripheral surfaces of the first mating part, the first connecting part, and the second mating part.

[0018] Furthermore, it also includes:

[0019] A first bushing is disposed between the cover and the outer shell;

[0020] The second bushing wraps around the outer peripheral surface of the third mating part and abuts against the first bushing.

[0021] By placing the first bushing between the cover and the outer shell, and the second bushing wrapping around the outer peripheral surface of the third mating part and mating with the first bushing, the gap is filled and the internal structure is fixed to prevent loosening, while enhancing the overall waterproof and dustproof performance.

[0022] Furthermore, the cover is an iron structural component.

[0023] The enclosure is made of iron structure and forms a closed magnetic circuit with the bushing, which significantly suppresses electromagnetic interference during signal transmission inside the adapter, improves the stability of high-speed data transmission, and reduces signal attenuation.

[0024] Furthermore, the outer shell is a plastic structural component.

[0025] Furthermore, both the first bushing and the second bushing are plastic structural components.

[0026] The outer shell is made of plastic to reduce weight, while key internal components such as the cover use iron structural parts, and the first and second bushings use plastic structural parts to ensure strength, achieving a balance between lightweight and high cost performance.

[0027] The composite structure, consisting of a cover, a first bushing, a second bushing, and an outer shell, combines pressure and deformation resistance with shock absorption, making it particularly suitable for high-frequency plugging and unplugging or use in harsh environments.

[0028] Furthermore, the first interface is a USB interface, and the first mating part completely covers the first interface; the second interface is a TYPE-C interface, and the third mating part partially covers the second interface.

[0029] Compared with the prior art, the beneficial effects of this application are as follows: The adapter includes a first mating part, a second mating part, and a third mating part, which together form a cover. The first mating part is used to fully cover the first interface of the workpiece to be processed; the third mating part is used to partially cover the second interface of the workpiece to be processed. By completely enveloping the body of the workpiece with the cover, the adapter can form a continuous and stable mechanical support, distributing stress on the cover rather than at the interface when the adapter is bent, thus reducing the breakage rate. The first mating part's full coverage of the first interface of the workpiece effectively prevents dust or liquid intrusion, reducing mechanical wear during insertion and removal, and reducing electromagnetic interference. The third mating part's partial coverage of the second interface of the workpiece reduces the weight and size of the adapter, optimizing convenience, while retaining the exposed interface portion for heat dissipation. In addition, the first mating part can be designed as a standardized full-coverage part; the third mating part is based on the shape of the second interface; by replacing the third mating part with different shapes, adapters adapted to new interfaces can be quickly developed; the first mating part and the third mating part can be molded independently, reducing the yield problem of complex one-piece molding; the design of the third mating part partially covering the second interface reduces the amount of metal shielding layer or wear-resistant material used.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To achieve the above objectives, the technical solution of this utility model is as follows:

[0037] See Figures 1-4 As shown, this utility model provides an adapter, including: a first mating part 10, a second mating part 20, and a third mating part 30, the first mating part 10, the second mating part 20 and the third mating part 30 forming a cover 60; wherein, the first mating part 10 is used to fully cover the first interface 11 of the workpiece 1 to be processed; the third mating part 30 is used to partially cover the second interface 12 of the workpiece 1 to be processed.

[0038] Thus, in this adapter, the first mating part 10, the second mating part 20, and the third mating part 30 enclose and form a cover 60. By the cover 60 completely enclosing the main body of the workpiece 1, a continuous and stable mechanical support can be formed, so that when the adapter is bent, the stress is distributed in the cover 60 rather than at the interface, which can reduce the breakage rate. By the first mating part 10 completely covering the first interface 11 of the workpiece 1, dust or liquid can be effectively prevented from entering, reducing mechanical wear during insertion and removal, and reducing electromagnetic interference. By the third mating part 30 partially enclosing the second interface 12 of the workpiece 1, the weight and volume of the adapter can be reduced, achieving convenience optimization, and the interface part is left exposed for heat dissipation. In addition, the first mating part 10 can be designed as a standardized full-coverage part; the third mating part 30 is based on the shape of the second interface 12; by replacing the third mating part 30 with different shapes, adapters adapted to new interfaces can be quickly developed; the first mating part 10 and the third mating part 30 can be molded independently, reducing the yield problem of complex one-piece molding; the design of the third mating part 30 partially covering the second interface 12 reduces the amount of metal shielding layer or wear-resistant material used.

[0039] It should be noted that the workpiece 1 to be processed includes a first interface 11, a second interface 12, and a PCB board 13, with the PCB board 13 connected between the first interface 11 and the second interface 12. The first interface 11 is preferably a USB interface, and the second interface 12 is preferably a Type-C interface. In other preferred embodiments, the first interface 11 is a Type-C interface, and the second interface 12 is a USB interface.

[0040] Furthermore, the first interface 11 is a USB interface, and the first mating part 10 completely covers the first interface 11; the second interface 12 is a TYPE-C interface, and the third mating part 30 partially covers the second interface 12.

[0041] Furthermore, the adapter of this application also includes: a first connecting portion 40, disposed between the first mating portion 10 and the second mating portion 30; wherein the first mating portion 10 and the first connecting portion 40 are connected to form a first oblique cut structure. The first oblique cut structure formed by the first mating portion 10 and the first connecting portion 40 provides stable mechanical support, effectively dispersing external stresses such as bending and pulling, reducing the risk of breakage at the connection point, and extending the adapter's service life. The first mating portion 10, the second mating portion 20, and the third mating portion 30 together form a cover, which, combined with the first oblique cut structure of the first connecting portion 40, simplifies the assembly process, ensures tight fit of all components, and reduces tolerance sensitivity.

[0042] Furthermore, the angle of the first oblique cut structure is 90° to 180°.

[0043] Furthermore, an arc-shaped portion 41 is provided between the first connecting portion 40 and the first mating portion 10 for smooth transition.

[0044] By designing the angle of the first beveled structure to be 90° to 180°, a gradual mechanical transmission path is formed at the junction of the first mating part 10 and the first connecting part 40. Compared with a right-angle connection, this reduces local stress concentration during bending and reduces the risk of breakage at the root of the interface. The first beveled structure is used as a self-aligning structure, which can naturally assemble a guiding reference and ensure the precise alignment of the first mating part 10 and the first connecting part 40.

[0045] Furthermore, the adapter also includes a housing 70, which covers the outer peripheral surfaces of the first mating part 10, the first connecting part 40, and the second mating part 20.

[0046] Furthermore, the adapter also includes: a first bushing 81 disposed between the cover 60 and the outer shell 70; and a second bushing 82 wrapped around the outer peripheral surface of the third mating part 30 and mating with the first bushing 81.

[0047] By placing the first bushing 81 between the cover 60 and the outer shell 70, and the second bushing 82 wrapping around the outer peripheral surface of the third mating part 30 and mating with the first bushing 81, the gap is filled and the internal structure is fixed to prevent loosening, while enhancing the overall waterproof and dustproof performance.

[0048] Furthermore, the cover 60 is a steel structural component. The cover 60, being a steel structural component, forms a closed magnetic circuit with the first bushing 81 and the second bushing 82, significantly suppressing electromagnetic interference during signal transmission within the adapter, improving the stability of high-speed data transmission, and reducing signal attenuation.

[0049] Furthermore, the outer shell 70 is a plastic structural component.

[0050] Furthermore, the first bushing 81 and the second bushing 82 are plastic structural components.

[0051] The outer shell 70 is made of plastic to reduce weight, while key internal components such as the cover 60 use iron structural parts, and the first bushing 81 and the second bushing 82 use plastic structural parts to ensure strength, achieving a balance between lightweight and cost-effectiveness. The cover 60, the first bushing 81, the second bushing 82 and the outer shell 70 form a composite structure that combines pressure and deformation resistance with shock absorption, making it especially suitable for high-frequency plugging and unplugging or use in harsh environments.

[0052] The adapter forms a first oblique-cut structure with the first mating part 10 and the first connecting part 40, creating stable mechanical support and effectively dispersing external stresses such as bending and pulling, reducing the risk of breakage at the connection point and extending the adapter's service life. The first oblique-cut structure optimizes mechanical distribution, and combined with a composite shielding layer of metal and plastic, it offers significant advantages in bending resistance, interference resistance, ease of assembly, and cost control. This adapter is suitable for high-power fast charging and high-speed data transmission scenarios, and is particularly suitable for industrial equipment, automotive systems, and other fields with stringent requirements for durability and interference resistance.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
