Description

Technical Field

[0001] This application belongs to the technical field of connectors, and particularly relates to a Type-C interface and an electronic device. Background Art

[0002] To endow an electronic device with waterproof characteristics, a waterproof structure is provided for the Type-C interface in the electronic device. An existing waterproof structure for a Type-C interface is to sleeved a plastic frame on the inner shell. The rear end of the plastic frame abuts against the outer shell and is fixed by dotting glue. A waterproof silicone ring is installed at the front end of the plastic frame, and the connection between the outer shell of the electronic device and the Type-C interface is sealed through the waterproof silicone ring. However, the injection molding process results in a relatively large size of the plastic frame, and the plastic frame occupies a large space inside the electronic device, making it difficult to be applied to electronic devices with a relatively small internal space such as mobile phone chargers. Utility Model Content

[0003] The purpose of the embodiments of this application is to provide a Type-C interface and an electronic device to solve the technical problem that the waterproof structure of the existing Type-C interface occupies a large space inside the electronic device.

[0004] To achieve the above purpose, in a first aspect, the embodiments of this application provide a Type-C interface, including: an inner shell extending along a first direction, with a first limiting flange provided at one end of the inner shell along the first direction, the first limiting flange being arranged around the first direction and protruding outward from the inner shell; an outer shell extending along the first direction, the outer shell being sleeved on the inner shell, with a second limiting flange provided at one end of the outer shell along the first direction close to the first limiting flange, the second limiting flange being arranged around the first direction and protruding outward from the outer shell, and the second limiting flange and the first limiting flange being spaced apart in the first direction; a sealing ring sleeved on the inner shell, and two side surfaces of the sealing ring along the first direction respectively abut against the first limiting flange and the second limiting flange.

[0005] In some embodiments, the size of the second limiting flange protruding outward from the outer shell is greater than the size of the first limiting flange protruding outward from the inner shell.

[0006] In some embodiments, the first limiting flange is formed by flanging the end of the inner shell, and / or the second limiting flange is formed by flanging the end of the outer shell.

[0007] In some embodiments, the inner shell has a first joint seam, and the outer shell has a second joint seam, and the first joint seam and the second joint seam are arranged in a staggered manner.

[0008] In some embodiments, the first joint seam and the second joint seam are respectively located on opposite sides of the Type-C interface.

[0009] In some embodiments, the inner shell has a first seam, the width of the first seam being less than or equal to 0.03 mm, and / or the outer shell has a second seam, the width of the second seam being less than or equal to 0.03 mm.

[0010] In some embodiments, the wall thickness of the inner shell is 0.2 mm - 0.3 mm, and / or the wall thickness of the outer shell is 0.2 mm - 0.3 mm.

[0011] In some embodiments, the Type-C interface further includes a rubber core disposed in the inner shell. An annular sealing flange is provided on the rubber core and is arranged around the first direction. The annular sealing flange is in interference fit with the inner shell to seal between the rubber core and the inner shell.

[0012] In some embodiments, there are at least two annular sealing flanges arranged at intervals along the first direction.

[0013] In a second aspect, an embodiment of the present application further provides an electronic device, including a housing and the Type-C interface according to any one of the embodiments in the first aspect.

The sealing ring is disposed in the sealing hole and is in sealing cooperation with the conical sealing surface.

[0014] The beneficial effects of the present application are as follows: The first limiting flange and the second limiting flange can limit the sealing ring, so that the sealing ring can be installed between the first limiting flange and the second limiting flange; the first limiting flange and the second limiting flange are smaller in size and occupy less space in the electronic device, solving the technical problem that the waterproof structure of the Type-C interface in the prior art occupies a large space in the electronic device. The Type-C interface is easily applicable to electronic devices with a small internal space such as mobile phone chargers.

[0015] Meanwhile, when the sealing ring is in sealing cooperation with the outer shell of the electronic device, the second limiting flange can better limit the position of the sealing ring in the first direction, making the sealing ring deform more in the direction perpendicular to the first direction, so that the pressing force between the sealing ring and the outer shell of the charger is greater and the contact is closer, improving the sealing effect between the sealing ring and the outer shell of the charger.

[0029] An embodiment of the first aspect of this application provides a Type-C interface for electronic devices such as chargers, mobile phones, and computers.

[0030] In the first aspect, an embodiment of this application provides a Type-C interface. Please refer to Figure 1 , the Type-C interface 10 includes an inner shell 11, an outer shell 12, and a sealing ring 15; the inner shell 11 extends along a first direction X, and one end of the inner shell 11 along the first direction X is provided with a first limiting flange 13, and the first limiting flange 13 is arranged around the first direction X and protrudes outward from the inner shell 11; the outer shell 12 extends along the first direction X, the outer shell 12 is sleeved on the inner shell 11, and one end of the outer shell 12 along the first direction X close to the first limiting flange 13 is provided with a second limiting flange 14, and the second limiting flange 14 is arranged around the first direction X and protrudes outward from the outer shell 12, and the second limiting flange 14 and the first limiting flange 13 are spaced apart in the first direction X; the sealing ring 15 is sleeved on the inner shell 11, and two side surfaces of the sealing ring 15 along the first direction X are respectively abutted against the first limiting flange 13 and the second limiting flange 14.

[0031] The inner shell 11 is a ring-shaped structure. It can be understood that the inner shell 11 extends along the first direction X, that is, the center line of the inner shell 11 extends along the first direction X; the inner shell 11 is used to support the outer shell 12 and the sealing ring 15.

[0032] It can be understood that the first limiting flange 13 is arranged around the first direction X, that is, the first limiting flange 13 is arranged along the circumferential direction of the inner shell 11; the first limiting flange 13 protrudes outward, that is, the first limiting flange 13 protrudes in the radial direction of the inner shell 11 away from the center line of the inner shell 11.

[0033] The first limiting flange 13 can be ring-shaped or can be set as a C shape; a plurality of first limiting flanges 13 can be arranged around the first direction X. The first limiting flange 13 can be welded on the inner shell 11 or can be formed by flanging the inner shell 11.

[0034] The outer shell 12 is annular and the center line of the outer shell 12 extends along the first direction X. The inner shell 11 is fixedly connected to the outer shell 12. Optionally, the outer shell 12 is fixed to the inner shell 11 by laser spot welding. When the outer shell 12 is heated by laser, the heat is conducted to the inner shell 11, and the inner shell and the outer shell are melted and connected together, so that the inner shell 11 and the outer shell 12 are stably connected, and the influence on the overall support strength of the Type-C interface 10 can be reduced.

[0035] It can be understood that the second limiting flange 14 is arranged around the first direction X, that is, the second limiting flange 14 is arranged along the circumferential direction of the outer shell 12; the second limiting flange 14 protrudes outwards, that is, the second limiting flange 14 protrudes in the radial direction of the outer shell 12 away from the center line of the outer shell 12.

[0036] The second limiting flange 14 can be annular or can be arranged in a C shape; a plurality of second limiting flanges 14 can be arranged around the first direction X. The second limiting flange 14 can be welded to the outer shell 12 or can be formed by flanging the outer shell 12.

[0037] The second limiting flange 14 and the first limiting flange 13 are arranged at intervals in the first direction X and form an annular groove with the inner shell 11; the sealing ring 15 is arranged in the groove; in the direction perpendicular to the first direction X, the size of the sealing ring 15 is larger than the size of the first limiting flange 13, so that the part of the sealing ring 15 exceeding the first limiting flange 13 can be in contact with the housing of the electronic device. The direction perpendicular to the first direction X is a plurality of directions perpendicular to the first direction X.

[0038] When the sealing ring 15 is in sealing fit with the housing of the electronic device, the first limiting flange 13 and the second limiting flange 14 are used to limit the position of the sealing ring 15 in the first direction X, and the sealing ring 15 is squeezed and mainly deforms in the direction perpendicular to the first direction X. Optionally, the sealing ring 15 is a waterproof silica gel ring.

[0039] The beneficial effects of this embodiment are as follows: the first limiting flange 13 and the second limiting flange 14 can limit the sealing ring 15, so that the sealing ring 15 can be installed between the first limiting flange 13 and the second limiting flange 14; the first limiting flange 13 and the second limiting flange 14 can be formed by processes such as flanging or welding, and have a small size, occupying a small space inside the electronic device, solving the technical problem that the waterproof structure of the Type-C interface 10 in the prior art occupies a large space inside the electronic device. The Type-C interface 10 is easily applicable to electronic devices with a small internal space such as mobile phone chargers, and can achieve IPx2 domestic waterproofing in the charger.

[0040] At the same time, please refer to Figure 4, when the sealing ring 15 is in sealing fit with the housing 20 of the electronic device 100, the second limiting flange 14 can better limit the position of the sealing ring 15 in the first direction X, making the sealing ring 15 deform more in the direction perpendicular to the first direction X, so that the pressing force between the sealing ring 15 and the housing 20 of the electronic device 100 is greater and the contact is closer, improving the sealing effect between the sealing ring 15 and the housing 20 of the electronic device 100.

[0041] In some embodiments, please refer to Figures 2 to 4 , the dimension that the second limiting flange 14 protrudes outward from the outer shell 12 is greater than the dimension that the first limiting flange 13 protrudes outward from the inner shell 11.

[0042] It can be understood that the dimension by which the second limiting flange 14 protrudes refers to the dimension protruding from the outer wall surface of the outer shell 12, and the dimension by which the first limiting flange 13 protrudes refers to the dimension protruding from the outer wall surface of the inner shell 11.

[0043] The beneficial effect of this embodiment is that in the direction perpendicular to the first direction X, the second limiting flange 14 is set longer. When the sealing ring 15 is in sealing fit with the housing 20 of the electronic device 100, the second limiting flange 14 can better hold the sealing ring 15, better limit the position of the sealing ring 15 in the first direction X, making the sealing ring 15 deform more in the direction perpendicular to the first direction X, and the pressing force between the sealing ring 15 and the housing 20 of the electronic device 100 is greater and the contact is closer, further improving the sealing effect between the sealing ring 15 and the housing 20 of the electronic device 100.

[0044] In other embodiments, the dimension that the second limiting flange 14 protrudes outward from the outer shell 12 is less than or equal to the dimension that the first limiting flange 13 protrudes outward from the inner shell 11.

[0045] In some embodiments, please refer to Figure 3 , the first limiting flange 13 is formed by flanging the end of the inner shell 11; the second limiting flange 14 is formed by flanging the end of the outer shell 12.

[0046] It can be understood that after the inner shell 11 is formed, the edge of the inner shell 11 is stamped and flanged to form the first limiting flange 13, and the first limiting flange 13 and the inner shell 11 are of an integral structure.

[0047] It can be understood that after the outer shell 12 is formed, the edge of the outer shell 12 is stamped and flanged to form the second limiting flange 14, and the second limiting flange 14 and the outer shell 12 are of an integral structure.

[0048] The beneficial effects of this embodiment are as follows: Flanging on the inner shell 11 can form a first limiting flange 13 with a relatively small size, and flanging on the outer shell 12 can form a second limiting flange 14 with a relatively small size, which can reduce the space occupied by the Type-C interface 10 in the electronic device. It is defined that the first limiting flange 13 is in front of the second limiting flange 14. The flanged first limiting flange 13 is located at the forefront of the inner shell 11, and the sealing ring 15 can be arranged forward, so that the sealing ring 15 can be adapted to the sealing structure at the front end inside the electronic device, reducing the space occupied in the middle of the electronic device.

[0049] In other embodiments, the first limiting flange 13 and the inner shell 11 are of a split structure, and the first limiting flange 13 is fixed (which can be but is not limited to welding) on the inner shell 11. The second limiting flange 14 and the outer shell 12 are of a split structure, and the second limiting flange 14 is fixed (which can be but is not limited to welding) on the outer shell 12; or, the first limiting flange 13 and the inner shell 11 are of a split structure, and the first limiting flange 13 is fixed (which can be but is not limited to welding) on the inner shell 11, and the second limiting flange 14 is formed by flanging the end of the outer shell 12; or, the first limiting flange 13 is formed by flanging the end of the inner shell 11, the second limiting flange 14 and the outer shell 12 are of a split structure, and the second limiting flange 14 is fixed (which can be but is not limited to welding) on the outer shell 12.

[0050] In some embodiments, please refer to Figure 1 , the inner shell 11 has a first joint 111, the outer shell 12 has a second joint 121, and the first joint 111 and the second joint 121 are arranged in a staggered manner.

[0051] It can be understood that both the inner shell 11 and the outer shell 12 are formed by bending metal plates, and the first joint 111 and the second joint 121 are the joints at the splicing parts after the two ends of the plates are bent. Optionally, the inner shell 11 and the outer shell 12 are formed by stamping.

[0052] It can be understood that the first joint 111 and the second joint 121 can be respectively located on the opposite sides of the Type-C interface 10. Optionally, the first joint 111 and the second joint 121 can be arranged at 180° with respect to the center line of the inner shell 11; or, the first joint 111 and the second joint 121 can be respectively located on the adjacent sides of the Type-C interface 10. Optionally, the first joint 111 and the second joint 121 can be arranged at 90° with respect to the center line of the inner shell 11; or, the first joint 111 and the second joint 121 can be located on the same side of the Type-C interface 10. Optionally, the first joint 111 and the second joint 121 can be arranged at 20° with respect to the center line of the inner shell 11.

[0053] The beneficial effects of this embodiment are as follows: The first seam 111 and the second seam 121 are arranged in a staggered manner, that is, the first seam 111 and the second seam 121 are not aligned, making it difficult for the water in the inner shell 11 to flow from the first seam 111 to the second seam 121, reducing the risk of the water in the inner shell 11 flowing into the electronic device through the first seam 111 and the second seam 121, and improving the waterproof effect of the Type-C interface 10.

[0054] In other embodiments, the inner shell 11 or the outer shell 12 is formed by stamping to stretch the metal, and there is no seam on the inner shell 11 or the outer shell 12.

[0055] In some embodiments, please refer to Figure 1 , the first seam 111 and the second seam 121 are respectively located on opposite sides of the Type-C interface 10.

[0056] Optionally, the first seam 111 and the second seam 121 are arranged at 180° with respect to the center line of the inner shell 11, so that the distance between the first seam 111 and the second seam 121 in the circumferential direction of the Type-C interface 10 is farther.

[0057] The beneficial effects of this embodiment are as follows: The first seam 111 and the second seam 121 are respectively located on opposite sides of the Type-C interface 10, so that the distance between the first seam 111 and the second seam 121 in the circumferential direction of the Type-C interface 10 is farther, further increasing the difficulty of water flowing from the first seam 111 to the second seam 121, reducing the risk of the water in the inner shell 11 flowing into the electronic device, and improving the waterproof effect of the Type-C interface 10.

[0058] In some embodiments, the inner shell 11 has a first seam 111, and the width of the first seam 111 is less than or equal to 0.03 mm; the outer shell 12 has a second seam 121, and the width of the second seam 121 is less than or equal to 0.03 mm.

[0059] Optionally, the width of the first seam 111 is 0.03 mm or 0.02 mm.

[0060] Optionally, the width of the second seam 121 is 0.03 mm or 0.02 mm.

[0061] The beneficial effects of this embodiment are as follows: The width of the first seam 111 is less than or equal to 0.03 mm, making it difficult for the water in the inner shell 11 to flow from the first seam 111 to between the inner shell 11 and the outer shell 12. The width of the second seam 121 is less than or equal to 0.03 mm, making it difficult for the water between the inner shell 11 and the outer shell 12 to flow into the electronic device through the second seam 121, and the waterproof effect of the Type-C interface 10 can be improved.

[0062] In other embodiments, the width of the first seam 111 is less than or equal to 0.03 mm, and the width of the second seam 121 is greater than 0.03 mm; alternatively, the width of the first seam 111 is greater than 0.03 mm, and the width of the second seam 121 is less than or equal to 0.03 mm; alternatively, the width of the first seam 111 is greater than 0.03 mm, and the width of the second seam 121 is greater than 0.03 mm.

[0063] In some embodiments, the wall thickness of the inner shell 11 is 0.2 mm - 0.3 mm.

[0064] Optionally, the wall thickness of the inner shell 11 is 0.2 mm, 0.25 mm or 0.3 mm.

[0065] The beneficial effect of this embodiment is that: the wall thickness of the inner shell 11 is 0.2 mm - 0.3 mm, and on the basis of ensuring the strength of the inner shell 11, the wall thickness can be minimized as much as possible, thereby reducing the flanging size of the inner shell 11, and the first limiting flange 13 can be controlled within a smaller size, reducing the volume of the Type-C interface 10.

[0066] In other embodiments, the wall thickness of the inner shell 11 is 0.15 mm - 0.2 mm.

[0067] In some embodiments, the wall thickness of the outer shell 12 is 0.2 mm - 0.3 mm.

[0068] Optionally, the wall thickness of the outer shell 12 is 0.2 mm, 0.25 mm or 0.3 mm.

[0069] The beneficial effect of this embodiment is that: the wall thickness of the outer shell 12 is 0.2 mm - 0.3 mm, and on the basis of ensuring the strength of the outer shell 12, the wall thickness can be minimized as much as possible, thereby reducing the flanging size of the outer shell 12, and the second limiting flange 14 can be controlled within a smaller size, reducing the volume of the Type-C interface 10.

[0070] In some embodiments, please refer to Figure 2 and Figure 3 , the Type-C interface 10 further includes a rubber core 16 disposed in the inner shell 11. An annular sealing flange 17 is provided on the rubber core 16 and is arranged around the first direction X. The annular sealing flange 17 is in interference fit with the inner shell 11 to seal between the rubber core 16 and the inner shell 11.

[0071] The rubber core 16 is used to install conductive PINs so that the Type-C interface 10 can be electrically connected to an external Type-C male interface through the conductive PINs. The rubber core 16 extends along the first direction X. The cross-section of the rubber core 16 at the end away from the first limiting flange 13 is larger than the cross-section of the rubber core 16 at the end close to the first limiting flange 13, and the annular sealing flange 17 is disposed at the end of the rubber core 16 away from the first limiting flange 13.

[0072] It can be understood that the annular sealing flange 17 is in interference fit with the inner shell 11, that is, in the direction perpendicular to the first direction X, the size of the annular sealing flange 17 is greater than the distance between the inner shell 11 and the rubber core 16, so that the annular sealing flange 17 presses against the inner shell 11, making the annular sealing flange 17 in close contact with the inner shell 11, and sealing between the rubber core 16 and the inner shell 11. Optionally, the interference amount between the annular sealing flange 17 and the inner shell 11 is 0.02 - 0.03 mm. Optionally, the annular sealing flange 17 and the rubber core 16 are integrally formed.

[0073] The beneficial effect of this embodiment is that by providing the annular sealing flange 17 on the rubber core 16, the sealing performance between the rubber core 16 and the inner shell 11 can be improved, the risk of water in the inner shell 11 flowing into the electronic device between the rubber core 16 and the inner shell 11 can be reduced, and the waterproof effect of the Type-C interface 10 can be improved.

[0074] In other embodiments, the rubber core 16 has an annular groove provided around the first direction X, and a waterproof sealing ring is provided in the annular groove. The waterproof sealing ring is in interference fit with the inner shell 11 to seal between the rubber core 16 and the inner shell 11.

[0075] In some embodiments, please refer to Figure 2 and Figure 3 , there are at least two annular sealing flanges 17 arranged at intervals along the first direction X.

[0076] It can be understood that two annular sealing flanges 17 can be provided along the first direction X, or more than two can be provided, and there is a gap between adjacent two flanges.

[0077] The beneficial effect of this embodiment is that providing multiple annular sealing flanges 17 can further improve the sealing performance between the rubber core 16 and the inner shell 11 and improve the waterproof effect of the Type-C interface 10.

[0078] In some embodiments, please refer to Figures 1 to 3 , the Type-C interface 10 includes an inner shell 11, an outer shell 12, a sealing ring 15 and a rubber core 16; the inner shell 11 extends along the first direction X, and a first limiting flange 13 is provided at one end of the inner shell 11 along the first direction X. The first limiting flange 13 is provided around the first direction X and protrudes outward; the outer shell 12 extends along the first direction X, the outer shell 12 is sleeved on the inner shell 11, and a second limiting flange 14 is provided at one end of the outer shell 12 along the first direction X close to the first limiting flange 13. The second limiting flange 14 is provided around the first direction X and protrudes outward. The second limiting flange 14 and the first limiting flange 13 are arranged at intervals in the first direction X; the sealing ring 15 is sleeved on the inner shell 11, and both side surfaces of the sealing ring 15 along the first direction X are in contact with the first limiting flange 13 and the second limiting flange 14 respectively.

[0079] The first limiting flange 13 and the second limiting flange 14 are annularly arranged around the first direction X. In the direction perpendicular to the first direction X, the size of the second limiting flange 14 is larger than that of the first limiting flange 13.

[0080] The first limiting flange 13 is formed by flanging the inner shell 11, and the second limiting flange 14 is formed by flanging the outer shell 12. Both the inner shell 11 and the outer shell 12 are formed by bending plate-shaped metal. The inner shell 11 includes a first joint 111, and the outer shell 12 includes a second joint 121. The first joint 111 and the second joint 121 are arranged in a staggered manner.

[0081] The rubber core 16 extends along the first direction X. Two annular sealing flanges 17 are arranged on the rubber core 16. The annular sealing flanges 17 are arranged around the first direction X and are spaced along the first direction X. The annular sealing flanges 17 are in interference fit with the inner shell 11 to seal between the rubber core 16 and the inner shell 11; The overall process of the Type-C interface 10 is simple and mature, with low cost and high cost performance.

[0082] In a second aspect, the embodiments of the present application further provide an electronic device. Please refer to Figure 4 , the electronic device 100 includes a housing 20 and the Type-C interface 10 according to any one of the embodiments of the first aspect. The Type-C interface 10 is arranged in the housing 20; A sealing hole 21 extending along the first direction X is arranged in the housing 20. The sealing hole 21 has a conical sealing surface 211. The sealing ring 15 is arranged in the sealing hole 21 and is in sealing cooperation with the conical sealing surface 211.

[0083] One end of the Type-C interface 10 close to the first limiting flange 13 is communicated with the outside of the housing 20. The Type-C male interface can be inserted into the Type-C interface 10 from outside the housing 20.

[0084] The cross-section of the conical sealing surface 211 gradually becomes larger from the first limiting flange 13 to the second limiting flange 14 along the first direction X. In the direction perpendicular to the first direction X, the size of the sealing ring 15 is larger than the distance between one end of the conical sealing surface 211 close to the first limiting flange 13 and the inner shell 11, so that one end of the sealing ring 15 close to the first limiting flange 13 is squeezed and deformed by the conical sealing surface 211 and the inner shell 11, so that the sealing ring 15 is in close contact with the inner shell 11 and the conical sealing surface 211, and the sealing ring 15 is sealed between the inner shell 11 and the conical sealing surface 211 respectively.

[0085] The beneficial effects of this embodiment are as follows: The conical sealing surface 211 can guide the Type-C interface 10 into the sealing hole 21 and be centered in the sealing hole 21, which is beneficial to the assembly guidance of the Type-C interface 10; through the sealing cooperation between the conical sealing surface 211 and the sealing ring 15, a sealing structure is formed between the sealing hole 21 of the housing 20 and the Type-C interface 10, reducing the risk of water entering the housing 20 from between the Type-C interface 10 and the sealing hole 21, and improving the waterproof effect of the electronic device 100. Using the above-mentioned Type-C interface 10 in the electronic device 100 can occupy less space inside the housing 20, facilitating the design of the internal structure of the housing 20 of electronic devices 100 with a relatively small internal space, such as mobile phone chargers, and enabling the electronic device 100 to easily achieve IPx2 waterproof for daily use.

[0086] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
