Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technology, specifically relating to a waterproof ring and an electronic device. Background Technology
[0002] As users increasingly demand the best user experience, electronic devices are becoming more feature-rich. Consequently, the number of functional components within these devices is also increasing, leading to more circuit board-to-circuit connections and a greater variety of functional devices between them. For example, board-to-board connectors, a common functional device, connect two circuit boards to enable data transmission between them. To prevent external water from entering the electronic device through these board-to-board connector functional devices, a waterproof ring is typically installed around the functional device, which abuts against the two circuit boards.
[0003] In prior art, electronic devices generate radio frequency (RF) signals during RF communication, which can easily interfere with the signal transmission of functional devices. To prevent electromagnetic interference, conductive cloth is typically used to wrap board-to-board connectors.
[0004] However, wrapping board-to-board connectors with conductive cloth not only fails to achieve waterproofing, causing short circuits, but also makes the process difficult due to the limited space between adjacent circuit boards. In other words, existing technologies struggle to simultaneously provide waterproofing and electromagnetic shielding for board-to-board connectors. Summary of the Invention
[0005] This application aims to provide a waterproof ring and an electronic device to solve the problem that existing waterproof rings are difficult to simultaneously achieve waterproofing and electromagnetic shielding.
[0006] To solve the above-mentioned technical problems, this application is implemented as follows:
[0007] In a first aspect, this application discloses a waterproof ring, the waterproof ring comprising: a ring-shaped body, the ring-shaped body comprising a plurality of deformation units, each deformation unit having a conductive element disposed therein, and adjacent deformation units being insulated from each other; wherein...
[0008] The plurality of deformation units are distributed in a cross-sectional array perpendicular to the axis of the circular body.
[0009] Secondly, this application also discloses an electronic device, which includes: a first circuit board, a second circuit board, functional components, and a waterproof ring as described in any one of the above claims; wherein,
[0010] The first circuit board and the second circuit board are arranged at a relative interval;
[0011] The functional device is connected between the first circuit board and the second circuit board;
[0012] The waterproof ring is fitted over the functional device, and the ring-shaped body of the waterproof ring abuts against the first circuit board and the second circuit board respectively. The conductive part of the waterproof ring is electrically connected to the first circuit board and the second circuit board respectively.
[0013] In this embodiment, the ring-shaped body can be sleeved around the functional device. Since the ring-shaped body can include multiple deformation units, the deformation of these units achieves a sealed and waterproof effect for the functional device. Because each deformation unit contains a conductive element, and adjacent deformation units are insulated from each other, the mutually insulated conductive elements within the multiple deformation units achieve electromagnetic shielding. That is, the waterproof ring can simultaneously provide waterproof protection and electromagnetic shielding, and its installation is simple and occupies little space.

[0029] This application provides a waterproof ring that can be used in electronic devices, including at least one of mobile phones, tablets, and wearable devices. This application does not specifically limit the type of electronic device. The electronic device may contain functional components such as board-to-board connectors. The waterproof ring can be fitted over these functional components to provide waterproof protection and electromagnetic shielding.
[0030] Reference Figure 1 The diagram shows a structural schematic of a waterproof ring according to an embodiment of this application. (Refer to...) Figure 2 , showed Figure 1 A detailed structural diagram of the waterproof ring A position is shown.
[0031] like Figure 1 , Figure 2 As shown, the waterproof ring specifically includes a ring-shaped body 10, which includes multiple deformation units 103. Each deformation unit 103 has a conductive element 11 inside, and adjacent deformation units 103 are insulated from each other. The multiple deformation units 103 are distributed in a cross-sectional array along a cross-section perpendicular to the axis 10 of the ring-shaped body.
[0032] In this embodiment, the ring-shaped body 10 can be sleeved around the functional device. Since the ring-shaped body 10 can include multiple deformation units 103, the deformation of these units achieves a sealed and waterproof effect for the functional device. Because each deformation unit 103 contains a conductive element 11, and adjacent deformation units 103 are insulated from each other, the mutually insulated conductive elements 11 within the multiple deformation units 103 achieve electromagnetic shielding. That is, the waterproof ring can simultaneously provide waterproof protection and electromagnetic shielding, and its installation is simple and occupies little space.
[0033] Specifically, the circular body 10 has a cavity 101 inside, which can be used to accommodate functional devices. These functional devices may include board-to-board connectors, photosensitive sensors, power supplies, etc. This embodiment only uses a board-to-board connector as an example; other types of functional devices can be described similarly. In practical applications, the shapes of the circular body 10 and the cavity 101 can be determined according to the shape of the functional device to facilitate fitting the circular body 10 around the functional device and improve their fit.
[0034] For example, such as Figure 1 As shown, when the functional device is a cuboid board-to-board connector, the cross-sectional shapes of the ring-shaped body 10 and the cavity 101 can be similar to rectangles. Alternatively, when the functional device is cylindrical, the cross-sectional shapes of the ring-shaped body 10 and the cavity 101 can be circular. The specific shapes of the ring-shaped body 10 and the cavity 101 are not limited in this embodiment.
[0035] In this embodiment, the deformation unit 103 on the ring-shaped body 10 can deform, and the deformation of the deformation unit 103 can cause the entire ring-shaped body 10 to deform. This deformation of the ring-shaped body 10 facilitates its fitting between two adjacent circuit boards, preventing external water from entering the functional device through the gap between the two adjacent circuit boards, thus achieving waterproof protection for the functional device.
[0036] Furthermore, in this embodiment, the ring-shaped body 10 includes multiple deformation units 103, which are arranged in a cross-sectional array perpendicular to the axis of the ring-shaped body 10. Each deformation unit 103 contains a conductive element 11. Therefore, the conductive elements 11 within the multiple deformation units 103 can form a grid-like conductive channel. Since adjacent deformation units 103 are insulated from each other, adjacent conductive elements 11 can also be correspondingly insulated from each other. Thus, the multiple grid-like conductive elements 11 can form a metal shielding array, achieving electromagnetic shielding.
[0037] In practical applications, the two ends of the conductive element 11 can be electrically connected to two adjacent circuit boards respectively, and one conductive element 11 can form a conductive path between circuit boards. Since multiple conductive elements 11 are provided in the ring-shaped body 10, and adjacent conductive elements 11 are insulated from each other, different conductive elements 11 can be connected to different positions on the circuit board to form conductive paths for different network signals. Moreover, no short circuit is formed between adjacent conductive paths, which can further improve the electromagnetic shielding effect of multiple conductive elements 11.
[0038] Optionally, the conductive element 11 can be perpendicular to the surfaces of two adjacent circuit boards to minimize the distance between the conductive elements 11. Alternatively, the conductive element 11 can also be inclined to the surfaces of two adjacent circuit boards; this embodiment of the application does not limit this.
[0039] In this embodiment, the conductive element 11 can deform, which makes it easier for the conductive element 11 to deform together with the deformation unit 103, thereby further improving the overall waterproof effect of the waterproof ring.
[0040] In some optional embodiments of this application, the conductive element 11 may include a conductive adhesive structure that is deformable. Specifically, the conductive adhesive structure may be made of conductive adhesive. Since conductive adhesive has both electrical conductivity and deformability, when the conductive element 11 is the conductive adhesive structure, it can both conduct electricity and deform with the deformation unit 103.
[0041] Specifically, the conductive adhesive mainly consists of a resin matrix, conductive particles, dispersing additives, and auxiliaries. The matrix primarily includes epoxy resin, acrylate resin, and polyurethane. The conductive particles themselves must possess good conductivity and have a suitable particle size range, enabling them to be added to the conductive adhesive matrix to form conductive pathways. Conductive fillers can be powders of gold, silver, copper, aluminum, zinc, iron, and nickel, as well as graphite and some conductive compounds.
[0042] In some alternative embodiments of this application, the conductive element 11 may include a conductive wire. Since the conductive wire is elastic, when the conductive element 11 is made of conductive wire, the conductive element 11 can be elastically compressed and deformed following the deformation unit 103 to achieve the waterproof effect of the waterproof ring.
[0043] For example, the conductive wire may include, but is not limited to, copper wire, silver wire, etc., and the specific type of the conductive wire may not be limited in the embodiments of this application.
[0044] Optionally, the edge of the deformation unit 103 can be an insulating colloid that is deformable. In specific applications, to achieve deformation of the ring-shaped body 10 and to achieve insulating separation between multiple conductive elements 11, the deformation unit 103 can be made of a deformable insulating material. Specifically, the material of the deformation unit 103 may include at least one of polyurethane rubber, silicone, and foam.
[0045] For example, consider polyurethane rubber as the material of deformation unit 103. Polyurethane rubber is polymerized from polyester (or polyether) and diisocyanate compounds. Its chemical structure is more complex than that of general elastic polymers. In addition to the recurring urethane groups, the molecular chain often contains ester groups, ether groups, aromatic groups, etc. The main molecular chain of polyurethane rubber is composed of flexible and rigid segments; the flexible segments, also known as soft segments, are composed of oligomeric polyols (such as polyester, polyether, polybutadiene, etc.); the rigid segments, also known as hard segments, are composed of the reaction products of diisocyanates (such as TDI, MDI, etc.) and small molecule chain extenders (such as diamines and diols, etc.). Soft segments account for a larger proportion than hard segments. The polarity of soft and hard segments differs; hard segments are more polar and tend to aggregate, forming many micro-phases distributed within the soft segment phase, known as a microphase separation structure. Its physical and mechanical properties are greatly related to the degree of microphase separation. Polyurethane molecules have high strength and elasticity due to hydrogen bonding between their main chains, and they also possess insulating properties.
[0046] It should be noted that, in practical applications, the material of the deformation unit 103 can also be filled with absorbing materials such as oxides to further attenuate electromagnetic interference and improve the signal transmission quality of the functional device.
[0047] Reference Figure 3 The diagram shows a partial structural schematic of a ring-shaped body according to an embodiment of this application. (Refer to...) Figure 4 , showed Figure 3 The enlarged structural diagram of the circular body shown is for reference. Figure 5 , showed Figure 4 The diagram shows the structural schematic of the deformation unit body within the deformation unit. (See attached diagram.) Figure 3 As shown, the circular body 10 is provided with multiple deformation units 103, such as... Figure 4 As shown, the conductive element 11 is embedded within the deformation unit 103. Figure 5 As shown, the deformation unit 103 may include: a deformation unit body 1031, on which a first through hole 102 is provided, and a conductive element 11 may be embedded in the first through hole 102.
[0048] Figure 3 In the circular body 10 shown, since the circular body 10 includes multiple deformation units 103, the conductive element 11 is embedded in the first through hole 102 of the deformation unit 103, and the two adjacent conductive elements 11 are insulated from each other to achieve the effect of electromagnetic shielding. That is, the waterproof ring 23 can simultaneously provide waterproof protection and electromagnetic shielding, and the installation method is simple and occupies little space.
[0049] Optionally, Figure 3In the circular body 10 shown, the deformation unit body 1031 of the multiple deformation units 103 can be an integrally formed structure, and the conductive component 11 can include a conductive adhesive structure.
[0050] In practical applications, multiple deformation unit bodies 1031 of deformation units 103 can be formed simultaneously using methods such as injection molding. These deformation unit bodies 1031 are then processed into a single integral structure, resulting in high connection strength between adjacent deformation units 103. By injecting conductive adhesive into the first through-hole 101 of the deformation unit body 1031, a conductive adhesive structure embedded within the first through-hole 101 can be formed. This processing method is simple, and the connection strength between the conductive adhesive structure and the deformation unit body 1031 is high. Furthermore, because the conductive adhesive is highly elastic and easily deformable, it can reduce the deformation resistance of the waterproof ring, thereby improving its waterproofing effect.
[0051] Reference Figure 6 This shows a schematic diagram of another deformable unit body according to an embodiment of this application. (Refer to...) Figure 7 This shows a kind of Figure 6 The diagram shows the structure of the conductive component used in conjunction with the deformation unit body.
[0052] like Figure 6 As shown, a second through hole 104 is provided inside the deformation unit body 1031. The second through hole 104 can be used for the conductive component 11 to pass through, so as to... Figure 7 The conductive element 11 shown is embedded in the second through hole 104.
[0053] Optionally, Figure 6 The deformation unit body in the deformation unit 103 shown can be a split structure. Figure 7 The conductive element 11 shown can be a conductive wire.
[0054] In practical applications, injection molding can be used to process and form materials such as... Figure 6 The deformable unit body 1031 shown can deform. Then, Figure 7 The conductive element 11 shown is embedded in Figure 6 The deformation unit 103, with a conductive element 11 embedded inside, is obtained within the second through hole 104 of the deformation unit body 1031 shown. Finally, an adhesive is used to bond two adjacent deformation units 103 together. By connecting multiple deformation units 103 into a whole, a deformable ring-shaped body 10 can be formed, and the processing method is extremely simple.
[0055] For example, the material of the adhesive may include, but is not limited to, glue, double-sided tape, etc. The specific material of the adhesive may not be limited in the embodiments of this application.
[0056] Optionally, the boundary shape of the deformation unit 103 can be at least one of honeycomb hexagon, circle and square. This application embodiment does not specifically limit the boundary shape of the deformation unit 103.
[0057] Optionally, the ring-shaped body 10 may include a first side and a second side that are opposite to each other, and the conductive element 11 passes through the first side and the second side, and is at least partially exposed on the first side and the second side, so that the two ends of the conductive element 11 can be connected to two adjacent circuit boards respectively.
[0058] For example, the first side can be the top side of the ring-shaped body 10, and the second side can be the bottom side of the ring-shaped body 10. The first side of the ring-shaped body 10 can be connected to the upper circuit board, and the second side of the ring-shaped body 10 can be connected to the lower circuit board. Since the conductive element 11 extends through the first and second sides and is at least partially exposed on both sides, it facilitates the connection of the portion of the conductive element 11 exposed on the first side to the upper circuit board, and the connection of the portion of the conductive element 11 exposed on the second side to the lower circuit board. This improves the reliability of the electrical connection between the conductive element 11 and the upper and lower circuit boards, thereby enhancing the stability of the electromagnetic shielding effect of the waterproof ring.
[0059] In summary, the waterproof ring described in the embodiments of this application may include at least the following advantages:
[0060] In this embodiment, the ring-shaped body can be sleeved around the functional device. Since the ring-shaped body can include multiple deformation units, the deformation of these units achieves a sealed and waterproof effect for the functional device. Because each deformation unit contains a conductive element, and adjacent deformation units are insulated from each other, the mutually insulated conductive elements within the multiple deformation units achieve electromagnetic shielding. That is, the waterproof ring can simultaneously provide waterproof protection and electromagnetic shielding, and its installation is simple and occupies little space.
[0061] Reference Figure 8 The diagram illustrates the structure of an electronic device according to an embodiment of this application, such as... Figure 8As shown, the electronic device may specifically include: a first circuit board 21, a second circuit board 22, a functional device (not shown in the figure), and a waterproof ring 23 as described in the above embodiments; wherein, the first circuit board 21 and the second circuit board 22 are arranged at intervals relative to each other; the functional device is connected between the first circuit board 21 and the second circuit board 22; the waterproof ring 23 is sleeved on the functional device, the ring-shaped body 10 of the waterproof ring 23 abuts against the first circuit board 21 and the second circuit board 22 respectively, and the conductive part 11 of the waterproof ring 23 is electrically connected to the first circuit board 21 and the second circuit board 22 respectively.
[0062] In this embodiment, the waterproof ring 23 can be fitted over the functional device. Since the ring-shaped body 10 of the waterproof ring 23 can include multiple deformation units 103, the deformation of these units achieves a sealed and waterproof effect on the functional device. Because each deformation unit 103 contains a conductive element 11, and adjacent deformation units 103 are insulated from each other, the mutually insulated conductive elements 11 within the multiple deformation units 103 achieve electromagnetic shielding. That is, the waterproof ring can simultaneously provide waterproof protection and electromagnetic shielding, and its installation is simple and occupies little space.
[0063] For example, the functional device may include board-to-board connectors, photosensitive sensors, power supplies, etc. This application embodiment only uses board-to-board connectors as an example of the functional device for illustration. Other types of functional devices can be implemented by analogy.
[0064] Optionally, a first electrical connection portion 211 is provided on the side of the first circuit board 21 near the second circuit board 22; a second electrical connection portion 221 is provided on the side of the second circuit board 22 near the first circuit board 21; one end of the conductive member 11 is electrically connected to the first electrical connection portion 211, and the other end of the conductive member 11 is electrically connected to the second electrical connection portion 221; the potential difference between the first electrical connection portion 211 and the second electrical connection portion 221 is zero.
[0065] Specifically, since the two ends of the conductive element 11 are electrically connected to the first electrical connection portion 211 and the second electrical connection portion 221 respectively, a conductive path can be formed on the conductive element 11 to achieve electromagnetic shielding for the functional device. The network properties of the contact surfaces of the first electrical connection portion 211 and the conductive element 11 and the second electrical connection portion 221 and the conductive element 11 are consistent, for example, both are GND, or they are from the same power source, to ensure that there is no potential difference between the first electrical connection portion 211 and the second electrical connection portion 221, thus preventing short circuits in the conductive element 11 within the waterproof ring 23.
[0066] For example, the first electrical connection portion 211 may be a portion of exposed copper or a metal sheet on the first circuit board 21. Similarly, the second electrical connection portion 221 may also be a portion of exposed copper or a metal sheet on the second circuit board 22. The specific forms of the first electrical connection portion 211 and the second electrical connection portion 221 are not limited in the embodiments of this application.
[0067] Optionally, the first electrical connection portion 211 is the ground portion of the first circuit board 21, and the second electrical connection portion 221 is the ground portion of the second circuit board 22. This not only ensures that the potential difference between the first electrical connection portion 211 and the second electrical connection portion 221 is zero, but also avoids the need for additional first connection portions on the first circuit board 21 and additional second connection portions on the second circuit board 22 by sharing the ground portions on both circuit boards 21 and 22, thus simplifying the structure of the first circuit board 21 and 22.
[0068] Optionally, the conductive element 11 can be perpendicular to the surfaces of the first circuit board 21 and the second circuit board 22, respectively, so that the length of the conductive element 11 is minimized.
[0069] Optionally, the height of the annular body 10 can be greater than the height of the functional device. This allows the waterproof ring 23 to undergo a certain degree of compression deformation when the functional device is held between the first circuit board 21 and the second circuit board 22. This ensures reliable contact between the conductive element 11 inside the annular body 10 and the first electrical connection portion 211 and the second electrical connection portion 221, improving the reliability of the electromagnetic shielding effect. Furthermore, it facilitates sufficient contact between the waterproof ring 23 and the first circuit board 21 and the second circuit board 22, preventing external water from entering the functional device.
[0070] Optionally, the first circuit board 21 and the second circuit board 22 can be flexible circuit boards or printed circuit boards. The specific contents of the first circuit board 21 and the second circuit board 22 are not limited in the embodiments of this application.
[0071] like Figure 8 As shown, when the first circuit board 21 is a flexible circuit board, the electronic device may further include a reinforcing plate 24, which may be made of steel, iron, or other materials with a certain strength. The reinforcing plate 24 can be used to strengthen the flexible circuit board, making the connection between the first circuit board 21 and the second circuit board 22 more reliable.
[0072] It should be noted that, in specific applications, when both the first circuit board 21 and the second circuit board 22 are printed circuit boards, the first circuit board 21 can be located at... Figure 8The position of the reinforcing plate 24 allows the first circuit board 21 to be positioned relative to the second circuit board 22 at a distance, and to clamp the waterproof ring 23 between them, so that the waterproof ring 23 can achieve waterproofing between the two circuit boards.
[0073] In practical applications, when the functional device is a board-to-board connector, both the male and female ends of the board-to-board connector can be provided with multiple pins, which can be electrically connected to the first circuit board 21 or the second circuit board 22.
[0074] In this embodiment, the diameter of the conductive element 11 of the waterproof ring 23 can be smaller than the spacing between two adjacent pins to avoid short circuits caused by the same conductive element 11 being connected to two adjacent pins simultaneously, thereby improving the safety of the waterproof ring 23. Alternatively, the conductive element 11 can be positioned away from the pins to form a safe distance between the conductive element 11 and the pins, avoiding short circuits in the board-to-board connector.
[0075] In summary, the electronic device may include at least the following advantages:
[0076] In this embodiment, the waterproof ring can be fitted over the functional device. The ring-shaped body of the waterproof ring abuts against the first circuit board and the second circuit board respectively and can deform. Because the ring-shaped body can deform, sealing and waterproofing of the functional device can be achieved through this deformation. Since the waterproof ring includes multiple conductive elements, and adjacent conductive elements are insulated from each other, electromagnetic shielding can be achieved. That is, the waterproof ring can simultaneously provide waterproof protection and electromagnetic shielding, and its installation is simple and occupies little space.
[0077] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
