[0003] In the prior art, connector structures typically include a housing and connection terminals disposed in the housing, and waterproofing is achieved by sealing the housing or by potting the connection terminals.

[0004] However, sealing the outer casing is a complex and costly process. Furthermore, during the potting process for the connecting terminals, adhesive can easily seep into the terminals, causing connection failure. Additionally, the potting process is difficult to implement due to space constraints. Utility Model Content

[0005] In view of the above problems, this utility model is proposed to provide a connector structure and electronic device that overcomes or at least partially solves the above problems.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application propose a connector structure, the connector structure comprising: a first connecting plate, a second connecting plate, and a compressible seal;

[0008] The first connecting plate is provided with a protruding first connecting end, and the second connecting plate is provided with a protruding second connecting end, with the first connecting end and the second connecting end being arranged opposite to each other;

[0009] The sealing element is sleeved on the outer periphery of the first connecting end or the second connecting end;

[0010] The first connecting end is fastened to the second connecting end, and the first connecting plate and the second connecting plate compress the sealing element so that the sealing element seals the first connecting end and the second connecting end.

[0011] Optionally, the connector structure further includes a first adhesive and a second adhesive;

[0012] The first adhesive is attached to the side of the seal near the first connecting plate to bond the seal to the first connecting plate;

[0013] The second adhesive is attached to the side of the seal near the second connecting plate to bond the seal to the second connecting plate.

[0014] Optionally, the sealing element is an annular sealing element, and the inner wall of the annular sealing element is provided with a hollow cavity, with the first connecting end and the second connecting end located in the hollow cavity;

[0015] The first connecting plate and the second connecting plate seal the hollow cavity, forming a sealed space between the first connecting end and the second connecting end.

[0016] Optionally, a gap is provided between the inner wall of the annular seal and the first connecting end or the second connecting end.

[0017] Optionally, the size of the gap is any value between 0.3 and 0.5 mm.

[0018] Optionally, the first connecting plate is a data acquisition flexible board, the second connecting plate is a control board, and the connector structure further includes a reinforcing plate. The reinforcing plate is connected to the side of the data acquisition flexible board away from the seal, and the reinforcing plate is disposed opposite to the first connecting end.

[0019] Optionally, the dimension of the seal along the direction from the first connecting plate to the second connecting plate is a first distance H1, and the distance between the first connecting plate and the second connecting plate is a second distance H2;

[0020] When the first connecting end is not fastened to the second connecting end, the first distance H1 and the second distance H2 satisfy: H2*108%≤H1≤H2*112%.

[0021] Optionally, the seal is made of foam.

[0022] Optionally, the foam is made of either ethylene-vinyl acetate copolymer or chloroprene rubber.

[0023] Secondly, embodiments of this application provide an electronic device that includes the aforementioned connector structure.

[0024] In this embodiment, the connector structure includes: a first connecting plate, a second connecting plate, and a compressible seal. The first connecting plate has a protruding first connecting end, and the second connecting plate has a protruding second connecting end, with the first connecting end and the second connecting end positioned opposite each other. The seal is fitted around the outer periphery of either the first or second connecting end. The first connecting end is fastened to the second connecting end, and the first and second connecting plates compress the seal to seal both the first and second connecting ends. Thus, by fitting the compressible seal around the first or second connecting end, protection is achieved by surrounding the outer periphery of both ends after the first connecting end is fastened to the second connecting end. Furthermore, the compression of the seal by the first and second connecting plates ensures a tight fit between the seal and the first and second connecting plates, forming a relatively effective and reliable seal between the first and second connecting ends.

[0035] Reference Figs. 1 to 3The diagram illustrates a connector structure according to an embodiment of this application. The connector structure may specifically include: a first connecting plate 10, a second connecting plate 20, and a compressible sealing element 30. The first connecting plate 10 has a protruding first connecting end 11, and the second connecting plate 20 has a protruding second connecting end 21, with the first connecting end 11 and the second connecting end 21 positioned opposite each other. The sealing element 30 is sleeved around the outer periphery of the first connecting end 11 or the second connecting end 21. The first connecting end 11 is fastened to the second connecting end 21, and the first connecting plate 10 and the second connecting plate 20 compress the sealing element 30 to seal the first connecting end 11 and the second connecting end 21.

[0036] In this embodiment, a compressible seal 30 is fitted onto the first connecting end 11 or the second connecting end 21. When the first connecting end 11 is fastened to the second connecting end 21, it surrounds the outer periphery of both ends, providing protection. Furthermore, the first connecting plate 10 and the second connecting plate 20 compress the seal 30, ensuring a tight fit between them. This forms a relatively effective and reliable seal between the first connecting end 11 and the second connecting end 21, achieving good waterproofing and reducing the risk of water seepage leading to failure and short circuits. The structure is simple and the process is convenient. It eliminates the need for sealing the outer shell, which would increase manufacturing difficulty and cost. It also eliminates the need for potting the connecting terminals, preventing glue from easily seeping into the first connecting end 11 or the second connecting end 21 and causing connection failure. It also avoids the difficulty of implementing a difficult potting process due to space limitations.

[0037] In this embodiment of the application, the first connecting plate 10 and the second connecting plate 20 of the connector structure are connected by the snap-fit ​​of the first connecting end 11 and the second connecting end 21. This is also called a board-to-board connector structure, or BTB for short. It is widely used in various electronic products, such as mobile phones, computers, tablets, digital cameras, audio equipment and communication equipment.

[0038] Optionally, in this embodiment, the connector structure further includes a first adhesive member 40 and a second adhesive member 50; the first adhesive member 40 is connected to the side of the seal 30 near the first connecting plate 10 to bond the seal 30 to the first connecting plate 10; the second adhesive member 50 is connected to the side of the seal 30 near the second connecting plate 20 to bond the seal 30 to the second connecting plate 20. Thus, the first adhesive member 40 and the second adhesive member 50 further enhance the reliability and stability of the connection between the seal 30 and the first connecting plate 10 and the second connecting plate 20, reducing the risk of loosening or detachment between the seal 30 and the first connecting plate 10 or the second connecting plate 20. This results in better reliability of the connector structure in scenarios involving frequent vibration or shaking during transportation. Furthermore, the structure is simple, the manufacturing process is easy, and it is beneficial for improving assembly efficiency.

[0039] For example, in the embodiments of this application, the first adhesive 40 and the second adhesive 50 can be double-sided adhesive, which is simple, reliable, widely applicable, and easy to implement. Furthermore, the first adhesive 40 and the second adhesive 50 can also be hot melt adhesive, acrylic tape, structural adhesive, etc. The specific types of the first adhesive 40 and the second adhesive 50 are not limited in the embodiments of this application.

[0040] Optionally, in this embodiment, the sealing element 30 is an annular sealing element, the inner wall of which is provided with a hollow cavity 31, and the first connecting end 11 and the second connecting end 21 are located inside the hollow cavity 31; the first connecting plate 10 and the second connecting plate 20 seal the hollow cavity 31, forming a sealed space for the first connecting end 11 and the second connecting end 21. Thus, the hollow cavity 31 of the annular sealing element provides space for the first connecting end 11 and the second connecting end 21, and the first connecting plate 10 and the second connecting plate 20 seal the hollow cavity 31, so that the sealing element 30 and the first connecting plate 10 and the second connecting plate 20 together form a sealed space for the first connecting end 11 and the second connecting end 21, resulting in a better sealing and waterproofing effect.

[0041] For example, in the embodiments of this application, the thickness of the annular seal can be 1.7mm, 1.8mm, 2mm, 2.1mm or 2.3mm, etc., and can be set according to actual needs. The specific value of the thickness of the annular seal is not limited in the embodiments of this application.

[0042] Optionally, in this embodiment, a gap is provided between the inner wall of the annular seal and the first connecting end 11 or the second connecting end 21. This gap provides sufficient assembly space between the seal 30 and the first connecting end 11 or the second connecting end 21, preventing interference between the seal 30 and the first connecting end 11 when it is fastened to the second connecting end 21.

[0043] Optionally, in this embodiment, the size of the gap is any value between 0.3 and 0.5 mm. This ensures that the gap has a suitable size, avoiding insufficient assembly space between the seal 30 and the first connecting end 11 or the second connecting end 21 due to an excessively small gap, and also avoiding the gap being too large to affect the sealing and waterproofing effect of the seal 30 on the first connecting end 11 and the second connecting end 21.

[0044] For example, in the embodiments of this application, the gap can be 0.3mm, 0.4mm or 0.5mm, etc., and can be set according to actual needs. In the embodiments of this application, the specific value of the gap between the inner wall of the annular seal and the first connecting end 11 or the second connecting end 21 is not limited.

[0045] Optionally, in this embodiment, the first connecting plate 10 is a data acquisition flexible board, the second connecting plate 20 is a control board, and the connector structure further includes a reinforcing plate 60. The reinforcing plate 60 is connected to the side of the data acquisition flexible board away from the sealing element 30, and is disposed opposite to the first connecting end 11. In this way, by reinforcing the data acquisition flexible board at the position of the first connecting end 11 using the reinforcing plate 60, the structure is strengthened, resulting in better stability and reliability of the data acquisition flexible board during the fastening process, reducing the risk of deformation or even damage to the data acquisition flexible board during fastening or unfastening.

[0046] Specifically, in this embodiment, the acquisition board can be an FPC (Flexible Printed Circuit) for signal acquisition. Using an FPC allows the acquisition board to be bent according to assembly requirements, facilitating spatial layout. The control board is used to output control signals, specifically a BMS (Battery Management System Control Board), which can perform battery status monitoring, battery protection, equalization management, communication and data transmission, and charging management, etc., for electronic devices.

[0047] Optionally, in this embodiment, the dimension of the sealing member 30 along the direction from the first connecting plate 10 to the second connecting plate 20 is a first distance H1, and the distance between the first connecting plate 10 and the second connecting plate 20 is a second distance H2. When the first connecting end 11 is not fastened to the second connecting end 21, the first distance H1 and the second distance H2 satisfy: H2*108%≤H1≤H2*112%. That is, when the first connecting end 11 is not fastened to the second connecting end 21, the first distance H1 of the sealing member 30, i.e., its height, is 8%-12% larger than the second distance H2 between the first connecting plate 10 and the second connecting plate 20. This allows the sealing member 30 to be compressed after being assembled between the first connecting plate 10 and the second connecting plate 20, forming an interference fit and improving the tightness of the fit between the sealing member 30 and the first connecting plate 10 and the second connecting plate 20.

[0048] Furthermore, setting H2*108%≤H1≤H2*112% avoids the first distance H1 of the seal 30 being too large, making it difficult to compress the seal 30 between the first connecting plate 10 and the second connecting plate 20, and also avoids the first distance H1 of the seal 30 being too small, making it difficult to form a good sealing effect on the first connecting end 11 and the second connecting end 21, thus avoiding affecting its waterproof effect.

[0049] In this embodiment, the sealing element 30 may optionally be foam. Using foam allows the sealing element 30 to have better sealing and waterproof reliability, enabling the connector structure to have a higher waterproof rating. Furthermore, foam is elastic and deformable, compressible, and provides good support stability. In addition, foam is easy to cut and shape, adaptable to different specifications and shapes of the first connecting end 11 and the second connecting end 21, and is lightweight yet strong, contributing to product weight reduction.

[0050] Optionally, in this embodiment, the foam is made of either ethylene-vinyl acetate copolymer (EVA) or chloroprene rubber (CR). EVA offers good flexibility and elasticity, as well as good abrasion resistance and chemical corrosion resistance, is easy to process, and is relatively environmentally friendly. Chloroprene rubber offers good elasticity, mechanical properties, fatigue resistance, and chemical corrosion resistance, among other benefits. Using either ethylene-vinyl acetate copolymer or chloroprene rubber enables the foam to possess good structural stability, elasticity, and structural strength.

[0051] In summary, the connector structure described in the embodiments of this application may include at least the following advantages:

[0052] In this embodiment, the connector structure includes: a first connecting plate, a second connecting plate, and a compressible seal. The first connecting plate has a protruding first connecting end, and the second connecting plate has a protruding second connecting end, with the first connecting end and the second connecting end positioned opposite each other. The seal is fitted around the outer periphery of either the first or second connecting end. The first connecting end is fastened to the second connecting end, and the first and second connecting plates compress the seal to seal both the first and second connecting ends. Thus, by fitting the compressible seal around the first or second connecting end, protection is achieved by surrounding the outer periphery of both ends after the first connecting end is fastened to the second connecting end. Furthermore, the compression of the seal by the first and second connecting plates ensures a tight fit between the seal and the first and second connecting plates, forming a relatively effective and reliable seal between the first and second connecting ends. This results in a better waterproof effect, reducing the risk of failure and short circuits caused by water seepage between the first and second connecting ends. The structure is simple, and the manufacturing process is convenient. The elimination of the need to seal the outer casing leads to greater process difficulty and higher cost. It also eliminates the need to pot the connection terminals, which could easily cause glue to enter the first or second connection terminal and cause connection failure. Furthermore, it avoids the difficulty of potting processes due to space limitations.

The seal is fitted around the outer periphery of either the first or second connecting end. The first connecting end engages with the second connecting end, and the first and second connecting plates compress the seal to seal both the first and second connecting ends. Thus, by fitting the compressible seal around the first or second connecting end, protection is achieved by surrounding the outer periphery of both ends when the first connecting end engages with the second connecting end. Furthermore, the compression of the seal by the first and second connecting plates ensures a tight fit, forming a relatively effective and reliable seal between the first and second connecting ends, resulting in good waterproofing and reducing the risk of failure and short circuits due to water seepage. The structure is simple and the manufacturing process is straightforward. The elimination of the need to seal the outer casing leads to greater process difficulty and higher cost.
