Description

Technical Field

[0001] This application relates to the technical field of connectors, and more particularly to a waterproof connector and a cabinet including the same. Background Technology

[0002] In fields such as industrial control, communication transmission, and outdoor power equipment, server racks serve as the carriers and protectors of core equipment. The stable operation of their internal electronic components highly depends on the reliability of the connections between the rack and external cables. As key components enabling signal / power transmission between the internal circuitry and external cables, the sealing performance of rack connectors directly determines the overall protection level of the rack. Especially in outdoor or humid environments (such as rainy days, high-humidity workshops, and open-air base stations), waterproofing and moisture resistance become crucial requirements for ensuring the normal operation of connector pins, sockets, and other core conductive components.

[0003] Currently, the sealing structure of the connector-chassis contact surface often suffers from uneven compression of the sealing ring due to installation tolerances and long-term vibration, or loss of elasticity due to material aging, allowing water vapor to easily seep in along the gaps in the contact surface. Simultaneously, at the cable and connector penetration holes, micro-gaps can easily form due to cable outer diameter tolerances or improper interference fit design between the sealing structure and the cable, allowing water vapor to slowly intrude into the cabinet. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproof connector and a cabinet including the connector, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On the one hand, a waterproof connector is provided for use in server racks, comprising:

[0007] A first connecting block has multiple connecting holes for connecting cables, and a first sealing unit for sealing the first port and the cable is provided at the first port of each connecting hole; and

[0008] The second connecting block is used to connect the first connecting block and the cabinet. A second sealing unit for sealing the cabinet panel and the first connecting surface is provided on the first connecting surface of the second connecting block.

[0009] The first sealing unit includes:

[0010] The connecting ring fitted on the outer diameter of the cable, and

[0011] A sealing ring is disposed between the connecting ring and the outer diameter of the cable.

[0012] When the connecting ring is fitted onto the cable, the sealing ring is squeezed together between the connecting ring and the outer diameter of the cable.

[0013] The second sealing unit includes:

[0014] The sealing strip is arranged in a ring shape. When the second connecting block is connected to the cabinet, the sealing strip is connected between the second connecting block and the cabinet in a squeezed shape, and the connecting terminal on the first connecting surface of the second connecting block is located within the ring area of ​​the sealing strip.

[0015] Preferably, the second connecting block has a through hole corresponding to the connecting hole on the first connecting block, and the through hole extends through the connecting terminal.

[0016] Preferably, the second connecting block further includes a connecting plate and a first connecting portion for connecting the first connecting block.

[0017] A connecting cavity is provided on the first connecting part, and the first connecting block is detachably snapped into the connecting cavity.

[0018] Preferably, it further includes a snap-fit ​​structure for connecting the first connecting block and the second connecting block, which includes:

[0019] At least one snap-fit ​​block disposed on the inner wall of the connecting cavity, and a snap-fit ​​groove formed on the second connecting block to allow interlocking with the snap-fit ​​block; and / or,

[0020] At least one snap-fit ​​groove is formed in the inner wall of the connecting cavity, and a snap-fit ​​block is disposed on the second connecting block that allows snap-fit ​​with the snap-fit ​​groove.

[0021] Preferably, the connecting ring includes two semi-circular first ring bodies and second ring bodies. The first ring bodies and the second ring bodies are connected to each other to form a complete annular connecting surface, and the annular connecting surface includes at least one connecting groove for setting the sealing ring.

[0022] Preferably, the connecting ring is fixedly connected to a connecting arc plate, and the outer surface of the connecting arc plate is used to connect to the inner wall of the connecting hole.

[0023] Preferably, a plurality of arc-shaped protrusions are provided on the outer surface of the connecting arc piece, and the height of the protrusions decreases sequentially along the first direction from the connecting ring to the end of the connecting arc piece;

[0024] Rigid reinforcing ribs are wrapped inside the raised strip.

[0025] Preferably, a first groove is formed on the first connecting surface, and the sealing strip is fixedly connected to the first groove, and the sealing strip protrudes from the first connecting surface.

[0026] Preferably, it also includes a sealing sleeve, which is fitted onto the cable, and after the sealing sleeve covers the entire first connecting portion, its edge is fixedly connected to the connecting plate.

[0027] On the other hand, this disclosure also provides a cabinet that includes the waterproof connector as described in any of the above.

[0028] The beneficial effects of this application are as follows:

[0029] 1. The gap between the cable and the first connecting block is sealed by the connecting ring, sealing ring and connecting arc plate of the first sealing unit, and the interface between the second connecting block and the cabinet is sealed by the annular sealing strip of the second sealing unit, thus blocking the path of water vapor to seep in along the gaps or interfaces of the contact surface from the source.

[0030] 2. The raised strips of the connecting arc plate can adaptively fill the gaps in the connecting holes, forming a "radial + axial" double seal when fitted with the axial end face. Furthermore, the sealing sleeve fully encloses the first connecting part, sealing any potential gaps in the snap-fit ​​structure, creating a combined effect of basic sealing and secondary protection.

[0031] 3. The annular sealing strip wraps the connection terminals and other core electrical components within the annular sealing area, preventing moisture from directly corroding key conductive parts and significantly reducing the risk of equipment failures such as short circuits and corrosion.

[0032] 4. The anti-pull-out locking part between the first and second rings, and the locking structure between the first and second connecting blocks, effectively prevent the connection from separating due to vibration or external force, ensuring the long-term stability of the sealing structure. Additionally, the raised strip has built-in rigid reinforcing ribs, ensuring elastic sealing capability while preventing excessive deformation or aging failure. Attached Figure Description

[0046] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] Please see Figures 1 to 7 This disclosure provides a server rack with a waterproof connector mounted on its cabinet. The waterproof connector's inherent waterproof capability effectively improves the waterproof performance at the connection point between the connector and the rack. This enhances both the sealing performance of the cable 10 and the waterproof connector at their connection points. By improving the sealing at both connection points, water vapor is prevented from seeping into the rack through gaps in the contact surfaces and from entering the rack through the interface between the cable 10 and the waterproof connector.

[0050] Furthermore, the cabinets provided in this disclosure can be server cabinets, network cabinets, industrial control cabinets, power cabinets, or outdoor cabinets, but are not limited to these. Cabinets that can be electrically connected via connectors can all use the waterproof connectors provided in this disclosure.

[0051] Please see Figures 1 to 7 In one embodiment, the waterproof connector provided in this disclosure includes a first connecting block 100, a second connecting block 200, a first sealing unit 110, and a second sealing unit 210. A cable 10 is connected to the first connecting block 100, the first connecting block 100 is connected to the second connecting block 200, and the second connecting block 200 is connected to a server rack. The first sealing unit 110 is disposed at the connection point between the cable 10 and the first connecting block 100, and the second sealing unit 210 is connected at the connection point between the second connecting block 200 and the server rack. The first sealing unit 110 and the second sealing unit 210 seal the two connection points respectively, thereby improving the sealing performance of the waterproof connector and preventing moisture from entering the server rack through the connection points.

[0052] Understandably, by sealing the gap between the cable 10 and the connection hole 101 of the first connecting block 100 with the first sealing unit 110, and sealing the connection between the second connecting block 200 and the cabinet with the second sealing unit 210, the sealing effect at the two critical connection points—the cable 10 and the waterproof connector, and the waterproof connector and the cabinet—is specifically strengthened. This prevents water vapor from seeping into the cabinet through gaps or interfaces on the contact surface, significantly reducing the risk of equipment malfunctions such as short circuits and corrosion caused by moisture.

[0053] Specifically, the first connecting block 100 has multiple connecting holes 101 for connecting cables 10, and the ends of the cables 10 are disposed within the connecting holes 101. Each connecting hole 101 includes a first port and a second port. The cable 10 enters the connecting hole 101 through the first port, and a first sealing unit 110 is disposed at the first port. Therefore, the first sealing unit 110 can seal the gap between the cable 10 and the connecting hole 101 at the first port, thereby improving the sealing performance.

[0054] Furthermore, the first connecting block 100 has a rectangular block structure, and four sets of connecting holes 101 are linearly arranged on the first connecting block 100, with the connecting holes 101 penetrating through the first connecting block 100. However, it is not limited to this; the specific structural form of the first connecting block 100 can be determined according to actual needs. For example, the cross-section of the first connecting block 100 can be circular, and the first connecting holes 101 can be evenly arranged on the first connecting block 100.

[0055] Understandably, the structural form of the first connecting block 100, such as a rectangular or circular cross-section, and the arrangement of the connecting holes 101, such as linear or uniform arrangement, can be adjusted according to actual needs. This not only meets the functional requirements of connecting multiple cables 10, but also adapts to different numbers and arrangements of cables 10, enhancing the adaptability of the solution in diverse application scenarios.

[0056] Please see Figures 1 to 7 In one embodiment, the first sealing unit 110 includes a connecting ring 111 sleeved on the outer diameter of the cable 10, and a sealing ring 112 disposed between the outer diameter of the cable 10 and the connecting ring 111. When the connecting ring 111 is sleeved on the cable 10, the sealing ring 112 is squeezed and connected between the connecting ring 111 and the outer diameter of the cable 10.

[0057] Specifically, to facilitate the placement of the connecting ring 111 and the sealing ring 112 on the outer diameter of the cable 10 end, the connecting ring 111 can be configured as a split structure. That is, the connecting ring 111 can include a first ring body 1110 and a second ring body 1111. After the first ring body 1110 and the second ring body 1111 are connected to each other, a complete connection surface can be constructed. Simultaneously, at least one connecting groove 1112 for setting the sealing ring 112 is included on the connection surface. The specific number of connecting grooves 1112 can be determined according to actual sealing requirements. For example, for applications requiring high sealing performance, three connecting grooves 1112 can be provided. For applications requiring general sealing performance, one connecting groove 1112 can be provided. It is understood that the sealing ring 112, through a compression connection between the connecting ring 111 and the outer diameter of the cable 10, forms a tightly fitting sealing structure, effectively blocking the path of moisture seepage along the gap between the cable 10 and the connecting block. Meanwhile, the number of connecting grooves 1112 can be flexibly adjusted according to sealing requirements, such as 3 for high-sealing scenarios and 1 for general scenarios, to achieve precise adaptation of sealing levels and meet waterproof requirements in diverse environments.

[0058] Furthermore, the first ring 1110 and the second ring 1111 are detachably snap-fitted together. In actual use, the sealing ring 112 can be first fitted onto the outer diameter of the cable 10; then the first ring 1110 and the second ring 1111 are snapped together at the position of the sealing ring 112, so that the sealing ring 112 is locked and connected inside the connecting ring 111. It can be understood that by setting the sealing ring 112, different sizes of sealing rings 112 can be selected according to the actual diameter of the cable 10. By adopting a separate structure of the first ring 1110 and the second ring 1111 for the connecting ring 111, combined with the detachable snap-fit ​​fixing method, the sealing ring 112 can be first fitted onto the cable 10, and then the assembly can be completed by snap-fitting the rings. This avoids the limitations of the traditional integrated structure on the pre-installation of the cable 10, greatly reduces the installation difficulty in scenarios where the cable 10 has already been laid, and simplifies the construction process.

[0059] For cabinet-type air conditioners, the diameter of the holes used to connect waterproof connectors is usually consistent. However, different requirements necessitate different diameter cables 10. Therefore, by using identical connecting rings 111 and sealing rings 112 of different diameters, cables 10 of different diameters can be fitted to the connecting holes 101 on the first connecting block 100. By replacing the sealing rings 112 with different sizes, cables 10 of different diameters can be fitted, while the structure of the connecting rings 111 remains uniform, without requiring changes to the design of the cabinet connecting holes 101 or the first connecting block 100. This effectively resolves the contradiction between the cabinet's fixing hole diameter and the diverse diameters of cables 10, enabling the same connecting block and cabinet to be compatible with multiple cable 10 specifications, thus improving the versatility and reusability of the solution.

[0060] Furthermore, a first snap-fit ​​component may be provided at the connection between the first ring body 1110 and the second ring body 1111. For example, hook portions are fixedly connected to the first ring body 1110 and the second ring body 1111 respectively, and the hook portions on the first ring body 1110 and the second ring body 1111 can fit together. Anti-pull-out snap-fit ​​portions or snap-fit ​​holes for connecting snap-fit ​​portions are provided on the hook portions of the first ring body 1110 or the second ring body 1111 respectively. When the first ring body 1110 and the second ring body 1111 are connected, the first ring body 1110 and the second ring body 1111 are connected to each other by connecting the snap-fit ​​portions and the snap-fit ​​holes. By providing anti-pull-out snap-fit ​​portions, separation between the first ring body 1110 and the second ring body 1111 can be effectively prevented. Understandably, the first ring 1110 and the second ring 1111 are connected by a snap-fit ​​part with anti-pull-out function, which can effectively prevent the rings from separating due to vibration, external force and other factors during long-term use, ensuring that the sealing ring 112 is always in a stable compression sealing state, and guaranteeing the long-term reliability of the sealing structure.

[0061] Please see Figures 1 to 7 In one embodiment, to improve the sealing performance of the first sealing unit 110 between the cable 10 and the first connecting block 100, a connecting arc plate 113 may be fixedly connected to the connecting ring 111, the connecting arc plate 113 being inserted into the connecting hole 101.

[0062] Specifically, connecting arc pieces 113 are respectively disposed on the first ring body 1110 and the second ring body 1111. The connecting arc pieces 113 on the first ring body 1110 and the second ring body 1111 can be spliced ​​into a covering structure covering the cable 10, and the outer surface of the connecting arc pieces 113 is connected to the inner wall of the connecting hole 101. Therefore, when the connecting ring 111 is connected to the first port of the connecting hole 101, its connecting arc pieces 113 are inserted into the connecting hole 101, and the side of the connecting ring 111 near the first port is attached to the cross-section of the first connecting block 100. It can be understood that the connecting arc pieces 113 are respectively disposed on the first ring body 1110 and the second ring body 1111, and after splicing, they form a structure covering the cable 10, and the outer surface is attached to the inner wall of the connecting hole 101. By increasing the contact area between the connecting ring 111 and the connecting hole 101, the connection stability between the first sealing unit 110 and the first connecting block 100 is improved, preventing the connecting ring 111 from loosening or shifting during use; at the same time, the encapsulated structure initially fills the gap between the connecting ring 111 and the connecting hole 101, providing basic support for subsequent sealing.

[0063] Simultaneously, the connecting arc plate 113 is inserted into the connecting hole 101, and cooperates with the connecting ring 111 to adhere to the cross-section of the first connecting block 100, forming a dual structure of radial protrusion strip 1130 sealing and axial end face fitting sealing. This can further enhance the waterproof performance at the connection between the cable 10 and the first connecting block 100, blocking the water vapor infiltration path from multiple dimensions in the radial and axial directions, and greatly improving the sealing reliability.

[0064] Furthermore, several arc-shaped raised strips 1130 are provided on the outer surface of the connecting arc plate 113, and the height of the raised strips 1130 decreases sequentially along the first direction from the connecting ring 111 to the end of the connecting arc plate 113. The connecting guard plate is made of a rigid material, while the raised strips 1130 are made of a deformable material. For example, the raised strips 1130 are made of rubber. When the connecting ring 111 is connected to the connecting hole 101, the connecting arc plate can compress the raised strips 1130 to deform, thereby sealing the gap between the connecting arc plate and the inner wall of the connecting hole 101. It is understood that the arc-shaped raised strips 1130 on the outer surface of the connecting arc plate 113 are made of a deformable material, and their height decreases sequentially along the insertion direction. When the connecting arc plate 113 is inserted into the connecting hole 101, the raised strip 1130 is compressed and deformed, which can adaptively fill the irregular gap between the connecting arc plate 113 and the inner wall of the connecting hole 101, forming a tight elastic seal and effectively blocking the path of water vapor seeping in along the gap. The height-decreasing design reduces the insertion resistance, facilitates installation, and ensures that the raised strip 1130 gradually fits tightly from the end to the root during the insertion process, improving the overall seal.

[0065] It is important to note that a rigid reinforcing rib 1131 is encased within the raised strip 1130. Understandably, the rigid reinforcing rib 1131 within the raised strip 1130 limits excessive deformation or fatigue damage caused by long-term compression, maintaining its structural strength while ensuring the elastic sealing capability of the raised strip 1130. The inclusion of the reinforcing rib 1131 effectively avoids the problem of easy aging and failure of purely deformable materials, ensuring that the sealing structure maintains a stable sealing effect even under long-term use or vibration environments, thus extending the service life of the sealing unit.

[0066] Please see Figures 1 to 7In one embodiment, the second connecting block 200 is used to connect the first connecting block 100 and the cabinet. A second sealing unit 210 for sealing the cabinet panel and the first connecting surface 201 is provided on the first connecting surface 201 of the second connecting block 200. The second sealing unit 210 includes a ring-shaped sealing strip 211. When the second connecting block 200 is connected to the cabinet, the sealing strip 211 is compressed and connected between the second connecting block 200 and the cabinet. The connecting terminal 203 on the second connecting block 200 located on the first connecting surface 201 is located within the ring-shaped area of ​​the sealing strip 211. Through the elastic deformation of the sealing strip 211, a complete ring seal is formed between the second connecting block 200 and the cabinet panel, enclosing key electrical components such as the connecting terminal 203 within the sealed area. This prevents moisture, dust, and other impurities from entering the core electrical connection area, effectively protecting the insulation and conductivity of the connecting terminal 203 and reducing the risk of short circuits or poor contact.

[0067] Furthermore, the second connecting block 200 has a through hole 202 corresponding to the connecting hole 101 on the first connecting block 100, and the through hole 202 passes through the connecting terminal 203. The second port of the connecting hole 101 on the first connecting block 100 is connected to the through hole 202. It can be understood that the through holes 202 on the second connecting block 200 correspond one-to-one with the connecting holes 101 on the first connecting block 100, and the through holes 202 pass through the connecting terminal 203, with the second port of the connecting hole 101 on the first connecting block 100 precisely aligned with the through hole 202. This effectively ensures the continuity of the cable 10 from the first connecting block 100 to the second connecting block 200, avoiding poor contact caused by misalignment. Simultaneously, the corresponding through-hole structure reduces connection gaps, and combined with the sealing design, further enhances the overall waterproof performance, ensuring the stability of electrical signal or power transmission.

[0068] The second connecting block 200 further includes a connecting plate 204 and a first connecting part 205 for connecting the first connecting block 100. A connecting cavity 2050 is provided on the first connecting part 205, and the first connecting block 100 is detachably snapped into the connecting cavity 2050.

[0069] Specifically, a snap-fit ​​structure 206 may be provided between the inner wall of the connecting cavity 2050 and the first connecting block 100 for connecting the first connecting block 100 and the second connecting block 200. Further, the snap-fit ​​structure 206 includes at least one snap-fit ​​block 2061 disposed on the inner wall of the connecting cavity 2050, and a snap-fit ​​groove 2062 formed on the second connecting block 200 that allows snap-fit ​​with the snap-fit ​​block 2061; and / or, at least one snap-fit ​​groove 2062 formed on the inner wall of the connecting cavity 2050, and a snap-fit ​​block 2061 disposed on the second connecting block 200 that allows snap-fit ​​with the snap-fit ​​groove 2062. The first connecting block 100 is detachably fixed via the snap-fit ​​structure 206 through the connecting cavity 2050 of the second connecting block 200. On the one hand, the snap-fit ​​method allows for disassembly and assembly without additional tools, significantly improving the efficiency of cabinet cabling and equipment maintenance; on the other hand, the mechanical locking function of the snap-fit ​​structure 206 ensures that the first connecting block 100 and the second connecting block 200 are not easily separated under vibration or external force, thus ensuring the structural stability of the connection and the reliability of the electrical connection.

[0070] Furthermore, a first groove 212 is provided on the first connecting surface 201, and a sealing strip 211 is fixedly connected within the first groove 212, with the sealing strip 211 protruding from the first connecting surface 201 by a first distance. Specifically, the first groove 212 on the first connecting surface 201 is used to fix the sealing strip 211, preventing the sealing strip 211 from shifting or falling off during installation or long-term use, ensuring the accuracy of the sealing position. The "first distance" by which the sealing strip 211 protrudes from the first connecting surface 201 ensures that when the second connecting block 200 is connected to the cabinet, the sealing strip 211 can be fully compressed and deformed to fill the tiny gaps in the contact surface, maximizing the sealing effect and preventing moisture infiltration due to insufficient sealing.

[0071] Please see Figures 1 to 7In one embodiment, a sealing sleeve 300 may also be fitted onto the cable 10. When the sealing sleeve 300 covers the entire first connecting portion 205, its edge is fixedly connected to the connecting plate 204. It is understood that the sealing sleeve 300 covers the entire connection area between the first connecting block 100 and the second connecting block 200, forming a physical barrier for this core connection part, sealing any small gaps that may exist in the snap-fit ​​structure 206 between the first connecting block 100 and the second connecting block 200, and effectively preventing moisture, dust, and other impurities from seeping into the first connecting portion 205. This adds a layer of full-coverage protection to the original snap-fit ​​seal, forming a dual sealing system of the snap-fit ​​structure 206 and the sealing sleeve 300, significantly improving the overall sealing performance of the first connecting portion 205. Meanwhile, the sealing sleeve 300 works in concert with the first sealing unit 110 and the second sealing unit 210 to construct a three-dimensional multi-layer waterproof protection system from the end of the cable 10, the first connecting block 100, the second connecting block 200, the first connecting part 205 to the cabinet interface.

[0072] In summary, this disclosure provides a waterproof connector and a cabinet including the connector. The first sealing unit 110 achieves gap sealing between the cable 10 and the first connecting block 100 through the connecting ring 111, sealing ring 112, and connecting arc plate 113. The second sealing unit 210's annular sealing strip 211 achieves interface sealing between the second connecting block 200 and the cabinet, blocking moisture from seeping in along the contact surface gaps or interface. Simultaneously, the raised strip 1130 of the connecting arc plate 113 can adaptively fill the gap of the connecting hole 101, forming a "radial + axial" double seal in conjunction with the axial end face. Furthermore, the sealing sleeve 300 fully encloses the first connecting part 205, and the closed snap-fit ​​structure 206 seals potential gaps, creating a combined effect of basic sealing and secondary protection. The annular sealing strip 211 encloses the connecting terminal 203 and other core electrical components within the annular sealing area, preventing moisture from directly corroding critical conductive parts and significantly reducing the risk of equipment short circuits, corrosion, and other malfunctions. The anti-pull-out latching parts of the first ring 1110 and the second ring 1111, and the latching structure 206 of the first connecting block 100 and the second connecting block 200, effectively prevent connection separation caused by vibration or external force, ensuring the long-term stability of the sealing structure. The raised strip 1130 has built-in rigid reinforcing ribs 1131, ensuring elastic sealing capability while preventing excessive deformation or aging failure. Therefore, it can effectively meet the waterproof performance requirements of various cabinet scenarios.
