Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with waterproof function. Background Technology

[0002] Connectors are indispensable components in electronic devices, used to achieve electrical connections and signal transmission. They are widely used in various industries and fields, such as electronic equipment, automobile manufacturing, industrial control, outdoor lighting, and aerospace. In these applications, connectors need to have good electrical performance, mechanical performance, and reliability to ensure the normal operation of the equipment.

[0003] Connectors are one of the most important components of communication equipment. They connect communication lines and facilitate the use of communication equipment. However, water may be spilled on the communication equipment during use and come into contact with the connector, causing the communication equipment to malfunction. Therefore, a waterproof connector is needed.

[0004] An existing patent (publication number: CN220233570U) discloses a waterproof connector. By incorporating a dustproof component and a waterproof sleeve, the connector is designed to prevent dust accumulation. When the connector is in use, the mounting shell is fixedly installed on one side of the outer wall of the mounting shell, and then a protective plate and a connecting plate are fixedly connected. One end of the connecting plate is fixedly connected to one side of the outer wall of the mounting shell, thus providing dust protection. When the connector is connected to a circuit, the protective plate is pushed open by the circuit. When the circuit is separated from the connector, the protective plate returns to its original position via a connecting spring on one side of the outer wall, fixing the waterproof sleeve to one side of the inner wall of the mounting shell. This design prevents water from entering the connector when it is connected to the circuit. When not in use, the connector is protected against dust and water by the protective plate, and it is also waterproofed by the waterproof sleeve during use.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing waterproof connectors typically lack quick-disassembly structures, making maintenance difficult. This results in a significant amount of time being spent disassembling screws or seals when internal components need to be inspected, impacting equipment maintenance efficiency. Furthermore, existing waterproof connectors usually rely solely on the waterproof housing to passively block moisture, making it difficult to actively address internal moisture accumulation. Consequently, when ambient humidity changes or condensation occurs, a humid environment can easily form inside the housing, affecting the performance of electrical components.

[0006] Therefore, a waterproof connector is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a waterproof connector that solves the problem that existing waterproof connectors usually lack quick-disassembly and assembly structures, making maintenance inconvenient. As a result, when internal components need to be repaired, a lot of time needs to be spent disassembling screws or seals, which affects the efficiency of equipment maintenance. Moreover, existing waterproof connectors usually only rely on the waterproof shell to passively block water, which is not conducive to actively dealing with the accumulation of internal moisture. Therefore, when the ambient humidity changes or condensation occurs, a humid environment is easily formed inside the shell, which affects the performance of electrical components.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a waterproof connector, comprising a waterproof housing, a connector head disposed inside the waterproof housing, a quick-release sealing assembly disposed on the top of the waterproof housing, and an auxiliary ventilation assembly disposed on the bottom of the waterproof housing;

[0009] The quick-release sealing assembly includes a rotating seat fixedly connected to the top of the waterproof housing. A waterproof sealing plate is rotatably connected to the top of the rotating seat. A fixed seat is fixedly connected to the left side of the waterproof housing. A connecting seat is rotatably connected to the top of the fixed seat. A support is fixedly connected to the bottom of the connecting seat. A fixed support rod is slidably connected to the top of the support rod. The fixed support rod is engaged with the fixed seat. A reset plate is fixedly connected to the outside of the fixed support rod. A reset spring is fixedly connected to the top of the reset plate. The reset spring is located inside the support.

[0010] Preferably, the auxiliary ventilation component includes a support base fixedly connected to the bottom of the waterproof housing, a humidity sensor is provided on the outside of the support base, and a placement box is slidably connected inside the support base.

[0011] Preferably, a pull rod is fixedly connected to the outside of the placement box, a ventilation plate is fixedly connected to the bottom of the placement box, and a ventilation shell is fixedly connected to the bottom of the support base.

[0012] Preferably, a fan body is provided inside the ventilation housing, the fan body is located at the bottom of the ventilation plate, and a dustproof plate is fixedly connected to the bottom of the ventilation housing.

[0013] Preferably, the waterproof housing is internally fixedly connected to a limiting support, the limiting support is slidably connected to a limiting connector, and the limiting connector is fixedly connected to the connector head.

[0014] Preferably, an auxiliary gasket is provided on the outer side of the waterproof housing, and a connecting rod is rotatably connected to the inner side of the auxiliary gasket. The connecting rod is threadedly connected to the limiting connector.

[0015] Preferably, a sealing gasket is fixedly connected to the outer side of the left waterproof housing, and a wire is provided inside the sealing gasket, which is electrically connected to the connector.

[0016] Preferably, the right waterproof housing is provided with a cable sleeve, and both sides of the cable sleeve are provided with signal on / off indicator lights.

[0017] Preferably, the waterproof housing has a protective pad inside, and the protective pad is made of rubber.

[0018] Preferably, a sealing sleeve is embedded in the inner side of the waterproof shell, and the sealing sleeve is made of rubber.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This application achieves rapid installation and waterproof sealing through a quick-release sealing component, improving connector assembly and disassembly efficiency and waterproof reliability. Compared to traditional connectors that use screw fixing or a single sealing structure, this component uses a rotating connection between the rotating seat and the waterproof sealing plate, along with a mechanical snap-fit ​​structure of a fixed support rod and a return spring. This allows for the covering and locking of the waterproof sealing plate in a short time, enabling rapid assembly and disassembly. At the same time, the elastic force of the return spring continuously maintains the snap-fit ​​state between the fixed support rod and the fixed seat, ensuring a seal even under vibration. This solves the problems of cumbersome assembly and disassembly, poor sealing durability, and easy loosening due to vibration that can lead to waterproof failure in traditional structures.

[0021] 2. This application achieves active humidity monitoring and dehumidification through an auxiliary ventilation component, improving the working stability and service life of the connector in humid environments. Compared to the traditional connector design that relies solely on a waterproof structure to passively block moisture intrusion, this component monitors the internal humidity of the housing in real time through a humidity sensor. When the humidity exceeds the threshold, the fan body is automatically activated, forming an air circulation system in conjunction with the dustproof plate, ventilation plate, and desiccant placed in the box, thus achieving active dehumidification. This effectively reduces the internal humidity of the housing, preventing problems such as contact corrosion and short circuits caused by moisture or condensation. It solves the shortcomings of traditional waterproof connectors that cannot cope with internal moisture accumulation, improving the connector's environmental adaptability in high humidity environments.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-8 The present invention provides the following technical solution:

[0033] A waterproof connector includes a waterproof housing 1, a connector 2 disposed inside the waterproof housing 1, a quick-release sealing assembly 4 disposed on the top of the waterproof housing 1, and an auxiliary ventilation assembly 5 disposed on the bottom of the waterproof housing 1.

[0034] The quick-release sealing assembly 4 includes a rotating seat 401 fixedly connected to the top of the waterproof housing 1. A waterproof sealing plate 402 is rotatably connected to the top of the rotating seat 401. A fixed seat 403 is fixedly connected to the left side of the waterproof housing 1. A connecting seat 404 is rotatably connected to the top of the fixed seat 403. A support 405 is fixedly connected to the bottom of the connecting seat 404. A fixed support rod 406 is slidably connected to the top of the support 405. The fixed support rod 406 is engaged with the fixed seat 403. A reset plate 407 is fixedly connected to the outside of the fixed support rod 406. A reset spring 408 is fixedly connected to the top of the reset plate 407. The reset spring 408 is located inside the support 405.

[0035] In this embodiment: by flipping the waterproof sealing plate 402 upwards, it covers the top opening of the waterproof housing 1 with the rotating seat 401 as the fulcrum. At this time, the connecting seat 404 at the top of the fixed seat 403 drives the support seat 405 to rotate, so that the fixed support rod 406 in the support seat 405 is aligned with the slot of the fixed seat 403. When the fixed support rod 406 is pulled upwards, the return spring 408 is compressed. When the fixed support rod 406 moves above the slot, the hand is released, and the return spring 408 releases its elastic force to push the fixed support rod 406. The rod is inserted downward into the slot of the fixing base 403. At the same time, the reset plate 407 on the outside of the fixing rod 406 abuts against the top surface of the support base 405 to form a mechanical clamp. The elastic force of the reset spring 408 keeps the fixing rod 406 in the clamped state. It will not loosen on its own even in a vibration environment, thus firmly fixing the waterproof sealing plate 402 to the top of the housing. Together with the sealing sleeve 14 and the protective pad 3, a complete waterproof cavity is formed to achieve a waterproof seal on the top of the connector and prevent rainwater and moisture from entering the internal circuit from the top opening.

[0036] Specifically, such as Figure 3 As shown, the auxiliary ventilation component 5 includes a support base 501 fixedly connected to the bottom of the waterproof housing 1, a humidity sensor 502 is provided on the outside of the support base 501, and a placement box 503 is slidably connected inside the support base 501.

[0037] Specifically, such as Figure 3 As shown, a pull rod 504 is fixedly connected to the outside of the placement box 503, a ventilation plate 505 is fixedly connected to the bottom of the placement box 503, and a ventilation shell 506 is fixedly connected to the bottom of the support base 501.

[0038] Specifically, such as Figure 3 As shown, a fan body 507 is provided inside the ventilation housing 506. The fan body 507 is located at the bottom of the ventilation plate 505, and a dustproof plate 508 is fixedly connected to the bottom of the ventilation housing 506.

[0039] In this embodiment: when the connector is in a humid environment or when condensation occurs inside due to temperature difference, the humidity sensor 502 on the outside of its support base 501 monitors the humidity inside the housing in real time. When the humidity exceeds a preset threshold, the humidity sensor 502 triggers the circuit to start the fan body 507 inside the ventilation housing 506. When the fan is running, the outside air passes through the dustproof plate 508 at the bottom of the ventilation housing 506 to filter dust, and then passes upward through the ventilation plate 505 into the placement box 503. The desiccant in the placement box 503 dehumidifies the air. The dried air then passes through the ventilation plate 505 into the waterproof housing 1, forming an air circulation. The operator can pull the pull rod 504 on the outside of the placement box 503 to pull the placement box 503 out of the support base 501 and replace the failed desiccant. By combining active ventilation and dehumidification, the humidity inside the housing is reduced, preventing corrosion or short circuits of the contacts caused by moisture, thereby improving the environmental adaptability and service life of the connector.

[0040] Specifically, such as Figure 3 As shown, the waterproof housing 1 is internally fixedly connected to a limiting support 6, the limiting support 6 is slidably connected to a limiting connector 7, and the limiting connector 7 is fixedly connected to the connector 2.

[0041] Specifically, such as Figure 3 As shown, an auxiliary gasket 8 is provided on the outer side of the waterproof housing 1, and a connecting rod 9 is rotatably connected to the inner side of the auxiliary gasket 8. The connecting rod 9 is threadedly connected to the limit connector 7.

[0042] In this embodiment: By setting a limiting support 6 and a limiting connector 7, when installing the connector 2, the connector 2 is first fixedly connected to the limiting connector 7. Then, the limiting connector 7 is pushed into the waterproof housing 1 along the guide structure of the limiting support 6. During the sliding process, the track of the limiting support 6 can accurately limit the movement path of the connector 2, ensuring that the connector 2 is positioned at the preset installation position, so as to ensure the accurate alignment of the connector 2 during installation. By setting an auxiliary gasket 8 and a connecting rod 9, after the initial installation of the connector 2 and the limiting connector 7 is completed, the connecting rod 9 is passed through the rotating hole of the auxiliary gasket 8, aligned with the threaded hole of the limiting connector 7, and rotated clockwise. Since the auxiliary gasket 8 is tightly attached to the outside of the waterproof housing 1, the rotation of the connecting rod 9 will generate an axial thrust, which will firmly press the limiting connector 7 onto the limiting support 6 to form a rigid fixation. The auxiliary gasket 8 fills the gap between the connectors through the elastic deformation of the gasket, enhancing the sealing of the outside of the waterproof housing 1, so as to ensure the stability of the connector 2 in long-term operation.

[0043] Specifically, such as Figure 5 As shown, a sealing gasket 10 is fixedly connected to the outer side of the waterproof housing 1 on the left side. A wire 11 is provided inside the sealing gasket 10, and the wire 11 is electrically connected to the connector 2.

[0044] Specifically, such as Figure 6 As shown, the right waterproof housing 1 is provided with a cable sleeve 12, and signal on / off indicator lights 13 are provided on both sides of the cable sleeve 12.

[0045] In this embodiment: by setting a sealing gasket 10 and a wire 11, when it is necessary to organize the ribbon cables, multiple ribbon cables are threaded into the ribbon cable sleeve 12 in parallel. The inner wall of the sleeve can bind and protect the ribbon cables, preventing them from becoming tangled or loosened due to external pulling. After the ribbon cables are connected, the signal on / off indicator light 13 is connected in parallel with the signal transmission line of the connector 2 through an internal circuit. When the connector 2 is conducting normally, the indicator light illuminates green; if the connector 2 has poor contact or is disconnected, the indicator light switches to red. Operators can quickly determine the working status of the connector by observing the indicator light color, and troubleshooting can be performed without disassembling the housing. This design is applicable to industrial control or communication equipment. This is particularly practical, as it can standardize the cable layout to reduce electromagnetic interference and improve equipment maintenance efficiency through visual indicators. By setting up the cable sleeve 12 and the signal on / off indicator 13, the cable sleeve 12 can bind and protect the cable, preventing the cable from being tangled or the interface from loosening due to external pulling. After the cable is connected, the signal on / off indicator 13 is connected in parallel with the signal transmission line of the connector 2 through the internal circuit. When the connector 2 is conducting normally, the indicator light is green. If the connector 2 has poor contact or is disconnected, the indicator light switches to red. Operators can quickly judge the working status of the connector by observing the color of the indicator light and troubleshoot without disassembling the housing.

[0046] Specifically, such as Figure 8 As shown, a protective pad 3 is provided inside the waterproof housing 1, and the protective pad 3 is made of rubber.

[0047] Specifically, such as Figure 4 As shown, a sealing sleeve 14 is embedded inside the waterproof housing 1, and the sealing sleeve 14 is made of rubber.

[0048] In this embodiment: By setting a protective pad 3, when installing the connector 2, the protective pad 3 is first fixed in the groove of the inner wall of the waterproof housing 1. Then the connector 2 slides in along the limiting support 6. The protective pad 3 will undergo elastic deformation due to the compression of the connector 2, filling the gap between the connector 2 and the housing. The rubber protective pad 3 has good sealing and buffering performance. On the one hand, it can prevent water from penetrating into the gaps inside the housing, thus helping to enhance the overall waterproof effect. On the other hand, when the connector is subjected to vibration or impact, the protective pad 3 can absorb external force and avoid structural damage caused by direct collision between the connector 2 and the housing. By setting a sealing sleeve 14, which is pre-embedded in the annular groove of the waterproof housing 1 during installation, when the connector 2 slides into the interior of the waterproof housing 1 along the limiting support 6, the two waterproof housings 1 are aligned and fixed. The elastic material of the sealing sleeve 14 generates radial pressure under the compression action, forming a sealing ring around the connector 2, which can effectively prevent water from invading the electrical contact area of ​​the connector 2 from the gap inside the waterproof housing 1.

[0049] Working principle: When using this waterproof connector, first, the wire 11 to be connected is passed through the sealing gasket 10 on the outside of the left waterproof housing 1. Since the sealing gasket 10 is made of elastic material, it can tightly wrap the wire 11 to prevent moisture from seeping in from the inlet of the wire 11. Then, the wire 11 is electrically connected to the connector 2 inside the waterproof housing 1. Next, the connector 2 slides inside the limit support 6 through the limit connector 7, moving it into the interior of the waterproof housing 1. The limit support 6 and the limit connector 7 slide together to ensure that the connector 2 is accurately positioned during installation. At the same time, the connecting rod 9 is passed through the mounting hole inside the auxiliary gasket 8 and threaded into the mounting groove of the limit connector 7. Then, the connecting rod 9 is rotated to lock the limit connector 7 in place. Connector 7 and waterproof housing 1 are connected to ensure the connector 2 is securely installed, preventing loosening due to vibration or other factors. After connection, the two waterproof housings 1 are aligned, and then the waterproof sealing plate 402 is rotated on the rotating seat 401 so that it is positioned on top of the fixed seat 403, with the slot inside the fixed seat 403 aligned with the sliding groove of the waterproof sealing plate 402. Next, the fixed support rod 406 is moved upward, causing the fixed support rod 406 to drive the reset support plate 407 to slide upward inside the support seat 405. At this time, the reset support plate 407 drives the reset spring 408 to move upward, compressing the reset spring 408. Then, the connecting seat 404 is rotated on the fixed seat 403 so that the fixed support rod 406 is positioned on top of the slot in the fixed seat 403. Next, the fixed support rod 406 is released, and the return spring 408 immediately releases its pressure, which in turn moves the return plate 407 downward. At this time, the return plate 407 moves the fixed support rod 406 downward, and then the locking block at the bottom of the fixed support rod 406 moves downward. The locking block at the bottom of the fixed support rod 406 passes through the sliding groove of the waterproof sealing plate 402 and engages with the internal locking groove of the fixed seat 403 to fix the waterproof sealing plate 402, thereby firmly fixing the waterproof sealing plate 402 and forming a waterproof barrier. The elastic force provided by the return spring 408 ensures that the fixed support rod 406 always remains in the locked state and will not loosen even in a vibration environment. When the connector is in working condition, the signal on / off indicator light 13 on the right waterproof housing 1 will light up according to the connection status. Different colored lights illuminate the connector, with green indicating a normal connection and red indicating a disconnection or malfunction, allowing operators to monitor the connector's operation in real time. During use, the humidity sensor 502 continuously monitors the humidity inside the waterproof housing 1. When the ambient humidity rises or condensation occurs due to temperature changes, the humidity sensor 502 detects that the humidity exceeds a preset threshold, triggering the start of the fan body 507. The fan body 507 is located inside the ventilation housing 506. After starting, it draws in outside air through the dustproof plate 508 at the bottom of the ventilation housing 506. The dustproof plate 508 prevents dust and other impurities from entering, ensuring clean air intake. The air then passes through the ventilation plate 505 into the placement box 503, where a desiccant can be placed.The air is dehumidified, and the dried air then enters the waterproof housing 1 through the ventilation plate 505, forming an air circulation, thereby reducing the humidity inside the housing and preventing problems such as short circuits or poor contact caused by moisture. Operators can pull the pull rod 504 on the outside of the placement box 503 to remove it from the support base 501 for easy replacement of expired desiccant, ensuring dehumidification effectiveness. Furthermore, when it is necessary to disassemble the connector, simply pull the fixing rod 406 upwards to compress the return spring 408, disengaging it from the slot of the fixing base 403, and then rotate the waterproof sealing plate 402 to open the top, facilitating inspection or reconnection of the internal connector 2.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
