Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment technology, and in particular to a novel sealed and waterproof connector assembly. Background Technology

[0002] In modern industry, electronic equipment, and new energy fields, connectors are key components for achieving electrical connections, and their performance directly affects the reliability and safety of the system. Especially in underwater operations, humid environments, or outdoor equipment applications, the waterproof sealing performance of connectors is crucial. If the connector seal fails, moisture intrusion can lead to electrical short circuits, component corrosion, and even equipment malfunctions and safety accidents. Therefore, developing highly reliable, sealed, and waterproof connector assemblies has become a core requirement for ensuring the stable operation of equipment.

[0003] Currently, most waterproof connectors on the market employ a single sealing structure, such as relying solely on O-rings for waterproofing. The technical principle is to compress the O-ring, causing it to fill the gap between the male and female ends of the connector, forming a physical barrier to prevent moisture from entering. In addition, some connectors use simple snap-fit ​​or threaded locking methods to secure the male and female ends, using mechanical force to maintain the compression of the seal. These traditional structures prioritize the achievement of basic sealing functions in their design, meeting waterproofing requirements under normal conditions through standardized seals and fixing methods.

[0004] However, traditional waterproof connectors have significant drawbacks when facing complex operating conditions such as vibration, impact, or assembly tolerances. Because a single sealing structure lacks dynamic compensation capabilities, when the connector is subjected to external vibration or mechanical stress generated by equipment operation, slight displacement can easily occur between the male and female ends, leading to insufficient seal compression and subsequent water leakage. Simultaneously, dimensional tolerances during assembly also affect the initial compression state of the seal; if tolerances are not properly controlled, there is a risk of seal failure even under static conditions. Therefore, a novel sealed waterproof connector assembly is proposed to address these issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a novel sealed and waterproof connector assembly, which aims to improve the problem in the prior art where, when the connector is subjected to external vibration or mechanical stress generated by equipment operation, a small displacement easily occurs between the male and female ends, resulting in insufficient sealing compression and subsequent water leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel sealed and waterproof connector assembly includes a female base, a tolerance head that is slidably connected inside the female base, a sealing component provided on the side wall of the tolerance head, and a fixing component provided on the side wall of the tolerance head;

[0008] The sealing assembly includes a corrugated sealing ring, the inner wall of which is slidably connected to the side wall of the tolerance head. The side wall of the tolerance head has an installation groove. An O-ring is provided inside the female seat. A fixing sleeve is fixedly connected inside the female seat. A connecting ring is slidably connected inside the fixing sleeve. A push plate is fixedly connected to the side wall of the connecting ring. A spring is provided inside the fixing sleeve. One end of the spring is fixedly connected inside the fixing sleeve, and the other end of the spring is fixedly connected to the side wall of the connecting ring. The side wall of the push plate is attached to one side of the O-ring, and the side wall of the tolerance head is attached to the other side of the O-ring.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes an elastic plate and a connecting sleeve. The side wall of the elastic plate is fixedly connected to the side wall of the tolerance head, and the side wall of the connecting sleeve is fixedly connected to the side wall of the female seat. The side wall of the elastic plate is slidably connected inside the connecting sleeve, and the side wall of the tolerance head is slidably connected inside the connecting sleeve.

[0011] As a further description of the above technical solution:

[0012] The corrugated sealing ring sidewall is slidably connected to the mounting groove sidewall, and the corrugated sealing ring sidewall is slidably connected to the inside of the female seat.

[0013] As a further description of the above technical solution:

[0014] The elastic plate has a locking block fixedly connected to its side wall, and the connecting sleeve has a locking groove inside, with the locking block's side wall slidably connected inside the locking groove.

[0015] As a further description of the above technical solution:

[0016] An installation sleeve is fixedly connected to the side wall of the connecting sleeve, and a fixing seat is fixedly connected inside the installation sleeve.

[0017] As a further description of the above technical solution:

[0018] A fixing block is slidably connected inside the mounting sleeve, and the side wall of the fixing block is slidably connected inside the connecting sleeve.

[0019] As a further description of the above technical solution:

[0020] The mounting sleeve contains a second spring. One end of the second spring is fixedly connected to the side wall of the fixing seat, and the other end of the second spring is fixedly connected to the side wall of the fixing block.

[0021] As a further description of the above technical solution:

[0022] The tolerance head has a fixing groove on its side wall, and the fixing block is slidably connected to the inside of the fixing groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by inserting the tolerance head into the female seat, the corrugated sealing ring fits against the inner wall of the female seat due to its own elasticity. At the same time, the side wall of the tolerance head pushes the O-ring sealing ring to fit tightly against the gap between the tolerance head and the female seat, forming a second waterproof barrier. This solves the problem that when the connector is subjected to external vibration or mechanical stress generated by the operation of the equipment, the male and female ends are prone to slight displacement, resulting in insufficient compression of the sealing element and water leakage from the gap. The above structure improves the sealing effect of the equipment.

[0025] 2. In this utility model, by inserting the tolerance head into the female seat, the elastic plate slides into the inside of the connecting sleeve and undergoes elastic bending. When the locking block aligns with the locking groove inside the connecting sleeve, the elastic plate returns to its original shape, and the locking block is locked into the locking groove. As the tolerance head continues to be inserted, its side wall pushes the fixing block to compress the second spring, causing the fixing block to slide along the inside of the mounting sleeve. When the tolerance head is inserted into place, the fixing block, under the elastic force of the second spring, is locked into the fixing groove on the side wall of the tolerance head, further restricting the radial and axial movement of the tolerance head and greatly improving the connection stability of the connector under vibration, impact and other working conditions.

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a novel sealed and waterproof connector assembly, including a female base 1. The female base 1 provides the basic mounting structure for the connector, serving to support internal components and connect with external devices, ensuring the overall stability of the connector. A tolerance head 2 is slidably connected inside the female base 1, used to mate with external connecting components. A sealing component is provided on the side wall of the tolerance head 2 to prevent moisture from entering the connector and ensuring the safety of the electrical connection. A fixing component is provided on the side wall of the tolerance head 2 to enhance the connection stability between the tolerance head 2 and the female base 1, preventing loosening of the connection due to vibration or other factors.

[0035] The sealing assembly includes a corrugated sealing ring 4, which fills the gap between the tolerance head 2 and the female seat 1. Utilizing its elastic deformation, it forms the first waterproof barrier, effectively preventing water penetration and providing a good seal. The inner wall of the corrugated sealing ring 4 is slidably connected to the side wall of the tolerance head 2. The side wall of the tolerance head 2 has an installation groove 3, which is used to fix the position of the corrugated sealing ring 4, restricting its radial movement and ensuring that the corrugated sealing ring 4 is always in an effective sealing position, improving sealing reliability. An O-ring 5 is provided inside the female seat 1. After the tolerance head 2 is inserted into the female seat 1, the O-ring 5 further fills the tiny gaps between them, forming a second waterproof barrier. Together with the corrugated sealing ring 4, it forms double waterproof protection, significantly improving waterproof performance. A fixing sleeve 6 is fixedly connected inside the female seat 1. A connecting ring 7 is slidably connected inside the fixing sleeve 6. A push plate 8 is fixedly connected to the side wall of the connecting ring 7. The connecting ring 7 slides inside the fixing sleeve 6 in conjunction with the insertion movement of the tolerance head 2, driving the push plate 8. Synchronous movement achieves the effect of providing continuous pressure to the O-ring 5. A spring 9 is installed inside the fixed sleeve 6. One end of the spring 9 is fixedly connected to the inside of the fixed sleeve 6, and the other end of the spring 9 is fixedly connected to the side wall of the connecting ring 7. The function of the spring 9 is to be compressed and store elastic potential energy during the insertion of the tolerance head 2. When the connector is subjected to external force, causing the tolerance head 2 and the female seat 1 to be displaced, the elastic potential energy is released to compensate for the displacement and maintain the compression state of the O-ring 5. The side wall of the push plate 8 is attached to one side of the O-ring 5, and the side wall of the tolerance head 2 is attached to the other side of the O-ring 5. The push plate 8 and the tolerance head 2 together compress the O-ring 5, making it tightly attached to the gap between them, so as to achieve a reliable seal. The side wall of the corrugated sealing ring 4 is slidably connected to the side wall of the mounting groove 3 and the inside of the female seat 1. Through this cooperation, the corrugated sealing ring 4 can always maintain close contact with the inner wall of the female seat 1 during the insertion and use of the tolerance head 2, effectively playing a waterproof role.

[0036] Reference Figure 2 and Figure 5The fixing assembly includes an elastic plate 10 and a connecting sleeve 11. The elastic plate 10 is used to elastically deform during the insertion of the tolerance head 2 into the female seat 1, playing a buffering and guiding role to ensure smooth insertion of the tolerance head 2. It also provides restoring force to assist in fixing after insertion. The side wall of the elastic plate 10 is fixedly connected to the side wall of the tolerance head 2, and the side wall of the connecting sleeve 11 is fixedly connected to the side wall of the female seat 1. The side wall of the elastic plate 10 is slidably connected inside the connecting sleeve 11, and the side wall of the tolerance head 2 is slidably connected inside the connecting sleeve 11. The connecting sleeve 11 slides, guiding the tolerance head 2 to accurately insert into the female seat 1 and initially restricting the radial movement of the tolerance head 2. A locking block 12 is fixedly connected to the side wall of the elastic plate 10. A slot 13 is provided inside the connecting sleeve 11 to provide embedding space for the locking block 12. The engagement of these two components achieves initial fixation between the tolerance head 2 and the female seat 1, improving the connector's resistance to pull-out. A mounting sleeve 14 is fixedly connected to the side wall of the connecting sleeve 11, and a fixing device is fixedly connected inside the mounting sleeve 14. The mounting sleeve 14 has a fixed block 17 slidably connected inside the mounting sleeve 14. The side wall of the fixed block 17 is slidably connected inside the connecting sleeve 11. It can cooperate and separate from the fixed groove 18 by sliding inside the connecting sleeve 11, which is flexible and convenient. The mounting sleeve 14 has a second spring 16 inside. One end of the second spring 16 is fixedly connected to the side wall of the mounting sleeve 15, and the other end of the second spring 16 is fixedly connected to the side wall of the fixed block 17. The function of the second spring 16 is to be compressed during the insertion of the tolerance head 2 and store elastic potential energy. When the tolerance head 2 is inserted into place, the second spring 16 releases the elastic potential energy to push the fixed block 17 into the fixed groove 18. The side wall of the tolerance head 2 has a fixed groove 18, which is used to cooperate with the fixed block 17. After the two are engaged, a stable connection structure is formed, which significantly improves the connector's anti-loosening ability under complex working conditions such as vibration and impact. The side wall of the fixed block 17 is slidably connected inside the fixed groove 18. Through this cooperation, the tolerance head 2 and the female seat 1 are tightly fixed, which effectively ensures the connection reliability of the connector during use.

[0037] Working Principle: When the device is in operation, as the tolerance head 2 is inserted into the female seat 1, the corrugated sealing ring 4 in the mounting groove 3, due to its elasticity, tightly adheres to the inner wall of the female seat 1, forming the first waterproof barrier. Simultaneously, the side wall of the tolerance head 2 pushes the O-ring seal 5, causing it to elastically deform and tightly adhere to the gap between the tolerance head 2 and the female seat 1, forming the second waterproof barrier. During the insertion of the tolerance head 2, its side wall pushes the connecting ring 7 to slide along the inside of the fixing sleeve 6, compressing the spring 9. The elastic force generated by the spring 9 continuously applies pressure to the O-ring seal 5 through the connecting ring 7 and the push plate 8. When the connector is subjected to external forces such as vibration or water pressure, causing a slight displacement between the tolerance head 2 and the female seat 1, the spring 9 can dynamically compensate for the displacement through its own deformation, maintaining the compressed state of the O-ring seal 5 and ensuring stable sealing performance. When the tolerance head 2 is inserted into the female seat 1, the elastic plate 10 on the side wall slides into the connecting sleeve 11. The elastic plate 10 undergoes elastic bending. When the locking block 12 on the elastic plate 10 aligns with the locking groove 13 inside the connecting sleeve 11, the elastic plate 10 returns to its original shape, and the locking block 12 engages with the locking groove 13, forming a mechanical limit to prevent the tolerance head 2 from axially disengaging from the female seat 1. As the tolerance head 2 continues to be inserted, its side wall pushes the fixing block 17 to compress the second spring 16, causing the fixing block 17 to slide along the inside of the mounting sleeve 14. When the tolerance head 2 is inserted into place, the fixing block 17, under the elastic force of the second spring 16, engages with the fixing groove 18 on the side wall of the tolerance head 2, further restricting the radial and axial movement of the tolerance head 2. Together with the elastic plate 10 and the locking block 12, a double fixation is formed, which greatly improves the connection stability of the connector under vibration, impact and other working conditions.
