Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a waterproof and sealed connector. Background Technology

[0002] In many fields such as modern industry, electronic equipment, and transportation, connectors are key components for realizing circuit or signal connections, and their reliability directly affects the normal operation of equipment. With the continuous expansion of application scenarios, many devices need to operate in harsh conditions such as outdoors, in humid environments, or underwater, which places extremely high demands on the waterproof and sealing performance of connectors.

[0003] Currently, most waterproof sealing connectors on the market use a single sealing structure, such as relying solely on a sealing ring. This type of structure is prone to wear and aging of the sealing ring under strong vibrations, high water pressure, or prolonged use, leading to a decline in sealing performance and an inability to effectively prevent moisture ingress. Furthermore, some connectors use a direct plug-in connection method, which makes them extremely susceptible to loosening due to vibrations or external forces during actual use, significantly reducing their waterproof effect. Utility Model Content

[0004] To overcome the aforementioned drawbacks, this utility model provides a waterproof and sealed connector.

[0005] The technical implementation scheme of this utility model is as follows: a waterproof and sealing connector includes a connector body, a rotating block, a threaded sleeve, a locking block and a first spring. The threaded sleeve is movably connected to the outside of the connector body. The right end of the threaded sleeve is connected to the rotating block located outside the connector body. The locking block is slidably connected to the upper end of the rotating block. The first spring is connected between the locking block and the rotating block. A locking hole is opened at the top of the connector body and at the same straight line position as the moving trajectory of the locking block. The locking block and the locking hole are engaged.

[0006] As an improvement to the above solution, a sealing ring is also included, with a sealing ring connected to the left port of the connector body.

[0007] As an improvement to the above solution, the sealing ring is made of elastic sealing materials such as silicone rubber, and its cross-sectional shape is adapted to the mating gap between the connector body and the device interface.

[0008] As an improvement to the above solution, it also includes a fixed block, a second spring, a sliding rod, and a connecting ring. The fixed block is connected to the outside of the threaded sleeve. Multiple sliding rods are slidably connected to the inside of the fixed block along the circumferential direction. A second spring is connected between each sliding rod and the inside of the fixed block. A connecting ring is connected between the left ends of the sliding rods. The connecting ring is sleeved on the outside of the connector body and is coaxial with the connector body.

[0009] As an improvement to the above solution, a sealing ring is also included, with the left end of the connecting ring connected to the sealing ring.

[0010] As an improvement to the above solution, it also includes a support block, a torsion spring, and a sealing cover. The support block is connected to the top left side of the connecting ring, and the sealing cover is rotatably connected to the support block. The sealing cover contacts the left side of the sealing ring, thereby sealing the left port of the connector body. Two torsion springs are connected between the upper end of the sealing cover and the support block.

[0011] The beneficial effects of this utility model are as follows: 1. By screwing the threaded sleeve into the threaded interface of the equipment, the connection between the connector body and the equipment can be further tightened. Compared with the traditional direct plugging method, it can effectively prevent the entry of external dust and moisture, and prevent loosening caused by vibration, external force pulling, etc. At the same time, the locking cooperation between the locking block and the locking hole restricts the movement of the threaded sleeve after it is moved into place, providing double protection for the reliability of the connection and ensuring that the connector works stably under complex working conditions.

[0012] 2. On the one hand, the sealing ring on the left port of the connector body fits tightly against the equipment interface under the tightening force of the threaded sleeve, forming a sealing barrier; on the other hand, the newly added connecting ring and sealing ring structure, when the connector is plugged in, the sealing ring first contacts the outside of the equipment interface, and the elastic force of the second spring makes it fit tightly against the interface, forming a double sealing structure. Multiple lines of defense effectively prevent moisture, dust, oil and other external substances from entering the connection part, protecting the internal circuit and electronic components from corrosion.

[0013] 3. The sealing cap and torsion spring automatically seal the left port of the connector body when it is not connected to the equipment, preventing external dust and moisture from entering. After being removed from the equipment, it can quickly reset and close under the action of the torsion spring, without the need for manual operation. This achieves intelligent protection of the port and effectively improves the overall protection level and service life of the connector. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0020] Example: A waterproof, sealed connector, such as Figures 1-2 As shown, the connector includes a connector body 1, a sealing ring 2, a rotating block 3, a threaded sleeve 4, a locking block 5, and a first spring 6. The threaded sleeve 4 is movably connected to the outside of the connector body 1. The right end of the threaded sleeve 4 is connected to the rotating block 3 located outside the connector body 1. The locking block 5 is slidably connected to the upper end of the rotating block 3. The first spring 6 is connected between the locking block 5 and the rotating block 3. A locking hole 7 is opened at the top of the connector body 1 and at the same straight line position as the moving trajectory of the locking block 5. The locking block 5 can be engaged with the locking hole 7 when it moves to the left. The bottom surface of the locking block 5 is designed with a rounded transition structure to facilitate quick insertion into the locking hole 7. A sealing ring 2 is connected to the left port of the connector body 1. The sealing ring 2 is made of elastic sealing materials such as silicone rubber. Its cross-sectional shape is adapted to the mating gap between the connector body 1 and the device interface to ensure the sealing effect. When the connector body 1 is inserted into the device interface, the sealing ring 2 abuts against the device interface to ensure the tightness between the connector body 1 and the device interface.

[0021] When connecting the connector body 1 to the device interface, the connector body 1 is first directly inserted into the device interface, at which point the threaded sleeve 4 is simultaneously aligned with the external thread structure of the device interface. Subsequently, by rotating the rotating block 3, the threaded sleeve 4 is driven to move to the left along the axial direction of the connector body 1 using the thread transmission principle, so that it engages and tightens with the thread of the device interface. During the movement of the threaded sleeve 4, the locking block 5 moves synchronously with the rotating block 3 and rotates around the axis of the connector body 1. In the initial stage, the locking block 5 is resisted by the connector body 1, and the first spring 6 is in a stretched state. When the threaded sleeve 4 moves to the set position and the locking block 5 is aligned with the axis of the locking hole 7, the first spring 6 releases its elastic potential energy, pushing the locking block 5 downward to engage with the locking hole 7, thereby restricting the axial movement and circumferential rotation of the threaded sleeve 4, ensuring that the threaded sleeve 4 reaches the predetermined tightening position. During this process, the tightening action of the threaded sleeve 4 further tightens the connection between the connector body 1 and the equipment interface. Simultaneously, the sealing ring 2 at the left port of the connector body 1 undergoes elastic deformation under the tightening force of the thread and tightly adheres to the end face and sidewall of the equipment interface, forming multiple sealing barriers. This effectively prevents external substances such as moisture, dust, and oil from entering the connection area, achieving excellent waterproof sealing performance and providing reliable protection for internal circuits and electronic components. When it is necessary to disassemble the connector body 1, the operator pulls the locking block 5 upwards, overcoming the elastic force of the first spring 6 to disengage it from the locking hole 7. At this time, the first spring 6 is in a stretched state again. After releasing the locking restriction, the rotating block 3 is rotated in the opposite direction, causing the threaded sleeve 4 to rotate axially to the right out of the equipment interface. Once the threaded sleeve 4 is completely disengaged from the equipment interface, the connector body 1 can be directly pulled out of the equipment interface, completing the disassembly operation. The entire disassembly process is simple to operate and will not damage the connector or the equipment interface.

[0022] like Figure 1 and Figure 3 As shown, it also includes a fixing block 8, a second spring 9, a sliding rod 10, a connecting ring 11, and a sealing ring 12. The fixing block 8 is welded to the outside of the threaded sleeve 4. Multiple sliding rods 10 are slidably connected circumferentially inside the fixing block 8. The second spring 9 is connected between the sliding rod 10 and the inside of the fixing block 8. The connecting ring 11 is connected between the left ends of the sliding rods 10. The connecting ring 11 is sleeved on the outside of the connector body 1 and is coaxial with the connector body 1. The sealing ring 12 is connected to the left end of the connecting ring 11. The sealing ring 12 is made of high elastic nitrile rubber material, and its inner diameter is adapted to the outer diameter of the equipment interface to achieve an interference fit seal.

[0023] During the connection operation between the connector and the device interface, in the initial state, the left end of the connecting ring 11 extends beyond the left port of the connector body 1 under the preload of the second spring 9. When the connector body 1 approaches the device interface, the sealing ring 12 on the connecting ring 11 contacts the outside of the device interface first. As the insertion action progresses, the sealing ring 12 is compressed and undergoes elastic deformation. At the same time, the sliding rod 10 overcomes the elastic force of the second spring 9 and slides into the fixing block 8, keeping the connecting ring 11 fitted on the outside of the device interface. During this process, the second spring 9 continuously provides a stable axial clamping force, pushing the sealing ring 12 to fit tightly against the outer surface of the device interface. This further protects the connection between the connector body 1 and the interface, significantly improving the waterproof and dustproof performance of the connection part. When the connector body 1 is removed, the connecting ring 11 is no longer under force, the second spring 9 will rebound and reset, driving the sliding rod 10 and the connecting ring 11 to reset, allowing the sealing ring 12 to return to its initial position.

[0024] like Figure 1 and Figure 4 As shown, it also includes a support block 13, a torsion spring 14, and a sealing cover 15. The support block 13 is welded to the top left side of the connecting ring 11. The sealing cover 15 is rotatably connected to the support block 13. The sealing cover 15 contacts the left side of the sealing ring 12, thereby sealing the left port of the connector body 1. Two torsion springs 14 are connected between the upper end of the sealing cover 15 and the support block 13. Under normal conditions, the torsion springs 14 apply a clockwise rotational torque to the sealing cover 15, so that the sealing cover 15 fits tightly against the left side of the sealing ring 12, thus sealing the left port of the connector body 1.

[0025] When this device is needed, the sealing cover 15 must first be rotated upwards to open it, so that it no longer seals the left port of the connector body 1. The torsion spring 14 will deform accordingly. Then the connector body 1 can be inserted into the device interface. The sealing cover 15 remains open due to the obstruction of the device. When the connector body 1 is removed from the device, the sealing cover 15, which has lost its external obstruction, will quickly rotate counterclockwise under the reset torque of the torsion spring 14, and re-fit the left side of the sealing ring 12, sealing the left port of the connector body 1 and preventing external dust, moisture and other contaminants from entering the interior of the connector body 1 when it is not connected.
