[0001] This utility model relates to the field of connector technology, specifically to a high-sealing underwater circular connector. Background Technology
[0002] With the accelerating pace of human exploration and development of the ocean and the widespread use of underwater electrical equipment, conventional waterproof connectors can no longer meet the requirements. Underwater connectors, crucial components for connecting underwater electrical systems with surface terminal equipment or power supplies, have gradually developed, and the requirements for them are constantly increasing. Circular connectors are a type of connector with a cylindrical structure and a circular mating surface. In interconnect classifications, they belong to category 5 and are used for interconnecting devices.
[0003] Circular connectors are prone to detachment when used underwater, leading to internal water leakage and causing short circuits and damage to electrical equipment. In addition, when the outer layer of the connector is damaged, it cannot meet the sealing requirements. Therefore, there is an urgent need for high-sealing circular connectors for underwater use to overcome the above defects. Summary of the Invention
[0004] The purpose of this invention is to provide a high-sealing underwater circular connector with the advantages of multi-layer sealing and good fixing effect, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing underwater circular connector, comprising a first male connector assembly, a reinforcing assembly, and a second female connector assembly. The reinforcing assemblies are disposed on the front and back of the first male connector assembly, and the second female connector assembly is disposed on the right side of the first male connector assembly. The first male connector assembly includes a male connector body, a fixed disc seat, a slot, a threaded bracket, a first annular seat, a first sealing ring, a second sealing ring, and a second annular seat. The reinforcing assemblies include an L-shaped seat, a slide groove, a turntable, a threaded rod, a slider, an L-shaped connecting rod, and a rubber block. The second female connector assembly includes a female connector body, an internal threaded seat, a sealing plug, a third sealing ring, a third annular seat, and a fixing ring.
[0006] Furthermore, the fixed plate base is fixedly installed on the surface of the male connector body, the slots are all opened on both sides inside the fixed plate base, and the threaded bracket is set in the inner cavity of the slot.
[0007] Furthermore, the second annular seat is fixedly installed on the right side of the fixed plate seat, the second sealing ring is fixedly installed on the inner surface of the second annular seat, and the first annular seat is fixedly installed on the right side of the male connector body.
[0008] Furthermore, the first sealing ring is sleeved on the surface of the first annular seat, the L-shaped seats are all fixedly installed on both sides of the fixed plate seat, the slide groove is opened inside the L-shaped seat, and the slider slides in the inner cavity of the slide groove.
[0009] Furthermore, the slider is internally connected to a threaded rod via a threaded connection, the turntable is located on the outside of the L-shaped seat, and the threaded rod extends from the side furthest away from the L-shaped seat to the side of the turntable that is closer to it and is fixedly connected.
[0010] Furthermore, the L-shaped connecting rod is fixedly installed on the right side of the slider, the rubber block is fixedly installed on the left side of the L-shaped connecting rod, the female connector body is located on the right side of the male connector body, and the fixing ring is fixedly installed on the surface of the female connector body.

[0013] This invention provides multiple seals at the connection point by incorporating a first male connector assembly and a second female connector assembly, and reinforces the connection point with a reinforcing component. During installation, the female connector body is first inserted into the male connector body. Then, a third sealing ring double-seals the gap between the first annular seat and the surface of the female connector body, preventing moisture from entering the connection. Next, the third annular seat is inserted into the inner cavity of the second annular seat. The first sealing ring seals the gap between the third and first annular seats, and simultaneously, the second sealing ring seals the gap between the third and second annular seats. Finally, the gap between the fixing ring and the second annular seat is sealed by the sealing plug. After sealing, the internal thread seat is inserted into the inner cavity of the slot. Then, the threaded bracket is rotated, and the surface of the threaded bracket is threadedly connected to the inner cavity of the internal thread seat. After fixing, the turntable is rotated, and the turntable drives the threaded rod to rotate, causing the L-shaped connecting rod and the rubber block to move inward, reinforcing the connection between the fixing ring and the fixing plate seat. It has the advantages of multi-layer sealing and good fixing effect, which solves the problem that the circular connector is prone to falling off when used underwater, resulting in internal water leakage and short circuit damage to electrical equipment. At the same time, when the outer layer of the connector is damaged, it cannot meet the sealing requirements. Attached Figure Description
