Description

Technical Field

[0001] This invention belongs to the technical field of wet-plug optical connectors, specifically, it relates to a wet-plug optical connector with a self-cleaning function. Background Technology

[0002] Underwater wet-molded connectors are widely used in seabed observation networks, offshore drilling platforms, underwater robots, and various marine towed equipment. The demand for underwater wet-molded connectors is increasing, especially with the construction and implementation of projects such as seabed scientific observation networks. During the use of these critical facilities, higher requirements are placed on the performance indicators, reliability, and service life of the connectors.

[0003] For underwater wet-mating optical connectors, insertion loss and return loss of the fiber optic connectors are two of the most critical performance indicators, and the cleanliness of the connectors significantly impacts these parameters. Underwater wet-mating connectors' fiber optic connectors are constantly immersed in silicone oil, making them impossible to clean like land-based connectors. Furthermore, the complex and variable underwater environment inevitably leads to varying degrees of contamination in the fiber optic connectors after repeated insertions and removals. This increases insertion and return loss, resulting in reduced transmission distance, higher bit error rates, and even communication failure.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] This invention proposes a wet-plug optical connector with a self-cleaning function to solve the technical problem that fiber optic connector contamination leads to reduced transmission distance, increased communication error rate, and even communication failure.

[0006] To achieve the above-mentioned invention / design objectives, the present invention adopts the following technical solution: A wet-plug optical connector with a self-cleaning function, the optical connector including a first connection terminal and a second connection terminal; The first connection terminal includes: First outer shell; The first inner core is located inside the first outer shell and is fixedly connected to the first outer shell. The first inner core is provided with a drive component shuttle hole. The first optical connection terminal is located inside the first housing. A first cylindrical sealing plug is rotatably assembled with the first inner core, and the first cylindrical sealing plug includes a plurality of first through holes; A cleaning assembly is located between the first optical connection end and the first cylindrical sealing plug. The cleaning assembly includes a cleaning cylinder and a cleaning component. A portion of the cleaning component is wound around the cleaning cylinder, and the cleaning component is provided with several cleaning through holes. The second connection terminal includes: Second outer shell; The second inner core is located inside the second outer shell and is slidably connected to the second outer shell. An elastic buffer element is provided between the second inner core and the second outer shell. The second inner core is provided with a drive member shuttle hole. The second optical connector is installed inside the second housing. The second cylindrical sealing plug is rotatably assembled with the second inner core, and the second cylindrical sealing plug includes a plurality of second through holes; A drive unit is installed inside the second housing and can move through the drive unit shuttle hole; the drive unit is used to drive the first cylindrical sealing plug, the second cylindrical sealing plug and the cleaning cylinder to rotate. When the first connecting terminal is connected to the second connecting terminal, the second connecting terminal contacts the second inner core and pushes the second inner core into the second outer shell, squeezing the elastic buffer element. The driving member drives the first cylindrical sealing plug and the second cylindrical sealing plug to rotate to the state where the first through hole and the second through hole are connected. The second optical connecting end passes through the second through hole and the first through hole and contacts the part of the cleaning member that does not have a cleaning through hole. The driving member drives the cleaning cylinder to rotate until the cleaning through hole is opposite to the second optical connecting end. After the second optical connecting end passes through the cleaning through hole, it docks with the first optical connecting end. When the first connecting terminal separates from the second connecting terminal, the second optical connecting terminal separates from the first optical connecting terminal, the second optical connecting terminal exits the cleaning through hole, the driving member drives the cleaning cylinder to rotate until the cleaning through hole is not opposite to the second optical connecting terminal, the second optical connecting terminal exits the first through hole and the second through hole, and the driving member drives the first cylindrical sealing plug and the second cylindrical sealing plug to rotate until the first through hole and the second through hole are not connected.

[0007] As described above, the wet-plug optical connector with built-in cleaning function includes a first cleaning tube and a second cleaning tube. When the first connecting terminal is connected to the second connecting terminal, and when the first connecting terminal is separated from the second connecting terminal, the cleaning component is wound from the second cleaning tube to the first cleaning tube.

[0008] As described above, the wet-plug optical connector with built-in cleaning function includes a rotating wheel coaxially arranged with the first cleaning cylinder, and a linkage rod is provided on the rotating wheel; The driving component is provided with a sliding groove that cooperates with the linkage rod. The sliding groove includes an inclined sliding groove that is set at a certain angle to the driving component. One end of the sliding groove is an open end, and the open end is located at the free end of the driving component. When the first connecting terminal is connected to the second connecting terminal, the free end of the driving member reaches the position of the linkage rod. The linkage rod enters the slide groove from the open end. When the linkage rod slides along the inclined slide groove, the linkage rod drives the rotating wheel to rotate.

[0009] As described above, in the wet-plug optical connector with built-in cleaning function, when the linkage rod enters the slide groove and reaches the position where the first connecting terminal and the second connecting terminal are connected, the first cleaning cylinder rotates half a turn in the first rotation direction. When the first connecting terminal and the second connecting terminal are completely separated from the connection position, the first cleaning cylinder rotates half a turn in the first rotation direction. When the first cleaning cylinder rotates half a turn, the distance that the first cleaning cylinder drives the cleaning through hole to move is half the distance between two adjacent cleaning through holes.

[0010] As described above, in the wet-plug optical connector with self-cleaning function, the slide includes a parallel slide parallel to the drive member, the parallel slide is connected to the inclined slide, and when the first connection terminal and the second connection terminal are connected, the linkage rod at least partially enters the parallel slide.

[0011] As described above, in the wet-plug optical connector with self-cleaning function, the driving component includes an upper driving component and a lower driving component. The upper driving component is used to drive the second cylindrical sealing plug and the first cleaning cylinder to rotate, and the lower driving component is used to drive the first cylindrical sealing plug to rotate.

[0012] As described above, in the wet-plug optical connector with built-in cleaning function, the number of cleaning through holes between the first cleaning cylinder and the second cleaning cylinder is the same as the number of the second optical connection end, the number of the first through hole, and the number of the second through hole, and the spacing between adjacent cleaning through holes is the same as the spacing between adjacent second optical connection ends, the spacing between adjacent first through holes, and the spacing between adjacent second through holes.

[0013] As described above, the wet-plug optical connector with self-cleaning function has a second inner core with a second optical connection end shuttle channel, and the second optical connection end can shuttle within the second optical connection end shuttle channel.

[0014] As described above, the wet-plug optical connector with self-cleaning function has a second optical connection end shuttle channel in the first inner core, and the second optical connection end can shuttle within the second optical connection end shuttle channel.

[0015] As described above, the wet-plug optical connector with self-cleaning function has lugs on both the first cylindrical sealing plug and the second cylindrical sealing plug.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The wet-plug optical connector with built-in cleaning function of the present invention includes a first connection terminal and a second connection terminal. A cleaning component is disposed within the first connection terminal, located between the first optical connection end and the first cylindrical sealing plug. The cleaning component includes a cleaning cylinder and a cleaning element, with a portion of the cleaning element wrapped around the cleaning cylinder. The cleaning element has several cleaning through holes. When the first connection terminal is connected to the second connection terminal, the second connection terminal contacts the second inner core and pushes the second inner core into the second outer shell. The driving component drives the first and second cylindrical sealing plugs to rotate until the first through hole and the second through hole are connected. The second optical connection end passes through the second through hole and the first through hole and contacts the part of the cleaning element without cleaning through holes. The driving component drives the cleaning cylinder to rotate until the cleaning through hole is opposite to the second optical connection end. After passing through the cleaning through hole, the second optical connection end docks with the first optical connection end. Therefore, the first optical connection end can be cleaned by the cleaning element. After cleaning, the cleaning through hole is aligned with the second optical connection end so that the second optical connection end can pass through the cleaning through hole and dock with the first optical connection end. This invention can automatically clean the second optical connection end when the first connection terminal is connected to the second connection terminal, without hindering the docking of the second optical connection end with the first optical connection end. It ensures that the second optical connection end is cleaned before each docking, which can effectively reduce the probability of fiber end face contamination and ensure communication effect.

[0035] The wet-plug optical connector with built-in cleaning function includes a cleaning component that can clean the optical connector end to reduce contamination, avoid insertion loss and return loss, and ensure transmission distance and communication quality.

[0036] The following description, with reference to the accompanying drawings, explains the wet-plug optical connector with built-in cleaning function: like Figures 1-9 As shown, the wet-plug optical connector with self-cleaning function includes a first connection terminal and a second connection terminal.

[0037] The first connection terminal includes a first housing 11, a first inner core 12, a first optical connection end 13, a first cylindrical sealing plug 14, and a cleaning component 15.

[0038] The first outer shell 11 forms the shape of the first connecting terminal. The first outer shell 11 is barrel-shaped, and one end of the first outer shell 11 is an open end.

[0039] The first inner core 12 is located inside the first outer shell 11 and is fixedly connected to the first outer shell 11. The first inner core 12 is partially exposed at the opening end of the first outer shell 11, and the first inner core 12 has a first exposed surface exposed at the opening end.

[0040] The first inner core 12 is provided with a drive component shuttle hole 121, which provides shuttle space for the drive component.

[0041] The first cylindrical sealing plug 14 is rotatably assembled with the first inner core 12. The first cylindrical sealing plug 14 includes a plurality of first through holes 141, and first rotating shafts 142 are provided at both ends of the first cylindrical sealing plug 14.

[0042] The first inner core 12 has a first mounting cavity for mounting the first cylindrical sealing plug 14 and a rotating shaft cavity for mounting the first rotating shaft 142. The first mounting cavity is exposed from the first exposed surface. The first cylindrical sealing plug 14 is mostly located in the first mounting cavity and a small portion protrudes from the first exposed surface.

[0043] The first cylindrical sealing plug 14 is provided with a first lug 143, which drives the first cylindrical sealing plug 14 to rotate.

[0044] The first optical connector 13 is located inside the first housing 11. The first optical connector 13 can be installed on the first housing 11, or it can be installed on the first inner core 12. The first optical connector 13 is a female connector.

[0045] The first inner core 12 is provided with a second optical connector shuttle channel 122, within which the second optical connector 23 can shuttle. The second optical connector shuttle channel 122 can also limit and guide the second optical connector 23.

[0046] The cleaning assembly 15 is located between the first optical connection end 13 and the first cylindrical sealing plug 14. The cleaning assembly 15 includes a cleaning cylinder and a cleaning component 153. Part of the cleaning component 153 is wound around the cleaning cylinder, and the cleaning component 153 is provided with a plurality of cleaning through holes 1531. The positions on the cleaning component 153 without cleaning through holes 1531 are used for cleaning the second optical connection end 23, and the cleaning through holes 1531 are used for the second optical connection end 23 to pass through.

[0047] The second connection terminal includes a second housing 21, a second inner core 22, a second optical connection end 23, a second cylindrical sealing plug 24, and a driving component.

[0048] The second housing 21 forms the shape of the second connecting terminal. The second housing 21 is barrel-shaped, and one end of the second housing 21 is an open end.

[0049] The second inner core 22 is located inside the second outer shell 21 and is slidably connected to the second outer shell 21. That is, the second inner core 22 is axially slidably connected to the second outer shell 21, while the radial direction of the two remains unchanged.

[0050] The second inner core 22 is partially exposed at the opening end of the second outer shell 21, and the second inner core 22 has a second exposed surface exposed at the opening end.

[0051] An elastic buffer element 25 is provided between the second inner core 22 and the second outer shell 21.

[0052] The second inner core 22 is provided with a drive component shuttle hole 221, which provides shuttle space for the drive component.

[0053] The second cylindrical sealing plug 24 is rotatably assembled with the second inner core 22. The second cylindrical sealing plug 24 includes a plurality of second through holes 241, and the two ends of the second cylindrical sealing plug 24 are provided with second rotating shafts 242.

[0054] The second inner core 22 has a second mounting cavity for mounting the second cylindrical sealing plug 24 and a shaft cavity for mounting the second rotating shaft 242. The second mounting cavity is exposed from the second exposed surface, and most of the second cylindrical sealing plug 24 is located in the second mounting cavity, with a small portion protruding from the second exposed surface.

[0055] The second cylindrical sealing plug 24 is provided with a second lug 243, which drives the second cylindrical sealing plug 24 to rotate.

[0056] The second optical connector 23 is installed inside the second housing 21, and the second optical connector 23 is a male connector.

[0057] The second inner core 22 is provided with a second optical connector shuttle channel 222, within which the second optical connector 23 can move. The second optical connector shuttle channel 222 can also limit and guide the second optical connector 23.

[0058] The drive component is installed inside the second housing 21, and the drive component can shuttle through the drive component shuttle hole 221 and the drive component shuttle hole 121; the drive component shuttle hole 221 and the drive component shuttle hole 121 play a guiding and limiting role for the drive component.

[0059] The driving component is used to drive the first cylindrical sealing plug 14, the second cylindrical sealing plug 24 and the cleaning cylinder to rotate.

[0060] The driving component drives the first cylindrical sealing plug 14 and the second cylindrical sealing plug 24 to rotate so as to achieve the connection or non-connection between the first through hole 141 and the second through hole 241. When the first through hole 141 and the second through hole 241 are connected, the second optical connection end 23 can pass through the first through hole 141 and the second through hole 241. When the first through hole 141 and the second through hole 241 are not connected, the first cylindrical sealing plug 14 can be sealed with the first inner core 12 and the second cylindrical sealing plug 24 can be sealed with the second inner core 22.

[0061] When the first connecting terminal is connected to the second connecting terminal, the second connecting terminal contacts the second inner core 22 and pushes the second inner core 22 into the second outer shell 21, squeezing the elastic buffer element 25. The driving member drives the first cylindrical sealing plug 14 and the second cylindrical sealing plug 24 to rotate to the state where the first through hole 141 and the second through hole 241 are connected. The second optical connecting end 23 passes through the second through hole 241 and the first through hole 141 and contacts the part of the cleaning member 153 that does not have a cleaning through hole 1531. The driving member drives the cleaning cylinder to rotate until the cleaning through hole 1531 is opposite to the second optical connecting end 23. After the second optical connecting end 23 passes through the cleaning through hole 1531, it docks with the first optical connecting end 13.

[0062] When the first connecting terminal separates from the second connecting terminal, the second optical connecting end 23 separates from the first optical connecting end 13. The second optical connecting end 23 exits the cleaning through hole 1531. The driving member drives the cleaning cylinder to rotate until the cleaning through hole 1531 is not opposite to the second optical connecting end 23. The second optical connecting end 23 exits the first through hole 141 and the second through hole 241. The driving member drives the first cylindrical sealing plug 14 and the second cylindrical sealing plug 24 to rotate until the first through hole 141 and the second through hole 241 are not connected. The second inner core 22 is reset under the action of the elastic buffer element 25.

[0063] The cleaning cylinder includes a first cleaning cylinder 151 and a second cleaning cylinder 152. When the first connecting terminal is connected to the second connecting terminal, and when the first connecting terminal is separated from the second connecting terminal, the cleaning component 153 is wound from the second cleaning cylinder 152 to the first cleaning cylinder 151. This ensures that the cleaning component 153 used for cleaning is wound into the first cleaning cylinder 151, thereby realizing the recycling of the cleaning component 153, extending the service life of the cleaning components, and eliminating the need for frequent replacement of the cleaning component 153.

[0064] The cleaning assembly includes a rotating wheel 154 coaxially arranged with the first cleaning cylinder 151, and a linkage rod 155 is provided on the rotating wheel 154. The linkage rod 155 is coaxially arranged with the rotating wheel 154 and the first cleaning cylinder 151.

[0065] The driving component includes an upper driving component 261 and a lower driving component 262. The driving component is provided with a sliding groove 2611 that cooperates with the linkage rod 155. The following description takes the upper driving component 261 with a sliding groove 2611 that cooperates with the linkage rod 155 as an example. The sliding groove 2611 includes an inclined sliding groove 26111 set at a certain angle on the upper driving component 261. One end of the sliding groove 2611 is an open end 26113, which is located at the free end of the upper driving component 261.

[0066] The slide 2611 includes a parallel slide 26112 parallel to the upper drive member 261. The parallel slide 26112 is connected to the inclined slide 26111. When the first connecting terminal and the second connecting terminal are connected, the linkage rod 155 at least partially enters the parallel slide 26112.

[0067] When the first connecting terminal is connected to the second connecting terminal, the free end of the upper driving member 261 reaches the position of the linkage rod 155. The linkage rod 155 enters the slide groove 2611 from the open end 26113. When the linkage rod 155 slides along the inclined slide groove 26111, the linkage rod 155 drives the rotating wheel 154 to rotate.

[0068] The upper drive unit 261 is used to drive the second cylindrical sealing plug 24 and the first cleaning cylinder 151 to rotate, and the lower drive unit 262 is used to drive the first cylindrical sealing plug 14 to rotate.

[0069] When the linkage rod 155 enters the slide groove 2611 and reaches the position where the first connecting terminal and the second connecting terminal are connected, the first cleaning cylinder 151 rotates half a turn in the first rotation direction. When the first connecting terminal and the second connecting terminal are completely separated from the connection position, the first cleaning cylinder 151 rotates half a turn in the first rotation direction.

[0070] When the first cleaning cylinder 151 rotates half a turn, the distance that the first cleaning cylinder 151 moves the cleaning through hole 1531 is half the distance between two adjacent cleaning through holes 1531.

[0071] Both the upper drive member 261 and the lower drive member 262 are provided with protrusions that drive the lug of the cylindrical sealing plug to rotate.

[0072] The number of cleaning through holes 1531 between the first cleaning cylinder 151 and the second cleaning cylinder 152 is the same as the number of second optical connection ends 23, the number of first through holes 141, and the number of second through holes 241. The spacing between adjacent cleaning through holes 1531 is the same as the spacing between adjacent second optical connection ends 23, the spacing between adjacent first through holes 141, and the spacing between adjacent second through holes 241.

[0073] When the first connecting terminal and the second connecting terminal are not connected, the second inner core 22 of the second connecting terminal is in the initial state under the action of the elastic buffer element 25; the middle part of the two adjacent cleaning through holes 1531 of the first connecting terminal corresponds to the position of the first through hole 141, and the linkage rod 155 on the rotating wheel 154 is opposite to the drive member shuttle hole 121.

[0074] When the first connecting terminal is connected to the second connecting terminal, the second connecting terminal contacts the second inner core 22 and pushes the second inner core 22 into the second outer shell 21, compressing the elastic buffer element 25. The driving groove of the upper driving member 261 is linked with the second ear 243 of the second cylindrical sealing plug 24, and the driving groove of the lower driving member 262 is linked with the first ear 143 of the first cylindrical sealing plug 14. The first cylindrical sealing plug 14 and the second cylindrical sealing plug 24 rotate to the state where the first through hole 141 and the second through hole 241 are connected, that is, the first through hole 141 and the second through hole 241 are directly connected. The second optical connecting end 23 passes through the second through hole 241 and the first through hole 141 and is connected to the cleaning member 153 which does not have a cleaning through hole 1531. The upper drive component 261's slide groove 2611 contacts the linkage rod 155. The linkage rod 155 slides in the inclined slide groove 26111, driving the rotating wheel 154 to rotate, thereby driving the first cleaning cylinder 151 to rotate. At the same time, the second cleaning cylinder 152 follows the rotation and releases a new cleaning component 153, driving the cleaning cylinder to rotate until the cleaning through hole 1531 is opposite to the second optical connection end 23. The linkage rod 155 reaches the parallel slide groove 26112, and the second optical connection end 23 passes through the cleaning through hole 1531 and docks with the first optical connection end 13.

[0075] When the first connecting terminal separates from the second connecting terminal, the second optical connecting end 23 separates from the first optical connecting end 13, and the second optical connecting end 23 exits the cleaning through hole 1531. The linkage rod 155 exits the parallel slide groove 26112 and enters the inclined slide groove 26111. The linkage rod 155 slides in the inclined slide groove 26111, thereby driving the first cleaning cylinder 151 to rotate until the cleaning through hole 1531 is no longer opposite to the second optical connecting end 23, until the linkage rod 155 separates from the slide groove 2611. The second optical connecting end 23 exits the first through hole 141 and the second through hole 241. The driving member drives the first cylindrical sealing plug 14 and the second cylindrical sealing plug 24 to rotate to a state where the first through hole 141 and the second through hole 241 are not connected. The second inner core 22 is reset under the action of the elastic buffer element 25.

[0076] In some other embodiments, ear handles may be provided on both the first and second cleaning cylinders. The driving component is linked with the ear handles of the first and second cleaning cylinders. When the first connecting terminal is connected to the second connecting terminal, the cleaning component is wound from the second cleaning cylinder to the first cleaning cylinder. When the first connecting terminal is separated from the second connecting terminal, the cleaning component is wound from the first cleaning cylinder to the second cleaning cylinder. This method cannot replace the cleaning component in a timely manner, resulting in a reduced lifespan of the cleaning component, and the cleaning component needs to be replaced frequently.

[0077] At this time, the upper driving member is used to drive the second cylindrical sealing plug and the first cleaning cylinder to rotate, and the lower driving member is used to drive the first cylindrical sealing plug and the second cleaning cylinder to rotate.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
