[0053] The present embodiment provides a wet optical plug 100 including a male plug 200 and a female plug 300. The male plug 200 includes a main body 210, an active optical fiber 220 and a first sealing block 230. The main body 210 is provided with a first optical fiber channel 211. The active optical fiber 220 is located in the first optical fiber channel 211. The first sealing block 230 is movably arranged at the end of the first optical fiber channel 211. The first sealing block 230 can block or move out of the first optical fiber channel 211. The female plug 300 includes a housing 310, a movable part 320, a fixed optical fiber 330 and a second sealing block 340. The movable part 320 is arranged in the housing 310. The movable part 320 is provided with a second optical fiber channel 321. , the fixed optical fiber 330 is located in the second optical fiber channel 321 and the shell 310, and the second sealing block 340 is movably arranged at the end of the second optical fiber channel, and the second sealing block 340 can block or move out of the second optical fiber channel 321; wherein, when the male plug 200 and the female plug 300 are plugged in, the main body 210 and the movable part 320 abut against each other, the first optical fiber channel 211 and the second optical fiber channel 321 are connected, and the boundary between the first optical fiber channel 211 and the second optical fiber channel 321 is blocked from the outside; the first sealing block 230 and the second sealing block 340 are respectively moved out of the first optical fiber channel 211 and the second optical fiber channel 321, and the movable optical fiber 220 and the fixed optical fiber 330 are connected.

[0054] Specifically, please refer to Figure 5 , the side of the first sealing block 230 is tightly fitted with the inner wall of the first optical fiber channel 211, so that the first optical fiber channel 211 forms a closed space, and the active optical fiber 220 is located in the first optical fiber channel 211, that is, the active optical fiber 220 is located in the closed space; similarly, the side of the second sealing block 340 is tightly fitted with the second optical fiber channel 321, so that the second optical fiber channel 321 forms a closed space, and the fixed optical fiber 330 is located in the second optical fiber channel 321, that is, the fixed optical fiber 330 is located in the closed space; thereby, before the male plug 200 and the female plug 300 are connected, the active optical fiber 220 and the fixed optical fiber 330 are both located in a sealed environment, thereby avoiding blocking seawater and marine life from entering the optical fiber channel, and avoiding affecting the transmission effect of the optical fiber connection and the service life of the optical fiber.

[0055] Please refer to Figure 8 After the male plug 200 and the female plug 300 are docked, the first sealing block 230 moves out of the first optical fiber channel 211, and at the same time, the second sealing block 340 moves out of the second optical fiber channel 321, so that the first optical fiber channel 211 and the second optical fiber channel 321 are connected; and the active optical fiber 220 moves to the position where the first sealing block 230 blocks the first optical fiber channel 211, so that the end of the fixed optical fiber 330 is exposed and connected to the active optical fiber 220.

[0056] It should be noted that, during the docking process, the main body 210 first extends into the shell 310, and the end of the shell 310 is provided with an inclined surface extending away from the center line of the female plug 300 to guide the main body 210 into the shell 310. Then, the main body 210 and the movable member 320 abut together to prevent seawater and marine organisms from entering the optical fiber channel, and finally, the first sealing block 230 and the second sealing block 340 are simultaneously moved out of the first optical fiber channel 211 and the second optical fiber channel 321.

[0057] The working principle of the wet optical plug 100 is:

[0058] Before docking, the first sealing block 230 blocks the first optical fiber channel 211, and the second sealing block 340 blocks the second optical fiber channel 321, thereby forming a closed space, so that the movable optical fiber 220 and the fixed optical fiber 330 are in a sealed environment before docking, so as to avoid the influence of seawater and marine organisms on the transmission effect and service life of the optical fiber before docking.

[0059] During the docking process, the main body 210 extends into the shell 310 and abuts against the movable part 320, so that the critical point between the main body 210 and the movable part 320 is sealed; the main body 210 is continuously pushed along the plugging direction, and the main body 210 drives the movable part 320 to move along the plugging direction, so that the first sealing block 230 moves out of the first optical fiber channel 211, and at the same time, the second sealing block 340 moves out of the second optical fiber channel 321, and the first optical fiber channel 211 and the second optical fiber channel 321 are connected; the main body 210 is continuously pushed along the same direction, and the movable optical fiber 220 moves to the position where the first sealing block 230 blocks the first optical fiber channel 211, wherein, during the movement of the movable part 320, the fixed optical fiber 330 extends relative to the movable part 320, so that the fixed optical fiber 330 is connected to the movable optical fiber 220.

[0060] Finally, after the active optical fiber 220 is connected to the fixed optical fiber 330, that is, after the male plug 200 and the female plug 300 are docked, the male plug 200 and the female plug 300 are locked. At this time, the first optical fiber channel 211 and the second optical fiber channel 321 are blocked from the outside after being connected, thereby forming a closed space, so that the active optical fiber 220 and the fixed optical fiber 330 are still in a sealed environment after the male plug 200 and the female plug 300 are docked, so as to avoid the influence of seawater and marine organisms on the transmission effect and service life of the optical fiber after docking.

[0061] In combination with the above, the female plug 300 further includes a first spring 350, the two ends of which are respectively connected to the movable member 320 and the housing 310, the housing 310 is sleeved on the first spring 350, and the first spring 350 is used to make the movable member 320 have a tendency to move in the direction of the main body 210. When the male plug 200 and the female plug 300 are plugged in, the movable member 320 and the main body 210 abut against each other, and under the action of external force, the movable member 320 moves in the plugging direction relative to the housing 310, thereby compressing the first spring 350, and then when the male plug 200 and the female plug 300 are disconnected, the movable member 320 can move in the pulling-out direction under the action of the rebound force and return to the position before the docking.

[0062] It can be understood that a groove engaged with the movable member 320 is provided on the inner wall of the housing 310 to limit the moving distance of the movable member 320 and prevent the movable member 320 from sliding out.

[0063] Furthermore, the main body 210 is provided with a first accommodating portion 212, which is connected to the first optical fiber channel 211; the movable member 320 is provided with a second accommodating portion 322, which is connected to the second optical fiber channel 321; the first accommodating portion 212 is used to accommodate the first sealing block 230 moved out from the first optical fiber channel 211 when the male plug 200 and the female plug 300 are plugged in and matched; the first accommodating portion 212 is used to accommodate the second sealing block 340 moved out from the second optical fiber channel 321 when the male plug 200 and the female plug 300 are plugged in and matched. Specifically, after the male plug 200 and the female plug 300 are docked, the first sealing block 230 and the second sealing block 340 need to be removed so that the active optical fiber 220 is connected to the fixed optical fiber 330, and the first sealing block 230 is moved from the first optical fiber channel 211 to the first accommodating portion 212, and at the same time, the second sealing block 340 is moved from the second optical fiber channel 321 to the second accommodating portion 322, so that the first optical fiber channel 211 and the second optical fiber channel 321 are opened and connected, and the active optical fiber 220 and the fixed optical fiber 330 are no longer blocked by the first sealing block 230 and the second sealing block 340, thereby connecting the active optical fiber 220 and the fixed optical fiber 330.

[0064] Based on the above settings, please refer to Figure 1-Figure 9The end of the movable optical fiber 220 is provided with a first guide surface 221, and the first guide surface 221 is used to guide the first sealing block 230 to move from the first accommodating portion 212 to the first optical fiber channel 211; the end of the fixed optical fiber 330 is provided with a second guide surface 331, and the second guide surface 331 is used to guide the second sealing block 340 to move from the second optical fiber channel 321 to the second accommodating portion 322. Specifically, in this embodiment, the extension direction of the first guide surface 221 and the extension direction of the second guide surface 331 may form an angle. In other embodiments, the extension direction of the first guide surface 221 and the extension direction of the second guide surface 331 are parallel.

[0065] It should be noted that the second sealing block 340 is provided with a fourth guide surface cooperating with the second guide surface 331, and the extension direction of the fourth guide surface is parallel to the extension direction of the second guide surface 331. When the second sealing block 340 moves out of the second optical fiber channel 321, the second guide surface 331 and the fourth guide surface are in contact with each other.

[0066] For further information, please refer to Figure 5 and Figure 8 , the second sealing block 340 is provided with a boss 341, and the second accommodation portion 322 is provided with a third guide surface 324, the boss 341 abuts against the third guide surface 324, and the third guide surface 324 is used to limit the position of the second sealing block 340 and guide the second sealing block 340 to move to the second accommodation portion 322. Specifically, the second sealing block 340 is provided with a boss 341 above one side close to the end of the second optical fiber channel 321, and the boss 341 abuts against the third wire surface to limit the displacement distance of the second sealing block 340 to prevent the second sealing block 340 from detaching. In this embodiment, the extension direction of the third guide surface 324 and the extension direction of the second wire surface form an angle, and the angle is less than 90 degrees, so that the second sealing block 340 can move from the second optical fiber channel 321 to the second accommodation portion 322. It can be understood that in other embodiments, the extension direction of the third guide surface 324 and the extension direction of the second guide surface 331 can also be parallel.

[0067] According to the above content, the movable member 320 further includes a through hole 325, which is in communication with the second optical fiber channel 321; the through hole 325 is used for the second sealing block 340 to pass through when the female plug 300 is installed; the female plug 300 further includes a blocking member, which cooperates with the through hole 325 and is used to block or open the through hole 325. It can be understood that the through hole 325 is in communication with the second accommodating portion 322.

[0068] Specifically, when installing the female plug 300, first place the second sealing block 340 through the through hole 325 into the second accommodating portion 322, and then install the sealing member to seal the through hole 325. When installing the sealing member, glue can be applied to the gap between the inner wall of the through hole 325 and the sealing member, so that the sealing member and the inner wall of the through hole 325 are connected and the sealing performance is improved. Furthermore, the male plug 200 also includes a moving part 240, and the main body 210 is provided with a accommodating chamber 213, and the accommodating chamber 213 is connected to the first accommodating portion 212; the moving part 240 can be movably arranged in the accommodating chamber 213, and the moving part 240 is connected to the first sealing block 230; the female plug 300 also includes a fixing part 360, the fixing part 360 is connected to the shell 310, and the moving part 320 is provided with a through hole 323 that slidably cooperates with the fixing part 360; wherein, when the male plug 200 and the female plug 300 are plugged in and matched, the moving part 240 and the fixing part 360 abut against each other.

[0069] Specifically, when the male plug 200 and the female plug 300 are plugged in and out, the movable member 320 abuts against the main body 210, and at the same time, the movable member 240 abuts against the fixed member 360. As the staff continues to apply external force to the male plug 200, the movable member 240 moves in the unplugging direction, and the movable member 320 moves in the plugging direction, so that the through hole 323 moves relative to the fixed member 360, so that the fixed member 360 extends out of the through hole 323, and then the movable member 240 can drive the first sealing block 230 to move to the first optical fiber channel 211 and the first accommodating portion 212, so that the first optical fiber channel 211 is connected to the second optical fiber channel 321, so as to connect the movable optical fiber 220 with the fixed optical fiber 330.

[0070] The male plug 200 further includes a second spring 250, which is located in the accommodating cavity 213. The second spring 250 is used to make the moving member 240 have a tendency to move in the direction where the movable member 320 is located. When the male plug 200 and the female plug 300 are plugged together, the moving member 240 and the fixing member 360 abut against each other. Under the action of external force, the moving member 240 moves in the plugging direction relative to the main body 210, thereby compressing the second spring 250. Then, when the male plug 200 and the female plug 300 are disconnected, the moving member 240 can move in the pulling-out direction under the action of the rebound force and return to the position before the docking.

[0071] It should be noted that when the male plug 200 and the female plug 300 are plugged in, the movable part 320 abuts against the main body 210 and the moving part 240 and the fixed part 360 at the same time, so that the movable part 320 and the moving part 240 move at the same time under the action of external force, and compress the first spring 350 and the second spring 250 respectively; and, at the same moment, the first sealing block 230 moves from the first optical fiber channel 211 to the first accommodating portion 212, and the second sealing block 340 moves from the second optical fiber channel 321 to the second accommodating portion 322.

[0072] In order to place the second spring 250 in the accommodating cavity 213, the accommodating cavity 213 is a through chamber, so that the second spring 250 can enter the accommodating cavity 213 from the end of the accommodating cavity 213 away from the female plug 300. In order to ensure that the accommodating cavity 213 is a sealed space during the use of the wet optical plug 100, the present embodiment further includes a first blocking member 290. After the second spring 250 is placed in the accommodating cavity 213, the first blocking member 290 is disposed on the main body 210 to block the accommodating cavity 213.

[0073] According to the above content, in order to prevent the first sealing block 230 from getting stuck during the movement, the male plug 200 also includes a connecting member 260, the two ends of which are movably connected to the first sealing block 230 and the moving member 240, respectively, and the connecting member 260 is located in the first accommodating portion 212. Figure 3 and Figure 6 Both ends of the connecting member 260 are connected to the first sealing block 230 and the moving member 240 through a rotating shaft, so that the connecting member 260 can rotate simultaneously during the movement, thereby driving the first sealing block 230 to move from the first optical fiber channel 211 to the first accommodating portion 212, and preventing the first sealing block 230 from getting stuck during the movement, ensuring the connection between the active optical fiber 220 and the fixed optical fiber 330, and completing the optical fiber transmission. It should be noted that in this embodiment, the structure of the connecting member 260 is a rod body.

[0074] Furthermore, in the present embodiment, the first sealing block 230 is provided with a first clamping portion 231, and the movable member 240 is provided with a second clamping portion 241; the two ends of the connecting member 260 are respectively provided with a first clamping groove 261 and a second clamping groove 262, and the first clamping portion 231 and the first clamping groove 261 are movably matched; the second clamping portion 241 and the second clamping groove 262 are movably matched.

[0075] Specifically, during the installation of the connector 260 and the first sealing block 230, the connector 260 and the first sealing block 230 can be connected together by using the first clamping portion 231 and the first clamping groove 261, and then the connector 260 is extended out of the first optical fiber channel 211. The connector 260 and the first sealing block 230 are continuously moved, and when the first sealing block 230 enters the first optical fiber channel 211, the connector 260 is moved from the first optical fiber channel 211 to the first accommodating portion 212. The connector 260 and the first sealing block 230 are continuously moved, and when the first sealing block 230 enters the first accommodating portion 212, part of the connector 260 enters the accommodating cavity 213, and the second clamping groove 262 is connected to the second clamping portion 241, thereby completing the installation of the first sealing block 230 and the connector 260.

[0076] According to the above arrangement, the movable member 240 includes a movable portion 242 and an abutting portion 243, and the movable portion 242 is detachably connected to the abutting portion 243; the movable portion 242 is provided with a second snap-in groove 262; wherein, when the male plug 200 and the female plug 300 are plugged in, the abutting member and the fixing member 360 abut against each other.

[0077] Specifically, the present embodiment provides a detachable abutment portion 243, so that after the first connecting rod enters the first accommodating portion 212 and the first sealing block 230 enters the first optical fiber channel 211, the front end face of the accommodating cavity 213 can be used to assist in completing the engagement of the second engaging groove 262 and the second engaging portion 241.

[0078] After the second clamping groove 262 and the second clamping portion 241 are clamped together, the abutting portion 243 is installed at the end of the moving portion 242, so that when the male plug 200 and the female plug 300 are plugged and matched, the abutting portion 243 can abut against the fixing member 360, thereby ensuring the sealing of the wet optical plug 100. Further, the female plug 300 also includes a fourth spring 370, which is located in the second accommodating portion 322. The fourth spring 370 is used to make the second sealing block 340 have a tendency to move from the second accommodating portion 322 to the second optical fiber channel 321. It should be noted that in this embodiment, when the second sealing block 340 blocks the second optical fiber channel 321, the fourth spring 370 abuts against the top surface of the second accommodating portion 322. During the process of removing the second sealing block 340, the second sealing block 340 moves from the second optical fiber channel 321 to the second accommodating portion 322, thereby compressing the fourth spring 370. When the male plug 200 and the female plug 300 need to be disconnected, the second sealing block 340 will move in the opposite direction under the action of the elastic force, that is, move from the second accommodating portion 322 to the second optical fiber channel 321, thereby re-blocking the second optical fiber channel 321 to prevent seawater and marine organisms from entering the second optical fiber channel 321 and affecting the transmission effect and service life of the optical fiber.

[0079] It should be noted that when installing the female plug 300, the second sealing block 240 needs to be placed in the second accommodating portion 322 through the through hole 325, and then the fourth spring 370 is placed, and the through hole 325 is blocked by the blocking member. According to the above content, the male plug 200 also includes a third spring 270, which is located in the first optical fiber channel 211, and the third spring 270 is used to make the active optical fiber 220 have a tendency to move toward the end of the first optical fiber channel 211. Specifically, when the first sealing block 230 blocks the first optical fiber channel 211, the third spring 270 is in a compressed state. After the first sealing block 230 moves out of the first optical fiber channel 211, the active optical fiber 220 will move to the end face of the first optical fiber channel 211 under the action of the rebound force, thereby connecting with the fixed optical fiber 330.

[0080] In this embodiment, the housing 310 is provided with a third optical fiber channel 312, the third optical fiber channel 312 is communicated with the second optical fiber channel 321, and at least a portion of the fixed optical fiber 330 is accommodated in the third optical fiber channel 312. The housing 310 is also connected to a mating portion having the third optical fiber channel 312, the axis of the third optical fiber channel 312 is parallel to the axis direction of the housing 310, and the axis of the second optical fiber channel 321 coincides with the axis of the third optical fiber channel 312.

[0081] The fixed optical fiber 330 includes a fixed optical fiber head, which is located in the second optical fiber channel 321 and abuts against the end of the third optical fiber channel 312. The fixed optical fiber head and the third optical fiber channel 312 extend into the second optical fiber channel 321 simultaneously, and the other part of the fixed optical fiber 330 is located in the third optical fiber channel 312, so that during installation, the optical fiber and the fixed optical fiber head can be connected together through the third optical fiber channel 312 to form the fixed optical fiber 330.

[0082] For further information, please refer to Fig.11 , Fig.11The present invention is a structural schematic diagram of the male plug 200 and the female plug 300 of the wet optical plug 100 provided by the present invention after docking at a second viewing angle; in order to ensure that the movable part 320 can abut against the main body 210 and the movable part 240 can abut against the fixed part 360, the male plug 200 also includes a positioning pin 280, and the positioning pin 280 is connected to the main body 210; the female plug 300 also includes a shell 310, the shell 310 is sleeved on the movable part 320 and connected to the fixed optical fiber 330; the shell 310 is provided with a guide groove 311 along the center of the female plug 300 in a direction away from the plug-in position of the male plug 200 and the female plug 300, and the guide groove 311 is plugged with the positioning pin 280 to ensure that when the male plug 200 and the female plug 300 are plugged and matched, the first optical fiber channel 211 is opposite to the second optical fiber channel 321, thereby ensuring that the first optical fiber channel 211 and the second optical fiber channel 321 can be connected, so that the movable optical fiber 220 is connected to the fixed optical fiber 330.

[0083] Furthermore, the male plug 200 further includes a shell, which is sleeved on the main body 210, and the shell and the main body 210 are spaced apart to form a first chamber, and the housing 310 and the movable member 320 in the female plug 300 are also spaced apart to form a second chamber, wherein the first chamber and the second chamber are filled with silicone oil. Both the male plug 200 and the female plug 300 are provided with oil sacs, and silicone oil is contained in the oil sacs. When the male plug 200 and the female plug 300 are working under the sea, the seawater compresses the oil sacs, so that the internal and external pressures of the male plug 200 and the female plug 300 are balanced.

[0084] In summary, the wet optical plug 100 is provided with a first sealing block 230 and a second sealing block 340 at the ends of the first optical fiber channel 211 and the second optical fiber channel 321, respectively, wherein the first sealing block 230 can block the first optical fiber channel 211, and the second sealing block 340 can block the second sealing channel, so as to form a sealed space before the male plug 200 and the female plug 300 are plugged in; when the male plug 200 and the female plug 300 are plugged in, the first optical fiber channel 211 and the fixed optical fiber 330 are connected, the boundary between the first optical fiber channel 211 and the second optical fiber channel 321 is blocked from the external environment, and the first sealing block 230 and the second sealing block 340 are moved out of the first optical fiber channel 211 and the second optical fiber channel 321, so as to connect the active optical fiber 220 and the fixed optical fiber 330. Therefore, the active optical fiber 220 and the fixed optical fiber 330 are in a sealed environment before and after plugging in, so as to avoid the influence of seawater, mud and sand, marine organisms and other factors on the transmission effect and service life of the optical fiber.
