[0053] The embodiment provides a wet type optical plug 100 which comprises a male plug 200 and a female plug 300, the male plug 200 comprises a main body 210, a movable optical fiber 220 and a first sealing block 230, the main body 210 is provided with a first optical fiber channel 211, the movable optical fiber 220 is located in the first optical fiber channel 211, and the first sealing block 230 is movably arranged at the end of the first optical fiber channel 211 and can block or move out of the first optical fiber channel 211; the female plug 300 comprises a shell 310, a movable part 320, a fixed optical fiber 330 and a second sealing block 340, the movable part 320 is arranged in the shell 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, 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 connected, the main body 210 and the movable part 320 abut, the first optical fiber channel 211 and the second optical fiber channel 321 are communicated, and the critical position of 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 move out of the first optical fiber channel 211 and the second optical fiber channel 321 respectively, and the movable optical fiber 220 and the fixed optical fiber 330 are connected.

[0054] Specifically, referring to Figure 5 , the side surface of the first sealing block 230 is closely combined 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 movable optical fiber 220 is located in the first optical fiber channel 211, that is, the movable optical fiber 220 is located in the closed space; similarly, the side surface of the second sealing block 340 is closely combined 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; so that the movable optical fiber 220 and the fixed optical fiber 330 are located in a sealed environment before the male plug 200 and the female plug 300 are connected, thereby avoiding the entry of seawater and marine organisms into the optical fiber channel and avoiding the influence on the transmission effect and the service life of the optical fiber caused by the connection of the optical fiber.

[0055] Please refer to Figure 8 , after the male plug 200 and the female plug 300 are connected, the first sealing block 230 moves out of the first optical fiber channel 211, 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 communicated; and the movable optical fiber 220 moves to the position of the first sealing block 230 when the first optical fiber channel 211 is blocked, so that the end of the fixed optical fiber 330 is exposed and connected with the movable optical fiber 220.

[0056] It should be noted that, in the process of docking, the main body 210 first extends into the shell 310, and the end of the shell 310 is provided with a slope extending away from the center line of the female plug 300, guiding the main body 210 into the shell 310. Then, the main body 210 and the movable part 320 abut together to block seawater and marine organisms from entering the optical fiber channel, and finally, 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 at the same time.

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

[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, to avoid the influence of seawater and marine organisms on the transmission effect and service life of the optical fiber before docking.

[0059] During docking, the main body 210 extends into the shell 310 and abuts against the movable part 320, so that the critical part of the main body 210 and the movable part 320 is sealed; continue to push the main body 210 in the plug-in direction, the main body 210 drives the movable part 320 to move in the plug-in 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; continue to push the main body 210 in 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, in the process of moving, the fixed optical fiber 330 extends relative to the movable part 320, so that the fixed optical fiber 330 is connected with the movable optical fiber 220.

[0060] Finally, after the movable optical fiber 220 is connected with 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 after being connected with the outside, thereby forming a closed space, so that the movable 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, 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 connector 300 further comprises a first spring 350, two ends of the first spring 350 being connected with the movable piece 320 and the shell 310 respectively, the shell 310 being sleeved on the first spring 350, the first spring 350 being used for making the movable piece 320 have a tendency to move towards the direction where the male connector 200 is located. When the male connector 200 and the female connector 300 are plugged together, the movable piece 320 and the main body 210 abut, under the action of an external force, the movable piece 320 moves relative to the shell 310 towards the plugging direction, so as to compress the first spring 350, and then when the male connector 200 and the female connector 300 are disconnected, the movable piece 320 can move towards the pulling-off direction under the action of the elastic force of the first spring 350, and return to the position before the abutment.

[0062] Understandably, the inner wall of the shell 310 is provided with a groove for clamping the movable piece 320, so as to limit the moving distance of the movable piece 320 and prevent the movable piece 320 from sliding out.

[0063] Further, the main body 210 is provided with a first accommodating portion 212, the first accommodating portion 212 being in communication with the first optical fiber channel 211; the movable piece 320 is provided with a second accommodating portion 322, the second accommodating portion 322 being in communication with the second optical fiber channel 321; the first accommodating portion 212 is used for accommodating the first sealing block 230 removed from the first optical fiber channel 211 when the male connector 200 and the female connector 300 are plugged together; the first accommodating portion 212 is used for accommodating the second sealing block 340 removed from the second optical fiber channel 321 when the male connector 200 and the female connector 300 are plugged together. Specifically, after the male connector 200 and the female connector 300 are abutted, the first sealing block 230 and the second sealing block 340 need to be removed, so that the movable optical fiber 220 is connected with the fixed optical fiber 330, 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 open and in communication, and the movable optical fiber 220 and the fixed optical fiber 330 are not shielded by the first sealing block 230 and the second sealing block 340, and then the movable optical fiber 220 and the fixed optical fiber 330 are connected.

[0064] According to the above arrangement, please refer to Figures 1-9The 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 stopper 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 stopper 340 to move from the second optical fiber channel 321 to the second accommodating portion 322. Specifically, in the embodiment, the extension direction of the first guide surface 221 and the extension direction of the second guide surface 331 can form an included 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 stopper 340 is provided with a fourth guide surface matched with the second guide surface 331, the extension direction of the fourth guide surface and the extension direction of the second guide surface 331 are parallel, and the second guide surface 331 and the fourth guide surface are in contact during the movement of the second sealing stopper 340 out of the second optical fiber channel 321.

[0066] Further, referring to Figure 5 and Figure 8 , the second sealing stopper 340 is provided with a boss 341, the second accommodating 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 stopper 340 and guide the second sealing stopper 340 to move to the second accommodating portion 322. Specifically, the boss 341 is arranged above the side of the second sealing stopper 340 close to the end of the second optical fiber channel 321, the boss 341 abuts against the third guide surface, limits the displacement distance of the second sealing stopper 340, and prevents the second sealing stopper 340 from being separated. In the embodiment, the extension direction of the third guide surface 324 and the extension direction of the second guide surface form an included angle, and the included angle is less than 90 degrees, so that the second sealing stopper 340 can move from the second optical fiber channel 321 to the second accommodating 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, the movable member 320 further comprises a through hole 325, and the through hole 325 is in communication with the second optical fiber channel 321; the through hole 325 is used to pass the second sealing stopper 340 when the female plug 300 is installed; the female plug 300 further comprises a blocking member matched with the through hole 325, and the blocking member 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 piece to seal the through hole 325. When installing the sealing piece, glue can be applied to the gap between the inner wall of the through hole 325 and the sealing piece, so that the sealing piece 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 cavity 213, which is connected to the first accommodating portion 212; the moving part 240 is movably arranged in the accommodating cavity 213, and the moving part 240 is connected to the first sealing block 230; the female plug 300 also includes a fixing part 360, which is connected to the shell 310, and the moving part 320 is provided with a through hole 323 that slides 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 removal direction, while the movable member 320 moves in the insertion direction, thereby causing the through hole 323 to move relative to the fixed member 360, causing the fixed member 360 to extend out of the through hole 323, thereby enabling the movable member 240 to drive the first sealing block 230 to move to the first optical fiber channel 211 and then to the first accommodating portion 212, thereby connecting the first optical fiber channel 211 and the second optical fiber channel 321, thereby connecting the movable optical fiber 220 to the fixed optical fiber 330.

[0070] The male plug 200 also includes a second spring 250 located within the accommodating cavity 213. The second spring 250 is configured to bias the movable member 240 toward the location of the movable member 320. When the male plug 200 and the female plug 300 are mated, the movable member 240 abuts against the fixed member 360. Under the action of an external force, the movable member 240 moves relative to the main body 210 in the mating direction, thereby compressing the second spring 250. Consequently, when the male plug 200 and the female plug 300 are disconnected, the movable member 240 is able to move in the disconnection direction due to the rebound force, returning to its pre-mated position.

[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, the moving part 240 and the fixed part 360 at the same time, so that under the action of external force, the movable part 320 and the moving part 240 move at the same time 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] To accommodate the second spring 250 within the accommodating chamber 213, the accommodating chamber 213 is a through-hole chamber, allowing the second spring 250 to enter the accommodating chamber 213 from the end of the accommodating chamber 213 away from the female plug 300. To ensure that the accommodating chamber 213 is a sealed space during use of the wet-type optical plug 100, this embodiment further includes a first sealing member 290. After the second spring 250 is placed within the accommodating chamber 213, the first sealing member 290 is mounted on the main body 210 to seal the accommodating chamber 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 further 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 movable member 240 via a rotating shaft, so that the connecting member 260 can rotate simultaneously during movement, thereby driving the first sealing block 230 from the first optical fiber channel 211 to the first accommodating portion 212 and preventing the first sealing block 230 from getting stuck during movement, thereby ensuring the connection between the movable optical fiber 220 and the fixed optical fiber 330 and completing optical fiber transmission. It should be noted that in this embodiment, the connecting member 260 is structured as a rod.

[0074] Furthermore, in this 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 first be connected together using the first clamping portion 231 and the first clamping groove 261, and then the connector 260 can be extended out of the first fiber channel 211. The connector 260 and the first sealing block 230 are then moved. When the first sealing block 230 enters the first fiber channel 211, the connector 260 is moved from the first fiber channel 211 to the first accommodating portion 212. The connector 260 and the first sealing block 230 are then moved. When the first sealing block 230 enters the first accommodating portion 212, a portion 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-fitting 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, this embodiment provides a detachable abutment portion 243, so that the staff can enter the first accommodating portion 212 after the first connecting rod and the first sealing block 230 enters the first optical fiber channel 211, and then the front end face of the accommodating cavity 213 can be used to assist in completing the clamping of the second clamping groove 262 and the second clamping portion 241.

[0078] After the second engaging groove 262 and the second engaging portion 241 are engaged, the abutting portion 243 is mounted on the end of the movable portion 242. This allows the abutting portion 243 to abut against the fixing member 360 when the male plug 200 and the female plug 300 are mated, thereby ensuring the sealing of the wet-type optical plug 100. Furthermore, the female plug 300 includes a fourth spring 370, which is located within the second accommodating portion 322. The fourth spring 370 is used to force the second sealing block 340 from the second accommodating portion 322 toward 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 must first be placed through the through-hole 325 into the second accommodating portion 322, followed by the placement of the fourth spring 370 and the use of a sealing member to seal the through-hole 325. Based on the above, the male plug 200 also includes a third spring 270, which is positioned within the first fiber channel 211. The third spring 270 is used to force the active optical fiber 220 toward the end of the first fiber channel 211. Specifically, when the first sealing block 230 seals the first fiber channel 211, the third spring 270 is compressed. After the first sealing block 230 is removed from the first fiber channel 211, the active optical fiber 220, under the action of the rebound force, moves to the end face of the first fiber channel 211, thereby connecting with the fixed optical fiber 330.

[0080] In this embodiment, the housing 310 is provided with a third optical fiber channel 312, which communicates with the second optical fiber channel 321. At least a portion of the fixed optical fiber 330 is accommodated within the third optical fiber channel 312. The housing 310 is also connected to a mating portion defining the third optical fiber channel 312. The axis of the third optical fiber channel 312 is parallel to the axis 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 parts of the fixed optical fiber 330 are 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 Figure 11 , Figure 11This is a schematic structural diagram of the male plug 200 and the female plug 300 of the wet-type optical plug 100 provided by the present invention after docking from a second perspective; to ensure that the movable member 320 can abut against the main body 210 and the movable member 240 can abut against the fixed member 360, the male plug 200 further includes a positioning pin 280, which is connected to the main body 210; the female plug 300 further includes a housing 310, which is sleeved on the movable member 320 and connected to the fixed optical fiber 330; the housing 310 has a guide groove 311 along the center of the female plug 300, first away from the plug-in connection point of the male plug 200 and the female plug 300, and the guide groove 311 is plugged into and engaged with the positioning pin 280 to ensure that when the male plug 200 and the female plug 300 are plugged into and engaged, the first optical fiber channel 211 is aligned with the second optical fiber channel 321, thereby ensuring that the first optical fiber channel 211 and the second optical fiber channel 321 are connected, so that the movable optical fiber 220 is connected to the fixed optical fiber 330.

[0083] Furthermore, the male plug 200 includes a housing that fits over the main body 210, with the housing and main body 210 spaced apart to form a first chamber. The housing 310 and movable member 320 in the female plug 300 are also spaced apart to form a second chamber. Both the first and second chambers are filled with silicone oil. Both the male and female plugs 200 and 300 are equipped with oil sacs containing silicone oil. When the male and female plugs 200 and 300 are operating underwater, seawater compresses the oil sacs, thereby balancing the internal and external pressures of the male and female plugs 200 and 300.

[0084] In summary, the wet-type optical plug 100 provides a first sealing block 230 and a second sealing block 340 at the ends of the first fiber channel 211 and the second fiber channel 321, respectively. The first sealing block 230 can block the first fiber channel 211, and the second sealing block 340 can block the second sealing block, thereby forming 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 fiber channel 211 and the fixed fiber 330 are connected, and the boundary between the first fiber channel 211 and the second fiber channel 321 is blocked from the external environment. The first sealing block 230 and the second sealing block 340 are removed from the first fiber channel 211 and the second fiber channel 321, thereby connecting the active fiber 220 and the fixed fiber 330. As a result, the active fiber 220 and the fixed fiber 330 are in a sealed environment before and after plugging in, preventing factors such as seawater, sediment, and marine life from affecting the transmission performance and service life of the optical fibers.

[0085] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
