[0023] Embodiment Reference Figures 1-7 , a rotary wet-mateable fiber optic hybrid connector, comprising: a first connector 100, including a first outer shell 101, a first inner shell, and a first plug 103; the first inner shell has the ability to expand and contract deforming, one end of the first inner shell is fixed on the first outer shell 101, the other end of the first inner shell is slidably disposed in the first outer shell 101 and is provided with a first connection port; one end of the first plug 103 is disposed on the first inner shell, the other end of the first plug 103 is used to seal the first connection port and is provided with a boss 1031; a second connector 200, including a second outer shell 201, a second inner shell, a second plug 203, and an elastic telescopic assembly; the second outer shell 201 is used for pluggable connection with the first outer shell 101; the second inner shell is disposed in the second outer shell 201 and the second inner shell is provided with a second connection port and a seal 205 located at the second connection port, the seal 205 can be sleeved on the outer sides of the second plug 203 and the first inner shell and seal; both ends of the elastic telescopic assembly are respectively connected to the second inner shell and the second plug 203; the end of the second plug 203 away from the elastic telescopic assembly is provided with a clamping groove 2031 for cooperating with the boss 1031.

[0024] When the first connector 100 and the second connector 200 are connected underwater, the second outer shell 201 is inserted into the first outer shell 101, the boss 1031 on the first plug 103 is clamped in the clamping groove 2031 of the second plug 203. At this time, the liquid between the first plug 103 and the second plug 203 is displaced, and the first plug 103 and the second plug 203 are axially abutted and sealed; the inner diameter of the first outer shell 101 is greater than the outer diameter of the second outer shell 201. As the second outer shell 201 moves in the first outer shell 101, the liquid between the first plug 103 and the second plug 203 will finally drain out from the gap between the first outer shell 101 and the second outer shell 201.

[0025] The first plug 103 presses the second plug 203 to move towards the elastic telescopic component side, and the seal 205 gradually transitions from the outer wall of the second plug 203 to the outer wall of the first inner shell. When the second outer shell 201 presses the first inner shell to slide relative to the first outer shell 101, the first plug 103 disengages from the first connection port and moves into the second inner shell along with the second plug 203. During this process, the seal between the seal 205 and the outer wall of the first inner shell can prevent external liquid from entering the first inner shell or the second inner shell, resulting in a better sealing effect for the rotary wet-mateable fiber optic hybrid connector.

[0026] When the elastic telescopic component is not deformed, the elastic telescopic component can drive the second plug 203 to be clamped at the position of the second connection port. At this time, the seal 205 is sleeved on the outer side of the second plug 203 to prevent liquid from entering the internal cavity of the second inner shell from the second connection port. When the first plug 103 presses the second plug 203 to axially move to the inner side of the second inner shell, the elastic telescopic component is compressed; when the second connector 200 disengages from the first connector 100, the elastic telescopic component will return to its original length and drive the second plug 203 to be re-clamped at the second connection port.

[0027] The inner side wall of the first outer shell 101 is provided with a guiding groove 1011 extending along the axis of the first outer shell 101, and the outer side wall of the second outer shell 201 is provided with a guiding block 2011 that cooperates with the guiding groove 1011. When inserting the second outer shell 201 into the first outer shell 101, the guiding block 2011 needs to be inserted into the guiding groove 1011 first so that the second plug 203 can be aligned with the first plug 103. The cooperation between the guiding block 2011 and the guiding groove 1011 can prevent the second outer shell 201 from rotating circumferentially relative to the first outer shell 101.

[0028] The outer side wall of the second outer shell 201 is provided with a limiting block 2012, and the outer diameter of the limiting block 2012 is larger than the inner diameter of the first outer shell 101. The limiting block 2012 is used for axially positioning the first outer shell 101 and the second outer shell 201. When the second outer shell 201 is inserted into the first outer shell 101 and the axial end of the first outer shell 101 abuts against the limiting block 2012, the axial positions of the first outer shell 101 and the second outer shell 201 reach the preset positions at this time.

[0029] The outer side walls of the first outer shell 101 and the second outer shell 201 can be provided with a clamping structure (not shown in the figure). After the second outer shell 201 is inserted into the specified position in the first outer shell 101, the second outer shell 201 can be connected to the first outer shell 101 through the clamping structure to prevent the second outer shell 201 from disengaging from the first outer shell 101 under the action of the elastic telescopic component.

[0030] As an alternative implementation, the first joint 100 further includes a first sealing ring 104; the axial end face of the first plug 103 near the boss 1031 is used to abut against the axial end face of the second plug 203, and a first sealing ring 104 is provided at the connection between the first plug 103 and the boss 1031.

[0031] The boss 1031 can be in the shape of a frustum of a cone, and the clamping groove 2031 can be a tapered groove. The diameter of the end face of the boss 1031 away from the first plug 103 is smaller than the opening diameter of the clamping groove 2031, so that when the first plug 103 and the second plug 203 are butted, the boss 1031 can be inserted into the clamping groove 2031 more smoothly. The first sealing ring 104 can be an O-ring. The outer circle of the first sealing ring 104 is located outside the outer circle of the boss 1031. When the boss 1031 is inserted into the clamping groove 2031, the first sealing ring 104 abuts against the side wall of the clamping groove 2031, and the first sealing ring 104 deforms and fits tightly against the side wall of the clamping groove 2031, preventing the liquid remaining at the connection between the first plug 103 and the second plug 203 from entering the interior of the second capsule 2021, so that the axial end faces of the first plug 103 and the second plug 203 are sealed well.

[0032] As an alternative implementation, the first joint 100 further includes a second sealing ring 105; the first plug 103 is provided with a connection groove at the first connection port; the second sealing ring 105 is arranged on the first plug 103, and the end face of the second sealing ring 105 near the boss 1031 is used to abut against the axial end face of the second plug 203; the outer side wall of the first plug 103 and the outer side wall of the second sealing ring 105 can both fit against the side wall of the connection groove.

[0033] The cross-section of the second sealing ring 105 can be in the shape of an L. The first plug 103 can be provided with a clamping groove that cooperates with the second sealing ring 105. After the second sealing ring 105 is clamped in the clamping groove, two sides of the second sealing ring 105 are exposed on the outside. One side is used to abut against the side wall of the connection groove, and the other side is used to abut against the second plug 203 and the inner diameter of this side can be greater than or equal to the outer circle of the first sealing ring 104. When the first plug 103 cooperates with the connection groove, the second sealing ring 105 seals the first connection port. When the boss 1031 of the first plug 103 is inserted into the clamping groove 2031 of the second plug 203, the first sealing ring 104 abuts against the side wall of the clamping groove 2031 to form a first seal, and the second sealing ring 105 abuts against the second plug 203 to form a second seal, so that the axial end faces of the first plug 103 and the second plug 203 are sealed well.

[0034] As an alternative implementation, the connection groove is a tapered groove and the aperture of the connection groove on the side away from the second joint 200 is smaller than the aperture of the connection groove on the side close to the second joint 200.

[0035] The initial elastic force of the first spring 109 presses against the mounting cylinder 1024, causing the first plug 103 to tightly adhere to the conical surface of the connection groove for sealing, preventing water from entering the interior of the first inner shell through the first connection port.

[0036] The conical structure has a guiding property. When the first plug 103 axially moves from the outside of the first inner shell towards the connection groove, the first plug 103 can automatically calibrate the position between the first plug 103 and the connection groove through the conical surface, making the assembly more convenient.

[0037] As an alternative implementation, the cross-section of the seal 205 is in a "W" shape. There are two sealing lips at the parts of the seal 205 that are used to contact the second plug 203 or the first inner shell. Thus, two sealing lines can be provided. When one seal fails due to wear or pressure change, the other sealing lip can still maintain the sealing effect, significantly reducing the leakage risk.

[0038] The seal 205 has a two-way sealing effect. The outer sealing lip can prevent water from entering the internal cavity of the second inner shell, and the inner sealing lip can prevent the insulating oil in the second inner shell from leaking, thus achieving two-way protection.

[0039] In addition, the two sealing lips can disperse the contact pressure of the seal 205, reduce the wear of a single sealing lip, and extend the overall service life.

[0040] As an alternative implementation, insulating oil is filled in both the internal cavity of the first inner shell and the internal cavity of the second inner shell.

[0041] The breakdown voltage of the insulating oil is higher than that of air, which can greatly improve the insulation ability inside the connector. For example, the dielectric strength of mineral oil can reach 30 - 40 kV / mm, while that of air is only 3 kV / mm, which can effectively suppress the risk of arc discharge or leakage under high-voltage environments. After the insulating oil fills the gap between the first inner shell and the second inner shell, the corona discharge phenomenon in the air gap can be eliminated, avoiding the deterioration of the insulating material due to long-term discharge.

[0042] In addition, a first pin assembly 106 is provided in the first inner shell, and a second pin assembly 206 is provided in the second inner shell. When the first pin assembly 106 is connected to the second pin assembly 206, the insulating oil has a lubricating effect on the first pin assembly 106 and the second pin assembly 206, reducing the friction force between the pin and the socket by 30% - 50% and extending the plugging and unplugging service life.

[0043] As an alternative embodiment, the first inner shell includes a first base 1021, a first capsule 1022, a sliding member 1023, and a mounting cylinder 1024; the first base 1021 is disposed on the first outer shell 101; the sliding member 1023 is slidably disposed on the first outer shell 101, the mounting cylinder 1024 is disposed on the sliding member 1023, an opening of the mounting cylinder 1024 forms a first connection port, and an outer side surface of the mounting cylinder 1024 can be wrapped by a seal 205; one end of the first capsule 1022 is connected to the first base 1021, and the other end of the first capsule 1022 is connected to the mounting cylinder 1024.

[0044] When the second outer shell 201 is inserted into the first outer shell 101, the seal 205 gradually transitions from the second plug 203 to the mounting cylinder 1024, and an axial end of the second outer shell 201 will eventually abut against the sliding member 1023 and drive the sliding member 1023 to axially move along the first outer shell 101. The first capsule 1022 can be made of a rubber material, so that the first capsule 1022 has a large deformation ability.

[0045] The first joint 100 may include a guide rod 107, a first sleeve 108, and a first spring 109; the first sleeve 108 is disposed on the first base 1021, one end of the guide rod 107 is connected to the mounting cylinder 1024, and the other end of the guide rod 107 is sleeved inside the first sleeve 108; the first spring 109 is sleeved outside the guide rod 107, and two ends of the first spring 109 are respectively connected to the first base 1021 and the mounting cylinder 1024. When the second outer shell 201 abuts against the sliding member 1023 and axially moves toward the first base 1021, the mounting cylinder 1024 can compress the first spring 109 and deform; when the second outer shell 201 disengages from the first outer shell 101, the first spring 109 restores deformation and drives the mounting cylinder 1024 to move toward a side away from the first base 1021.

[0046] As an alternative embodiment, a cross section of the first capsule 1022 is in a wavy curve shape. A cavity surrounded by the first capsule 1022, the first base 1021, the mounting cylinder 1024, and the first plug 103 is filled with insulating oil. When the sliding member 1023 drives the first capsule 1022 to move through the mounting cylinder 1024, the volume of the insulating oil in the first capsule 1022 will change. The wavy curve-shaped first capsule 1022 enables the first capsule 1022 to achieve large-scale expansion and contraction both axially and radially. The wavy first capsule 1022 can guide the insulating oil to form a laminar flow and reduce the flow resistance.

[0047] The second inner shell may include a second capsule 2021 and a second base 2022; the second base 2022 is disposed on the first outer shell 101; one end of the second capsule 2021 is connected to the second base 2022, the other end of the second capsule 2021 is connected to the second outer shell 201 and is provided with a second connection port; an elastic telescopic assembly is disposed on the second base 2022.

[0048] As an alternative implementation, the elastic expansion and contraction component includes a second sleeve 2041 and a second spring 2042; the second sleeve 2041 is disposed on the second inner shell; one end of the second plug 203 away from the second connection port and the second spring 2042 are both located within the second sleeve 2041, and two ends of the second spring 2042 are respectively connected to the second sleeve 2041 and the second plug 203.

[0049] Specifically, the second sleeve 2041 may be disposed on the second base 2022; The first plug 103 is rotatably connected to the first inner shell and cannot axially move relative to the first inner shell. When the second outer shell 201 is inserted into the first outer shell 101, the first plug 103 gradually presses the second plug 203 into the interior of the second inner shell. At this time, the second plug 203 axially moves along the second sleeve 2041 and compresses the second spring 2042; when the second outer shell 201 is pulled out of the first outer shell 101, the second spring 2042 returns to its original length and drives the second plug 203 to cooperate with the second connection port again.

[0050] As an alternative implementation, the first connector 100 further includes two groups of first pin assemblies 106 disposed on the first inner shell; the second connector 200 further includes two groups of second pin assemblies 206 disposed on the second inner shell, and the second pin assemblies 206 are used to connect with the first pin assemblies 106; the cross sections of the first plug 103 and the second plug 203 are both in the shape of an "8". The second sleeve 2041 is provided with a guide hole 20411, and the second plug 203 is provided with a guide member 2032 that cooperates with the guide hole 20411. When the second plug 203 axially moves along the second sleeve 2041, the guide member 2032 moving along the guide hole 20411 can drive the second plug 203 to rotate relative to the second sleeve 2041, so that the second plug 203 can move in the gap between the two groups of second pin assemblies 206.

[0051] Before the first connector 100 and the second connector 200 are connected, the two end faces of the first plug 103 respectively correspond to a set of first pin assemblies 106, and the two end faces of the second plug 203 respectively correspond to a set of second pin assemblies 206; when the first connector 100 and the second connector 200 are plugged together, the first plug 103 and the second plug 203 are engaged with each other, and the "8" shape restricts the circumferential rotation of the first plug 103 and the second plug 203; when the second plug 203 moves along the second sleeve 2041, the guide member 2032 drives the second plug 203 to rotate relative to the second sleeve 2041, and at the same time the first plug 103 rotates with the second plug 203, and the rotation angle can be 90 degrees, so that the rotated second plug 203 is offset from the second pin assembly 206, and the first plug 103 is offset from the first pin assembly 106. At this time, the first pin assembly 106 and the second pin assembly 206 can be axially butted.

[0052] Working principle of the rotary wet-mateable electro-optical composite connector: When the first connector 100 and the second connector 200 are connected underwater, the second housing 201 is inserted into the first housing 101, and the boss 1031 on the first plug 103 is engaged in the engagement groove 2031 of the second plug 203. At this time, the liquid between the first plug 103 and the second plug 203 is displaced, the first plug 103 and the second plug 203 are axially abutted, a first sealing ring 104 is provided at the connection between the first plug 103 and the boss 1031, and the first plug 103 is further provided with a second sealing ring 105 with an L-shaped cross section. The first sealing ring 104 abuts against the side wall of the engagement groove 2031 to form a first seal, and the second sealing ring 105 abuts against the second plug 203 to form a second seal; the inner diameter of the first housing 101 is larger than the outer diameter of the second housing 201. As the second housing 201 moves in the first housing 101, the liquid between the first plug 103 and the second plug 203 will finally drain out from the gap between the first housing 101 and the second housing 201.

[0053] The first plug 103 presses the second plug 203 into the interior of the second inner housing. The second plug 203 will axially move along the second sleeve 2041 and compress the second spring 2042. At the same time, the guide member 2032 moving along the guide hole 20411 can drive the second plug 203 to rotate relative to the second sleeve 2041. Since the first plug 103 and the second plug 203 are engaged with each other, the first plug 103 rotates relative to the first inner housing. The rotation angles of the first plug 103 and the second plug 203 are 90 degrees. At this time, the second plug 203 is offset from the second pin assembly 206, and the first plug 103 is offset from the first pin assembly 106. The second pin assembly 206 axially moves and finally docks with the first pin assembly 106. When the second outer housing 201 presses the first inner housing to slide relative to the first outer housing 101, the first inner housing presses the first spring 109 to deform. The first plug 103 disengages from the first connection port and moves into the interior of the second inner housing with the second plug 203. The seal 205 gradually transitions from the outer wall of the second plug 203 to the outer wall of the first inner housing to form a seal. During this process, the seal 205 can prevent liquid from entering the first inner housing or the second inner housing, resulting in a better sealing effect of the rotary wet-mateable optical-electrical composite connector.

[0054] When the second connector 200 is pulled out from the first connector 100, the first pin assembly 106 and the second pin assembly 206 are disengaged from each other. The first spring 109 will drive the first inner housing to move towards the second connector 200 side. Finally, the first connection port is resealed with the first plug 103. The second spring 2042 will drive the second plug 203 to move towards the second connection port. At the same time, under the cooperation of the guide member 2032 and the guide hole 20411, the first plug 103 and the second plug 203 rotate along the axis of the second plug 203. Finally, the second plug 203 is resealed with the second connection port.

Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
