[0032] Example

[0033] refer to Figure 1-Figure 7 A rotary wet-pluggable optoelectronic composite connector includes: a first connector 100, comprising a first outer shell 101, a first inner shell, and a first plug 103; the first inner shell is capable of telescopic deformation, one end of the first inner shell is fixed to the first outer shell 101, the other end of the first inner shell is slidably mounted on the first outer shell 101 and is provided with a first connection port; one end of the first plug 103 is mounted 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;

[0034] The second connector 200 includes a second outer shell 201, a second inner shell, a second plug 203 and an elastic telescopic component; the second outer shell 201 is used for plugging and unplugging connection with the first outer shell 101; the second inner shell is arranged 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, and the seal 205 can be mounted on the outside of the second plug 203 and the first inner shell and seal; the two ends of the elastic telescopic component 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 component is provided with a snap-in groove 2031 that cooperates with the boss 1031.

[0035] When the first connector 100 and the second connector 200 are connected underwater, the second shell 201 is inserted into the first shell 101, and the boss 1031 on the first plug 103 is engaged in the engaging groove 2031 of the second plug 203. At this time, the liquid between the first plug 103 and the second plug 203 is discharged, and the first plug 103 and the second plug 203 are axially abutted and sealed; the inner diameter of the first shell 101 is larger than the outer diameter of the second shell 201. As the second shell 201 moves in the first shell 101, the liquid between the first plug 103 and the second plug 203 will eventually be discharged from the gap between the first shell 101 and the second shell 201.

[0036] The first plug 103 compresses the second plug 203 to move toward the side of the elastic telescopic component, 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 compresses the first inner shell to slide relative to the first outer shell 101, the first plug 103 detaches from the first connection port and moves with the second plug 203 to the inside of the second inner shell. 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, so that the sealing effect of the rotary wet-plug optoelectronic composite connector is better.

[0037] When the elastic expansion assembly is not deformed, it can drive the second plug 203 to engage the second connection port. At this point, the seal 205 is positioned outside the second plug 203 to prevent liquid from entering the internal cavity of the second inner shell through the second connection port. When the first plug 103 compresses the second plug 203, axially moving it toward the inside of the second inner shell, the elastic expansion assembly is compressed. When the second connector 200 is detached from the first connector 100, the elastic expansion assembly returns to its original length and drives the second plug 203 to reengage the second connection port.

[0038] The inner sidewall of the first housing 101 is provided with a guide groove 1011 extending axially along the first housing 101. The outer sidewall of the second housing 201 is provided with a guide block 2011 that mates with the guide groove 1011. When inserting the second housing 201 into the first housing 101, the guide block 2011 must first be inserted into the guide groove 1011 so that the second plug 203 is aligned with the first plug 103. The engagement of the guide block 2011 with the guide groove 1011 prevents the second housing 201 from rotating circumferentially relative to the first housing 101.

[0039] A limit block 2012 is provided on the outer wall of the second shell 201. The outer diameter of the limit block 2012 is larger than the inner diameter of the first shell 101. The limit block 2012 is used to axially position the first shell 101 and the second shell 201. When the second shell 201 is inserted into the first shell 101 and the axial end of the first shell 101 abuts against the limit block 2012, the axial positions of the first shell 101 and the second shell 201 reach the preset positions.

[0040] The outer side walls of the first shell 101 and the second shell 201 can be provided with a snap-fit ​​structure (not shown in the figure). When the second shell 201 is inserted into the designated position in the first shell 101, the second shell 201 can be connected to the first shell 101 through the snap-fit ​​structure to prevent the second shell 201 from separating from the first shell 101 under the action of the elastic telescopic component.

[0041] As an optional embodiment, the first joint 100 also includes a first sealing ring 104; the axial end surface of the first plug 103 close to the boss 1031 is used to abut the axial end surface 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.

[0042] The boss 1031 may be truncated, while the engaging groove 2031 may be a tapered groove. The diameter of the end face of the boss 1031 facing away from the first plug 103 is smaller than the opening diameter of the engaging groove 2031. This allows the boss 1031 to be smoothly inserted into the engaging groove 2031 when the first plug 103 and the second plug 203 are mated. The first sealing ring 104 may be an O-ring. The outer diameter of the first sealing ring 104 is located outside the outer diameter of the boss 1031. When the boss 1031 is inserted into the engaging groove 2031, the first sealing ring 104 abuts against the sidewalls of the engaging groove 2031, deforming and clinging to the sidewalls of the engaging groove 2031. This prevents residual liquid at the connection between the first plug 103 and the second plug 203 from entering the interior of the second capsule 2021, thereby ensuring a good seal between the axial end faces of the first plug 103 and the second plug 203.

[0043] As an optional embodiment, the first joint 100 also includes a second sealing ring 105; the first plug 103 is provided with a connecting groove located at the first connecting port; the second sealing ring 105 is arranged on the first plug 103, and the end face of the second sealing ring 105 close to the boss 1031 is used to abut 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 the side wall of the connecting groove.

[0044] The second sealing ring 105 can have an L-shaped cross-section, and the first plug 103 can be provided with a slot that mates with the second sealing ring 105. After the second sealing ring 105 is engaged in the slot, two side surfaces of the second sealing ring 105 are exposed to the outside: one side surface is used to abut the side wall of the connecting groove, and the other side surface is used to abut the second plug 203. The inner diameter of this side surface can be greater than or equal to the outer diameter of the first sealing ring 104. When the first plug 103 is engaged with the connecting groove, the second sealing ring 105 seals the first connecting port. When the boss 1031 of the first plug 103 is inserted into the engaging slot 2031 of the second plug 203, the first sealing ring 104 abuts the side wall of the engaging slot 2031 to form a primary seal, and the second sealing ring 105 abuts the second plug 203 to form a secondary seal, thereby effectively sealing the axial end surfaces of the first plug 103 and the second plug 203.

[0045] As an optional embodiment, the connecting groove is a tapered groove, and the aperture of the connecting groove on the side away from the second joint 200 is smaller than the aperture of the connecting groove on the side close to the second joint 200 .

[0046] The initial elastic force of the first spring 109 pushes against the installation cylinder 1024, so that the first plug 103 and the conical surface of the connecting groove are tightly sealed, preventing water from entering the interior of the first inner shell from the first connecting port.

[0047] The conical structure has a guiding property. When the first plug 103 moves axially from the outside of the first inner shell to the connecting groove, the first plug 103 can automatically calibrate the position between the first plug 103 and the connecting groove through the conical surface, which makes assembly more convenient.

[0048] As an optional embodiment, the cross-section of the seal 205 is W-shaped. The seal 205 has two sealing lips where it contacts the second plug 203 or the first inner shell, thereby providing two sealing lines. If one seal fails due to wear or pressure changes, the other sealing lip can still maintain the sealing effect, significantly reducing the risk of leakage.

[0049] The seal 205 has a bidirectional sealing effect. The outer sealing lip can prevent water from entering the inner cavity of the second inner shell, and the inner sealing lip can prevent the insulating oil in the second inner shell from leaking, thereby achieving bidirectional protection.

[0050] In addition, the two sealing lips can distribute the contact pressure of the seal 205, reduce the wear of a single sealing lip, and extend the overall life.

[0051] As an optional embodiment, the inner cavity of the first inner shell and the inner cavity of the second inner shell are both filled with insulating oil.

[0052] Insulating oil has a higher breakdown voltage than air, significantly improving the insulation capability within the connector. For example, mineral oil has a dielectric strength of 30-40 kV / mm, compared to just 3 kV / mm for air. This effectively mitigates arcing and leakage risks in high-voltage environments. Filling the gap between the first and second inner shells with insulating oil eliminates corona discharge in the air gap, preventing long-term degradation of the insulation material due to discharge.

[0053] 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 and the second pin assembly 206 are connected, the insulating oil lubricates the first pin assembly 106 and the second pin assembly 206, reducing the friction between the pin and the socket by 30%-50%, thereby extending the plug-in life.

[0054] As an optional embodiment, the first inner shell includes a first base 1021, a first capsule 1022, a sliding member 1023 and an installation tube 1024; the first base 1021 is arranged on the first outer shell 101; the sliding member 1023 is slidably arranged on the first outer shell 101, and the installation tube 1024 is arranged on the sliding member 1023, and the opening of the installation tube 1024 forms a first connection port, and the outer side surface of the installation tube 1024 can be wrapped by the sealing member 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 installation tube 1024.

[0055] When the second housing 201 is inserted into the first housing 101, the sealing member 205 gradually transitions from the second plug 203 to the mounting cylinder 1024. The axial end of the second housing 201 eventually abuts against the sliding member 1023 and drives the sliding member 1023 to move axially along the first housing 101. The first capsule 1022 can be made of a rubber material, so that the first capsule 1022 has a large deformation capacity.

[0056] The first joint 100 may include a guide rod 107, a first sleeve 108, and a first spring 109. The first sleeve 108 is mounted on the first base 1021. One end of the guide rod 107 is connected to the mounting sleeve 1024, and the other end of the guide rod 107 is sleeved within the first sleeve 108. The first spring 109 is sleeved outside the guide rod 107, with both ends of the first spring 109 connected to the first base 1021 and the mounting sleeve 1024, respectively. When the second housing 201 abuts the sliding member 1023 and moves axially toward the first base 1021, the mounting sleeve 1024 compresses the first spring 109 and deforms it. When the second housing 201 separates from the first housing 101, the first spring 109 recovers its deformation and drives the mounting sleeve 1024 to move away from the first base 1021.

[0057] As an optional embodiment, the cross-section of the first capsule 1022 is wavy. The cavity enclosed by the first capsule 1022, the first base 1021, the mounting tube 1024, and the first plug 103 is filled with insulating oil. When the sliding member 1023 moves the first capsule 1022 via the mounting tube 1024, the volume of the insulating oil within the first capsule 1022 changes. The wavy shape of the first capsule 1022 enables a wide range of expansion and contraction in both the axial and radial directions. The wavy shape of the first capsule 1022 guides the insulating oil into laminar flow, reducing flow resistance.

[0058] The second inner shell may include a second capsule 2021 and a second base 2022; the second base 2022 is arranged on the first outer shell 101; one end of the second capsule 2021 is connected to the second base 2022, and the other end of the second capsule 2021 is connected to the second outer shell 201 and is provided with a second connection port; the elastic telescopic component is arranged on the second base 2022.

[0059] As an optional embodiment, the elastic telescopic assembly includes a second sleeve 2041 and a second spring 2042; the second sleeve 2041 is arranged on the second inner shell; the end of the second plug 203 away from the second connection port and the second spring 2042 are both located in the second sleeve 2041, and the two ends of the second spring 2042 are respectively connected to the second sleeve 2041 and the second plug 203.

[0060] Specifically, the second sleeve 2041 may be disposed on the second base 2022;

[0061] The first plug 103 is rotatably connected to the first inner shell, and the first plug 103 cannot move axially relative to the first inner shell. When the second outer shell 201 is inserted into the first outer shell 101, the first plug 103 will gradually press the second plug 203 into the second inner shell. At this time, the second plug 203 will move axially along the second sleeve 2041 and compress 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 re-engage with the second connecting port.

[0062] As an optional embodiment, the first connector 100 further includes two sets of first pin assemblies 106 disposed on the first inner housing; the second connector 200 further includes two sets of second pin assemblies 206 disposed on the second inner housing, the second pin assemblies 206 being configured to connect to the first pin assemblies 106; the first plug 103 and the second plug 203 both have a cross-section in the shape of an "8";

[0063] 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 moves axially along the second sleeve 2041, the guide member 2032 moves along the guide hole 20411 to 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.

[0064] Before the first connector 100 and the second connector 200 are not connected, the two end faces of the first plug 103 correspond to a group of first pin assemblies 106 respectively, and the two end faces of the second plug 203 correspond to a group of second pin assemblies 206 respectively; when the first connector 100 and the second connector 200 are plugged in, 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 staggered with the second pin assembly 206, and the first plug 103 is staggered with the first pin assembly 106. At this time, the first pin assembly 106 and the second pin assembly 206 can be axially docked.

[0065] The working principle of the rotary wet-plug optoelectronic composite connector is as follows: 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 with the engaging groove 2031 of the second plug 203. At this time, the liquid between the first plug 103 and the second plug 203 is discharged, and 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. The first plug 103 is also 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 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; the inner diameter of the first shell 101 is larger than the outer diameter of the second shell 201. As the second shell 201 moves in the first shell 101, the liquid between the first plug 103 and the second plug 203 will eventually be discharged from the gap between the first shell 101 and the second shell 201.

[0066] The first plug 103 presses the second plug 203 into the second inner shell, and the second plug 203 moves axially along the second sleeve 2041 and compresses the second spring 2042. At the same time, the guide member 2032 moves along the guide hole 20411 to drive the second plug 203 to rotate relative to the second sleeve 2041, and the first plug 103 and the second plug 203 are engaged with each other, so that the first plug 103 rotates relative to the first inner shell. The rotation angle of the first plug 103 and the second plug 203 is 90 degrees. At this time, the second plug 203 is staggered with the second pin assembly 206, and the first plug 103 is staggered with the first pin assembly 206. Components 106 are staggered, and the second pin component 206 moves axially and will eventually dock with the first pin component 106; when the second outer shell 201 compresses the first inner shell to slide relative to the first outer shell 101, the first inner shell will compress the first spring 109 to deform, and the first plug 103 disengages from the first connection port and moves to the inside of the second inner shell with the second plug 203, and the seal 205 gradually transitions from the outer wall of the second plug 203 to the outer wall of the first inner shell to form a seal. During this process, the seal 205 can prevent liquid from entering the first inner shell or the second inner shell, so that the sealing effect of the rotary wet-plug optoelectronic composite connector is better.

[0067] 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, and the first spring 109 will drive the first inner shell to move toward the side of the second connector 200, and finally the first connection port and the first plug 103 are resealed; the second spring 2042 will drive the second plug 203 to move toward the second connection port, and at the same time, with 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, and finally the second plug 203 is resealed with the second connection port.
