[0028] The embodiment of the present invention discloses a petal-type watertight optical connector to reduce the number of openings for integrating multi-channel optical signals in terminal equipment and reduce the risk of multiple failure links caused by a large number of openings.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 2 , Figure 1 It is a schematic cross-sectional structure diagram of a split-flap watertight optical connector according to a specific embodiment of the present invention; Figure 2 for Figure 1 Side view of the middle socket housing 7.

[0031] In a specific embodiment, the split-flap watertight optical connector provided by the present invention includes a socket 15 and a plurality of plugs 14 mating with the socket 15 .

[0032] Among them, the socket 15 includes a socket shell 7 and a plurality of socket watertight optical cables 4, and the socket shell 7 is used for sealing and fixed connection with the underwater working equipment, for example, sealing and fixed connection with the cabin of the underwater working equipment. Specifically, the socket shell 7 includes an insertion portion inserted into the equipment mounting hole of the underwater working equipment and a flange portion protruding to abut against the end face of the hole of the equipment mounting hole. Then, a mounting groove can be provided on the insertion portion, such as two mounting grooves are arranged at intervals, and a sealing ring 16 is arranged in the mounting groove to contact and seal with the inner wall of the equipment mounting hole. As needed, a mounting groove can also be provided on the flange portion, and a sealing ring 16 is arranged in the mounting groove to contact and seal with the end face of the hole of the equipment mounting hole, and the longitudinal water blocking of the socket 15 and the underwater working equipment, that is, the external water blocking of the socket 15 is ensured by sealing in two directions.

[0033] The socket housing 7 has a plurality of optical channels, and the heads of the watertight optical cables 4 of each socket are sealed and fixed to one side of the optical channels. That is, the socket housing 7 is provided with optical channels for installing the watertight optical cables 4 of the sockets, and the specific number of optical channels can be set as required, such as the attached Figure 2 In the embodiment, five optical channels are provided, and one side in each optical channel is sealed and fixedly installed with a socket watertight optical cable 4. The other side in the optical channel is used for sealing and fixing the plug 14 respectively.

[0034] The head of each watertight optical cable 4 has a socket optical pin 17, which contacts the plug optical pin 19 of the plug 14 to realize the conduction of the entire optical circuit. The specific structure of the socket optical pin 17 and the plug optical pin 19 can be referred to the prior art and will not be repeated here.

[0035] The plug 14 includes a plug housing 10 and a plug watertight optical cable 11. The plug watertight optical cable 11 is sealed and fixedly connected to the plug housing 10. The head of the plug watertight optical cable 11 has a plug optical pin 19. Each plug 14 is inserted into the other side of the corresponding optical channel so that the plug optical pin 19 contacts the corresponding socket optical pin 17. Each plug 14 is fixedly connected to the socket housing 7 to ensure reliable contact between the plug optical pin 19 and the socket optical pin 17. The plug housing 10 is sealed and connected to the optical channel. In combination with the sealed connection between the plug watertight optical cable 11 and the plug housing 10, and the sealed connection between the head of the socket watertight optical cable 4 and the optical channel, the longitudinal water blocking inside the plug 14 and the socket 15 is achieved, and underwater application can be achieved.

[0036] By using the split-petal watertight optical connector provided by the present invention, a plurality of socket watertight optical cables 4 are sealed and fixed in the socket housing 7, and each plug 14 is inserted into one side of the optical channel of the socket housing 7, so that the optical pin 19 of each plug contacts the corresponding socket optical pin 17 on the other side of the optical channel, thereby conducting the optical circuit. Therefore, a plurality of split-petal watertight plugs 14 can be connected through one socket 15, which solves the problem of integrating the optical signals of a plurality of information terminals into one channel of the receiving terminal and entering the interior of the receiving terminal. The aesthetics of the product appearance design, the convenience of assembly operation, and the convenience of maintenance and replacement are greatly improved. And because a plurality of plugs 14 can be matched through one socket 15, the receiving terminal only needs to open a hole for installing the socket 15, thereby reducing the space occupied. And it also reduces the risk of failure links caused by a large number of holes opened at a large water depth.

[0037] Furthermore, each watertight optical cable 4 of each socket is sealed with a water-blocking pressure sleeve 18, the end of the optical pin 17 of the socket is fixedly connected to the water-blocking pressure sleeve 18, and the water-blocking pressure sleeve 18 is sealed and connected to the optical channel. Specifically, the water-blocking pressure sleeve 18 is inserted into the watertight optical cable 4 of the socket, and the optical pin 17 of the socket is made at the end of the watertight optical cable 4 of the socket. After the grinding and testing are completed, the optical pin 17 of the socket and the water-blocking pressure sleeve 18 are bonded and fixed together to form an optical unit as a whole. The provision of the water-blocking pressure sleeve 18 facilitates the sealing between the watertight optical cable 4 of the socket and the socket housing 7.

[0038] Furthermore, the socket housing 7 has a mounting hole on one side, and a plurality of jacks 20 connected to the mounting hole and used for inserting the plug 14 on the other side. The mounting hole is fixed with a docking component 5 and a water-blocking component 3. The optical channel includes a plurality of docking through holes provided on the docking component 5, a water-blocking through hole provided on the water-blocking component 3 and corresponding to one side of the docking through hole, and jacks 20 respectively provided on the other side of the docking through hole. That is, the mounting hole on one side of the socket housing 7 is used to seal and fix the watertight optical cable 4 of the socket, and the plurality of jacks 20 on the other side are respectively used to insert the plug 14. The docking component 5 and the water-blocking component 3 are fixedly installed in the mounting hole, and the water-blocking component 3 is located on the side of the docking component away from the jack 20. The docking component 5 is provided with a plurality of docking through holes, and the water-blocking component 3 is provided with a plurality of water-blocking through holes. The water-blocking through holes, the docking through holes and the jacks 20 are respectively provided in a one-to-one correspondence. That is, one end of each water-blocking through hole is connected to the corresponding docking through hole, and the other end is connected to the corresponding jack 20. The optical channel includes a water-blocking through hole, a docking through hole and a plug hole 20 that are connected in sequence. According to the shape of the mounting hole, the shapes of the docking component 5 and the water-blocking component 3 are set accordingly. If the mounting hole is a circular hole, the water-blocking component 3 can be a water-blocking circular plate, and the docking assembly can be called a docking circular plate. It should be noted that the docking component 5 and the water-blocking component 3 can be two separate components, which are respectively installed in the mounting holes, and the docking component 5 is located on the side of the water-blocking component 3 away from the plug hole 20. As needed, the docking component 5 and the water-blocking component 3 can also be an integrated structure.

[0039] The above optical units are respectively inserted into the water-blocking through hole and the docking through hole to form an optical channel assembly. Specifically, the socket optical pin 17 is inserted into one side of the docking through hole, and the plug optical pin 19 is inserted into the other side of the docking through hole to contact and conduct with the socket optical pin 17, that is, the plug optical pin 19 and the socket optical pin 17 are aligned and contacted in the docking component 5, thereby conducting the corresponding optical circuit. The water-blocking pressure sleeve 18 is inserted into the water-blocking through hole and is sealed with the inner wall of the water-blocking through hole, and the water-blocking component 3 is sealed with the socket shell 7. Through the sealed connection between the water-blocking pressure sleeve 18 and the inner wall of the water-blocking through hole and the sealed connection between the water-blocking component 3 and the inner wall of the mounting hole, the sealing between the water-blocking pressure sleeve 18 and the water-blocking component 3, and the water-blocking component 3 and the socket shell 7 is achieved, thereby achieving the longitudinal sealing inside the socket shell 7. The above structural arrangement facilitates the assembly of the various components of the socket 15, and the sealing reliability is high.

[0040] The water-blocking component 3 is fixedly connected to the docking component 5 and the socket shell 7. Specifically, a fixing nut 1 can be set on the side of the water-blocking component 3 away from the docking component 5. The fixing nut 1 is fixedly connected to the socket shell 7 and presses the docking component 5 and the water-blocking component 3 into the mounting hole. The fixing nut 1 is used to fasten the components inside the mounting hole, which is convenient for installation and reliable for fixation. Specifically, a pressing plate 2 is provided between the fixing nut 1 and the water-blocking component 3. Of course, holes for the socket watertight optical cable 4 to pass through should be provided on the fixing nut 1 and the pressing plate 2. During installation, the optical channel assembly is inserted as a whole into the corresponding key position of the socket shell 7, and then the pressing plate 2 is installed into the socket shell 7, and the fixing nut 1 is used to press the pressing plate 2 and the front optical channel assembly.

[0041] The water-blocking pressure sleeve 18 is sealedly connected to the inner wall of the water-blocking through hole. Specifically, an annular installation groove is provided on the outer wall of the water-blocking pressure sleeve 18, and a sealing ring 16 is arranged in the installation groove to seal with the water-blocking through hole. That is, at least one circle of installation groove is provided on the outer wall of the water-blocking pressure sleeve 18, and the sealing ring 16 is installed in the installation groove. When the water-blocking pressure sleeve 18 is inserted into the water-blocking through hole, the sealing ring 16 is squeezed between the water-blocking pressure sleeve 18 and the water-blocking component 3 to achieve longitudinal sealing between the two.

[0042] The water blocking component 3 is sealed and connected to the inner wall of the mounting hole. Specifically, an annular mounting groove is provided on the inner wall of the mounting hole corresponding to the water blocking component 3, and a sealing ring 16 is provided in the mounting groove to seal with the water blocking component 3. That is, at least one circle of mounting grooves is provided on the inner wall of the mounting hole, and the sealing ring 16 is installed in the mounting groove. When the water blocking component 3 is inserted into the mounting hole, the sealing ring 16 is squeezed between the water blocking component 3 and the socket housing 7 to achieve longitudinal sealing between the two.

[0043] Specifically, two mounting grooves may be provided on the outer wall of the water-blocking pressure sleeve 18 , and two mounting grooves may be provided on the inner wall of the mounting hole. The aforementioned seals form a longitudinal seal inside the socket housing 7 .

[0044] In order to further improve the sealing reliability, a socket casting 6 is arranged outside the fixing nut 1, and the socket casting 6 bonds the socket watertight optical cable 4 to the socket shell 7. That is, the socket casting 6 is arranged on the side of the fixing nut 1 away from the water blocking component 3. The socket casting 6 can effectively bond the socket shell 7 to the socket watertight optical cable 4, thereby enhancing the fastening and water blocking effects. And when the socket shell 7 is a metal shell, the socket casting 6 has the ability to bond metal and rubber to ensure the sealing effect.

[0045] On the basis of the above embodiments, the outer wall of the plug housing 10 has a flange in the middle, the jack 20 includes an inner hole with the same size as the front end of the flange of the plug 14 and an outer hole with the same size as the flange, a step surface is formed between the inner hole and the outer hole, a clamping nut 9 is arranged outside the plug 14, the clamping nut 9 is fixedly connected to the socket housing 7 to compress the flange, and an elastic member 8 is arranged between the flange and the clamping nut 9. A step surface is formed between the inner hole and the outer hole of the jack 20, the plug optical pin 19 is inserted into the other side of the optical channel, the plug housing 10 is inserted into the jack 20, and is fixedly connected to the socket housing 7 through the clamping nut 9, and the elastic member 8 is pressed on the flange to compress it, so that the plug optical pin 19 and the socket optical pin 17 are in contact and connected. By setting the elastic member 8, the plug 14 can float relative to the optical channel in the longitudinal direction, and when the docking component 5 is provided, the plug optical assembly can float relative to the docking component 5. The use of a separate floating alignment structure can adjust the deviation caused by manufacturing and assembly errors and control the insertion loss within a specified range. The flange is provided to facilitate the installation of the elastic member 8, and the flange and the step surface abut to limit the insertion limit position of the plug 14.

[0046] The elastic member 8 may specifically be a spring, and other conventional elastic material members and structural members may also be used as required.

[0047] Furthermore, the plug housing 10 has a plug casting 12, which bonds the plug housing 10 and the plug watertight optical cable 11 together. The plug casting 12 can effectively bond and fix the plug housing 10, the plug watertight optical cable 11 and the plug optical pin 19 into a whole, thereby enhancing the fastening and water blocking effects. When the plug housing 10 is a metal housing, the plug casting 12 has the ability to bond metal and rubber to ensure a sealing effect.

[0048] According to the needs, in the above embodiments, a vulcanization sleeve 13 is provided at the tail of the plug housing 10 to connect the plug housing 10 with the plug watertight optical cable 11 as a whole. The vulcanization sleeve 13 vulcanizes the plug housing 10 and the plug watertight optical cable 11 into one, and together with the plug casting 12, realizes water blocking of this part, further ensuring the reliability of water blocking.

[0049] In the above embodiments, a mounting groove is provided on the plug housing 10, and a sealing ring 16 is provided in the mounting groove to seal with the inner wall of the plug hole 20. That is, at least one circle of mounting groove is provided on the outer wall of the plug housing 10, and the sealing ring 16 is installed in the mounting groove. When the plug 14 is inserted into the plug hole 20, the transversely installed sealing ring 16 is squeezed between the plug 14 and the socket housing 7 to achieve longitudinal sealing between the two.

[0050] On the basis of the above embodiments, the socket shell 7 and the plug shell 10 are both metal shells. Specifically, the socket shell 7 and the plug shell 10 can be made of stainless steel, such as 316L stainless steel. As required, other metals resistant to seawater corrosion, such as aluminum alloy and titanium alloy with anodized surface, can also be used. The fixing nut 1, the pressing plate 2, the water-blocking component 3, the docking component 5, the pressing nut 9, and the water-blocking pressure sleeve 18 involved in the above embodiments can also be made of stainless steel, such as 316L stainless steel. As required, other metals resistant to seawater corrosion, such as aluminum alloy and titanium alloy with anodized surface, can also be used. Optical fiber is used to transmit signals and is protected by metal structures. It is not easy to age, has high mechanical strength, wide signal transmission band, large communication capacity, low signal loss, not easily affected by electromagnetic wave interference, and small signal delay. It has better adaptability to the harsh environment of the deep sea, and plays an irreplaceable role in high-definition video transmission and synchronous signal transmission. It provides a more reliable and higher-performance option for the application of related industries, and the economic benefits are considerable.

[0051] It should be noted that the thickness of the sealing ring 16 disposed in the installation groove in the above embodiments should be greater than the depth of the installation groove, so that the sealing ring 16 is squeezed to achieve effective sealing. As required, the sealing between the components can also adopt other conventional sealing methods such as labyrinth sealing, and is not limited to the sealing of the sealing ring 16. However, the sealing structure of the sealing ring 16 is simple, and the overall coordination can achieve underwater application of 3000 meters.

[0052] In the above embodiments, the specific number of optical channels can be set as needed, and the plug 14 is set corresponding to the optical channel. Each plug 14 serves as a petal, and each petal can have one optical fiber, which is for single-core optical cables. Then the socket watertight optical cable 4 in each channel also corresponds to one optical fiber. The petal-type watertight optical connector can also be applied to multi-core optical cables, that is, the same number of optical fiber loops are added to each petal, the plug 14 uses the corresponding multi-core optical cable, and the socket 15 also uses the multi-core optical cable accordingly. The number of petals can also be increased or decreased. According to the actual system requirements, the calculation results and trade-offs between the water depth, the opening size and the bulkhead thickness are applied. Specifically, the number of petals can be 2-96, and the number of cores on each petal can be 1-8 cores.

[0053] In summary, the split-flap watertight optical connector provided by the present application connects multiple split-flap watertight plugs 14 through a dense socket 15, which solves the problem of integrating the optical signals of multiple information terminals into one channel of the receiving terminal to enter the interior of the receiving terminal. The aesthetics of the product appearance design, the convenience of assembly operation, and the convenience of maintenance and replacement have been greatly improved. The split-flap watertight optical connector solves the problem of the large number of cabin openings and large space required for the use of multiple pairs of optical connectors, and reduces the risk of failure links caused by the large number of openings at great water depths. The economy of product processing and the safety of the product have been significantly improved. It plays a key role in the development of related industries and technological progress, and has achieved significant economic and social benefits.
