Description

Technical Field

[0001] This invention belongs to the field of connector technology, and specifically relates to an optoelectronic conversion connector with optical port decoupling function. Background Technology

[0002] With increasingly fierce international competition, accelerated equipment iteration, and the evolution of warfare, circular active connectors in the military field have been upgraded from "basic components" to "information hubs." Currently, equipment composition is more complex, informatization is more comprehensive, the amount of information transmitted between devices is larger, and the information transmission rate requirements are higher. Traditional circular photoelectric conversion active connectors mostly borrow existing electrical connector interfaces for design, and secondary design at the rear of the connector leads to complex connection structures, resulting in large product size, long length, and heavy weight, which affects the installation and application of circular photoelectric conversion active connectors.

[0003] Active optoelectronic connectors integrate the optoelectronic conversion module and fiber optic connector within an electrical connector accessory, forming an electrical interface for optical transmission. This fundamentally eliminates the problem of fiber optic connector contamination and significantly improves the environmental resistance of optical transmission. Currently common active optoelectronic connectors internally house an optoelectronic conversion module and an MT fiber optic connector. The coupling between the MT fiber optic connector's fiber optic connector end face and the optoelectronic conversion module is typically achieved through epoxy resin sealing, which prevents decoupling between the MT fiber optic connector end face and the optoelectronic conversion module. Therefore, during maintenance, both the active optoelectronic connector and the optical cable must be disassembled and repaired simultaneously. Summary of the Invention

[0004] To address the technical problem of the inability to decouple the optical port of the aforementioned photoelectric conversion active connector, this invention provides a photoelectric conversion connector with optical port decoupling function.

[0005] The objective of this invention is achieved through the following technical solution. According to this invention, a photoelectric conversion connector with optical port decoupling function includes a connector housing and an insulating component disposed within the connector housing. The insulating component includes an insulator and a contact element inserted into the insulator. A partition is disposed within the connector housing, and a photoelectric conversion module is disposed on the partition. The photoelectric conversion module is electrically connected to the contact element. The photoelectric conversion module includes an optical fiber socket. An optical cable is connected to the tail of the connector. An optical fiber plug is disposed at the end of the optical fiber within the optical cable for mating with the optical fiber socket. The optical fiber plug is fixedly positioned on an optical fiber plug positioning block. After the optical fiber plug is mated with the optical fiber socket, the optical fiber plug positioning block can be detachably connected to the partition.

[0006] Compared with the prior art, the advantages of the present invention are: The fiber optic plug is positioned and fixed on the fiber optic plug limit block. The optical signal is transmitted through the fiber optic plug and the fiber optic socket, thereby achieving decoupling of the optical port and facilitating on-site disassembly and maintenance.

[0007] Furthermore, the fiber optic plug limiting block has plug limiting grooves and potting grooves distributed front and back, with the plug limiting grooves and potting grooves connected. The tail of the fiber optic plug is nested in the plug limiting groove and pressed against the rear side wall of the plug limiting groove. The fiber optic cable passes through the potting groove, and the potting groove is filled with glue, so that the fiber optic cable and the fiber optic plug are bonded and fixed on the fiber optic plug limiting block.

[0008] Furthermore, the rear end of the fiber optic plug limiting block is provided with a fixing ear, the fixing ear is provided with a through hole, and the rear end of the partition is provided with a threaded hole. The fiber optic plug limiting block is fixed on the partition by passing a screw through the through hole and screwing it into the threaded hole. The screw is screwed into the threaded hole along the insertion direction of the fiber optic plug.

[0009] Compared with the prior art, the advantages of the present invention are: The fiber optic plug limiting block is fixed on the partition with screws to ensure a secure connection between the fiber optic plug and the fiber optic socket.

[0010] Furthermore, photoelectric conversion modules are provided on both sides of the partition, and the photoelectric conversion modules are fixed to the partition with screws.

[0011] Compared with the prior art, the advantages of the present invention are: After the photoelectric conversion module is fixed on the partition, the module is installed by inserting the partition into the connector housing. Photoelectric conversion modules are installed on both sides of the partition to achieve multi-channel signal transmission and processing, enabling high-speed signal transmission and processing.

[0012] Furthermore, the photoelectric conversion module is electrically connected to the contact via the rigid-flex printed circuit board. The devices on the photoelectric conversion module are mounted on the printed circuit board of the rigid-flex printed circuit board, which is mounted on the partition. The contact is connected to the rigid board of the rigid-flex printed circuit board, and the rigid board and the printed circuit board are connected via the flexible board of the rigid-flex printed circuit board.

[0013] Compared with the prior art, the advantages of the present invention are: By using a rigid-flex printed circuit board to connect the contacts to the devices on the photoelectric conversion module, cables are avoided, thus preventing confusion and difficulty in installation. At the same time, it is convenient to combine the insulating components, photoelectric conversion module and partition and insert them into the connector housing.

[0014] Furthermore, a heating element is installed on one side of the printed circuit board, and an optical fiber socket is installed on the other side.

[0015] Compared with the prior art, the advantages of the present invention are: The heat-generating device is located on one side of the printed circuit board, and the fiber optic socket is located on the other side, which facilitates the separate setting of the heat dissipation structure and the optical port decoupling structure, so that the two structures do not interfere with each other.

[0016] Furthermore, a module heat sink is provided on the printed circuit board to contact the device. The other side of the module heat sink is a heat dissipation slope I. A gap is formed between the heat dissipation slope I and the inner wall of the connector housing. A heat dissipation slider is inserted into the gap. The gap gradually decreases in the insertion direction of the heat dissipation slider. One side of the heat dissipation slider is a heat dissipation slope II that matches the heat dissipation slope I), and the other side matches the inner wall of the housing. During the process of inserting the heat dissipation slider into the gap, the heat dissipation slider can gradually press against the inner wall of the housing and the module heat sink.

[0017] Compared with the prior art, the advantages of the present invention are: Push the wedge-shaped heat dissipation slider into the rear of the housing, and push the heat dissipation slider between the module heat sink and the housing. The module heat sink contacts the heat-generating device, and the upper and lower surfaces of the heat dissipation slider contact and press the module heat sink and the housing respectively, ensuring that the heat dissipation path is open and improving heat dissipation efficiency.

[0018] Furthermore, the connector housing is a circular housing, the surface of the heat dissipation slider that matches the inner wall of the connector housing is a heat dissipation arc surface, and the inner wall of the connector housing is threaded with a nut II for pressing and blocking the heat dissipation slider.

[0019] Compared with the prior art, the advantages of the present invention are: The heat dissipation slider enables heat dissipation from the circular housing and ensures full contact between the slider and the housing, increasing the heat dissipation channel. Nuts can be used to press and tighten the heat dissipation slider between the housing and the module heat sink, ensuring full contact between the slider, the module heat sink, and the housing.

[0020] Furthermore, the insulator is stopped forward and anti-rotation limited within the connector housing, the front end of the partition is stopped forward and anti-rotation limited at the rear end of the insulator, the partition is anti-rotation limited within the connector housing, and a stopper is provided within the connector housing for stopping the partition backward.

[0021] Compared with the prior art, the advantages of the present invention are: The photoelectric conversion module is integrated inside the connector housing. By embedding and fixing a partition, the insulating components are pressed and the photoelectric conversion module is supported and fixed. Assembly is completed between the clamping plates installed at the tail of the partition, which realizes the miniaturization and weight reduction of the product and ensures the secure installation of the internal components of the connector, preventing them from falling off in vibration environment and ensuring normal operation.

[0022] Furthermore, a tailpiece is connected to the rear end of the connector housing, and the tailpiece is sealed to the connector housing by a sealing ring.

[0023] Compared with the prior art, the advantages of the present invention are: A sealing ring is used to achieve a seal between the connector housing and the tail attachment after the tail attachment is installed inside the connector housing.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] An embodiment of the present invention provides a photoelectric conversion connector with optical port decoupling function, such as... Figures 1 to 23 As shown, the connector includes a splined housing 1, an insulating component 2, a partition 3, a photoelectric conversion module 4, a heat dissipation module 5, nut I 6, nut II 7, a corrugated spring 8, an MT fiber optic plug 9, a fiber optic plug limiting block 10, and a tail attachment 11. The description focuses on the mating end of the connector.

[0029] An insulator component 2 is disposed within the inner cavity of the front end of the spline housing 1, matching the shape of the inner cavity. The insulator component 2 includes an insulator 22 and contacts 24. Multiple contacts 24 are distributed on the insulator 22, and the contacts 24 are electrically connected to the photoelectric conversion module 4 inside the spline housing 1 by welding. In this embodiment, the connector is a circular connector, and the spline housing 1 is a cylindrical housing with a cylindrical inner cavity. Since the insulator component 2 matches the inner cavity of the spline housing 1, the shape of the insulator 22 is also cylindrical.

[0030] The photoelectric conversion module 4 is used to convert optical signals into electrical signals. The photoelectric conversion module 4 includes a printed circuit board 45. Devices for photoelectric conversion are distributed on one side of the printed circuit board 45. These devices are prone to heat generation during operation, requiring heat dissipation. Therefore, a module heat sink 43 is also provided on this side to conduct heat to the heat-generating devices. One side of the module heat sink 43 is matched and contacted with each heat-generating device. An MT fiber optic socket 44 is provided on the other side of the printed circuit board 45. A flexible circuit board 46 is connected to the front end of the printed circuit board 45, and a rigid circuit board 41 is connected to the other end of the flexible circuit board 46. Termination holes corresponding to the contact members 24 are distributed on the rigid circuit board 41. The tail end of the contact member is inserted into the termination hole and fixed by soldering, achieving electrical connection between the contact member 24 and the rigid circuit board 41. The rigid circuit board 41 is electrically connected to the flexible circuit board 46, and the flexible circuit board 46 is electrically connected to the printed circuit board 45 and the devices on it. The printed circuit board 45, flexible circuit board 46, and rigid circuit board 41 form a rigid-flex printed circuit board, with the printed circuit board 45 being a rigid board. The photoelectric conversion module 4 transmits optical signals through the MT fiber optic socket 44. The optical signal is input into the MT fiber optic socket 44, and the optical signal is converted into an electrical signal by the devices on the printed circuit board 45 and then transmitted out through the contact 24. The electrical signal input into the contact 24 is converted into an optical signal by the devices on the printed circuit board and then transmitted out through the MT fiber optic socket 44.

[0031] A partition 3 is provided inside the spline housing 1, and photoelectric conversion modules 4 are provided on both sides of the partition 3. Rigid plates 41 on the two photoelectric conversion modules 4 are welded to contact parts 24 in different areas of the insulator 2. Two flexible plates 46 are bent in opposite directions from the rear end face of the insulator 2 and connected to the printed circuit board 45. The two sides of the partition 3 are matched with the inner wall 104 of the spline housing 1. The outer wall of the rear end of the insulator 22 is cut flat to form a notch, and the bottom of the notch forms an insulator limiting surface 23. Two insulator limiting surfaces 23 are symmetrically arranged on the outer wall of the rear end of the insulator 22. Partition limiting blocks 32 matching the notch at the rear end of the insulator are provided on both sides of the front end of the partition 3. The two partition limiting blocks 32 are respectively located at the notch positions on both sides of the insulator 22. The inner surface of the partition limiting block 32 matches the insulator limiting surface 23, and the outer surface of the partition limiting block 32 is an arc surface that matches the inner wall 104 of the spline housing 1. A partition limiting protrusion 31 protrudes from the front end face of one of the partition limiting blocks 32. An insulator limiting groove 25 is provided on the outer wall of the front side of the notch on the insulator 22. When the partition limiting block 32 matches the insulator limiting surface 23, the partition limiting protrusion 31 is inserted into the insulator limiting groove 25.

[0032] Both sides of the partition 3 are provided with threaded structures 33. The printed circuit board 45 is provided with printed circuit board mounting holes 42 corresponding to the positions of the threaded structures. Screws are passed through the printed circuit board mounting holes 42 and screwed into the threaded structures 33 to fix the photoelectric conversion module 42 on the partition 3.

[0033] The partition 3 is positioned relative to the insulator component 2, and the insulator component 2 and the partition 3 are respectively fixed to the photoelectric conversion module 4 to form an assembly. The assembly is then inserted into the rear end of the spline housing 1. The outer wall of the front end of the insulator 2 is provided with an insulator fixing groove 21, and the inner wall of the front end of the spline housing 1 is provided with a housing fixing block 101. After the assembly is inserted into the spline housing 1, the housing fixing block 101 is inserted into the insulator fixing groove 21, and the rear end face of the housing fixing block 101 abuts against the rear side wall of the insulator fixing groove 21, thereby preventing the insulator component 2 from rotating and blocking it axially forward. Through the positioning of the housing fixing block 101, the front end face of the insulator 22 is made flush with the front end face 102 of the spline housing 1.

[0034] To prevent the partition plate 3 from separating from the insulator component 2 during the insertion of the assembly into the spline housing 1, adhesive is applied to the mating position of the partition plate 3 and the insulator component 2 after they are engaged, thus initially fixing the partition plate 3 and the insulator component 2.

[0035] A partition anti-rotation block 34 is provided on the surface of the rear end of the partition 3 that matches the inner wall of the spline housing 1. A housing anti-rotation groove 103 is provided on the inner wall of the rear end of the spline housing 1. When the assembly is inserted into the spline housing 1, the partition anti-rotation block 34 is inserted into the housing anti-rotation groove 103 to achieve anti-rotation of the partition 3 in the spline housing 1.

[0036] After the assembly is inserted into the spline housing 1, a gap is formed between the two module heat sinks 43 and the inner wall 104 of the spline housing 1, and a heat sink slider 5 is inserted into the gap.

[0037] The outer surface of the module heat sink 43 forms a heat dissipation slope I 431, which gradually increases the gap between the module heat sink 43 and the inner wall 104 of the housing from front to back, so that the heat dissipation slider 5 can be inserted into the gap from back to front. The inner surface of the heat dissipation slider 5 forms a heat dissipation slope II 53, which makes the heat dissipation slider 5 a wedge with a gradually decreasing thickness from back to front. The heat dissipation slope II 53 matches the heat dissipation slope I 431, and the heat dissipation slider 5 can be inserted into the gap between the module heat sink 43 and the inner wall 104 of the housing. The outer surface of the heat dissipation slider 5 forms a heat dissipation arc surface 52, which fits against the inner wall 104 of the housing.

[0038] The inner wall of the rear end of the spline housing 1 is threaded, and the rear end of the partition 3 is provided with a partition stop block 36. A nut I6 is screwed into the spline housing 1 from the rear end, and the nut stop surface I61 of the nut I6 presses against the partition stop block 36, thereby fixing the partition 3 and the insulator component 2 inside the spline housing 1. The rear end of the nut I6 is provided with a nut slot I62, which facilitates the use of tools to screw the nut I6 into the spline housing 1.

[0039] The rear end of the heat dissipation slider 5 is provided with a slider stop block 51, which bends inward and extends backward to avoid the nut I6. Nut II7 is screwed into the spline housing 1 from the tail end. Nut II7 is thicker than nut I6, and the step on the inner wall of nut II7 forms a nut stop surface II71. After nut II7 is screwed in, the nut stop surface II71 presses against the slider stop block 51, allowing the heat dissipation slider 5 to insert into the gap between the module heat sink 43 and the inner wall 104 of the housing, and ensuring that the heat dissipation module 5 can press against the module heat sink 43 and the inner wall 104 of the housing, guaranteeing the integrity of the heat dissipation path. The rear end of nut II7 is provided with a nut slot II72, facilitating the use of tools to screw nut II7 into the spline housing 1.

[0040] The heat-generating device on the printed circuit board 45 inside the splined housing 1, the module heat sink 43, the heat dissipation slider 5, and the splined housing 1 together form the connector's heat dissipation structure. The heat from the heat-generating device on the printed circuit board 45 is dissipated to the outside along the module heat sink 43, the heat dissipation slider 5, and the splined housing 1, thus achieving heat dissipation for the connector. This heat dissipation structure can also be used for other connectors with heat-generating devices that need to conduct heat to the housing, and is not limited to the miniaturized circular photoelectric conversion connector mentioned above.

[0041] The tail of the MT fiber optic plug 9 is connected to the optical fiber 91. The fiber optic plug limiting block 10 has a plug limiting groove 1001 at the front end, a potting groove 1002 in the middle, and fixing ears 1003 on both sides of the rear end. The plug limiting groove 1001 is connected to the potting groove 1002. The tail of the MT fiber optic plug 9 is nested in the plug limiting groove 1001 and pressed against the rear side wall of the plug limiting groove 1001. The optical fiber 91 passes through the potting groove 1002. Glue is poured into the potting groove 1002 to bond and fix the optical fiber 91 and the MT fiber optic plug 9 to the fiber optic plug limiting block 10. The MT fiber optic plug 9 is inserted into the MT fiber optic socket 44 to realize the optical signal transmission between the photoelectric conversion module 4 and the MT fiber optic plug 9. The fixing ear 1003 has a through hole, and the rear end face of the partition stop block 36 has a threaded hole 35. The threaded hole 35 avoids the nut I6. A screw is passed through the through hole and screwed into the threaded hole 35 to fix the fiber optic plug limiting block 10 to the partition 3. The screw is screwed into the threaded hole 35 along the insertion direction of the MT fiber optic plug 9 to achieve a firm insertion between the MT fiber optic plug 9 and the MT fiber optic socket 44.

[0042] The tail of the spline housing 1 is threadedly connected to a tail attachment 11, which is fitted onto the tail of the spline housing 1. The tail attachment 11 is fitted and fixed onto the optical cable, and the optical cable branches into several optical fibers 91 within the tail attachment. The ends of the optical fibers 91 are connected to corresponding MT optical fiber plugs 9. The outer wall of the tail of the spline housing 1 is provided with a sealing ring groove 105, and a sealing ring 105 is nested within the sealing ring groove. After the tail attachment 11 is fitted and fixed onto the spline housing 1, the inner wall of the front end of the tail attachment 11 is pressed against the sealing ring, thereby achieving a seal between the tail attachment 11 and the spline housing 1.

[0043] The inner wall of the tail attachment 11 is provided with a tail attachment step 111. The corrugated spring 8 is inserted into the tail attachment 11 from the front end and abuts against the front end surface of the tail attachment step 111. Then the tail attachment 11 and the tail thread of the spline housing 1 are tightened. The tail attachment 11 is used to cover the sealing ring on the spline housing 1 to achieve a waterproof effect.

[0044] The advantages of this invention are summarized as follows: 1. The photoelectric conversion module 4 is integrated inside the spline housing 1 of the circular connector. The insulator component 2 is pressed and fixed by the embedded and fixed partition 3, and the photoelectric conversion module 4 is supported and fixed. The assembly is completed by installing the nut Ⅰ6 at the tail of the partition 3 to press the partition 3, thereby realizing the miniaturization and weight reduction of the product.

[0045] 2. Push the wedge-shaped heat dissipation slider 5 into the rear end of the spline housing 1. Use nut II 7 to push the heat dissipation slider 5 between the photoelectric conversion module 4 and the spline housing 1. The upper and lower surfaces of the heat dissipation slider 5 contact and press the photoelectric conversion module 4 and the spline housing 1 respectively to ensure the heat dissipation path is open and improve the heat dissipation efficiency.

[0046] 3. The MT fiber optic plug 9 is positioned and glued to the fiber optic plug limiting block 10. The optical signal is transmitted through the MT fiber optic plug and the MT fiber optic socket 44, thereby achieving decoupling of the optical port and facilitating on-site disassembly and maintenance. The fiber optic plug limiting block 10 is fixed on the partition 3 with screws to achieve a firm connection between the MT fiber optic plug 9 and the MT fiber optic socket 44.

[0047] The installation process of this invention is summarized as follows: 1. Weld the two photoelectric conversion modules 4 to the insulating component 2; 2. The two electrical conversion modules 4 are fixed to the partition plate 3 as one unit by screws. After the front end of the partition plate 3 is engaged with the insulator component 2, it can be fixed by dispensing glue. 3. Insert the assembly of partition 3, photoelectric conversion module 4, and insulator component 2 into spline housing 1. Align the key positions between insulator component 2 and spline housing 1 (i.e., insert housing fixing block 101 into insulator fixing groove 21 of insulator component 2). At this time, partition anti-rotation block 34 at the tail of partition 3 is inserted into housing anti-rotation groove 103 of spline housing 1. Insert two heat dissipation sliders 5 into the gap between module heat dissipation block 43 of photoelectric conversion module 4 and spline housing 1 respectively. 4. Install nut I6 to push and tighten the fixed partition 3; 5. Install nut II7 to push and tighten the heat dissipation slider 5; 6. Attach and fix the MT fiber optic plug 9 to the fiber optic plug limiting block 10, then insert the MT fiber optic plug 9 so that it is inserted into the MT fiber optic socket 44, and use screws to fix the fiber optic plug limiting block 10 to the tail of the partition 3. 7. A corrugated spring 8 is nested inside the tail attachment 11, and a sealing ring is nested at the tail of the spline housing 1. The tail attachment 11 is fixed to the tail of the spline housing 1 by threads.

[0048] In other embodiments, the heat dissipation structure described above can also be applied to other types of connectors, such as... Figures 24 to 29 As shown. The connector includes a splined housing 1, which can also be replaced with other types of connector housings. A printed circuit board 45 is fixedly disposed inside the splined housing 1. The printed circuit board 45 can be fixed inside the splined housing 1 by a bracket (not shown in the figure). A module heat sink 43 is disposed on the printed circuit board 45, and one side of the module heat sink 43 is in mating contact with the heat-generating device on the printed circuit board 45. A heat dissipation slope I 431 is provided on the side of the module heat sink 43 away from the printed circuit board 45, so that the gap between the module heat sink 43 and the inner wall 104 of the splined housing 1 gradually increases from front to back.

[0049] The module heat sink 43, together with the printed circuit board 45, is inserted into the spline housing 1 and fixed on the bracket inside the spline housing 1. There is a large gap between the module heat sink 43 and the spline housing 1, which provides operating space for the module heat sink 43 and the printed circuit board 45 to be installed into the spline housing 1 and fixed on the bracket, making assembly quick.

[0050] The heat dissipation slider 5 is inserted into the gap between the module heat sink 43 and the inner wall 104 of the spline housing 1. One side of the heat dissipation slider 5 matches the heat dissipation inclined surface I 431, and the other side matches the inner wall 104 of the housing, so that the heat dissipation slider 5 forms a wedge. After the heat dissipation slider 5 is inserted into the gap between the module heat sink 43 and the spline housing 1, it can be pressed tightly against the heat dissipation inclined surface I 431 and the inner wall 104 of the housing, ensuring the continuity and integrity of the heat dissipation path.

[0055] In other embodiments, improvements are made based on the above embodiments, and the printed circuit board 45 on the partition 3 can be electrically connected to the contact 24 on the insulator component 2 via a wire.

[0056] In other embodiments, improvements are made based on the above embodiments. Nut I6 and Nut II7 can be replaced with elastic open-type retaining rings or other types of stoppers. Correspondingly, a groove is made on the inner wall of the rear end of the connector housing, and the retaining ring is installed in the groove to stop the partition plate 3 and the heat dissipation slider 5.

[0057] In other embodiments, improvements are made based on the above embodiments. The module heat sink 43 and the heat sink slider 5 can be replaced with an integral heat sink bump.
