[0026] 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.

[0027] An embodiment of the present invention provides a blind-mating, rotating, and easy-to-clean wireless optical transmission connector assembly, such as... Figures 1 to 3As shown. It includes a plug and a socket, with the plug being the free end and the socket being the fixed end. For ease of description, the end of each component in the plug and socket closest to the mating end is designated as the front end, and the end furthest from the mating end as the rear end.

[0028] The plug includes a plug nut 1, a first O-ring 2, a plug housing 3, a first transceiver module 4, a fourth O-ring 11, and a first lens 12. The socket includes a beveled spring 5, a second O-ring 6, a nut 7, a ratchet washer 8, a washer 9, a third O-ring 10, a fifth O-ring 13, a second lens 14, a second transceiver module 15, a socket housing 16, a sixth O-ring 17, and a socket nut 18.

[0029] The plug nut 1 has an axially penetrating cavity inside, and an annular boss on its outer wall. The outer wall of the plug nut 1 near the front end is provided with threads, and a first O-ring 2 is nested between the threads and the boss on the outer wall of the plug nut 1.

[0030] The plug housing 3 has an axially penetrating inner cavity. The inner wall of the plug housing 3 is threaded and threadedly connected to the plug nut 1. An annular boss is provided at the rear end of the plug housing 3, and this boss abuts against the boss of the plug nut 1. The plug housing 3 and the plug nut 1 are sealed by a first O-ring 2. The outer diameter of the front part of the plug housing 3 is smaller than the outer diameter of the rear part, and the inner diameter of the front part is also smaller than the inner diameter of the rear part. The threads on the plug housing 3 are located on the inner wall of its rear part. A groove 301 is provided on the outer wall of the front end of the plug housing 3. The front side of the groove 301 is inclined to facilitate the smooth sliding of the inclined coil spring 5 into the groove 301. A chamfer is provided at the front end of the plug housing 3 to facilitate insertion.

[0031] A first transceiver module 4 is nested within the inner cavity of the plug housing 3. The rear end of the first transceiver module 4 is engaged with a step formed between the front and rear parts of the plug housing 3, and the rear end face of the first transceiver module 4 abuts against the front end face of the plug nut 1, thus fixing the first transceiver module 4 within the plug housing 3. A first lens 12 is nested within the inner cavity of the plug housing 3 near the front end. The front end face of the first lens 12 abuts against the inner end face of the front opening of the plug housing 3, and the rear end abuts against the front end face of the first transceiver module 4, thereby fixing the first lens 12 within the plug housing 3 and sealing the front opening of the plug housing 3. A fourth O-ring 11 is nested within the inner wall of the plug housing 3 near the front end to seal the first lens 12 and the plug housing 3.

[0032] The socket housing 16 has a cavity extending axially through the socket housing 16. A second lens 14 and a second transceiver module 15 are nested sequentially within the cavity from front to back. The front end face of the second lens 14 abuts against a step inside the socket housing 16, and the rear end face abuts against the front end face of the second transceiver module 15. The rear end of the second transceiver module 15 is engaged with another step inside the socket housing 16.

[0033] A socket nut 18 is threaded onto the inner wall of the socket housing 16 near the rear end. The rear end face of the second transceiver module 15 abuts against the front end face of the socket nut 18. The outer wall of the socket nut 18 is provided with an annular boss, and the outer wall near the front end is provided with threads. A sixth O-ring 17 is nested between the boss and the threads on the outer wall of the socket nut. The sixth O-ring 17 is used to seal the socket nut 18 and the socket housing 16.

[0034] The cavity at the front end of the socket housing 16 is used to insert a plug. The inner wall of the cavity is nested with a slanted coil spring 5 and a second O-ring 6 from front to back.

[0035] The outer wall of the socket housing 16 is provided with an annular boss, and a third O-ring 10 is nested on the side of the boss facing the front end. A nut 7 is threadedly connected to the outer wall of the socket housing 16 near the front end. A ratchet washer 8 and a washer 9 are nested on the socket housing 16 from front to back between the nut 7 and the boss.

[0036] When the plug and socket are inserted, the front end of the plug housing 3 is inserted into the cavity at the front end of the socket housing 16. As the plug is inserted, the inclined coil spring 5 is compressed by the outer wall of the plug housing 3. When the slot 301 of the plug housing 3 slides to the position of the inclined coil spring 5, the inclined coil spring 5 enters the slot 301 under its own elastic force and is locked in the slot 301. The inclined coil spring 5 achieves axial fixation between the plug and the socket, ensuring that they do not loosen. At this time, the step on the outside of the plug housing 3 is also locked at the front end of the socket housing 16 to prevent excessive force during insertion. The plug housing 3 continues to push inward against the elastic force of the inclined coil spring 5, thereby preventing damage to the components inside the plug housing 3 and the socket housing 16.

[0037] After the plug and socket are inserted, the first lens 12 approaches and aligns with the second lens 14. Both the first transceiver module 4 and the second transceiver module 15 are equipped with photoelectric conversion modules and electro-optical conversion modules. A cable passes through the plug nut 1 and connects to the first transceiver module 4, and the cable is sealed and fixed to the plug nut 1 by a tail accessory. Similarly, another cable passes through the socket nut 18 and connects to the second transceiver module 15, and the socket nut 18 and its corresponding cable are sealed and fixed to the socket nut 18 by another tail accessory.

[0038] When the first transceiver module 4 in the plug functions as a transmitting module, it converts the electrical signal transmitted from the cable into an optical signal via an electro-optical conversion module and transmits it. The optical signal passes through the first lens 12 and is then transmitted to the socket. Next, the optical signal passes through the second lens 14 in the socket and enters the second transceiver module 15. The photoelectric conversion module in the second transceiver module 15 then converts the optical signal into an electrical signal, which is output through the cable in the socket. When the first transceiver module 4 in the plug functions as a receiving module and the second transceiver module 15 functions as a transmitting module, the operation is the reverse of the above process.

[0039] The front ends of the plug and socket do not make direct contact after insertion. There are no key restrictions between the plug housing 3 and the socket housing 16. Furthermore, the light beam emitted by the first transceiver module 4 is transmitted sequentially through the first lens 12 and the second lens 14 and received by the second transceiver module 15. As long as the alignment of the plug housing 3 and the socket housing 16 is ensured, the plug and socket can be inserted and rotated at any angle of 360°.

[0040] The first lens 12 and the second lens 14, located at the front end of the plug and socket, serve not only to allow light signals to pass through but also to protect the first transceiver module 4 and the second transceiver module 15 from external contamination. A fourth O-ring 11 is located between the first lens 12 and the plug housing 3, and a fifth O-ring 13 is located between the second lens 14 and the socket housing 16. These O-rings prevent dust from entering the interior of the plug housing 3 and the socket housing 16. When the surfaces of the first lens 12 and the second lens 14 become dirty, they can be wiped directly without damaging the internal modules, providing easy cleaning.

[0041] Nut 7, ratchet washer 8, and washer 9 form a fixing and anti-loosening structure. When the socket is installed on the panel, the panel is held between washer 9 and the boss of the socket housing 16. Tightening nut 7 brings ratchet washer 8 and washer 9 closer to and presses against the panel, firmly securing the panel between washer 9 and the boss of the socket housing 16, ensuring the socket is fixed and does not loosen. The third O-ring 10 is placed between the boss of the socket housing 16 and the panel to achieve a sealing function.

[0042] The first O-ring 2 is disposed between the plug nut 1 and the plug housing 3, and the sixth O-ring 17 is disposed between the socket housing 16 and the socket nut 18, to achieve the sealing function of the connector tail. A slanted coil spring 5 and a second O-ring 6 are disposed in the cavity at the front end of the socket housing 16. After the plug and socket are inserted, the slanted coil spring 5 holds the plug in place to prevent it from falling off. Simultaneously, the elasticity of the slanted coil spring 5 provides axial cushioning for the plug, preventing damage to both the plug and the socket.

[0043] The plug housing 3 directly engages with the first transceiver module 4, and the socket housing 16 directly engages with the second transceiver module 15. This eliminates the need for intermediate parts. Furthermore, since optical signal transmission is used between the plug and socket connectors, the optical signal is less susceptible to electromagnetic interference. This eliminates the need for shielding at the plug and socket mating positions, simplifying the structure and effectively reducing the radial dimension of the connector product, thus achieving connector miniaturization.

[0044] This connector assembly fills the gap in wireless optical transmission connectors during connector mating and disassembly, while also enabling miniaturized product design. This connector assembly achieves non-contact transmission of optical signals at the connector end face, ensuring the signal is unaffected by electromagnetic interference and the data transmission limitations of traditional pin-hole connectors. The non-contact end face design eliminates the need for contact between the plug and socket signal transmission parts. Combined with the characteristics of the inclined coil spring 5, this allows for 360° blind mating and rotation, preventing end face wear during use and extending product lifespan. Lenses (first lens 12, second lens 14) are added to the front face of the connector to effectively protect the transceiver module surface from damage while ensuring effective optical signal transmission. The lenses are easy to clean by wiping directly when dirty. O-rings are placed between mating components within the connector to effectively prevent dust from entering the connector, avoiding contamination and ensuring overall product sealing. A locking structure with the inclined coil spring 5 at the plug-socket connection provides a push-pull quick-lock function for the connector.

[0045] In Embodiment 2 of the present invention, based on Embodiment 1, the first transceiver module 4 and the second transceiver module 15 in the connector assembly are configured as follows: Figures 3 to 8 The transceiver module shown is illustrated. The first transceiver module 4 and the second transceiver module 15 have the same structure; the first transceiver module 4 will be used as an example for explanation. The first transceiver module 4 includes a housing 401, a first printed circuit board 402, a second printed circuit board 403, components 404, and a convex lens 405. The housing 401 is an axially penetrating cylinder, and the convex lens 405 is disposed inside the housing 401. The back sides of the first printed circuit board 402 and the second printed circuit board 403 are attached together, and multiple pads are circumferentially distributed on the outer circumference of both printed circuit boards. The two printed circuit boards are connected through these circumferentially distributed pads, which also serve as signal transmission channels, avoiding the need for openings inside the printed circuit boards. The pads on the two printed circuit boards correspond one-to-one, and the pads are nested on the outer circumference of the printed circuit boards. Circumferential arc grooves are provided on their outer walls for easy positioning and soldering. The first printed circuit board 402 is fixed to one end of the housing 401, with its front facing the housing 401.

[0046] The first printed circuit board 402 is used for the micro-assembly of the transceiver module. Since multiple components are arranged on its front side, no holes can be made on the surface of the first printed circuit board 402. The second printed circuit board 403 is used for signal extraction. Multiple holes are formed on it, and these holes mate with suitable contacts to achieve electrical connection between the contacts and both the second and first printed circuit boards 402, thereby enabling signal extraction. The remaining micro-assembly components 404 are arranged on the surface of the second printed circuit board 403. The flat surface of the convex lens faces the first printed circuit board 402, and the convex surface faces the front end of the connector.

[0047] Both the first transceiver module 4 and the second transceiver module 15 have photoelectric conversion modules and electro-optical conversion modules on their printed circuit boards, and both are located inside the housing 401 and face the convex lens. A cable passes through the plug nut 1 and connects to the first transceiver module 4. The wires in the cable are electrically connected to the printed circuit board through contacts, and the cable is sealed and fixed to the plug nut 1 by a tail accessory. Similarly, another cable passes through the socket nut 18 and connects to the second transceiver module 15. The wires in the cable are electrically connected to the printed circuit board through contacts, and the socket nut 18 and its corresponding cable are sealed and fixed to the socket nut 18 by another tail accessory.

[0048] When the first transceiver module 4 in the plug functions as the transmitting module, it converts the electrical signal transmitted from the cable into an optical signal via an electro-optical conversion module and transmits it. The optical signal passes through a convex lens within the first transceiver module 4 and is converted into parallel light. The parallel light then passes through the first lens 12 and is transmitted to the socket. Next, the parallel light passes through the second lens 14 in the socket and enters the convex lens in the second transceiver module 15, where it is focused onto the corresponding components on the printed circuit board. The photoelectric conversion module in the second transceiver module 15 then converts the optical signal into an electrical signal, which is output through the cable in the socket.

[0049] This transceiver module utilizes a stacked PCB design, bonding the back sides of two PCBs together to achieve miniaturization. Pads along the circumferential edges of the PCBs enable electrical connections between their sidewalls. This eliminates the need for drilling holes in the first PCB 402, which is densely packed with components; holes are only required in the second PCB 403 to establish electrical connections between the contacts and the PCBs. The stacked design allows for component encapsulation on both sides of the stacked PCBs, effectively utilizing PCB space. Drilling holes in the second PCB 403 uses through-hole designs instead of blind vias on a single PCB, reducing manufacturing complexity and cost. This transceiver module reduces radial dimensions, ensuring miniaturization, and also lowers manufacturing difficulty and cost compared to a single PCB.

[0050] In Embodiment 3 of the present invention, the transceiver module in Embodiment 2 can be applied to other devices separately, rather than just to the connector assembly.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
