[0004] The present invention relates to the technical field of optical communications, and in particular to an optoelectronic composite connector integrating multiple optoelectronic channels. Background Art

[0005] The existing technology center often simply applies optoelectronic composite cables to deploy optical fiber cables and energy transmission lines together. During use, the optical cables and electrical cables at both ends are connected to optical fiber connectors and electrical sockets respectively, and then the light and electricity are directly inserted into the corresponding sockets to implement networking. Most of them use POE (Power Over Ethernet) optoelectronic composite connectors. The POE optoelectronic composite connectors are mostly designed with optoelectronic composites on LC optical interfaces or SC optical interfaces, and the LC (Line Connector) optical interface or SC (Subscriber Connector) optical interface are single-core optical fibers, which are single-core ceramic round holes. There are fewer optical channels under this design, and the existing multi-fiber connectors are MT connectors and MPO connectors. None of the above connectors are integrated with electrical channels, resulting in priority applicability in application scenarios where multiple optical fibers send and receive signals in parallel. Therefore, when multiple optical fibers are required to simultaneously take into account the transmission of electrical signals and electrical energy, the above existing products cannot be realized.

[0061] Embodiment 1:

[0062] Embodiment 1 of the present invention provides an optoelectronic composite connector integrating multiple optoelectronic channels, as shown in FIG1 , comprising: an optoelectronic composite connector 1 and an optoelectronic composite socket 2 , wherein:

[0063] As shown in FIG. 2 , the front end of the optoelectronic composite connector 1 includes a central connector 11 and a peripheral connector 12 . The peripheral connector 12 is arranged around the circumference of the central connector 11 .

[0064] As shown in Figure 2, the central connector 11 and the peripheral connector 12 in this embodiment are located at the front end of the optoelectronic composite connector 1, and the rear end of the optoelectronic composite connector 1 is a shell, which is usually made of plastic. The central connector 11 and the peripheral connector 12 are both arranged on the end surface of the shell for insertion into the optoelectronic composite socket 2; in this embodiment, the central connector 11 is in the shape of a rectangular parallelepiped and is arranged in the center of the end surface of the shell, and the peripheral connector 12 is in the shape of a hollow cylinder and is arranged around the central connector 11. As shown in Figure 2, the peripheral connector 12 is a hollow rectangular parallelepiped, which fits the shape of the central connector 11 in the center, and there is a space between the central connector 11 and the peripheral connector 12 to distinguish the two connectors.

[0065] As shown in FIG2 , the end surface of the central connector 11 is provided with at least two plug-side optical interfaces 13 ; the side surface of the peripheral connector 12 is provided with at least two plug-side electrical interfaces 14 .

[0066] As shown in FIG3 and FIG4 , the front end of the optoelectronic composite socket 2 includes a socket slot 21 , the inner end surface of the socket slot 21 is provided with at least two socket-side optical interfaces 22 , and the inner side wall of the socket slot 21 is provided with at least two socket-side electrical interfaces 23 .

[0067] The end face of the central connector 11, which is the outward-facing side of the central connector 11 in Figure 2 , is provided with at least two plug-side optical interfaces 13 for transmitting optical signals. The side face of the peripheral connector 12, which is the upper side face of the peripheral connector 12 in Figure 2 , is provided with at least two plug-side electrical interfaces 14. As shown in Figures 3 and 4 , the socket-side electrical interface 23 is provided on the lower side wall of the inner side wall of the socket slot 21 in Figure 4 .

[0068] It should be noted that, in this embodiment, the plug-side optical interface 13 is a multi-fiber arrangement of an MT connector or an MPO connector standard, and the plug-side optical interface 13 is arranged in an array on the end face of the central connector 11 .

[0069] When the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the plug-side optical interface 13 is connected to the socket-side optical interface 22 for transmitting optical signals, and the plug-side electrical interface 14 is connected to the socket-side electrical interface 23 for transmitting electrical signals.

[0070] In this embodiment, the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, which means that: the optoelectronic composite connector 1 is connected to the optoelectronic composite socket 2, wherein the end face of the central connector 11 abuts against the inner end face of the socket slot 21 of the optoelectronic composite socket 2, and the side face of the peripheral connector 12 abuts against the inner side wall of the socket slot 21, ensuring that the plug-side optical interface 13 is connected to the socket-side optical interface 22, and the plug-side electrical interface 14 is connected to the socket-side electrical interface 23.

[0071] It should be noted that in this embodiment, the types of optical signals transmitted by the optical channel include: one or more of digital signals, analog signals, and high-order modulated signals; the electrical signals transmitted by the electrical channel include: one or more of digital signals, analog signals, high-order modulated signals, time-division multiplexing signals, wavelength-division multiplexing signals, and power carrier signals.

[0072] The existing technology center often uses the optoelectronic composite cable 15 simply to deploy optical fiber cables and energy transmission lines together. During use, the optical cables and electrical cables at both ends are connected to the optical fiber connectors and electrical sockets respectively, and then the light and electricity are directly inserted into the corresponding sockets to implement networking. Most of them use POE optoelectronic composite connectors. The POE optoelectronic composite connectors are mostly designed with optoelectronic composites on LC optical interfaces or SC optical interfaces, and the LC optical interfaces or SC optical interfaces are single-core optical fibers, which are single-core ceramic round holes. There are fewer optical channels under this design, and the existing multi-core connectors are MT connectors and MPO connectors. None of the above connectors are integrated with electrical channels, resulting in priority applicability in application scenarios where multiple optical fibers send and receive signals in parallel. Therefore, when multiple optical fibers are required to simultaneously take into account the transmission of electrical signals and electrical energy, the above existing products cannot be realized.

[0073] In this embodiment, a central connector 11 and a peripheral connector 12 are provided at the front end of the optoelectronic composite connector 1, wherein a plurality of plug-side optical interfaces 13 are provided on the end face of the central connector 11, and a plurality of plug-side electrical interfaces 14 are provided on the side faces of the peripheral connector 12. Correspondingly, a plurality of socket-side optical interfaces 22 and a plurality of socket-side electrical interfaces 23 are provided in the socket slot 21 of the optoelectronic composite socket 2. After the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the plug-side optical interfaces 13 are correspondingly connected to the socket-side optical interfaces 22, and the plug-side electrical interfaces 14 are correspondingly connected to the socket-side electrical interfaces 23, thereby realizing optoelectronic composite transmission of multiple optoelectronic channels.

[0074] In this embodiment, since the optoelectronic composite connector 1 needs to transmit optical signals, electrical signals and electrical energy, it needs to be connected to the optical channel and the electrical channel. Therefore, this embodiment involves the following designs:

[0075] As shown in FIG5 , the rear end of the optoelectronic composite connector 1 is connected to the optoelectronic composite cable 15 , which includes an optical transmission cable and an electrical transmission cable, wherein:

[0076] The optical transmission cable is connected to the plug-side optical interface 13 of the central connector 11 ; the electrical transmission cable is connected to the plug-side electrical interface 14 of the peripheral connector 12 .

[0077] In this embodiment, when the optoelectronic composite cable 15 is docked with the optoelectronic composite connector 1, it is divided into an optical transmission cable and an electrical transmission cable, wherein the optical transmission cable is directly connected to the plug-side optical interface 13 in the central connector 11, while the electrical transmission cable enters the interior of the peripheral connector 12 and is connected to the plug-side electrical interface 14.

[0078] In this embodiment, considering that when transmitting electrical signals or electrical energy, it is necessary to ensure a stable contact connection between the plug-side electrical interface 14 and the socket-side electrical interface 23, but because the plug-side electrical interface 14 is arranged on the side of the peripheral connector 12, and the socket-side electrical interface 23 is arranged on the inner side of the socket side, when the optoelectronic composite connector 1 is inserted into the optoelectronic composite socket 2, the abutment between the plug-side electrical interface 14 and the socket-side electrical interface 23 is not in the insertion force direction. Therefore, if the plug-side electrical interface 14 and the socket-side electrical interface 23 are only in abutment contact between planes, a stable contact connection between them cannot be guaranteed. Therefore, this embodiment also involves the following design:

[0079] As shown in FIG6 , each of the plug-side electrical interfaces 14 includes an interface slot 141 and a metal spring 142 , wherein:

[0080] The interface groove 141 is provided on the side surface of the peripheral connector 12, and the metal spring 142 is connected to the electrical transmission cable and extends from the surface of the peripheral connector 12 through the interface groove 141; when the front end of the optoelectronic composite connector 1 is inserted into the socket groove 21 of the optoelectronic composite socket 2, the metal spring 142 is used to be pressed by the optoelectronic composite connector 1 and connected to the socket-side electrical interface 23.

[0081] In this embodiment, the interface slots 141 are all strip-shaped slots, which lead to the interior of the peripheral connector 12. The power transmission cable enters the interior of the peripheral connector 12 from the rear end housing. One side of the metal spring 142 is connected to the power transmission cable in the interface slot 141, while the other side extends out of the interface slot 141. When the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the portion of the metal spring 142 extending from the interface slot 141 is subjected to pressure from the socket-side electrical channel and is pressed into the interface slot 141. The elastic restoring force of the metal spring 142 itself causes the metal spring 142 to abut against the socket-side electrical channel, ensuring a tight connection between the metal spring 142 and the socket-side electrical channel. When the front end of the optoelectronic composite connector 1 is pulled out of the socket slot 21, the pressure on the portion of the metal spring 142 extending from the interface slot 141 is removed, and the metal spring 142 bounces out of the interface slot 141 again due to the elastic restoring force.

[0082] In this embodiment, as shown in FIG7 to FIG9 , the metal spring 142 includes a long side 1421 , a short side 1422 and a bottom side 1423 , wherein:

[0083] The bottom edge 1423 is located inside the interface groove 141 and is connected to the power transmission cable; one end of the long side 1421 is elastically connected to the bottom edge 1423, and the other end of the long side 1421 extends from the outer end of the interface groove 141 and is elastically connected to one end of the short side 1422 at a preset angle, and the other end of the short side 1422 is immersed in the interface groove 141.

[0084] When the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the optoelectronic composite connector 1 presses the long side 1421, and both the long side 1421 and the short side 1422 are pressed into the interface slot 141. The long side 1421 is used to connect with the socket-side electrical interface 23.

[0085] In this embodiment, as shown in FIG7 , the long side 1421, the short side 1422 and the bottom side 1423 are all strip metals, and the long side 1421, the short side 1422 and the bottom side 1423 are integrally formed, the bottom side 1423 is located inside the interface groove 141, parallel to the surface of the peripheral joint 12, and the long side 1421 and the bottom side 1423 are connected at an acute angle, that is, angle C in the figure; the preset angle is set by those skilled in the art. In this embodiment, the preset angle The angle is obtuse; the outer end of the interface groove 141 is: the end of the interface groove 141 facing the insertion direction; the inner end of the interface groove 141 is: the end of the interface groove 141 facing away from the insertion direction, and the position where the long side 1421 and the short side 1422 are connected is located at the upper end of the interface groove 141 near the middle position; in this embodiment, one end of the long side 1421 is elastically connected to the bottom side 1423, and one end of the short side 1422 is not connected to the inner end of the interface groove 141. As shown in Figures 8 and 9 , when the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2 (the arrows in Figures 8 and 9 indicate the direction of insertion of the optoelectronic composite connector 1), the front end of the optoelectronic composite connector 1 first contacts the long side 1421 and presses the metal spring 142 along the long side 1421. As can be seen from Figures 8 and 9 , the angle C gradually decreases until the front end of the optoelectronic composite connector 1 reaches the apex of the metal spring 142, i.e., the connection point between the long side 1421 and the short side 1422, at which point the metal spring 142 is completely pressed into the interface slot 141. Either the long side 1421 or the short side 1422 can extend downward within the interface slot 141 and connect with the power transmission cable.

[0086] Since the central connector 11 and the peripheral connector 12 are used to transmit optical signals and electrical signals or electrical energy respectively, the two connectors need to be distinguished. In order to ensure that the central connector 11 accurately abuts against the inner end surface of the socket slot 21, thereby ensuring that the plug-side optical interface 13 and the socket-side optical interface 22 can be accurately connected, this embodiment also involves the following designs:

[0087] As shown in Figures 10 and 11, a positioning slot 16 is provided between the central connector 11 and the peripheral connector 12; a positioning boss 24 is provided around the socket side optical interface 22 in the socket slot 21; when the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the positioning boss 24 is used to be inserted into the positioning slot 16.

[0088] In this embodiment, since the peripheral connector 12 is a hollow columnar cube and the central connector 11 is a columnar column, the contour of the positioning slot 16 is a hollow columnar column, and the contour of the positioning boss 24 is consistent with that of the positioning slot 16. When the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the central connector 11 is inserted into the center of the positioning boss 24, thereby positioning the central connector 11.

[0089] After the front end of the photoelectric composite connector 1 is inserted into the socket slot 21 of the photoelectric composite socket 2, since it needs to maintain the inserted state for a long time, the photoelectric composite connector 1 needs to be fixed to the photoelectric composite socket 2 after insertion. Therefore, this embodiment designs the following design:

[0090] As shown in Figures 10 and 11, chamfered clips 25 are provided on both sides of the optoelectronic composite socket 2, and clip grooves 17 are provided on both sides of the peripheral connector 12; when the front end of the optoelectronic composite connector 1 is inserted into the socket groove 21 of the optoelectronic composite socket 2, the chamfered clips 25 are located in the clip grooves 17, and the inner side of the chamfered clips 25 abuts against the inner side wall of the clip groove 17, thereby fixing the optoelectronic composite connector 1 and the optoelectronic composite socket 2.

[0091] Among them, the chamfer at the front end of the chamfered buckle 25 faces the inner side of the socket slot 21, and the inclined surface of the chamfer faces the insertion direction of the optoelectronic composite connector 1. When the optoelectronic composite connector 1 is inserted into the socket slot 21, the optoelectronic composite connector 1 stretches the chamfered buckle 25 toward both sides along the inclined surface of the chamfer until the chamfer reaches the position of the buckle slot 17. The chamfer relies on the rebound force of the chamfered buckle 25 itself to rebound into the buckle slot 17; the inner side of the chamfered buckle 25 is the barb of the chamfer. When the chamfer rebounds into the buckle slot 17, the barb of the chamfer is stuck on the inner wall of the buckle slot 17 to prevent the optoelectronic composite connector 1 from falling out of the optoelectronic composite socket 2.

[0092] In the prior art, conventional optoelectronic composite connectors can only transmit electrical energy but cannot transmit electrical signals. To further improve the integration of the optoelectronic composite connector provided in this embodiment, this embodiment also involves the following designs:

[0093] As shown in Figures 12 to 14, Figure 14 is a schematic end view of the optoelectronic composite connector 1 or the optoelectronic composite socket 2. When the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the socket-side electrical interface 23 and the plug-side electrical interface 14 are connected as an electrical channel, and the electrical channel includes an electrical energy channel A and an electrical signal channel B; wherein, a first preset number of socket-side electrical interfaces 23 and a first preset number of plug-side electrical interfaces 14 are connected as the electrical signal channel B, and a second preset number of socket-side electrical interfaces 23 and a second preset number of plug-side electrical interfaces 14 are connected as the electrical energy channel A.

[0094] In this embodiment, the first preset number and the second preset number are set by those skilled in the art; the power channel A is used to transmit power, and the electrical signal channel B is used to transmit electrical signals; as shown in Figures 12-14, this embodiment also provides a preferred arrangement design of the socket side electrical channels, where every two electrical signal channels B are set adjacent to each other as a group, and each group of electrical signal channels B is separated by a single power channel A, wherein the two electrical signal channels B are set adjacent to each other as a group because: at this stage, the electrical signal needs to be phase-flipped 180 degrees during transmission to ensure the transmission distance of the electrical signal, so each needs to be A group requires at least two adjacent electrical signal channels B for differential setting; since high-frequency electrical signals are often transmitted in the electrical signal transmission channel, adjacent channels may be interfered with by low-frequency signals due to the high-frequency electrical signals. Therefore, this embodiment separates the electrical energy channels A between different groups of electrical signal channels B to avoid interference between different groups of electrical signal channels B; as shown in Figure 14, the large squares represent the electrical energy channels A and the small squares represent the electrical signal channels B. It can be seen that every two electrical signal channels B are adjacently set as a group, and each group of electrical signal channels B is separated by an electrical energy channel A.

[0095] Since the plug-side electrical channel is provided on one side of the peripheral connector 12, and the other side of the peripheral connector 12 is not provided with a plug-side electrical channel, in actual use, the user needs to confirm in advance which side of the optoelectronic composite connector 1 the plug-side electrical channel is located, and which side of the optoelectronic composite socket 2 the socket-side electrical channel is located, so as to connect the plug-side electrical channel and the socket-side electrical channel accordingly. Failure to confirm in advance may cause the optoelectronic composite plug to be inserted upside down, resulting in the plug-side electrical channel and the socket-side electrical channel not being connected accordingly. Pre-confirmation is often cumbersome, resulting in a poor actual use experience. If the user forgets to confirm and directly inserts the connector, it may cause an insertion error, which may have more serious consequences. If it is designed that no prior confirmation is required and the connector is directly inserted, the optoelectronic composite connector 1 will not be able to be inserted directly when it is inserted in reverse. The above design is often more direct and simpler, and can also prevent insertion errors. Therefore, this embodiment has the following design:

[0096] As shown in Figures 15 and 16, a boss 18 is provided on the inner end of the peripheral connector 12 opposite to the plug-side electrical interface 14, and a groove 26 is provided on the inner end of the socket slot 21 opposite to the socket-side electrical interface 23; when the front end of the optoelectronic composite connector 1 is inserted into the socket slot 21 of the optoelectronic composite socket 2, the boss 18 is inserted into the groove 26.

[0097] The above-mentioned boss 18 distinguishes the side of the peripheral connector 12 where the plug-side electrical interface 14 is provided and the side where the plug-side electrical interface 14 is not provided. Moreover, since the side of the socket slot 21 where the socket-side electrical channel is provided is not provided with a corresponding groove 26, when the optoelectronic composite connector 1 is inserted in reverse, the boss 18 will be blocked by the periphery of the socket slot 21, resulting in the optoelectronic composite connector 1 being unable to enter the socket slot 21, directly avoiding the possibility of the optoelectronic composite connector 1 being inserted in reverse. When the user finds that the optoelectronic composite connector 1 cannot be inserted into the optoelectronic composite socket 2, he will know that he has just held the optoelectronic composite connector 1 upside down. At this time, the optoelectronic composite connector 1 can be successfully inserted by turning it 180 degrees and reinserting it, so that the user does not need to confirm in advance when inserting, thereby optimizing the experience during actual use.

[0098] It is worth mentioning that the optoelectronic composite connector with integrated multiple optoelectronic channels provided in this embodiment can be applied to scenarios where multiple signals and electrical energy with different functions and specifications are transmitted in parallel. In an environment where signals and energy of multiple specifications such as HDMI interface, DP interface, USB interface, etc. are mixedly transmitted, the interface and supporting cable equipment of this embodiment can be used to simply and efficiently break through the power, control, interference and distance limitations of pure cable networking, and achieve a higher system level; the data cable connector and data cable can also be designed to adopt the optoelectronic composite cable 15 and active optoelectronic composite cable head in this embodiment on cables for multi-channel and multi-parallel mixed data forwarding, such as RJ45 network cables, USB data cables, etc., to achieve a breakthrough improvement in indicators such as transmission distance, communication rate, application scenarios and deployment and maintenance flexibility.

[0099] Example 3:

[0100] This embodiment 2 is based on embodiment 1, provides an optoelectronic composite connector integrating multiple optoelectronic channels, and demonstrates it in an actual application scenario.

[0101] The optoelectronic composite connector integrating multiple optoelectronic channels provided in this embodiment is applied to a high-performance data acquisition and transmission device with control. The interface definition of the optoelectronic composite connector in this embodiment is shown in Figure 17, wherein optical channels OT1 to OT6 are used to transmit 6 optical signals, optical channels OR1 to OR6 are used to receive 6 optical signals, electrical channels D1P and D1N, electrical channels D2P and D2N, electrical channels D3P and D3N, and electrical channels D4P and D4N are respectively used to transmit high-speed electrical signals, monitoring interface C1 and monitoring interface C2 are used to provide equipment monitoring lines, power supply V1 and power supply V2 together form a loop power supply with ground, and GND is a grounding loop.

[0102] When the high-performance data acquisition and transmission device is started, the GND grounding loop remains connected, the power supply of the source device is powered on and started through the power supply V1 interface, and the device connection is monitored through the monitoring interface C1 to see if it is normal. When the monitoring interface C1 feedbacks that the remote device is started normally, it means that the remote device is in a working ready state at this time. The source device and the remote device communicate through the electrical signal D1P and the electrical channel D1N, the electrical channel D2P and the electrical channel D2N, the electrical channel D3P and the electrical channel D3N, and the electrical channel D4P and the electrical channel D4N. When the communication confirms that the system self-test of the remote device and the source device is normal and has the conditions for starting the function, the source device starts the power supply to supply power to the remote device through the power supply V2, the remote device starts the core functional components, and monitors and feedbacks the working status through the monitoring interface C2. At this time, a large amount of data information is transmitted through the optical channel OT1-optical channel OT6 and the optical channel OR1-optical channel OR6.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
