[0073] Traditional connectors require separate connections between the optical fiber section and the electrical wire section of the optical fiber composite cable, making the connection between the connector and the optical fiber composite cable overly complicated.

[0074] An exemplary embodiment of this application provides an optoelectronic composite connection device and adapter, which can improve the assembly efficiency between the optoelectronic composite cable (hereinafter referred to as composite cable) and the plug during use, and simplify the use of the plug.

[0075] Please refer to Figure 1. An embodiment of this application provides an optoelectronic composite connection device, including: a housing assembly 200, a first electrode 4, a second electrode 5, a connector 11, and a flexible ferrule assembly 300.

[0076] The housing assembly 200 has an internal receiving space for accommodating the resilient ferrule assembly 300 and the connector 11. The housing assembly 200 has a contact end 19 with a cylindrical connection structure. The resilient ferrule assembly 300 has a protruding end 100 that protrudes from the contact end 19. The protruding end 100 and the contact end 19 are coaxial cylindrical structures.

[0077] The connector 11 has a through slot extending in a first direction, which is the direction in which the protruding end 100 points to the contact end 19; the through slot is used to accommodate the optical fiber portion 72 of the composite cable 7.

The first electrode 4 is electrically connected to a first connecting portion 41 and a second connecting portion 42. The second electrode 5 includes a third connecting portion 51 and a fourth connecting portion 52 that are electrically connected. In use, the first connecting portion 41 is electrically connected to the first wire portion 71 of the composite cable 7, and the third connecting portion 51 is electrically connected to the second wire portion 73 of the composite cable 7. This allows the embodiment to better transmit electrical signals in the composite cable 7. The optical fiber portion 72 of the composite cable 7 is directly inserted into the elastic ferrule assembly 300 via the connector 11 and coupled to the elastic ferrule assembly 300 to transmit optical signals in the composite cable 7. In the above structure, the contact end 19 is used to connect the optoelectronic composite connection device and the transmission component used in conjunction with it. The protruding end 100 is used to transmit optical signals in the composite cable 7. The first electrode 4 and the second electrode 5 are used to transmit electrical signals in the composite cable 7. The optoelectronic composite connection device provided in this application uses a cylindrical contact end 19, which enables the housing assembly 200 to achieve non-directional insertion. One of the first electrode 4 and the second electrode 5 has a ring structure formed on the contact end 19, which, together with the protruding end 100 of the cylindrical structure, allows the elastic ferrule assembly 300, the first electrode 4, or the second electrode 5 to be inserted without a specific angle. Therefore, the cylindrical housing assembly 200, the cylindrical elastic ferrule assembly 300, and the ring electrode in this application embodiment can satisfy the non-directional insertion of the optoelectronic composite connection device in this application embodiment, achieve blind insertion, and better complete the transmission of optoelectronic signals.

[0081] Furthermore, referring to Figure 1, the housing assembly 200 includes a front housing 1, a rear housing 2, and a tail housing 3;

[0082] Contact end 19 is provided at one end of the front housing 1, and the other end of the front housing 1 is connected to the rear housing 2;

[0083] The rear housing 2 is provided with a plurality of locking plates 21 at the end away from the front housing 1, and the plurality of locking plates 21 are arranged in a ring at intervals around the first direction;

[0084] Along the first direction, the tail sleeve housing 3 includes a pressing part 31, a connecting part 33, and a clamping part 32; the size of the pressing part 31 gradually increases along the first direction, the tail sleeve housing 3 is connected to the rear housing 2 through the connecting part 33, the pressing part 31 is sleeved on the outside of a plurality of locking plates 21 and presses the plurality of locking plates 21 radially to lock the composite cable 7, the clamping part 32 simultaneously presses the first connecting part 41 and the third connecting part 51 to make the first electrode 4 electrically connected to the first wire part 71 of the composite cable 7, and the second electrode 5 electrically connected to the second wire part 73 of the composite cable 7.

[0085] This embodiment of the application includes a front housing 1, a rear housing 2, and a tail housing 3 that are interconnected.

Simultaneously, the pressing part 31 presses multiple locking plates to lock the composite cable 7, completing the locking process. The connecting part 32 can have a threaded structure, allowing the rear housing 2 and the tail housing 3 to connect. During the connection process, the pressing part 32 and the pressing part 31 can also be driven to move simultaneously, making the overall structure of the optoelectronic composite connection device simpler.

[0086] Furthermore, please refer to Figure 12. The second connecting part 42 has a circular structure, and the connector 11 is fixed to the rear housing 2. The second connecting part 42 and the connector 11 are an integral structure.

[0087] And / or, the fourth connecting part 52 is a circular structure, the connector 11 is fixed to the rear housing 2, and the fourth connecting part 52 and the connector 11 are an integral structure.

This embodiment does not specifically limit the specific configuration. Taking the second connecting part 42 and the connector 11 as an integral structure as an example, in the above scheme, the second connecting part 42 can be umbrella-shaped, spherical, or other shapes, thus enabling this embodiment to meet different requirements. To adapt to the above configuration, the adapter body 8 of this embodiment also changes, specifically: the circular slot 81 no longer has a slot. Based on this design, this embodiment can meet different requirements.

[0089] Referring to Figures 1 and 2, the second connecting portion 42 penetrates the front housing 1 and is located inside the receiving space formed by the front housing 1. In the above structure, in this embodiment, the second connecting portion 42 is disposed inside the receiving space, and the fourth connecting portion 52 is configured as a ring structure, with the radial dimension of the ring structure gradually decreasing along the first direction. In this embodiment, the second connecting portion 42 and the fourth connecting portion 52 are respectively disposed on the inner and outer sides of the front housing 1, thereby facilitating the further transmission of positive and negative electrical signals.

[0095] In the above structure, the first connecting part 41 is configured as a first bending structure, which is a hook with a wire-accommodating cavity in the middle, mainly used to lock the wire part 71. In actual use, the wire part 71 is located inside the first bending structure. The pressing part 32 continuously presses the first bending structure, making the internal volume of the first bending structure smaller, so as to press the wire part 71 into the interior of the first bending structure, thus completing the locking of the wire part 71 by the first connecting part 41.

[0096] Alternatively, the third connecting part 51 can be configured as a second bending structure, which is a hook with a wire-accommodating cavity in the middle, mainly used to lock the wire part 71.

In this embodiment, the first connecting part 41 and the third connecting part 51 are set to the same plane, so that when the user pre-installs the wire part 71, it is convenient for the user to place the wire part 71 at the positions of the first connecting part 41 and the third connecting part 51, and then it is convenient for the clamping part 32 to press the wire part 71 to the positions of the first connecting part 41 and the third connecting part 51 respectively, thus completing the electrical connection process of the wire part 71.

[0099] Both the first connecting part 41 and the third connecting part 51 are located on the outside of the housing assembly 200. The first electrode 4 is electrically connected to the first wire part 71 of the composite cable 7, and the second electrode 5 is electrically connected to the second wire part 73 of the composite cable 7, so as to better complete the transmission of electrical signals.

[0100] Please refer to Figures 3 and 4. The flexible ferrule assembly 300 includes a ferrule 12 and a first elastic element 14. The ferrule 12 is located at the end of the connector 11 away from the rear housing 2, and one end protrudes from the front housing 1 to form a cylindrical structure. The first elastic element 14 is located at the end of the connector 11 near the rear housing 2, and the first elastic element 14 abuts against both the connector 11 and the rear housing 2. In use, the ferrule 12 is mainly used for optical coupling with an external fiber optic ferrule. The addition of the first elastic element 14 allows the ferrule 12 to have a certain floating distance in the front housing 1, thereby buffering the force during optical coupling between the ferrule 12 and the external fiber optic ferrule, ensuring the reliability of optical coupling between the ferrule 12 and the external fiber optic ferrule, and thus ensuring stable signal transmission. The first elastic element 14 can be a spring. The connector 11 is provided with a first limiting surface 112, and the rear housing 2 is provided with a second limiting surface 23; the first elastic member 14 is disposed in the limiting space formed by the first limiting surface 112 and the second limiting surface 23; when in use, the two ends of the first elastic member 14 that are far apart from each other abut against the first limiting surface 112 and the second limiting surface 23 respectively, thereby applying a force toward the ferrule 12 to the connector 11 at all times, ensuring that the ferrule 12 can be optically coupled with the external optical fiber ferrule, and ensuring stable signal transmission.

[0101] Referring to Figure 3, the optoelectronic composite connection device also includes a locking member 13. The locking member 13 is sleeved on the outside of the connector 11 and is used to compress the connector 11, thereby reducing the size of the through slot inside the connector 11. In actual use, when the optical fiber 72 is inserted into the through slot, the locking member 13 compresses the through slot during the sliding process with the connector 11, reducing the size of the through slot and locking the optical fiber 72, thus improving the stability of the installation between the optical fiber 72 and the connector 11. In addition to its installation function, the through slot also guides the optical fiber 72, ensuring that the optical fiber 72 can contact the ferrule 12 to complete optical coupling.

[0102] Referring to Figure 4, the front housing 1 of this embodiment is provided with a stop surface 17 inside, and the connector 11 is provided with a contact surface 113; wherein, the stop surface 17 and the contact surface 113 limit the maximum distance of the connector 11 to move in the front housing 1, thereby avoiding excessive movement or sliding of the connector 11.

[0103] Please refer to Figure 3. The locking member 13 can slide relative to the connector 11, and along the first direction, the locking member 13 has a first end and a second end that are far apart from each other, and the size of the first end is larger than the size of the second end.

[0104] Alternatively, the size of the first end is smaller than the size of the second end; that is, the locking member 13 is set as a tapered structure with a certain angle, which causes the size of the locking member 13 in the axial direction to continuously change. In addition, a notch extending in the first direction is opened on the periphery of the through slot. When the locking member 13 locks the connector 11, the size of the through slot will decrease along with the size of the locking member 13 in the axial direction. In addition, the locking member 13 in this embodiment is also provided with a drive groove 131, which is mainly used by the user to drive the locking member 13 relative to the connector 11 through the drive groove 131 after the optical fiber part 72 is inserted into the inside of the through slot. Specifically, referring to Figure 3, when the cone-shaped structure of the locking member 13 faces to the left in Figure 3, that is, the smaller end of the cone-shaped structure of the locking member 13 is on the left, the user needs to move the locking member 13 to the left. The locking member 13 will then squeeze the through groove. When the diameter of the through groove becomes smaller, the side wall of the through groove will lock the optical fiber part 72, completing the fixed installation of the optical fiber part 72 and improving the stability of the connector 11 in this embodiment. When the cone-shaped structure of the locking member 13 faces to the right in Figure 3, that is, the smaller end of the cone-shaped structure of the locking member 13 is on the right, the user needs to move the locking member 13 to the right, and the locking member 13 will then squeeze the through groove.

[0105] Please refer to Figures 3 to 5. A snap-fit ​​assembly can also be provided between the front housing 1 and the rear housing 2. The snap-fit ​​assembly includes a male snap fastener 22 and a snap-fit ​​groove 15 that mates with the male snap fastener 22.

[0106] In this embodiment, the male snap-fit ​​22 is disposed on the rear housing 2, and the snap-fit ​​groove 15 is disposed on the front housing 1; or, the male snap-fit ​​22 is disposed on the front housing 1, and the snap-fit ​​groove 15 is disposed on the rear housing 2; when the front housing 1 and the rear housing 2 are connected, the male snap-fit ​​22 partially protrudes from the snap-fit ​​groove 15. This embodiment adds a snap-fit ​​component to allow the front housing 1 and the rear housing 2 to be installed via a snap-fit ​​connection. In actual use, the rear housing 2 is mainly used to install the wire part 71. When the wire part 71 is installed on the rear housing 2, the rear housing 2 will snap-fit ​​with the front housing 1 through the cooperation between the male snap-fit ​​22 and the snap-fit ​​groove 15. The specific installation position of the male snap-fit ​​22 and the snap-fit ​​groove 15 is not specifically limited in this application, as long as the male snap-fit ​​22 and the snap-fit ​​groove 15 are respectively disposed on the front housing 1 and the rear housing 2. Other snap-fit ​​methods are also within the scope of protection of this embodiment.

[0107] Please refer to Figures 3, 5, and 7. A first latching part 16 is provided on the outer side of the contact end 19. The first latching part 16 is connected to the front housing 1 through the first elastic arm 101. A sliding sleeve body 6 is slidably sleeved on the outer side of the front housing 1. The sliding sleeve body 6 can press the first elastic arm 101 toward the inner side of the front housing 1 so that the first latch moves toward the inner side of the front housing 1. The first latching part 16 is used to engage with the sliding sleeve body 6 to prevent the sliding sleeve body 6 from falling off the front housing 1.

[0108] Please refer to Figures 5 and 7. The front housing 1 has a slot 102 for avoiding the movement of the first elastic arm 101 and / or the first latching part 16. In this embodiment, by opening a circular slot 81 in the front housing 1, it is convenient for the first elastic arm 101 and / or the first latching part 16 to partially protrude from the front housing 1 and complete the engagement with the sliding body 6, thereby preventing the sliding body 6 from falling off the front housing 1.

[0109] Please refer to Figure 7. Along the first direction, the sliding sleeve body 6 has a pressing section 62 and a sliding section 63; the size of the sliding section 63 is larger than the size of the pressing section 62; the inner sidewall of the pressing section 62 is in contact with the outer sidewall of the front housing 1; the sliding sleeve body 6 has an unlocking position and a non-unlocking position relative to the front housing 1. When the sliding sleeve body 6 is in the unlocked position, the first latching part 16 is located inside the front housing 1. When the sliding sleeve body 6 is in the non-unlocked position, the first latching part 16 is located inside the groove. In actual use, the user drives the sliding section 63 to control whether the pressing section 62 abuts against the first elastic arm 101 and / or the first latching part 16. The inner sidewall of the pressing section 62 contacts the outer sidewall of the front housing 1, which facilitates the pressing section 62 pressing the first latching part 16 into the front housing 1. In addition, the distance between the inner sidewall of the sliding sleeve body 6 and the outer sidewall of the front housing 1 is less than the distance by which the male latch 22 protrudes from the front housing 1, so that the first latching part 16 will not protrude from the front housing 1, which facilitates the disassembly of the optoelectronic composite connection device.

[0110] Specifically, please refer to Figure 7. The pressing section 62 has a groove to avoid the first latching part 16. The first latching part 16 engages with the groove. When the sliding body 6 is in the non-unlocked position, the first latching part 16 protrudes from the groove so that the user can press the first latching part 16 so that the sliding body 6 is no longer engaged with the first latching part 16, making it easier for the sliding body 6 to slide on the front housing 1.

[0111] Please refer to Figure 8. A boss 18 is fixedly provided on the sliding sleeve body 6. The boss 18 is provided on the side surface of the sliding section 63 facing the pressing section 62, and the boss 18 is in contact with the pressing section. The boss 18 is mainly used for positioning during insertion in the embodiment of this application, which facilitates the next step of insertion of the whole.

[0112] The optoelectronic composite connection device also includes a second elastic element 61, which is disposed between the sliding sleeve body 6 and the tail sleeve housing 3. When the tail sleeve housing 3 is installed on the rear housing 22, the second elastic element 61 abuts against the sliding sleeve body 6 and the tail sleeve housing 3 respectively. The second elastic element 61 can also be a spring. Figure 9 shows the case where the sliding sleeve body 6 is not inserted into the adapter body 8. In use, the user can insert the connector through the sliding sleeve body 6 or the tail sleeve housing 3. When installing using the sliding sleeve body 6, the front end face of the sliding sleeve body 6 drives the entire front housing 1 into the adapter body 8. However, during this process, there may be cases where the sliding sleeve body 6 is not inserted in place, which will result in a lack of reliable engagement between the latching part 16 and the latching groove 85. Therefore, the addition of the second elastic element 61 ensures that when the connector is inserted using the tail sleeve housing 3, the second elastic element 61 always applies a force towards the adapter body 88 to the sliding sleeve body 6, ensuring that the sliding sleeve body 6 will not be in a disengaged action, thereby ensuring the normal operation of the front housing 1.

[0113] Please refer to Figure 11. A second slot 93 is provided in a ring on the outer side of the contact end 19. The addition of the second slot 93 also facilitates the next insertion step in the embodiment of this application.

[0114] Please refer to Figures 8 and 9. This application embodiment provides an adapter, including an adapter body 8. The adapter body 8 has a circular slot 81, an optical connection portion, and two electrode connection portions formed inside. The optical connection portion and the two electrode connection portions are all disposed inside the circular slot 81, and at least one electrode connection portion has a ring structure. The circular slot 81 is used to accommodate a cylindrical connection structure in an optoelectronic composite connection device. When the optoelectronic composite connection device is inserted into the circular slot 81, the optical connection portion couples with the ferrule 12 in the optoelectronic composite connection device, and the two electrode connection portions are respectively connected to the optoelectronic composite connection. The first electrode 4 and the second electrode 5 in the device are in contact. When the optoelectronic composite connection device in this embodiment is used, it needs to be used with the adapter body 8. When the housing 1 is inserted into the circular slot 81, the first electrode 4 and the second electrode 5 are in contact with the two electrode connection parts respectively. The two electrode connection parts are in contact with the second electrode contact end 82 and the first electrode contact end 83 respectively, so as to transmit the electrical signal to the adapter body 8. The insert 12 is in contact with the optical connection part to transmit the optical signal to the adapter body 8, thereby completing the complete signal transmission process.

[0115] Please refer to Figures 8-10. The adapter also includes a first locking element, which is a first slot 85 annularly opened in the circular slot 81. When the optoelectronic composite connector is inserted into the circular slot 81, the first latching part 16 in the optoelectronic composite connector engages with the first slot 85. The sliding sleeve body 6 in the optoelectronic composite connector slides and presses the first latching part 16 to release the first latching part 16 from the first slot 85. When the front housing 1 is inserted into the circular slot 81, the first latching part 16 is located inside the first slot 85. The sliding sleeve body 6 is used to drive the first latching part 16 to move away from the first slot 85. When the first latching part 16 in this embodiment is disposed on the front housing 1, the embodiment of this application further provides a sliding body 6, wherein the sliding body 6 will engage with the first latching part 16 during use to prevent the sliding body 6 from falling off the front housing 1; in addition, the distance between the inner sidewall of the sliding body 6 and the outer side of the front housing 1 is less than the distance by which the male latch 22 protrudes from the front housing 1, and when it is necessary to unlock the front housing 1 from the adapter body 8, the sliding body 6 only needs to move away from the adapter body 8 on the front housing 1 to squeeze the first latching part 16 into the interior of the front housing 1, so that the first latching part 16 is no longer locked with the first latching groove 85, thus completing the disassembly process of the front housing 1.

[0116] Furthermore, referring to Figures 11 and 13, the adapter also includes a second locking member, which includes a second latching part 86 and a second elastic arm 87. The second latching part 86 is disposed inside the circular slot 81 via the second elastic arm 87. When the optoelectronic composite connector is inserted into the circular slot 81, the second latching part 86 engages with the second slot 93 in the optoelectronic composite connector. In the above structure, when the second latching part 86 is disposed in the adapter body 8, the second slot 93 is disposed in the front housing 1. That is, the second latching part 86 is disposed inside the circular slot 81. The second latching part 86 itself has a certain guiding structure, so when the front housing 1 is inserted into the circular slot 81, the second latching part 86 will first move away from the second slot 93 to avoid the insertion of the front housing 1, and then the second latching part 86 will move closer to the second slot 93 to complete the engagement of the front housing 1.

[0117] Please refer to Figure 13. The adapter also includes an unlocking component, which is located on the adapter body 8 and is used to unlock the connection between the adapter body 8 and the optoelectronic composite connection device.

[0118] Please refer to Figure 11. The unlocking component includes an elastic drive member 91, an unlocking switch 9, and a push rod 92. The push rod 92 contacts the second elastic arm 87. The unlocking switch 9 can drive the push rod 92 to move relative to the adapter body 8 through the elastic drive member 91. The push rod 92 can press the second elastic arm 87 away from the photoelectric composite connection device, so that the second latching part 86 moves away from the second slot 93. It is worth noting that the push rod 92 has a first station and a second station. When the push rod 92 is in the first station, it does not contact the first latching part 16. When the push rod is in the second station, it contacts the second latching part 86 and drives the first latching part 16 to move away from the second slot 93. The elastic drive member 91 is used to drive the push rod 92 to switch between the first station and the second station. In the above structure, when the second latching part 86 is provided on the adapter body 8, the second slot 93 is provided on the front housing 1, that is, the second latching part 86 is provided inside the circular slot 81. The device has a guiding structure, so when the front housing 1 is inserted into the circular slot 81, the second latching part 86 first moves away from the second slot 93 to avoid the insertion of the front housing 1. Then, the second latching part 86 moves closer to the second slot 93 to lock the front housing 1 in place. Simultaneously, when it is necessary to remove the front housing 1 from the adapter body 8, the unlocking switch 9 is manually activated. Under the action of the elastic drive member 91, the unlocking switch 9 drives the push rod 92 to move, which in turn opens the second latching part 86, thus unlocking the front housing 1. Furthermore, the addition of the elastic drive member 91 ensures that the push rod 92 does not actively exert force on the second latching part 86 without external interference, facilitating its use in this embodiment.

[0119] Please refer to Figure 8. The adapter body 8 is also provided with a positioning groove 84 with an opening facing the axis of the circular slot 81. Along the insertion direction of the optoelectronic composite connector, the positioning groove 84 has a guide surface that is inclined towards the axis of the circular slot 81. The positioning groove 84 corresponds to the boss 18 in the optoelectronic composite connector. The addition of the guide surface will cause the boss 18 to automatically fall into the positioning groove 84, further improving the ease of installation.
