Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0033] Please see Figure 1 as well as Figure 2 This application provides an optoelectronic simultaneous transmission connection component, including an adapter 200 and a connector 300. The connector 300 and the adapter 200 are connected to each other to realize the conduction of optical signals and electrical signals. Figure 1 This is a schematic diagram showing the structure where the adapter 200 and connector 300 are separated. Figure 2 This is a schematic diagram of the optoelectronic simultaneous transmission connection assembly formed by the mutual assembly of the adapter 200 and the connector 300. The optoelectronic simultaneous transmission connection assembly in this embodiment is applicable to various occasions such as fiber to the home, fiber to the roadside, fiber to the office, and fiber to the service area.

[0034] Please see Figure 3 The adapter 200 includes a first housing 10, an optical fiber sleeve 22, an optical fiber fixing component 24, and a conductive component 30. The optical fiber sleeve 22, the optical fiber fixing component 24, and the conductive component 30 are all fixedly connected to the first housing 10 to form a whole.

[0035] Please refer to the following: Figure 4The first housing 10 includes a first housing portion 12, a blocking portion 14, an extension portion 16, and a retaining portion 18. A first receiving groove 121 is formed on the first housing portion 12, penetrating the first housing portion 12. The first receiving groove 121 includes a first receiving portion 1211 and a second receiving portion 1213 that communicate with each other. The blocking portion 14 extends from the inner surface of the first housing portion 12 toward the first receiving groove 121, separating the first receiving portion 1211 and the second receiving portion 1213. The extension portion 16 extends from the surface of the blocking portion 14 toward the first receiving portion 1211, and the extension portion 16 is a hollow cylindrical shape. The retaining portion 18 is located at the end of the first housing 10 and extends toward the first receiving portion 1211, meaning the retaining portion 18 protrudes relative to the first housing portion 12.

[0036] The fiber optic fixing member 24 is located in the second receiving portion 1213 and is connected to the surface of the blocking portion 14. The fiber optic sleeve 22 is a hollow cylindrical shape, with one end of the fiber optic sleeve 22 housed in the fiber optic fixing member 24 and the other end extending into the extension portion 16.

[0037] Please refer to the following: Figure 5 The conductive element 30 is a metal spring. In this embodiment, there are two conductive elements 30, which are spaced apart. The conductive element 30 includes a first conductive portion 32, a bent portion 34, and a second conductive portion 36. The bent portion 34 connects the first conductive portion 32 and the second conductive portion 36. Both the first conductive portion 32 and the second conductive portion 36 are bent relative to the bent portion 34. The conductive element 30 is generally Z-shaped and can deform.

[0038] The first housing portion 12 is also provided with a through hole 123, which communicates with the first accommodating portion 1211. A first conductive portion 32 is fixed to the first housing portion 12, passes through the through hole 123, and extends to the outside of the first housing portion 12 for electrical connection with an external circuit (e.g., a circuit board). A bent portion 34 is located in the first accommodating portion 1211. The connection between the bent portion 34 and the first conductive portion 32 is close to the blocking portion 14, while the connection between the bent portion 34 and the second conductive portion 36 is away from the blocking portion 14. The second conductive portion 36 is located in the second accommodating portion 1213, and is spaced apart from the blocking portion 14. When the conductive member 30 is subjected to an external force, the second conductive portion 36 can deform towards the blocking portion 14.

[0039] When assembling the adapter 200, first fix the conductive component 30 to the first housing 10; then place the fiber optic sleeve 22 into the first receiving groove 121 and place the fiber optic fixing component 24 into the second receiving part 1213, with one end of the fiber optic sleeve 22 placed in the fiber optic fixing component 24; finally, weld the fiber optic fixing component 24 to the inside of the first housing 10, thereby completing the assembly of the adapter 200.

[0040] Please see Figure 6 The connector 300 includes a second housing 40, an optical fiber ferrule 60, and a hybrid optical-electric cable 50, with portions of the optical fiber ferrule 60 and the hybrid optical-electric cable 50 housed within the second housing 40.

[0041] Please refer to the following: Figure 7 The second housing 40 includes a second housing portion 42 and a pressing portion 44. The pressing portion 44 is disposed on the outer surface of the second housing portion 42. The pressing portion 44 can deform relative to the second housing portion 42 under the action of external force. One end of the second housing portion 42 can be accommodated in the first receiving groove 121.

[0042] Please refer to the following for details. Figure 9 The second housing portion 42 is generally a cuboid and includes six outer surfaces, namely an upper surface 421, a lower surface 422, two side surfaces 423, a first end face 424, and a second end face 425. The upper surface 421 and the lower surface 422 are arranged opposite to each other, the two side surfaces 423 are arranged opposite to each other, and the first end face 424 and the second end face 425 are arranged opposite to each other.

[0043] The pressing part 44 is provided on the upper surface 421, and the pressing part 44 is inclined outward from the upper surface 421 in a direction away from the first end face 424. The pressing part 44 is provided with a protrusion 442 (see reference). Figure 11 The protrusion 442 interacts with the retaining part 18 to hold the second housing 40 in the first housing 10. Specifically, when one end of the second housing part 42 is received in the first receiving groove 121, the protrusion 442 is held in place by the retaining part 18, and the first housing 10 and the second housing 40 are fixed to each other; when it is necessary to remove the second housing 40 from the first housing 10, the pressing part 44 is pressed until the retaining part 18 releases the restriction on the protrusion 442, and the second housing 40 can be removed from the first housing 10.

[0044] The second housing portion 42 has a second receiving groove 431, which extends through the first end face 424 and the second end face 425. The fiber optic ferrule 60 is housed in the second receiving groove 431.

[0045] Please refer to the following: Figure 8 and Figure 11The optoelectronic hybrid cable 50 includes a main body 52, an optical fiber 54, and two wires 56. The optical fiber 54 and the wires 56 are arranged parallel to each other. One end of each optical fiber 54 and wire 56 is fixed to the main body 52, and the other end protrudes from the main body 52. ​​The end of the optical fiber 54 protruding from the main body 52 is housed in an optical fiber ferrule 60. One end of the optical fiber ferrule 60 can be inserted into an optical fiber sleeve 22, thereby enabling the transmission of optical signals with the adapter 200. The second housing part 42 also has two grooves 433. Each groove 433 passes through the second end face 425 and extends towards the first end face 424. The grooves 433 and the second receiving groove 431 are spaced apart. The end of the wire 56 protruding from the main body 52 is housed in the groove 433.

[0046] The second housing portion 42 also has two recesses 435, each recessed from the first end face 424 toward the second end face 425, and the recesses 435 communicate with the wire groove 433. When the wire 56 is accommodated in the wire groove 433, the end of the wire 56 protrudes from the second housing portion 42 and is accommodated in the recess 435. When the connector 300 is inserted into the adapter 200, the end face is used to abut against the blocking portion 14 in the first housing 10, and the wire 56 accommodated in the recess 435 is used to achieve electrical connection with the conductive member 30.

[0047] Please refer to the following: Figure 6 , Figure 8 and Figure 9 The outer wall of the wire 56 is provided with multiple slots 562, and the inner wall of the wire groove 433 is provided with multiple protrusions 4332 that are adapted to the slots 562. The protrusions 4332 can be locked in the slots 562. When the wire 56 is accommodated in the wire groove 433, each protrusion 4332 is locked in the corresponding slot 562, thereby limiting the wire 56. So that when the connector 300 is inserted into the adapter 200, and the end of the wire 56 is used for electrical connection with the conductive part 30, the wire 56 will not retract due to the interaction between the protrusions 4332 and the slots 562.

[0048] The slot 562 is inclined, and the opening of the slot 562 faces the direction of the main body, that is, the opening of the slot 562 faces the direction of the second end face 425, so that a "barb" structure is formed on the outer wall of the wire 56, so that the wire 56 can be inserted into the wire groove 433 more smoothly, and the protrusion 4332 and the slot 562 can play a mutual holding role.

[0049] The second housing portion 42 also has two first notches 437 and two second notches 439. Each first notch 437 is formed by a recess in the lower surface 422 toward the upper surface 421, and each first notch 437 communicates with a corresponding wire groove 433. Each second notch 439 is formed by a recess in the lower surface 422 and a corresponding side surface 423. Each second notch 439 communicates with the corresponding first notch 437 and the wire groove 433, so that the second body portion forms a movable portion. When the wire 56 is accommodated in the wire groove 433, when the protrusion 4332 contacts the outer wall of the wire 56 where the slot 562 is not provided, it abuts against the inner wall of the wire groove 433, opening the movable portion so that the wire 56 can be accommodated more smoothly in the wire groove 433; when the protrusion 4332 is engaged in the corresponding slot 562, the movable portion can restore its deformation and fit tightly against the outer wall of the wire 56.

[0050] Please refer to it again. Figure 6 The connector 300 may also include a rear housing 71, a ferrule tail 72, a spring 73, a retaining ring 74, a protective tube 75, and a sheath 76.

[0051] The rear housing 71 connects the second housing 40 and the sheath 76. One end of the rear housing 71 is housed in the second housing 40, and the other end of the rear housing 71 is housed in the sheath 76. The retaining ring 74 is fitted onto the rear housing 71 and located between the rear housing 71 and the sheath 76.

[0052] The fiber optic ferrule 60, ferrule tail 72, fiber optic cable 54, spring 73, protective tube 75, and retaining ring 74 are coaxially arranged. One end of the fiber optic cable 54 passes through the protective tube 75 and the ferrule tail 72 and is housed in the fiber optic ferrule 60. One end of the ferrule is housed in the ferrule tail 72, and the other end protrudes from the ferrule tail 72 for easy insertion into the fiber optic sleeve 22. One end of the spring 73 is fitted onto the ferrule tail 72 and abuts against it, while the other end is fitted into the protective tube 75. Both the spring 73 and the protective tube 75 are housed in the rear housing 71, and the other end of the spring 73 abuts against the inner wall of the rear housing 71.

[0053] Please see Figure 10When assembling connector 300, firstly, the fiber optic ferrule 60, ferrule tail 72, spring 73, and protective tube 75 are coaxially arranged and housed in the rear housing 71, which is housed in the second housing 40. Then, the retaining ring 74 is fitted onto the rear housing 71. First, one end of the fiber optic cable 54 is fixed to the main body 52, and the other end of the fiber optic cable 54 is passed through the protective tube 75 and the ferrule tail 72 and housed in the fiber optic ferrule 60. Then, the wire 56 is inserted into the wire groove 433, and the protrusion 4332 on the wire groove 433 is engaged in the retaining groove 562 on the wire 56. The end of the wire 56 is exposed in the second housing 42. Finally, the sheath 76 is fitted onto the optoelectronic hybrid cable 50 formed by the fiber optic cable 54, the wire 56, and the main body 52, and the sheath 76. The sheath 76 is pushed so that the rear housing 71 abuts against the spring 73, and the rear housing 71 is engaged in the second housing 40, thereby completing the assembly of connector 300.

[0054] Please see Figure 11 When the connector 300 is inserted into the adapter 200, one end of the second housing 40 is inserted into the first housing 10, and the end of the wire 56 first abuts against the second conductive part 36 of the conductive member 30 to achieve electrical connection. As the second housing 40 further enters the first housing 10, the end of the wire 56 causes the second conductive part 36 to deform towards the blocking part 14, so that the wire 56 and the conductive member 30 are interference-fitted, until the second housing 40 is inserted into the expected position. At this time, the first end face 424 of the second housing part 42 can abut against the surface of the blocking part 14; the fiber optic ferrule 60 is inserted into the fiber optic sleeve 22, and the protrusion 442 on the pressing part 44 and the retaining part 18 are mutually engaged, thereby connecting the connector 300 and the adapter 200 into a whole.

[0055] When it is necessary to disassemble the connector 300 and the adapter 200, press the pressing part 44 to release the limiting effect of the retaining part 18 on the protrusion 442, and remove the second housing 40 from the first housing 10 to separate the connector 300 and the adapter 200.

[0056] The adapter 200 and connector 300 provided in this application embodiment have a structure in which the end of the wire 56 abuts against the conductive element 30, causing the conductive element 30 to deform, thereby making the wire 56 and the conductive element 30 interference fit, thus realizing the connection of electrical signals between the adapter 200 and the connector 300. The overall structure is simple to assemble and reduces costs.

[0057] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
