[0004] Optical fiber cables are used to transmit both optical and electrical signals. They are flat and consist of an optical fiber and a pair of conductors. The optical fiber is located in the center, with the conductors flanking it. Both the optical fiber and the conductors are protected by a flexible insulating coating. After the optical fiber and conductors are aligned, they are encapsulated in a protective sheath.

[0005] When assembling an optical fiber composite cable with a fiber optic connector, first remove the protective cover at the location where the optical fiber composite cable needs to be connected to the connector, and then connect the optical fiber and conductor to the connector separately. When connecting, you need to first remove the conductor's coating, and then use welding to connect the conductor's core to the conductive piece of the fiber optic connector. Summary of the Invention

[0063] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "connection" should be understood as an electrical connection, optical connection or wireless connection with communication function.

[0064] When assembling an optoelectronic composite cable and connector, the protective covering must first be removed from the connector connection area. The optical fiber and conductor are then connected to the connector separately. The conductor's coating must first be removed, and then the core of the conductor must be soldered to the conductive sheet of the optical fiber connector. This operation is cumbersome and unsuitable for on-site installation. The optoelectronic composite connector and cable present inconvenience in on-site installation.

[0065] The embodiments of the present application provide an optoelectronic composite connector and an adapter. To make the purpose, technical solution and advantages of the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and examples.

[0066] An embodiment of the present application provides an optoelectronic composite connector, which may be a Lucent Connector type optical fiber connector that can be quickly installed on site. Figure 1 is a schematic structural diagram of an optoelectronic composite connector in one embodiment of the present application. Figure 2 is a schematic structural diagram of a conductive sheet in one embodiment of the present application. Figure 3 is a schematic structural diagram of an optoelectronic composite connector in another embodiment of the present application. Figure 4 is a side sectional view of an optoelectronic composite connector in one embodiment of the present application. In conjunction with Figures 1 to 4, the optoelectronic composite connector includes a first shell 1, a second shell 2 and a conductive sheet 3. The first shell 1 has a receiving groove 11 and a through groove 12 extending along a first direction M, respectively. The receiving groove 11 is used to accommodate the first conductor 101 of the optoelectronic composite cable 100, and the through groove 12 is used to accommodate the optical fiber 102 of the optoelectronic composite cable 100. The through groove 12 has a channel, and the optical fiber 102 is passed through the channel. The conductive sheet 3 includes a connecting portion 31 located at the bottom of the receiving slot 11. The connecting portion 31 includes at least one sharp tip 311, which is configured to pierce the coating of the first conductor 101 and contact the first conductor 101. The second housing 2 is mounted on the first housing 1 by rotation about a second direction N, which is perpendicular to the first direction M. The second housing 2 includes a top plate 21 and side plates 22 that are interconnected. When the second housing 2 rotates to the first position, the side plates 22 extend into the receiving slot 11 and push (i.e., squeeze) the first conductor 101 toward the sharp tip 311.

[0067] In the above embodiment, the conductive sheet 3 is fixedly mounted to the first housing 1, with the connecting portion 31 located at the bottom of the receiving groove 11 and the tip 311 facing the opening of the receiving groove 11. During on-site assembly of the optoelectronic composite connector and the optoelectronic composite cable 100, the first conductor 101 is placed above the tip 311, the optical fiber 102 is placed in the channel of the through groove 12, and finally, the second housing 2 is rotated to cover the first housing 1. The side panels 22 of the second housing 2 extend into the receiving groove 11 and continuously compress the space within the receiving groove 11, pushing the first conductor 101 closer to the tip 311 of the conductive sheet 3, thereby piercing the coating and causing the tip 311 to contact the first conductor 101, thereby achieving electrical connection between the first conductor 101 and the conductive sheet 3. When the second housing 2 is rotated to the first position, the second housing 2 is fully installed. The optoelectronic composite connector of the present application can be assembled with the optoelectronic composite cable 100 without the use of any tools, making installation convenient and quick, thereby improving efficiency.

[0068] In one embodiment, the through slot 12 includes a top wall 121, which is located on the side of the through slot 12 facing away from the first housing 1. When the second housing 2 rotates to the first position, the top plate 21 abuts against the top wall 121. The top wall 121 of the through slot 12 serves to limit the position of the second housing 2, preventing the second housing 2 from squeezing and damaging the first conductor 101 due to excessive rotation.

[0069] In one embodiment, the above-mentioned receiving groove 11 includes a first receiving groove 111 and a second receiving groove 112, and the through groove 12 is located between the first receiving groove 111 and the second receiving groove 112. Specifically, the through groove 12 is located in the middle of the receiving groove 11, dividing the receiving groove 11 into two parts, forming the first receiving groove 111 and the second receiving groove 112. A conductive sheet 3 is also installed in the second receiving groove 112, and the tip 311 of its connecting portion 31 is located at the bottom of the second receiving groove 112. The optoelectronic composite cable 100 also includes a second conductor 103, wherein the first conductor 101 is located in the first receiving groove 111, and the second conductor 103 is located in the second receiving groove 112. Correspondingly, the above-mentioned side panel 22 includes a first side panel 221 and a second side panel 222 arranged opposite to each other along the second direction N, and the first side panel 221 and the second side panel 222 are respectively connected to the top panel 21, so that the second shell 2 is C-shaped. When the second shell 2 is covered, the first side plate 221 extends into the first receiving groove 111 to squeeze the first conductor 101, and the second side plate 222 extends into the second receiving groove 112 to squeeze the second conductor 103, so that the first conductor 101 and the second conductor 103 are respectively close to the tip 311, and finally their coatings are pierced by the tip 311, forming contact and conduction with the conductive sheet 3.

[0070] To ensure that the coatings of the first and second conductors 101, 103 can be punctured, in one embodiment, the width of the first receiving groove 111 can be equal to or slightly larger than the outer diameter of the coating of the first conductor 101, so that the first conductor 101 does not roll in the first receiving groove 111. The width of the second receiving groove 112 can be equal to or slightly larger than the outer diameter of the coating of the second conductor 103, so that the second conductor 103 does not roll in the second receiving groove 112. This effectively reduces the possibility that the first and second conductors 101, 103 may slip off the tip 311, resulting in the coating being unable to be effectively punctured.

[0071] In one embodiment, the first side panel 221 is provided with a first latch 2211, and the second side panel 222 is provided with a second latch 2221. The first latch 2211 is located on the side of the first side panel 221 facing away from the second side panel 222, and the second latch 2221 is located on the side of the second side panel 222 facing away from the first side panel 221. The first housing 1 includes a first side wall 13 and a second side wall 14 arranged opposite each other along a second direction N. The first side wall 13 is provided with a first latch 131, and the second side wall 14 is provided with a second latch 141. When the second housing 2 is rotated to the first position, the first latch 2211 is inserted into the first latch 131, and the second latch 2221 is inserted into the second latch 141, thereby achieving locking of the second housing 2 with the first housing 1.

[0072] In one embodiment, referring to Figures 3 and 4, a first clamping portion 23 is provided at one end of the second housing 2 away from its rotation center, and a second clamping portion 15 is provided at the end of the first housing 1. When the second housing 2 is in the first position, the second clamping portion 15 is opposite to the first clamping portion 23. The cross-sections of the first clamping portion 23 and the second clamping portion 15 are both C-shaped, and their openings are opposite. There is also a gap between the first clamping portion 23 and the second clamping portion 15, which allows the optical fiber 102, the first conductor 101, and the second conductor 103 to pass through. After the second housing 2 is closed, the first clamping portion 23 and the second clamping portion 15 do not contact each other, which allows the space between the first clamping portion 23 and the second clamping portion 15 to be larger. As a result, the first conductor 101 and the second conductor 103 can pass through the gap and directly extend into the first receiving groove 111 and the second receiving groove 112 without having to bypass the first clamping portion 23 and the second clamping portion 15, thereby reducing the stress generated by the first conductor 101 and the second conductor 103 being bent due to the need to bypass the first clamping portion 23 and the second clamping portion 15. The above-mentioned optoelectronic composite connector also includes a third shell 4, which is connected to the first clamping portion 23 and the second clamping portion 15. When the second shell 2 is in the first position, the first clamping portion 23 and the second clamping portion 15 are combined to form a cylindrical structure, which can be called a clamping joint. The third shell 4 is sleeved on the outer wall of the clamping joint to fix the third shell 4, the first shell 1 and the second shell 2, and to prevent the second shell 2 from opening accidentally.

[0073] To improve the reliability of the connection between the third housing 4 and the first and second clamping portions 23 and 15, referring to FIG4 , in one embodiment, at least one first ridge 231 spaced apart along the first direction M is provided on the side of the first clamping portion 23 facing away from the second clamping portion 15, and at least one second ridge 151 spaced apart along the first direction M is provided on the side of the second clamping portion 15 facing away from the first clamping portion 23. The inner wall of the third housing 4 has at least one annular groove 41 spaced apart along the first direction M. The first and second ridges 231 and 151 are positioned opposite each other and engage with the same groove 41, respectively. This prevents the third housing 4 from separating from the first and second housings 1 and 2. It is worth noting that the first ridge 231 can be provided not only on the side of the first clamping portion 23 facing away from the second clamping portion 15, but can also extend toward both sides of the second clamping portion 15. Similarly, the second ridges 151 may not only be provided on the side of the second clamping portion 15 facing away from the first clamping portion 23, but may also extend toward both sides of the second clamping portion 15 closer to the first clamping portion 23. This allows the outer wall of the clamping joint to be covered with ridges, that is, all four sides of the clamping joint are provided with ridges, thereby improving the reliability of the connection with the third housing 4.

[0074] Figure 5 is an exploded view of an optoelectronic composite connector according to one embodiment of the present application. In conjunction with Figures 1 to 5 , in one embodiment, the third housing 4 has a through hole through which the optoelectronic composite cable 100 is inserted. The third housing 4 is flexible, protecting the optoelectronic composite cable 100 from damage caused by stress and bending.

[0075] Figure 6 is a schematic diagram of the structure of a fourth housing in one embodiment of the present application, and Figure 7 is a schematic diagram of the structure of an optoelectronic composite connector in another embodiment of the present application. In conjunction with Figures 6 and 7, in one embodiment, the optoelectronic composite connector further comprises a fourth housing 5, which is mounted on the end of the first housing 1 facing away from the third housing 4. The fourth housing 5 is a sleeve structure that fits over the exterior of the first housing 1. The conductive sheet 3 is connected to the fourth housing 5. A mounting slot 51 is defined within the interior of the fourth housing 5, through which the conductive sheet 3 is inserted to secure it to the fourth housing 5. The conductive sheet 3 may be pre-attached to the fourth housing 5 at the factory, for example, by insert molding the two metal conductive sheets 3. The conductive sheet 3 includes a contact portion 32 located at the end of the conductive sheet 3 facing away from the connection portion 31. The outer wall of the fourth housing 5 has a relief hole 52, which allows the contact portion 32 to be exposed outside the fourth housing 5.

[0076] Figure 8 is an exploded view of a ferrule assembly in one embodiment of the present application. Figure 9 is a side cross-sectional view from another angle of an optoelectronic hybrid connector in one embodiment of the present application. In conjunction with Figures 5, 8, and 9, in one embodiment, the fourth housing 5 is a hollow structure. The optoelectronic hybrid connector also includes a ferrule assembly 6. The ferrule assembly 6 is partially installed within the inner cavity of the fourth housing 5, and the other portion is installed within the first housing 1. Specifically, the ferrule assembly 6 includes a ferrule body 61, a compression plate 62, and a sliding sleeve 63. The ferrule body 61 has a mounting groove 611 for accommodating the compression plate 62. The compression plate 62 is installed in the mounting groove 611, and the sliding sleeve 63 is disposed outside the ferrule body 61 and the compression plate 62. The sliding sleeve 63 is capable of sliding in a first direction M. The ferrule body 61 has a groove 612 for the optical fiber 102 to pass through. When the optical fiber 102 is laid in the groove 612, a portion of the optical fiber 102 is located outside the groove 612 along the radial direction of the groove 612. The compression piece 62 covers the groove 612. When the compression piece 62 moves toward the groove 612, the optical fiber 102 is compressed by the compression piece 62 and the ferrule body 61, reducing its radial movement. The sliding sleeve 63 is used to move the compression piece 62 closer to the groove 612 so that the compression piece 62 and the ferrule body 61 can clamp the optical fiber 102.

[0077] Figure 10 is a side cross-sectional view of an optoelectronic hybrid connector according to another embodiment of the present application. As shown in Figure 10, in one embodiment, the inner side of the sliding sleeve 63 has a stepped first surface, and the pressure plate 62 has a stepped second surface that matches the first surface. When the sliding sleeve 63 moves relative to the pressure plate 62 and the ferrule body 61, the first surface slides relative to the second surface, and the first and second surfaces are offset from each other. Specifically, the first surface includes a first guide surface 631, a second guide surface 632, and a third guide surface 633, which are sequentially connected along a first direction M. The first guide surface 631 is parallel to the third guide surface 633, and the first guide surface 631 and the third guide surface 633 each form an obtuse angle with the second guide surface 632.
