[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0044] Example 1

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the optoelectronic hybrid connector plug is used in conjunction with a socket, the socket includes a socket housing 60, and the socket housing 60 is equipped with a socket contact 61. The plug includes

[0046] The plug housing 10 is set to be rectangular and is made of 316 stainless steel, so that the plug has strong corrosion resistance and salt spray resistance;

[0047] An upper base 20, a lower base 30 and a sealing body 40 are sequentially arranged inside the plug housing 10 in a first direction, and the first direction is a direction from the plug end to the mounting end of the connector;

[0048] The plug contact 50 is assembled to the upper base 20, the lower base 30 and the sealing body 40, and the plug end of the plug contact 50 is provided with a round hole matching the plug end of the socket contact 61; when the plug and the socket are plugged in, the plug contact 50 contacts the socket contact 61, and the plug end of the socket contact 61 is inserted into the inside of the round hole;

[0049] The plug contact 50 includes one fiber optic contact 51 distributed at the center, four electrical contacts 52 distributed in a matrix with the fiber optic contact 51 as the center, and ten electrical contacts 53 distributed in a matrix with the fiber optic contact 51 as the center on the outside of the electrical contact 52; the fiber optic contact 51 is a 16# fiber optic contact, the electrical contact 52 is a 22D# electrical contact, and the electrical contact 53 is a 12# electrical contact.

[0050] In the technical solution, the upper base 20, the lower base 30, and the sealing body 40 are sequentially arranged inside the plug housing 10 in the first direction, and the optical fiber contact 51, the electrical contact 1 52, and the electrical contact 2 53 penetrate the upper base 20, the lower base 30, and the sealing body 40, so that the optoelectronic hybrid connector plug in the technical solution integrates light and electricity, and the optical signal and the electrical signal are synchronously connected;

[0051] Among them, the plug contact 50 includes one optical fiber contact 51 distributed in the center, four electrical contacts 52 distributed in a matrix with the optical fiber contact 51 as the center, and ten electrical contacts 53 distributed in a matrix with the optical fiber contact 51 as the center on the outside of the electrical contact 52. The optical fiber contact 51 is a 16# optical fiber contact, the electrical contact 52 is a 22D# electrical contact, and the electrical contact 53 is a 12# electrical contact. This makes the optoelectronic hybrid connector plug in the present technical solution have the characteristics of simultaneously transmitting optical signals and electrical signals. At the same time, the plug shell 10 is set to a rectangle. Combined with the position distribution of the optical fiber contact 51, the electrical contact 52, and the electrical contact 53, the internal structure of the optoelectronic hybrid connector plug in the present technical solution is reasonably distributed and highly integrated, so that the plug has a small appearance and meets the needs of miniaturization of the optoelectronic connector.

[0052] In order to improve the position stability of the optical fiber contact 51, the first electrical contact 52, and the second electrical contact 53 after being assembled into the plug housing 10, as shown in FIG. Figure 2 As shown, the optical fiber contact 51 is provided with a support spring ring 511, the electrical contact 52 is provided with a support spring ring 521, and the electrical contact 53 is provided with a support spring ring 531; the support spring ring 511, the support spring ring 521 and the support spring ring 531 are assembled inside the lower base 30 and the sealing body 40.

[0053] The arrangement of the support spring ring 1 511, the support spring ring 2 521 and the support spring ring 3 531 provides appropriate pressure for the optical fiber contact 51, the electrical contact 1 52 and the electrical contact 2 53, so that they will not rotate freely or loosen and can be safely assembled into the plug; at the same time, the arrangement of the support spring ring 1 511, the support spring ring 2 521 and the support spring ring 3 531 can precisely control the contact pressure between the pin and the plug, thereby ensuring the stability of the electrical performance of the connector.

[0054] To meet the installation requirements of the optical fiber contact 51, the electrical contact 1 52, and the electrical contact 2 53, as shown in FIG. Figure 7 As shown, the upper base 20 is provided with a hole A-21 matching the optical fiber contact 51, a hole B-22 matching the electrical contact 1 52, and a hole C-23 matching the electrical contact 2 53;

[0055] like Figure 8 As shown, the lower base 30 is provided with a hole A231 matching the optical fiber contact 51, a hole B232 matching the electrical contact 1 52, and a hole C233 matching the electrical contact 2 53;

[0056] like Fig. 9 As shown, the sealing body 40 is provided with a hole A3 41 matching the optical fiber contact 51 , a hole B3 42 matching the electrical contact 1 52 , and a hole C3 43 matching the electrical contact 2 53 .

[0057] When assembling the optical fiber contact 51, the optical fiber contact 51 passes through the hole A-21, the hole A-31, and the hole A-3 41 in sequence; when assembling the electrical contact 52, the electrical contact 52 passes through the hole B-22, the hole B-32, and the hole B-3 42 in sequence; when assembling the electrical contact 53, the electrical contact 53 passes through the hole C-23, the hole C-33, and the hole C-3 43 in sequence.

[0058] To realize the arrangement that the base 20, the lower base 30, and the sealing body 40 are assembled inside the plug housing 10, as shown in FIG. Figure 5 , Figure 6 , Figure 7 As shown, the plug housing 10 has an installation cavity 11 for accommodating the upper base 20, the lower base 30, and the sealing body 40, and a limiting step surface 111 is arranged inside the installation cavity 11; the upper base 20 has a limiting step surface 24, and when the upper base 20 is assembled into the installation cavity 11, the limiting step surface 111 conflicts with the limiting step surface 24, thereby limiting the position of the upper base 20, the lower base 30, and the sealing body 40 at the plug-in end inside the installation cavity 11.

[0059] like Figure 6As shown, a glue pouring groove 112 for pouring glue is provided on the inner wall of the installation cavity 11, and the glue pouring groove 112 is located at the position of the sealing body 40. After the upper base 20, the lower base 30, and the sealing body 40 are assembled inside the installation cavity 11, the glue pouring operation is performed into the installation cavity 11 through the glue pouring groove 112, and the sealing performance of the plug housing 10 is ensured by the sealing cooperation between the sealing body 40 and the plug housing 10.

[0060] In order to achieve accurate assembly of the upper base 20, the lower base 30 and the sealing body 40 inside the installation cavity 11, as shown in FIG. Figure 7 , Figure 8 , Fig. 9 As shown, a small fillet 113 and a large fillet 114 are provided at the inner corners of the installation cavity 11 , and fillets matching the small fillet 113 and the large fillet 114 are provided on the upper base 20 , the lower base 30 and the sealing body 40 .

[0061] When the upper base 20, the lower base 30 and the sealing body 40 are assembled into the installation cavity 11, the rounded corners of the upper base 20, the lower base 30 and the sealing body 40 correspond to the small rounded corners 113 and the large rounded corners 114 inside the installation cavity 11, so that the plug has an anti-foolproof function during the assembly process, thereby achieving precise assembly of the upper base 20, the lower base 30 and the sealing body 40 inside the installation cavity 11.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the outer wall of the plug housing 10 extends radially outward to form a docking step 13, and a mounting hole 131 is provided on the docking step 13. A guide column 132 is assembled in the mounting hole 131; the outer wall of the socket housing 60 extends radially outward to form a docking step 2 62, and a guide hole 621 matching the guide column 132 is provided on the docking step 2 62.

[0063] When the plug and the socket are plugged in, the docking step 13 and the docking step 2 62 are in contact with each other to limit the plug-in end position of the plug and the socket; the guide column 132 is inserted into the guide hole 621 to play a guiding role during the plug-in process, thereby improving the convenience of the plug-in process.

[0064] Further, for Figure 1 , Figure 2 As shown, the guide column 132 in this embodiment can be set to two with different thicknesses, so that when the plug and the socket are plugged in and matched, they have the functions of blind plugging and preventing wrong plugging.

[0065] To meet the requirement of fixed plug installation position, such as Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 As shown, the outer wall of the plug housing 10 extends radially outward to form a flange surface 14, and a plurality of mounting holes 141 are provided on the flange surface 14 for flange connection with an external object. A floating rivet tube 142 is provided in the mounting hole 141, so that the plug has a floating function during the installation process, thereby solving the problem of errors in the installation position.

[0066] In order to improve the convenience of assembling the guide column 132 into the interior of the mounting hole 131, as shown in FIG. Figure 6 As shown, the docking step 13 is connected to the flange surface 14, and the mounting hole 131 passes through the flange surface 14. The mounting hole 131 is located at the end of the flange surface 14 and is provided with a chamfer 1311. When the guide column 132 is assembled to the mounting hole 131, it is inserted from the end with the chamfer 1311.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
