Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to an optical fiber connector. Background Technology

[0002] Traditional connectors use copper as the conductor for electronic signal transmission. The faster the signal transmission speed, the more susceptible it is to interference from external signals and the environment. Currently, the physical transmission speed using copper as the conductor is nearing its limit, necessitating the use of fiber optic connectors that utilize light as the medium to continue connector development. Furthermore, using copper conductors for signal transmission and power supply is prone to mutual interference, requiring special planning and handling for signal and power integrity. While fiber optic connectors can increase signal transmission speed, they cannot simultaneously provide an effective and sufficient power supply. Utility Model Content

The wire connector 200 is inserted into the board connector 100 in the forward direction to transmit a first signal, and can also be inserted into the board connector 100 in the reverse direction to transmit a second signal. The transmission specifications of the first signal conform to the transmission specifications of the second signal. It has the function of allowing the wire end connector 200 to be inserted into the board end connector 100 for signal transmission without being restricted to either the forward or reverse direction.

There is one slot 62, and viewed inward from the mating frame 61, the slot 62 is located on the right side. The mating frame 61 communicates with the slot 62. The line optical communication module 8 is disposed in the mating frame 61 and located on the side of the slot 62.

[0040] Please see Figures 14 to 17In some embodiments, the plurality of first plug power terminals 712 of the line connector 200' includes three first rows of elastic contacts 7121 located on the side of the line optical communication module 8, and the plurality of second plug power terminals 722 includes three second rows of elastic contacts 7221 located on the side of the line optical communication module 8. The number of the plurality of first plug power terminals 712 and the plurality of second plug power terminals 722 can be six or more (e.g., eight or more). In addition, each first row of elastic contacts 7121 defines a first axis 7121a extending toward the second plate 64, and each second row of elastic contacts 7221 defines a second axis 7221a extending toward the first plate 63. The first axis 7121a and the second axis 7221a are staggered with each other, and the upper and lower rows of terminals are staggered to facilitate the injection molding of each terminal in one step. Furthermore, the first axis 7121a of the first row of elastic contact portions 7121 overlaps with the first axis 31a of the first row of flat contact portions 31, and the second axis 7221a of the second row of elastic contact portions 7221 overlaps with the second axis 32a of the second row of flat contact portions 32. Additionally, the overall width of the first plate 63 and the second plate 64 changes relative to the number of terminals; the more terminals, the wider the overall width of the first plate 63 and the second plate 64.

[0041] When the wire-end connector 200' is inserted into the board-end connector 100', the wire-end housing 5 is inserted into the receiving space 12 through the insertion frame opening 11 of the board-end housing 1, and the tongue plates 22 are respectively inserted into the slots 62, so that the wire-end connector 200' and the board-end connector 100' can be mated together. Then, the first row of elastic contact portions 7121 of the first plug power terminal 712 contacts the first row of flat contact portions 31, and the second row of elastic contact portions 7221 of the second plug power terminal 722 contacts the second row of flat contact portions 32. Next, the board-end optical communication module 4 connects to the wire-end optical communication module 8, and the optical fiber signal is transmitted between the optical fiber line connected to the board-end optical communication module 4 and the optical fiber line connected to the wire-end optical communication module 8.

[0042] Please see Figures 18 to 19 , Figure 18 This is a schematic diagram showing the appearance of the board-end connector 100'' and the line-end connector 200'' of the fiber optic connector. Figure 19 Illustration as follows Figure 12 A cross-sectional view. In some embodiments, the board-end connector 100'' includes a tongue 22 extending outward from the side of the base 21. Viewed from the insertion frame 11 toward the receiving space 12, the tongue 22 is located on the right side of the receiving space 12. The insulating body 2 has an assembly portion 23 penetrating the base 21 and adjacent to the tongue 22, the assembly portion 23 being located on the left side of the receiving space 12. The detailed structure of the board-end connector 100'' has been described above and will not be repeated here.

[0043] Please see Figures 18 to 19 In some embodiments, the insulating body 6 of the wire connector 200'' includes a slot 62 located between the first plate 63 and the second plate 64, and a mating frame 61. There is one slot 62, and viewed inward from the mating frame 61, the slot 62 is located on the left side, with the mating frame 61 communicating with the slot 62. The wire-end optical communication module 8 is disposed in the mating frame 61 and located on the side of the slot 62. The detailed structure of the wire connector 200'' has been described above and will not be repeated here.

[0044] In summary, according to some embodiments, a board-end connector for fiber optic connectors is constructed by setting a base and a tongue plate within an insulating body inside the board-end housing, with one end of each socket power terminal arranged on both sides of the tongue plate. Furthermore, the number of socket power terminals of the board-end connector can be increased as needed.
