Description

Technical Field

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

[0002] HDMI (High Definition Multimedia Interface) is a connector interface for displays. The connector interface includes a board-side connector and a wire-side connector. The board-side connector has a mating cavity and two rows of terminals located in the mating cavity. Furthermore, board-side connectors mostly use metal wires for signal transmission.

[0003] Because HDMI interface connectors mostly use metal wires for signal transmission, the transmitted signal will attenuate as the cable length increases. For example, when the cable length exceeds 10 meters, it can even seriously affect picture and sound quality. Furthermore, due to the mating cavity design of the HDMI interface board connector, poor contact may occur after years of use. Utility Model Content

Detailed Implementation

[0029] In some embodiments of this case, "signal" refers to light, image, sound, and other signals that the fiber optic connector can transmit.

[0030] In some embodiments of this application, "optical fiber" or "optical fiber" refers to a fiber made of glass or plastic, used in optical transmission tools that utilize the principle of total internal reflection to transmit light. In some embodiments of this application, "optical fiber cable" refers to a cable or wire containing optical fibers. In some embodiments of this application, "optical fiber module" refers to a module structure containing optical fibers.

[0031] Please see Figures 1 to 4This is one embodiment of a fiber optic connector 100. The fiber optic connector 100 is a connector for wire ends and a connector for mating board ends, used for signal transmission in a display. The fiber optic connector 100 includes a body 10, a top cover 80, a circuit board 20, a plurality of terminals 30, a first buffer 40, a fiber optic module 50, a plurality of magnetic attractors 60, and wires 70. The body 10 has an accommodating space A. The top cover 80 includes a through hole 81. The body 10 is coupled to the top cover 80. The circuit board 20 is disposed in the accommodating space A. The first buffer 40 is disposed on the circuit board 20. The fiber optic module 50 is disposed on the first buffer 40 and corresponds to the through hole 81. The plurality of magnetic attractors 60 are disposed on the circuit board 20 and adjacent to the top cover 80. The wires 70 include a plurality of power transmission lines 71 and a plurality of fiber optic cables 73. Each power transmission line 71 is connected to the circuit board 20 and electrically connected to each terminal 30, and each fiber optic cable 73 is connected to the fiber optic module 50. Please refer to [link to relevant documentation]. Figure 7 The circuit board 20 includes a plurality of contacts 21, and a plurality of terminals 30 are disposed on the circuit board 20 and connected to each contact 21. (See also...) Figure 10 The first surface 51 of the fiber optic module 50 protrudes from the outer surface 82 of the upper cover 80. The first buffer 40 provides cushioning between the fiber optic module 50 and the circuit board 20, and absorbs assembly tolerances of the fiber optic connector 100. Furthermore, through the magnetic suction member 60, the fiber optic connector 100 can be magnetically attached and positioned with other connectors (e.g., board-end connectors), thus avoiding potential contact problems that may arise between the fiber optic connector 100 and its corresponding connectors over long-term use. Moreover, through the fiber optic cable 73 and the fiber optic module 50, the signal input to the fiber optic connector 100 can be transmitted through optical fibers, enabling the fiber optic connector 100 to perform long-distance lossless signal transmission exceeding ten meters. In some embodiments, the fiber optic connector 100 can perform long-distance lossless signal transmission exceeding fifteen meters.

[0032] Please see Figures 2 to 4 In some embodiments, when the fiber optic connector 100 mates with a board-side connector on the display, the terminals 30 of the fiber optic connector 100 come into contact with the contacts of the board-side connector. Here, current is transmitted from the power transmission line 71 of the fiber optic connector 100 to the terminals 30 of the fiber optic connector 100, and then to the contacts of the board-side connector that are in contact with the terminals 30 of the fiber optic connector 100, providing power to the board-side connector.
