These are the fundamental requirements of a fiber optic connector. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Fiber optic connectors can be categorized by transmission medium, including single-mode and multimode connectors for common silica-based optical fibers, as well as other types using plastic as transmission media. Fiber optic connectors can be categorized by connector structure, including FC, SC, ST, LC, D4, DIN, MU, and MT. ST connectors are commonly used on wiring equipment, such as fiber distribution frames and fiber modules, while SC and MT connectors are commonly used on network equipment. Fiber optic connectors are categorized by end face shape into FC, PC (including SPC or UPC), and APC. Fiber optic connectors can be categorized by the number of fiber cores, including single-core and multi-core (such as MT-RJ). Fiber optic connectors are widely used and come in a wide variety of varieties.

[0031] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present utility model, including an insulating base 10, a front cover 20, a rear cover 30 and a light emitting device 40.

[0032] The front end of the insulating base 10 is recessed with an insertion cavity 11 for receiving a plug, and the rear end of the insulating base 10 is recessed with a mounting cavity 12. The mounting cavity 12 communicates with the insertion cavity 11 via a plug hole 13, which is adapted to mate with the input terminal of the plug. In this embodiment, the top of the front end of the insertion cavity 11 is provided with upwardly facing hinge slots 14 on both sides.

[0033] The front cover 20 is mounted on the front end of the insulating base 10 so that it can be flipped up and down to open or close. When the front cover 20 is flipped up, the front opening of the insertion cavity 11 is opened, and when the front cover 20 is flipped down, the front opening of the insertion cavity 11 is closed. In this embodiment, hinge shafts 21 extend from the top and left sides of the front cover 20. The two hinge shafts 21 are hingedly inserted into the hinge grooves 14 from top to bottom. In addition, a groove 22 is recessed on the inner top of the front cover 20.

[0034] The rear cover 30 is disposed at the rear end of the insulating base 10 and covers the rear end opening of the mounting cavity 12. In this embodiment, the rear cover 30 is embedded in the rear end opening of the mounting cavity 12 and is snap-fitted to the insulating base 10, resulting in a simple structure and easy assembly.

[0035] The light emitting device 40 is disposed in the mounting cavity 12 and faces the insertion hole 13. The light emitting device 40 has a plurality of solder pins 41 extending out of the insulating base 10. In this embodiment, the plurality of solder pins 41 are arranged side by side and spaced apart and extend vertically downward from the bottom of the insulating base 10 to facilitate soldering and electrical connection to an external circuit board.

[0036] Furthermore, the insulating base 10 is provided with a housing 50, with fixing legs 51 extending downward from both sides of the housing 50. The housing 50 is in an inverted U-shape, fitting over the insulating base 10 from top to bottom and being securely fastened thereto. Two blocking portions 52 extend forward from the front of the housing 50, covering the upper openings of the hinge slots 14 to prevent the hinge shaft 21 of the front cover 20 from falling out. The housing 50 is made of stamped iron.

[0037] In addition, a spring-pressing piece 60 is provided at the inner top of the insertion cavity 11 for causing the front cover 20 to flip downward. The front end of the spring-pressing piece 60 has a spring-pressing portion 61, and the front end of the spring-pressing portion 61 is embedded in the groove 22. The structure is simple and easy to assemble, and the front cover 20 can automatically flip down to close the front end opening of the insertion cavity 11.

[0038] The assembly process of this embodiment is described in detail as follows:

[0039] First, embed the light-emitting device 40 into the mounting cavity 12 from back to front, then embed the back cover 30 into the rear end opening of the mounting cavity 12 from back to front, and snap-fit the back cover 30 to the insulating base 10; then, embed the two hinge shafts 21 of the front cover 20 into the hinge groove 14 from top to bottom and hinge them, finally, fit the outer shell 50 from top to bottom onto the outside of the insulating base 10 and snap-fit and fix it to the insulating base 10.

[0040] During use, the product is fixed to a circuit board and the multiple solder pins 41 are soldered to the circuit board. Next, the front cover 20 is manually flipped upward to open, and the fiber optic plug is inserted into the insertion cavity 11. Once fully inserted, the input end of the fiber optic plug is inserted into the insertion hole 13 and faces the light emitting device 40. When the light emitting device 40 is powered, the optical fiber generated by the light emitting device 40 enters the optical fiber and is transmitted outward through the optical fiber. When the fiber optic plug is removed, the front cover 20 automatically flips downward under the action of the spring plate 60 to cover the front opening of the insertion cavity 11, preventing foreign matter from entering the insertion cavity 11.

[0041] The design focus of the utility model is that the front cover is arranged at the front end of the insulating base so that it can be flipped up and down to open or close. When not in use, the front cover can cover the opening of the insertion cavity to prevent external dust and other foreign matter from invading the insertion cavity. At the same time, the insertion hole is adapted to be plugged into the input end of the plug, which is conducive to ensuring the speed and efficiency of light transmission and bringing convenience to use. At the same time, the rear cover is provided to make the installation of the light-emitting device easier.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
