Description

Technical Field

[0001] This utility model relates to the field of indoor optical cable patch cord production technology, and more specifically, to a hot-melt quick-connect LC connector plug. Background Technology

[0002] Optical fiber connectors are interface components in optical fiber communication systems that connect optical cables to equipment to achieve efficient transmission of optical signals. They typically consist of a precision ceramic ferrule, a housing, and a coupling mechanism to ensure precise alignment of the fiber end faces to reduce signal loss. Common types include SC, LC, and FC, and they feature low insertion loss, high stability, and dustproof design. They are widely used in high-speed data transmission scenarios in data centers, telecommunications networks, and broadcasting systems.

[0003] Existing pluggable connectors exhibit significant differences in stability under different environments. In scenarios with large temperature fluctuations, metal components may experience poor contact due to thermal expansion and contraction, while plastic shells are prone to becoming brittle at low temperatures. High humidity environments may cause oxidation or a decrease in insulation performance, while dusty environments can easily lead to contamination of the ferrule. In industrial scenarios with frequent vibrations, the risk of mechanical structure loosening increases, and outdoor applications also need to address the issue of ultraviolet aging. Differences in the corrosion resistance of different materials can also affect long-term reliability, resulting in inconsistent performance of connectors under complex working conditions.

[0004] In summary, to improve the reliability of fiber optic connectors in complex environments, it is necessary to address the significant differences in stability of pluggable connectors under different conditions, so that various fiber optic connectors can maintain long-term stable signal transmission performance in different scenarios such as data centers, industrial sites, and outdoor base stations. Utility Model Content

[0005] The present invention provides a hot-melt quick-connect LC connector plug, which aims to solve the problem that the stability of existing pluggable connectors varies significantly under different environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot-melt quick-connect LC connector plug, including an LC housing, a ceramic pin installed at the right end of the LC housing, a connecting tube installed at the left end of the LC housing, a threaded groove provided on the outer side of the connecting tube, a metal tube sleeved on the outer side of the connecting tube, the metal tube being fixedly connected to the connecting tube through the threaded groove, a knob fixed at the left end of the metal tube, the knob being used to rotate the metal tube, the knob being ring-shaped, and a protective mechanism provided at the right end of the LC housing, the protective mechanism being used to protect the ceramic pin.

[0007] In a preferred embodiment, the protective mechanism includes a dustproof component, a pull-out component, a reset component, a push-button component, and a locking component. The dustproof component is used to protect the ceramic pin, the pull-out component is used to pull out the dustproof component, the reset component is used to drive the locking component to reset and rotate, and the push-button component is used to drive the reset component to rotate.

[0008] In a preferred embodiment, the dustproof component includes a slot opened at the right end of the LC housing, into which a dustproof cap is inserted.

[0009] In a preferred embodiment, the pull assembly includes a pull rod fixed to the right end of the dust cap, with a pull ball fixed to the end of the pull rod.

[0010] In a preferred embodiment, the reset assembly includes through slots extending through the upper and lower sides of the LC housing. A rotating shaft is embedded in the inner side of each through slot, and a torsion spring is sleeved on the outer side of the rotating shaft. The rotating shaft is rotatably connected to the through slot through the torsion spring.

[0011] In a preferred embodiment, the pressing component includes a rotating plate fixed between two corresponding rotating shafts, and an anti-slip pad is provided on the outer side of the rotating plate.

[0012] In a preferred embodiment, the locking assembly includes a locking block fixed to the rotating plate, and the outer side of the dust cap is provided with a locking slot corresponding to the position of the locking block.

[0013] The beneficial effects of this utility model are as follows: This invention solves the problem of fiber optic connectors easily detaching when connected to optical fibers by fixing one end of the plug core inside the LC housing to the other end of the optical fiber core in a hot-melt machine. This ensures that the fiber cores at both ends are on the same horizontal line and can be tightly fused together. The integration of optical fiber and optical connector ensures that the optical patch cord can still operate stably in harsh environments. At the same time, a metal tube is added, and the metal tube and the LC plug are assembled in a spiral manner to ensure the stability and safety of the optical fiber splice.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual appendix Figures 1 to 5 A hot-melt quick-connect LC connector plug includes an LC housing 1, a ceramic pin 2 installed on the right end of the LC housing 1, a connecting tube 3 installed on the left end of the LC housing 1, a threaded groove 4 on the outer side of the connecting tube 3, a metal tube 5 sleeved on the outer side of the connecting tube 3, the metal tube 5 being fixedly connected to the connecting tube 3 through the threaded groove 4, a knob 6 fixed on the left end of the metal tube 5, the knob 6 being used to rotate the metal tube 5, the knob 6 being ring-shaped, and a protective mechanism provided on the right end of the LC housing 1, the protective mechanism being used to protect the ceramic pin 2.

[0022] It should be noted that when using the product, first unscrew the metal tube 5, peel off the sheath of the fiber inside to expose the fiber core, peel off the sheath of the fiber end that needs to be connected to the connector inside the LC housing 1 to expose the fiber core, and then heat fuse the two fiber cores together to form a whole using a heat fusion machine. Then, install the metal tube 5 on the connector tube 3 for protection. Finally, when using the product, simply open the protective mechanism to plug and unplug it. The heat fusion method effectively combines the connector and the fiber into a whole.

[0023] Refer to the instruction manual appendix Figures 1 to 5 The protective mechanism includes a dustproof component, a pull-out component, a reset component, a push-button component, and a locking component. The dustproof component is used to protect the ceramic pin 2, the pull-out component is used to pull out the dustproof component, the reset component is used to drive the locking component to reset and rotate, and the push-button component is used to drive the reset component to rotate.

[0024] It should be noted that when the dustproof component is inserted, the locking component can position the dustproof component. When the dustproof component needs to be removed, the locking component can be rotated by pressing the component to release the restriction on the dustproof component.

[0025] Refer to the instruction manual appendix Figure 2 and Figure 5The dustproof component includes a slot 710 located at the right end of the LC housing 1, into which a dustproof cap 71 is inserted.

[0026] It should be noted that by setting the slot 710, the dust cap 71 can be directly inserted into the slot 710 to protect the ceramic pin 2.

[0027] Refer to the instruction manual appendix Figure 2 and Figure 5 The pull assembly includes a pull rod 72 fixed to the right end of the dust cap 71, and a pull ball 711 is fixed to the end of the pull rod 72.

[0028] It should be noted that the dust cap 71 can be pulled out of the slot 710 by pulling the lever 72.

[0029] Refer to the instruction manual appendix Figure 2 and Figure 4 The reset assembly includes through slots 73 that extend through the upper and lower sides of the LC housing 1. A rotating shaft 74 is embedded in the inner side of each of the two through slots 73. A torsion spring 75 is sleeved on the outer side of the rotating shaft 74. The rotating shaft 74 is rotatably connected to the through slot 73 through the torsion spring 75.

[0030] It should be noted that when the shaft 74 rotates, the torsion spring 75 will twist and store energy.

[0031] Refer to the instruction manual appendix Figure 4 The push-button assembly includes a rotating plate 76 fixed between two corresponding rotating shafts 74, and an anti-slip pad 77 is provided on the outer side of the rotating plate 76.

[0032] It should be noted that pressing down on the anti-slip mat 77 with your fingers can cause the rotating plate 76 to rotate in conjunction with the rotating shaft 74.

[0033] Refer to the instruction manual appendix Figures 2 to 5 The locking assembly includes a locking block 78 fixed on the rotating plate 76, and a locking groove 79 is provided on the outer side of the dust cap 71 corresponding to the position of the locking block 78.

[0034] It should be noted that when the rotating plate 76 rotates, it can drive the locking block 78 to disengage from the slot 79, thereby releasing the restriction on the dust cap 71. When the dust cap 71 is inserted, the left end of the dust cap 71 contacts the inclined side of the locking block 78, which causes the locking block 78 to drive the rotating plate 76 to deflect outward. When the locking block 78 is flush with the slot 79, the torsion spring 75 releases its elastic restoring force, thereby locking the locking block 78 into the slot 79 and positioning the dust cap 71.

[0035] Working principle: First, unscrew the metal tube 5, peel off the fiber sheath to expose the fiber core, and fuse the fiber core to be connected with the fiber core inside the connector of the LC housing 1 using a hot melt machine. Then, reinstall the metal tube 5 and tighten it along the threaded groove 4 of the connector tube 3 using the knob 6 on its left end. When in use, press down on the anti-slip pad 77 on the outside of the rotating plate 76, which will cause the rotating plate 76 and the locking block 78 fixed on it to rotate and disengage from the slot 79 of the dust cap 71. At the same time, the rotating shaft 74 compresses the torsion spring. 75 stores energy. At this time, pulling the lever 72 and the ball 711 on the right end of the dust cap 71 will remove the dust cap 71. Then, the torsion spring 75 drives the rotating shaft 74 to rotate, so that the rotating plate 76 is reset. At the same time, the ceramic pin 2 is exposed for insertion and removal. When the dust cap 71 is inserted, its end contacts the inclined side of the locking block 78, which pushes the rotating plate 76 to rotate outward, so that the torsion spring 75 stores energy. After the locking block 78 is aligned with the slot 79, the torsion spring 75 releases its elastic force to drive the locking block 78 to lock into the slot 79 and lock the dust cap 71.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
