A quick insertion type optical fiber connector locking mechanism

Abstract

This utility model discloses a quick-connect fiber optic connector locking mechanism, including an optical fiber, one end of which is fitted with a connector, and a protruding tube fixedly connected to the front end of the optical fiber. This quick-connect fiber optic connector locking mechanism uses a spring-loaded latch to engage with the slot of the connector, simultaneously inserting the output guide rod at the front end of the plug into the slot for conduction. The rear tube at the front end of the protruding tube is threadedly connected to the front tube of the connector. The front tube is aligned with the connector and rotated, and the rotated front tube is threadedly fixed to the inner wall of the connector, thus securing the connector and connector together. A first guide tube installed at the end of the optical fiber, in conjunction with a second guide tube, connects to the second plug assembly for conduction, transmitting multiple signal lines into the first guide tube.

[0002] With the continuous development and popularization of fiber optic communication networks, fiber optic connectors, as key components in fiber optic communication systems, face increasingly stringent performance requirements. Traditional fiber optic connectors typically require specialized tools and skills for connection, resulting in complex and inefficient operations that cannot meet the demands of rapid deployment and maintenance.

[0003] In recent years, to meet the needs of rapid deployment and maintenance of fiber optic networks, some quick-connect fiber optic connectors have emerged on the market. These connectors achieve rapid insertion and removal by simplifying the connection process. However, existing quick-connect fiber optic connectors still have some problems in actual use, such as complex locking mechanism design, inconvenient operation, or uneven locking force, which leads to unstable fiber optic connections, affects communication quality, and the insertion process is complicated, requiring multiple alignments or tool assistance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3In this embodiment of the present invention, a quick-connect fiber optic connector locking mechanism includes an optical fiber 1, a connector 2 installed at one end of the optical fiber 1, a protruding tube 7 fixedly connected to the front end of the optical fiber 1, a connector 6 rotatably connected to the end of the protruding tube 7 away from the optical fiber 1, an inner tube 8 installed in the inner cavity of the end of the connector 6 away from the protruding tube 7, a plug assembly 9 installed in the inner cavity of the inner tube 8, a front tube 4 and a rear tube 5 respectively installed at both ends of the connector 2, the inner tube 8 is provided inside the connector 6, the inner cavity of the inner tube 8 mates with the front tube 4 of the connector, a mounting plate 3 is fixedly connected to the outer wall of the connector 2, the front tube 4 is threadedly connected to the inner cavity of the connector 6, the front end of the front tube 4 is provided with an external thread, which mates with the internal thread of the inner wall of the connector 6, and mechanical locking is achieved by rotation. The rotation operation can complete both mechanical and electrical locking without additional tools, improving installation efficiency. When disassembling, the front tube can be rotated in the opposite direction to unlock, which is convenient for maintenance and replacement. It is suitable for optical fibers of different diameters and various types of signal lines, and has high compatibility.

[0021] Please see Figure 1 One end of the optical fiber 1 away from the protruding tube 7 is fixedly connected to a first wire tube 10. One end of the first wire tube 10 away from the optical fiber 1 is fixedly connected to a second wire tube 11. One end of the second wire tube 11 away from the first wire tube 10 is fixedly connected to a second plug assembly 12. The first wire tube 10 and the second wire tube 11 achieve independent transmission of multiple signal lines (such as optical fiber signals, electrical signals, etc.) through the second plug assembly 12, thus avoiding signal crosstalk.

[0022] Please see Figure 1 The end of fiber optic cable 1 is connected to conductor tube 10. Conductor tube 10 and conductor tube 2 11 cooperate to achieve multi-channel signal conduction through plug-in assembly 2 12. Conductor tube 10 and conductor tube 2 11 are equipped with an insulating separation structure to ensure isolation of each signal channel.

[0023] Please see Figures 1-2 An inner block 13 is installed in the inner cavity of the rear tube 5 and the front tube 4. An opening block 15 is fixedly connected to the outer wall of the inner block 13. The opening block 15 is fixedly connected to the guide rod in the inner cavity of the rear tube 5 and the front tube 4. Both ends of the inner block 13 are provided with a groove 14. One end of the groove 14 is provided with a plug assembly 9. During rotation, the front tube 4 pushes the plug assembly 9 into the groove 14 of the inner tube 8 to complete the electrical connection.

[0024] Please see Figures 1-2The plug assembly 9 includes a plug 16 for plugging into the slot 14. A fixing block 17 is fixedly connected to the upper surface of the outer wall of the plug 16. A spring clip 19 is fixedly connected to the rear part of the upper surface of the fixing block 17. The spring clip 19 fixed at the top of the fixing block 17 automatically engages with the slot of the slot 14 during insertion, forming a mechanical self-lock to prevent axial pull-out. There are two sets of plugs 16. The front end of each set of plugs 16 is equipped with an output guide rod 18. When the plug 16 is inserted into the slot 14, the output guide rod 18 is precisely aligned with the conduction slot of the slot 14 to ensure signal channel connectivity. At the same time, the output guide rod 18 and the slot 14 are aligned with high precision to reduce contact resistance. The multi-channel independent signal design has strong anti-interference capability.

[0025] The 19-position snap-lock design prevents the connection from loosening due to vibration, making it suitable for harsh environments.

[0026] The working principle of this utility model is as follows:

[0027] When in use, align connector 2 with connector 6 and insert it, and insert the insertion assembly 9 in the inner cavity of inner tube 8 into the groove 14 in the inner cavity of front tube 4.

[0028] Specifically: The plug assembly 9 includes a plug 16 that is plugged into a slot 14. During the insertion process of the plug 16 into the slot 14, the fixing block 17 fixed at the top of the plug 16 cooperates with the spring buckle 19. The spring buckle 19 connected to the fixing block 17 will also enter the slot 14 and be locked into the slot of the slot 14. At the same time, the output guide rod 18 at the front end of the plug 16 will also be inserted into the slot of the slot 14 for conduction.

[0029] The rear tube 5 at the front end of the protruding tube 7 is threadedly connected to the front tube 4 connected to the connector 2. The front tube 4 is aligned between the connector 6 and the inner tube 8 and rotated. The rotated front tube 4 and the inner wall of the connector 6 are threaded and fixed, thereby fixing the connector 2 and the connector 6 together.

[0030] The first conduit 10 installed at the end of the optical fiber 1, together with the second conduit 11, is used to connect and conduct with the second plug assembly 12, so that multiple signal lines are transmitted into the first conduit 10.
