Abstract
Description
Technical Field
[0001] This utility model belongs to the field of patch cord connector technology, specifically a patch cord connector for a detachable optical cable junction box. Background Technology
[0002] Optical cable junction boxes are switching devices for backbone optical cable nodes in optical fiber access networks. They are mainly used to provide optical cable termination and patching for backbone and distribution optical cables. They have functions such as direct connection, patching, coiling, storage, and adjustment for optical fibers. They are widely used in optical fiber networks in telecommunications, broadcasting, and China Unicom, including optical fiber access networks, optical fiber backbone networks, optical fiber data transmission, cable television networks, and digital television networks. They are also key equipment for realizing broadband access networks such as Fiber to the Home (FTTH), Fiber to the Building (FTTB), and Fiber to the Curbside (FTTC).
[0003] Patch cords in fiber optic junction boxes are crucial components for fiber optic connections and optical path configuration. Within these boxes, patch cords connect different fiber optic lines, accurately linking the fiber cores in the trunk cable with those in the distribution cable, thus enabling signal transmission and distribution. Patch cords also facilitate easy adjustment and allocation of optical paths, allowing for the connection of fibers of different directions and purposes according to actual needs, meeting the requirements of network topology changes and business development. They are typically composed of ferrules, sleeves, and outer shells.
[0004] In the existing technology, the outer shell of the jumper connector is generally fixed. As a protective structure, the outer shell is easily damaged by external forces. Once it is damaged, the entire connector must be replaced, resulting in waste.
[0005] Therefore, a patch cord connector for a detachable optical cable junction box is proposed to address the above issues. Utility Model Content

[0027] 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.
[0028] like Figures 1 to 5 As shown, this utility model provides a patch cord connector for a detachable optical cable junction box, including a fixing block 1, a ferrule 2 fixedly connected to the fixing block 1, an optical fiber 3 fixedly connected to the ferrule 2, the optical fiber 3 passing through the fixing block 1, a sleeve 4 provided on the outside of the ferrule 2, the sleeve 4 fixedly connected to the fixing block 1, a housing 5 provided on the outside of the sleeve 4, the housing 5 threadedly connected to the fixing block 1, and a positioning component 6 connected between the fixing block 1 and the housing 5. By providing a detachable housing 5, it can be replaced in time after being broken by external pressure, avoiding the need to replace the whole unit, and the positioning component 6 ensures the stability of the position of the housing 5.
[0029] The positioning component 6 includes a mounting groove 601 formed on the fixed block 1. A movable plate 602 is provided in the mounting groove 601. A spring 603 is connected to the side of the movable plate 602 away from the center of the fixed block 1. An L-shaped connecting rod 604 is provided inside the spring 603. One end of the L-shaped connecting rod 604 is fixedly connected to the movable plate 602, and the other end is fixedly connected to a connecting block 605. A serrated groove plate 606 is fixedly connected to the connecting block 605. A serrated ring 607 corresponding to the serrated groove plate 606 is fixedly connected to the outside of the outer shell 5.
[0030] Specifically, the lengths of the insert 2, sleeve 4, and outer shell 5 gradually increase.
[0031] Furthermore, a protective sleeve 7 is provided on the outside of the optical fiber 3, and the protective sleeve 7 is fixedly connected to the fixing block 1.
[0032] Furthermore, the sleeve 4 is provided with a tensile component 8, which includes a groove 801 formed on the sleeve 4. A rotating rod 802 that rotatably connects to the sleeve 4 is provided in the groove 801. A push plate 803 and a convex rubber block 804 are respectively provided on the rotating rod 802. The push plate 803 and the convex rubber block 804 are set at a 90-degree angle. When the jumper connector is inserted into the socket, the convex rubber block 804 can abut against the inner wall of the corresponding position of the socket to increase the friction between them, improve the tensile strength, and prevent the jumper connector from accidentally coming off the socket.
[0033] It is worth noting that the size of the groove 801 matches that of the push plate 803 and the convex rubber block 804, and both the push plate 803 and the convex rubber block 804 can be inserted into the groove 801.
[0034] It is worth noting that a threaded protrusion 9 is fixed on the fixing block 1 at the position corresponding to the outer shell 5, and a threaded groove 10 is provided on the inner wall of the outer shell 5 at the position corresponding to the threaded protrusion 9.
[0035] Working principle and process: When the outer casing 5 needs to be removed, pull the L-shaped connecting rod 604 of the positioning component 6, thereby disengaging the serrated groove plate 606 from the serrated ring 607. Then rotate the outer casing 5 to disengage the threaded protrusion ring 9 from the threaded groove 10, allowing the outer casing 5 to be removed. Thread the new outer casing 5 onto the fixing block 1, loosen the serrated groove plate 606, and under the action of the spring 603, the serrated groove plate 606 adheres to the serrated ring 607 to prevent the outer casing 5 from rotating, ensuring the connection strength between the outer casing 5 and the fixing block 1. (The last sentence appears to be incomplete and possibly refers to a jumper wire connection.) When the connector is inserted into the socket, the socket component enters the position between the sleeve 4 and the housing 5. As the jumper connector is inserted, it pushes the push plate 803 to rotate around the rotating rod 802. As the push plate 803 and the rotating rod 802 rotate, the convex rubber block 804 also rotates. After the push plate 803 is pushed into the groove 801, the convex rubber block 804 will abut against the inner wall of the corresponding position of the socket to increase the friction between the jumper connector and the socket, enhance the stability of the jumper connector, and facilitate the use of the jumper connector.
