Description

Technical Field

[0001] This application relates to the field of communication device technology, specifically a multi-interface rotating optical fiber communication device. Background Technology

[0002] With the continuous development of information and communication technologies, fiber optic communication systems have been widely used in high-speed data transmission. In fiber optic communication systems, the design of fiber optic connectors and interfaces plays a crucial role, especially in scenarios requiring high bandwidth and low latency transmission. The stability and compatibility of the fiber optic communication equipment's interfaces directly affect the system's performance.

[0003] The installation of FC fiber optic ports typically requires rotating the fiber optic plug to achieve precise alignment with the fiber optic socket. However, this rotation operation has a certain design flaw: during installation, the entire fiber optic port rotates synchronously with the plug. This requires installers to continuously adjust the position of the fiber optic cable during rotation to prevent excessive stretching or bending of the cable, which could affect the fiber's transmission performance or cause physical damage.

[0004] Therefore, this application provides a multi-interface rotating optical fiber communication device to solve the above problems. Utility Model Content

[0005] This application provides a multi-interface rotating optical fiber communication device, which aims to solve the problem mentioned in the background art that optical fiber cables are excessively stretched or bent during installation due to rotation, thereby affecting the transmission performance of the optical fiber or causing physical damage.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-interface rotating optical fiber communication device, comprising an optical fiber communication unit and a plurality of FC-end optical fiber interfaces equidistantly mounted on the optical fiber communication unit, wherein FC optical fiber lines are inserted into the FC-end optical fiber interfaces;

[0007] A fixing mechanism is provided on the FC end fiber optic interface;

[0008] The fixing mechanism includes a fixing base sleeved on the outside of the FC end fiber optic interface and a collar connected to the fixing base. A secondary ring is fixedly connected to the end of the collar away from the fixing base, and a fixing ring is movably connected to the secondary ring. A second threaded surface is opened on the inner side of the fixing ring. A connection port for plugging into the FC end fiber optic interface is provided on the FC fiber optic line. A first threaded surface matching the second threaded surface is provided on the FC fiber optic line, thus constructing a rotating fixing structure with a threaded connection. Through bidirectional threaded engagement, the FC fiber optic line can achieve a tight connection by rotating the fixing ring after being inserted into the interface, avoiding the loosening problem of traditional plug-in interfaces.

[0009] Preferably, the fixed base is symmetrically equipped with guide rail plates that intersect with the outer wall of the FC end fiber optic interface, and the inner side of the collar is equipped with guide blocks that are slidably connected to the guide rail plates, so as to ensure that the collar rotates smoothly along the axis of the FC end fiber optic interface, avoid poor thread engagement caused by eccentricity, and improve connection accuracy.

[0010] Preferably, the mounting base intersects with the optical fiber communication device and is detachably connected via positioning screws.

[0011] Preferably, the inner side of the sub-ring has a groove, and the outer side of the fixed ring is fixedly connected to a movable ring that is rotatably connected to the groove. The separating ring has a guiding function and the fixed ring has a threaded locking function. During operation, only the fixed ring needs to be rotated to drive the optical fiber into the interface, reducing the operating torque.

[0012] Preferably, the outer wall of the fixing ring is provided with a plurality of protrusions arranged in a ring shape, and the protrusions are provided with chamfers to optimize human-computer interaction, prevent fingers from slipping, and are especially suitable for operation while wearing gloves.

[0013] Preferably, a guide scale is installed on the fixing ring.

[0014] This grounding wire take-up and drop device connects the fiber optic communication device to the FC fiber optic cable via the FC end fiber optic interface. In the fixing mechanism, the fixing seat is sleeved outside the interface, and the collar is connected to the fixing seat and drives the secondary ring to rotate. The fixing ring engages with the first threaded surface of the FC fiber optic cable through the second threaded surface to achieve helical locking of the fiber optic cable. When the FC end fiber optic interface is connected to the FC fiber optic cable, locking can be completed simply by rotating the fixing ring. Compared with the traditional rotating FC fiber optic cable fixing method, this solves the problem of fiber optic cable tangling in multi-interface layouts and improves cabling flexibility.

Detailed Implementation

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides a multi-interface rotating optical fiber communication device, such as... Figure 1-5 As shown, the ground wire take-up and release device includes an optical fiber communication unit 1 and several FC end optical fiber interfaces 2 equidistantly installed on the optical fiber communication unit 1, and FC optical fiber cables 3 are inserted into the FC end optical fiber interfaces 2.

[0024] A fixing mechanism 4 is provided on the FC end fiber optic interface 2;

[0025] The fixing mechanism 4 includes a fixing base 41 sleeved on the outside of the FC end fiber optic interface 2 and a collar 43 connected to the fixing base 41. A secondary ring 431 is fixedly connected to the end of the collar 43 away from the fixing base 41. A fixing ring 44 is movably connected to the secondary ring 431. A second threaded surface 441 is opened on the inner side of the fixing ring 44. A connection port 32 for plugging into the FC end fiber optic interface 2 is provided on the FC fiber optic line 3. A first threaded surface 31 that matches the second threaded surface 441 is provided on the FC fiber optic line 3.

[0026] Specifically, the fiber optic communication unit 1 connects to the FC fiber optic cable 3 via the FC end fiber optic interface 2. In the fixing mechanism 4, the fixing seat 41 is fitted outside the interface, and the collar 43 is connected to the fixing seat 41 and drives the secondary ring 431 to rotate. The fixing ring 44 engages with the first threaded surface 31 of the FC fiber optic cable 3 through the second threaded surface 441 to achieve helical locking of the fiber optic cable. The bidirectional thread design provides a locking torque with appropriate strength and can withstand the corresponding axial tensile force, meeting the connection stability requirements under industrial vibration environments. The movable connection between the secondary ring 431 and the fixing ring 44 allows for 360° rotation. When the FC end fiber optic interface 2 is connected to the FC fiber optic cable 3, locking can be completed simply by rotating the fixing ring 44. Compared with the traditional method of fixing the FC fiber optic cable 3 by rotation, this solves the problem of fiber optic cable entanglement in multi-interface layouts and improves cabling flexibility.

[0027] A guide rail plate 42 intersects with the outer wall of the FC end fiber optic interface 2 and is symmetrically installed on the fixed base 41. A guide block 432 that is slidably connected to the guide rail plate 42 is installed on the inner side of the collar 43.

[0028] More specifically, the guide rail plate 42 of the fixed seat 41 slides with the guide block 432 inside the collar 43, which restricts the radial displacement of the collar 43 and only allows axial sliding and circumferential rotation. The guide rail plate 42 and the guide block 432 are precisely matched, with a low coefficient of sliding friction, which is suitable for high-frequency rotation operation. The rail plate is made of alumina ceramic, which improves its wear resistance and life.

[0029] The mounting base 41 intersects with the fiber optic communication unit 1 and is detachably connected via positioning screws 411.

[0030] Furthermore, the mounting base 41 is detachably connected to the fiber optic communication unit 1 via positioning screws 411, allowing for quick disassembly and maintenance. The positioning screws 411 are stainless steel countersunk screws, which can be used with anti-loosening washers to ensure the long-term stability of the mounting base 41.

[0031] The inner side of the secondary ring 431 is provided with a groove, and the outer side of the fixed ring 44 is fixedly connected with a movable ring 443 that is rotatably connected to the groove.

[0032] Furthermore, the groove of the secondary ring 431 is rotatably connected to the movable ring 443 of the fixed ring 44, allowing the fixed ring 44 to rotate independently of the collar 43, thus achieving effortless operation when tightening the thread, allowing for quick tightening with one hand, and making it suitable for high-altitude operations and other operating scenarios.

[0033] The outer wall of the fixing ring 44 is provided with a number of protrusions 45 arranged in a ring shape, and the protrusions 45 are chamfered.

[0034] It should be noted that the protrusions 45 on the outer wall of the retaining ring 44 provide a gripping fulcrum, and the chamfered design improves the comfort of operation and facilitates the rotation of the retaining ring 44. The four protrusions 45 are evenly distributed at 90°, so the force is balanced during rotation, preventing the thread from being worn due to the misalignment of the retaining ring 44. The surface of the protrusions 45 is knurled.

[0035] A guide scale 442 is installed on the fixed ring 44.

[0036] It is worth mentioning that the guide scale 442 marks the position of the second threaded surface 441 for insertion, which helps to determine the insertion depth of the FC optical fiber 3 and the insertion angle of the first threaded surface 31 on the FC optical fiber 3.

[0037] In use, the fiber optic communication unit 1 connects to the FC fiber optic cable 3 through the FC end fiber optic interface 2. In the fixing mechanism 4, the fixing seat 41 is sleeved outside the interface, and the collar 43 is connected to the fixing seat 41 and drives the secondary ring 431 to rotate. The fixing ring 44 cooperates with the first threaded surface 31 of the FC fiber optic cable 3 through the second threaded surface 441 to realize the spiral locking of the fiber optic cable. When the FC end fiber optic interface 2 is connected to the FC fiber optic cable 3, locking can be completed by simply rotating the fixing ring 44. Compared with the traditional method of fixing the FC fiber optic cable 3 by rotating it, the problem of fiber optic cable entanglement in multi-interface layout is solved, and the wiring flexibility is improved.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
