[0002] Fiber optic connectors are key components in fiber optic communication systems, used to enable pluggable optical signal connections between fibers and between fibers and devices. Their performance directly affects the insertion loss, return loss, and signal stability of the entire optical communication system, and they are widely used in communication base stations, data centers, transmission networks, industrial control, and other scenarios.

[0003] Currently, common fiber optic connector structures mainly include ferrules, connecting sleeves, housings, and pigtail fixing components. Based on connection type, they can be divided into various standard interfaces such as SC, LC, and FC. With the increasing complexity of network system structures and the continuous improvement of communication capacity, higher demands are being placed on the connection flexibility, density configuration, and ease of use of fiber optic connectors.

[0004] However, existing fiber optic connectors generally have the following problems: one type is a row structure, which usually integrates multiple connectors into a single module. Although it is suitable for large-scale cabling scenarios, the number of connections is fixed, the module is large, and it is not convenient to adjust flexibly according to actual connection needs; the other type is a single independent connector. Although it has a certain degree of flexibility, it is prone to causing cabling chaos in dense connection scenarios, making management inconvenient and installation efficiency low.

[0005] Therefore, existing connector structures have significant limitations in terms of the adjustability of the number of connections, failing to meet the diverse fiber optic connection requirements in practical applications. To achieve flexible configuration and efficient management of the number of fiber optic connections, there is an urgent need to design a fiber optic connector solution that is simple in structure, allows for on-demand combination of connections, and is easy to install and maintain.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example:

[0025] like Figures 1-4 As shown, this utility model provides a plastic optical fiber connection device, including several connection bodies 1; each connection body 1 has a horizontally arranged limiting outer groove 2 on one side; the bottom of the limiting outer groove 2 has a parallel-arranged limiting inner groove 3; the groove depth of the limiting inner groove 3 is greater than the groove depth of the limiting outer groove 2; the limiting inner groove 3 and the limiting outer groove 2 are connected and form a T-shaped structure; each connection body 1 has a limiting part 4 on the other side; the limiting part 4 slides into the limiting inner groove 3 and the limiting outer groove 2 to realize the parallel splicing of adjacent connection bodies 1; the limiting part 4 is a T-shaped limiting block; the connection body 1 has a connection groove 5 that passes through both ends; the connection groove 5 is provided with a fixing component for connecting optical fibers; two optical fibers that need to be connected are inserted from both ends of the connection groove 5 and then connected by the fixing component.

[0026] The principles and beneficial effects of the above technical solution:

[0027] Through the cooperation of the limiting part 4, the inner limiting groove 3, and the outer limiting groove 2, the parallel connection of two adjacent connecting bodies 1 can be realized. Users can quickly combine multiple parallel connection units of connecting bodies 1 by splicing or splitting the connecting bodies 1 according to actual needs, breaking the limitations of the fixed number of connections and non-scalability of traditional row connectors. The connecting bodies 1 are arranged in a modular manner, which can realize high-density splicing, reduce wiring clutter, improve system integration, and facilitate fiber optic connection management and maintenance.

[0028] In this embodiment, a connecting protrusion 6 is provided at one end of the connecting groove 5; a connecting hole 7 is opened on the connecting protrusion 6; a fixing plate 8 is provided inside the connecting groove 5; a fixing hole 9 is opened on the fixing plate 8; a fixing tube 10 is provided between the fixing plate 8 and the connecting protrusion 6; the fixing hole 9 is connected to the connecting hole 7 through the fixing tube 10; the connecting protrusion 6 is inserted into the connecting groove 5 from the other end to realize the overlapping splicing between adjacent connecting bodies 1.

[0029] The principles and beneficial effects of the above technical solution:

[0030] The insertion and mating relationship between the connecting protrusion 6 and the connecting groove 5 allows the connecting bodies 1 to not only be spliced ​​side by side, but also to be spliced ​​longitudinally or overlapping, thereby increasing the diversity of connection methods and the flexibility of combination.

[0031] The fixing tube 10 serves as a reinforced conductive structure between the connecting hole 7 and the fixing hole 9. It not only ensures that the optical fiber can be stably inserted and positioned, but also improves the mechanical strength and tensile strength between the connecting protrusion 6 and the connecting body 1, preventing the splicing part from loosening or deforming.

[0032] In this embodiment, both ends of the connecting protrusion 6 are provided with snap-fit ​​strips 11; the opposite sides of the two snap-fit ​​strips 11 are provided with outer abutment grooves; an outer abutment ball block 12 is connected in the outer abutment groove through a first elastic telescopic member (not shown in the figure); the first elastic telescopic member is a spring damper; the end of the connecting body 1 opposite to the connecting protrusion 6 is provided with a snap-fit ​​groove 13; both sides of the connecting body 1 are provided with exposed grooves 14 that penetrate into the snap-fit ​​grooves 13; the snap-fit ​​strips 11 slide into the snap-fit ​​grooves 13 to reinforce the overlapping splicing between adjacent connecting bodies 1, and the outer abutment ball block 12 is snapped into the exposed groove 14 under the action of the first elastic telescopic member.

[0033] The principles and beneficial effects of the above technical solution:

[0034] Both ends of the connecting protrusion 6 are provided with snap-fit ​​strips 11; the opposite sides of the two snap-fit ​​strips 11 are provided with outer abutment grooves; an outer abutment ball block 12 is connected in the outer abutment groove through a first elastic telescopic member; the first elastic telescopic member is a spring damper; the end of the connecting body 1 opposite to the connecting protrusion 6 is provided with a snap-fit ​​groove 13; both sides of the connecting body 1 are provided with exposed grooves 14 that penetrate into the snap-fit ​​grooves 13; the snap-fit ​​strips 11 slide into the snap-fit ​​grooves 13 to reinforce the overlapping splicing between adjacent connecting bodies 1, and the outer abutment ball block 12 is snapped into the exposed groove 14 under the action of the first elastic telescopic member.

[0035] The elastic locking structure of the outer ball block 12 can effectively prevent abnormal displacement due to external tension and improve the stability of the overlapping splicing of the connecting body 1.

[0036] In this embodiment, a fixing cavity 15 is formed between the fixing plate 8 and the connecting protrusion 6; a horizontally arranged inner abutment groove is opened on the periphery of the fixing tube 10; there are four inner abutment grooves; they are located in pairs on one side of the fixing tube 10; fixing components are respectively provided on both sides of the fixing tube 10; the fixing components include a retractable inner abutment 16 and a torsion member 17; the inner abutment 16 is arranged horizontally on the inner wall of the fixing cavity 15; the torsion member 17 is arranged vertically and rotates through the top side of the connecting body 1 to extend into the fixing cavity 15; the inner abutment 16 is used to press against the optical fiber placed in the fixing cavity 15 through the inner abutment groove; the torsion member 17 is used to release the inner abutment 16 from pressing against the optical fiber.

[0037] The principles and beneficial effects of the above technical solution:

[0038] By setting multiple distributed inner abutment parts 16 to cooperate with the inner abutment groove on the fixing tube 10, the optical fiber can be stably clamped by multiple elastic limits after the optical fiber is inserted into the fixing cavity 15, effectively preventing the optical fiber from shifting, loosening or axially rotating during use, and improving connection reliability.

[0039] The operator can rotate the external torsion member 17 to actuate the internal structure, thereby releasing or applying the clamping force of the internal retainer 16 on the optical fiber, achieving tool-free rapid installation and disassembly. This design simplifies the problems of complex clamping mechanisms and inconvenient adjustment in traditional optical fiber connectors, and features easy operation, compact structure, and stable clamping. It is particularly suitable for optical fiber connection scenarios that require frequent disassembly or fine-tuning, significantly improving the practicality and operational efficiency of the device.

[0040] In this embodiment, the inner abutment 16 includes an inner abutment tube 18, an inner abutment strip 19, and an inner abutment block 20; the inner abutment tube 18 is horizontally disposed on the inner wall of the fixed cavity 15; the inner abutment strip 19 is slidably disposed within the inner abutment tube 18 via a second elastic telescopic member 21; the second elastic telescopic member 21 is a spring damper; the inner abutment block 20 is disposed at the free end of the inner abutment strip 19; the inner abutment block 20 is C-shaped; the vertical sidewall of the inner abutment strip 19 is provided with several locking teeth; the torsion member 17 includes a torsion shaft 22 and a gear 23; the gear 23 is coaxially fixed on the torsion shaft 22 and meshes with the locking teeth; the connecting body 1 has a vertically arranged torsion hole; the torsion shaft 22 is rotatably disposed within the torsion hole; the top end of the torsion shaft 22 is exposed above the connecting body 1.

[0041] The principles and beneficial effects of the above technical solution:

[0042] The torsion shaft 22 is vertically arranged in the torsion hole of the connecting body 1, with its top end exposed outside the connecting body 1 for easy manual or tool operation. The gear 23 meshes with the locking teeth on the inner abutment 19. The user can rotate the torsion shaft 22 to drive the gear 23 to rotate, thereby pushing or releasing the inner abutment 19 and controlling the clamping state of the inner abutment block 20 on the optical fiber.

[0043] This structure uses gear 23 and locking teeth for drive transmission, offering advantages such as precise control and compact structure. Combined with the flexible clamping capability of the inner retaining bar 19 under the action of the elastic telescopic component, it can achieve multi-point stable clamping of the optical fiber inserted into the fixing tube 10, ensuring accurate positioning and good contact, and preventing displacement of the optical fiber due to vibration or pulling. Simultaneously, the exposed design of the torsion shaft 22 allows for clamping or releasing adjustments without disassembling the outer casing, improving installation convenience and maintenance efficiency.

[0044] In this embodiment, a torsion ring 24 is provided at the top end of the torsion shaft 22.

[0045] The principles and beneficial effects of the above technical solution:

[0046] The operator can directly rotate the torsion ring 24 to drive the torsion shaft 22 and its gear 23 to rotate, thereby achieving precise drive control of the inner abutment bar 19, so that the inner abutment block 20 set at the front end of the inner abutment bar 19 can complete the clamping or releasing operation of the optical fiber.

[0047] In this embodiment, the connecting protrusion 6 is provided with a guide groove 25; the connecting groove 5 is provided with a guide strip 26 that cooperates with the guide groove 25.

[0048] The principles and beneficial effects of the above technical solution:

[0049] By setting the guide groove 25 and guide strip 26, an insertion guidance mechanism is established between the connecting bodies 1. This effectively guides the connecting protrusion 6 to slide into the connecting groove 5 along the correct path during the splicing process, preventing jamming, scratching, or damage caused by offset, tilting, or angular errors, thus improving the accuracy and smoothness of assembly. The guide groove 25 and guide strip 26 also provide additional support and limiting functions, enhancing the anti-shaking and structural stability after the connection and splicing, and preventing loosening or misalignment due to vibration or external forces.
