Description

Technical Field

[0001] This utility model relates to the field of optical communication equipment technology, specifically to an optical fiber positioning sleeve for optical modules. Background Technology

[0002] As a core component of optical communication systems, the connection accuracy of optical fiber interfaces and fiber optic patch cords directly determines the efficiency and stability of optical signal transmission. In application scenarios such as data centers and enterprise networks, optical modules are often installed inside equipment such as servers. The insertion and removal of fiber optic patch cords are frequent and easily affected by equipment vibration, cable pulling, etc.

[0003] The fiber optic connections of existing optical modules mostly rely on the interface's own snap-fit ​​structure. When the fiber optic patch cord is inserted, there is no precise guiding constraint, which can easily lead to radial offset. This causes the coaxiality of the fiber optic ferrule and the optical module interface to deviate, resulting in problems such as decreased optical coupling efficiency and signal attenuation. In addition, the traditional snap-fit ​​structure has insufficient locking reliability and is prone to loosening after long-term use.

[0004] Therefore, it is necessary to invent an optical module fiber positioning sleeve to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an optical fiber positioning sleeve for optical modules. Through the coordinated design of the guide component and the positioning component, it can achieve precise guidance when inserting optical fiber patch cords, elastic self-locking after connection, and convenient disassembly and assembly during maintenance, so as to solve the problems of low positioning accuracy and unreliable locking of optical fiber connections in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical module fiber positioning sleeve, comprising; An external mounting base is installed on the optical fiber interface of the optical module. A jumper is inserted inside the optical fiber interface of the optical module. The mounting base is U-shaped. A guide assembly is fixedly connected to the front side of the mounting base. The guide assembly includes a barrier. The barrier is fixedly connected to the front side of the mounting base. A guide groove is provided on the front side of the barrier near the jumper. A positioning component is fixedly installed on the front side of the mounting base. The positioning component includes a connector, which is fixedly connected to the front side of the mounting base and the lower part of the enclosure. A through groove is opened on the upper part of the connector near the middle of the enclosure. A support shaft is fixedly connected to the front part of the connector. A limiting part is inclinedly provided on the outer side of the support shaft. The limiting part slides on the inner wall of the through groove. An operating part is fixedly connected to the lower part of the limiting part. The support shaft and the connector are elastically connected by an elastic element. A limiting groove is opened on the lower part of the jumper wire, and the limiting part is engaged with the inner wall of the limiting groove.

[0007] Preferably, the enclosure is configured in an E-shape.

[0008] Preferably, the interior of the connector is hollow, and the rear side of the operating part abuts against the outer side of the connector.

[0009] Preferably, the upper part of the limiting part is horizontally positioned, and the upper horizontal area of ​​the limiting part is engaged inside the limiting groove.

[0010] Preferably, the elastic element is a torsion spring, one end of which is inserted into the inner wall of the connector, and the other end of which abuts against the rear side of the limiting part.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model features an E-shaped guide groove that precisely matches the fiber optic patch cord, creating axial and radial dual constraints during insertion to prevent patch cord misalignment and ensure that the coaxiality deviation between the fiber optic ferrule and the optical module interface is controlled within the micrometer level.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3 The optical module fiber positioning sleeve shown includes a mounting base 1 and a positioning component 3 installed on the outside of the optical fiber interface of the optical module. The mounting base 1 is used to fit and fix to the outside of the optical fiber interface of the optical module, and provides a stable installation reference for the guide component 2 and the positioning component 3. The optical fiber interface of the optical module has an internal optical fiber patch cord 4, which serves as the carrier for optical signal transmission. It needs to be precisely connected to the optical module interface to ensure signal transmission. The mounting base 1 is U-shaped and can be adapted to the outer contour of the optical fiber interface of the optical module. It can be installed with screws without modifying the original structure of the module. The front side of the mounting base 1 is fixedly connected to the guide component 2, which provides guidance and constraint for the insertion of the optical fiber patch cord 4 and avoids deviation during the insertion process. The guide component 2 includes a barrier 21, which is used to limit the installation area of ​​the optical fiber patch cord 4 and at the same time protect the connection between the patch cord 4 and the interface. The barrier 21 is fixedly connected to the front side of the mounting base 1 and forms an integrated structure with the mounting base 1 to ensure guidance stability. The front side of the barrier 21 near the optical fiber patch cord 4 has a guide groove 22, which is precisely adapted to the shape of the optical fiber patch cord 4 to achieve axial and radial dual guidance during the insertion process and ensure docking accuracy. The positioning component 3 is used to lock the fiber optic patch cord 4 in a precise docking position to prevent loosening or displacement. The positioning component 3 is fixedly installed on the front side of the mounting base 1, forming a cooperative positioning structure with the mounting base 1 and the guide component 2. The positioning component 3 includes a connector 31, which serves as the mounting carrier for the positioning component 3 and connects the mounting base 1, the enclosure 21, and the support shaft 33. The connector 31 is fixedly connected to the front side of the mounting base 1 and the lower part of the enclosure 21, achieving a stable connection between the positioning component 3, the guide component 2, and the mounting base 1. A through groove 32 is provided on the upper part of the connector 31 near the middle of the enclosure 21 to provide room for the sliding of the limiting part 34 and avoid motion interference. The front part of the connector 31 is fixedly connected to the support shaft 33, which serves as the rotation support point for the limiting part 34, ensuring that the limiting part 34 can rotate flexibly. A limiting part 34 is inclinedly provided on the outer side of the support shaft 33. Through the snap-fit ​​with the limiting groove 37, the axial limiting of the fiber optic patch cord 4 is realized. The limiting part 34 slides on the inner wall of the through groove 32 and can slide flexibly along the through groove 32 to realize the switching between locking and unlocking. The lower part of the limiting part 34 is fixedly connected to the operating part 35, which is convenient for manual pressing operation to quickly release the limiting lock. The support shaft 33 and the connector 31 are elastically connected through the elastic element 36 to provide continuous pre-tightening force for the limiting part 34, ensuring that it automatically snaps into the limiting groove 37 and remains locked. The lower part of the fiber optic patch cord 4 has a limiting groove 37, which is adapted to the horizontal area of ​​the limiting part 34 to form a reliable snap-fit ​​structure. The limiting part 34 snaps into the inner wall of the limiting groove 37 to realize the precise positioning and stable fixation of the fiber optic patch cord 4.

[0017] like Figure 3 - Figure 5 As shown, the enclosure 21 is E-shaped, which can simultaneously form a wrap-around guide for both sides and the middle of the fiber optic patch cord 4, improving guidance stability and protection effect; the connector 31 is hollow inside, providing installation space for the elastic element 36, while reducing structural weight; the rear side of the operating part 35 abuts against the outside of the connector 31, limiting the stroke of the operating part 35; the upper part of the limiting part 34 is horizontally set, fully fitting against the inner wall of the limiting groove 37, improving the snap-fit ​​stability and preventing it from falling off under force; the upper horizontal area of ​​the limiting part 34 snaps into... The interior of the limiting groove 37 forms a surface contact locking mechanism, enhancing the reliability of the limiting mechanism. The elastic element 36 is set as a torsion spring, which has good elastic recovery performance and can provide a stable preload for a long time. One end of the elastic element 36 is inserted into the inner wall of the connector 31 to achieve fixed installation of the elastic element 36, and the other end of the elastic element 36 abuts against the rear side of the limiting part 34 to provide a continuous rotational preload for the limiting part 34, ensuring a stable locking state. The elastic element 36 can resist the vibration of the equipment, so there is no need to consider the problem of the elastic element 36 being affected by vibration.

[0018] The working principle of this utility model is as follows: First, the U-shaped mounting base 1 is attached to the outside of the optical fiber interface of the optical module. The mounting base 1 is fixed by screws, so that the guide component 2 and the positioning component 3 form a positioning reference coaxial with the optical module interface. At this time, the E-shaped enclosure 21 encloses the installation area of ​​the jumper 4, providing protection and limiting for subsequent insertion.

[0019] Align the fiber optic patch cord 4 with the guide groove 22 of the E-shaped enclosure 21, and slowly insert it into the optical module interface along the axial and radial constraint directions of the guide groove 22. The guide groove 22 and the shape of the fiber optic patch cord 4 are precisely matched, which can avoid misalignment during the insertion process and ensure the initial alignment of the fiber optic ferrule and the optical module interface.

[0020] During the insertion of the fiber optic patch cord 4, the lower limiting groove 37 moves synchronously with the patch cord 4. When the limiting groove 37 moves to the position corresponding to the limiting part 34 of the positioning component 3, the pre-tightening force of the elastic element 36 pushes the limiting part 34 to rotate along the support shaft 33, so that its upper horizontal area automatically locks into the inner wall of the limiting groove 37. At this time, the limiting part 34 and the limiting groove 37 form a surface contact lock, and the elastic element 36 continuously provides elastic pre-tightening force.

[0021] When it is necessary to replace or maintain the fiber optic patch cord 4, manually press the operating part 35 forward. The rear side of the operating part 35 abuts against the outer side of the connector 31 to form a limit, preventing excessive pressure from damaging the components. The pressing force is transmitted to the limiting part 34 through the support shaft 33, causing it to overcome the preload of the elastic member 36 and slide along the through groove 32. The upper horizontal area disengages from the limiting groove 37, releasing the locking constraint on the fiber optic patch cord 4. At this time, the patch cord 4 can be directly pulled out along the guide groove 22 to complete the disassembly.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
