Description

Technical Field

[0001] This utility model relates to the field of fiber optic patch cord installation technology, and in particular to an MPO fiber optic patch cord that is easy to install. Background Technology

[0002] MPO fiber optic patch cords are multi-core fiber optic patch cords that use MPO / MTP connectors and are widely used in data centers, communication networks, and other fields. During installation, MPO fiber optic patch cords require simple installation to reduce installation time and improve construction efficiency, while ensuring connection stability and performance, and avoiding the risk of failure caused by complex operations. Existing technology requires tightening the end cap to the connector after plugging the fiber optic patch cord into the connector; this repeated tightening of the end cap increases the complexity and time of installation.

[0003] As shown in the reference case "A Single-Mode Fiber Optic Patch Cord" (publication number CN217238452U), when installing the fiber optic cable and the first connector block, the integrally formed cylindrical shell can be directly fitted onto the outer wall of the sheath, so that the rotating part is tightly abutted against the outer wall of the fiber core, thereby pre-fixing the entire cylindrical shell. Then, the outside of the entire cylindrical shell is heated, causing the sheath on the through hole to expand and be squeezed into the through hole. After cooling, it is naturally fixed into the through hole, thus completing the fixation of the cylindrical shell and the sheath, thereby simplifying the installation parts and steps and saving manpower.

[0004] The aforementioned application requires the rotating component to be screwed into the inner wall of the second connector before heating the outside of the cylindrical shell to pre-fix it to the cylindrical shell, and then the outside of the cylindrical shell is heated to complete the fixing. This process is complicated and takes too long, making it inconvenient for the rapid installation of fiber optic patch cords. Utility Model Content

[0005] Therefore, it is necessary to provide an MPO fiber optic patch cord that is easy to install, addressing the problem of overly complex installation processes for fiber optic patch cords.

[0006] An easy-to-install MPO fiber optic patch cord includes: a connector and an open / close adapter at one end of the connector.

[0007] The mounting mechanism includes a first mounting component disposed on the surface of the adapter and a second mounting component for limiting the position of the adapter.

[0008] In one embodiment, the first mounting component includes two positioning rings fitted onto the surface of the adapter, both positioning rings being semi-circular in shape, and the surface of the adapter having two guide grooves in the shape of a "7".

[0009] In one embodiment, the second mounting assembly includes a fixing cylinder sleeved on the surface of the adapter, and two sliders are fixedly connected to the inner wall of the fixing cylinder, the sliders cooperating with the guide groove.

[0010] In one embodiment, a spring plate is slidably connected to the inner wall of the positioning ring, and a plurality of first springs are fixedly connected between the spring plate and the inner wall of the positioning ring. A driving block is slidably connected to the surface of the positioning ring, and the bottom end of the driving block penetrates the positioning ring and is fixedly connected to the spring plate.

[0011] In one embodiment, the inner wall of the positioning ring is provided with a slot, which is located on the side of the spring plate away from the first spring.

[0012] In one embodiment, a locking block is provided at one end of the fixing cylinder, and the locking block is shaped to match the locking groove.

[0013] In one embodiment, the inner wall of the fixed cylinder is provided with a reset groove, and one end of the locking block extends into the reset groove and is slidably connected to the reset groove.

[0014] Beneficial effects

[0015] 1. By using a slider inside the fixed cylinder to engage with a groove at the adapter, after the fiber optic patch cord is installed, the fixed cylinder can be directly slid onto the adapter surface, and then a slight rotation is sufficient to secure the adapter. This design greatly simplifies the traditional tightening process, eliminates the need for repeatedly tightening the end cap, and reduces the time and labor required for installation. Compared to traditional methods, this improvement enhances the installation efficiency of fiber optic patch cords.

[0016] 2. By using a positioning ring in conjunction with a locking block on the fixing cylinder, the fixing cylinder can be quickly disassembled, facilitating the maintenance of the adapter interface and fiber optic patch cords. This not only improves the ease of disassembly and reduces maintenance time but also ensures convenient inspection and replacement of fiber optic patch cord components during daily use. Maintenance personnel can quickly troubleshoot or replace parts without complex tools, further improving the overall maintenance efficiency and reliability of the system and reducing maintenance costs.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figures 1-5 This invention describes an MPO fiber optic patch cord that is easy to install.

[0027] In one embodiment, an easy-to-install MPO fiber optic patch cord includes: a connector 100 and an openable adapter 200 disposed at one end of the connector 100.

[0028] The mounting mechanism 300 includes a first mounting component 310 disposed on the surface of the adapter 200 and a second mounting component 320 for limiting the adapter 200.

[0029] The connector 100 in this device mainly consists of a ferrule, a guide pin, and a spring pressure mechanism. The ferrule ensures precise alignment of the optical fiber, the guide pin corrects the mating angle, and the spring mechanism provides axial pressure to ensure tight contact between the end faces. When the optical fiber is inserted into the connector 100, its end face makes physical contact with the corresponding ferrule inside the adapter, and optical signal transmission is achieved through the Fresnel reflection principle.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the first mounting component 310 includes two positioning rings 312 sleeved on the surface of the adapter 200. Both positioning rings 312 are semi-circular. Two guide grooves 311 are formed on the surface of the adapter 200, and these guide grooves 311 are in the shape of a "7". The second mounting component 320 includes a fixing cylinder 322 sleeved on the surface of the adapter 200. Two sliders 321 are fixedly connected to the inner wall of the fixing cylinder 322, and the sliders 321 cooperate with the guide grooves 311. A spring plate 3121 is slidably connected to the inner wall of the positioning ring 312. Multiple first springs 3122 are fixedly connected between the spring plate 3121 and the inner wall of the positioning ring 312. A driving block 3123 is slidably connected to the surface of the positioning ring 312, and the bottom end of the driving block 3123 penetrates the positioning ring 312 and is fixedly connected to the spring plate 3121. The inner wall of the positioning ring 312 is provided with a slot 3124, which is located on the side of the spring plate 3121 away from the first spring 3122.

[0031] In this embodiment, the adapter 200 consists of two parts. One part is directly fixedly connected to the outer shell of the interface, while the other part is hinged to the side of the first part. When installing a fiber optic patch cord, the upper part of the adapter 200 needs to be unfolded first to expose the internal storage groove of the adapter 200. Then, the fiber optic cable is inserted into the connector 100 through this part and connected to the adapter inside the connector 100. The outer shell of the fiber optic cable is located in the storage groove inside the adapter 200. Two positioning rings 312 are fixedly connected to the two parts of the adapter 200 respectively. At the same time, two rectangular openings are opened on the side of the positioning rings 312 away from the connector 100. When the fixing cylinder 322 slides along the slide... When the slot slides to the end, the locking block 3221 is inserted into the interior of the positioning ring 312 through the rectangular opening. Before the locking block 3221 is inserted into the positioning ring 312, the driving block 3123 needs to be manually slid. The lower surface of the driving block 3123 is inserted into the positioning ring 312 through the connecting rod and is fixedly connected to the spring plate 3121. At the same time, the surface of the spring plate 3121 is provided with a through groove for the positioning ring 312 to move, and the surface of the positioning ring 312 is provided with a limiting groove for positioning the driving block 3123. The area of ​​the driving block 3123 covers the through groove. Therefore, when the driving block 3123 is not subjected to external force, it covers the through groove to protect the interior of the positioning ring 312 from external impurities.

[0032] It should be noted that the installation mechanism 300 in this device optimizes the traditional connector 100 by screwing the end cap and connecting block at the end of the connector 100 together with threads. Instead, it allows the fixing cylinder 322 to be slidably inserted and then rotated slightly to complete the fixing. Therefore, the installation mechanism 300 only improves the connecting block at the adapter 200 and will not affect the internal structure of the connector 100 or the connection between the optical fiber and the adapter inside the connector 100. At the same time, the installation mechanism 300 of this device only serves to fix the connector 200 and will not affect the structure or installation of the optical fiber. Therefore, the installation mechanism 300 of this device will not affect the normal connection between the connector 100 and the optical fiber or the normal function of the optical fiber.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, a locking block 3221 is provided at one end of the fixed cylinder 322, and the shape of the locking block 3221 matches that of the locking groove 3124. A reset groove 3222 is provided on the inner wall of the fixed cylinder 322, and one end of the locking block 3221 extends into the reset groove 3222 and is slidably connected to the reset groove 3222.

[0034] In this embodiment, when maintenance of the optical fiber is required, the drive block 3123 is manually pushed. The drive block 3123 moves the spring plate 3121 away from the locking block 3221. At this time, the locking block 3221 loses the pressure from the spring plate 3121. Previously, the locking block 3221 was under the pressure of the spring plate 3121, and it moved along the reset groove 3222, compressing the second spring 3223, thus locking the locking block 3221 into the slot 3124. Now, due to the loss of spring pressure... The release of the second spring 3223 generates elastic force, which drives the locking block 3221 to reset. At this time, the locking block 3221 disengages from the locking groove 3124. Then, by rotating the fixing cylinder 322 in the opposite direction, the fixing cylinder 322 can be removed from the adapter 200, thereby loosening the adapter 200 for maintenance. The locking block 3221 is also slidably connected to the reset groove 3222 by a connecting rod. One end of the connecting rod located in the reset groove 3222 is disc-shaped, and the disc-shaped part is fixedly connected to the second spring 3223.

[0035] Working principle: After stripping, cleaning and cutting the fiber optic patch cord, the fixing sleeve 322 is first inserted into the surface of the fiber optic cable. Then, the fiber optic cable is inserted into the connector 100 through the adapter 200. After feeling a slight vibration, the insertion of the fiber optic patch cord can be stopped. At this time, the fiber optic cable is connected to the terminal in the interface. Then, the adapter 200 is partially merged and the fixing sleeve 322 is placed on the outside of the adapter 200 to complete the fixation.

[0036] When fitting the fixed cylinder 322 into the adapter 200, the slider 321 inside the fixed cylinder 322 needs to be aligned with the slide groove, allowing the slider 321 to slide along the slide groove to its end. At this point, the two locking blocks 3221 will be inserted into their respective positioning rings 312. The drive block 3123 needs to be manually moved, causing the spring plate 3121 to compress the first spring 3122 and slide, providing space for the locking blocks 3221 to move. Then, the fixed cylinder 322 is rotated, causing the locking blocks 3221 to move within the positioning rings 312. The internal rotation of 2 is accompanied by the sliding block 321 sliding along the corner of the slide groove. When the sliding block 321 slides to the end of the corner of the slide groove, the locking block 3221 is aligned with the locking groove 3124. At this time, the locking block 3221 is aligned with the locking groove 3124. Then the drive block 3123 is released. At this time, multiple first springs 3122 push the spring plate 3121 at the same time. The spring plate 3121 squeezes the locking block 3221 and squeezes the locking block 3221 into the locking groove 3124, thus completing the limiting of the fixed block. This completes the fixing of the adapter 200.

[0037] It should be noted that the connector 100, the first spring 3122, the second spring 3223 and the adapter 200 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
