Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to a fusion-type optical fiber connector with self-locking function. Background Technology

[0002] Fusion-terminated fiber optic connectors are a common type of fiber optic connection and are widely used in optical communication systems. While traditional fusion-terminated connectors can provide good fiber optic connection performance, they are prone to loosening or detachment during installation and maintenance. Fusion-terminated fiber optic connectors with self-locking function can ensure that the connector is more stable and reliable during use and avoid loosening.

[0003] However, in actual use, the following shortcomings still exist. For example, existing fusion-type fiber optic connectors cannot achieve stable self-locking, convenient unlocking, and dual dustproof effects. Interfaces that are not securely locked may experience slight displacement due to vibration or temperature changes, leading to mode distribution disturbances. Being in a critical state for a long time will accelerate fatigue aging. In dynamic application scenarios such as mobile devices, several impacts per second may cause momentary interruptions, resulting in an increased data packet loss rate. Frequent manual intervention to adjust the position will increase the scratch rate of ceramic ferrules and shorten their service life. After repeated deformation of the metal spring, stress relaxation occurs, resulting in a decrease in locking force. When outdoor base stations encounter strong wind loads, substandard locking mechanisms may completely disengage.

[0004] Therefore, this utility model proposes a fusion-type fiber optic connector with self-locking function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fusion-type fiber optic connector with a self-locking function.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a fusion-type fiber optic connector with self-locking function, comprising an optical fiber, and further comprising:

[0007] The self-locking assembly includes a connecting block connected to an optical fiber, a limiting frame connected to the connecting block, a connector slidably connected to the limiting frame, a snap-fit ​​block connected to the limiting frame, a snap-fit ​​block rotatably connected to the limiting frame, a limiting block connected to the side of the connecting block near the snap-fit ​​block, a second spring piece provided on the snap-fit ​​block, and a telescopic spring provided inside the limiting frame.

[0008] A dustproof assembly, comprising a dust cover disposed on the connecting block near the outer side of the connector, wherein a dust cap is disposed on the connector.

[0009] Furthermore, a first spring tab is connected to the side of the limiting frame near the snap-fit ​​block.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the first spring piece is close to the locking block and is slightly convex in its natural state. When docking, the locking block is inserted into the matching slot. When the first spring piece is pressed to unlock, its elasticity pushes the locking block out of the slot, providing initial power for subsequent unlocking.

[0011] Furthermore, one end of the second spring is connected to the locking block, and the other end of the second spring is connected to the limiting frame.

[0012] The beneficial effects of adopting the above-mentioned further solution are: one end of the second spring is connected to the locking block and the other end is connected to the limiting frame. When the connector is inserted, the limiting block pushes the locking block to rotate, and the second spring is compressed and deformed to store elastic potential energy. When unlocking, the second spring releases elastic potential energy, which drives the locking block to disengage from the slot.

[0013] Furthermore, one end of the telescopic spring is connected to the limiting frame, and the other end of the telescopic spring is connected to the connector.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the telescopic ends are respectively connected to the limiting frame and the connector. When the connector is pushed to mate, the telescopic spring is compressed and stored, so that the connector can be stably locked. After unlocking, the telescopic spring releases elastic potential energy to assist in completing the separation action.

[0015] Furthermore, a limiting plate is connected to the side of the connecting block away from the connecting head.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the limiting plate is located on the side of the connecting block away from the connector, which limits the excessive displacement of the dust cover and prevents the dust cover from falling off the connecting block.

[0017] Furthermore, a sealing ring is connected to the side of the limiting frame near the connector.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the sealing ring is located on the side of the limiting frame near the connector, and fits tightly with the connection between the limiting frame and the connector, preventing dust and moisture from entering the interior and reducing the impact of the external environment on the connection.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when the connector is inserted, the connector head is pushed to slide along the limiting frame, and the connector head compresses the telescopic spring. During the docking process, the locking block on the limiting frame is initially positioned with the adapter slot. During the insertion of the connector head, the limiting block pushes the locking block to rotate and engage with the adapter slot. Due to the rotation of the locking block, the second spring plate deforms and generates elastic potential energy. When unlocking, pressing the first spring plate first disengages the locking block from the slot. Subsequently, the second spring plate releases its elastic potential energy, causing the locking block to disengage from the slot, thus unlocking the connector. In the dustproof assembly, the dust cover on the connector block covers the outside of the connector head, and the dust cap on the connector head seals the port to prevent dust from entering, thereby achieving a stable self-locking, convenient unlocking, and dual dustproof effect.

[0030] 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.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a fusion-type fiber optic connector with self-locking function, including an optical fiber 1, and further including:

[0032] The self-locking component 2 includes a connecting block 21 connected to the optical fiber 1, a limiting frame 22 connected to the connecting block 21, a connector 23 slidably connected inside the limiting frame 22, a snap-fit ​​block 24 connected to the limiting frame 22, a snap-fit ​​block 26 rotatably connected to the limiting frame 22, a limiting block 27 connected to the side of the connecting block 21 near the snap-fit ​​block 26, a second spring 28 provided on the snap-fit ​​block 26, and a telescopic spring 29 provided inside the limiting frame 22.

[0033] Dustproof component 3 includes a dust cover 32 disposed on the connecting block 21 near the outside of the connector 23. The connector 23 is equipped with a dust cap 34. When the connector is inserted, the connector 23 is pushed to slide along the limiting frame 22, compressing the telescopic spring 29. During the docking process, the locking block 24 on the limiting frame 22 is initially positioned with the adapter slot. Furthermore, during the insertion of the connector 23, the limiting block 27 pushes the locking block 26 to rotate and engage with the adapter slot. The rotation of 6 causes the second spring 28 to deform, generating elastic potential energy. When unlocking, pressing the first spring 25 first disengages the locking block 24 from the slot. Then, the second spring 28 releases its elastic potential energy, causing the locking block 26 to disengage from the slot, thus unlocking the connector. In the dustproof assembly 3, the dust cover 32 on the connecting block 21 covers the outside of the connector 23, and the dust cap 34 on the connector 23 seals the port to prevent dust from entering, thereby achieving a stable self-locking, convenient unlocking, and dual dustproof effect.

[0034] The above solutions also have the problem that, when the connector needs to be unlocked, the auxiliary card block 24 and card block 26 cannot be disengaged from their corresponding card slots. Figures 2-4As shown: A first spring piece 25 is connected to the side of the limiting frame 22 near the locking block 24. The first spring piece 25 is slightly convex in its natural state near the locking block 24. When mating, the locking block 24 engages with the matching slot. When unlocking, pressing the first spring piece 25 causes its elasticity to push the locking block 24 out of the slot, providing initial power for subsequent unlocking. One end of the second spring piece 28 is connected to the locking block 26, and the other end of the second spring piece 28 is connected to the limiting frame 22. One end of the second spring piece 28 is connected to the locking block 26, and the other end is connected to the limiting frame 22. When the connector 23 is inserted... When the limiting block 27 pushes the locking block 26 to rotate, the second spring 28 is compressed and deformed to store elastic potential energy. When unlocking, the second spring 28 releases elastic potential energy, causing the locking block 26 to disengage from the slot. One end of the telescopic spring 29 is connected to the limiting frame 22, and the other end of the telescopic spring 29 is connected to the connector 23. The two ends of the telescopic spring are connected to the limiting frame 22 and the connector 23 respectively. When the connector 23 is pushed to engage, the telescopic spring 29 is compressed and stores energy, enabling the connector to lock stably. After unlocking, the telescopic spring 29 releases elastic potential energy to assist in completing the separation action.

[0035] like Figures 1-5 As shown, a limiting plate 31 is connected to the side of the connecting block 21 away from the connector 23. The limiting plate 31 is located on the side of the connecting block 21 away from the connector 23, which limits the excessive displacement of the dust cover 32 and prevents the dust cover 32 from falling off the connecting block 21. A sealing ring 33 is connected to the side of the limiting frame 22 near the connector 23. The sealing ring 33 is located on the side of the limiting frame 22 near the connector 23 and fits tightly with the connection between the limiting frame 22 and the connector 23, blocking dust and moisture from entering the interior and reducing the impact of the external environment on the connection.

[0036] Working principle:

[0037] like Figures 1-5As shown, when the connector is inserted, it pushes the connector head 23 to slide inward along the limiting frame 22. At this time, the connector head 23 compresses the telescopic springs 29 connected to the limiting frame 22 and itself at both ends, storing elastic potential energy. During the docking process, the snap-fit ​​block 24 on the limiting frame 22 first embeds into the adapter slot to complete the initial positioning. As the connector head 23 continues to be inserted, the limiting block 27 on the connector block 21 pushes the snap-fit ​​block 26 to rotate, so that it snaps into the adapter slot to achieve a deep engagement. During this process, the second spring piece 28 connected to the snap-fit ​​block 26 is compressed and deformed, storing elastic potential energy simultaneously. Combined with the elastic force of the telescopic spring 29, a double locking structure is formed to ensure a stable connection. During the unlocking operation, the first spring piece 25 on the limiting frame 22 is pressed, pushing the adjacent snap-fit ​​block 28 to engage. Block 24 disengages from the slot. Subsequently, the second spring 28 releases its stored elastic potential energy, causing the locking block 26 to rotate in the opposite direction and disengage from the slot. At the same time, the telescopic spring 29 returns to its original shape, pushing the connector 23 to reset along the limiting frame 22, thus achieving complete unlocking. In terms of dust protection, the dust cover 32 on the connecting block 21 covers the outside of the connector 23, which, together with the dust cap 34 on the connector 23, seals the port. In addition, the sealing ring 33 on the edge of the limiting frame 22 fits tightly against the connection between the connector 23 and the limiting frame 22, preventing dust and moisture from entering. The limiting plate 31 at the tail of the connecting block 21 prevents the dust cover 32 from falling off due to displacement, achieving connection stability and ease of operation. At the same time, the dustproof structure extends the service life of the connector.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
