Description
Technical Field
[0001] This utility model relates to the field of optical fiber connector technology, specifically to an optical fiber connector with a fusion capacitive structure. Background Technology
[0002] With the rapid development of fiber optic communication technology, optical fiber has become a key transmission medium in modern communication networks. Fusion splicing, as a common and mature method for fiber optic installation and maintenance, offers advantages such as low loss and high stability. However, in the aerospace field, due to the special requirements of aviation connectors, direct polishing of fiber optic cables is typically required for connection. This method is not only complex to assemble and maintain, but also often requires the fiber to be returned to the original manufacturer or a repair center in a neighboring country for repair in case of failure. This increases maintenance costs and extends the repair cycle, hindering the widespread adoption of optical fiber. Therefore, a new type of fiber optic connector is designed. Utility Model Content
[0003] This invention provides a fiber optic connector with a fusion capacitive structure, which can solve the problem that the existing aviation plugs and optical fibers are connected by grinding, which has limitations in assembly and maintenance, resulting in high costs and long maintenance cycles.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic connector with a fusion splicing and capacitive structure, comprising a connector assembly and a cable, wherein a fiber optic fusion splicing and capacitive structure is provided between the connector assembly and the cable; the fiber optic fusion splicing and capacitive structure includes a housing, wherein a receiving groove for placing a fusion splicing device is provided inside the housing, a cable fixing device for fixing the cable is provided at one end of the housing, and a fixing sleeve is provided at the other end of the housing; the connector assembly includes a core connector disposed on one side of the housing, and a core connector fixing device is provided at the rear of the core connector. The cable and the core connector are separated by the fusion splicing and capacitive structure, reducing damage to the core connector caused by external forces. Fiber optic splicing and replacement can be performed on-site without returning to the factory or sending to a professional repair center, thus improving the convenience of maintenance.
[0005] Preferably, a connector housing is fitted onto the front outer side wall of the core connector, and the rear part of the connector housing is connected to the fixed sleeve through a sleeve connection part. The sleeve connection part and the fixed sleeve are connected by threads to ensure that the connection between the connector housing and the fixed sleeve is tight and firm, thereby ensuring the stability of the optical fiber connection.
[0006] Preferably, a cover is fixedly provided on the upper side of the housing. The cover can protect the welding device in the receiving tank and prevent dust, debris and other objects from entering the receiving tank and affecting the welding effect.
[0007] Preferably, the upper end face of the housing is provided with screw holes at all four corners, and the cover is provided with through holes corresponding to the screw holes. The bolt passes through the through holes and connects with the screw holes, which can easily fix the cover to the housing and ensure the sealing between the cover and the housing.
[0008] Preferably, the optical fiber of the cable and the optical fiber of the core connector are both inserted into the receiving groove and connected by a fusion splicing device, which is convenient to operate.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] With its simple structure and convenient operation, fiber optic splicing and replacement can be performed on-site without returning to the factory or sending it to a professional repair center, improving maintenance convenience. The fusion receiver structure separates the cable and core connector, reducing damage to the core connector caused by external forces and effectively extending its overall lifespan. The spliced fiber is protected within the fusion receiver structure, with ample space to accommodate the fusion support rod and heat-shrink sleeve, as well as retain the bending radius of the bare fiber after splicing. The separate design of the housing and cover further enhances maintenance convenience. This solution addresses the limitations of existing aviation connectors that use grinding to connect fibers, which leads to high costs and long maintenance cycles. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figure 1-2As shown, this utility model addresses the limitations of existing aviation connectors that use grinding to connect optical fibers, resulting in high costs and long maintenance cycles. The proposed solution is a fiber optic connector with a fusion splice and capacitor structure, comprising a connector assembly 1 and a cable 2. A fiber optic fusion splice and capacitor structure 3 is provided between the connector assembly 1 and the cable 2. The fiber optic fusion splice and capacitor structure 3 includes a housing 31, the cross-sectional area of which is similar to that of the connector assembly 1, facilitating connector access to existing equipment. The housing 31 contains a receiving groove 32 for housing a fusion splicing device. One end of the housing 31 has a cable fixing device 33 for fixing the cable 2, and the other end has a fixing sleeve 34. The connector assembly 1 includes a core connector 11 located on one side of the housing 31. A core connector fixing device 12 is located at the rear of the core connector 11. The fusion splice and capacitor structure separates the cable and the core connector, reducing damage caused by external forces. Fiber optic splicing and replacement can be performed on-site without returning to the factory or a professional repair center, improving maintenance convenience.
[0017] Specifically, a connector housing 13 is fitted onto the front outer side wall of the core connector 11. The rear part of the connector housing 13 is connected to the fixed sleeve 34 through a sleeve connection part 14. The sleeve connection part 14 and the fixed sleeve 34 are connected by threads to ensure that the connection between the connector housing 14 and the fixed sleeve 34 is tight and firm, thereby ensuring the stability of the optical fiber connection.
[0018] In this embodiment, as Figure 1 As shown, a cover 35 is fixedly provided on the upper side of the housing 31. The cover 35 can protect the welding device in the receiving groove 32 and prevent dust, debris and other objects from entering the receiving groove 32 and affecting the welding effect.
[0019] In this embodiment, as Figure 1 and Figure 2 As shown, screw holes 36 are provided at the four corners of the upper end face of the housing 31, and through holes 37 corresponding to the screw holes 36 are provided on the cover 35. The bolt passes through the through holes 37 and connects with the screw holes 36, which can easily fix the cover to the housing and ensure the sealing between the cover and the housing.
[0020] In this embodiment, as Figure 2 As shown, the optical fiber of the cable 2 and the optical fiber of the core connector 11 are both inserted into the receiving groove 32 and connected by a fusion splicing device, which is convenient to operate.
[0021] In this embodiment, as Figure 1As shown, the fusion splicing device is placed in the receiving groove 32 of the fiber optic fusion receiver structure 3. One end of the cable 2 is fixed to one end of the housing 31 by the cable fixing device 33, ensuring that the fiber optic line of the cable 2 passes into the receiving groove 32. The core connector 11 is connected to the core connector fixing device 12. Then, the connector housing 13 is sleeved on the front outer side wall of the core connector 11. Then, the connector housing 13 is connected to the sleeve connection part 14. The fiber optic line of the core connector 11 is also passed into the receiving groove 32. The sleeve connection part 14 is threadedly connected to the fixing sleeve 34. The fiber optic line of the cable 2 and the fiber optic line of the core connector 11 are fused together by the fusion splicing device. The cover 35 is placed on the upper side of the housing 31, so that the through hole 37 on the cover 35 corresponds to the screw hole 36 at the four corners of the upper end face of the housing 31. Then, the bolt is passed through the through hole 37 and connected to the screw hole 36 to fix the cover 35 on the housing 31. During maintenance, only the cover needs to be opened, the jumper wire replaced, and the fusion splicing re-splitting performed.
