Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic patch cord technology, specifically an anti-interference high-density fiber optic patch cord connection structure. Background Technology
[0002] Optical fiber, short for optical waveguide fiber, is a light transmission tool that utilizes the principle of total internal reflection of light within fibers made of glass or plastic. The principle of fiber optic sensing is as follows: a fiber optic sensing device emits pulsed light into the fiber, while simultaneously collecting the scattered signals returning from the fiber. These signals are then received by the fiber optic sensing system and converted into a spectral distribution. Fiber optic patch cord connections consist of core components and functional layers, and their design must balance optical performance, mechanical stability, and environmental adaptability. The fiber core is the optical signal transmission medium; single-mode fiber has a diameter of 8-10 μm, and multimode fiber has a diameter of 50-62.5 μm, made of high-purity quartz glass.
[0003] In the prior art, such as the waterproof connector for protecting fiber optic patch cords disclosed in Publication No. CN221303626U, a fiber optic sheath is included. A housing is formed through the center of the outer portion of the sheath. A threaded ring is fixedly connected to the center of the left side of the housing. A limiting block is provided inside the threaded ring, penetrating the fiber optic sheath and fixedly connected to the housing. A support block is provided to the left of the threaded ring, through which the fiber optic sheath passes. A second nut is rotatably connected to the center of the right side of the housing. The tight fit between the two rubber blocks, the protective sleeve, and the rubber sheath effectively prevents water from entering the connector. The superabsorbent polymer resin stored inside the housing absorbs any water that enters the connector, maintaining a dry environment inside.
[0004] Existing fiber optic patch cord connection structures can effectively prevent water from entering the connector and maintain a dry environment inside the connector through the tight fit of two rubber blocks and a protective sleeve. However, during use, the connector is directly inserted into the device interface for connection, and the connector has no limiting structure, which makes it easy for the connector to fall off. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given that the existing technology involves directly inserting the connector into the device's interface for connection, and the connector lacks any limiting structure, the connector is prone to detachment.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An anti-interference high-density fiber optic patch cord connection structure includes a connector housing, a first fixing ring fixed on the outer surface of the connector housing, a limiting component for limiting the position of the connector on the right side of the first fixing ring, and a protective component for protecting the connector inside the connector housing.
[0009] The limiting component includes a movable part, which is sleeved on the outside of the connector housing and movably connected to the first fixed ring. A connector is welded to the right side of the movable part. Two slots are symmetrically opened on the outer surface of the connector. One end of each slot is provided with a limiting groove opened on the connector.
[0010] As a further improvement of this utility model, the movable part is provided with a second fixing ring that is fixed to the outer surface of the connector housing.
[0011] As a further improvement of this utility model: a compression spring is fixed to the left side of the second fixing ring and abuts against the inner wall of the movable part.
[0012] As a further improvement of this utility model, the outer surface of the movable part is provided with several anti-slip textures.
[0013] As a further embodiment of this utility model: an optical fiber is connected to the left side of the connector housing, and the outer surface of the optical fiber is provided with a protective soft shell that is fixedly connected to the connector housing.
[0014] As a further embodiment of this utility model: the protective component includes an anti-interference layer, which is fixed inside the connector housing, and the inner wall of the anti-interference layer is provided with a reinforcing inner core that is fixedly connected to the connector housing.
[0015] As a further improvement of this utility model: an optical fiber plug is fixed on the right side of the connector housing, and a protective shell is installed on the outside of the optical fiber plug.
[0016] As a further improvement of this utility model: two connecting rods are fixed on the left side of the protective shell, and the ends of the two connecting rods are inserted into fixing holes opened on the connector shell.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. In this utility model, the locking post of the device interface is inserted into the limiting groove, and then the movable part is manually released. During the process of the compression spring extending and resetting itself, the movable part is pushed closer to the first fixed ring, so that the limiting groove on the connector is locked with the locking post of the device interface, thereby effectively reducing the possibility of the connector falling off.
[0019] 2. The anti-slip texture on the movable parts of this utility model can play an anti-slip role, making it convenient for staff to perform connection operations. The protective soft shell on the optical fiber line provides a certain degree of protection, and the anti-interference layer inside the connector shell can play an anti-interference role.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0029] Example 1
[0030] Please see Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an anti-interference high-density fiber optic patch cord connection structure, including a connector housing 1, a first fixing ring 2 fixed on the outer surface of the connector housing 1, a limiting component for limiting the connector on the right side of the first fixing ring 2, and a protective component for protecting the connector inside the connector housing 1.
[0031] The limiting component includes a movable part 3, which is sleeved on the outside of the connector housing 1 and is movably connected to the first fixed ring 2. A connector 31 is welded to the right side of the movable part 3. Two slots 32 are symmetrically opened on the outer surface of the connector 31. One end of each slot 32 is provided with a limiting groove 33 opened on the connector 31.
[0032] Specifically, the movable part 3 has a second fixing ring 34 fixed to the outer surface of the connector housing 1 inside, and a compression spring 35 that abuts against the inner wall of the movable part 3 is fixed to the left side of the second fixing ring 34.
[0033] Furthermore, during the extension and reset process of the compression spring 35, the movable part 3 is pushed closer to the first fixed ring 2, so that the limiting groove 33 on the connector 31 is locked with the locking post of the device interface, thereby effectively reducing the possibility of the connector falling off.
[0034] Specifically, the outer surface of the movable part 3 is provided with several anti-slip textures 36.
[0035] Furthermore, the anti-slip texture 36 on the movable part 3 can play an anti-slip role, making it convenient for staff to perform connection operations.
[0036] During use, when connecting, the slot 32 on the connector 31 needs to be aligned with the pin of the device interface. Then, insert it into the connector housing 1 and simultaneously push the movable part 3. This causes the movable part 3 to move the connector 31, allowing the pin of the device interface to be inserted into the slot 32. When the movable part 3 is pushed, it applies pressure to the clamping spring 35, causing the clamping spring 35 to move towards and compress the second fixed ring 34. After the fiber optic plug 62 is fully inserted, rotate the connector housing 1 and the movable part 3. At this time, the pin of the device interface is engaged in the limiting groove 33. Then, manually release the movable part 3. During the extension and reset process of the clamping spring 35, push the movable part 3 closer to the first fixed ring 2, so that the limiting groove 33 on the connector 31 is engaged with the pin of the device interface. This effectively reduces the possibility of the connector falling off. In addition, the anti-slip texture 36 on the movable part 3 provides an anti-slip function, making it convenient for operators to perform connection operations.
[0037] In summary, when the anti-interference high-density fiber optic patch cord connection structure is in use, during the extension and reset process of the compression spring 35, the movable part 3 is pushed closer to the first fixed ring 2, so that the limiting groove 33 on the connector 31 is locked with the locking post of the device interface, thereby effectively reducing the possibility of the connector falling off.
[0038] Example 2
[0039] Please see Figures 1-5 This is the second embodiment of the present utility model.
[0040] Specifically, an optical fiber 4 is connected to the left side of the connector housing 1. The outer surface of the optical fiber 4 is provided with a protective soft shell 5 that is fixedly connected to the connector housing 1. The protective component includes an anti-interference layer 6, which is fixed inside the connector housing 1. The inner wall of the anti-interference layer 6 is provided with a reinforcing inner core 61 that is fixedly connected to the connector housing 1.
[0041] Furthermore, the protective soft shell 5 set on the optical fiber body 4 provides a certain degree of protection, and the anti-interference layer 6 achieves the function of anti-interference.
[0042] Specifically, an optical fiber plug 62 is fixed on the right side of the connector housing 1, and a protective shell 63 is installed on the outside of the optical fiber plug 62.
[0043] Furthermore, the fiber optic plug 62 can be protected by the protective shell 63 provided on the connector housing 1.
[0044] Specifically, two connecting rods 64 are fixed on the left side of the protective shell 63, and the ends of the two connecting rods 64 are inserted into the fixing holes 65 opened on the connector shell 1.
[0045] Furthermore, with the cooperation of the fixing hole 65 and the connecting rod 64, the protective shell 63 can be removed from the connector shell 1.
[0046] In use, the connector housing 1 is placed in a suitable position. The protective shell 63 on the connector housing 1 can protect the fiber optic plug 62, thereby effectively reducing the impact of external collisions on the fiber optic plug 62. In use, with the cooperation of the fixing hole 65 and the connecting rod 64, the protective shell 63 can be removed from the connector housing 1. Then, the fiber optic plug 62 on the connector housing 1 can be connected to the interface of the external device. The protective soft shell 5 on the fiber optic cable 4 provides a certain degree of protection. The anti-interference layer 6 inside the connector housing 1 is a shielding core made of metal, thereby achieving the function of anti-interference. Furthermore, the reinforced inner core 61 can improve the strength of the connector housing 1 and increase its service life.
[0047] In summary, during use, the anti-interference high-density fiber optic patch cord connection structure pushes the movable part 3 closer to the first fixed ring 2 during the extension and reset of the compression spring 35, so that the limiting groove 33 on the connector 31 is locked with the locking post of the device interface, thereby effectively reducing the possibility of the connector falling off. In addition, the anti-slip texture 36 provided on the movable part 3 can play an anti-slip role, making it convenient for staff to perform connection operations. The anti-interference layer 6 provided inside the connector shell 1 is a shielding core made of metal, which achieves the function of anti-interference.
