Description

Technical Field

[0001] This utility model relates to the field of locking structure technology, specifically to a fiber optic connector locking structure. Background Technology

[0002] Currently, broadband has shifted from wired broadband to fiber optic access. Fiber optics has become quite popular due to its advantages of high transmission speed, thin fiber optic cables, and easy installation. When fiber optic access is installed in a user's home, a fiber optic connector is required. The fiber optic connector is an important interface for connecting the external fiber optic line and the user's modem.

[0003] For example, patent CN210954411U discloses an optical fiber connector, including an optical fiber ceramic head, an optical fiber ferrule, an optical fiber connecting threaded sleeve, a spring, an optical fiber tail sleeve, and an adapter. The spring is used to sleeve the optical fiber extending from the optical fiber tail sleeve and passing through the optical fiber ferrule and the optical fiber ceramic head in sequence. The optical fiber connecting threaded sleeve is sleeved on the optical fiber ferrule and the optical fiber ceramic head and is used to connect with the adapter, so that the spring acts between the optical fiber tail sleeve and the optical fiber ferrule. The optical fiber ceramic head is fixed on the optical fiber ferrule. Although this optical fiber connector can reduce the joint compression stress when used for high-power optical fiber connector splicing, in actual use, the tail sleeve and the optical fiber connecting threaded sleeve are generally connected by threads. That is, when fixing the optical fiber on the optical fiber connector, it is necessary to rotate the tail sleeve many times, which is cumbersome and needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber optic connector locking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fiber optic connector locking structure includes a housing with a cavity inside for inserting a fiber optic body. A clamping member is provided on one side of the housing to clamp the fiber optic body. The clamping member includes an upper clamping plate and a lower clamping plate arranged opposite each other. A driving member is slidably provided outside the clamping member to bring the upper and lower clamping plates closer together to clamp the fiber optic body. A connecting member is provided on the housing for connecting the housing and the driving member. A detachable protective sleeve is provided on the side of the driving member away from the housing. The protective sleeve includes a first set and a second set that are spliced ​​together.

[0007] Preferably, the upper clamping plate and the lower clamping plate are provided with first clamping blocks on opposite sides, and the upper clamping plate and the lower clamping plate are also provided with second clamping blocks on opposite sides. The outer walls of the upper clamping plate and the lower clamping plate are provided with first arc surfaces. The driving component includes a connecting sleeve that is slidably disposed outside the upper clamping plate and the lower clamping plate. The inner wall of the connecting sleeve is provided with a connecting cavity, and the inner wall of the connecting cavity is provided with a second arc surface. The connecting sleeve slides on the first arc surface to drive the first clamping block and the second clamping block to move closer to each other.

[0008] Preferably, the connector includes a mounting base located on one side of the housing, a mounting cavity inside the mounting base, a retaining ring at the opening of the mounting cavity, and a connecting ring on the side of the connecting sleeve near the housing, the connecting ring extending into the mounting cavity for connecting the housing and the connecting sleeve.

[0009] Preferably, the first set has a T-groove on the side closest to the connecting sleeve, and the second set has a T-block extending into the corresponding T-groove.

[0010] Preferably, the connecting sleeve is provided with a first annular groove on the side away from the housing, and the first sleeve and the second sleeve are provided with a second annular groove that mates with the first annular groove. The first annular groove and the second annular groove are connected by a thread.

[0011] Preferably, a dust cover is provided on the other side of the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of the driving component, makes it possible to fix the optical fiber body in the housing simply by sliding the driving component outside the upper clamping plate and the lower clamping plate. Compared with the existing ones, this application does not require rotating the driving component multiple times, making it more convenient in actual use.

[0014] This utility model, through the interlocking arrangement of the first and second sets, allows the first and second sets to be disassembled from the drive unit when one of them is damaged, so that the damaged part can be replaced separately without replacing the entire protective cover, thus reducing the waste of resources. Furthermore, during the replacement of the first or second set, there is no need to disassemble the optical fiber body from the housing; the first or second set can be replaced directly on the optical fiber body, making it more convenient.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0027] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0028] Please see Figures 1-2 The optical fiber connector locking structure in this embodiment includes a housing 100, a cavity for inserting the optical fiber body inside the housing 100, and a clamping member on one side of the housing 100 for clamping the optical fiber body.

[0029] The clamping component includes an upper clamping plate 210 and a lower clamping plate 220 arranged opposite to each other. A driving component is slidably provided on the clamping component. The driving component is used to bring the upper clamping plate 210 and the lower clamping plate 220 closer to each other to clamp the optical fiber body. A connecting component is provided on the housing 100. The connecting component is used to connect the housing 100 and the driving component. A detachable protective sleeve is provided on the side of the driving component away from the housing 100. The protective sleeve includes a first set 130 and a second set 131 spliced ​​together.

[0030] In this embodiment, the optical fiber body includes an outer protective layer 140 and an optical fiber 200 disposed inside it. When the optical fiber body is installed in the housing 100, the optical fiber 200 is exposed and extends into the cavity. The upper clamping plate 210 and the lower clamping plate 220 are driven to move closer to each other by the driving component to clamp the optical fiber body located on the outside of the housing 100, so as to realize the installation of the optical fiber body in the housing 100.

[0031] By setting the driving component, when installing the optical fiber body inside the housing 100, it is only necessary to slide the driving component outside the upper clamping plate 210 and the lower clamping plate 220. Compared with the existing ones, this embodiment does not require rotating the driving component multiple times, making the actual operation more convenient.

[0032] The protective sleeve protects the optical fiber body located outside the housing 100, preventing the part of the optical fiber body in contact with the housing 100 from being subjected to force and causing damage.

[0033] The interconnected design of the first set 130 and the second set 131 allows for easy removal of either set 130 or set 131 from the drive unit when either is damaged, enabling individual replacement of the damaged portion without replacing the entire protective sleeve. This reduces resource waste. Furthermore, during the replacement of set 130 or set 131, the fiber optic body does not need to be removed from the housing 100; it can be directly replaced on the fiber optic body, making the process more convenient.

[0034] Combination Figure 2 As shown, in this embodiment, a first clamping block 211 is provided on the opposite side of the upper clamping plate 210 and the lower clamping plate 220, and a second clamping block 212 is also provided on the opposite side of the upper clamping plate 210 and the lower clamping plate 220. A first arc surface is provided on the outer side wall of both the upper clamping plate 210 and the lower clamping plate 220. The driving component includes a connecting sleeve 120 slidably disposed outside the upper clamping plate 210 and the lower clamping plate 220. A connecting cavity is provided on the inner wall of the connecting sleeve 120, and a second arc surface is provided on the inner wall of the connecting cavity. The connecting sleeve 120 slides on the first arc surface to drive the first clamping block 211 and the second clamping block 212 to move closer to each other.

[0035] In this embodiment, the second clamping block 212 is used to abut against the end wall of the outer protective layer 140 during actual use, thereby limiting the length of the optical fiber 200 extending into the cavity. The first clamping block 211 is used to squeeze the outer wall of the optical fiber body when the upper clamping plate 210 and the lower clamping plate 220 are close to each other, thereby completing the fixation of the optical fiber body in the housing 100.

[0036] Specifically, the upper clamping plate 210 and the lower clamping plate 220 are made of materials with a certain deformation, such as plastic. As a result, when the connecting sleeve 120 moves along the length of the upper clamping plate 210 and the lower clamping plate 220, the second arc surface can squeeze the first arc surface, causing the upper clamping plate 210 and the lower clamping plate 220 to move closer to each other.

[0037] Combination Figure 3 As shown, in this embodiment, the connector includes a mounting base 110 disposed on one side of the housing 100, a mounting cavity 300 provided in the mounting base 110, and a retaining ring 301 provided at the opening of the mounting cavity 300; a connecting ring 310 is provided on the side of the connecting sleeve 120 near the housing 100, and the connecting ring 310 extends into the mounting cavity 300 for connecting the housing 100 and the connecting sleeve 120.

[0038] In this embodiment, the connecting sleeve 120 is made of plastic. When it is necessary to fix the connecting sleeve 120 to the housing 100, the connecting sleeve 120 is moved so that the connecting ring 310 extends into the mounting cavity 300. The connecting ring 310 is squeezed and reduced by the retaining ring 301 and enters the mounting cavity 300. After it is removed from the retaining ring 301, the connecting ring 310 returns to its original size. An interference fit is formed between the connecting ring 310 and the retaining ring 301, so that the connecting sleeve 120 will not easily detach from the housing 100. When it is necessary to remove the connecting sleeve 120 from the housing 100, the connecting ring 310 can be deformed by pulling the connecting sleeve 120 so that it can be removed from the opening of the mounting cavity 300.

[0039] Combination Figure 4 As shown, in this embodiment, the first set 130 is provided with a T-shaped groove 410 on the side near the connecting sleeve 120, and the second set 131 is provided with a T-shaped block 411 extending into the corresponding T-shaped groove 410.

[0040] In this embodiment, the T-slot 410 is opened along the axial direction of the connecting sleeve 120 on the side where the first set 130 and the second set 131 cooperate. When connecting the first set 130 and the second set 131, the T-block 411 can be aligned with the T-slot 410 and slid in. At this time, the first set 130 and the second set 131 are connected in the circumferential direction, so that they can protect the outer protective layer 140.

[0041] Combination Figure 1-5 As shown, in this embodiment, the connecting sleeve 120 is provided with a first annular groove 400 on the side away from the housing 100, and the protective sleeve is provided with a second annular groove 500 that cooperates with the first annular groove 400. The first annular groove 400 and the second annular groove 500 are connected by threads.

[0042] In this embodiment, the first annular groove 400 is provided with an external thread, and the second annular groove 500 is provided with an internal thread. When it is necessary to install the first set 130 and the second set 131 on the connecting sleeve 120, the first annular groove 400 is aligned with the second annular groove 500, and the first set 130 and the second set 131 that have been spliced ​​are rotated to connect the first set 130 and the second set 131 to the connecting sleeve 120 through the thread.

[0043] When the protective cover is damaged, it can be removed by threading, and the two can be separated by sliding the first set 130 and the second set 131, so that the damaged part can be replaced.

[0044] Combination Figure 1 As shown, in this embodiment, a dust cover 101 is provided on the other side of the housing 100.

[0045] In this embodiment, the dust cover 101 prevents external dust from entering the housing 100, thereby improving the dustproof effect of the housing 100.

[0046] In actual use, when fixing the optical fiber body within the housing 100, the optical fiber 200 is inserted into the cavity through the upper clamping plate 210 and the lower clamping plate 220. When the end of the outer protective layer 140 contacts the second clamping block 212, the outer protective layer 140 stops moving. At this time, the connecting sleeve 120 moves along the length direction of the upper clamping plate 210 and the lower clamping plate 220, causing the second arc surface to press against the first arc surface. The upper clamping plate 210 and the lower clamping plate 220 move closer to each other, ultimately causing the corresponding first clamping block 211 and the corresponding second clamping block 212 to move closer to each other. The first clamping block 211 can clamp the outer protective layer 140, and the second clamping block 212 can fix the optical fiber 200. Thus, the fixing of the optical fiber body within the housing 100 is completed.

[0047] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
