Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a protective device that can prevent damage to fiber optic connectors. Background Technology

[0002] Fiber optic connectors are devices that provide detachable (movable) connections between optical fibers. They precisely align the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, and to minimize the impact on the system caused by their intervention in the optical link. These are the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] When fiber optic connectors are in use, the connection point is prone to breakage after the fiber optic cable is stretched, and the glass conduit inside the fiber optic cable may break. This is especially true when the fiber optic cable is installed in broadband upgrades or subsequent installations, and the layout is not reasonable enough, resulting in a lack of protection for the fiber optic connector and the fiber optic cable. To address this problem, we propose a protective device to prevent damage to fiber optic connectors. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a protective device that can prevent damage to fiber optic connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for preventing damage to fiber optic connectors includes a fiber optic connector body, and the protective component includes a housing that snaps into the fiber optic connector body, wherein the protective component is disposed on the housing.

[0007] The protective assembly includes a connecting rod fixedly connected to the housing, a push rod slidably connected to the connecting rod, a C-shaped clip fixedly connected to the upper end of the push rod, a compression spring fixedly sleeved on the push rod and positioned similarly to the connecting rod, and symmetrically arranged clamping rods rotatably connected to the connecting rod. The clamping rods clamp the fiber optic connector body, and a connecting strap is fixedly connected to the ends of the two clamping rods away from the fiber optic connector body, with the connecting strap abutting against the push rod.

[0008] Preferably, an arc-shaped piece is fixedly connected to the upper end of the push rod, and the arc-shaped piece is positioned close to the C-shaped clip, with multiple limiting clips fixedly connected to the arc-shaped piece.

[0009] Preferably, the housing includes an outer frame, an inner frame is slidably connected to the inner wall of the outer frame, the connecting rod is fixedly connected to the inner frame, an elastic sheet is fixedly connected to the inner frame, and a friction block is fixedly connected to the side of the elastic sheet near the fiber optic connector body, and a wedge block is fixedly connected to the side of the outer frame near the elastic sheet.

[0010] Preferably, a limiting groove is formed on the elastic sheet, and a lever is fixedly connected to the wedge block.

[0011] Preferably, the C-shaped card is made of an elastic material, and the inner wall of the C-shaped card is provided with anti-slip grooves.

[0012] Preferably, a connecting rope is fixedly connected to the connecting belt, and the connecting rope is fixedly connected to the push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up a protective component, can use a C-shaped clip to hold the optical fiber, and then use a push rod to fully move the optical fiber. There is a slack at the inlet end of the optical fiber connector body. When the optical fiber is pulled, it can be straightened, thereby avoiding damage to the connection between the optical fiber and the optical fiber connector. When the pulling amplitude is large, the push rod can cause the connecting strip to bend downward, thereby causing the clamp to rotate. The clamp can then cause the elastic clip on the optical fiber connector body to rotate, allowing the optical fiber connector to disconnect from the connected device, ultimately protecting the optical fiber connector.

[0015] This utility model, by setting an arc-shaped piece in conjunction with a limiting card, can protect the bent part of the optical fiber, preventing the glass conduit inside the optical fiber from breaking due to excessive bending angle, thus affecting the propagation of photoelectric signals. By setting an outer frame in conjunction with the inner frame of the kitchen shell, this protective device can be easily installed on the existing optical fiber connector without the need for the optical fiber connector to be adapted for the protective device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A protective device for preventing damage to fiber optic connectors includes a fiber optic connector body 1, and the protective component includes a housing that snaps into the fiber optic connector body 1, wherein the housing is provided with the protective component.

[0023] The protective assembly includes a connecting rod 7 fixedly connected to the housing, a push rod 8 slidably connected to the connecting rod 7, a C-shaped clip 9 fixedly connected to the upper end of the push rod 8, a compression spring 10 fixedly sleeved on the push rod 8, and the compression spring 10 is arranged in a similar manner to the connecting rod 7. A clamping rod 11 symmetrically arranged is rotatably connected to the connecting rod 7. The clamping rod 11 clamps the fiber optic connector body 1. A connecting strap 12 is fixedly connected to the end of the two clamping rods 11 away from the fiber optic connector body 1. The connecting strap 12 is arranged to abut against the push rod 8.

[0024] In this design, the optical fiber is inserted into the optical fiber connector body 1 near the push rod 8, and the C-shaped clip 9 engages with the optical fiber. A curved section of optical fiber is formed at the tail of the optical fiber connector body 1. When the optical fiber is pulled, it straightens and moves the push rod 8 towards the connecting strip 12. After the pulling force disappears, the compression spring 10 drives the push rod 8 back to its initial position, ensuring that the optical fiber still has a certain buffer margin when pulled again. When the pulling force is large enough, the push rod 8 causes the connecting strip 12 to bend, which in turn pulls the two clamping rods 11 to rotate towards each other. The clamp 11 holds the elastic clip on the fiber optic connector body 1 and causes the elastic clip to retract, allowing the fiber optic connector body 1 to separate from the connected device. This prevents damage to the fiber optic connector body 1 or the interface on the connected device, as well as preventing fiber core breakage, thus providing good protection. It should be noted that network devices connected to fiber optic equipment are almost immune to brief disconnections. This type of protection device is mainly used in scenarios where fiber optic lines are easily touched, prioritizing the protection of fiber optic connectors and related equipment.

[0025] Furthermore, an arc-shaped piece 13 is fixedly connected to the upper end of the push rod 8, and the arc-shaped piece 13 is positioned close to the C-shaped clip 9. Multiple limiting clips 14 are fixedly connected to the arc-shaped piece 13.

[0026] The arc-shaped piece 13 is used in conjunction with the limiting card 14 to softly fix the optical fiber and ensure that the optical fiber will not bend too much under the action of the push rod 8, which would damage the glass conduit inside. It should be noted that the optical fiber can slide relative to the C-shaped card 9 and the limiting card 14.

[0027] Furthermore, the housing includes an outer frame 2, an inner frame 3 is slidably connected to the inner wall of the outer frame 2, the connecting rod 7 is fixedly connected to the inner frame 3, an elastic sheet 4 is fixedly connected to the inner frame 3, and a friction block 5 is fixedly connected to the side of the elastic sheet 4 near the fiber optic connector body 1, and a wedge block 6 is fixedly connected to the side of the outer frame 2 near the elastic sheet 4.

[0028] In this design, the user first places the outer frame 2 onto the fiber optic connector body 1, and then pushes the inner frame 3 towards the outer frame 2 until the wedge block 6 abuts against the friction block 5. The wedge block 6 then drives the elastic sheet 4 to move fully towards the fiber optic connector body 1, ensuring that the friction block 5 can clamp the fiber optic connector body 1. This allows the user to install this protective device on the existing fiber optic connector body 1 without modifying the existing fiber optic connector for compatibility.

[0029] Furthermore, a limiting groove is provided on the elastic sheet 4, and a lever 15 is fixedly connected to the wedge block 6;

[0030] The limiting groove is set to limit the wedge block 6 to ensure the limiting effect of the wedge block 6 on the friction block 5. The lever 15 is set to facilitate the user to use the lever 15 to drive the wedge block 6 to elastically deform, so as to separate it from the friction block 5 and then disassemble the protective device.

[0031] Furthermore, the C-shaped card 9 is made of elastic material, and the inner wall of the C-shaped card 9 is provided with anti-slip grooves, wherein the direction of the protective grooves is parallel to the optical fiber line, in order to prevent the optical fiber from directionally detaching from the C-shaped opening of the C-shaped card 9 first.

[0032] Furthermore, a connecting rope 16 is fixedly connected to the connecting belt 12. The connecting rope 16 is fixedly connected to the push rod 8. The connecting rope 16 can relatively fix the push rod 8 and the connecting belt 12, making the cooperation between the push rod 8 and the clamping rod 11 more stable.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
