Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber optic patch cord technology, specifically a multimode MPO patch cord clamping and fixing device. Background Technology
[0002] Multimode MPO jumpers have a 50 or 62.5µm fiber core and an outer sheath. When placed on the corresponding equipment, they need to be routed according to a certain path to avoid excessive bending. The traditional method of fixing the jumpers is to use a limiting block to limit and engage them. When using this method, the multimode MPO jumper and the slot are in free contact and do not have elastic buffering performance. Therefore, a multimode MPO jumper clamping and fixing device is required.
[0003] Currently, existing multimode MPO patch cord clamping and fixing devices lack physical protection for optical fibers during use. This results in the bending radius of the patch cord being smaller than the minimum bending radius after clamping and fixing, leading to optical signal attenuation or fiber core breakage due to excessive bending. To address this, we propose a multimode MPO patch cord clamping and fixing device. Utility Model Content
[0004] The purpose of this invention is to provide a multimode MPO patch cord clamping and fixing device that has the advantages of physical protection, avoiding excessive bending and uniform tension distribution. It solves the problem that existing multimode MPO patch cord clamping and fixing devices lack physical protection of optical fibers, which causes the bending radius of the patch cord to be smaller than the minimum bending radius after clamping and fixing, resulting in optical signal attenuation or fiber core breakage due to excessive bending.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multimode MPO jumper clamping and fixing device, comprising:
[0006] A substrate, wherein a positioning locking plate is provided on the top of the substrate;
[0007] A multi-angle adjustment groove is formed on the lower inner side of the positioning lock plate. A multi-angle positioning block is inserted into the inner side of the multi-angle adjustment groove. An elastic support rod is fixedly connected to one side of the multi-angle positioning block. An arc-shaped support plate is fixedly connected to one end of the elastic support rod.
[0008] Preferably, springs are fixedly connected to the left and right ends of the inner top of the positioning lock plate and the left and right ends of the top of the base plate, and an arc-shaped pressure plate is fixedly connected to one end of the spring.
[0009] Preferably, an anti-slip pad is adhered to one side of the arc-shaped pressure plate.
[0010] Preferably, the left and right ends of the substrate are provided with first bolts, and the left and right ends of the positioning locking plate are threadedly connected to the substrate with second bolts.
[0011] Preferably, a fixed rod is fixedly connected to one side of the elastic support rod, a torsion spring is fixedly connected to one end of the outer surface of the fixed rod, and an adjusting sleeve sleeved on the outside of the fixed rod is fixedly connected to one end of the torsion spring.
[0012] Preferably, a support arm is fixedly connected to one side of the adjusting sleeve, and an arc-shaped positioning plate is fixedly connected to one end of the support arm.
[0013] Preferably, the arc-shaped positioning plate and the arc-shaped support plate are vertically aligned, and a protective rubber pad is provided on one side of both the arc-shaped positioning plate and the arc-shaped support plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, by compressing the elastic support rod to cause slight deformation, allows the polygonal positioning block to align with the corresponding polygonal adjustment groove. Releasing the pressure on the elastic support rod allows the polygonal positioning block to insert into the corresponding polygonal adjustment groove after the elastic support rod returns to its original position. This enables the elastic support rod to position the arc-shaped support plate, providing partial support for the clamped and fixed jumper cable in the horizontal direction. This ensures that the bending radius of the jumper cable is always greater than its minimum bending radius, preventing optical signal attenuation or fiber core breakage due to excessive bending. Furthermore, it evenly distributes tension, avoiding single-point stress that could cause sheath deformation or damage to the internal optical fiber.
[0016] 2. When the multi-angle positioning block is inserted into the corresponding multi-angle adjustment groove, the tilt angle of the arc-shaped support plate can be adjusted as needed, which is beneficial for people to adjust and use according to the specific situation of the jumper.

[0026] Example 1
[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: a multimode MPO jumper clamping and fixing device, comprising:
[0028] The substrate 1 has a positioning locking plate 2 on its top.
[0029] A multi-angle adjustment groove 402 is formed on the lower inner side of the positioning lock plate 2. A multi-angle positioning block 403 is inserted into the inner side of the multi-angle adjustment groove 402. An elastic support rod 4 is fixedly connected to one side of the multi-angle positioning block 403. An arc-shaped support plate 401 is fixedly connected to one end of the elastic support rod 4.
[0030] Springs 301 are fixedly connected to the left and right ends of the top inner side of the positioning locking plate 2 and the left and right ends of the top of the base plate 1. An arc-shaped pressure plate 3 is fixedly connected to one end of the spring 301. An anti-slip pad 302 is glued to one side of the arc-shaped pressure plate 3. First bolts 101 are provided at both ends of the base plate 1. Second bolts 201 are threadedly connected between the left and right ends of the positioning locking plate 2 and the base plate 1.
[0031] This technical solution: By using spring 301 and arc-shaped pressure plate 3, and with the assistance of anti-slip pad 302, the multimode MPO jumper can be fixed for wiring. This provides a certain degree of elasticity and buffering in the vertical direction, especially when the multimode MPO jumper is pulled vertically during wiring, preventing damage. After the elastic support rod 4 undergoes slight deformation by squeezing, the polygonal positioning block 403 aligns with the corresponding polygonal adjustment groove 402. Releasing the pressure on the elastic support rod 4 allows the polygonal positioning block 403 to insert into the corresponding polygonal adjustment groove after the elastic support rod 4 returns to its original position. Within the slot 402, the position of the arc-shaped support plate 401 can be positioned by the elastic support rod 4. When the polygonal positioning block 403 is inserted into the corresponding polygonal adjustment groove 402, the tilt angle of the arc-shaped support plate 401 can be adjusted as needed. This provides partial support for the clamped and fixed jumper in the horizontal direction, ensuring that the bending radius of the jumper is always greater than the minimum bending radius of the jumper (minimum bending radius: ≥30mm in dynamic mode and ≥15mm in static mode). This avoids optical signal attenuation or fiber core breakage due to excessive bending and evenly distributes the tension, preventing single-point stress from causing sheath deformation or damage to the internal optical fiber.
[0032] Example 2
[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a fixed rod 5 is fixedly connected to one side of the elastic support rod 4. A torsion spring 501 is fixedly connected to one end of the outer surface of the fixed rod 5. An adjusting sleeve 502 sleeved on the outside of the fixed rod 5 is fixedly connected to one end of the torsion spring 501. A support arm 504 is fixedly connected to one side of the adjusting sleeve 502. An arc-shaped positioning plate 503 is fixedly connected to one end of the support arm 504. The arc-shaped positioning plate 503 and the arc-shaped support plate 401 are vertically aligned, and a protective rubber pad is provided on one side of both the arc-shaped positioning plate 503 and the arc-shaped support plate 401.
[0034] This technical solution works as follows: When the support arm 504 drives the adjusting sleeve 502 to flip upward at one end of the outer surface of the fixed rod 5, the torsion spring 501 will contract and pre-tighten on the outer surface of the fixed rod 5. After the jumper cable is placed on the top of the arc-shaped support plate 401, the support arm 504 is released. The contracted and pre-tightened torsion spring 501 will drive the support arm 504 and the arc-shaped positioning plate 503 to flip in the opposite direction through the adjusting sleeve 502. In this way, with the cooperation of the arc-shaped support plate 401 and the protective rubber pad, the position of the jumper cable can be limited, ensuring the stability of the jumper cable.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
