Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber combiners, and specifically relates to a beam combining device for a high-coupling optical fiber combiner. Background Art

[0002] The high-coupling optical fiber combiner is an optical fiber device prepared on the basis of a fused tapered fiber bundle (TFB). It can efficiently combine the optical signals in multiple optical fibers and output them into one or more optical fibers. This combining process requires a high coupling efficiency to ensure the effective transmission of optical energy.

[0003] When the existing beam combining device of the optical fiber combiner completes the connection of the optical fibers, it is necessary to pass the optical fibers combined into one through one end of the optical fiber combiner. However, the existing optical fiber combiner does not fix this passed optical fiber, resulting in friction between the outer surface of the optical fiber and the inner wall of the optical fiber combiner, thus causing wear on the surface of the optical fiber. And once the optical fiber shakes, it will affect the connected part of the optical fibers inside the optical fiber combiner, causing the optical fiber to break. Therefore, it needs to be improved.

The right side of the movable rod 11 is hinged with an articulated rod 13. The right end of the articulated rod 13 is hinged with the left end of the movable plate 5.

[0023] Due to the design of the first clamping block 7 and the second clamping block 8, the first clamping block 7 and the second clamping block 8 can clamp and fix the optical fiber, thereby avoiding the occurrence of situations such as the connection point breaking due to the movement of the optical fiber after beam combination. The operator can push the push-pull rod 10 to the right, so that the movable rod 11 moves to the right, and then the articulated rod 13 drives the two movable plates 5 to move away from each other along the outer surface of the round rod 4, and then the mounting plate 6 and the first clamping block 7 move away from each other.

[0024] Among them, a first round hole 14 is opened on the left side of the housing 1, and a second round hole 15 is opened on the right side of the housing 1.

[0025] As a technical optimization scheme of the present utility model, an operator can insert multiple optical fibers into the interior of the housing 1 through the first round hole 14, and after beam combination, pass through the second round hole 15.

[0026] Among them, side plates 16 are fixedly installed on both the front and rear sides of the top cover 2, and mounting blocks 17 are fixedly installed on both the front and rear sides of the top cover 2.

[0027] As a technical optimization scheme of the present utility model, the number of the mounting blocks 17 is two, and the sizes of the two mounting blocks 17 are the same.

[0028] Among them, sliding rods 18 are fixedly installed at both the left and right ends of the mounting block 17, the other ends of the sliding rods 18 are fixedly connected to the outer surface of the side plate 16, and sliders 19 are movably sleeved on the outer surfaces of the sliding rods 18.

[0029] As a technical optimization scheme of the present utility model, the outer surfaces of the sliding rods 18 are smooth, so that the sliders 19 can move more smoothly on the outer surfaces of the sliding rods 18.

[0030] Among them, a second spring 20 is fixedly connected to the inner side of the slider 19, the other end of the second spring 20 is fixedly connected to the outer surface of the mounting block 17, and a connecting plate 21 is fixedly connected to the bottom of the slider 19, and the bottom of the connecting plate 21 is movably connected to the top of the top cover 2.

[0031] As a technical optimization scheme of the present utility model, by arranging the second spring 20, the second spring 20 can drive the slider 19 to reset under the action of elastic force recovery after being compressed.

[0032] Among them, a clamping plate 22 is fixedly installed at the bottom of the connecting plate 21, and a push plate 24 is fixedly connected to the outer surface of the clamping plate 22.

[0033] As a technical optimization scheme of the present utility model, an operator can drive the clamping plate 22 to move by pushing the push plate 24.

[0035] As a technical optimization scheme of the present utility model, by arranging the fixing block 23, when the inner surface of the clamping plate 22 contacts the fixing block 23, the housing 1 and the top cover 2 can be fixed.

[0036] The working principle and usage process of the present utility model:

[0037] The operator inserts light through the first round hole 14 into the interior of the housing 1 respectively, and then moves the push-pull rod 10 to the right, so that the push-pull rod 10 drives the movable rod 11 to move to the right. Further, the movable rod 11 can push the two movable plates 5 to move away from each other through the hinge rod 13, so that the mounting plate 6 drives the first clamping block 7 and the second clamping block 8 to move away from each other. At this time, the operator inserts the optical fiber through the second round hole 15 into the interior of the housing 1 to connect the optical fiber. At this time, the operator can release the push-pull rod 10, so that the first spring 12 pulls the movable rod 11 to move to the left under the action of elastic force recovery. Thus, the movable rod 11 drives the two movable plates 5 to move towards each other through the hinge rod 13, and further the first clamping block 7 and the second clamping block 8 move towards each other to clamp and fix the optical fiber, thereby preventing the optical fiber from shaking and rubbing against the inner wall of the second round hole 15, and thus preventing the optical fiber from being damaged.

[0038] When the operator needs to disassemble the top cover 2, the operator can push the two push plates 24 to move towards each other, so that the push plates 24 drive the clamping plates 22 to move towards each other, and further the clamping plates 22 are separated from the contact with the fixed blocks 23, so that the fixing effect between the housing 1 and the top cover 2 can be released, thereby facilitating the operator to disassemble the top cover 2 and improving the working efficiency of the operator.
