Description

Technical Field

[0001] This invention relates to the field of optical communication equipment technology, and in particular to length setters and cutting devices. Background Technology

[0002] In the field of fiber optic communication, fiber optic connectors are typically used for the transmission and connection of optical signals between different modules. Optical fibers are threaded through the connector and mated together. Since the dimensions of fiber optic connectors are fixed, the fiber needs to be cut to a specific length before being threaded through. A common method is to fix the fiber to a length setter, then place the length setter on a cutting device. The fixed fit between the length setter and the cutting device achieves the desired length cutting.

[0003] Currently, there are some differences in the mating dimensions between cleaving devices from different companies and the same length setter. This means that after mating, the distance between the cleaving blade on the cleaving device and the length setter varies, resulting in different lengths of cut optical fibers. Therefore, different length setters are needed to match cleaving devices from different companies to solve the problem of inconsistent fiber cutting lengths. However, designing multiple different length setters for a specific optical fiber connector can lead to mismatching errors in actual operation, complicating the process, reducing assembly efficiency, and increasing costs. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, the present invention provides a length-fixing device and a cutting apparatus, and the technical solution adopted is as follows:

[0009] In the mating state, the first side and the second side are located on the same side, and the limiting member has different mating positions with the main body, so that the first side and the second side have different distances.

[0010] In some embodiments of the present invention, the first mating structure is configured as a plurality of first mating holes, each of the first mating holes being at a different distance from the first side surface, and the second mating structure is configured as a raised second protrusion, wherein in the mating state, the second protrusion is inserted into the first mating hole.

[0012] In some embodiments of the present invention, the other side of the main body has an optical fiber mounting slot, an optical cable clamp mounting slot, and an optical cable mounting slot that are connected to each other in sequence.

[0013] In some embodiments of the present invention, the optical fiber mounting slot includes a cladding optical fiber slot and a bare optical fiber slot, the cladding optical fiber slot is located between the bare optical fiber slot and the optical cable clamp mounting slot, and the width of the cladding optical fiber slot is greater than the width of the bare optical fiber slot.

[0014] In some embodiments of the present invention, the optical cable clamping block mounting groove and the optical cable mounting groove have a through-body opening.

[0015] In some embodiments of the present invention, the first side is provided with an extension portion, the width of the extension portion is smaller than the width of the main body, the optical fiber mounting groove extends to the extension portion, the extension portion has a third side side away from the first side side, and in the mating state, the second side side does not extend beyond the third side side.

[0016] The cutting device according to a second aspect of the present invention includes a cutting table and a length setter according to a first aspect of the present invention.

[0018] In some embodiments of the present invention, in the usage state, along the height direction of the cutting device, the bottom surface of the optical fiber mounting groove is lower than the top surface of the optical fiber fixing platform.

[0019] Beneficial effects: By setting the limiting component and the main body to have different mating positions, the second side of the limiting component and the first side of the main body have different displacements under different mating positions. The limiting component can abut against the limiting part on the cutting device, thereby limiting the cutting length of the optical fiber.

[0040] Reference Figures 1 to 12 This invention proposes a length-fixing device 100 and a cutting device 200. The length-fixing device 100 according to a first aspect embodiment includes a main body 110 and a limiting member 120. A first mating structure is provided on one side of the main body 110, and the main body 110 has a first side surface 111. The limiting member 120 has a second mating structure, and the limiting member 120 has a second side surface 121. The first mating structure and the second mating structure are detachably connected, allowing the main body 110 and the limiting member 120 to have a mating state and a separated state. In the mating state, the first side surface 111 and the second side surface 121 are located on the same side, and the limiting member 120 and the main body 110 have different mating positions, resulting in different distances between the first side surface 111 and the second side surface 121. The main body 110 and the limiting member 120 are detachably connected through the first and second mating structures.

[0041] In some embodiments, the first mating structure is configured as a plurality of first mating holes, each of which is at a different distance from the first side 111. The second mating structure is configured as a raised second protrusion. In the mating state, the second protrusion is inserted into the first mating hole, thereby realizing the mating of the limiting block and the main body 110.

[0042] In other embodiments, the second mating structure is configured as a plurality of second mating holes 122, each second mating hole 122 being at a different distance from the second side surface 121, and the first mating structure is configured as a raised first protrusion 112, which is inserted into the second mating hole 122 in the mating state.

[0043] like Figure 6 As shown, the other side of the main body 110 has an optical fiber mounting slot 113, an optical cable clamp mounting slot 114 and an optical cable mounting slot 115 that are connected to each other in sequence.

[0044] like Figures 1 to 7 As shown, the main body 110 is rectangular in shape and has a lower side and a upper side. The fiber optic mounting slot 113, the optical cable clamp mounting slot 114, and the optical cable mounting slot 115 are located on the upper side opposite to the first mating structure. The rectangular main body 110 has a major axis direction and a minor axis direction, that is, the length direction and the width direction of the main body 110. The main body 110 also has a front end region and a rear end region. The fiber optic mounting slot 113 is located in the front end region of the main body 110 and extends through the front end of the main body 110 along the major axis direction. The optical cable mounting slot 115 is located in the rear end region of the main body 110 and extends through the rear end of the main body 110 along the major axis direction. The optical cable clamp mounting slot 114 is located between the fiber optic mounting slot 113 and the optical cable mounting slot 115, and the fiber optic mounting slot 113, the optical cable clamp mounting slot 114, and the optical cable mounting slot 115 are interconnected.

[0045] It is understandable that the first side 111 of the main body 110 is the side of the front end of the main body 110, and the first mating structure is set in the front end area of ​​the lower side of the main body 110.

[0046] It is understandable that when the main body 110 and the limiting member 120 are in a mating state, the lower surface of the main body 110 and the lower surface of the limiting member 120 are coplanar.

[0047] like Figure 6 As shown, specifically, the optical fiber mounting slot 113 includes a cladding fiber slot 116 and a bare fiber slot 117. The cladding fiber slot 116 is located between the bare fiber slot 117 and the optical cable clamp mounting slot 114, and the width of the cladding fiber slot 116 is greater than the width of the bare fiber slot 117.

[0048] In some embodiments, there is a window 118 through the main body 110 between the optical cable clamping block placement groove 114 and the optical cable placement groove 115. Setting the window 118 can save materials and reduce costs.

[0049] like Figure 1 and Figure 2 As shown, the mating structure is configured with multiple second mating holes 122. The first protrusion 112 is a cylinder, and the second mating hole 122 is a circular through hole that mates with the first protrusion 112.

[0050] It is understandable that, in the engaged state, the second side 121 of the limiting member 120 is the side of the front end of the limiting member 120, and the second side 121 is located on the same side as the first side 111, that is, on the front end side of the main body 110.

[0051] like Figure 1As shown, in this embodiment, three first protrusions 112 are provided, arranged side-by-side and spaced apart along the long axis of the main body 110. Three second mating holes 122 are connected to the three first protrusions 112, and the positions of the three second mating holes 122 correspond to the positions of the three first protrusions 112. It can be understood that the number of second mating holes 122 is greater than or equal to the number of first protrusions 112. The three second mating holes 122 form a mating hole group 123. Multiple sets of mating hole groups 123 are provided. In the mating state, the multiple sets of mating hole groups 123 are spaced apart along the width direction of the main body 110, and the distance from each set of mating hole groups 123 to the second side surface 121 along the length direction of the main body 110 is different. By setting the mating hole groups 123 and the first protrusions 112 to form a mating structure, the structure can be made more stable.

[0052] In this embodiment, the distance from each set of mating holes 123 to the second side surface 121 gradually decreases along the length of the main body 110. For example... Figure 1 and Figure 2 As shown, in this embodiment, five sets of mating holes 123 are provided. When each set of mating holes 123 mates with the first protrusion 112, the limiting member 120 and the main body 110 will have different mating positions. Therefore, the limiting member 120 and the main body 110 have multiple different mating positions. Under different mating positions, the second side 121 of the limiting member 120 and the first side 111 of the main body 110 have different displacements. It can be understood that the displacement refers to the shortest distance from the first side 111 to the second side 121.

[0053] like Figure 3 As shown, the mating position of the limiting member 120 and the main body 110 is denoted as A1, and the displacement at this time is denoted as S1.

[0054] like Figure 4 As shown, the mating position of the limiting member 120 and the main body 110 is denoted as A2, and the displacement at this time is denoted as S2.

[0055] like Figure 5 As shown, the mating position of the limiting member 120 and the main body 110 is denoted as A3, and the displacement at this time is denoted as S3.

[0056] like Figure 7 and Figure 8 As shown, in some embodiments, the cutting device 200 further includes a clamping block 130, which is detachably connected to the optical cable clamping block placement groove 114 and fixes the optical cable 300 in place.

[0057] Continue to refer to Figures 8 to 12The cutting device 200 of the second aspect of the present invention includes a cutting table 210, a cutting blade 220, and a length fixer 100 of some of the above embodiments of the present invention. The cutting table 210 includes a positioning area 211, a limiting part 212, and an optical fiber fixing platform 213 arranged in sequence. The cutting device 200 has a use state. In the use state, the length fixer 100 is placed in the positioning area 211, and the second side 121 abuts against the limiting part 212.

[0058] Continue to refer to Figure 8 , Figure 9 In some embodiments, fiber optic fixing platforms 213 are provided on both sides of the cutting blade 220. The cutting device 200 also includes a cover plate 230, which is rotatably connected to the cutting table 210. A fiber optic fixing member 231 is provided on the cover plate 230. The cover plate 230 rotates toward the cutting table 210, and the fiber optic fixing member 231 moves toward the fiber optic fixing platform 213. In use, the fiber optic fixing member 231 and the fiber optic fixing platform 213 limit and fix the fiber optic cable.

[0059] Continue to refer to Figure 8 , Figure 11 , Figure 12 In use, along the height direction (vertical direction) of the cutting device 200, the bottom surface 240 of the fiber optic mounting groove is lower than the top surface 250 of the fiber optic fixing platform. This avoids the problem of fiber breakage due to the difference in height between the two surfaces after the cover plate 230 of the cutting device 200 is closed.

[0060] Continue to refer to Figures 1 to 5 In some embodiments, the first side 111 has a forward-protruding extension 119, the width of which is smaller than the width of the main body 110. The fiber mounting groove 113 extends to the extension 119, and the extension 119 has a third side 140 away from the first side 111. In the mating state, the second side 121 does not extend beyond the third side 140. The optical fiber passes through the fiber mounting groove 113 and is inserted into the fiber fixing platform 213 of the cutting device 200. The design of the extension 119 can avoid the unevenness of the fiber cutting end face caused by a large tilt of the optical fiber.

[0061] During the use of the length setter 100, the mating position of the limiting member 120 and the main body 110 is first adjusted according to the cutting device 200 of different manufacturers. Then, the optical cable 300 passes through the clamping block 130 and is clamped, with the front part of the optical cable 300 forming an exposed bare optical fiber portion 400. The clamping block 130 is placed in the optical cable clamping block mounting groove 114, and the optical cable 300 is located in the optical cable mounting groove 115, while the bare optical fiber portion 400 is located in the optical fiber mounting groove 113. Next, the length setter 100, together with the clamped optical cable 300, is placed on the positioning area 211 of the cutting device 200, and the limiting member 120 abuts against the limiting part 212. The abutting surface of the limiting part 212 does not contact the main body 110, and the bare optical fiber portion 400 extends into the cutting area. The bare optical fiber portion 400 is cut to a fixed length by the cutting blade 220.

[0062] In the existing cutting devices 200 from different manufacturers, the distance between the cutting blade 220 and the limiting part 212 is inconsistent, resulting in different fiber cutting lengths when using the same length setter 100 on different cutting devices 200.

[0063] By setting the limiting member 120 and the main body 110 to have different mating positions, the second side 121 of the limiting member 120 and the first side 111 of the main body 110 have different displacements under different mating positions. The limiting member 120 can abut against the limiting part 212 on the cutting device 200, thereby limiting the cutting length of the optical fiber. The present invention can adjust the displacement by adjusting the mating position of the limiting member 120 on the main body 110, so that the length fixer 100 can be adapted to different cutting devices 200, thereby adjusting the cutting length of the optical fiber, ensuring that the optical fiber length between the length fixer 100 and the cutting blade 220 is consistent, thereby obtaining a consistent optical fiber cutting length.
