Description

Technical Field

[0001] This invention relates to the field of communication device technology, and more specifically to an optical fiber mount. Background Technology

[0002] Optical fibers possess many superior properties, such as water resistance, high temperature resistance, chemical corrosion resistance, resistance to electromagnetic interference and nuclear radiation, electrical insulation, small size, flexibility, and light weight. This allows them to be used in inaccessible areas (such as high-temperature zones), areas harmful to humans (such as nuclear radiation zones), or environments with complex electromagnetic conditions. Fiber optic probes offer numerous advantages, including high sensitivity, fast transmission speed, large information capacity, and wide applicability.

[0003] The fiber optic probe is the signal receiving part of a confocal microscopy system. A confocal microscopy system generally consists of a light source, probe and transmission elements, photodetector, and signal processing system. In order to obtain better image quality, the fiber optic probe needs to be able to accurately and stably connect with the fiber optic mount.

[0004] The prior art discloses an optical fiber holder, including a base and a fixing component. The fixing component fixes an external optical fiber to the base. The base includes a substrate and a fixing post disposed on the surface of the substrate. The fixing component is a nut, which is connected to the fixing post by a thread. That is, when the optical fiber is inserted into the through hole of the fixing post, the nut is screwed down on the outside of the fixing post to make the fixing post clamp the optical fiber inside, and fix the optical fiber to the base by the fixing post.

[0005] However, in the aforementioned fiber optic mount, the fiber optic cable is inserted into the through hole of the fixing post, and the fixing post is secured to fix the fiber optic cable by fixing components. This poses a risk that the fiber optic cable may slide in the through hole when subjected to force. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is that in the prior art, the optical fiber holder inserts the optical fiber into the through hole of the fixing post, and the fixing post is fastened by the fixing component to fix the optical fiber, which makes the optical fiber risk sliding in the through hole after being subjected to force.

[0007] Therefore, the present invention provides an optical fiber socket, comprising:

[0008] The main body has through holes suitable for inserting optical fibers;

[0009] An optical fiber fixing assembly is disposed on the main body. The optical fiber fixing assembly includes a rotating component and several locking components. One end of any locking component passes through the main body and is disposed in the through hole. The other end of the locking component is connected to the rotating component.

[0010] The outer end cap is rotatably connected to the main body and connected to the rotating component. The outer end cap can rotate relative to the main body under the action of an external force to drive the rotating component to rotate, thereby driving the locking component to move closer to or away from the optical fiber to fix or release the rotation state of the optical fiber.

[0011] Optionally, the main body is provided with a plurality of limiting slots, and the locking member is provided with a limiting block adapted to the limiting slots. The locking member is disposed in the limiting slots, and in the rotating state, the locking member slides relative to the limiting slots to move closer to or further away from the optical fiber.

[0012] Optionally, the rotating component has a planar helical thread on the side near the locking component, and the locking component has a plurality of arc-shaped grooves adapted to the planar helical thread on the side near the rotating component. In the rotating state, the rotating component is driven to slide relative to the limiting through groove by the planar helical thread adapting to the arc-shaped grooves.

[0013] Optionally, the width of the arc-shaped groove is greater than the width of the planar helical thread.

[0014] Optionally, the optical fiber fixing assembly includes a plurality of rotating columns, one end of which is inserted into a first groove formed on the rotating component, and the other end of which passes through a through groove on the outer end cover, so that the outer end cover drives the rotating component to move.

[0015] Optionally, a second groove is provided on one side of the first groove, the second groove being less deep than the first groove, and the first groove and the second groove being smoothly transitioned, so that the rotating column in the first groove moves from the first groove to the second groove under the drive of the outer end cap, thereby squeezing the rotating component.

[0016] Optionally, the fiber fixing assembly further includes an elastic element disposed between the outer end cap and the rotating column, and the elastic element has an elastic force that drives the rotating column to move toward the rotating component.

[0017] Optionally, the fiber optic socket also includes:

[0018] A limiting plate is connected to the main body. The limiting plate has a limiting opening groove with one end open. The groove wall near the closed end of the limiting opening groove is recessed inward to form a limiting part.

[0019] The stop is elastic and one end is fixedly connected to the outer end cap.

[0020] A rotating component includes a main body and an extension. The main body is rotatably connected to an outer end cap. A first limiting part and a second limiting part are provided on one side of the main body. The other end of the stop component is adapted to abut against the first limiting part or the second limiting part.

[0021] The movable column is movably connected to the extension.

[0022] In the rotating state, the other end of the stop member abuts against the first limiting part, and the rotating member drives the moving column to enter from the opening end of the limiting opening groove until the moving column enters the limiting part to restrict the rotation of the outer end cover. Alternatively, the other end of the stop member abuts against the second limiting part, and the rotating member drives the moving column to exit from the opening end of the limiting opening groove to unlock the restriction on the outer end cover.

[0023] Optionally, the fiber optic mount further includes a bearing component and an end cap fixing component. The bearing component is sleeved on the main body near the end cap, and the end cap fixing component is located between the bearing component and the end cap.

[0024] Optionally, the fiber optic mount also includes a base sleeve disposed within the main body, and one end of the base sleeve is provided with a limiting hole adapted to fit with the fixed end of the fiber optic cable.

[0025] The technical solution provided by this invention has the following advantages:

[0026] 1. This invention provides an optical fiber holder, comprising a main body, an optical fiber fixing assembly, and an outer end cap. The main body has a through hole suitable for inserting an optical fiber. The optical fiber fixing assembly is disposed on the main body and includes a rotating component and several locking components. One end of any locking component passes through the main body and is disposed in the through hole. The other end of the locking component is connected to the rotating component. The outer end cap is rotatably connected to the main body and to the rotating component. The outer end cap has the ability to rotate relative to the main body under the action of an external force, thereby driving the rotating component to rotate and driving the locking component to move towards or away from the optical fiber, thereby fixing or releasing the rotational state of the optical fiber.

[0027] This fiber optic connector features a fiber optic fixing assembly on its main body. This assembly includes a rotating component and several locking components. One end of each locking component passes through the main body and is positioned within a through-hole. The other end of the locking component is connected to the rotating component. An outer end cap is rotatably connected to the main body and is also connected to the rotating component. After the fixed end of the fiber optic cable is inserted into the through-hole in the main body, rotating the outer end cap causes the rotating component to rotate. The rotating component then drives the locking component to move closer to the fiber optic cable, thus fixing the fixed end of the fiber optic cable and preventing it from sliding under force within the through-hole of the main body. By rotating the outer end cap in the opposite direction, the locking component moves away from the fiber optic cable, thereby releasing the fixed end of the fiber optic cable.

[0028] 2. The present invention provides an optical fiber holder, wherein the rotating member is provided with a planar helical thread on the side near the locking member, and the locking member is provided with a plurality of arc-shaped grooves adapted to the planar helical thread on the side near the rotating member. In the rotating state, the rotating member is driven to slide relative to the limiting through groove by the planar helical thread adapting to the arc-shaped grooves.

[0029] The fiber optic holder of this structure has a planar helical thread on the side of the rotating component near the locking component, and several arc-shaped grooves on the side of the locking component near the rotating component that are adapted to the planar helical thread. Since the locking component is set in the limiting through groove on the main body, the planar helical thread can slide in the arc-shaped groove by rotating the rotating component, thereby driving the locking component to move closer to or away from the fiber optic cable to fix or loosen the fiber optic cable.

[0030] 3. The present invention provides an optical fiber holder, wherein the width of the arc-shaped groove is greater than the width of the planar helical thread.

[0031] Because the planar spiral thread of this fiber optic holder is spiral, the inner and outer rings have different curvatures. By setting the width of the arc-shaped groove to be greater than the width of the planar spiral thread, it is possible to prevent the locking element from getting stuck on the inner thread of the planar spiral thread.

[0032] 4. The present invention provides an optical fiber holder, wherein a second groove is provided on one side of the first groove, the depth of the second groove is less than that of the first groove, and the first groove and the second groove are smoothly transitioned, so that the rotating column in the first groove moves from the first groove to the second groove under the drive of the outer end cap, so as to squeeze the rotating component.

[0033] The fiber optic mount of this structure has a first groove and a second groove, with the second groove being less deep than the first groove and a smooth transition between the first and second grooves. This allows the rotating column in the first groove to move from the first groove to the second groove under the influence of the outer end cover when the outer end cover is rotated, thereby squeezing the rotating component and enabling the rotating component to fit tightly against the locking component.

[0034] 5. The present invention provides an optical fiber holder, further comprising a limiting plate, a stop member, a rotating member, and a movable column. The stop member is elastic, one end of which is fixedly connected to the outer end cover, and the other end of which is adapted to abut against a first limiting portion or a second limiting portion. The rotating member comprises a main body and an extension portion. The main body is rotatably connected to the outer end cover, and a first limiting portion and a second limiting portion are provided on one side of the main body. The movable column is movably connected to the extension portion. When fixing the optical fiber, the stop member abuts against the first limiting portion, and the rotating member drives the movable column to enter from the opening end of the limiting slot until the movable column enters the limiting portion, thereby restricting the rotation of the outer end cover. When releasing the optical fiber, the stop member abuts against the second limiting portion, and the rotating member drives the movable column to exit from the opening end of the limiting slot, thereby unlocking the restriction on the outer end cover.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0061] Example

[0062] This embodiment provides an optical fiber mount, such as Figures 1 to 4 As shown, it includes a main body 1, a rotating component 3, a locking component 4, an outer end cap 5, three rotating pillars 6, an elastic component 7, and a base sleeve 10. The main body 1 has a through hole suitable for inserting an optical fiber 2. During installation, the fixed end of the optical fiber 2 is inserted into the through hole, and the outer end cap 5 is rotated to drive the locking component 4 to move toward the fixed end of the optical fiber 2, thereby clamping the fixed end of the optical fiber 2.

[0063] Specifically, such as Figure 2 and Figure 3 As shown, three limiting grooves 11 are evenly arranged at the lower part of the main body 1. The side walls of the limiting grooves 11 are recessed inward to form sliding grooves. A limiting block 41 is provided on each side of the locking member 4. The limiting block 41 is set in the sliding groove and can slide along the length of the sliding groove. The outer surface of the upper part of the main body 1, which has a cylindrical structure, is provided with three rectangular grooves. Correspondingly, as Figure 3 As shown, a bent abutment portion is provided above the locking member 4, and the abutment portion extends towards the main body 1. During installation, when the limiting blocks 41 on both sides of the locking member 4 are engaged in the limiting through groove 11, the bent abutment portion can be inserted into the rectangular through groove. It can be understood that by moving the three locking members 4 towards the main body 1 in the sliding groove, the bent abutment portion of the three locking members 4 is engaged in the fixed end of the optical fiber 2, thereby clamping the fixed end of the optical fiber 2.

[0064] In other embodiments, the number of locking members 4 may also be different, and correspondingly, the number of rectangular through slots and limiting through slots 11 also changes with the number of locking members 4.

[0065] Furthermore, such as Figure 3 and Figure 4 As shown, a rotating component 3 is also fitted onto the main body component 1, such as... Figure 5 and Figure 7As shown, the rotating part 3 has a planar helical thread 31 on the side near the locking part 4, and the locking part 4 has several arc-shaped grooves 42 that are adapted to the planar helical thread 31 on the side near the rotating part 3. Since the locking part 4 is set in the limiting through groove 11 on the main body 1, the locking part 4 cannot rotate with the rotating part 3. Therefore, when the rotating part 3 rotates, the locking part 4 will slide on the planar helical thread 31 through the arc-shaped grooves 42. Since the planar helical thread 31 is helical, the rotating planar helical thread 31 will drive the locking part 4 to slide along the length direction of the groove. That is, the locking part 4 will move from the outside of the planar helical thread 31 to the inside of the planar helical thread 31 to move closer to the optical fiber 2, or the locking part 4 will move from the inside of the planar helical thread 31 to the outside of the planar helical thread 31 to move away from the optical fiber 2.

[0066] Since the planar helical thread 31 is helical, the inner and outer rings have different curvatures. By setting the width of the arc-shaped groove 42 to be greater than the width of the planar helical thread 31, the locking element 4 can be prevented from getting stuck on the inner ring of the planar helical thread 31.

[0067] Furthermore, such as Figure 5 and Figure 6 As shown, the rotating component 3 has three first grooves 32 and three second grooves 33. The depth of the second grooves 33 is less than that of the first grooves 32, and there is a smooth transition between the first grooves 32 and the second grooves 33. Figure 4 As shown, the outer end cover 5 has three through holes on its side wall. The rotating column 6 passes through the through holes and its bottom end passes through the through holes and is located in the first groove 32 or the second groove 33. Thus, when the outer end cover 5 rotates, the three rotating columns 6 can drive the rotating component 3 to rotate, thereby driving the locking component 4 to slide in the limiting through groove 11.

[0068] like Figure 3 and Figure 4 As shown, the fiber optic 2 fixing assembly also includes an elastic element 7, which is located between the outer end cap 5 and the rotating column 6. The elastic element 7 has an elastic force that drives the rotating column 6 to move towards the rotating component 3, thereby squeezing the rotating component 3 through the rotating column 6, so that the planar helical thread 31 on the rotating component 3 and the arc-shaped groove 42 on the locking component 4 remain in contact, preventing the planar helical thread 31 from disengaging from the arc-shaped groove 42. The elastic element 7 is a spring sheet. Based on the principle of three points forming a plane, the three internal rotating columns 6 can transmit torque to the spring sheet more stably and efficiently. Compared to a helical spring, the spring sheet can transmit torque to the three rotating columns 6 more evenly.

[0069] Furthermore, when the outer end cap 5 is rotated so that the three locking pieces 4 abut against the fixed end of the optical fiber 2, the rotating piece 3 stops rotating. At this time, the outer end cap 5 is rotated further so that the rotating column 6 slides from the first groove 32 into the second groove 33. Since the depth of the second groove 33 is less than that of the first groove 32, the rotating column 6 will press the elastic piece 7 upward, so that the force applied by the elastic piece 7 to the rotating column 6 increases, thereby further increasing the pressure on the rotating piece 3.

[0070] like Figure 9 As shown, the fixed end of optical fiber 2 is triangular in shape, and the pointed corner of the fixed end of optical fiber 2 is provided with a chamfered bevel. Correspondingly, the bent abutment part on the locking member 4 also has a chamfer on the side near the fixed end of optical fiber 2. Figure 8 As shown, the base sleeve 10 has a triangular through hole inside that matches the shape of the fixed end of the optical fiber 2. The base sleeve 10 is set inside the main body 1 to ensure that after the fixed end of the optical fiber 2 is inserted into the main body 1, the sharp corner of the fixed end of the optical fiber 2 is aligned with the three locking pieces 4, and the upper surface of the fixed end of the optical fiber 2 is higher than the lower surface of the three locking pieces 4. When the locking piece 4 moves towards the fixed end of the optical fiber 2 under the action of the outer end cover 5, the chamfer on the bent abutment part slides towards the chamfer at the sharp corner of the fixed end. Since the upper surface of the fixed end of the optical fiber 2 is higher than the lower surface of the three locking pieces 4, when the chamfer on the bent abutment part moves to the chamfer at the sharp corner of the fixed end, it can exert a downward squeezing force on the fixed end of the optical fiber 2. Since the upper side of the fixed end of the optical fiber 2 is restricted by the periphery of the triangular through hole inside the base sleeve 10 and cannot move downward, the optical fiber 2 can be fixed inside the main body 1. According to the principle of triangle stability, setting three locking parts 4 can make the force of pressing the fiber 2 bundle more uniform and less prone to skewing.

[0071] like Figure 5 and Figure 9 As shown, a conductive element 101 is provided inside the base sleeve 10. After the optical fiber 2 is fixed inside the main body 1, one end of the conductive element 101 is electrically connected to the optical fiber 2, and the other end is provided outside the base sleeve 10, so as to facilitate the connection of the optical fiber 2 with external equipment.

[0072] like Figures 2 to 4 As shown, the fiber optic mount also includes a bearing component 91 and an end cap fixing component 92. The bearing component 91 is sleeved on the end of the main body 1 near the outer end cap 5. The end cap fixing component 92 is located between the bearing component 91 and the outer end cap 5. The bearing component 91 is installed inside the outer end cap 5, which effectively reduces friction and makes rotation easier.

[0073] like Figure 10 and Figure 11As shown, a connecting block protrudes from the periphery of the outer end cover 5. The fiber optic base also includes a limiting plate 81, a stop member 82, a rotating member 83, and a moving column 84. The limiting plate 81 is connected to the main body 1. The limiting plate 81 has a limiting opening groove with one end open. The groove wall near the closed end of the limiting opening groove is recessed inward to form a limiting part. The rotating member 83 includes a main body 831 and an extension 832. The main body 831 is rotatably connected to the outer end cover 5. A first limiting part 833 and a second limiting part 834 are provided on one side of the main body 831. The other end of the stop member 82 is adapted to abut against the first limiting part 833 or the second limiting part 834. One end of the stop member 82 is fixedly connected to the outer end cover 5. The other end of the stop member 82 is adapted to abut against the first limiting part 833 or the second limiting part 834. The moving column 84 is movably connected to the extension 832.

[0074] like Figure 10 As shown, when the outer end cover 5 rotates along the p direction in the figure, the outer end cover 5 will drive the moving column 84 from the opening end of the limiting opening groove into the limiting opening groove. The opening end of the limiting opening groove will block the moving column 84. Therefore, when the moving column 84 moves to the opening of the limiting opening groove, since the outer end cover 5 continues to rotate, the extension 832 will drive the main body 831 to move relative to the connecting block in the opposite direction of the p direction, that is... Figure 10 In the counterclockwise direction, because the stop 82 is elastic and abuts against the surface of the first limiting part 833, and the first limiting part 833 is a sloped surface, when the main body 831 moves relative to the connecting block in the opposite direction of the p direction, the stop 82 will move towards... Figure 10 The left side of the middle bends and the contact point with the first limiting part 833 moves upward, that is, the stop member 82 will give the main body part 831 a force to rotate in the p direction. When the moving column 84 enters the limiting opening groove under the drag of the outer end cover 5 and reaches the limiting part provided on the bottom wall of the limiting opening groove, since the limiting part is lower than the bottom wall of the limiting opening groove, the moving column 84 will enter the limiting part under the action of the stop member 82, thereby preventing the outer end cover 5 from rotating after losing external force.

[0075] When the outer end cap 5 rotates in the opposite direction of direction p in the figure, that is, when the optical fiber 2 is to be released, similarly, since the moving column 84 is restricted by the limiting part and will not rotate with the outer end cap 5, the extension part 832 will drive the main body part 831 to move relative to the connecting block in the direction p until the stop 82 enters the second limiting part 834. The second limiting part 834 is a slot. When the stop 82 enters the second limiting part 834, the outer end cap 5 rotates in the opposite direction of direction p in the figure, which will pull the moving column 84 out of the limiting part. After the moving column 84 is out of the limiting part, it will move into the bottom wall of the limiting opening groove. The bottom of the slot is set to be higher than the first limiting part. At the bottom of 833, the length of the hook where the stop 82 contacts the main body 831 is greater than the second limiting depth. When the stop 82 enters the second limiting part 834, the stop 82 will bend to the left. After the moving column 84 moves out of the limiting opening slot, the stop will pull the main body 831 to rotate along the p direction until the moving column 84 moves to the height it was at when it was in the limiting part, that is, on the side where the opening end of the limiting opening slot is away from the outer end cover 5. This is so that when the outer end cover 5 rotates along the p direction in the figure, the opening end of the limiting opening slot will block the moving column 84, so that the extension 832 drives the main body 831 to move relative to the connecting block in the opposite direction of the p direction. Thus, when the outer end cover 5 rotates along the p direction in the figure and rotates in the opposite direction of the p direction in the figure, the limiting plate 81, the stop 82, the rotating member 83, and the moving column 84 can lock and release the outer end cover 5.

[0076] In this embodiment, the fiber optic socket is operated by first inserting the fixed end of the fiber optic cable 2 into the main body 1 according to the limiting hole of the base sleeve 10, and then... Figure 1 Rotating the outer end cap 5 in the middle p direction causes the rotating component 3 to rotate via the rotating column 6. The rotating component 3 engages with the arc-shaped groove 42 on the locking component 4 via the planar spiral thread 31 at its bottom, thereby moving the locking component 4 towards the optical fiber 2 until the moving column 84 enters the limiting part in the limiting opening groove, at which point the locking component 4 completely locks the fixed end of the optical fiber 2. When it is necessary to remove the optical fiber 2, follow the... Figure 1 Rotate the outer end cover 5 in the opposite direction of the p direction, move the column 84 away from the limiting part in the limiting opening groove, and the outer end cover 5 drives the locking member 4 to move away from the optical fiber 2 until the locking member 4 disengages from the fixed end of the optical fiber 2, and then pull out the optical fiber 2.

[0077] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
