Description

Technical Field

[0001] This invention relates to the field of fiber optic connector technology, specifically to a fiber optic connector housing for a smart sensor and its manufacturing method. Background Technology

[0002] Fiber optic communication, with its high bandwidth and strong resistance to electromagnetic interference, provides a high-speed and reliable data transmission channel for smart sensors, greatly improving signal integrity and transmission distance. This enables smart sensors to achieve more accurate real-time data acquisition and remote monitoring in complex environments such as industrial automation, environmental monitoring, and medical equipment. As a key component for achieving fast and reliable optical path connection, the performance of fiber optic connectors directly affects the stability and quality of signal transmission. In existing technologies, common connector housings often use a snap-fit ​​structure for mating and locking. To ensure that the fiber end faces maintain tight contact after mating and compensate for minor axial gaps and deviations, the industry generally incorporates a cylindrical spring (i.e., a spring loading mechanism) inside the connector. This spring typically applies continuous axial pressure to one end of the ceramic ferrule or optical fiber, using its elastic deformation to provide thrust, thereby allowing the end faces of the two optical fibers to automatically adjust and fit tightly during mating, offsetting mechanical tolerances and maintaining stable physical contact. This is the foundation for ensuring low insertion loss and high return loss.

[0003] However, in special operating conditions such as equipment testing, on-site debugging, frequent network configuration changes, or regular maintenance, connectors are required to undergo high-frequency plugging and unplugging operations. Their mechanical components, especially the precision spring mechanisms, will be subjected to repeated cyclic stress. A more significant problem is that in industrial sites, outdoor environments, or high-dust environments, frequent plugging and unplugging inevitably increases the risk of external contaminants (such as dust, oil, and metal shavings) entering the housing. These tiny dust particles easily enter the cavity containing the springs and adhere to the spring coils or the guide surfaces of moving parts. Over time, the accumulation of dust can cause the elastic movement of the springs to become sluggish, preventing smooth compression and rebound, and making the axial thrust provided unstable or even ineffective. The direct consequence is that the necessary elastic compensation pressure is lost during fiber optic splicing, resulting in micro-gaps or insufficient contact force between the end faces, leading to a sharp increase in optical signal attenuation and unstable connections. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber optic connector housing for a smart sensor and a method for manufacturing the same, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fiber optic connector housing for a smart sensor, comprising: A mutually compatible connector and connector head, wherein optical fibers are connected to the connector and connector head; Multiple sets of guide grooves are provided on the inner wall of the connecting seat; A rotating assembly is rotatably mounted on the connecting seat, the rotating assembly is in contact with the inner wall of the connecting seat, and the rotating assembly is provided with a drive groove; A convex shaft is disposed on the outside of the connector. The convex shaft is adapted to the guide groove and the drive groove. When the convex shaft moves along the guide groove, it can cooperate with the drive groove to drive the rotating assembly to rotate. An energy storage component is disposed on the connecting seat and connected to the rotating assembly. The energy storage component has two states: energy storage and energy release. When the energy storage component is in the energy release state, it can drive the rotating assembly to rotate actively. A compression structure connects an energy storage component and an annular airbag disposed inside the connector. The compression structure is capable of delivering compressed gas to the annular airbag after the connector is locked to the connector head.

[0006] The fiber optic connector housing of the smart sensor as described above: the guide groove includes a limiting groove disposed on the inner wall of the connector seat and a first inclined surface disposed at the end of the limiting groove and connected to the side wall of the limiting groove, the limiting groove and the two sets of the first inclined surfaces forming a "Y" shaped structure; The first inclined surface can guide the convex shaft into the defined groove.

[0007] The fiber optic connector housing of the smart sensor as described above: the rotating assembly includes an inner ring rotatably sleeved on the inner wall of the connector seat and an outer ring disposed outside the connector seat, the outer ring passing through a through groove disposed on the connector seat and being coaxially and fixedly connected to the inner ring; The drive slot is disposed on the inner ring.

[0008] The fiber optic connector housing of the smart sensor as described above: the driving groove includes a first spiral groove and an arc groove disposed on the inner ring, the first spiral groove and the arc groove are connected, and a second inclined surface is disposed at the end of the first spiral groove away from the arc groove; The second inclined surface, the first spiral groove, and the arc groove form a "Y" shaped structure.

[0009] The fiber optic connector housing of the smart sensor as described above: the energy storage component includes multiple sets of cylindrical slots disposed on the connector seat and an extension shaft slidably installed in the cylindrical slots, the extension shaft being connected to the inner wall of the cylindrical slots by a cylindrical spring; The energy storage component also includes a fitting shaft rotatably mounted on the extension shaft and multiple sets of trigger slots disposed on the outer ring, wherein the fitting shaft is capable of rolling within the trigger slots.

[0010] The fiber optic connector housing of the smart sensor as described above: the trigger groove includes a second spiral groove and a third spiral groove disposed on the outer ring, the second spiral groove and the third spiral groove are connected, and a protrusion opposite to the connector is formed at the connection between the second spiral groove and the third spiral groove.

[0011] The fiber optic connector housing of the smart sensor as described above: the compression structure includes an external component fixedly installed on the outer wall of the connector, a cylindrical cavity is formed inside the external component, a sealing plug is slidably installed inside the cylindrical cavity, and the cylindrical cavity is connected to the annular airbag through a conduit; A connecting plate is connected to the extension shaft, and the connecting plate is fixedly connected to the sealing plug.

[0012] The fiber optic connector housing of the smart sensor as described above: the annular airbag is disposed in an annular groove formed in the connector seat, and one side of the annular airbag is connected to the side wall of the annular groove; The annular airbag has a curved section on the other side, and the annular airbag has a toothed section on its axial side. The toughness of the curved section is less than that of the toothed section.

[0013] A method for manufacturing an optical fiber connector housing for a smart sensor as described above includes the following steps: Step 1: Mix the metal powder and plastic binder, then granulate the mixture to obtain the feedstock; Step 2: Heat the feed material to a molten state and then inject it into the mold to obtain a green embryo; Step 3: Pass fuming nitric acid into the green preform and heat it to remove the plastic, obtaining a degreased preform; Step 4: Vacuum sinter the degreased blank and cool it to obtain the workpiece.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By using the compression components and annular airbags, firstly, the annular airbags can fill the gap between the connector and the connector seat when they expand, preventing external dust from entering the connector seat through the gap and affecting the stable connection of the optical fiber. Secondly, during the deformation of the annular airbags, there is a tendency to push the connector further into the connector seat, so that the ends of the two sets of optical fibers can generate a greater interaction force, thereby ensuring the connection strength of the optical fiber ends and improving the connection stability. By incorporating guide grooves, rotating assemblies, convex shafts, and energy storage components, a stable connection between the connector and the connector seat can be achieved, preventing accidental separation caused by external forces. Furthermore, after the connector and connector seat are fully inserted, the annular airbag can be inflated, thus preventing the annular airbag from creating resistance to the connector's entry and ensuring that the connector can be smoothly attracted into the connector seat. This also prevents wear on the annular airbag. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-11 As an embodiment of the present invention, the fiber optic connector housing of the smart sensor includes: a connector 1 and a connector head 2, multiple sets of guide grooves 5, a rotating assembly, a convex shaft 4, an energy storage component, and a compression structure.

[0029] The connector 1 and connector 2 are mutually compatible, and optical fibers 3 are connected to the connector 1 and connector 2. Multiple sets of the guide grooves 5 are disposed on the inner wall of the connecting seat 1. The guide groove 5 includes a limiting groove 501 disposed on the inner wall of the connecting seat 1 and a first inclined surface 502 disposed at the end of the limiting groove 501 and connected to the side wall of the limiting groove 501. The limiting groove 501 and the two sets of the first inclined surfaces 502 form a "Y" shaped structure. The first inclined surface 502 can guide the convex shaft 4 into the limiting groove 501.

[0030] In this embodiment, when the connector 2 is inserted into the connector 1, the end of the connector 2 will first be inserted into the connector 1. During subsequent insertion, the convex shaft 4 on the connector 2 will be locked at the outer end of the connector 1. At this time, by rotating the connector 2, the convex shaft 4 can be rotated relative to the connector 1. When the convex shaft 4 rotates between the two sets of first inclined surfaces 502, the first inclined surfaces 502 can guide the convex shaft 4 to slide into the limiting groove 501. At this time, with the cooperation of the limiting groove 501 and the convex shaft 4, the axial locking between the connector 1 and the connector 2 can be achieved, ensuring the relative stability between the two in the connected state, and preventing the two sets of optical fibers 3 from rotating relative to each other during the connection process, which would cause the fiber cores of the optical fibers 3 to be misaligned, resulting in signal attenuation or even interruption.

[0031] Among them, the two sets of first inclined surfaces 502 are distributed in a figure-eight shape and are connected to the side wall of the limiting groove 501 at the closing point. This makes it easier to put the convex shaft 4 into the limiting groove 501, which has a "foolproof" effect and reduces the difficulty in the process of connecting the connector 1 and the connector 2.

[0032] Please see Figures 4-5 , Figure 7 The rotating assembly is rotatably mounted on the connecting seat 1, the rotating assembly is in contact with the inner wall of the connecting seat 1, and the rotating assembly is provided with a drive groove. The rotating assembly includes an inner ring 6 rotatably sleeved on the inner wall of the connecting seat 1 and an outer ring 7 disposed outside the connecting seat 1. The outer ring 7 passes through a through groove 102 on the connecting seat 1 and is coaxially fixedly connected to the inner ring 6. This ensures that the inner ring 6 and the outer ring 7 can rotate synchronously, so that when the inner ring 6 rotates, it can drive the outer ring 7 to rotate, and when the outer ring 7 rotates, it can also synchronously drive the inner ring 6 to rotate.

[0033] The driving groove is disposed on the inner ring 6. The driving groove includes a first spiral groove 601 and an arc groove 602 disposed on the inner ring 6. The first spiral groove 601 communicates with the arc groove 602, and a second inclined surface 603 is disposed at the end of the first spiral groove 601 away from the arc groove 602. The second inclined surface 603, the first spiral groove 601, and the arc groove 602 form a "y" shaped structure.

[0034] The convex shaft 4 is disposed on the outside of the connector 2. The convex shaft 4 is adapted to the guide groove 5 and the drive groove. When the convex shaft 4 moves along the guide groove 5, it can cooperate with the drive groove to drive the rotating assembly to rotate.

[0035] In the initial state, the energy storage component keeps the inner ring 6 and outer ring 7 stationary. At this time, the first inclined surface 502 can overlap with the second inclined surface 603. In this state, the first inclined surface 502 can guide the convex shaft 4 into the limiting groove 501 and the first spiral groove 601. During the docking process between the connector 1 and the connector 2, the convex shaft 4 will always move towards the bottom of the connector 1. During this process, the convex shaft 4 will also cooperate with the first spiral groove 601 to drive the inner ring 6 and outer ring 7 to move, and make the energy storage component perform energy storage action in the energy storage state. When the connector 2 enters the connector 1 to a certain depth, the energy storage component will enter the energy release state. At this time, the energy storage component will drive the outer ring 7 and inner ring 6 to move. During this process, the first spiral groove 601 will actively rotate and cooperate with the convex shaft 4, pulling the connector 2 towards the connector 1, so that the connector 1 and the connector 2 have an automatic suction effect, improving the operation feel during insertion.

[0036] When the energy storage structure drives the outer ring 7 and the inner ring 6 to rotate to the end of their stroke, the convex shaft 4 will enter the arc-shaped groove 602. The length direction of the arc-shaped groove 602 is perpendicular to the axis of the connector 2. This allows the convex shaft 4 to act perpendicularly on the side wall of the arc-shaped groove 602 when an external force is applied to the connector 2 to separate it from the connector seat 1, without causing the inner ring 6 to generate a rotational force. This ensures the connection stability between the connector seat 1 and the connector 2 and prevents unexpected separation of the connector seat 1 and the connector 2 due to external force pulling.

[0037] Please see Figure 4 , Figure 7 , Figure 11 The energy storage component is disposed on the connecting seat 1 and connected to the rotating assembly. The energy storage component has two states: energy storage and energy release. When the energy storage component is in the energy release state, it can drive the rotating assembly to rotate actively. The energy storage component includes multiple sets of cylindrical grooves 103 disposed on the connecting seat 1 and an extension shaft 8 slidably installed in the cylindrical grooves 103. The extension shaft 8 is connected to the inner wall of the cylindrical grooves 103 by a cylindrical spring 9. The energy storage component also includes a fitting shaft 10 rotatably mounted on the extension shaft 8 and multiple sets of trigger grooves disposed on the outer ring 7, wherein the fitting shaft 10 is capable of rolling within the trigger grooves; The trigger groove includes a second spiral groove 701 and a third spiral groove 702 disposed on the outer ring 7. The second spiral groove 701 and the third spiral groove 702 are connected, and a protrusion opposite to the connector 2 is formed at the connection between the second spiral groove 701 and the third spiral groove 702. The lead of the second spiral groove 701 is smaller than the lead of the third spiral groove 702.

[0038] In this embodiment, the cylindrical spring 9 is initially stretched, and in this state, the fitting shaft 10 is located at the end of the second spiral groove 701 away from the third spiral groove 702. When the connector 2 is inserted into the connector seat 1, the convex shaft 4 cooperates with the first spiral groove 601 to rotate the inner ring 6 and the outer ring 7, so that the fitting shaft 10 can move along the length direction of the second spiral groove 701 toward the protrusion, allowing the cylindrical spring 9 to be further stretched and store elastic potential energy (this is the energy storage state). When the connector 2 is inserted into the connector seat 1 to a certain depth, the fitting shaft 10 will move past the protrusion, at which time the cylindrical spring 9 will release elastic potential energy (this is the energy release state). While pulling the extension shaft 8 toward the cylindrical groove 103, the fitting shaft 10 can move along the third spiral groove 702. During this process, the inner ring 6 and the outer ring 7 are in an active rotation state, thus achieving the effect of "sucking" the connector 2 into the connector seat 1.

[0039] Furthermore, when the convex shaft 4 moves to the end of the first spiral groove 601, the fitting shaft 10 has not yet moved to the end of the third spiral groove 702. At this time, the inner ring 6 and the outer ring 7 will continue to rotate, so that the convex shaft 4 can enter the arc groove 602, realize the locking between the connecting seat 1 and the connecting head 2, and ensure the connection stability between the two.

[0040] Please see Figures 1-4 , Figures 9-10 The compression structure connects the energy storage component and the annular airbag 15 disposed inside the connecting seat 1. The compression structure can deliver compressed gas to the annular airbag 15 after the connecting seat 1 and the connecting head 2 are locked. The compression structure includes an external component 12 fixedly installed on the outer wall of the connecting seat 1. A cylindrical cavity 1201 is formed inside the external component 12. A sealing plug 13 is slidably installed inside the cylindrical cavity 1201, and the cylindrical cavity 1201 is connected to the annular airbag 15 through a conduit 14. A connecting plate 11 is connected to the extension shaft 8, and the connecting plate 11 is fixedly connected to the sealing plug 13.

[0041] In this embodiment, the lead of the second spiral groove 701 is less than the lead of the third spiral groove 702, so that when the fitting shaft 10 moves along the second spiral groove 701 toward the protrusion, the extension shaft 8 is in a state of pulling the sealing plug 13 away from the connector 2. That is, at this time, the cylindrical cavity 1201 is in a negative pressure state, so that the annular airbag 15 is in a contracted state. In this way, during the process of the connector 2 being inserted into the connector seat 1, the annular airbag 15 is prevented from generating resistance to the entry of the connector 2, so that the connector 2 can be smoothly sucked into the connector seat 1.

[0042] When the inner ring 6 rotates to draw the connector 2 into the connector seat 1, the convex shaft 4 will also move along the arc groove 602. At this time, the fitting shaft 10 will still move along the third spiral groove 702, while the extension shaft 8 will reset and move in the opposite direction toward the cylindrical groove 103. At this time, the sealing plug 13 can compress the gas in the cylindrical cavity 1201, so that the gas can be compressed into the annular air bag 15, thereby expanding the annular air bag 15 to fill the gap between the connector 2 and the connector seat 1, preventing external dust from entering the interior of the connector seat 1 through the gap between the two and affecting the connection stability of the optical fiber 3.

[0043] It should be noted that the lead of the second spiral groove 701 being less than the lead of the third spiral groove 702 can be understood as follows: taking the plane passing through the central axis of the connector 2 as the reference plane, the projected length of the second spiral groove 701 along the length of the central axis of the inner ring 6 on this reference plane is less than the projected length of the third spiral groove 702 along the length of the central axis of the inner ring 6 on this reference plane. We take a point a on the third spiral groove 702, which is coplanar with the vertex of the end of the second spiral groove 701, and this plane is perpendicular to the central axis of the inner ring 6. In this way, when the fitting shaft 10 moves along the second spiral groove 701 to the protrusion, and is then moved by the protrusion... When the extension shaft 8 moves to point a of the third spiral groove 702, it actually performs a telescopic action. During the above process, the convex shaft 4 also moves to the end of the first spiral groove 601. This allows the convex shaft 4 to move along the arc groove 602 when the fitting shaft 10 moves from point a toward the end of the third spiral groove 702 and the inner ring 6 continues to rotate. The sealing plug 13 can press compressed gas into the annular airbag 15. That is, the annular airbag 15 will only expand after the connector 2 and the connector seat 1 are locked. This can prevent the annular airbag 15 from resisting the insertion of the connector 2 and prevent unnecessary wear on the annular airbag 15.

[0044] Please see Figure 6 , Figure 9 The annular airbag 15 is disposed in the annular groove 101 formed in the connecting seat 1, and one side of the annular airbag 15 is connected to the side wall of the annular groove 101. A curved portion 1501 is provided on the other side of the annular airbag 15, and a toothed portion 1502 is provided on the side of the annular airbag 15 along its axial direction. The toughness of the curved portion 1501 is less than that of the toothed portion 1502.

[0045] In this embodiment, when compressed gas is filled into the annular airbag 15, the bending portion 1501 will deform preferentially because its toughness is less than that of the inverted tooth portion 1502. This allows the annular airbag 15 to form a cross-section that resembles an isosceles trapezoid. At this time, the inverted tooth portion 1502 near the bending portion 1501 can fit against the connector 1 and the connector 2, thereby filling the gap between the connector 1 and the connector 2. As the gas continues to be injected, the inverted tooth portion 1502 will also deform, causing the annular airbag 15 to move away from the connector 2 along the length of the annular groove 101. At this time, the friction force can cause the connector 2 to continue to push towards the connector 1, thereby ensuring the stability of the connection of the optical fibers 3 inside the connector 1 and the connector 2.

[0046] When the reverse teeth 1502 deforms, multiple sets of reverse teeth 1502 will fit against the outside of the connector 2. At this time, multiple sets of coaxial sealing rings can be formed between the reverse teeth 1502 and the connector 2, which further improves the sealing effect.

[0047] Based on the above settings, firstly, the annular airbag 15 can fill the gap between the connector 2 and the connector 1 when it expands, preventing external dust from entering the connector 1 through the gap between the connector 1 and the connector 2 and affecting the stable connection of the optical fiber 3. Secondly, during the deformation of the annular airbag 15, it tends to push the connector 2 further into the connector 1, so that the ends of the two sets of optical fibers 3 can generate a greater interaction force, thereby ensuring the connection strength of the ends of the optical fibers 3 and improving the connection stability.

[0048] As an embodiment of the present invention, a method for manufacturing the fiber optic connector housing of the smart sensor as described above is also proposed, comprising the following steps: Step 1: Mix the metal powder and plastic binder, then granulate the mixture to obtain the feedstock; Step 2: Heat the feed material to a molten state and then inject it into the mold to obtain a green embryo; Step 3: Pass fuming nitric acid into the green preform and heat it to remove the plastic, obtaining a degreased preform; Step 4: Vacuum sinter the degreased blank and cool it to obtain the workpiece.

[0049] Furthermore, in step one, the metal powder and plastic binder are mixed and stirred evenly in a certain proportion to form a feed. The metal powder accounts for 91.5% by mass, and the plastic binder accounts for 8.5% by mass. In the plastic binder, polyoxymethylene accounts for 83%, polystyrene accounts for 8%, zinc stearate accounts for 5%, paraffin wax accounts for 1%, and antioxidant accounts for 3%.

[0050] In step two, the feed material is fed into the injection molding machine's hopper, heated to a molten state, and then injected into the mold to obtain the desired blank.

[0051] In step three, the blank is placed in a degreasing furnace and degreased with 98% pure fuming nitric acid to achieve a degreasing rate of 6.9%-7.6%.

[0052] In step four, the degreased blank is vacuum sintered. During sintering, hot degreasing is performed at 0℃-800℃, vacuum sintering is performed at 800℃-1050℃, partial pressure sintering is performed at 1050℃-1385℃, and the blank is held at 1385℃ for 2.5 hours before cooling. Argon gas is used for protection during the cooling stage. The workpiece is obtained after cooling is completed.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
