Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and in particular to an optoelectronic hybrid connector. Background Technology

[0002] Optoelectronic hybrid connectors are widely used in communication equipment, rail transportation, aerospace, and industrial automation to simultaneously transmit optical and electrical signals. Existing optoelectronic hybrid connectors typically consist of a male terminal assembly and a female terminal assembly. The male and female terminals are usually locked together using a threaded connection structure. This is achieved by the interlocking of the internal thread on the inner side of the coupling nut in the female terminal assembly with the external thread on the outer side of the male terminal assembly. The insertion and locking of the male and female terminals are gradually completed as the coupling nut is rotated.

[0003] However, during rotation, the internal and external threads continuously contact and generate friction, requiring continuous overcoming of the frictional resistance between the threaded pairs. This results in a more laborious connection operation and lower insertion efficiency, especially in applications requiring frequent insertion and removal, where the problems are more pronounced.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an optoelectronic hybrid connector that addresses the above-mentioned deficiencies of the prior art, and aims to solve the problem of low insertion efficiency caused by the threaded connection between the male and female components in the prior art.

[0006] The technical solution adopted by this invention to solve the technical problem is as follows: An optoelectronic hybrid connector, comprising: The female end assembly has several positioning posts on its inner wall. Male terminal assembly; the outer wall of the male terminal assembly is provided with a plurality of guide grooves; the guide grooves are slidably engaged with the positioning post to guide the male terminal assembly to rotate and insert relative to the female terminal assembly.

The guide section is connected at one end to the inlet section and at the other end in a direction away from the female end assembly, and extends along the circumference and axial direction of the male end assembly.

[0008] The aforementioned optoelectronic hybrid connector further includes: A female end alignment mark is provided on the outer wall of the female end assembly; A male end alignment mark is provided on the outer wall of the male end assembly; when the male end alignment mark corresponds to the female end alignment mark, the positioning post corresponds to the opening.

[0009] The aforementioned optoelectronic hybrid connector further includes: The locking mechanism is partially disposed on the female end assembly and partially disposed on the male end assembly, so as to provide detachable locking when the female end assembly and the male end assembly are plugged in and engaged.

[0010] The optoelectronic hybrid connector, wherein the locking mechanism includes a limiting rib and a rotating wrench; the limiting rib is disposed on the outer wall of one of the female end assembly and the male end assembly, and the rotating wrench is hinged to the outer wall of the other; the rotating wrench is provided with a hook; when the female end assembly and the male end assembly are inserted and engaged, the limiting rib is located on the rotation path of the hook and is detachably engaged with the hook.

[0011] The aforementioned optoelectronic hybrid connector, wherein the rotary wrench comprises: Arc segment; the hooks are disposed at both ends of the arc segment; the end of the hook near the arc segment is hinged to the male end assembly or the female end assembly, and the end of the hook away from the arc segment is provided with a receiving position, which is used to receive the limiting rib; The handle is connected to the arc segment.

[0012] The aforementioned optoelectronic hybrid connector, wherein the locking mechanism further includes: The positioning component is partially disposed on the rotary wrench and partially disposed on the female end component to position the hook in a state of engagement with the limiting rib.

[0013] The aforementioned optoelectronic hybrid connector, wherein the positioning component includes: A positioning sleeve is fitted onto the female end assembly and can move along the axial direction of the female end assembly; An extension portion; one end of the extension portion is connected to the arc segment, and the other end is a free end; there is a receiving position between the positioning sleeve and the female end assembly, the receiving position is used to receive the free end of the extension portion; when the hook engages with the limiting rib, the free end of the extension portion is located on the moving path of the receiving position along the axial direction of the female end assembly.

[0014] The aforementioned optoelectronic hybrid connector further includes: At least one protective positioning pin is disposed around the fiber optic terminal of the male terminal assembly; the end face of the protective positioning pin extends beyond the end face of the fiber optic terminal of the male terminal assembly. A positioning hole is provided on the female end assembly; when the female end assembly and the male end assembly are inserted and engaged, the positioning hole is engaged with the protective positioning pin.

[0015] Beneficial effects: This application uses a sliding fit between the positioning pin and the guide groove to replace the continuous meshing of internal and external threads.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the units related to the present invention and are not drawn according to the actual number, shape and size of the units. In actual implementation, the form, quantity and proportion of each unit can be arbitrarily changed, and the unit layout may also be more complex.

[0019] This application provides an optoelectronic hybrid connector, such as... Figure 1 As shown, the optoelectronic hybrid connector includes a female terminal assembly 100 and a male terminal assembly 200; as Figure 4 As shown, a plurality of positioning posts 300 are provided on the inner wall of the female end assembly 100; as Figure 2 As shown, the outer wall of the male end component 200 is provided with a plurality of guide grooves 400; the guide grooves 400 slide with the positioning post 300 to guide the male end component 200 to rotate and insert relative to the female end component 100.

[0020] Specifically, the female end assembly 100 includes a coupling nut, and a positioning post 300 is disposed on the inner wall of the coupling nut; the outer wall of the male end assembly 200 is provided with guide grooves 400 that correspond one-to-one with the positioning posts 300. During assembly, the positioning posts 300 enter the corresponding guide grooves 400. When the operator rotates the coupling nut, the positioning posts 300 slide along the guide grooves 400, and under the guidance of the side wall of the guide grooves 400, guide the male end assembly 200 to perform a rotational insertion engagement with the female end assembly 100. As the positioning posts 300 continue to move along the guide grooves 400, the male end assembly 200 gradually completes the insertion and connection with the female end assembly 100, without relying on the continuous meshing of traditional internal and external threads to achieve axial advancement.

[0021] Compared to traditional threaded connections, this application uses a sliding fit between a positioning pin 300 and a guide groove 400 instead of continuous engagement of internal and external threads. The positioning pin 300 only forms partial contact within the guide groove 400 and moves along the guide groove 400, reducing the contact area of ​​continuous engagement during the connection process and lowering the frictional resistance during rotation. Simultaneously, the guide trajectory of the guide groove 400 can be pre-designed according to the insertion stroke of the male end assembly 200 and the female end assembly 100, allowing the positioning pin 300 to complete the entire insertion process simply by moving along the guide groove 400 to a predetermined position. Unlike traditional threaded connections, it does not require multiple turns of rotation for locking, effectively reducing the rotation angle and operation steps, improving insertion efficiency, and lowering the force required by the operator.

[0022] It should be noted that when multiple positioning posts 300 are designed, these posts are spaced apart circumferentially along the coupling nut and respectively engage with multiple guide grooves 400. This allows the male terminal assembly 200 to bear force from multiple positions during insertion, resulting in a more uniform axial thrust distribution. This effectively reduces the possibility of tilting, offsetting, or jamming of the male terminal assembly 200 during insertion, improving the guiding accuracy and insertion stability of the male terminal assembly 200 and the female terminal assembly 100. For optoelectronic hybrid connectors, a stable and smooth insertion process also helps ensure accurate alignment of the fiber optic terminals and electrical connection terminals, reducing the risk of decreased connection reliability or terminal damage due to insertion misalignment, thereby further improving the connection reliability and service life of the optoelectronic hybrid connector.

[0023] In one embodiment of this application, there are three positioning posts 300, which are evenly distributed along the circumference of the coupling nut and respectively engage with three guide grooves 400. During the insertion process, the three positioning posts 300 can guide the male end assembly 200 from three different circumferential positions, so that the male end assembly 200 is uniformly constrained during axial advancement, reducing the possibility of tilting, shaking or offset of the male end assembly 200, thereby improving the stability of the insertion process.

[0024] Meanwhile, the three positioning posts 300 form a stable three-point guiding structure, allowing the male end component 200 to be guided and constrained simultaneously from multiple circumferential positions during insertion. This reduces the possibility of tilting, offsetting, or jamming of the male end component 200, improving the coaxiality and insertion stability between the male end component 200 and the female end component 100. Furthermore, the three positioning posts 300 share the rotational torque and axial propulsion force, reducing the stress and wear on individual positioning posts 300 and guide grooves 400, thus extending the service life of the connection structure. In addition, compared to the over-constrained structure formed by four or more positioning posts 300, three positioning posts 300 are more adaptable to machining and assembly errors, reducing insertion resistance while ensuring guiding accuracy, and facilitating faster and more labor-saving insertion connections.

[0025] One embodiment of this application, such as Figure 2 As shown, the guide groove 400 includes an inlet section 401 and a guide section 402; the inlet section 401 has an opening; the opening is located on the axial end face of the male end assembly 200 near the female end assembly 100; one end of the guide section 402 is connected to the inlet section 401, and the other end of the guide section 402 extends away from the female end assembly 100 and is arranged along the circumference and axial direction of the male end assembly 200.

[0026] When the male end assembly 200 and the female end assembly 100 begin to assemble, the positioning pin 300 first enters the inlet section 401 through the opening. Since the opening is located on the axial end face of the male end assembly 200, the operator only needs to insert the male end assembly 200 axially into the female end assembly 100 to allow the positioning pin 300 to quickly enter the guide groove 400. There is no need to repeatedly adjust the relative position between the positioning pin 300 and the guide groove 400, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0027] After the positioning pin 300 enters the inlet section 401, it further enters the guide section 402 and slides along it. The guide section 402 constrains and guides the movement trajectory of the positioning pin 300, guiding the male end assembly 200 to engage with the female end assembly 100 during its movement within the guide section 402, thereby achieving the connection between the male end assembly 200 and the female end assembly 100. The guide section 402 extends both circumferentially and axially along the male end assembly 200. When the positioning pin 300 slides along the guide section 402, the guide section 402 converts the rotational motion of the coupling nut into the axial feed motion of the male end assembly 200 relative to the female end assembly 100, allowing the male end assembly 200 to complete the engagement within a smaller rotation angle, reducing the number of rotations required during the connection process, improving engagement efficiency, and simultaneously reducing operating resistance. With the cooperation of the inlet section 401 and the guide section 402, the positioning post 300 can gradually transition from axial insertion to guiding movement, which not only makes the entire insertion process smoother, but also reduces the possibility of collision or jamming between the positioning post 300 and the entrance of the guide groove 400, thus improving the reliability of insertion.

[0028] In one embodiment of this invention, the guide section 401 extends axially along the male end assembly 200. During the initial insertion of the male end assembly 200, the positioning post 300 and the guide groove 400 primarily engage in axial guiding contact, preventing the positioning post 300 from directly colliding with the sidewall of the guide section 402, reducing insertion resistance and localized wear, and improving the smoothness of the insertion process. After the positioning post 300 enters the guide section 401, it then enters the guide section 402, which communicates with the guide section 401. The guide section 402 guides the positioning post 300 to move along a predetermined trajectory, thereby achieving the insertion contact between the male end assembly 200 and the female end assembly 100. This ensures a smooth transition from axial guidance to guiding movement during the insertion process, improving the reliability and stability of the connection.

[0029] In other embodiments, the guide section 401 may be inclined relative to the axis, or the guide section 401 may extend at least partially in an arc shape, as long as the positioning post 300 can smoothly enter the guide groove 400.

[0030] In one embodiment of this application, the optoelectronic hybrid connector further includes a female end alignment mark 500 and a male end alignment mark 600; as shown Figure 3 As shown, the female end alignment mark 500 is provided on the outer wall of the female end assembly 100; as Figure 2 As shown, the male end alignment mark 600 is provided on the outer wall of the male end assembly 200; when the male end alignment mark 600 corresponds to the female end alignment mark 500, the positioning post 300 corresponds to the opening.

[0031] Specifically, when the male end alignment mark 600 corresponds to the female end alignment mark 500, the positioning post 300 and the opening of the guide groove 400 are synchronously aligned. At this time, the operator does not need to observe the internal structure of the connector. He only needs to make the two alignment marks correspond so that the positioning post 300 can be accurately aligned with the opening of the guide groove 400, thereby completing the initial alignment before insertion. In this process, the operator does not need to repeatedly rotate the male end assembly 200 to find the entrance of the guide groove 400, which reduces the collision between the positioning post 300 and the end face of the female end assembly 100 and the repeated trial insertion, reduces the difficulty of insertion operation, and improves insertion efficiency.

[0032] Meanwhile, the alignment mark is set on the outer wall of the connector, allowing the operator to complete the alignment directly by visual inspection. Even when the internal structure of the connector is not visible, the correct insertion posture can be quickly determined, which helps to shorten the assembly time and improve the consistency and reliability of the connection.

[0033] Therefore, the male end alignment mark 600 and the female end alignment mark 500 form an external visual alignment reference, while the positioning post 300 and the guide groove 400 opening form an internal mechanical guiding reference. The external visual alignment and the internal mechanical guidance work together to allow the operator to complete accurate assembly without having to repeatedly adjust the insertion angle based on experience. This not only improves connection efficiency but also reduces the risk of collision, wear, or even impact on subsequent connections caused by incorrect insertion position of the positioning post 300 and the guide groove 400, further improving the reliability of the optoelectronic hybrid connector.

[0034] In one embodiment of this example, both the male end alignment mark 600 and the female end alignment mark 500 are equilateral triangle alignment marks, and when the positioning post 300 corresponds to the opening, the apex of the male end alignment mark 600 corresponds to the apex of the female end alignment mark 500.

[0035] In one embodiment of this application, the optoelectronic hybrid connector further includes a locking mechanism, which is partially disposed on the female end assembly 100 and partially disposed on the male end assembly 200, so as to perform detachable locking when the female end assembly 100 and the male end assembly 200 are plugged in.

[0036] Specifically, the locking mechanism has two states: locked and unlocked. After the male terminal component 200 is inserted into the female terminal component 100 through the cooperation of the positioning post 300 and the guide groove 400, the operator adjusts the locking mechanism to the locked state, forming a detachable connection between the male terminal component 200 and the female terminal component 100. This axially limits the insertion of the male terminal component 200 and the female terminal component 100, preventing them from separating under external tension. Simultaneously, the locking mechanism also restricts unintended relative rotation between the male terminal component 200 and the female terminal component 100, preventing the positioning post 300 in the guide groove 400 from moving in the opposite direction and causing the connection to loosen, thereby improving the connection stability and reliability of the connector.

[0037] In one embodiment of this invention, the locking mechanism includes a limiting rib 700 and a rotary wrench 800; the limiting rib 700 is disposed on the outer wall of one of the female end assembly 100 and the male end assembly 200, and the rotary wrench 800 is hinged to the outer wall of the other; as shown... Figure 1 and Figure 3 As shown, the rotary wrench 800 is equipped with a latch 801; as Figure 1 As shown, when the female end assembly 100 and the male end assembly 200 are plugged in, the limiting rib 700 is located on the rotation path of the hook 801 and is detachably engaged with the hook 801.

[0038] Specifically, the rotary wrench 800 is hinged to the male end assembly 200 or the female end assembly 100 via the hinge shaft 3000. When the female end assembly 100 and the male end assembly 200 are engaged, the limiting protrusion 700 enters the rotation path range of the latch 801. At this time, when the rotary wrench 800 is rotated, the latch 801 rotates synchronously with the rotary wrench 800 and engages with the limiting protrusion 700, so that the limiting protrusion 700 is restricted within the latch 801, thereby restricting relative movement between the female end assembly 100 and the male end assembly 200 and realizing the locking connection between the two.

[0039] It is understandable that, in the initial state, such as Figure 6As shown, with the rotary wrench 800 in the released state, the latch 801 does not obstruct the relative insertion and connection movement of the female end assembly 100 and the male end assembly 200. When the male end assembly 200 and the female end assembly 100 move to the predetermined connection position via the guide post and guide groove 400, the position of the limiting rib 700 corresponds to that of the latch 801. At this time, the operator rotates the rotary wrench 800, causing the latch 801 to rotate around the hinge shaft 3000 and engage with the limiting rib 700. The mechanical constraint between the latch 801 and the limiting rib 700 keeps the female end assembly 100 and the male end assembly 200 in a connected state. When disassembly is required, simply rotate the rotary wrench 800 in the opposite direction to disengage the latch 801 from the limiting rib 700, thus releasing the lock and enabling quick assembly and disassembly.

[0040] Since the coupling nut is part of the female end assembly 100, it needs to be rotated to achieve relative movement between the guide post and the guide groove 400. In traditional structures, the operator usually needs to directly hold the outer circumferential surface of the coupling nut to rotate it. Due to the limited radial dimension of the coupling nut, the lever arm when the operator applies force is short, resulting in a large operating force.

[0041] Based on this, in one embodiment of this invention, a rotary wrench 800 is disposed on the female end assembly 100 and hinged to the coupling nut. A limiting rib 700 is disposed on the male end assembly 200. The operator can directly grasp the rotary wrench 800, which extends outward from the coupling nut, for rotational operation. Since the rotary wrench 800 effectively increases the force application radius, the force applied by the operator generates a larger torque relative to the rotation center of the coupling nut. Under the same operating force conditions, a larger rotational driving torque can be generated, thereby reducing the operating force required to rotate the coupling nut and making the insertion process between the male end assembly 200 and the female end assembly 100 more effortless.

[0042] The rotary wrench 800 includes an arc segment 802 and a handle 803; hooks 801 are disposed at both ends of the arc segment 802; the end of the hook 801 near the arc segment 802 is hinged to the male end assembly 200 or the female end assembly 100, and the end of the hook 801 away from the arc segment 802 is provided with a receiving position 8011, which is used to receive the limiting rib 700; the handle 803 is connected to the arc segment 802.

[0043] Specifically, there are two hooks 801, which are radially distributed at both ends of the arc segment 802 along the female end assembly 100, so that one arc segment 802 can simultaneously connect to two hooks 801. The connection between the hook 801 and the arc segment 802 is an arc transition and forms an obtuse angle, so that the hook 801 is inclined and extended relative to the arc segment 802. Since the end of the hook 801 away from the arc segment 802 is provided with a receiving position 8011 for receiving the limiting rib 700, the hook 801 needs to move to the corresponding position of the limiting rib 700 and engage with the limiting rib 700 during the rotation of the rotary wrench 800. By setting the angle between the arc segment 802 and the hook 801 to an obtuse angle, a smooth transition is formed between the hook 801 and the arc segment 802. This facilitates the adjustment of the spatial position of the hook 801 relative to the rotation center, allowing the receiving position 8011 at the far end of the hook 801 to enter the area where the limiting rib 700 is located more accurately, thereby improving the reliability of the fit between the limiting rib 700 and the receiving position 8011.

[0044] Furthermore, the obtuse-angle connection structure between the arc segment 802 and the hook 801 allows the end of the hook 801 furthest from the arc segment 802 to maintain a certain amount of outward extension space, giving the receiving position 8011 better clearance capability. After the male end assembly 200 and the female end assembly 100 are inserted, the limiting rib 700 can smoothly enter the receiving position 8011 without the need for the rotating wrench 800 to produce large elastic deformation, thereby reducing the resistance of the locking operation and improving the smoothness of the locking process.

[0045] In one embodiment of this invention, the receiving position 8011 and the limiting rib 700 are tightly fitted together. The receiving position 8011 mechanically limits the limiting rib 700, so that both the engagement and disengagement processes of the hook 801 and the limiting rib 700 require the operator to apply a certain external force to the rotary wrench 800. Specifically, during the locking process, the operator rotates the rotary wrench 800 to move the hook 801 to the corresponding position of the limiting rib 700, causing the limiting rib 700 to enter the receiving position 8011. When unlocking, the rotary wrench 800 needs to be rotated in the opposite direction to allow the hook 801 to overcome the resistance between itself and the limiting rib 700 and disengage from the limiting rib 700. Therefore, under normal use, a small external force is unlikely to drive the hook 801 to move relative to the limiting rib 700.

[0046] For example, when the connector is subjected to external disturbances such as bumps and vibrations during transportation or use, since such external forces are usually less than the operating force required to rotate the rotary wrench 800 and disengage the hook 801 from the limiting rib 700, the hook 801 cannot automatically disengage from the limiting rib 700. This can effectively prevent the male terminal component 200 from accidentally becoming loose from the female terminal component 100, and improve the connection stability and reliability of the optoelectronic hybrid connector in complex environments.

[0047] The locking mechanism in this application also includes a positioning component 900, which is partially disposed on the rotary wrench 800 and partially disposed on the female end component 100, to position the latch 801 in a state of engagement with the limiting protrusion 700. The positioning component 900 limits the rotational position of the rotary wrench 800, preventing the rotary wrench 800 from rotating in the reverse direction when not in operation, thereby improving the stability of the locking state.

[0048] Specifically, since the first layer of mechanical locking is formed between the latch 801 and the limiting rib 700, and the positioning component 900 provides a second layer of retention for the locked position of the rotary wrench 800, the locking mechanism forms a double anti-loosening structure. The latch 801 and the limiting rib 700 primarily bear the axial separation force on the connector, while the positioning component 900 primarily restricts the rotational movement of the rotary wrench 800. This ensures that unlocking requires active application of release force by the operator, thereby reducing the risk of locking failure due to environmental vibration or accidental collisions and improving the connector's vibration resistance and connection reliability.

[0049] The positioning component 900 includes a positioning sleeve 902 and an extension 901. The positioning sleeve 902 is sleeved on the female end component 100 and can move along the axial direction of the female end component 100. One end of the extension 901 is connected to the arc segment 802, and the other end of the extension 901 is a free end. There is a receiving position between the positioning sleeve 902 and the female end component 100, which is used to receive the free end of the extension 901. When the hook 801 is engaged with the limiting rib 700, the free end of the extension 901 is located on the moving path of the receiving position along the axial direction of the female end component 100.

[0050] Specifically, during the insertion of the male component 200 and the female component 100, the positioning sleeve 902 moves away from the rotary wrench 800, the rotary wrench 800 is in a released state, and the free end of the extension 901 is in a clearance state with the positioning sleeve 902. The rotary wrench 800 can rotate freely to facilitate the insertion and engagement of the male component 200 and the female component 100. After the male component 200 is inserted into the predetermined position, the operator rotates the rotary wrench 800, causing the rotary wrench 800 to drive the latch 801 to move and engage with the limiting rib 700 provided on another component. At this time, as the rotary wrench 800 rotates to the locked position, the free end of the extension 901 moves to the target position close to the female component 100 and can no longer move; then the positioning sleeve 902 moves towards the rotary wrench 800 until the free end of the extension 901 is inserted into the receiving position, thus completing the assembly of the positioning component 900.

[0051] By setting the aforementioned positioning component 900, the locking mechanism not only achieves the first-level locking through the engagement between the hook 801 and the limiting rib 700, but also further restricts the rotational position of the rotary wrench 800 through the cooperation between the positioning sleeve 902 and the extension 901, forming a secondary anti-loosening structure. Specifically, the hook 801 and the limiting rib 700 are mainly used to restrict the axial separation movement between the male end component 200 and the female end component 100, while the positioning sleeve 902 and the extension 901 are mainly used to restrict the rotary wrench 800 from rotating in the opposite direction, preventing the rotary wrench 800 from rotating due to external vibration, impact, or cable pulling, thus avoiding accidental disengagement of the hook 801 from the limiting rib 700.

[0052] In one embodiment of this invention, the positioning sleeve 902 and the female end assembly 100 are connected by a thread, so that the positioning sleeve 902 can reciprocate along the axial direction on the female end assembly 100.

[0053] In one embodiment of this invention, the extension 901 includes a bent section 9011 and a straight section 9012. The bent section 9011 is located near the handle 803; the straight section 9012 is located away from the handle 803 and is used for insertion into the receiving position. The bent section 9011 has an arc-shaped structure and connects the handle 803 and the straight section 9012, so that the extension 901 as a whole forms a curved transition structure. Since the rotary wrench 800 needs to rotate around the hinge position during the locking process, by providing the arc-shaped bent section 9011, the extension direction of the straight section 9012 relative to the handle 803 can be changed, so that the straight section 9012 can be adjusted to be consistent with the axial direction of the female end assembly 100 after the rotary wrench 800 rotates to the locking position.

[0054] Compared to the extension structure that uses a straight extension, this embodiment provides an arc-shaped bend 9011 between the handle 803 and the straight segment 9012, so that the extension 901 can adapt to the directional difference between the rotation trajectory of the rotary wrench 800 and the axial movement trajectory of the positioning sleeve 902. This avoids the straight segment 9012 becoming tilted after rotating with the rotary wrench 800, making it difficult to insert into the positioning sleeve 902, thereby improving the smoothness of the positioning component 900's fit.

[0055] In one embodiment of this application, the optoelectronic hybrid connector further includes at least one protective positioning pin 1000 (e.g., ...). Figure 5 (As shown) and positioning hole 2000; protective positioning pin 1000 is disposed around the fiber optic terminal of male terminal assembly 200; the end face of protective positioning pin 1000 extends beyond the end face of fiber optic terminal of male terminal assembly 200; as shown Figure 4 As shown, the positioning hole 2000 is provided on the female end assembly 100; when the female end assembly 100 and the male end assembly 200 are inserted and engaged, the positioning hole 2000 is inserted and engaged with the protective positioning pin 1000.

[0056] Because the protective positioning pin 1000 is located on the periphery of the fiber optic terminal and its end face is higher than that of the fiber optic terminal, it prioritizes alignment during the initial insertion stage, preventing the fiber optic terminal from directly contacting the female terminal assembly 100 before accurate alignment. When there is a deviation in the insertion angle or circumferential position of the male terminal assembly 200, the protective positioning pin 1000 cannot match the corresponding positioning hole 2000. The protective positioning pin 1000 will be blocked by the surrounding structure of the positioning hole 2000, allowing the operator to promptly detect insertion errors and preventing the fiber optic terminal from continuing to move forward and colliding with the female terminal assembly 100, thereby reducing the risk of damage to the fiber optic terminal.

[0057] When the male terminal assembly 200 and the female terminal assembly 100 are correctly aligned, the protective positioning pin 1000 can accurately enter the positioning hole 2000 and further limit the male terminal assembly 200 during the insertion process, ensuring that the fiber optic terminals maintain the correct relative position throughout the insertion process. Because a mechanical guiding relationship is formed between the positioning hole 2000 and the protective positioning pin 1000, the coaxiality and alignment accuracy between the fiber optic terminals are improved, ensuring accurate connection of the optical signal transmission path and enhancing the reliability of the connector connection.

[0058] In one embodiment of this invention, there are two protective positioning pins 1000 and two positioning holes 2000. The two protective positioning pins 1000 are distributed along the radial direction of the male terminal assembly 200 and are respectively disposed on the periphery of the fiber optic terminal. The two protective positioning pins 1000 correspond to the positioning holes 2000 disposed on the female terminal assembly 100. During the insertion process of the male terminal assembly 200 and the female terminal assembly 100, the two protective positioning pins 1000 are simultaneously inserted into the corresponding positioning holes 2000 to limit and correct the position of the male terminal assembly 200 relative to the female terminal assembly 100.

[0059] Meanwhile, the two radially distributed protective positioning pins 1000 can form a two-point positioning relationship. Because there is a certain distance between the two positioning points, the deflection movement of the male terminal assembly 200 during the insertion process can be effectively limited, preventing the male terminal assembly 200 from swinging around only a single positioning point, thereby improving the alignment accuracy between the male terminal assembly 200 and the female terminal assembly 100. At the same time, the two protective positioning pins 1000 are located on the periphery of the fiber optic terminal, providing protection and guidance to the fiber optic terminal from different directions, reducing the possibility of collision between the fiber optic terminal and the female terminal assembly 100 due to insertion angle deviation.

[0060] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
