[0005] The present invention relates to the technical field of optical communications, and in particular to a photoelectric hybrid connector. Background Art

[0006] Fiber optic communication uses light waves as the information carrier and optical fiber as the transmission medium. The field of optical communication typically involves components such as connectors, optical modules, and adapters.

[0007] Among them, connectors are optical passive devices that realize the connection between optical fibers. They have the functions of connecting optical fibers to optical fibers, optical fibers to active devices, optical fibers to equipment, optical fibers to other passive devices, and optical fibers to instruments. Optical modules are very important optical signal interface devices in optical fiber communications. They have optical interfaces and electrical interfaces. The optical interfaces connect to optical fibers to transmit optical signals, and the electrical interfaces connect to external communication terminal equipment. Adapters are used to transfer two connectors. Especially in optical fiber equipment represented by 5G base stations and FTTR equipment, there are a large number of plug-in optoelectronic lines in scenarios where wide-bandwidth communication and remote power supply are required. Since optoelectronics are set separately, there are many connectors and they are divided into two categories, optoelectronics and optical. They need to be correctly paired one by one, which makes the installation and maintenance process cumbersome and prone to plug-in errors.

[0008] On the other hand, in FTTH networks, traditional copper wires transmit network signals and also provide power to terminal terminals. However, as FTTH optical networks evolve towards FTTR optical networks, for example, in-vehicle terminals need to meet the demands of autonomous driving and artificial intelligence interaction. The bandwidth requirements of terminal terminals are increasing, and the signal transmission capacity of traditional copper wires can no longer meet these requirements. FTTR networks are shifting from copper to optical fiber at the terminal end, with power provided by cables. This is becoming a trend. To connect these composite cables, one existing solution is to design optical and electrical connectors separately. The optical connectors plug and couple with optical adapters to achieve optical signal connection, while the electrical connectors plug and couple with electrical adapters to achieve electrical signal connection. However, using separate optical and electrical connectors requires two plug-in / unplugging operations to complete the connection with the adapter. A solution is to use optoelectronic hybrid connectors and optoelectronic hybrid adapters. However, in some existing solutions, the electrical terminals of the connectors are partially exposed, posing a risk of electric shock and safety concerns during actual use.

[0009] On the other hand, the precision of the optical fibers of the fiber optic connector during the docking process is very high, basically requiring micron-level coupling. During the coupling and docking process, any force in the non-optical axis direction will affect the fiber optic coupling efficiency and fiber optic coupling accuracy; and the electrical terminals of the current optoelectronic hybrid connectors and optoelectronic hybrid adapters are asymmetric in the distribution of the optical fiber coupling structure, resulting in the plugging and unplugging stress of the electrical terminals during the plugging and unplugging process affecting the coupling accuracy of the optical channel of the fiber optic connector.

[0010] Another aspect is that in the process of technological transition, technological achievements are often not achieved all at once. Old technologies often coexist with new technologies for a long time before they are completely replaced by new technologies. Therefore, how to achieve pure optical docking connectors, pure electric docking connectors and optoelectronic hybrid connectors that are compatible and matched with each other is also a major technical problem that the industry needs to solve.

[0011] The above problems are particularly prominent in terminal scenarios with remote power supply 5G signal coverage and in-vehicle application scenarios with strict requirements for waterproof, dustproof and shockproof; in view of this, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field.

[0012] Application Contents

[0013] The technical problem to be solved by the present invention is to find a photoelectric hybrid connector that is suitable for a vehicle-like environment, can achieve a good shockproof effect, avoid the problem of connector connection state stability caused by vibrating objects in the environment, and is compatible.

[0014] The technical problem also solved by the present invention is to provide a photoelectric hybrid connector based on the shockproof photoelectric hybrid connector, which can effectively adapt to the application requirements of integrated and miniaturized hybrid connectors.

[0015] The present invention adopts the following technical solutions:

[0016] In a first aspect, the present invention provides a vibration-proof optoelectronic hybrid connector based on an environment with vibration.

[0017] A shockproof optoelectronic hybrid connector includes a male connector 1 and a female connector 2. Each of the male connector 1 and the female connector 2 is provided with a first ceramic abutment 11 and a second ceramic abutment 21 containing an optical fiber, as well as a first metal contact 12 arranged on at least one side of the first ceramic abutment 11 and a second metal contact 22 arranged on at least one side of the second ceramic abutment 21. The interlocking structure between the male connector 1 and the female connector 2 includes:

[0018] A first notch 23 having a first preset length is provided axially on the upper surface of the housing of the female connector 2, near the connecting end of the female connector 2 and the male connector 1. A first locking head 24 is provided on the first notch 23. A crossbar with a first locking head 14 and a pressing portion 15 is connected to the upper surface of the housing of the male connector 1 via a support rod 13. The first locking head 14 and the pressing portion 15 are located on opposite sides of the support rod 13.

[0019] After the female end connector 2 is connected to the male end connector 1, the first locking head 24 and the first locking port 14 are locked, and the first notch 23 accommodates part of the cross bar located above the male end connector 1; wherein, an anti-touch guardrail structure 16 with a height greater than or equal to the pressing portion in the locked state is provided in the cross bar accommodating area of ​​the male end connector 1.

[0020] In a second aspect, the present invention provides an optoelectronic hybrid connector based on the application demand for an integrated and miniaturized hybrid connector.

[0021] An optoelectronic hybrid connector, comprising a male connector 4 and a female connector 5, including:

[0022] The male connector 4 is composed of a first outer shell 41, a first ferrule assembly 42, a central axis assembly 43, and a first tail sleeve 44, which are interconnected. A rectangular boss 431 is formed on at least one horizontal surface of the central axis assembly 43. The rectangular boss 431 is used to limit the notch 451 of the door-type electrical terminal 45 and provide support for the door posts 452 on both sides. The door posts 452 of the door-type electrical terminal 45 extend beyond the end surface of the central axis assembly 43 and, after the first outer shell 41 and central axis assembly 43 are assembled, fit into the accommodating cavity 412 in the first outer shell 41. The accommodating cavity 412 is strip-shaped and is formed near the inner wall of the long side of the first outer shell 41, which is parallel to the axial direction.

[0023] The female connector 5 is composed of a second outer shell 51, a second ferrule assembly 52, a power transmission assembly 53, and a second tail sleeve 54, which are interconnected. The power transmission assembly 53 includes a cylindrical body 531 that interfaces with the second ferrule assembly 52, and a positioning member 532 fixed to the cylindrical body 531. The positioning member 532 is used to engage with a fork-shaped electrical terminal 533. The fork of the fork-shaped electrical terminal 533 is fixed after passing through a guide hole 511 on the inner wall of the second outer shell 51.

[0024] When the male connector 4 and the female connector 5 are connected, the first ferrule assembly 42 is docked with the second ferrule assembly 52, and the contacts on both sides of the fork head of the fork-shaped electrical terminal 533 are respectively in contact with the two side posts 452 of the door-shaped electrical terminal 45.

[0025] Compared with the prior art, the beneficial effect of the present invention is that the present invention realizes an optoelectronic hybrid connector suitable for vibration environments in similar vehicle-mounted scenarios by providing a set of first lock heads and first lock ports suitable for locking and unlocking between the male connector and the female connector, and their associated supporting structures.

[0026] In the preferred implementation scheme of the present invention, a set of effective waterproof structures is provided for waterproof and dustproof considerations, and the waterproof structure can interact with the above-mentioned locking structure in a structural manner, thereby greatly improving the installation and waterproof effects.

[0027] On the other hand, the present invention proposes a set of optoelectronic hybrid connectors, which cleverly integrate the electrical connection structure into the traditional pure optoelectronic electrolyzer. Moreover, during the implementation process, there is no need to increase the volume of the optical interface. The original structure's own characteristics are fully reused, and the position for the layout of the electrical connection structure is extracted from it. It can not only ensure that there will be no leakage problems, but also ensure that the strength of the connector itself will not be reduced after the integration of optoelectronics.

[0028] The electrical connection structure designed in the present invention also has its own strength, and in the preferred implementation scheme, the damping and convenience during the corresponding assembly process are also optimized. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Embodiment 1:

[0068] Embodiment 1 of the present invention provides a shockproof optoelectronic hybrid connector, as shown in Figures 1 and 2. Figure 1 is a cross-sectional view of Figure 2 after the ceramic ferrules contained therein are aligned along the axis, with the center axis cut along the A-A' line shown in Figure 2. Unless otherwise specified, the subsequent cross-sectional views in the embodiments of the present invention are cross-sectional views obtained by vertically cutting along the center axis of the ceramic ferrule. It should be noted that the scope of protection of the embodiments of the present invention is based on the textual description of the specification, and the corresponding drawings are example structures presented as relatively complete solutions. Therefore, the drawings in the specification are based on the effects presented in the complete textual description, so the contents of the drawings should not be overly interpreted to limit the complete structural content to the various possible structural combinations intended to be expressed in the embodiments of the present invention (for example, the existence of the structure in the corresponding drawings is more of a selective combination method in the embodiments of the present invention, and the corresponding selective combination strategy is implemented based on the textual description). The invention comprises a male connector 1 and a female connector 2, wherein the male connector 1 and the female connector 2 are respectively provided with a first ceramic abutment 11 and a second ceramic abutment 21 containing an optical fiber, and a first metal contact head 12 arranged on at least one side of the first ceramic abutment 11 and a second metal contact head 22 arranged on at least one side of the second ceramic abutment 21. The interlocking structure between the male connector 1 and the female connector 2 includes:

[0069] Near the connecting end of the female connector 2 and the male connector 1, a first notch 23 is provided on the upper surface of the female connector 2 housing, extending axially along a first predetermined distance. A first locking head 24 is provided on the first notch 23. A crossbar with a first locking notch 14 and a pressing portion 15 is connected to the upper surface of the male connector 1 housing via a support rod 13. The first locking notch 14 and the pressing portion 15 are located on opposite sides of the support rod 13. As can be seen from FIG. 2 , the first notch 23 can be formed by thinning the upper surface of the female connector 2. In an alternative embodiment, the upper surface of the female connector 2 can be formed without thinning, and the first notch 23 can be formed directly by fabricating a fence structure 26 as shown in FIG. 2 . Regardless of which method is used to form the first notch 23 as described above, its fundamental function and purpose is to form the first lock head 24 in the first notch 23, and to ensure that after the first lock 14 and the first lock head 24 are locked, the depth of the corresponding first notch 23 (or the fence effect constructed by it) can ensure that external force will not easily impact / squeeze the cross bar located in the first notch 23, affecting the stability of the locked state of the first lock 14 and the first lock head 24.

[0070] After the female connector 2 is connected to the male connector 1, the first locking head 24 and the first locking opening 14 complete the locking, and the first notch 23 accommodates a portion of the crossbar located above the male connector 1. A touch-proof guardrail structure 16, whose height is greater than or equal to that of the pressing portion 15 in the locked state, is provided in the crossbar-accommodating area of ​​the male connector 1. As shown in one implementation in Figure 2, the guardrail structure 16 is a pair of plastic baffles arranged on either side of the pressing portion 15 to prevent vibration of adjacent components of the optoelectronic hybrid connector in a vibrating environment, which could cause the lower pressing portion 15 to be accidentally touched.

[0071] The embodiment of the present invention provides a set of first lock head and first lock port suitable for locking and unlocking between the male connector and the female connector, and associated supporting structures, thereby achieving stability of the connection state of the optoelectronic hybrid connector suitable for use in a vibration environment.

[0072] For earthquake-proof scenarios, simply using the first lock head 24 and the first lock opening 14, along with the accompanying guardrail structure 16 to prevent the pressing portion 15 of the crossbar from being accidentally touched, will not be able to achieve the optimal solution proposed by the present invention. Especially when the connector itself is not large, if the corresponding first lock opening 14 is too close to the end of the crossbar and adjacent to the support rod 13, the torque difference between the position of the pressing portion 15 and the position of the first lock opening 14 relative to the support rod 13 will be large, thereby causing new instability in a vibration environment. In order to solve the problem under this subdivision, the present invention also provides a preferred expansion scheme, specifically as shown in Figures 2, 3 and 4, the first lock head 24 located on the first notch 23 is further provided with a boss-shaped limit portion 25 in the axial extension direction (as shown in Figure 3, where the dotted frame portion almost clearly identifies the limit portion 25 in the example scene of the accompanying figure); in conjunction with it, a long concave groove 17 is made on the cross bar with the first lock opening 14 on the male end connector 1; through the matching observation of Figures 2 and 4, it can be seen that in the preferred scheme, the extension length of the long concave groove 17 directly extends from the end of the cross bar close to the docking port to the area near the support rod 13, covering the position of the first lock opening 14; such a setting not only completes the adjustment of the torque balance between the cross bar where the first lock opening 14 is located and the cross bar owned by the pressing portion 15 compared with the support rod 13, but also More importantly, the elongated concave groove 17 is used to fit over the limiting portion 25 when the first locking head 24 is locked with the first lock opening 14. This allows the first locking head 24 and the first lock opening 14 to maintain a more stable locked state with the auxiliary restraint of the elongated concave groove 17 and the limiting portion 25. Even if an external vibrating object were to break through the fence structure 26 in FIG. 2 and strike the crossbar within the first notch 23, the impact force could be effectively offset by the elongated concave groove 17 fitting over the limiting portion 25, without causing any change in the locking stability between the first locking head 24 and the first lock opening 14.

[0073] In the specific implementation process, the volume of the connector will be much smaller than the intuitive feeling shown in the current figure. Considering the total length of the connector after docking, as shown in Figures 5 and 6, the first notch 23 is provided with a first notch 231 near the docking end of the female connector 2 (the first notch 231 is marked with a dotted frame in Figure 5). The width d1 of the first notch 231 just accommodates the width d2 of the support rod 13. The length L1 of the first notch 231 satisfies that after the male connector 1 and the female connector 2 complete the docking process, the support rod 13 is located in the axial direction and enters the female connector 2 The required distance between the connecting end faces is shown in Figure 7, which is a cross-sectional view of the corresponding male end connector 1 and the female end connector 2 after completion of the connection. In the cross-sectional view, the length L1 is greater than the distance space deeper than the support rod 13, and there is still more surplus space L2. This is because as long as the length L1 of the corresponding first notch 231 maintains a certain distance from the annular groove 18 to be introduced later in the embodiment of the present invention, it will not affect the waterproof and dustproof properties. A little more surplus space can also ensure the adaptive deformation space of the corresponding support rod 13 during the locking and unlocking process (this will be involved in another extended implementation scheme of the present invention later, and will not be elaborated here).

[0074] As the three major problem factors described in the background technology of the present invention, dustproof, waterproof and shockproof, the core shockproof problem has been specifically solved in the above embodiment 1. That is, the traditional connector structure has been overcome. In similar automotive application scenarios (not limited to automotive application scenarios), the vibration of the vehicle itself will bring about the stability problem of the connection structure between the corresponding female connector 2 and the male connector 1. However, as the other two problem factors, dustproof and waterproof, they cannot be effectively achieved with the technical solution structure of the current embodiment 1. For this reason, in combination with the embodiment of the present invention, a better implementation scheme is also provided, which can effectively compensate for the dustproof and waterproof of the remaining two problem factors mentioned above. In conjunction with FIG2 , as shown in FIG8 and FIG9 , a ring groove 18 is provided in the housing area between the connecting end face of the male connector 1 and the support rod 13 ; as shown in FIG9 , the ring groove 18 is used to enclose one or more waterproof rubber rings 3 ( FIG9 only shows a single waterproof rubber ring 3 , but in an optional solution, in order to achieve a better waterproof effect and for easier installation, a combination of multiple narrow and wide waterproof rubber rings 3 may also be used. For example, two or three waterproof rubber rings 3 with circular cross-sections may also be used to achieve a waterproof effect). In the specific implementation process, considering that the first notch 231 is fully utilized as the first stage for the waterproof rubber ring 3 to enter the female connector 2 during the connection process, the thinned area of ​​the first notch 23 is utilized as the second stage for the waterproof rubber ring 3 to enter the female connector 2 during the connection process, thereby ensuring that the corresponding waterproof rubber ring 3 is installed and the male connector 1 and the female connector 2 are connected without feeling the additional damping of the waterproof rubber ring 3, the connection process is completed and the first locking head 24 and the first locking port 14 are locked. In addition to the technical features of the first notch 231 and the first notch 23, the above-mentioned effect requires the following features to ensure that the waterproof rubber ring 3 reaches the predetermined waterproof position in a two-stage arrangement. Specifically, after the male connector 1 and the female connector 2 are connected, the inner surface of the housing where the annular groove 18 abuts the female connector 2 is opposite the outer surface of the female connector 2 where the first notch 23 is located, as shown in FIG9 .

[0075] In the above-mentioned preferred implementation scheme of the present invention, a set of effective waterproof structures is provided for waterproof and dustproof considerations, and the waterproof structure can interact with the above-mentioned locking structure in a structural manner, thereby greatly improving the installation and waterproof effects.

[0076] The principle behind describing the waterproof structure as being structurally linked and interacting with the aforementioned locking structure is also explained with reference to Figure 9. In the cross-sectional view of the connected connector shown in Figure 9, it can be seen that the location of the inner wall of the female connector 2 where the waterproof rubber ring 3 abuts is located precisely at the junction of the first locking head 24 and the limiting portion 25. This way, the waterproof rubber ring 3 exerts a certain lifting effect on the first locking head 24, thereby enhancing the locking effect between the first locking head 24 and the first locking opening 14.

[0077] As shown in Figures 10 and 11, the connecting end of the male connector 1 is provided with a female port 19, wherein the first ceramic abutment 11 is located at the central axis position of the female port 19. In Figure 11, the central position of the central axis of the female port 19 is occupied by the first ceramic abutment 11, thereby forming a structure in which the outer shell of the male connector 1 serves as the outer wall of the female port 19, and the first ceramic abutment 11 serves as the center filling of the female port 19, and the remaining space of the female port 19 constitutes an annular cavity; as shown in Figure 12, the connecting end of the female connector 2 is provided with a male port 27 with a hollow structure in the central axis (it should be noted that only the key area of ​​the male port 27 is marked in Figure 12, and the male port 27 can also be understood as extending to the end face marked B on the left side of Figure 12, but no matter which understanding is used, it does not affect the expression of its technical points, and the difference is only in the accompanying formal difference), wherein the second ceramic abutment 21 is located in the hollow structure of the male port 27. Here, it should be noted that the second ceramic abutment 21 marked in Figure 1 is actually the metal ring on which the second ceramic abutment 21 is sleeved, and the corresponding first ceramic abutment 11 will also be inserted into the corresponding metal ring in Figure 1 after the connection is completed. The reason is that the male end connector 1 and the female end connector 2 are both made of plastic molding due to cost and implementation requirements. Because, in order to ensure the fixed stability of the ceramic abutment, a metal ring is usually added to the abutment position of the first ceramic abutment 11 and the second ceramic abutment 21 (the corresponding metal ring can also be intuitively seen through the explosion diagram shown in Figure 16 later).

[0078] As shown in Figure 13, after the male end connector 1 and the female end connector 2 are connected, the male port 27 and the female port 19 are connected synchronously, and the first ceramic butt joint 11 and the second ceramic butt joint 21 are connected at the same time. In Figure 13, since the male port 27 and the female port 19 have been connected, the area where the male port 27 is located is actually the annular cavity area formed by the female port 19, and for the convenience of simultaneous marking, only the identification position of the female port 19 is set in the remaining area that has not been completely filled by the male port 27. In Figure 13, the first ceramic butt joint 11 and the second ceramic butt joint 21 complete the abutment of their respective cross sections in the hollow structure of the male port 27, thereby completing the cross-sectional docking of the optical fibers located at their respective mid-axis positions.

[0079] In order to achieve that the male end connector 1 and the female end connector 2 can each have multiple specifications, and to ensure that only specifications that match each other can be connected, and that the connection cannot be completed if the specifications between the two are inconsistent. In combination with the embodiment of the present invention, there is also a preferred implementation scheme, in which the outer shell surface of the male end connector 1 is provided with one or more anti-fool protrusions 28 (as shown in Figure 11); the inner wall of the female end connector 2 is provided with one or more anti-fool grooves 29 (as shown in Figure 12) that match the anti-fool protrusions 28 on the outer shell surface; wherein, when there are multiple specifications of male end connectors 1 and female end connectors 2, the positions and quantities of the corresponding anti-fool protrusions 28 and anti-fool grooves 29 ensure that male end connectors 1 and female end connectors 2 from different specifications cannot be connected.

[0080] Specific optional locations for the fool-proofing protrusions 28 and the fool-proofing grooves 29 include: a first method, a preset number of fool-proofing protrusions 28 are provided at a preset position between the annular groove 18 and the connecting end face of the male end connector 1. A second method, a preset number of fool-proofing protrusions 28 are provided at a preset position between the annular groove 18 and the tail end of the male end connector 1; wherein, the fool-proofing grooves 29 are provided to match the fool-proofing protrusions 28. Through practice, it has been verified that of the above two methods, the second method is more suitable for scenarios where both dustproof and waterproof effects need to be considered (wherein, the relevant drawings presented in conjunction with the embodiments of the present invention all adopt this method), and the first method requires that the corresponding fool-proofing grooves 29 extend beyond the location of the annular groove 18, thereby affecting the waterproof rubber ring 3 from playing its due role, because the corresponding fool-proofing grooves 29 will become a potential area for generating gaps.

[0081] During the implementation of the embodiment of the present invention, a variety of optional forms are provided for the pressing portion 15 to meet different unlocking methods.

[0082] As shown in Figure 14, the first form is: the pressing portion 15 is formed by folding the crossbar located on the corresponding side of the support rod 13 into a preset shape; wherein the preset shape includes a bevel 151 connected to the crossbar where the first lock 14 is located, and a crossbar 152 connected to the bevel 151. As shown in Figure 14a, the corresponding male connector 1 and female connector 2 are in a docking and stable loading effect view, while Figure 14b is a corresponding vertical downward pressure applied to the crossbar 152 of the pressing portion 15, which, based on the lever principle, lifts the crossbar containing the first lock 14 on the other side of the support rod 13, thereby unlocking the first lock 14 and the first lock head 24. At this time, as shown in Figure 14, the first lock head 24 is a half-arrow shape that is placed horizontally and only retains one side of the arrow wing 241.

[0083] As shown in FIG. 15 , in the second form, the preset shape is formed by the crossbar located on the corresponding side of the support rod 13 being shaped into a semicircular arc.

[0084] When the upper pressing portion 15 is in the first form, its corresponding unlocking mechanism can be expressed as follows: the support rod 13 is made of hard plastic material, and the cross bars on both sides of the support rod 13 form a seesaw to complete the locking and unlocking between the first lock head 24 and the first lock mouth 14.

[0085] When the upper pressing portion 15 is in the second form, the support rod 13 is made of a relatively hard plastic material with elasticity, and the pressing portion 15 located on one side of the support rod completes the unlocking between the first lock head 24 and the first lock port 14 by pushing horizontally and pressing downward.

[0086] In order to more effectively utilize the characteristics of the unlocking process brought about by the second configuration, preferably, as shown in FIG15 b , the first lock head 24 is in the shape of a half-arrow with only one wing 241 remaining. The half-arrow has a predetermined width d3, and the end of the wing 241 for locking the first lock opening 14 is formed with a locking protrusion 242. The locking protrusion 242 is used to limit the surface shaking of the crossbar around the first lock opening 14 after the first lock head 24 and the first lock opening 14 are locked. Compared with the structure of FIG14 , FIG15 must adopt the semicircular arc structure described above. This can better withstand the horizontal leftward thrust as shown in FIG15 b, causing the first lock opening 24 to decouple from the locking protrusion 242, and then continuously withstand the downward force generated by the horizontal leftward thrust of FIG15 b and the vertical downward thrust (similar to the seesaw effect shown in FIG14 b) as shown in FIG15 c, causing the first lock opening 24 to disengage from the first lock head 14.

[0087] At this point, we can go back to the previous Figure 7, which is a cross-sectional view of the corresponding male end connector 1 and the female end connector 2 after completion of the connection. In the cross-sectional view, the length L1 is made to have more surplus space L2 than the distance space deeper into the support rod 13. More surplus space can also ensure that the corresponding support rod 13 can adaptively withstand the deformation space shown in Figure 15b during the locking and unlocking process.

[0088] Example 2:

[0089] As a complete solution of Example 1 of the present invention, it further considers the better implementation scheme in the optoelectronic hybrid process, and forms a more complete and more beneficial solution based on Example 1; therefore, based on the corresponding shockproof, waterproof and dustproof technical implementations already described in Example 1, Example 2 of the present invention describes the technical details of the implementation of the relevant technical scheme from the perspective of optoelectronic hybrid from the same connector structure.

[0090] In order to ensure the fluency when describing the embodiment 2 of the present invention, the embodiment 2 of the present invention adopts an independent numbering system different from that of the embodiment 1 of the present invention. For the same structural names or similar structural components, those skilled in the art will be able to understand the technical content described when reading this scheme, and will not think that there is no correlation between the two due to the difference in corresponding numbers. The correlation between the structures in the embodiment of the present invention and the structures in embodiment 1 should be reasonably inferred through the structural management of the text and the drawings.

[0091] Embodiment 2 of the present invention provides an optoelectronic hybrid connector, as shown in Figures 16 to 22, including a male connector 4 and a female connector 5 (i.e., corresponding to the male connector 1 and the female connector 5 in Embodiment 1. The contents of the subsequent embodiments of the present invention will not be supplemented in this way to avoid redundant description). The relevant structures will be described in detail below in conjunction with the various figures, including:

[0092] The male end connector 4 is composed of a first outer shell 41, a first plug assembly 42, a central axis assembly 43 and a first tail sleeve 44 that are socketed with each other; as shown in Figures 17, 18 and 19, a rectangular boss 431 is made on at least one horizontal surface of the central axis assembly 43, and the rectangular boss 431 is used to limit the slot 451 of the door-type electrical terminal 45 and provide support for the door columns 452 on both sides; the door columns 452 of the door-type electrical terminal 45 extend beyond the end face of the central axis assembly 43, and are embedded in the accommodating cavity 412 in the first outer shell 41 after assembling the first outer shell 41 and the central axis assembly 43; as shown in Figure 19a, the accommodating cavity 412 is strip-shaped and is made close to the inner wall of the long side parallel to the axial direction of the first outer shell 41.

[0093] The female connector 5 is composed of a second outer shell 51, a second ferrule assembly 52, a power transmission assembly 53 and a second tail sleeve 54, which are socketed with each other; as shown in Figure 20, the power transmission assembly 53 includes a columnar body 531 that is docked with the second ferrule assembly 52, and a positioning member 532 fixed on the columnar body 531, and the positioning member 532 is used to embed the fork-shaped electrical terminal 533; the fork head of the fork-shaped electrical terminal 533 is fixed after passing through the guide hole 511 on the inner wall of the second outer shell 51. As shown in Figure 21, it is a cross-sectional effect diagram of the guide hole 511 on the inner wall of the second outer shell 51 when the fork head of the fork-shaped electrical terminal 533 has not yet passed through it, and the corresponding Figure 22 is a cross-sectional view of the complete assembly of the fork head of the fork-shaped electrical terminal 533 passing through the guide hole 511 on the inner wall of the second outer shell 51.

[0094] When the male connector 4 and the female connector 5 are connected, the first ferrule assembly 42 is docked with the second ferrule assembly 52, and the contacts on both sides of the fork head of the fork-shaped electrical terminal 533 are respectively in contact with the two side posts 452 of the door-shaped electrical terminal 45.

[0095] The embodiment of the present invention proposes a set of optoelectronic hybrid connectors suitable for shockproof scenarios, which cleverly integrates the electrical connection structure into the traditional pure optoelectronic electrolyzer. Moreover, during the implementation process, there is no need to increase the volume of the optical interface. The original structure's own characteristics are fully reused, and the position for the layout of the electrical connection structure is extracted from it. It can not only ensure that there will be no leakage problems, but also ensure that the strength of the connector itself will not be reduced after the integration of optoelectronics.

[0096] As shown in Figure 17 , the rectangular boss 431 on the corresponding central axis assembly 43 is only shown on one side. In the specific embodiment, the difference between providing the rectangular boss 431 on one side or providing the rectangular boss 431 on both sides is the difference in the number of gate-type electrical terminals 45 that can be arranged. In other words, the choice of providing the rectangular boss 431 on one side or providing two rectangular bosses 431 on opposite sides for different power supply structures should be understood as a core innovation of the present invention that can be made according to the needs of the scene and should fall within the scope of protection of the present invention. Among them, rectangular bosses 431 are symmetrically made on the upper and lower horizontal planes of the central axis component 43. At this time, for the convenience of processing, that is, for the stability of installing the door-type electrical terminal 45 on the central axis component 43, a limiting protrusion 432 is set on the side of the door beam 453 close to the fixed door-type electrical terminal 45 on the corresponding horizontal plane to limit the door beam 453. In addition, referring to Figures 17 and 18, the height d5 of the door beam 453 should be as close as possible to the distance d4 from the limiting protrusion 432 to the edge of the rectangular boss 431, so that the fixing effect of the limiting protrusion 432 is optimized.

[0097] In the implementation of this embodiment of the present invention, to achieve better dustproofing, the first tail sleeve 44 is preferably cast. This has the greatest advantage of filling gaps between components during the casting process, thus providing enhanced dustproofing. In this case, the stopper protrusions 432 proposed in the improved solution can be further reused in the current solution of casting the first tail sleeve 44. Furthermore, as shown in Figure 17 , one or more anti-pull protrusions 433 are symmetrically provided on the left and right sides of the central shaft assembly 43. These one or more anti-pull protrusions 433, in conjunction with the stopper protrusions 432, act together with the cast first tail sleeve 44 to lock it against pull in all four directions: vertically, horizontally, and horizontally. This way, regardless of the direction in which the first tail sleeve 44 is bent or pulled, the stopper protrusions 432 and / or the anti-pull protrusions 433 in the supporting area act as a restraint, preventing the first tail sleeve 44 from dislodging from its original assembly position.

[0098] As shown in Figures 23, 23a, and 23b, a channel 434 is provided between each horizontally-surfaced stopper 432 for passing the conductor 63. The height of the stopper 432 is consistent with the surface height h of the conductor 6 passing through the channel 434. The width d6 of the channel 434 is less than a predetermined value from the diameter d7 of the conductor 6. As shown in Figure 23c, once the weld between the conductor 63 end and the door beam 453 is complete, the corresponding weld area and the connection area between the conductor end and the protective cover of the conductor 6 will have the same effect as the anti-pull protrusion 433, thereby forming, together with the stopper 432, the equivalent effect of the multi-point anti-pull protrusion 433.

[0099] In order to achieve the docking effect of the ferrule assembly between the male connector 4 and the female connector 5, and also considering the error between the shell components, it is most effective to use the spring 46 as the guarantee of the mutual contact force between the two ferrule assemblies. Therefore, in combination with the embodiment of the present invention, there is another possible implementation, as shown in Figures 23 and 24, the male connector 4 also includes a spring 46, and one side of the limit block 421 on the first ferrule assembly 42 is in contact with the spring 46 limit groove of the central shaft assembly 43 through the spring 46; the other side of the limit block 421 directly contacts the ferrule guide groove 411 preset on the first shell 11.

[0100] As shown in Figure 25 , the two outer walls 1121 of the accommodating cavity 412 are formed by the outer corner contours of the first outer shell 41. The remaining outer wall 1122 of the accommodating cavity 412 is formed by the inner wall pattern behind the secondary female port. The last side 1123 of the accommodating cavity 412 directly communicates with the secondary female port; this last side is a reserved channel for the fork-type electrical terminal 533 to enter and establish electrical communication with the gate-type electrical terminal 45. The location of the corresponding secondary female port is marked with semi-transparent shading in Figure 25 .

[0101] As shown in Figure 25 , in the preferred embodiment, the inner wall pattern is formed with a semicircular groove aligned with the direction of the accommodating cavity 412. The semicircular groove is provided to provide an airflow channel to assist in heat dissipation from the door post 452 of the door-type electrical terminal 45 and to reduce friction during insertion of the door post 452 of the door-type electrical terminal 45, thereby facilitating installation.

[0102] After focusing on the possible details of implementing the expansion solution for the male end connector 4 above, the following will start from the female end connector 5 to fully explain the improvement ideas that may be introduced in the implementation solution of the embodiment of the present invention, as well as the supporting principles and original intentions.

[0103] Figure 20 illustrates a preferred structural implementation of a positioning member 532 according to an embodiment of the present invention. While Figure 20 was cited above as a schematic illustration of the supporting structure of the power transmission assembly 53, the preferred embodiment of the structure in Figure 20 was not elaborated upon in detail. Therefore, as a preferred implementation, the structure on the positioning member 532 for embedding the fork-shaped electrical terminal 533 includes a rectangular groove 5321 disposed therein. A portion of the rectangular groove 5321, distal from the fork, is provided with a skylight 5322, providing a welding area for the wire 6 and the fork-shaped electrical terminal 533.

[0104] Furthermore, the setting of the skylight 5322 retains the shell portion of the positioning piece 532 located at the end of the rectangular groove 5321, thereby forming an abutment limit for the embedded fork-type electrical terminal 533 during the embedding process, and absorbing the abutment force of the door-type electrical terminal 45 acting on the male end connector 4 and the female end connector 5 when they are connected.

[0105] In order to further adapt to the above-mentioned considerations of the digestion resistance force, as shown in Figure 26, the fork-shaped electrical terminal 533 is made into a Z shape, wherein the upper horizontal part is embedded in the positioning member 532, and the lower horizontal part of the fork-shaped electrical terminal 533 is exposed to the outside; the connecting member between the upper horizontal part and the lower horizontal part is a vertical part, wherein the vertical part is used to buffer the impact force of the fork-shaped electrical terminal 533 and the door-type electrical terminal 45 when the male end connector 4 and the female end connector 5 are connected.

[0106] The electrical connection structure involved in the embodiment of the present invention also has its own strength, and in the preferred implementation scheme, the damping and convenience during the corresponding assembly process are also optimized.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
