Description

Technical Field

[0001] The present invention relates to the technical field of optical communication, and in particular to an optoelectronic hybrid connector. Background Art

[0002] Optical fiber communication is a communication method that uses light waves as information carriers and optical fibers as transmission media. The field of optical communication technology usually involves devices such as connectors, optical modules, and adapters.

[0003] Among them, the connector is an optical passive device that realizes the connection between optical fibers. It has the function of connecting between optical fibers, optical fibers and active devices, optical fibers and equipment, optical fibers and other passive devices, and optical fibers and instruments. As a very important optical signal interface device in optical fiber communication, the optical module has an optical interface and an electrical interface. The optical interface is connected to the optical fiber to transmit optical signals, and the electrical interface is connected to the external communication terminal equipment. The adapter is used to transfer two connectors. Especially in the optical fiber equipment represented by 5G base stations and FTTR equipment, there are a large number of plug-in optoelectronic lines in the scenario where remote power supply is required while communicating at a wide bandwidth. Due to the separate settings of optoelectronics, there are many connectors and they are divided into two categories, optoelectronics, which need to be correctly paired one by one, resulting in cumbersome operations during installation and maintenance, and prone to plug-in errors.

[0004] On the other hand, at the terminal end of the FTTH network, the traditional copper wire transmits network signals and supplies power to the terminal end at the same time. As the FTTH optical network develops into the FTTR optical network, for example, the vehicle-mounted terminal needs to meet the needs of autonomous driving and artificial intelligence interaction, and the terminal end has higher and higher bandwidth requirements. The traditional copper wire signal transmission capacity can no longer meet the terminal end bandwidth requirements; the terminal end signal transmission medium of the FTTR network is copper retreat and light advance, and the power supply of the terminal end is provided by the cable, which is already a general trend; in order to connect these composite cables, one solution of the prior art is that the optical connector and the electrical connector are designed independently, and the optical connector and the optical adapter are plugged and coupled to realize the optical signal docking; the electrical connector and the electrical adapter are plugged and coupled to realize the electrical signal coupling docking. However, the use of separate optical connectors and electrical connectors requires plugging and unplugging twice to complete the connection with the adapter. The solution is to use optoelectronic hybrid connectors and optoelectronic hybrid adapters, but in some existing solutions, the electrical terminals of the connectors are partially exposed to the outside. In actual use, there is a certain risk of electric shock and human safety issues.

[0005] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Summary of the invention

[0064] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] Embodiment 1:

[0066] Embodiment 1 of the present invention provides an optoelectronic hybrid connector, such as Figure 1-Figure 7As shown, it includes a male connector 1 and a female connector 2. Next, the relevant structures will be specifically described in combination with various drawings, including:

[0067] The male connector 1 is composed of a first outer shell 11, a first plug assembly 12, a middle shaft assembly 13 and a first tail sleeve 14 which are connected to each other; Figure 2 , Figure 3 and Figure 4 As shown, a rectangular boss 131 is made on at least one horizontal surface of the central axis component 13, and the rectangular boss 131 is used to limit the notch 151 of the door-type electrical terminal 15 and provide support for the door posts 152 on both sides; the door posts 152 of the door-type electrical terminal 15 extend beyond the end surface of the central axis component 13, and are embedded in the accommodating cavity 112 in the first outer shell 11 after the first outer shell 11 and the central axis component 13 are assembled; Figure 4a As shown, the accommodating cavity 112 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 11 .

[0068] The female connector 2 is composed of a second outer shell 21, a second plug assembly 22, a power transmission assembly 23 and a second tail sleeve 24 which are connected to each other; Figure 5 As shown, the power transmission component 23 includes a columnar body 231 docked with the second plug assembly 22, and a positioning member 232 fixed on the columnar body 231, and the positioning member 232 is used to embed the fork-shaped electrical terminal 233; the fork head of the fork-shaped electrical terminal 233 is fixed after passing through the guide through hole 211 on the inner wall of the second outer shell 21, as shown in FIG. Figure 6 The figure shows a cross-sectional view of the guide through hole 211 on the inner wall of the second outer shell 21 before the fork of the fork-shaped electrical terminal 233 passes through. Figure 7 This is a cross-sectional view of the complete assembly of the fork head of the fork-shaped electrical terminal 233 passing through the guide through hole 211 on the inner wall of the second outer shell 21;

[0069] When the male connector 1 and the female connector 2 are connected, the first plug assembly 12 is connected to the second plug assembly 22, and the contacts on both sides of the fork head of the fork-shaped electrical terminal 233 are respectively in contact with the two side posts 152 of the door-shaped electrical terminal 15.

[0070] 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 electrolyte. In addition, 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 therefrom. Not only can it be ensured that there will be no leakage problems, but also the strength of the connector itself will not be reduced after the integration of optoelectronics.

[0071] like Figure 2 As described above, the rectangular boss 131 on the corresponding central axis component 13 is only shown to be set on one side. In the specific trial scheme, the difference between setting the rectangular boss 131 on one side or setting the rectangular boss 131 on both sides is the difference in the number of corresponding door-type electrical terminals 15 that can be arranged, that is, the rectangular boss 131 can be selectively set on one side or two rectangular bosses 131 can be set relatively to each other for different power supply structures. They should be understood as choices that can be made according to scene requirements under the core innovation of the present invention, and should all fall within the protection scope of the present invention. Among them, rectangular bosses 131 are symmetrically made on the upper and lower horizontal planes of the central axis component 13. At this time, for the convenience of processing, that is, for the stability of installing the door-type electrical terminal 15 on the central axis component 13, a limiting protrusion 132 is set on the corresponding horizontal plane close to the door beam 153 side where the door-type electrical terminal 15 is fixed, which is used to limit the door beam 153, and, with reference to Figure 2 and Figure 3 The height d2 of the door beam 153 should be as close as possible to the distance d1 from the limiting protrusion 132 to the edge of the rectangular boss 131, so that the fixing effect of the limiting protrusion 132 is optimal.

[0072] In the process of implementing the embodiment of the present invention, in order to achieve a better dustproof effect, the corresponding first tail sleeve 14 is preferably formed by casting. The biggest advantage of this is that the gaps between the components can be filled by the casting process, which has a better dustproof effect. At this time, the limit protrusion 132 proposed in the above improved solution can be further reused in the current solution of implementing the first tail sleeve 14 by casting. In addition, further Figure 2 As shown, one or more anti-pull protrusions 133 are symmetrically arranged on the left and right sides of the central shaft assembly 13, and the one or more anti-pull protrusions 133 act together with the limiting protrusions 132 on the first tail sleeve 14 formed by casting, forming a locking mechanism for the first tail sleeve 14 against pulling in four directions: up, down, left, and right. In this way, no matter in which direction the first tail sleeve 14 is bent and pulled, the matching area has the limiting protrusions 132 and / or the anti-pull protrusions 133 as objects to limit the first tail sleeve 14 from being separated from the original assembly position and play a corresponding pulling role.

[0073] like Figure 8 , Figure 8a and Figure 8b As shown, a channel 134 is provided in the middle of each limiting protrusion 132 on the horizontal plane for passing the wire 33; wherein the height of the limiting protrusion 132 is consistent with the surface height h of the wire 3 passing through the channel 134; and the width d3 of the channel 134 is less than the preset value of the diameter width d4 of the wire 3. Figure 8cOnce the welding between the wire end of the wire 33 and the door beam 153 is completed, the corresponding welding area and the connection area between the wire end and the protective cover of the wire 3 will have the same effect as the anti-pull protrusion 133, and after being combined with the limiting protrusion 132, it will form the same effect as the multi-point anti-pull protrusion 133.

[0074] In order to achieve the docking effect of the plug assembly between the male connector 1 and the female connector 2, and also considering the error between the shell components, it is most effective to use the spring 16 as the guarantee of the mutual contact force between the two plug assemblies. Therefore, in combination with the embodiment of the present invention, there is another possible implementation, such as Figure 8 and Fig. 9 As shown, the male end connector 1 also includes a spring 16, and one side of the limit block 121 on the first plug assembly 12 abuts against the spring 16 limit groove of the central axis assembly 13 through the spring 16; the other side of the limit block 121 directly abuts against the preset plug guide groove 111 on the first shell 11.

[0075] like Fig.10 As shown, the two outer walls 1121 of the accommodating cavity 112 are respectively formed by the outer shell corner contours of the first outer shell 11, and the remaining outer wall 1122 of the accommodating cavity 112 is formed by the inner wall pattern behind the female port, and the last side 1123 of the accommodating cavity 112 is directly interconnected with the female port space; wherein, the last side is a reserved channel for the fork-type electrical terminal 233 to enter and complete electrical interconnection with the door-type electrical terminal 15. Fig.10 The position area of ​​the corresponding slave port is marked with a semi-transparent shadow; in Example 2 of the present invention, the slave port will be further clearly introduced in the process of explaining other structures of the connector proposed by the present invention from a complete technical perspective.

[0076] like Fig.10 As shown, in the preferred implementation, a semicircular groove is made on the inner wall pattern in the same direction as the accommodating cavity 112. The semicircular groove is made, on the one hand, to provide an air flow groove to assist the heat dissipation on the door column 152 of the door-type electrical terminal 15, and on the other hand, to reduce the corresponding friction during the insertion of the door column 152 of the door-type electrical terminal 15, making the installation process more convenient.

[0077] After focusing on the possible details of implementing the expansion scheme for the male end connector 1 above, the following will start from the female end connector 2 to fully explain the improvement ideas that may be introduced in the implementation scheme of the embodiment of the present invention, as well as the supporting principles and original intentions.

[0078] like Figure 5 As shown in FIG. 1 , a preferred structural implementation of the positioning member 232 provided in an embodiment of the present invention is shown. Figure 5 At the time, it is only a schematic supporting structure display of the power transmission component 23, and there is no Figure 5 Therefore, as a preferred implementation scheme, the structure on the positioning member 232 for embedding the fork-shaped electrical terminal 233 includes a rectangular groove 2321 provided on the positioning member 232, and a section of the corresponding rectangular groove 2321 away from the fork head is provided with a skylight 2322 for providing a welding area for the wire 3 and the fork-shaped electrical terminal 233.

[0079] Furthermore, the provision of the skylight 2322 retains the shell portion of the positioning member 232 located at the end of the rectangular groove 2321, thereby forming an abutment limit for the embedded fork-type electrical terminal 233 during the embedding process, and absorbing the abutment force of the door-type electrical terminal 15 when the male end connector 1 and the female end connector 2 are connected.

[0080] In order to further adapt to the above considerations of digestive resistance, Fig.11 As shown, the fork-type electrical terminal 233 is made into a Z shape, wherein the upper horizontal portion is embedded in the positioning member 232, and the lower horizontal portion of the fork-type electrical terminal 233 is exposed to the outside; the connecting member between the upper horizontal portion and the lower horizontal portion is a vertical portion, wherein the vertical portion is used to buffer the impact force of the fork-type electrical terminal 233 and the door-type electrical terminal 15 when the male-end connector 1 and the female-end connector 2 are connected.

[0081] 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 in the corresponding assembly process are also designed and optimized.

[0082] Embodiment 2:

[0083] As a complete solution of Example 1 of the present invention, it further considers technical factors of shockproof, waterproof and dustproof, and forms a more complete solution based on Example 1; therefore, based on the corresponding optoelectronic hybrid technology implementation described in Example 1, the embodiment of the present invention describes the technical details of the implementation of the relevant technical solution from the same connector structure, focusing on shockproof, waterproof and dustproof.

[0084] In order to ensure the fluency when describing the scheme of Example 2 of the present invention, Example 2 of the present invention adopts an independent numbering system different from that of Example 2 of the present invention, wherein the same structural names or similar structural components are used. Those skilled in the art can understand the technical content described in this scheme when reading it, and will not think that there is no correlation between the two due to the difference in corresponding numbers. The correlation between the structure in the embodiment of the present invention and the structure in Example 1 should be reasonably inferred through the structural management of the text and the drawings.

[0085] Embodiment 2 of the present invention provides a shockproof optoelectronic hybrid connector, such as Fig.12 and Fig.13 As shown, Fig.12 yes Fig.13 After arranging the ceramic ferrules on the axis, Fig.13 The sectional view structure after the central axis section is performed along the A-A' section line shown in the figure. Among them, unless otherwise specified, the subsequent relevant sectional views in the embodiments of the present invention are sectional views obtained by vertical cutting according to the central axis where the ceramic insert is located. It should be noted that the protection scope of the embodiments of the present invention needs to be based on the text description of the specification, and the corresponding drawings are example structures presented as relatively complete solutions. Therefore, in comparison, the drawings in the specification are based on the effects presented by the content of the complete text solution, so the content of the drawings in the specification should not be interpreted too much, and the complete structural content should be limited to the various combination schemes composed of possible structures that the text of the embodiments of the present invention wants to express (for example, the existence of the structure in the corresponding drawings is more of a selection combination method in the embodiments of the present invention, and the corresponding selection combination strategy is implemented according to the text content description). The male connector 4 and the female connector 5 are respectively provided with a first ceramic abutment 41 and a second ceramic abutment 51 containing optical fibers (corresponding to the male connector 1 and the female connector 5 in Embodiment 1, and the contents of the subsequent embodiments of the present invention will not be supplemented in this way to avoid redundant description), 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 4 and the female connector 5 includes:

[0086] Near the connecting end of the female connector 5 and the male connector 4, a first notch 53 with a first preset length is arranged axially on the upper surface of the female connector 5 shell, and a first lock 54 is arranged on the first notch 53; a cross bar with a first lock 44 and a pressing portion 45 is connected to the upper surface of the male connector 4 shell through a support rod 43; wherein the first lock 44 and the pressing portion 45 are relatively located on both sides of the support rod 43. Fig.13 As can be seen in the figure, the first notch 53 can be formed by thinning the upper shell of the female end connector 5; in an optional solution, the upper shell of the female end connector 5 can be made without thinning, and the female end connector 5 can be made directly. Fig.13The first notch 53 is formed after the fence structure 56 shown in the figure is formed. Regardless of which method of forming the first notch 53 described above is adopted, its fundamental function and purpose is to be able to form the first locking head 54 in the first notch 53, and to ensure that after the first locking port 44 and the first locking head 54 are locked, the depth of the corresponding first notch 53 (or the fence effect constructed by it) can ensure that the external force will not easily hit / compress the cross bar located in the first notch 23, affecting the stability of the locked state of the first locking port 44 and the first locking head 54.

[0087] After the female connector 5 is connected to the male connector 4, the first locking head 54 and the first locking port 44 complete the locking, and the first notch 53 accommodates part of the crossbar located above the male connector 4; wherein, an anti-touch guardrail structure 46 having a height greater than or equal to that of the pressing portion 45 in the locked state is provided in the crossbar accommodating area of ​​the male connector 4. Fig.13 In one implementation shown, the guardrail structure 46 is a pair of plastic baffles arranged on both sides of the pressing portion 45, so as to prevent vibration of some components adjacent to the optoelectronic hybrid connector in a vibration environment, resulting in the pressing portion 45 being accidentally touched.

[0088] 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 end connector and the female end connector, and their associated supporting structures, thereby achieving the stability of the connection state of the optoelectronic hybrid connector suitable for medium vibration environment.

[0089] For earthquake-proof scenarios, only using the first lock head 54 and the first lock port 44, as well as the matching guardrail structure 46 to prevent the pressing portion 45 of the crossbar from being accidentally touched, will not be able to achieve the effect of the optimal solution proposed by the present invention. Especially when the connector itself is not large in size, if the corresponding first lock port 44 is too close to the end of the crossbar and adjacent to the support rod 43, the torque difference between the position of the corresponding pressing portion 45 and the position of the first lock port 44 compared to the support rod 43 will be larger, which will bring new instability in a vibration environment. In order to solve the problem under this subdivision, the present invention also provides a preferred expansion solution, as follows Fig.13 , Fig.14 and Fig.15 As shown, the first lock head 54 located on the first notch 53 is also provided with a boss-shaped limiting portion 55 in the axial extension direction (as shown in FIG. Fig.14 As shown, the dotted line frame portion almost clearly identifies the limit portion 55 in the example scene of the attached figure); matched, a long concave groove 47 is made on the crossbar located on the male end connector 4 and having the first lock 44; through Fig.13 and Fig.15Through observation, it can be seen that in the preferred embodiment, the extension length of the long concave groove 47 directly extends from the end of the cross bar near the docking port to the area near the support rod 43, covering the position of the first lock 44; such a configuration not only completes the adjustment of the moment balance between the cross bar where the first lock 44 is located and the cross bar owned by the pressing portion 45 compared with the support rod 43, but more importantly, the long concave groove 47 is used to be sleeved on the limiting portion 55 when the first locking head 54 is locked with the first lock 44, so that the locking state between the first locking head 54 and the first lock 44 can achieve a better stability with the auxiliary restriction of the long concave groove 47 and the limiting portion 55. At this time, even if there is an external vibration object that can break through Fig.13 When the middle fence structure 56 hits the crossbar in the first slot 53 , the impact force can be effectively offset based on the long concave slot 47 being sleeved on the limit portion 25 structure without causing changes in the locking stability of the first lock head 54 and the first lock slot 44 .

[0090] In the specific implementation process, the volume of the connector will be much smaller than the intuitive feeling shown in the current figure, so consider the total length of the connector after connection, such as Fig.16 and Fig.17 As shown, the first notch 53 is provided with a first notch 531 (at Fig.16 The first notch 531 is marked with a dotted frame), the width d5 ​​of the first notch 531 just accommodates the width d6 of the support rod 43, and the length L1 of the first notch 531 satisfies the distance required for the support rod 43 to enter the connection end face of the female connector 5 in the axial direction after the male connector 4 and the female connector 5 are connected. Fig.18 The figure shows a cross-sectional view of the corresponding male-end connector 4 and the female-end connector 5 after the connection is completed, wherein the length L1 is made to have more surplus space L2 than the distance space deeper than the support rod 43. This is because as long as the length L1 of the corresponding first notch 531 maintains a certain distance from the annular groove 48 to be introduced later in the embodiment of the present invention, it will not affect the waterproof and dustproof properties. More surplus space can also ensure the adaptive deformation space of the corresponding support rod 43 during the locking and unlocking process.

[0091] As the three major problem factors described in the background technology of the present invention, dustproof, waterproof and shockproof, the above embodiment 1 has specifically solved the most core shockproof problem, that is, it overcomes the traditional connector structure. 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 5 and the male connector 4. Combined with Fig.13 , Fig.19 and Fig. 20 As shown, a ring groove 48 is provided in the housing area between the connecting end surface of the male connector 4 and the support rod 43; Fig. 20 As shown, the ring groove 48 is used to enclose one or more waterproof rubber rings 6 (in Fig. 20 It is only shown in the form of a waterproof rubber ring 6, but in the optional scheme, in order to achieve a better waterproof effect and to facilitate installation, a combination of multiple narrow and wide waterproof rubber rings 6 can be used. For example, two or three waterproof rubber rings 6 with circular cross-sections can be directly used to achieve the waterproof effect.). In the specific implementation process, considering that the first notch 531 is fully utilized as the first stage of the waterproof rubber ring 6 entering the female connector 5 during the connection process, the thinning area of ​​the first notch 53 is used as the second stage of the waterproof rubber ring 6 entering the female connector 5 during the connection process, thereby ensuring that the corresponding installed waterproof rubber ring 6 can be connected with the male connector 4 and the female connector 5. In the case of almost no additional damping brought by the waterproof rubber ring 6, the connection process is completed to achieve the locking of the first lock head 54 and the first lock port 44. In addition to the technical features of the first notch 531 and the first notch 53, the above-mentioned effect also needs to have the following features to ensure the two-stage setting for the waterproof rubber ring 6 to reach the preset waterproof position. That is, after the male connector 4 and the female connector 5 are connected, the inner surface of the housing where the annular groove 48 abuts against the female connector 5 is opposite to the outer surface of the female connector 5 where the first notch 53 is located. Fig. 20 shown.

[0092] 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.

[0093] The reason why it is described as a waterproof structure that can interact with the above-mentioned locking structure is also explained by Fig. 20 to explain. Fig. 20 In the cross-sectional view after the connection is completed, it can be seen that the inner wall position of the female end connector 5 abutted by the corresponding waterproof rubber ring 6 is exactly located at the connection between the first lock head 54 and the limiting portion 55. In this way, the waterproof rubber ring 6 will have a certain lifting effect on the first lock head 54, thereby enhancing the locking effect between the first lock head 54 and the first lock port 44.

[0094] like Fig.21 and Fig. 22As shown, the male connector 4 is provided with a female port 49 at its connecting end, wherein the first ceramic abutment 41 is located at the center of the central axis of the female port 49. Fig.21 The central axis position of the female port 49 is occupied by the first ceramic abutment 41, so that a structure is formed in which the outer wall of the female port 49 is formed by the shell of the male connector 4, and the center of the female port 49 is filled by the first ceramic abutment 41, and the remaining space of the female port 49 constitutes an annular cavity; Fig.23 As shown, the connecting end of the female connector 5 is provided with a male port 57 having a hollow structure in the middle axis (it should be noted that Fig.23 Only the key area from the male port 57 is marked, and it can also be understood as extending from the male port 57 to Fig.23 The end face marked with B on the left side, but no matter which understanding is used, it does not affect the expression of its technical points, and the difference is only in the form of attachment), wherein the second ceramic abutment 51 is located in the hollow structure of the male port 57. Here, it is necessary to supplement Fig.23 The second ceramic abutment 51 in the figure is actually the metal ring that the second ceramic abutment 51 is sleeved with, and the corresponding first ceramic abutment 41 will also be inserted into the corresponding metal ring after the connection is completed. Fig.23 The reason is that the male connector 4 and the female connector 5 are both made of plastic molding due to cost and implementation requirements. Because, in order to ensure the fixing stability of the ceramic abutment, a metal ring is usually added to the abutment position of the first ceramic abutment 41 and the second ceramic abutment 51 (the corresponding metal ring can also be inserted through the front Figure 1 The exploded diagram shown is intuitive).

[0095] like Fig.24 As shown, after the male connector 4 and the female connector 5 are connected, the male port 57 and the female port 49 are connected synchronously, and the first ceramic abutment joint 41 and the second ceramic abutment joint 51 are connected simultaneously. Fig.24 In the figure, since the male port 57 and the female port 49 have been connected, the area where the male port 57 is located is actually the annular cavity area formed by the female port 49. For the convenience of simultaneous marking, only the marking position of the female port 49 is set in the remaining area that has not been completely filled by the male port 57. Fig.24 In the embodiment, the first ceramic abutment joint 41 and the second ceramic abutment joint 51 complete the abutment of their respective cross sections in the hollow structure of the male port 57, thereby completing the cross-sectional docking of the optical fibers located at their respective mid-axis positions.

[0096] In order to realize that the male connector 4 and the female connector 5 can each have multiple specifications and ensure that only specifications that match each other can be connected, and the connection cannot be completed if the specifications 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 connector 4 is provided with one or more foolproof protrusions 58 (such as Fig. 22 The inner wall of the female connector 5 is provided with one or more fool-proof grooves 59 (such as Fig.23 Wherein, when there are multiple specifications of male end connectors 4 and female end connectors 5, the positions and quantities of the corresponding fool-proof protrusions 58 and fool-proof grooves 59 ensure that male end connectors 4 and female end connectors 5 from different specifications cannot be connected.

[0097] Specific optional locations for the fool-proof protrusions 58 and fool-proof grooves 59 include: In the first way, a preset number of fool-proof protrusions 58 are set at a preset position between the annular groove 48 and the connecting end face of the male connector 4. In the second way, a preset number of fool-proof protrusions 58 are set at a preset position between the annular groove 18 and the tail end of the male connector 4; wherein the fool-proof grooves 59 are set to match the fool-proof protrusions 58. Through practice, it has been verified that among the above two ways, the second way 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 way), and the first way requires that the corresponding fool-proof grooves 59 extend beyond the location of the annular groove 48, which will affect the waterproof rubber ring 6 from playing its due role, because the corresponding fool-proof grooves 59 will become a potential area for generating gaps.

[0098] In the process of implementing the embodiment of the present invention, a variety of optional forms are also provided for the pressing portion 45 to meet different unlocking methods.

[0099] like Fig.25 As shown in the first form: the pressing portion 45 is formed by folding the cross bar located at the corresponding side of the support rod 43 according to a preset shape; wherein the preset shape includes a bevel 451 connected to the cross bar where the first lock 44 is located, and a cross side 452 connected to the bevel 451. Fig.25 a shows the effect of the male connector 4 and the female connector 5 being stably connected and loaded. Fig.25 b is a schematic diagram showing the effect of applying a vertical downward pressure to the horizontal side 452 of the pressing portion 45, so that the horizontal bar including the first lock 44 on the other side of the support rod 43 is lifted up based on the lever principle, thereby unlocking the first lock 44 and the first lock head 54. Fig.25As shown, the first locking head 54 is in a flat half-arrow shape with only one side of the arrow wing 541 retained.

[0100] like Fig.26 As shown, the second form: the preset shape is formed by the cross bar located on the corresponding side of the support rod 43 being shaped into a semicircular arc.

[0101] When the upper pressing portion 45 is in the first form, its corresponding unlocking mechanism can be expressed as follows: the support rod 43 is made of hard plastic material, and the cross bars 13 located on both sides of the support rod constitute a seesaw to complete the locking and unlocking between the first lock head 54 and the first lock port 44.

[0102] When the upper pressing portion 45 is in the second form, the support rod 43 is made of a relatively hard plastic material with elasticity, and the pressing portion 45 located on one side of the support rod completes the unlocking between the first locking head 54 and the first locking port 44 by pushing horizontally and pressing downward.

[0103] In order to more effectively utilize the characteristics of the unlocking action process brought by the second form, it is preferred that Fig.26 As shown in FIG. 2 , the first lock head 54 is a flat half-arrow shape with only one side of the arrow wing 541 retained, wherein the half-arrow shape has a preset width d7, and a locking protrusion 542 is made at the end of the arrow wing 541 for locking the first lock port 44, and the locking protrusion 542 is used to limit the shaking of the surface of the cross bar around the first lock port 44 after the first lock head 54 and the first lock port 44 are locked. Fig.25 The structure of Fig.26 The semicircular arc structure described above must be used in order to better undertake the following Fig.26 b pushes leftward horizontally, so that the first locking port 54 is decoupled from the locking protrusion 542, and then the first locking port 54 is connected in a continuous manner. Fig.26 c's horizontal leftward thrust and vertical downward thrust from 26b (similar to Fig.25 b) together form an oblique downward force, causing the first lock opening 54 to disengage from the first lock head 44.

[0104] At this point, you can go back to the previous Fig.18 As shown in FIG. 1 , it is a cross-sectional view of the male connector 1 and the female connector 5 after the connection is completed, wherein the length L1 is made to have a surplus space L2 compared to the distance space of the support rod 43. The surplus space can also ensure that the corresponding support rod 43 can adaptably withstand the load during the locking and unlocking process. Fig.26 b The deformation space shown.

[0105] 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 protection scope of the present invention.
