Description

Technical Field

[0001] The present invention relates to the technical field of optical communication technology, and in particular to a shockproof 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, in the scenario where the FTTH network is the terminal end of the network, the traditional copper wire transmits the network signal and supplies power to the terminal end at the same time. With the development of the FTTH optical network to 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 requirements for bandwidth. The traditional copper wire signal transmission capacity can no longer meet the bandwidth requirements of the terminal end; FTTR uses the terminal end of the network as the signal transmission medium, copper retreats and optical advances, 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] On the other hand, the precision of the optical fiber 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, which affects the coupling accuracy of the optical channel of the fiber optic connector.

[0006] Another aspect is that in the process of technological transition, technological achievements are often not achieved all at once. Often, the old technology and the new technology coexist for a long time before they are completely replaced by the new technology. Therefore, how to achieve the compatibility and matching of pure optical docking connectors, pure electric docking connectors and optoelectronic hybrid connectors is also a major technical problem that the industry needs to solve.

[0007] 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.

[0069] Embodiment 1:

[0070] Embodiment 1 of the present invention provides a shockproof optoelectronic hybrid connector, such as Figure 1 and Figure 2 As shown, Figure 1 yes Figure 2 After arranging the ceramic ferrules on the axis, Figure 2 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 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, and the interlocking structure between the male connector 1 and the female connector 2 comprises:

[0071] Near the connecting end of the female connector 2 and the male connector 1, a first notch 23 with a first preset length is arranged axially on the upper surface of the female connector 2 housing, and a first lock 24 is arranged on the first notch 23; a cross bar with a first lock 14 and a pressing portion 15 is connected to the upper surface of the male connector 1 housing through a support rod 13; wherein the first lock 14 and the pressing portion 15 are relatively located on both sides of the support rod 13. Figure 2 As can be seen in the figure, the first notch 23 can be formed by thinning the upper shell of the female end connector 2; in an optional solution, the upper shell of the female end connector 2 can be formed without thinning, and the upper shell of the female end connector 2 can be directly made as shown in the figure. Figure 2 The first notch 23 is formed after the fence structure 26 shown in the figure. Regardless of which method of forming the first notch 23 described above is adopted, 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 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 lock 14 and the first lock head 24.

[0072] After the female connector 2 is connected to the male connector 1, the first locking head 24 and the first locking port 14 complete the locking, and the first notch 23 accommodates part of the crossbar located above the male connector 1; wherein, an anti-touch guardrail structure 16 having a height 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. Figure 2 In one implementation shown, the guardrail structure 16 is a pair of plastic baffles arranged on both sides of the pressing portion 15, so as to prevent vibration of some components adjacent to the optoelectronic hybrid connector in a vibration environment, resulting in the lower pressing portion 15 being accidentally touched.

[0073] 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 a vibration environment.

[0074] For earthquake-proof scenarios, only using the first lock head 24 and the first lock opening 14, as well as the matching guardrail structure 16 to prevent the pressing portion 15 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 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 corresponding pressing portion 15 and the position of the first lock opening 14 compared to the support rod 13 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 Figure 2 , Figure 3 and Figure 4 As shown, the first lock head 24 located on the first notch 23 is also provided with a boss-shaped limiting portion 25 in the axial extension direction (as shown in FIG. Figure 3 As shown, the dotted line frame portion almost clearly identifies the limit portion 25 in the example scene of the attached figure); matched, located on the male end connector 1, and having a first lock 14 on the cross bar made of a long concave groove 17; through Figure 2 and Figure 4Through observation, it can be seen that in the preferred embodiment, the extension length of the long concave groove 17 directly extends from the end of the cross bar near the docking port to the area near the support rod 13, covering the position of the first lock 14; such a configuration not only completes the adjustment of the moment balance between the cross bar where the first lock 14 is located and the cross bar owned by the pressing portion 15 compared with the support rod 13, but more importantly, the long concave groove 17 is used when the first lock head 24 is locked with the first lock 14. The long concave groove 17 is sleeved on the limiting portion 25, so that the locking state between the first lock head 24 and the first lock 14 can achieve a better stability under the auxiliary restriction of the long concave groove 17 and the limiting portion 25. At this time, even if there is an external vibration object that can break through Figure 2 When the middle fence structure 26 hits the crossbar in the first slot 23 , the impact force can be effectively offset based on the long concave slot 17 being sleeved on the limiting portion 25 structure without causing changes in the locking stability of the first lock head 24 and the first lock slot 14 .

[0075] 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 Figure 5 and Figure 6 As shown, the first notch 23 is provided with a first notch 231 (at the end of the female connector 2) near the connecting end of the female connector 2. Figure 5 The first notch 231 is marked with a dotted frame), the width d1 of the first notch 231 just accommodates the width d2 of the support rod 13, and the length L1 of the first notch 231 satisfies the required distance of the support rod 13 from the connecting end face of the female connector 2 in the axial direction after the male connector 1 and the female connector 2 are connected. Figure 7 The figure shows a cross-sectional view of the corresponding male-end connector 1 and the female-end connector 2 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 13. 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. 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).

[0076] Dustproof, waterproof, and shockproof are the three major problem factors described in the background technology of the present invention. The most core shockproof problem has been specifically solved in the above-mentioned 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, dustproof and waterproof, as the other two problem factors, cannot be effectively achieved by relying on 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 make up for the dustproof and waterproof of the remaining two problem factors mentioned above. In combination Figure 2 ,like Figure 8 and Fig. 9 As shown, a ring groove 18 is provided in the housing area between the connecting end surface of the male connector 1 and the support rod 13; Fig. 9 As shown, the ring groove 18 is used to enclose one or more waterproof rubber rings 3 (in Fig. 9 It is only shown in the form of a waterproof rubber ring 3, 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 3 can also be used. For example, two or three waterproof rubber rings 3 with circular cross-sections can be directly used to achieve the waterproof effect.). In the specific implementation process, considering that the first notch 231 is fully utilized as the first stage of the waterproof rubber ring 3 entering the female connector 2 during the connection process, the thinning area of ​​the first notch 23 is used as the second stage of the waterproof rubber ring 3 entering the female connector 2 during the connection process, thereby ensuring that the corresponding installed waterproof rubber ring 3 can be connected with the male connector 1 and the female connector 2. In the case of almost no additional damping brought by the waterproof rubber ring 3, the connection process is completed to achieve the locking of the first lock head 24 and the first lock port 14. In addition to the technical features of the first notch 231 and the features of the first notch 23, the above-mentioned effect also needs to have the following features to ensure the two-stage setting for the waterproof rubber ring 3 to reach the preset waterproof position. That is, after the male connector 1 and the female connector 2 are connected, the inner surface of the housing where the annular groove 18 abuts against the female connector 2 is opposite to the outer surface of the female connector 2 where the first notch 23 is located. Fig. 9 shown.

[0077] 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.

[0078] The reason why it is described as a waterproof structure that can interact with the above-mentioned locking structure is also explained by Fig. 9 to explain. Fig. 9 In the cross-sectional view after the connection is completed, it can be seen that the inner wall position of the female end connector 2 abutted by the corresponding waterproof rubber ring 3 is exactly located at the connection between the first lock head 24 and the limiting portion 25. In this way, the waterproof rubber ring 3 will have a certain lifting effect on the first lock head 24, thereby enhancing the locking effect between the first lock head 24 and the first lock port 14.

[0079] like Fig.10 and Fig.11 As shown, the male connector 1 is provided with a female port 19 at its connecting end, wherein the first ceramic abutment 11 is located at the central axis of the female port 19. Fig.11 The center position of the central axis of the female port 19 is occupied by the first ceramic abutment 11, so that a structure is formed in which the outer wall of the female port 19 is formed by the shell of the male connector 1, and the center of the female port 19 is filled by the first ceramic abutment 11, and the remaining space of the female port 19 forms an annular cavity; Fig.12 As shown, the female connector 2 is provided with a male port 27 with a hollow structure in the middle axis (it should be noted that Fig.12 Only the key area from the male port 27 is marked, and it can also be understood as extending from the male port 27 to Fig.12 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 21 is located in the hollow structure of the male port 27. Here, it is necessary to supplement Figure 1 The second ceramic abutment 21 in the figure is actually the metal ring that the second ceramic abutment 21 is sleeved with, and the corresponding first ceramic abutment 11 will also be inserted into the corresponding metal ring after the connection is completed. Figure 1 The reason is that the male connector 1 and the female connector 2 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 11 and the second ceramic abutment 21 (the corresponding metal ring can also be added by the back Fig.16 The exploded diagram shown is intuitive).

[0080] like Fig.13 As shown, after the male connector 1 and the female connector 2 are connected, the male port 27 and the female port 19 are connected synchronously, and the first ceramic abutment joint 11 and the second ceramic abutment joint 21 are connected simultaneously. Fig.13In the figure, 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. 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. Fig.13 In the embodiment, the first ceramic abutment joint 11 and the second ceramic abutment 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.

[0081] In order to realize that the male connector 1 and the female connector 2 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 1 is provided with one or more foolproof protrusions 28 (such as Fig.11 The inner wall of the female connector 2 is provided with one or more foolproof grooves 29 (such as the foolproof protrusion 28 on the surface of the shell) that match the foolproof protrusion 28. Fig.12 As shown); wherein, when there are multiple specifications of male end connectors 1 and female end connectors 2, the positions and quantities of the corresponding fool-proof protrusions 28 and fool-proof grooves 29 ensure that male end connectors 1 and female end connectors 2 from different specifications cannot be connected.

[0082] Specific optional locations for the fool-proof protrusions 28 and fool-proof grooves 29 include: in the first mode, a preset number of fool-proof protrusions 28 are provided at a preset position between the annular groove 18 and the connecting end face of the male connector 1. In the second mode, a preset number of fool-proof protrusions 28 are provided at a preset position between the annular groove 18 and the tail end of the male connector 1; wherein the fool-proof grooves 29 are provided to match the fool-proof protrusions 28. Through practice, it has been verified that among the above two modes, the second mode 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 mode), and the first mode requires that the corresponding fool-proof 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-proof grooves 29 will become a potential area for generating gaps.

[0083] In the implementation process of the embodiment of the present invention, a variety of optional forms are also provided for the pressing portion 15 to meet different unlocking methods.

[0084] like Fig.14As shown in the first form: the pressing portion 15 is formed by folding the cross bar located at the corresponding side of the support rod 13 according to a preset shape; wherein the preset shape includes a bevel 151 connected to the cross bar where the first lock 14 is located, and a cross side 152 connected to the bevel 151. Fig.14 a shows the effect of the male connector 1 and the female connector 2 being stably connected and loaded. Fig.14 b is a schematic diagram showing the effect of applying a vertical downward pressure to the horizontal side 152 of the pressing portion 15, so that the horizontal bar including the first lock 14 on the other side of the support rod 13 is lifted up based on the lever principle, thereby unlocking the first lock 14 and the first lock head 24. Fig.14 As shown, the first lock head 24 is in a flat half-arrow shape with only one side of the arrow wing 241 retained.

[0085] like Fig.15 As shown, the second form: the preset shape is formed by the cross bar located on the corresponding side of the support rod 13 being shaped into a semicircular arc.

[0086] 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 13 located on both sides of the support rod constitute a seesaw to complete the locking and unlocking between the first lock head 24 and the first lock port 14.

[0087] 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.

[0088] In order to more effectively utilize the characteristics of the unlocking action process brought by the second form, it is preferred that Fig.15 As shown in FIG. 2 , the first lock head 24 is a flat half-arrow shape with only one side of the arrow wing 241 retained, wherein the half-arrow shape has a preset width d3, and a locking protrusion 242 is made at the end of the arrow wing 241 for locking the first lock port 14, and the locking protrusion 242 is used to limit the shaking of the surface of the cross bar around the first lock port 14 after the first lock head 24 and the first lock port 14 are locked. Fig.14 The structure of Fig.15 The semicircular arc structure described above must be used in order to better undertake the following Fig.15 b pushes leftward horizontally, so that the first locking port 24 is decoupled from the locking protrusion 242, and then the first locking port 24 is connected in a continuous manner. Fig.15 c's horizontal leftward thrust and vertical downward thrust from 15b (similar to Fig.14b) together form an oblique downward force, causing the first lock opening 24 to disengage from the first lock head 14.

[0089] At this point, you can go back to the previous Figure 7 As shown, it is a cross-sectional view of the male connector 1 and the female connector 2 after the connection is completed, wherein the length L1 is made to have a surplus space L2 compared to the distance space deep into the support rod 13. A little more surplus space can also ensure that the corresponding support rod 13 can adaptably withstand the load during the locking and unlocking process. Fig.15 b The deformation space shown.

[0090] Embodiment 2:

[0091] As a complete solution of Example 1 of the present invention, it further considers the better implementation scheme in the optoelectronic mixing 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 same connector structure, focusing on the optoelectronic mixing perspective.

[0092] 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 1 of the present invention, wherein the same structural name or similar structural components are used. Those skilled in the art can 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 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.

[0093] Embodiment 2 of the present invention provides a shockproof optoelectronic hybrid connector, such as Figure 16-Figure 22 As shown, it includes a male connector 4 and a female connector 5 (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). Next, the relevant structures will be specifically described in combination with various drawings, including:

[0094] The male connector 4 is composed of a first outer shell 41, a first plug assembly 42, a middle shaft assembly 43 and a first tail sleeve 44 which are connected to each other; Fig.17 , Fig.18 and Fig.19As shown, a rectangular boss 431 is made on at least one horizontal surface of the central axis component 43, and 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 component 43, and are embedded in the accommodating cavity 412 in the first outer shell 41 after the first outer shell 41 and the central axis component 43 are assembled; Fig.19a As shown, 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 .

[0095] The female connector 5 is composed of a second outer shell 51, a second plug assembly 52, a power transmission assembly 53 and a second tail sleeve 54 which are connected to each other; Fig. 20 As shown, the power transmission component 53 includes a columnar body 531 connected to the second plug core component 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 through hole 511 on the inner wall of the second outer shell 51, as shown in FIG. Fig.21 The figure shows a cross-sectional view of the guide through hole 511 on the inner wall of the second outer shell 51 before the fork of the fork-shaped electrical terminal 533 passes through. Fig. 22 It is a cross-sectional view of the complete assembly of the fork head of the fork-shaped electrical terminal 533 passing through the guide through hole 511 on the inner wall of the second outer shell 51 .

[0096] When the male connector 4 and the female connector 5 are connected, the first plug assembly 42 is docked with the second plug assembly 52, and the contacts on both sides of the fork head of the fork-shaped electrical terminal 533 are respectively abutted against the two side posts 452 of the door-shaped electrical terminal 45.

[0097] 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.

[0098] like Fig.17As described above, the rectangular boss 431 on the corresponding central axis component 43 is only shown to be set on one side. In the specific trial scheme, the difference between setting the rectangular boss 431 on one side or setting the rectangular boss 431 on both sides is the difference in the number of corresponding door-type electrical terminals 45 that can be arranged, that is, the rectangular boss 431 can be selectively set on one side or two rectangular bosses 431 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 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 corresponding horizontal plane close to the door beam 453 where the door-type electrical terminal 45 is fixed, which is used to limit the door beam 453, and, with reference to Fig.17 and Fig.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 optimal.

[0099] In the process of implementing the embodiment of the present invention, in order to achieve a better dustproof effect, the corresponding first tail sleeve 44 is preferably formed by casting. The biggest advantage of this is that the gaps between components can be filled by the casting process, achieving a better dustproof effect. At this time, the limit protrusion 432 proposed in the above improved solution can be further reused in the current solution of implementing the first tail sleeve 44 by casting. In addition, further Fig.17 As shown, one or more anti-pull protrusions 433 are symmetrically arranged on the left and right sides of the central shaft assembly 43, and the one or more anti-pull protrusions 433 act together with the limiting protrusions 432 on the first tail sleeve 44 formed by casting, forming a locking mechanism for the first tail sleeve 44 against pulling in four directions: up, down, left, and right. In this way, no matter in which direction the first tail sleeve 44 is bent and pulled, the matching area has the limiting protrusions 432 and / or the anti-pull protrusions 433 as objects to limit the first tail sleeve 44 from being separated from the original assembly position and play a corresponding pulling role.

[0100] like Fig.23 , Fig.23a and Figure 23b As shown, a channel 434 is provided in the middle of the limiting protrusion 432 on each horizontal plane for passing the wire 63; wherein the height of the limiting protrusion 432 is consistent with the surface height h of the wire 6 passing through the channel 434; and the width d6 of the channel 434 is less than the preset value of the diameter width d7 of the wire 6. Fig.23cOnce the welding between the wire end of wire 63 and the door beam 453 is completed, the corresponding welding area and the connection area between the wire end and the wire 6 protective cover will have the same effect as the anti-pull protrusion 433, and then after being combined with the limiting protrusion 432, it will form the same effect as the multi-point anti-pull protrusion 433.

[0101] In order to achieve the docking effect of the plug 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 plug assemblies. Therefore, there is another possible implementation in combination with the embodiment of the present invention, such as Fig.23 and Fig.24 As shown, the male end connector 4 also includes a spring 46, and one side of the limit block 421 on the first plug assembly 42 abuts against the spring 46 limit groove of the central axis assembly 43 through the spring 46; the other side of the limit block 421 directly abuts against the preset plug guide groove 411 on the first shell 11.

[0102] like Fig.25 As shown, the two outer walls 1121 of the accommodating cavity 412 are respectively formed by the outer shell corner contours of the first outer shell 41, and the remaining outer wall 1122 of the accommodating cavity 412 is formed by the inner wall pattern behind the female port, and the last side 1123 of the accommodating cavity 412 is directly interconnected with the female port space; wherein, the last side is a reserved channel for the fork-type electrical terminal 533 to enter and complete electrical interconnection with the door-type electrical terminal 45. Fig.25 The corresponding position area of ​​the mother port is marked with semi-transparent shadow.

[0103] like Fig.25 As shown, in the preferred implementation, a semicircular groove is made on the inner wall pattern in the same direction as the accommodating cavity 412. The semicircular groove is made, on the one hand, to provide an air flow groove to assist the heat dissipation on the door column 452 of the door-type electrical terminal 45, and on the other hand, to reduce the corresponding friction during the insertion of the door column 452 of the door-type electrical terminal 45, making the installation process more convenient.

[0104] After focusing on the possible details of implementing the expansion scheme for the male end connector 4 above, starting from the female end connector 5, the improvement ideas that may be introduced in the implementation scheme of the embodiment of the present invention, and their supporting principles and original intentions will be fully explained.

[0105] like Fig. 20 As shown in FIG. 1 , a preferred structural implementation of the positioning member 532 provided in an embodiment of the present invention is shown. Fig. 20 At the time, it is only a schematic supporting structure display of the power transmission component 53, and there is no Fig. 20Therefore, as a preferred implementation scheme, the structure for embedding the fork-shaped electrical terminal 533 on the positioning member 532 includes a rectangular groove 5321 provided on the positioning member 532, and a skylight 5322 is formed in a section of the rectangular groove 5321 away from the fork head to provide a welding area for the wire 6 and the fork-shaped electrical terminal 533.

[0106] Furthermore, the provision of the skylight 5322 retains the shell portion of the positioning member 532 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 when the male end connector 4 and the female end connector 5 are connected.

[0107] In order to further adapt to the above considerations of digestive resistance, Fig.26 As shown, the fork-type electrical terminal 533 is made into a Z shape, wherein the upper horizontal portion is embedded in the positioning member 532, and the lower horizontal portion of the fork-type electrical terminal 533 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 533 and the door-type electrical terminal 45 when the male-end connector 4 and the female-end connector 5 are connected.

[0108] 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.

[0109] 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.
