Abstract
Description
Technical Field
[0001] This utility model belongs to the field of connector technology, specifically relating to an integrated electrical interconnection device that realizes self-floating docking function. Background Technology
[0002] Traditional inter-compartment electrical connections involve redundant cable lengths before compartment docking. Both compartments must have structurally designed space for manual connector mating. After mating, the cable is embedded within the compartment before the two compartments are connected. Because the cable is long and lacks fixed points, the cable harness is unrestrained in the free space of the compartment, leading to electrical short circuits due to wear between the harness and the compartment walls. The extra cable also occupies space within the compartment, resulting in wasted space. Therefore, traditional inter-compartment electrical connections are inefficient due to manual operation, have poor product repairability, low reliability, and are not conducive to automated assembly. The implementation effect of existing technical solutions is as follows: Figures 1-4 As shown, the system includes a left compartment and a right compartment. Before the electrical interfaces of the compartments are connected, one end of the cable in the left compartment is connected inside the left compartment, and the other end extends out of the left compartment. The extended end is connected to a plug connector, so that the electrical interface and the cable extend outside the compartment. The right compartment has a socket connector at the mating end. When the electrical interfaces of the compartments are connected, the plug connector and the socket connector are manually operated to achieve the electrical interface mating. Then the cable is pre-embedded in the compartment and the left and right compartments are connected. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an integrated electrical interconnection device that realizes self-floating docking function.
[0004] The objective of this utility model is achieved through the following technical solution. The integrated electrical interconnection device for achieving self-floating docking functionality, according to this utility model, includes at least two docking compartment components. Each compartment component includes a compartment shell and a connector disposed within the compartment shell. In two adjacent compartment components, one compartment component has a guide post at its mating end of the compartment shell, and the other compartment component has a guide groove at its mating end for mating with the guide post during docking. The connector within the compartment shell of one of the adjacent compartment components is a fixed plug connector, and the connector within the compartment shell of the other compartment component is a floating socket connector for mating with the fixed plug connector. The floating direction of the floating socket connector is radial. One of the fixed plug connector and the floating socket connector is provided with a guide pin, and the other is provided with a guide hole for engaging with the guide pin. Before the fixed plug connector and the floating socket connector float and mate, the guide post is inserted into the guide groove.
[0005] Furthermore, at least two guide posts are distributed circumferentially on the outer wall of the interlocking end of the cabin shell of one of the cabin components, and at least two guide grooves are distributed circumferentially on the inner wall of the interlocking end of the cabin shell of the other adjacent cabin component. After the two cabin components are interlocked, the guide posts are inserted and nested in the guide grooves.
[0006] Furthermore, a connector mounting panel is provided inside the housing of the floating socket connector. The floating socket connector includes a socket connector housing with a through hole. The floating connector mounting screw passes through the through hole and is screwed into the threaded hole of the connector mounting panel. There is a floating gap between the floating connector mounting screw and the through hole on the socket connector housing.
[0007] Furthermore, the cabin component has detachably installed electrical components inside its cabin shell. The electrical components include a bracket detachably installed inside the cabin shell and at least two electronic modules detachably installed inside the bracket. The electronic modules are electrically connected to each other and are electrically connected to a fixed plug connector and / or a floating socket connector.
[0008] Furthermore, the electrical components include a left electronic component and a right electronic component that are connected to each other. The left electronic component includes a left bracket and at least two electronic modules that are detachably mounted on the left bracket. Each electronic module is provided with a plug connector. The right electronic component includes a right bracket, an electrical interconnection assembly that is detachably mounted on the right bracket, and an electronic module IV that is detachably mounted on the right bracket. The electronic module IV is electrically connected to the electrical interconnection assembly. The electrical interconnection assembly includes a rigid-flex PCB board. The rigid-flex PCB board is provided with a socket connector for mating with the plug connector on the electronic module. The rigid-flex PCB board is electrically connected to a fixed plug connector and / or a floating socket connector.
[0009] Furthermore, at least two electronic modules are stacked sequentially inside the cavity of the left bracket, and a rigid-flex PCB board and electronic module IV are stacked sequentially inside the cavity of the right bracket.
[0010] Furthermore, one of the adjacent cabin components has an observation hole on the interlocking end wall for observing whether the adjacent cabin components are properly interlocked, and the other cabin component has a circumferential groove on the interlocking end outer wall. When the adjacent cabin components are docked, the adjacent cabin components are properly docked when the circumferential groove is aligned with the observation hole.
[0011] Furthermore, after the adjacent cabin components are docked in place, wedge blocks are forcibly installed in the observation holes and corresponding circumferential grooves.
[0012] Furthermore, it includes a forward cabin component, a middle cabin component, and a rear cabin component that are connected in sequence. Electrical components are detachably installed in the middle cabin component, and floating socket connectors are installed on both sides of the electronic components. Fixed plug connectors for interlocking with the floating socket connectors are installed in both the forward cabin component and the rear cabin component.
[0013] Furthermore, the insertion ends of the guide pin and guide hole are both chamfered.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] Blind-plug floating docking is possible between modules. Guided by guide posts and guide slots, each module is ensured to align correctly. The socket connectors are floatingly positioned within the mid-section hull. When there is a misalignment between the plug and socket connectors, the radial floating of the socket connectors allows for docking without mechanical damage. This eliminates manual operation for electrical connections, avoiding the wire slippage and wear problems caused by excessively long cables in traditional manual docking. It improves the operability and maintainability of module docking, meets the requirements of rapid assembly, and achieves "standardization, modularization, and universalization," providing a guarantee for automated module assembly and platform incubation. Furthermore, with the plug and socket connectors pre-positioned within their respective modules, there is no need to reserve cable lengths. After docking, the cables will not wobble, preventing cable damage and not occupying additional space within the module.
[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0071] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0072] This utility model discloses an integrated electrical interconnection device for achieving self-floating docking function, as shown in Embodiment 1. Figures 5 to 17-1 As shown, hereinafter referred to as the device.
[0073] The device includes a forward cabin component 6, a mid-cabin component 7, and a rear cabin component 8, as detailed below. Figure 5 , Figure 6 The three compartment components are structurally installed and electrically connected through mechanical docking structures and electrical connection assemblies, such as... Figure 7 , Figure 8 As shown. The front cabin component 6 includes a front cabin shell 63, the middle cabin component 7 includes a middle cabin shell 76, and the rear cabin component 8 includes a rear cabin shell 84. In this embodiment, the front cabin shell 63, the middle cabin shell 76, and the rear cabin shell 84 are all hollow cylindrical shells with the same outer diameter.
[0074] During the axial mechanical docking installation of the three compartment components, the insertion is guided by guide grooves and guide columns (e.g., Figure 9-2 , Figure 10-2 , Figure 10-3 , Figure 11-2 (As shown).
[0075] The outer circumference of the mating end of the forward cabin hull 63 and the middle cabin hull 76 is provided with a circumferential groove I61, and multiple guide posts I66 are distributed circumferentially on the outer wall of the mating end of the forward cabin hull 63. In this embodiment, the guide posts I66 are closer to the mating end face than the circumferential groove I61, which facilitates timely guidance of the mating. Correspondingly, multiple guide grooves I710 are distributed circumferentially on the inner wall of the mating end of the middle cabin hull 76 and the forward cabin hull 63, and the guide grooves I710 extend rearward from the mating end face of the middle cabin hull 76. The guide posts I66 and guide grooves I710 correspond one-to-one. When the forward cabin hull 63 and the middle cabin hull 76 are mated, the guide posts I66 are inserted into the corresponding guide grooves 710 to ensure accurate mating position in the circumferential direction.
[0076] The interlocking ends of the middle cabin hull 76 and the aft cabin hull 84 are provided with circumferential grooves II 73 on their outer circumference, and multiple guide posts II 711 are distributed circumferentially on the outer wall of the interlocking end of the middle cabin hull 76. In this embodiment, the guide posts II 711 are closer to the interlocking end face than the circumferential grooves II 73. Correspondingly, multiple guide grooves II 88 are distributed circumferentially on the inner wall of the interlocking end of the aft cabin hull 84 and the middle cabin hull 76. The guide grooves I 710 extend rearward from the interlocking end face of the aft cabin hull 84. The guide posts II 711 and guide grooves II 88 correspond one-to-one. When the middle cabin hull 76 and the aft cabin hull 84 are interlocked, the guide posts II 711 are inserted into the corresponding guide grooves II 88 to ensure accurate interlocking position in the circumferential direction.
[0077] Whether the three-compartment components are properly fitted is determined by observing through evenly distributed circumferential observation holes (e.g., Figure 6 As shown), the observation holes and corresponding circumferential grooves on the three-compartment hull are structurally installed and fixed between the three compartments by wedge blocks. Figure 6 , Figure 7 (As shown).
[0078] Multiple observation holes I71 are distributed circumferentially on the walls of the mating ends of the middle cabin shell 76 and the front cabin shell 63. After the middle cabin shell 76 and the front cabin shell 63 are mated in place, the circumferential groove I61 is aligned with the observation hole I71. The circumferential groove I61 can be seen through the observation hole I71. During the mating process, the circumferential groove I61 is observed through the observation hole I71. When the two side walls of the circumferential groove I61 are aligned with the inner wall corresponding to the observation hole I71, it indicates that the mating is in place. At this time, wedge blocks are simultaneously forcibly installed in the observation hole I71 and the circumferential groove I61 to fix the middle cabin shell 76 and the front cabin shell 63.
[0079] Multiple observation holes II81 are distributed circumferentially on the walls of the mating ends of the aft and middle cabin shells 84 and 76. When the aft and middle cabin shells 84 and 76 are mated in place, the circumferential groove II73 is aligned with the observation holes II81. The circumferential groove II73 can be seen through the observation holes II81. During the mating process, the circumferential groove II73 is observed through the observation holes II81. When the two side walls of the circumferential groove II73 are aligned with the inner walls corresponding to the observation holes II81, it indicates that the mating is in place. At this time, wedge blocks are simultaneously forcibly installed in the observation holes II81 and the circumferential groove II73 to fix the aft and middle cabin shells 76.
[0080] The upper and lower walls of the mid-hull 76, and the upper and lower parts of the internal electrical components 77, are each provided with four symmetrically distributed electrical component screw mounting holes (e.g., ...). Figure 6 , Figure 8 As shown, the electrical component screw mounting holes I 72 on the mid-hull shell 76 and the electrical component screw mounting holes II 74 on the electrical component 77 correspond to each other after the electrical component 77 is correctly installed. After the electrical component 77 is installed into the mid-hull shell 76 from the left end, screws are passed through the electrical component screw mounting holes I 72 and screwed into the electrical component screw mounting holes II 74. The mid-hull shell 76 and the electrical component 77 are fixed by eight screws symmetrically placed on the top and bottom, thus achieving the integrity of the structure in terms of reliability.
[0081] Forward cabin component 6 includes forward cabin shell 63 and fixed plug connector A62, such as Figure 9 As shown, the fixed plug connector A62 is mounted inside the front cabin housing 63 via its own panel. The panel is fixed to the front cabin housing 63 by two symmetrically distributed screws at an angle, as shown. Figure 9-1 As shown in the enlarged view, a fixed connector mounting hole A65 is provided on the panel. A screw is passed through the fixed connector mounting hole A65 and screwed into the threaded hole on the forward cabin shell 63 to fix the fixed plug connector A62. The fixed plug connector A62 has obliquely symmetrically distributed guide pins A64, which are used to guide the insertion of the floating socket connector A75 on the mid-cabin component 7. Before the connectors A (including the fixed plug connector A62 and the floating socket connector A75) are inserted, the guide posts I66 provided on the forward cabin shell 63 guide the forward cabin component 6 and the mid-cabin component 7 to correctly insert, ensuring the correct insertion of the subsequent connectors A. In this embodiment, four guide posts I66 are evenly distributed circumferentially on the forward cabin shell 63 for guiding the insertion between the forward cabin component 6 and the mid-cabin component 7.
[0082] Aft cabin component 8 includes aft cabin shell 84, fixed plug connector B82, and fixed plug connector C83, such as Figure 11As shown, fixed plug connectors B82 and C83 are mounted on the same panel. They are installed inside the rear hatch housing 84 via the panel. Fixed connector mounting screws C86 pass through the through-holes in the panel and are screwed into the threaded holes in the rear hatch housing 84, thus fixing the panel to the rear hatch housing 84. Two fixed connector mounting screws C86 are symmetrically distributed at both ends of the panel. Figure 11-1 As shown. Fixed plug connector B82 has guide pins B85 symmetrically arranged at both ends, and fixed plug connector C83 has guide pins C87 symmetrically arranged at both ends. These two connectors use their own guide pins to guide the mating of corresponding floating socket connectors (including floating socket connectors B78 and C79) on the mid-cabin component 7. In this embodiment, four guide grooves II88 are evenly distributed circumferentially on the aft cabin shell 84. Before the mating of connectors B (including fixed plug connector B82 and floating socket connector B78) and C (fixed plug connector C83 and floating socket connector C79), the guide grooves II88 on the aft cabin shell 84 are correctly mated with the mid-cabin component 7 to ensure the correct mating of subsequent connectors A and B.
[0083] Mid-cabin component 7 comprises mid-cabin shell 76 and electrical components 77, such as... Figure 10 As shown, a floating socket connector A75 is installed at the front end of the electrical component 77 for electrical connection with the fixed plug connector A62 of the forward cabin component 6. Floating socket connectors B78 and C79 are installed at the rear of the electrical component 77 for electrical connection with the fixed plug connectors B82 and C83 of the aft cabin component 8, respectively. In this embodiment, four guide grooves I710 are evenly distributed circumferentially on the front inner wall of the mid-cabin hull 76, and four guide posts II711 are evenly distributed circumferentially on the rear end of the mid-cabin hull 76, as shown... Figure 10-2 , Figure 10-3 As shown, before connectors A, B, and C are inserted, the pre-insertion between the corresponding guide posts and guide slots plays a coarse guiding role when the middle cabin component 7 is inserted into the front cabin component 6 and the rear cabin component 8 as a whole.
[0084] The electrical components 77 within the mid-cabin component 7 include a left electronic component 724 and a right electronic component 725. The left electronic component 724 and the right electronic component 725 are fixed to the mid-cabin shell 76 by eight circumferential screws, forming a single component. Figure 10 and Figure 15 , Figure 15-1As shown. The left electronic component 724 includes a left bracket 733 and three matching electronic modules (electronic module I 727, electronic module II 728, and electronic module III 729, respectively). Connectors I 730, II 731, and III 732 are respectively mounted on electronic modules I 727, II 728, and III 729. The left bracket 733 has an internal cavity. Each electronic module is sequentially pushed axially into the left bracket 733 and fixed to the left bracket 733 by multiple circumferential screws (e.g., ...). Figure 15-1 , Figure 15-2 , Figure 16-1 , Figure 16-2 As shown, the left bracket 733 is provided with electrical component screw mounting holes II 74. The left electronic component 724 is fixed in the middle cabin shell 76 by screws engaging with the electrical component screw mounting holes II 74.
[0085] The right electronic component 725 includes a right bracket 742, an electrical interconnection assembly 726, and an electronic module IV 743. The electrical interconnection assembly 726 is first pushed in and secured to the right bracket 742 with screws (e.g., ...). Figure 17 and Figure 17-1 (As shown), then push the electronic module IV743 axially into the right bracket 742 and fix it to the right bracket 742 with multiple screws (as shown). Figure 15-1 As shown, the electronic module IV 743 is electrically connected to the electrical interconnection assembly 726. The electrical interconnection assembly 726 includes a rigid-flex PCB board 736, which has PCB board nut mounting holes 737 and mounting nut kits 734. The right bracket 742 has bracket screw mounting holes 738. PCB board mounting screws 735 are passed through the bracket screw mounting holes 738 and screwed into the mounting nut kits 734 to fix the rigid-flex PCB board 736 to the right bracket 742. Socket connector I 739, socket connector II 740, and socket connector III 741 are connected to the rigid-flex PCB board 736. The right bracket 742 has electrical component screw mounting holes II 74. The right electronic component 725 is fixed to the mid-cabin shell 76 by the screw engaging with the electrical component screw mounting holes II 74.
[0086] After docking, the left electronic component 724 and the right electronic component 725 are fixed together as a single electronic compartment component with screws, and simultaneously fixed inside the middle compartment shell 76. Socket connectors I 739, II 740, and III 741 are respectively connected to plug connectors I 730, II 731, and III 732 on the left electronic module, and then locked in place to achieve electrical connection. The rigid-flex PCB board 736 also connects to floating socket connectors A75, B78, and C79. Floating socket connector A75 is mounted on the mounting panel located on the left bracket 733 by screws (see details). Figure 15 ), Floating socket connectors B78 and C79 are mounted on a mounting panel located inside the midship hull 76 via screws.
[0087] The fixed plug connector A62 is provided with a guide pin A64 and a guide chamfer 67. The floating socket connector A75 includes a socket connector housing A717, which has a guide hole A716 for guiding mating with the guide pin A64. A connector mounting panel A718 is provided inside the mid-hull housing 76. The floating connector mounting screw A719 passes through a through hole on the socket connector housing A717 and is screwed into a threaded hole on the connector mounting panel A718. There is a floating gap 10 between the floating connector mounting screw A719 and the through hole on the socket connector housing A717, allowing the floating socket connector A75 to float radially within the mid-hull housing 76 when mating with the fixed plug connector A62. When the connector A is mated, the guide pin A64 first inserts into the guide hole A716. If the connector A has a radial deviation, the floating socket connector A75 floats radially under the guidance of the guide pin A64 and the guide hole A716, aligning itself radially with the fixed plug connector A62 to ensure mating. One of the mating ends of guide pin A64 and guide hole A716 is chamfered, or both are chamfered, so that the mating ends of guide pin A64 and / or guide hole A716 form corresponding tips and flared mouths, so that guide pin A64 and guide hole A716 can be mated within the floating range, and under the action of mating force, floating socket connector A75 floats radially, so that floating socket connector A75 is aligned with fixed plug connector A62.
[0088] A guide pin B85 is provided on the fixed plug connector B82. The floating socket connector B78 includes a socket connector housing B721, which has a guide hole B714 for mating with the guide pin B85. A connector mounting panel B720 is provided inside the mid-hull hull 76. A floating connector mounting screw B712 passes through a through hole on the socket connector housing B721 and is screwed into a threaded hole in the connector mounting panel B720. A floating gap 10 exists between the floating connector mounting screw B720 and the through hole on the socket connector housing B721, allowing the floating socket connector B78 to float radially within the mid-hull hull 76 when mating with the fixed plug connector B82. When connector B is mated, the guide pin B85 first inserts into the guide hole B714. If connector B has a radial deviation, guided by the guide pin B85 and the guide hole B714, the floating socket connector B78 floats radially to align itself radially with the fixed plug connector B82, ensuring mating. One or both of the mating ends of the guide pin B85 and the guide hole B714 are chamfered, so that the mating ends of the guide pin B85 and / or the guide hole B714 form corresponding tips and flared mouths. This allows the guide pin B85 and the guide hole B714 to mate within the floating range. Under the action of the mating force, the floating socket connector B78 floats radially, aligning the floating socket connector B78 with the fixed plug connector B82.
[0089] A guide pin C87 is provided on the fixed plug connector C83, and a plug connector mounting panel C89 is provided inside the aft housing 84. The fixed plug connector C83 is fixed to the plug connector mounting panel C89 by a fixed connector mounting screw C86. The floating socket connector C79 includes a socket connector housing C723, which has a guide hole C715 for mating with the guide pin C87. A connector mounting panel C722 is provided inside the mid-cabin housing 76. A floating connector mounting screw C713 passes through a through hole on the socket connector housing C723 and is screwed into a threaded hole in the connector mounting panel C722. There is a floating gap 10 between the floating connector mounting screw C713 and the through hole on the socket connector housing C723, allowing the floating socket connector C79 to float radially within the mid-cabin housing 76 when mating with the fixed plug connector C82. When connector C is mated, guide pin C87 first inserts into guide hole C715. If connector C has a radial deviation, guided by guide pin C87 and guide hole C715, floating socket connector C79 floats radially to align with fixed plug connector C82 radially, ensuring mating. One or both of the mating ends of guide pin C87 and guide hole C715 are chamfered, forming corresponding tips and flared openings. This allows guide pin C87 and guide hole C715 to mate within a floating range, and under the action of mating force, floating socket connector C79 floats radially to align with fixed plug connector C83.
[0090] The process of realizing the interlocking and floating function between the front cabin component 6, the middle cabin component 7, and the rear cabin component 8 is described as follows:
[0091] Step 1: Coarse guidance between the forward compartment component 6, the middle compartment component 7, and the aft compartment component 8. Corresponding guide grooves and guide posts are designed on the circumference of each of the forward compartment component 6, the middle compartment component 7, and the aft compartment component 8, such as... Figure 9-2 , Figure 10-2 , Figure 10-3 , Figure 11-2 As shown, the docking of the compartments is controlled by a hole-shaft fit (the mating end of the front compartment component 6 is inserted into the front mating end of the middle compartment component 7, and the rear mating end of the middle compartment component 7 is inserted into the mating end of the rear compartment component 8) to control radial accuracy. Rotating each compartment aligns the guide grooves and guide posts, thereby controlling circumferential angular accuracy. During axial docking between compartments, the fit between the guide posts and guide holes, as well as the hole-shaft fit, prevents axial and radial pitch and sway between the compartments. During the three-compartment docking process, each shell is first guided into place. At this time, the front and rear connectors have not yet made physical contact, which effectively avoids mechanical damage caused by the impact force of the compartment docking acting on the connectors. Figure 12As shown, before the connectors of each compartment are inserted, the guide slots and guide posts guide each other to ensure that each compartment is inserted in the correct orientation. Figure 12-1 The diagram shown is a schematic of connector A before it is inserted. Figure 12-2 The diagram shown is a schematic of connectors B and C before they are mated. When the guide groove and guide post guide each other, there is a contact gap 9 between the plug and socket of each connector.
[0092] Step Two: Precision Guiding Between Connectors: As the three-compartment components are guided step-by-step through the housing, the guide pins and guide holes of the connectors on the three-compartment components begin to contact and guide, such as... Figure 13 As shown, as the guiding depth gradually increases, the guide pin will cooperate with the guide hole, causing the floating socket connector to move radially relative to the middle compartment housing 76. At this time, there is over-positioning between the three compartment housing parts and between the connectors. In order to eliminate this over-positioning, a floating structure is adopted in the mating structure between the floating socket connector and the middle compartment housing 76 to achieve clearance fit between them. This eliminates the fit tolerance of the middle compartment housing 76 and the connector during the mating process, thereby realizing the transition from coarse guidance of the housing fit to precise guidance between the connector guide pin and the guide hole, and realizing the floating docking function between the three compartments in terms of structure.
[0093] During the docking of the three modules, the modules are first rigidly guided into place. After the modules have been inserted to a certain distance, the plugs and sockets of connectors A, B, and C on each module are guided into contact through their respective guide pins and guide holes (e.g., ...). Figure 14-1A , Figure 14-1B , Figure 14-2A , Figure 14-2B , Figure 14-3A , Figure 14-3B The process guides the plug and socket connector housings to mate until the electrical contacts make contact. Without flexible guidance during the mating process, over-positioning of multiple structures can occur, easily causing mechanical damage to the connectors. To avoid this, this invention adds floating connector mounting screws to the socket connector and its corresponding mounting panel. Each floating connector mounting screw has a floating gap of 10 with the socket connector, allowing for 360° free floating within a certain size range between the socket connector and the mounting panel. This action eliminates the possibility of the plug and socket connectors seizing during mating, effectively preventing mechanical damage to the connecting devices during mechanical docking of the left and right compartments, and achieving precise floating guidance and positioning between the electronic compartments.
[0094] The beneficial effects of this utility model are summarized as follows:
[0095] 1. Blind-plug floating docking is possible between compartments. Guided by guide columns and guide slots, each compartment is ensured to align correctly. The socket connectors are floatingly positioned within the mid-hull 76. When there is a misalignment between the plug and socket connectors, the radial floating of the socket connectors allows for docking without mechanical damage. This eliminates manual operation for electrical connections, avoiding the wire slippage and wear problems caused by excessively long cables in traditional manual docking. It improves the operability and maintainability of compartment docking, meets the requirements of rapid assembly, and achieves "standardization, modularization, and universalization," providing a guarantee for automated compartment assembly and platform incubation. Furthermore, the plug and socket connectors are pre-positioned within the corresponding compartments, eliminating the need for pre-reserved cable lengths. After docking, the cables will not wobble, preventing cable damage and saving additional space within the compartment.
[0096] 2. By adopting integrated interconnection technology, electronic modules are stacked and set in corresponding brackets (including left bracket 733 and right bracket 742) to form left electronic component 724 and right electronic component 725. Then, left electronic component 724 and right electronic component 725 are connected and fixed in the middle cabin shell 76. This realizes the miniaturization design and installation of the device into a module. The high integration and axial stacking layout saves the space occupied by traditional distributed equipment installation, solves the dependence of distributed equipment layout on connectors and cables, improves the convenience and operability of module installation, and can remove the screws in the middle cabin shell 76 to remove the left electronic component 724 and right electronic component 725 from the middle cabin shell during disassembly.
[0097] 3. The left electronic component 724 and the right electronic component 725 adopt an integrated rigid-flexible electrical interconnection (mainly achieved through the rigid-flexible PCB board 736). The overall three-dimensional routing path is clear, and the operability and maintainability are strong. It solves the reliability problem of electrical circuit interconnection in narrow spaces, as well as the problems of traditional equipment layout with many customizations, low degree of generalization, weak system integration optimization and poor scalability. It has the advantages of light weight, small size, few parts, high degree of integration and strong scalability.
