Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and particularly relates to an integrated electrical interconnection device that realizes the function of self-floating docking. Background Art

[0002] The traditional electrical connection method between cabin segments is to make the cable length redundant before the cabin segments are docked. The two ends of the cabin segments should reserve space in the structure to enable manual insertion operation of the connector. After the connector is inserted, the cable should be embedded in the cabin segment, and then the two ends of the cabin segments are docked in place. Since the cable is long and has no fixed points, the wire harness will be in an unconstrained state in the free space of the cabin segment, which will cause electrical short-circuit faults due to wear between the wire harness and the cabin wall in actual use. This extra section of cable will also occupy a certain space in the cabin, resulting in space waste. Therefore, the traditional electrical connection method between cabin segments has low manual operation efficiency, poor product reparability, low reliability in use, and is not convenient for automatic assembly of products. The implementation effect of the prior art solution is as Figures 1 to 4 shown, including a left cabin segment and a right cabin segment. Before the electrical interfaces of the cabin segments are docked, one end of the cable in the left cabin segment is connected inside the left cabin segment, and the other end extends out of the left cabin segment. The extended end is connected to a plug connector, so that the electrical interface and the cable extend out of the cabin. The mating end of the right cabin segment is provided with a socket connector; when the electrical interfaces of the cabin segments are docked, manually operate the plug connector to be inserted into the socket connector to achieve the docking and insertion of the electrical interfaces; then embed the cable in the cabin segment and dock the left and right cabin segments. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an integrated electrical interconnection device that realizes the function of self-floating docking.

[0004] The purpose of the present invention is achieved by adopting the following technical solutions. The integrated electrical interconnection device that realizes the function of self-floating docking according to the present invention includes at least two docked cabin components. The cabin component includes a cabin housing and a connector disposed inside the cabin housing. In two adjacent cabin components, a guiding column is disposed at the docking end of the cabin housing of one of the cabin components, and a guiding groove for insertion and matching with the guiding column is disposed at the docking end of the cabin housing of the other cabin component when the cabin components are docked; the connector inside the cabin housing of one of the two adjacent cabin components is a fixed plug connector, and the connector inside the cabin housing of the other cabin component is a floating socket connector for insertion 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 guiding pin, and the other is provided with a guiding hole for cooperation with the guiding pin; before the fixed plug connector and the floating socket connector are inserted and floated, the guiding column is inserted into the guiding groove.

[0005] Further, at least two guiding columns are circumferentially distributed on the outer wall of the butt-inserting end of the cabin housing of one of the cabin components, and at least two guiding grooves are circumferentially distributed on the inner wall of the butt-inserting end of the cabin housing of another adjacent cabin component. After the two cabin components are butt-inserted, the guiding columns are inserted and nested in the guiding grooves.

[0006] Further, a connector mounting panel is arranged in the cabin housing where the floating socket connector is located. The floating socket connector includes a socket connector housing, and through holes are provided on the socket connector housing. The floating connector mounting screws pass through the through holes and are screwed into the threaded holes of the connector mounting panel. There is a floating gap between the floating connector mounting screws and the through holes on the socket connector housing.

[0007] Further, electrical components are detachably arranged in the cabin housing of the cabin component. The electrical components include a bracket detachably arranged in the cabin housing and at least two electronic modules detachably arranged in the bracket. The electronic modules are electrically connected to each other, and the electronic modules are electrically connected to the fixed plug connector and / or the floating socket connector.

[0008] Further, the electrical components include a left electronic component and a right electronic component that are butt-connected to each other. The left electronic component includes a left bracket and at least two electronic modules detachably arranged on the left bracket. Plug connectors are arranged on the electronic modules; the right electronic component includes a right bracket, an electrical interconnection assembly detachably arranged on the right bracket, and an electronic module IV detachably arranged on the right bracket. The electronic module IV is electrically connected to the electrical interconnection assembly. The electrical interconnection assembly includes a rigid-flexible PCB board, and a socket connector for butt-inserting with the plug connector on the electronic module is arranged on the rigid-flexible PCB board. The rigid-flexible PCB board is electrically connected to the fixed plug connector and / or the floating socket connector.

[0009] Further, at least two electronic modules are stacked in sequence in the cavity of the left bracket, and the rigid-flexible PCB board and the electronic module IV are stacked in sequence in the cavity of the right bracket.

[0010] Further, an observation hole for observing whether the adjacent cabin component is inserted in place is provided on the wall body of the butt-inserting end of the cabin housing of one of the adjacent two cabin components, and a circumferential groove is provided on the outer wall of the butt-inserting end of the cabin housing of the other cabin component. When the adjacent cabin components are docked, when the circumferential groove is aligned with the observation hole, the adjacent cabin components are docked in place.

[0011] Further, after the adjacent cabin components are docked in place, wedge blocks are force-fitted into the observation hole and the corresponding circumferential groove.

The socket connector is floatingly arranged in the middle cabin housing. When there is a deviation in the positions of the plug connector and the socket connector, through the radial floating of the socket connector, mating can be achieved while avoiding mechanical damage to the connectors, realizing the de-manual operation of electrical connection, avoiding the problem of wire movement and wear caused by too long cables during traditional manual docking, improving the operability and maintainability of cabin section docking, meeting the requirements of rapid assembly, and realizing the requirements of "standardization, modularization, and generalization", providing guarantee for the automated assembly and platform incubation of cabin sections. And the plug connector and the socket connector are pre-set in the corresponding cabin sections in advance, without the need to reserve the length of the cable. After docking, the cable will not shake, avoiding cable damage and not occupying additional space inside the cabin section.

[0071] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0072] Embodiment 1 of an integrated electrical interconnection device for realizing self - floating docking function of the present invention, as Figures 5 to 17-1 shown, hereinafter referred to as this device.

[0073] This device includes a front compartment component 6, a middle compartment component 7, and a rear compartment component 8, as detailed in Figure 5 , Figure 6 . The three - compartment components achieve structural installation and electrical connection through a mechanical docking structure and an electrical connection component, as Figure 7 , Figure 8 shown. The front compartment component 6 includes a front compartment housing 63, the middle compartment component 7 includes a middle compartment housing 76, and the rear compartment component 8 includes a rear compartment housing 84. In this embodiment, the front compartment housing 63, the middle compartment housing 76, and the rear compartment housing 84 are all cylindrical housings with the same outer diameter and hollow.

[0074] During the axial mechanical docking installation process between the three - compartment components, insertion and fitting are guided through a guide slot and a guide post (as Figure 9-2 , Figure 10-2 , Figure 10-3 , Figure 11-2 shown).

[0075] The circumferential groove I 61 is provided on the outer circumference of the insertion end of the front cabin housing 63 that mates with the middle cabin housing 76. And a plurality of guide posts I 66 are circumferentially distributed on the outer wall of the insertion end of the front cabin housing 63. In this embodiment, the guide posts I 66 are closer to the insertion end face than the circumferential groove I 61, facilitating the timely guidance of the insertion. Correspondingly, a plurality of guide grooves I 710 are circumferentially distributed on the inner wall of the insertion end of the middle cabin housing 76 that mates with the front cabin housing 63. The guide grooves I 710 extend backward from the insertion end face of the middle cabin housing 76. The guide posts I 66 and the guide grooves I 710 are in one-to-one correspondence. When the front cabin housing 63 and the middle cabin housing 76 are inserted, the guide posts I 66 are inserted into the corresponding guide grooves 710, ensuring accurate circumferential insertion position.

[0076] The circumferential groove II 73 is provided on the outer circumference of the insertion end of the middle cabin housing 76 that mates with the rear cabin housing 84. And a plurality of guide posts II 711 are circumferentially distributed on the outer wall of the insertion end of the middle cabin housing 76. In this embodiment, the guide posts II 711 are closer to the insertion end face than the circumferential groove II 73. Correspondingly, a plurality of guide grooves II 88 are circumferentially distributed on the inner wall of the insertion end of the rear cabin housing 84 that mates with the middle cabin housing 76. The guide grooves I 710 extend backward from the insertion end face of the rear cabin housing 84. The guide posts II711 and the guide grooves II 88 are in one-to-one correspondence. When the middle cabin housing 76 and the rear cabin housing 84 are inserted, the guide posts II 711 are inserted into the corresponding guide grooves II 88, ensuring accurate circumferential insertion position.

[0077] Whether the insertion of the three-cabin components is in place is judged through the observation holes evenly distributed in the circumference (as Figure 6 shown). The observation holes on the three-cabin housings and the corresponding circumferential grooves are fixedly installed between the three cabins in structure through the wedge blocks (as Figure 6 、 Figure 7 shown).

[0078] A plurality of observation holes I 71 are circumferentially distributed on the wall of the insertion end of the middle cabin housing 76 that mates with the front cabin housing 63. After the middle cabin housing 76 and the front cabin housing 63 are inserted in place, the circumferential groove I 61 is aligned with the observation hole I 71. The circumferential groove I 61 can be seen from the observation hole I 71. During the insertion process, the circumferential groove I 61 is observed through the observation hole I 71. When it is observed that the two side walls of the circumferential groove I 61 are aligned with the corresponding inner walls of the observation hole I 71, it indicates that the insertion is in place. At this time, the wedge blocks are simultaneously and forcibly installed in the observation hole I 71 and the circumferential groove I 61 to fix the middle cabin housing 76 and the front cabin housing 63.

[0079] A plurality of observation holes II 81 are circumferentially distributed on the wall body at the insertion end of the rear cabin housing 84 and the middle cabin housing 76. When the rear cabin housing 84 and the middle cabin housing 76 are inserted in place, the circumferential groove II 73 is aligned with the observation hole II 81, and the circumferential groove II 73 can be seen through the observation hole II 81. During the insertion process, the circumferential groove II 73 is observed through the observation hole II 81. When it is observed that the two side walls of the circumferential groove II 73 are aligned with the corresponding inner walls of the observation hole II 81, it indicates that the insertion is in place. At this time, wedge blocks are simultaneously forced into the observation hole II 81 and the circumferential groove II 73 to fix the rear cabin housing 84 and the middle cabin housing 76.

[0080] On the upper and lower wall bodies of the middle cabin housing 76 and the upper and lower parts of the electrical components 77 inside it, there are 4 symmetrically distributed electrical component screw mounting holes (as Figure 6 , Figure 8 shown). The electrical component screw mounting holes I 72 on the middle cabin housing 76 and the electrical component screw mounting holes II 74 on the electrical components 77 correspond to each other after the electrical components 77 are correctly installed. When the electrical components 77 are inserted into the middle cabin housing 76 from the left end of the middle cabin housing 76, screws are used to pass through the electrical component screw mounting holes I 72 and screw into the electrical component screw mounting holes II 74, and the middle cabin housing 76 and the electrical components 77 are fixed by tightening 8 symmetrically distributed screws up and down, achieving the integrity in terms of structural reliability.

[0081] The front cabin component 6 includes a front cabin housing 63 and a fixed plug connector A 62, as Figure 9 shown. The fixed plug connector A 62 is installed inside the front cabin housing 63 through its own panel, and the panel and the front cabin housing 6 are fixed together by 2 screws with an oblique angle symmetric distribution, as Figure 9-1 shown in the enlarged view. Among them, fixed connector mounting holes A 65 are provided on the panel, and screws are passed through the fixed connector mounting holes A 65 and screwed into the threaded holes on the front cabin housing 63 to fix the fixed plug connector A 62. The fixed plug connector A 62 is provided with guide pins A 64 with an oblique angle symmetric distribution for guiding and inserting with the floating socket connector A 75 on the middle cabin component 7. Before the connector A (including the fixed plug connector A 62 and the floating socket connector A 75) is inserted, the front cabin component 6 and the middle cabin component 7 are correctly inserted through the guide post I 66 provided on the front cabin housing 63 to ensure the correct insertion of the subsequent connector A. In this embodiment, four guide posts I 66 are evenly distributed circumferentially on the front cabin housing 63 for guiding and inserting between the front cabin component 6 and the middle cabin component 7.

[0082] The rear cabin component 8 includes a rear cabin housing 84, a fixed plug connector B 82, and a fixed plug connector C 83, as Figure 11As shown, the fixed plug connector B82 and the fixed plug connector C83 are jointly arranged on the same panel. The fixed plug connector B82 and the fixed plug connector C83 are installed in the rear cabin housing 84 through the panel. The fixed connector mounting screw C86 passes through the through hole on the panel and is screwed into the threaded hole of the rear cabin housing 84 to fix the panel to the rear cabin housing 84. Two fixed connector mounting screws C86 are symmetrically distributed at both ends of the panel, as Figure 11-1 shown. Guide pins B85 are symmetrically arranged at both ends of the fixed plug connector B82, and guide pins C87 are symmetrically arranged at both ends of the fixed plug connector C83. The two connectors use the self - contained guide pins to guide and plug into the corresponding floating socket connectors (including the floating socket connector B78 and the floating socket connector C79) on the middle cabin component 7. In this embodiment, four guiding grooves II 88 are evenly distributed in a circumferential direction on the rear cabin housing 84. Before the connectors B (including the fixed plug connector B82 and the floating socket connector B78) and the connectors C (the fixed plug connector C83 and the floating socket connector C79) are plugged in, the guiding grooves II 88 on the rear cabin housing 84 are correctly plugged into the middle cabin component 7 to ensure the correct plug - in of the subsequent connectors A and B.

[0083] The middle cabin component 7 includes a middle cabin housing 76 and electrical components 77, as Figure 10 shown. A floating socket connector A75 is installed at the front end of the electronic component 77 for plugging into the fixed end plug connector A62 of the front cabin component 6 to achieve electrical connection. A floating socket connector B78 and a floating socket connector C79 are installed at the rear side of the electronic component 77, which are respectively used for plugging into the fixed plug connector B82 and the fixed plug connector C83 of the rear cabin component 8 to achieve electrical connection. In this embodiment, four guiding grooves I 710 are evenly distributed in a circumferential direction on the inner wall of the front end of the middle cabin housing 76, and 4 guiding columns II711 are evenly distributed in a circumferential direction at the rear end of the middle cabin housing 76, as Figure 10-2 、 Figure 10-3 shown. Before the connectors A, B, and C are plugged in, through the pre - plugging between the corresponding guiding columns and guiding grooves, it plays a rough guiding role when the middle cabin component 7 is integrally plugged into the front cabin component 6 and the rear cabin component 8.

[0084] The electrical components 77 in the middle 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 in the middle cabin housing 76 by 8 circumferential screws and form a whole component, as Figure 10 and Figure 15 、 Figure 15-1As shown. The left electronic component 724 includes a left bracket 733 and three matching electronic modules (namely, electronic module I 727, electronic module II 728, and electronic module III 729). Plug connectors I 730, II 731, and III 732 are respectively arranged on the electronic module I 727, electronic module II 728, and electronic module III 729. The left bracket 733 has a cavity inside. Each electronic module is axially pushed into the left bracket 733 in sequence and is respectively fixed on the left bracket 733 by a plurality of circumferential screws (such as Figure 15-1 , Figure 15-2 , Figure 16-1 , Figure 16-2 shown). Electrical component screw mounting holes II 74 are arranged on the left bracket 733. By matching with the electrical component screw mounting holes II 74 with screws, the left electronic component 724 is fixed in the middle cabin housing 76.

[0085] The right electronic component 725 includes a right bracket 742, an electrical interconnection assembly 726, and an electronic module IV 743. First, the electrical interconnection assembly 726 is pushed in and fixed on the right bracket 742 by screws (such as Figure 17 and Figure 17-1 shown), and then the electronic module IV 743 is axially pushed into the right bracket 742 and fixed on the right bracket 742 by a plurality of screws (such as Figure 15-1 shown), and 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. PCB board nut mounting holes 737 are arranged on the rigid-flex PCB board 736. Mounting nut kits 734 are arranged on the PCB board nut mounting holes 737. Bracket screw mounting holes 738 are arranged on the right bracket 742. The PCB board mounting screws 735 are used to pass through the bracket screw mounting holes 738 and screw into the mounting nut kits 734, so as to fix the rigid-flex PCB board 736 on the right bracket 742. Socket connectors I 739, II 740, and III 741 are connected to the rigid-flex PCB board 736. Electrical component screw mounting holes II 74 are arranged on the right bracket 742. By matching with the electrical component screw mounting holes II 74 with screws, the right electronic component 725 is fixed on the middle cabin housing 76.

[0086] The left electronic component 724 and the right electronic component 725 are butted and then fixed into an integral electronic cabin component by screws, and are simultaneously fixed within the middle cabin housing 76. The socket connector I 739, the socket connector II 740, and the socket connector III 741 are respectively plugged and locked with the plug connector I 730, the plug connector II 731, and the plug connector III 732 on the left electronic module to achieve electrical connection. The rigid-flex PCB board 736 is also connected to the floating socket connector A 75, the floating socket connector B 78, and the floating socket connector C 79. The floating socket connector A 75 is floatingly arranged on the mounting panel located on the left bracket 733 by screws (see Figure 15 ), and the floating socket connector B 78 and the floating socket connector C 79 are floatingly arranged on the mounting panel located within the middle cabin housing 76 by screws.

[0087] A guide pin A 64 and a guiding chamfer 67 are provided on the fixed plug connector A 62. The floating socket connector A 75 includes a socket connector housing A 717, and the socket connector housing A is provided with a guide hole A 716 for guiding and plugging with the guide pin A 64. A connector mounting panel A 718 is arranged within the middle cabin housing 76. The floating connector mounting screw A 719 passes through the through hole on the socket connector housing A 717 and is then screwed into the threaded hole on the connector mounting panel A 718. There is a floating gap 10 between the floating connector mounting screw A 719 and the through hole on the socket connector housing A 717, enabling the floating socket connector A 75 to radially float within the middle cabin housing 76 when being plugged with the fixed plug connector A 62. When the connector A is being plugged, the guide pin A 64 first inserts into the guide hole A 716. If the connector A has a radial deviation, under the guidance of the guide pin A 64 and the guide hole A 716, the floating socket connector A 75 radially floats to align it with the fixed plug connector A 62 in the radial direction to ensure insertion. A chamfer is provided at one of the plugging ends of the guide pin A 64 and the guide hole A 716, or both are provided with chamfers, so that the plugging ends of the guide pin A 64 and / or the guide hole A 716 form corresponding pointed parts and flared openings, enabling the guide pin A 64 and the guide hole A 716 to achieve plugging within the floating range, and under the action of the plugging force, the floating socket connector A 75 radially floats to align the floating socket connector A 75 with the fixed plug connector A 62.

[0088] A guiding pin B85 is provided on the fixed plug connector B82. The floating socket connector B78 includes a socket connector housing B721, and a guiding hole B714 for guiding and mating with the guiding pin B85 is provided on the socket connector housing B721. A connector mounting panel B720 is arranged in the middle cabin housing 76. The floating connector mounting screw B712 passes through a through hole on the socket connector housing B721 and is screwed into a threaded hole of the connector mounting panel B720. There is a floating gap 10 between the floating connector mounting screw B720 and the through hole on the socket connector housing B721, so that the floating socket connector B78 can radially float in the middle cabin housing 76 when mating with the fixed plug connector B82. When the connectors B are mated, the guiding pin B85 first inserts into the guiding hole B714. If there is a radial deviation in the connectors B, under the guidance of the guiding pin B85 and the guiding hole B714, the floating socket connector B78 radially floats to align it with the fixed plug connector B82 in the radial direction to ensure mating. Chamfers are provided on one of the mating ends of the guiding pin B85 and the guiding hole B714, or both are provided with chamfers, so that the mating ends of the guiding pin B85 and / or the guiding hole B714 form corresponding pointed parts and flared mouths, enabling the guiding pin B85 and the guiding hole B714 to achieve mating within the floating range, and under the action of the mating force, the floating socket connector B78 radially floats to align the floating socket connector B78 with the fixed plug connector B82.

[0089] A guiding pin C87 is provided on the fixed plug connector C83, and a plug connector mounting panel C89 is provided inside the rear cabin housing 84. The fixed plug connector C83 is fixed to the plug connector mounting panel C89 by fixing connector mounting screws C86. The floating socket connector C79 includes a socket connector housing C723, and a guiding hole C715 for guiding and mating with the guiding pin C87 is provided on the socket connector housing C723. A connector mounting panel C722 is provided inside the middle cabin housing 76. The floating connector mounting screw C713 passes through a through hole on the socket connector housing C723 and is screwed into a threaded hole of 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, so that the floating socket connector C79 can radially float inside the middle cabin housing 76 when mating with the fixed plug connector C82. When the connector C is mated, the guiding pin C87 first inserts into the guiding hole C715. If the connector C has a radial deviation, under the guidance of the guiding pin C87 and the guiding hole C715, the floating socket connector C79 radially floats to align it with the fixed plug connector C82 in the radial direction to ensure mating. Chamfers are provided on one of the mating ends of the guiding pin C87 and the guiding hole C715, or both are provided with chamfers, so that the mating ends of the guiding pin C87 and / or the guiding hole C715 form corresponding pointed parts and flared mouths, enabling the guiding pin C87 and the guiding hole C715 to achieve mating within the floating range. Under the action of the mating force, the floating socket connector C79 radially floats to align the floating socket connector C79 with the fixed plug connector C83.

[0090] The process of realizing the mating and floating function among the front cabin component 6, the middle cabin component 7, and the rear cabin component 8 is described as follows:

[0091] The first step: Coarse guidance among the front cabin component 6, the middle cabin component 7, and the rear cabin component 8. Corresponding guiding grooves and guiding columns are designed on the circumferences of the corresponding housings of the front cabin component 6, the middle cabin component 7, and the rear cabin component 8. As shown in Figure 9-2 、 Figure 10-2 、 Figure 10-3 、 Figure 11-2 When docking the cabin sections, the radial accuracy is controlled by the shaft-hole fit (the mating end of the front cabin component 6 inserts into the front mating end of the middle cabin component 7, and the rear mating end of the middle cabin component 7 inserts into the mating end of the rear cabin component 8). Rotate each cabin section to dock the guiding grooves and guiding columns, thereby controlling the circumferential angular accuracy. When the cabin sections are axially mated, through the cooperation of the guiding column and the guiding hole and the shaft-hole fit, there will be no axial and radial pitching and yaw between the cabin sections. During the three-cabin mating process, the respective housings first guide the mating. At this time, the front and rear connectors have not made physical contact, which can effectively avoid mechanical damage caused by the impact force of the cabin section mating acting on the connector, as shown in Figure 12As shown, before the connectors of each cabin section are mated, the guiding grooves and guiding columns guide each other to keep the cabin sections mated in the correct direction. As Figure 12-1 The figure shows a schematic diagram of connector A before mating. Figure 12-2 The figure shows schematic diagrams of connector B and connector C before mating. When the guiding grooves and guiding columns guide each other, there is a contact gap 9 between the plugs and sockets of each connector.

[0092] Step 2: Precise guidance between connectors: As the three-cabin component is gradually guided by the guidance between the shells, the guiding pins and guiding holes of the connectors on the three-cabin component start to contact and guide, as Figure 13 shown. As the guiding depth gradually increases, the guiding pins will cooperate with the guiding holes to drive the floating socket connector to have a radial movement relative to the middle cabin shell 76. At this time, there is an over-positioning situation in the cooperation between the three-cabin shell components and between the connectors. In order to eliminate this over-positioning in the cooperation, a floating structure is adopted in the cooperation structure between the floating socket connector and the middle cabin shell 76 where it is located to achieve a clearance fit between them, thereby eliminating the cooperation tolerance between the middle cabin shell 76 and the connector during the mating process, and thus realizing the transition from the rough guidance of the shell mating to the precise guidance between the guiding pins and guiding holes of the connectors, and realizing the floating docking function in terms of structure between the three cabins.

[0093] When the three cabins are docked, first, they are rigidly guided and mated through the cabins. After the cabins are mated to a certain distance, the plug connectors and socket connectors corresponding to connector A, connector B, and connector C on their respective cabins are respectively guided and contacted through their own guiding pins and guiding holes (as Figure 14-1A , Figure 14-1B , Figure 14-2A , Figure 14-2B , Figure 14-3A , Figure 14-3B ), and the plug connectors and socket connectors are guided and mated until the electrical contact parts are in contact. If there is no flexible guidance during the mating process of the plug connectors and socket connectors, it will cause an over-positioning situation in the multi-structure cooperation, which is likely to cause mechanical damage to the connectors. In order to avoid this situation, the present invention respectively adds floating connector mounting screws to the fixation between the socket connectors and the corresponding mounting panels. There is a floating gap 10 between the floating connector mounting screws and the socket connectors, so that the socket connectors can freely float within a certain dimensional range of 360° relative to the mounting panels. This action can eliminate the situation of being jammed when the plug connectors and socket connectors are mated, and thus can effectively eliminate the mechanical damage of the connecting devices during the mechanical docking of the left and right cabins, and realize the precise floating guidance and positioning function between the electronic cabins.

[0094] The beneficial effects of the present invention are summarized as follows:

[0095] 1. Blind plug floating docking can be achieved between cabin sections. Through the guidance of guide posts and guide grooves, it is ensured that each cabin section is inserted in the correct orientation. The socket connector is floatingly arranged in the middle cabin housing 76. When there is a deviation in the position between the plug connector and the socket connector, through the radial floating of the socket connector, docking can be achieved while avoiding mechanical damage to the connector, realizing the de-manual operation of electrical connection, circumventing the problem of wire movement and wear caused by too long cables during traditional manual docking, improving the operability and maintainability of cabin section docking, meeting the requirements of rapid assembly, and achieving "standardization, modularization, and generalization", providing guarantee for the automated assembly of cabin sections and platform incubation. Moreover, the plug connector and the socket connector are pre-set in the corresponding cabin sections, without the need to reserve the length of the cable. After docking, the cable will not shake, avoiding cable damage and not occupying additional space inside the cabin section.

[0096] 2. The integrated interconnection technology is adopted. The electronic modules are stacked in the corresponding brackets (including the left bracket 733 and the right bracket 742) to form the left electronic component 724 and the right electronic component 725. Then, the left electronic component 724 and the right electronic component 725 are docked and fixed in the middle cabin housing 76, realizing the miniaturized design, installation, and use from equipment to modules. The highly integrated and axially stacked layout saves the space occupied by the installation of traditional distributed equipment, solves the dependence of the distributed layout of equipment on the use of connectors and cables, improves the convenience and operability of module installation, and when disassembling, removing the screws in the middle cabin housing 76 can remove the left electronic component 724 and the right electronic component 725 from the middle cabin housing.

[0097] 3. The left electronic component 724 and the right electronic component 725 adopt integrated rigid-flexible electrical interconnection (mainly realized through the rigid-flexible PCB board 736). The overall three-dimensional routing path is clear, with strong operability and maintainability, solving the reliability problem of electrical line interconnection in narrow spaces, as well as problems such as a large number of customizations in the traditional equipment layout, low generalization level, weak system integration optimization, and poor scalability. It has the advantages of light structural weight, small volume, few components, high integration level, and strong expansion ability.

The cabin components include a cabin housing and connectors arranged in the cabin housing.

Guide posts and guide grooves are provided between adjacent cabin components. And between two adjacent cabin components, a fixed plug connector is arranged in one of the cabin components, and a floating socket connector is arranged in the other cabin component. Each cabin component is provided with at least two circumferentially distributed guide posts or guide grooves.
