Description

Technical Field

[0001] The present invention belongs to the technical field of electronic device chassis, and particularly relates to a modular integrated chassis that can be flexibly configured and quickly disassembled. Background Art

[0002] In general chassis devices, signal transfer is usually carried out using straight plugs, bent plugs, and cables. For example, the blind plug type electronic chassis disclosed in the patent document with the application number CN202210156827.6 integrates external devices such as electrical connectors, optical signal connectors, and radio frequency connectors by passing them through the rear panel of the box to form an integrated connector rear panel. The integrated connector rear panel is connected to the electrical mother board inside the box through cables. When installing the cable assembly in the chassis, it needs to be installed one by one and bundled and fixed. In this chassis structure, the signal external interface uses a standard single port or rectangular or circular integrated connector, and the contact parts of the external connectors are all connected to radio frequency cables and optical cables. This traditional technical solution makes the disassembly, installation, and maintenance operations of the device complex. It is necessary to disassemble and install each cable one by one, and various connectors used for signal external transfer cannot be disassembled separately. Instead, it is necessary to replace them with the cable assembly at their tails or remove the contact parts. Summary of the Invention

[0003] Aiming at the defect that the connection between the external module and the backplane in the existing chassis by cables leads to complex disassembly and installation, the purpose of the present invention is to provide a modular integrated chassis that can be flexibly configured and quickly disassembled.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A modular integrated chassis that can be flexibly configured and quickly disassembled, including a blind plug module and several functional modules arranged inside the chassis body, and several interface components arranged outside the chassis body. The blind plug module has several first docking surfaces and several second docking surfaces, and the interface components include several external connectors; Blind plug connectors adapted to the corresponding functional modules are provided on the first docking surfaces, and the contact parts III of the external connectors are connected and conducted with the contact parts II inside the blind plug module after passing through the second docking surfaces; A printed circuit board or a cable that is simultaneously connected to the contact part I and the contact part II is provided inside the blind plug module.

[0005] As an improvement of the above technical solution, one of the guide pins and the guide holes is arranged on the first docking surface and the second docking surface, and the other is arranged on the functional module and the interface component.

[0006] As an improvement of the above technical solution, the main body having the second docking surface is detachably connected to the blind plug module.

[0007] As an improvement of the above technical solution, a functional component connected to a printed circuit board or a cable is further provided inside the blind plug module, and the functional component includes a lightning protection device, a filtering device, and a power splitting device.

[0008] As an improvement of the above technical solution, the contact I of the blind plug connector and the contact II in the blind plug module are both floating contacts to adapt to production errors.

[0009] As an improvement of the above technical solution, the interface component further includes a support panel detachably connected to the outside of the chassis body, and the external connector is mounted on the support panel.

[0010] As a further improvement of the above technical solution, an opening is further provided on the chassis body, and the external connector is connected to the second docking surface inside the chassis through the opening.

[0011] As an improvement of the above technical solution, the blind plug module includes a first installation section and a second installation section, and a plurality of first docking surfaces are provided on the first installation section, and a plurality of second docking surfaces are provided on the second installation section.

[0012] As a further improvement of the above technical solution, the first installation section and the second installation section are integrally arranged in an "L" shape.

[0013] As a further improvement of the above technical solution, a maintenance board for maintaining the first installation section is detachably provided on the blind plug module.

[0014] The aforementioned quickly detachable integrated chassis can obtain the following beneficial effects: (1) The cabinet, the functional module, the blind plug module and the interface component are all independent individual units, which can be independently installed, disassembled and replaced, truly realizing the modular design of the interface, signal transmission and function realization. There is no need to disassemble and replace the cable components for each path during the maintenance of traditional electronic equipment, greatly reducing the on-site maintenance time and the possibility of installation errors; (2) The blind plug module, the functional module and the interface component also use guide pins to achieve precise plugging guidance, realizing the quick blind plugging between modules and the quick disassembly and assembly of the modules; (3) The blind plug module with a plurality of first docking surfaces and a plurality of second docking surfaces can plug in one or more groups of functional modules and interface components at different positions at the same time, realizing the conduction of multiple functions and expanding the applicable range of the chassis layout; (4) The quickly replaceable interface component makes it unnecessary to maintain the internal interconnection lines of the equipment when replacing the interface connector, and further reduces the maintenance time of the equipment.

In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without some of these specific details.

[0028] The orientation terms appearing in the following description are all the directions shown in the drawings and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a modular integrated chassis of the present invention that can be flexibly configured and quickly disassembled includes a blind plug module 1 and several functional modules 4 disposed inside the chassis body 5, and several interface components 2 disposed outside the chassis body 5. Several external connectors 22 are also disposed on the interface components 2, and the several external connectors 22 are used to realize signal transmission between the functional module 4 and other electronic devices outside the chassis. The blind plug module 1 has several first docking surfaces 111 and several second docking surfaces 121. Guide structures 3 for facilitating the docking of the functional module 4 and the interface component 2 are respectively disposed on the first docking surface 111 and the second docking surface 121. The setting of the blind plug module 1 makes the functional module 4 and the interface component 2 each form an integral body. By plugging the functional module 4 into the first docking surface 111 and then plugging through the second docking surface 121 with the interface component 2, the modular setting of the functional module 4, the interface component 2, and the blind plug module 1 is realized, and the disassembly and assembly process between various structures in the chassis is simplified.

[0030] Referring to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9, inside the blind plug module 1, there is a printed circuit board or cable that is simultaneously connected to the contact member I 13 and the contact member II, realizing signal conduction between the first docking surface 111 and the second docking surface 121. During installation, the connector on the functional module 4 is inserted and connected to the blind plug connector 14 adapted to the corresponding functional module 4 provided on the first docking surface 111 to form signal conduction. The contact member III 23 of the external connector 22 passes through the second docking surface 121 and is connected and conducted with the contact member II inside the blind plug module 1. Since the interface component 2 used as the interface for the chassis signal to be transferred externally is no longer connected to the blind plug module inside the chassis through a cable, there is no need to disassemble and replace its cable assembly for each path during the maintenance of traditional electronic devices, greatly reducing the on-site maintenance time and the possibility of installation errors. The contact member I 13 and the contact member II of the blind plug connector 14 are both floating contact members. The contact members with a floating structure can adapt to production errors, assembly errors, etc. of the connector, making it easier to realize the plugging process of the connector.

[0031] The blind plug module 1 includes a first installation section 11 and a second installation section 12. The first docking surface 111 is provided on the first installation section 11, and the second docking surface 121 is provided on the second installation section 12. The segmented blind plug module 1 is more conducive to the installation of the functional module 4 and the interface component 2 at different positions. For the segmented blind plug module 1, a first docking surface 111 and a second docking surface 121 can be set. The first docking surface 111 and the second docking surface 121 are respectively connected to a group of functional modules 4 and a group of interface components 2. After segmentation, multiple first docking surfaces 111 and second docking surfaces 121 can also be set. The first docking surface 111 can be set on different surfaces of the first installation section 11 or on multiple surfaces of the first installation section 11. Similarly, the second docking surface 121 can also be set on different surfaces of the second installation section 12, or multiple second docking surfaces 121 can be set on multiple surfaces of the second installation section 12. Such a diverse chassis structure expands the scope of use of the chassis.

[0032] Refer to Figure 5 , as an implementation manner of the present invention, the first installation section 11 and the second installation section 12 are integrally provided in an "L" shape. The blind plug module 1 provided in an "L" shape fits the commonly used chassis on the market. The right-angled structure fits the two right-angled sides of the chassis, and the first docking surface 111 is provided on the front wall surface of the first installation section 11. The second docking surface 121 is provided on the right side surface of the second installation section 12 that fits the chassis. In this way, the functional module 4 and the interface component 2 do not affect each other during insertion and installation. While facilitating the installation of the functional module 4 and the interface component 2, the functional component 15 is exactly located in the square space formed by the two inner surfaces of the "L"-shaped blind plug module 1 and the inner wall of the chassis, and it is convenient to open holes on the side of the chassis to connect the interface component 2 provided outside the chassis to the second docking surface 121 inside the chassis.

[0033] As the second implementation mode of the present invention, the first installation section 11 and the second installation section 12 are integrally arranged in a "T" shape. The blind plug module 1 arranged in a "T" shape is more conducive to arranging multiple groups of functional modules 4. Specifically, the first installation section 11 is connected to the middle of the second installation section. The second docking surface 121 on the second installation section 12 fits with the chassis, while the front wall surface and the rear wall surface that are relatively distributed on the first installation section 11 both form the first docking surface 111. A plurality of functional modules 4 are respectively inserted on the two first docking surfaces 111, so that a plurality of functional modules 4 are simultaneously inserted on the two relatively distributed wall surfaces of one blind plug module 1. The multiple functional modules 4 inserted on both sides of the first installation section 11 can not only make the layout between each module in the chassis more compact, but also balance the force after the blind plug module 1 is inserted, make the module structure in the chassis more stable, and increase the service life of the blind plug module 1, the printed circuit board and the contacts in the module.

[0034] As the third implementation mode of the present invention, the first installation section 11 and the second installation section 12 are still integrally arranged in an "L" shape, but the upper wall surface of the first installation section 11 is flush with the upper wall surface of the second installation section 12, and the lower wall surface of the first installation section 11 is higher than the lower wall surface of the second installation section 12. At this time, the front wall surface and the lower wall surface of the first installation section 11 both form the first docking surface 111. A plurality of functional modules 4 are inserted on the front wall surface, and a plurality of functional modules 4 are also inserted on the lower wall surface, so that a plurality of functional modules 4 in the chassis are distributed in two layers in the vertical direction. The foregoing layout increases the setting area of the functional modules 4 in the chassis and further enlarges the use range of the chassis.

[0035] As the fourth implementation mode of the present invention, the difference from the third implementation mode is that: the upper wall surface of the first installation section 11 is lower than the upper wall surface of the second installation section 12, and the lower wall surface of the first installation section 11 is higher than the lower wall surface of the second installation section 12. At this time, the front wall surface, the upper wall surface and the lower wall surface of the first installation section 11 all form the first docking surface 111. A plurality of functional modules 4 are inserted on the front wall surface, a plurality of functional modules 4 are also inserted on the upper wall surface, and a plurality of functional modules 4 are also inserted on the lower wall surface, so that a plurality of functional modules 4 in the chassis are distributed in three layers in the vertical direction, further improving the utilization rate of the internal space of the chassis. Further, following the ideas of the foregoing third implementation mode and fourth implementation mode, at least one of the front wall surface, the rear wall surface, the upper wall surface, the lower wall surface, and the left wall surface of the first installation section 11 can be made to form the first docking surface 111 according to requirements.

[0036] Refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 9, for the blind mating module 1, to facilitate the plugging and unplugging of the functional module 4 and the interface component 2, guide holes 32 are further provided on the first mating surface 111 and the second mating surface 121. Guide pins 31 are provided on both the functional module 4 and the interface component 2. Before the contacts on the functional module 4 are plugged into the contacts III 23 of the external connector 22 on the interface component 2, the guide pins 31 and the guide holes 32 are first plugged and matched to form the function of plugging guidance, restricting the contacts on the functional module 4 and the contacts III 23 to the correct plugging positions, and realizing the precise blind mating of the functional module 4 and the interface component 2. Of course, in other embodiments of the present invention, guide pins 31 can be provided on the first mating surface 111 and the second mating surface 121, and guide holes 32 are provided on both the functional module and the interface component.

[0037] Referring to Figure 10 , inside the blind mating module, in addition to a printed circuit board, other functional components 15 are also provided. The functional components 15 can be set according to the modules in the chassis, which can not only protect the existing modules in the chassis but also increase the functions of the existing modules in the chassis. The functional components 15 are connected to the printed circuit board or cables inside the blind mating module 1. In this embodiment, the functional components 15 can include lightning protection devices, filtering devices, power splitting devices, etc.

[0038] Referring to Figure 10 , as an implementation manner of the present invention, to facilitate the maintenance and disassembly of the printed circuit board, connectors, and other functional components 15 inside the blind mating module 1, the blind mating module 1 is detachably provided with a maintenance board 6 for maintaining the first installation section 11. The maintenance board 6 is arranged on the side of the first installation section 11 facing away from the first mating surface 111. The maintenance board 6 is detachably arranged on the first installation section 11 through detachable screws. After disassembly, the interconnection lines inside the blind mating module 1 can be directly accessed for inspection of the interconnection lines inside the blind mating module 1. Similarly, the main body having the second mating surface 121 is detachably connected to the blind mating module 1. The detachable second mating surface main body can realize the internal inspection function of the second installation section 12 on the blind mating module 1, and at the same time, a plugging channel for the contacts III 23 of the external connector 22 to insert into the blind mating module 1 can be provided through the second mating surface 121, so as to ensure the contact conduction between the contacts III 23 of the external connector 22 and the contacts II inside the blind mating module 1.

[0039] For the above embodiments, for the interface component 2 disposed outside the chassis, it further includes a support panel 21 detachably connected to the side surface of the chassis body 5, and the external connector 22 is inserted through the support panel 21. The setting of the support panel 21 integrates a plurality of external connectors 22 together, facilitating the insertion of the external connectors 22. After the external connector 22 is inserted into the second docking surface 121, it is vulnerable to external interference when located outside the chassis. Therefore, increasing the detachable installation of the support panel 21 on the chassis housing protects the external connector 22 after insertion and ensures the stability of the signal contact of the connector. For the support panel 21 installed outside the chassis, the chassis is provided with openings corresponding to the second docking surface 121, and the external connectors 22 disposed outside the chassis are connected to the second docking surface 121 inside the chassis through the openings.

[0040] As another embodiment of the present invention, in order to facilitate the maintenance and disassembly of the interconnection lines inside the second installation section 12, the blind plug module 1 is detachably provided with a repair board 6 for maintaining the second installation section 12. The repair board 6 is disposed on a side surface of the second installation section 12 different from the second installation surface. The repair board 6 is detachably provided on the second installation section 12 by detachable screws. After disassembly, the interconnection lines inside the blind plug module 1 can be directly accessed for inspection of the interconnection lines inside the blind plug module 1.

[0041] The above are only the preferred embodiments of the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
