Description

Technical Field

[0001] This utility model relates to the field of electrical component mounting housing technology, specifically a lightweight modular housing. Background Technology

[0002] The housing, or encapsulation shell, provides a closed installation space for electrical components. The housing covers and protects the electrical components. In an electrical device, the control electrical components consist of two parts: the outer shell and the internally encapsulated electrical components.

[0003] Existing housings are single, integrated units when installing electrical components. Different components are divided into sections within the housing, meaning all components are integrated and assembled within the same single unit. However, when repairing or maintaining a single component, the entire housing must be opened, exposing all components. This is inconvenient for repairing individual components, and exposed components may be accidentally damaged during maintenance. Furthermore, the number of components varies, requiring multiple housings of different sizes for assembly, making it difficult to easily adjust the housing according to the number of components being assembled.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a lightweight modular shell. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight modular housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight modular housing, comprising a left end shell, an extension shell on the right side of the left end shell, and a right end shell on the right side of the extension shell. Slots are provided on the front and rear sides of the right side of both the left end shell and the extension shell. Insert blocks are fixedly connected to the front and rear sides of the left side of both the extension shell and the right end shell. A convergence groove is provided on the front and rear sides of the upper surface of each slot. A thrust spring is fixedly connected to the inner surface of each convergence groove. A stop block is fixedly connected to the end of each thrust spring near the opening of the convergence groove.

[0007] Preferably, both the slot and the plug are T-shaped, and the height of the plug is less than the opening height of the slot, and the installation positions of the slot and the plug on the surface of the housing correspond to each other.

[0008] Preferably, the end of the stop block that connects to the thrust spring slides on the inner surface of the converging groove, and the end of the stop block away from the thrust spring is located on the upper side inside the slot, and the upper surface of the stop block is set as an inclined surface.

[0009] Preferably, the rear surfaces of the left end shell, the extended shell, and the right end shell are all rotatably connected to a cover, and the cover is connected to each shell using an "L"-shaped rotating member.

[0010] Preferably, the size of the cover matches the area of ​​the upper surface of the shell, and a sealing strip is fixedly connected around the perimeter of the cover near the shell, and the sealing strip matches the width of the shell edge.

[0011] Preferably, the upper front side of the surface of the cover is fixedly connected with a buckle, and the buckle is set in an "L" shape, and the bottom end of the buckle is set in a triangular shape.

[0012] Preferably, the front surfaces of the left end shell, the extended shell, and the right end shell are all provided with grooves on the upper side, and the inner surface of the grooves is provided with positioning grooves on the lower rear side.

[0013] Preferably, the thickness of the recessed groove matches the thickness of the vertical plate of the buckle, and the depth of the positioning groove matches the length of the protruding part at the bottom of the buckle.

[0014] Preferably, a through cavity is provided in the middle of the right side of the surface of the left end shell, and through cavities are also provided in the middle of the left and right sides of the surface of the extended shell, and a through cavity is also provided in the middle of the left side of the surface of the right end shell.

[0015] Preferably, the cavities are positioned and sized to correspond to each other, and the bottom of the inner surface of each cavity is uniformly and fixedly connected with wire clamps.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of slots, inserts, convergence grooves, thrust springs, and stops, allows the expansion shell to be spliced ​​with the left end shell by inserting the insert into the slot. The right end shell is also spliced ​​by inserting the insert into the slot of the expansion shell. The expansion shell can be increased or decreased according to the number of encapsulated electrical components. The left and right end shells can be directly spliced ​​by inserting the insert into the slot. When the insert is inserted into the slot, the insert uses the inclined surface to push the stop to retract into the convergence groove. When the insert is fully inserted into the bottom of the slot, the thrust spring will push the stop to move out of the convergence groove, sealing the opening of the slot, thereby sealing the insert inside the slot for fixation. This allows for fixed assembly of the shells, enabling flexible addition or reduction of shells according to the number of electrical components installed. It also ensures the firmness and stability of the assembled shells, preventing them from easily disassembling or loosening. Furthermore, the shells adopt a modular and independent assembly method, allowing each shell to be disassembled individually. That is, when maintaining different electrical components, they can be disassembled individually without overall disassembly.

[0018] 2. This utility model, through the setting of a cover, sealing strip, buckle, recess, and positioning groove, provides an independent cover for each housing, meaning that each cover can be opened individually. This facilitates the corresponding maintenance of specific packaged electrical components. When the cover is closed, the sealing strip adheres to the edge of the housing, significantly improving the sealing performance of the cover closure. Simultaneously, the buckle inserts into the recess, and the inner wall of the recess pushes the buckle forward. When the bottom end of the buckle is in the positioning groove, the buckle pulls its bottom protrusion into the positioning groove, thereby fixing the cover and ensuring that the cover can be closed stably and securely, providing enclosed protection for the installed electrical components.

[0019] 3. With the design of the through cavity and the wire harness clamp, the wire harnesses of electrical components between the various housings can be interconnected through the through cavity when assembling multiple housings. This allows each electrical component to be stored independently and modularly, while also being able to be connected and used. Furthermore, the interconnected wire harnesses can be fixed with the wire harness clamp to prevent wire harness tangling and improve the neatness of the internal interconnection wiring.

[0025] 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.

[0026] like Figures 1-4As shown, a lightweight modular housing includes a left end shell 1, an extension shell 2 on the right side of the left end shell 1, and a right end shell 3 on the right side of the extension shell 2. Slots 4 are provided on the front and rear sides of the right side of the surfaces of the left end shell 1 and the extension shell 2. Insert blocks 5 are fixedly connected to the front and rear sides of the left side of the surfaces of the extension shell 2 and the right end shell 3. Converging grooves 6 are provided on the front and rear sides of the upper side of the inner surface of the slots 4. A thrust spring 7 is fixedly connected to the inner surface of the converging groove 6. A stop block 8 is fixedly connected to the end of the thrust spring 7 near the opening of the converging groove 6.

[0027] By adopting the above technical solution, the expansion shell 2 can be spliced ​​with the left shell 1 by inserting the plug 5 into the slot 4, and the right shell 3 can also be spliced ​​by inserting the plug 5 into the slot 4 of the expansion shell 2. The expansion shell 2 can be increased or decreased according to the number of encapsulated electrical components, and the left shell 1 and the right shell 3 can be directly spliced ​​by inserting the plug 5 into the slot 4.

[0028] When the insert 5 is inserted into the slot 4, the insert 5 uses the inclined surface to push the stop 8 to retract into the converging groove 6. When the insert 5 is fully inserted into the bottom of the slot 4, the thrust spring 7 will push the stop 8 out of the converging groove 6, blocking the opening of the slot 4, thereby sealing the insert 5 inside the slot 4 for fixation, so that the various shells are fixedly assembled.

[0029] Furthermore, both the slot 4 and the plug 5 are T-shaped, and the height of the plug 5 is less than the opening height of the slot 4. The mounting positions of the slot 4 and the plug 5 on the surface of the housing correspond to each other.

[0030] By adopting the above technical solution, the "T"-shaped insert 5 and slot 4 make it impossible to separate the housing by pulling it laterally from the left and right sides after the housing is connected;

[0031] After the insert 5 is inserted into the slot 4, it is completely submerged inside the slot 4, providing space for the block 8 to be removed from above.

[0032] Furthermore, the end of the stop block 8 that connects to the thrust spring 7 slides on the inner surface of the converging groove 6, and the end of the stop block 8 that is away from the thrust spring 7 is located on the upper side inside the slot 4, and the upper surface of the stop block 8 is set as an inclined surface.

[0033] By adopting the above technical solution, the insert block 5 can directly push the stop block 8 from top to bottom and retract it into the gathering groove 6 using the inclined surface, without the need for manual manipulation.

[0034] The stop block 8 is located at one end inside the convergence groove 6. Under the upper and lower limits of the convergence groove 6, the stop block 8 can be stably slid left and right when subjected to downward pressure.

[0035] Furthermore, the rear surfaces of the left end shell 1, the extended shell 2, and the right end shell 3 are all rotatably connected to a cover 9, and the cover 9 is connected to each shell by an "L"-shaped rotating member.

[0036] By adopting the above technical solution, each housing corresponds to an independent cover 9, that is, the cover 9 can be opened to open a housing individually, which facilitates the corresponding maintenance of specific packaged electrical components.

[0037] The closure of the cover 9 allows the housing to form a closed space, providing full protection for the electrical components installed inside the housing.

[0038] Furthermore, the size of the cover 9 matches the area of ​​the upper surface of the housing, and a sealing strip 10 is fixedly connected around the perimeter of the cover 9 near the housing, and the sealing strip 10 matches the width of the housing edge.

[0039] By adopting the above technical solution, when the cover 9 is closed, the sealing strip 10 will fit against the edge of the shell, thereby greatly improving the sealing performance of the cover 9 when closed.

[0040] Furthermore, the upper front side of the surface of the cover 9 is fixedly connected with a buckle 11, and the buckle 11 is set in an "L" shape, and the bottom end of the buckle 11 is set in a triangular shape.

[0041] The vertical plate of buckle 11 is an elastic plate;

[0042] The front surfaces of the left end shell 1, the extended shell 2, and the right end shell 3 are all provided with a recessed groove 12, and a positioning groove 13 is provided on the lower rear side of the inner surface of the recessed groove 12.

[0043] By adopting the above technical solution, the buckle 11 will be inserted into the recess 12, and the inner wall of the recess 12 will push the buckle 11 to protrude forward. When the bottom of the buckle 11 is located in the positioning groove 13, the buckle 11 will pull the protrusion at its bottom end to insert into the positioning groove 13, thereby fixing the cover 9 and ensuring that the cover 9 can be closed stably and firmly.

[0044] Furthermore, the thickness of the recess 12 matches the thickness of the vertical plate of the buckle 11, and the depth of the positioning groove 13 matches the length of the protruding part at the bottom of the buckle 11.

[0045] By adopting the above technical solution, after the buckle 11 is fixed, it can fill the depression of the groove 12, making the front surface of the shell smoother.

[0046] Furthermore, a through cavity 14 is provided in the middle right side of the surface of the left end shell 1, and a through cavity 14 is also provided in the middle left and right sides of the surface of the extended shell 2, and a through cavity 14 is also provided in the middle left side of the surface of the right end shell 3.

[0047] The positions and sizes of the through cavities 14 correspond to each other, and the bottom of the inner surface of the through cavity 14 is uniformly distributed with fixed wire clamps 15.

[0048] By adopting the above technical solution, when assembling multiple housings, the electrical component wiring harnesses between each housing can be interconnected through the cavity 14, thereby enabling each electrical component to be stored independently and modularly, while also being interconnected and used.

[0049] Interconnected wire harnesses can be secured using wire harness clips 15 to prevent tangling.

[0050] Working Principle: When using this lightweight modular housing, firstly, electrical components are installed inside the left end housing 1 and the right end housing 3. Then, the remaining electrical components are installed in the corresponding number of expansion housings 2. The expansion housings 2 are then connected to the left end housing 1 by inserting the plug 5 into the slot 4. Similarly, the right end housing 3 is connected by inserting the plug 5 into the slot 4 of the expansion housing 2. When the plug 5 is inserted into the slot 4, the plug 5 uses its inclined surface to push the stop 8 to retract into the convergence groove 6. When the plug 5 is fully inserted into the bottom of the slot 4, the thrust spring 7 pushes the stop 8 out of the convergence groove 6, sealing the opening of the slot 4. This secures the plug 5 inside the slot 4, fixing the housings together. After assembly, the wiring harnesses of the electrical components that need to be connected are interconnected through the through cavity 14. The interconnected wiring harnesses are then connected using wire clamps. After all connections and installations are completed, the cover 9 of each individual housing can be rotated and closed. When the cover 9 is closed, the sealing strip 10 will fit against the edge of the housing, thereby greatly improving the sealing performance of the cover 9. At the same time, the buckle 11 will be inserted into the recess 12. The inner wall of the recess 12 will push the buckle 11 to protrude forward. When the bottom end of the buckle 11 is in the positioning groove 13, the buckle 11 will pull the protrusion at its bottom end into the positioning groove 13, thereby fixing the cover 9 and ensuring that the cover 9 can be closed stably and firmly. When inspection or maintenance is required, only the cover 9 of the corresponding electrical component housing needs to be opened, or the housing of the damaged electrical component can be disassembled separately. This means that during inspection and maintenance, it is not necessary to open all the housings or disassemble the entire housing group. This is the working principle of this lightweight modular housing.
