Abstract
Description
Technical Field
[0001] This invention relates to the field of cable branch box technology, and in particular to a high-efficiency assembly and easy-to-maintain installation device and a cable branch box. Background Technology
[0002] Cable branch boxes are used only for cable branching. Their main function is to split or transfer cables. Currently, various core electrical components inside cable distribution boxes, such as residual current devices (RCDs), shunts, and switches, are generally fixed using bolt fastening. When a large number of electrical components need to be integrated into the box, the number of bolts required also increases significantly. This not only makes the initial assembly process more cumbersome and complex, extending the overall installation time, but also significantly increases the difficulty of operation for workers and reduces the overall efficiency of maintenance work during subsequent equipment inspection, maintenance, or component replacement due to the large number of bolts being disassembled and reassembled.
[0003] Therefore, existing cable distribution boxes are inconvenient for disassembling and maintaining a large number of electrical components. Summary of the Invention
[0004] Based on this, the purpose of the present invention is to provide an efficient assembly and easy-to-maintain installation device and cable branch box, so as to solve the technical problem in the prior art that existing cable branch boxes are inconvenient for disassembling and maintaining a large number of electrical components.
[0005] One aspect of the present invention is to provide an efficient assembly and easy maintenance installation device for use in a cable branch box, for detachably installing electrical components in the cable branch box, wherein the electrical components are provided with mounting holes, and the installation device includes multiple fixed brackets, as well as an elastic pressing carrier and multiple folding fixing modules disposed on each of the fixed brackets; Multiple fixing brackets are used to install in the cable branch box according to the arrangement of the electrical components, such that the folding fixing modules on each pair of adjacent fixing brackets correspond to the corresponding mounting holes in the electrical components; The folding and fixing module includes an elastic folding component and a connector with a folding cavity. One end of the connector is connected to the fixing bracket, and the other end passes through the elastic pressing carrier and is rotatably connected to the elastic folding component. When the mounting through hole is fitted into the connector, the elastic folding component is pressed and folded towards the folding cavity, and then folded outward from the folding cavity, so that the electrical component is fixed to the fixing bracket by the elastic folding component. The elastic gap between the elastic pressing carrier and the fixed bracket is larger than the maximum movement space of the elastic folding component during the folding process.
[0006] Furthermore, the folding and fixing module also includes a first elastic element, and the elastic pressing carrier is elastically connected to the fixing bracket through the first elastic element.
[0007] Furthermore, the diameter of the mounting hole is greater than the sum of the cross-sectional dimension of the connector and the maximum movable space dimension of the elastic folding member during the folding process.
[0008] Furthermore, the mounting device also includes an elastic compression module, which is disposed on the outside of the connector; The elastic extrusion module is disposed opposite to the elastic folding member, so that when the elastic folding member fixes the electrical device on the fixed bracket, the elastic extrusion module makes elastic contact with the inner wall of the mounting hole.
[0009] Furthermore, the elastic extrusion module includes an elastic connector and rollers; One end of the elastic connector is connected to the plug-in member, and the other end extends obliquely relative to the length direction of the plug-in member and is rotatably connected to the roller.
[0010] Furthermore, the mounting device also includes a transmission module and a pressure application module; The transmission module includes a transmission unit and a transmission component having at least one guide portion; the pressure application module includes an elastic pressure plate having a guide cavity formed therein. The transmission component is disposed inside the plug-in component and is connected to the elastic folding component via the transmission unit, so that when the elastic folding component folds relative to the plug-in component, the transmission component reciprocates relative to the plug-in component. The guide portion is located within the guide cavity, so that when the transmission member reciprocates, it drives the elastic pressure plate to abut or separate towards the inner wall of the mounting hole.
[0011] Furthermore, the transmission unit includes a locking tooth portion disposed on the elastic folding member and a rack portion disposed on the transmission member, wherein the locking tooth portion engages with the rack portion.
[0012] Furthermore, the transmission module also includes a guide plate and a second elastic element, the guide plate being disposed on the plug-in member, and the second elastic element being connected to the elastic pressure plate; In this embodiment, a portion of the elastic pressure plate is fitted onto the guide plate, thereby forming a guide area in the guide plate that moves in the same direction as the elastic pressure plate.
[0013] Furthermore, the connector is provided with a cavity for accommodating the elastic pressure plate and the second elastic member.
[0014] Another aspect of the present invention is to provide a cable branch box, including a branch box body and the aforementioned efficient assembly and easy maintenance installation device, wherein the installation device is used for detachable installation within the branch box body.
[0015] Compared with existing technologies, the advantages of using the efficient assembly and easy-to-maintain installation device shown in this invention are as follows: The present invention provides a high-efficiency assembly and easy-maintenance installation device, comprising multiple fixed supports, elastic pressing carriers and multiple folding fixing modules disposed on each fixed support. The folding fixing modules on each pair of adjacent fixed supports correspond to the corresponding mounting holes in the electrical components. This ensures that during installation of the electrical components in a cable branch box, the four mounting holes in the electrical components correspond to two folding fixing modules in two adjacent rows. During installation, the mounting holes are manually inserted into the connectors of the folding fixing modules, causing the elastic folding components to fold towards the folding cavity. During insertion, the elastic pressing carrier is compressed by the electrical components and slides elastically in the forward direction. After the mounting holes are fully inserted into the connectors, the elastic folding components fold outward from the folding cavity. The elastic folding components are used to secure the installation. The mounting body is positioned to limit the movement, while the elastic pressing carrier loses pressure and slides in the reverse direction, thus securing the electrical component. When the electrical component needs to be disassembled for maintenance, the component is manually pressed, causing the elastic pressing carrier to press down again, resulting in the elastic pressing carrier being squeezed by the component and sliding forward elastically. At this time, the elastic folding component is exposed to the outside. Through manual operation, the elastic folding component is folded towards the folding cavity to complete the disassembly of the electrical component. This design can change the existing technology that uses a large number of bolts for fixing, achieving efficient installation and easy maintenance. Furthermore, since each fixing bracket has multiple folding fixing modules, multiple parallel electrical components can be installed and disassembled by multiple people working together, further improving the practicality of this application.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] First Embodiment Please see Figure 1 and Figure 7As shown, the efficient assembly and easy-maintenance installation device in the first embodiment of the present invention is applied in the cable branch box 100 and is used to detachably install the electrical component 200 in the cable branch box 100. The electrical component 200 is provided with mounting holes 210. It should be noted that the mounting holes 210 are part of the electrical component 200. Specifically, there is a mounting hole 210 at each of the four ends of the electrical component 200. That is to say, one electrical component 200 has four mounting holes 210.
[0023] To facilitate the disassembly, assembly, and repair of a large number of electrical components 200, in this embodiment, the installation device 300 includes multiple fixed brackets 310, as well as an elastic pressing carrier 320 and multiple folding fixing modules 330 disposed on each fixed bracket 310. Multiple fixing brackets 310 are used to install in the cable branch box 100 according to the arrangement of electrical components 200, such that the folding fixing module 330 on each pair of adjacent fixing brackets 310 corresponds to the corresponding mounting hole 210 in the electrical component 200. The folding and fixing module 330 includes an elastic folding member 331 and a plug-in member 333 having a folding cavity 332. One end of the plug-in member 333 is connected to the fixing bracket 310, and the other end is rotatably connected to the elastic folding member 331 through an elastic pressing carrier 320. When the plug-in member 333 is inserted into the mounting through hole, the elastic folding member 331 is pressed and folded towards the folding cavity 332, and then folded outward from the folding cavity 332, so that the electrical component 200 is fixed to the fixing bracket 310 through the elastic folding member 331. Among them, the elastic gap between the elastic pressing carrier 320 and the fixed bracket 310 is larger than the maximum movement space of the elastic folding member 331 during the folding process.
[0024] In specific implementation, multiple fixed brackets 310 are used to install the electrical components 200 in the cable branch box 100 according to the arrangement of the components 200. The folding fixing modules 330 on each pair of adjacent fixed brackets 310 correspond to the corresponding mounting holes 210 in the electrical components 200. During installation of the electrical components 200 in the cable branch box 100, the four mounting holes 210 in the electrical components 200 will correspond to two folding fixing modules 330 in two adjacent rows. During installation, the mounting holes 210 are manually inserted into the connectors 333 of the folding fixing modules 330, causing the elastic folding member 331 to fold towards the folding cavity 332. During insertion, the elastic pressing carrier 320 is compressed by the electrical components 200 and slides elastically in the forward direction. When the mounting holes 210 are fully inserted into the connectors 333, the elastic folding member 331 folds towards the direction outside the folding cavity 332. The elastic folding member 331 is used to... The mounting hole 210 limits the movement, while the elastic pressing carrier 320 loses pressure and slides in the reverse direction, thus fixing the electrical component 200. When the electrical component 200 needs to be disassembled for maintenance, the component 200 is manually pressed, causing the elastic pressing carrier 320 to press the component 200 again. This causes the elastic pressing carrier 320 to be squeezed by the component 200 and slide in the forward elastic direction. At this time, the elastic folding member 331 will be exposed to the outside. Through manual operation, the elastic folding member 331 will be folded towards the folding cavity 332 to complete the disassembly of the electrical component 200. This setting can change the existing technology that uses a large number of bolts for fixing, achieving efficient installation and easy maintenance. Furthermore, since each fixing bracket 310 has multiple folding fixing modules 330, multiple parallel electrical components 200 can be installed and disassembled by multiple people working together, further improving the practicality of this application.
[0025] In some practical applications, the folding and fixing module 330 also includes a first elastic element 334. The elastic pressing carrier 320 is elastically connected to the fixing bracket 310 through the first elastic element 334. Specifically, the first elastic element 334 can be a spring in the prior art.
[0026] In some preferred embodiments, the diameter of the mounting hole 210 is larger than the sum of the cross-sectional dimension of the plug-in 333 and the maximum movable space dimension of the elastic folding member 331 during the folding process. The size difference facilitates the installation of the electrical component 200. However, since the size difference may cause the electrical component 200 to wobble after assembly, in some optional embodiments, the mounting device 300 also includes an elastic compression module 340, which is located on the outside of the plug-in 333. The elastic extrusion module 340 is arranged opposite to the elastic folding member 331 so that when the elastic folding member 331 fixes the electrical device 200 on the fixed bracket 310, the elastic extrusion module 340 is in elastic contact with the inner wall of the mounting hole 210.
[0027] Specifically, the elastic extrusion module 340 includes an elastic connecting plate 341 and a roller 342. One end of the elastic connecting plate is connected to the plug 333, and the other end extends obliquely relative to the length direction of the plug 333 and is rotatably connected to the roller 342. Through the setting of the elastic extrusion module 340, the elastic connecting plate 341 will drive the roller 342 to always be tightly fitted with the inner wall of the mounting hole 210, so as to improve the stability of the electrical device 200 after installation.
[0028] In addition, in some alternative embodiments, the mounting device 300 also includes a transmission module 350 and a pressure application module 360; The transmission module 350 includes a transmission unit 351 and a transmission member 353 having at least one guide portion 352, and the pressure module 360 includes an elastic pressure plate 362 having a guide cavity 361. The transmission component 353 is disposed in the plug-in component 333 and is connected to the elastic folding component 331 through the transmission unit 351, so that when the elastic folding component 331 folds relative to the plug-in component 333, the transmission component 353 reciprocates relative to the plug-in component 333. The guide portion 352 is located inside the guide cavity 361, so that when the transmission member 353 reciprocates, it drives the elastic pressure plate 362 to abut or separate towards the inner wall of the mounting hole 210.
[0029] Specifically, the transmission unit 351 includes a locking tooth portion 3511 disposed on the elastic folding member 331 and a rack portion 3512 disposed on the transmission member 353. The locking tooth portion 3511 meshes with the rack portion 3512. The transmission module 350 also includes a guide plate 354 and a second elastic member 355. The guide plate 354 is disposed on the plug-in member 333, and the second elastic member 355 is connected to the elastic pressure plate 362. A portion of the elastic pressure plate 362 is sleeved on the guide plate 354, so that a guide area is formed in the guide plate 354 in the same direction of movement as the elastic pressure plate 362. Furthermore, the plug-in member 333 is provided with a receiving cavity 370 for accommodating the elastic pressure plate 362 and the second elastic member 355.
[0030] Please see Figure 6As shown, during specific operation, when the elastic folding member 331 folds towards the folding cavity 332, the elastic folding member 331 will drive the locking tooth 3511 to rotate in the forward direction. The locking tooth 3511 engages with the rack 3512, causing the transmission member 353 to slide in the forward direction relative to the insertion member 333. The guide part 352 is located in the guide cavity 361, so the guide part 352 moves simultaneously according to the moving direction of the transmission member 353. The guide cavity 361 has a guiding function, causing the elastic pressure plate 362 to move towards the interior of the receiving cavity 370. The movement of the elastic pressure plate 362 can avoid the elastic pressure plate 362 from obstructing the movement of the mounting hole 210.
[0031] When the elastic folding member 331 folds outward from the folding cavity 332, the elastic folding member 331 will drive the locking tooth part 3511 to rotate in the opposite direction. By using the locking tooth part 3511 to mesh with the rack part 3512, the transmission member 353 will slide in the opposite direction relative to the plug member 333. By using the elastic action of the second elastic member 355, the elastic pressure plate 362 can fit tightly against the inner wall of the mounting hole 210.
[0032] It should be noted that the pressing direction of the elastic pressure plate 362 is opposite to that of the roller 342, which helps to effectively fix the mounting hole 210 in multiple positions, achieving a double fixing effect and effectively ensuring the stability of the electrical component 200 after installation.
[0033] In summary, the efficient assembly and easy-maintenance installation device provided in the first embodiment of the present invention includes multiple fixed brackets 310, and elastic pressing carriers 320 and multiple folding fixing modules 330 disposed on each fixed bracket 310. By having the folding fixing modules 330 on each pair of adjacent fixed brackets 310 correspond to the corresponding mounting holes 210 in the electrical component 200, when the electrical component 200 is installed in the cable branch box 100, the four mounting holes 210 in the electrical component 200 will be aligned with the mounting holes 210 in the electrical component 200. Two folding fixing modules 330 in two adjacent rows correspond to each other. During installation, the mounting hole 210 is manually inserted into the connector 333 of the folding fixing module 330, causing the elastic folding member 331 to fold towards the folding cavity 332. During insertion, the elastic pressing carrier 320 is compressed by the electrical device 200 and slides forward elastically. When the mounting hole 210 is fully inserted into the connector 333, the elastic folding member 331 will fold outward from the folding cavity 332. The device is folded over, and the elastic folding component 331 limits the mounting hole 210. At the same time, the elastic pressing carrier 320 loses pressure and slides in the reverse direction, thereby fixing the electrical component 200. When the electrical component 200 needs to be disassembled for maintenance, the device 200 is pressed manually, causing the elastic pressing carrier 320 to press the device 200 again. This causes the elastic pressing carrier 320 to slide forward elastically under the pressure of the device 200. At this time, the elastic folding component 331 will be exposed to the outside. Through manual operation, the elastic folding component 331 will fold towards the folding cavity 332 to complete the disassembly of the electrical component 200. This design can change the existing technology that uses a large number of bolts for fixing, achieving efficient installation and easy maintenance. Furthermore, since each fixing bracket 310 has multiple folding fixing modules 330, multiple parallel electrical components 200 can be installed and disassembled by multiple people working together, further improving the practicality of this application.

Figures 1-7 As shown, a cable branch box 100 provided in the second embodiment of the present invention includes a branch box body and the high-efficiency assembly and easy-maintenance installation device 300 of the first embodiment described above, wherein the installation device 300 is used to be detachably installed in the branch box body.
[0035] In a cable branch box provided in the second embodiment of the present invention, the installation device 300 of the first embodiment is used to facilitate the installation of multiple electrical components 200 into the branch box body. This arrangement can change the fixing method of using a large number of bolts in the prior art, achieving the effect of efficient installation and easy maintenance. Furthermore, since each fixing bracket 310 in the installation device 300 has multiple folding fixing modules 330, multiple parallel electrical components 200 can be installed and disassembled according to the collaborative operation of multiple people during the operation, further improving the practicality of this application.
