Description

Technical Field

[0001] This application relates to the field of distribution cabinets, and more particularly to a low-voltage cabinet. Background Technology

[0002] In traditional low-voltage switchgear assembly, electronic components are typically assembled directly inside the cabinet. Due to limited internal space, workers are often severely constrained during assembly, leading to low efficiency. Furthermore, installing multiple electronic components simultaneously inside the cabinet can easily cause interference, further increasing assembly complexity and error rates. This traditional assembly method not only prolongs the production cycle of low-voltage switchgear but may also result in unstable assembly quality, affecting the overall performance and reliability of the product.

[0003] Therefore, this application studies a low-voltage switchgear that is assembled in separate modular units, which effectively avoids the inconvenience caused by workers operating in the limited space of the cabinet, while ensuring that each module is assembled independently without interfering with each other, thereby significantly improving assembly efficiency and enhancing the overall assembly quality and reliability of the low-voltage switchgear. Utility Model Content

[0004] In order to effectively avoid the inconvenience caused by workers operating in the limited space of the cabinet, and to ensure that each module is assembled independently without interfering with each other, thereby significantly improving assembly efficiency and enhancing the overall assembly quality and reliability of the low-voltage cabinet, this application provides a low-voltage cabinet.

[0005] This application provides a low-voltage switchgear, which adopts the following technical solution:

[0006] A low-voltage switchgear includes a cabinet body and a plurality of mounting plates. The mounting plates are detachably connected to the cabinet body and are spaced apart along the height direction of the cabinet body. Each mounting plate is used to mount electronic devices. The mounting plates are provided with connectors for fixing the electronic devices, and the connectors are detachably connected to the cabinet body.

[0007] By adopting the above technical solution, the detachable design of the mounting plate and connectors makes the installation and removal of electronic components on the mounting plate more flexible and convenient. Furthermore, installing electronic components on the mounting plate independently of the cabinet avoids installation inside the cabinet, thus avoiding the inconvenience caused by working in the limited space of the cabinet. Moreover, the detachable mounting plate allows for reasonable layout according to the size of the electronic components, making full use of the space inside the cabinet and avoiding mutual interference, thereby significantly improving assembly efficiency and enhancing the overall assembly quality and reliability of the low-voltage cabinet.

[0008] Optionally, the cabinet body is provided with an installation component, and both the connector and the installation component have through holes, through which bolts and nuts are used to fix the connector to the installation component.

[0009] By adopting the above technical solution, the connectors can be easily installed and removed from the cabinet, thereby facilitating the removal and installation of the mounting plate from the cabinet, thus improving assembly efficiency and flexibility.

[0010] Optionally, the connector is provided with a support member, and when the connector is installed on the mounting member, the support member abuts between the connector and the mounting member.

[0011] By adopting the above technical solution, when the connector is installed on the mounting component, the support component can effectively distribute the force borne by the connector, avoid the connector from deforming or being damaged due to excessive local stress, and significantly improve the connection stability between the connector and the mounting component.

[0012] Optionally, the support member has a connecting hole corresponding to the through hole. Bolts and nuts fix the connector and the mounting member through the through hole and the connecting hole, and abut the support member between the connector and the mounting member.

[0013] By adopting the above technical solution, bolts can pass through the connector, support, and mounting parts simultaneously, tightly fixing the three together. The support not only plays a role in buffering and supporting, but also further improves the stability of the connection.

[0014] Optionally, multiple connectors are provided at intervals along the height direction of the mounting plate.

[0015] By adopting the above technical solutions, the mounting plate can install more different electronic devices in a limited space, and can also be installed on any connector, providing greater flexibility for the modular design of low-voltage switchgear.

[0016] Optionally, the central axes of the perforations of the plurality of connectors are not on the same straight line.

[0017] By adopting the above technical solution, the component can be subjected to force at different positions when installed on the mounting component, thus making the connection between the connector and the mounting component more stable.

[0018] Optionally, a heat dissipation mesh is provided between adjacent mounting plates, and the heat dissipation mesh is installed on the cabinet.

[0019] Optionally, the cabinet body is also provided with multiple cabinet doors, which are provided corresponding to the mounting plate.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a low-voltage switchgear. (Refer to...) Figure 1The low-voltage switchgear includes a cabinet body 1 and multiple mounting plates 2. The height and number of mounting plates 2 can be set according to actual needs. The mounting plates 2 are detachably connected to the cabinet body 1 and are spaced apart along the height of the cabinet body 1. The mounting plates 2 are used to install electronic components, allowing for modular installation based on different electronic components to avoid mutual interference. The mounting plates 2 are equipped with connectors 3 for fixing the electronic components, and these connectors 3 are detachably connected to the cabinet body 1. Installing electronic components on the mounting plates 2 independently of the cabinet body 1 avoids installation within the cabinet body 1, preventing inconvenience caused by working in the limited space of the cabinet body 1. Furthermore, the detachable mounting plates 2 allow for a reasonable layout based on the size of the electronic components, making full use of the space within the cabinet body 1, avoiding mutual interference, and thus significantly improving assembly efficiency and enhancing the overall assembly quality and reliability of the low-voltage switchgear.

[0032] In some embodiments, a heat dissipation mesh 8 is provided between adjacent mounting plates 2, and the heat dissipation mesh 8 is screwed onto the cabinet 1. The heat dissipation mesh 8 can isolate adjacent mounting plates 2, preventing mutual interference between electronic components, while also dissipating heat inside the cabinet 1.

[0033] In some embodiments, multiple connectors 3 are spaced apart along the height direction of the mounting plate 2. Multiple connectors 3 can stably fix electronic components while also more stably fixing the mounting plate 2 to the cabinet 1.

[0034] In some embodiments, a mounting member 4 is screwed into the cabinet 1. The mounting member 4 is a trapezoidal plate structure, and the connecting member 3 is a long strip plate structure. The connecting member 3 passes through the mounting plate 2 and is fixed to the mounting plate 2. One end of the connecting member 3 is screwed to fix an electronic device. (Refer to...) Figure 2 Both the other end of the connector 3 and the mounting part 4 have through holes 5, and the through holes 5 of the two are set in a corresponding manner. The bolt and nut fix the connector 3 to the mounting part 4 through the through holes 5. That is, the bolt passes through the connector 3 and the mounting part 4 in sequence and is screwed to the nut, so that the connector 3 is stably installed on the mounting part 4.

[0035] Reference Figure 1 and Figure 2 In some embodiments, the connector 3 is provided with a support member 6, which is a cylindrical structure. When the connector 3 is installed on the mounting member 4, the support member 6 abuts against the connection between the connector 3 and the mounting member 4. The support member 6 provides support, making the connection between the connector 3 and the mounting member 4 more stable.

[0036] Reference Figure 2In some embodiments, the support member 6 has a connecting hole 7 corresponding to the through hole 5. Bolts and nuts fix the connector 3 and the mounting member 4 through the through hole 5 and the connecting hole 7, and the support member 6 abuts between the connector 3 and the mounting member 4. By bolting the bolts through the connector 3, the support member 6 and the mounting member 4 in sequence and screwing them to the nut, the connection stability between the connector 3 and the mounting member 4 is further improved by the support member 6.

[0037] In some embodiments, the central axes of the holes 5 of the plurality of connectors 3 are not on the same straight line, and the holes 5 of the mounting plate 2 are provided in a one-to-one correspondence with the holes 5 of the connectors 3. This allows the connectors 3 and the mounting members 4 to be subjected to forces in different vertical directions, thereby distributing the forces and making the installation between the connectors 3 and the mounting members 4 more stable.

[0038] Reference Figure 3 In some embodiments, the cabinet 1 is also provided with multiple cabinet doors 9, which are corresponding to the mounting plates 2. That is, the height and number of cabinet doors 1 are corresponding to the mounting plates 2 one by one. The cabinet doors 9 can be rotated and connected to the cabinet 1 by means of a pivot or hinge. When inspecting or installing electronic devices, only the corresponding cabinet door 9 needs to be opened, which improves the inspection efficiency and avoids interference from other electronic devices.

[0039] Reference Figure 4 In some embodiments, the mounting plate 2 has a hanging hole 10, the diameter of the upper half of the hanging hole 10 is smaller than the diameter of the lower half, and it is roughly gourd-shaped. The cabinet 1 has a hanging bracket, which can be a bolt or any "T"-shaped fastener. The rod at one end of the "T" shape is fixed to the hole in the cabinet 1, and there is a gap between the end and the cabinet 1. When the mounting plate 2 is installed on the cabinet 1, when the hanging hole 10 is inserted into the hanging bracket, the lower half of the hanging hole 10 passes through the hanging bracket and moves downward, so that the upper half of the hanging hole 10 abuts against the hanging bracket, and the end of the "T" abuts against one side of the mounting plate 2, so that the mounting plate 2 is hung on the hanging bracket, and the mounting plate 2 is pre-fixed, so that the mounting plate 2 can be installed more stably on the cabinet 1.

[0040] The implementation principle of a low-voltage switchgear according to an embodiment of this application is as follows: the detachable design of the mounting plate 2 and the connector 3 makes the installation and removal of electronic components on the mounting plate 2 more flexible and convenient; and by installing electronic components on the mounting plate 2 independently of the cabinet 1, installation inside the cabinet 1 can be avoided, thus avoiding the inconvenience caused by working in the limited space of the cabinet 1. Furthermore, the detachable mounting plate 2 allows for reasonable layout according to the size of the electronic components, making full use of the space inside the cabinet 1, avoiding mutual interference, thereby significantly improving assembly efficiency and enhancing the overall assembly quality and reliability of the low-voltage switchgear.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
