Description

Technical Field

[0001] This utility model relates to the field of cabinet electrical boxes, specifically a socket-connected drawer-type cabinet electrical box. Background Technology

[0002] In the field of stage lighting, the electrical box, as the core component for power supply and control of stage lighting equipment, plays a crucial role in the performance and structural design of stage shows. Traditional stage lighting electrical boxes are mostly fixed in place, with various electrical components directly installed in fixed positions inside the box. This structure has revealed numerous problems in practical use.

[0003] On the one hand, when a component in the electrical box malfunctions, maintenance personnel need to disassemble the entire box and check each component one by one, a tedious and time-consuming process. Since stage performances often have strict schedules, prolonged maintenance could lead to performance delays, causing significant economic losses and negative social impact. Furthermore, the compact layout of components in traditional electrical boxes limits maintenance space, further increasing the difficulty and risk of repairs.

[0004] On the other hand, traditional electrical boxes lack flexibility in expandability and maintainability. With the continuous development of stage lighting technology, new lighting equipment and functions are constantly emerging, placing higher demands on the power supply and control capabilities of electrical boxes. However, the fixed structure of traditional electrical boxes makes it extremely difficult to add or replace electrical components, making it hard to meet the ever-evolving needs of stage lighting systems.

[0005] Furthermore, traditional electrical boxes are inadequate in terms of heat dissipation. Stage lighting equipment generates a significant amount of heat during operation. If this heat cannot be dissipated promptly, it can lead to overheating of electrical components, accelerating their aging, reducing their lifespan, and potentially causing safety accidents. Traditional electrical boxes typically rely solely on natural heat dissipation, which is inefficient and fails to effectively address the heat dissipation problem within the box.

[0006] To address these issues, some improved electrical boxes have emerged on the market. However, these boxes still have limitations in structural design and functional implementation, failing to fully meet the stage lighting industry's demands for efficient, convenient, and reliable electrical boxes. Therefore, there is an urgent need to develop a new type of electrical box suitable for stage lighting to improve the operational stability and ease of maintenance of stage lighting equipment. Utility Model Content

[0007] The present invention aims to solve the above-mentioned technical problems by providing a socket connection for a drawer-type cabinet electrical box.

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0009] The socket connects to the drawer-type cabinet electrical box, including:

[0010] An electrical box body is used to install electrical components. The electrical box body includes a box body and a removable cover.

[0011] At least one independent unit module, specifically including a pull-out frame, said pull-out frame being used to install the electronic components contained in the independent channel;

[0012] At least one connector, which corresponds to an independent unit module and is located inside the housing, and the connector is plugged into the independent unit module;

[0013] The main controller is fixedly installed inside the enclosure and is used to connect the independent unit modules and wiring terminals to achieve centralized control and data interaction of the independent unit modules.

[0014] Furthermore, one side of the enclosure is provided with multiple air inlets, and a cooling fan is provided on the corresponding side. The air inlets and the cooling fan work together to form a forced convection heat dissipation channel.

[0015] Furthermore, one end of the pull-out frame is provided with at least one air switch, which is used to control the on / off state of the corresponding independent unit module.

[0016] Furthermore, the socket connection method between the connector and the independent unit module includes, but is not limited to, a direct plug-in type, a spring type, a snap-fit ​​type, or a strong magnetic attraction type plug-in structure. The connector and the independent unit module are electrically connected through conductive contacts or conductive terminals.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. This utility model adopts a drawer-type independent unit module design. When a certain electrical component malfunctions, the staff only needs to pull out the corresponding independent unit module from the electrical box to repair or replace the faulty component, without disassembling the entire electrical box, greatly shortening the repair time and improving repair efficiency. Moreover, the pull-out structure of the independent unit module provides ample repair space, reducing repair difficulty and risk. In the case of frequent stage performances, this convenient maintenance and repair method can ensure that the stage lighting equipment is restored to normal operation in the shortest possible time, ensuring the smooth running of the performance.

[0019] 2. Since each independent unit module can function as a separate unit, when the stage lighting system needs upgrading or expansion, simply add the corresponding independent unit module and connect it to the wiring connector to integrate the new function. This design allows the electrical box to easily adapt to the continuous development of stage lighting technology and meet the diverse needs of different performance scenarios for lighting equipment. For example, when a stage performance requires the addition of new lighting effects, independent unit modules with specific functions can be added to provide power and control for the new lighting equipment.

[0020] 3. The forced convection heat dissipation channel formed by the air inlet and cooling fan can quickly and effectively dissipate heat from the electrical box, ensuring that the temperature of the electrical components remains within a reasonable range even during long-term continuous operation. Good heat dissipation not only extends the lifespan of the electrical components but also improves the operational stability of the electrical box, reduces the probability of malfunctions caused by overheating, and guarantees the reliable operation of the stage lighting equipment.

[0021] 4. The air switches on the pull-out frame and the control switches on the outside of the cabinet provide users with multiple control methods. Staff can operate individual unit modules on-site via the air switches, or remotely or centrally control each individual unit module from the stage lighting control room via the control switches. This flexible control method can meet the control needs of stage lighting equipment in different scenarios, improve the efficiency and accuracy of stage lighting control, and help achieve richer and more diverse stage lighting effects.

[0022] 5. The diverse socket connection methods between the wiring terminals and independent unit modules, as well as the electrical connections achieved through conductive contacts or terminals, ensure stable current transmission, reduce contact resistance, and improve the working efficiency and connection reliability of the electrical box. During stage performances, stable and reliable connections ensure the normal operation of lighting equipment, preventing malfunctions such as flickering or going out due to connection problems, which could affect the performance.

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly, for example, it can be a fixed connection, a detachable connection, or an integral connection; for those skilled in the art, the specific meaning of the above term in this utility model can be understood according to the specific circumstances.

[0028] I. Working principle of this utility model:

[0029] The socket connection drawer-type cabinet electrical box of this utility model mainly includes the electrical box body, at least one independent unit module, at least one connector and a main controller.

[0030] Electrical Box Body: The electrical box body is used to install electrical components and includes a cabinet and a removable cover. The cabinet provides a stable installation space for the components, while the removable cover facilitates the installation, inspection, and maintenance of the components inside the box. During the equipment debugging phase before a stage performance, staff can easily inspect and adjust the components inside the box by opening the cover, ensuring that the electrical box functions properly during the performance.

[0031] Independent Unit Module: At least one independent unit module is required, each comprising a pull-out frame. The pull-out frame is used to mount the electronic components contained in the independent channel. This design allows each independent unit module to function as a separate unit, performing specific power supply or control functions. For example, in a stage lighting system, the power supply and control functions of different types of lighting equipment (such as spotlights, follow spots, and color wash lights) can be integrated into different independent unit modules.

[0032] Wiring connector: At least one wiring connector is provided, corresponding to an independent unit module, and located inside the enclosure. The wiring connector plugs into the independent unit module, establishing an electrical connection between the independent unit module and the internal circuitry of the electrical box through this socket connection method. This design makes the installation and removal of the independent unit modules extremely convenient. When an independent unit module malfunctions, staff can quickly remove it from the electrical box for repair or replacement, significantly reducing maintenance time.

[0033] Main Controller: The main controller is fixedly installed inside the enclosure and is used to connect the independent unit modules and wiring terminals to achieve centralized control and data exchange of the independent unit modules. The main controller can receive control signals from the stage lighting control system and control each independent unit module according to these signals, realizing functions such as switching on and off the lighting equipment, adjusting brightness, and changing colors. At the same time, the main controller can also collect the working status information of each independent unit module and feed it back to the stage lighting control system, allowing staff to understand the operation of the electrical box in real time.

[0034] The enclosure features multiple air inlets on one side, with a cooling fan on the corresponding side. The air inlets and cooling fan work together to form a forced convection cooling channel. When the enclosure is operating, the cooling fan activates, drawing in cool outside air through the air inlets. This cool air circulates within the enclosure, carrying away the heat generated by the electrical components. The hot air is then expelled from the enclosure by the cooling fan, creating forced convection and effectively improving the enclosure's heat dissipation efficiency. This cooling structure ensures that the temperature of the electrical components remains within a reasonable range even during prolonged continuous operation, extending the lifespan of the components and improving the operational stability of the enclosure.

[0035] At least one circuit breaker is installed at one end of the pull-out frame, which controls the on / off state of the corresponding independent unit module. When operating an independent unit module on-site, staff can easily turn the module on or off using the circuit breaker without having to operate the entire electrical box, thus improving operational convenience and flexibility. For example, during a stage performance, if a lighting device malfunctions, staff can directly shut it off using the circuit breaker on the independent unit module, preventing disruption to the normal operation of other lighting equipment.

[0036] The socket connection methods between the connector and the independent unit module include, but are not limited to, direct-plug, spring-loaded, or snap-fit ​​connections. The connector and the independent unit module are electrically connected via conductive contacts or terminals. These different socket connection methods can be selected according to actual needs. Direct-plug connections are simple and convenient to operate, suitable for quick installation and disassembly; spring-loaded connections offer good contact stability, ensuring reliable electrical connections; snap-fit ​​connections provide strong fixation, preventing the independent unit module from loosening during use. Electrical connections via conductive contacts or terminals ensure stable current transmission, reduce contact resistance, and improve the operating efficiency of the electrical box.

[0037] II. Implementation Method:

[0038] (I) Example 1: Basic Application of Direct Plug-in Connection

[0039] In this embodiment, the connector and the independent unit module adopt a direct-plug connection structure, and the electrical connection is achieved through conductive contacts. The dimensions of the electrical box are designed according to the actual needs of the stage lighting equipment, using a standard 19U network cabinet specification, approximately 484cm long, 30-50cm deep, and 130-180cm high. The box has good strength and heat dissipation performance. Ten 5cm diameter air inlets are evenly distributed on one side of the box, and two 50W cooling fans are installed on the corresponding side.

[0040] In large-scale stage performances, stage lighting equipment is numerous and powerful, placing high demands on the stability of the electrical boxes. Spring-loaded plug-in structures ensure stable connections between individual unit modules and wiring terminals, reducing loosening issues caused by vibration and other factors. Touchscreen control allows staff to intuitively and conveniently manage the stage lighting equipment, enabling more complex lighting effects.

[0041] (II) Example 2: Application of snap-fit ​​connection to prevent loosening

[0042] In this embodiment, the wiring terminals and independent unit modules adopt a snap-fit ​​connection structure, and electrical connection is achieved through conductive contacts. The surface of the enclosure is treated with anti-corrosion to extend its service life. One side of the enclosure has 12 air inlets with a louvered design, which ensures ventilation while preventing dust from entering the enclosure. Two 60W cooling fans are installed on the corresponding side.

[0043] The electrical box contains 12 independent unit modules, each measuring 13cm in length, 2.8cm in width, and 12cm in height. The circuit breaker at one end of the pull-out frame features an indicator light, allowing staff to easily monitor the operational status of each unit module. The control switch on the outside of the box is wirelessly remote-controlled, allowing staff to operate the individual unit modules from anywhere on stage.

[0044] In highly mobile stage performances, the electrical control box may be subjected to significant vibration and impact. The snap-fit ​​connection structure effectively prevents individual unit modules from loosening during transportation and use, ensuring the normal operation of the electrical control box. Wireless remote control provides staff with a more flexible control method, allowing them to control the lighting equipment on stage at any time according to the performance needs, enhancing the interactivity and flexibility of the performance.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
