Description

Technical Field

[0001] This application relates to the field of electrical control equipment, and in particular to a lighting structure for an electrical control box. Background Technology

[0002] In industrial production, the electrical control box is the core component for controlling the operation of various machines, and its importance is self-evident. The electrical control box integrates a large number of electrical components, such as circuit breakers, contactors, relays, and circuit boards. Operators need to regularly inspect, debug, maintain, and set parameters for the components in the electrical control box to ensure that the machines can operate stably and safely.

[0003] However, existing electrical control boxes have a significant problem in practical use: insufficient lighting inside. Because electrical control boxes typically employ a closed or semi-closed design, their main purpose is to protect internal electrical components from external dust, moisture, and debris, while also reducing external electromagnetic interference. However, this design also makes it difficult for natural light to penetrate the box, and the lighting devices provided with the control box are often limited in brightness or cannot cover the entire operating area. This makes it difficult for operators to clearly see the status of various components, labels, and wiring connections inside the box.

[0004] Operating in poorly lit environments greatly increases the risk of operator errors. For example, switches might be accidentally switched to the wrong position, causing the machine to start, stop, or operate in an abnormal mode. Conversely, during wiring, the operator might not be able to see the wire colors and markings clearly, leading to incorrect connections and causing short circuits, open circuits, or other electrical faults. In severe cases, this could even damage electrical components inside the control box, causing machine downtime, disrupting the entire production process, and resulting in unnecessary economic losses for the company.

[0005] To address the issue of insufficient lighting inside the electrical control box, the common practice is to turn on the factory's main lights. However, this method has several drawbacks. Firstly, turning on the factory lights illuminates the entire factory, while only enough light is needed inside the control box. This results in wasted light, unnecessary power consumption, and fails to meet energy conservation and emission reduction requirements. Long-term use will significantly increase the company's electricity costs. Secondly, if operators only turn on the factory lights when they need to operate the control box, frequent switching is not only inconvenient but may also shorten the lifespan of the lighting fixtures.

[0006] Therefore, how to effectively solve the problem of insufficient lighting inside the electrical control box, provide operators with a clear and bright operating environment, avoid misoperation, and reduce energy consumption has become a technical problem that urgently needs to be solved in the field of electrical control equipment.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] This application provides a lighting structure for an electrical control box, which can solve the problem of how to improve the convenience of lighting inside the electrical control box and reduce lighting costs in the prior art.

[0010] (II) Technical Solution

[0011] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0012] An electrical control box lighting structure is provided, the electrical control box lighting structure comprising:

[0013] The enclosure is equipped with a sensor.

[0014] A door, which is movably disposed on the box body, for opening and closing the box body;

[0015] The light source assembly includes a light source disposed inside the housing and a power supply for powering the light source;

[0016] A proximity switch is fixedly installed on the door of the enclosure and faces the sensing part. The proximity switch is electrically connected between the light source and the power supply.

[0017] When the cabinet door is closed, the proximity switch contacts and disconnects from the sensing unit, thus breaking the circuit of the light source; when the cabinet door is opened, the light source is connected to the power supply and illuminates.

[0018] In some embodiments, the cabinet door includes a first cabinet door and a second cabinet door, which are rotatably connected to the cabinet body via a pivot and form a double-door structure.

[0019] In some embodiments, the enclosure is provided with light sources in areas opposite to the first and second doors, and the first and second doors are respectively provided with proximity switches electrically connected to the light sources.

[0020] In some embodiments, a pressure strip is provided on the side of the first door near the second door; when the door is closed, the second door presses against the pressure strip.

[0021] In some embodiments, a locking assembly is provided on the inner side of the first door, the locking assembly including a bolt retractably disposed on the first door, and the housing being provided with a pin hole adapted to the bolt; when the first door is closed, the bolt is inserted into the pin hole to fix the first door to the housing; the bolt is provided with a handle, the handle is provided with the proximity switch, and the housing being provided with a sensing part at the position opposite to the handle.

[0022] In some embodiments, a latch is rotatably provided on the inner side of the second door, and a keyhole for inserting a key into the latch is provided on the outer side; when the first door and the second door are closed, the latch rotates to the inner side of the first door to prevent the second door from opening.

[0023] In some embodiments, a single light source is provided and is located in the central region of the top of the housing.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0026] The lighting structure of the electrical control box in this application effectively solves the problem of insufficient light inside the electrical control box. When the operator needs to open the electrical control box, the door opens, and the proximity switch disconnects from the sensing part, connecting the light source to the power supply, and the light source immediately illuminates. This timely light source activation method provides sufficient light to the inside of the box the moment the operator opens the door, allowing the operator to clearly see the status, markings, and wiring connections of each electrical component inside the box. This creates a clear and bright operating environment for the operator, facilitating accurate operation and greatly reducing the probability of misoperation, effectively ensuring the normal operation of the machine and the safety of the electrical components inside the electrical control box. Compared to the traditional method of solving insufficient light inside the electrical control box, which often involves turning on the factory lighting, the lighting structure of the electrical control box in this application uses a proximity switch to control the on / off of the light source. When the box door is closed, the proximity switch contacts and disconnects from the sensing part, breaking the circuit of the light source and extinguishing it, thus consuming no power. The light source is only illuminated and powered when the box door is opened and operation is required. This method of automatically controlling the light source switch according to actual usage needs avoids the waste of electricity, effectively reduces energy consumption, meets the requirements of energy conservation and emission reduction, and also saves electricity costs for enterprises.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0042] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0044] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0045] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0046] The existing electrical control boxes suffer from insufficient lighting, and the current practice of turning on factory lights increases unnecessary power consumption, failing to meet energy conservation and emission reduction requirements, and will significantly increase the company's electricity costs in the long run. On the other hand, if operators only turn on the factory lights when they need to operate the electrical control box, frequent switching is not only inconvenient but may also shorten the lifespan of the lighting fixtures.

[0047] To address the aforementioned technical problems, this embodiment provides a lighting structure for an electrical control box.

[0048] Figure 1 This is a perspective view of the lighting structure of the electrical control box in an embodiment of this application. Figure 2 This is a front view of the lighting structure of the electrical control box in an embodiment of this application. Figure 3 This is a schematic diagram of the lighting structure of the electrical control box in an embodiment of this application. Figure 4 yes Figure 3 A schematic diagram of region A in the middle. Figure 5 This is a structural block diagram of the lighting structure of the electrical control box in the embodiments of this application.

[0049] See Figures 1 to 5 As shown, the lighting structure of the electrical control box in this embodiment includes: box body 1, box door 2, light source assembly, and proximity switch 5.

[0050] The enclosure 1 is equipped with a sensing element 11 adapted to the proximity switch 5. The sensing element 11 can be the inner wall of the enclosure 1. The interior of the enclosure 1 is used to integrate electrical components, such as circuit breakers, contactors, relays, circuit boards, etc.

[0051] The door 2 is movably mounted on the box body 1 and is used to open and close the box body 1.

[0052] The light source assembly includes a light source 3 disposed inside the housing 1 and a power supply 4 for supplying power to the light source 3. For example, the light source 3 is fixed to the inner wall of the housing 1 by screws or clips.

[0053] The proximity switch 5 is fixedly installed on the door 2 and faces the sensing part 11. The proximity switch 5 is electrically connected between the light source 3 and the power supply 4.

[0054] When the door 2 closes the enclosure 1, the proximity switch 5 contacts and disconnects from the sensing part 11, causing the light source 3 to be disconnected; when the door 2 opens the enclosure 1, the light source 3 is connected to the power supply 4 and lit.

[0055] like Figure 1 and Figure 3As shown, the aforementioned door 2 includes a first door 21 and a second door 22. The first door 21 and the second door 22 are rotatably connected to the housing 1 via a pivot, forming a double-door structure. Specifically, pivot mounting holes are provided at corresponding positions on the left and right sides of the housing 1. The pivot passes through the mounting holes and is fixed, allowing the first door 21 and the second door 22 to open and close freely around the pivot, facilitating operation and maintenance of the electrical control box by the operator.

[0056] like Figure 2 and Figure 3 As shown, furthermore, light sources 3 are respectively installed in the areas opposite to the positions of the first door 21 and the second door 22 in the enclosure 1. Proximity switches 5, electrically connected to the corresponding light sources 3, are respectively installed on the first door 21 and the second door 22. The light sources 3 are LED light strips, which have advantages such as high brightness, low energy consumption, and long lifespan. The LED light strips are fixed to the top plate 12 and side plates inside the enclosure 1 with screws to ensure secure installation. Each light source 3 is equipped with an independent power supply 4, which is a switching power supply capable of converting mains power into a stable voltage suitable for the operation of the LED light strip. Proximity switches 5, electrically connected to the corresponding light sources 3, are respectively installed on the first door 21 and the second door 22. The proximity switches 5 are capacitive proximity switches, characterized by high sensitivity and fast response speed. The proximity switches 5 are connected to the corresponding light source 3 and power supply 4 via wires, which are flame-retardant wires to ensure safe use. When the cabinet door 2 is opened, the proximity switch 5 separates from the sensing part 11 on the cabinet body 1, the circuit is turned on, and the light source 3 lights up; when the cabinet door 2 is closed, the proximity switch 5 contacts the sensing part 11, the circuit is turned off, and the light source 3 is turned off. The above settings enable the areas inside the cabinet body 1 corresponding to the first cabinet door 21 and the second cabinet door 22 to be independently illuminated, which can further reduce power consumption.

[0057] like Figure 1 and Figure 2 As shown, a pressure strip 211 is provided on the side of the first door 21 near the second door 22; when the door 2 closes the enclosure 1, the second door 22 presses against the pressure strip 211. The pressure strip 211 is integrally molded and fixed to the side wall of the first door 21. When the door 2 closes the enclosure 1, the second door 22 presses against the pressure strip 211, which serves as a buffer and seal, preventing dust, moisture, etc. from entering the electrical control box, and also reducing the noise when the door 2 closes. At the same time, the second door 22 pressing against the pressure strip 211 ensures that the first door 21 can only be opened when the second door 22 is opened.

[0058] like Figure 3 and Figure 4As shown, a locking assembly is further provided on the inner side of the first door 21. The pin 212 of the locking assembly is made of metal and has a certain strength and hardness. The pin 212 is telescopically mounted in the pin hole on the first door 21 via a spring 213. One end of the spring 213 is fixed to the pin 212, and the other end is fixed to the pin seat 214 on the inner wall of the first door 21. When the pin 212 is pressed, the spring 213 is compressed, and the pin 212 retracts into the first door 21; when the pin 212 is released, the spring 213 returns to its original state, and the pin 212 extends out of the first door 21. At the same time, a pin hole 13 adapted to the pin 212 is provided on the box body 1. The size and position of the pin hole 13 correspond to the pin 212. When the first door 21 is closed, the pin 212 is pressed to insert into the pin hole 13, thereby achieving a fixed connection between the first door 21 and the box body 1. A handle 215 is provided on the latch 212 for easy gripping by the operator. A proximity switch 5 is provided on the handle 215, which is connected to the corresponding sensor 11 on the housing 1 via a wire. When the operator grips the handle 215 and opens the first door 21, the proximity switch 5 separates from the sensor 11, and the light source 3 illuminates; when the first door 21 is closed, the proximity switch 5 contacts the sensor 11, and the light source 3 extinguishes. This design allows the light source 3 to be activated immediately in the area corresponding to the first door 21 inside the housing 1 when the operator opens the first door 21 using the latch 212, without having to fully open the first door 21 to activate the light source 3. This facilitates the operator's view of the area corresponding to the first door 21 from the area of ​​the second door 22 that is open on the housing 1.

[0059] like Figure 1 and Figure 3 As shown, a latch 221 is rotatably provided on the inner side of the second door 22, and a keyhole 222 is provided on the outer side for inserting a key into the latch 221. The shape and size of the keyhole 222 match the key. When both the first door 21 and the second door 22 are closed, inserting the key into the keyhole 222 and turning it causes the latch 221 to rotate to the inner side of the first door 21, thereby preventing the second door 22 from opening and providing a security function. Only by using the correct key can the latch 221 be opened and the second door 22 opened.

[0060] Figure 6 This is a schematic diagram of a light source being installed in the lighting structure of the electrical control box in an embodiment of this application.

[0061] like Figure 6As shown, in addition to the aforementioned double-door structure and multi-light source setup, a single-light source setup can also be used. Light source 3 is set as a single unit and installed in the center area of ​​the top of the enclosure 1. Light source 3 is also an LED light, fixed to the mounting bracket on the top of the enclosure 1 with screws. Power supply 4 uses the same switching power supply as in the multi-light source setup, providing a stable operating voltage for the LED light. A proximity switch 5 is installed on the enclosure door 2, connected to light source 3 and power supply 4 via wires. When enclosure door 2 is opened, proximity switch 5 separates from the sensing element 11, and light source 3 illuminates; when enclosure door 2 is closed, proximity switch 5 contacts the sensing element 11, and light source 3 extinguishes. This single-light source setup is simple in structure, low in cost, and suitable for electrical control boxes where lighting requirements are not particularly high.

[0062] In summary, the lighting structure of the electrical control box in this application effectively solves the problem of insufficient light inside the electrical control box. When the operator needs to open the electrical control box for operation, the box door 2 opens, at which point the proximity switch 5 separates from the sensing unit 11, connecting the light source 3 to the power supply 4, and the light source 3 immediately lights up. This timely light source activation method provides sufficient light to the inside of the box the moment the operator opens the box door 2, allowing the operator to clearly see the status, markings, and wiring connections of each electrical component inside the box. This creates a clear and bright operating environment for the operator, facilitating accurate operation and greatly reducing the probability of misoperation, effectively ensuring the normal operation of the machine and the safety of the electrical components inside the electrical control box. Compared to the traditional method of solving insufficient light inside the electrical control box, which often involves turning on the factory lighting, the lighting structure of the electrical control box in this application uses the proximity switch 5 to control the on / off state of the light source 3. When the box door 2 is closed, the proximity switch 5 contacts and disconnects from the sensing unit 11, causing the light source 3 to be disconnected and extinguished, consuming no power at this time; the light source 3 is only illuminated and powered when the box door 2 is opened for operation. This method of automatically controlling the switching of the light source 3 according to actual usage needs avoids the waste of electricity, effectively reduces energy consumption, meets the requirements of energy conservation and emission reduction, and also saves electricity costs for enterprises.
