Description

Technical Field

[0001] This utility model relates to the field of combiner cabinet technology, specifically to combiner cabinets. Background Technology

[0002] The junction box includes a cabinet, a support component, and electrical components. The support component is slidably connected to the cabinet, and the electrical components are located on the support component. The support component can drive the electrical components in and out of the cabinet.

[0003] However, during the transportation of the junction box, the R&D personnel discovered that the support components would slide relative to the cabinet, which would make the electrical components easy to slide relative to the cabinet, thus easily causing faults such as open circuits in the electrical components. Utility Model Content

[0012] In one embodiment, the first bolt includes a screw and a head connected to the screw, the screw having a first end and a second end, the head being connected to the first end, and the buffer portion being connected to the end side of the second end.

[0013] In one embodiment, the surface of the end side of the second end is provided as a spherical arc surface.

[0014] In one embodiment, the buffer portion covers at least a portion of the threads of the screw.

[0015] In one embodiment, the limiting member has a third end and a fourth end opposite to each other, the fourth end being tapered in the direction from the third end to the fourth end, and the fourth end being used to pass through the first slide rail and the second slide rail in the direction from the third end to the fourth end.

[0016] In one embodiment, the first slide rail is provided with a groove, and the second slide rail slides in cooperation with the groove. The groove has a bottom, an opening opposite to the bottom, and a sidewall connecting the two bottoms. The distance between the two sidewalls gradually decreases in the direction from the bottom to the opening.

[0017] In one embodiment, there are multiple limiting members, at least one of the limiting members is inserted through one sidewall of the groove, and at least another limiting member is inserted through another sidewall of the groove.

[0018] In one embodiment, when the limiting member passes through the first slide rail and the second slide rail, the supporting member is located inside the cabinet;

[0019] And / or, nano-graphite powder is provided between the first slide rail and the second slide rail;

[0020] And / or, the first slide rail and / or the second slide rail are made of polytetrafluoroethylene.

[0032] The beneficial effects of the embodiments of this utility model are as follows:

[0033] In this embodiment of the invention, the electrical components are mounted on a support, and the support can move the electrical components in and out of the cabinet via a slide rail assembly. When the electrical components need to be repaired, the operator can slide the support along with the electrical components out of the cabinet, freeing them from the limitations of the cabinet space. This allows for more direct and comprehensive access to all parts of the electrical components, eliminating the need to operate within the narrow cabinet, significantly reducing the difficulty of repairs and improving repair efficiency.

[0034] The limiting components in the slide rail assembly play a safety role. When the limiting components are installed on the first and second slide rails, they can restrict the relative sliding between them. At this time, the support component is stably fixed to the cabinet, thereby restricting the sliding of electrical components relative to the cabinet. During the normal operation of the combiner cabinet, this reduces the risk of electrical component connection loosening, open circuit, and other faults caused by accidental sliding, ensuring the safe operation of the equipment.

[0035] When it is necessary to move the support component, simply disengage at least one of the limiting components to achieve sliding. The operation is simple and controllable, reducing safety hazards during operation.

[0047] 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 skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0048] According to the first aspect of this application, referring to Figure 1 Also refer to Figures 4 to 7 This disclosure provides a junction box 100. The junction box 100 includes a cabinet 200, a support member 300, and a slide rail assembly 500. The support member 300 is used to support electrical components 400. The slide rail assembly 500 includes a first slide rail 510, a second slide rail 520, and a limiting member 530. The first slide rail 510 and the second slide rail 520 are slidably engaged. One of the first slide rail 510 and the second slide rail 520 is located in the cabinet 200, and the other is located in the support member 300. The support member 300 can drive the electrical component 400 to enter and exit the cabinet 200 through the slide rail assembly 500. When the limiting member 530 passes through the first slide rail 510 and the second slide rail 520, the limiting member 530 can restrict the relative sliding of the first slide rail 510 and the second slide rail 520. When the limiting member 530 disengages from at least one of the first slide rail 510 and the second slide rail 520, the first slide rail 510 and the second slide rail 520 can slide relative to each other.

[0049] Electrical component 400 is mounted on support component 300, and support component 300 can move electrical component 400 in and out of cabinet 200 via slide rail assembly 500. When electrical component 400 needs to be repaired, the operator can slide support component 300 along with electrical component 400 out of cabinet 200, freeing them from the space limitations of cabinet 200. This allows for more direct and comprehensive access to all parts of electrical component 400, eliminating the need to operate within the narrow interior of cabinet 200, significantly reducing repair difficulty and improving repair efficiency.

[0050] The limiting element 530 in the slide rail assembly 500 plays a safety role. When the limiting element 530 passes through the first slide rail 510 and the second slide rail 520, it can restrict the relative sliding between the two. At this time, the support element 300 is stably fixed to the cabinet 200, thereby restricting the sliding of the electrical component 400 relative to the cabinet 200. During the normal operation of the combiner cabinet 100, it reduces the risk of malfunctions such as loose connection or open circuit of the electrical component 400 caused by accidental sliding, and ensures the safe operation of the equipment.

[0051] When it is necessary to move the support 300, simply disengage the limiting member 530 from at least one of them to achieve sliding. The operation is simple and controllable, reducing safety hazards during operation.

[0052] The sliding engagement of the slide rail assembly 500 ensures smooth and stable movement of the support component 300, reducing vibration and impact on the electrical component 400 and helping to protect the performance and service life of the electrical component 400.

[0053] In some embodiments, at least one of the first slide rail 510 and the second slide rail 520 is threadedly engaged with the limiting member 530.

[0054] The threaded fit has a self-locking characteristic. When the limiting member 530 passes through and locks the first slide rail 510 and / or the second slide rail 520, it can effectively resist the influence of external forces such as vibration and impact, avoid accidental loosening of the limiting member, and ensure that the support member 300 and electrical component 400 are more reliably fixed in the cabinet 200.

[0055] The threaded engagement allows for easy locking and unlocking of the limiting component 530 through rotation, making operation simple and intuitive. Operators can precisely control the state of the limiting component 530 (locking or unlocking) simply by rotating it, without the need for complex tools. This facilitates quick switching between the fixed and sliding modes of the support component 300, improving efficiency during maintenance or adjustment.

[0056] In some embodiments, the limiting member 530 includes a first bolt 531 and a buffer portion 534. The buffer portion 534 is disposed on the periphery of the first bolt 531. When the limiting member 530 passes through the first slide rail 510 and the second slide rail 520, the buffer portion 534 is disposed on the first slide rail 510 and the second slide rail 520. The first bolt 531 is connected to the first slide rail 510 by threads.

[0057] The first bolt 531 is connected to the first slide rail 510 via threads, forming a rigid locking base to ensure the connection strength between the limiting member 530 and the first slide rail 510. At the same time, the buffer part 534 is respectively provided on the first slide rail 510 and the second slide rail 520, and further restricts the relative displacement of the two through physical contact, forming a dual limiting structure of rigid fixation and flexible filling, which greatly improves the stability of the locked state and reduces the risk of loosening during long-term use.

[0058] The buffer section 534 (usually made of rubber, elastic plastic or other materials) can absorb the vibration generated when the combiner cabinet 100 is working, and reduce the occurrence of collision between the first slide rail 510 and the second slide rail 520 due to vibration.

[0059] In some embodiments, the first bolt 531 includes a screw 533 and a head 532 connecting the screw 533. The screw 533 has a first end and a second end. The head 532 is connected to the first end, and the buffer portion 534 is connected to the end side of the second end.

[0060] During the process of the limiting member 530 passing through the first slide rail 510 and the second slide rail 520, it can prevent the second end from making hard contact with the first slide rail 510 and the second slide rail 520, thereby reducing the damage to the first slide rail 510 and the second slide rail 520.

[0061] The surface of the second end can have many shapes. In some embodiments, the surface of the second end is set as a spherical arc surface.

[0062] Thus, the second end can provide guidance for the first bolt 531 to pass through the first slide rail 510 and the second slide rail 520, so that the first bolt 531 can pass through the first slide rail 510 and the second slide rail 520.

[0063] However, this design is not limited to this. In some other embodiments, the end surface of the second end is conical.

[0064] In some embodiments, the buffer portion 534 covers at least a portion of the threads of the screw 533. In this way, the buffer portion 534 is more securely connected to the screw 533.

[0065] However, this design is not limited to this. In some other embodiments, the buffer portion 534 covers the unthreaded portion of the screw 533.

[0066] In some embodiments, the limiting member 530 has a third end and a fourth end opposite to each other. The fourth end is tapered in the direction from the third end to the fourth end and is used to pass through the first slide rail 510 and the second slide rail 520 in the direction from the third end to the fourth end.

[0067] The tapered end of the limiting member 530 provides guidance during its insertion into the first slide rail 510 and the second slide rail 520. This allows for quick alignment of the limiting member 530 with the mating holes of the first and second slide rails, reducing alignment difficulty. Especially when there are slight deviations in the hole positions of the first and second slide rails 510, the tapered structure can automatically correct its position through the inclined guide, allowing the limiting member 530 to insert smoothly, reducing operational complexity and improving locking efficiency.

[0068] In some embodiments, the first slide rail 510 is provided with a slide groove 511, and the second slide rail 520 slides in cooperation with the slide groove 511. The slide groove 511 has a groove bottom 512, a groove opening 513 opposite to the groove bottom 512, and a groove sidewall 514 connecting the two groove bottoms 512. In the direction from the groove bottom 512 to the groove opening 513, the distance between the two groove sidewalls 514 gradually decreases.

[0069] The inclined groove sidewall 514 of the slide 511 provides lateral constraint to the second slide rail 520. During the sliding process, the two sides of the second slide rail 520 will always maintain a close contact with the inclined groove sidewall 514. Even if subjected to slight vibration or external impact, the lateral displacement of the second slide rail 520 can be limited by the inclination angle of the groove sidewall 514, ensuring accurate and stable sliding trajectory.

[0070] The inclined groove sidewall 514 can convert part of the vertical load (such as the gravity of the electrical component 400) transmitted by the second slide rail 520 into a component force along the sidewall direction, making the force distribution more uniform and avoiding stress concentration at local positions at the groove bottom 512 or groove opening 513.

[0071] In some embodiments, multiple limiting members 530 are provided, with at least one limiting member 530 passing through one groove sidewall 514 and at least another limiting member 530 passing through another groove sidewall 514. This makes the limiting member 530 more evenly stressed, which helps to extend the service life of the limiting member 530.

[0072] In some embodiments, when the limiting member 530 passes through the first slide rail 510 and the second slide rail 520, the supporting member 300 is located inside the cabinet 200.

[0073] When the limiting member 530 is installed and fixed, the supporting member 300 is inside the cabinet 200 (rather than partially protruding), which means that the electrical component 400 is also completely inside the cabinet 200. In this state, the gap between the electrical component 400 and the cabinet 200 is more controllable, which can minimize the risk of collision between the electrical component 400 and the cabinet 200 during transportation bumps and improve the safety of the transport junction box 100.

[0074] In some embodiments, nano-graphite powder is provided between the first slide rail 510 and the second slide rail 520.

[0075] Nano-graphite powder possesses excellent lubricating properties. Its layered structure can form a stable lubricating film between the contact surfaces of the slide rails, significantly reducing the sliding friction between the first slide rail 510 and the second slide rail 520. When the support component 300 drives the electrical component 400 in and out of the cabinet 200, the nano-graphite powder effectively reduces the direct friction between the two, making the sliding process smoother and more stable, avoiding jamming, reducing the force required for the operator to push the support component 300, and improving operational convenience.

[0076] The nano-sized graphite powder particles are fine and uniformly distributed, which can fill the tiny pits and scratches on the contact surface of the slide rail, reducing friction and wear caused by surface unevenness. At the same time, the graphite powder itself has good high temperature resistance and chemical stability, which can maintain the lubrication effect during long-term friction, preventing the slide rail from excessive wear, overheating or even seizing due to dry friction, and significantly extending the service life of the first slide rail 510 and the second slide rail 520.

[0077] The lubrication performance of nano-graphite powder is minimally affected by temperature, maintaining stable lubrication effects in both high and low temperature environments. Whether in high-temperature, sun-exposed outdoor scenarios or low-temperature, frigid environments, it effectively ensures the reliability of the slide rail assembly 500 under various operating conditions, thus broadening the applicable environmental range of the combiner cabinet 100.

[0078] The thin film formed by nano-graphite powder on the surface of the slide rail can play a certain role in isolation, reducing the direct contact between moisture and corrosive gases in the air and the metal surface of the slide rail, thus reducing the risk of rust. At the same time, the graphite powder can also adsorb some of the tiny dust particles that have invaded the gaps between the slide rails, preventing dust from causing abrasive damage to the slide rail surface during sliding.

[0079] Nano-graphite powder provides long-lasting lubrication and is less prone to leakage. Compared to traditional lubricating oils, it eliminates the need for frequent additions or replacements, reducing the maintenance frequency and cost of the slide rail assembly 500. Furthermore, its solid form avoids the leakage and contamination of internal electrical components 400 that can occur with liquid lubricating oils, making it more suitable for the clean operation requirements of the combiner cabinet 100.

[0080] In some embodiments, the first slide rail 510 and / or the second slide rail 520 are configured to be made of polytetrafluoroethylene.

[0081] Polytetrafluoroethylene (PTFE) has a low coefficient of friction and its surface has a self-lubricating effect. When at least one of the first slide rail 510 and the second slide rail 520 is made of PTFE, the friction between them during relative sliding is greatly reduced, making the process of the support component 300 driving the electrical component 400 in and out of the cabinet 200 easier and smoother, reducing the manpower required for operation.

[0082] At the same time, its self-lubricating properties reduce the reliance on additional lubricants, maintaining good sliding performance even when lubricant is insufficient, thus reducing maintenance requirements.

[0083] Polytetrafluoroethylene (PTFE) has excellent wear resistance and extremely strong chemical stability. It can withstand the erosion of various corrosive media such as acids, alkalis, and organic solvents. At the same time, it is resistant to ultraviolet rays, high and low temperatures, and is not easily aged, embrittled, or degraded due to environmental factors.

[0084] This makes the surface of the first slide rail 510 and / or the second slide rail 520 less prone to wear and cracking due to friction, corrosion or temperature changes during long-term use, thus greatly extending the service life of the first slide rail 510 and / or the second slide rail 520.

[0085] The surface of polytetrafluoroethylene (PTFE) has extremely strong non-stick properties, making it difficult for contaminants such as dust, moisture, and oil to adhere to it. This means that the surfaces of the first slide rail 510 and / or the second slide rail 520 are less prone to sliding jams due to the accumulation of contaminants, reducing the risk of malfunctions caused by untimely cleaning. It is especially suitable for dusty and humid environments, reducing the frequency and difficulty of daily maintenance.

[0086] Polytetrafluoroethylene (PTFE) is an excellent insulating material with extremely high volume resistivity. Using it as the material for the first slide rail 510 and / or the second slide rail 520 can prevent the first slide rail 510 and / or the second slide rail 520 from becoming part of the electrical circuit, reducing safety hazards such as short circuits and electric shocks caused by accidental conduction of the first slide rail 510 and / or the second slide rail 520.

[0087] Polytetrafluoroethylene (PTFE) maintains stable physical properties over an extremely wide temperature range, exhibiting resistance to both extreme cold and high temperatures. It will not soften or deform at high temperatures, nor will it become brittle or crack at low temperatures, ensuring the structural stability of the first slide rail 510 and / or the second slide rail 520 under varying climatic conditions or temperature fluctuations within the cabinet 200, thus guaranteeing the reliability of the sliding function.

[0088] Polytetrafluoroethylene (PTFE) has a certain degree of elasticity and flexibility. During sliding, it can absorb some vibration energy, reduce noise caused by friction or collision, make the movement of the support 300 quieter, and improve the operating environment.

[0089] In some embodiments, the slide rail assembly 500 includes a plurality of limiting members 530, which are used for mounting and dismounting to the first slide rail 510 and the second slide rail 520.

[0090] Even if one of the limiters 530 becomes loose or damaged due to an accident, the remaining limiters 530 can still maintain their locking function, forming redundant protection to prevent the support 300 from suddenly sliding due to a single point of failure, thus protecting the electrical components 400 and the safety of the operators.

[0091] In some embodiments, multiple slide rail assemblies 500 are provided, and multiple slide rail assemblies 500 connect the support member 300 and the cabinet 200.

[0092] Multiple slide rail assemblies 500 can share the weight of the support component 300 and the electrical component 400, so that the load is evenly distributed to different positions of the cabinet 200, avoiding problems such as deformation and accelerated wear of a single slide rail assembly 500 due to excessive force.

[0093] In some embodiments, the electrical component 400 is fixedly connected to the support component 300.

[0094] When the support component 300 drives the electrical component 400 in and out of the cabinet 200 through the slide rail assembly 500, the fixed connection between the electrical component 400 and the support component 300 can ensure that the two move synchronously, and prevent the electrical component 400 from sliding off the support component 300, tipping over or colliding with the internal structure of the cabinet 200 due to inertia during the sliding process.

[0095] In some embodiments, the electrical component 400 is detachably connected to the support component 300.

[0096] In this way, when electrical component 400 is damaged, it can be removed from support component 300 and replaced, avoiding the need to replace the undamaged support component 300 as well. This helps save on maintenance costs.

[0097] In some embodiments, the support 300 is configured as a pallet.

[0098] The edge of the tray is equipped with a baffle or folded edge of a certain height, which can laterally limit the electrical components 400 and prevent them from slipping off the edge of the tray when sliding or the junction box 100 shakes, thus further improving safety.

[0099] In some embodiments, the slide rail assembly 500 is detachably connected to the cabinet 200.

[0100] As the core component for the sliding of the support 300, the slide rail assembly 500 may experience functional impairment due to wear, deformation, or failure of the limiting component 530 after prolonged use. The detachable connection allows operators to directly remove the slide rail assembly 500 from the cabinet 200, enabling individual inspection or replacement without destructive disassembly of the cabinet 200. For example, if the slide groove 511 of the first slide rail 510 deforms due to long-term friction, the entire slide rail assembly 500 can be removed and replaced with a new one, preventing the entire cabinet 200 from being rendered unusable due to a partial failure, significantly reducing maintenance costs and downtime.

[0101] In some embodiments, the cabinet 200 is provided with an inlet and outlet 212, and the electrical component 400 can enter and exit the inlet and outlet 212 through the slide rail assembly 500. The electrical component 400 is provided with a connector 440 on the side near the inlet and outlet 212.

[0102] When connector 440 is exposed near inlet / outlet 212, the operator has a clearer view and can directly observe the condition of the connector pins and interface (such as whether there is oxidation, deformation, or foreign matter), which facilitates accurate alignment and insertion, and reduces connector damage caused by blind insertion.

[0103] In some embodiments, multiple electrical components 400 are provided, and the multiple electrical components 400 are provided on the support member 300. In this way, the support member can support multiple electrical components 400.

[0104] In some embodiments, electrical component 400 is configured as a UPS power supply 410, a switch, a voltage regulator 410, a fuse, or an AC power distribution circuit module.

[0105] In some embodiments, the support member 300 is provided with reinforcing ribs 310.

[0106] The reinforcing ribs 310 (usually strip-shaped, grid-shaped, or zigzag-shaped structures protruding along the surface of the support 300) can significantly improve the bending and torsional resistance of the support 300 by dispersing stress. When the support 300 supports multiple or heavy electrical components 400, the reinforcing ribs 310 can effectively resist deformations such as sagging in the middle and warping at the edges caused by gravity, ensuring that the support 300 always maintains a flat bearing surface.

[0107] In some embodiments, the first slide rail 510 is disposed on the cabinet 200, the second slide rail 520 is disposed on the support member 300, the reinforcing rib 310 is disposed opposite to the second slide rail 520, and the extending direction of the second slide rail 520 intersects the extending direction of the reinforcing rib 310.

[0108] If the reinforcing rib 310 extends parallel to the second slide rail 520, it can only enhance the strength in one direction, requiring more material to cover the multi-directional force requirements; while the cross layout can form an "all-round support network" with less material, which can improve the overall strength of the support 300 while avoiding the increase in the weight of the support 300 due to excessive increase in the number or thickness of the reinforcing ribs 310.

[0109] Reference Figures 1 to 3 This disclosure provides a combiner cabinet 100. The combiner cabinet 100 includes a cabinet 200 and a power supply 410. The power supply 410 includes a protective shell 420 and a battery pack 430. The protective shell 420 is disposed inside the cabinet 200 and has a first receiving cavity 421. The battery pack 430 is disposed inside the first receiving cavity 421 and includes wires and multiple batteries 431. Each battery 431 has a terminal block 432, and the multiple terminals block 432 are connected by wires.

[0110] The protective casing 420 physically isolates the wiring terminals 432 of the battery 431 from other electronic components inside the cabinet 200, preventing short circuits caused by accidental contact between the wiring terminals 432 and electronic components inside the cabinet 200. Short circuits may cause the battery 431 to overheat, catch fire, or even explode. The protective casing 420 structurally blocks this risk, significantly improving the operational safety of the combiner cabinet 100.

[0111] The protective casing 420 can reduce the corrosion of the battery pack 430 (especially the terminal block 432 and wire connection points) by external dust, moisture and other impurities.

[0112] The protective shell 420 integrates the battery pack 430 into a separate first receiving cavity 421, making the component layout inside the cabinet 200 more organized. The previously exposed battery pack 430 and wiring terminals 432 may have led to messy wiring inside the cabinet 200, but the protective shell 420 can centrally store this part of the structure, making it easier for subsequent inspection, maintenance and wiring organization.

[0113] In one embodiment, the power supply 410 further includes a UPS (Uninterruptible Power Supply) circuit board 433, which is electrically connected to the battery pack 430.

[0114] The function of UPS circuit board 433 is to quickly switch to battery pack 430 power supply mode when the external mains power is interrupted, so as to ensure the continuous operation of combiner cabinet 100 and related equipment.

[0115] In one embodiment, the UPS circuit board 433 is disposed within the first receiving cavity 421.

[0116] The protective casing 420 houses the battery pack 430 (including terminals 432 and wires) and the UPS circuit board 433 within the first receiving cavity 421, physically isolating these two components from other electronic components inside the cabinet 200. Neither the conductive parts of the battery pack 430 (terminals 432 and wires) nor the UPS circuit board 433 are prone to accidental contact with external components, thus reducing the risk of short circuits and leakage and significantly improving safety.

[0117] The protective casing 420 can reduce the corrosion of the UPS circuit board 433 by external dust, moisture and other impurities.

[0118] In one embodiment, the cabinet 200 includes a cabinet body 210 and a door 220. The cabinet body 210 is provided with a second receiving cavity 211 and an inlet / outlet 212 communicating with the second receiving cavity 211. The door 220 is movably disposed in the cabinet 200 and is used to control the opening and closing of the inlet / outlet 212. The power supply 410 can enter and exit the second receiving cavity 211 through the inlet / outlet 212.

[0119] After the door 220 is opened, the power supply 410 can freely enter and exit the second receiving cavity 211 through the inlet and outlet 212, which facilitates the initial installation, later replacement or overall debugging of the power supply 410.

[0120] The second receiving cavity 211 and the door 220 of the cabinet body 210 form the outer protection of the junction box 100, forming a double protection structure with the protective shell 420 of the power supply 410 itself. The protective shell 420 isolates the power supply 410, while the second receiving cavity 211 and the door 220 isolate the external environment (such as dust, water vapor, collision with foreign objects, and accidental touch by personnel) of the cabinet body 200 from the outside, further reducing the interference and damage of external factors to the power supply 410.

[0121] When the door 220 is closed, the power supply 410 module can be sealed inside the second receiving cavity 211 to prevent personnel or external objects from accidentally coming into contact with the power supply 410 in a non-maintenance state. Even though the protective shell 420 has provided internal isolation, the door 220 can still add a safety barrier and reduce safety hazards.

[0122] In one embodiment, the power supply 410 further includes a connector 440 passing through the protective housing 420, through which the battery pack 430 can transmit electrical energy to components outside the first receiving cavity 421.

[0123] The connector 440 serves as the power transmission interface on the protective housing 420, avoiding the problem of having too many or too large holes in the protective housing 420 to lead out wires, thus improving the sealing performance of the protective housing 420. This allows the battery pack 430 inside the first receiving cavity 421 to remain in a relatively sealed protective environment, maintaining the physical isolation and environmental protection function of the protective housing 420 for internal components (such as preventing dust and moisture from entering).

[0124] In one embodiment, when the door 220 opens the inlet / outlet 212 and the power supply 410 is located in the second receiving cavity 211, the connector 440 is exposed at the inlet / outlet 212.

[0125] The inlet / outlet 212 provides an open operating space for the connector 440, allowing maintenance personnel to directly observe the connection status of the connector 440 (such as whether it is tightly inserted or whether it is damaged) through the inlet / outlet 212, reducing misoperation caused by obstructed vision or narrow space (such as inserting the wrong interface or damaging the connector 440 due to improper force).

[0126] In one embodiment, the inlet / outlet 212 is located on the periphery of the cabinet body 210.

[0127] The periphery of the cabinet body 210 (such as the sides, front, and back) is the area most easily accessed by personnel when operating the combiner cabinet 100. The entrance and exit 212 are set here so that the opening and closing of the door 220 and the entry and exit of the power supply module 410 can be completed within the natural range of human movement.

[0128] In one embodiment, the junction box 100 further includes a support member 300 slidably connected to the cabinet body 200, and the power supply 410 is disposed on the support member 300. The support member 300 can drive the power supply 410 to enter and exit the second receiving cavity 211 through the inlet and outlet 212.

[0129] When the support 300 drives the power supply 410 to slide out of the second receiving cavity 211 (partially or completely exposing the inlet and outlet 212), the power supply 410 module can be placed in an open area outside the cabinet 200. At this time, the power supply 410 is in a state where it is not obstructed by the cabinet 200, and maintenance personnel can contact the power supply 410 from multiple directions, reducing the physical restrictions when operating in the narrow space inside the cabinet 200.

[0130] In one embodiment, the power supply 410 is fixedly connected to the support 300.

[0131] When the support 300 drives the power supply 410 in and out of the cabinet 200, the fixed connection between the power supply 410 and the support 300 ensures that the two move synchronously, preventing the power supply 410 from sliding off the support 300, tipping over, or colliding with the internal structure of the cabinet 200 due to inertia during the sliding process.

[0132] The power supply 410 is detachably connected to the support 300.

[0133] In this way, when the power supply 410 fails, it can be removed from the support 300 and replaced, avoiding the need to replace the undamaged support 300 as well. This helps save on maintenance costs.

[0134] In one embodiment, the power supply 410 has multiple power supplies 410 located within the cabinet 200. This way, if one power supply 410 fails, another power supply 410 can continue to operate.

[0135] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
