Description

Technical Field

[0001] This application relates to the field of sheet metal housing technology, and in particular to a distribution box housing. Background Technology

[0002] A distribution box is a low-voltage power distribution device that assembles switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. Its structure is generally box-type or cabinet-type. The distribution cabinet contains a large number of complex electrical components. With the advancement of technology, the requirements for distribution boxes are also getting higher and higher. They must ensure convenient internal installation and wiring, as well as heat dissipation.

[0003] For example, Chinese patent with authorization announcement number CN220754108U and publication date of April 9, 2024 discloses a low-voltage distribution cabinet housing that facilitates wire bundling, including a cabinet body and an L-shaped hanging rod. A mounting base is provided on one side of the inner wall of the cabinet body, and a rotating rod is provided on one side of the mounting base. An I-beam roller is provided on the outside of the rotating rod, and a rocker arm is provided on one side of the I-beam roller. A load-bearing support is installed on the other side of the inner wall of the cabinet body, and a groove is fixed inside the load-bearing support. The L-shaped hanging rod is located outside the groove.

[0004] The aforementioned device, by installing I-beam rollers inside the enclosure, can tighten the wires, preventing them from becoming tangled. Simultaneously, the device can absorb moisture inside the enclosure, ensuring the dryness of the equipment surface and extending the lifespan of the equipment inside. Regarding the aforementioned technology, the inventor believes that while this application can store wires, the narrow space inside the enclosure makes wire winding inconvenient. Therefore, a new type of distribution box enclosure that facilitates wire management is needed. Utility Model Content

Both the instrument mounting plate and the wiring mounting plate are movably connected to the box body. The instrument mounting plate is horizontally installed and is snapped into the box body. The side of the instrument mounting plate is provided with a notch for wire threading. The wiring mounting plate is vertically installed and is hung in the box body. The wiring mounting plate is provided with a wire threading groove. A cooling fan is provided at the bottom of the box body. Multiple ventilation holes are provided on the side of the box body.

[0008] Preferably, a fixing plate is provided at the four inner corners of the upper part of the housing. The fixing plate is an "L" shaped plate. The instrument mounting plate is a square plate and can be tilted and placed between the top of the housing and the fixing plate. The notch is provided on the left, right and rear sides of the instrument mounting plate. Multiple wire holes are provided on the instrument mounting plate, and the position of the wire holes corresponds to the instrument installation position.

[0009] Preferably, the enclosure is provided with a fixing plate, which is connected to the enclosure by bolts and the cross-sectional view of the fixing plate is U-shaped. The wiring mounting plate is a square plate and the edge of the wiring mounting plate is provided with a bent support part. The support part is an L-shaped plate and is engaged with the fixing plate.

[0010] Preferably, the lower side of the circuit mounting plate is provided with bolt holes and is fixed to the enclosure through the bolt holes.

[0011] Preferably, the circuit mounting plate has multiple L-shaped bending pieces with different directions on the back, and the inner side of the end of the L-shaped bending piece has a protrusion.

[0012] Preferably, the upper part of the lid is provided with a transparent observation window, and the middle part of the lid is provided with a latch.

[0013] Preferably, the top of the box is provided with a lifting ring, which is detachably connected to the box.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. This application, by providing movable instrument mounting plates and wiring mounting plates inside the enclosure, allows for the pre-installation of instruments and wiring on the instrument mounting plates and wiring mounting plates before installation into the enclosure, facilitating wiring installation. Furthermore, by providing notches on the instrument mounting plates and wiring grooves on the wiring mounting plates, wiring can be easily threaded through, simplifying installation. Finally, by providing a cooling fan at the bottom of the enclosure and ventilation holes on the sides, heat dissipation efficiency can be improved, ensuring stable operation of the components inside the enclosure.

[0016] 2. By setting "L"-shaped fixing plates at the four corners of the inner side of the enclosure, the instrument mounting plate can be supported for easy installation. At the same time, notches are set on the left, right and rear sides of the instrument mounting plate to facilitate the passage of wires. By setting "U"-shaped fixing plates inside the enclosure and setting bent support parts on the edge of the wiring mounting plate, the support parts can be snapped into the fixing plates for easy installation. By setting bolt holes on the lower side of the wiring mounting plate, the wiring mounting plate can be locked and fixed through the bolt holes to ensure the stable connection of the wiring mounting plate. By setting multiple L-shaped bending pieces in different directions on the back of the wiring mounting plate, the cable can be passed through the cable tray and fixed, ensuring the cable bundling effect and facilitating installation.

[0017] 3. By installing detachable lifting rings on the top of the container, lifting and transportation are convenient, and the lifting rings can be reused to reduce resource waste. Attached Figure Description
