Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to a switch box for silent generator sets that facilitates multi-load connection. Background Technology

[0002] Silent generator sets are widely used in hospitals, hotels, residential areas, and other places with strict noise requirements due to their low noise characteristics. Traditional silent generator set switch boxes typically offer only a limited number of standard terminals (such as one or two) and have limited space. In practical applications, it is often necessary to connect multiple load cables or to connect cables of different diameters and types (such as ordinary copper lugs, OT terminals, and directly fixed cables) to the same switch. Existing technology has the following drawbacks: 1. Wiring difficulties: Due to the limited number of terminal interfaces on the switch and space constraints, it is difficult to connect multiple cables; 2. Poor compatibility: The switch terminal specifications are fixed, which makes it difficult to adapt to non-standard or special cable connectors, requiring additional adapters, increasing costs and potential points of failure. 3. Operational hazards: If it is necessary to add or replace the load, the operator must open the enclosure and operate directly on the live switch terminals in a narrow space, which poses a high risk of electric shock and is a cumbersome process. 4. Affects sealing performance: Frequent opening and closing of the enclosure for wiring operations may damage the enclosure's sealing structure, which will affect its waterproof performance in the long run.

[0003] Therefore, there is an urgent need for a switch box that is simple to wire, safe to operate, more compatible, and easy to connect to multiple loads to solve the above problems. Utility Model Content

[0004] This invention aims to solve the technical problems existing in the prior art. Therefore, this invention provides a switch box for silent generator sets that is simple to wire, safe to operate, and has better compatibility, facilitating multi-load connection.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A switch box for use with silent generator sets, facilitating multi-load connection, is provided. It includes a cabinet, an output switch fixedly mounted on the back panel of the cabinet, and a door on the front panel for operating the output switch. Inside the cabinet, below the output switch, a wiring compartment is separated by an inverted L-shaped partition. A connecting opening is provided on the vertical plate of the L-shaped partition, and an insulating plate is fixedly mounted on the connecting opening. Each terminal of the input end of the output switch is connected to a vertical copper busbar, which extends to the insulating plate. A horizontal connecting copper busbar is fixedly mounted on each of the copper busbars, with the other end of the connecting copper busbar extending through the insulating plate into the wiring compartment, and having at least two wiring holes at that end.

[0006] In some alternative embodiments, one end of the connecting copper busbar is provided with a bent portion, and the bent portion and the lead-out copper busbar are fixed together to the insulating plate by bolts.

[0007] In some alternative implementations, the connecting copper busbars are arranged in a straight line.

[0008] In some alternative implementations, two adjacent connecting copper busbars are staggered vertically.

[0009] In some alternative embodiments, the wiring hole is a round hole or an oblong hole or a combination of both, and the load cable is fixed to the wiring hole by bolts.

[0010] In some alternative implementations, the wiring hole is a screw hole, and the load cable is fixed to the wiring hole by a screw.

[0011] In some alternative embodiments, the back panel of the enclosure has an operating opening opposite the insulating board, and a cover plate is detachably installed on the operating opening.

[0012] In some alternative embodiments, a protective door made of transparent plexiglass is hinged to the wiring compartment.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes lead-out copper busbars and connecting copper busbars to lead each terminal on the output switch to the wiring chamber and expand it into multiple wiring holes. This not only provides ample wiring space but also greatly increases the number of load cables that can be connected. At the same time, it can easily accommodate various wiring methods such as crimped copper lugs, OT terminals, and even direct use of cable lugs with bolt crimping, without being limited by the original switch terminal specifications. 2. All wiring operations are performed away from the output switch, and when adding or replacing load lines, there is no need to operate the output switch. Simply connect the wires to the connecting copper busbar. This simplifies the process, improves work efficiency, and reduces the need for frequent in-depth operations inside the enclosure. It also helps protect the enclosure's sealing integrity, extends its service life, and enhances its waterproof performance. Attached Figure Description

[0021] As attached Figure 3 and attached Figure 4 As shown, the L-shaped partition 3 has a connecting opening 3.1 on its vertical plate, and an insulating plate 6 is fixedly installed on the connecting opening 3.1; each terminal of the input end of the output switch 2 is connected to a vertical lead-out copper busbar 4, and the lead-out copper busbar 4 extends to the insulating plate 6; a horizontal connecting copper busbar 5 is fixedly installed on each of the lead-out copper busbars 4, as shown in the attached figure. Figure 3 As shown, the connecting copper busbars 5 in this embodiment are arranged in a straight line. The other end of the connecting copper busbar 5 extends through the insulating plate 6 into the wiring chamber, and at least two wiring holes 5.1 are provided on this end.

[0022] In one embodiment, the wiring hole 5.1 can be a round hole, an oblong hole, or a combination of both, and the load cable is fixed to the wiring hole 5.1 by bolts 7. The oblong hole design allows for adjustment of the bolt position within a certain range to accommodate cable connectors of different sizes.

[0023] In another embodiment, the wiring hole 5.1 is a screw hole, and the load cable is fixed to the wiring hole by a screw.

[0024] This embodiment utilizes lead-out copper busbars and connecting copper busbars to lead each terminal on the output switch to the wiring chamber and expand it into multiple wiring holes. This not only provides ample wiring space but also greatly increases the number of load cables that can be connected. It also easily accommodates various wiring methods such as crimped copper lugs, OT terminals, and even direct use of cable lugs with bolts, without being limited by the original switch terminal specifications. Furthermore, all wiring operations are performed away from the output switch, and when adding or replacing load lines, there is no need to operate the output switch; only wiring on the connecting copper busbars is required. This simplifies the process, improves work efficiency, and reduces the necessity of frequent in-depth operations inside the enclosure. It also helps protect the enclosure's sealing integrity, extends its service life, and enhances its waterproof performance.

[0025] Preferably, in this embodiment, the connecting copper busbar 5 and the lead-out copper busbar 4 are fixed in the following way: one end of the connecting copper busbar 5 is provided with a bent part 5.2, and the bent part 5.2 and the lead-out copper busbar 4 are fixed together on the insulating plate 6 by bolts 7.

[0026] Preferably, in this embodiment, an operation port 1.4 is provided on the back plate of the housing 1, directly opposite the insulating plate 6. A cover plate 1.5 is detachably installed on the operation port 1.4 to facilitate the installation of copper busbars and connecting copper busbars.

The protective door 1.6 is made of transparent plexiglass, which facilitates quick inspection of the connection status for any abnormalities (such as looseness or burn marks). Example

[0028] The only difference between this embodiment and implementation one is the arrangement of the connecting copper busbars. In this embodiment, two adjacent connecting copper busbars 5 are arranged alternately (not shown in the figure), which can increase the wiring space of each connecting copper busbar and facilitate operation.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
