Description

Power distribution plate

Technical Field

The present invention relates to a power distribution board, and more particularly, to a power distribution board with selectable output voltage.

Background

Power distribution boards are widely used in power distribution systems, the primary purpose being to distribute electrical energy from an input power source to a load through a circuit breaker. The power distribution tray typically contains a plurality of circuit breakers, and a plurality of brackets for mounting the circuit breakers. Each cradle is electrically connected to an input bus that is electrically connected to the same input power source to provide a specific voltage to the circuit breaker that is assembled to the cradle. Under normal conditions, the power received by the circuit breaker is transmitted to the load after the circuit breaker is conducted. Upon occurrence of an overcurrent condition, the circuit breaker automatically opens to cut off an electrical connection path between the load and the input power.

However, in the case that the input buses are all connected to the same input power source, the plurality of loads can only receive the same voltage from the power distribution panel, that is, the corresponding voltage cannot be provided according to the actual requirements of different loads, so that the application flexibility is low.

Therefore, how to develop a power distribution plate capable of improving the above-mentioned known technology is an urgent need.

Disclosure of Invention

The invention aims to provide a power distribution disc, which is provided with two input buses, wherein the two input buses are respectively coupled with two power supplies. The power distribution plate is provided with a breaker module, comprises a breaker and an adapter, and is electrically connected to one of the input buses through the adapter assembled with the breaker; and when the circuit breaker is not assembled to the adapter (i.e., the adapter is removed from the circuit breaker), the circuit breaker is electrically connected to the other input bus. Therefore, the circuit breaker can be selectively coupled to one of the two input buses through the connection of the adapter or not, and the power distribution plate can provide two different output voltages, so that the flexibility of the application is improved.

In order to achieve the above object, the present invention provides a power distribution board, which includes a first input bus, a second input bus, a plurality of brackets, and a plurality of circuit breaker modules. The first input bus and the second input bus are respectively coupled to the first power supply and the second power supply. The plurality of brackets are electrically connected to the first input bus or the second input bus. The breaker modules are respectively assembled to the brackets. Each circuit breaker module comprises a circuit breaker and an adapter, and the adapter is detachably assembled with the circuit breaker. In any of the circuit breaker modules and their corresponding assembled brackets, the circuit breaker is electrically connected to the first input bus when the adapter is not assembled to the circuit breaker, and the circuit breaker is electrically connected to the second input bus when the adapter is assembled to the circuit breaker.

Detailed Description

Some exemplary embodiments embodying features and advantages of the present invention will be described in detail in the following description. It will be understood that the invention is capable of various modifications in various aspects, all without departing from the scope of the invention, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the invention.

Fig. 1 is a schematic perspective view of a power distribution plate according to a preferred embodiment of the present invention. Fig. 2A and 2B are schematic cross-sectional views of the power distribution plate of fig. 1 along sections AA and BB, respectively. As shown in fig. 1, 2A and 2B, the power distribution panel includes a first input bus 1, a second input bus 2, a plurality of brackets 3, and a plurality of circuit breaker modules 4. The first input bus 1 and the second input bus 2 are coupled to a first power source and a second power source (not shown) respectively, and the first power source and the second power source respectively provide two different voltages. The plurality of brackets 3 are electrically connected to the first input bus 1 and the second input bus 2, and each bracket 3 includes an output port 34, the output ports 34 being configured to provide an output voltage to a load (not shown). The output port 34 may include one or more output terminals (e.g., two output terminals as shown in fig. 1), the number of output terminals being unlimited. The plurality of circuit breaker modules 4 are respectively assembled to the plurality of brackets 3, and each circuit breaker module 4 comprises a circuit breaker 5 and an adapter 6, wherein the adapter 6 is detachably assembled to the circuit breaker 5. By turning on or off the circuit breaker 5, the electrical connection between the load and each power supply can be correspondingly turned on or off. In any of the circuit breaker modules 4 and their corresponding assembled carriers 3, when the adapter 6 is removed from the circuit breaker 5 (as shown in fig. 2A, i.e., when the adapter 6 is not assembled to the circuit breaker 5), the circuit breaker 5 is electrically connected to the first input bus 1, and when the adapter 6 is assembled to the circuit breaker 5 (as shown in fig. 2B), the circuit breaker 5 is electrically connected to the second input bus 2 through the adapter 6.

Thus, through the detachable adapter 6, the circuit breaker 5 can be electrically connected to different power sources having different voltages, so that the output port 34 can provide different output voltages. Therefore, the power distribution plate can respectively provide proper voltage to each load connected with the power distribution plate according to actual requirements, so that the application flexibility of the power distribution plate is greatly improved.

The adapter 6 is connected between the breaker 5 and the bracket 3. The added adapter 6 of the present invention only increases the distance between the circuit breaker 5 and the bracket 3, compared to the prior art where the circuit breaker is directly attached to the bracket. In other words, the projection direction of the adapter 6 assembled to the bracket 3 is covered by the projection direction of the corresponding breaker 5 assembled to the bracket 3, so that the distance between the input bus and the output port 34 of the bracket 3 is not affected, i.e. the height of the bracket 3 is not increased, and the height of the power distribution board can be maintained unchanged. From the side view of the power distribution plate of fig. 2B, the adaptor 6 added in the present invention only extends the length of the power distribution plate in the horizontal direction (generally, the overall depth), and does not affect the dimension of the power distribution plate in the vertical direction (generally, the overall height). In practical applications, the power distribution tray is installed in the cabinet, and the height of the cabinet is generally critical to the space planning compared to the depth of the cabinet, so the present invention can provide better space planning flexibility.

Fig. 3A and 3B are schematic perspective views of the circuit breaker module 4 of fig. 1 from different angles. Fig. 4 is a schematic cross-sectional view of the circuit breaker module 4 of fig. 1. Fig. 5A and 5B are schematic exploded views of the adapter 6 of fig. 1 from different angles. Please refer to fig. 1 to 5B. The following is a detailed structure illustrating the power distribution tray.

The bracket 3 includes a first input hollow portion 31, a second input hollow portion 32, and an output hollow portion 33. The circuit breaker 5 includes an input 51 and an output 52. The adapter 6 includes a housing 60, an input adapter 61, and an output adapter 62. The housing 60 is formed by assembling the first component 601 and the second component 602, and the housing 60 defines an inner space. The input adapter 61 and the output adapter 62 are at least partially accommodated in the inner space. The first component 601 and the second component 602 may be secured, for example, but not limited to, by a snap fit or a lock fit. The input adapter 61 has a first portion 611, a second portion 612, and a third portion 613 electrically connected to each other, wherein the diameter of the second portion 612 is greater than or equal to the diameter of the third portion 613. The output adapter 62 has a first end 621 and a second end 622 electrically connected to each other. The input 51, output 52, input adapter 61 and output adapter 62 may be formed of any electrically conductive material (e.g., copper). In some embodiments, the adapter 6 further comprises a label 64 attached to the housing 60, wherein the label 64 is used to label the information related to the adapter 6.

As shown in fig. 1 and 2A, when the adapter 6 is removed from the circuit breaker 5, the input end 51 of the circuit breaker 5 is at least partially inserted into the first input hollow portion 31 and electrically connected to the first input bus 1, and the output end 52 is at least partially inserted into the output hollow portion 33 and electrically connected to the output port 34. In this case, the output voltage provided by the output port 34 is derived from the first power supply.

As shown in fig. 1, 2B and 4, when the adapter 6 is assembled to the circuit breaker 5, the input adapter 61 is electrically connected to the input terminal 51, and the input adapter 61 is at least partially inserted into the second input hollow portion 32 and is electrically connected to the second input bus 2. Specifically, at least a portion of the input adapter 61 is inserted into the second input hollow 32 through the first input hollow 31. The first portion 611 is electrically connected to the input end 51, wherein the first portion 611 preferably has a first recess 614 for the input end 51 to be engaged with the first recess 614, but not limited thereto. The second portion 612 is inserted and located in the first input hollow portion 31, and the second portion 612 is covered by the insulating member 616, so as to insulate the input adapter 61 from the first input bus 1. In some embodiments, the insulating member 616 comprises two portions, and the two portions of the insulating member 616 are integrally formed with the first component 601 and the second component 602, respectively (as shown in fig. 5A). The third portion 613 is inserted into the second input hollow 32 through the first input hollow 31, and the third portion 613 is electrically connected to the second input bus 2. In addition, when the adapter 6 is assembled to the circuit breaker 5, the output adapter 62 is electrically connected to the output end 52, and the output adapter 62 is at least partially inserted into the output hollow portion 33 and is electrically connected to the output port 34. Specifically, the first end 621 is electrically connected to the output end 52, and the second end 622 is inserted into the output hollow 33 and is electrically connected to the output port 34. The first end 621 preferably has a second recess 623, so that the output end 52 is engaged in the second recess 623, but not limited thereto. In this case, the input terminal 51 is electrically connected to the second input bus 2 through the input adaptor 61, the output terminal 52 is electrically connected to the output port 34 through the output adaptor 62, and the output voltage provided by the output port 34 is derived from the second power source.

Please refer to fig. 5A and fig. 5B. In some embodiments, the third portion 613 of the input adapter 61 comprises a first resilient member 615. When the third portion 613 is inserted into the second input hollow portion 32, the first elastic member 615 is compressed and abuts against the inner wall of the second input hollow portion 32, thereby fixing the third portion 613 in the second input hollow portion 32. Furthermore, the first elastic member 615 has conductivity, and the inner wall of the second input hollow portion 32 has conductivity and is electrically connected to the second input bus 2. Therefore, the third portion 613 can be electrically connected to the second input bus 2 through the contact between the first elastic member 615 and the inner wall of the second input hollow portion 32. In addition, two first elastic members 615 are shown in this embodiment, but in practice, since the amount of current transmitted by the conductive element is determined by the diameter thereof, the number of first elastic members 615 depends on the diameter of the first elastic members 615. The smaller the diameter of the first resilient element 615, the more first resilient element 615 the third portion 613 needs to contain to transmit sufficient current.

In some embodiments, the second end 622 of the output adapter 62 includes a second elastic member 624. When the second end 622 is inserted into the output hollow portion 33, the second elastic member 624 is compressed and abuts against the inner wall of the output hollow portion 33, thereby fixing the second end 622 in the output hollow portion 33. Furthermore, the second elastic member 624 has conductivity, and the inner wall of the output hollow portion 33 has conductivity and is electrically connected to the output port 34. Thus, the second end 622 may be electrically connected to the output port 34 through contact between the second elastic member 624 and the inner wall of the output hollow 33.

In some embodiments, the power distribution tray also includes a communication bus (not shown). The circuit breaker 5 includes a warning end 53, wherein the warning end 53 is used for outputting a warning signal. The adapter 6 includes a warning adapter 63, and the warning adapter 63 is at least partially accommodated in the inner space of the housing 60. The cradle 3 includes a warning port 35 coupled to the communication bus. When the adapter 6 is removed from the circuit breaker 5 (i.e. when the adapter 6 is not assembled to the circuit breaker 5), the alarm terminal 53 is coupled to the alarm port 35. When the adapter 6 is assembled to the circuit breaker 5, the alarm adapter 63 is coupled between the alarm terminal 53 and the alarm port 35. Therefore, whether the adapter 6 is assembled with the circuit breaker 5 or not, the warning signal can be transmitted to the communication bus to warn when the overcurrent condition is detected.

In summary, the present invention provides a power distribution board having two input buses respectively coupled to two power sources having different voltages. The circuit breaker is electrically connected to one of the input buses through the adapter connected with the circuit breaker. And when the circuit breaker is not assembled to the adapter (i.e., the adapter is removed from the circuit breaker), the circuit breaker is electrically connected to the other input bus. Therefore, the circuit breaker can be selectively coupled to one of the two input buses according to the actual application requirements by connecting or not connecting the adapter, and the power distribution plate can provide two different output voltages according to the requirements, so that the application flexibility can be improved.

It should be noted that the above-mentioned preferred embodiments are only presented for illustrating the invention, and that the invention is not limited to the described embodiments, the scope of which is defined by the appended claims. And the invention may be modified in various ways by those skilled in the art without departing from the scope of the invention as set forth in the appended claims.
