Plug boxes and busbar systems

Abstract

This disclosure provides a plug box and busbar system, belonging to the field of plugs. The plug box includes a housing and a power supply plug, the power supply plug being partially located within and connected to the housing. The power supply plug includes multiple plugs, each plug extending at least partially relative to a side wall of the housing. The multiple plugs include at least one first plug, whose two insulated sides are used to contact a conductive plate in a plug slot of the busbar trunking. These two sides of the first plug correspond to different polarities. Since both opposite sides of the first plug are used to contact the conductive plate in the plug slot of the busbar trunking, and these opposite sides correspond to different polarities, one first plug is equivalent to two plugs in related technologies, thereby reducing the number of plugs and making the plug box structure simpler and smaller.

Description

[0001] This disclosure claims priority to Chinese Patent Application No. 202210266566.3, filed on March 17, 2022, entitled "Busbar Plug-in Structure, Busbar Trunking, Plug-in Connector and Locking Structure", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of plugs, and more particularly to a plug box and a busbar system. Background Technology

[0003] Busbar trunking is a high-current transmission device consisting of metal plates such as copper or aluminum as conductive plates, supported by insulating materials, and encased in a metal shell. Compared to traditional cables, busbar trunking offers significant advantages in power transmission, including easier installation and maintenance, and a longer service life, leading to its increasingly widespread application.

[0004] A plug-in box is a device that connects electrical equipment to a busbar trunking. When making a connection, the plug of the plug-in box is inserted into the busbar trunking and makes contact with the conductive plate in the busbar trunking to draw power. Different plugs are connected to conductive plates of different polarities. For example, in a three-phase power supply, each of the three plugs is connected to one phase. Summary of the Invention

[0021] On the other hand, embodiments of this disclosure also provide a bus system, the bus system comprising:

[0022] The busbar trunking has multiple plug slots, including at least one first plug slot, in which two conductive plates are arranged opposite to each other.

[0038] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram of the structure of a plug-in box provided in an embodiment of this disclosure. For example... Figure 1 As shown, the plug box includes a box body 30 and a power plug 40. The power plug 40 is partially located in the box body 30 and is connected to the box body 30.

[0041] Figure 2 This is a schematic diagram of a power plug provided in an embodiment of this disclosure. Figure 2As shown, the power plug 40 includes a plurality of plugs 20 spaced apart from each other, with at least a portion of each plug 20 extending out from the side wall of the housing 30. The plurality of plugs 20 includes at least one first plug 2001, with two spaced-apart sides of the first plug 2001 for contacting a conductive plate in a plug slot of the busbar trunking, the two sides of the first plug 2001 corresponding to different polarities.

[0042] By setting up a housing 30 and a power supply plug 40, the power supply plug 40 is connected to the housing 30. The power supply plug 40 includes multiple plugs 20, which extend relative to the side wall of the housing 30. When connecting to the busbar trunking, the plugs 20 can be inserted into the plug slots of the busbar trunking. The multiple plugs 20 include at least one first plug 2001. Since both insulated sides of the first plug 2001 are used to contact the conductive plate in the plug slot of the busbar trunking, and these two sides of the first plug 2001 correspond to different polarities, that is, one first plug 2001 is equivalent to two plugs in the related technology, thereby reducing the number of plugs and making the plug box structure simpler and smaller. For example, in a four-wire or five-wire wiring method, the related technology requires four or five plugs, while in this embodiment, only two or three plugs are needed.

[0043] like Figure 1 As shown, the housing 30 has a module mounting port 30a on one side, and the power plug 40 is installed in the module mounting port 30a.

[0044] like Figure 2 As shown, the power plug 40 also includes a module housing 10, which has a wiring opening 10b and multiple plug openings 10a. The wiring opening 10b is located in the housing 30, and the plug openings 10a are located on the side of the module housing 10 away from the housing 30. Multiple plugs 20 are respectively inserted into the multiple plug openings 10a.

[0045] In this embodiment, the power supply plug 40 adopts a modular design, with the plug 20 inserted into the plug opening 10a of the module housing 10. This design is simple, facilitating assembly and storage. The power supply plug 40 is inserted into the module mounting port 30a, and the modular design of the connector box facilitates assembly.

[0046] Figure 3 This is a schematic diagram of the structure of a module housing provided in an embodiment of this disclosure. Figure 3 As shown, the module housing 10 includes a detachably connected upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 can be connected by screws, snap-fit, or adhesive. In some examples, the module housing 10 can also be a one-piece structure, that is, the upper housing 11 and the lower housing 12 are a single connected structure.

[0047] The plug opening 10a is located on the upper housing 11, and the wiring opening 10b is located on the lower housing 12, specifically on the side wall of the lower housing 12.

[0048] The number of plug openings 10a can be set according to the number of plugs 20. As an example, the power plug 40 of this embodiment includes 3 plugs 20 and the upper housing 11 has 3 plug openings 10a.

[0049] The number of plugs 20 in the connector is related to the number of plug slots in the busbar trunking. For example, if the busbar trunking includes three plug slots, then the connector includes three plugs 20, and each plug 20 is inserted into a plug slot 111.

[0050] The module housing 10 can be in the shape of a right prism, such as a cuboid or a cube. The plug 20 extends from one end of the right prism. Setting the module housing 10 in the shape of a right prism facilitates the storage and assembly of the power plug 40 and promotes modularity.

[0051] like Figure 3 As shown, the outer side wall of the module housing 10 has a buckle 101, which is engaged with the box body 30.

[0052] The clips 101 can be distributed on multiple side walls of the lower housing 12. The number of clips 101 distributed on different side walls of the lower housing 12 can be the same or different. When connecting the power plug 40 to the socket box, the lower housing 12 can be directly placed into the corresponding assembly position on the socket box, and the clips 101 will engage with the socket box. The clips 101 are easy to connect and facilitate the modularization of the socket box.

[0053] Figure 4 This is a schematic diagram illustrating the assembly of a power plug and a housing according to an embodiment of this disclosure. Figure 4 As shown, at least one side wall of the module housing 10 has a foolproof protrusion 102, and the housing 30 has a foolproof notch 30b. The foolproof notch 30b is located at the edge of the module mounting port 30a, and the foolproof protrusion 102 is located in the foolproof notch 30b.

[0054] When installing the power connector 40 into the module mounting port 30a, the anti-foolproof protrusion 102 must be aligned with the anti-foolproof notch 30b to ensure the power connector 40 can be installed smoothly. The cooperation between the anti-foolproof protrusion 102 and the anti-foolproof notch 30b prevents the power connector 40 from being installed backwards. The cooperation between the anti-foolproof protrusion 102 and the anti-foolproof notch 30b also serves as a guide, preventing the power connector 40 from tilting during installation.

[0055] Exemplarily, in this embodiment of the present disclosure, one sidewall of the module housing 10 has a foolproof protrusion 102, and a corresponding foolproof notch 30b is provided on the housing 30. In other examples, one or more foolproof protrusions 102 may be provided on multiple sidewalls of the module housing 10, such as two opposite sidewalls or two adjacent sidewalls. One or more foolproof notches 30b are then provided on the housing 30. For example, when foolproof protrusions 102 are provided on two opposite sidewalls of the module housing 10, the foolproof protrusions 102 on the two sidewalls are asymmetrical, where symmetry refers to central symmetry. The foolproof protrusions 102 on the two sidewalls are asymmetrical, that is, when the foolproof protrusion 102 of the power plug 40 is aligned with the foolproof notch 30b, after rotating the power plug 40 180°, the foolproof protrusion 102 on the sidewall and the foolproof notch 30b on the housing 30 are not aligned with each other. For example, when anti-mistake protrusions 102 are provided on two adjacent side walls of the module housing 10, the anti-mistake protrusions 102 on the two side walls are asymmetrical. Here, symmetry refers to rotational symmetry. The anti-mistake protrusions on the two side walls are asymmetrical, that is, when the anti-mistake protrusion 102 of the power plug 40 is aligned with the anti-mistake notch 30b, if the power plug 40 is rotated by a certain angle, such as 90°, the anti-mistake protrusion 102 on the side wall and the anti-mistake notch 30b on the housing 30 will not be aligned with each other.

[0056] Figure 5 This is a schematic diagram illustrating the assembly of another power supply plug and housing according to an embodiment of this disclosure. Figure 5 As shown, in another possible implementation, in this example, at least one sidewall of the module housing 10 has a first anti-mistake groove 103, and the housing 30 has an anti-mistake protrusion 102 located at the edge of the module mounting port 30a and in the first anti-mistake groove 103.

[0057] This example is compared to Figure 4 The example shown is equivalent to swapping the positions of the anti-foolproof protrusion 102, and placing the anti-foolproof protrusion 102 on the housing 30. When installing the power plug 40 into the module mounting port 30a, align the end of the first anti-foolproof groove 103 with the anti-foolproof protrusion 102, so that the anti-foolproof protrusion 102 slides into the first anti-foolproof groove 103.

[0058] Figure 6 This is a schematic diagram of a power plug provided in an embodiment of this disclosure. Figure 6 As shown, the module housing 10 also has two second anti-mistake grooves 11a. The second anti-mistake grooves 11a and the plug opening 10a are located on the same surface of the module housing 10, and the two second anti-mistake grooves 11a are located on opposite sides of the plug opening 10a. The two second anti-mistake grooves 11a are at different distances from the insertion portion of their respective nearest plugs 20, where the insertion portion of the plug 20 refers to the part of the plug 20 that extends out of the module housing 10.

[0059] In this embodiment, the plug opening 10a is located on the upper housing 11, and the second anti-misalignment groove 11a is also located on the upper housing 11. When the power plug 40 is inserted into the busbar slot, the second anti-misalignment groove 11a prevents the power plug 40 from being inserted incorrectly. The busbar slot has protrusions that mate with the second anti-misalignment grooves 11a. When the power plug 40 is successfully inserted into the busbar slot, the protrusions on the busbar slot fit precisely into the two second anti-misalignment grooves 11a. The protrusions on the busbar slot can be raised ridges that fit with the second anti-misalignment grooves 11a with a clearance.

[0060] Since the plug opening 10a is located between the two second anti-misalignment slots 11a, and the distances from the two second anti-misalignment slots 11a to the insertion part of the nearest plug 20 are different, when the power plug 40 is accidentally connected in reverse, multiple plugs 20 can be inserted into the busbar groove, but the second anti-misalignment slot 11a cannot be aligned with the protrusion on the busbar groove, causing the protrusion to be unable to engage in the second anti-misalignment slot 11a. This prevents the power plug 40 from being properly inserted, thus avoiding the danger caused by incorrect circuit connection.

[0061] Optionally, the two second mis-proof grooves 11a may have different depths and / or widths.

[0062] In some examples, the widths of the two second anti-misalignment slots 11a can be different. The widths of the protrusions that mate with the two second anti-misalignment slots 11a are also different. This way, if the power plug 40 is accidentally plugged into the busbar groove and is connected backwards, the power plug 40 cannot be properly inserted because the widths of the second anti-misalignment slots 11a and the protrusions do not match, thus preventing the circuit from being connected incorrectly and causing danger.

[0063] In some examples, the depths of the two second anti-misalignment slots 11a may be different. The heights of the protrusions that mate with the two second anti-misalignment slots 11a are also different. This way, if the power plug 40 is accidentally plugged into the busbar slot when it is plugged in, the power plug 40 cannot be plugged in properly because the depths of the second anti-misalignment slots 11a and the protrusions do not match, thus preventing the circuit from being connected incorrectly and causing danger.

[0064] In other examples, the depth and width of the two second misaligned slots 11a can also be different, which can also prevent the danger caused by incorrect circuit connection.

[0065] Figure 7 This is an exploded structural diagram of a plug provided in an embodiment of this disclosure. Figure 8 This is a schematic diagram of the assembly structure of a plug provided in an embodiment of this disclosure. Figure 7 and Figure 8 As shown, the plug 20 includes an insulating plate 21 and a power-feeding prong 22.

[0066] Of the plurality of plugs 20 in the power plug 40, at least one plug 20 includes two power-feeding prongs 22, which are located on opposite sides of the insulating plate 21 and are insulated from each other. For example, Figure 2 In the middle, the power plug 40 includes three plugs 20, including two first plugs 2001 and one second plug 2002.

[0067] In this embodiment of the present disclosure, the first plug 2001 includes an insulating plate 21 and two power-collecting prongs 22. The two power-collecting prongs 22 are located on opposite sides of the insulating plate 21 and are insulated from each other. The two power-collecting prongs 22 correspond to different polarities.

[0068] The two power-taking terminals 22 correspond to different polarities, meaning that when DC power is input, the two power-taking terminals 22 are connected to the positive and negative terminals respectively, and when AC power is input, the two power-taking terminals 22 are connected to different phase lines respectively, or to the phase line and the neutral line respectively.

[0069] When the power plug 40 draws power, the two power-drawing prongs 22 make contact with the two conductive plates in one of the plug slots of the busbar trunking. In the same plug slot, when the busbar trunking supplies DC power, the two conductive plates are connected to the positive and negative terminals respectively; when the busbar trunking supplies AC power, the two conductive plates are connected to different phase wires or a phase wire and a neutral wire respectively.

[0070] Since the two power-taking prongs 22 are arranged on opposite sides of the insulating plate 21 and are insulated from each other, when the power-taking plug 40 is connected to the busbar, the connection between the two poles can be achieved through a first plug 2001, thereby reducing the number of plugs and making the power-taking plug 40 smaller.

[0071] The second plug 2002 includes an insulating plate 21 and a power-taking plug 22, with the power-taking plug 22 located on one side of the insulating plate 21.

[0072] The second plug 2002 can be used for grounding. When the power plug 40 is connected to the busbar trunking, the second plug 2002 contacts the grounded conductive plate in the busbar trunking through a power plug 22, thereby grounding the plug box.

[0073] like Figure 7 As shown, the insulating plate 21 includes a plug-in section 211 and a wiring fixing section 212. The plug-in section 211 is located outside the module housing 10, and the wiring fixing section 212 is located inside the module housing 10 and is connected to the module housing 10.

[0074] Optionally, connecting portions 2121 may be connected to both sides of the wiring fixing section 212, and the connecting portions 2121 are used to connect to the module housing 10. For example, the connecting portion 2121 has a connecting hole, and the connecting portion 2121 is connected to the upper housing 11 by screws.

[0075] The power-taking plug 22 includes a power-taking section 221 and a wiring section 222. The power-taking section 221 is located outside the module housing 10 and on one side of the plug section 211. The wiring section 222 is located inside the module housing 10 and on one side of the wiring fixing section 212, and the wiring section 222 is connected to the wiring fixing section 212.

[0076] The wiring segment 222 of the power-taking plug 22 is connected to the insulating plate 21, and the plug segment 211 is used to contact the conductive plate in the busbar when the power-taking plug 40 is connected to the busbar. The wiring segment 222 is inside the module housing 10 to connect with the wire introduced through the wiring opening 10b.

[0077] like Figure 7 As shown, the power-taking section 221 has a power-receiving portion 2211 that protrudes away from the insulating plate 21, and the power-receiving portion 2211 has a second power-receiving surface 2211a.

[0078] When the power plug 40 is inserted into the busbar trough, the power receiving part 2211 can make the second power receiving surface 2211a in close contact with the conductive plate under the action of deformation, so as to achieve good conduction.

[0079] Even if the power tap 22 deteriorates in deformation due to prolonged use, the plug 20 is still supported by the insulating plate 21. With the support of the insulating plate 21, the power tap 22 can still maintain good conductivity with the conductive plate.

[0080] like Figure 7 As shown, the power-taking section 221 includes multiple conductive springs 2212. The multiple conductive springs 2212 are independent of each other and are arranged at intervals to each other in a comb-like shape. Each conductive spring 2212 has a power-receiving part 2211.

[0081] Figure 9 This is a schematic diagram of the structure of a conductive spring provided in an embodiment of this disclosure. For example... Figure 9 As shown, the conductive spring 2212's contact portion 2211 may include a first inclined plate a1, a flat plate a2, and a second inclined plate a3 connected in sequence. The first inclined plate a1 is close to the bottom of the power plug 40, and the second inclined plate a3 is away from the bottom of the power plug 40. The bottom of the power plug 40 is also close to the upper housing 11.

[0082] The first oblique plate a1, the flat plate a2, and the second oblique plate a3 form the aforementioned electrical contact portion 2211, and the surface of the flat plate a2 away from the insulating plate 21 forms the second electrical contact surface 2211a.

[0083] In this way, when the power plug 40 is inserted into the busbar groove, the contact portion 2211 of each conductive spring piece 2212 is squeezed, causing the first inclined piece a1 and the second inclined surface a2 to deform in a flattening direction, which causes the outer end face of the flat piece a2 to fit tightly with the conductive plate in the busbar groove. That is, the second contact surface 2211a fits tightly with the conductive plate, thereby achieving good conductivity.

[0084] The power tap 22 includes multiple conductive springs 2212. The number of conductive springs 2212 can be controlled to adapt to the magnitude of the transmitted current. For example, if the current transmitted by the power tap 40 is relatively large, the total area of ​​the second contact surface 2211a can be increased by increasing the number of conductive springs 2212 to allow a large current to pass through.

[0085] The power take-off plug 22 includes multiple conductive springs 2212. These conductive springs 2212 are independent of each other. So even if one or more conductive springs 2212 have poor contact with the conductive plate of the busbar due to deformation, it will not affect the other conductive springs 2212, so that the power take-off plug 40 and the conductive plate of the busbar remain in a conductive state.

[0086] When the power-collecting plug 22 is a one-piece molded sheet structure, that is, multiple conductive springs 2212 are connected into a whole, the power-receiving part 2211 of the power-collecting plug 22 may also include the first inclined plate a1, the flat plate a2 and the second inclined plate a3 mentioned above.

[0087] For example, the power-taking plug 22 can be a stamped structural component, and multiple conductive springs 2212 can be directly formed by stamping.

[0088] like Figure 6 As shown, the portion of the insulating plate 21 located outside the module housing 10 is arrow-shaped. Figure 10 This is a schematic diagram of the structure of an insulating plate provided in an embodiment of this disclosure. Figure 10 As shown, the plug-in section 211 includes a connected vertical plate 2111 and an arrowhead section 2112.

[0089] Figure 11 yes Figure 6 A magnified view of a portion of the image. (See attached image.) Figure 11 As shown, the end of the power-taking plug 22 near the arrow portion 2112 is housed in the space between the bottom of the arrow portion 2112 and the vertical plate 2111, and the second power-taking surface 2211a is located outside the space between the bottom of the arrow portion 2112 and the vertical plate 2111.

[0090] The power-taking section 221 of the power-taking plug 22 has a power-receiving part 2211, and the power-receiving part 2211 includes a first inclined plate a1, a flat plate a2, and a second inclined plate a3 connected in sequence. Therefore, as... Figure 11As shown, the end of the second oblique piece a3 away from the flat piece a2 is received in the space between the bottom of the arrow part 2112 and the vertical plate 2111, while the surface of the flat piece a2 away from the vertical plate 2111 is outside the space between the bottom of the arrow part 2112 and the vertical plate 2111. The surface of the flat piece a2 away from the vertical plate 2111 is the second electrical contact surface 2211a.

[0091] In one example, the end of the second inclined plate a3 furthest from the flat plate a2 is housed in the space between the bottom of the arrowhead portion 2112 and the vertical plate 2111. This is to protect the second inclined plate a3 from tilting away from the vertical plate 2111 during the transport and handling of the power connector 40. If the power connection portion 2211 tilts outward, it may affect the insertion of the connector 20 into the busbar groove.

[0092] The second contact surface 2211a is located outside the space between the bottom of the arrow part 2112 and the vertical plate 2111 in order to avoid the arrow part 2112 interfering with the contact between the second contact surface 2211a and the conductive plate in the busbar groove.

[0093] It can be seen that the arrow part 2112 of the insulating plate 21 serves to protect the power receiving plug 22 and prevent the power receiving plug 22 from tilting outward.

[0094] In addition, the arrow portion 2112 of the insulating plate 21 also plays a guiding role during the process of inserting the plug 20 into the insertion slot 111, making it easier to insert.

[0095] like Figure 7 and Figure 8 As shown, the plug 20 also includes a clamping member 23, which includes a pressure plate 231 and a safety plate 232. The clamping member 23 is an insulating member, that is, it is made of insulating material.

[0096] The pressure plate 231 is located inside the module housing 10 and is located on the side of the wiring section 222 of the power take-up plug 22 away from the wiring fixing section 212. The pressure plate 231, the wiring section 222 and the wiring fixing section 212 are connected.

[0097] For example, the pressure plate 231, the wiring segment 222 and the wiring fixing segment 212 are connected by bolts. The pressure plate 231 and the wiring fixing segment 212 of the insulating plate 21 clamp the wiring segment 222 of the power taking plug 22, ensuring that the power taking plug 22 is installed firmly.

[0098] Safety plate 232 is located outside module housing 10 and is connected to pressure plate 231. Safety plate 232 is located on the side of power take-up plug 22 away from plug section 211. The height of safety plate 232 is less than the height of power take-up plug 22, and the width is greater than or equal to the width of power take-up plug 22.

[0099] Since the safety plate 232 is located on the side of the power-taking plug 22 away from the insulating plate 21, if the safety plate 232 is too high, it may interfere with the contact between the power-taking plug 22 and the conductive plate of the busbar. Therefore, if... Figure 8 As shown, the height of the safety plate 232 is less than the height of the power tap 22. The height of the safety plate 232 is the length of the safety plate 232 extending out of the module housing 10, and the height of the power tap 22 is the length of the power tap 22 extending out of the module housing 10.

[0100] To further enhance safety, the width of the safety plate 232 is greater than or equal to the width of the power-feeding insert 22. (Refer to...) Figure 8 As shown, the width of the safety plate 232 is the length along the arrangement direction of the multiple conductive spring contacts 2212, and the width of the power-taking plug 22 is also the length along the arrangement direction of the multiple conductive spring contacts 2212. The width of the safety plate 232 is greater than or equal to the width of the power-taking plug 22, so that the safety plate 232 blocks all the conductive spring contacts 2212.

[0101] The safety plate 232 provides protection because when a technician holds the power plug 40 and inserts the plug 20 of the power plug 40 into the busbar, their fingers may touch the bottom of the power tap 22 of the plug 20, that is, the position of the power tap 22 near the module housing 10. However, because the bottom of the power tap 22 is shielded by the safety plate 232, the technician's fingers will only touch the safety plate 232. Since the safety plate 232 is insulated, the technician will not be electrocuted.

[0102] like Figure 7 and Figure 8 As shown, the plug 20 also includes a terminal block 24, which is located in the module housing 10 and on the side of the wiring segment 222 away from the wiring fixing segment 212. The terminal block 24, the wiring segment 222 and the wiring fixing segment 212 are connected, and the terminal block 24 is opposite to the wiring opening 10b.

[0103] For example, the terminal block 24, the wiring segment 222, and the wiring fixing segment 212 can be connected by bolts.

[0104] The terminal 24 contacts the wiring segment 222 of the power take-up plug 22. When wiring, the cable extends from the housing 30 through the wiring opening 10b into the module housing 10 and connects to the terminal 24.

[0105] like Figure 7 As shown, the terminal block 24 includes a sheet-like body 241 and a connector 242. At least one end of the connector 242 is open, and the open end of the connector 242 is opposite to the wiring opening 10b.

[0106] One side of the sheet-like body 241 is connected to the outer wall of the wiring tube 242, and the sheet-like body 241 is attached to the wiring segment 222 of the power-taking plug 22, and the power-taking plug 22 is clamped by the action of the bolt.

[0107] During wiring, the cable is inserted into the conduit 242 and connected to the terminal 24. For example, the conduit 242 can be clamped with pliers to deform it and clamp the cable.

[0108] For example, the connector 242 is a stamped structural part, which is formed by bending after stamping.

[0109] like Figure 7 As shown, the plug 20 also includes a first washer 251 and a second washer 252. The first washer 251 is located on the side of the sheet-like body 241 away from the wiring segment 222 of the power-taking plug 22, and the second washer 252 is located on the side of the wiring segment 222 of the power-taking plug 22 away from the sheet-like body 241. The first washer 251 and the second washer 252 can increase the area of ​​the wiring segment 222 that is compressed after the bolt is tightened, thus preventing the wiring segment 222 from being damaged due to an insufficiently small area of ​​compression.

[0110] For a plug 20 that includes two power-feeding prongs 22, the two power-feeding prongs 22 can be connected to the insulating plate 21 in the same way. That is, the clamping member 23 is set one-to-one with the power-feeding prongs 22, and the wiring terminal 24 is also set one-to-one with the power-feeding prongs 22.

[0111] This disclosure also provides a busbar system. The busbar system includes busbar trunking and, for example... Figures 1 to 11 The diagram illustrates any type of plug-in box. The busbar trunking has multiple plug slots, including at least one first plug slot containing two conductive plates arranged opposite each other. Multiple plugs 20 of the plug-in box are used to plug into the multiple plug slots. Specifically, a first plug 2001 is used to plug into the first plug slot, and the two insulated sides of the first plug 2001 are used to contact the two conductive plates in the first plug slot respectively. This allows two phases of electricity to be connected through a single first plug 2001, which helps reduce the number of plugs 20.

[0112] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
