[0047] Figure 1 This is an assembly diagram of a power plug and a socket box provided in an embodiment of this disclosure. Figure 1 As shown, the power supply plug is designed for detachable installation on the plug-in side of the plug box 100 and can be plugged into the busbar trunking for power supply. The power supply plug includes a plug 20.

[0048] like Figure 1 As shown, the plug 20 includes an insulating member 21 and a power-feeding prong 22 disposed on the insulating member 21. The upper section of the plug 20 is the insertion part 201, and the lower section is the wiring part 202.

[0049] The wiring part 202 is used to be inserted into the plug box 100, and the plug part 201 is used to be exposed on the plug side and inserted into the busbar groove.

[0050] The portion of the insulating component 21 corresponding to the wiring portion 202 is fixed to the plug box 100. The portion of the power-taking plug 22 corresponding to the wiring portion 202 is used for electrical connection with the wiring inside the plug box 100. The portion of the power-taking plug 22 corresponding to the plug portion 201 is used for electrical connection with the conductive plate inside the busbar trunking.

[0051] The power plug can be detachably installed onto the plug-in side of the socket box 100, facilitating modular design. When the power plug is installed into the socket box 100, the wiring portion 202 of the plug 20 is inserted into the socket box 100 to connect the wiring, while the plug portion 201 is located outside the socket box 100 and is used to insert into the busbar trough. The plug 20 includes an insulating member 21 and power-feeding prongs 22 disposed on the insulating member 21. The portion of the insulating member 21 corresponding to the wiring portion 202 is used to fix the plug 20 in the socket box 100, serving to secure it. The portion of the power-feeding prongs 22 corresponding to the wiring portion 202 is used to connect the wiring. The portion of the power-feeding prongs 22 corresponding to the plug portion 201 is used to electrically connect with the conductive plate in the busbar trough. This power plug has a simple structure, and the plug 20 can be assembled into the socket box 100 as a module, facilitating individual production and easy assembly.

[0052] Figure 2 This is a schematic diagram of a power outlet provided in an embodiment of this disclosure. Figure 2 As shown, the power plug includes a housing 10 and multiple plugs 20.

[0053] The housing 10 has a plurality of plug openings 10a on the first side and a wiring opening 10b on the second side.

[0054] The structure of the plug 20 is similar to Figure 1 The plug 20 shown has the same structure as the power outlet plug. Figure 3 This is provided by the embodiments of this disclosure. Figure 2 The diagram shows the assembly structure of the power plug and the junction box. Figure 3 As shown, the housing 10 is detachably mounted to the plug side of the plug box 100, such that the plug opening 10a is exposed outside the plug box 100, and the wiring opening 10b is located inside the plug box 100.

[0055] Multiple plugs 20 are respectively disposed in multiple plug openings 10a, and the insertion portion 201 of each plug 20 is exposed on the first side of the housing 10; the wiring portion 202 of each plug 20 is inserted into and fixed inside the housing 10, opposite to the wiring opening 10b.

[0056] By providing a plug opening 10a and a wiring opening 10b on the housing 10, the plug 20 can be disposed in the plug opening 10a. The insertion portion 201 of the plug 20 extends from the plug opening 10a relative to the housing 10 and is used to insert into the busbar groove. The wiring portion 202 of the plug 20 is fixed inside the housing 10 and is opposite to the wiring opening 10b, thus facilitating wiring. This power plug has a simple structure, and the plug 20 can be assembled into the housing 10 as a module, facilitating individual production and easy assembly.

[0057] Figure 4This is a schematic diagram of the structure of a housing provided in an embodiment of this disclosure. For example... Figure 4 As shown, the 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 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.

[0058] 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.

[0059] The number of plug openings 10a can be set according to the number of plugs 20. As an example, the power plug of this embodiment includes 3 plugs 20 and the upper housing 11 has 3 plug openings 10a.

[0060] 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.

[0061] The housing 10 can be in the shape of a right prism, and the plug 20 extends from one end of the right prism. Setting the housing 10 in the shape of a right prism facilitates the storage and assembly of the power plug and makes it easy to modularize.

[0062] like Figure 4 As shown, the outer wall of the housing 10 has a snap fastener 101. The snap fastener 101 is used to connect the connector to the connector box.

[0063] The latches 101 can be distributed on multiple side walls of the lower housing 12. The number of latches 101 distributed on different side walls of the lower housing 12 can be the same or different. When connecting the power plug to the socket box, the lower housing 12 can be directly placed into the corresponding assembly position on the socket box, and the latches 101 will engage with the socket box. The latches 101 are easy to connect and facilitate the modularization of the power plug.

[0064] like Figure 4 As shown, the housing 10 has a foolproof structure 11a. The foolproof structure 11a and the plug opening 10a are located on the same surface of the housing 10. By providing the foolproof structure 11a, the power plug is prevented from being installed backwards when connected to the busbar.

[0065] In this embodiment of the present disclosure, there are two anti-foolproof structures 11a, which are respectively disposed on opposite sides of the plug opening 10a. Figure 5 This is a schematic diagram of a power outlet provided in an embodiment of this disclosure. Figure 5 As shown, the distances from the two foolproof structures 11a to the plug opening 10a are different.

[0066] As an example, the foolproof structure 11a can be a groove or a protrusion. This embodiment uses a groove as an example. In this embodiment, the plug opening 10a is located on the upper housing 11, and the foolproof structure 11a is also located on the upper housing 11. When the power plug is inserted into the busbar slot, the foolproof structure 11a prevents the power plug from being inserted incorrectly. The busbar slot has protrusions that mate with the foolproof structure 11a. When the power plug is successfully inserted into the busbar slot, the protrusions on the busbar slot fit precisely into the two foolproof structures 11a. The protrusions on the busbar slot can be raised ridges that fit with the foolproof structure 11a with a clearance.

[0067] Since the plug opening 10a is located between the two foolproof structures 11a, and the distances from the two foolproof structures 11a to the plug opening 10a are different, when the power plug is accidentally connected in reverse, multiple plugs 20 can be inserted into the busbar groove. However, the foolproof structure 11a cannot be aligned with the protrusion on the busbar groove, causing the protrusion to be unable to engage with the foolproof structure 11a. This prevents the power plug from being properly inserted, thus avoiding the danger caused by incorrect circuit wiring.

[0068] In some examples, the two foolproof structures 11a are of different sizes.

[0069] Taking the anti-mistake structure 11a as an example, the dimensions of the anti-mistake structure 11a may include at least one of the depth and width of the groove. The two anti-mistake structures 11a may have different depths and / or widths.

[0070] In some examples, the widths of the two foolproof structures 11a can be different. The widths of the protrusions that mate with the two foolproof structures 11a are also different. This way, if the power plug is accidentally plugged into the busbar when it is inserted into the busbar, the power plug cannot be inserted properly because the widths of the foolproof structures 11a and the protrusions do not match, thus preventing the circuit from being connected incorrectly and causing danger.

[0071] In some examples, the depths of the two foolproof structures 11a can be different. The heights of the protrusions that mate with the two foolproof structures 11a are also different. This way, if the power plug is accidentally plugged into the busbar when it is inserted into the busbar, the power plug cannot be inserted properly because the depths of the foolproof structures 11a and the protrusions do not match, thus preventing the circuit from being connected incorrectly and causing danger.

[0072] In other examples, the depth and width of the two foolproof structures 11 can also be different, which can also prevent the danger caused by incorrect circuit connection.

[0073] Figure 6 This is an exploded structural diagram of a plug provided in an embodiment of this disclosure. Figure 7 This is a schematic diagram of the assembly structure of a plug provided in an embodiment of this disclosure. Figure 6 and Figure 7 As shown, the plug 20 includes an insulating component 21 and a power-generating prong 22. The insulating component 21 includes a plug-in section 211 and a wiring fixing section 212. The plug-in section 211 is located outside the housing 10, and the wiring fixing section 212 is located inside the housing 10 and is connected to the 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 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 connector 22 includes a power-taking section 221 and a wiring section 222. The power-taking section 221 is located outside the housing 10, on one side of the plug-in section 211, and opposite to the plug-in section 211. The wiring section 222 is located inside the housing 10, on one side of the wiring fixing section 212, and opposite to the wiring fixing section 212. The wiring section 222 is connected to the wiring fixing section 212.

[0076] The plug 20's insertion section 201 includes a power-taking section 221 and a insertion section 211, and the wiring section 202 includes a wiring section 222 and a wiring fixing section 212.

[0077] The wiring segment 222 of the power-taking plug 22 is connected to the insulating member 21, and the plug segment 211 is used to contact the conductive plate in the busbar when the power-taking plug is connected to the busbar. The wiring segment 222 is inside the housing 10 to connect to the wire introduced through the wiring opening 10b.

[0078] Optionally, the plug 20 may include one or two power-feeding prongs 22. When the plug 20 includes two power-feeding prongs 22, the two power-feeding plugs 20 are located on opposite sides of the insulator 21.

[0079] In the plurality of plugs 20 of the power outlet, at least one plug 20 includes two power-feeding prongs 22, which are located on opposite sides of the insulator 21 and are insulated from each other. For example, Figure 2 or Figure 5 The power supply plug includes three plugs 20, two of which each include two power-feeding prongs 22, and the third plug 20 includes one power-feeding prong 22. The plug 20 including one power-feeding prong 22 can be used to contact the conductive plate connected to the ground wire in the busbar trunking.

[0080] By providing power-taking prongs 22 on opposite sides of the insulating member 21, and ensuring that the two prongs 22 are insulated, a plug 20 can connect to two conductive plates of different phases in the busbar trunking, allowing the plug 20 to conduct two currents of different phases. For example, see... Figure 5The power plug shown has a total of 5 power supply prongs 22 from left to right. From left to right, they can be grounding prong, N-phase prong, L1-phase prong, L-phase prong, and L2-phase prong.

[0081] like Figure 6 As shown, the power-taking section 221 has a power-receiving portion 2211 that protrudes away from the insulating member 21, and the power-receiving portion 2211 has a power-receiving surface 2211a.

[0082] When the power plug is inserted into the busbar trough, the contact part 2211 can make the contact surface 2211a in close contact with the conductive plate under the action of deformation, so as to achieve good conductivity.

[0083] Even if the power tap 22 deteriorates in deformation due to prolonged use, the plug 20 is still supported by the insulating part 21. With the support of the insulating part 21, the power tap 22 can still maintain good conductivity with the conductive plate.

[0084] like Figure 6 As shown, the power-taking section 221 includes multiple conductive springs 2212, which are arranged independently and at intervals. The multiple conductive springs 2212 are comb-shaped, and each conductive spring 2212 has a grounding part 2211. The grounding surfaces 2211a of the multiple conductive springs 2212 are coplanar.

[0085] Figure 8 This is a schematic diagram of the structure of a conductive spring provided in an embodiment of this disclosure. For example... Figure 8 As shown, the conductive contact 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. (Refer to...) Figure 5 As shown, the first inclined plate a1 is close to the bottom of the power plug, and the second inclined plate a3 is far away from the bottom of the power plug. The bottom of the power plug is also close to the upper housing 11.

[0086] The first oblique plate a1, the flat plate a2, and the second oblique plate a3 form the aforementioned contact portion 2211, and the surface of the flat plate a2 away from the insulating member 21 forms a contact surface 2211a.

[0087] In this way, when the power plug is inserted into the busbar groove, the contact part 2211 of each conductive spring 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 contact surface 2211a fits tightly with the conductive plate, thereby achieving good conductivity.

[0088] 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 is relatively large, the total area of ​​the contact surface 2211a can be increased by increasing the number of conductive springs 2212 to allow the large current to pass through.

[0089] The power take-off plug 22 includes multiple conductive springs 2212. These conductive springs 2212 are independent of each other. Therefore, 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 and the conductive plate of the busbar remain in a conductive state.

[0090] 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.

[0091] For example, the power-taking plug 22 can be a stamped structural component, and multiple conductive springs 2212 can be directly formed by stamping.

[0092] like Figure 5 As shown, the portion of the insulating element 21 located outside the housing 10 is arrow-shaped. Figure 9 This is a schematic diagram of the structure of an insulating component provided in an embodiment of this disclosure. For example... Figure 9 As shown, the plug section 211 includes a connected vertical plate 2111 and a guide section 2112.

[0093] Figure 10 yes Figure 5 A magnified view of a portion of the image. (See attached image.) Figure 10 As shown, the end of the power-taking plug 22 near the guide portion 2112 is housed in the space between the bottom of the guide portion 2112 and the vertical plate 2111, and the power-connecting surface 2211a is located outside the space between the bottom of the guide portion 2112 and the vertical plate 2111.

[0094] 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 10 As shown, the end of the second inclined plate a3 away from the flat plate a2 is received in the space between the bottom of the guide portion 2112 and the vertical plate 2111, while the surface of the flat plate a2 away from the vertical plate 2111 is outside the space between the bottom of the guide portion 2112 and the vertical plate 2111. The surface of the flat plate a2 away from the vertical plate 2111 is the contact surface 2211a.

[0095] 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 guide 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 connector box. If the contact portion 2211 tilts outward, it may affect the insertion of the plug 20 into the busbar groove.

[0096] The contact surface 2211a is located outside the space between the bottom of the guide section 2112 and the vertical plate 2111 in order to avoid the guide section 2112 interfering with the contact surface 2211a and the conductive plate in the busbar groove.

[0097] It can be seen that the guide portion 2112 of the insulating component 21 plays a role in protecting the power-taking plug 22 and preventing the power-taking plug 22 from tilting outward.

[0098] In addition, the guide portion 2112 of the insulating member 21 also plays a guiding role during the process of inserting the plug 20 into the insertion slot 111, making it easier to insert.

[0099] like Figure 6 and Figure 7 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.

[0100] The pressure plate 231 is located inside the housing 10 and is located on the side 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.

[0101] 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 member 21 clamp the wiring segment 222 of the power taking plug 22, ensuring that the power taking plug 22 is installed firmly.

[0102] Safety plate 232 is located outside housing 10 and is connected to pressure plate 231. Safety plate 232 is located on the side of power tap 22 away from plug section 211. The height of safety plate 232 is less than the height of power tap 22, and the width is greater than or equal to the width of power tap 22.

[0103] Since the safety plate 232 is located on the side of the power-taking plug 22 away from the insulator 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 7 As shown, the height of the safety plate 232 is less than the height of the power tap 22. (Referring to...) Figure 2As shown, the height of the safety plate 232 is the length of the safety plate 232 extending relative to the housing 10, and the height of the power tap 22 is the length of the power tap 22 extending relative to the housing 10.

[0104] To further enhance safety, the width of the safety plate 232 is greater than or equal to the width of the power-taking tab 22. (Refer to...) Figure 7 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.

[0105] The safety plate 232 provides protection because when a technician holds the plug box and inserts the plug 20 into the busbar, their fingers may touch the bottom of the power take-off piece 22 of the plug 20, that is, the position of the power take-off piece 22 near the housing 10. However, because the bottom of the power take-off piece 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.

[0106] like Figure 6 and Figure 7 As shown, the plug 20 also includes a terminal block 24, which is located in the 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.

[0107] For example, the terminal block 24, the wiring segment 222, and the wiring fixing segment 212 can be connected by bolts.

[0108] The terminal 24 contacts the wiring segment 222 of the power supply plug 22. When wiring, the cable extends into the housing 10 from the wiring opening 10b and connects to the terminal 24.

[0109] like Figure 6 As shown, the terminal block 24 includes a sheet-like body 241 and a wiring tube 242. At least one end of the wiring tube 242 is open, and the open end of the wiring tube 242 is opposite to the wiring opening 10b.

[0110] 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.

[0111] 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.

[0112] For example, the connector 242 is a stamped structural part, which is formed by bending after stamping.

[0113] like Figure 6 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.

[0114] For a plug 20 that includes two power-feeding prongs 22, the two power-feeding prongs 22 can be connected to the insulating member 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.

[0115] 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.
