Description

Technical Field

[0001] This utility model relates to an electrical control box, and more particularly to an electrical control box suitable for use in confined maintenance spaces, belonging to the field of electrical control box manufacturing technology. Background Technology

[0002] An electrical control box is a combination of one or more low-voltage switchgear devices and related control, measurement, signaling, protection, and regulation equipment. The main functions of an electrical control box are: 1. Power distribution: The main function of the electrical control box is to distribute electrical energy from the power source to different circuits, ensuring that each circuit receives a reasonable power supply. This is achieved through internal switching devices and conversion devices, such as transformers that convert high voltage to low voltage to meet the power needs of different equipment; 2. Circuit protection: The electrical control box is equipped with various protection devices, such as fuses, circuit breakers, and overcurrent relays, to provide overload protection, short-circuit protection, etc. When a fault occurs in the circuit, these protection devices will automatically cut off the power supply to prevent the fault from spreading or causing equipment damage, thereby ensuring personal safety and the normal operation of electrical equipment; 3. Circuit control: The electrical control box can achieve manual and automatic control of the circuit through control switches. This allows operators to flexibly adjust the operating status of the circuit as needed.

[0003] like Figure 1 As shown, when an electrical control box is assembled into a system, all other system components and the electrical control box 1 are installed in a cabinet 2. After the system cabinet is assembled, an access port (not shown in the figure) is provided on the cabinet 2 above the electrical control box 1 for future maintenance. When maintaining the electrical control box 1, the cables connecting the other components inside the cabinet 2 to the electrical control box 1 need to be disconnected through the access port, and then the entire electrical control box 1 can be removed from the access port for maintenance. However, this operation is very difficult in actual maintenance work because the installation space of the electrical control box 1 in the cabinet 2 is already very limited. In addition, many other components (not shown in the figure) need to be installed in the cabinet 2, and electrical conduits connecting the various components (not shown in the figure) also need to be installed in the cabinet 2. This makes the operating space for maintaining the electrical control box 1 very limited. During maintenance, it is very difficult to disconnect the cables connected to the electrical control box from the upper maintenance port within the very limited maintenance space inside the cabinet, and then remove the electrical control box as a whole. This greatly increases the intensity of maintenance work, prolongs maintenance time, and reduces maintenance efficiency.

[0004] In summary, how to redesign an electrical control box that is suitable for maintenance operations in confined spaces, reduces the workload of maintenance workers, shortens maintenance time, and improves maintenance efficiency is an urgent technical problem to be solved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an electrical control box suitable for use in confined maintenance spaces, which is suitable for maintenance operations in confined spaces, reduces the workload of maintenance workers, shortens maintenance time and improves maintenance efficiency, in order to address the deficiencies in the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an electrical control box suitable for use in confined maintenance spaces, comprising a box body and a box cover. The box body is fixed to the inner side of the system cabinet, and the top of the box body is set as an opening. The box cover is detachably connected to the opening at the top of the box body, thereby keeping the interior of the box body closed. Inside the box body, a box body partition is detachably connected. Various electrical component modules of the electrical control box are arranged on the side of the box body partition. A cable socket is also provided on one side of the box body partition. After the cable plug with cable passes through one side of the box body and enters the interior of the box body, the cable plug can be plugged into the cable socket to achieve electrical connection.

[0007] Preferably, the lid is rectangular, with straight edges on three sides and a beveled edge on the remaining side. Two protruding strips are positioned on opposite sides of the top of the box body. One side of the first protruding strip is a recessed edge at the bottom, and the other side of the second protruding strip is a beveled edge. When the lid is connected to the top of the box body, the bottom of the lid contacts the top of the box body, and one straight edge of the lid engages with the recessed edge of the first protruding strip. The beveled edge of the lid contacts the beveled edge of the second protruding strip. Screws are used to lock the lid onto the box body, thus sealing the interior of the box.

[0008] Preferably, a sealing groove is provided on the top of the box, and a sealing ring is placed in the sealing groove; when the screws lock the box cover to the box, the box cover is used to press the sealing ring onto the top of the box.

[0009] Preferably, the lid is rectangular, with one side having a stepped edge and the other three sides having straight edges. Two protruding strips are positioned on opposite sides of the top of the box body. One side of protruding strip one has a recessed edge at the bottom and a slanted edge above the recessed edge. One side of protruding strip two has a straight edge. A sealing ring is positioned on the bottom of the lid and runs around its perimeter. When the lid is connected to the top of the box body, the bottom of the lid contacts the top of the box body, and the stepped edge of one side of the lid inserts into the recessed edge of protruding strip one. The straight edge of the lid on the opposite side contacts the straight edge of protruding strip two. A tightening screw passes through protruding strip two and contacts the straight edge of the lid on the opposite side, thus tightening the lid. After tightening, the lid is locked to the box body with screws, thus sealing the interior of the box body.

[0010] Preferably, the box partition is connected to the inside of the box via a plug-in structure, thereby allowing the box partition to be detachably connected to the inside of the box.

[0011] Preferably, a vertically distributed slot 1 and slot 2 are respectively provided on the inner side of the opposite sides of the box body, a connecting piece 1 is also provided on the inner side of the box body located at the top of slot 1, a connecting piece 2 is also provided on the inner side of the box body located at the top of slot 2, and a connecting piece 3 and a connecting piece 4 are respectively provided on the top of the opposite sides of the box body partition.

[0012] By inserting the opposite sides of the box partition into slot one and slot two respectively, and then using screw one to lock connecting piece one and connecting piece three, and using screw two to lock connecting piece two and connecting piece four, the box partition is connected to the inside of the box through a plug-in structure.

[0013] Preferably, a cable sealing joint is also provided on one side of the enclosure, and the cable passes through the cable sealing joint and connects with the cable sealing joint before extending into the interior of the enclosure.

[0014] Preferably, a wire tie handle is also provided on one outer side of the box.

[0015] Preferably, the lid is also provided with a handle.

[0016] The beneficial effects of this utility model are as follows: This utility model divides the electrical control box into three parts: the box body, the box body partition, and the box cover. During the overall assembly of the system cabinet, the box body is installed first, and the cable plug is inserted into the box body in a ready-to-connect state. In effect, the box body and cable plug are designed as fixed parts, while the box body partition and box cover are designed as movable parts. Therefore, during maintenance, it is not necessary to remove the entire electrical control box as in the prior art; only the box body partition needs to be removed for maintenance. In addition, since the connection position of the cable plug and cable socket is located inside the box body, the insertion and removal operations between the cable plug and cable socket can be performed inside the box body, unlike the prior art which requires the insertion and removal operations between the cable plug and cable socket outside the box body. This avoids the electrical conduits of other components of the system occupying space and affecting the insertion and removal operations. Thus, the maintenance operations of this utility model can all be performed through the maintenance port, which is suitable for maintenance operations in confined maintenance spaces, reducing the workload of maintenance workers, shortening maintenance time, and improving maintenance efficiency. When connecting the lid and the body, this invention allows for screwing only on three sides of the rectangular lid, depending on the actual installation conditions. For the remaining side of the rectangular lid where screws cannot be tightened due to lack of operating space, the design incorporates a groove in the body's protrusion to secure the lid's straight edge, replacing the original screw locking function. This ensures the lid is locked onto the top of the body, guaranteeing the airtightness of the internal space. Attached Figure Description

[0034] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1: As Figures 2 to 4 As shown, an electrical control box suitable for use in confined maintenance spaces includes a box body 3 and a cover 4. The top of the box body 3 is an opening, and the cover 4 is detachably connected to the opening at the top of the box body 3, thus keeping the interior of the box body 3 closed. Inside the box body 3, a partition 5 is connected via a plug-in structure. The partition 5 vertically divides the interior of the box body 3 into two internal spaces. Various electrical component modules are mounted on the sides of the partition 5. Here, various electrical component modules such as a PLC module 7, a disconnector module 8, a power supply module 9, and a contactor module 10 can be installed on one side of the partition 5, so that all electrical component modules are located in one internal space. However, as in this embodiment, various electrical component modules can also be installed on opposite sides of the partition 5, so that various electrical component modules are located in two separate internal spaces. A cable socket 11 is also provided on one side of the partition 5. Figure 5 As shown, one end of the cable 12 is connected to a cable plug 121, and the other end of the cable 12 is connected to other components of the system. The cable plug 121, with the cable 12 attached, passes through one side of the housing 3 near the cable socket 11 and enters the interior of the housing 3. The cable plug 121 is then plugged into the cable socket 11 to establish an electrical connection between the control box and other components of the system, ensuring the normal operation of the control box. At this time, the cable plug 121 and the cable socket 11 that it mates with are both located within the same internal space of the housing.

[0036] In this embodiment, the electrical control box is divided into three parts: the box body, the box body partition, and the box cover. During the final assembly of system cabinet 2, as follows... Figure 6 As shown, first, assemble the enclosure 3 onto one inner side of the cabinet 2 and connect the cable 12 to the other components of the system. Then, pass the cable 12 through the enclosure 3 so that the cable plug 121 is inside the enclosure 3. At this point, the cabinet 2 is fully assembled, leaving only the maintenance port located above the electrical control box (not shown in the figure). Next, install various electrical component modules and cable sockets onto the enclosure partition 5 on the outside of the cabinet, completing the assembly of the enclosure partition 5. Then proceed as follows... Figure 7 As shown, the enclosure partition 5 is vertically inserted into the interior of the enclosure 3 through the access port located above the electrical control box. Then, the cable plug 121 is plugged into the cable socket 11 to establish electrical connection between the electrical control box and other components of the system. Finally, the enclosure cover 4 is connected to the opening at the top of the enclosure 3 through the access port, completing the installation of the electrical control box. For maintenance, simply open and remove the enclosure cover 4 through the access port, unplug the cable plug 121 from the cable socket 11, and then remove the enclosure partition 5 (containing various electrical components and the cable socket) from the access port. Maintenance can then be performed outside the enclosure. After maintenance, the enclosure partition 5 is reinserted through the access port, the cable plug 121 is plugged into the cable socket 11, and finally the enclosure cover 4 is closed.

[0037] Therefore, this embodiment, through the above design, divides the electrical control box into three parts: the box body, the box body partition, and the box cover. During the overall assembly of the system cabinet, the box body is installed first, and the cable plug is inserted into the box body in a ready-to-connect state. In effect, the box body and cable plug are designed as fixed parts, while the box body partition and box cover are designed as movable parts. Therefore, during maintenance, it is not necessary to remove the entire electrical control box as in the prior art; only the box body partition needs to be removed for maintenance. In addition, since the connection position of the cable plug and cable socket is located inside the box body, the insertion and removal operations between the cable plug and cable socket can be performed inside the box body, unlike the prior art which requires the insertion and removal operations between the cable plug and cable socket outside the box body. This avoids the electrical conduits of other components of the system occupying space and affecting the insertion and removal operations. Thus, maintenance operations in this embodiment can all be performed through the maintenance port, which is suitable for maintenance operations in confined maintenance spaces, reducing the workload of maintenance workers, shortening maintenance time, and improving maintenance efficiency.

[0038] like Figure 2 and Figure 5As shown, a cable sealing connector 13 is provided on one side of the enclosure 3. The cable 12 passes through the cable sealing connector 13 and connects with it before extending into the interior of the enclosure 3. This cable sealing connector 13 further ensures the airtightness of the enclosure interior. A cable tie handle 14 is also provided on one outer side of the enclosure 3. Cables outside the enclosure 3 can be tied tightly to the cable tie handle 14, ensuring cable neatness and making it suitable for confined installation spaces. A protruding enclosure mounting plate 15 is also provided on the opposite side of the enclosure 3. Screws passing through the mounting plate 15 facilitate the installation of the enclosure 3 onto the inner side of the system cabinet 2. A grounding connector 16 is also provided on the side of the enclosure 3.

[0039] In addition, to ensure the airtightness of the box interior, the lid 4 needs to be tightly closed onto the opening at the top of the box body 3. In existing technology, screws are used in all four directions around the lid 4 to lock it onto the opening at the top of the box body 3. However, if... Figure 7 As shown, in actual installation conditions, a protruding cabinet edge 211 is provided at the top of one side of the system cabinet 2, as shown. Figure 8 As shown, the protruding edge 211 of the cabinet is located at the top of one side of the installed box 3. Due to the obstruction of the protruding edge 211, it is impossible to use screws to lock the cover 4 to the box opening at the top of the box 3 on this side of the box 3, thus failing to guarantee the internal sealing of the box. Therefore, the applicant redesigned the locking and sealing structure between the cover 4 and the box opening at the top of the box 3, such as... Figure 2 and Figure 8 As shown, in this embodiment, the lid 4 is rectangular, with three sides forming straight edges 411, and the remaining side forming a beveled edge 412. Figures 8 to 10 As shown, a first cabinet protrusion 311 and a second cabinet protrusion 312 are respectively provided on opposite sides of the top of the cabinet 3. The cabinet protrusion 211 is located above the first cabinet protrusion 311 on one side of the installed cabinet 3. One side of the first cabinet protrusion 311 is configured as a lower groove edge 313 and an upper cabinet inclined edge 314. One side of the second cabinet protrusion 312 is configured as a second cabinet inclined edge 315. A complete sealing groove is also provided on the top of the cabinet 3, and a sealing ring 17 is placed in the sealing groove. Figure 11 and Figure 12 As shown, when installing the lid 4, first place the lid 4 on top of the box body 3, so that the inclined edge 412 of the lid 4 contacts the inclined edge 315 of the box body protrusion 312, and the straight edge 411 of the lid 4 on the side opposite to the inclined edge 412 contacts the inclined edge 314 of the box body protrusion 311, and then... Figure 2As shown, when a downward force F is applied to the box body 3, the box cover 4 moves downward, and finally, as shown... Figure 12 As shown, the bottom of the lid 4 contacts the top of the body 3, and the straight edge 411 of the lid on one side is engaged in the groove edge 313 of the protrusion 311 of the body. Finally, as shown... Figure 2 As shown, on the other three sides of the lid 4, which are not obstructed by the cabinet protrusion 211, screws 18 are used to lock the lid 4 onto the cabinet 3, completing the sealing of the interior of the cabinet 3. In this embodiment, based on actual installation conditions, screws are only tightened on three sides of the rectangular lid. On the remaining side of the rectangular lid where screws cannot be tightened due to lack of operating space, the groove of the cabinet protrusion 1 is used to clamp the straight edge of the lid, replacing the original screw tightening function. This ensures that the lid can be locked onto the top of the cabinet, guaranteeing the airtightness of the interior space. Furthermore, when the lid 4 contacts the top of the cabinet 3, the lid 4 also presses against the sealing ring 17 located on the top of the cabinet 3, further ensuring the airtightness of the interior space.

[0040] like Figure 2 As shown, a handle 19 is also provided on the box cover 4. The box cover can be picked up and put down by the handle 19, which can further improve the maintenance efficiency.

[0041] like Figure 13 and Figure 14 As shown, vertically distributed slots 19 and 2 (not shown in the figure) are respectively provided on the inner sides of opposite sides of the box body 3. A connecting piece 20 is also provided on the inner side of the box body located at the top of slot 19, and a connecting piece 2 (not shown in the figure) is also provided on the inner side of the box body located at the top of slot 2. A connecting piece 3 21 and a connecting piece 4 22 are respectively provided on the top of opposite sides of the box body partition 5. During installation, the opposite sides of the box body partition 5 are inserted into slots 19 and 2, respectively. Then, screw 1 is used to lock connecting piece 20 and connecting piece 3 21, and screw 2 is used to lock connecting piece 2 and connecting piece 4 22, thereby inserting the box body partition 5 into the inside of the box body 3.

[0042] like Figure 14 As shown, an inner fold 23 is also provided at the top of the enclosure partition 5, and part of the cable socket 11 is installed on the inner fold 23, which facilitates the connection between the cable plug and the cable socket.

[0043] Example 2: The difference from Example 1 is as follows: Figure 15 and Figure 16As shown, the lid 4 is rectangular, with one side perimeter set as a stepped lid edge 413, and the other three sides perimeter set as straight lid edges 411; one side of the first box body protrusion 311 is set as a lower groove edge 313 and a box body inclined edge 314 above the groove edge, one side of the second box body protrusion 312 is set as a straight box body edge 316, and the sealing ring 17 is set on the bottom of the lid 4 and is set in a whole circle along the perimeter of the lid 4. After installing the lid 4, the bottom of the lid 4 contacts the top of the box body 3, and the stepped edge 413 of the lid 4 on one side is inserted into the groove edge 313 of the first ridge 311 of the box body. The straight edge 411 of the lid 4 on the opposite side contacts the straight edge 316 of the second ridge 311 of the box body. Then, the tightening screw 24 is used to horizontally pass through the second ridge 312 of the box body and contact the straight edge 411 of the lid 4 on the opposite side, thereby tightening the lid 4. After tightening, as in Embodiment 1, the lid 4 is locked onto the box body 3 on the other three sides of the lid 4 that are not obstructed by the ridge edge 211 of the box body, using screws 18 to complete the sealing of the inside of the box body 3. In this way, when the lid is installed, the addition of the tightening screw creates a tightening force on the lid, allowing the lid to press the sealing ring tighter, further improving the sealing effect around the lid, and thus further ensuring the sealing performance of the internal space of the box body.

[0044] In summary, this utility model divides the electrical control box into three parts: the box body, the box body partition, and the box cover. During the overall assembly of the system cabinet, the box body is installed first, and the cable plug is inserted into the box body in a ready-to-connect state. This effectively makes the box body and cable plug fixed parts, while the box body partition and box cover are movable parts. Therefore, during maintenance, it is not necessary to remove the entire electrical control box as in existing technologies; only the box body partition needs to be removed for maintenance. Furthermore, since the connection point between the cable plug and the cable socket is located inside the box body, the plugging and unplugging operations can be performed inside the box body, unlike existing technologies which require external plugging and unplugging. This avoids the electrical conduits of other system components occupying space and affecting the plugging and unplugging operations. Thus, all maintenance operations of this utility model can be performed through the maintenance port, making it suitable for maintenance operations in confined spaces, reducing the workload of maintenance workers, shortening maintenance time, and improving maintenance efficiency. When connecting the lid and the body, this invention allows for screwing only on three sides of the rectangular lid, depending on the actual installation conditions. For the remaining side of the rectangular lid where screws cannot be tightened due to lack of operating space, the design incorporates a groove in the body's protrusion to secure the lid's straight edge, replacing the original screw locking function. This ensures the lid is locked onto the top of the body, guaranteeing the airtightness of the internal space.

Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
