Description

Technical Field

[0001] The present invention relates to the field of electricity, and more particularly to an electrical cabinet. Background Art

[0002] An electrical cabinet generally includes a cabinet body and a plurality of electrical modules accommodated in the cabinet body. The cabinet body is built by columns and crossbeams, etc. The electrical modules often need to communicate with the outside and also need to be electrically connected to the outside. In the prior art, communication bus cables or electrical connection buses are mostly attached to the front end of the column. Since hanging ears are generally provided on both sides of the electrical module and the hanging ears are attached to the front surface of the column, the bus must be located in front of the hanging ears. When the electrical module needs to be maintained, when the electrical module is pulled out forward, it will be blocked by the bus, making it difficult to pull out the electrical module. In the prior art, there is also a wire tying rack installed at the front end of the column. The communication bus cable or the electrical connection bus is placed in the wire tying rack, and then the branch cables connected to each electrical module pass through the side of the wire tying rack and are connected to the electrical module. However, since the branch cables connected to the electrical modules are welded to the bus, the welding points will make the branch cables have a certain flexibility. After the branch cables pass through the side of the wire tying rack, they will be inclined and bent, and the inclined part will still block the pulling out of the electrical module, making it difficult to pull and push the electrical module. If the electrical module is not to be blocked by the branch cables, the column must be designed very wide, and this design will increase the floor area of the entire electrical cabinet. In actual applications, generally multiple electrical cabinets are used in combination, and this structure has a greater impact on the space; if the force is too large, it may also cause the cables connected to the electrical modules to peel off from the bus. Summary of the Invention

[0012] Based on Technical Solution 7, there is also provided Technical Solution 8. In Technical Solution 8, the column is further provided with a first limiting wall and a second limiting wall that are perpendicular to the second direction and located in the same plane.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In Technical Solution 1, the main cable can be placed in the wire groove inside the column. The branch cables connected to each electrical module can pass through the wire passing holes on the front surface of the column and then be connected to the wiring ports of each electrical module. The electrical module is provided with a protruding part protruding from the front surface of the column, and the branch cables can be supported by the supporting surface of the protruding part, thus avoiding the contact between the branch cables and adjacent electrical modules, which may affect the pulling out of the electrical module. Moreover, there is a supporting surface between the welding point of the branch cable and the main cable and the connection point between the branch cable and the wiring port, so that the two connection points are less stressed and the connection is more stable. The covering member is connected to the front end of the electrical module and covers the wiring port, so that only the cables between the wire passing holes and the side of the electrical module are exposed, and the cables in the rest parts are either hidden inside the column or hidden behind the covering member, which is more beautiful. After the branch cable passes through the front surface of the column, the front end of the electrical module protrudes from the column, so that the cables exposed between the front surface of the column and the side of the electrical module are basically in the blind area of sight, and the impact on aesthetics can be basically ignored. When the electrical module needs to be maintained, open or remove the covering member, remove the branch cable from the wiring port, and then remove the electrical module, and the electrical module can be pulled out forward. Since the wire passing holes are opened on the front surface of the column, the welding of the branch cable and the main cable makes the branch cable tilt forward without affecting the electrical module. After the electrical module is maintained, install the electrical module in the cabinet and lock it to the column through the hanging ear. When the hanging ear abuts against the front surface of the column, the electrical module is installed in place. Since the protruding part protrudes from the front surface of the column, the branch cable coming out of the wire passing hole can be directly connected to the wiring port on the protruding part, and the operation is convenient. It can be seen that by adopting this technical solution, the electrical module basically does not contact the branch cable when being pulled out, thus ensuring the stable connection between the branch cable and the main cable, and making the electrical module smooth when being pulled out during maintenance. The structure of this technical solution also makes the wiring or disconnection of the electrical module and the branch cable convenient, and the cables are basically hidden as a whole, which is more beautiful. In addition, in this solution, there is no need to separately set up a wire tying rack, and the cables are directly accommodated in the space inside the column, which is more ingenious. In practical applications, there are also problems related to the welding of the branch cable and the main cable and the passing of the branch cable through the wire passing holes. In this solution, the main cable can be placed into the wire groove through the notch of the wire groove, and then the branch cable and the main cable are welded. After welding, the branch cables are passed through the respective wire passing holes one by one. Therefore, this solution has enough space for the operator to weld and thread the wires, and the operation is convenient.

[0017] 2. In Technical Solution 2, the protruding part is provided with at least two accommodating cavities. An accommodating groove with an opening facing forward is formed between two adjacent accommodating cavities. The supporting surface is arranged corresponding to the outside of the accommodating cavity, so that the branched cable coming out of the wire splitting hole can be connected to the wiring port in the accommodating groove or the wiring port in the accommodating cavity. In practical applications, the wiring port in the accommodating cavity can extend out from the wire passing port to facilitate connection with the branched cable. With the above structure, when connecting the branched cable to the wiring port in the accommodating groove, it can be first supported by the supporting surface, and when connecting the branched cable to the wiring port in the accommodating cavity, it can also be first supported by the supporting surface, making the wiring convenient. Moreover, the branched cable is more regular and orderly inside the protruding part. And compared with the overall forward protrusion of the electrical module, the accommodating space in this solution is larger, and when the covering part is connected to the electrical module, it is basically not hindered by the cable, which is more convenient.

[0018] 3. In Technical Solution 3, the covering part can cooperate with the supporting surface to form a wire passing channel extending along the second direction. The wire passing channel is communicated with the accommodating groove. The covering part can cooperate with the accommodating groove to form an accommodating space. When the branched cable is long, the redundant part can be accommodated in the wire passing channel or the accommodating space, and the covering part can hinder the movement of the branched cable. The wire passing port is arranged close to the accommodating groove, so that when connecting the branched cable to the wiring port of the accommodating cavity, the redundant part of the cable can also enter the accommodating groove, that is, the accommodating space can make the redundant part of the branched cable be accommodated therein. In this way, when the covering part is connected, since it does not contact the cable, the hindrance is small and the connection is more convenient.

[0019] 4. In Technical Solution 4, the two accommodating cavities are close to both ends of the protruding part, and the hanging ears are correspondingly arranged on the outer side of the outermost accommodating cavity. Since the wire passing port is arranged close to the accommodating groove, the cable passing through the wire passing hole will be first supported by the supporting surface and then connected to the wiring port. The connection point between the welding point of the branched cable and the bus and the connection point between the branched cable and the wiring port is supported by the supporting surface, so that the two connection points are basically not stressed and the connection is more stable.

[0020] 5. In Technical Solution 5, the second wall can be used as the handle of the entire electrical module to facilitate the forward extraction of the electrical module.

[0021] 6. In Technical Solution 6, the setting of the protective sleeve can prevent the branched cable from being worn and damaged when passing through the wire passing hole.

[0022] 7. In Technical Solution 7, the notch of the wire routing groove faces the side of each electrical module, which is more beautiful and convenient for the juxtaposition of multiple electrical cabinets.

[0023] 8. In Technical Solution 8, the first limiting wall and the second limiting wall are provided for the side of the electrical module to abut against, so as to limit the electrical module along the second direction.

[0024] 9. In Technical Solution Nine, since the cable generally falls naturally under gravity to the lower end of the wire passing hole, the first direction is the vertical direction, and the supporting surface is flush with the lower end of the wire passing hole, so that the edge of the wire passing hole can form a certain support for the cable, and the bending of the branched cable passing through the wire passing hole is basically in the same plane, making the wire routing more regular and beautiful. Moreover, it ensures that the welding point between the branched cable and the main cable is not easily detached, and the branched cable is not easily damaged due to excessive contact and friction with the edge of the protruding part.

[0025] 10. In Technical Solution Ten, a first positioning portion is provided on the first abutting surface of the electrical module, and a second positioning portion is provided on the abutting wall of the covering member. When installing the covering member, the second positioning portion can be first inserted into the first positioning portion along the third direction, and then the first covering wall and the connecting wall are locked by fasteners such as screws. Since the connecting wall at least partially extends into the wire passing channel and at least partially corresponds to each accommodating cavity, the locking of the covering member and the electrical module is firm and reliable; the first abutting surface, the supporting surface, the first covering wall and the second covering wall cooperate to form a wire passing channel, and the first covering wall and the accommodating groove cooperate to form an accommodating space. The structure is simple, beautiful and practical, and avoids the contact between the covering member and the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See Figures 1-7 , Figures 1-7 which shows an electrical cabinet, including a cabinet body 10, an electrical module 20, a covering member 30 and a protective sleeve 40.

[0042] See Figure 2 and Figure 4 , the cabinet body 10 is provided with columns 11 extending along a first direction, a wire trough 111 extending along the first direction is arranged inside the column 11, and a plurality of wire passing holes 1111 communicating with the wire trough 111 are arranged on the front surface of the column 11 along the first direction; the opening of the wire trough 111 faces inwards, and the wire passing holes 1111 are opened on the groove wall of the wire trough 111; the column 11 is further provided with a first limiting wall 112 and a second limiting wall 113 that are perpendicular to a second direction and located in the same plane, the second direction is perpendicular to the first direction, and the second direction is the left-right direction in Figure 2 , the first limiting wall 112 is located at the front end of the second limiting wall 113 and extends backward from the free end of the front groove wall of the wire trough 111 to partially cover the notch of the wire trough 111, and the second limiting wall 113 extends backward from the free end of the rear groove wall of the wire trough 111.

[0043] In a specific implementation, the above-mentioned columns 11 can be arranged on both sides of the cabinet body 10, or the above-mentioned columns 11 can be arranged on one side of the cabinet body 10. In practical applications, generally, a plurality of cabinet bodies 10 are used in cooperation. See Figure 1 and Figure 3 , the above-mentioned columns 11 can be arranged on both sides of the middle cabinet body 10, the above-mentioned columns 11 can be arranged on the inner sides of the two outermost cabinet bodies 10, and partition columns 12 are arranged on the outer sides of the two outermost cabinet bodies 10. The partition columns 12 extend along the first direction, and an abutting surface 121 flush with the front surface of the column 11 and a blocking surface 122 perpendicular to the abutting surface 121 and located at the front end of the abutting surface 121 are arranged on the partition columns 12.

[0044] In this embodiment, the first direction is the vertical direction, the second direction is the left-right direction, and the third direction is the front-rear direction.

[0045] The number of the electrical modules 20 is equal to and in one-to-one correspondence with the number of the wire passing holes 1111. Each electrical module 20 is installed in the cabinet body 10 and arranged along the first direction. The notch of the wire trough 111 faces the side of each electrical module 20, which is more beautiful and convenient for the juxtaposition of multiple electrical cabinets. Each electrical module 20 is provided with a protruding part protruding from the front surface of the column 11. The protruding part is provided with at least one wiring port 24 and a supporting surface 22121 perpendicular to the first direction. The supporting surface 22121 corresponds to the wire passing hole 1111. A hanging ear 23 is further provided on the side of the protruding part. The hanging ear 23 is adapted to avoid the wire passing hole 1111 and abut against the front surface of the column 11. When the electrical module 20 is installed, it abuts against the first limiting wall 112 and the second limiting wall 113, so as to be limited along the second direction relative to the cabinet body 10.

[0046] The protruding part is provided with at least two accommodating cavities 01 arranged at intervals along the second direction. The supporting surface 22121 is arranged corresponding to the outside of the accommodating cavity 01. The accommodating cavity 01 is provided with a wire passing opening 011 adapted for the wiring port 24 to extend out. The wire passing opening 011 is also opened on the supporting surface 22121. An accommodating groove 02 with an opening facing forward is formed between two adjacent accommodating cavities 01. The wiring ports 24 are at least three. Each wiring port 24 is respectively arranged in each accommodating cavity 01 and each accommodating groove 02. A connecting wall perpendicular to the third direction is provided on the protruding part. At least part of the connecting wall extends into the wire passing channel 03 and at least part of it corresponds to each accommodating cavity 01.

[0047] See Figure 5 , the electrical module 20 is a battery module. The protruding part is provided with two accommodating cavities 01 and an accommodating groove 02. The two accommodating cavities 01 are close to both ends of the protruding part. The hanging ear 23 is correspondingly arranged on the outer side of the outermost accommodating cavity 01. A fan is placed in the accommodating cavity 01, and a battery management unit is placed in the accommodating groove 02. The wiring ports 24 of the battery management unit and the fan both face upward, and the wiring port 24 of the fan also passes through the wire passing opening 011.

[0048] A first abutting surface 22111 located above and at the rear end of the protruding part is further provided at the front end of the electrical module 20. The first abutting surface 22111 is perpendicular to the third direction. A first positioning part 22112 is provided on the first abutting surface 22111. Figures 5-6 In

[0049] In a specific implementation, the accommodating cavity 01, the accommodating groove 02 and the first abutting surface 22111 are all formed on the shell of the electrical module 20. See Figure 6, the housing of the electrical module 20 includes a base 21 and an upper cover 22. The front end of the base 21 protrudes with a first front bending plate 211 and a connecting plate 212 integrally formed with the first front bending plate 211. The first front bending plate 211 is parallel to the first direction, the connecting plate 212 is parallel to the second direction. The first front bending plate 211 is bent to form two first grooves 2111 arranged at intervals along the second direction. The first grooves 2111 are strip-shaped and extend along the first direction. A second groove 2112 is formed between the two first grooves 2111. The openings of the first grooves 2111 and the second groove 2112 face away from each other. The opening of the second groove 2112 faces forward and forms a receiving groove 02. The connecting plate 212 is also perpendicular to the first direction, and it extends backward from the upper edge of the front bending plate corresponding to the first groove 2111, that is, the connecting plate 212 is located at the upper end of the first groove 2111. In this embodiment, the length of the connecting plate 212 is less than the width of the first groove 2111, so that the connecting plate 212 only partially covers the upper end of the first groove 2111. The front end of the upper cover 22 is provided with a second front bending plate 221. The second front bending plate 221 extends along the second direction and is provided with a first extension wall 2211, a second extension wall 2212 and a third extension wall 2213 that are sequentially connected and integrated. The first extension wall 2211 and the third extension wall 2213 are both perpendicular to the third direction and are oppositely arranged. The second extension wall 2212 is perpendicular to the first direction. The length of the second extension wall 2212 is less than the length of the first extension wall 2211. The length of the third extension wall 2213 is less than the length of the second extension wall 2212. When the upper cover 22 is locked to the base 21, the second extension wall 2212 abuts against the connecting plate 212 and cooperates with the first groove 2111 to form a receiving cavity 01. The upper surface of the second extension wall 2212 forms a supporting surface 22121. The second extension wall 2212 does not block the upper end of the first groove 2111, and the upper end of the first depression forms a wire passing opening 011, that is, the wire passing opening 011 is arranged close to the receiving groove 02. The wire passing opening 011 is opened on the supporting surface 22121. The second extension wall 2212 does not contact the second groove 2112. The first extension wall 2211 is located above and at the rear of the second wall 232 and forms a first abutting surface 22111. The third extension wall 2213 is located above the bottom wall of the first groove 2111 and is in the same plane as it. The third extension wall 2213 and the bottom walls of the two first grooves 2111 corresponding to the first front bending plate 211 form a connecting wall. The length of the third extension wall 2213 along the second direction is much less than the width of the first groove 2111. It can be seen that the wire passing through the wire passing hole 1111 will be first supported by the supporting surface 22121, and then connected to the wiring port 24. The welding point between the branch cable and the main cable to the connection point between the branch cable and the wiring port 24 is supported by the supporting surface 22121, so that the two connection points are basically not stressed and the connection is more stable.

[0050] See Figure 2, the supporting surface 22121 is flush with the lower end of the wire passing hole 1111. Since the cable generally falls naturally under gravity to the lower end of the wire passing hole 1111, the above setting enables the edge of the wire passing hole 1111 to form a certain support for the cable, and makes the bending of the branch cable passing through the wire passing hole 1111 basically in the same plane, making the wire routing more regular and beautiful, and ensuring that the welding point between the branch cable and the main cable is not easily detached, and the branch cable is not easily damaged due to excessive contact and friction with the edge of the protruding part.

[0051] Still referring to Figure 2 , the hanging ear 23 is provided with a first wall 231 for abutting against the front surface of the column 11 and a second wall 232 located at the front end of the first wall 231. The second wall 232 is parallel and opposite to the first wall 231. In a specific implementation, the hanging ear 23 is further provided with a third wall 233 integrally connected to the first wall 231 and the second wall 232. The third wall 233 is perpendicular to the second direction and fixedly connected to the outer side wall of the first front bending plate 211. In this embodiment, the third wall 233 is locked to the groove wall of the first front bending plate 211 corresponding to the first groove 2111. In practical applications, the second wall 232 can be used as a handle for the entire electrical module 20 to facilitate the forward extraction of the electrical module 20.

[0052] The number of covering members 30 is equal to and corresponds one-to-one with the number of electrical modules 20. The covering members 30 are connected to the front end of the electrical modules 20 and are used to cover the wiring ports 24. The covering members 30 are adapted to cooperate with the supporting surface 22121 to form a wire passing channel 03 extending in the second direction. The wire passing channel 03 communicates with the accommodating groove 02; the covering members 30 are further adapted to cooperate with the accommodating groove 02 to form an accommodating space. In this way, the branch cable coming out of the wire splitting hole can be connected to the wiring port 24 in the accommodating groove 02 or the wiring port 24 in the accommodating cavity 01. When the branch cable is relatively long, the redundant part can be accommodated in the wire passing channel 03 or the accommodating space, and the covering members 30 can prevent the movement of the branch cable; the wire passing port 011 is arranged close to the accommodating groove 02, so that when the branch cable is connected to the wiring port 24 of the accommodating cavity 01, the redundant part of the cable can also enter the accommodating groove 02, that is, the accommodating space can accommodate the redundant part of the branch cable. In this way, when the covering members 30 are installed, since they do not contact the cable, the obstruction is small and the connection is more convenient.

[0053] See Figure 7, the covering member 30 includes a first covering wall 31, a second covering wall 32, and an abutting wall 33 that are sequentially connected and integrated. The first covering wall 31 and the abutting wall 33 are both perpendicular to the third direction, parallel to and opposite each other. The second covering wall 32 is perpendicular to the first direction. The abutting wall 33 is provided with a second positioning portion 331 that is inserted into the first positioning portion 22112 along the third direction. In this embodiment, the second positioning portion 331 is a positioning hole adapted to the positioning protrusion. The first covering wall 31 abuts against and is locked to the connecting wall. The first abutting surface 22111, the supporting surface 22121, the first covering wall 31, and the second covering wall 32 cooperate to form a wire passing channel 03. The first covering wall 31 and the accommodating groove 02 cooperate to form an accommodating space. The structure is simple, beautiful and practical, and the contact between the covering member 30 and the cable is avoided.

[0054] When installing the covering member 30, the second positioning portion 331 can be first inserted into the first positioning portion 22112 along the third direction, and then the first covering wall 31 and the connecting wall are locked by fasteners such as screws. Since at least part of the connecting wall extends into the wire passing channel 03 and at least part of it corresponds to each accommodating cavity 01, the locking of the covering member 30 and the electrical module 20 is stable and reliable. However, it should be understood that the covering member 30 can also be rotatably connected to the front end of the electrical module 20.

[0055] See Figure 2 , the number of protective sleeves 40 is equal to the number of wire passing holes 1111, and each protective sleeve 40 is correspondingly placed in each wire passing hole 1111. In a specific implementation, the protective sleeve 40 can be made of a plastic material, and the shape of the protective sleeve 40 can be adapted to the shape of the wire passing hole 1111. The setting of the protective sleeve 40 can prevent the branch cable connected to the electrical module 20 from being worn and damaged when passing through the wire passing hole 1111.

[0056] In a specific application, the main cable can be placed in the wiring groove 111 in the column 11, and the branch cable connected to each electrical module 20 can be passed through the wire hole 1111 on the front surface of the column 11 and connected to the wiring port 24 of each electrical module 20. The electrical module 20 is provided with a protruding portion protruding from the front surface of the column 11, and the branch cable can be supported by the supporting surface 22121 of the protruding portion, thereby avoiding the branch cable from contacting the adjacent electrical module 20 and affecting the pulling of the electrical module 20, and making the support surface support the welding point between the branch cable and the main bus to the connection point between the branch cable and the wiring port , so that the two connection points are basically free of force, and the connection is more stable; the cover 30 locks the front end of the electrical module 20 and covers the wiring port 24, so that only the cables between the wire hole 1111 and the side of the electrical module 20 are exposed, and the rest of the cables are either hidden in the column 11 or hidden behind the cover 30, which is more beautiful, and after the branch cables come out from the front surface of the column 11, the front end of the electrical module 20 protrudes from the column 11, so that the exposed cables between the front surface of the column 11 and the side of the electrical module 20 are basically located in the blind spot of vision, and the impact on the appearance can be basically ignored.

[0057] When the electrical module 20 needs maintenance, the cover 30 is opened or removed, the branch cable is removed from the wiring port 24, and then the electrical module 20 is removed, and the electrical module 20 can be pulled out forward. Since the wire hole 1111 is opened on the front surface of the column 11, the welding of the branch cable and the main cable makes the branch cable tilt forward without affecting the electrical module 20; after the electrical module 20 is maintained, the electrical module 20 is installed on the cabinet 10 and locked on the column 11 through the hanging ear 23. When the hanging ear 23 abuts against the front surface of the column 11, the electrical module 20 is installed in place. Since the protruding portion protrudes from the front surface of the column 11, the branch cable coming out of the wire hole 1111 can be directly connected to the wiring port 24 on the protruding portion, which is convenient to operate.

[0058] It can be seen that, by adopting the present technical solution, the electrical module 20 will basically not contact the branch cable when being pulled out, thereby ensuring the stable connection between the branch cable and the main cable, and making the electrical module 20 smoothly pulled out during maintenance; the structure of the present technical solution also makes it convenient to connect or disconnect the electrical module 20 and the branch cable, and the cable as a whole is basically hidden, which is more beautiful; in addition, in the present solution, there is no need to set up a wire binding rack, and the cable is directly accommodated by the space in the column 11, which is more clever. In practical applications, it also involves the welding of the branch cable and the main cable and the problem of the branch cable passing through the wire hole 1111. In the present solution, the main cable can be placed through the notch of the wiring trough 111, and then the branch cable and the main cable can be welded. After the welding is completed, the branch cables can be passed through each wire hole 1111 one by one. Therefore, the present solution can provide enough space for operators to weld and thread, and the operation is convenient.
