The plurality of copper bars may correspond to one of the three phases ABC and the N phase (neutral line), for example. The plurality of copper bars in the vertical row unit in the prior art are not completely isolated, and arcing is prone to occur. Therefore, it is necessary to improve the isolation between the copper bars connected to each phase. Utility Model Content

[0003] At least some embodiments of the present disclosure provide a vertical row unit for an electrical cabinet, comprising: a plurality of connection rows arranged in a left-right direction; a plurality of housing units arranged in an up-down direction perpendicular to the left-right direction, and each housing unit comprises a bottom plate and a cover plate, the bottom plate and the cover plate together defining a plurality of wiring spaces, wherein each connection row extends through one of the plurality of wiring spaces of the plurality of housing units in the up-down direction. The bottom plate has a bottom plate base and a plurality of bottom plate partitions. The bottom plate partitions extend from the bottom plate base toward the cover plate in a front-to-back direction perpendicular to the left-right direction and the up-to-down direction and extend in the up-to-down direction. The cover plate comprises a cover plate base and a plurality of cover plate partitions, the cover plate partitions extend from the cover plate base toward the bottom plate in the front-to-back direction and extend in the up-to-down direction. The plurality of bottom plate partitions and the plurality of cover plate partitions together separate the plurality of wiring spaces, and the projections of each bottom plate partition and the corresponding cover plate partition in the left-to-right direction at least partially overlap.

[0004] For example, in some embodiments, the cover base has an upper cover end and a lower cover end opposite in the up-down direction. The plurality of housing units include at least three housing units, wherein the housing unit located in the middle is the middle housing unit, and the housing units located at both ends of the plurality of housing units are respectively the first end housing unit and the second end housing unit. The cover bases of the middle housing unit and the first end housing unit each have a first isolation protrusion. The first isolation protrusion extends outwardly from the lower cover end of the cover base of the corresponding housing unit in the up-down direction and in the left-right direction. The cover bases of the middle housing unit and the second end housing unit each have a second isolation protrusion. The second isolation protrusion extends outwardly from the upper cover end of the cover base of the corresponding housing unit in the up-down direction and in the left-right direction. The projections of the adjacent first isolation protrusion and the second isolation protrusion in the front-to-back direction at least partially overlap. The first isolation protrusion and the second isolation protrusion are configured so that the cover of the middle housing unit can be removed by pulling out the cover of the middle housing unit in the front-to-back direction in the direction away from the plurality of wiring spaces, and then moving in the up-to-down direction, without removing the cover of other housing units.

[0005] For example, in some embodiments, the base of the cover plate has a flat outer surface facing away from the plurality of wiring spaces in the front-to-back direction. The first isolation protrusion has a flat stop surface parallel to the flat outer surface and facing away from the plurality of wiring spaces, and the flat stop surface is offset from the flat outer surface. The second isolation protrusion extends a first height from the lower end of the cover plate and has a first thickness in the front-to-back direction, and the surface of the second isolation protrusion facing away from the plurality of wiring spaces is flush with the flat outer surface. The projections of the adjacent first isolation protrusion and the second isolation protrusion in the front-to-back direction overlap by an overlapping height in the up-down direction. The first height is greater than twice the overlapping height, and the offset distance is greater than twice the first thickness.

[0006] For example, in some embodiments, the cover plate partition wall has an upper end of the cover plate partition wall and a lower end of the cover plate partition wall that are opposite in the up-down direction. The plurality of shell units include at least three shell units, wherein the shell unit located in the middle is the middle shell unit, and the shell units located at both ends of the plurality of shell units are respectively the first end shell unit and the second end shell unit. The cover plate partition walls of the middle shell unit and the first end shell unit each have a first isolation terminal section at the lower end of the cover plate partition wall. The cover plate partition walls of the middle shell unit and the second end shell unit each have a second isolation terminal section at the upper end of the cover plate partition wall. The projections of the adjacent first isolation terminal sections and the second isolation terminal sections in the left-right direction at least partially overlap.

[0007] For example, in some embodiments, the bottom plate base has at least one bottom plate support groove extending in the up-down direction at each wiring space. The cover plate base has at least one cover plate support groove extending in the up-down direction at each wiring space. The connecting row has a first support protrusion and a second support protrusion, and the first support protrusion and the second support protrusion extend in the up-down direction. The first support protrusion is accommodated in the bottom plate support groove, and the second support protrusion is accommodated in the cover plate support groove.

[0008] For example, in some embodiments, the cover plate base is provided with a through hole that penetrates the cover plate base in the front-to-back direction, and the through hole is used for a clamp configured to clamp the first support protrusion of the connection row to pass through.

[0009] For example, in some embodiments, the bottom plate partition wall has a bottom plate partition wall upper end and a bottom plate partition wall lower end opposite in the up-down direction. The plurality of housing units include at least three housing units, wherein the housing unit located in the middle is the middle housing unit, and the housing units located at both ends of the plurality of housing units are respectively the first end housing unit and the second end housing unit. The bottom plate partition walls of the middle housing unit and the first end housing unit each have a third isolation terminal section at the bottom plate partition wall lower end. The bottom plate partition walls of the middle housing unit and the second end housing unit each have a fourth isolation terminal section at the top end of the bottom plate partition wall. The projections of the adjacent third isolation terminal sections and the fourth isolation terminal sections in the left-right direction at least partially overlap.

[0010] For example, in some embodiments, the bottom plate base has a bottom plate upper end and a bottom plate lower end opposite in the up-down direction. The plurality of housing units include at least three housing units, wherein the housing unit located in the middle is the middle housing unit, and the housing units located at both ends of the plurality of housing units are respectively the first end housing unit and the second end housing unit. The bottom plate base of the middle housing unit and the first end housing unit each has one of the pin structure and the hole structure at the bottom plate lower end. The bottom plate base of the middle housing unit and the second end housing unit each has the other of the pin structure and the hole structure at the bottom plate upper end. The pin structure and the hole structure extend in the front-back direction. Adjacent pin structures and hole structures form a hole-pin fit with each other.

[0011] For example, in some embodiments, the vertical row unit further includes: a first pillar extending in the up-down direction; a second pillar extending in the up-down direction. A plurality of housing units are mounted between the first pillar and the second pillar. The first pillar is provided with a first mounting hole, the second pillar is provided with a second mounting hole, the bottom plate is provided with a third mounting hole aligned with the first mounting hole and a fourth mounting hole aligned with the second mounting hole, and is provided with a plurality of fifth mounting holes, and the cover plate is provided with a plurality of sixth mounting holes respectively aligned with the plurality of fifth mounting holes.

[0012] For example, in some embodiments, the housing unit located at the lower end of the plurality of housing units is a second end housing unit. The second end housing unit is provided with a support base for supporting the connection row in the vertical direction at one end away from the middle housing unit in the vertical direction. The support base is provided with a vent hole penetrating in the vertical direction at each wiring space.

[0013] For example, in some embodiments, the housing unit located at the lower end of the plurality of housing units is a first end housing unit. The connection row extends beyond the first end housing unit in the up-down direction. The vertical row unit also includes a cover unit for covering the portion of the connection row extending beyond the first end housing unit, the cover unit having a first cover plate, a second cover plate opposite to the first cover plate in the left-right direction, a third cover plate connecting the first cover plate and the second cover plate, and a plurality of fourth cover plates arranged between the second cover plate and the third cover plate and parallel to the second cover plate and the third cover plate. The first cover plate covers a plurality of connection rows in the up-down direction, the second cover plate and the third cover plate cover a plurality of connection rows in the left-right direction, and a plurality of fourth cover plates separate the plurality of connection rows. Each fourth cover plate has a first mating portion, and the first end housing unit has a plurality of second mating portions.

[0069] Hereinafter, a vertical row unit and an electrical cabinet according to embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0070] Figure 1 shows a rear perspective view of an electrical cabinet according to an embodiment of the present disclosure, Figure 2 shows a front perspective view of an electrical cabinet according to an embodiment of the present disclosure, Figure 3A Shown along Figure 2 A transverse cross-sectional view of the electrical cabinet taken along line AA. Figure 3B Shows Figure 3A A magnified view of the boxed portion. Figure 4 A rear perspective view of a vertical row unit 1 and a plurality of brackets 3 according to an embodiment of the present disclosure is shown. Figure 5 A front perspective view of a vertical row of units 1 and a plurality of brackets 3 according to an embodiment of the present disclosure is shown.

[0071] For the sake of clarity, the present disclosure uses terms such as "up", "down", "left", "right", "front" and "rear" to describe the position and orientation of components, but these terms do not limit the absolute positional relationship of the components relative to the direction of gravity or other placement directions. In this article, the longitudinal extension direction of the connection row in the vertical row unit 1 can be defined as the up-down direction, the direction in which the functional module 4 is connected to the vertical row unit 1 can be defined as the front-to-back direction, and the direction in which multiple connection rows in the vertical row unit 1 are arranged can be defined as the left-to-right direction. The up-down direction, the front-to-back direction and the left-to-right direction are perpendicular to each other. However, the present disclosure is not limited to this.

[0072] like Figure 1-Figure 5 As shown, the electrical cabinet includes a plurality of functional modules 4 ( Figure 1 and Figure 2 Only one functional module 4 is shown in the figure). The functional module 4 can be a module with a specific electrical function, such as a switch module, a control module, etc. The functional module 4 may include a plurality of electrical components and a module housing for accommodating the plurality of electrical components. For example, the module housing can enter and be withdrawn from the cabinet 2 of the electrical cabinet in the manner of a drawer, and be placed on a bracket 3 mounted to the cabinet 2. For example, the module housing can be configured to be able to slide in the front-to-back direction to enter and withdraw from the cabinet 2. The vertical row unit 1 extends in the up-and-down direction to be electrically connected to the plurality of functional modules 4. A back panel 6 and a protective door 7 are installed on one side of the mounting bracket 3 of the vertical row unit 1 to prevent the interior of the vertical row unit 1 from being accidentally accessed.

[0073] Figure 6 shows an exploded perspective view of a vertical row unit 1 according to an embodiment of the present disclosure, Figure 6 Shows Figure 7 Another exploded perspective view of the vertical row unit 1 is shown, in which only one middle housing unit 10b among the housing units is shown. Figure 8 A transverse cross-sectional view of a vertical row of units 1 according to an embodiment of the present disclosure is shown.

[0074] like Figure 6-Figure 8 As shown, the vertical row unit 1 includes a left support 15 (first support) and a right support 14 (second support), each of which extends in the up-down direction and is fixed to the cabinet body 2 of the electrical cabinet. In addition, the vertical row unit 1 also includes a plurality of housing units 10a, 10b, 10c having a bottom plate 11 and a cover plate 12 mounted to the left support 15 and the right support 14, and a connecting row 13. The bottom plate 11 is closer to the functional module 4 and the back plate 6 relative to the cover plate 12. The plurality of housing units 10a, 10b, 10c are arranged in the up-down direction, and the connecting row 13 extends in the up-down direction and penetrates the plurality of housing units 10a, 10b, 10c. The connecting row 13 may be a copper row for electrically connecting to the plurality of functional modules 4. As shown Figure 4 and Figure 6 As shown, the plurality of housing units 10a, 10b, 10c may include one or more intermediate housing units 10b located in the middle, a first end housing unit 10a located at the upper end, and a second end housing unit 10c located at the lower end. Figure 7As shown, a plurality of housing units 10a, 10b, 10c are installed between the left support 15 and the right support 14. For example, the vertical row unit 1 can be installed by first fixing the bottom plate 11 to the left support 15 and the right support 14, then snapping the connecting row 13 to the bottom plate 11, and finally fixing the cover plate 12 to the bottom plate 11. For example, the fixing of the bottom plate 11 to the left support 15 and the right support 14 and the fixing of the cover plate 12 to the bottom plate 11 can be achieved by screws. Therefore, the vertical row unit 1 can be easily installed. For example, the left support 15 is provided with a first mounting hole 151 (see Fig. 9 ), the right support 14 is provided with a second mounting hole 141. The bottom plate 11 is provided with a third mounting hole 113 aligned with the first mounting hole 151 (see Fig. 9 ) and a fourth mounting hole 111 aligned with the second mounting hole 141. In addition, the bottom plate 11 is further provided with a plurality of fifth mounting holes 112. The cover plate 12 is provided with a plurality of sixth mounting holes 121 aligned with the plurality of fifth mounting holes 112, respectively.

[0075] like Figure 8 As shown, a plurality of connection bars 13 are arranged in the left-right direction. In the present embodiment, there are four connection bars 13, namely, A-phase copper bar, B-phase copper bar, C-phase copper bar and N-phase copper bar. However, the number of connection bars 13 may be other numbers, such as 3. The bottom plate 11 and the cover plate 12 of the housing units 10a, 10b, 10c together define a plurality of wiring spaces 101. Each connection bar 13 extends through one of the plurality of wiring spaces 101 in the up-down direction.

[0076] In addition, if Figure 8 As shown, the bottom plate 11 has a bottom plate base 114 and a plurality of bottom plate partitions 115, which extend from the bottom plate base 114 toward the cover plate 12 in the front-to-back direction and extend in the up-down direction. The cover plate 12 includes a cover plate base 122 and a plurality of cover plate partitions 123, which extend from the cover plate base 122 toward the bottom plate 11 in the front-to-back direction and extend in the up-down direction. The plurality of bottom plate partitions 115 and the plurality of cover plate partitions 123 together separate the plurality of wiring spaces 101, and the projections of each bottom plate partition 115 and the corresponding cover plate partition 123 in the left-right direction at least partially overlap. Therefore, the plurality of bottom plate partitions 115 and the plurality of cover plate partitions 123 are used to form cross-isolation between the wiring spaces 101, which helps to improve the isolation performance of the plurality of wiring spaces 101, thereby preventing or reducing the occurrence of arc phase crossing.

[0077] In addition, if Figure 8As shown, in this embodiment, the connection row 13 may include a connection row body 131, a first support protrusion 132 protruding from the connection row body 131 toward the bottom plate 11 and extending in the up-down direction, and a second support protrusion 133 protruding from the connection row body 131 toward the cover plate 12 and extending in the up-down direction. The bottom plate base 114 has a bottom plate support groove 1141 extending in the up-down direction at each wiring space 101, and the cover plate base 122 has a cover plate support groove 1221 extending in the up-down direction at each wiring space 101. For example, the bottom plate support groove 1141 and the cover plate support groove 1221 can be formed by a plurality of ribs 116. The first support protrusion 132 can be accommodated in the bottom plate support groove 1141. The second support protrusion 133 can be accommodated in the cover plate support groove 1221. The bottom plate support groove 1141 and the cover plate support groove 1221 can respectively clamp and limit the first support protrusion 132 and the second support protrusion 133 to achieve support for the connection row 13. For example, the first support protrusion 132 and the second support protrusion 133 can be 10 mm thick. In addition, the connection row 13 can also include a third support protrusion 135 and a fourth support protrusion 136 protruding from the connection row body 131 toward the bottom plate 11 and the cover plate 12, respectively. The third support protrusion 135 and the fourth support protrusion 136 are respectively accommodated in the second bottom plate support groove 1142 of the bottom plate 11 and the second cover plate support groove 1222 of the cover plate 12. Therefore, the support of the bottom plate 11 and the cover plate 12 to the connection row 13 is further strengthened. When the connection row 13 is subjected to a short-time current electromotive force impact, the connection row 13 may be bent and deformed. The support of the connection row 13 by the bottom plate 11 and the cover plate 12 of the housing units 10a, 10b, 10c helps to improve the electrodynamic impact of the short-term withstand current of the vertical row units 1. For example, the housing units 10a, 10b, 10c according to this embodiment can withstand the electrodynamic impact of the short-term withstand current of 100kA. Return Figure 3A and Figure 3B , the connection row 13 can be connected to a plurality of functional modules 4 through the clamp 5 . The clamp 5 passes through the bottom plate 11 and clamps the first support protrusion 132 of the connection row 13 .

[0078] It should be noted that the present disclosure does not limit the shape of the connection row 13 . Fig.18 FIG. 2 shows a transverse cross-sectional view of a vertical row unit 1' according to another embodiment of the present disclosure. Fig.18 As shown, Figure 8 The difference from the vertical row of units 1 ′ shown is that in this embodiment, the cross section of the connecting row 13 ′ is rectangular.

[0079] Fig. 9 A rear perspective view showing two pillars 14, 15 of a vertical row unit 1 and a bottom plate 11 of an intermediate housing unit 10b according to an embodiment of the present disclosure is shown, Fig.10 FIG. 1 shows a front perspective view of the bottom plate 11 of three intermediate housing units 10b of a vertical row of units 1 according to an embodiment of the present disclosure. Fig. 9 As shown, the bottom plate 11 has a plurality of ribs 116, which are used to form the bottom plate support groove 1141 and the second bottom plate support groove 1142. Fig.10 As shown, the bottom plate base 114 has a bottom plate upper end and a bottom plate lower end opposite in the up-down direction. The bottom plate base 114 of the intermediate housing unit 10b is provided with a plurality of pin structures 1144 extending in the front-to-back direction at the bottom plate upper end. The bottom plate base 114 of the intermediate housing unit 10b is provided with a plurality of hole structures 1143 extending in the front-to-back direction at the bottom plate lower end. The hole structures 1143 and the corresponding pin structures 1144 form a hole-pin fit, and the bottom plates 11 of the plurality of intermediate housing units 10b can be spliced ​​with each other to be connected together through the hole-pin fit. In addition, the bottom plate base 114 of the first end housing unit 10a can also be provided with the same hole structure 1143 as the intermediate housing unit 10b, and the bottom plate base 114 of the second end housing unit 10c can also be provided with the same pin structure 1144 as the intermediate housing unit 10b. Therefore, the bottom plate 11 of the first end shell unit 10a can be connected to the middle shell unit 10b adjacent to it on its lower side by hole-pin matching, and the bottom plate 11 of the second end shell unit 10c can be connected to the middle shell unit 10b adjacent to it on its upper side by hole-pin matching. It should be noted that, in other embodiments, a pin structure 1144 can be provided at the upper end of the bottom plate, and a hole structure 1143 can be provided at the lower end of the bottom plate. In other embodiments, the hole-pin matching may not be used, and other matching may be used to connect the bottom plates 11 of multiple shell units 10a, 10b, 10c, for example, other convex-concave matching. The use of hole-pin matching can avoid gaps between the upper and lower bottom plates 11 caused by part deformation and assembly errors.

[0080] Fig.11 FIG. 1 shows a partial view of adjacent bottom plates 11 of two middle housing units 10b of a vertical row of units 1 according to an embodiment of the present disclosure. The bottom plate partition wall 115 has a bottom plate partition wall upper end and a bottom plate partition wall lower end opposite to each other in the up-down direction. Fig.11 As shown, the bottom plate partition wall 115 of the middle housing unit 10b has a third isolation terminal section 1151 and a fourth isolation terminal section 1152 at the bottom plate partition wall lower end and the top plate partition wall, respectively. The projections of the adjacent third isolation terminal sections 1151 and the fourth isolation terminal sections 1152 in the left-right direction at least partially overlap. Therefore, the adjacent third isolation terminal sections 1151 and the fourth isolation terminal sections 1152 improve the isolation performance between the adjacent wiring spaces 101 in the left-right direction of the vertical row unit 1.

[0081] In addition, the bottom plate partition wall 115 of the first end housing unit 10a may also be provided with the third isolation terminal section 1151 which is the same as that of the middle housing unit 10b, and the bottom plate partition wall 115 of the second end housing unit 10c may also be provided with the fourth isolation terminal section 1152 which is the same as that of the middle housing unit 10b. Therefore, the third isolation terminal section 1151 of the first end housing unit 10a may at least partially overlap with the projection of the fourth isolation terminal section 1152 of the middle housing unit 10b adjacent thereto at its lower side in the left-right direction, and the fourth isolation terminal section 1152 of the second end housing unit 10c may at least partially overlap with the projection of the third isolation terminal section 1151 of the middle housing unit 10b adjacent thereto at its upper side in the left-right direction.

[0082] like Fig. 9 , Fig.10 , Figure 3A and Figure 3B As shown, the bottom plate base 114 is further provided with a through hole 1145 penetrating the cover plate base 114 in the front-to-back direction, and the through hole 1145 is used for the chuck 5 to pass through.

Fig.14A FIG. 12 shows another partial view of the three intermediate housing units 10 b , wherein the cover plate 12 of the middle intermediate housing unit 10 b is further lifted upward. Fig. 14B Shows Fig.14A A partial enlarged view of the boxed portion in FIG. Figures 12A-14B The step of removing the cover plate 12 of one of the middle housing units 10 b in the vertical row of units 1 according to an embodiment of the present disclosure is shown.

[0084] The cover base 122 has a cover upper end and a cover lower end which are opposite to each other in the up-down direction. Figures 12A-14BAs shown, the cover plate base 122 of the intermediate housing unit 10b is provided with a first isolation protrusion 1223 and a second isolation protrusion 1224 at the lower end and the upper end of the cover plate, respectively. The first isolation protrusion 1223 extends outwardly in the up-down direction and in the left-right direction from the lower end of the cover plate of the corresponding cover plate base 122. The second isolation protrusion 1224 extends outwardly in the up-down direction and in the left-right direction from the upper end of the cover plate of the corresponding cover plate base 122. The projections of adjacent first isolation protrusions 1223 and second isolation protrusions 1224 in the front-to-back direction at least partially overlap. Therefore, the adjacent first isolation protrusions 1223 and second isolation protrusions 1224 improve the isolation performance of the vertical row unit 1 in the front-to-back direction and at the connection point of adjacent cover plates 12.

[0085] In addition, the cover plate base 122 of the first end housing unit 10a may also be provided with the same first isolation protrusion 1223 as that of the middle housing unit 10b, and the cover plate base 122 of the second end housing unit 10c may also be provided with the same second isolation protrusion 1224 as that of the middle housing unit 10b. Therefore, the first isolation protrusion 1223 of the first end housing unit 10a may at least partially overlap with the projection of the second isolation protrusion 1224 of the middle housing unit 10b adjacent thereto at its lower side in the front-to-back direction, and the second isolation protrusion 1224 of the second end housing unit 10c may at least partially overlap with the projection of the first isolation protrusion 1223 of the middle housing unit 10b adjacent thereto at its upper side in the front-to-back direction.

[0086] The projections of the first isolation protrusion 1223 and the second isolation protrusion 1224 in the front-to-back direction at least partially overlap, making it difficult to independently remove the cover plate 12 of any one of the intermediate housing units 10b without removing the cover plates 12 of the other housing units. In the present embodiment, the first isolation protrusion 1223 and the second isolation protrusion 1224 are configured so that the cover plate 12 of the intermediate housing unit 10b can be pulled out in the front-to-back direction in a direction away from the plurality of wiring spaces 101 (see Fig.13A and Fig. 13B ), and then move in the up and down directions (see Fig.14A and Fig. 14B ) to remove the cover plate 12 of the middle housing unit 10b without removing the cover plates 12 of other housing units.

[0087] like Fig. 12A and Fig. 12BAs shown, the three intermediate housing units 10b are in a state of installation completion. The second isolation protrusion 1224 of the cover plate 12 of the second intermediate housing unit 10b in the middle partially overlaps with the projection of the first isolation protrusion 1223 of the cover plate 12 of the first intermediate housing unit 10b above it in the front-to-back direction. The first isolation protrusion 1223 of the cover plate 12 of the second intermediate housing unit 10b in the middle partially overlaps with the projection of the second isolation protrusion 1224 of the cover plate 12 of the third intermediate housing unit 10b below it in the front-to-back direction. Fig.13A and Fig. 13B As shown, the cover plate 12 of the second intermediate housing unit 10b is pulled out backward and outward. Fig.14A and Fig. 14B As shown, the cover plate 12 of the second intermediate housing unit 10b is then translated upward and lifted. Finally, the cover plate 12 of the second intermediate housing unit 10b is pulled outward again to remove the cover plate 12 of the second intermediate housing unit 10b without removing the cover plates 12 of other housing units. Of course, the cover plate 12 can be installed in the reverse order of removing the cover plate 12 of the intermediate housing unit 10b.

[0088] like Figures 12A-14B As shown, the cover base 122 has a flat outer surface 1225 facing away from the plurality of wiring spaces 101 in the front-to-back direction. The first isolation protrusion 1223 has a flat stop surface 1226 parallel to the flat outer surface 1225 and facing away from the plurality of wiring spaces 101, and the flat stop surface 1226 is offset from the flat outer surface 1225. The second isolation protrusion 1224 extends from the lower end of the cover to a first height and has a first thickness in the front-to-back direction. The surface of the second isolation protrusion 1224 facing away from the plurality of wiring spaces 101 is flush with the flat outer surface 1225. The projections of the adjacent first isolation protrusion 1223 and second isolation protrusion 1224 in the front-to-back direction overlap by an overlapping height in the up-down direction. For example, the first height is greater than 2 times the overlapping height, and the offset distance is greater than 2 times the first thickness. A foolproof mark 1227 is provided on the flat outer surface 1225 of the intermediate housing unit 10b to indicate the installation direction of the intermediate housing unit 10b.

[0089] Fig.15 FIG. 1 shows a partial view of adjacent cover plates 12 of two intermediate housing units 10b of a vertical row of units 1 according to an embodiment of the present disclosure. The cover plate partition wall 123 has an upper cover plate partition wall end and a lower cover plate partition wall end that are opposite in the up-down direction. Fig.15As shown, the cover partition wall 123 of the intermediate housing unit 10b is provided with a first isolation terminal section 1231 and a second isolation terminal section 1232 at the lower end and the upper end of the cover partition wall, respectively. The projections of the adjacent first isolation terminal sections 1231 and the second isolation terminal sections 1232 in the left-right direction at least partially overlap. Therefore, the adjacent first isolation terminal sections 1231 and the second isolation terminal sections 1232 improve the isolation performance between the adjacent wiring spaces 101 in the left-right direction of the vertical row unit 1. For example, the first isolation terminal section 1231 is a part of the cover partition wall body, and the second isolation terminal section 1232 is a strip section that is offset from the cover partition wall body in the left-right direction and protrudes in the up-down direction.

[0090] In addition, the cover plate partition wall 123 of the first end housing unit 10a may also be provided with the same first isolation terminal section 1231 as that of the middle housing unit 10b, and the cover plate partition wall 123 of the second end housing unit 10c may also be provided with the same second isolation terminal section 1232 as that of the middle housing unit 10b. Therefore, the first isolation terminal section 1231 of the first end housing unit 10a may at least partially overlap with the projection of the second isolation terminal section 1232 of the middle housing unit 10b adjacent thereto at its lower side in the left-right direction, and the second isolation terminal section 1232 of the second end housing unit 10c may at least partially overlap with the projection of the first isolation terminal section 1231 of the middle housing unit 10b adjacent thereto at its upper side in the left-right direction.

[0091] Fig.16 FIG. 1 shows a partial view of a vertical row unit 1 at a second end housing unit 10c according to an embodiment of the present disclosure. Fig.16 In the figure, the cover plate 12 of the second end housing unit 10c is removed for clarity. Fig.16 As shown, the second end housing unit 10c is provided with a support base 1181 for supporting the connection row 13 in the up-down direction at one end (i.e., the lower end) away from the middle housing unit 10b in the up-down direction. The support base 1181 is provided with a vent 1182 penetrating in the up-down direction at each wiring space 101. For example, the height of the support base is greater than 20 mm to meet the 15 mm electrical clearance requirement of the impulse withstand voltage 12 kV. For example, the opening width of the vent 1182 is less than 12 mm to meet the IP2X requirement. The vent 1182 is conducive to increasing the air intake in the wiring space 1101 of the vertical row unit and reducing the temperature of the wiring space 1101.

[0092] Fig.17 FIG. 2 shows a partial view of a vertical row unit 1 at a first end housing unit 10a according to an embodiment of the present disclosure. Fig.17As shown, the connection row 13 extends beyond the first end housing unit 10a in the up-down direction. In addition, the vertical row unit 1 also includes a cover unit 16 for covering the portion of the connection row 13 extending beyond the first end housing unit 10a. The cover unit 16 has a first cover plate 161, a second cover plate 162 opposite to the first cover plate 161 in the left-right direction, a third cover plate 163 connecting the first cover plate 161 and the cover plate, and a plurality of fourth cover plates 164 arranged between the first cover plate 161 and the second cover plate 162 and parallel to the first cover plate 161 and the second cover plate 162. The third cover plate 163 covers the plurality of connection rows 13 from the upper side, the first cover plate 161 and the second cover plate 162 cover the plurality of connection rows 13 in the left-right direction, and the plurality of fourth cover plates 164 separate the plurality of connection rows 13. The cover unit 16 helps prevent foreign objects such as screws from falling into the wiring space 1101 of the vertical row unit 1. Each fourth cover plate 164 has a first mating portion 1641. The first end housing unit 10a has a plurality of second mating portions 1642. The first mating portion 1641 and the corresponding second mating portion 1642 form a hole-pin fit. For example, in this example, the first mating portion 1641 is a pin-shaped guide protrusion extending in the front-to-back direction. The second mating portion 1642 is a hole-shaped guide groove extending in the front-to-back direction. In another example, the first mating portion 1641 is a hole-shaped guide groove extending in the front-to-back direction. The second mating portion 1642 is a pin-shaped guide protrusion extending in the front-to-back direction.
