[0032] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0033] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above and over", and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below and under", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0035] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] As Figures 1 to 3 shown, on the one hand, this embodiment provides a copper bar assembly structure for a switch cabinet, which is used to be arranged inside the switch cabinet. Among them, the first direction takes the vertical direction as an example, and the second direction takes the horizontal direction as an example. The copper bar assembly structure of the switch cabinet includes an insulating member 3 and at least three copper bars arranged at intervals. The insulating member 3 is arranged corresponding to the copper bars one by one. The copper bar includes a first part arranged inside the insulating member 3 and a second part connected to the first part and extending outside the insulating member 3; there is a fan-shaped transition area at the connection of the first part and the second part of the outermost copper bar; the distance between the first parts of every two adjacent copper bars is less than the distance between the second parts of these two copper bars.

[0037] By arranging the first part of the copper bar inside the insulating member 3, it is not necessary to consider the safety clearance when setting the first part of the copper bar, and the distance between the first parts of two adjacent copper bars is set to be smaller, so that it can be applicable to be installed in a switch cabinet with a relatively narrow width; the copper bar also has a second part extending outside the insulating member 3, and there is a fan-shaped transition area at the connection of the first part and the second part of the outermost copper bar, so that the first part and the second part of the outermost copper bar extend in different directions, and the distance between the second parts of every two adjacent copper bars is greater than the distance between the first parts of these two copper bars. The second parts of two adjacent copper bars can maintain a safety clearance, without the need to add insulating partitions, saving materials and having simple and efficient installation. It also effectively avoids current leakage or short circuit caused by too small a distance between two adjacent copper bars, and has a relatively high safety level.

[0038] Specifically, the insulating member 3 can be a contact box; the contact box is a key component in the switch cabinet. Copper bars need to be installed inside the switch cabinet as current-carrying carriers. The contact box is composed of a terminal, a contact, a disconnector, etc. The terminal connects the main circuit and the control circuit in the switch cabinet. The contact can convert and transmit the electric energy in the switch cabinet to the load, and the disconnector can isolate the main circuit and the control circuit to ensure the safety of the operator. The main function of the contact box is insulation shielding to realize the connection between the copper bar and the contact. In other embodiments, the insulating member 3 can also be a sleeve made of insulating material, and the sleeve is used to be sleeved outside the copper bar to play a role of insulation isolation and protection.

[0039] One end of the copper bar is disposed within the insulating member 3. To enable the other end of the copper bar to connect to components at different positions, optionally, the copper bar further includes a third portion. The second portion is connected between the first portion and the third portion. The third portion forms a preset angle with the extending direction of the second portion. The distance between the third portions of two adjacent copper bars is equal to the distance between the second portions of these two copper bars.

[0040] By setting the third portion to have a different extending direction from the second portion, one end of the third portion is connected to the second portion, and the other end of the third portion can extend obliquely to components at other positions, thereby minimizing the length of the copper bar used. Moreover, the distance between the third portions of two adjacent copper bars is the same as the distance between the second portions of these two copper bars, ensuring a safety gap between the third portions of adjacent copper bars. The specific value of the preset angle can be adjusted according to the installation positions of the actual components, and the copper bar is bent according to the preset angle to form the third portion. The extending directions of the third portions of two adjacent copper bars can be the same or different.

[0041] In this embodiment, the copper bars are arranged in two rows, namely the upper copper bar branch 10 and the lower copper bar branch 20. The upper copper bar branch 10 and the lower copper bar branch 20 are arranged at intervals in the vertical direction. Both the upper copper bar branch 10 and the lower copper bar branch 20 include three copper bars arranged at intervals in the horizontal direction.

[0042] By arranging the upper copper bar branch 10 and the lower copper bar branch 20, the number of copper bars can be increased. Correspondingly, the insulating members 3 are also arranged in two rows in the vertical direction. The first row of insulating members corresponds to the upper copper bar branch 10, and the second row of insulating members corresponds to the lower copper bar branch 20. In other embodiments, only three copper bars can be arranged in a row; or nine copper bars can be arranged in three rows.

[0043] It can be understood that for three copper bars in each row, one copper bar is placed in the middle, and the other two copper bars are respectively placed on both sides of this middle copper bar. There is a fan-shaped transition area at the connection between the first portion and the second portion of the copper bar placed on the outer side. The extending directions of the first portion and the second portion of the copper bar placed in the middle are the same. The extending directions of the first portion and the second portion of the copper bar placed on the outer side intersect and form an angle. By arranging the two outer copper bars to extend obliquely, on the basis of ensuring a safety gap between the second portions of the three copper bars, the distance between the first portions of the three copper bars is reduced, thereby reducing the requirement for the width of the switchgear.

[0044] Specifically, the upper copper row branch 10 includes a first copper row 11, a second copper row 12, and a third copper row 13. The first copper row 11, the second copper row 12, and the third copper row 13 are arranged at intervals in the horizontal direction, and the second copper row 12 is located between the first copper row 11 and the third copper row 13. The first part of the first copper row 11 extends obliquely towards the direction of the first part of the second copper row 12, and the first part of the third copper row 13 extends obliquely towards the direction of the first part of the second copper row 12. The second part of the first copper row 11, the second part of the second copper row 12, and the second part of the third copper row 13 are parallel to each other.

[0045] By setting the extending directions of the second parts of the first copper row 11, the second copper row 12, and the third copper row 13 to be parallel, it is ensured that a safe gap can be maintained between the second parts of adjacent copper rows. By setting the first parts of the first copper row 11 and the third copper row 13 to extend obliquely towards the direction of the second copper row 12, the distance between the first parts of two adjacent copper rows in the upper copper row branch 10 can be reduced, thereby reducing the requirement for the width of the switchgear cabinet.

[0046] Among them, the extending directions of the first part and the second part of the first copper row 11 intersect and form an included angle θ. The included angle θ is less than 180 degrees. Optionally, the value range of the included angle θ is 105 degrees to 165 degrees.

[0047] In this embodiment, the first copper row 11 is bent to form the first part and the second part of the first copper row 11. There is a fan-shaped transition area at the connection between the first part and the second part of the first copper row 11. By bending the copper row to form a fan-shaped transition area, the bending angle is relatively large, which has the characteristics of high strength, and it ensures that the contact area between the bent part and the air is sufficient, enabling better heat dissipation. It should be noted that there is a connection port on the insulating part 3, and the width of the fan-shaped transition area needs to be slightly smaller than the connection port of the insulating part 3 to ensure that the first part of the copper row can be placed into the insulating part 3 from the connection port.

[0048] Among them, the extending directions of the first part and the second part of the second copper row 12 are the same. In this embodiment, both the first part and the second part of the second copper row 12 extend in the vertical direction. By setting the extending directions of the first part and the second part of the second copper row 12 to be the same, the first part of the second copper row 12 maintains the same distance from the first copper row 11 and the third copper row 13 respectively.

[0049] Specifically refer to Figure 2 and Figure 3, the first copper bar 11, the second copper bar 12, and the third copper bar 13 all have a third part; taking the first copper bar 11 as an example, A represents the first part of the first copper bar 11, B represents the second part of the first copper bar 11, D represents the fan-shaped transition area of the first copper bar 11; C represents the third part of the first copper bar 11. The extending directions of the third parts (at C) of the first copper bar 11, the second copper bar 12, and the third copper bar 13 are all different.

[0050] Optionally, the first parts of the first copper bar 11 and the third copper bar 13 are symmetrically arranged on both sides of the first part of the second copper bar 12. In this embodiment, the extending directions of the first part and the second part of the third copper bar 13 intersect and form an angle β; the angle β is less than 180 degrees; after the third copper bar 13 is bent, the first part and the second part of the third copper bar 13 are formed; there is a fan-shaped transition area at the connection between the first part and the second part of the third copper bar 13. Optionally, the value range of the angle β is 105 degrees to 165 degrees; the angle β is equal to the value of the angle θ.

[0051] In other embodiments, if the insulating part 3 is a sleeve, the value ranges of the angle θ and the angle β will be restricted by the inner diameter of the sleeve; for example, when the first part of the first copper bar 11 is in contact with the inner wall of the sleeve, the angle θ can reach the maximum value or the minimum value.

[0052] Correspondingly, the first row of insulating parts includes a first insulating part 31, a second insulating part 32, and a third insulating part 33. The first part of the first copper bar 11 is arranged in the first insulating part 31, the first part of the second copper bar 12 is arranged in the second insulating part 32, and the first part of the third copper bar 13 is arranged in the third insulating part 33.

[0053] Specifically, the lower copper bar branch 20 includes a fourth copper bar 21, a fifth copper bar 22, and a sixth copper bar 23. The fourth copper bar 21, the fifth copper bar 22, and the sixth copper bar 23 are arranged at intervals in the horizontal direction, and the fifth copper bar 22 is located between the fourth copper bar 21 and the sixth copper bar 23; the first part of the fourth copper bar 21 extends obliquely towards the direction of the first part of the fifth copper bar 22, the first part of the sixth copper bar 23 extends towards the direction of the first part of the fifth copper bar 22, and the second parts of the fourth copper bar 21, the fifth copper bar 22, and the sixth copper bar 23 are parallel to each other. By setting the extending directions of the second parts of the fourth copper bar 21, the fifth copper bar 22, and the sixth copper bar 23 to be parallel, it is ensured that a safe gap can be maintained between the second parts of adjacent copper bars; by setting the first parts of the fourth copper bar 21 and the sixth copper bar 23 to extend obliquely towards the direction of the fifth copper bar 22, the distance between the first parts of two adjacent copper bars in the lower copper bar branch 20 can be reduced, thereby reducing the requirement for the width of the switchgear.

[0054] Among them, the first part and the second part of the fourth copper row 21 extend in intersecting directions and form an included angle α; the included angle α is less than 180 degrees. Optionally, the value range of the included angle α is 105 degrees to 165 degrees. In this embodiment, after the fourth copper row 21 is bent, the first part and the second part of the fourth copper row 21 are formed, and a fan-shaped transition area is provided at the connection between the first part and the second part of the fourth copper row 21.

[0055] Optionally, the first part of the fourth copper row 21 and the first part of the sixth copper row 23 are symmetrically arranged on both sides of the first part of the fifth copper row 22. In this embodiment, the first part and the second part of the sixth copper row 23 extend in intersecting directions and form an included angle γ; the included angle γ is less than 180 degrees; after the sixth copper row 23 is bent, the first part and the second part of the sixth copper row 23 are formed; a fan-shaped transition area is provided at the connection between the first part and the second part of the sixth copper row 23. Optionally, the value range of the included angle γ is 105 degrees to 165 degrees; the included angle γ has the same value as the included angle α.

[0056] Among them, the first part and the second part of the fifth copper row 22 extend in the same direction and both extend in the vertical direction.

[0057] Correspondingly, the second row of insulating parts includes a fourth insulating part 34, a fifth insulating part 35 and a sixth insulating part 36. The first part of the fourth copper row 21 is arranged in the fourth insulating part 34, the first part of the fifth copper row 22 is arranged in the fifth insulating part 35, and the first part of the sixth copper row 23 is arranged in the sixth insulating part 36.

[0058] In this embodiment, the second parts of the copper rows of the upper copper row branch 10 and the lower copper row branch 20 both extend in the vertical direction; the included angles θ, β, α and γ have the same value.

[0059] Optionally, the first row of insulating parts and the second row of insulating parts are arranged at intervals in the vertical direction. The first row of insulating parts is provided with connection ports on the sides opposite to the second row of insulating parts. The first parts of the copper rows are placed in the insulating part 3 from the connection ports. That is, the first row of insulating parts is located above the second row of insulating parts. The first row of insulating parts is provided with a connection port at the top. The first part of the copper row of the upper copper row branch 10 is arranged in the first row of insulating parts from the connection port at the top; the second row of insulating parts is provided with a connection port at the bottom.
