[0002] Many industrial devices require driving workpieces or worktables to perform multi-degree-of-freedom motion and precisely positioning them, such as the worktable and mask stages in lithography machines. To achieve multi-degree-of-freedom motion and precise positioning, multiple drive motors are needed to drive the equipment. The increase in the number of drive motors correspondingly increases the number of power cables in the equipment. Especially for highly integrated ultra-precision motion systems, a large number of cables requires a lot of space, is inconvenient to manage, and unstable cable fixing may affect the normal operation of the equipment. Summary of the Invention

[0009] Optionally, the power transmission unit is covered with a first outer insulating layer; and / or, when there are multiple power transmission units, the entire assembly formed by the multiple power transmission units is covered with a first outer insulating layer.

Detailed Implementation
[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0026] This embodiment provides a cable strip 30, such as Figure 3 As shown, it includes a power transmission unit, which includes multiple conductive modules 100. Each conductive module 100 includes multiple stacked conductive bodies, and each adjacent conductive body is separated by an insulating layer 140; an insulating module 200 is provided between two adjacent conductive modules 100.
[0027] This embodiment also provides a power line device, such as... Figure 1 and Figure 2 As shown, it includes an input connector 20, multiple output connectors 40, multiple sets of connection terminals 50 and the aforementioned cable tray 30. The input connector 20 is connected to the input end of the conductive module 100 in the cable tray 30; the multiple output connectors 40 are connected one-to-one between the output ends of the multiple conductive modules 100 and the multiple sets of connection terminals 50.
[0028] The cable tray 30 and power line device provided in this embodiment include a power transmission unit comprising multiple conductive modules 100 for transmitting power to different drive motors 60 (here, drive motor 60 is only used as an example, but it can also be other drive components) and an insulating module 200 for isolating and insulating adjacent conductive modules 100. Each conductive module 100 includes multiple conductors for connecting and transmitting power to different types of wires, and also includes a secondary insulating layer 140 for isolating and insulating adjacent conductors. The power line device includes an input connector 20 for connecting the power supply 10 to the cable tray 30, a connection terminal 50 for connecting to the drive motor 60, and an output connector 40 for connecting the cable tray 30 to the connection terminal 50. Specifically, the conductors can be made of metal materials such as pure copper or pure aluminum.
[0029] Specifically, the output end of the input connector 20 is electrically connected one-to-one with the input ends of multiple conductive modules 100 in the busbar 30; the input end of the output connector 40 is electrically connected one-to-one with the output ends of multiple conductive modules 100 in the busbar 30; and multiple connection terminals 50 are electrically connected one-to-one with the output ends of multiple output connectors 40. Thus, one output end of the input connector 20, one conductive module 100, one output connector 40, and a set of connection terminals 50 are sequentially connected to form a power transmission path. Therefore, the busbar 30 includes multiple power transmission paths, the same number as the number of conductive modules 100. In use, such as... Figure 1 As shown, when the input connector 20 is connected to the power supply 10 and the connection terminal 50 is connected to the drive motor 60, the power supply 10 can transmit power to the corresponding drive motor 60 through different transmission circuits, and the drive motor 60 uses electricity as a power source to perform driving operations.
[0030] In this design, multiple conductive modules 100 are integrated into a single cable strip 30, which is tightly connected to the insulating module 200. The cable strip 30 is small in size, allowing it to power multiple drive motors 60 from a single unit while minimizing space requirements and improving operator convenience. Furthermore, as a single unit, the conductive modules 100 remain fixed within the cable strip, ensuring high stability and conductivity during operation. The fixed position of the cable strip 30 minimizes interference with the drive motors 60 and their driven objects, thus ensuring the normal operation of the drive motors 60 and the equipment on which they are mounted. Additionally, because the conductive cross-sectional area of the conductor is much larger than that of the wire in a cable, the conductor generates less heat under the same voltage. Consequently, the cable strip 30 generates less heat, minimizing its impact on the ambient temperature. For ultra-precision measurement systems sensitive to ambient temperature, the cable strip 30 effectively ensures measurement accuracy.
[0031] Optionally, in this embodiment, the multiple conductive modules 100 and insulating modules 200 in the power transmission unit can be stacked. This is a specific arrangement of the multiple conductive modules 100 in the power transmission unit. The multiple conductive modules 100 are stacked sequentially, and an insulating module 200 is provided between adjacent conductive modules 100. The insulating module 200 ensures the relative independence of the conductive modules 100 in the same power transmission unit, allowing them to form different power transmission circuits that transmit power to the corresponding drive motors 60. Specifically, the number of conductive modules 100 and the number of transmission units in the transmission unit can be set according to the actual installation space. When the busbar 30 includes multiple transmission units, the multiple transmission units can be arranged sequentially, and stacked insulation layers can be provided between adjacent transmission units to reduce the contact conductivity of conductive modules 100 in adjacent transmission units, thereby affecting the independent transmission of conductive modules 100. The conductive modules 100 in the busbar 30 are arranged in the above manner. The shape of the busbar 30 can be adjusted according to the actual installation space, and the entire busbar 30 has a compact structure, occupies little space, and further reduces the requirement for installation space.
[0032] Optionally, in this embodiment, in addition to the stacked arrangement described above, the conductive modules 100 in the power transmission unit can also be arranged in a flat manner, and when there are multiple power transmission units, they are stacked, with a flat insulating layer between adjacent power transmission units. The multiple conductive modules 100 are arranged in a flat, sequential manner, and an insulating module 200 is provided between adjacent conductive modules 100. The insulating module 200 ensures the relative independence of the conductive modules 100 in the same power transmission unit, allowing them to form different power transmission circuits that transmit power to the corresponding drive motors 60. Specifically, the number of conductive modules 100 and the number of power transmission units in the power transmission unit can be set according to the actual installation space and the number of drive motors 60. When the busbar 30 includes multiple power transmission units, the multiple power transmission units can be stacked, and a flat insulation layer is provided between adjacent power transmission units to ensure the relatively independent power transmission of adjacent power transmission units. The conductive modules 100 in the busbar 30 are arranged in a flat manner, which is not only compact in structure and occupies little space, but also facilitates the processing and assembly of the busbar 30.
[0033] Optionally, in this embodiment, an intermediate shielding layer can be provided between two adjacent power transmission units, with a flat insulating layer disposed between the intermediate shielding layer and the power transmission unit. The intermediate shielding layer can shield the electromagnetic field generated during the power transmission process of the conductive module 100, thereby reducing electromagnetic interference between different power transmission units and improving the power transmission stability of the conductive module 100 and the busbar 30. Specifically, the intermediate shielding layer can be made of metal materials such as copper, aluminum, or steel. A flat insulating layer separates the intermediate shielding layer from the power transmission units above and below, providing insulation between the intermediate shielding layer and the conductors in the power transmission units, reducing the adverse effects of contact between the intermediate shielding layer and the conductors on the power transmission of the conductive module 100.
[0034] Specifically, in this embodiment, as Figure 5As shown, the insulation module 200 in the power transmission unit may include multiple stacked insulators. In the same power transmission unit, the number of conductors in each conductive module 100 and the number of insulators in each insulation module 200 are equal and correspond one-to-one from top to bottom. Conductors and insulators in the same layer form a flat layer, and a total insulation layer is provided between two adjacent flat layers. This is a specific distribution form of the insulation module 200 and conductive module 100 in the power transmission unit. The conductive module 100 and insulation module 200 are arranged alternately in sequence. The form of the insulation module 200 is the same as that of the conductive module 100, which is also divided into multiple stacked insulators from top to bottom. The insulators and conductors correspond one-to-one. Along the flat direction, the insulators and conductors in the same layer form a flat layer, and the insulators and conductors in the flat layer are arranged alternately in sequence. The insulators can isolate and insulate adjacent conductors in the flat direction to ensure the power transmission independence of adjacent conductors. A total insulation layer (total insulation layer) is provided between adjacent flat layers. The insulating layer is located in the corresponding area of the conductor (i.e., serves as the sub-insulating layer 140 in the conductive module 100). During processing, it can be laid layer by layer in units of flat layers, i.e., one flat layer is laid, then one total insulating layer is laid, then another flat layer is laid, and so on, thereby completing the processing and assembly of the power transmission unit, which makes the processing more convenient. In addition, setting the sub-insulating layer 140 as a total insulating layer laid as a whole can effectively isolate adjacent conductors in the same conductive module 100, thereby improving the comprehensiveness of the isolation between conductors, ensuring independent power transmission between different conductors, and thus ensuring the normal operation of the conductive module 100.
[0035] Optionally, in this embodiment, a first outer insulating layer can be wrapped around the outside of the power transmission unit. The first outer insulating layer covers the entire power transmission unit and can isolate, insulate, and protect the entire power transmission unit, thereby reducing the occurrence of leakage current in the conductors located on the outside, and further ensuring the normal power transmission of the power transmission unit. In addition, as the outer shell of the power transmission unit, the first outer insulating layer can effectively reduce damage such as friction and collision caused by contact between the conductors and external components, and can also limit and fix the conductors and insulators covered therein, thereby improving the overall stability of the power transmission unit. Of course, in other embodiments, the outer insulation layer may only be laid above and below the power transmission unit. Specifically, when there are multiple power transmission units in the busbar 30, the first outer insulation layer can be wrapped around the outside of each power transmission unit as described above. Alternatively, multiple power transmission units can be stacked to form a whole, with adjacent power transmission units isolated and insulated by a flat insulation layer. Then, the first outer insulation layer is wrapped around the outside of the stacked power transmission units. Alternatively, a first outer insulation layer can be wrapped around the outside of a single power transmission unit first, and then another first outer insulation layer can be wrapped around the outside of the whole after multiple power transmission units are stacked to form a whole. In this case, the portion of the first outer insulation layer wrapped around the outside of the power transmission unit located between two adjacent power transmission units can serve as a flat insulation layer, eliminating the need for an additional flat insulation layer. Similarly, when the conductive module 100 forms a stacked unit in a stacked form, the outer insulation layer can also be wrapped around the outside of a single stacked unit or multiple stacked units forming a whole.
[0036] Specifically, in this embodiment, an outer shielding layer can be wrapped around the first outer insulation layer, and a second outer insulation layer can be wrapped around the outer shielding layer. When a single power transmission unit is wrapped around the first outer insulation layer, an outer shielding layer can be wrapped around the first outer insulation layer, and then a second outer insulation layer can be wrapped around the outer shielding layer. The outer shielding layer can shield the conductive module 100 in the power transmission unit from external equipment, thereby reducing electromagnetic interference generated by the conductive module 100 during power transmission to external equipment, and correspondingly reducing electromagnetic interference caused by equipment operation to the power transmission of the conductive module 100, thereby improving the stability of the power transmission of the conductive module 100 and the operational stability of the equipment. The second outer insulation layer can protect the outer shielding layer, thereby reducing wear on the outer shielding layer and reducing safety hazards caused by leakage of the outer shielding layer, thereby improving the safety of the busbar 30. When the busbar 30 includes multiple power transmission units, and each power transmission unit is covered with a first outer insulation layer, an outer shielding layer and a second outer insulation layer can be covered on the outside of the power transmission unit; when multiple power transmission units form a whole and are covered with a first outer insulation layer, an intermediate shielding layer can be set between adjacent power transmission units, and an outer shielding layer and a second outer insulation layer can be covered on the outside of the first outer insulation layer.
[0037] For details, please refer to Figure 3 The line bus 30 includes a power transmission unit, and multiple conductive modules and insulating modules within the power transmission unit are arranged in a flat configuration. Each conductive module 100 includes three conductors and two insulating layers 140. The three conductors are stacked from top to bottom as a first conductor 110, a second conductor 120, and a third conductor 130. An insulating layer 140 is provided between the first conductor 110 and the second conductor 120, and between the second conductor 120 and the third conductor 130. Along the flat direction, adjacent images... Each conductive module 100 is separated by a single insulating module 200. The top of the power transmission unit is covered with a first insulating layer 410 and the bottom is covered with a second insulating layer 420. Specifically, the first insulating layer 410 and the second insulating layer 420 can correspond to the shape and size of the top and bottom of the power transmission unit, respectively. The first insulating layer 410 and the second insulating layer 420 can also be two parts of insulating layer 140 corresponding to the top and bottom areas of the first outer insulating layer covering the entire outside of the power transmission unit (other areas of the first outer insulating layer are not shown in the figure).
[0038] Please refer to Figure 4 The line bus 30 includes a power transmission unit, and multiple conductive modules and insulating modules within the power transmission unit are arranged in a flat configuration, wherein the conductive module 100 and the insulating module 200 are connected to... Figure 3 The design is similar to the previous one, but the difference lies in that the top and bottom of this transmission unit are covered with two layers of insulation and one layer of shielding, arranged in a stacked manner. From top to bottom, these layers are: a first insulation layer 410, a first shielding layer 510, a second insulation layer 420, a third insulation layer 430, a second shielding layer 520, and a fourth insulation layer 440. The first insulation layer 410, the first shielding layer 510, and the second insulation layer 420 correspond to the top size and shape of the transmission unit, while the third insulation layer 430, the second shielding layer 520, and the fourth insulation layer 440 correspond to the bottom size and shape of the transmission unit. Corresponding to the size and shape of the components, the second insulating layer 420 and the third insulating layer 430 can also be two parts of insulating layer 140 corresponding to the top and bottom regions of the first outer insulating layer covering the entire outside of the power transmission unit. The first shielding layer 510 and the second shielding layer 520 can also be two parts of shielding layer corresponding to the top and bottom regions of the outer shielding layer covering the outside of the first outer insulating layer. The first insulating layer 410 and the fourth insulating layer 440 can also be two parts of insulating layer 140 corresponding to the top and bottom regions of the second outer insulating layer covering the outside of the outer shielding layer.
[0039] Please refer to Figure 5The line bus 30 includes a power transmission unit, and multiple conductive modules and insulating modules in the power transmission unit are arranged in a flat manner. The conductive module 100 includes three conductors, and the insulating module 200 includes three insulators. The three conductors of the same conductive module 100 are arranged in a stacked manner from top to bottom as the first conductor 110, the second conductor 120, and the third conductor 130. The three insulators of the same insulating module 200 are arranged in a stacked manner from top to bottom as the first insulator 210, the second insulator 220, and the third insulator 230. The insulators and conductors located in the same layer form a flat layer. Thus, the power transmission unit includes three flat layers, and a total insulating layer separates adjacent flat layers. The top and bottom of the transmission unit are covered with two layers of insulation and one layer of shielding, with two layers of insulation in the middle. From top to bottom, they are: first insulation layer 410, first shielding layer 510, second insulation layer 420, third insulation layer 430, fourth insulation layer 440, fifth insulation layer 450, second shielding layer 520, and sixth insulation layer 460. The third insulation layer 430 and fourth insulation layer 440 serve as the overall insulation layer between adjacent layers. The arrangement of the first insulation layer 410, first shielding layer 510, second insulation layer 420, fifth insulation layer 450, second shielding layer 520, and sixth insulation layer 460 is similar to... Figure 4 The first insulating layer 410, the first shielding layer 510, the second insulating layer 420, the third insulating layer 430, the second shielding layer 520, and the fourth insulating layer 440 correspond one-to-one, and their arrangement can be referred to Figure 4 The various insulating and shielding layers are not described in detail here.
[0040] Please refer to Figure 6The line bus 30 includes two identical power transmission units. Multiple conductive modules and insulating modules in each power transmission unit are arranged in a flat layout, and a flat shielding layer separates the two power transmission units. The conductive modules 100 and insulating modules 200 in each power transmission unit are arranged alternately along the flat layout direction. The conductive module 100 includes two conductors. The two conductors of the same conductive module 100 are stacked from top to bottom as the first conductor 110 and the second conductor 120. The two insulators of the same insulating module 200 are stacked from top to bottom as the first insulator 210 and the second insulator 220. The insulators and conductors in the same layer form a flat layer. Thus, the power transmission unit includes two flat layers, and a total insulating layer separates the adjacent flat layers. The top and bottom of the two transmission units in the line bar 30 are covered with two layers of insulation and one layer of shielding. An insulation layer separates the two flat layers of each transmission unit, and a flat insulation layer separates the two transmission units in the middle. From top to bottom, the layers are: first insulation layer 410, first shielding layer 510, second insulation layer 420, third insulation layer 430, fourth insulation layer 440, fifth insulation layer 450, sixth insulation layer 460, second shielding layer 520, and seventh insulation layer 470. The third insulation layer 430 serves as the overall insulation layer between the two flat layers in the upper transmission unit, the fourth insulation layer 440 serves as the flat insulation layer between the two transmission units, and the fifth insulation layer 450 serves as the overall insulation layer between the two flat layers in the lower transmission unit. The arrangement of the first insulation layer 410, first shielding layer 510, second insulation layer 420, sixth insulation layer 460, second shielding layer 520, and seventh insulation layer 470 is similar to... Figure 4 The first insulating layer 410, the first shielding layer 510, the second insulating layer 420, the third insulating layer 430, the second shielding layer 520, and the fourth insulating layer 440 correspond one-to-one, and their arrangement can be referred to Figure 4 The various insulating and shielding layers are not described in detail here. When the second insulating layer 420 and the sixth insulating layer 460 are two parts of the first outer insulating layer, the first outer insulating layer covers the outside of the two transmission units forming a whole.
[0041] Please continue to refer to this. Figure 7 The line bus 30 includes two stacked power transmission units, wherein the conductive module 100 and the insulating module 200 in the power transmission unit are in the same form as... Figure 6 The transmission units are all the same in form, the difference being that there are two layers of flat insulation between the two transmission units, and an intermediate shielding layer between the two layers of flat insulation; specifically, Figure 7The insulating and shielding layers are stacked from top to bottom as follows: first insulating layer 410, first shielding layer 510, second insulating layer 420, third insulating layer 430, fourth insulating layer 440, second shielding layer 520, fifth insulating layer 450, sixth insulating layer 460, seventh insulating layer 470, third shielding layer 530, and eighth insulating layer 480. The third insulating layer 430 serves as the total insulating layer between the two flat layers in the upper transmission unit, the second shielding layer 520 serves as the intermediate shielding layer between the two transmission units, and the sixth insulating layer 460 serves as the total insulating layer between the two flat layers in the lower transmission unit.
[0042] The first insulating layer 410, the first shielding layer 510, the second insulating layer 420, the fourth insulating layer 440, the second shielding layer 520, the fifth insulating layer 450, the seventh insulating layer 470, the third shielding layer 530, and the eighth insulating layer 480 can correspond to the shape and size of the corresponding position of the transmission unit, or they can be in the following form: the second insulating layer 420 and the fourth insulating layer 440 are two parts of insulating layer 140 covering the top and bottom regions of the first outer insulating layer outside the upper transmission unit; the fifth insulating layer 450 and the seventh insulating layer 470 are two parts of insulating layer 140 covering the top and bottom regions of the first outer insulating layer outside the lower transmission unit; the first shielding layer 510 and the second shielding layer 520 are two parts of insulating layer 140 covering the top and bottom regions of the first outer insulating layer outside the lower transmission unit; the first shielding layer 510 and the second shielding layer 520 are two parts of insulating layer 140 covering the top and bottom regions of the first outer insulating layer outside the lower transmission unit; the first shielding layer 510 and the second shielding layer 520 are two parts of insulating layer 140 covering the top and bottom regions of the first outer insulating layer outside the lower transmission unit. The first outer insulating layer of the shielding layer consists of two parts: a second shielding layer 520 and a third shielding layer 530, which are two parts of the outer shielding layer covering the first outer insulating layer below; and a first insulating layer 410 and an eighth insulating layer 480, which are two parts of the second outer insulating layer covering the entire outer surface of the two transmission units. Alternatively, the second insulating layer 420 and the seventh insulating layer 470 are two parts of the first outer insulating layer covering the entire outer surface of the two transmission units, with the first shielding layer 510 and the third shielding layer 530 being two parts of the outer shielding layer covering the first outer insulating layer, and the first insulating layer 410 and the eighth insulating layer 480 being two parts of the second outer insulating layer covering the outer shielding layer. Of course, the above are only examples of some specific forms, and the insulating and shielding layers can also be in other feasible forms.
[0043] It should be noted that the order of the insulating layer and shielding layer in the various figures of this application, such as First, Second, etc., is based on the viewpoint of the corresponding figure and is ordered from top to bottom. The ordering names of the insulating layer and shielding layer in different figures are relatively independent and unrelated. Furthermore, the directional terms such as "upper", "lower", "top", and "bottom" mentioned in the text are based on the viewpoint in the corresponding figure and are unrelated to the actual use of the cable strip 30, and are not used as a limitation on its usage direction.
[0044] Specifically, when the power supply type of power supply 10 is three-phase AC, the number of conductors in the conductive module 100 is three. The conductors in the same conductive module 100 are electrically connected to the three-phase lines of power supply 10 one-to-one through the input connector 20. In this case, it is possible to select... Figures 3-5 The cable tray 30 is shown; correspondingly, each group of connection terminals 50 has three connection terminals 50, and the three connection terminals 50 in the same group are electrically connected one-to-one with the three conductors of the corresponding conductive module 100 through the output connector 40; in use, the three connection terminals 50 are connected to the corresponding connection points of the drive motor 60. Optionally, the number of conductive modules 100 in the cable tray 30 can be set or selected according to the number of drive motors 60, such as... Figure 1 and Figure 2 As shown, there are four drive motors 60, four output connectors 40 in the busbar 30, and three connection terminals 50 connected to each output connector 40.
[0045] Specifically, the input connector 20 can be a single unit or, similar to the output connector 40, multiple separate units. When the input connector 20 is in a separate unit form, it can include a housing, terminals, and a waterproof gasket, forming a socket and a plug. The input socket contains pins equal in number to the conductors in the conductive module 100. In use, the socket is plugged into the output terminal of the conductive module 100, and its pins are electrically connected to the conductors of the conductive module 100 one-to-one. The plug can be connected to the power supply 10 via wires, etc. When the housings of the separate input connector 20 are integrated, the aforementioned integrated input connector 20 is formed. Specifically, the output connector 40 can include a housing, terminals, and insulating potting compound. The conductors are connected to the connecting terminals 50 via terminals and conductive connections. The insulating potting compound fills the gap between the housing and the terminals, providing fixation and waterproofing. Preferably, the housings of the input connector 20 and the output connector 40 can be made of heat-resistant and high-temperature-resistant non-metallic insulating materials such as plastic.
[0046] Preferably, in this embodiment, the output end of each conductive module 100 can form a protruding connection position 300. Multiple connection positions 300 are distributed circumferentially along the line array 30, and the output connector 40 is electrically connected to the output end of the corresponding conductive module 100 at the connection position 300. The protruding connection position 300 facilitates the connection and assembly of the output connector 40 and the output end of the conductive module 100, thereby improving the assembly convenience of the power line device and ensuring the firmness of the electrical connection between the output connector 40 and the conductive module 100. Furthermore, the multiple connection positions 300 are distributed axially along the line array 30. Specifically, the position and protruding direction of each connection position 300 can be determined according to the distribution orientation of the drive motors 60 to be connected, thereby improving the connection convenience between the connection terminal 50 and the corresponding drive motor 60. When the connection terminal 50 and the output connector 40 are connected by a wire, the occurrence of wire entanglement can be effectively reduced.
[0047] When the power supply type of power supply 10 is AC, the number of conductors in the conductive module 100 is two. The conductors in the same conductive module 100 are electrically connected to the power line and ground line of power supply 10 one by one through the input connector 20. At this time, it is possible to select Figure 6 and Figure 7 The wire bar 30 is shown; correspondingly, there are two connection terminals 50 in each group of connection terminals 50, and the two connection terminals 50 in the same group are electrically connected to the two conductors of the corresponding conductive module 100 one by one through the output connector 40; in use, the two connection terminals 50 are connected to the corresponding connection points of the drive motor 60.
[0048] Of course, in other embodiments, the number of conductors in the conductive module 100 can be set to four, five, etc., depending on the power supply type of the power supply 10; and in the same power transmission unit, the number of conductors in different conductive modules 100 can be the same or different, and the current-carrying cross section of the conductors in different conductive modules 100 can also be set differently according to the actual power transmission capacity; the forms of different power transmission units of the same busbar 30 can be the same or different.
[0049] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
