[0047] In the related art, the cables of internal components of the power conversion device can be electrically connected with the conductive bars, and the wiring terminals of the external cables and the conductive bars are fixed by the mounting members on the terminal table to realize the wiring assembly of the internal components of the power conversion device and the external cables. However, the docking operation of the terminal table and the wiring terminal is mostly cumbersome, and the installation wiring is difficult, which reduces the wiring convenience and assembly efficiency of the power conversion device. In view of the above problems, the present application provides a power conversion device 100.

[0048] Please refer to Figures 1 to 19In an embodiment of the present application, the power conversion device 100 comprises a casing, a terminal block 10 and a conductive strip 30, the terminal block 10 is connected to the casing 50, the terminal block 10 is provided with a terminal seat 11, the terminal seat 11 is provided with a mounting member 13, the mounting member 13 is connected and fixed to the terminal 21, the conductive strip 30 is connected to the terminal block 10 and at least partially arranged on the surface of the terminal seat 11, and the conductive strip 30 is electrically connected to the terminal 21. Wherein, the mounting member 13 is movably arranged relative to the terminal seat 11, and / or the terminal seat 11 is movably arranged relative to the terminal block 10.

[0049] It can be understood that the power conversion device 100 can be an inverter, a converter or other power electronic device / energy conversion device, by arranging the terminal block 10 in the casing 50 of the power conversion device 100, a plurality of cables of internal components of the power conversion device 100 can be connected to a plurality of independent conductive strips 30, so that the external cable 200 can be connected to the corresponding conductive strip 30 on the terminal seat 11 of the terminal block 10 to be electrically connected to the internal components of the power conversion device 100, to ensure the stable connection of the power conversion device 100 and the external cable 200, and to realize the stable and reliable operation of the power conversion device 100. It should be noted that when the casing 50 comprises a first casing 51 and a second casing 53, the power elements, control elements and other devices of the power conversion device 100 can be arranged in the first casing 51, and the terminal block 10 and the conductive strip 30 can be arranged in the second casing 53, to realize better overall layout and convenient power connection of the power conversion device 100. The power connection components on the terminal block 10 can be connected to the devices in the first casing 51 by penetrating the second casing 53 and the first casing 51, or the terminal block 10 can be electrically connected to the devices in the first casing 51 by penetrating the first casing 51 and the second casing 53, to ensure the stable operation of the power conversion device 100.

[0050] Wherein, the external cable 200 can be crimped with an OT terminal or other terminal 21 at the end of the wire, and the mounting member 13 such as a bolt, a pressing block, a latch or a clamping buckle can be arranged on the terminal seat 11 of the terminal block 10 to connect and fix the terminal 21 of the external cable 200, so that the terminal 21 can stably contact the conductive strip 30 under the fastening action of the mounting member 13, to realize the stable electrical connection between the external cable 200 and the conductive strip 30, and to ensure the stable and reliable connection between the terminal block 10 and the external cable 200.

[0051] In some embodiments of the present application, the terminal table 10 can movably arrange the mounting member 13 on the terminal seat 11, and can make the mounting member 13 move horizontally, rotate, or the like within a certain range on the surface of the terminal seat 11, or can make the mounting member 13 swing at a certain angle relative to the surface of the terminal seat 11. Thus, when the terminal end 21 of the external cable 200 is connected with the mounting member 13, the position of the mounting member 13 on the terminal seat 11 can be adjusted by the movement of the mounting member 13, so that the mounting member 13 can be stably connected with the terminal end 21. This is beneficial for the assembly of the terminal table 10 and the multi-core wire, and the mounting member 13 can be adjusted according to the position of the terminal end 21 of the multi-core wire, so that the terminal table 10 can better adapt to the assembly of the multi-core wire with installation deviation. In this way, the installation worker does not need to bend or pull the multi-core wire of the external cable 200 to make the terminal ends 21 keep in a straight line for installation, which effectively reduces the connection operation difficulty of the terminal table 10 and improves the assembly connection convenience and practicality of the power conversion device 100.

[0052] In some embodiments of the present application, the terminal table 10 can movably arrange the mounting member 13 on the terminal seat 11, and can make the mounting member 13 move horizontally, rotate, or the like within a certain range on the surface of the terminal seat 11, or can make the mounting member 13 swing at a certain angle relative to the surface of the terminal seat 11. Thus, when the terminal end 21 of the external cable 200 is connected with the mounting member 13, the position of the mounting member 13 on the terminal seat 11 can be adjusted by the movement of the mounting member 13, so that the mounting member 13 can be stably connected with the terminal end 21. This is beneficial for the assembly of the terminal table 10 and the multi-core wire, and the mounting member 13 can be adjusted according to the position of the terminal end 21 of the multi-core wire, so that the terminal table 10 can better adapt to the assembly of the multi-core wire with installation deviation. In this way, the installation worker does not need to bend or pull the multi-core wire of the external cable 200 to make the terminal ends 21 keep in a straight line for installation, which effectively reduces the connection operation difficulty of the terminal table 10 and improves the assembly connection convenience and practicality of the power conversion device 100.

[0053] In some embodiments of the present application, the terminal table 10 can movably arrange the mounting member 13 on the terminal seat 11, and can make the mounting member 13 move horizontally, rotate, or the like within a certain range on the surface of the terminal seat 11, or can make the mounting member 13 swing at a certain angle relative to the surface of the terminal seat 11. Thus, when the terminal end 21 of the external cable 200 is connected with the mounting member 13, the position of the mounting member 13 on the terminal seat 11 can be adjusted by the movement of the mounting member 13, so that the mounting member 13 can be stably connected with the terminal end 21. This is beneficial for the assembly of the terminal table 10 and the multi-core wire, and the mounting member 13 can be adjusted according to the position of the terminal end 21 of the multi-core wire, so that the terminal table 10 can better adapt to the assembly of the multi-core wire with installation deviation. In this way, the installation worker does not need to bend or pull the multi-core wire of the external cable 200 to make the terminal ends 21 keep in a straight line for installation, which effectively reduces the connection operation difficulty of the terminal table 10 and improves the assembly connection convenience and practicality of the power conversion device 100.

[0054] Therefore, compared with the terminal table 10 fixedly arranged by the mounting structure, by movably arranging the mounting member 13 on the terminal seat 11 and / or movably arranging the terminal seat 11 on the terminal table 10, the movement, rotation or swing of the terminal seat 11 can be adjusted, so that when the terminal table 10 is assembled with the multi-core wire, after some of the terminal ends 21 are connected with some of the mounting members 13, the positions of the mounting members 13 can be adjusted according to the position deviation of the remaining terminal ends 21 to be connected with the remaining mounting members 13 one by one, which is beneficial to reduce the wiring operation difficulty of the terminal table 10 and improve the wiring convenience and assembly efficiency of the power conversion device 100.

[0055] Referring to Figure 10 , Figure 11 , Figure 12 and Figure 16 , in an embodiment of the present application, the terminal seat 11 is provided with a first accommodating groove 115, and the mounting member 13 comprises a movable part 131a and a mounting part 133a, wherein the movable part 131a is movably arranged in the first accommodating groove 115, and the mounting part 133a is connected with the movable part 131a.

[0056] In the embodiment, the mounting member 13 can comprise the movable part 131a and the mounting part 133a, and at this time, the mounting member 13 can arrange the movable part 131a in the first accommodating groove 115 of the terminal seat 11, and at least part of the mounting part 133a is arranged to protrude from the first accommodating groove 115 to be connected with the terminal end 21, so that by moving or rotating the movable part 131a in the first accommodating groove 115, the mounting part 133a can be moved or rotated correspondingly, so that the terminal table 10 can stably adjust the position of the mounting member 13 to be connected with the terminal end 21, and further improve the structural stability and reliability of the terminal table 10.

[0057] As shown in some embodiments of Figures 10 to 13 , the terminal seat 11 can be arranged such that the size of the groove body of the first accommodating groove 115 is greater than the size of the movable part 131a, and the movable part 131a is limited by the cover plate 113 above the first accommodating groove 115 or by the conductive row 30, so as to prevent the movable part 131a from being separated from the first accommodating groove 115, so that the movable part 131a can stably move in the first accommodating groove 115 to adjust the position of the mounting member 13; or as shown in some embodiments of Figure 10As can be seen in some of the embodiments shown, the first receiving groove 115 can be configured to enclose the movable part 131a, so that the movable part 131a can be limited to rotate within the receiving groove 115 to achieve adjustment of the installation member 13. Therefore, this application does not limit the movement mode of the movable part 131a within the first receiving groove 115, as long as the movable part 133a can move within the first receiving groove 115.

[0058] Furthermore, in one embodiment of this application, the movable part 131a and the mounting part 133a are an integral structure, and the mounting component 13 further includes a fastener 135, which connects to the mounting part 133a and fixes the terminal 21. Alternatively, the movable part 131a and the mounting part 133a can be detachably connected, and the mounting part 133a fixes the terminal 21.

[0059] It is understandable that, such as Figure 10 , Figure 12 , Figure 13 As shown in some embodiments, the movable part 131a and the mounting part 133a of the mounting member 13 can be an integral structure. This integral structure can take various forms, including but not limited to: the movable part 131a and the mounting part 133a being an integral bolt nut and shank; or, the movable part 131a and the mounting part 133a being an integral pin with a "T"-shaped structure. In this case, the mounting member 13 can be connected to the mounting part 133a using a fastener 135, which presses against the terminal 21 fitted on the mounting part 13, ensuring stable contact and conduction between the terminal 21 and the conductive busbar 30. Furthermore, the movable part 131a can move or rotate within the receiving groove 115, allowing the mounting part 133a to move with the movable part 131a to the corresponding position of the terminal 21 for installation. The fastener 135 can have various structures. For example, the fastener 135 can be a nut that is threadedly installed with the mounting part 133a, or the fastener 135 can be a sleeve that is fitted and fixed on the mounting part 133a. As long as the fastener 135 can be connected with the mounting part 133a and press the terminal 21, there is no limitation here.

[0060] By adopting an integrated structure for the mounting component 13, the overall structural strength of the mounting component 13 can be improved. At the same time, the mounting part 133a of the mounting component 13 can be made to protrude above the terminal block 11. This facilitates the pre-installation of the terminal block 21 onto the mounting part 133a during wiring assembly. Then, the fasteners such as nuts or fixing sleeves of the mounting component 13 are connected and fixed to the mounting part 133a, further improving the wiring convenience and practicality of the terminal block 10.

[0061] Furthermore, in other embodiments, such asFigure 11 As shown in some embodiments of the present application, the movable part 131a and the mounting part 133a of the mounting member 13 can be provided in a detachable split structure. The split structure can be in various forms, including but not limited to: the movable part 131a and the mounting part 133a can be a nut and a bolt, respectively, or the movable part 131a and the mounting part 133a can be a fixed sleeve and a pin, respectively. Exemplarily, in some embodiments, the movable part 131a can be provided with a mounting hole corresponding to the mounting part 133a for plug-in connection, so that the terminal base 10 can movably accommodate the nut or the fixed sleeve as the movable part 131a in the first accommodating groove 115, and expose the mounting hole of the movable part 131a on the surface of the terminal seat 11, so that the position of the movable part 131a can be adjusted by moving or rotating according to the position of the terminal 21, and then the mounting part 133a is inserted and fixed into the mounting hole of the movable part 131a through the terminal 21, so as to stably mount the terminal 21 on the terminal seat 11 by the mounting member 13. The end of the mounting part 133a opposite to the movable part 131a can be provided with a nut for pressing the terminal 21, or a pin can be provided on the mounting part 133a for pressing the terminal 21. The present application does not limit the pressing structure of the mounting part 133a and the terminal 21, as long as the mounting part 133a can stably press the terminal 21 on the conductive strip 30.

[0062] By providing the detachable split connection structure of the movable part 131a and the mounting part 133a, the mounting part 133a can be connected to the terminal 21 first, and then the terminal 21 is placed on the terminal seat 11, and the terminal 21 is pressed and fixed on the conductive strip 30 by the connection of the mounting part 133a and the movable part 131a, so as to stably connect the terminal 21 and the conductive strip 30, and further improve the convenience and practicability of the terminal base 10.

[0063] Referring to Figures 10 to 13 In an embodiment of the present application, the volume of the first accommodating groove 115 is greater than the volume of the movable part 131a.

[0064] In the present embodiment, the terminal seat 11 can be provided with a first accommodating groove 115 with an area greater than the area of the movable part 131a of the mounting member 13, or a groove depth greater than or equal to the thickness of the movable part 131a, so that the overall volume of the first accommodating groove 115 is greater than the volume of the movable part 131a, and the first accommodating groove 115 can have a certain space for the movable part 131a to move or rotate, so as to adjust the position of the mounting member 13, and stably connect and mount the terminal 21 of the external cable 200 and the mounting member 13.

[0065] In some embodiments, the terminal block 11 can limit the movable part 131a by using the inner wall of the first receiving groove 115. For example, the first receiving groove 115 can be set as a long strip or a cross-shaped structure so that the movable part 131a can slide horizontally under the limiting action of the first receiving groove 115, thereby adjusting the position of the mounting part 13. Alternatively, a moving structure can be provided between the inner wall of the first receiving groove 115 and the movable part 131a to realize the directional movement or rotation of the movable part 131a within the first receiving groove 115. In this case, the moving structure can be a slider rail structure so that the movable part 131a can slide stably under the limiting and guiding action of the moving structure. Alternatively, the moving structure can be a rotating shaft protruding from the bottom wall of the first receiving groove 115 so that the movable part 131a of the mounting part 13, which adopts an eccentric wheel or cam structure, can be connected to the moving structure, thereby allowing the mounting part 133a to rotate eccentrically under the drive of the movable part 131a, thereby adjusting the position of the mounting part 13.

[0066] In addition, such as Figure 12 As can be seen in some embodiments shown, when the area inside the first receiving groove 115 is larger than the area of ​​the movable part 131a, and the depth of the first receiving groove 115 is also greater than the thickness of the movable part 131a, the movable part 131a can also perform a certain angle range of flipping action within the first receiving groove 115. That is, the movable part 131a can swing in a third direction within the first receiving groove 115. At this time, the movable part 131a can drive the mounting part 133a to tilt and swing relative to the surface of the terminal block 11, or the mounting part 133a can be tilted at a certain angle and inserted into the mounting hole of the movable part 131a. This allows the mounting part 13 to tilt and swing at a certain angle on the terminal block 11 and mate with the terminal 21, ensuring the stable position adjustment of the mounting part 13 and further improving the practicality and reliability of the terminal block 10. For ease of understanding and explanation, all references to the first part are used. Figure 18 and Figure 19 The coordinate system shown in the figure indicates the directions as references, where the first direction is the positive direction of the x-axis, the second direction is the positive direction of the y-axis, and the third direction is the positive direction of the z-axis.

[0067] In other embodiments, the terminal seat 11 can be provided with a cover plate 113 covering the first accommodating groove 115 above the groove opening, and the mounting portion 133a can be provided with an opening for the mounting portion 133a to pass through, so that the plate structure can block the movable portion 131a from being pulled out of the groove opening of the first accommodating groove 115, ensuring the stable arrangement of the mounting member 13 in the terminal seat 11. Alternatively, the conductive strip 30 can be arranged to cover the first accommodating groove 115 above the groove opening, and the mounting portion 133a can be provided with an opening for the mounting portion 133a to pass through, so that the conductive strip 30 can block the movable portion 131a from being pulled out of the groove opening of the first accommodating groove 115, ensuring the stable arrangement of the mounting member 13 in the terminal seat 11, and further improving the overall structural stability and reliability of the terminal block 10.

Of course, this application is not limited to these connection methods for the first housing 51 and the second housing 53. The first housing 51 and the second housing 53 can also adopt other connection methods, which are not limited in this application.

[0104] The terminal block 10 can be slidably connected to the second housing 53, or it can be rotatably connected to the second housing 53, or it can be oscillatingly connected to the second housing 53 through an elastic or flexible structure, thereby realizing the movable setting of the terminal block 10 within the second housing 53.

By providing a sliding groove 115 on the bottom wall of the terminal block 10, and utilizing the cooperation between the raised slide rail 533 and the sliding groove 115, the terminal block 10 can slide along the extending direction of the raised slide rail 533 within the second housing 53, thereby realizing the position adjustment of the terminal block 10 within the second housing 53. Of course, the terminal block 10 and the second housing 53 can also adopt other connection structures, as long as they enable the terminal block 10 to move relative to the second housing 53 within the second housing 53; this application does not limit this. Furthermore, when multiple external cables of different lengths need to be installed on the terminal block 10 or multi-core wires need to be connected, the overall position of the terminal block 10 can be adjusted by moving it so that the position of the mounting part 13 of the terminal block 10 can be adjusted according to the position of multiple terminals 21, so that the mounting part 13 can be more stably mated and fixed with multiple terminals 21, further improving the convenience of wiring operation of the terminal block 10.
