[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0053] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0055] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0056] Reference Figures 1 to 12 As shown, this embodiment provides an inverter, which includes a first housing 100, a first connector 200, a first pair of plugs 300, a second housing 400, a second connector 500, and a second pair of plugs 600. The first connector 200 and the first pair of plugs 300 are disposed on the first housing 100, and the second connector 500 and the second pair of plugs 600 are disposed on the second housing 400.

[0057] The first pair of plugs 300 is provided with a first guide post 301, and the second pair of plugs 600 is provided with a first guide channel 601; the first connector 200 is provided with a first terminal 210, the second connector 500 is provided with a second terminal 510, and one of the first connector 200 and the second connector 500 is provided with a second guide post 220, and the other is provided with a second guide channel 520.

[0058] In this embodiment, the length of the second guide post 220 is less than the length of the first guide post 301. It is understood that the first guide post 301, inserted into the first guide channel 601 along a first direction, guides the insertion between the second guide post 220 and the second guide channel 520; the second guide post 220, inserted into the second guide channel 520, guides the insertion between the first terminal 210 and the second terminal 510. The second guide post 220 can be inserted into the second guide channel 520 along a first direction. This first direction can be the length direction of the inverter.

[0059] It is understandable that when a component in the first enclosure 100 is damaged, only the first enclosure 100 needs to be replaced; when a component in the second enclosure 400 is damaged, only the first enclosure 100 needs to be replaced. That is, if a component in either the first enclosure 100 or the second enclosure 400 is damaged, the other does not need to be replaced, which helps to save resources and reduce costs.

[0060] During assembly, firstly, the first guide post 301 is inserted into the first guide channel 601 along a first direction. The cooperation between the first guide post 301 and the first guide channel 601 guides the second guide post 220 to be inserted into the second guide channel 520, thus initially positioning the first connector 200 and the second connector 500. Then, the second guide post 220 is inserted into the second guide channel 520 to precisely position the connection between the first terminal 210 and the second terminal 510, which helps improve the positioning and connection efficiency between the first connector 200 and the second connector 500. It can be understood that the first guide post 301 of the first pair of plugs 300 is inserted into the first guide channel 601 of the corresponding second pair of plugs 600 along a first direction, the second guide post 220 is then inserted into the second guide channel 520, and finally the first terminal 210 and the second terminal 510 are connected together.

[0061] For example, one of the first enclosure 100 and the second enclosure 400 is a main enclosure, and the other is a wiring expansion enclosure. The main enclosure can be used to house the inverter main unit, and the wiring expansion enclosure is used to house the bus protection components.

[0062] For example, the first housing 100 and the second housing 400 can be formed by welding sheet metal.

[0063] In one feasible implementation, the first guide post 301 is inserted into the first guide channel 601 along the first direction, which can guide the insertion between the first terminal 210 and the second terminal 510, thereby reducing the risk of the second guide post 220 breaking.

[0064] In some embodiments, to prevent the positional accuracy between the first pair of plugs 300 and the first connector 200, and between the second pair of plugs 600 and the second connector 500, from affecting the assembly of the inverters, the first guide post 301 and the first guide channel 601 are clearance-fitted, and the second guide post 220 and the second guide channel 520 are clearance-fitted. The gap between the first guide post 301 and the first guide channel 601 is greater than or equal to the gap between the second guide post 220 and the second guide channel 520, which facilitates the insertion of the first terminal block 210 and the second terminal block 510.

[0065] In other embodiments, the first guide post 301 and the first guide channel 601 can be frustoconical in shape. For example, when the first pair of plugs 300 and the second pair of plugs 600 are fastened together by the locking fastener 730, the periphery of the first guide post 301 fits against the inner surface of the first guide channel 601, which helps to improve the connection strength and reduces the risk of breakage of the second guide post 220.

[0066] In one feasible implementation, such as Figure 6and Figure 9 As shown, the first guide post 301 has a guide rib 302 around its periphery, and the second pair of plug-in 600 has a guide groove 602 communicating with the first guide channel 601. The guide rib 302 is inserted into the guide groove 602. In this embodiment, the guide rib 302 helps to strengthen the structural strength of the first guide post 301, and the cooperation between the guide rib 302 and the guide groove 602 further facilitates the positioning and insertion between the first connector 200 and the second connector 500.

[0067] For example, two to four guide ribs 302 are provided at circumferential intervals along the first guide post 301.

[0068] For example, the first pair of plug-in modules 300 is provided with at least one first guide post 301. For instance, the first pair of plug-in modules 300 is provided with two or three first guide posts 301 arranged side by side along a second direction or a third direction, and the first guide posts 301 and the first guide channels 601 are configured in a one-to-one correspondence. For example, the first direction, the second direction, and the third direction are perpendicular to each other. The second direction can be the height direction of the inverter, and the third direction can be the thickness direction of the inverter.

[0069] For example, the end of the first guide post 301 may be provided with a chamfer or a rounded corner.

[0070] For example, the end of the second guide post 220 may be provided with a chamfer or a rounded corner.

[0071] In this embodiment, reference is made to Figures 1 to 3 , Figures 5 to 7 As shown, the first housing 100 includes a first connecting plate 110 and a first fixing plate 120 arranged at an angle. The first connector 200 is disposed on the first connecting plate 110. The first pair of plugs 300 includes a first support surface 311 and a second support surface 321 arranged at an angle. The first support surface 311 abuts against the first connecting plate 110, and the second support surface 321 abuts against the first fixing plate 120, which facilitates the positioning and assembly of the first pair of plugs 300 on a corner of the first housing 100 formed by the first connecting plate 110 and the first fixing plate 120.

[0072] For example, the first connecting plate 110 and the first fixing plate 120 may be flat.

[0073] For example, the first connecting plate 110 and the first fixing plate 120 are perpendicular to each other, that is, the first supporting surface 311 and the second supporting surface 321 are perpendicular to each other. The first box 100 can be a rectangular box.

[0074] In one feasible implementation, the first pair of plug-in 300 is provided with a first clearance groove 303 between the first support surface 311 and the second support surface 321. In this embodiment, the first housing 100 is formed by sheet metal welding, and the flatness tolerance of the first connecting plate 110 and the first fixing plate 120 is relatively large. The first clearance groove 303 can form a favorable clearance, which is conducive to the first support surface 311 abutting against the first connecting plate 110 and the second support surface 321 abutting against the first fixing plate 120.

[0075] For example, the first clearance slot 303 extends through the first pair of plugs 300 on both sides along the third direction, which can form a more advantageous clearance.

[0076] In one feasible implementation, the first pair of plug-ins 300 includes a first support portion 310 and a second support portion 320 arranged at an angle. The first support portion 310 is provided with a first guide post 301 and a first support surface 311, and the second support portion 320 is provided with a second support surface 321, which helps to improve the structural compactness of the first pair of plug-ins 300. In some embodiments, the first pair of plug-ins 300 is right-angled.

[0077] For example, a portion of the first clearance groove 303 is located on the first support portion 310, and another portion is located on the second support portion 320.

[0078] In one feasible implementation, the first connecting plate 110 is provided with a first positioning post, and the first supporting surface 311 is provided with a first positioning hole 314. The first positioning post is inserted into the first positioning hole 314 along the first direction, which cooperates with the first supporting surface 311 of the first pair of plug-in 300 to abut against the first connecting plate 110, and the second supporting surface 321 of the first pair of plug-in 300 to abut against the first fixing plate 120, which is more conducive to the positioning and assembly of the first pair of plug-in 300 on the first housing 100.

[0079] For example, the first support portion 310 is provided with at least one first positioning hole 314, and the first positioning post corresponds one-to-one with the first positioning hole 314.

[0080] In one feasible implementation, the inverter further includes a first fastener (not shown) and a second fastener 710. The first support 310 is fastened to the first connecting plate 110 by the first fastener, and the second support 320 is fastened to the first fixing plate 120 by the second fastener 710, so as to facilitate the assembly of the first pair of plug-ins 300 onto the first housing 100. In this embodiment, the first housing 100 is formed by sheet metal welding. The positional accuracy of the first connecting plate 110 and the first fixing plate 120 is relatively low. The structural strength of the first pair of plug-ins 300 is greater than that of the first housing 100. The pulling of the first fastener on the first connecting plate 110 and the pulling of the second fastener 710 on the first fixing plate 120 can make the first support surface 311 tightly abut against the first connecting plate 110 and the second support surface 321 tightly abut against the first fixing plate 120. This is beneficial to improving the structural strength of the first housing 100 and has the function of correcting the first housing 100. This is beneficial to improving the positional accuracy between the first connecting plate 110 and the first fixing plate 120, for example, it is beneficial to improve the vertical accuracy between the first connecting plate 110 and the first fixing plate 120. This is beneficial to improving the positional accuracy of the first pair of plug-ins 300 relative to the first housing 100. This is beneficial to positioning and inserting the first guide post 301 of the first pair of plug-ins 300 into the first guide channel 601 of the corresponding second pair of plug-ins 600 along the first direction. This is beneficial to positioning and inserting the first connector 200 and the second connector 500.

[0081] For example, the first fastener may be a bolt.

[0082] For example, the hole on the first support portion 310 for the first fastener to pass through can be a countersunk hole.

[0083] For example, the first fastener passes through the first support portion 310 and the first connecting plate 110 and is threadedly connected to the nut, or the first fastener passes through the first support portion 310 and is threadedly connected to the first connecting plate 110.

[0084] For example, the first pair of plugs 300 corresponds to at least one first fastener, such as one first pair of plugs 300 corresponding to two or three first fasteners side by side along a third direction.

[0085] For example, the second fastener 710 may be a bolt.

[0086] For example, the hole on the second support 320 through which the second fastener 710 passes can be a countersunk hole.

[0087] For example, the second fastener 710 passes through the second support portion 320 and the first fixing plate 120 and is threadedly connected to the nut, or the second fastener 710 passes through the second support portion 320 and is threadedly connected to the first fixing plate 120.

[0088] For example, the first pair of plugs 300 corresponds to at least one second fastener 710, such as one first pair of plugs 300 corresponding to two or three second fasteners 710 side by side along a third direction.

[0089] In this embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 , Figures 8 to 10 As shown, the second housing 400 includes a second connecting plate 410 and a second fixing plate 420 arranged at an angle. The second connector 500 is disposed on the second connecting plate 410. The second pair of plugs 600 includes a third support surface 611 and a fourth support surface 621 arranged at an angle. The third support surface 611 abuts against the second connecting plate 410, and the fourth support surface 621 abuts against the second fixing plate 420, which facilitates the positioning and assembly of the second pair of plugs 600 on a corner of the second housing 400 formed by the second connecting plate 410 and the second fixing plate 420.

[0090] For example, the second connecting plate 410 and the second fixing plate 420 may be flat.

[0091] For example, the second connecting plate 410 and the second fixing plate 420 are perpendicular to each other, that is, the third supporting surface 611 and the fourth supporting surface 621 are perpendicular to each other. The second box 400 can be a rectangular box.

[0092] In one feasible implementation, the second pair of inserts 600 is provided with a second clearance groove 603 between the third support surface 611 and the fourth support surface 621. In this embodiment, the second housing 400 is formed by sheet metal welding, and the flatness tolerance of the second connecting plate 410 and the second fixing plate 420 is relatively large. The second clearance groove 603 can form a favorable clearance, which is beneficial for the third support surface 611 to abut against the second connecting plate 410 and for the fourth support surface 621 to abut against the second fixing plate 420.

[0093] For example, the second clearance slot 603 extends through the second pair of plugs 600 on both sides along the third direction, which can form a more advantageous clearance.

[0094] In one feasible implementation, the second pair of plugs 600 includes a third support portion 610 and a fourth support portion 620 arranged at an angle. The third support portion 610 is provided with a first guide channel 601 and a third support surface 611, and the fourth support portion 620 is provided with a fourth support surface 621, which helps to improve the structural compactness of the second pair of plugs 600. In some embodiments, the second pair of plugs 600 is right-angled.

[0095] For example, a portion of the second clearance groove 603 is located on the third support 610, and another portion is located on the fourth support 620.

[0096] In one feasible implementation, the second connecting plate 410 is provided with a second positioning post, and the third supporting surface 611 is provided with a second positioning hole 614. The second positioning post is inserted into the second positioning hole 614 along the first direction, which cooperates with the third supporting surface 611 of the second pair of plug-in 600 to abut against the second connecting plate 410, and the fourth supporting surface 621 of the second pair of plug-in 600 to abut against the second fixing plate 420, which is more conducive to the positioning and assembly of the second pair of plug-in 600 on the second housing 400.

[0097] For example, the third support portion 610 is provided with at least one second positioning hole 614, and the second positioning post corresponds one-to-one with the second positioning hole 614.

[0098] In one feasible implementation, the inverter further includes a third fastener (not shown) and a fourth fastener 720. The third support 610 is fastened to the second connecting plate 410 by the third fastener, and the fourth support 620 is fastened to the second fixing plate 420 by the fourth fastener 720, so as to facilitate the assembly of the second pair of plug-in 600 onto the second housing 400. In this embodiment, the second housing 400 is formed by sheet metal welding. The positional accuracy of the second connecting plate 410 and the second fixing plate 420 is relatively low. The structural strength of the second pair of plug-ins 600 is greater than that of the second housing 400. The pulling of the third fastener on the second connecting plate 410 and the pulling of the fourth fastener 720 on the second fixing plate 420 can make the third support surface 611 tightly abut against the second connecting plate 410 and the fourth support surface 621 tightly abut against the second fixing plate 420.
