[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0045] In the description of the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0046] Currently, EMC anti-interference measures in the inverter field typically include adding Y capacitors to circuit components to suppress interference, using conductive sealing strips, adding shielding covers to magnetic components such as inductors, and applying magnetic rings to cables. Attaching magnetic rings to cables typically requires heat shrink tubing to secure the rings to the cables. This results in a complex process, inconvenient assembly, and difficulty quantifying the positioning of the heat shrink tubing and magnetic rings, impacting production efficiency and quality.

[0047] To this end, the present application provides an interface component and a photovoltaic inverter, which have the technical effects of simplifying the assembly process, facilitating assembly, and improving production efficiency.

[0048] like Figure 1 and Figure 2 As shown, the present application first provides an interface assembly 100, which can be applied to a photovoltaic inverter 1000. The photovoltaic inverter 1000 includes a housing 500, an interface assembly 100, and a circuit assembly 600. The interface assembly 100 includes a connector 200, a magnetic ring 300, and a cable 400. Among them, the circuit assembly 600 is disposed in the housing 500, the connector 200 is embedded and fixed in the housing 500, and the magnetic ring 300 is fixed to the connector 200. The cable 400 includes a cable conductor 401 and a cable sheath 402 that wraps the cable conductor 401. The cable 400 is inserted through the connector 200, the magnetic ring 300, and the housing 500. One end of the cable 400 is connected to the circuit assembly 600, and the other end of the cable 400 is provided with a connector 403. The cable 400 is connected to a device outside the photovoltaic inverter 1000, and the magnetic ring 300 is sleeved on the magnetic ring 300 to achieve EMC anti-interference function.

[0049] like Figure 2 and Figure 3 As shown, in this embodiment, the connector 200 includes a base 10 and a latch 20. The base 10 is used to be fixed to the housing 500. The base 10 is provided with a threading hole 11 that passes through the base 10 and is used to pass the cable 400. The base 10 has an assembly area 12 on one side for mounting the magnetic ring 300.

[0050] The fasteners 20 are connected to the base 10 and are distributed around the assembly area 12. A magnetic ring 300 is positioned in the assembly area 12 and is secured between the fasteners 20. The magnetic ring 300 is provided with a connecting hole 301 that communicates with the wire threading hole 11. The cable 400 is passed through the wire threading hole 11 and the connecting hole 301, respectively. It will be understood that the base 10 secures the magnetic ring 300 to the assembly area 12 via the fasteners 20, so that the magnetic ring 300 is securely mounted on the cable 400.

[0051] For example, the base 10 is generally elongated, with a threading hole 11 extending through both sides of the base 10 along its thickness (i.e., the Z-axis direction in the figure). An assembly area 12 is formed on one side of the base 10 and is the space occupied by the magnetic ring 300 when mounted on the base 10. The inner diameter of the threading hole 11 can be configured based on the diameter of the cable 400.

[0052] The magnetic ring 300 is generally elongated and shorter than the base 10. A communication hole 301 extends through both sides of the magnetic ring 300 along its thickness. The inner diameter and position of the communication hole 301 correspond to those of the threading hole 11. For ease of description, the surfaces at both ends of the magnetic ring 300 in the thickness direction are defined as end faces, and the axial surfaces of the magnetic ring 300 are defined as side faces.

[0053] It is worth noting that the number of the threading holes 11 and the connecting holes 301 can be configured according to the actual application scenario, such as the number and specifications of the cables 400, and this application does not impose any restrictions on this.

[0054] When the interface assembly 100 needs to be assembled, the magnetic ring 300 can be snap-fitted and fixed to the fastener 20, and the cable 400 can be passed through the magnetic ring 300 and the base 10, and then the base 10 can be fixed on the shell 500. In this way, the relative fixation between the magnetic ring 300, the base 10 and the cable 400 can be achieved. The assembly process is simple and convenient to assemble, and it can ensure that the magnetic ring 300 is fixed in the specified position, realize the quantification of the relative position between the magnetic ring 300 and the cable 400, improve the assembly consistency, and thus improve the production efficiency and production quality.

[0055] In one embodiment of the present application, the latch 20 and the base 10 are integrally formed of a plastic material, so that the latch 20 has a certain elasticity, which facilitates the snap-fit assembly of the magnetic ring 300 .

[0056] In one embodiment of the present application, the number of the fasteners 20 is greater than or equal to 2, and the plurality of fasteners 20 are distributed at intervals along the circumference of the base 10 .

[0057] It can be understood that there is a gap between the multiple latches 20. On the one hand, it can leave space for the latches 20 to bend and deform, facilitating the snap-on assembly of the magnetic ring 300, and on the other hand, it can reduce the overall weight of the connector 200.

[0058] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, the clip 20 includes a positioning portion 21 and a clamping portion 22. The positioning portion 21 extends along the thickness direction of the base 10, and the positioning portions 21 of the multiple clips 20 are distributed around the assembly area 12. One end of the positioning portion 21 is connected to the base 10, and the clamping portion 22 is provided at the other end of the positioning portion 21. The clamping portion 22 is provided in a direction protruding toward the assembly area 12. The positioning portion 21 abuts against the side of the magnetic ring 300, and the clamping portion 22 and the base 10 cooperate to abut the end surfaces of the magnetic ring 300.

[0059] It can be understood that the fastener 20 cooperates with the positioning portion 21 and the clamping portion 22 to fix the side and end faces of the magnetic ring 300 so that the magnetic ring 300 can be more stably fixed on the base 10.

[0060] When the magnetic ring 300 needs to be clamped between multiple clips 20, the magnetic ring 300 can be held against the side of the clamping portion 22 away from the assembly area 12, and force is applied to the magnetic ring 300 to move it toward the assembly area 12. Under the action of force, the positioning portion 21 of each clip 20 can bend and deform in a direction away from the assembly area 12, so that the magnetic ring 300 can be clamped between the multiple clips 20. After that, the positioning portion 21 of each clip 20 can automatically recover its deformation and be clamped against the side of the magnetic ring 300, and the clamping portion 22 of each clip 20 can be clamped against the end face of the magnetic ring 300, thereby fixing the magnetic ring 300. The above-mentioned clamping assembly method of the magnetic ring 300 is simple and direct, easy to operate, and beneficial to improving assembly efficiency and production efficiency.

[0061] On the other hand, a detachable connection is formed between the magnetic ring 300 and multiple fasteners 20. When the assembled magnetic ring 300 needs to be disassembled, force can be applied to the magnetic ring 300 at the distance between each fastener 20, so that the magnetic ring 300 moves in the direction of separation from the assembly area 12, and the positioning part 21 of each fastener 20 is bent and deformed in the direction away from the assembly area 12, thereby removing the magnetic ring 300 from the assembly area 12, which makes it convenient for users to disassemble and repair the equipment later.

[0062] In one embodiment of the present application, an inclined surface 221 is provided on a side of the clamping portion 22 away from the base 10 . The inclined surface 221 is inclined toward the assembly area 12 and the base 10 .

[0063] When the magnetic ring 300 is clamped between multiple fasteners 20, the magnetic ring 300 can be supported by the inclined surface 221 of the clamping portion 22. As the magnetic ring 300 moves toward the direction close to the assembly area 12, the magnetic ring 300 can use the inclined surface 221 to support the positioning portion 21 of each fastener 20, so that the magnetic ring 300 can be more easily clamped between the multiple fasteners 20, thereby facilitating the clamping assembly of the magnetic ring 300.

[0064] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, the plurality of latches 20 include a plurality of first latches 23 and a plurality of second latches 24, wherein the plurality of first latches 23 are spaced apart along a first direction (i.e., the X-axis direction in the figure), and the plurality of second latches 24 are spaced apart along a second direction (i.e., the Y-axis direction in the figure). An angle is formed between the first direction and the second direction. The plurality of first latches 23 abut against both sides of the magnetic ring 300 along the first direction, and the plurality of second latches 24 abut against both sides of the magnetic ring 300 along the second direction.

[0065] It can be understood that the positioning portions 21 of the two first latches 23 cooperate to abut against both sides of the magnetic ring 300 in the first direction to position the magnetic ring 300 in the first direction. The positioning portions 21 of the two second latches 24 cooperate to abut against both sides of the magnetic ring 300 in the second direction to position the magnetic ring 300 in the second direction. The first latches 23 and the second latches 24 cooperate to position the magnetic ring 300 from different directions, thereby improving the installation stability of the magnetic ring 300 and preventing the magnetic ring 300 from falling during use.

[0066] like Figure 3 and Figure 5 As shown, in one embodiment of the present application, the number of assembly areas 12 is greater than or equal to 2, and the multiple assembly areas 12 are spaced apart along the first direction. Each assembly area 12 is correspondingly configured with multiple first fasteners 23 and multiple second fasteners 24. For example, the number of first fasteners 23 configured in each assembly area 12 is 2, and the number of second fasteners 24 configured in each assembly area 12 is 2.

[0067] It is understood that the multiple assembly areas 12 can respectively accommodate multiple magnetic rings 300, and the multiple first latches 23 and the multiple second latches 24 can cooperate to fix the magnetic rings 300 located in the corresponding assembly areas 12, so as to allow the connector 200 to install a larger number of magnetic rings 300. It is worth noting that the number of magnetic rings 300 can be configured according to actual application scenarios, such as the number and specifications of cables 400, and this application does not limit this.

[0068] In this embodiment, the cables 400 used in the connector 200 are photovoltaic MC4 connector cables. These cables are arranged in pairs, and this embodiment uses two pairs of cables 400 as an example, meaning the total number of cables 400 is four. Each magnetic ring 300 corresponds to a pair of cables 400, and the total number of magnetic rings 300 is two.

[0069] The number of threading holes 11 provided on the base 10 is 4. The number of assembly areas 12 provided on the base 10 is 2, and each assembly area 12 is respectively configured with two first fasteners 23 and two second fasteners 24.

[0070] Two magnetic rings 300 are installed in two assembly areas 12, respectively. Each magnetic ring 300 is fixed between two corresponding first fasteners 23 and two second fasteners 24. Each magnetic ring 300 is provided with two communication holes 301. The four communication holes 301 are respectively connected to the four threading holes 11. The four cables 400 are respectively inserted into the four threading holes 11 and the four communication holes 301.

[0071] like Figure 5 and Figure 6 As shown, for ease of understanding, the two magnetic rings 300 are defined as magnetic ring 300a and magnetic ring 300b. The two assembly areas 12 are defined as assembly area 12a and assembly area 12b. Assembly area 12a is configured with first and second latches 23a, 23b, 24a, and 24b. Assembly area 12b is configured with first and second latches 23c, 23d, 24c, and 24d.

[0072] The first latch 23a, the first latch 23b, the second latch 24a, and the second latch 24b are distributed around the magnetic ring 300a and secure the magnetic ring 300a so that the magnetic ring 300a is securely mounted in the assembly area 12a. The first latch 23b, the first latch 23d, the second latch 24c, and the second latch 24d are distributed around the magnetic ring 300b and secure the magnetic ring 300b so that the magnetic ring 300b is securely mounted in the assembly area 12b.

[0073] In one embodiment of the present application, the plurality of first fasteners 23 located between two adjacent assembly areas 12 are spaced apart along the second direction. By spacing the adjacent plurality of first fasteners 23 along the second direction, the spatial layout between the plurality of first fasteners 23 is optimized, the spacing between the plurality of assembly areas 12 is shortened, and space utilization is improved.

[0074] In this embodiment, assembly area 12a and assembly area 12b are two adjacent assembly areas 12, and first latching member 23b and first latching member 23c are located between assembly area 12a and assembly area 12b. First latching member 23b and first latching member 23c are spaced apart from each other along the second direction. This reduces the distance between assembly area 12a and assembly area 12b, thereby improving space utilization.

[0075] In one embodiment of the present application, one side of the first latch 23 is in close proximity to the corresponding assembly area 12 to support the magnetic ring 300 located in the corresponding assembly area 12. The other side of the first latch 23 is spaced apart from the adjacent other assembly areas 12, thereby providing a gap between the first latch 23 and the magnetic ring 300 located in the adjacent other assembly areas 12. This allows a certain amount of space to bend and deform on the side of the first latch 23 facing away from the corresponding assembly area 12, preventing the first latch 23 from becoming stuck.

[0076] In the example of this embodiment, the assembly area 12a and the assembly area 12b are two adjacent assembly areas 12, and the first latch 23b and the first latch 23c are located between the assembly area 12a and the assembly area 12b. One side of the first latch 23b is close to the assembly area 12a and abuts the magnetic ring 300a, while the other side of the first latch 23b is spaced apart from the assembly area 12b. One side of the first latch 23c is close to the assembly area 12b and abuts the magnetic ring 300b, while the other side of the first latch 23c is spaced apart from the assembly area 12a.

[0077] In this way, when the magnetic ring 300a has been installed and the magnetic ring 300b has not been installed, a distance is left between the first fastener 23c and the magnetic ring 300a. When the magnetic ring 300b needs to be installed, the first fastener 23c is allowed to bend and deform in a direction away from the assembly area 12b (i.e., close to the magnetic ring 300a), so that the magnetic ring 300b can be installed into the assembly area 12b after the first fastener 23c is deformed.

[0078] When the magnetic ring 300b has been installed and the magnetic ring 300a has not been installed, a distance is left between the first fastener 23b and the magnetic ring 300b. When the magnetic ring 300a needs to be installed, the first fastener 23b is allowed to bend and deform in a direction away from the assembly area 12a (i.e., close to the magnetic ring 300b), so that the magnetic ring 300a can be installed into the assembly area 12a after the first fastener 23b is deformed.

[0079] When the magnetic ring 300a and the magnetic ring 300b have been installed and the installed magnetic ring 300a needs to be removed, a distance is left between the first fastener 23b and the magnetic ring 300b, allowing the first fastener 23b to bend and deform in a direction away from the assembly area 12a (i.e., close to the magnetic ring 300b), making it convenient for the magnetic ring 300a to be separated from the assembly area 12a after the first fastener 23b is deformed.

[0080] When the magnetic ring 300a and the magnetic ring 300b have been installed and the installed magnetic ring 300b needs to be removed, a distance is left between the first fastener 23c and the magnetic ring 300a, allowing the first fastener 23c to bend and deform in a direction away from the assembly area 12b (i.e., close to the magnetic ring 300a), making it convenient for the magnetic ring 300b to detach from the assembly area 12b after the first fastener 23c is deformed.

[0081] In this way, by designing the first fastener 23 to be positioned between two adjacent assembly areas 12 , the installation or removal of the magnetic rings 300 in the two adjacent assembly areas 12 can be facilitated, thereby improving the efficiency of installation and removal.

[0082] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, the base 10 is provided with mounting slots 13, which are distributed along the circumference of the base 10 and are used for mounting with the housing 500. For example, the mounting slots 13 are formed by inward depressions on the circumference of the base 10. The number of mounting slots 13 is greater than or equal to two, and the plurality of mounting slots 13 are spaced apart along the thickness direction of the base 10. The connector 200 can be embedded in the housing 500 through the mounting slots 13. The mounting slots 13 and the housing 500 can be fixed together using adhesive to achieve a waterproof effect.

[0083] In one embodiment of the present application, a fixing tube 14 is provided on a side of the base 10 away from the fastener 20 . The number of the fixing tubes 14 is the same as the number of the cables 400 . The fixing tubes 14 are used for the cables 400 to pass through and provide support for the cables 400 .

[0084] like Figure 1 and Figure 2 As shown, the present application also provides a photovoltaic inverter 1000, which includes a housing 500, an interface assembly 100, and a circuit assembly 600. The interface assembly 100 includes a connector 200, a magnetic ring 300, and a cable 400. The circuit assembly 600 is disposed in the housing 500, the connector 200 is embedded and fixed in the housing 500, and the magnetic ring 300 is fixed to the connector 200.

[0085] Illustratively, a mounting opening is provided on one side of the housing 500, and the connector 200 is embedded and fixed in the mounting opening, so that one end of the connector 200 is located inside the housing 500 and the other end of the connector 200 is located outside the housing 500. The magnetic ring 300 is mounted on the end of the connector 200 located inside the housing 500. The cable 400 is inserted through the connector 200, the magnetic ring 300, and the housing 500. The end of the cable 400 located inside the housing 500 is connected to the circuit assembly 600. The end of the cable 400 exposed outside the housing 500 is provided with a connector 403. The cable 400 is connected to a device outside the photovoltaic inverter 1000. The magnetic ring 300 is sleeved on the magnetic ring 300 to achieve EMC anti-interference function.
