Description

Technical Field

[0001] This utility model belongs to the field of inverters, specifically relating to a convenient wiring structure for inverters and a photovoltaic inverter. Background Technology

[0002] With the rapid development of electronic devices, the demand for electrical connections between internal components is increasing.

[0003] Inverters typically include inductor boards, driver boards, and other components such as the main board. In the original design structure, the electrical beams often pass directly from the upper board to the lower board without a dedicated structure to manage and fix them. This results in a messy overall layout of the electrical beams, which can easily lead to knots or even mutual interference between the beams, seriously affecting the overall performance and safety. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a convenient wiring structure for inverters and a photovoltaic inverter.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a convenient wiring structure for inverters, which is used to electrically connect devices installed on the upper plate and the lower plate respectively through an electric beam. It includes: a mounting base, which is disposed on the lower plate. A semi-sealed cavity is formed in the mounting base. One side of the opening of the semi-sealed cavity faces the upper plate, and the other side faces the sandwich between the upper plate and the lower plate, so that the electric beam can extend into the semi-sealed cavity in a horizontal posture.

[0006] The fasteners are symmetrically arranged at the opening end of the semi-sealed cavity facing the interlayer, and the fasteners are used to limit the displacement of the electric beam relative to the mounting base;

[0007] A wire terminal is detachably connected to the semi-sealed cavity. One end of the wire terminal is electrically connected to the upper plate, and the other end of the wire terminal is connected to the electrical beam and fixed in the semi-sealed cavity by the buckle.

[0008] In the aforementioned convenient wiring structure for inverters, the semi-sealed cavity includes a vertical guide groove and a horizontal guide groove. A locking buckle is connected inside the vertical guide groove. The locking buckle movably passes through the wire terminal and presses it against the vertical guide groove. The horizontal guide groove is connected to the vertical guide groove, and the fastener is movably disposed at the opening end of the horizontal guide groove away from the vertical guide groove.

[0009] In the above-mentioned convenient wiring structure applied to inverters, an avoidance groove is also provided between the side wall of the horizontal guide groove and the fastener, and the avoidance groove is used to provide deformation space for the fastener.

[0010] In the aforementioned convenient wiring structure for inverters, the end of the pressure terminal is formed with a cylindrical connecting portion, and a connecting hole is provided in the connecting portion, and the electrical beam is connected in the connecting hole.

[0011] In the above-mentioned convenient wiring structure applied to inverters, a connecting post is provided in the vertical guide groove, and a threaded hole is provided in the connecting post. A positioning plate is formed at the end of the pressure terminal away from the connecting part. When the connecting post is sleeved and flush with its upper end surface, the positioning plate can be connected to the threaded hole by fasteners and pressed against the positioning plate.

[0012] The technical solution adopted by this utility model to solve its technical problem is to also propose a photovoltaic inverter, including the above-mentioned convenient wiring structure applied to the inverter.

[0013] Compared with the prior art, the advantages of this utility model are that the semi-sealed cavity design protects the electric beam from the influence of the external environment and extends its service life; at the same time, the use of snap fasteners and wire terminals effectively prevents the electric beam from moving in the mounting base, enhances the stability of the wiring, and the overall structure is compact, which is convenient for installation and maintenance, improves work efficiency, and also achieves neat arrangement of the electric beam, reduces interference between electric beams, and facilitates subsequent maintenance and inspection.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] Example 1:

[0024] like Figures 1 to 3 As shown, a convenient wiring structure for inverters is used to electrically connect devices mounted on an upper plate 1 and a lower plate 2 via an electrical beam. The structure includes: a mounting base 3 disposed on the lower plate 2, with a semi-sealed cavity 30 formed within it. One opening of the semi-sealed cavity 30 faces the upper plate 1, and the other opening faces the space between the upper plate 1 and the lower plate 2, allowing the electrical beam to extend horizontally into the semi-sealed cavity 30; a locking member 4 symmetrically disposed at the opening of the semi-sealed cavity 30 facing the space, used to limit the displacement of the electrical beam relative to the mounting base 3; and a wire terminal 5 detachably connected within the semi-sealed cavity 30, one end of which is electrically connected to the upper plate, and the other end of which is connected to the electrical beam and fixed within the semi-sealed cavity 30 by the locking member 4.

[0025] Compared to the traditional connection between the upper plate 1 and the lower plate 2, where the electrical beam is often connected by passing it from the top to the bottom, this method can lead to disorganization and even interference when there are many electrical beams. To address this issue, this embodiment fixes the mounting base 3 to the lower plate 2. After connecting to the lower plate 2, one end of the electrical beam can extend horizontally into the semi-sealed cavity 30. During this process, the presence of the latching component 4 allows the electrical beam to be initially positioned after entering the cavity, preventing unnecessary movement during subsequent operations. The crimping terminal 5 is detachably installed inside the semi-sealed cavity 30, and one end of the crimping terminal 5 is already electrically connected to the upper plate 1. Since one end of the electrical beam is already electrically connected to the components mounted on the lower plate 2, the electrical beam can connect to the other end of the crimping terminal 5 after extending into the semi-sealed cavity 30. Combined with the further fixation of the electrical beam by the latching component 4, the electrical beam is securely confined within the semi-sealed cavity 30, ensuring a reliable connection between the electrical beam and the upper and lower plates. Therefore, the semi-sealed cavity 30 design in this embodiment can isolate dust and moisture in the external environment to a certain extent, protect the electric beam from external factors, and extend its service life. At the same time, the use of the snap fastener 4 in conjunction with the wire clamping terminal 5 effectively prevents the electric beam from moving within the mounting base 3, enhances the stability of the wiring, and has a compact overall structure that is easy to install and maintain. While improving work efficiency, it also achieves a neat arrangement of the electric beam, reduces interference between electric beams, and facilitates subsequent maintenance and inspection.

[0026] The semi-sealed cavity 30 includes a vertical guide groove 300 and a horizontal guide groove 301. A locking buckle 300a is connected inside the vertical guide groove 300. The locking buckle 300a movably passes through the wire terminal 5 and presses it into the vertical guide groove 300. The horizontal guide groove 301 is connected to the vertical guide groove 300. The fastener 4 is movably disposed at the opening end of the horizontal guide groove 301 away from the vertical guide groove 300.

[0027] like Figures 2 to 3 As shown, both the vertical guide groove 300 and the horizontal guide groove 301 are arranged parallel to the upper and lower plates 2. Before the upper and lower plates 2 are connected, the locking buckle 300a can pass through the crimp terminal 5 and confine it within the semi-sealed cavity 30, ensuring the stability of the subsequent connection between the electrical bundle and the connecting part 50. It also facilitates the convenient installation and removal of the crimp terminal 5 and the mounting base 3, making subsequent maintenance and replacement easier. Furthermore, in this embodiment, the crimp terminal 5 is L-shaped, and the horizontal guide groove 301 and the vertical guide groove 300 can also limit the position of the crimp terminal 5, while also ensuring the connection between the connecting part 50 and the mounting base 3. Figure 3 The right end opening of the horizontal guide groove 301 shown is aligned to ensure that the electric beam can be connected to the connecting part 50 at the same time, and is also pressed and fixed by the buckle 4. The overall structure is compact, reducing assembly time and complexity.

[0028] Furthermore, such as Figure 3 As shown, since the latching component 4 in this embodiment has the same latching structure and working principle as commonly used in machinery, it will not be described again here. Therefore, the latching component 4 can be applied to electric beams of different diameters, increasing the versatility and adaptability of the structure, so as to facilitate its application in various scenarios. Furthermore, a clearance groove 301a is provided between the side wall of the horizontal guide groove 301 and the latching component 4. The design of this clearance groove 301a makes the operation of the latching component 4 smoother, and the user will not feel any jamming or excessive resistance when closing the latching component 4, improving the convenience of installation and maintenance and enhancing the user experience.

[0029] A connecting post 300b is provided in the vertical guide groove 300. A threaded hole 300c is provided in the connecting post 300b. A positioning plate 51 is formed at the end of the pressure terminal 5 away from the connecting part 50. When the connecting post 300b is sleeved and flush with its upper end surface, the positioning plate 51 can be connected to the threaded hole 300c by fasteners and pressed against the positioning plate 51.

[0030] Continue to refer to Figure 3As the locking buckle 300a presses the wire terminal 5 into the semi-sealed cavity 30, the positioning plate 51 on the wire terminal 5 is also fitted onto the connecting post 300b, further limiting the position of the wire terminal 5. After ensuring that the upper surface of the positioning plate 51 and the connecting post 300b are flush, a fastener (such as a screw) is passed through the positioning plate 51 and screwed into the threaded hole 300c in the connecting post 300b until the fastener is pressed against the positioning plate 51, so that the wire terminal 5 is firmly fixed in the vertical guide groove 300, thereby realizing the electrical connection between the wire terminal 5 and the upper plate 1. After ensuring that the electrical beam is connected in the connecting hole 500, a stable connection between the upper plate 1 and the lower plate 2 is achieved.

[0031] Example 2:

[0032] Based on the structure of the first embodiment, the second embodiment can also form a cylindrical connecting portion 50 at the end of the wire terminal 5, and a connecting hole 500 is provided in the connecting portion 50, with the end of the electric beam connected to the connecting hole 500.

[0033] like Figure 3 As shown, the connecting part 50 in this embodiment adopts a cylindrical structure design with a connecting hole 500. The cylindrical connecting part 50 structure has high mechanical strength and can withstand a certain amount of tension and pressure, ensuring that the electric beam will not fall off or be damaged due to external forces during use. The connecting hole 500 allows the end of the electric beam to be directly inserted without complicated wiring steps, simplifying the installation process and improving installation efficiency. It can be seen that the combined effect of the two is conducive to the end of the electric beam being inserted more stably and fixed in the connecting hole 500, reducing the risk of poor contact and improving the reliability of the connection.

[0034] It should be noted that the fasteners in this solution can be replaced by screws, bolts, or other structures.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
