[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of 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 some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only to represent selected embodiments of the present application.

[0024] EMBODIMENT

[0025] In conjunction with Figures 1 to 2 The present embodiment provides a grounding structure for a metal interface, which comprises a metal connector 1 detachably buckled on a base 2 with a metal interface. The metal connector 1 comprises a main frame 11, and a first bending part 12 and a second bending part 13 bent upward and extended outward relative to the main frame 11. The main frame 11 is configured as a Z-shaped plate, corresponding to be detachably buckled on the base 2, so that the first bending part 12 and the second bending part 13 are elastically lapped onto an external metal middle frame (not shown) to define a grounding connection.

[0026] The grounding structure described above, by setting the main frame 11 of the metal connector 1 as a Z-shaped plate, is conducive to being quickly buckled on the base 2, so that the installation and disassembly are more efficient and convenient, providing convenience when maintenance or replacement is needed, and reducing production cost, improving the assembly flexibility of the factory, especially in batch production, which can effectively reduce the error rate.

[0027] Among them, the first bending part 12 and the second bending part 13 are bent upward and extended outward relative to the main frame 11, which can effectively ensure that the metal connector 1 forms a firm contact with the external metal middle frame, and the elastic support of the two bending parts allows the contact surface to be fine-tuned with temperature changes or physical vibrations, so as to always maintain a stable grounding connection, avoiding the loss of grounding effect due to loose grounding.

[0028] Moreover, using the metal connector 1 for grounding not only avoids the use of conductive cloth or conductive foam (such as Figure 4The metal connecting piece 1 can effectively solve the problems of wire breakage and failure caused by the use of conductive cloth and foam, and can enhance the high-temperature resistance, corrosion resistance and mechanical strength of the overall grounding structure. Compared with conductive cloth and foam, the stability of the metal connecting piece 1 is stronger, and the grounding effect can be maintained for a long time. Moreover, the short circuit problem caused by the falling or wire breakage of the conductive material can be significantly improved.

[0029] As shown in Figure 1 In this embodiment, the main frame 11 is provided with a longitudinal connecting portion 14 formed on the outer edge in the length direction, and the connecting portion 14 is translated inwardly relative to the outer edge. In one aspect, the connecting portion 14 plays a good connecting role and is suitable for connecting the bending portion and the main frame 11 to form an integrated structure. In another aspect, the connecting portion 14 is provided with a certain accommodation space during assembly to avoid interference caused by manufacturing tolerances, thermal expansion and other factors. Moreover, through the inward translation, the connecting portion 14 can flexibly adapt to the installation error or slight position change during assembly, so as to ensure that the grounding connection is more reliable and stable.

[0030] Further, the first bending portion 12 is integrally bent on the left side of the connecting portion 14, the second bending portion 13 is integrally bent on the right side of the connecting portion 14, and the two bending portions form an outer octagonal structure. The two bending portions are outwardly expanded to form a more stable grounding connection, which can effectively increase the contact area and improve the grounding effect, and the grounding contact on the external metal middle frame is more uniform and stable.

[0031] Preferably, the first bending portion 12 and the second bending portion 13 are symmetrically arranged on the main frame 11, and the symmetric structure formed by the two bending portions makes the grounding connection more balanced, avoiding the problem of poor grounding caused by asymmetry. In addition, the ends of each bending portion form a support leg 15 arranged in parallel with the connecting portion 14, thereby providing additional support force during assembly. This not only increases the stability of the grounding structure, but also effectively prevents the bending portion from displacement or deformation due to external impact or vibration, thereby maintaining the continuous and stable grounding contact.

[0032] Specifically, the first bending portion 12 and the second bending portion 13 are respectively inclined from the inner side of the outer edge to the outer side of the outer edge to form a support structure that is conducive to grounding connection. Obviously, the angle of inclination can make the grounding portion form a more suitable contact surface with the metal middle frame or the base 2. Compared with the perpendicular or parallel connection mode, the inclined bending can provide stronger contact force and more uniform pressure distribution, thereby ensuring that the grounding effect is more stable.

[0033] As shown in Figure 2As shown in the embodiment, the main frame 11 is provided with a buckle part 16 on both extension plates in the width direction to prevent the main frame 11 from being separated from the base 2. The buckle part 16 can effectively prevent the relative movement or separation between the main frame 11 and the base 2. By using the principle of mechanical locking, the buckle part 16 is buckled or clamped in the corresponding slot on the base 2 to ensure that the main frame 11 is always in a fixed position after installation, thereby avoiding loosening or falling off due to external force or vibration.

[0034] As shown in the embodiment, the main frame 11 is provided with a buckle part 16 on both extension plates in the width direction to prevent the main frame 11 from being separated from the base 2. The buckle part 16 can effectively prevent the relative movement or separation between the main frame 11 and the base 2. By using the principle of mechanical locking, the buckle part 16 is buckled or clamped in the corresponding slot on the base 2 to ensure that the main frame 11 is always in a fixed position after installation, thereby avoiding loosening or falling off due to external force or vibration. Figure 2 As shown in the embodiment, the main frame 11 is provided with a buckle part 16 on both extension plates in the width direction to prevent the main frame 11 from being separated from the base 2. The buckle part 16 can effectively prevent the relative movement or separation between the main frame 11 and the base 2. By using the principle of mechanical locking, the buckle part 16 is buckled or clamped in the corresponding slot on the base 2 to ensure that the main frame 11 is always in a fixed position after installation, thereby avoiding loosening or falling off due to external force or vibration.

[0035] In combination with the above, Figure 3 The utility model provides a kind of electrical appliance, including the base 2 being provided with metal interface, and the grounding structure for metal interface being buckled on the base 2.
