Description

Technical Field

[0001] This utility model relates to the field of automotive electronics technology, specifically to a U-shaped sheet material that is easy to fold. Background Technology

[0002] With the development of electronic technology, various electronic components have been more widely used, especially inductors. Among these, high-current integrated inductors are widely used. They are formed in one piece using a special die-casting process with coils wound with flat or round copper wire and iron powder, exhibiting characteristics such as high current resistance and low impedance. Before forming, the inductor coils need to be individually spot-welded to the sheet material, followed by die-casting of insulating iron powder, and then silver or tin plating on the inductor's electrode leads. Finally, a cutting machine separates the inductor from the sheet material. This method of individually spot-welding the leads on the inductor coils to the sheet material carries the risk of open circuits, which can easily increase the defect rate. Therefore, a U-shaped lead sheet material that is easy to fold is provided to solve these problems. Utility Model Content

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figures 1-3The present invention provides a U-shaped sheet material that is easy to fold, comprising: a sheet body 1, with spot welding end leads 2 symmetrically arranged on the inner side of the sheet body 1, a foldable U-shaped sheet body 3 connected to one side of the spot welding end leads 2, a limiting foot 4 connected to the end of the spot welding end leads 2 adjacent to the U-shaped sheet body 3, and the U-shaped sheet body 3 being folded and connected to the coil spot welding terminal 10.

[0018] Among them, the coil spot welding terminal 10 has a flat structure. One end of the coil spot welding terminal 10 is connected to the end of the coil body 9. Two flat coil spot welding terminals 10 are led out from the end of the coil body 9. The coil spot welding terminal 10 is folded and spot welded to the U-foot body 3. The side of the sheet body 1 is provided with positioning holes 5. The number of positioning holes 5 is set to several. The sheet body 1 is provided with deformation holes 7 on one side of the positioning holes 5. The positioning holes 5 facilitate the positioning of the sheet body 1 on the mold. A triangular opening 8 is provided on one side inside the deformation hole 7. A support piece 6 is connected to the inside of the sheet body 1. The end of the support piece 6 is directly opposite the deformation hole 7. The deformation hole 7 and the triangular opening 8 can increase the deformation capacity of the support piece 6, thereby effectively preventing breakage. The sheet body 1, the spot welding terminal lead-out 2, the U-foot body 3 and the limiting foot 4 are integrally formed. When using the material sheet of this design, the main body 1 of the material sheet must first be prepared. Then, the coil spot welding terminals 10 connected to both ends of the circular coil body 9 are offset. Next, the coil spot welding terminals 10 are placed on the U-pin body 3, and the U-pin body 3 on the main body 1 is bent to wrap around the coil spot welding terminals 10 and spot welded. The welding method can be resistance welding or laser spot welding. In this new design, the U-pin body 3 on the spot welding end lead 2 of the material sheet wraps around the coil spot welding terminals 10 before spot welding, which mainly effectively prevents the risk of open circuit and is suitable for high-end integrated inductors.
