Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material connectors, in particular to a universal copper clip. Background Art
[0002] It is known that in modules, due to limitations in bonding quality, bonding damage, equivalent effective contact area of solder joints, current carrying differences between wires of different diameters and lengths, and difficulty in optimizing heat distribution, bonding wires have become one of the shortcomings that affect module reliability performance. Clip (copper clip) or Lead frame (lead frame) technology can improve the above performance to a large extent, thereby further increasing design redundancy and improving reliability. However, the production of Clip or Lead frame requires a considerable mold cost, and each requires a corresponding exclusive mold, which is difficult to be used interchangeably between different molds. In particular, multiple designs may be generated during the R&D stage, resulting in increased material preparation time and extended R&D cycle. After the product is finalized, the remaining designs become disposable products, further increasing R&D costs. All of these have caused a certain degree of waste. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.
[0024] Due to the limitations of existing technologies in bonding quality, bonding damage, equivalent effective contact area of solder joints, current carrying differences between wires of different diameters and lengths, and difficulty in optimizing heat distribution, bonding wires have become one of the shortcomings that affect module reliability performance. Clip or Lead frame technology can improve the above performance to a large extent, thereby further increasing design redundancy and improving reliability. However, the production of Clip or Lead frame requires a considerable amount of mold costs, and each requires a corresponding exclusive mold, which is difficult to be used interchangeably between different molds. In particular, multiple designs may be generated during the R&D stage, resulting in increased material preparation time and extended R&D cycles. After the product is finalized, the remaining designs become disposable products, further increasing R&D costs. All of these have caused a certain degree of waste.
[0025] In response to uncertain design solutions in the R&D stage and the need to verify multiple replacement solutions, a universal copper clip is used to transform existing Clips and Lead frames, or to merge multiple Clips or Lead frames, to achieve rapid response to R&D needs and better cost control.
[0026] like Figure 1-5 As shown, a universal copper clip is an integrated structure, comprising: a flat plate 1 and an inclined plate 2;
[0027] Four inclined plates 2 are provided and are respectively connected to both sides of the flat plate 1 through connecting blocks 3 , and an open hole is provided between the flat plate 1 and the inclined plates 2 for adjusting the angle of the inclined plates 2 .
[0028] Each inclined plate 2 includes an adjusting plate 4 and a bottom plate 5 , which are sequentially connected and integrated, and one end of the adjusting plate 4 is integrally connected to the connecting block 3 .
[0029] The angle of the inclined plate 2 can be adjusted around the two ends of the adjustment plate 4, and the horizontal angle between the adjustment plate 4 and the flat plate 1 is A. A clamped object 6 is arranged in the gap between the flat plate 1 and the bottom plate 5.
[0030] The length of the bottom plate 5 is adjustable, and the length is W. By adjusting the length of the connecting block 3, the angle A of the four inclined plates 2 and the length of the bottom plate 5 are adjusted within a suitable range, and the length W is changed, thereby achieving clamping of the clamped objects 6 of different distances, thicknesses and widths.
[0031] The material of the flat plate 1 and the inclined plate 2 is a conductor or an insulator, which is used to adapt to the material of the clamped object 6. By using different materials, it can be used in different scenarios. The flat plate 1, the inclined plate 2 and the clamped object 6 are connected by sintering, brazing, laser welding or bonding.
[0032] In actual use, the following embodiments are provided: Example
[0033] like Figure 3 As shown, facing the connection object with a long distance, the angle A is adjusted to a smaller value, and then the length W of the bottom plate 5 is adjusted to fit and connect to the clamped object 6 to perform the connection. Example
[0034] like Figure 4 As shown, facing the connection objects with a relatively close spacing, the angle A is adjusted to a larger value, and then the length W of the bottom plate 5 is adjusted to fit and connect to the clamped object 6 to perform the connection. Example
[0035] like Figure 5 As shown, facing the oblique connection object, adjust the angle A, and then adjust the length W of the bottom plate 5 to fit the clamped object 6 to perform the connection.
[0036] The working principle of the utility model is as follows:
[0037] When it is actually used, the four inclined plates 2 are folded and the length of the connecting block 3 is adjusted. At this time, a horizontal angle of A is folded out, and then the clamped object 6 is clamped on the bottom plate 5, and then it is connected to the clamped object 6.
[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
