Technical Field

[0001] This utility model relates to the field of automotive connector technology, specifically to a hardware structure. Background Technology

[0002] Automotive electrical connection hardware ensures the vehicle's power distribution, control signal transmission, and high-voltage safety through reliable electrical connections, signal transmission, and system protection. It also provides modular maintenance interfaces and adaptability to harsh environments. With the increasing popularity of new energy vehicles, the proportion of gasoline vehicles is gradually decreasing while the proportion of electric vehicles is gradually increasing. New energy vehicles require high-current electrical connections to meet the demands of high-voltage, high-current transmission, safety protection, and lightweight design, supporting high-efficiency power systems and fast-charging technology. Most of these hardware components include fuses and conductive sheets connected to the fuses. In existing technologies, the material thickness of fuses and conductive sheets is mostly 0.8mm, requiring a 0.6mm gap to be punched between the two conductive sheets. However, new energy vehicles require high-current electrical connections, necessitating increased thickness of fuses and conductive sheets. When the thickness of the fuses and conductive sheets is increased, it becomes impossible to punch a gap between the two conductive sheets. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect that after the thickness of the fuse and conductive sheet is increased in the prior art, it is impossible to punch out the gap between the two conductive sheets. Thus, a hardware structure that can overcome the defect that after the thickness of the fuse and conductive sheet is increased in the prior art, it is impossible to punch out the gap between the two conductive sheets is provided.

[0004] Therefore, this utility model provides a hardware structure, including at least two adjacent hardware pieces, which are flexibly connected to each other. Each hardware piece includes a fusible link and a conductive link connected to the fusible link. The conductive link has a slot in the middle for insertion into an external pin. The adjacent hardware pieces can be bent and overlapped.

[0005] Furthermore: the hardware sheet consists of two pieces, namely a first hardware sheet and a second hardware sheet. The first hardware sheet is provided with a first conductive sheet, and the second hardware sheet is provided with a second conductive sheet. The first hardware sheet and the second hardware sheet are flexibly connected and can be rotated 180° to overlap.

[0006] Furthermore: the hardware sheet consists of two pieces, namely a first hardware sheet, a second hardware sheet, and a third hardware sheet. The first hardware sheet is provided with a first conductive sheet, the second hardware sheet is provided with a second conductive sheet, and the third hardware sheet is provided with a third conductive sheet. The first hardware sheet, the second hardware sheet, and the third hardware sheet are flexibly connected and can be rotated 180° to overlap.

[0007] Furthermore: the conductive sheet includes a first connecting piece and a second connecting piece disposed opposite to each other, and the slot is located between the first connecting piece and the second connecting piece.

[0008] Furthermore: the first connecting piece is provided with a first extension, and the second connecting piece is provided with a second extension, the first extension and the second extension being interference-fitted with the external pin.

[0009] Furthermore, a partition groove is provided between the first conductive sheet, the second conductive sheet, and the third conductive sheet.

[0010] The technical solution of this utility model has the following advantages:

[0011] 1. This utility model provides a hardware structure, which includes multiple hardware sheets. Each hardware sheet consists of a fuse and a conductive sheet. Slots for inserting pins are formed between the conductive sheets. During the manufacturing process, multiple hardware sheets are punched out from a metal plate with a thickness of 0.8mm. Then, the hardware sheets on both sides are bent 180° clockwise or counterclockwise to form multiple times the thickness. This can effectively increase the cross-sectional area of ​​the fuse and conductive sheets, and also solve the problem that after the thickness of the fuse and conductive sheets is increased, it is impossible to punch out the gap between two conductive sheets. Large currents require a larger cross-sectional area, otherwise it is easy to cause serious heat generation, thereby causing damage to the parts. Attached Figure Description

[0025] Example

[0026] This embodiment provides a hardware structure, including at least two adjacent hardware sheets 1, which are flexibly connected to each other. Each hardware sheet 1 includes a fusible link 11 and a conductive link 12 connected to the fusible link 11. The conductive link 12 has a slot 2 in the middle for interlocking with an external pin. The adjacent hardware can be bent and overlapped.

[0027] The specific improvements mentioned above are as follows: Figures 1-3 As shown, the hardware structure includes multiple hardware sheets 1. Each hardware sheet 1 consists of a fuse 11 and a conductive sheet 12. Slots for inserting pins are formed between the conductive sheets 12. During the manufacturing process, multiple hardware sheets 1 are punched out from a metal plate with a thickness of 0.8mm. Then, the hardware sheets 1 on both sides are bent 180° clockwise or counterclockwise to form multiple times the thickness. This can effectively increase the cross-sectional area of ​​the fuse 11 and the conductive sheet 12. It can also solve the problem that after the thickness of the fuse and the conductive sheet 12 is increased, it is impossible to punch a gap between the two conductive sheets 12. Large current requires a larger cross-sectional area, otherwise it is easy to cause serious heat generation, which will damage the parts. The size of the punched gap is related to the thickness. When the thickness of the fuse 11 and the conductive sheet 12 is too thick and the gap is too small, it is easy to break and not manufacturable. Generally, with a thickness of 0.8mm, the maximum punched gap can only be 0.6mm. With a thickness of 2.4mm, it is impossible to punch a gap of 0.6mm.

[0028] Based on the above embodiment: the hardware sheet is provided with two pieces, namely the first hardware sheet 3 and the second hardware sheet 4. The first hardware sheet 3 is provided with a first conductive sheet 31, and the second hardware sheet 4 is provided with a second conductive sheet 41. The first hardware sheet 3 and the second hardware sheet 4 are flexibly connected and can be rotated 180° to overlap.

[0029] Based on the above embodiment: the hardware sheet is provided in two pieces, namely the first hardware sheet 3, the second hardware sheet 4 and the third hardware sheet 5. The first hardware sheet 3 is provided with a first conductive sheet 31, the second hardware sheet 4 is provided with a second conductive sheet 41, and the third hardware sheet 5 is provided with a third conductive sheet 51. The first hardware sheet 3, the second hardware sheet 4 and the third hardware sheet 5 are flexibly connected and can be rotated 180° to overlap.

[0030] The specific improvements mentioned above are as follows: Figures 1-3 As shown, the hardware sheet 1 can be set to 2 or 3 pieces. The principle is the same: two or three hardware sheets 1 are stamped out on a metal plate, then 0.6mm slots are cut out, and finally the hardware sheets 1 are flipped and overlapped.

[0031] Based on the above embodiments: the conductive sheet 12 includes a first connecting piece 13 and a second connecting piece 14 disposed opposite to each other, and the slot 2 is located between the first connecting piece 13 and the second connecting piece 14.

[0032] Based on the above embodiments: the first connecting piece 13 is provided with a first extension 6, the second connecting piece 14 is provided with a second extension 7, and the first extension 6 and the second extension 7 are interference-fitted with the external pin.

[0033] Based on the above embodiments: a partition groove 8 is provided between the first conductive sheet 31, the second conductive sheet 41 and the third conductive sheet 51.

[0034] The specific improvements mentioned above are as follows: Figures 3-6 As shown, the conductive sheet 12 is composed of a first connecting piece 13 and a second connecting piece 14. The slot 2 is disposed between the first connecting piece 13 and the second connecting piece 14. The first connecting piece 13 and the second connecting piece 14 are respectively provided with a first extension 6 and a second extension 7. The distance between the first extension 6 and the second extension 7 is 0.6mm. The slot 2 formed between the first extension 6 and the second extension 7 is used for the insertion of external pins to form a conductive connection. By setting the partition groove 8, gaps can exist between the first connecting piece 13 and the second connecting piece 14 at adjacent positions, so that the first hardware sheet 3, the second hardware sheet 4 and the third hardware sheet 5 can be folded later.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
