This utility model relates to an ultra-thin rolled copper stamped fuse assembly. The fuse assembly includes a sheet copper substrate made of rolled copper with a thickness in the micrometer range, a first PI thermosetting film and a second PI thermosetting film respectively covering the upper and lower surfaces of the sheet copper substrate; the sheet copper substrate has a wavy fuse portion with a line width of 0.15±0.02mm. This utility model uses a high-precision die-cutting method to punch the ultra-thin rolled copper foil, directly forming a fuse semi-finished product. In particular, the extremely fine fuse portion is punched in one step, avoiding defects such as edge deformation caused by multiple punchings, ensuring stable dimensions and performance of the fuse portion. High-speed rotary die-cutting is then used for efficient and precise production, encapsulating the fuse portion within the film material, exposing the opening area and end area for electrical connection, improving production efficiency and subsequent use efficiency. The overall production efficiency can be increased to 5000pcs / H, and the yield rate to approximately 95%.

This invention discloses a connector, including a female connector and a male connector, which are plugged into each other. The male connector has a switch assembly, and the female connector has a latch, which is movably connected to the female connector. The switch assembly has an unlocked position and a locked position. When the latch is in the unlocked position, the connector's connection is disconnected. When the latch is pressed to the locked position, it abuts against the locking position and triggers the switch assembly, switching the connector's connection to a conductive state. Through the mechanical linkage between the switch assembly and the latch, the connector is ensured to be plugged in and unplugged only when the power is off, eliminating arcing under load and avoiding contact burns and overheating risks. Simultaneously, an integrated fuse assembly can quickly disconnect the faulty branch when a short circuit occurs in the lighting fixture, preventing the fault from affecting other equipment on the same circuit, effectively improving system safety and reliability.
