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%.

To disclose a wiring structure having a fuse assembly, and a manufacturing method of the same.SOLUTION: A wiring structure comprises a wire harness 10 and a fuse assembly 20. The wire harness in which a plurality of wiring lines is arranged and extended in an insulation wire is prepared, and the insulation wire coated by one end of each wiring line and an outer peripheral side of one end of each wiring line in the wire harness is cut, and the insulation wire coated by one end of each wiring line and the outer peripheral side of one end of each wiring line is extended so as to be folded from the wire harness. A fuse prepares a fuse assembly processed to an insulation sleeve 202, and one end of the fuse is welded to one end of each wiring line after the cutting. In the present invention, by welding the fuse assembly to one end of each wiring line folded to an outside from the wire harness, a stress concentration can be prevented, and a state where the fuse assembly and a welding portion of each wiring line are separated can be reduced.SELECTED DRAWING: Figure 2

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.

This invention belongs to the field of circuit protection technology, specifically relating to a protection element, equivalent to a high-current protection element consisting of two independent protection elements connected in parallel. The high-current protection element is considered as a back-side circuit module and a front-side circuit module stacked on the front and back sides of a ceramic substrate, connected to an external circuit via supporting conductor terminals. This invention features fuse assemblies on both the front and back sides of the ceramic substrate, enabling dual-path current flow. The supporting conductor terminals serve as the input ports for external current or voltage, while also supporting the ceramic substrate. Ultimately, the high-current protection element achieves high current carrying capacity through two parallel-connected fuse assemblies. This approach avoids the need for novel fuse materials with suitable melting points and low resistivity, while also preventing the increased risk of rapid fuse failure due to excessively increasing fuse size and thickness.
