Fuse wire, device for manufacturing fuse wire and manufacturing method of fuse wire

Abstract

The invention discloses a fuse wire, a device for manufacturing the fuse wire and a manufacturing method of the fuse wire. The device comprises a machine body, a wire outlet frame, a hot melting device, a wire coiling frame and a controller, wherein the wire outlet frame comprises a tin wire frame and a copper wire frame; a tin wire is arranged on the tin wire frame; a copper wire is arranged on the copper wire frame; the hot melting device comprises a heating device and a clamping device; a heating column is arranged on the heating device; the copper wire is attached to the heating column; the clamping device is used for driving the tin wire to extend to the place above the heating column and to be in contact with the copper wire; the controller is arranged on the machine body and is electrically connected with the hot melting device and the wire coiling frame; and the controller is used for controlling the operating temperature of the heating device and the operating speed of the tin wire and the copper wire. Through controlling the operating speed of the tin wire and the copper wire, the hot melting device is used for melting the tin wire onto the copper wire of a laminated structure, so that the middle process is reduced, the process flow is simple, the environmental protection demand is met, the cost is lower, the production efficiency is high, the property is stable and the structure is simple.

Description

technical field [0001] The invention relates to the field of electronic protection components, in particular to a fuse, a device for manufacturing the fuse and a method for manufacturing the fuse. Background technique [0002] Traditional fuses are generally used in electronic products. When the current passing through the fuse is too large, the fuse will be blown to avoid dangers such as overheating and ignition of the circuit. The purpose is to protect people and equipment from injury or even fire due to overcurrent. [0003] There are currently two methods widely used to manufacture fuses, one is the printing and plating process, and the other is threading the wire in the cavity. The printing and plating process provides a method for mass production of fuses. Through the design of the conductive layer pattern, fuses with different currents can be produced, but this process has a fatal flaw, that is, after the printed circuit is sintered and dried, Its compactness is dif...

AI Technical Summary

Problems solved by technology

The printing and plating process provides a method for mass production of fuses. Through the design of the conductive layer pattern, fuses with different currents can be produced, but this process has a fatal flaw, that is, after the printed circuit is sintered and dried, Its compactness is difficult to guarantee, resulting in a large dispersion of product performance. In addition, environmental protection issues caused by electroplating are increasingly concerned

The performance of the fuse made by threading in the cavity is relatively stable, but its production efficiency is low, resulting in relatively high product costs, and it is difficult to produce small or ultra-small fuses
