Integral conductor and double fuse

Abstract

The invention provides an integral type conductor and a double-circuit fuse equipped with the integral type conductor. The integral type conductor is an integrally molded integral member comprising a conductive piece portion and conductive clamping piece portions arranged on the two sides of the conductive piece portion. The double-circuit fuse comprises a top cover, a pedestal and two fuse wiring loops forming in the top cover and the pedestal. Each fuse wiring loop comprises two conductors and a fuse positioned between the two conductors and electrically connected to the conductors; the fuse is arranged in the top cover in a pluggable mode; the conductors are integral type conductors; and the conductive clamping piece portions of the integral conductors are electrically connected to the fuse. According to the application, the integrally molded integral conductors are employed, so the processing and manufacturing efficiency is high, and the manufacturing efficiency of the double-circuit fuse is high; conductive performance between the conductive piece portion and the conductive clamping piece portions of each integral type conductor is reliable and stable; and the conductive reliability of the integral type conductor can be raised, thereby guaranteeing working stability and reliability of the double-circuit fuse.

Description

Technical field [0001] The invention relates to the field of fuses, in particular to an integral electrical conductor and a dual-circuit fuse. Background technique [0002] The fuse mainly includes a conductor and a fuse. When the current in the circuit exceeds the specified value, the fuse is blown by the heat generated by itself, thereby breaking the circuit. It is widely used in high and low voltage power distribution systems, control systems, and electricity Used as a circuit protector for short circuit and overcurrent in equipment and other equipment. At present, equipment in some fields (such as photovoltaic combiner boxes) need to use dozens or even more fuses to realize multi-circuit wiring. At this time, after multiple single-circuit fuses are installed side by side, they occupy The volume is very large, thereby expanding the volume, size and cost of the equipment using single-circuit fuse. [0003] For this reason, the Chinese invention patent application specification ...

AI Technical Summary

Problems solved by technology

[0004] 1. Conductive clips are welded and fixed at the end of each conductor, and the conductive clips are clamped on both sides of the fuse to realize electrical conduction between the conductor and the fuse. It is fixed by welding, and the thickness of the two fuses is inconsistent. Generally speaking, the thickness of the conductive clip is smaller than the thickness of the conductor, so there are problems such as poor welding and low welding efficiency, which will affect the use effect of the two-way fuse

[0005] 2. The insulation effect of the above-mentioned two-way fuse is not good, which is particularly easy to cause a short circuit in the middle and both ends of the two-way wiring in the two-way fuse, which in turn causes the two-way wiring of the two-way fuse to be staggered up and down , and the polarity of the two lines of wiring should be the same at the same end of the two lines of fuses, which will lead to inconsistent wiring of the equipment using the two lines of fuses, and the wiring will be up and down, which will affect the appearance

[0006] 3. The connection structure between the upper cover and the base of the above two-way fuse is: set fixing holes on the left and right sides of the lower end of the upper cover, and set elastic buckles on the left and right sides of the lower end of the base, and put the upper cover down on the base After being put on, the elastic buckle is just stuck in the fixing hole, and then the upper cover and the base are connected; therefore, the upper cover and the base are not detachably connected. Once the two are detached, the upper cover and the base are unusable. resulting in waste of resources

[0007] 4. The thickness of the conductor and the conductive clip is inconsistent, so the material consumption is more, the processing is difficult, and the cost is high
