Description
Technical Field
The utility model relates to a used fuse among protection circuit such as electric power, new forms of energy electric motor car especially indicates pipy fuse.
Background
Fuses are common components in circuit protection. Generally consists of a tubular housing, a melt, an inner cap, an outer cap, pin terminals, and an arc-extinguishing medium. The melt is contained in a shell, and arc extinguishing medium is filled in the shell. Outer cap and pin terminal are manufactured alone to this type of fuse, and pin terminal generally adopts the riveting to be connected to outer cap on, and this structure easily leads to pin terminal and the contact of outer cap not enough, makes the accessible electric current reduce to the electricity performance of fuse has been reduced. In the processing process of the fuse, the processing process of riveting and welding the outer cap is complicated, the good conductivity can be ensured only by firmly welding, welding is usually carried out by consuming a large amount of lead-containing tin-based melting point solder, and the cost reduction and the environmental pollution protection are not facilitated; if the direct large-current spot welding or the combustible gas welding connection is adopted, the outer cap is softened and deformed due to high-temperature annealing, and poor conductivity is easily caused when the outer cap is not tightly pressed with the inner cap. And this type of fuse structure is owing to weld on the PCB board, generally through wave-soldering/reflow soldering welding process, and this type of welding requires the product can tolerate about 260 ℃ 10s time, just needs high temperature tin to weld for satisfying this requirement, and high temperature tin is unfavorable for the welding and has the welding strength risk because the higher mobility of melting point is relatively poor.
Disclosure of Invention
The utility model aims to solve the technical problem that a fuse is provided adopts pin terminal and outer cap integration shaping structure, has simplified fuse preparation process, has improved the reliability of fuse structure.
In order to solve the technical problem, the utility model provides a technical scheme is a fuse is used in welding of integration double pin PCB board, including the casing, its characterized in that is in the both ends of casing are provided with outer cap respectively the brim of a hat end integrated into one piece of outer cap has the pin terminal.
Two pins are arranged at the free end part of the pin terminal at intervals.
The pin terminal is in a bending state.
The utility model discloses a fuse, outer cap and pin terminal integrated into one piece, it has saved traditional pin terminal and outer cap riveting, welded complicated process, simple structure, and the product reliability is higher. The structure has no problems of wave soldering failure and high-melting-point solder brazing, and is simple to combine and convenient for automatic production of fuses.

Fig. 2 is a schematic view of the three-dimensional structure of the fuse of the present invention.
Detailed Description
With respect to the above technical solutions, preferred embodiments are described in detail with reference to the drawings. See fig. 1-2, wherein.
The tubular casing 1 has a hollow opening structure, and may be made of ceramic, glass fiber, melamine, or other materials. The fuse-element is arranged in the shell 1, the inner cap and the outer cap 2 are sequentially arranged at the two ends of the shell, the pin terminal 3 is arranged on the outer cap 2, and the two pins 31 are arranged at the free end of the pin terminal at intervals. The pin terminal is integrally formed at the brim end of the outer cap and is bent into a required shape. Integrally molding an outer cap and a pin terminal: generally, a sheet metal base material is adopted, then a required size and a required structure are punched from a metal sheet through a punching technology, and then the pin terminal is bent through a bending machine to form a required integrated structure of the outer cap and the pin terminal. When the assembly is carried out, the outer cap is riveted at the end part of the shell in an interference manner.
The utility model discloses a fuse, outer cap and pin terminal integrated into one piece, it has saved traditional pin terminal and outer cap riveting, welded complicated process, simple structure, and the product reliability is higher. The structure has no problems of wave soldering failure and high-melting-point solder brazing, and is simple to combine and convenient for automatic production of fuses.
