Problems solved by technology

[0003] The manufacturing process of the existing fuse is material preparation, extrusion molding, double-sided film coating and double-sided nickel plating, punching into products, irradiation, sorting and packaging for shipment. The inventor found that the existing fuse is produced according to the law of traditional technology. The resistors have a large resistance tolerance range, and products with a 1.5-4mΩ variation range will come out mixed together. Generally, the customer's finished product requires a resistance value within 2mΩ, which results in the need for sorting after irradiation. Producers need Purchasing a sorting machine is not only costly, but also time-consuming

Abstract

The present invention discloses a sorting tool of resettable ring fuses manufactured by PPTC. The sorting tool comprises a body, discharge tubes and material collection boxes, the body is installed ona punching machine, discharge ports are uniformly arranged on the body, the numbers of the discharge tubes, the discharge ports and the material collection boxes are consistent, one end of each discharge tube communicates with one discharge port, the other end of each discharge tube communicates with one material collection box, and one discharge port, one discharge tube and one material collection box form one sorting channel. The sorting tool is simple in structure, reasonable in design and good in use effect, can automatically sort the fuses by installing the product on the punching machine and achieve control of the discharge tubes, is small in size, convenient to use and easy to promote and use, allow users not to purchase a sorter to reduce the cost, omits the sorting process and meets the use demands of people.

Description

technical field [0001] The invention relates to the field of fuse preparation, in particular to a sorting tool for recoverable ring fuses made by PPTC. Background technique [0002] With the improvement of people's living standards and the increase of people's economic income, more and more people have their own houses, and people will install various electrical appliances in their houses. With the increase of electrical appliances, people will The circuit performs more protection, and the fuse is a commonly used circuit protection device. Fuses are also called current fuses. The IEC127 standard defines them as "fuse links". The fuse is mainly used for overload protection. If the fuse is correctly placed in the circuit, the fuse will fuse itself to cut off the current when the current abnormally rises to a certain height and heat, thus protecting the safe operation of the circuit. [0003] The manufacturing process of the existing fuse is to prepare materials, extrusion mo...
