1. Instructions for use of the fuse holder
Automobile fuse holders are used to install automobile fuses. The categories of automobile fuse holders can be divided into: panel mounted automobile fuse holders; lead type automobile fuse holders; automobile fuse clips. Panel mount car fuse holders are mostly used in car electrical appliances, such as car power amplifiers, car speakers, car DVDs, etc. Lead type automotive fuse holders are mostly used in automotive wiring harnesses. The car fuse clip is used to install the car fuse on the circuit board, which is easy to install and disassemble. And because of the different specifications of car fuses, the types of seats are also different. According to the classification of the installation fuse, it can be divided into insert type and tubular type. According to the size of the fuse, it can be divided into large fuse box, medium fuse box and small fuse box. According to the material, it can be divided into plastic car fuse holders, bakelite car fuse holders, and PVC car fuse holders. According to environmental protection, it can be divided into environmentally friendly fuse holders, non-environmentally friendly fuse holders, and according to installation methods: it can be divided into lead-type automotive fuse holders and circuit board fuse holders, and fuse holders installed on instrument panels. Among them, the lead type automobile fuse holder also has the classification of wire rods, and the classification of wire rods is generally in accordance with the national standard 1015, 1007 series of electronic wires as the lead wires.
2. What is the role of the fuse
When a circuit breaks down, the current will continue to rise, which may cause damage to the circuit and affect the use of other electrical appliances. In severe cases, a fire will occur. If a fuse is installed, when the current is abnormal, it will reach a certain height. It will automatically blow the fuse, cut off the entire circuit, and play a protective role.
3. Working principle of fuse
The temperature of the fuse due to the heat converted by the current rises. When the load is overloaded by the normal working current, the heat generated by the current and the heat emitted by the surrounding environment by radiation/convection/conduction are gradually balanced; if the heat dissipation speed cannot keep up with the heat generation speed, then The heat will gradually accumulate on the melt to make the temperature of the melt rise. Once the temperature reaches or exceeds the melting point of the melt material, it will be liquefied or vaporized, thereby disconnecting the current and protecting the circuit and personal safety. .
