What is the cause of the fever of the fuse holder? What are the characteristics of the electrical function? How can fuse holder terminals be used to prolong life? Today, the fuse holder manufacturer analyzes for the big family.

Characteristics of heating speed and electrical function of fuse holder

In the course of using the fuse holder, when the current flows through the conductor, the conductor will be heated because there is a certain resistance between the conductors，When the fuse of the fuse seat is electrified, the temperature of the melt will rise because of the heat of the current transformation. In the process of loading the normal operating current or the allowable overload current, the heat generated by the current and the radiation from the shell and the surrounding environment can gradually reach balance.

If the loose holding speed of the fuse holder can not keep up with the starting speed, these holding quantities will gradually accumulate on the melt, causing the melt temperature to rise, and when the daily temperature reaches and exceeds the melting point of the melt material, it will liquefy or vaporize it, and then disconnect the current. It has the effect of safety maintenance to the circuit and the person.

The electrical function of the fuse holder, when in use, its fuses are connected in series in the electronic circuit, which generally requires its electricity to be small. When the circuit is working normally, it only dries a wire and can lead the circuit safely for a long time. When the current is shaken due to power supply or external disturbance, it should also be able to withstand a certain range of overload.

In the fuse seat, when there is a relatively large overload current in the circuit, the split fuse will act and disconnect the current to maintain the safety of the circuit. Therefore, there will be two very important working parameters in its operation, namely rated voltage and rated current. In the process of use, the fuse holder needs to effectively select the corresponding fuse seat according to the current and voltage of its circuit.

The method of prolonging the life of fuse holder terminal

There are many kinds of automobile fuse seat, one of which is commonly used by the combination of hardware terminals and plastic, it is generally welded on the PCB, with convenient welding, simple operation, so that the user to sit hot, widely used white beans good, then since it is commonly used by a sub-component, how should we protect its contact terminal.

During the later use of the automobile fuse seat, the service life of the equipment is shortened due to the erosion of various factors, and the electronic components of the fuse seat are composed of hardware and plastic. therefore, metal erosion is mainly caused by poor electrical conductivity or short circuit caused by oxidation, the main position is at the connection between the two and so on.

General automobile fuse seat hardware contact terminals are mainly affected by corrosion of metal and metal electroplating and composition. Among them, the use of ordinary metal as the terminal makes the erosion more serious, and the service life will be greatly reduced. Secondly, with the increase of circuit current, the general terminal will be heated or burnt out, and with the increase of temperature, the corrosion rate will increase by 1 to 3 times.

At the same time, for the exchange medium with fast dry flow rate, under the use of fuse holder, the flow rate will greatly affect the speed of corrosion. Therefore, the root cause of thoroughly solving the corrosion problem of automobile fuse base terminals is the alternative material. We suggest that the safety seat terminals are generally made of easily conductive materials, resistant to strong acid and alkali, so choose high-quality brass fuse base terminals and give surface treatment, which can easily resist all kinds of corrosion, reduce the damage of electronic components, and prolong the service life normally.

In addition, dustproof protection in the later stage is also essential, especially in the south, where it is humid and dry in spring and summer, any damp terminals are very likely to cause oxidation and corrosion, which can also prolong the service life of automobile fuse seats.

The above is the introduction of the heating speed of the fuse holder and the method of prolonging the life of the terminal. If you want to know more about the fuse holder, please feel free to contact us.
