How to Extend the Life of Fuse Holder Terminals
There are many kinds of car fuse holders, one of which is commonly used is a combination of hardware terminals and plastics, which is generally welded on the PCB, which is convenient for welding, simple to operate, and easy to use. So since it is a commonly used sub-component, how should we protect its contact terminals? W3 is extending its lifespan.
In the later use of the automobile fuse holder, the service life of the equipment is shortened due to the erosion of various factors. The electronic components of the fuse holder are composed of hardware and plastic parts. Therefore, the metal erosion mainly occurs due to poor electrical conductivity or short circuit caused by oxidation. is at the junction of the two.
Generally, the metal contact terminal of automobile fuse holder is mainly affected by corrosion, which is mainly composed of metal and metal electroplating layer and composition. Among them, the use of ordinary metal as the terminal will make the erosion more severe, and the service life will be greatly reduced. Secondly, with the increase of the circuit current, the general terminal will generate heat or burn out. With the increase of temperature, the corrosion rate will also increase by 1~3 times.
At the same time, for the exchange medium with fast dry flow rate, when the fuse holder is used, the flow rate will also greatly affect the corrosion rate. Therefore, the root cause of completely solving the corrosion problem of automobile fuse holder terminals is to substitute materials. We recommend that the fuse holder terminals are generally made of conductive materials, which are resistant to strong acid and alkali. Therefore, high-quality brass fuse holder terminals are selected and surface treated, which can easily resist various corrosion, reduce damage to electronic components, and extend the service cycle normally.
In addition, dust-proof protection is also essential in the later period, especially in the south, where it is humid, especially in the spring and summer.
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 contact us.
