The operation mode and temperature requirements of automobile fuse holder

 

Automobile fuse holders are generally used in electric vehicles such as automobiles, and have a wide range of uses. So how is the car fuse holder fixed? What is its temperature requirement? Let's follow the PCB board fuse holder manufacturer AMPFORT to find out.

 

1. Fixing the car fuse holder
Automotive fuse holders are also divided into PCB boards and wired types. The PCB board is used less, so the connection type, the connection type is similar to the above-mentioned lead fuse holder, and the installation is also very simple. The car fuse holder can be divided into three sizes, large, medium and small. Regular use is medium, and they are installed in a very similar way.

After the panel installation is fixed, we can purchase the fuse holder according to the size of the hole. The panel installation fuse holder is different from other fuse holders. The panel installation requires screws and threads to fix it, and also requires welding terminals. The fuse can be installed after the fuse holder is secured.

Generally, the head of the panel-mounted fuse holder can be roughly divided into spirals, and some of them need to be unscrewed with a screwdriver to install the fuse. This is generally divided into a prefix fuse holder and a cross-head fuse holder. These two fuse holders are widely used.

The car fuse and the daily household fuse of the fuse are the same, and it also protects the normal operation of the car's electrical appliances and prevents the car from igniting spontaneously. The fuses on the car are basically blade fuses, which are quite convenient to use and replace.

However, you should also pay attention to the current size of the car fuse, which cannot be replaced casually. Take the more commonly used blade fuse, it adopts a plug-in structure, the shell is made of plastic material, and the color is relatively rich. The thing to watch out for is its color. Different colors correspond to different amps.

Second, the use of automotive current fuse holder and its temperature requirements
The car fuse holder mainly refers to the seat installed in the car fuse when it is used. Its products can be effectively divided into panel-mounted car fuse holders, lead-type car fuse holders, and car fuse clips. The panel mounted car fuse holder is mostly used in car electrical appliances, such as car power amplifier, car speaker, car DVD, etc.

In the process of using the car fuse holder, its fuse can accept the overload that must be planned when the current fluctuates from its power supply or its external disturbance to a certain extent, and there is a relatively large overload current in the circuit of the car fuse holder. , its fuse should block its overload current for a fixed period of time.

The car fuse holder can maintain the safety of other electronic components in the circuit to a certain extent, when a short circuit occurs in the circuit and its large current occurs. Their fuses can safely block their circuits, which will protect them from damage due to overcurrent.

The fuse in the car fuse holder can be used under the voltage of the rated voltage of the same or small, but generally cannot be used in the circuit of the circuit voltage and the rated voltage of the fuse, the voltage drop in the equipment, the fuse In the pass rated application flow.

The balance of the fuse holder, that is, the voltage measured at both ends when the temperature is stable, and the voltage drop across the fuse will have a certain impact on the circuit to a certain extent. Therefore, there are clear rules for voltage drop in the rules. There are no requirements in the rules. The overload current in the car fuse holder mainly refers to the current flowing in the circuit during normal operation. If the overload current cannot be blocked, it may cause damage to other electronic components in the circuit.

The above is the introduction of the operation mode and temperature requirements of the car fuse holder. If you want to know more about the PCB board fuse holder, please contact us-AMPFORT.
