This article is mainly about the automobile fuse holder related introduction, and focuses on the automobile fuse holder structure, classification and function for a detailed description.

Car fuse holder

Automobile fuse seat refers to the seat that installs automobile fuse, automobile fuse seat can be divided into: the panel installs automobile fuse seat;Lead type automobile fuse holder;Car fuse holder.The panel installs the automobile fuse seat to be used for the automobile electric appliance, such as the automobile power amplifier, the automobile sound box, the automobile DVD and so on.

Function and construction of automobile fuse holder

In the process of using the automobile fuse holder, the fuse can withstand the overload in a certain range due to the power supply or external interference caused by the gash current fluctuation. When a relatively large overload current occurs in the circuit of the automobile fuse holder, the fuse should cut off the overload current within a fixed time.

Automobile fuse seat can protect the safety of other electronic parts in the circuit to a certain extent. When the circuit has a short circuit and a large current, the fuse can safely cut off the circuit, so as to prevent them from being damaged by excessive current.

The rated current in the fuse seat is the valid nominal working current of the fuse. The rated current value is usually 100mA, 160mA, 200mA, 315mA, 400mA, 500mA, 630mA, 800mA, 1A, 1.6a, 2A, 2.5a, 3.15a, 4A, 5A, 6.3a, etc.

The fuse in the automobile fuse seat can be used at the voltage equal to or less than its rated voltage, but generally cannot be used in the circuit voltage greater than the rated voltage of the fuse, the voltage drop in the equipment, the rated current on the fuse.

The thermal balance of automobile fuse seat is the voltage measured at both ends and the voltage drop at both ends of the fuse will have a certain effect on the circuit to a certain extent when the temperature is stabilized. Therefore, there is no requirement for the explicit provision of voltage drop in the regulation.

The overload current in the car fuse seat mainly refers to the current flowing through the circuit which is higher than the normal operation. If the overload current cannot be cut off, it may damage other electronic parts in the circuit.

Classification of car fuse seat

Lead type automobile fuse seat is often used in automobile wiring harness.Auto fuse clip is used for installing auto fuse on the circuit board, which is easy to install and convenient to disassemble. According to the classification of installing fuse, it can be divided into safety tube box and safety piece box.

If auto fuse blocks according to the fuse size to distinguish, fuse box can be divided into large, medium, fuse box, small fuse box, according to the material points, fuse box can be divided into plastic, bakelite, fuse box, according to the environmental protection, can be divided into environmental protection, fuse box, the environmental protection fuse box, according to the installation points: can be divided into lead fuse box and circuit board type fuse box, instrument panel installation fuse box, etc.

Automobile fuse seat for the current sensitive components, its function is to make a judgment on the overcurrent, the flow is not allowed when the fault overcurrent fuse should play a protective function;And for such non-fault overcurrent as instantaneous pulse, the fuse should be able to withstand enough times to ensure the normal use of the whole machine.

Current generally can’t more than normal when using the pulse boot, electricity will not more than 10 times, auto fuse holder should never action, and in case of abnormal fusing must be have a problem, if not timely find out the cause of the abnormal fusing, only by replacing the fuse, or simply increase the fuse capacity is not reassuring.

According to the classification of the fuse installation, can be divided into insurance tube box and insurance box according to fuse size, fuse box can be divided into large, medium, fuse box, small fuse box to press material cent, fuse box can be divided into plastic, bakelite fuse box according to the environmental protection, can be divided into environmental protection, fuse box, the environmental protection fuse box according to the installation points: can be divided into lead fuse box and circuit board type fuse box, instrument panel, install the fuse box

What is the difference between a car fuse and a car fuse seat

Automobile fuse is a current fuse, when the circuit current more than 2 times the rated current of the fuse will fuse in a few seconds, play the role of circuit protection.It is often used to protect the passing current of automobile power, and also to protect the passing current of industrial equipment.There are many electrical devices connected by different color wires in the automobile circuit, among which the fuse should be the most important.Fuse is a common name, the national standard called the fuse.The function of a fuse is to protect circuits and electrical equipment.
