This paper is mainly about the related introduction of the automobile fuse seat, and focuses on the size of the automobile fuse seat and the size of 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.
A fuse holder is a seat used to install a fuse,
Fuse block can be divided into: panel installation fuse block, PCB installation fuse block, lead type fuse block and automobile fuse block;
Fuses are installed on the panel (mostly used for electrical equipment, such as power amplifier, DVD, speaker, massage chair and other electrical equipment);
Lead type fuse holder (mostly used for connection of small household appliances and wiring harness of industrial machinery);
PCB fuse holder (mostly used on small home appliance control board) and fuse holder (mostly used on small home appliance control board).
Automotive fuse seat can be divided into lead type automotive fuse seat (multi-purpose automotive and industrial machinery wiring harness);
The panel installs the automobile fuse seat (mostly USES in the automobile electric appliance, such as the automobile power amplifier, the automobile refrigerator, the automobile DVD and so on) and the automobile fuse clip.
Fuse holders are required to withstand current, voltage, and fire rating, and are generally required to pass UL CSA VDE ROHS safety regulations and eu certification.
According to the classification that installs fuse, can divide into safe tube seat and safe piece seat
According to the size of the fuse, it can be divided into large fuse holder, medium fuse holder, small fuse holder
By material cent, can divide into plastic fuse holder, bakelite fuse holder
Press environmental protection cent, can divide into environmental protection fuse block, blame environmental protection fuse block
According to the installation method: can be divided into lead type fuse box and circuit board type fuse seat, instrument panel installation fuse seat
The commonly used models are (for the size of fuse tube) : 5×20mm fuse holder, 6×30mm fuse holder;
Automobile fuse holder (suitable for insert type) : small insert fuse holder, medium insert fuse holder, large insert fuse holder.
Above is commonly used, the choice of fuse seat should see oneself suit, basically see installation size, suit fuse tube size, shape and its performance.
Improved structure of fuse holder
An improved construction of a fuse holder, especially one having a fuse holder that shows the condition of the fuse and does not require the replacement of its self-compound fuse.It includes:
The first guide body is provided with a number of connected screw holes and a first guide body, each hole is threaded into a connecting screw;A second guide body with a screw hole and a socket connected to each other, each screw hole is threaded into a connecting screw;
A number of self-compound fuses connected between the first conducting body and each second conducting body by electrical connection;The top side is fixedly provided with the base of the first and second guide body;
An upper cover covering the base;And a circuit board fixedly arranged on the upper cover and arranged with several light emitting assemblies, which are electrically connected with the first conducting body and each second conducting body.
What is the size of the conventional automobile fuse seat
Automobile fuses can be produced from 1A, 2A, 3A, 4A, 5a-40a in different colors.
You probably know that a car fuse comes in several colors, so here are some of them.
Car fuse different current is divided into different colors, fuse thickness is not the same.
Automobile fuse has two important working parameters, one is the rated current;One is the rated voltage, when using according to the circuit current and voltage to choose the corresponding fuse.
In terms of structure, the plug type design is used for the general automobile fuse. The automobile fuse has an engineering plastic shell, which is covered with a zinc melt structure. The metal melt is connected with the pin.
Test method of fuse holder
Fuse safety specification. Most microfuses are certified as UL248 or IEC127. This specification specifies that the following items are not fusible when energized for 1 hour at rated current.
According to the rated current electricity when the temperature rise of the 75 ℃ Δ. In cases with 2 times rated current fuse within 1 minute. Add the interrupting capacity rating, not fly continuously produce arc or spark. Does we may follow this way for product testing added:
1. Temperature and voltage test: apply voltage and current to the fuse with the power supply.Fixed voltage of 220 v, and starting from the 2 amp supply current, increase every 4 to 5 minutes intervals (2 to 10 amp rated current electricity when the temperature rise of the Δ 75 ℃.
2. Fuse time test: the stopwatch is used to record and observe the rated current of 2 times and its residual current value, and measure the time required for the fuse. Under the condition of the rated current of 2 times, the fuse is cut off within 1 minute, and the situation before and after the fuse is taken.
3. Fuse sample test, whether it is 2 times the rated current or other supply current, three fuse samples of the same specification are tested to average the fusing time.
