Introduction to fuse holder
In this paper, I mainly explain the content of the fuse seat for you, with the development of technology, the application of the fuse seat in society will be more and more extensive, so the prospect of the fuse seat is very good.The following content mainly analyzes the improved structure of fuse holder and the classification of fuse holder.
Fuse seat refers to the seat used to install the fuse, the fuse seat can be divided into: panel installation fuse seat, PCB installation fuse seat, lead fuse seat and car fuse seat;
Panel installation fuse seat (more used for electrical equipment, such as power amplifier, DVD, speaker, massage chair and other electrical equipment);Lead type fuse holder (used for connection of small home 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).Automobile fuse seat can be divided into lead type automobile fuse seat (multi-purpose automobile and industrial machinery wiring harness);
The panel is equipped with a car fuse holder (mainly used for car electrical appliances, such as car amplifier, car refrigerator, car DVD, etc.) and a car fuse holder.
Fuse holder has the requirements of resistance to current, voltage, and fire rating, etc., generally need to pass UL CSA VDE ROHS and other safety regulations and the European Union certification.
Improved structure of fuse holder
Improved structure of fuse holder, especially a fuse holder that shows the condition of the fuse and does not require replacement of the self-compound fuse.
It consists of: a first channel body with several holes connected to each other respectively;A number of secondary channels, each with one screw hole and one socket connected to each other, each with one connecting screw;Several self-compound fuses are electrically connected between the first channel body and each second channel body;
A base for the first and second channel bodies is provided on the top side solid;An upper cover covering the base;And a circuit board fixed on the upper cover and equipped with several luminous components, which forms an electrical connection with the first channel body and each second channel body.
Classification of fuse holder
According to the classification of fuse installation, it can be divided into safety tube holder and safety plate holder.
According to the size of the fuse, can be divided into large fuse seat, medium fuse seat, small fuse seat;
According to the material, can be divided into plastic fuse seat, bakelite fuse seat;
According to the environmental protection points, can be divided into environmental protection fuse seat, non – environmental protection fuse seat;
According to the installation method: can be divided into lead fuse box and circuit plate type fuse seat, instrument panel installation fuse seat;
The commonly used models are (for the size of applicable fuse tube) : 5×20mm fuse holder, 6×30mm fuse holder;
Car fuse seat (suitable for insert) : small insert fuse seat, medium insert fuse seat, large insert fuse seat.
Above is commonly used, the choice of fuse seat should see him suit, basically see installation size, suit fuse tube size, shape and its performance.
In a word, in fact, there is an important fuse in the structure of the fuse seat, and according to the above several aspects of the fuse seat, I believe that you have some knowledge of the fuse seat, such as you have other technical questions, you can continue to pay attention to this site.
