The wiring methods of fuse holders mainly include plug-in wiring and threaded wiring. Plug and play wiring refers to inserting wires into the socket inside the fuse holder and clamping them with spring plates to achieve wiring; Screw type wiring is the process of threading wires into threaded holes in the fuse holder and connecting them through the frictional force of the threads. Below, we will introduce these two wiring methods separately. Plug and drop wiring is a common fuse holder wiring method. It has the advantages of simple wiring and convenient installation, and is suitable for application scenarios with smaller wire sizes. The spring plate of plug-in wiring needs to ensure sufficient force and reliability when clamping the wire. According to statistics, fuse holders with plug-in connections have a slightly higher electrical failure rate than fuse holders with threaded connections, but their prices are cheaper. The plug-in fuse holder is suitable for low voltage and low c
The structure of a fuse holder mainly consists of the fuse holder body, base, terminals, pins, etc. Below, we will introduce these structures separately. The fuse holder body is the main part of the fuse holder, which is usually made of insulating material and can fix the fuse, pins, and terminals. The shape, size, structure, and material selection of the fuse holder body will have a significant impact on the performance and reliability of the fuse holder. The fuse holder body is usually divided into various shapes such as cylindrical, square, rectangular, etc., and different shapes and sizes can be selected according to different application scenarios. In addition, the insulation material of the fuse holder body should have good insulation performance, heat resistance, and chemical corrosion resistance to ensure the safety and reliability of the fuse holder. The base of a fuse holder is usually made of metal material, used to fix the fuse holder body, pins, and terminals. The ma
According to different usage scenarios and characteristics, fuses can be divided into the following types: 1. Glass tube fuse Glass tube fuse is the most common type of fuse, usually composed of a glass tube and two end joints, with a metal wire inside. When the current exceeds the rated value, the metal wire will melt and cut off the circuit. This type of fuse is usually suitable for low voltage, low current circuits. 2. Hot melt fuse Hot melt fuse is also a commonly used fuse, which is made of fusing alloy inside. When the current exceeds the rated value, the fusing alloy will melt and break, cutting off the circuit. This type of fuse is usually suitable for high current, high temperature circuits. 3. High voltage fuse High voltage fuse is a type of fuse specifically used in high voltage circuits, with a fuse made of conductors inside. When the current exceeds the rated value, the fuse will melt and cut off the circuit.
A. Classified by temperature variation characteristics - positive temperature coefficient (PTC), negative positive temperature coefficient thermistors. B. Classified by sensitivity to temperature changes - high sensitivity type (mutation type), low sensitivity type (slow change type) thermistors. C. Classified by heating method - direct heating thermistors, side heating thermistors. D. Classified by structure and shape - various types of thermistors such as circular (sheet), cylindrical (cylindrical), circular (gasket), etc. The most common names for thermistors are PTC thermistors and NTC thermistors. So what is the difference between these two types of thermistors? 1、 PTC thermistor PTC thermistor structure - made from materials such as barium titanate (BaTiO3), strontium (Sr), zirconium (Zr), etc. PTC thermistor characteristics - the resistance value is directly proportional to the temperature change, that is, the resistance value increases as the temperature increases. A
Easy to install: The WH self resetting overcurrent protector has no polarity and can be connected in series to the circuit that needs protection. It is not only widely used, but also safe and reliable. Reuse: After cutting off the power and troubleshooting, it automatically returns to normal state without the need for manual replacement and can be reused. Improving quality: It can improve the quality of customer products, greatly reduce the natural damage rate of finished products, and greatly extend the service life of products. No reconnection: Under fault conditions, the faulty circuit will not be reconnected (other protective circuits, bimetallic plates, etc. will be repeatedly reconnected to expand the fault range). Add highlights: Due to the addition of high-tech elements, it can add new shining points to customer products, making vulnerable circuits no longer fragile. Reduce costs: Reduce the number of components, PCB area, and damage during operation compared to
The fuse is broken, can you replace it yourself? There are two types of color TV fuses, severe and mild. Slight, refers to a slight blown fuse, usually replaced with a new one. Severe refers to the metal inside the fuse being burned to pieces or blackened out. If you replace it with a good fuse at this time, you will see the fuse light up as soon as you turn it on and immediately burn it out. As soon as the machine is turned on, the fuse will burn out. Therefore, the voltage measurement method with a universal meter cannot be used for maintenance, and only the resistance measurement method with a universal meter can be used for maintenance. The cause of severe fuse burning is often due to a short circuit or variable value in one or at most two parts of the circuit. The faulty parts are in the circuit after the fuse, mostly in demagnetization circuits, 220 rectifier circuits, and switching tubes. Based on the above knowledge of color TV fuses, the repair methods for color TV fuses
