At present, China's automobile industry has entered a stage of high-quality development. Six major automobile industry clusters have been formed domestically, namely in the Yangtze River Delta, the Pearl River Delta, the Beijing-Tianjin-Hebei region, the Central China region, the Chengdu-Chongqing Western region, and the Northeast region. In order to accelerate the integration and innovation of the automotive industry supply chain, and to contribute to the construction of a manufacturing powerhouse, under the active promotion of the Guangdong Provincial Department of Industry and Information Technology, the "2023 Guangzhou International Integration and Innovation Exhibition for the New Energy Automobile Industry" with the theme of "crossing boundaries, deep integration, and reshaping the automotive industry chain" has emerged." XC Electronics(Shenzhen)Corp.,LTD participated in this exhibition as an outstanding supplier of fuses in the new energy industry.
Today, the Topband visited our factory for the annual factory audit. The company is a global leading provider of intelligent control technology, we have established a partnership with them for more than 15 years."
The fuses commonly used in PCB boards of small household appliances use self recovery fuses to protect the circuit. The selection of self recovery fuses in small household appliances can be divided into the following steps: Firstly, determine the working voltage of the self recovery fuse; 2. Based on the actual average operation of different products, determine whether the self recovery fuse is the inactive current; 3. The maximum current ratio, temperature, and other parameters of household small appliances in actual work, as well as the time required for self recovery fuse self correction (self recovery fuse action current amplification or reduction); 4. Revise it to an actual experiment and ensure that there is no false protection work, but it is necessary to self recover the fuse parameters within the specified time and protect the motor from stalling. The change in the thermistor of a small motor is an easy choice, but after repeated experiments, the thermal resistance of
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
