Construction and Type Affecting Nomex Braided Sleeve

Nomex Braided Sleeve, one of the basic components of semiconductors, has the function of current amplification and is the core component of electronic circuits. The braided network tube is made of two PN junctions that are very close to each other on a semiconductor substrate. The two PN junctions divide the positive semiconductor into three parts. The middle part is the base area, and the two sides are the emission area and the collector area. And NPN, the corresponding electrodes are drawn from the three regions, respectively, the base b emitter e and the collector c The PN junction between the emitter region and the base region is called the emitter junction, and the PN junction between the collector region and the base region The junction is called the collector. The base area is very thin, while the emission area is thicker and the impurity concentration is high. The PNP type braided network tube emission area "emits" holes, and its moving direction is consistent with the current direction, so the emitter arrow points inward; the NPN type braided network tube emission area "emits" holes. "Free electrons move in the opposite direction to the current, so the emitter arrow points outward. Emitter arrow pointing outward. The direction of the emitter arrow is also the conduction direction of the PN junction under forward voltage.

The packaging forms of commonly used braided network pipes include metal packaging and plastic packaging. The arrangement of the pins has certain rules. The position of the bottom view is placed so that the three pins form the vertices of an isosceles triangle. From left to right, they are: ebc For small and medium power plastic braided network tubes, make the plane face itself according to the figure, and place the three pins facing downwards, then it is ebc from left to right. At present, there are many types of Nomex Braided Sleeve in China, and the arrangement of the pins It is not the same. For braided network tubes with uncertain pin arrangement in use, it is necessary to measure to determine the correct position of each pin, or to find the transistor manual to clarify the characteristics of the braided network tube and the corresponding technical parameters and information. Current amplification effect of Nomex Braided Sleeve Nomex Braided Sleeve has current amplification effect, the essence of which is that the braided mesh tube can control a large change in the collector current with a small change in the base current.
The braided mesh tube is woven with environmentally friendly PET and other materials, and has good wear resistance, expandability, smoothness, flame retardancy, and breathable and heat dissipation properties. The products are widely used in the maintenance and beautification of computer power lines, audio and video lines, lighting, air conditioners, refrigerators, washing machines and other household appliances, as well as optical cables, motorcycles, automobiles, airplanes and other lines, and can be woven with single or three wires according to customer requirements. Braided mesh tubes in different widths, colors and patterns.
Common reasons for the failure of general braided network pipes:
1. The first is the problem of the material itself. If the PET yarn produced from recycled materials is generally not resistant to high temperature, and the weaved product is also uneven and lacks luster.
2. In the production process, the yarn was not paid attention to, resulting in one or two yarns not being aligned neatly in the middle, and yarn skipping occurred during knitting.
