When you see the PIN needle, do you think that it is the same as the general needle, what does it do? Understand the following points and you will understand the role of the PIN needle.
1. Analysis of PIN needle material
The PIN needle material is "tungsten carbide" raw material, that is, cemented carbide: cemented carbide has high hardness, strength, wear resistance and corrosion resistance, known as "industrial teeth", used to manufacture cutting tools, cutters, cobalt tools and wear-resistant parts, widely used in military industry, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, cemented carbide market demand continues to increase. In addition, the future technology weapons and equipment manufacturing, the progress of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for high-tech and high-quality and stable cemented carbide products.
2. PIN needle ceramic ferrule
It is an important component of optical communication network and a product of Ceramic Injection Molding (CIM). Optical fiber connector is an indispensable passive device in the optical fiber communication system, which is mainly used to realize the precise docking of the two end faces between equipment, equipment and instruments, equipment and optical fiber, and optical fiber and optical fiber in the system, so that the optical energy output of the transmitting optical fiber can be coupled to the receiving optical fiber to the limit. Most fiber optic connectors consist of three parts: two mating plugs (ferrules) and a coupling sleeve. Two ferrules are fitted into two fiber tips; The coupling sleeve plays the role of alignment, and the sleeve is mostly equipped with metal or non-metal flange to facilitate the installation and fixing of the connector.
3. PIN needle technology
Ferrules for fiber optic connectors have been mass-produced using ceramic injection molding technology, and the ceramic material used is zirconia. Among various metal oxide ceramic materials, zirconia has good high-temperature thermal stability and thermal insulation performance, and is suitable for ceramic coating and high-temperature refractory products; Zirconia as the main raw material of zirconia based ceramic pigment is an important component of glaze; The thermal conductivity of zirconia is low among common ceramic materials, and the coefficient of thermal expansion is close to that of metal materials, making it an important structural ceramic material. the crystal structure, making it an important electronic material; Zirconia has the characteristics of phase transformation toughening, which has become the darling of plastic ceramic materials; The good mechanical and thermophysical properties enable it to become a reinforcing phase with excellent properties in metal matrix composites. Therefore, the ceramic ferrule material of the optical fiber connector adopts yttrium-stabilized nano-zirconia powder raw material (Y-PSZ).
4. PIN needle requirements
As an optical communication technology accessory, the contact core PIN pin used in the ceramic powder injection molding mold is a high-precision product, and the tolerance requirement is ±0.001-±0.0005. In the operation of ceramic ferrule production by ceramic powder injection molding, the core needle is required to be acid-resistant, corrosion-resistant, high-temperature resistant and other high-demand environments, and for industrial teeth such as cemented carbide, it is competent for such high-temperature corrosive environment operations. In the process of producing nano zirconia in ceramic powder injection molding molds, the cemented carbide core needle adapts to its high-temperature working environment, and the long-term and long-lasting operation makes the large-scale and mass production of ceramic ferrule core a direct embodiment.
According to the different models of core pins with different equipment, ceramic ferrule pins and PIN pins can be customized according to the requirements, and the ferrule pins can be customized and processed according to the supporting requirements of ceramic powder injection molding molds. Due to the precision requirements of ceramic ferrule core pins, they are usually customized according to the requirements of the drawings.
5. The role of PIN needle
Knowing this, I believe it is not difficult to solve the role of the PIN pin in the connector. Generally, the PIN pin is mainly used in the connector, and the PIN pin is used in the connector to complete the conduction (transmission) of electricity (signal).
Jinchuan Electric has a research institute, specially recruited engineers for PIN pins and four guidelines, and the company has 100 sets of equipment, which has been recognized and trusted by well-known connector manufacturers at home and abroad. The company's official website www.jc-pin.com
