Pinneedle manufacturers said the use of the product points?
Pin pin is a key component of industrial connectors. In fact, its appearance directly determines the quality of products. Reasonable design is very important. Many industrial socket and plug suppliers have been committed to the research and development of this technology?

The pin pin manufacturer said that its parameters and material standards are mainly reflected in its contact resistance, and the additional resistance of the contact area of the two metal conductors is called the contact resistance. Under the microscope, contact occurs only at certain points of contact. The current wire contracts on the contact surface, producing a contraction resistance Rs. In addition, the contact surface exposed to the air rapidly forms a thin film such as an oxide film, as well as a sheet resistance Rb. Then there is its needle pressure F, which actually acts on the two needles, causing them to touch. Increasing the pin pressure will reduce Rj, because the increased pressure will make the contact area larger. In addition, the increased pressure will also destroy the film, thereby reducing Rb. Temperature changes are also known before use. The pin pin manufacturer said that after a long time of power-on, the pin temperature will rise. This change is not only related to the current, material and size of the PIN pin, but also related to the pressure of the PIN pin. Pinneedle manufacturers said there are certain requirements for materials. Physical properties such as specific resistance, mechanical strength, and chemical properties directly affect contact resistance. In selecting the material, it is necessary to consider the combination of reducing the shrinkage resistance Rs and the sheet resistance Rb.
Technically speaking, the pin pin manufacturer can operate under normal current without causing the pin temperature to rise too high. Short-circuit current tolerance. Moderate insertion and extraction work. Overall, it's actually very easy to operate. Of course, it should be noted here that in the actual design process, the contact resistance is difficult to calculate, requiring a lot of experiments and good experience. In short, it is a high-precision product with a tolerance requirement of ± 0.001-± 0.0005. When ceramic ferrules are produced by ceramic powder injection molding, a series of high-demand environments such as acid resistance, corrosion resistance and high temperature resistance are required for core pins, especially industrial teeth such as hard alloy. High temperature corrosive environment operation. In the process of ceramic powder injection molding mold production of nano-zirconia, hard alloy core needle is suitable for its high temperature working environment, and its long-term durable operation makes the large-scale and batch production of ceramic ferrule become a trend. direct form of expression. The production of pin needle manufacturers is mainly based on different types of core pins, aiming at different equipment and operations. Ceramic ferrule pins and PIN pins can be customized according to requirements, and ferrule pins can be customized according to the matching requirements of ceramic powder injection molding molds. Due to the high precision requirements of ceramic ferrule, it is generally customized according to the drawing requirements. Pinneedle manufacturers thank new and old customers for their strong support, we ensure the reliability of product quality at the same time, let the majority of customers.
The content of the above article is for friends to tell the pinneedle manufacturers about the main points of product use, and also share a better pinneedle manufacturer in the content. If you have this requirement, you can check it out, hoping to help you.
