How High Pressure High Temperature Vacuum Sealed Connectors

High-pressure, high-temperature vacuum sealing connector is how to do? To achieve high temperature according to existing technology is not a big problem, with the development of science and technology, high-temperature materials are available, the current glass body better melting point of 1000 degrees. But to keep the insulation resistance normal, the material selection is very important, no resistance or very low when there is a breakdown phenomenon, can not be used. High voltage is different, accommodate more parameters, and the thickness of the contact parts, that is, the size of the current has a relationship, the current is better in the following 10A. When the current is not big, and the number of cores have a direct relationship, the more cores, that is, the creepage distance is small, the insulation resistance is not good control, the resistance is not up to the high-pressure case, there is a sparking phenomenon, it is dangerous, must keep the insulation resistance is normal in order to use. There is also a high air pressure and sintering depth is inevitable, it is recommended that the needle and the needle is better to have a metal isolation, that is, we usually socket eyelet sintering mode, because the vitreous insulates well in the case of pressure applied in a vacuum, the effect is not as strong as the metal shock resistance.
