The pins of the cold-pressed terminal perforations need to be accurately positioned, sized properly, placed evenly, and have excellent weldability, which facilitates insertion and welding. During the entire installation process, it is necessary to withstand the high-temperature impact of heat treatment. In the welding process, infrared preheating and convection preheating are mainly used to conduct heat to the interface between the solder pin and the tin plate to melt the solder paste. The welding resistance of the contact is poor. When the starter motor or the line is short-circuited, large currents are applied. The head is welded firmly and cannot be released, among which the contact with pure silver is easier to weld. The main contact of the communication contactor should be silver base alloy with strong anti-weldability, such as silver iron, silver nickel and so on. In optical fiber communication (transmission) links, to complete different modules.
There is a need for a flexible connection between equipment and systems. It is necessary to have a device that can be detached (active) between fiber optics and fiber optics so that the light path can be transmitted in the desired channel to complete and complete the booking or hope. Intentions and requirements, equipment that can complete this function is called an adapter. For Fork Terminal Connectors identification, one or more of the following methods may be used to identify the device cold crimp terminals and specific wire ends. The symbology of the relevant product is selected to determine and identify the practice or relative orientation of the device cold-pressed terminal or specific wire end. The symbology of the relevant product is selected to determine and identify the color symbols of the device's cold-pressed terminals and the specific wire ends.
There is no air gap in the cold-pressed terminal magnetic system, and the residual magnetization is too large. Partially remove the pole face of the residual magnetic gap so that the gap is 0.1 ~ 0.3mm, or connect a 0.1uF capacitor in parallel with the two ends of the coil. The exposed contactor iron core is oily or greasy after being used for a period of time. The surface of the iron core is cleaned and the rust-proof grease is cleaned. The outer surface of the iron core is required to be flat, but it should not be exposed to light, otherwise it is easy to form a delayed release. Throughout the installation process, it is necessary to withstand the high temperatures in the preheat zone and the temperature that is conducted through the wave soldering to the terminal body. The solder must not affect the terminals. It must be easy to remove and there must be no residue. The entire installation process is necessary to be cleaned with water. Preheat temperatures often reach 100°C or higher, and peak temperatures of 280°C are not uncommon.
