Power connector design key

- Nov 27, 2017 -

Power connector design is the key design is the formation of the female terminals and male contacts. If the design, process and material selection, plating, can lead to the contact point is not ideal or can not form a contact. On the contrary, excessive clamping positive force will lead to excessive wear and tear on the surface of the connector plating to reduce its mechanical life, that is, the number of connector plug. Contacts design lathe circular needle and terminals, stamping terminals. Table plating materials are gold, palladium, nickel, silver, tin, and so on. High conductivity of silver, but easy to change color, especially in sulfur-containing environment. Slight only affect the appearance of the serious but reduce the conductivity. Palladium-nickel has high hardness and low porosity, so its corrosion resistance is good. Gold has high chemical stability, low hardness and high cost. In contrast, each has its own advantages and disadvantages.
