DEVELOP A NEW HIGH CURRENT CONTACT FOR AN EXISTING CONNECTOR

  Most compact connector systems have limited current carrying capacity due to the design of the contact. These contacts normally have one or two contact areas which limits the contacts ability to carry large amounts of current. This design, as shown in the figure, is a combination of a compact contact with the mating surface being shaped into louvers. The louvers provide additional contact areas, thereby providing parallel paths, for the current, which reduces the contacts impedance, resulting in a higher ampacity. Also, the louvered shape exposes more surfaces to air which reduces contact temperature and provides an additional increase in ampacity.The louvers are stamped and formed, during the manufacturing process, and are not a secondary operation. This reduces cost and provides a higher reliability by eliminating additional parts (e.g. separate louvers). Actual design of this concept will be determined by the configuration of the contact to be replaced.
