Lisle, Ill. – Molex Inc. has introduced a wire-to-board, mid-range power connector that delivers 23.0A in a 5.70-mm footprint. The Mega-Fit power connector targets applications that require power from 14.0A to 23.0A per terminal.
These high-current terminals are well suited for a broad range of applications including consumer/home appliance, networking, telecommunications, industrial and commercial vehicle. As an example, the power connectors can be used when additional current carrying capacity is preferred rather than using the maximum power on a smaller connector.
In another cited example, the Mega-Fit connectors can replace lower power connectors used for current sharing. In some applications, design engineers may use current sharing, or split power between contacts with lower power connectors in order to achieve up to 23.0A. However, it is not only safer to use one current path with the Mega-Fit power connector, but it also reduces the PCB footprint, explained Molex.
“Design engineers are looking for power interconnects in the 14.0 to 23.0A range, but historically find their choices limited to either much lower or much higher amperage than required. This gap often leaves design engineers to choose between a connector that is too large for the application or splitting power between multiple contacts on a smaller connector, in both instances increasing the PCB space required,” said Corey Schroeder, global product manager, Molex, in a statement. “Molex solves this dilemma with its Mega-Fit power connectors, which feature high-current terminals and tight pitch and row spacing to enable delivery of more power per linear and square millimeter than other mid-range power products in the industry.”
Due to the safety requirements of power interconnects, the terminal interface and crimp section of the Mega-Fit connector integrates advanced technology including a split-box terminal design that staggers six contact points, each of which moves independently on a separate flexible beam in order to deliver a redundant, secondary current path for long-term reliability, said Molex.
The staggered contacts allow the front four “sacrificial” contacts to protect the two rear points of contact when un-mating, allowing the system to be "hot plugged" at 48V/23.0A and up to 30 cycles, said the company. In addition, for further durability and reliability, the terminals feature an extended barrel conductor crimp for an "extremely" strong terminal-to-wire retention.
