Power connector

Abstract

This invention discloses a power connector, comprising: an insulating housing, a first power terminal, and a second power terminal. The first power terminal and the second power terminal are stacked within the insulating housing. A first contact of the first power terminal and a second contact of the second power terminal enter a slot in the insulating housing and are adjacent to each other along the depth direction of the slot. The second contact is configured to make electrical contact with the insert only after the first contact has made electrical contact with the insert, thereby preventing arcing and damage to the second contact. Furthermore, when the second contact makes electrical contact with the insert, the first contact is lifted away from the insert.
