Contact retention plate for power connector assembly

A method of manufacturing a power connector assembly, the method comprising:

• positioning a housing of the power connector assembly immediately forward of a contact retention plate using a power connector assembly holder such that a cavity of the housing faces the contact retention plate;
• positioning the power connector assembly in a first insertion position relative to the contact retention plate such that a contact insertion port of the contact retention plate is aligned with a first contact chamber of the housing;
• loading a first contact of a plurality of contacts through the contact insertion port of the contact retention plate into the first contact chamber at the first insertion position using a contact feeder;
• repositioning the power connector assembly to a second insertion position relative to the contact retention plate such that the contact insertion port of the contact retention plate is aligned with the first contact chamber of the housing at a location above the first contact, wherein the contact retention plate blocks the first contact from removal from the first contact chamber when the power connector assembly is positioned in the second insertion position;
• and
• loading a second contact of the plurality of contacts through the contact insertion port of the contact retention plate into the first contact chamber at the second insertion position using the contact feeder such that the second contact is stacked above the first contact.
