A power connector comprises a slidably positionable earth pin. The earth pin is able to be positioned in a travel, or small form factor and in an operational form factor. The housing of the connector comprises a member having a slot that defines a sliding path for the earth pin. The member also has two sets of grooves for receiving a set of spring loaded protrusions on the earth pin. The protrusions come to rest in one of the sets of grooves thereby defining a small form factor and an operational form factor.
