Abstract
An apparatus and method are provided for removing an electronic module from a connector within a housing. The module is both insertable and removable through an opening within the housing. The apparatus includes a lever arm which is situated mainly internal to the housing except for an end portion of the arm which extends sufficiently far outside of the housing to enable a user to grasp the arm end portion. The lever arm includes first and second engagement points for contacting the module to assist in the extraction of the module from the housing. First, when the user initially pulls on the arm end portion, this action applies a first relatively high level extraction force to the module at said first engagement point. In this manner, the module is removed from the connector via a relatively high first mechanical advantage exhibited by the arm end portion with respect to the first engagement point. Secondly, when the user continues to pull on the arm end portion, this action applies a second extraction force less than the first extraction force to the module at the second engagement point. In this manner, the module is moved sufficiently far through the opening to enable the user t…
