Push button structure for a card connector

摘要

A push button structure for a card ejector mechanism of a card connector mounted in a portable computer comprises a first section fixed to a push rod of the ejector mechanism and a second section linearly movable and pivotably connected to the first section wherein the second section can be movably retained at first, second, and third positions relative to the first section. At the first position, the second section protrudes from a housing of the computer a sufficient distance so that a push force can be easily exerted on the push button structure. At the second position, the second section is pivoted relative to the first section to be substantially flush with an outside of the housing so that the push button structure will not be susceptible to damage by an external force. At the third position, the second section is pushed to engage with the first section so that a push force can be exerted on the push rod to activate a card ejecting plate to eject a card inserted into the card connector.
