Definitions

  • This invention generally relates to card connectors mounted on electronic devices, such as cellular phones, telephones, PDAs (personal digital assistants), portable audio devices and cameras, and more specifically to a card connector with an ejection mechanism.
  • an IC card with a built-in CPU or memory IC, such as a SIM (Subscriber Identity Module) card, an MMC (Multimedia Card), an SD (Super Density) card, a Memory Stick or the likes.
  • SIM Subscriber Identity Module
  • MMC Multimedia Card
  • SD Super Density
  • the card connector has generally the following construction.
  • a plurality of contact terminals are provided that are connected to various signal processing circuits and a power supply circuit of an electronic device on which the card connector is mounted.
  • the contact terminals are brought into contact with a plurality of contact pads (forming a terminal array) formed on a front or back surface of the inserted IC card to electrically connect the IC card to the electronic device on which the connector is mounted.
  • Many of such card connectors have an ejection mechanism for removing the inserted IC card from the connector. Such a card ejection mechanism is an essential feature to ensure a large number of insertion- removal cycles of the IC card.
  • Such mechanisms are known from US 6,123,560 or US 6,899,555, both involving multiple part cam type mechanisms. Therefore, there is a need for an easy to manufacture card reader that does not display the above mentioned drawbacks.
  • a card reader would include a simple ejection mechanism, having a limited number of parts, and a simple cinematic.
  • the object of the present invention is to provide an easy to manufacture card connector compatible with today's miniaturization constraints.
  • Another object of the present invention is to provide a simple ejection mechanism, easy to manufacture and with fewer parts than the known mechanisms.
  • a further object of the invention is to provide a card reader with an ejection mechanism that can withstand a large number of insertion/removal cycles of the card without causing damage to ejection mechanism parts.
  • the invention takes advantage of the movable holding element that holds in a first position the card within the housing by acting against the biasing force applied to the card by the biasing element. When the holding element is moved away from the first element towards its second position, the card is no longer prevented from moving and the biasing element pushes the card outside the housing.

During insertion, stop 55 is kept away from open end thanks to a continuous force applied to pressing portion 56 (from fingers or card itself), as seen in Fig. 6 with holding element 46 in dotted lines. The card 100 must be pushed even further till pressing portion 56 is free to move again, i.e. till stop 55 can return thanks to resilient arm 50 to its rest position in front of open end 20. With card 100 pushed even further, till e.g. it comes into abutment with bottom end 21 , biasing element 58 is pressed against housing bottom end 21 , and applies through spring blade 59 a biasing force against the card to push it outside seat 2.
