Definitions

  • This invention generally relates to the art of electrical connectors and, particularly, to a card connector which permits insertion and removal of a card-type memory medium (or memory card).
  • Japanese Unexamined Patent Publication No. Heisei 9-82411 which corresponds to International Publication WO 97/10691, and Japanese Unexamined Patent Publication No. Heisei 10-189139, for example.
  • These types of card connectors typically include an ejection mechanism which has an ejection rod movable in a direction generally parallel to the insertion and ejection direction of the memory card.
  • An ejection lever typically is engaged by a tip end of the ejection rod whereby a memory card inserted into the card connector can be ejected by pushing on the ejection rod and pivoting the ejection lever.
  • An object, therefore, of the invention is to provide a memory card connector with a new and improved ejection mechanism.
  • the card connector includes a generally flat housing for receiving a planar memory card in an insertion and ejection direction.
  • An ejection rod is reciprocally mounted on the housing for linear movement generally parallel to the insertion and ejection direction.
  • An ejection lever is pivotally mounted on the housing and is operatively associated with the ejection rod for pivoting the lever in response to linear movement of the rod.
  • the ejection lever is in the form of a generally flat plate generally coplanar with the memory card and having a side edge for engaging a front end of the memory card.
  • the ejection lever is elongated to define a first, proximal end and a second, distal end.
  • the lever is pivoted to the housing near the proximal end thereof, and the end engaging portion of the lever is near the distal end thereof.
  • the housing defines a card-receiving cavity enclosed by a cover which has a plurality of narrow ribs projecting into the cavity for engaging a flat surface of the memory card during insertion and ejection of the card into and out of the cavity. At least two of the narrow ribs are spaced transversely of the insertion and ejection direction of the memory card. At least two ribs are elongated in the insertion and ejection direction of the memory card.
  • the cover is fabricated of sheet metal material.
  • FIG. 1 is a top plan view of a card connector according to the invention
  • FIG. 2 is a side elevational view of the card
  • FIG. 3 is an enlarged vertical section taken generally alone line 3-3 of FIG. 1;
  • FIG. 4 is an illustration wherein the cover of the card connector has been removed, and showing a memory card inserted into the housing;
  • FIG. 5 is a view similar to that of FIG. 4, with the ejection mechanism in condition of ejecting the memory card.
  • a card connector generally designated 10 which includes an insulating or dielectric housing, generally designated 12, and a cover, generally designated 14.
  • the housing may be fabricated of molded plastic material or the like.
  • the cover may be stamped and formed of sheet metal material.
  • the housing and cover have a generally flat configuration and define a card-receiving cavity 16 (Fig. 3) therebetween for receiving a planar memory card 18 in an insertion and ejection direction indicated by double-headed arrow 20 (Fig. 1).
  • Dielectric housing 12 includes a body portion 22 within which a plurality of terminals, generally designated 24, are mounted in a side-by-side relationship transversely of the insertion and ejection direction 20.
  • the housing has a pair of side walls 26 (see Fig. 4) projecting from body portion 22.
  • the side walls, along with a bottom wall 28 (Fig. 3) of the housing, combine with cover 14 to define cavity 16.
  • Terminals 24 are mounted in body portion 22 of housing 12 and include contact portions 30 projecting into cavity 16 as is clearly seen in FIG. 3.
  • the terminals have tail portions 32 projecting out of the housing for connection, as by soldering, to appropriate circuit traces on a printed circuit board (not shown).
  • the housing has a plurality of mounting feet 34 for insertion into appropriate holes in the printed circuit board.
  • Contact portions 30 of terminals 24 are positioned within cavity 16 for engaging appropriate contacts (not shown) on the bottom surface of memory card 18 as is known in the art.
  • cover 14 of connector 10 is stamped and formed of sheet metal material.
  • the metal material may be stainless steel or the like.
  • the cover includes a top wall 36 covering the top of housing 12, along with side walls 38 which extend over and are latched to side walls 26 of the housing. Top wall 36 combines with bottom wall 28 and side walls 26 of the housing to define cavity 16.
  • top wall 36 of cover 14 includes a window 40, a pair of ribs
  • Ribs 44 are narrow in a direction transversely of the insertion and ejection direction of the memory card and are formed out of top wall 36 of cover 14 to an extent that the ribs project slightly into card-receiving cavity 16.
  • the narrow and thin ribs 42 and 44 are the only portions of cover 14 which engage the top surface of the memory card. Therefore, very little if any resistance is created between the card and the cover.
  • the ribs provide a smooth sliding engagement between the cover and the card.
  • Card connector 10 is provided with an ejection mechanism which includes an ejection rod 48 installed along one side wall 26 of housing 12. As best seen in FIG. 4, ejection rod 48 is bent at its outer end to define a pushing portion 50. A connecting portion 52 is secured to an inner end of the rod. The ejection rod is movable linearly back and forth along side wall 26 of the housing generally parallel to the insertion and ejection direction 20 of primary card
  • a coil spring 54 is connected between connecting portion 52 of the rod and the housing to constantly bias the ejection rod in an ejection direction as indicated by arrow 56 (Fig. 1).
  • flat plate or body portion 60 of the ejection lever is very thin. It has a thickness no greater than the thickness of memory card 18 as can be seen in FIG. 2.
  • the flat plate of the ejection lever has a thickness considerably less than the thickness of the memory card, as can be seen in comparing FIGS. 2 and 3. Therefore, the ejection mechanism, particularly the ejection lever, does not in any way interfere with downsizing or reducing the overall thickness of the card connector.
  • card connector 10 includes card lock 76 (Fig. 1), a detection switch 78, a biasing spring 80 and reinforcements 82 among other components which are conventional in card connectors, outside the scope of the inventive concepts herein and will not be described in detail.
  • front end 18a of the card first engages angled edge portion 74 and then engages end engaging portion 72 of convex side edge 66 of the ejection lever.
  • the initial moment arm of the lever is shorter during the heavier ejection forces and progressively increases toward the end of the flat thin plate 60 of the lever. This helps to prevent the flat thin plate from buckling during the initial ejection stroke of the memory card when the forces are the greatest.

Abstract

Un connecteur de carte mémoire destiné à un mécanisme d'éjection (10) comprend un boîtier généralement plat (12) destiné à accueillir une carte mémoire planaire (18) dans une direction d'insertion et d'éjection. Une tige d'éjection est montée en va et vient sur le boîtier pour pouvoir se déplacer de façon linéaire, généralement en parallèle à la direction d'insertion et d'éjection (20). Un levier d'éjection (58), monté pivotant sur le boîtier, est associé de façon fonctionnelle à la tige d'éjection (48) pour faire pivoter le levier en réponse au mouvement linéaire de la tige d'éjection. Le levier d'éjection possède une face généralement plate (60) qui est généralement coplanaire avec la carte mémoire, ladite plaque possédant un bord latéral (66) destiné à mettre en prise la carte. Le côté latéral du levier a une configuration généralement convexe définissant une partie entrant en prise avec le centre, destinée à mettre en prise la carte pendant la première phase du mouvement d'éjection et une partie de contact (70) avec l'extrémité destinée à mettre en prise la carte pendant une partie suivante du mouvement d'éjection de la carte.
