Card Connector And Method For Producing Housing Assembly

Abstract

A card connector into and from which a memory card is detachably inserted and removed, includes contacts adapted to contact connection portions of the memory card, and a housing for arranging and holding the contacts. Metal plates made of a metal are installed in the housing so as to extend onto both sides in the width direction of the housing. The metal plates are integrally provided with connection portions to be connected to a substrate. A tray made of a metal is provided for loading a plurality of memory cards therein, and either of both ends of the tray in its width direction is bent substantially into an L-shape, which bent portion slidably engages the metal plate. The connector achieves a reduced overall height such as less than 2.0 mm and is also superior in safety.

1 . A card connector into and from which a memory card is detachably inserted and removed, comprising contacts adapted to contact connection portions of the memory card, and a housing for arranging and holding said contacts, wherein metal plates are mounted in said housing so as to extend onto both sides in the width direction of the housing, said metal plates integrally provided with connection portions to be connected to a reference potential, and a tray made of a metal is provided for loading one of a plurality of memory cards therein, both ends of said tray in its width direction being bent substantially into an L-shape, which bent portion slidably engages said metal plate to allow metal-to-metal sliding coupling. 
     
     
         2 . A card connector into and from which a memory card is detachably inserted and removed, comprising contacts adapted to contact connection portions of the memory card, and a housing for arranging and holding said contacts, wherein said housing is provided with extending portions extending onto both sides in its width direction, and a tray made of a metal is provided for loading one memory card therein, both ends of said tray in its width direction being bent substantially into an L-shape, which bent portion slidably engages said extending portion to allow metal-to-metal sliding coupling. 
     
     
         3 . The card connector as set forth in  claim 2 , wherein the extending portions of said housing are made of metal plates separate from said housing, and said metal plates are integrally provided with connection portions to be connected to a reference potential. 
     
     
         4 . The card connector as set forth in any one of  claims 1 ,  2  and  3 , wherein said tray is attached with a button to prevent erroneous insertion of said memory card and said button is made of a resin mounted thereon on either of both sides in the width direction and at the other end opposite to the end bent into the L-shape. 
     
     
         5 . The card connector as set forth in  claim 1 , wherein said metal plates are provided with projections on the side of insertion of the tray on both sides in the width direction, respectively, and said tray is provided on its side faces with anchoring grooves, respectively, with which said projections are in slidable engagement to fix the location. 
     
     
         6 . The card connector as set forth in  claim 1  or  3 , wherein a housing is used which is integrally formed with said contacts and said metal plates. 
     
     
         7 . The card connector as set forth in  claims 5  or  6 , wherein said side faces of said tray on both the sides in the width direction are provided at their free ends with folded-back portions, respectively. 
     
     
         8 . The card connector as set forth in  claim 4 , wherein said side faces of said tray on both the sides in the width direction are provided at their free ends with folded-back portions, respectively. 
     
     
         9 . The card connector as set forth in  claim 5 , wherein said side faces of said tray on both the sides in the width direction are provided at their free ends with folded-back portions, respectively. 
     
     
         10 . The card connector as set forth in  claim 6 , wherein said side faces of said tray on both the sides in the width direction are provided at their free ends with folded-back portions, respectively. 
     
     
         11 . The card connector as set forth in  claim 2  or  3 , wherein said extending portions are provided with projections on the side of insertion of the tray on both sides in the width direction, respectively, and said tray is provided on its side faces with anchoring grooves, respectively, with which said projections are in slidable engagement to fix the location.
