Abstract

Rising of a forwardmost edge of a shield for a connector is prevented without requiring double-sided tape or the like. The connector includes an insulating material casing, terminals attached to the casing, and a metal plate shield on an upper surface of the casing. A terminal portion houses the terminals, with boss portions projecting widthwise of the terminal portion. A flange portion and receiving groove are provided on the forward edge of the casing. First and second concavities exists on upper surfaces of the terminal portion and the boss portion, respectively. First tab portions are pressed into the first concavities, and second tab portions are pressed into the second concavities, making the shield inseparable from the casing. A bent portion at a forwardmost edge of the shield portion is received within the receiving groove for preventing an edge of the shield portion from rising up from the terminal portion.

Claims

1. A connector comprising a substantially rectangular casing formed by an insulator, a plurality of terminals disposed in a widthwise direction of said casing, and a plate-shaped shield disposed on an upper surface of said casing,

said casing comprising:

a terminal portion in which said terminals are disposed;

a boss portion projecting in a widthwise direction from said terminal portion; and

a receiving groove comprising an inclined surface slanted in a downward direction and disposed in a vicinity of a front edge portion of said terminal portion,

wherein a first groove portion is disposed on said terminal portion oriented downward from an upper surface thereof and between said terminals, and a second groove portion is disposed on said boss portion oriented downward from an upper surface thereof; and

said shield comprising;

a shield portion formed of a width narrower than said terminal portion of said casing and which covers an upper surface of said terminal portion;

an expanded-width portion disposed on a rearward position of said shield portion and expanding widthwise toward said boss portion;

a lead portion extending from said expanded-width portion toward the rear of said casing; and

a bent portion that is curved downwardly at a forward edge of said shield portion, wherein a lower surface of said bent portion is received along said inclined surface of said receiving groove,

wherein a first tab portion is provided for insertion by pressing into said first groove portion in a vicinity of a front edge portion of said shield portion, and a second tab portion is provided for insertion by pressing into said second groove portion at an edge portion of the widthwise direction of said expanded-width portion.

3. The connector according to claim 1 or 2, wherein said bent portion extends substantially from one end to another end of the forward edge of said shield portion.

2. A connector comprising a substantially rectangular casing formed by an insulator, a plurality of terminals disposed in a widthwise direction of said casing, and a plate-shaped shield disposed on an upper surface of said casing,

said casing comprising:

a terminal portion in which said terminals are disposed; and

a receiving groove comprising an inclined surface slanted in a downward direction and disposed in a vicinity of a front edge portion of said terminal portion; and

said shield comprising;

a shield portion formed of a width narrower than said terminal portion of said casing and which covers an upper surface of said terminal portion;

an expanded-width portion disposed on a rearward position of said shield portion and expanding widthwise toward a widthwise edge portion of said terminal portion;

a lead portion extending from said expanded-width portion toward the rear of said casing; and

a bent portion that is curved downwardly at a forward edge of said shield portion, wherein a lower surface of said bent portion is received along said inclined surface of said receiving groove,

wherein a through hole is provided penetrating through the front and rear in the vicinity of at least a front edge portion of said shield portion, and a protuberance is provided on said terminal portion, inserted in said through hole and projecting upwardly from a front surface of said shield portion, and

wherein when said shield is attached to said casing, a portion of said protuberance projecting from said through hole is fastened by caulking.
