Electrical connector shield case

Claim 2

An electrical connection shield case for enclosing an insulation housing having a vertical side wall surrounding a plurality of contacts, a horizontal flange integral with said vertical side wall, and first fastener means provided in said horizontal flange of said insulation housing, which comprises: a cylindrical member made of a metal sheet, opposite free ends of which abut each other at a seam of said cylindrical member which fits over said vertical side wall of said insulation housing; locking means provided on said opposite free ends to prevent opening of said cylindrical member; and second fastener means provided on a rear edge of said cylindrical member across said seam for engagement with said first fastener means, thereby preventing any offsetting, overlapping and separation of said opposite free ends.

Claim 3

The electrical connector shield case of claim 1, wherein said first and second fastener means are a slot and a spearhead-shaped tab, respectively.

Claim 4

The electrical connector shield case of claim 1, wherein said cylindrical member has a U-section flange on its front edge to fit over a top edge of said vertical side wall of said insulation housing.

Claim 5

An electrical connector shield case for enclosing an insulation member, which comprises: a first case section with a first cylindrical member made of a first metal sheet, opposite first free ends of which abut each other at a first seam; first locking means provided on said first free ends to prevent opening of said first cylindrical member; first fastening means provided on a rear edge of said first cylindrical member across said first seam; a second case section with a second cylindrical member made of a second metal sheet, opposite second free ends of which abut each other at a second seam; second locking means provided on said second free ends to prevent opening of said second cylindrical member; second fastening means provided in an area on a front edge of said second cylindrical member, in which said second seam is absent, for engagement with said first fastening means, thereby preventing offsetting, overlapping, and separation of said first free ends.

Claim 6

An electrical connector shield case for enclosing an insulation member, which comprises: a first case section with a first cylindrical member made of a first metal sheet, opposite first free ends of which abut each other at a first seam; first locking means provided on said first free ends to prevent opening of said first cylindrical member; first fastening means provided on a rear edge of said first cylindrical member across said first seam; a second case section with a second cylindrical member made of a second metal sheet, opposite second free ends of which abut each other at a second seam; second locking means provided on said second free ends to prevent opening of said second cylindrical member; second fastening means provided in an area on a front edge of said second cylindrical member, in which said second seam is absent, for engagement with said first fastening means, thereby preventing offsetting, overlapping, and separation of said first free ends.

Claim 7

The electrical connector shield case of claim 4, wherein said first fastening means is formed in a spearhead shape and said second fastening means is a slot provided in a flange extending from said front edge of said second cylindrical member.

Claim 8

The electrical connector shield case of claim 4, wherein said first cylindrical member has at least one protuberance for making a spring contact with a mating connector shield case.
