Abstract

A shield shell (40) has a base (41) and a lid (42) formed together through a pair of coupling pieces (47). A housing (20) on which terminal members (21) are mounted is put on the base (41), and distal ends of shielded electric wires (11) are mounted on the housing (20). A core (12) in each shielded electric wire (11) is brought into insulation displacement in the terminal member (21), and a cover (35) closes the housing (20). The lid (42) is bent at the coupling pieces (47). Thus, the housing (20) is disposed and locked between the base (41) and the lid (42). Contact pieces (56) on the lid (42) of the shield shell (40) pass through windows (38) in the cover (38) and elastically contact a short circuit member (18).

Claims

1. An electrical connector for a plurality of juxtaposed shielded electric wires, each said shielded electric wire having a core and a shielding layer, the connector comprising:

a housing;

a plurality of terminals in the housing and configured for connection to the cores of the shielded electric wires; and

a shield shell covering said housing and configured for connection to the shielding layers of said shielded electric wires, said shield shell comprising a base mounted to said housing and a lid formed integrally with said base so that said lid of said shield shell can be moved to an open position and a closing position with respect to said base of said shield shell, said base and said lid of said shell being formed integrally from a single plate through coupling pieces, each of said coupling pieces being provided with a fold line and two notches disposed on opposite respective ends of the fold line on each coupling pieces, said notches and said fold lines being substantially colinear for enablinig the lid to be folded precisely along the fold lines and relative to the base.

2. An electrical connector for a plurality of juxtaposed shielded electric wires, each said shielded electric wire having a core and a shielding layer, the connector comprising:

a housing with opposite top and bottom surfaces and opposite front and rear surfaces;

a plurality of terminals in the housing and configured for connection to the cores of the shielded electric wires; and

a shield shell covering said housing and configured for connection to the shielding layers of said shielded electric wires, said shield shell comprising a base mounted to said bottom surface of said housing and a lid formed integrally with said base so that said lid of said shield shell can be moved to an open position and a closing position with respect to said base of said shield shell, said base and said lid of said shield shell being formed integrally from a single plate through foldable coupling pieces aligned substantially perpendicular to said base and said lid, wherein escape recesses are formed on said top surfaces of said housing at locations that oppose the folded portions of said coupling pieces, portions of the top surface at he escape recesses being aligned to the front surface at an acute angle so that said lid initially can be folded relative to the coupling pieces more than a right angle.

3. The connector of claim 2, wherein said base and said lid of said shell are substantially parallel when said lid is in said closing position, said foldable coupling pieces having a portion extending substantially perpendicularly from said base and a portion folded through an angle of greater than 90°

and aligned with one of said escape recesses of said housing.

4. The connector the claim 2, wherein the housing has opposite top and bottom surfaces and opposite front and rear ends extending between the top and bottom surfaces, the foldable coupling pieces of the shield shell being disposed substantially adjacent the front end of the housing, the escape recesses being formed on the top surface of the housing adjacent the front end of the housing and aligned with the respective foldable coupling pieces, each said escape recess being tapered downwardly and rearwardly.

5. An electrical connector for a plurality of juxtaposed shielded electric wires, each said shielded electric wire having a core and a shielding layer, the connector comprising:

a housing;

a plurality of electrically separated terminals in the housing and configured for connection respectively to the cores of the shielded electric wires;

a cover retractably coupled to said housing to maintain a contact condition between said shielded electric wires and said terminals by pushing said shielded electric wires; and

a shield shell covering said housing and said cover and configured for connection to the shielding layers of said shielded electric wires, said shield shell comprising a base mounted to said housing and a lid formed integrally with said base so that said lid of said shield shell can be moved to an open position and a closing position with respect to said base of said shield shell wherein said lid of said shield is folded in a longitudinal direction of said shielded electric wires with respect to a front edge of said housing to close said housing, and said cover is supported on a side end of said housing retractably in a width direction of said electric wires.

6. The connector of claim 5, wherein said base and lid of said shield shell are formed integrally through foldable coupling pieces from a sheet of plate.

7. The connector of claim 6, wherein each of said coupling pieces is provided on the opposite ends of a fold line with notches and a bead for reinforcement is formed on each said coupling piece substantially adjacent said fold line.

8. The connector of claim 7, wherein escape recesses are formed on surfaces of said housing that oppose folded portions of said coupling pieces so that said coupling pieces can be folded more than a predetermined foldable angle.

9. The connector of claim 5, wherein said housing has opposite top and bottom surfaces, said base of said shield shell being formed with a plurality of pressing pieces configured for elastically contacting the bottom surface of the housing and urging the housing towards the lid of the shield shell.
