Electrical connector shield with gap shielding
A shielded connector comprises an inner housing accommodating a contact and a shield shell surrounding the inner housing. The inner housing has a catch protrusion. The shield shell has a shell main body formed with an opening extending through the shield shell and a cover tab supported by the shell main body. The catch protrusion is inserted from an inside of the shield shell into the opening and the cover tab covers the opening while being set back from the catch protrusion toward an outside of the shield shell.
1. A shielded connector, comprising:
an inner housing accommodating a contact and having a catch protrusion; and
a shield shell surrounding the inner housing and having a shell main body formed with an opening extending through the shield shell and a cover tab supported by the shell main body in a cantilever-like manner with a free end portion of the cover tab having a contact portion protruding toward the shell main body, the catch protrusion inserted from an inside of the shield shell into the opening and the cover tab covering the opening while being set back from the catch protrusion toward an outside of the shield shell.
2. The shielded connector of claim 1 , wherein the free end portion of the cover tab has a pressed protrusion protruding from a portion of the cover tab covering the opening toward an outside of the shield shell.
3. The shielded connector of claim 2 , wherein the pressed protrusion comes into contact with the outer housing, pressing the free end portion between the outer housing and the shell main body.
4. The shielded connector of claim 1 , wherein the shell main body is formed in a tubular shape and has a seam along an axial-line direction.
5. The shielded connector of claim 4 , wherein the cover tab is supported in a cantilever-like manner at either one of a first end portion and a second end portion of the shell main body, the first end portion and the second end portion of the shell main body are joined together at the seam.
6. The shielded connector of claim 5 , wherein the cover tab extends in a direction perpendicular to the axial-line direction over the opening at the outside of the shield shell.
7. The shielded connector of claim 1 , further comprising an outer housing surrounding the outside of the shield shell.
8. The shielded connector of claim 7 , wherein the cover tab is held between the outer housing and the shell main body, and is pressed toward the shell main body by an apex portion of a pressing protrusion of the outer housing.
9. The shielded connector of claim 8 , wherein the outer housing has a catch beam caught by the cover tab.
10. The shielded connector of claim 1 , wherein the outer housing has a pressing protrusion protruding toward an inside of the outer housing and toward the free end portion of the cover tab.
11. The shielded connector of claim 10 , wherein the free end portion of the cover tab is pressed between the pressing protrusion and the shell main body.
12. The shielded connector of claim 11 , wherein the outer housing is formed with a guide groove capable of guiding the cover tab in a direction of insertion for the shield shell to be inserted into the outer housing.
13. The shielded connector of claim 12 , wherein the cover tab extends in a direction perpendicular to the direction of insertion.
14. The shielded connector of claim 13 , wherein the pressing protrusion and the catch beam caught by the cover tab are formed inside the guide groove.
15. The shielded connector of claim 14 , wherein the catch beam is disposed nearer a supported end of the cover tab than the pressing protrusion.
