Abstract

A connector plug includes a metallic shielding cover which is comprised of a first tubular body having a tip side and a second tubular body having a base side, the base side of the second tubular body being partially connected to the tip side of the first tubular body through a continuous connecting part, a plurality of contacts arranged in the shielding cover, and a coupling structure for fixedly coupling the second tubular body to the first tubular body. The structure includes at least one aperture provided in the first tubular body and at least one projection provided in the second tubular body so as to engage with the aperture, and a tip part of the projection is bent for locking the engagement between the aperture and the projection.

Claims

1. A connector plug, comprising:

a metallic shielding cover which includes a first tubular body having a tip side and a second tubular body having a base side, the base side of the second tubular body being partially connected to the tip side of the first tubular body through a continuous connecting part;

a plurality of contacts arranged in the shielding cover; and

means for fixedly coupling the second tubular body to the first tubular body so that deformation is discouraged from occurring in the continuous connecting part between these tubular bodies, the coupling means including at least one aperture provided in one of the first and second tubular bodies, at least one projection provided in the other tubular body so as to engage with the aperture, and means for locking the engagement between the aperture and the projection wherein the at least one projection has a tip part which extends through and out of the aperture wherein the means for locking is provided by bending or deforming the tip part of the projection from the outside of the metallic shielding cover.

2. The connector plug as claimed in claim 1, wherein the first tubular body is integrally formed with the second tubular body through the continuous connecting part, and the coupling means is provided on substantially the opposite side of the continuous connecting part.

3. The connector plug as claimed in claim 1, wherein the at least one aperture is provided in the tip side of the first tubular body and the at least one projection is provided in the base side of the second tubular body.

4. The connector plug as claimed in claim 3, wherein the at least one projection is integrally formed with the second tubular body.

5. The connector plug as claimed in claim 4, wherein the second tubular body is formed by folding a metallic plate member into a predetermined angular tube shape such that opposite edges thereof are in abutment with each other to form a joint.

6. The connector plug as claimed in claim 5, wherein the joint of the second tubular body has a protruding engaging part at the base side thereof, and the at least one projection includes two projections provided on the engaging part in a spaced manner, and the at least one aperture includes two apertures which engage with the two projections, respectively.

7. The connector plug as claimed in claim 6, wherein the coupling means further includes positioning means which is used when the projections are engaged with the apertures.

8. The connector plug as claimed in claim 7, wherein the positioning means includes a projection formed on the engaging part of the second tubular body, and an aperture formed on the tip side of the first tubular body to which the projection is fitted.

9. The connector plug as claimed in claim 8, wherein the projection of the positioning means is formed from a pair of pieces integrally formed with the opposite edges in the joint of the second tubular body.

10. The connector plug as claimed in claim 1, wherein the first tubular body has a step portion at the tip side thereof, and the at least one aperture is formed in the step portion.

11. A connector plug, comprising:

a metallic shielding cover which includes a first tubular body having a tip side and a second tubular body having a base side, the base side of the second tubular body being partially connected to the tip side of the first tubular body through a continuous connecting part;

a plurality of contacts arranged in the shielding cover; and

means for fixedly coupling the second tubular body to the first tubular body so that deformation is discouraged from occurring in the continuous connecting part between these tubular bodies, the coupling means providing an undisplaceable firm locking between the tip side of the first tubular body and the base side of the second tubular body at a location substantially opposite to the location of the continuous connecting part, wherein the coupling means includes at least one aperture provided in one of the first and second tubular bodies and at least one projection provided in the other tubular body and a means for locking the engagement between the aperture and the projection, in which the projection includes a tip part which extends through and out of the aperture, in which the means for locking is provided by bending or deforming the tip part of the projection from the outside of the metallic shielding cover.

12. A connector plug comprising:

a metallic shielding cover which includes a first tubular body having a tip side and a second tubular body having a base side, the base side of the second tubular body being partially connected to the tip side of the first tubular body through a continuous connecting part;

a plurality of contacts arranged in the shielding cover;

means for fixedly coupling the second tubular body to the first tubular body, the coupling means including at least one aperture provided in one of the first and second tubular bodies, at least one projection provided in the other tubular body so as to engage with the aperture, and means for locking the engagement between the aperture and the projection wherein the at least one aperture is provided in the tip side of the first tubular body and the at least one projection is provided in the base side of the second tubular body wherein the at least one projection is integrally formed with the second tubular body and further wherein the second tubular body formed by folding a metallic plate member into a predetermined angular tube shape such that opposite edges thereof are in abutment with each other to form a joint wherein the joint of the second tubular body has a protruding engaging part at the base side thereof, and the at least one projection includes two projections provided on the engaging part in a spaced manner, and the at least one aperture includes two apertures which engage with the two projections, respectively.

13. The connector plug of claim 12 wherein the coupling means further includes positioning means which is used when the projections are engaged with the apertures.

14. The connector plug of claim 13 wherein the positioning means includes a projection formed on the engaging part of the second tubular body, and an aperture formed on the tip side of the first tubular body to which the projection is fitted.

15. The connector plug of claim 14 wherein the projection of the positioning means is formed from a pair of pieces integrally formed with the opposite edges in the joint of the second tubular body.
