Abstract

An outer conductor terminal by which productivity of the outer conductor terminal having crimping portions provided with reticulated knurling grooves on the inner surfaces can be improved. An outer conductor terminal 4 of a shielded connector 1 is provided with a pair of shielded conductor crimping portions 6 and 7 to be crimped onto a shielded conductor Wd which is exposed by stripping a sheath We at an end of a shielded cable W. The shielded conductor crimping portions are crimped such that the shielded conductor crimping portion 7 overlaps the shielded conductor crimping portion 6. Reticulated knurling grooves 10 are formed on the inner surfaces of the shielded conductor crimping portions 6 and 7, but they are not formed on an overlapping portion of the inner surface of the shielded conductor crimping portion 7 which is placed on the shielded conductor crimping portion 6.

Claims

1. An outer conductor terminal of a shielded connecter which is connected to an end of a shielded cable having a shielded conductor which covers an outer surface of a signal wire and a sheath which covers an outer surface of the shielded conductor, the outer conductor terminal comprising:

first and second shielded conductor crimping portions arranged to be crimped onto the shielded conductor which is exposed by stripping the sheath at the end of the shielded cable, wherein the shielded conductor crimping portions are crimped such that the second shielded conductor crimping portion overlaps the first shielded conductor crimping portion; and

reticulated knurling grooves formed on inner surfaces of the first and second shielded conductor crimping portions, wherein the reticulated knurling grooves are not formed on an overlapping portion of the inner surface of the second shielded conductor crimping portion which is placed on the first shielded conductor crimping portion.

2. The outer conductor terminal according to claim 1, further comprising:

a tapered surface formed on an outer surface at a tip of the first shielded conductor crimping portion; and

a tapered surface formed on an inner surface at a tip of the second shielded conductor crimping portion, which can slide on the tapered surface of the outer surface of the first shielded conductor crimping portion,

wherein the reticulated knurling grooves are not formed on a portion of the inner surface of the first shielded conductor crimping portion which corresponds to the tapered surface of the outer surface of the first shielded conductor crimping portion.

3. The outer conductor terminal according to claim 1, further comprising:

first and second sheath crimping portions arranged to be crimped onto the sheath, wherein the first and second sheath crimping portions are crimped such that the second sheath crimping portion overlaps the first sheath crimping portion; and

reticulated knurling grooves formed on inner surfaces of the first and second sheath crimping portions, wherein the reticulated knurling grooves are not formed on an overlapping portion of the inner surface of the second sheath crimping portion which is placed on the first sheath crimping portion.

4. The outer conductor terminal according to claim 3, further comprising:

a tapered surface formed on an outer surface at a tip of the first sheath crimping portion; and

a tapered surface formed on an inner surface at a tip of the second sheath crimping portion, which can slide on the tapered surface of the first sheath crimping portion,

wherein the reticulated knurling grooves are not formed on a portion of the inner surface of the first sheath crimping portion which corresponds to the tapered surface of the outer surface of the first sheath crimping portion.

5. The outer conductor terminal according to claim 2, further comprising:

first and second sheath crimping portions arranged to be crimped onto the sheath, wherein the first and second sheath crimping portions are crimped such that the second sheath crimping portion overlaps the first sheath crimping portion; and

reticulated knurling grooves formed on inner surfaces of the first and second sheath crimping portions, wherein the reticulated knurling grooves are not formed on an overlapping portion of the inner surface of the second sheath crimping portion which is placed on the first sheath crimping portion.

6. The outer conductor terminal according to claim 5, further comprising:

a tapered surface formed on an outer surface at a tip of the first sheath crimping portion; and

a tapered surface formed on an inner surface at a tip of the second sheath crimping portion, which can slide on the tapered surface of the first sheath crimping portion,

wherein the reticulated knurling grooves are not formed on a portion of the inner surface of the first sheath crimping portion which corresponds to the tapered surface of the outer surface of the first sheath crimping portion.
