Abstract
Abstract A miniature electrical contact terminal (1) for a shielded cable having a central conductor includes a shield jacket (3) including a contact support section (6), a pair of opposed tool openings (10, 11), a shield braid crimping section (7) having crimping tabs for crimping a shield braid of the shielded cable, and an outer sheath crimping section (8) having crimping tabs for crimping an outer sheath of the shielded cable; an insulator block (4) fitted in the contact support section; and a signal line contact (5) having a closed barrel fitted through the insulator block such that a rear portion thereof is placed within the tool openings, whereby the rear portion of the closed barrel, the shield braid crimping section, and the outer sheath crimping section are crimped simultaneously to the central conductor, the shield braid, and the outer sheath of the shielded cable, respectively.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A miniature electrical contact terminal for a shielded cable having a central conductor comprising: a shield jacket made from sheet metal to have a contact support section, a pair of opposed tool openings, a U-shaped shield wire crimping section having crimping tabs for crimping a shield wire of said shielded cable, and a U-shaped outer sheath crimping section having crimping tabs for crimping an outer sheath of said shielded cable; an insulator block fitted in said contact support section; and a signal line contact having a closed barrel fitted through said insulator block such that a rear portion thereof is placed within said tool openings, whereby said rear portion of said closed barrel, said shield wire crimping section, and said outer sheath crimping section are crimped simultaneously to said central conductor, said shield wire, and said outer sheath of said shielded cable, respectively.
Claim 2
Dependent Claim
143 words
A miniature electrical contact terminal for a shielded cable having a central conductor comprising: a shield jacket made from sheet metal to have a contact support section, a pair of opposed tool openings, a U-shaped shield wire crimping section having crimping tabs for crimping a shield wire of said shielded cable, and a U-shaped outer sheath crimping section having crimping tabs for crimping an outer sheath of said shielded cable; an insulator block fitted in said contact support section; and a signal line contact having a closed barrel fitted through said insulator block such that a rear portion thereof is placed within said tool openings, whereby said rear portion of said closed barrel, said shield wire crimping section, and said outer sheath crimping section are crimped simultaneously to said central conductor, said shield wire, and said outer sheath of said shielded cable, respectively.
Claim 3
Dependent Claim
39 words
The miniature electrical contact of claim 1, wherein said rear portion of said closed barrel is crimped at least two places on each of opposite sides of said rear portion with two pairs of narrow flat-plate like crimping dies.
Claim 4
Dependent Claim
151 words
A miniature electrical contact terminal for a shielded cable having a central conductor comprising: a shield jacket made from sheet metal to have a contact support section, a pair of opposed tool openings, a U-shaped shield wire crimping section having crimping tabs for crimping a shield wire of said shielded cable, and a U-shaped outer sheath crimping section having crimping tabs for crimping an outer sheath of said shielded cable; an insulator block fitted in said contact support section; and a signal line contact having a closed barrel fitted through said insulator block such that a pair of opposed flat pieces extending from a rear end thereof in the axial direction is placed within said tool openings, whereby said flat pieces, said shield braid crimping section, and said outer sheath crimping section are crimped simultaneously to said central conductor, said shield wire, and said outer sheath of said shielded cable, respectively.
Claim 5
Dependent Claim
151 words
A miniature electrical contact terminal for a shielded cable having a central conductor comprising: a shield jacket made from sheet metal to have a contact support section, a pair of opposed tool openings, a U-shaped shield wire crimping section having crimping tabs for crimping a shield wire of said shielded cable, and a U-shaped outer sheath crimping section having crimping tabs for crimping an outer sheath of said shielded cable; an insulator block fitted in said contact support section; and a signal line contact having a closed barrel fitted through said insulator block such that a pair of opposed flat pieces extending from a rear end thereof in the axial direction is placed within said tool openings, whereby said flat pieces, said shield braid crimping section, and said outer sheath crimping section are crimped simultaneously to said central conductor, said shield wire, and said outer sheath of said shielded cable, respectively.
