Abstract
Abstract A shielded electric connector comprises contact pins each of which includes a contact portion on one end thereof for coming into contact with a mating contact piece, and a joint portion on the other end thereof for connecting an electric wire to be connected, an insulating housing in which the contact pins are disposed and held, a shield hood member which includes a front envelope that encloses the contact pins disposed and held in the insulating housing and a rear envelope that is formed so as to be continuous to and unitary with the front envelope, the hood member having open on only one side and formed with an electric wire lead-out portion, a shield lid member adapted to be coupled to the shield hood member in a manner to close the opening of the shield hood member, and a shield connection part adapted to be connected to a shield layer of the electric wires. A method of connecting electric wires to such shielded electric connector is also disclosed.

Claim 1
Independent Claim
546 words
A method of connecting electrical wires to a shielded electrical connector, said method comprising: providing contact pins each having a mating contact piece on one end thereof and a joint portion on the other end thereof for connecting an electric wire; disposing and holding said contact pins in an insulating housing, said insulating housing having an elongated rectangular cross-section having long sides and short sides; providing a shield hood member; providing a shield lid member; placing a flat portion of said shield lid member on said insulating housing with a said long side of said insulating housing on a surface of said flat portion, providing a shield connecting portion at a generally central portion of a rear end of said flat portion, said shield connecting portion being substantially U-shaped and extending in a direction substantially perpendicular to the plane of said flat portion and to the surface of said flat portion on which said insulating housing is placed, and providing a pair of engaging arms, one at each side of said flat portion and extending in a direction substantially perpendicular to the plane of said flat portion and to the surface of said flat portion on which said insulating housing is placed, said shield hood member having a front envelope which surrounds at least said contact portions of said contact pins disposed in said insulating housing, said front envelope being hollow and having an elongatedly rectangular cross-section having long sides and short sides, a rear envelope being attached to a rear end of said front envelope and having an electric wire lead-out portion extending from a generally central portion of the rear end of said rear envelope, said lead-out portion having a U-shaped groove, said rear envelope having walls which are completely continuous, except for an opening which is completely closed by said flat portion of said shield lid member, said walls including an enveloping flat wall portion extending from one of the long sides of the rear end of said front envelope to said electric wire lead-out portion, side wall portions upright at each side of said enveloping flat wall portion and extending rearwardly from each of the short sides of the rear end of said front envelope, and shoulder side wall portions upright at each side of said enveloping flat wall portion and extending from a rear end of each of said side wall portions to each side of said electric wire lead-out portion, providing each of said side wall portions with an engaging portion which is engaged by one of said engaging arms of said shield lid member, connecting terminal end parts of said electric wires to said joint portions of the corresponding contact pins and a shield layer of said electric wires to said shield connecting portion by crimping, and installing said insulating housing in said shield hood member with the contact portions of said contact pins being surrounded by said front envelope of said shield hood member and said shield connecting portion being disposed in said U-shaped groove of said electric wire lead-out portion, and coupling said shield lid member to said shield hood member to close said opening of said shield hood member by engaging each of said engaging arms with the corresponding engaging portion of said shield hood member.
Claim 2
Independent Claim
546 words
A method of connecting electrical wires to a shielded electrical connector, said method comprising: providing contact pins each having a mating contact piece on one end thereof and a joint portion on the other end thereof for connecting an electric wire; disposing and holding said contact pins in an insulating housing, said insulating housing having an elongated rectangular cross-section having long sides and short sides; providing a shield hood member; providing a shield lid member; placing a flat portion of said shield lid member on said insulating housing with a said long side of said insulating housing on a surface of said flat portion, providing a shield connecting portion at a generally central portion of a rear end of said flat portion, said shield connecting portion being substantially U-shaped and extending in a direction substantially perpendicular to the plane of said flat portion and to the surface of said flat portion on which said insulating housing is placed, and providing a pair of engaging arms, one at each side of said flat portion and extending in a direction substantially perpendicular to the plane of said flat portion and to the surface of said flat portion on which said insulating housing is placed, said shield hood member having a front envelope which surrounds at least said contact portions of said contact pins disposed in said insulating housing, said front envelope being hollow and having an elongatedly rectangular cross-section having long sides and short sides, a rear envelope being attached to a rear end of said front envelope and having an electric wire lead-out portion extending from a generally central portion of the rear end of said rear envelope, said lead-out portion having a U-shaped groove, said rear envelope having walls which are completely continuous, except for an opening which is completely closed by said flat portion of said shield lid member, said walls including an enveloping flat wall portion extending from one of the long sides of the rear end of said front envelope to said electric wire lead-out portion, side wall portions upright at each side of said enveloping flat wall portion and extending rearwardly from each of the short sides of the rear end of said front envelope, and shoulder side wall portions upright at each side of said enveloping flat wall portion and extending from a rear end of each of said side wall portions to each side of said electric wire lead-out portion, providing each of said side wall portions with an engaging portion which is engaged by one of said engaging arms of said shield lid member, connecting terminal end parts of said electric wires to said joint portions of the corresponding contact pins and a shield layer of said electric wires to said shield connecting portion by crimping, and installing said insulating housing in said shield hood member with the contact portions of said contact pins being surrounded by said front envelope of said shield hood member and said shield connecting portion being disposed in said U-shaped groove of said electric wire lead-out portion, and coupling said shield lid member to said shield hood member to close said opening of said shield hood member by engaging each of said engaging arms with the corresponding engaging portion of said shield hood member.
