Abstract
Abstract A shield connector has a double retainment mechanism used for electric wirings of automobiles, and the object thereof is to provide a shield connector that is highly reliable and excellent in operability. Retaining arms for a terminal are arranged on a terminal housing so as to be erectable; in the retaining arms, a retaining projection having a tapered portion is arranged; the terminal housing having the terminal received in a terminal receiving chamber primarily retained by a retaining strip arranged on the terminal receiving chamber is inserted into an inner sleeve of a housing cover; whereby the tapered portion comes in contact with a guide slope arranged in the inner sleeve of the housing cover and is urged to thereby cause the retaining arms to fall down. As a result, the retaining projection gets fitted into a retaining portion of the terminal, so that the terminal can be doubly retained.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal to be received in the terminal receiving chamber; first locking means provided on said terminal housing for locking the terminal in the terminal receiving chamber; and second locking means provided on said terminal housing for secondarily locking the terminal in the terminal receiving chamber as the terminal housing is inserted into the sleeve of the housing cover, wherein said first locking means locks said terminal before said terminal housing is even partially inserted into said sleeve of said housing cover.
Claim 2
Dependent Claim
122 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal to be received in the terminal receiving chamber; first locking means provided on said terminal housing for locking the terminal in the terminal receiving chamber; and second locking means provided on said terminal housing for secondarily locking the terminal in the terminal receiving chamber as the terminal housing is inserted into the sleeve of the housing cover, wherein said first locking means locks said terminal before said terminal housing is even partially inserted into said sleeve of said housing cover.
Claim 3
Dependent Claim
41 words
A shield connector of claim 1, wherein said first locking means includes a projecting finger extending into said terminal receiving chamber, and said second locking means includes a retaining projection flexibly attached to said terminal housing and including a tapered portion.
Claim 4
Dependent Claim
97 words
A shield connector as claimed in claim 2, wherein said inner sleeve includes a sloped surface constituting a guide slope, and wherein when the terminal housing, retaining the terminal received in the terminal receiving chamber by the projecting finger, is inserted into the inner sleeve of the housing cover, the tapered portion of the retaining projection is brought into contact with the guide slope of the housing cover and urged, so that the retaining projection is engaged with a retaining portion of the terminal to thereby allow the terminal to be doubly retained in the terminal housing.
Claim 5
Dependent Claim
121 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal receivable in the terminal receiving chamber; and locking means for locking the terminal in the terminal receiving chamber, said locking means being slidably received in said terminal housing so as to be movable from an unlocked position disengaged from said terminal to a locked position engaged with said terminal, wherein said terminal housing includes grooves and said locking means includes locking projections received in said grooves.
Claim 6
Dependent Claim
121 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal receivable in the terminal receiving chamber; and locking means for locking the terminal in the terminal receiving chamber, said locking means being slidably received in said terminal housing so as to be movable from an unlocked position disengaged from said terminal to a locked position engaged with said terminal, wherein said terminal housing includes grooves and said locking means includes locking projections received in said grooves.
Claim 7
Dependent Claim
124 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal receivable in the terminal receiving chamber; and locking means for locking the terminal in the terminal receiving chamber, said locking means being slidably received in said terminal housing so as to be movable from an unlocked position disengaged from said terminal to a locked position engaged with said terminal, wherein said locking means includes hinge portions and an engagement portion, said engagement portion being thicker than said hinge portion.
Claim 8
Dependent Claim
124 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal receivable in the terminal receiving chamber; and locking means for locking the terminal in the terminal receiving chamber, said locking means being slidably received in said terminal housing so as to be movable from an unlocked position disengaged from said terminal to a locked position engaged with said terminal, wherein said locking means includes hinge portions and an engagement portion, said engagement portion being thicker than said hinge portion.
Claim 9
Dependent Claim
148 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal insertable into the terminal receiving chamber in a direction of a front end of said terminal housing; locking means for locking the terminal in the terminal receiving chamber, said locking means including an inclined hinge portion extending from said front end of said terminal housing toward a rear end thereof and an engagement portion connected to said hinge portion, wherein as said terminal housing is inserted into said inner sleeve, said locking means abuts against said guide slope so that said hinge portion is rotated causing said engagement portion to engage said terminal.
Claim 10
Dependent Claim
148 words
A shield connector comprising: a housing cover having an electrically conducting inner sleeve, a guide slope being arranged in the inner sleeve of the housing cover; a terminal housing formed of an insulating material and having a terminal receiving chamber, the terminal housing being detachably received in said sleeve of the housing cover; a terminal insertable into the terminal receiving chamber in a direction of a front end of said terminal housing; locking means for locking the terminal in the terminal receiving chamber, said locking means including an inclined hinge portion extending from said front end of said terminal housing toward a rear end thereof and an engagement portion connected to said hinge portion, wherein as said terminal housing is inserted into said inner sleeve, said locking means abuts against said guide slope so that said hinge portion is rotated causing said engagement portion to engage said terminal.
