Abstract
Abstract In the present invention, a terminal retainer is mounted on a rear portion of a connector housing so as to move in a two-stage manner, that is, between a provisionally-connected condition and a completely-connected condition, and a metal terminal can be immediately withdrawn in the provisionally-connected condition and can be positively engaged with metal terminals. According to the present invention, flexible support pieces each having a terminal retaining projection having a tapered relief engagement surface for a metal terminal are provided on a terminal retainer. A provisionally-retaining projection for provisionally retaining the terminal retainer is provided at a connector housing. In the provisionally-connected condition of the terminal retainer, by pulling the metal terminal, the terminal retainer is retracted via the tapered relief engagement surfaces, and at the same time the flexible support piece is caused to slide onto the retaining projection to be disposed out of the path of movement of the metal terminal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces each having a terminal retaining projection for retaining a metal terminal and said connector housing includes a provisionally retaining projection for provisionally retaining said terminal retainer, said terminal retaining projection having a tapered flank engagement surface.
Claim 2
Dependent Claim
85 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces each having a terminal retaining projection for retaining a metal terminal and said connector housing includes a provisionally retaining projection for provisionally retaining said terminal retainer, said terminal retaining projection having a tapered flank engagement surface.
Claim 3
Dependent Claim
51 words
A connector as claimed in claim 1, wherein said terminal retainer is retracted through said tapered flank engagement surface by pulling said metal terminal with said flexible support piece being caused to slide onto said provisionally retaining projection to be disposed out of a path of movement of said metal terminal.
Claim 4
Dependent Claim
150 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces each having a terminal retaining projection for retaining a metal terminal and said connector housing includes a provisionally retaining projection for provisionally retaining said terminal retainer, and wherein when said terminal retainer is further moved rearwardly from said provisionally connected condition, said flexible support piece slides onto said provisionally retaining projection to be disposed out of a path of movement of said metal terminal and a retaining projection on said terminal retainer is engaged with a withdrawal prevention projection on said connector housing after said retaining projection, formed on said terminal retainer, slides past an engagement portion of said connector housing.
Claim 5
Dependent Claim
150 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces each having a terminal retaining projection for retaining a metal terminal and said connector housing includes a provisionally retaining projection for provisionally retaining said terminal retainer, and wherein when said terminal retainer is further moved rearwardly from said provisionally connected condition, said flexible support piece slides onto said provisionally retaining projection to be disposed out of a path of movement of said metal terminal and a retaining projection on said terminal retainer is engaged with a withdrawal prevention projection on said connector housing after said retaining projection, formed on said terminal retainer, slides past an engagement portion of said connector housing.
Claim 6
Dependent Claim
113 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces for retaining metal terminals in said completely connected condition, wherein a flexible retaining piece for retaining said metal terminal is provided in each of said terminal receiving chambers, and wherein said flexible support piece includes a driven projection and said connector housing has a drive groove provided in a wall of each of said terminal receiving chambers, said projection being guided by said groove.
Claim 7
Dependent Claim
113 words
A connector comprising: a connector housing having a plurality of terminal receiving chambers; and a terminal retainer mounted on a rear portion of said connector housing so as to be moveable between a provisionally connected condition and a completely connected condition, wherein said terminal retainer includes flexible support pieces for retaining metal terminals in said completely connected condition, wherein a flexible retaining piece for retaining said metal terminal is provided in each of said terminal receiving chambers, and wherein said flexible support piece includes a driven projection and said connector housing has a drive groove provided in a wall of each of said terminal receiving chambers, said projection being guided by said groove.
Claim 8
Dependent Claim
81 words
A connector as claimed in claim 4, wherein said flexible support piece is disposed on a push-up projection of said connector housing to be held out of a path of movement of said metal terminal within said terminal receiving chamber in said provisionally connected condition, and wherein when said terminal retainer shifts to said completely connected condition, said flexible support piece is forced into engagement with said metal terminal due to the engagement of said driven projection in said drive groove.
