Abstract
Abstract Disclosed is a terminal retainer 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 in the completely-connected condition the terminal retainer can be positively engaged with metal terminals. Flexible support pieces for metal terminals are provided on a terminal retainer. A flexible retaining piece for the metal terminal is provided at each terminal receiving chamber. In the provisionally-connected condition of the terminal retainer, the flexible support piece is placed on a push-up projection of the connector housing to be held out of a path of movement of the metal terminal within the terminal receiving chamber. When the terminal retainer shifts to the completely-connected condition, a driven projection on the flexible support piece is engaged in a drive groove in the connector housing to forcibly drive the flexible support piece into engagement with the metal terminal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 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 movable 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, and a flexible retaining piece for retaining said metal terminal is provided at each of said terminal receiving chambers, and wherein said connector housing has a shock absorbing taper surface extending slantwise in a front to rear direction at a rear end portion thereof.
Claim 2
Dependent Claim
102 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 movable 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, and a flexible retaining piece for retaining said metal terminal is provided at each of said terminal receiving chambers, and wherein said connector housing has a shock absorbing taper surface extending slantwise in a front to rear direction at a rear end portion thereof.
Claim 3
Dependent Claim
63 words
A connector as claimed in claim 1, wherein a distal end of the flexible support piece faces said shock absorbing taper surface in said provisionally connected condition, and a distal end of the flexible support piece is brought into contact with said shock absorbing taper surface when said terminal retainer is moved toward the completely-connected condition and when a terminal is incompletely inserted.
Claim 4
Dependent Claim
37 words
A connector as claimed in claim 1, wherein said flexible support piece includes a driven projection and said connector housing has a drive groove provided in a side wall thereof, said projection being guided by said groove.
Claim 5
Dependent Claim
80 words
A connector as claimed in claim 3, 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.
Claim 6
Dependent Claim
122 words
A connector, comprising: a connector housing having a plurality of terminal receiving chambers and a retaining piece extending into each of said receiving chambers; and a terminal retainer attachable to a rear portion of said connector housing and being movable from a provisionally connected condition to a completely connected condition, said terminal retainer including a flexible support piece associated with each of said terminal receiving chambers for retaining metal terminals when said terminal retainer is in said completely connected condition, wherein said connector housing includes deflecting means for deflecting said flexible support pieces outwardly so as to be disposed out of an insertion path of the metal terminals in said receiving chambers when said terminal retainer is in said provisionally connected condition.
Claim 7
Dependent Claim
122 words
A connector, comprising: a connector housing having a plurality of terminal receiving chambers and a retaining piece extending into each of said receiving chambers; and a terminal retainer attachable to a rear portion of said connector housing and being movable from a provisionally connected condition to a completely connected condition, said terminal retainer including a flexible support piece associated with each of said terminal receiving chambers for retaining metal terminals when said terminal retainer is in said completely connected condition, wherein said connector housing includes deflecting means for deflecting said flexible support pieces outwardly so as to be disposed out of an insertion path of the metal terminals in said receiving chambers when said terminal retainer is in said provisionally connected condition.
Claim 8
Dependent Claim
18 words
The connector of claim 5, wherein said housing includes side walls which respectively partially define said receiving chamber.
Claim 9
Dependent Claim
18 words
The connector of claim 6, wherein said deflecting means includes cam projections respectively provided on said side walls.
Claim 10
Dependent Claim
34 words
The connector of claim 5, further comprising means for forcing said flexible support pieces into said insertion path when said terminal retainer is moved from said provisionally connected condition to said completely connected condition.
