Abstract
Abstract A connector with a terminal retainer in which when a metal terminal is to be detached by moving a flexible deformable plate of a terminal retainer, excessive deflection of the flexible deformable plate is prevented. A terminal retainer is connected to a connector housing in a two-stage manner, that is, first in a provisionally-connected condition and then in a completely-connected condition. In the provisionally-connected condition, a flexible deformable plate of the terminal retainer rests on push-up projections to enable the insertion of a metal terminal. In this condition, when the flexible deformable plate is to be deflected outwardly, the flexible deformable plate abuts against an excessive deflection-preventing portion, and is prevented from being damaged.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A connector comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates being deflected to allow an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition, said deflection of each of said deformable plates for permitting withdrawal of said corresponding metal terminal being caused by an external jig inserted into said terminal holder; and means for preventing an excessive deflection of each of said flexible deformable plates by said jig.
Claim 2
Dependent Claim
133 words
A connector comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates being deflected to allow an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition, said deflection of each of said deformable plates for permitting withdrawal of said corresponding metal terminal being caused by an external jig inserted into said terminal holder; and means for preventing an excessive deflection of each of said flexible deformable plates by said jig.
Claim 3
Dependent Claim
92 words
A connector according to claim 1, wherein said terminal retainer and said connector housing have an insertion path along which said metal terminal is inserted and said terminal holder has a plurality of relief notches, and wherein each of said terminal retaining members is disposed out of said insertion path in the provisionally connected condition, and each of said push-up projections is engaged with said relief notch so that each of said flexible deformable plates is restored to a non-deflected condition to bring said terminal retaining member deep into said connector housing.
Claim 4
Dependent Claim
38 words
A connector according to claim 1, wherein said preventing means includes a plurality of excessive deflection-preventing plates; and each of said flexible deformable plates abuts against said excessive deflectionpreventing plate when said flexible deformable plates is excessively deflected.
Claim 5
Dependent Claim
16 words
A connector according to claim 3, wherein said preventing means is integral to said connector housing.
Claim 6
Dependent Claim
16 words
A connector according to claim 3, wherein said preventing means is integral to said terminal retainer.
Claim 7
Dependent Claim
21 words
A connector according to claim 5, wherein each of said excessive deflection-preventing plates is disposed outside of said flexible deformable plate.
Claim 8
Dependent Claim
128 words
A connector, comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates allowing an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition; and means for preventing an excessive deflection of each of said flexible deformable plates, wherein said connector housing includes an enclosure frame disposed around an outer periphery of a rear end thereof, said excessive deflection-preventing plates being integral to said enclosure frame.
Claim 9
Dependent Claim
128 words
A connector, comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates allowing an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition; and means for preventing an excessive deflection of each of said flexible deformable plates, wherein said connector housing includes an enclosure frame disposed around an outer periphery of a rear end thereof, said excessive deflection-preventing plates being integral to said enclosure frame.
Claim 10
Dependent Claim
134 words
A connector, comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates allowing an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition; and means for preventing an excessive deflection of each of said flexible deformable plates, wherein said connector housing includes a plurality of push-up projections; and said flexible deformable plates respectively rest on said push-up projections for allowing insertion and withdrawal of said metal terminals in the provisionally-connected condition.
Claim 11
Dependent Claim
134 words
A connector, comprising: a plurality of metal terminals; a connector housing for receiving said metal terminals therein; a terminal holder movably engaged with said connector housing in two steps, provisionally and completely, said terminal holder including a plurality of flexible deformable plates each of which has a terminal retaining member, each of said flexible deformable plates allowing an insertion and withdrawal of a corresponding metal terminal in the provisionally-connected condition, and said terminal retaining member urging and fixing said corresponding metal terminal in the completely-connected condition; and means for preventing an excessive deflection of each of said flexible deformable plates, wherein said connector housing includes a plurality of push-up projections; and said flexible deformable plates respectively rest on said push-up projections for allowing insertion and withdrawal of said metal terminals in the provisionally-connected condition.
