Abstract
Abstract A terminal retaining structure for a connector in which a terminal retaining member (2) is allowed to enter into a connector housing (3) from an opening (6) facing a terminal accommodating chamber of the connector housing. The terminal retaining member has a terminal retaining projection (13) in the front thereof and a notched stepped portion (14) in the rear thereof. In such terminal retaining structure, a primary temporary retaining projection (15) and a secondary temporary retaining projection (16) are arranged on an overhang wall portion (12) so as to be staggered in a terminal retaining member insertion direction. The overhang wall portion has the terminal retaining projection (13) of the terminal retaining member (2) projected therefrom. The primary temporary retaining projection (15) and the secondary temporary retaining projection (16) are engageable with the side end edges of the opening sequentially. The notched stepped portion (14) is brought into contact with and supported on an outer housing wall (9) after the secondary temporary retaining projection (16) has passed by the corresponding side end edge of the opening (6). As a result, the terminal retaining projection (13) is allowed to enter obliquely into the opening to come in contact with the inner housing wall.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
196 words
A connector comprising: a connector housing a terminal receiving chamber, an external wall of said including an opening therein which communicates with said terminal receiving chamber, said opening being at least partially defined by a projecting wall; and a rear holder secured to said connector housing and being moveable from a temporarily retained position, at which a terminal is insertable into said receiving chamber, to a completely retained position, at which said terminal is retained in said housing by said rear holder, said rear holder including a terminal retaining projection extend in a forward direction which abuts against said terminal when said rear holder is in said completely retained position, and first and second retaining projections provided on said terminal retaining projection for retaining said rear holder in said temporarily retained position, said first and second retaining projections being vertically offset from each other such that when said holder is in said temporarily retained position, said first retaining projection is on an outside of said opening abutting against an outside surface of said projecting wall and said second retaining projection is on an inside of said opening abutting against an inside surface of said projecting wall.
Claim 2
Dependent Claim
196 words
A connector comprising: a connector housing a terminal receiving chamber, an external wall of said including an opening therein which communicates with said terminal receiving chamber, said opening being at least partially defined by a projecting wall; and a rear holder secured to said connector housing and being moveable from a temporarily retained position, at which a terminal is insertable into said receiving chamber, to a completely retained position, at which said terminal is retained in said housing by said rear holder, said rear holder including a terminal retaining projection extend in a forward direction which abuts against said terminal when said rear holder is in said completely retained position, and first and second retaining projections provided on said terminal retaining projection for retaining said rear holder in said temporarily retained position, said first and second retaining projections being vertically offset from each other such that when said holder is in said temporarily retained position, said first retaining projection is on an outside of said opening abutting against an outside surface of said projecting wall and said second retaining projection is on an inside of said opening abutting against an inside surface of said projecting wall.
Claim 3
Dependent Claim
15 words
The connector of claim 1, wherein said first and second retaining projections have triangular cross-section.
Claim 4
Dependent Claim
32 words
The connector of claim 1, wherein said rear holder is moved from said temporarily retained position to said completely retained by obliquely orienting said rear holder with respect to said connector housing.
Claim 5
Dependent Claim
28 words
The connector of claim 1, wherein when said rear holder is in said completely retained position said terminal retaining projection contacts an inner surface of said connector housing.
Claim 6
Dependent Claim
29 words
The connector of claim 1, wherein said connector housing has a plurality of said terminal accommodating chambers and said rear holder includes a corresponding number of terminal retaining projections.
Claim 7
Dependent Claim
28 words
The connector of claim 1, where the vertical distance between said first and second retaining projections is at least as large as the thickness of said projecting wall.
Claim 8
Dependent Claim
209 words
A connector, comprising: a connector housing having a terminal receiving chamber, an external wall of said housing including an opening therein which communicates with said terminal receiving chamber, said opening being at least partially defined by a projecting wall; and a rear holder secured said connector housing and being moveable from a temporarily retained position, at which a terminal is insertable into said terminal receiving chamber, to a completely retained position, at which said terminal is retained in said housing by said rear holder, said rear holder including a terminal retaining projection extending in a forward direction which abuts against said terminal when said rear holder is in said completely retained position, and first and second retaining projections for retaining said rear holder in said temporarily retained position, said first and second retaining projections being vertically offset from each other such that when said rear holder is in said temporarily retained position, said first retaining projection is on an outside of said opening abutting against an outside surface of said projecting wall and said second retaining projection is on an inside of said opening abutting against an inside surface of said projecting wall, wherein said first and second retaining projections are offset in an insertion direction of said terminal.
Claim 9
Dependent Claim
209 words
A connector, comprising: a connector housing having a terminal receiving chamber, an external wall of said housing including an opening therein which communicates with said terminal receiving chamber, said opening being at least partially defined by a projecting wall; and a rear holder secured said connector housing and being moveable from a temporarily retained position, at which a terminal is insertable into said terminal receiving chamber, to a completely retained position, at which said terminal is retained in said housing by said rear holder, said rear holder including a terminal retaining projection extending in a forward direction which abuts against said terminal when said rear holder is in said completely retained position, and first and second retaining projections for retaining said rear holder in said temporarily retained position, said first and second retaining projections being vertically offset from each other such that when said rear holder is in said temporarily retained position, said first retaining projection is on an outside of said opening abutting against an outside surface of said projecting wall and said second retaining projection is on an inside of said opening abutting against an inside surface of said projecting wall, wherein said first and second retaining projections are offset in an insertion direction of said terminal.
Claim 10
Dependent Claim
34 words
The connector of claim 1, wherein said rear holder further includes a final retaining projection which abuts against an inside surface of said connector housing when said terminal is in said completely retained position.
Claim 11
Dependent Claim
26 words
The connector of claim 8, wherein said final retaining projection includes an inside surface to allow said final retaining projection to pass by said projecting wall.
Claim 12
Dependent Claim
21 words
The connector of claim 9, wherein said first and second retaining projections are respectively on opposite sides of said retaining projection.
Claim 13
Dependent Claim
19 words
The connector of claim 10, wherein said final retaining projection extends from a rear side of said rear holder.
Claim 14
Dependent Claim
41 words
The connector of claim 7, wherein said rear holder includes a notched portion at a rear end thereof which defines a contact surface which contacts an exterior surface of said connector housing when said holder is in said temporarily retained position.
Claim 15
Dependent Claim
