Abstract
Abstract A tubular extension portion is extended from an edge portion of a retainer mounting a hole at an upper surface of a connector housing. A retainer has a flange. When the retainer is fitted in the retainer mounting hole, the flange is abutted against an upper end of the tubular extension portion, so that the retainer mounting hole is closed similar to a lid to prevent water or the like from intruding into the retainer mounting hole from the upper surface of a connector. Water, dropping from above the retainer mounting hole, falls on the upper surface of the retainer and the flange, and flows to the upper surface of the connector housing across an outer peripheral edge of the flange. Therefore, the water will not intrude into a gap between the retainer and the retainer mounting hole. Also, because the water on the upper surface of the connector housing cannot flow up and over the tubular extension portion, water also will not flow into the retainer mounting hole from here.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
117 words
A retainer mounting structure of a connector comprising: a connector having metal terminals inserted respectively in cavities in said connector in a longitudinal direction, a retainer mounting hole in communication with said cavities extending inwardly from an outer surface of said connector in a direction normal to said longitudinal direction, an open end of said retainer mounting hole extending from the outer surface of said connector to form an extension portion, and a retainer for retaining said metal terminals against withdrawal is fitted in said retainer mounting hole, said retainer having a flange that is abutted against the open end of the extension portion of said retainer mounting hole to close and seal said retainer mounting hole.
Claim 2
Dependent Claim
117 words
A retainer mounting structure of a connector comprising: a connector having metal terminals inserted respectively in cavities in said connector in a longitudinal direction, a retainer mounting hole in communication with said cavities extending inwardly from an outer surface of said connector in a direction normal to said longitudinal direction, an open end of said retainer mounting hole extending from the outer surface of said connector to form an extension portion, and a retainer for retaining said metal terminals against withdrawal is fitted in said retainer mounting hole, said retainer having a flange that is abutted against the open end of the extension portion of said retainer mounting hole to close and seal said retainer mounting hole.
Claim 3
Dependent Claim
50 words
A retainer mounting structure of a connector according to claim 1, in which a thickness of two opposing sides of said extension portion is different, and an angled portion is formed on a peripheral edge of said flange and engages with an outer peripheral side surface of said extension portion.
Claim 4
Dependent Claim
41 words
A retainer mounting structure of a connector according to claim 1, in which a jig engagement portion sized to engage with a retainer removal jig is formed in an outer periphery of said retainer between said flange and said extension portion.
Claim 5
Dependent Claim
148 words
A connector and retainer mounting structure comprising: a connector mounted in a predetermined position to define an upper surface of said connector; at least one cavity formed in said connector for receiving a terminal in a longitudinal direction; a retainer mounting hole formed in the upper surface of said connector and extending inwardly from the upper surface in a direction normal to said longitudinal direction to communicate with said at least one cavity, said retainer mounting hole including an extension portion extending outwardly above said upper surface and defining extending peripheral sides having peripheral side surfaces, vertical inner walls, and an open end; a retainer for retaining said terminal against withdrawal, said retainer being fitted in said retainer mounting hole, said retainer including a flange that closes and seals the vertical inner walls of said retainer mounting hole by abutting against the open end of said extension portion.
Claim 6
Dependent Claim
148 words
A connector and retainer mounting structure comprising: a connector mounted in a predetermined position to define an upper surface of said connector; at least one cavity formed in said connector for receiving a terminal in a longitudinal direction; a retainer mounting hole formed in the upper surface of said connector and extending inwardly from the upper surface in a direction normal to said longitudinal direction to communicate with said at least one cavity, said retainer mounting hole including an extension portion extending outwardly above said upper surface and defining extending peripheral sides having peripheral side surfaces, vertical inner walls, and an open end; a retainer for retaining said terminal against withdrawal, said retainer being fitted in said retainer mounting hole, said retainer including a flange that closes and seals the vertical inner walls of said retainer mounting hole by abutting against the open end of said extension portion.
Claim 7
Dependent Claim
32 words
The connector and retainer mounting structure of claim 4, wherein said flange includes an angled portion that extends inward toward said connector and engages at least one of said extending peripheral sides.
Claim 8
Dependent Claim
56 words
The connector and retainer mounting structure of claim 5, wherein thicknesses of two opposing extending sides of said extension portion are different, one of said two opposing sides being too thick to allow engagement of said angled portion with said corresponding peripheral side surface such that said retainer can only be fitted in one proper orientation.
Claim 9
Dependent Claim
38 words
The connector and retainer mounting structure of claim 4, wherein said flange includes a fitting portion extending inwardly toward said connector around an entire periphery of said flange for engaging said peripheral side surfaces of said extension portion.
Claim 10
Dependent Claim
166 words
A connector and retainer mounting structure comprising: a connector mounted in a predetermined to define an upper surface of said connector; at least one cavity formed in said connector for receiving a terminal in a longitudinal direction; a retainer mounting hole formed in the upper surface of said connector and extending inwardly from the upper surface in a direction normal to the longitudinal direction to communicate with said at least one cavity, said retainer mounting hole including an extension portion extending outwardly above said upper surface and defining extending peripheral sides having peripheral side surfaces, vertical inner walls, and an open end; a retainer for retaining said terminal against withdrawal, said retainer being fitted in said retainer mounting hole and defining a vertical gap between said vertical inner walls of said extension portion and said retainer, said retainer including a flange having peripheral dimensions that close and seal the vertical gap and abut said open end of said tubular extension portion and form a horizontal gap.
Claim 11
Dependent Claim
166 words
A connector and retainer mounting structure comprising: a connector mounted in a predetermined to define an upper surface of said connector; at least one cavity formed in said connector for receiving a terminal in a longitudinal direction; a retainer mounting hole formed in the upper surface of said connector and extending inwardly from the upper surface in a direction normal to the longitudinal direction to communicate with said at least one cavity, said retainer mounting hole including an extension portion extending outwardly above said upper surface and defining extending peripheral sides having peripheral side surfaces, vertical inner walls, and an open end; a retainer for retaining said terminal against withdrawal, said retainer being fitted in said retainer mounting hole and defining a vertical gap between said vertical inner walls of said extension portion and said retainer, said retainer including a flange having peripheral dimensions that close and seal the vertical gap and abut said open end of said tubular extension portion and form a horizontal gap.
Claim 12
Dependent Claim
