Abstract
Abstract A terminal position assurance system is provided for an electrical connector which includes a dielectric housing having a terminal-receiving passage into which a terminal is inserted in an insertion direction to a fully inserted position. A latch surface is formed in the housing adjacent the passage and facing in the insertion direction. A bendable tab is provided on the terminal and is adapted to be bent against the latch surface. The bendable tab is structured to be bent about an axis generally parallel to the insertion direction to move an edge portion of the tab to a position over the latch surface when the terminal is in its fully inserted position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
A terminal position assurance system in an electrical connector which includes a dielectric housing having a wall with a terminal-receiving passage therethrough, the wall defining first and second surfaces, a terminal adapted to be received in the passage with a mating portion on one side of the wall and a terminating portion on the other side of the wall, stop means on the terminal for engaging a stop surface of the housing to prevent the terminal from passing completely through the passage in an insertion direction toward the first surface and to define a fully inserted position of the terminal, and a bendable tab on the terminal and adapted to be bent against the second surface of the wall when the terminal is inserted into the passage, wherein the improvement comprises said mating terminal portion having a forward end, said stop means located at said forward end and said bendable tab located at said forward end being structured to be bent about an axis perpendicular to the second surface of the wall and be positioned over the second surface when the terminal is fully positioned in the passage.
Claim 2
Dependent Claim
188 words
A terminal position assurance system in an electrical connector which includes a dielectric housing having a wall with a terminal-receiving passage therethrough, the wall defining first and second surfaces, a terminal adapted to be received in the passage with a mating portion on one side of the wall and a terminating portion on the other side of the wall, stop means on the terminal for engaging a stop surface of the housing to prevent the terminal from passing completely through the passage in an insertion direction toward the first surface and to define a fully inserted position of the terminal, and a bendable tab on the terminal and adapted to be bent against the second surface of the wall when the terminal is inserted into the passage, wherein the improvement comprises said mating terminal portion having a forward end, said stop means located at said forward end and said bendable tab located at said forward end being structured to be bent about an axis perpendicular to the second surface of the wall and be positioned over the second surface when the terminal is fully positioned in the passage.
Claim 3
Dependent Claim
24 words
The terminal position assurance system as set forth in claim 1, wherein said second surface is generally flat and said tab is generally planar.
Claim 4
Dependent Claim
38 words
The terminal position assurance system as set forth in claim 2, wherein said tab had an edge generally perpendicular to said axis and adapted for lockingly engaging the second surface when the tab is bent about the axis.
Claim 5
Dependent Claim
31 words
The terminal position assurance system as set forth in claim 1, wherein said terminal mating portion is female forming a generally rectangular cross section adapted to receive a male blade terminal.
Claim 6
Dependent Claim
77 words
The terminal position assurance system as set forth in claim 4 wherein said terminal mating portion includes a base wall having two edges each extending along a line parallel to the terminal insertion direction, two side walls bent at the base wall edges extending in the same direction and perpendicular to the base and two top walls bent from the side walls extending toward each other where said bendable tab extends from one of said top walls.
Claim 7
Dependent Claim
120 words
A terminal position assurance system in an electrical connector which includes a dielectric housing having a terminal-receiving passage into which a terminal having a forward end is inserted in an insertion direction with its forward end first to a fully inserted position, a latch surface adjacent the passage facing in said insertion direction, and a bendable tab on the terminal and adapted to be bent against the latch surface, wherein the improvement comprises said bendable tab located at said forward end and being structured to be bent about an axis generally parallel to said insertion direction to move an edge portion of the tab to a position over the latch surface when the terminal is in its fully inserted position.
Claim 8
Dependent Claim
120 words
A terminal position assurance system in an electrical connector which includes a dielectric housing having a terminal-receiving passage into which a terminal having a forward end is inserted in an insertion direction with its forward end first to a fully inserted position, a latch surface adjacent the passage facing in said insertion direction, and a bendable tab on the terminal and adapted to be bent against the latch surface, wherein the improvement comprises said bendable tab located at said forward end and being structured to be bent about an axis generally parallel to said insertion direction to move an edge portion of the tab to a position over the latch surface when the terminal is in its fully inserted position.
Claim 9
Dependent Claim
24 words
The terminal position assurance system as set forth in claim 6, wherein said latch surface is generally flat and said tab is generally planar.
Claim 10
Dependent Claim
38 words
The terminal position assurance system as set forth in claim 7, wherein said tab had an edge generally perpendicular to said axis and adapted for lockingly engaging the latch surface when the tab is bent about the axis.
Claim 11
Independent Claim
172 words
A method of ensuring proper positioning of a female terminal having a generally rectangular cross section defining a terminal mating cavity having a longitudinal axis in a dielectric housing of an electrical connector, the housing having a terminal-receiving passage into which the terminal is inserted in an insertion direction to a fully inserted position, comprising the steps of: providing a latch surface on the housing adjacent the passage and facing in said insertion direction; providing a bendable tab on the terminal, the tab being bendable about an axis generally parallel to said insertion direction from a first position aligned with said passage to a second position over the latch surface; inserting the terminal into the passage in said insertion direction to said fully inserted position; inserting an elongated blade like tool into said terminal mating cavity; and bending said tab from said first position to said second position by moving the tool about its longitudinal axis generally while the tool axis is congruent with the longitudinal axis of the terminal mating cavity.
