Abstract
Abstract An electric connector requiring decreased insertion and withdrawal force, even when including groups of 20 to 40 terminals. The connector includes a male portion, a female portion into which the male portion fits, and a cam mechanism. With the cam mechanism, the male casing fitted in a covering portion of the female casing may be slid horizontally between its original fitting position and a male and female terminal contact position, parallel to the fitting surface of the female casing, so as to slide the male and the female terminals out of or into contact with each other with less force than was required previously.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
223 words
In an electric connector comprising a male portion and a female portion, and at least one male terminal with a tab-shaped portion: a female terminal, which is made from a thin metal sheet, said female terminal comprising: an elongate plate member; an electroconductive contact portion disposed at one axial position of said plate member for receiving the tab-shaped portion of said at least one male terminal into said contact portion; and an electrical wire connecting portion disposed at another axial position of said plate member for receiving an electrical wire extending in an axial direction of said plate member; wherein said electroconductive contact portion includes a base portion, first and section side walls at both side edges of said base portion, and an elastic contact part formed by bending at least a portion of said first side wall towards said second side wall in a U shape such that said elastic contact portion is adjacent said second side wall and spaced a predetermined distance therefrom; wherein said tab-like portion is inserted between said elastic contact part and said second side wall in a transverse direction perpendicular to said axial direction such that said tab-like portion of said male terminal extends in said transverse direction; and, wherein the bend formed by bending said first side wall in a U-shape extends in said axial direction.
Claim 2
Dependent Claim
223 words
In an electric connector comprising a male portion and a female portion, and at least one male terminal with a tab-shaped portion: a female terminal, which is made from a thin metal sheet, said female terminal comprising: an elongate plate member; an electroconductive contact portion disposed at one axial position of said plate member for receiving the tab-shaped portion of said at least one male terminal into said contact portion; and an electrical wire connecting portion disposed at another axial position of said plate member for receiving an electrical wire extending in an axial direction of said plate member; wherein said electroconductive contact portion includes a base portion, first and section side walls at both side edges of said base portion, and an elastic contact part formed by bending at least a portion of said first side wall towards said second side wall in a U shape such that said elastic contact portion is adjacent said second side wall and spaced a predetermined distance therefrom; wherein said tab-like portion is inserted between said elastic contact part and said second side wall in a transverse direction perpendicular to said axial direction such that said tab-like portion of said male terminal extends in said transverse direction; and, wherein the bend formed by bending said first side wall in a U-shape extends in said axial direction.
Claim 3
Dependent Claim
119 words
A female terminal according to claim 1, wherein said male terminal is made from a thin metal sheet and includes a second base plate, an electroconductive contact portion at one part of said second base plate, and an electric wire connecting portion at another part of said second base plate; wherein said electroconductive contract portion of said male terminal is formed as said tab-like portion by bending a free side edge part of said second base plate back onto said another part of said second base plate; and said tab-like portion is inserted into the electroconductive contact portion of said female terminal, starting with a part of said tab-like portion located opposite a bent-back part of said tab-like portion.
Claim 4
Dependent Claim
32 words
A female terminal according to claim 1 wherein said predetermined distance is less than a width of said tab-like portion extending in a direction perpendicular to both said transverse and axial directions.
Claim 5
Dependent Claim
20 words
The female terminal according to claim 1, wherein said elastic contact portion is substantially parallel to said second side wall.
