Abstract
Abstract An electrical terminal in which a flexible engagement arm of the connector housing is prevented from being deflecting into a concave portion to insure complete insertion of the terminal into the connector housing. The terminal (20) includes an engagement portion with which a forward end (12a) of a flexible engagement arm (12) extending into a terminal reception hole engages when the terminal is inserted into the terminal reception hole, a guide surface (2c) which is formed in front of the engagement concave portion in the insertion direction so that the forward end of the flexible engagement arm (12) comes into sliding contact against the guide surface at the time of insertion, and a concave portion (26) which is formed in the guide surface (2c). The width (b) of the concave portion (26) in the direction perpendicular to the insertion direction is established so as to be smaller than that the width (a) of the forward end (12a) of the flexible engagement arm (12).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
An electric connection terminal comprising: an engagement portion adapted to be engaged by a forward end of a flexible engagement arm formed in a terminal reception hole when said electric connection terminal is inserted into said terminal reception hole; a guide surface formed forwardly of said engagement portion in the insertion direction, said forward end of said flexible engagement arm sliding along said guide surface when the terminal is inserted into the reception hole; and a concave portion formed on said guide surface, the width of said concave portion in the direction perpendicular to said insertion direction being smaller than the width of said forward end of said flexible engagement arm so that said forward end does not deflect into said concave portion.
Claim 2
Dependent Claim
123 words
An electric connection terminal comprising: an engagement portion adapted to be engaged by a forward end of a flexible engagement arm formed in a terminal reception hole when said electric connection terminal is inserted into said terminal reception hole; a guide surface formed forwardly of said engagement portion in the insertion direction, said forward end of said flexible engagement arm sliding along said guide surface when the terminal is inserted into the reception hole; and a concave portion formed on said guide surface, the width of said concave portion in the direction perpendicular to said insertion direction being smaller than the width of said forward end of said flexible engagement arm so that said forward end does not deflect into said concave portion.
Claim 3
Dependent Claim
39 words
The electric connection terminal of claim 1, wherein said concave portion includes a pair of concave sections disposed adjacent each other and defining a deflecting preventing portion therebetween along which said forward end slides during insertion of said terminal.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
50 words
The electric connection terminal of claim 4, wherein said guide surface is provided on an outer surface of a cylindrical box portion of said terminal in which an associated male terminal is receive and wherein said concave portion is embossed on an inside surface thereof which contacts said male terminal.
Claim 8
Dependent Claim
103 words
An electric connection terminal comprising: an engagement portion adapted to be engaged by a forward end of a flexible engagement arm formed in a terminal reception hole when said electric connection terminal is inserted into said terminal reception hole; a guide surface formed forwardly of said engagement portion in the insertion direction, said forward end of said flexible engagement arm sliding along said guide surface when the terminal is inserted into the reception hole; and a plurality of concave portions formed on said guide surface and defining a deflecting preventing portion therebetween along which said forward end slides during insertion of said terminal.
Claim 9
Dependent Claim
103 words
An electric connection terminal comprising: an engagement portion adapted to be engaged by a forward end of a flexible engagement arm formed in a terminal reception hole when said electric connection terminal is inserted into said terminal reception hole; a guide surface formed forwardly of said engagement portion in the insertion direction, said forward end of said flexible engagement arm sliding along said guide surface when the terminal is inserted into the reception hole; and a plurality of concave portions formed on said guide surface and defining a deflecting preventing portion therebetween along which said forward end slides during insertion of said terminal.
Claim 10
Dependent Claim
50 words
The electric connection terminal of claim 6, wherein said guide surface is provided on an outer surface of a cylindrical box portion of said terminal in which an associated male terminal is receive and wherein said concave portion is embossed on an inside surface thereof which contacts said male terminal.
Claim 11
Dependent Claim
46 words
The terminal of claim 6, wherein the width of said concave portions in the direction perpendicular to said insertion direction are smaller than the width of said forward end of said flexible engagement arm so that said forward end does not deflect into said concave portion.
Claim 12
Dependent Claim
121 words
An electric connection terminal comprising: an engagement portion adapted to be engaged by a forward end of a flexible engagement arm formed in a terminal reception hole when said electric connection terminal is inserted into said terminal reception hole in an insertion direction, said forward end having a predetermined length in said insertion direction; a guide surface formed forwardly of said engagement concave portion in the insertion direction, said flexible engagement arm sliding along said guide surface when said terminal is inserted into said reception hole; and a concave portion formed on said guide surface having a length in said insertion direction smaller than said predetermined length of said forward end so that said forward end does not become engaged therein.
