Connector

Claim 2

A connector comprised of a connector housing including first and second chambers, and a terminal which passes through a first aperture provided between said first and second chambers. said terminal comprising a base part having a substantially flat bottom, a tab portion extending from an end of said base part so as to be inserted into said first aperture, a first protrusion protruding upwards from said base part, and a second protrusion protruding downwards from said base part, said first chamber having, an upper wall, and a bottom wall, said bottom wall having a groove for receiving said second protrusion of said terminal therein and a step portion defined by said groove, said step portion having a top surface upon which said second protrusion slides so that said tab portion can be guided into said first aperture.

Claim 3

The connector as set forth in claim 1, wherein said first chamber has a guide wall provided adjacent to said second chamber between said upper wall and said lower wall so that said guide wall and said bottom wall define said first aperture and having a slope facing said bottom wall.

Claim 4

The connector as set forth in claim 2, wherein said step portion is defined so that said second protrusion of said terminal slides upon said top surface of said step portion when said tab portion abuts against guide wall.

Claim 5

The connector as set forth in claim 3, wherein said upper wall has a flexible engaging lance protruding therefrom so as to abut against said terminal and engage said first protrusion.

Claim 6

The connector as set forth in claim 1, wherein said groove has a rectangular cross section.

Claim 7

The connector as set forth in claim 5, wherein said second protrusion has a substantially semi-circular cross section.

Claim 8

The connector as set forth in claim 6, wherein said groove of said first chamber has a depth (H1) and a width (S1), said depth (H1) being longer than a height (H2) of said second protrusion of the terminal, said width (S1) being larger than a radius (S2) of said second protrusion of the terminal and smaller than a width (L) of said tab portion.

Claim 9

The connector as set forth in claim 1, wherein said top surface of said step portion is a part of said bottom wall.

Claim 10

The connector as set forth in claim 8, wherein said first chamber has a guide wall provided adjacent to said second chamber between said upper wall and said lower wall so that said guide wall and said bottom wall define said first aperture and having a slope facing said bottom wall.

Claim 11

The connector as set forth in claim 9, wherein said step portion is defined so that said second protrusion of said terminal slides upon said top surface of said step portion when said tab portion abuts against guide wall.

Claim 12

The connector as set forth in claim 10, wherein said upper wall has a flexible engaging lance protruding therefrom so as to abut against said terminal and engage said first protrusion.

Claim 13

A connector comprised of a connector housing including first and second chambers, and a terminal which passes through a first aperture provided between said first and second chambers, said terminal comprising a base part having a substantially flat bottom, a tab portion extending from an end of said base part so as to be inserted into said first aperture, a first protrusion protruding upwards from said base part, and a second protrusion protruding downwards from said base part, said first chamber having, an upper wall having a flexible engaging lance protruding therefrom so as to abut against said terminal and engage said first protrusion, a bottom wall having a groove and a step portion, and a guide wall being provided adjacent to said second chamber between said upper wall and said lower wall so that said guide wall and said bottom wall define said first aperture and having a slope facing said bottom wall, said groove provided for receiving said second protrusion of said terminal therein and having a rectangular cross section, said step portion defined by said groove and having a top surface upon which said second protrusion slides when said tab portion abuts against guide wall so that said tab portion can be guided into said first aperture.

Claim 14

A connector comprised of a connector housing including first and second chambers, and a terminal which passes through a first aperture provided between said first and second chambers, said terminal comprising a base part having a substantially flat bottom, a tab portion extending from an end of said base part so as to be inserted into said first aperture, a first protrusion protruding upwards from said base part, and a second protrusion protruding downwards from said base part, said first chamber having, an upper wall having a flexible engaging lance protruding therefrom so as to abut against said terminal and engage said first protrusion, a bottom wall having a groove and a step portion, and a guide wall being provided adjacent to said second chamber between said upper wall and said lower wall so that said guide wall and said bottom wall define said first aperture and having a slope facing said bottom wall, said groove provided for receiving said second protrusion of said terminal therein and having a rectangular cross section, said step portion defined by said groove and having a top surface upon which said second protrusion slides when said tab portion abuts against guide wall so that said tab portion can be guided into said first aperture.

Claim 15

The connector as set forth in claim 12, wherein said second protrusion has a substantially semi-circular cross section.

Claim 16

The connector as set forth in claim 13, wherein said groove of said first chamber has a depth (H1) and a width (S1), said depth (H1) being longer than a height (H2) of said second protrusion of the terminal, said width (S1) being larger than a radius (S2) of said second protrusion of the terminal and smaller than a width (L) of said tab portion.
