Abstract

A connector housing is provided capable of reliably preventing a terminal fitting from being inserted and accommodated in a vertically inverted posture into a cavity. A connector housing includes a cavity capable of accommodating a terminal fitting provided with a projection on an outer side surface of a terminal main body portion in the form of a rectangular tube. The cavity includes a main body accommodating portion into which the terminal main body portion is to be accommodated and a groove portion into which the projection is insertable and movable forward when the terminal fitting is inserted in a proper posture into the cavity. A guiding portion for angularly displacing the terminal main body portion by coming into contact with the projection when the terminal fitting is inserted in a vertically inverted posture into the cavity is provided on a side of the cavity before the main body accommodating portion.

First claim

What is claimed is:

1 . A connector housing ( 10 ) having a cavity ( 11 ) configured to accommodate a terminal fitting ( 20 ) inserted in an inserting direction, the terminal fitting ( 20 ) having a terminal main body portion ( 21 ) provided with a projection ( 22 ) on an outer side surface thereof the connector housing ( 10 ) comprising:
a main body accommodating portion ( 13 ) formed in the cavity ( 11 ) into which the terminal main body portion ( 21 ) is to be accommodated; a groove portion ( 17 ) formed in the cavity ( 11 ) into which the projection ( 22 ) is insertable and movable forward when the terminal fitting ( 20 ) is inserted in a proper posture into the cavity ( 11 ); and a guiding portion ( 18 ) provided on a side of the cavity ( 11 ) rearward of the main body accommodating portion ( 13 ) in the insertion direction for angularly displacing the terminal main body portion ( 21 ) by coming into contact with the projection ( 22 ) when the terminal fitting ( 20 ) is inserted in a vertically inverted posture into the cavity ( 11 ).

2 . The connector housing ( 10 ) of claim 1 , wherein the guiding portion ( 18 ) is a projection having an inclined surface ( 18 F, 18 S).

3 . The connector housing ( 10 ) of claim 1 , wherein the main body accommodating portion ( 13 ) has a substantially rectangular cross section, and further comprising:
a plug accommodating portion ( 14 ) for accommodating a plug (G) formed on the terminal fitting ( 20 ) rearward of the main body accommodating portion ( 21 ) in the insertion direction, the plug accommodating portion ( 14 ) having a substantially circular cross-section; and a cross-section changing portion ( 15 ) between the plug accommodating portion ( 14 ) and the main body accommodating portion ( 13 ), the cross-section changing portion ( 15 ) having an inclined surface ( 15 K) inclined in the insertion direction from the rubber plug accommodating ( 14 ) portion for changing the cross-section of the cavity ( 11 ) from the substantially circular cross-section of the plug accommodating portion ( 14 ) to the substantially rectangular cross-section of the main body accommodating portion ( 13 ) and for narrowing a width of the cavity ( 11 ).

4 . The connector housing ( 10 ) of claim 3 , wherein the guiding portion ( 18 ) is a projection formed in a range from a front end part of the rubber plug accommodating portion ( 14 ) to the front end of the cross-section changing portion ( 15 ).

5 . The connector housing ( 10 ) of claim 1 , further comprising a second groove portion ( 16 ) formed in a surface of the cavity ( 11 ) for accommodating a stabilizer ( 26 ) formed on a surface of the terminal fitting ( 20 ).

6 . The connector housing ( 10 ) of claim 1 , wherein the guiding portion ( 18 ) includes upper and lower first inclined guiding surfaces ( 18 F) inclined in the inserting direction and inclined to widen a space therebetween in the inserting direction, and
a second inclined surface ( 18 S) rearward of the upper and lower first inclined guiding surfaces ( 18 F) and inclined in the inserting direction, the second inclined surface ( 18 S) configured to contact the projection ( 22 ) when the terminal fitting ( 20 ) is inserted into the cavity ( 11 ) in the vertically inverted posture.

7 . The connector housing ( 10 ) of claim 6 , wherein the upper and lower first inclined guiding surfaces ( 18 F) guide the projecting ( 22 ) upwardly or downwardly, respectively and angularly displace the terminal fitting ( 20 ) to prevent insertion of the terminal fitting ( 20 ) in the cavity ( 11 ) in the vertically inverted posture.

8 . The connector housing ( 10 ) of claim 6 , wherein the inclined surface ( 15 K) of the cross-section changing portion ( 15 ) contacts the angularly displaced terminal fitting ( 20 ) inserted in the vertically inverted posture to prevent further insertion in the inserting direction.

9 . A connector for receiving at least one terminal fitting ( 20 ), the at least one terminal fitting ( 20 ) having a main body portion ( 21 ) with a projection ( 22 ) projecting from an outer surface thereof, and a plug (G) provided on the terminal fitting ( 20 ) rearward of the main body portion ( 21 ), the connector comprising:
a connector housing ( 10 ); at least one cavity ( 11 ) formed in the connector housing ( 10 ) for accommodating the at least one terminal fitting ( 20 ) inserted into the cavity ( 11 ) in an inserting direction; a main body accommodating portion ( 13 ) formed in the cavity ( 11 ), the main body accommodating portion ( 13 ) having a substantially rectangular cross-section and a main body accommodating portion ( 13 ) width dimension; a plug accommodating portion ( 14 ) formed in the cavity ( 11 ) rearward of the main body accommodating portion ( 13 ) in the inserting direction, the plug accommodating portion ( 13 ) having a substantially circular cross-section and a width dimension larger than the main body accommodating portion ( 13 ) width direction; a cross-section changing portion ( 15 ) between the plug accommodating portion ( 14 ) and the main body accommodating portion ( 13 ), the cross-section changing portion ( 15 ) having an inclined surface ( 15 K) inclined rearward from the plug accommodating portion ( 14 ) for changing the cross-section of the cavity ( 11 ) from the substantially circular cross-section of the plug accommodating portion ( 14 ) to the substantially rectangular cross-section of the main body accommodating portion ( 13 ) and for narrowing a width of the cavity ( 11 ); a groove portion ( 17 ) formed in the main body accommodating portion ( 13 ) for receiving the projection ( 22 ) when the terminal fitting ( 20 ) is inserted in a proper posture into the cavity ( 11 ); and a guiding portion ( 18 ) formed on a side of the cavity ( 11 ) rearward of the main body accommodating portion ( 13 ) in the insertion direction for contacting the projection ( 22 ) and angularly displacing the terminal main body portion ( 21 ) when the terminal fitting ( 20 ) is inserted in a vertically inverted posture into the cavity ( 11 ).

10 . The connector of claim 9 , wherein the guiding portion ( 18 ) is a projection having at least one inclined surface ( 18 F, 18 S).

11 . The connector of claim 9 , wherein the guiding portion ( 18 ) is a projection formed in a range from a front end part of the rubber plug accommodating ( 14 ) portion to the front end of the cross-section changing portion ( 15 ).

12 . The connector of claim 9 , further comprising a second groove portion ( 16 ) formed in a surface of the cavity ( 11 ) for accommodating a stabilizer ( 26 ) formed on a surface of the terminal fitting ( 20 ).

13 . The connector of claim 9 , wherein the guiding portion ( 18 ) includes upper and lower first inclined guiding surfaces ( 18 F) inclined in an inserting direction of the terminal fitting and inclined to widen a space therebetween in the inserting direction, and
a second inclined surface ( 18 S) rearward of the upper and lower first inclined guiding surfaces ( 18 F) and inclined in the inserting direction, the second inclined surface ( 18 S) configured to contact the projection ( 22 ) when the terminal fitting ( 20 ) is inserted into the cavity ( 11 ) in the vertically inverted posture.

14 . The connector of claim 13 , wherein the upper and lower first inclined guiding surfaces ( 18 F) guide the projecting ( 22 ) upwardly or downwardly and angularly displace the terminal fitting ( 20 ) to prevent insertion of the terminal fitting ( 20 ) in the cavity ( 11 ) in the vertically inverted posture.

15 . The connector of claim 9 , whe
