A connector has a housing ( 10 ) with cavities ( 11 ) for receiving terminal fittings ( 40 ). Locks ( 17 ) lock the terminal fittings ( 40 ) in the cavities ( 11 ) and serve also as partition walls ( 20 ) between cavities ( 11 ) for the miniaturization of the connector. Upside-down insertion preventing portions ( 46 ) are provided on the terminal fittings ( 40 ), but are disposed so as not to interfere with the corresponding lock ( 17 ). The upside-down insertion preventing portions ( 46 ) also do not interfere with the lock ( 17 ) of the adjacent cavity ( 11 ) even if both the upside-down insertion preventing portion ( 46 ) and the lock ( 17 ) are near the front end and are on opposite sides. Since the upside-down insertion preventing portions ( 46 ) and the locks ( 17 ) are near the front end, inserting resistance is low and an earlier detection of upside-down insertion is realized.

1. A connector, comprising:terminal fittings,a housing formed with at least first and second cavities into which the corresponding terminal fittings are insertable, the first cavity having a top wall and first and second side walls, the second cavity having a bottom wall end first and second side walls, a partition wall formed between the cavities, the partition wall including a first deformation preventing wall adjacent the first side walls of the first and second cavities and a second deformation preventing wall adjacent the second side walls of the first and second cavities, the first and second deformation preventing walls being spaced from one another,first and second resiliently deformable locks provided in the respective first and second cavities for engaging and locking the terminal fittings, the second lock being formed unitarily with the partition wall and having a central thick middle disposed between the first and second deformation preventing walls, a first thin portion between the first deformation preventing wall and the second cavity and a second thin portion between the second deformation preventing wall and the second cavity,wherein the second locks forms parts of the partition walls between the first and second cavities. 2. The connector of claim 1, wherein the terminal fittings each are formed with an upside-down insertion-preventing portion disposed for slidable insertion between the first and second deformation preventing walls in a proper rotational orientation of the terminal fitting in the first cavity. 3. The connector of claim 2, wherein the upside-down insertion-preventing portions are at positions so as not to interfere with the locks along an inserting direction of the terminal fittings. 4. The connector of claim 3, wherein each said cavity is formed with a receiving portion for contacting the upside-down insertion-preventing portion when the terminal fitting is inserted upside down and preventing any further insertion of the terminal fitting. 5. The connector of claim 4, wherein each terminal fitting has a tab projecting forward through an opening in a front wall of the corresponding cavity when the terminal fitting is inserted properly. 6. The connector of claim 5, wherein the receiving portion is at a position to contact the upside-down insertion-preventing portion before the front end of the tab strikes the front wall of the cavity. 7. The connector of claim 1, wherein the lock is wider than the terminal fitting. 8. The connector of claim 7, wherein the thin portion projects laterally beyond the terminal fitting. 9. The connector of claim 1, wherein each said cavity comprises a receiving surface arranged substantially normal to an inserting direction of the terminal fitting into the cavity, the terminal fitting at a proper insertion position being prevented from movement in the inserting direction by engagement of the receiving surface with a cooperating portion of the terminal fitting. 10. The connector of claim 1, further comprising a retainer insertable substantially along the inserting direction to doubly lock the terminal fittings in the cavities. 11. A connector, comprising:terminal fittings, each said terminal fitting having opposite front and rear ends, a barrel disposed adjacent said rear end and configured for connection to a wire, a male tab formed adjacent said front end and configured for mating with another terminal fitting, a tubular portion between said barrel and said tab, said tubular portion being formed to define a locking surface and an upside-down insertion-preventing portion substantially opposite said locking surface, said locking surface being closer to said tab than to said barrel and said upside-down insertion-preventing portion being spaced from said tab by a distance no greater than a distance between said locking surface and said tab,a housing formed with a plurality of cavities into which the corresponding terminal fittings are insertable,locks provided in the r espective cavities for engaging and locking the terminal fittings,wherein some locks form at least parts of partition walls between adjacent cavities. 12. The connector of claim 11, wherein the upside-down insertion-preventing portions are at positions so as not to interfere with the locks along an inserting direction of the terminal fittings. 13. The connector of claim 12, wherein each said cavity is formed with a receiving portion for contacting the upside-down insertion-preventing portion when the terminal fitting is inserted upside down and preventing any further insertion of the terminal fitting. 14. The connector of claim 13, wherein the housing has a front wall with openings for receiving the tabs of the respective terminal fittings when the terminal fittings are inserted properly into the cavity. 15. The connector of claim 14, wherein the receiving portion is at a position to contact the upside-down insertion-preventing portion before the front end of the tab strikes the front wall of the cavity.
