Abstract

A connector includes a first housing (10) and a second housing (60) connectable to each other. The second housing (60) includes two walls (64) facing each other. The first housing (10) includes a receptacle (12) defining a fitting space (14), two side walls (19) connected to both circumferential ends of the receptacle (12) and a lock arm (24) arranged between the side walls (19). Entrance spaces (29) into which the walls (64) enter are defined between the side walls (19) and the lock arm (24) to communicate with the fitting space (14). Protrusions (31, 32) configured to contact the walls (64) are provided on inner surfaces of the side walls (19).

First claim

What is claimed is:

1 . A connector with a first housing ( 10 ) to be connected to a second housing ( 60 ), the second housing ( 60 ) having a tube ( 61 ) and at least one wall ( 64 ) projecting from the tube ( 61 ), wherein the first housing ( 10 ) includes:
a tubular receptacle ( 12 ); two side walls ( 19 ) formed on circumferential ends of the receptacle ( 12 ); a lock arm ( 24 ) arranged between the side walls ( 19 ), the lock arm ( 24 ) holding the second housing ( 60 ) in a connected state; entrance spaces ( 29 ) formed between the side walls ( 19 ) and the lock arm ( 24 ), and the at least one wall ( 64 ) of the second housing ( 60 ) entering at least one of the entrance spaces ( 29 ); a fitting space ( 14 ) communicating with the entrance spaces ( 29 ), the tube ( 61 ) of the second housing ( 60 ) entering the fitting space ( 14 ) in the receptacle ( 12 ); and at least one protrusion ( 31 , 32 ) formed on at least one of facing surfaces of the side walls ( 19 ), the at least one protrusion ( 31 , 32 ) contacting the at least one wall ( 64 ) of the second housing ( 60 ) in a state connected to the second housing ( 60 ).

2 . The connector of claim 1 , wherein the at least one protrusion ( 31 , 32 ) has a flat end surface ( 33 ) configured to come into surface contact with the at least one wall ( 64 ) of the second housing ( 60 ).

3 . The connector of claim 2 , wherein the entrance space ( 29 ) is open to outside on a side opposite to the fitting space ( 14 ).

4 . The connector of claim 3 , wherein the at least one protrusion ( 31 , 32 ) includes a preceding protrusion ( 31 ) configured to contact the at least one wall ( 64 ) of the second housing ( 60 ) in an initial stage of connection of the first housing ( 10 ) and the second housing ( 60 ) and a succeeding protrusion ( 32 ) configured to contact the at least one wall ( 64 ) of the second housing ( 60 ) in a final stage of the connection of the first housing ( 10 ) and the second housing ( 60 ).

5 . The connector of claim 1 , wherein the entrance space ( 29 ) is open to outside on a side opposite to the fitting space ( 14 ).

6 . The connector of claim 1 , wherein the at least one protrusion ( 31 , 32 ) includes a preceding protrusion ( 31 ) configured to contact the at least one wall ( 64 ) of the second housing ( 60 ) in an initial stage of connection of the first housing ( 10 ) and the second housing ( 60 ) and a succeeding protrusion ( 32 ) configured to contact the at least one wall ( 64 ) of the second housing ( 60 ) in a final stage of the connection of the first housing ( 10 ) and the second housing ( 60 ).
