A connector includes: a first connector housing which allows a second connector housing to be fitted in a fitting direction; and a retainer which is inserted, in an insertion direction perpendicular to the fitting direction, into the first connector housing, and which includes: a housing lock arm engaged with a lock protrusion provided in the first connector housing to position the retainer in a temporary lock position and a regular lock position when the retainer is inserted into the first connector housing; and a terminal lock portion engaged with a terminal metal fitting provided in the first connector housing to prevent the terminal metal fitting from dropping off when the retainer is positioned in the regular lock position. The retainer includes an arm support portion which supports both ends of the housing lock arm extending in the insertion direction.
1. A connector comprising:
a first connector housing which comprises: a terminal receiving portion; and a hood portion which is formed to have a cylindrical structure which surrounds the terminal receiving portion to define a gap around the terminal receiving portion such that a cylindrical portion of a second connector housing is allowed to be fitted into the gap in a fitting direction; and
a retainer which is inserted, in an insertion direction perpendicular to the fitting direction, into the first connector housing from a retainer inserting port opened in one side surface of the first connector housing, and which comprises: a housing lock arm which is engaged with a lock protrusion provided in the first connector housing to position the retainer in a temporary lock position and a regular lock position when the retainer is inserted into the first connector housing; and a terminal lock portion which is engaged with a terminal metal fitting provided in the terminal receiving portion to prevent the terminal metal fitting from dropping off when the retainer is positioned in the regular lock position,
wherein the retainer comprises an arm support portion which supports both ends of the housing lock arm extending in the insertion direction.
2. The connector according to claim 1 ,
wherein the housing lock arm comprises a housing lock portion which is engaged with the lock protrusion provided in the first connector housing such that the housing lock portion engaged with the lock protrusion is flexibly deformed in the fitting direction.
3. The connector according to claim 1 , further comprising:
a cylindrical packing which is outer-fitted to the terminal receiving portion of the first connector housing,
wherein the retainer comprises a packing holding portion which opposes an end portion of the packing from a front end side of the terminal receiving portion to restrict the packing from moving in a detachment direction.
