Connector and assembling method therefor

摘要

An object of the present invention is to enable a displacement of a wire in a bending direction to be effectively suppressed over the entire circumference. A one-piece rubber plug 20 includes a main body 21 including a plurality of insertion holes 24 and a plurality of tubular projections 22 communicating with the insertion holes 24 and projecting from the rear surface of the main body 21. Restricting surfaces 36 (restricting portions) matchable with restriction areas 25 on the outer peripheries of the tubular projections 22 are formed on through holes 33 of a rear holder 30. The rear holder 30 is displaced between a deformation permitting position which is reached by retracting the rear holder 30 such that the restricting surfaces 36 are not in contact with the restriction areas 25 and where resilient radially expansive deformations of the tubular projections 22 are permitted and a deformation preventing position where radially expansive deformations of the tubular projections 22 are prevented by bringing the restricting surfaces 36 into contact with the restriction areas 25 substantially over the entire circumferences.
