Abstract
Channels (20) are formed in a partition wall (19) between a sealing surface (14) on the outer peripheral surface of a housing (10) and ceiling surfaces (16a) of cavities (12a) having a back-to-back relationship with the sealing surface (14) by cutting the ceiling surfaces (16a) of the cavities (12a). Thus, even if the partition wall (19) is thick, a “sink mark” is difficult to form when the housing (10) is molded by a mold and, therefore, a deformation of the sealing surface (14) resulting the “sink mark” can be prevented.
Claims12
A watertight connector (F) having a housing (10) formed from a synthetic resin, a sealing surface (14) being defined on an outer peripheral surface of the housing (10) for receiving a seal (15), comprising:
- at least one cavity (12) formed in the housing (10) for receiving at least one corresponding terminal fitting (23);
- at least one lock (17) arranged along an inner wall surface (16) of the cavity (12) for preventing the corresponding terminal fitting (23) from coming out, the lock (17) having a back-to-back relationship with the sealing surface (14) and being spaced from the sealing surface (14),
- wherein at least one channel (20) is formed in a wall (19) between the sealing surface (14) and the inner wall surface (16) of the cavity (12) having a back-to-back relationship with the sealing surface (14) by cutting the inner wall surface (16) of the cavity (12).
A watertight connector (F) having a housing (10) formed from a synthetic resin, the housing (10) having opposite front and rear ends, at least one outer wall (19) extending between the front and rear ends, said outer wall (19) defining an outer peripheral surface of the housing (10), a portion of the outer peripheral surface between the front and rear ends defining a sealing surface (14), at least one cavity (12) extending through the housing (10) from the rear end to the front end thereof, the cavity (12) being formed partly by the outer wall (19), a resiliently deflectable lock (17) being formed in the cavity (12) and being cantilevered forwardly from a location on the outer wall (19) forwardly of the sealing surface (14), at least one channel (20) being formed in a surface of said outer wall (19) facing into the cavity (12) and extending from the lock (17) rearwardly to a location rearward of the sealing surface (14), such that said channel (20) is in substantially back-to-back relationship with said sealing surface (14).
