An apparatus in which a pair of hollow molding portions 53 and 54 for molding in which a terminal connecting portion with a terminal fitting 20 crimped onto a conductor 11 at a tip portion of a sheathed wire 10 is accommodated and set are provided inside a mold 50 made up by an upper mold 51 and a l

An apparatus in which a pair of hollow molding portions 53 and 54 for molding in which a terminal connecting portion with a terminal fitting 20 crimped onto a conductor 11 at a tip portion of a sheathed wire 10 is accommodated and set are provided inside a mold 50 made up by an upper mold 51 and a lower mold 52 , a molding resin 30 in a molten state being injected and poured into the molding portions 53 and 54 to cover and mold the terminal connecting portion so as to provide waterproofing, the terminal connecting portion subjected to covering and molding being released from the mold so as to be removed outside the mold. A casting surface of the molding portion 53 of the upper mold 51 is provided with a gradient or a curvature for facilitating the release of the terminal connecting portion subjected to covering and molding from the mold, whereby the terminal connecting portion subjected to covering and molding remains in the molding portion 54 of the lower mold 52 during mold releasing.

1. A system for providing a waterproof terminal connecting portion of a sheathed wire, comprising:a terminal fitting connected to a bared conductor of the sheathed wire at a first part of the sheathed wire, wherein the terminal fitting includes an upper face having a curvature;an upper mold having an inner space provided with a dome-shaped ceiling face, which defines an upper part of a molding cavity in which the first part of the sheathed wire is accommodated and molten resin covering a part of the terminal fitting is injected therein; anda lower mold having an inner space which defines a lower part of the molding cavity,wherein a curvature of the dome-shaped ceiling face is made coincident with the curvature of the upper face of the terminal fitting so that a thickness of the molten resin between the ceiling face and the upper face of the terminal fitting is substantially identical. 2. The system as set forth in claim 1, wherein the dome-shaped ceiling face comprises at least two radii of curvature in an identical cross-sectional plane, in accordance with a shape of an outer face of the terminal fitting.
