Abstract

An electrical connector, comprises: an insulative housing; a plurality of contacts received into the insulative housing and having a plurality of soldering portion extending rearwardly and beyond a rear surface of the insulative housing; a metallic shell enclosing the insulative housing; and a cover formed on a rear end of the insulative housing and the metallic shell and sealed the rear surface of the insulative housing.

First claim

What is claimed is:

1. An electrical connector, comprising:
an insulative housing;
a plurality of contacts received into the insulative housing and having a plurality of soldering portion extending rearwardly and beyond a rear surface of the insulative housing;
a metallic shell enclosing the insulative housing; and
a cover formed on a rear end of the insulative housing and the metallic shell and sealing the rear surface of the insulative housing, wherein the insulative housing comprises an emboss portion, and an annular slot is formed between an outer periphery surface of the emboss portion and an inner surface of the metallic shell, and the annular slot is fully filled with an annular portion of the cover, wherein the insulative housing defines a plurality of passageways, the plurality of contacts are respectively received into the corresponding passageways, a plurality of gaps respectively formed between the plurality of contacts and the corresponding passageways, and the plurality of gaps are respectively fully fill with a plurality of protruding portions of the cover, wherein the cover is formed by an over-molding process, the insulative housing further comprises a base portion and a tongue portion extending forwardly from the base portion, the emboss portion extends rearwardly from the base portion, wherein metallic shell defines an upper wall, a lower wall and two lateral walls respectively connected with the upper wall and the lower wall, wherein the base portion defines two recesses formed at two lateral surfaces thereof, the two lateral walls of the metallic shell defines two elastic tabs cooperated with the two recesses to achieve an engagement between the insulative housing and the metallic shell, wherein the base portion further defines two protrusions respectively formed on top and bottom surfaces, the metallic shell defines two indentations respectively formed on the upper and lower wall and cooperated with the two protrusions, wherein the emboss portions defines two flanges respectively formed on top and bottom surfaces and located in back of the two protrusions, the cover defines two arm portions respectively engaged with the protrusions and the flanges, wherein base portion defines a plurality of cutouts formed on a rear periphery edge thereof, the cover defines a plurality of projections cooperated with the plurality of corresponding cutouts.

2. A method of making a waterproof electrical connector, comprising steps of:
providing an insulative housing with a front mating port and a rear connecting port with a plurality of passageways extending therethrough in a front-to-back direction;
forwardly inserting a plurality of contacts into the rear openings of corresponding passageways, respectively, from the connecting port, wherein each of said contacts defining a Z like tail portion with an upper horizontal section extending rearwardly from the rear opening of the corresponding passageway, a lower horizontal section for surface mounting to a printed circuit board, and a standing section linked between said upper and lower horizontal sections, said standing section is spaced from a rear face of the housing with a gap;
providing a hollow metallic shell and forwardly assembling the housing into the shell; and
applying an insulative cover plate upon the connecting port in an upstanding manner via an overmolding process to cover said rear openings of the passageways, wherein said cover plate fills the gaps to provide support against the standing sections, wherein the cover plate includes a circumferential flange forwardly extending from an inner face thereof.
