Waterproof electrical connector having a sealer between conatct module and outer shell

A method of making an electrical connector, comprising the steps of:

• insert molding a contact module to comprise an insulative housing and a plurality of terminals in two rows affixed to the insulative housing, the insulative housing comprising an annular receiving groove, a base portion located behind the annular receiving groove, and a tongue portion extending forwardly from the annular receiving groove, each terminal comprising a contacting portion exposed to the surface of the tongue portion, a soldering portion and a connecting portion connected between the contacting portion and the soldering portion, the connecting portion comprising an exposed portion suspended in the annular receiving groove;
• attaching an inner metal shell to the contact module and enclosing an outer shell to the inner metal shell;
• injecting glue into the annular receiving groove to form a sealer sealing among the contact module, the inner metal shell and the outer shell;
• and
• the exposed portion being embedded in the glue;
• a step of insert-molding a reinforcing plate with an insulative shell to form the outer shell.

An electrical connector comprising:

• contact module including an insulative housing associated with a plurality of terminals therein, each of said terminals including a front contacting portion, a rear soldering portion and a middle connecting portion linked therebetween along a front-to-back direction, the housing forming a receiving groove to expose the connecting portions of said terminals;
• a metallic inner shell enclosing the contact module;
• an outer shell attached upon the inner shell;
• and
• a glue filled within the receiving groove to form a sealer intimately contacting the connecting portions, the inner shell and the outer shell;
• wherein the sealer forms an opening through which a linking portion of the inner shell extends in said front-to-back direction;
• wherein the sealer forms an opening through which a portion of the housing extends in said front-to-back direction;
• wherein said receiving groove forms two regions spaced from each other in a transverse direction perpendicular to said front-to-back direction, and offset from each other in said front-to-back direction;
• wherein said outer shell includes an insulative shell associate with a metallic reinforced plate soldered to the metallic inner shell;
• wherein said metallic inner shell forms a penetrating groove through which the sealer extends in a vertical direction perpendicular to said front-to-back direction;
• wherein said housing includes a tongue portion and a base portion, and the annular receiving groove is located between the tongue portion and the base portion.
