1. An electrical connector comprising:
- a terminal module including an insulative housing with two rows of contacts and a metallic shielding plate integrally formed within the housing;
the insulative housing including a base and tongue portion forwardly extending from the base along a front-to-back direction;
the base defining opposite front and rear faces in said front-to-back direction;
a glue groove formed in the base, and located between and spaced from said front face and said rear face in the front-to-back direction;
each of said contacts including a retention section exposed in the glue groove; and
a tubular metallic shield enclosing the terminal module and defining a mating cavity in front of the front face;
whereinthe shield forms an injection opening generally aligned with the glue groove in a vertical direction perpendicular to said front-to-back direction so as to allow liquid type glue to enter and fill the glue groove via said injection opening to form a waterproof part.

Abstract
An electrical connector includes an insulative housing and a plurality of contacts retained in the housing to commonly form a terminal module, a metallic shield enclosing the terminal module and forming a mating cavity, and a glue groove formed in a base of the housing and located behind the mating cavity, in which a glue part is received. The shield forms an opening communicating with the glue groove, through which the liquid type glue is injected into the glue groove and solidified therein.

8. A method of making an electrical connector comprising steps of:
-
providing a terminal module with an insulative housing and a plurality of contacts retained in the housing; providing the insulative housing with a base and a tongue portion extending forwardly from the base in a front-to-back direction; providing said base with opposite front and rear faces, and a glue groove located between the opposite front and rear faces in the front-to-back direction; assembling a metallic tubular shield upon the terminal module with therein an opening in communication with the glue groove; and injecting liquid type glue into the glue groove via said injection opening to form a waterproof part in said glue groove. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An electrical connector comprising:
-
a terminal module including an insulative housing with a plurality of contacts therein; a metallic shield enclosing the terminal module to form a mating cavity forwardly communicating with an exterior in a front-to-back direction; and a glue groove formed in the insulative housing and in communication with an exterior in a transverse direction perpendicular to said front-to-back direction;
whereinsaid shield includes an injection opening in communication with said the glue groove in said transverse direction so as to allow a liquid type glue to enter the glue groove to form a waterproof part. - View Dependent Claims (16, 18, 19, 20)
