Electrical connector having an improved O-ring and method of making the same
First Claim
1. An electrical connector assembly comprising:
- an electrical connector including;
an insulative housing having a base portion and a tongue portion extending forwardly from the base portion;
a plurality of conductive terminals affixed to the insulative housing; and
a shielding shell enclosing the insulative housing and affixing with the base portion; and
an outer frame receiving the electrical connector;
whereinan annular groove is formed between an outer surface of the shielding shell and an inner wall of the outer frame, the outer frame has a plurality of dispensing holes penetrating the inner wall and an outer wall thereof and communicating with the annular groove, and an o-ring is formed by injecting insulative materials into the annular groove through the dispensing holes to seal a gap between the shielding shell and the outer frame;
the shielding shell comprises a pair of barriers at a junction of the first cylindrical portion and the second cylindrical portion, the barriers resist a front surface of the base portion, and the sub shell is spot-welded on the rear surface of the barriers; and
the electrical connector comprises a sub shell secured to the barriers.

Abstract
An electrical connector assembly includes an electrical connector and an outer frame receiving the electrical connector. The electrical connector includes an insulative housing, a number of conductive terminals affixed to the insulative housing, and a shielding shell enclosing the insulative housing. The insulative housing includes a base portion and a tongue portion. There exists an annular groove between an outer surface of the shielding shell and an inner wall of the outer frame. The outer frame includes a number of dispensing holes penetrating the inner wall and an outer wall thereof and communicating with the annular groove. An o-ring is injected into the annular groove through the dispensing holes by the insulative materials sealing a gap between the shielding shell and the outer frame. Since the o-ring is formed after assembling the electrical connector to the outer frame, the gap is better sealed.

10. A method of making an electrical connector assembly, comprising steps of:
-
providing a contact module including an insulative housing and a plurality of conductive terminals affixed to the insulative housing, said housing including a base portion and a tongue portion extending forwardly from the base portion in a front-to-back direction; providing a shielding shell including a front cylindrical portion and a rear hollow portion in the front-to-back direction, said front cylindrical portion having a first annular portion extending forwardly along said front-to-back direction; forwardly inserting the contact module into the shielding shell along said front-to-back direction to extend the tongue portion forwardly beyond the portion shielding shell; providing an outer frame to surround both the front cylindrical portion and the tongue portion, said outer frame forming an annular groove at an interior surface thereof to surround and be closed by the first annular portion of the front cylindrical portion and at least one dispensing hole communicating with the annular groove; and pouring a glue liquid from the dispensing hole into the annular groove to form an o-ring which intimately adheres to both the outer frame and the first annular portion. - View Dependent Claims (11, 12, 13)

14. An electrical connector assembly comprising:
-
a contact module including an insulative housing and a plurality of contacts retained to the housing, said housing including a base portion and a tongue portion extending forwardly from the base portion in a front-to-back direction; a metallic shell enclosing the contact module and having a front cylindrical portion beyond which the tongue portion forwardly extends in the front-to-back direction; an outer frame enclosing both the front cylindrical portion and the tongue portion and having an annular groove surrounding and closed by said front cylindrical portion; and a glue ring fills said annular groove in an adhesive manner;
whereinthe outer frame forms at least one dispensing hole communicating the annular groove with an exterior for injection of the glue ring. - View Dependent Claims (15, 16, 17, 18)
