Abstract

A receptacle connector includes an insulative housing equipped with a plurality of receptacle contacts and enclosed by a capsular metallic shield sub-assembly. An insulative holder encloses the shield sub-assembly with a deflectable latching structure thereon. The plug connector includes an insulative body equipped with a plurality of plug contacts. An internal PCB is located behind the housing and soldered with the corresponding contacts. A capsular metallic shell encloses the insulative body and adapted to be received within the metallic shield during mating. A cable is connected to the PCB. An insulative cover encloses the internal PCB, the rear portion of the insulative body and the front portion of the cable with a retaining structure to be coupled with the latching structure, and a sliding assurance structure ensuring the latching structure and the retaining structure to be securely engaged with each other for maintaining the reliable mating.

First claim

What is claimed is:

1 . A USB (Universal Serial Bus) Type C electrical connector assembly comprising:
a Type C receptacle adapted to be mated with a Type C plug connector along a mating direction, said receptacle connector including an insulative housing with a plurality of receptacle contacts, and a metallic shield enclosing the housing to form mating cavity; said plug connector including an insulative body with a plurality of plug contacts, and a metallic shell enclosing the body with a mating port to be received in the mating cavity, and a cover forming an exterior of the plug connector; an insulative holder intimately surrounding the metallic shield to protectively circumferentially shield a mating portion of the metallic shield; and an interlocking device including a deflectable latching structure engageable with a retaining structure and restrained by an assurance structure; wherein said assurance structure is moveably located upon the cover of the plug connector while one of the latching structure and the retaining structure is formed on the cover of the plug connector and the other of the latching structure and the retaining structure is formed on the holder of the receptacle connector.

2 . The USB Type C electrical connector assembly as claimed in claim 1 , wherein the deflectable latching structure is formed on holder of the receptacle connector.

3 . The USB Type C electrical connector assembly as claimed in claim 1 , wherein the assurance structure is moved along the mating direction.

4 . The USB Type C electrical connector assembly as claimed in claim 1 , wherein said assurance structure is constantly urged by a spring to a locking position where the deflectable latching structure is restrained.

5 . The USB Type C electrical connector assembly as claimed in claim 4 , wherein said assurance structure is moveable to an unlocking portion away from the receptacle connector than the locking position.

6 . The USB Type C electrical connector assembly as claimed in claim 1 , wherein said insulative holder is overmolded upon the metallic shield.

7 . The USB Type C electrical connector assembly as claimed in claim 1 , wherein said plug connector is linked by a cable.

8 . A USB (Universal Serial Bus) Type C electrical connector assembly comprising:
a Type C receptacle adapted to be mated with a Type C plug connector along a mating direction, said receptacle connector including an insulative housing with a plurality of receptacle contacts, and a metallic shield enclosing the housing to form mating cavity; said plug connector including an insulative body with a plurality of plug contacts, and a metallic shell enclosing the body with a mating port to be received in the mating cavity, a cover forming an exterior of the plug connector; an insulative holder intimately surrounding the metallic shield to protectively circumferentially shield a mating portion of the metallic shield; and an interlocking device including at least a moveable latching structure engageable with a retaining structure; wherein one of the latching structure and the retaining structure is formed on the cover of the plug connector and the other of the latching structure and the retaining structure is formed on the holder of the receptacle connector.

9 . The USB Type C electrical connector assembly as claimed in claim 8 , wherein the latching structure is deflectable.

10 . The USB Type C electrical connector assembly as claimed in claim 9 , wherein said latching structure is unitarily formed on the insulative holder.

11 . A USB (Universal Serial Bus) Type C electrical connector assembly comprising:
a Type C receptacle adapted to be mated with a Type C plug connector along a mating direction, said receptacle connector including an insulative housing with a plurality of receptacle contacts, and a metallic shield enclosing the housing to form mating cavity; said plug connector including an insulative body with a plurality of plug contacts, and a metallic shell enclosing the body with a mating port to be received in the mating cavity, and a cover forming an exterior of the plug connector; an insulative holder intimately surrounding the metallic shield to protectively circumferentially shield a mating portion of the metallic shield; and an interlocking device including a deflectable latching structure engageable with a retaining structure and restrained by an assurance structure; wherein said assurance structure is located upon one of the plug connector and the receptacle connector, one of the latching structure and the retaining structure is formed on the cover of the plug connector and the other of the latching structure and the retaining structure is formed on the holder of the receptacle connector, and the assurance structure abuts against the latching structure transversely.

12 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein the deflectable latching structure is formed on holder of the receptacle connector.

13 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein the assurance structure is moved along the mating direction.

14 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein said assurance structure is constantly urged by a spring to a locking position where the deflectable latching structure is restrained.

15 . The USB Type C electrical connector assembly as claimed in claim 14 , wherein said assurance structure is moveable to an unlocking portion away from the receptacle connector than the locking position.

16 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein said insulative holder is overmolded upon the metallic shield.

17 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein said plug connector is linked by a cable.

18 . The USB Type C electrical connector assembly as claimed in claim 11 , wherein said receptacle connector is mounted upon a printed circuit board.

19 . The USB Type C electrical connector assembly as claimed in claim 19 , wherein said assurance structure is located upon the cover of the plug connector.
