Abstract

An electrical connector ( 100 ) includes an insulative body ( 2 ), a number of contacts ( 1 ), and a metal shell ( 5 ). The insulative body includes an upper wall ( 21 ), a lower wall ( 22 ) opposite to the upper wall, a pair of sidewalls ( 23 ), and a rear wall ( 24 ) connecting between the upper wall, the lower wall, and the sidewalls for cooperatively defining a receiving space ( 20 ). The insulative body has a mating tongue ( 25 ) extending forwardly from the rear wall into the receiving space. The contacts are retained in the mating tongue and partly exposed in the receiving space. The metal shell has a pair of arc portions engaging with a mating plug connector. The metal shell is positioned on the upper wall for reducing interference between the metal shell and an antenna mounted on a printed circuit board.

First claim

What is claimed is:

1. An electrical connector for mounting on a printed circuit board, comprising:
an insulative body comprising an upper wall, a lower wall opposite to the upper wall, a pair of sidewalls, and a rear wall connecting between the upper wall, the lower wall, and the sidewalls for cooperatively defining an receiving space, the insulative body having a mating tongue extending forwardly from the rear wall into the receiving space;
a plurality of contacts retained in the mating tongue and partly exposed in the receiving space for engaging with a mating plug connector;
a metal shell having a pair of arc portions for engaging with the mating plug connector;
wherein the metal shell is positioned on the upper wall for reducing interference between the metal shell and an antenna mounted on the printed circuit board, wherein the metal shell has a length along a front-and-rear direction smaller than that of the receiving space, wherein the metal shell comprises a pair of locking portions and a connection portion connecting between the locking portions, and the arc portions are respectively positioned on the locking portions and separated away from each other by the connection portion.

2. An electrical connector assembly comprising:
an insulative housing including a base portion with a mating tongue extending forwardly therefrom in a front-to-back direction;
said insulative housing defining a mating cavity in which said mating tongue extends horizontally;
a plurality of contacts disposed in the housing with contacting sections exposed upon one surface of the mating tongue;
a metallic plate disposed in the housing and exposed upon the other surface of the mating tongue; and
a metallic bracket embedded within the housing with a pair of locking portions communicating with the mating cavity, and a pair of board locks exposed outside of the housing for mounting to a printed circuit board without grounding but retaining thereto; wherein
the contacts, the metallic plate and the metallic bracket are all integrally formed with the housing via an insert molding process, wherein said bracket forms two opposite end sections exposed upon two opposite side walls of the housing for linking to a corresponding carrier during the insert molding process, wherein said metallic plate includes two opposite end sections exposed to the opposite side walls and located behind the opposite end sections of the metallic bracket, further including another pair of metallic board locks secured to the housing via said insert molding process, wherein each of said board locks includes a vertical sections for locking to the printed circuit board and an end section exposed to the corresponding side wall for linking to a corresponding carrier, the end section of said another board lock being located behind the end section of the metallic bracket and the end section of the metallic plate, wherein said another pair of board locks are configured to be grounded to the printed circuit board.

3. The electrical connector assembly as claimed in claim 2 , wherein said bracket essentially does not surround said mating cavity but with at least one interior face of the housing exposed to the mating cavity without being shielded by the metallic bracket.

4. The electrical connector assembly as claimed in claim 3 , wherein said bracket includes a cutout between said pair of locking portions.

5. The electrical connector assembly as claimed in claim 2 , wherein the housing is received within a notch of the printed circuit board while the metallic bracket is essentially located above the printed circuit board.

6. The electrical connector assembly as claimed in claim 2 , wherein the metallic bracket is dimensioned around one half of the housing along a front-to-back direction.

7. An electrical connector assembly comprising:
a printed circuit board defining a notch with a protruding mounting region extending from an inner edge into the notch;
an electrical connector including:
an insulative housing including a base portion with a mating tongue extending forwardly therefrom in a front-to-back direction;
said insulative housing defining a mating cavity in which said mating tongue extends horizontally;
a plurality of contacts disposed in the housing with contacting sections exposed upon one surface of the mating tongue;
a metallic plate disposed in the housing and exposed upon the other surface of the mating tongue;
a metallic shell embedded within the housing with a pair of locking portions communicating with the mating cavity, and a pair of board locks exposed outside of the housing for mounting to said printed circuit board; and
the housing forms a recessed portion in a rear side and tails of the contacts are disposed in said recessed portion; wherein
the housing is located in the notch and the protruding mounting region is received within the recessed portion and soldered to tails of the connector, wherein the metallic shell is integrally formed with the housing via an insert molding process, and the metallic shell forms two opposite end sections exposed on two opposite side walls of the housing for linking to a corresponding carrier during said insert molding process, wherein the metallic plate is integrally formed with the housing via said insert molding process, said metallic plate forms opposite end sections exposed on the two opposite side walls of the housing for linking to a corresponding carrier during the insert molding process, and the end sections of the metallic plate being located behind those of the metallic shell, further including another pair of board locks integrally formed with the housing via said insert molding process, wherein said board locks include a pair of end section exposed upon two opposite side walls, respectively, said end sections of said another pair of board lock being located behind both those of the metallic plate and those of the metallic shell.

8. The electrical connector assembly as claimed in claim 7 , wherein both the pair of board locks and said another pair of board locks include horizontal sections seated upon the printed circuit board and vertical sections extending into corresponding holes in the printed circuit board.

9. The electrical connector assembly as claimed in claim 7 , wherein the metallic shell does not fully surround the mating cavity but leaving one side face of the mating cavity exposed to an interior face of the housing.

10. The electrical connector assembly as claimed in claim 7 , wherein the metal shell forms a cutout between the pair of locking portion.

11. The electrical connector assembly as claimed in claim 7 , wherein the metallic bracket is dimensioned around one half of the housing along a front-to-back direction.
