Abstract

A receptacle electrical connector has an insulated housing, a first terminal set, a second terminal set, a shielding plate and a metallic shell. The shielding plate has two connection portions formed respectively on two opposite sides of the shielding plate and each connection portion has a cutting surface. The cutting surface is formed on the connection portion, and the two cutting surfaces of the connection portions are exposed out of two opposite sides of the insulated housing. During the insert-molding processes of insulated housings, the connection beltings of metallic beltings are connected to the cutting surfaces of multiple shielding plates for simultaneously forming multiple insulated housings. Therefore, production efficiency and yield rate of the receptacle electrical connectors are enhanced.

First claim

What is claimed is:

1. A receptacle electrical connector comprising:
an insulated housing having
a base portion; and
a tongue portion formed on and protruding forward from the base portion;

a first terminal set mounted on the insulated housing and having multiple first terminals mounted on the insulated housing, and each first terminal having a first electrical contact section formed on a front end of the first terminal and mounted on a bottom surface of the tongue portion;
a second terminal set mounted on the insulated housing and having multiple second terminals mounted on the insulated housing, and each second terminal having a second electrical contact section formed on a front end of the second terminal and mounted on a top surface of the tongue portion, wherein the first terminal set and the second terminal set are substantially pointing symmetrical to each other with respect to a centre of symmetry of the tongue portion;
a shielding plate embedded in the tongue portion of the insulated housing, located between the first terminal set and the second terminal set, and having two connection portions protruding respectively from two opposite sides of the shielding plate, and each connection portion having a cutting surface formed on the connection portion, and the two cutting surfaces of the connection portions exposed out of two opposite side edges of the tongue portion, wherein the cutting surfaces are for connecting to a metallic belting; and
a metallic shell having a receiving cavity defined through the metallic shell and accommodating the insulated housing, the first terminal set and the second terminal set.

2. The receptacle electrical connector as claimed in claim 1 , wherein the insulated housing has
a first insulated housing; and
a second insulated housing mounted on the first insulated housing, wherein the base portion and the tongue portion are formed on the second insulated housing.

3. The receptacle electrical connector as claimed in claim 2 , wherein
the shielding plate further has two corner reinforcing elements formed respectively on the sides of the shielding plate adjacent to a front end of the shielding plate; and
the connection portions are formed respectively on the corner reinforcing elements; and
the cutting surfaces are formed respectively on the connection portions of the corner reinforcing elements and are exposed out of the side edges of the tongue portion adjacent to a front edge of the tongue portion.

4. The receptacle electrical connector as claimed in claim 2 , wherein the connection portions are formed respectively on and protrude outward from two opposite middle portions of the sides of the shielding plate.

5. The receptacle electrical connector as claimed in claim 4 , wherein the shielding plate further has two corner reinforcing elements formed respectively on the sides of the shielding plate adjacent to a front end of the shielding plate.

6. The receptacle electrical connector as claimed in claim 2 , wherein the first terminal set and the shielding plate are mounted on the first insulated housing by a first insert-molding process.

7. The receptacle electrical connector as claimed in claim 6 , wherein after the first insert-molding process, the first terminal set, the shielding plate and the first insulated housing are further mounted on the second insulated housing by a second insert-molding process.

8. The receptacle electrical connector as claimed in claim 7 further comprising an outer metallic shell mounted on the metallic shell and having two soldering legs formed on and protruding downward respectively from two opposite sides of the outer metallic shell.

9. A receptacle electrical connector comprising:
an insulated housing having a base portion and a tongue portion formed on and protruding forward from the base portion;
a first terminal set held in the insulated housing and having multiple first terminals held in the insulated housing, and each first terminal having a first electrical contact section formed on a front end of the first terminal and disposed on a bottom surface of the tongue portion;
a second terminal set held in the insulated housing and having multiple second terminals held in the insulated housing, and each second terminal having a second electrical contact section formed on a front end of the second terminal and mounted on a top surface of the tongue portion, wherein the first terminal set and the second terminal set are substantially pointing symmetrical to each other with respect to a centre of symmetry of the tongue portion;
a shielding plate embedded in the tongue portion of the insulated housing, located between the first terminal set and the second terminal set, and having two connection portions protruding respectively from two opposite sides of the shielding plate, and each connection portion having a cutting surface formed on the connection portion, and the two cutting surfaces of the connection portions exposed out of two opposite side edges of the tongue portion, wherein the cutting surfaces are formed by removing connection beltings of a metallic belting; and
a metallic shell having a receiving cavity defined through the metallic shell and accommodating the insulated housing, the first terminal set and the second terminal set.

10. The receptacle electrical connector as claimed in claim 9 , wherein the connection beltings are formed respectively on and protrude outward from two opposite middle portions of the sides of the shielding plate.

11. The receptacle electrical connector as claimed in claim 9 , wherein the shielding plate further has two corner reinforcing elements formed respectively on the sides of the shielding plate adjacent to a front end of the shielding plate.

12. The receptacle electrical connector as claimed in claim 9 , wherein
the shielding plate further has two corner reinforcing elements formed respectively on the sides of the shielding plate adjacent to a front end of the shielding plate; and
the connection beltings are formed respectively on the corner reinforcing elements; and
the cutting surfaces are formed respectively on the connection beltings of the corner reinforcing elements and are exposed out of the side edges of the tongue portion adjacent to a front edge of the tongue portion.

13. The receptacle electrical connector as claimed in claim 9 further comprising an outer metallic shell enclosing the metallic shell and having two soldering legs protruding downward respectively from two opposite sides of the outer metallic shell.
