Abstract

An electrical connector has an insulating body which comprises a housing and a tongue; a plurality of conductive terminals, each conductive terminal has a mating portion and a soldering portion; a metal inner shell which surrounds to form a first frame, the first frame is fixed on the insulating body and surrounds a rear portion of the tongue to form a mating cavity; a metal outer shell which surrounds to form a second frame, the second frame encircles an outside of the first frame, a plurality of soldering legs extend out from two sides of the metal outer shell; and an insulating outer shell which is engaged with the metal outer shell integrally, a rear portion of the insulating outer shell is formed with a receiving cavity; the metal inner shell is correspondingly inserted in the receiving cavity, the insulating outer shell surrounds a front portion of the tongue and forms an insertion opening, the insertion opening is integrally communicated with the mating cavity along a front-rear direction. The present disclosure can increase the overall structure strength and facilitate the smooth insertion of another mating connector.

First claim

What is claimed is:

1. An electrical connector, which is used to correspondingly mate with another mating connector, comprising:
an insulating body which comprises a housing and a tongue extending forwardly out from the housing;
a plurality of conductive terminals, each conductive terminal having a mating portion exposed on the tongue and a soldering portion extending backwardly out from the housing;
wherein the electrical connector further comprising:
a metal inner shell which surrounds to form a first frame, the first frame being fixed on the insulating body and surrounding a rear portion of the tongue to form a mating cavity;
a metal outer shell which surrounds to form a second frame, the second frame encircling an outside of the first frame, the metal outer shell being electrically connected with the metal inner shell together, a plurality of soldering legs extending out from two sides of the metal outer shell; and
an insulating outer shell which is engaged with the metal outer shell integrally, a rear portion of the insulating outer shell being formed with a receiving cavity;
wherein the metal inner shell being correspondingly inserted in the receiving cavity, the insulating outer shell surrounding a front portion of the tongue and forming an insertion opening, the insertion opening being integrally communicated with the mating cavity along a front-rear direction.

2. The electrical connector according to claim 1 , wherein
the metal inner shell further comprises two first wing plates extending out from a rear end of the first frame;
the metal outer shell further comprises two second wing plates respectively extending out from the second frame, the two second wing plates correspondingly stack above the two first wing plates and are correspondingly electrically connected.

3. The electrical connector according to claim 2 , wherein the housing of the insulating body protrudes backwardly to provide a support portion, the two first wing plates are correspondingly supported on the support portion.

4. The electrical connector according to claim 3 , wherein
the soldering portions of the conductive terminals extend backwardly out from the support portion;
the electrical connector further comprises a seal formed by a sealing glue applied on a rear portion of the receiving cavity of the insulating outer shell, the support portion passes backwardly through the seal.

5. The electrical connector according to claim 2 , wherein two sides of the second frame are respectively torn and bent to respectively form two soldering legs, two outer sides of the two second wing plates are also respectively bent to form two soldering legs.

6. The electrical connector according to claim 2 , wherein the first wing plate and the second wing plate are securely connected together by laser spot welding.

7. The electrical connector according to claim 1 , wherein a plurality of abutting convex portion protrude from the first frame toward the inside of the mating cavity, and are used to engage with the another mating connector.

8. The electrical connector according to claim 1 , wherein an internal contour of the insertion opening is equal to or slightly smaller than an internal contour of the mating cavity, and the another mating connector passes through the insertion opening and inserts into the mating cavity.

9. The electrical connector according to claim 1 , wherein the insulating outer shell is engaged with the metal outer shell integrally by insert molding process; and wherein the second frame is penetratingly provided with a plurality of fixing holes, the insulating outer shell are correspondingly formed with a plurality of fixing columns which protrude into the fixing holes respectively.

10. The electrical connector according to claim 1 , wherein an outer periphery of a front portion of the insulating outer shell is sheathed with a waterproof sealing ring.
