Electrical connector with improved metallic shutter mechanism

1. An electrical connector, comprising:

a metal shell defining a receiving space with a mating port;

an insulative housing defining a mating portion extending forwardly and received in the receiving space, the mating portion defining two rows of passageways exposed on opposite surfaces thereof;

a plurality of terminals comprising contact portions retained in the corresponding passageways of the mating portion; and

a shutter located in the mating port of metal shell; wherein

the shutter is made of metal sheet and pivotally mounted to the shell, the shutter comprises a main portion and a pair of shafts extending outwardly form two sides of one end of the main portion;

wherein the metal shell comprises a top wall, a bottom wall opposite to the top wall and a pair of side walls connecting the top wall with the bottom wall, the side walls define a pair of shaft holes to engage with the shafts; wherein a torsion spring is wrapped around one pivot shaft of the shutter and comprises one end abutting against an inner side of the shutter and an opposite end abutting against an inner side of the top wall; wherein the shell further comprises a guide portion bending rearward from a front edge of the top wall thereof and received in the receiving space; wherein the guide portion abuts against the shutter to prevent the shutter from rotating outwardly; wherein the shutter has a notch formed in the free end thereof, the notch is aligned with the mating portion of the housing; wherein the top wall comprises a front section and a rear section which unitarily extends from the front section, and the rear section is lower than the front section.

2. An electrical connector, comprising:

a metal shell defining a receiving space with a mating port;

an insulative housing defining a mating portion extending forwardly and received in the receiving space;

a plurality of terminals comprising contact portions retained in the mating portion; and

a shutter covering the mating port of metal shell; wherein

the shutter is made of metal sheet and pivotally mounted to the shell, the shutter comprises a main portion and a pair of shafts extending outwardly form two sides of one end of the main portion; wherein the metal shell comprises a top wall, a bottom wall opposite to the top wall and a pair of side walls connecting the top wall with the bottom wall, the side walls define a pair of shaft holes to engage with the shafts; wherein a torsion spring is wrapped around one pivot shaft of the shutter and comprises one end abutting against an inner side of the shutter and an opposite end abutting against an inner side of the top wall.

3. An electrical connector comprising:

an insulative housing defining a base and a mating tongue extending forwardly therefrom;

a plurality of terminals disposed in the housing with contacting sections exposed upon at least one face of the mating tongue;

a metallic shell enclosing the housing and defining a mating port into which the mating tongue extends; and

a shutter pivotally mounted to the shell about an axis; wherein

the shutter defines a main portion rotated about said axis for inwardly entering the mating port and defining a contour essentially in compliance with an entrance opening of said mating port except a notch recessed from a far edge opposite to said axis for not interfering with mating tongue during rotation of the shutter; wherein the entrance opening defines a chamfered side and a straight side, and said axis is located on the straight side; wherein the main portion of the shutter defines a chamfered structure in compliance with the chamfered side of the entrance opening; wherein the shell forms a guide portion to prevent excessive outward movement of the shutter; wherein the notch is dimensioned essentially one half of the entrance opening in a vertical direction; wherein the shell defines a raised portion on a front region of a top wall to receive the shutter when said shutter is inwardly rotated to a horizontal position; wherein said raised portion defines a cutout configured similar to the notch; wherein said raised portion is linked to remaining portion of the top wall only on two sides beside said cutout; wherein a torsion spring is protectively located under the raised portion to abut against the shutter; wherein said shutter is metallic.
