Abstract

An electrical connector includes an insulative housing, a number of terminals, and a metal shell attached to the housing. The terminals have a number of grounding contacts, power contacts, and signal contacts. Each terminal has a contacting portion, an inclined portion bent forwardly from the contacting portion at a bending point, and a soldering portion. The bending points have a first bending point located at the grounding contacts, a second bending point located at the power contacts, and a third bending point located at the signal contact. A distance between the first bending points of the grounding contacts and the insertion port is larger than that between the second bending points of the power contacts and the insertion port and smaller than that between the third bending points of the signal contacts and the insertion port.

First claim

What is claimed is:

1. An electrical connector, defining an insertion port, a mating direction, a transverse direction perpendicular to the mating direction, and a vertical direction perpendicular to the mating direction and the transverse direction, comprising:
an insulative housing;
a plurality of terminals retained in the insulative housing, the terminals having a plurality of grounding contacts, power contacts, and signal contacts, each terminal having a contacting portion exposed from the insulative housing, an inclined portion bent forwardly from the contacting portion at a bending point and retained in the insulative housing, and a soldering portion extending backwardly, the bending points of the terminals having first bending points located at the grounding contacts, second bending points located at the power contacts, and third bending points located at the signal contacts, a distance between the first bending points of the grounding contacts and the insertion port being larger than that between the second bending points of the power contacts and the insertion port and smaller than that between the third bending points of the signal contacts and the insertion port; and
a metal shell attached to the insulative housing; a metallic shielding plate retained in the insulative housing, and wherein the metal shell has a main portion, a connecting portion bent downwardly from a rear end of the main portion, a shielding wall bent backwardly from a bottom end of the connecting portion, and a pair of affixed arms extending forwardly from two sides of the shielding wall, the main portion defines an upper surface, a lower surface, a pair of side surfaces connected with the upper surface and the lower surface, and a pair of lateral wall extending backwardly from the side surfaces and located beside the shielding wall, and the affixed arms are resisted against by the lateral walls; wherein the lateral wall of the metal shell includes a pair of first soldering sections extending downwardly therefrom, the metallic shielding plate has a pair of soldering legs, the soldering legs are close to the first soldering sections and beyond adjoining the first soldering sections, and the affixed arms are located above the first soldering sections along the vertical direction; wherein the side surfaces have a pair of second soldering sections, each second soldering section includes a panel portion extending from the side surface and a vertical portion extending downwardly from the panel portion, and the panel portion has a dimple close to the insertion port and protruding downwardly; a shielding shell located in the metal shell, a front end of the shielding shell being exposed from the metal shell.

2. The electrical connector as claimed in claim 1 , wherein the first bending point is located behind the second bending point away from the insertion port, and the first bending points and the second bending points define a distance at 0.2 mm.

3. The electrical connector as claimed in claim 1 , wherein the shielding wall has a rear wall extending downwardly from a rear end thereof and the affixed arms are bent forwardly from two sides of the rear wall and extend outside the lateral walls.

4. The electrical connector as claimed in claim 3 , wherein said insulative housing has a pair of receiving slots, the shielding wall has a pair of affixed portion extending forwardly from a bottom end of the rear wall and received in the receiving slots.

5. The electrical connector as claimed in claim 1 , wherein the affixed arms are bent downwardly from two sides of the shielding wall and extend outside the lateral wall.

6. The electrical connector as claimed in claim 5 , wherein the insulative housing has a pair of grooves, and the lateral walls have a pair of resisting portions extending inwardly from a pair of rear end thereof and received in the grooves of the insulative housing.

7. An electrical connector comprising:
a pair of terminal modules sandwiching a metallic shielding plate therebetween in a vertical direction, each of said terminal modules including a plurality of contacts embedded within an insulator via an insert-molding process and arranged with one another along a transverse direction perpendicular to said vertical direction, each of said contacts including a front contacting section and a rear soldering section along a front-to-section direction perpendicular to both said vertical direction and said transverse direction, and an inclined section located at a front end of the contacting section and angled at a bending point therebetween;
said contacts including signal contacts, power contacts and grounding contacts; wherein
the inclined sections of the power contacts and the grounding contacts extend forwardly beyond those of the signal contacts in said front-to-back direction, and the bending points of the grounding contacts are located between those of the power contacts and those of the signal contacts along the front-to-back direction in a side view; wherein the inclined sections of the grounding contacts in one of said terminal modules are mechanically and electrically connected to those of the corresponding grounding contacts of the other of said terminal modules in said vertical direction; wherein said shielding plate includes an opening in which the inclined sections of the grounding contacts of said one of the terminal modules are connected with those of the corresponding grounding contacts of the other of the terminal modules in the vertical direction.

8. The electrical connector as claimed in 7 , further including a metallic shielding shell enclosing said pair of terminal modules and said shielding plate, wherein a metallic main shell is attached upon the shielding shell and defines a Z-shaped rear wall to cover a rear side of the whole connector.

9. An electrical connector comprising:
a pair of terminal modules sandwiching a metallic shielding plate therebetween in a vertical direction, each of said terminal modules including a plurality of contacts embedded within an insulator via an insert-molding process and arranged with one another along a transverse direction perpendicular to said vertical direction, each of said contacts including a front contacting section and a rear soldering section along a front-to-section direction perpendicular to both said vertical direction and said transverse direction, and an inclined section located at a front end of the contacting section and angled at a bending point therebetween;
said contacts including signal contacts, power contacts and grounding contacts; wherein
the shielding plates forms an opening in which the inclined section of the grounding contact in one of said pair of terminal modules is mechanically and electrically connected to that of the corresponding grounding contact in the other of said pair of terminal modules in said vertical direction; wherein another insulator is applied upon said pair of terminal modules to fill said opening so as to secure said inclined sections of said grounding contacts in said opening; wherein the bending point of the grounding contact is closely aligned with an end of the opening of the shielding plate in the vertical direction.
