Abstract

An electrical plug connector includes a metallic shell, and two conductive contact members. The two conductive contact members are respectively received in a top concave region and a bottom concave region of the insulated housing. When the electrical plug connector is inserted into a metallic shell of the electrical receptacle connector, each conductive contact members of the electrical plug connector comes in contact with the inner surface of the metallic shell of the electrical receptacle connector and a low-impedance grounding path is established between the metallic shell of the electrical plug connector and the metallic shell of the mating electrical receptacle connector through each conductive contact member.

First claim

What is claimed is:

1. An electrical plug connector, comprising:
a metallic shell defining a receiving cavity and comprising a plurality of holes located thereon;
an insulated housing received in the receiving cavity, wherein the insulated housing comprises an upper member defining a top concave region, a lower member defining a bottom concave region, and defines a mating room being located between the upper member and the lower member;
a plurality of upper-row elastic terminals held in the upper member, wherein each upper-row elastic terminal partly projects into the mating room;
a plurality of lower-row elastic terminals held in the lower member, wherein each lower-row elastic terminal partly projects into the mating room; and
two conductive contact members respectively received in the top concave region and the bottom concave region, wherein each of the conductive contact members comprises:
a elongated sheet portion;
a resilient portion extending forward from the elongated sheet portion; and
a plurality of dome-shaped contact portions perpendicularly formed from the resilient portion, wherein the dome-shaped contact portions are located at a natural position and each dome-shaped contact portion is protruded outward the circumferential edge of each hole of the metallic shell before the electrical plug connector is inserted into an electrical receptacle connector, and the dome-shaped contact portions are located at a mating position and the dome-shaped contact portions are biased an inner surface of a metallic shell of the electrical receptacle connector, thereby causing each resilient portion being deflected and each dome-shaped contact portion being underneath the circumferential edge of each hole of the metallic shell after the electrical plug connector is inserted into the electrical receptacle connector.

2. The electrical plug connector according to claim 1 , wherein each dome-shaped contact portion is aligned with each hole of the metallic shell and protruded outward over the circumferential edge of each hole of the metallic shell when each conductive contact member and the metallic shell of the electrical plug connector are properly overlapped and joined.

3. The electrical plug connector according to claim 1 , wherein each conductive contact member further comprises a conductive contact plate formed in a region of the conductive contact member, which contacts an inner surface of the metallic shell of the electrical plug connector.

4. The electrical plug connector according to claim 3 , wherein each conductive contact plate is cantilevered and inclined sideways by cutting and raising a portion of each conductive contact member.

5. The electrical plug connector according to claim 4 , wherein when the electrical plug connector is inserted into the metallic shell of the electrical receptacle connector, the dome-shaped contact portions come in contact with the inner surface of the metallic shell of the electrical receptacle connector.

6. The electrical plug connector according to claim 1 , wherein each resilient portion further comprise a plurality of strip-shaped portions extended from the corresponding elongated sheet portion in the rear-to-front direction and the adjacent strip-shaped portions are separated by a distance along a transverse direction perpendicular to the rear-to-front direction.

7. The electrical plug connector according to claim 1 , wherein each upper-row elastic terminal comprises a body portion, a tail portion extending backward form the body portion, and a flexible contact portion extending from the body portion and partly projecting into the mating room, and wherein each lower-row elastic terminal comprises a body portion, a tail portion extending backward form the body portion, and a flexible contact portion extending from the body portion and partly projecting into the mating room.

8. The electrical plug connector according to claim 7 , wherein the body portions of the upper-row elastic terminals are held in the upper member and the body portions of the lower-row elastic terminals are held in the lower member.

9. The electrical plug connector according to claim 8 , wherein the upper-row elastic terminals are assembled or inserted molding in the upper member.

10. The electrical plug connector according to claim 8 , wherein the lower-row elastic terminals are assembled or inserted molding in the lower member.

11. The electrical plug connector according to claim 1 , wherein the upper-row elastic terminals comprise:
two pairs of upper differential pairs for signal transmission;
two ground terminals located at two opposite sides of the upper-row elastic terminals; and
two power terminals, wherein each of the upper differential pairs is located between one of the power terminals and one of the ground terminals.

12. The electrical plug connector according to claim 1 , wherein the lower-row elastic terminals comprise:
two pairs of lower differential pairs for signal transmission;
two ground terminals located at two opposite sides of the lower-row elastic terminals; and
two power terminals, wherein each of the lower differential pairs is located between one of the power terminals and one of the ground terminals.

13. The electrical plug connector according to claim 1 , wherein the insulated housing further defines a plug opening which is located at the front of the upper member and the lower member and communicates with the mating room.

14. The electrical plug connector according to claim 13 , wherein the upper member and the lower member further defines two recessed portions which are respectively concaved in the top concave region and the bottom concave region and are adjacent to the plug opening.

15. The electrical plug connector according to claim 14 , wherein the two recessed portions respectively penetrate through the inner surfaces of the top and the bottom concave regions.

16. The electrical plug connector according to claim 14 , wherein the dome-shaped contact portions and the resilient portions are deflected toward the corresponding recessed portions, thereby allowing the movement of the dome-shaped contact portions and the resilient portions in a space within the interiors of the corresponding recessed portions.

17. The electrical plug connector according to claim 1 , wherein the upper member and the lower member respectively define two catching grooves respectively disposed at the top side of the upper member and the bottom side of the lower member, and wherein each conductive contact member further comprises two mounting legs bilaterally downward or upward extending from the two opposite lateral rear sides of the elongated sheet portion for fastening to the corresponding catching grooves so as to effectively mount the conductive contact members onto the upper member and the lower member.

18. The electrical plug connector according to claim 1 , wherein the upper member defines an upper base portion and an upper tongue portion extending forward from the upper base portion in the rear-to-front direction, the lower member defines a lower base portion and a lower tongue portion extending forward from the lower base portion in the rear-to-front direction and the upper base portion of the upper member is engaged with the lower base portion of the lower member for production of an unitary member.

19. The electrical plug connector according to claim 18 , wherein a bottom side of the upper tongue portion and a top side of the lower tongue portion are parallel to each other and the mating room is formed between
