Abstract

An plug connector assembly ( 1 ) includes a mating member ( 10 ) including a front mating end ( 101 ) and a rear mating end ( 102 ), a cable ( 30 ) electrically connected with the mating member, a first shell ( 50 ) formed by sheet metal drawing and having a closed circumference, a second shell ( 60 ) formed by sheet metal drawing and having a closed circumference. The first shell includes a first front end ( 51 ) telescoped with the rear mating end, and a first rear end ( 52 ) opposite to the first front end. The second shell ( 60 ) includes a second front end ( 61 ) telescoped with the first rear end, and a second rear end ( 62 ) opposite to the second front end and telescoped on the cable.

First claim

What is claimed is:

1. A plug connector assembly adapted for mating with a mating connector, comprising:
a mating member comprising a front mating end for being inserted into the mating connector, and a rear mating end opposite to the front mating end;
a cable electrically connected with the mating member;
a first shell formed by sheet metal drawing, the first shell having a closed circumference, the first shell comprising a first front end telescoped with the rear mating end, and a first rear end opposite to the first front end; and
a second shell formed by sheet metal drawing, the second shell having a closed circumference, the second shell comprising a second front end telescoped with the first rear end, and a second rear end opposite to the second front end and telescoped on the cable;
wherein the mating member comprises an insulative housing, a plurality of first contacts arranged in two rows and spaced apart from each other in a vertical direction, and a latch disposed between the two rows of contacts for latching with the mating connector.

2. The plug connector assembly as recited in claim 1 , wherein the mating member comprises an insulative member disposed behind the insulative housing, the insulative member restricting the latch to cooperate with the insulative housing.

3. The plug connector assembly as recited in claim 1 , further comprising a printed circuit board disposed between the mating member and the cable for electrically connecting the cable and the mating member.

4. The plug connector assembly as recited in claim 1 , wherein the first front end has a diameter smaller than a diameter of the first rear end, the first shell comprising a first transition portion connecting with the first front end and the first rear end.

5. The plug connector assembly as recited in claim 4 , wherein the second front end has a diameter larger than a diameter of the second rear end, the second shell comprising a second transition portion connecting with the second front end and the second rear end.

6. The plug connector assembly as recited in claim 1 , wherein the second front end is laser beam welded to the first rear end.

7. The plug connector assembly as recited in claim 1 , wherein one of the first rear end and the second front end comprises a latch tab, and the other one of the first rear end and the second front end comprises a latch hole latched with the latch tab.

8. A plug connector assembly adapted for mating with a mating connector, comprising:
a mating member comprising a front mating end for being inserted into the mating connector, and a rear mating end opposite to the front mating end;
a cable electrically connected with the mating member;
a spacer comprising a first portion and a second portion disposed behind the first portion, the second portion having a diameter larger than a diameter of the first portion;
a first shell having a closed circumference, the first shell comprising a first front end telescoped with the rear mating end, and a first rear end opposite to the first front end; and
a second shell having a closed circumference, the second shell comprising a second front end telescoped with the first rear end, and a second rear end opposite to the second front end and telescoped on the cable;
wherein the first rear end is telescoped on the first portion of the spacer, and the second front end is slid over the second and telescoped on an outer side of the first rear end.

9. The plug connector assembly as recited in claim 8 , wherein a gap exists between the second portion and the first portion of the spacer and is larger than or equal to a thickness of the circumference of the first shell.

10. The plug connector assembly as recited in claim 8 , wherein the second front end interference fits with an outer side of the first rear side.

11. The plug connector assembly as recited in claim 8 , wherein the second front end is laser beam welded with the first rear end.

12. The plug connector assembly as recited in claim 8 , wherein the cable comprises a plurality of wires organized by the spacer.

13. The plug connector assembly as recited in claim 12 , wherein the spacer comprises an upper portion and a lower portion each defining a plurality of through holes, the wires received in and restricted by the through holes.

14. The plug connector assembly as recited in claim 8 , wherein the mating member comprises a third shell having a closed circumference, the first front end laser beam welded with the third shell.

15. A cable connector assembly comprising:
a mating member extending along a front-to-back direction and including an insulative housing enclosed within a capsular metallic front shell which is essentially configured as a tubular structure via a drawing process in a seamless manner thereof;
a plurality of terminals disposed in the housing with corresponding contacting sections exposed to a receiving room in the housing;
a printed circuit board located behind the housing, along said front-to-back direction, with tails of said terminals mounted upon a front region thereof;
a metallic middle shell located behind the front shell along said front-to-back direction and surrounding the printed circuit board, said middle shell being essentially configured as another tubular structure via another drawing process in the seamless manner; wherein the front shell includes a rear connection end and the middle shell includes a front connection end snugly circumferentially connected to the rear connection end, and one of said rear connection end and said front connection end includes a latch to be engaged with the other so as to retain the front shell and the middle shell with each other without relative movement in said front-to-back direction; and
a cable enclosing a plurality of wires connected to a rear region of the printed circuit board, and a metallic rear shell located behind the middle shell to enclose said cable, wherein said rear shell is essentially configured as another tubular structure via another drawing process in the seamless manner, a front connection end of the rear shell is snugly circumferentially connected to a rear connection end of the middle shell.

16. The cable connector assembly as claimed in claim 15 , wherein all said front shell, said middle shell and said rear shell are linked with one another in sequence along said front-to-back direction in roughly a telescopic manner.

17. The cable connector assembly as claimed in claim 15 , wherein in the middle shell, the front connection end is smaller than the rear connection end.

18. The cable connector assembly as claimed in claim 17 , wherein the front connection end of the middle shell is located outside of the rear connection end of the front shell, and the rear connection end of the middle shell is located outside of the front connection end of the rear shell.
