Abstract

A plug connector (100) includes a housing (1), a PCB (2) received in the housing, a cable set (7) electrically connecting with the PCB, a pulling member (32) moveable relative to the housing in a horizontal direction, a latch member (31) discrete from the pulling member and assembled to the housing for latch with a complementary connector, and a pull tape (33) discrete from the pulling member and assembled to the pulling member. The cable set includes a plurality of conductors (73, 74) connecting with the PCB, a metal braiding layer (72) forming a space and an outer jacket surrounding the metal braiding layer. A strain relief member (8) is assembled to the cable set and surrounded by the metal braiding layer.

Claims

1. A plug connector comprising:

a metal housing defining a receiving channel in a rear portion thereof and an exiting opening communicating with the receiving channel and the rear surface of the metal housing;

a plurality of conductive contacts located in the metal housing;

a cable set exiting from the exiting opening of the metal housing and comprising a plurality of conductors electrically connecting with the conductive contacts, a metal braiding layer shielding the conductors and partially exposed in the receiving channel, and an outer jacket surrounding the metal braiding layer; and

a strain relief member assembled to the cable set to locate between the outer jacket and the metal braiding layer of the cable set, and thus, the metal braiding layer and the strain relief member being received in the receiving channel and the metal braiding layer contacting the metal housing.

2. The plug connector as claimed in claim 1, wherein the strain relief member is a close member and comprises a hollow space having same periphery shape as that of the cable set.

3. The plug connector as claimed in claim 1, wherein the metal braiding layer is shaped to surround outer periphery of the strain relief member.

4. The plug connector as claimed in claim 3, wherein the metal braiding layer is soldered to the outer periphery of the strain relief member.

5. The plug connector as claimed in claim 1, the cable set comprises at least two cables juxtaposed arranged, and wherein each cable is according to Serial ATA standard.

6. The plug connector as claimed in claim 1, further comprising a transversely moveable latch member located on an exterior side of the metal housing, a pulling member associated with a rear portion of the latch member for transversely actuating the latch member, and a pull tape associated with a rear portion of the pulling member for selectively grasped.

7. The plug connector as claimed in claim 6, wherein the pulling member is stiff and the pull tape is soft.

8. The plug connector as claimed in claim 6, wherein the pulling member is moveable relative to the housing in a horizontal direction and comprises a front cooperating portion and a rear operating portion.

9. The plug connector as claimed in claim 8, wherein the latch member is discrete from the pulling member and is assembled to the housing for latching with a complementary connector, and wherein the latch member comprises an engaging portion assembled to the housing, an actuation section extending from the engaging section and capable of being actuated by the cooperating portion of the pulling member, and a front latching portion extending forwardly from at least one of the engaging portion and the actuation section for latching to the complementary connector

10. The plug connector as claimed in claim 8, wherein the latch member is vertically planted into a top surface of the base portion and the latching portion thereof partially extends beyond a front surface of the base portion to locate above the tongue portion.

11. The plug connector as claimed in claim 6, wherein the operating portion of the pulling member is exposed beyond the base portion of the housing and the pull tape is wholly exposed beyond the base portion of the housing.

12. The plug connector as claimed in claim 6, wherein the latch member is operated in a lever manner.

13. The plug connector as claimed in claim 9, wherein the engaging portion of the latch member locates in a vertical surface and the latching member locates in a horizontal surface, and wherein the housing comprises a base portion and a tongue portion extending from the base portion, the base portion defines a slit vertically extending a certain distance from a top surface thereof to receive the engaging portion of the latch member.

14. The plug connector as claimed in claim 9, wherein engaging portion is of n-shape and comprises a bar section from which the actuation section extends and a pair of side portions formed with barbs to interferentially engage with the slit.

15. The plug connector as claimed in claim 9, wherein the cooperating portion of the pulling member forms a slanted surface located below the actuation section of the latch member and capable of sliding along the actuation section to actuate the latching portion pivotally move relative to the engaging portion to separate from the complementary connector.

16. The plug connector as claimed in claim 1, further comprising a conductive shell assembled to the housing to partially shield the latch member and the pulling member.

17. The plug connector as claimed in claim 1, further comprising a PCB received in the housing, and wherein the contacts are first and second conductive pads formed at front and rear ends of the PCB.

18. A plug connector comprising:

a metal housing defining a receiving channel in a rear portion thereof;

a plurality of conductive contacts located in the metal housing;

a cable set comprising a plurality of conductors electrically connecting with the conductive contacts, said conductors being enclosed in an outer insulative outer jacket, a metal braiding layer shielding the conductors with thereof a front portion exposed in the receiving channel, and an outer jacket surrounding the metal braiding layer; and

a strain relief member assembled to the cable set to locate between the outer jacket and the metal braiding layer of the cable set, and thus, the metal braiding layer and the strain relief member being received in the receiving channel and the metal braiding layer contacting the metal housing.

19. The plug connector as claimed in claim 18, wherein the strain relief member is made of metal, and the metal braiding layer is directly fixed to said strain relief.

20. A plug connector comprising:

a metal housing defining a receiving channel in a rear portion;

a plurality of conductive contacts located in the metal housing;

a cable set comprising a plurality of conductors electrically connecting with the conductive contacts, said conductors being enclosed in an outer insulative outer jacket, a metal braiding layer shielding the conductors with a front portion exposed into the receiving channel of the housing, and an outer jacket surrounding the metal braiding layer; and

a metallic strain relief member assembled to the cable and fixed to the metal braiding layer and received in the receiving channel, wherein at least one of said strain relief member and said braiding layer directly mechanically and electrically contacts the metal housing.
