Abstract

A power connector (1) includes an insulative housing (2), a first conductive contact (5) and a second conductive contact (6). The insulative housing includes a receiving space (3) defined inwardly from a front surface of the housing and an inner portion (22) bounded on its sides by the receiving space. Each contact includes a main body (51, 61) assembled in the rear wall of the housing and a plurality of mating portions (53, 63). The mating portions are assembled in the housing and partly exposed in the receiving space. The mating portions of the first conductive contact are arranged on an outer circle. The mating portions of the second conductive contact are arranged on an inner circle inside the outer circle.

Claims

1. A power connector for being mounted to a printed circuit board, comprising:

an insulative housing including a receiving space defined rearwardly from a front surface of the insulative housing and an inner portion extending from a rear wall of the housing and bounded on its sides by the receiving space;

a first conductive contact and a second conductive contact, each of the first and second contacts comprising a main body assembled in the rear wall of the housing and a plurality of mating portions integrally formed with the main body adapted for engaging with a contact of a mating connector, the mating portions assembled in the housing and partly exposed in the receiving space, the mating portions of the first conductive contact arranged on an outer circle and the mating portions of the second conductive contact arranged on an inner circle inside the outer circle.

2. The power connector as described in claim 1, wherein a first receiving slot is defined in the rear wall of the housing, and the main body of the first conductive contact is received in the first receiving slot, a second receiving slot is also defined in the rear wall of the housing, and the rectangular main body of the second conductive contact is received in the second receiving slot.

3. The power connector as described in claim 2, wherein the first receiving slot is annular, and the second receiving slot is rectangular.

4. The power connector as described in claim 3, wherein the first receiving slot locates in a periphery of the rear wall of the housing, and the second receiving slot locates in a core of the rear wall of the housing.

5. The power connector as described in claim 2, wherein four first holes are defined in the rear wall of the housing and in communication with the first receiving slot, the first holes extend forwardly from the rear wall of the housing toward the front surface of the housing.

6. The power connector as described in claim 5, wherein four first grooves in communication with the first receiving slot are defined in an inner surface of the housing, and extend forwardly from the rear wall of the housing, and the four mating portions of the first conductive contact extend through the first holes and are received in the first grooves.

7. The power connector as described in claim 6, wherein the mating portions of the first conductive contact extend forwardly from the main body and are arranged in equal intervals.

8. The power connector as described in claim 7, wherein each mating portion of the first conductive contact bends inwardly and partly protrudes from a corresponding first groove into the receiving space.

9. The power connector as described in claim 7, wherein four second holes in communication both with the second receiving slot and the receiving space are defined in the rear wall of the housing, and extend forwardly through the rear wall and generally parallel to a top, a bottom and two side walls of the housing.

10. The power connector as described in claim 9, wherein corresponding to the orientations of the second holes, four second grooves in communication with the second receiving slot are defined in an outer surface of the inner portion, and extend forwardly from the rear wall of the housing, and the mating portions of the second conductive contact protrude through the second holes and received in the second grooves, the second conductive contact having barbs engaging with the inner portion.

11. The power connector as described in claim 10, wherein each mating portion of the second conductive contact bends outwardly and partly protrudes from the second grooves into the receiving space.

12. The power connector as described in claim 11, wherein the mating portions of the second conductive contact extends forwardly from a top, a bottom, a left side and a right side of the main body thereof, respectively, and are arranged in equal intervals.

13. The power connector as described in claim 1, wherein the first conductive contact further includes a pair of feet for solder connection to the printed circuit board, extending downwardly from a bottom front edge and a bottom rear edge of the main body of the first conductive contact, each foot defining a short slot therein.

14. The power connector as described in claim 1, wherein the second conductive contact further includes a pair of legs extending downwardly from opposite sides of the main body thereof, and a pair of feet extending downwardly from lower ends of the pair of legs for solder connection to the printed circuit board and each foot of the second conductive contact defining a short slot therein.

15. The power connector as described in claim 1, wherein a receiving hole is defined along a longitudinal axis of the inner portion and communicates with a central slot defined through the rear wall and into the inner portion of the insulative housing.

16. The power connector as described in claim 15, wherein the power connector further comprises a conductive signal pin comprising a mating portion received in the receiving hole, a mounting portion extending downwardly from the mating portion and received in the central slot for being mounted to the printed circuit board.

17. The power connector as described in claim 1, wherein the conductive shield further comprises a pair of lock tabs extending inwardly and upwardly from a lower edge of each of two sidewalls thereof, the lick tabs respectively locking into slots in a bottom wall of the housing.

18. An electrical connector for use with a complementary connector, comprising:

an insulative housing defining thereof opposite front and rear faces with an inner central receiving portion and an outer circumferential receiving space;

a center contact located in the inner central receiving portion; and

an outer contact assembly located in the outer circumferential receiving space;

wherein

said outer contact assembly defines two groups of mating fingers, of which one is arranged in an inner circle and the other is arranged in an outer circle, said inner circle and said outer circle together defining a gap adapted for receiving a sleeve-like contact of said complementary connector therein.

19. The connector as described in claim 18, wherein said two groups of mating fingers are alternately located circumferentially.

20. The connector as described in claim 18, wherein said two groups of mating fingers belong to two discrete pieces.
