Abstract

A power connector assembly (100) includes a plug (1) having a plurality of power pins (12) and signal pins (11) and a socket (2) receiving a plurality of contacts in a plurality of passageways (21, 25) thereof for engaging with corresponding signal pins and power pins. The signal pins of the plug are arranged in a plurality of parallel rows, each signal pin being staggered with other signal pins in a different row. The power pins are arranged at opposite sides of the signal pins and larger than the signal pins.

Claims

1. A power electrical connector assembly comprising:

a plug having a plug housing receiving a plurality of pins therein, the plurality of pins including power pins for transmitting power and signal pins for transmitting data, the signal pins being arranged in a plurality of rows, each row being parallel to others arid each signal pin being staggered with other signal pins in a different row, the power pins being arranged at opposite sides of the signal pins and each having a size larger than the signal pin; and

a socket having a socket hoising and a plurality of passageways receiving a plurality of contacts therein for engaging with corresponding power pins and signal pins of the plug, the arrangement of the passageways corresponding to that of the pins in the plug, the passageways including outmost passageways and middle passageways, the outmost passageways being designed to receive the power pins of the plug and the middle passageways being designed to receive the signal pins of the plug, each outmost passageway having a dimension larger than the middle passageway;

wherein

the plug housing has a bottom face defining a plurality of slots therein, the plurality of slots including a middle slot and two side slots;

wherein

the plug housing has side walls, the side walls defining a mating space therebetween for receiving the socket;

wherein

one of the side walls of the plug housing defines a notch therein communicating with the mating space, and wherein the socket housing has a protrusion for being correspondingly received in the notch to ensure a right engagement between the plug and the socket.

2. The power connector assembly as described in claim 1, wherein one end of the pin extending into the plug housing is a contacting portion and the other end of the pin extending outside the plug housing is a soldering portion, the soldering portions of the signal pins being positioned in the middle slot and the soldering portions of the flower pins being positioned in the side slots.

3. The power connector assembly as described in claim 1, wherein a post is formed on the bottom face of the plug housing and aligns with one of the power pins.

4. A power electrical connector assembly comprising:

a plug having a plug housing and a plurality of power pins and signal pins received in the plug housing, the signal pins being arranged in a plurality of rows parallel to each others each signal pin being staggered with other signal pins in a different row, the power pins being larger than the signal pins and positioned at outmost sides of the signal pins;

a socket having a socket housing defining a plurality of passageways therein and a plurality of contacts received in the passageways for engaging with one end of corresponding power pins and signal pins of the plug, the arrangement of the passageways corresponding to that of the pins in the plug, the passageways including outmost passageways and middle passageways, the outmost passageways being designed to receive the power pins and the middle passageways being designed to receive the signal pins, each outmost passageway having a dimension larger than the middle passageway; and

a printed circuit board defining a plurality of holes therein for engaging with the power pins and signal pins of the plug at the other end thereof opposite to the end contacting the contacts of the socket, the holes being arranged in a plurality of rows, the holes at outmost sides being larger than the others for receiving corresponding power pins;

wherein

the plug housing has a bottom race defining a plurality of slots therein, the plurality of slots including a middle slot and side slots, the power pins being positioned in the side slots and the signal pins being positioned in the side slots;

wherein the plug has side walls defining a mating space therebetween for receiving the socket, one of the side walls defining a notch communicating with the mating space, and wherein the socket provides a protrusion thereon for engaging with the notch.

5. The power connector assembly as described in claim 4, wherein the plug housing has a post formed on the bottom face thereof, and wherein the printed circuit board defmes an aperture for receiving the post, the post being aligned with one of the power pins.
