Electrical adapter

Claim 2

An electrical adapter comprising: a first connector configured with a Serial Advanced Technology Attachment (Serial ATA) interface and comprising a first and a second mating ports; a second connector configured with a Serial ATA interface thereof and connected to the first mating port of the first connector for providing signal transmission therebetween; and a third connector configured as a conventional power connector and electrically connected to the second mating port of the first connector for providing power transmission therebetween; wherein the first and second mating ports are arranged in a side-by-side manner; wherein the first mating port has a smaller dimension than the second mating port in a lengthwise direction thereof; wherein the first connector is a Serial ATA receptacle connector, the second connector is a Serial ATA plug connector and the third connector is a conventional power plug connector; wherein the electrical adapter comprises a printed circuit board disposed between the first connector and the third connector.

Claim 3

An electrical adapter comprising: a first connector comprising a first insulating housing and a plurality of first and second contacts retained to the first housing, each first contact comprising a first engaging portion received in the first housing and an opposite second engaging portion; a second connector back to back assembled to the first housing and receiving the second engaging portions of the first contacts therein; and a third connector comprising a third insulating housing back to back assembled to the first housing and a plurality of third contacts different from and electrically connected with the second contacts of the first connector; wherein the first connector is configured with a Serial Advanced Technology Attachment (Serial ATA) interface; wherein the first housing defines first and second mating ports, and the first and second contacts are respectively received in the first and second mating ports; wherein the first and second mating ports of the first connector are arranged in a side-by-side manner; wherein the first contacts are signal contacts and the second contacts are power contacts; wherein said second contacts and said third contacts are electrically connected via a printed circuit board sandwiched between said first and third connectors; wherein said first connector includes, along a lengthwise direction thereof, an elongated base which the first and second mating ports integrally extend from on one side thereof, and the juxtaposed second and third connectors are, on the other side thereof, attached to, respectively, along said lengthwise direction.

Claim 4

An electrical adapter comprising: a first connector comprising a first insulating housing and a plurality of first and second contacts retained to the first housing, each first contact comprising a first engaging portion received in the first housing and an opposite second engaging portion; a second connector back to back assembled to the first housing and receiving the second engaging portions of the first contacts therein; and a third connector comprising a third insulating housing back to back assembled to the first housing and a plurality of third contacts different from and electrically connected with the second contacts of the first connector; wherein the first connector is configured with a Serial Advanced Technology Attachment (Serial ATA) interface; wherein the first housing defines first and second mating ports, and the first and second contacts are respectively received in the first and second mating ports; wherein the first and second mating ports of the first connector are arranged in a side-by-side manner; wherein the first contacts are signal contacts and the second contacts are power contacts; wherein said second contacts and said third contacts are electrically connected via a printed circuit board sandwiched between said first and third connectors; wherein said first connector includes, along a lengthwise direction thereof, an elongated base which the first and second mating ports integrally extend from on one side thereof, and the juxtaposed second and third connectors are, on the other side thereof, attached to, respectively, along said lengthwise direction.

Claim 5

An electrical adapter comprising: a first connector comprising a first housing defining a first and a second mating ports respectively receiving a plurality of first and second contacts therein, each second contact comprising a press-fit portion; a second connector back to back assembled to the first housing; a third connector comprising a third housing back to back assembled to the first housing and a plurality of third contacts retained in the third housing; and a printed circuit board disposed between the first and third housings with the third contacts soldered thereto and the press-fit portions of the second contacts press-fitted into thereto; wherein each first contact comprises a first engaging portion received in the first housing for electrical connection with a first complementary connector, and an opposite second engaging portion received in the second connector for electrical connection with a second complementary connector; wherein the second contacts and the third contacts have different numbers and different positions relative to each other; wherein the first connector and the second connector define locking and positioning members for back-to-back assembling the first connector and the second connector together; wherein the first connector and the third connector define locking and positioning members for back-to-back assembling the first connector and the third connector together; wherein the third housing defines a plurality of cutouts, and the press-fit portion of the second contacts have terminating ends received in the corresponding cutouts.

Claim 6

An electrical adapter comprising: a first connector comprising a first housing defining a first and a second mating ports respectively receiving a plurality of first and second contacts therein, each second contact comprising a press-fit portion; a second connector back to back assembled to the first housing; a third connector comprising a third housing back to back assembled to the first housing and a plurality of third contacts retained in the third housing; and a printed circuit board disposed between the first and third housings with the third contacts soldered thereto and the press-fit portions of the second contacts press-fitted into thereto; wherein each first contact comprises a first engaging portion received in the first housing for electrical connection with a first complementary connector, and an opposite second engaging portion received in the second connector for electrical connection with a second complementary connector; wherein the second contacts and the third contacts have different numbers and different positions relative to each other; wherein the first connector and the second connector define locking and positioning members for back-to-back assembling the first connector and the second connector together; wherein the first connector and the third connector define locking and positioning members for back-to-back assembling the first connector and the third connector together; wherein the third housing defines a plurality of cutouts, and the press-fit portion of the second contacts have terminating ends received in the corresponding cutouts.
