Abstract

A connector assembly (1) to usually form a power part of a backplane connector assembly comprises an electrical connector (2) and a mating complementary connector (3). The connector (2) has an insulated housing (20) and a plurality of power conductors (21) installed inside the housing (20), and the complementary connector (3) has an insulated housing (30) and a plurality of complementary conductors (31, 32) installed inside the housing (30). At least one conductor (23) of the connector (2) and its complementary conductor (32) of the complementary connector (3) are arranged beside other conductors (22, 31) while other conductors (22) of the connector (2) and other complementary conductors (31) are arranged in the same rows respectively. Controllable electrical property and maximum current carrying capacity of the conductors in the connector assembly is easily acquired due to the specially arranged conductors. And the size of the connector assembly can be compact to meet the need of structural simplification and become easier to be assembled with other backplane connector parts.

Claims

1. A connector assembly comprising:

a first electrical connector having a first housing and a plurality of first conductors installed in the first housing; and

a second electrical connector configured to be mated with the first electrical connector and having a second housing mated with the first housing and a plurality of second conductors being installed in the second housing and electrically connecting to corresponding first conductors of the first electrical connector;

at least one of the plurality of the first conductors having installation orientation different from that of some other of the plurality of the first conductors, and the at least one of the plurality of the first conductors having a resistance equal to that of each of said some other of the plurality of the first conductors;

wherein

said some other of the plurality of the first conductors are arranged in one row and each of said some other of the plurality of the first conductors is located in respective one plane of a first group of parallel-arranged imaginary planes;

wherein

said at least one of the plurality of the first conductor has a contacting portion located in a second imaginary plane perpendicular to any of the first group of parallel-arranged imaginary planes;

wherein

said at least one of the plurality of the first conductors is an L-shaped plate and stamped from one metal sheet;

wherein

said at least one of the plurality of the first conductors has several tail portions extending vertically from the contacting portion thereof and located in a third imaginary plane perpendicular to both the first parallel plane group and the second imaginary plane;

wherein

the second conductors of the second electrical connector are identically shaped at least one of the plurality of the second conductors is located in the second imaginary plane when the second electrical connector is mated with the first electrical connector.

2. The connector assembly as recited in claim 1, wherein each of said some other of the plurality of the first conductors of the first electrical connector is of a plate-like configuration and defines one imaginary plane of the first parallel plane group.

3. A connector assembly comprising:

a first connector adapted to be mounted upon a first printed circuit board;

a second connector mated with the first connector and adapted to be mounted upon a second printed circuit board perpendicular to said first printed circuit board;

said first connector defining at least a first set of first contact sections and a second set of first contact sections both of an identical configuration and extending straightly toward the second connector while perpendicular to each other;

said second connector defining a first set of second contact sections and a second set of second contact sections, said first set of second contact sections being located closer to the second printed circuit board than the second set of second contact sections;

each of the first set of second contact sections extending in a first plane, and each of said second set of second contact sections extending in successive second and third planes both of which are perpendicular to said first plane;

wherein

said second plane is parallel to said second printed circuit board said third plane is parallel to said first printed circuit board, and said first plane is perpendicular to both said first printed circuit board and said second printed circuit board;

wherein

each of the first and the second sets of the first contact sections comprises pairs of contacting portions and a plurality of tail portions opposite to the contacting portions, and wherein each contacting portion of the same pair is bent away from each other;

wherein

each of the second set of the second contact sections is an L-shaped plate and comprises a top plate section extending in the second plane and a lateral plate section extending in the third plane.

4. The connector assembly as recited in claim 3, wherein each of the first set of the first contact sections extends in the first plane, and each of the second set of the first contact sections extends in the second plane.

5. The connector assembly as recited in claim 3, wherein each of the first set of the second contact sections has a same resistance as each of the second set of the second contact sections.
