ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector assembly, and particularly to a board-to-board connector assembly for electrically interconnecting two circuit substrates such as printed circuit boards (PCBs).
2. Description of Prior Art
FIG. 7
shows a conventional board-to-board connector assembly
6
which is disclosed in Taiwan Patent Issue No. 371526. The connector assembly
6
comprises a first electrical connector
61
and a second electrical connector
62
. The first connector
61
comprises a first longitudinal insulative housing
610
, and a plurality of first electrical terminals
612
received in the first housing
610
. The first housing
610
defines a longitudinal cavity therein. A pair of first end walls
614
is defined at opposite ends of the cavity respectively. The second connector
62
comprises a second longitudinal insulative housing
620
, and a plurality of second electrical terminals
622
received in the second housing
620
. The second housing
620
defines a longitudinal slot
624
therein. An island
626
is formed in the slot
624
, and a pair of second end walls
628
is formed at opposite ends of the slot
624
respectively. When the first connector
61
and the second connector
62
are connected or disconnected at a slight angle, the first end walls
614
interfere with respective major portions of the second end walls
628
that are distal from a main body of the second housing
620
. The first end walls
614
also interfere with a major portion of the island
626
that is distal from a main body of the second housing
620
. Because of friction between the first end walls
614
and said major portions of the second end walls
628
, and of friction between the first end walls
614
and said major portion of the island
626
, the first connector
61
cannot be smoothly and conveniently connected to or disconnected from the second connector
62
. Thus, the first end walls
614
, the second end walls
628
and the island
626
are prone to be damaged.
Another conventional board-to-board connector assembly which is disclosed in U.S. Pat. No. 6,159,021 is similar to the conventional board-to-board connector assembly
6
described above, except that a second electrical connector does not have a pair of second end walls. When a first connector and the second connector are connected or disconnected at a slight angle, first end walls of the first connector interfere with a major portion of an island of a second housing of the second connector that is distal from a main body of the second housing. Because of friction between the first end walls and said major portion of the island, the first connector cannot be smoothly and conveniently connected to or disconnected from the second connector. Thus, the first end walls and the island are prone to be damaged.
In view of the above, a new board-to-board connector assembly that overcomes the above-mentioned disadvantages is desired.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connector assembly such as a board-to-board connector assembly for electrically interconnecting two circuit substrates such as printed circuit boards (PCBs) such that when connectors of the connector assembly are connected or disconnected, interference therebetween is minimized.
To achieve the above-mentioned object, a board-to-board connector assembly in accordance with a preferred embodiment of the present invention is for electrically interconnecting two PCBs. The connector assembly comprises a first electrical connector and a second electrical connector. The first connector comprises a first longitudinal insulative housing, and a plurality of first electrical terminals received in the first housing. The first housing defines a longitudinal slot therein. An island is formed in the slot, and a pair of first end walls is formed at opposite ends of the slot respectively. The second connector comprises a second longitudinal insulative housing, and a plurality of second electrical terminals received in the second housing. The second housing defines a longitudinal cavity for receiving the island of the first connector therein. A pair of second end walls is formed at opposite ends of the cavity. Each second end wall defines an opening in a portion thereof distal from a main body of the second housing. Each second end wall also defines a recess adjoining an outer main face thereof. When the first and second connectors are connected or disconnected at a slight angle relative to each other, interference therebetween can be eliminated.
