ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pair of connectors connected associated with a printed circuit board, particularly to a pair of connectors firmly located at opposite sides with respect to the printed circuit board and one of the connectors has board locks fixed to the printed circuit board.
2. The Prior Art
Electrical connectors are used popularly for interconnection between two electrical devices which may be mother boards, hard disk drivers or the like. The interconnection configurations of the connectors and the electrical devices may be different according to respective structural requirements of electrical systems. When a first connector is mounted on a printed circuit board, a second connector may be added on the first connector if only the two connectors are matingly adapted to each other. However, this kind of connection is not strong and stable enough, therefore this connection is apt to be loosened during transportation.
It is requisite to provide a new connector assembly which can guarantee stable interconnection between the connectors and the printed circuit board during transportation.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide a pair of connectors one of which is firmly fixed on a printed circuit board while the other of which is firmly fixed on the previous one connector.
One aspect of the present invention is to provide a connector assembly comprising a first connector and a second connector, with a printed circuit board located therebetween.
The first connector comprises a first housing having a cavity defined therein and two sockets formed at two ends of the first housing. The second connector comprises a second housing having a mating face and two side portions integrally connected to the second housing, each side portion having a first board lock and a second board lock extending upright.
The printed circuit board defines a first hole, two second holes symmetric to the first hole, and two third holes symmetric to the first hole. The second connector is fixed to the printed circuit board, wherein the first board lock is engaged with the third hole of the printed circuit board, the second housing of the second connector is retained in place by the first hole of the printed circuit board and a portion thereof extends beyond the printed circuit board. The second connector is fixed to the first connector, with the portion of the second housing of the second connector which extends beyond the printed circuit board is received in the cavity of the first connector and the second board lock is engaged within the socket of the first connector.
Another aspect of the present invention is to provide a connector assembly comprising a first connector and a second connector, with a printed circuit board located therebetween. The first connector comprises a first mating housing and a socket integrally connected to the first mating housing. The second connector comprises a second mating housing, a first board lock and a second board lock integrally connected to the second mating housing. The printed circuit board defines a first hole, a second hole and a third hole in such locations respectively corresponding to the locations of the second mating housing, the second board lock, and the first board lock. The second connector is fixed to the printed circuit board and the first connector by engaging the first board lock with the third hole of the printed circuit board, rendering the second mating housing of the second connector to be engaged with the first mating housing of the first connector, rendering the second board lock to extend through the second hole and finally to be retained in the socket of the first connector.
