ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical connector assembly, and more particularly to an assembly having a first connector and a second connector mated to the first connector. Interconnection between the first and second connectors is affirmed by a strain relief having a pair of first latches secured to the second connector and a pair of second latches releasably secured to the first connector.
DESCRIPTION OF PRIOR ART
Conventionally, an IDC connector assembled to an end of a cable is directly plugged to a complimentary connector (normally a header connector) mounted on a printed circuit board. The termination between insulation displacement portions and conductors of the cable is facilitated by a termination cover assembled to the housing of the IDC connector. In order to prevent the termination from being accidentally separated during withdraw of the IDC connector from the header, one of the approach is to provide a strain relief assembled to the termination cover thereby preventing the termination from being damaged during removal of the IDC connector.
Another approach addressed to this problem is to provide a pull-tab assembled to the termination cover. This may also prevent the termination from being separated during removal of the IDC connector.
However, it is desired to ensure the connection between the IDC connector and the header. Therefore, a latch which is easily operated, is expected to be used with an IDC/header connector assembly.
SUMMARY OF THE INVENTION
An objective of this invention is to provide an electrical connector assembly having a first connector and a second connector mated to the first connector. Interconnection between the first and second connectors is affirmed by a strain relief having a handle by which outer latches thereof can be securely fixed in a locked position.
Another objective of this invention is to provide an electrical connector assembly wherein a handle is provided to bridge a pair of outer latches thereby facilitating easy unhook and pull out of the second connector with respect to the first connector.
In order to achieve the objectives set forth, an electrical connector assembly comprises a first connector and a second connector mated to the first connector. A strain-relief device is assembled to the second connector for releasably attaching the second connector the first connector. The device includes a base bar having a pair of inner latches extending downward from opposite ends thereof for fixedly engaging with said second housing, a pair of outer latches pivotally attached to said bar for releasably engaging with said mounting recesses of said first housing, a flexible handle bridged between rear ends of said outer latches. When the handle is pulled upward, the outer latches are released from the mounting recesses and further providing easy separation of the second connector with respect to the first connector.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiment of the invention taken in conjunction with the appended drawings.
