ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector assembly, and more particularly to a stacked modular jack connector assembly in which two modular jacks are mirror-image arranged.
2. Brief Description of the Prior Art
U.S. Pat. No. 5,531,612 discloses a conventional modular jack connector assembly. The modular jack connector assembly comprises a common main housing and a plurality of modular jack connectors mounted within the main housing. The modular jack connectors are provided in upper and lower rows in a substantially mirror image disposition. The main housing is integrally formed. Each modular jack has an insert assembly which is consisted of a first over-moulded portion for securing engaging ends of contacts thereof and a second over-moulded portion for securing soldering tails of the contacts thereof.
It can be seen that the conventional connector requires extra manufacturing of the insert assemblies thereof. Moreover, the integral main housing makes the conventional connector can not be adapted for different mounting panels.
Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide a modular jack connector assembly with a retention means reliably spacing and retaining a plurality of terminals thereof; and
A second object of the present invention is to provide a modular jack connector assembly with a retention means facilitating an assembly thereof.
To achieve the above-mentioned objects, a modular jack connector assembly includes a first jack overlapping on a second jack. The first jack has a first housing and a plurality of first terminals extending through the first housing. The first housing is consisted of an upper section and a lower section offsetting from the upper section whereby defining a space. The lower section defines a pair of openings, a plurality of partitions at an underside thereof and a plurality of spaced recesses divided by the partitions. A plurality of integrally formed toes projects forwardly from an underside of the lower section. The upper section has a pair of lead-ins downwardly projecting from a bottom side thereof.
The second jack includes a housing, a plurality of second terminals extending through the housing, a pair of channels at lateral sides of a top end thereof, a pair of latches extending from a rear side thereof, a plurality of projections extending rearwardly from a rearward underside thereof, and a plurality of grooves defined by the projections. Some of the second terminals extend along the partitions while other second terminals bend inwardly into the grooves. The latches and the partitions are integrally formed with a housing of the second jack.
In assembly, the second jack is inserted into the space by means that the channels slide along the lead-ins to guide and secured the second jack. The latches then extend into the openings. As a result, the projections fit with the recesses and the grooves mate with the toes whereby the second terminals are reliably positioned between corresponding projections and recesses or between corresponding toes and grooves. The connector is finally mounted onto a circuit board.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
