ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a modular jack, and particularly to a modular jack exhibiting excellent grounding capabilities.
DESCRIPTION OF THE PRIOR ART
As the trend of the computer industry leads toward miniaturization, electrical connectors of reduced size are desired. Conventional modular jacks disclosed in U.S. Pat. Nos. 5,069,641; 5,587,884; and 5,647,766 provide a port for receiving a mating connector. However, such modular jacks are not suitable for high capacity signal transfer applications. U.S. Pat. No. 5,647,767 discloses a modular jack having three stacked ports to promote high capacity signal transfer. However, the modular jack does not provide an effective grounding shield for preventing cross-talk. 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 comprising at least an RJ45 connector and a stacked USB connector;
A second object of the present invention is to provide a modular jack exhibiting excellent grounding capabilities.
Accordingly, a modular jack comprises a dielectric frame, a daughter board having a RJ45 connector and a transformer mounted thereon, a stacked USB connector and first and second shields enclosing the frame and the daughter board. The daughter board includes a grounding pad on a surface thereof on which the RJ45 connector is mounted. The stacked USB connector has a grounding shell mounted on a rear portion thereof. The frame forms a horizontal partition and a vertical partition. The frame defines a first space and a second space separated by the horizontal partition. The vertical partition defines a slot. The first and stacked USB connectors are received in the first and second spaces, respectively, with the daughter board abutting against the vertical partition and the grounding pad extending through the slot to electrically connect with the grounding shell of the stacked USB connector.
The first shield comprises a rear plate and a pair of side plates. The rear plate defines a slit proximate a top edge thereof. Each side plate forms a pair of bosses proximate an edge thereof distanced from the rear plate. The second shield comprises a top plate and a front plate. The top plate forms a hook downwardly extending from an edge thereof distanced from the front plate. The front plate defines a pair of cutouts in each opposite side edge thereof. The hook is received in the slit and the cutouts receive the corresponding bosses to engage the first and second shields together.
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.
