ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electrical connector, and particularly to a low profile electrical connector for mounting in a cutout in an edge of a printed circuit board.
2. Description of the Related Art
To protect electrical connectors from Electro Magnetic Interference (EMI), a metal shield enclosing a housing is often provided. The housing and the metal shield must remain in fixed positions relative to each other, particularly in environments subject to vibration. The metal shield is often constructed in two halves with a cooperating latching system being formed on both halves for securing each half together with the housing. A related electrical connector having a shield as described is shown in
FIGS. 5 and 6
. The shield includes a first shield
62
and a second shield
63
. More manufacturing steps and cost and greater coordination during assembly are required for such two-part shields, as opposed to a single piece shield. Additionally, an engagement between an opening
64
defined in the first shield
62
and a protrusion
65
formed on a housing
61
can not prevent the first shield
62
from being vertically displaced relative to the housing
61
.
Hence, an improved electrical connector is required to overcome the abovementioned problems.
BRIEF SUMMARY OF THE INVENTION
Accordingly, an objective of the present invention is to provide an electrical connector with a one-piece shield which encloses a housing and shields the housing from EMI and which can not be displaced relative to the housing in a perpendicular direction.
A further objective of the present invention is to provide an electrical connector which is easy to manufacture and assemble.
To fulfill the above-mentioned objectives, a board mounted electrical connector in accordance with the present invention comprises an insulative housing, a one-piece shield, a terminal insert retaining a plurality of terminals therein and a pair of light emitting diodes (LEDs). The insulative housing is substantially rectangular and defines a receiving space for receiving the terminal insert and a mating connector therein. The one-piece shield comprises a first shield portion and a second shield portion extending from a rear edge of the first shield portion. A pair of protruding portions outwardly projects from side walls of the housing and a groove is defined in a front side edge of each protruding portion. A pair of support tabs, each defining a notch at a rear side thereof, are formed at opposite sides of the first shield portion for engaging with the protruding portions. Each support tab abuts against a lower edge of a corresponding protruding portion, and fits in the groove of the corresponding protruding portion, thereby preventing a vertical displacement of the shield and preventing the opposite sides of the first shield portion from springing outwardly.
