ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical connector, and particularly to an electrical connector having a shield interferentially secured thereto.
BACKGROUND OF THE INVENTION
It is well known in the electrical connector field, particularly in the high frequency communications connector field, that metal shells can be used to enclose a dielectric housing and a plurality of contacts received in the housing, thereby reducing the effects of external electromagnetic interference on the signal transmitted through the connector. There are many ways to connect the metal shell to a reference potential such as a grounding point. One way is to form several tabs on the metal shell which electrically connect to a grounding plate of the connector, which in turn electrically connect to the reference potential. The grounding tabs must provide an adequate normal force to ensure that free ends thereof reliably contact the grounding plate. In order to attain adequate normal force, the metal shell is usually formed by first stamping a metal plate to get a flat shell and then bending the flat shell to get a final shell. The final shell usually comprises a portion having two or more layers of plates stacked one above the other, which adds significantly to the height of the connector. This is unacceptable for a mini cable connector, which must have only a very limited height. An improved low profile mini coaxial cable connector is desired to overcome the disadvantages of the prior art. Hence, an improved shield for an electrical connector is required to overcome such disadvantages.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a shield for an electrical connector wherein the shield is firmly secured to the connector using interferential means.
Another object of the present invention is to provide a shield which is simple in design and easy to manufacture.
To fulfill the above-mentioned objects, an electrical connector in accordance with the present invention comprises an elongated insulative housing with a plurality of terminals secured therein, and a shield having a first portion and a second portion firmly secured to the housing. The housing defines a pair of channels in both a front and rear faces thereof, and a pair of slots in end faces thereof. The first portion and the second portion respectively form a pair of front tangs and a pair of rear tangs extending upwardly therefrom for engaging in the channels. A pair of side hooks with engaging fingers extends from opposite edges of the first portion for engaging with the slots, thereby securing the first portion to the front side of the housing. A pair of side plates each with a securing latch secures the second portion tightly to the rear side of the housing.
The first portion and the second portion of the shield of the preferred embodiment of present invention are integrally formed from a metal plate.
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.
