ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to a mini coaxial cable connector having a relatively low profile.
2. Brief Description of the Prior Art
It is well known in the electrical connector field, particularly in the high frequency communication connector field, that metal shells can be widely used to enclose a dielectric housing and a plurality of contacts received in the housing for 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 to the earth. 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 obtain adequate normal force, the metal shell is usually stamped and formed by first stamping a metal plate to get a flat shell and then by bending the flat shell to get a final shell. The final shell usually comprises a portion having two or more layers of plate stacked one above the other, which adds significantly to profile height of the connector. This is unacceptable for a mini cable connector, which must have only a very limited profile height. Hence, an improved low profile mini coaxial cable connector is required to overcome the disadvantages of the prior art. The U.S. Pat. No. 6,123,582 issued Sep. 26, 2000 with the same inventor and the same assignee discloses the related art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide a mini coaxial cable connector having a very low profile;
A second object of the present invention is to provide a low profile mini coaxial cable connector having a grounding shell providing grounding tabs which provide adequate normal force against a grounding plate of the cable connector thereby providing a reliable electrical connection thereto.
To achieve the above-mentioned objects, a low profile mini coaxial cable connector of the present invention includes a dielectric housing, a contact set and a cable set electrically connected together, a grounding plate and a metal shell. The contact set, the cable set and the grounding plate are fixedly accommodated in the housing and the metal shell encloses the housing. The metal shell has two grounding tabs electrically contacting the grounding plate. The metal shell has an upper flap, a lower flap and two side flaps extending from the upper flap which do not engage with the lower flap but are flash with side edges of the lower flap. The housing forms two buds on two side surfaces thereof and each of the two side flaps of the metal shell defines a notch fixedly engaging with a corresponding bud of the housing thereby reliably fixing the metal shell to the housing and developing adequate normal force between the grounding tabs and the grounding plate.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
