ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a receptacle connector for high frequency signal transmission, and in particular to a receptacle connector having a secure EMI shield and which can durably withstand frequent connection/disconnection with a mating connector.
2. The Prior Art
Electrical connectors for high frequency signal transmission are normally provided with shielding means, usually made of metallic material, in order to alleviate or eliminate problems arising from EMI. Examples of EMI shielding designs are disclosed in US Design No. 345,343 and Taiwan patent application Nos. 81110335, 81217896 and 81302112. Conventionally, a shielding member is stamped from a metal sheet, which usually produces a large amount of metal waste in mass production.
Hence, it is desirable to have a receptacle connector having a two piece shielding device which overcomes the problem of excess metal waste encountered in the prior art, while maintaining excellent shielding properties and having a durable structure for ensuring a long service life.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a receptacle connector having a shielding device comprising two separate members electrically engaged with each other for reducing the amount of metal waste generated during a manufacturing process thereof.
Another object of the present invention is to provide a receptacle connector having excellent electromagnetic interference shielding properties.
A further object of the present invention is to provide a receptacle connector having a shielding member with an extended service life.
Still another object of the present invention is to provide a receptacle connector having a durable shielding member which can withstand frequent engagement/disengagement between the receptacle connector and a mating plug connector.
To achieve the above objects, a receptacle connector in accordance with the present invention comprises an insulative housing defining a receptacle chamber adapted for receivably engaging a mating connector. A plurality of pins are retained in the chamber by means of a spacer. A front shielding shell has a connector engaging section for engaging the mating connector and two side plates extending from the connector engaging section to be fixed to two side faces of the housing thereby securing the front shell to the housing. A rear shielding shell has a U-shaped configuration for covering and being secured to the housing and for electrically engaging the front shell. The rear shell has a cantilevered arm having a resilient curved section with a convex portion partially received in the receptacle chamber for electrically engaging a grounding member of the mating connector. The curved section has a free end supported on a top face of the housing for providing a more durable structure.
