ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an electrical card connector used for mobile communications, and particularly to an electrical card connector for connecting an electrical card to a printed circuit board.
BACKGROUND OF THE INVENTION
Electrical card connectors are popularly used in mobile communications for connecting electrical cards to printed circuit boards Conventional electrical card connectors are disclosed in U.S Pat. Nos. 5,996,891, 5,984,707, 5,961,338, 5,603,629 and 5,320,552. Covers and bases of conventional electrical card connectors have a high profile to obtain a certain degree of strength. The high profile causes problems during injecting molding, such as uneven shrinkage.
To guarantee sufficient mechanical strength while obtaining a smaller profile, material having good mechanical strength and ability to flow as a liquid is required. However, this combination may still result in the appearance of defects caused by the liquid material failing to completely fill the mold.
Hence, an improved electrical card connector is needed to overcome the above-mentioned deficiencies of current electrical card connectors.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an electrical card connector for use in mobile communications, particularly an electrical card connector with better mechanical strength and a smaller profile, and which has an improved shield.
An electrical card connector in accordance with the present invention comprises a top lid and a contact module. The top lid shields the contact module and has a metal cover and a pair of elongated grip arms. The metal cover and the grip arms are insert-molded into an integral unit. Each grip arm is separately formed at opposite sides of the cover and includes a rail and a rib projecting from a side of the rail. A pivot is provided at one end of the rail and is perpendicular to the rail, and a wedge extends from an opposite end of the rail. Additionally, the rib has a top face lower than a top face of the rail and cooperates with the side of the rail to hold an electrical card. The contact module includes an insulative housing and a plurality of contacts. Furthermore, a pair of shaft lids extends from two rearward corners of the housing while a pair of lock portions extends from two forward corners of the housing. Each shaft lid has a pivot hole for pivotably engaging with the pivots of the grip arms.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
