1. Field of the Invention
This invention generally relates to an electrical card connector, and more particularly to one provided with simplified structure.
2. Description of the Prior Art
Conventional electrical card connector used in portable electronic devices for connecting an electrical card to a printed circuit board includes an insulative housing, a plurality of electrodes or contacts exposed in the housing for electrically connecting with circuit traces of the card and a holding device permitting the card to insert and remove therefrom.
U.S. Patent application publication No. 2005/0106921 A1 discloses such an electrical card connector for receiving mini SD card. The conventional electrical card connector includes an insulative housing and a plurality of conductive contacts. The insulative housing includes a pair of clamping arms which define a pair of retaining ribs for fastening the mini SD card. Since the conventional electrical card connector provides the retaining rib additionally to retain the mini SD card, thereby exceed the longitudinal length of the electrical card connector. In addition, it is not conventional to push the electrical card out of the electrical card connector.
Hence, an improved electrical card connector having a simplified structure is needed to solve the above problems.
It is an object of the present invention to provide a miniature electrical card connector.
In order to attain the objective above, an electrical card connector for receiving an electrical card includes an insulative housing defining a plurality of channels and a plurality of conductive contacts received in the channels. Each conductive contact projects beyond the insulative housing. The electrical card connector further includes a holding piece disposed in a rear portion of the insulative housing. The holding piece has a pair of V-shaped cantilevered beams for fastening the electrical card.

Each holding piece 30 includes a longitudinal base portion 31, a cutout 32 depressed from a middle portion of an upper edge of the base portion 31, a pair of V-shaped cantilevered beams 33 bent from opposite sides of the upper edge of the base portion 31.
The soldering portion 40 is substantially L-shaped metal sheet and provide barbs (not shown) at opposite edges of a vertical portion of the soldering portion 40.
Refer to
The holding piece 30 is inserted into the through slot 105 from down-to-up direction with the U-shaped cutout 32 engaging with the rib 107 of the channel 105. The pair of V-shaped cantilevered beams 30 is positioned below the protrusions 106 of the left and right side arms 101, 102. The vertical portions of the soldering portions 40 are received in the retaining grooves 113 of the insulative housing 10.
