ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to an IC card connector apparatus, and particularly to an IC card connector apparatus which promotes an efficient use of space within a PC enclosure and which effectively eliminates cross talk between terminals thereof.
An IC card connector is commonly disposed in a notebook computer for connecting an IC card to a motherboard. Thus, a large amount of data is exchanged between the IC card and an electrical device mounted on the motherboard. Since the IC card can be movably received or ejected from the IC card connector, such a connector eases a restriction on dimensions of devices within a PC enclosure due to a limited space therein. The related prior art is disclosed in Taiwan Patent Application Nos. 83218076 and 84112508.
FIG. 1
shows a conventional stacked IC card connector
10
and two circuit board connectors
14
mounted on a motherboard
12
. Two transition boards
16
are received in the circuit board connectors
14
. Four arrays of terminals
18
extending from the stacked IC card connectors
10
are soldered to the two transition boards
16
. The stacked IC card connector
10
is electrically connected to the motherboard
12
via the two circuit board connectors
14
. However, the terminals
18
, boards
16
and circuit board connectors
14
occupy a significant amount of space, which may interfere with an efficient layout of components within the PC enclosure.
The connection of the transition boards
16
to the circuit board connectors
14
requires a high insertion force adversely affecting mechanical stability of the IC card connector
10
. In addition, the stacked structure is subject to a higher level of interference whereby false signals may be generated in signal transmission paths.
SUMMARY OF THE INVENTION
Accordingly, a primary purpose of the present invention is to provide an IC card connector apparatus which promotes an efficient use of space within a PC enclosure.
A second purpose of the invention is to provide an IC card connector apparatus benefiting low insertion force.
A third purpose of the invention is to provide an IC card connector apparatus which effectively eliminates cross talk between terminals thereof.
To fulfill the above-mentioned purposes, an IC card connector apparatus comprises a main body and a socket mounted on a motherboard. The main body includes two stacked insulative housings and a locator proximate the housings. Each housing has a mating face and defines a space for receiving an IC card therein. Two arrays of terminals in one set are disposed in each housing. Each terminal forms a mating portion which extends beyond the mating face and into the space for engaging the IC card. The four arrays of terminals are arranged in two arrays in the locator. Each terminal forms a mounting portion opposite and perpendicular to the mating portion. The mounting portions of the terminals are secured in outer opposite sides of the locator.
Moreover, two grounding plates are mounted on the housings and extend substantially parallel to the terminals. One of the grounding plates is bent to abut against the other grounding plate which is received between the two arrays of the mounting portions of the terminals in the locator. In assembly, the locator of the main body is inserted into the socket. The terminals and grounding plate of the main body electrically contact corresponding signal contacts and a grounding shell of the socket, respectively.
