ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a connector, and more particularly to a card edge connector including different kinds of conductive contacts.
U.S. Pat. Nos. 5,609,502 and 5,024,609 disclose two kinds of card edge connectors. Referring to
FIGS. 5
, and
6
, such connector
70
(
80
) includes a housing
71
(
81
) and a plurality of contacts
72
(
82
,
83
). The housing
71
(
81
) defines two rows of identical transverse cavities
73
,
74
(
84
,
85
) for receiving the corresponding contacts
72
(
82
,
83
) therein. The connectors
70
,
80
can't be properly attached to a circuit board
6
having a mating edge
60
and first contact pads
62
,
63
formed on one face and second contact pads
61
formed on an opposite face because the contacts
72
(
82
,
83
) are symmetrically received in the transverse cavities
73
,
74
(
84
,
85
). Thus, an improved card edge connector that can be attached to the circuit board
6
is provided by the present invention.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a card edge connector asymmetrically receiving different kinds of contacts in opposite sides of a housing thereof.
Another object of the present invention is to provide a card edge connector with several signal and power contacts thereby promoting proper electrical signal transfer though the connector.
Accordingly, a card edge connector in accordance with the present invention comprises an insulative housing and different kinds of conductive contacts. The housing includes a mating face and a mounting face. The housing defines an elongate slot in the mating face for receiving a mating edge of a circuit card having a plurality of conductive pads formed on opposite faces of the mating edge. The housing defines a plurality of transverse cavities aligned on each side thereof for receiving the conductive contacts therein. At least two kinds of different contacts are received in the transverse cavities of one side of the housing and a smaller number of different contacts are received in the cavities of an opposite side of the housing.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when taken in conjunction with the accompanying drawings.
