ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an electrical connector for providing an interconnection between electronic card and a printed circuit board, and particularly to an electrical connector having an ejector mechanism.
BACKGROUND OF THE INVENTION
Conventional electrical connectors generally have ejector mechanisms utilizing the operating principle of a lever. Such a conventional connector is, for example, disclosed in U.S. Pat. No. Re. 35938. Referring to
FIG. 8
, an electrical connector has a housing
12
for receiving an electronic card
2
therein and an ejector mechanism
10
. The ejector mechanism
10
includes a one-piece eject lever
14
and a one-piece actuator
16
. The eject lever
14
is transversely and pivotally mounted in the housing
12
for ejecting the card
2
out of the housing
12
. A pair of pivot bosses
48
projects from a rear wall of the connector to engage a pair of pivot recess
46
defined on two sides of the eject lever
14
, whereby the eject lever
14
can pivot in the direction of double-headed arrow “E”. The actuator
16
is longitudinally and movably mounted within an integrally molded channel
34
in the housing
12
and is engageable with the eject lever
14
for manual actuation thereof
The arrangement of the pivot bosses
48
and the transverse eject lever
14
occupies much space within the connector, resulting in the connector having a relatively large size. This design goes against the trend in electronic devices toward miniaturization. Furthermore, the ejector mechanism
10
requires precise cooperation between the actuator
16
and the channel
34
and therefore requires high manufacture precision, thereby making the manufacture more complicated.
This invention is directed to solving the above problems and satisfying the need for a very simple and easily operated ejecting system.
BRIEF SUMMARY OF THE INVENTION
A main object, therefore, of the present invention is to provide an improved ejector system for ejecting an electronic card easily.
Another object is to provide a simple ejector mechanism, which occupies a small space and simplifies the manufacture of the electrical connector used with it.
An electrical connector in accordance with the present invention comprises an insulative housing, a plurality of electrical contacts received in the insulative housing and an ejector mechanism mounted in one side of the insulative housing. The ejector mechanism includes a push-rod movably received in the housing, a spring element, a push block movably mounted in the housing adjacent to the push-rod and an actuator movably mounted in the housing between the push-rod and push block. The spring element is received in the housing for providing a pushing force on the card received in the housing. When the card is inserted into the connector, the push-rod is pushed by the card to move forwardly and compresses the spring element, and the actuator abuts against the push-rod; when an external force is exerted on the push block, the actuator is pushed by the push block and disengages from the push-rod, and the spring element is released to drive the push-rod to eject the card.
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.
