Abstract
An electrical connector for testing an electronic package, includes an insulative housing, an insulative sliding plate mounted upon the housing and moveable horizontally along a transverse direction, and a cover up-and-down movable relative to the housing in a vertical direction. The cover forms the actuating parts to contact the rollers of the sliding plate when the cover is downwardly pressed so as to not only urge the sliding plate to move horizontally in the transverse direction but also smoothly move downwardly to a lower position where the electronic package may be loaded upon the sliding plate in a zero insertion force condition with regard to the contacts.
Claims20
An electrical connector comprising:
- an insulative housing defining a receiving cavity for receiving an electronic package therein;
- a plurality of contacts retained in the housing;
- an insulative sliding plate mounted upon the housing and back and forth moveable relative to the housing in a transverse direction;
- and
- a cover mounted upon the housing and up and down moveable relative to the housing in a vertical direction perpendicular to the transverse direction, said cover further including an actuating arm to sideward pushing the sliding plate in the transverse direction;
- wherein
- at least a roller is installed upon the sliding plate, and directly contacts the actuating arm so as not only rotate but also sidewardly move in the transverse direction in response to downward movement of the actuating arm in the vertical direction;
- wherein
- the cover forms at least one notch in a downward edge to compliantly receive an upper portion of said at least one roller when the cover is downwardly moved to a lower position in the vertical direction.
An electrical connector comprising:
- an insulative housing defining a receiving cavity for receiving an electronic package therein;
- a plurality of contacts retained in the housing;
- an insulative sliding plate mounted upon the housing and back and forth moveable relative to the housing in a transverse direction;
- and
- a cover mounted upon the housing and up and down moveable relative to the housing in a vertical direction perpendicular to the transverse direction, said cover including an actuating arm to sidewardly pushing the sliding plate in the transverse direction;
- wherein
- at least a roller is installed upon one of the housing and the actuating arm of the cover, so as to result in a dynamic friction between the cover and the sliding plate to drive the sliding plate to move in the transverse direction in response to downward movement of the actuating arm in the vertical direction, wherein
- said at least one roller is moveable in the vertical direction when installed on the cover, and immovable in both the vertical direction and the transverse direction when installed on the housing for stabilization consideration.
The electrical connector as claimed 12, wherein the cover is rectangular with a pair of long sides and a pair of short sides, and the roller is located around the long side.
An electrical connector comprising:
- an insulative housing defining a receiving cavity for receiving an electronic package therein;
- a plurality of contacts retained in the housing;
- an insulative sliding plate mounted upon the housing and back and forth moveable relative to the housing in a transverse direction, said sliding plate being rectangular with two long sides and two short sides;
- and
- a cover mounted upon the housing and up and down moveable relative to the housing in a vertical direction perpendicular to the transverse direction, said cover sidewardly pushing the sliding plate in the transverse direction;
- wherein
- a pair of rollers are positioned around two long sides of the sliding plate so as to result in dynamic friction between the cover and the sliding plate in response to downward movement of the actuating arm in the vertical direction;
- wherein
- the cover forms a pair of notches in opposite downward edges to respectively compliantly receive corresponding upper portions of the pair of rollers when the cover is downwardly moved to a lower position in the vertical direction.
