Leiterplattenverbinder mit verbessertem Verriegelungs- und Auswerfmechanismus

摘要

The connector comprises a connector housing having an elongated card slot disposed in it and extending between two opposing end portions of the connector. The card slot has a predetermined longitudinal axis and is adapted to receive the circuit card edge in it in an electrically operative relationship. The connector housing is defined by a pair of opposing sidewalls extending generally parallel to the axis and an endwall integral with and extending between the sidewalls. The endwall has a slot to define a pair of spaced apart, upstanding endwall sections. Each endwall section extends generally perpendicularly from an end portion of one of the sidewalls to define an L-shaped structure. A number of contact terminals are disposed in the housing. Each terminal has a portion positioned in the card slot for slidingly engaging the circuit card upon insertion of ir into the card slot. A latch/eject mechanism is positioned on at least one end portion of the connector housing, and includes a latch/eject member which is rotatable between a first position at which the circuit card is retained within the card slot and a second position at which at least a portion of the circuit card is ejected from the card slot and at which a portion of the latch/eject member extends through the slot in the endwall. The latch/eject mechanism includes a device for limiting the rotation of the latch/eject member during ejection of the circuit card from the card slot. The rotation limiting device includes an engagement surface formed on the latch/eject member. The engagement surface is generally vertical and engages one of the connector housing endwall sections when the latch/eject member is moved to the second position to thereby limit rotation of the latch/eject member. A device rotatably retains the latch/eject member within the housing.
