Abstract
An injector/extractor for circuit boards is disclosed. The device includes a slideably engagable locking member adapted to engage a locking pin mounted on a circuit board to prevent accidental release of a circuit board from a chassis.
Claims21
A locking circuit board extractor for releaseably mounting a circuit board in a chassis comprising:
- a) a body portion adapted to be mounted on an edge of the circuit board, the body portion having a lever arm, a means for engaging a pivot, and a means for engaging the chassis;
- b) a locking member mounted on said body portion and having an engagement arm, wherein said engagement arm is adapted to allow a locking point mounted on the circuit board to be releasably engaged by sliding the engagement arm in a direction substantially parallel to the edge of the circuit board.
A locking circuit board extractor for releaseably mounting a circuit board in a chassis comprising:
- a) a body portion having a lever arm, a means for engaging a pivot, and a means for engaging the chassis;
- and
- b) a locking member slideably mounted on the lever arm, the locking member having an engagement arm for releaseably engaging a locking point mounted on the circuit board.
A locking circuit board extractor for releaseably mounting a circuit board in a chassis comprising:
- a) a body portion having a lever arm, a means for engaging a pivot, and a means for engaging the chassis;
- and
- b) a locking member mounted on the lever arm, the locking member having an engagement arm for releaseably engaging a locking point mounted on the circuit board wherein the means for engaging the pivot comprises an elongated aperture constructed and arranged to allow the extractor to be slideably moved in a first direction to cause the engagement arm to engage the locking point, and in a second direction to cause the engagement arm to release the locking point.
A circuit board assembly having means for inserting and removing the circuit board from a chassis which comprises a circuit board having mounted thereon a locking circuit board extractor, a pivot, and a locking point, the extractor comprising:
- a) a body portion adapted to be mounted on an edge of the circuit board, the body portion having a lever arm, a means for engaging a pivot, and a means for engaging the chassis;
- and
- b) a locking member having an engagement arm, wherein said arm is adapted to allow a locking point mounted on the circuit board to be releasably engaged by sliding the arm in a direction substantially parallel to the edge of the circuit board.
A method for releasably locking a circuit board in a chassis which comprises the steps of:
- a) providing a circuit board in a chassis, the circuit board having mounted thereon a circuit board extractor, a pivot, and a locking point, the extractor comprising:
- i) a body portion adapted to be mounted on an edge of the circuit board, the body portion having a lever arm, a means for engaging a pivot, and a means for engaging the chassis;
- and
- ii) a locking member having an engagement arm, wherein said arm is adapted to allow a locking point mounted on the circuit board to be releasably engaged by sliding the arm in a direction substantially parallel to the edge of the circuit board;
- b) pivoting the body portion until the lever arm is substantially parallel with the edge of the circuit board;
- and
- c) sliding the looking member to cause the engagement arm to engage the locking point.
