Locking component, locking device and host securing an interface card

A locking device, comprising:

• two opposite retaining elements coupled to a rigid housing of a host, wherein each retaining element has a sliding slot having first and second slide portions in communication with each other, wherein each sliding slot is angled relative to a second direction between the first and second slide portions;
• and
• a locking element having two opposite pivot elements, each pivot element extending into one of the sliding slots such that the locking element is pivotable about the pivot element;
• wherein upon positioning the locking element so that the pivot element is positioned in the first slide portions of the retaining elements, the locking element is pivotable from an open position to an intermediate position, and wherein upon sliding the locking element along the second direction to move the pivot element from the first slide portions to the second slide portions, the locking element is movable from the intermediate position to a lock position to lock an interface card that has been inserted in the first direction into a card slot of the host, wherein the card slot extends along the second direction.

A host, comprising:

• a rigid housing;
• a circuit board securing within the rigid housing;
• a card slot in the circuit board, extending along a second direction, the card slot being for inserting an interface card in a first direction which is substantially perpendicular to the second direction;
• a locking device which comprises:
• two opposite retaining elements coupled to the rigid housing;
• a pivot element secured between the two opposite retaining elements;
• and
• a locking element including two opposite sliding slots, each sliding slot having first and second slide portions in communication with each other, wherein each sliding slot is angled relative to a second direction between the first and second slide portions, wherein the pivot element extends through the sliding slots;
• wherein upon disposing the pivot element in the first slide portions of the locking element, the locking element is pivotable about the pivot element from an open position to an intermediate position, and wherein upon sliding the locking element along the second direction to move the pivot element from the first slide portions to the second slide portions of the locking element, the locking element is movable from the intermediate position to a lock position to lock the interface card into the card slot.
