Claim of US Patent No. 11,032,932

1. A mount assembly, configured to be cooperative with an expansion card and a socket of a circuit board, the mount assembly comprising:a first slide rail and a second slide rail, configured to be fixed to the circuit board, wherein the first slide rail and the second slide rail each comprise a base part, a sidewall part, and a groove, the base part and the side wall part together form the groove therebetween, the expansion card is slidable in the grooves of the first slide rail and the second slide rail and is configured to be connected to the socket of the circuit board;
a first latch, comprising a first cantilever and a first protrusion, wherein the first cantilever comprises a first fixed end part and a first free end part that are located opposite to each other, the first fixed end part is fixed to the sidewall part of the first slide rail, the first protrusion protrudes from the first free end part and is located in the groove of the first slide rail, the first protrusion is configured to be engaged with an engagement hole of the expansion card; and
a first slidable stopper, comprising a stopper body and a handle portion, wherein the stopper body is slidably disposed on the sidewall part of the first slide rail and movable between a blocking position and a releasing position, and the handle portion protrudes from a side of the stopper body;
wherein, when the first slidable stopper is in the blocking position and the expansion card is inserted into the socket of the circuit board, the first slidable stopper blocks a side of the first free end part located away from the base part of the first slide rail and the first protrusion so as to prevent the first protrusion from disengaging from the engagement hole of the expansion card;
when the first slidable stopper is in the releasing position and the expansion card is inserted into the socket of the circuit board, the first slidable stopper is located away from the first free end part to allow the first protrusion to disengage from the engagement hole of the expansion card;
wherein the sidewall part of the first slide rail comprises a first wall portion, a second wall portion and a third wall portion, the first wall portion is connected to the third wall portion via the second wall portion, the second wall portion is located between the first wall portion and the third wall portion, the first fixed end part is fixed to the third wall portion, and the first slidable stopper is slidably disposed on the second wall portion.
