The socket defines a sliding groove. The engaging member includes a sliding piece engaged in the sliding groove. The sliding piece can slide along the slot to detach the engaging member from the socket. A chip may be mounted below the engaging member which member may be moved away from the socket to enable user to check the chip. ## Claims ### Claim 1 A socket device comprising: a socket mounted on a circuit board and defining a sliding groove; and an engaging member mounted to the socket and comprising a sliding piece engaged in the sliding groove; wherein the sliding piece is slidable along the sliding groove to detach the engaging member from the socket; wherein the socket comprises a clamping block which comprises an inclined guiding surface configured to guide the engaging member to be mounted to the socket. ### Claim 2 (depends on 1) The socket device of claim 1, wherein the sliding groove comprises an inner sidewall, a limiting slot is defined in the inner sidewall, and a limiting piece extending from the sliding piece is engaged in the limiting slot. ### Claim 3 (depends on 1) The socket device of claim 1, wherein the engaging member comprises a pressing portion, and the pressing portion is engaged with the clamping block to mount the engaging member to the socket. ### Claim 4 (depends on 3) The socket device of claim 3, wherein the socket further comprises a connecting portion and an engaging portion connected to the connecting portion, the sliding groove is defined in the engaging portion, the engaging portion comprises a mounting plate, and the sliding groove is located between the connecting portion and the mounting plate. ### Claim 5 (depends on 4) The socket device of claim 4, wherein the clamping block is located at a side of the mounting plate away from the sliding groove. ### Claim 6 (depends on 4) The socket device of claim 4, wherein the guiding surface extends slantedly to a top end of the mounting plate. ### Claim 7 (depends on 4) The socket device of claim 4, wherein the engaging member comprises the sliding piece, a base plate, and a connecting piece, and the sliding piece is connected to the base plate with the connecting piece; a receiving space is cooperatively defined by the sliding piece, the base plate, and the connecting piece; and the mounting plate is received in the receiving space. ### Claim 8 (depends on 7) The socket device of claim 7, wherein the pressing portion extends from the base plate, a notch is defined in the connecting piece, and the notch extends to the pressing portion. ### Claim 9 (depends on 1) The socket device of claim 1, wherein a thickness of the sliding piece is equal to a width of the sliding groove. ### Claim 10 A socket device comprising: a socket mounted on a circuit board and comprising a mounting plate, a clamping block extending from the mounting plate, and a sliding groove; and an engaging member movably mounted to the socket and comprising a pressing portion, a sliding piece slidably engaged in the sliding groove, a base plate, and a connecting piece, the connecting piece is perpendicularly connected to the base plate and the sliding piece, the pressing portion extends from the base plate, a receiving space is defined by the sliding piece, the base plate, and the connecting piece, and the mounting plate is configured to be received in the receiving space; wherein the pressing portion is engagable with the clamping block to fix the engaging member to the socket. ### Claim 11 (depends on 10) The socket device of claim 10, wherein the socket comprises a connecting portion and an engaging portion connected to the connecting portion, the engaging portion comprises the mounting plate and defines the sliding groove, and the sliding groove is located between the connecting portion and the mounting plate. ### Claim 12 (depends on 10) The socket device of claim 10, wherein the connecting piece defines a notch extending to the pressing portion. ### Claim 13 (depends on 10) The socket device of claim 10, wherein the sliding groove comprises an inner sidewall, a limiting slot is defined in the inner sidewall, and a limiting extending from the sliding piece is configured to be engaged in the limiting slot. ### Claim 14 A printed circuit board (PCB) assembly comprising: a circuit board comprising a chip; a socket mounted on the circuit board and defining a sliding groove; and an engaging member mounted to the socket and comprising a sliding piece engaged in the sliding groove; wherein the sliding piece is slidable along the slot to detach the engaging member from the socket and the chip is below the engaging member. ### Claim 15 (depends on 14) The PCB assembly of claim 14, wherein the socket further comprises a clamping block, and engaging member further comprises a pressing portion engaged with the clamping block.
