The main body includes a connection seat, a receiving recess and a latching slot. The connection seat is disposed within the receiving recess and configured to electrically connect with a plug passing, when the power plug is fitted in the receiving recess along a first direction. The latching slot is in communication with the receiving recess. The latch member includes an arm slidable along the latching slot from a first position to a second position along a second direction. The arm includes at least one protrusion configured to slide into the receiving recess for engaging with a lateral wall of the power plug when the arm slides towards the second position. ## Claims ###

the connection seat is disposed within the receiving recess and configured to electrically connect with a power plug when the power plug is fitted in the receiving recess along a first direction; and at least one latch member comprising at least one arm slidable along the latching slot from a first position to a second position along a second direction, wherein the arm comprises at least one protrusion configured to slide into the receiving recess for engaging with a lateral wall of the power plug when the arm slides towards the second position. ### Claim 2 (depends on 1) The power socket according to claim 1, wherein when the arm moves towards the first position, the at least one protrusion of the arm is configured to move away from the receiving recess. ### Claim 3 (depends on 1) The power socket according to claim 1, wherein the at least one latching slot extends along the second direction inwardly from a first outer wall of the main body. ### Claim 4 (depends on 1) The power socket according to claim 1, wherein the at least one protrusion protrudes laterally from a side of the arm such that the protrusion protrudes toward the receiving recess when the arm is in the second position. ### Claim 5 (depends on 1) The power socket according to claim 1, wherein the at least one latching slot comprises a first latching slot and a second latching slot disposed on two opposite sides of the receiving recess of the main body, respectively, wherein the first latching slot and the second latching slot extends along the second direction inwardly from a first outer wall of the main body, wherein the at least one arm of the latch member comprises a first arm slidable along the first latching slot and a second arm slidable along the second latching slot, wherein the first arm comprises a first protrusion and a second protrusion, each protruding laterally from a side of the first arm such that the first protrusion and the second protrusion protrudes toward the receiving recess when the first arm is in the second position, wherein the second arm comprises a third protrusion and a fourth protrusion, each protruding laterally from a side of the second arm such that the third protrusion and the fourth protrusion protrudes toward the receiving recess when the second arm is in the second position, wherein when the power plug is fitted in the receiving recess along the first direction for electrically connecting with the connection seat, and the first arm and the second arm are operated to slide from the first position towards the second position along the second direction, the first protrusion and the second protrusion are caused to slide into the receiving recess and abut against a first lateral wall of the power plug, and the third protrusion and the fourth protrusion are caused to slide into the receiving recess and abut against a second lateral wall of the power plug. ### Claim 6 (depends on 5) The power socket according to claim 5, wherein the power plug comprises four lateral walls, the first lateral wall and the second lateral wall being located on opposite sides of the power plug, and a third lateral wall and a fourth lateral wall being located on opposite sides of the power plug, and wherein each one of the first lateral wall and the second lateral wall is wider than each one of the third lateral wall and the fourth lateral wall of the power plug. ### Claim 7 (depends on 6) The power socket according to claim 6, wherein the length of the first lateral wall is shorter than the length of the second lateral wall, and the distance between the first protrusion and the second protrusion is shorter than the distance between the third protrusion and the fourth protrusion. ### Claim 8 (depends on 7) The power socket according to claim 7, wherein the protrusions are arranged in the shape of a trapezoid such that each protrusion is located at one corner of the trapezoid. ### Claim 9 (depends on 5) The power socket according to claim 5, wherein when the first arm and the second arm move toward the first position, the first protrusion and the second protrusion of the first arm and the third protrusion and the fourth protrusion of the second arm are effected to move away from the receiving recess. ### Claim 10 (depends on 5) The power socket according to claim 5, wherein when the first arm and the second arm move toward the first position, the first protrusion and the second protrusion of the first arm are effected to move away from the first latching slot, and the third protrusion and the fourth protrusion of the second arm are effected to move away from the second latching slot. ### Claim 11 (depends on 5) The power socket according to claim 5, wherein the latch member comprises a connection part disposed between the first arm and the second arm, wherein when the first arm and the second arm are at the first position, the connection part is configured to engage with the first outer wall of the main body. ### Claim 12 (depends on 11) The power socket according to claim 11, wherein the latch member comprises a holding part disposed between the first arm and the second arm, wherein the holding part is operable to slide the first arm and the second arm along the first latching slot and the second latching slot, respectively. ### Claim 13 (depends on 12) The power socket according to claim 12, wherein the holding part comprises an opening for insertion of a finger to operate a movement of the first arm and the second arm. ### Claim 14 (depends on 1) The power socket according to claim 1, wherein the latch member comprises metal material. ### Claim 15 (depends on 1) The power socket according to claim 1, wherein the latch member comprises a holding part connected to one end of the at least one arm, and wherein the holding part is configured to be held by a user to control the at least one arm to slide along the at least one latching slot. ### Claim 16 (depends on 15) The power socket according to claim 15, wherein the holding part comprises an opening for allowing insertion of a finger of the user to control the at least one arm to slide along the at least one latching slot. ### Claim 17 (depends on 15) The power socket according to claim 15, wherein the latch member comprises a stop part disposed at an end opposite to the holding part, and wherein when the at least one arm is moved from the second position towards the first position, the stop part is configured to obstruct the latch member from being detached from the main body. ### Claim 18 (depends on 17) The power socket according to claim 17, wherein the at least one latching slot extends along the second direction inwardly from a first outer wall of the main body towards a second outer wall of the main body, and wherein the first outer wall and the second outer wall are opposite to each other, and the holding part and the stop part are adjacent to the first outer wall and the second outer wall of the main body, respectively. ### Claim 19 (depends on 17) The power socket according to claim 17, wherein the stop part comprises a barb, a hook, or a protruded stopper. ### Claim 20 (depends on 15)
