(12) Referring to FIGS. 1 and 8, an embodiment of the present disclosure includes an electrical socket 100, which is mated with an electrical plug 200 having three pins 201. Two of the three pins 201 are electrically connected with power cords. Each of the two of the three pins 201 includes a locking hole 202.

(13) Referring to FIGS. 1 and 2, the electrical socket 100 includes a housing 10 and at least two electrodes 20 disposed in the housing 10 and connected with a power cord 101. The electrical socket 100 further includes an elastic buckle 30 disposed in the housing 10 and a slider 50 provided and slidable in the housing 10.

(14) In this embodiment, the housing 10 has a cavity. The elastic buckle 30 and parts of the two electrodes 20 connected with the pins 201 are located in the cavity of the housing 10. The housing 10 can include a first cover plate 40 configured for covering the cavity. The slider 50 can be slidably disposed on the first cover plate 40 and partially protrudes into the cavity of the housing 10.

(15) Referring to FIGS. 3 and 6, four assembly holes 11 are defined in four corners of the housing 10. The first cover plate 40 includes four assembly pillars 41 matching with the four assembly holes 11 respectively. When the first cover plate 40 is assembled on the housing 10, the assembly pillars 41 will correspondingly insert into the assembly holes 11 of the housing 10, thereby realizing limit assembly between the first cover plate 40 and the housing 10.

(16) Referring to FIGS. 2 and 5, the housing 10 is further provided with three limiting pillars 12 separated from each other. The elastic buckle 30 includes two elastic pieces 31 and an ending part 310 connected with the two elastic pieces 31. The ending part 310 is disposed between the three limiting pillars 12, thereby realizing the elastic buckle 30 fixed relatively to the housing 10.

(17) The two electrodes 20 is configured for electrically connected with the power cord 101 such as a live cord, a zero cord. The electrical socket 100 can include another electrode which is connected with a ground cord.

(18) The two electrodes 20 connected with the live cord and the zero cord are disposed in one side of the housing 10 and are separated from outer sides of two elastic pieces 31 of the elastic buckle 30. The first cover plate 40 covers the housing 10. Another electrode connected to the ground cord is disposed on the other side of the housing 10 and is covered by the second cover plate 60. It can be understood that the electrical socket 100 is further wrapped with an insulating plastic 102 on the periphery of the housing 10, the second cover plate 60, and the first cover plate 40, in order to fix the housing 10, the second cover plate 60 and the first cover plate 40. And the insulating plastic 102 wraps connection position of the power cord 101 and the three electrodes 20.

(19) Referring to FIGS. 4 and 8, the two electrodes 20 for electrically connecting to the power cord 101 are respectively provided with through holes 21. Each of the two pins 201 of the electrical plug 200 are provided with a locking hole 202, which is matched with the through holes 21. When the pins 201 insert into the electrodes 20, the through holes 21 are placed coincidently with the locking holes 202. The through holes 21 and the locking holes 202 can have the same shape.

(20) Referring to FIG. 5, the two elastic pieces 31 of the elastic buckle 30 are disposed opposite to each other. Each of the two elastic pieces 31 is respectively provided with a first peg 32 corresponding to the through hole 21. When the slider 50 is mounted on the first cover plate 40, a part of the slider 50 extends into the housing 10 and between the two elastic pieces 31 of the elastic buckle 30. The elastic buckle 30 can be made of plastic. The first peg 32 and the two elastic pieces 31 can be an integral structure. The first peg 32 can be made of plastic and have a certain rigidity. The first peg 32 can be a rigid structure. When the slider 50 is pushed, the two elastic pieces 31 of the elastic buckle 30 will be driven to open and the first peg 32 will insert into the through hole 21 for limiting pins 201 which is inserted in the electrodes 20, thereby realizing the locking function of the electrical socket 100 to the electrical plug 200.

(21) When the first peg 32 inserts into the through hole 21 and the locking hole 202, the first peg 32 will abut to sidewall of the locking hole 202, in order to prevent the electrical plug 200 dropping out of the electrical socket 100.

(22) Referring to FIGS. 6 and 7, the slider 50 includes a pushing plate 51 disposed on the first cover plate 40 and a pushing pillar 52 vertically connected with the pushing plate 51. A slot 43 is defined on the first cover plate 40. An end of the pushing pillar 52 away from the first cover plate 40 extends through the slot 43 and into the housing 10 and is located between the two elastic pieces 31 of the elastic buckle 30. When the pushing plate 51 is pushed, part of the pushing pillar 52 slides along the slot 43 and the end of the pushing pillar 52 will move until the two elastic pieces 31 are open.

(23) Furthermore, a limiting portion 521 is disposed on each of opposite sides of the pushing pillar 52. Each of the two elastic pieces 31 is provided with a limiting mating portion 311. When pushing the slider 50, the pushing pillar 52 pushes the two elastic pieces 31 and the limiting portion 521 abuts the limiting mating portion 311 resulting in an increased distance between ends of the elastic pieces 31 and the first peg 32 inserts into the through hole 21. The limiting portion 521 and the limiting mating portion 311 can match to each other resulting in the limiting between the pushing pillar 52 and the two elastic pieces 31, in order to prevent the pushing pillar 52 from displacing under an elastic resilience force of the two elastic pieces 31.

(24) Referring to FIGS. 5 and 7, the limiting portion 521 can include a concave surface. The limiting mating portion 311 can include a convex surface cooperating with the concave surface of the limiting portion 521. It can be understood that the limiting portion 521 can include a convex surface and the limiting mating portion 311 can include a concave surface, or the limiting portion 521 can be a ridge structure and the limiting mating portion 311 can be a groove structure, according to needs.

(25) Referring to FIG. 7, a size of a part of the pushing pillar 52 closer to the ends of the elastic pieces 31 is larger than a size of the other part of the pushing pillar 52 away from the ends of the elastic pieces 31. It is easy to push the pushing pillar 52 and open the ends of the elastic pieces 31.

(26) Referring to FIGS. 5 and 7, each of the two elastic pieces 31 is further respectively provided with a second peg 33. The second peg 33 can be disposed on a surface of the elastic pieces 31 toward the first cover plate 40. The pushing pillar 52 is further provided with two bending plates 53. The two bending plates 53 are disposed on opposite sides of the pushing pillar 52. When returning the slider 50, the limiting portion 521 moves away from the limiting mating portion 311 and the two bending plates 53 abuts the second peg 33, resulting in driving the elastic pieces 31 to return, the first peg 32 to drop out of the through hole 21 and the pins 201 to be released easily.

(27) Each of the two bending plates 53 includes a cambered surface 531. The second peg 33 includes a mating surface 331 matching with the cambered surface 531. When the slider 50 is returned, the mating surface 331 of the second peg 33 abuts the cambered surface 531 of the two bending plates 53, resulting in the elastic pieces 31 returning.

(28) Referring to FIGS. 6 and 7, the pushing plate 51 is provided with a sliding limit element 511 on a surface facing the first cover plate 40. The first cover plate 40 is provided with a sliding mating element 42 matched with the sliding limit element to ensure the pushing plate 51 slidably couples with the first cover plate 40. The pushing plate 51 can be slidably pushed on the first cover plate 40 in both pushing the slider 50 and returning the slider 50. The engagement between the sliding limit element 511 and the sliding mating element 42 achieves a limit between the slider 50 and the first cover 40, thereby ensuring that the electrical socket 100 can be stably locked with the electrical plug 200.

(29) In this embodiment, the sliding limit element 511 includes four concave surfaces, and the sliding mating element 42 includes four protrusions. When pushing the pushing plate 51, two of the four concave surfaces will match with two of the four protrusions, result in limiting push between the pushing plate 51 and the first cover plate 40. When returning the pushing plate 51, other two of the four concave surfaces will match with the other two of the four protrusions, resulting in limiting return between the pushing plate 51 and the first cover plate 40. When the concave surfaces are pushed in the protrusions, a prompt sound can be emitted to indicate the electrical plug 200 is locked or unlocked by the electrical socket 100. It will be understood that the sliding mating element 42 can be a concave surface and the sliding limit element 511 can be a protrusion.

(30) The electrical socket 100 further includes a power light 70 disposed in the housing 10. The power light 70 is electrically connected with the electrodes 20. When the electrical socket 100 and the electrical plug 200 are electrically connected, the power light 70 can emit light, which serves as a reminder.

(31) Referring to FIG. 3, the housing 10 is provided with a mounting bracket 13 at a position between the two electrodes 20. The power light 70 is disposed on the mounting bracket 13 and electrically connected to the two electrodes 20.

(32) The electrical socket 100 of the present embodiment has following advantages. The pins 201 of the electrical plug 200 can insert into the electrical socket 100. When the electrical plug 200 needs to be locked, the slider 50 is pushed and the first peg 32 of the elastic buckle 30 will insert through the through holes 21 of electrodes and the locking holes 202 of the pins 201, so that the electrical plug 200 can be stably locked by the electrical socket 100. The operation thereof is simple and the electrical plug 200 cannot easily detach from the electrical socket 100.

(33) The technical features of the above-described embodiments may be combined in any combination. For the sake of brevity of description, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, all should be considered as within the scope of this disclosure.

(34) The above-described embodiments are merely illustrative of several embodiments of the present disclosure, and the description thereof is relatively specific and detailed, but is not to be construed as limiting the scope of the disclosure. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the disclosure. Therefore, the scope of the disclosure should be determined by the appended claims.
