[0042] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0043] An embodiment of the present application provides a socket. Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of a socket provided by an embodiment of the present application, Figure 2 which is an exploded structural diagram of a socket body and a power cord assembly provided by an embodiment of the present application. The socket 000 may include: a housing 100, a socket body 200, and a power cord assembly 300.

[0044] The housing 100 in the socket 000 may have a receiving cavity A and a first opening K1 communicating with the receiving cavity A.

[0045] The socket body 200 in the socket 000 may be fixed in the receiving cavity A, and the socket body 200 may have a first hanging member 201. Here, the socket body 200 in the socket 000 may include: a first bracket 200a and a second bracket 200b connected to each other, and a conductive blade group (not shown in the figure) located between the first bracket 200a and the second bracket 200b. Among them, the first bracket 200a and the second bracket 200b may be used to carry the conductive blade group so that the conductive blade group can be fixed between the first bracket 200a and the second bracket 200b. Here, the first hanging member 201 of the socket body 200 may be fixed on the first bracket 200a.

[0046] It should be noted that the conductive blade group in the socket body 200 may be electrically connected to the power cord assembly 300, and the power cord assembly 300 may be electrically connected to an external power supply so that the power cord assembly 300 can be used to supply power to the socket 000. Among them, when the pins of the external plug of an external electrical device are inserted into the conductive blade group in the socket body 200, the circuit between the socket 000 and the external electrical device can be conducted through the conductive blade group, so that the socket 000 can supply power to the external electrical device.

[0047] The power cord assembly 300 in the socket 000 may include: a power cord body 301 and a connecting sleeve 302. The connecting sleeve 302 may be sleeved on the power cord body 301. Among them, a part of the power cord body 301 may be located inside the receiving cavity A, another part of the power cord body 301 can extend out of the receiving cavity A through the first opening K1 in the housing 100, and the connecting sleeve 302 may be located inside the receiving cavity A. Here, the part of the power cord body 301 that extends out of the receiving cavity A through the first opening K1 in the housing 100 can be used to connect to an external power supply, so that the power cord assembly 300 can be used to supply power to the socket 000.

[0048] Among them, the connecting sleeve 302 in the power cord assembly 300 can be snap-connected to the first hanging member 201 in the socket body 200. In this way, through the cooperation of the connecting sleeve 302 in the power cord assembly 300 and the first hanging member 201 in the socket body 200, the power cord assembly 300 and the socket body 200 can be stably connected together.

[0049] It should be noted that in the related art, the power cord and the socket body are usually fixed by means of threaded screws, and the bracket in the socket body usually needs to be provided with a threaded hole specifically for cooperating with the screw. However, since the bracket in the socket body is usually an injection-molded part, during the process of opening the threaded hole in the bracket of the socket body, the bracket in the socket body is extremely vulnerable to stress in the area where the threaded hole is opened, resulting in cracking of the bracket in the socket body, so that the reliability of the socket equipped with such a socket body is relatively low.

[0050] In the embodiment of the present application, since the socket body 200 can have a first hanging member 201, and the connecting sleeve 302 in the power cord assembly 300 can be snap-connected to the first hanging member 201, through the cooperation of the first hanging member 201 in the socket body 200 and the connecting sleeve 302 in the power cord assembly 300, the power cord assembly 300 and the socket body 200 can be stably connected together. In this way, there is no need to separately provide a threaded hole for cooperating with the screw inside the socket body 200, so that the socket body 200 can be ensured not to crack, and thus the reliability of the socket 000 can be improved.

[0051] In summary, a socket provided by an embodiment of the present application includes: a housing, a socket body, and a power cord assembly. Since the socket body may have a first hanging member, and the connecting sleeve in the power cord assembly can be snapped with the first hanging member, therefore, through the cooperation between the first hanging member in the socket body and the connecting sleeve in the power cord assembly, the power cord assembly and the socket body can be stably connected together. In this case, there is no need to separately provide a threaded hole for cooperating with a screw in the socket body, thereby ensuring that the socket body is not prone to cracking, and further improving the reliability of the socket.

[0052] In the embodiment of the present application, please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a connecting sleeve provided by an embodiment of the present application. The connecting sleeve 302 in the power cord assembly 300 may have a clamping cavity 302a and a second opening K2 communicating with the clamping cavity 302a. Among them, at least part of the first hanging member 201 in the socket body 200 can extend into the clamping cavity 302a through the second opening K2 to be snapped with the connecting sleeve 302 in the power cord assembly 300. In this way, the socket body 200 can be snapped with the connecting sleeve 302 in the power cord assembly 300 through the part extending into the clamping cavity 302a to ensure that the socket body 200 and the power cord assembly 300 are stably connected together.

[0053] In the present application, please refer to Figure 3 and Figure 4 , Figure 4 which is a schematic partial structural diagram of a socket body provided by an embodiment of the present application. The side surface of the first hanging member 201 in the socket body 200 may have a first clamping portion 201a, and the inner wall of the clamping cavity 302a in the connecting sleeve 302 may have a second clamping portion 3021 that is clamped with the first clamping portion 201a in the first hanging member 201. Exemplarily, the second clamping portion 3021 clamped with the first clamping portion 201a may be two mutually cooperating clips.

[0054] In this way, through the clamping cooperation between the first clamping portion 201a in the first hanging member 201 and the second clamping portion 3021 in the connecting sleeve 302, it can be ensured that the first hanging member 201 and the connecting sleeve 302 are more stably connected together.

[0055] In the embodiment of the present application, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of a power cord assembly provided by an embodiment of the present application. The part of the power cord body 301 in the power cord assembly 300 located in the accommodation cavity A may have: a first annular protrusion 301a and a second annular protrusion 301b. Here, the first annular protrusion 301a and the second annular protrusion 301b may be arranged in sequence in the axial direction of the power cord body 301.

[0056] Among them, the first annular protrusion 301a in the power cord body 301 can be located within the clamping cavity 302a, and the second annular protrusion 301b can be located outside the clamping cavity 302a in the connecting sleeve 302. In this case, it can be ensured that the power cord body 301 can be stably sleeved with the connecting sleeve 302.

[0057] In this application, please refer to Figure 6 , Figure 6 is a schematic structural diagram of another connecting sleeve provided by an embodiment of this application. The connecting sleeve 302 in the power cord assembly 300 may further have: a first through hole V1 and a second through hole V2 that communicate with the clamping cavity 302a in the connecting sleeve 302. Here, the first through hole V1 and the second through hole V2 are arranged in sequence in the axial direction of the power cord body 301.

[0058] Among them, the connecting sleeve 302 in the power cord assembly 300 can be sleeved between the first annular protrusion 301a and the second annular protrusion 301b through the first through hole V1, and the connecting sleeve 302 can also be sleeved on the side of the first annular protrusion 301a facing away from the second annular protrusion 301b through the second through hole V2. In this way, through the cooperative action of the first through hole V1 and the second through hole V2 in the connecting sleeve 302, it can be ensured that the power cord body 301 can be more stably sleeved with the connecting sleeve 302.

[0059] In the embodiment of this application, please refer to Figure 6 and Figure 7 , Figure 7 is a schematic structural diagram of a power cord body provided by an embodiment of this application. The part of the power cord body 301 in the power cord assembly 300 located within the accommodation cavity A may further have: a limiting protrusion 301c. Among them, the limiting protrusion 301c in the power cord body 301 can be located between the first annular protrusion 301a and the second annular protrusion 301b.

[0060] Here, the side wall of the first through hole V1 in the connecting sleeve 302 may have a limiting groove V11 that cooperates with the limiting protrusion 301c in the power cord body 301.

[0061] Among them, after the power cord body 301 and the connecting sleeve 302 in the power cord assembly 300 are sleeved together, at least part of the limiting protrusion 301c in the power cord body 301 can be located within the limiting groove V11 in the connecting sleeve 302.

[0062] In this case, after the power cord body 301 in the power cord assembly 300 is sleeved with the connection sleeve 302, through the cooperation between the limit protrusion 301c in the power cord body 301 and the limit groove V11 in the connection sleeve 302, it can be ensured that there is no relative rotation between the power cord body 301 and the connection sleeve 302 in the power cord assembly 300, so that it can be ensured that the power cord body 301 can be stably sleeved with the connection sleeve 302.

[0063] In this application, please refer to Figure 4 , one side of the first hanging part 201 in the socket body 200 facing the connection sleeve 302 in the power cord assembly 300 can be an arc-shaped concave surface S, and the arc-shaped concave surface S can be in contact with the outer side surface of the first annular protrusion 301a in the power cord body 301. In this case, after the power cord body 301 in the power cord assembly 300 is sleeved with the connection sleeve 302 and the connection sleeve 302 is clamped with the first hanging part 201 in the socket body 200, it can be ensured that the first hanging part 201 in the socket body 200 can better limit the power cord body 301 in the power cord assembly 300.

[0064] In the embodiment of this application, please refer to Figure 8 , Figure 8 is an exploded structural schematic diagram of a power cord assembly provided by an embodiment of this application. The connection sleeve 302 in the power cord assembly 300 can include: a first sub-connection sleeve 302b and a second sub-connection sleeve 302c. Among them, the first sub-connection sleeve 302b and the second sub-connection sleeve 302c in the connection sleeve 302 can be arranged in sequence in the radial direction of the power cord body 301 in the power cord assembly 300, and the first sub-connection sleeve 302b and the second sub-connection sleeve 302c can be detachably connected. In this way, it is convenient for the power cord body 301 to be sleeved with the connection sleeve 302.

[0065] Here, as Figure 8 shown, the first sub-connection sleeve 302b in the connection sleeve 302 can have a fourth clamping part 3022, and the fourth clamping part 3022 can be fixedly connected to the side surface of the first sub-connection sleeve 302b. The second sub-connection sleeve 302c in the connection sleeve 302 can have a fifth clamping part 3023 that cooperates with the fourth clamping part 3022.

[0066] Among them, after the first sub-connecting sleeve 302b and the second sub-connecting sleeve 302c in the connecting sleeve 302 are connected together, the fourth engaging portion 3022 in the first sub-connecting sleeve 302b can be engaged with the fifth engaging portion 3023 in the second sub-connecting sleeve 302c. In this way, through the cooperation of the fourth engaging portion 3022 in the first sub-connecting sleeve 302b and the fifth engaging portion 3023 in the second sub-connecting sleeve 302c, the first sub-connecting sleeve 302b and the second sub-connecting sleeve 302c can be stably connected together.

[0067] In this application, please refer to Figure 9 and Figure 10 , Figure 9 which is a schematic structural diagram of another socket provided by an embodiment of this application, Figure 10 and which is a partial structural diagram of another socket body provided by an embodiment of this application.

A part of the switch assembly 400 may be located in the through groove U and connected to the second hanging member 202 in the socket body 200, and another part of the switch assembly 400 can extend out of the receiving cavity A through the third opening K3 in the housing 100. In this case, through the cooperation of the switch assembly 400 and the second hanging member 202 in the socket body 200, the switch assembly 400 and the socket body 200 can be stably connected together. In this way, there is no need to fix the switch assembly 400 and the socket body 200 by means of threaded screws. Therefore, there is no need to separately provide a threaded hole in the socket body 200 for cooperating with the screw, so that the socket body 200 can be further ensured not to crack easily, and thus the reliability of the socket 000 can be improved.

[0069] It should be noted that by controlling the part of the switch assembly 400 that extends out of the receiving cavity A through the third opening K3 in the housing 100, the on-off of the circuit between the socket 000 and the external power supply can be controlled. Exemplarily, by touching the part of the switch assembly 400 that extends out of the receiving cavity A through the third opening K3 in the housing 100, the circuit between the socket 000 and the external power supply can be made to be connected, or by touching the part of the switch assembly 400 that extends out of the receiving cavity A through the third opening K3 in the housing 100, the circuit between the socket 000 and the external power supply can be made to be disconnected.

[0070] It should also be noted that as Figure 10As shown, the side surface of the second hanging member 202 may have a plurality of ribs 2021. Among them, after a part of the switch assembly 400 is located in the through groove U of the second hanging member 202, through the plurality of ribs 2021 in the second hanging member 202, it can be ensured that the part of the switch assembly 400 located in the through groove U is firmly connected to the second hanging member 202.

[0071] In the embodiment of the present application, please refer to Figure 11 , Figure 11 FIG. is an exploded schematic view of the cooperation between a switch assembly and a socket body provided in the embodiment of the present application. The side wall surface of the switch assembly 400 in the socket 000 may have a third annular protrusion 401 and a third engaging portion 402. Exemplarily, the third engaging portion 402 may be a buckle with an inclined surface.

[0072] Among them, the third annular protrusion 401 in the switch assembly 400 may abut against the side of the second hanging member 202 in the socket body 200 facing the third opening K3 in the housing 100, and the third engaging portion 402 in the switch assembly 400 can pass through the through groove U and then be engaged with the side of the second hanging member 202 in the socket body 200 facing away from the third opening K3 in the housing 100.

[0073] Here, the number of the third engaging portions 402 may be multiple. The side surface of the second hanging member 202 in the socket body 200 may also have a plurality of sliding grooves U1. Among them, the plurality of third engaging portions 402 may correspond to the plurality of sliding grooves U1 one by one.

[0074] Each third engaging portion 402 in the switch assembly 400 can pass through the through groove U through the corresponding sliding groove U1 to be engaged with the side of the second hanging member 202 facing away from the third opening K3 in the housing 100.

[0075] In this case, by the third annular protrusion 401 in the switch assembly 400 abutting against the side of the second hanging member 202 in the socket body 200 facing the third opening K3 in the housing 100, it can be ensured that the switch assembly 400 can be stably connected to the second hanging member 202 in the socket body 200. In addition, by the third engaging portion 402 in the switch assembly 400 passing through the through groove U and then being engaged with the side of the second hanging member 202 in the socket body 200 facing away from the third opening K3 in the housing 100, it can further ensure that the switch assembly 400 is more stably connected to the second hanging member 202 in the socket body 200.

[0076] In summary, a socket provided by an embodiment of the present application includes: a housing, a socket body, and a power cord assembly. Since the socket body can have a first hanging member, and the connecting sleeve in the power cord assembly can be snap-fitted with the first hanging member, therefore, through the cooperation between the first hanging member in the socket body and the connecting sleeve in the power cord assembly, the power cord assembly and the socket body can be stably connected together. In this case, there is no need to separately provide a threaded hole for cooperating with a screw in the socket body, thereby ensuring that the socket body is not prone to the bad phenomenon of cracking, and further improving the reliability of the socket.
