[0002] A socket is a seat that can be plugged with one or more circuit wires. Various wires can be plugged into it to facilitate connection with other circuits. A power socket is an electrical device that provides a power interface for household appliances. It is also an electrical accessory that is used more frequently in residential electrical design. It is closely related to people's lives.

[0003] Children with low safety awareness may insert nails, copper wires or other conductive objects into the sockets out of curiosity, or insert their hands into the sockets, which can easily lead to electric shock accidents. As sockets are now everywhere, it is difficult to keep them out of children's reach, so the only way to prevent electric shock accidents is to improve the anti-electric shock performance of the sockets.

[0004] In addition, in daily life, sockets are also used in places with a lot of moisture, such as kitchens and bathrooms. Because there is plenty of moisture in these places, moisture will accumulate inside the sockets.

[0062] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0063] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0064] This embodiment relates to an internal structure of a socket, that is, a socket liner, referring to Figure 1-Figure 2 , comprising: an insulating liner bottom shell 100, an insulating liner upper cover 200 covering the insulating liner bottom shell 100, and two conductive contact pieces 300 accommodated in the insulating liner bottom shell 100 and partially extending to the front side of the insulating liner bottom shell 100. A socket hole 210 is provided on the upper end surface of the insulating liner upper cover 200. The portion of the conductive contact piece assembly 300 extending to the front side of the insulating liner bottom shell 100 is used to contact the conductive piece 400 of the socket.

[0065] Reference Figure 2-Figure 3 ,and Figure 10-13The conductive contact assembly 300 includes: a conductive elastic member and a contact sheet 330. The conductive elastic member includes: a clamping portion 311 located at the lower side of the socket hole 210 and used to contact the external plug electrode, and an elastic foot 322 extending from the clamping portion 311 to the front side; the elastic foot 322 partially extends to the lower side of the socket hole 210 and close to the front side of the socket hole 210. The contact sheet 330 is provided separately from the conductive elastic member, and is located in front of the elastic foot 322 of the conductive elastic member, and contacts the conductive sheet 400.

[0066] When the external plug electrode is inserted into the socket hole 210, the external plug electrode contacts the clamping portion 311 of the conductive elastic member, and at the same time, the external plug electrode squeezes the elastic foot 322 of the conductive elastic member. The elastic foot 322 is squeezed and moves forward, so that the end of the elastic foot 322 contacts the contact sheet 330, and then the external plug electrode, the conductive elastic member, the contact sheet 330 and the conductive sheet 400 are contacted and connected in sequence; when the external plug electrode is pulled out of the socket hole 210, the external plug electrode is no longer in contact with the clamping portion 311 of the conductive elastic member, and at the same time, the elastic foot 322 is no longer squeezed by the external plug electrode, and then the elastic foot 322 is reset.

[0067] By independently providing a conductive elastic member and a contact sheet 330, since the contact sheet 330 is disconnected from the conductive elastic member under normal circumstances, electric shock will not occur even if the user accidentally touches the conductive elastic member near the socket hole 210; and since the elastic foot 322 of the conductive elastic member partially extends to the lower side of the socket hole 210 and is close to the front side of the socket hole 210, when other objects are mistakenly inserted into the socket hole 210, the elastic foot 322 cannot be squeezed or it is difficult to completely squeeze the elastic foot 322, and the conductive elastic member will not contact and conduct with the contact sheet 330, thereby further reducing the risk of electric shock.

[0068] Specifically in this embodiment, refer to Figure 10-Figure 14 The conductive elastic member includes: a conductive contact 310 and a conductive spring 320. The conductive contact 310 includes: a clamping portion 311, and a first fixing portion 312 extending from the clamping portion 311 to the front side. The conductive spring 320 includes: a second fixing portion 321 fixedly connected to the first fixing portion 312 of the conductive contact 310, an elastic foot 322 extending from the second fixing portion 321 and having its end located at the front side, and a contact head 323 arranged at the end of the elastic foot 322.

[0069] The conductive contact piece 310 and the conductive spring piece 320 are independently provided and then fixed together instead of being integrally formed, which greatly reduces the complexity of the mold, reduces the mold opening cost, reduces the process difficulty, and saves materials.

[0070] In this embodiment, the material of the conductive spring 320 is phosphor copper, and the materials of the conductive contact 310 and the contact piece 330 are both brass. Phosphor copper has a better rebound effect than brass, and can still maintain good elasticity after 5,000 or even 10,000 tests, but the cost of using phosphor copper is much higher than that of using brass, so phosphor copper is only used in the conductive spring 320 that requires a better rebound effect. If the conductive contact 310 and the conductive spring 320 are all made of brass, although the price is low, after repeated use, there is a problem that the rebound elasticity of the conductive spring 320 is reduced, resulting in poor contact; if the conductive contact 310 and the conductive spring 320 are all made of phosphor copper, although the performance is superior, the cost is too high. This solution solves this problem by using phosphor copper in the key component-the conductive spring 320.

[0071] More specifically, the conductive spring 320 is made of C5191 phosphor copper.

[0072] Reference Figure 13-14 The elastic foot 322 includes: a base extension portion 3224 , a first extension portion 3221 , a second extension portion 3222 and a third extension portion 3223 .

[0073] The base extension portion 3224 extends from the second fixing portion 321 and forms a plurality of bends; the first extension portion 3221 extends obliquely upward from the end of the base extension portion 3224; the second extension portion 3222 extends from the end of the first extension portion 3221 and bends downward and extends; the third extension portion 3223 extends from the end of the second extension portion 3222 and extends downward and toward the front. The contact head 323 is disposed at the end of the third extension portion 3223. Such a structural design effectively improves the elasticity of the elastic foot 322.

[0074] Reference Fig.13The contact piece 330 includes: a base 331; an upper clip 332 extending from the base 331 to the rear side and located above the front side of the contact head 323 of the conductive spring piece 320; and a lower clip 333 extending from the base 331 to the rear side and located below the front side of the contact head 323 of the conductive spring piece 320. After being squeezed and moved, the elastic foot 322 enters between the upper clip 332 and the lower clip 333, stretching the upper clip 332 and the lower clip 333 apart, and achieving contact and conduction with the upper clip 332 and the lower clip 333. The contact piece 330 is configured to have an upper clamping piece 332 and a lower clamping piece 333, and the distance between the upper clamping piece 332 and the lower clamping piece 333 is smaller than the thickness of the contact head 323. With such a configuration, when the contact head 323 enters between the upper clamping piece 332 and the lower clamping piece 333 along the movement path, the upper clamping piece 332 and the lower clamping piece 333 will inevitably be stretched apart. After being stretched apart, the upper clamping piece 332 and the lower clamping piece 333 will be clamped on both sides of the contact head 323 under the action of the rebound force, thereby ensuring good contact between the contact piece 330 and the conductive elastic piece 320. In order to make the contact head 323 enter between the upper clamping piece 332 and the lower clamping piece 333 more smoothly, the upper clamping piece 332 and the lower clamping piece 333 have a first guide surface 334 open outward at one end close to the elastic foot 322.

[0075] Reference Figure 10-13 The clamping portion 311 of the conductive contact sheet 310 is in the form of a sheet and folded into a U shape, and the first fixing portion 312 is in the form of a sheet. The upper end of the clamping portion 311 has a second guide surface 3111 open to the outside. The second guide surface 3111 is used to make the external plug electrode enter the clamping portion 311 more smoothly.

[0076] Reference Figure 11-13 The first fixing portion 312 of the conductive contact piece 310 is provided with a first rivet hole 3121, and the second fixing portion 321 of the conductive spring piece 320 is provided with a corresponding second rivet hole 3211, and the second fixing portion 321 is fixed to the first fixing portion 312 by riveting. Specifically in this embodiment, the first fixing portion 312 of the conductive contact piece 310 is provided with two first rivet holes 3121, and the second fixing portion 321 of the conductive spring piece 320 is correspondingly provided with two second rivet holes 3211, and the riveted connection at two points is more stable.

[0077] Reference Figure 1-Figure 9 The insulating inner shell 100 has a cavity for accommodating the conductive contact assembly 300. A partition is provided in the insulating inner shell 100, and the partition separates the cavity into an independent first cavity a and a second cavity b. One socket hole 210 of the insulating inner shell upper cover 200 is located above the first cavity a, and the other socket hole 210 is located above the second cavity b. One conductive contact assembly 300 is accommodated in the first cavity a, and the other conductive contact assembly 300 is accommodated in the second cavity b.

[0078] If no plug is inserted into the socket hole 210, since the insulating inner liner upper cover 200 and the insulating inner liner bottom shell 100 are not electrically charged, splashing water will not cause a short circuit; when the power is on and water enters both socket holes 210, the water is divided into the first cavity a and the second cavity b, and the neutral wire and the live wire cannot form a loop, thereby eliminating the risk of short circuit or leakage.

[0079] As a preferred solution, refer to Figure 6-Figure 8 , the bottom surface of the first cavity a is provided with a plurality of first water leakage holes d, the bottom surface of the second cavity b is provided with a plurality of second water leakage holes e, the area of ​​the corresponding socket hole 210 above the first cavity a is smaller than the sum of the areas of the plurality of first water leakage holes d, and the area of ​​the corresponding socket hole 210 above the second cavity b is smaller than the sum of the areas of the plurality of second water leakage holes e. Of course, in some embodiments, only one first water leakage hole d and one second water leakage hole e may be provided, as long as the area of ​​the corresponding socket hole 210 above the first cavity a is smaller than the sum of the areas of the plurality of first water leakage holes d, and the area of ​​the corresponding socket hole 210 above the second cavity b is smaller than the sum of the areas of the plurality of second water leakage holes e.

[0080] The water splashed into the first cavity a and the second cavity b will be instantly discharged through the first leakage hole d and the second leakage hole e, thereby avoiding water accumulation and preventing the current from forming a circuit through the water. Avoiding water accumulation can also effectively protect the conductive contact 310. And because the area of ​​the corresponding socket hole 210 above the first cavity a is smaller than the sum of the areas of the first leakage holes d, and the area of ​​the corresponding socket hole 210 above the second cavity b is smaller than the sum of the areas of the second leakage holes e, the principle of small intake and large discharge is adopted, so that less water leaks in and a larger amount is discharged, and the splashed water is prevented from accumulating inside the first cavity a and the second cavity b.

[0081] Take the three-hole socket as an example, refer to Figure 1-Figure 9 The upper end surface of the insulating liner upper cover 200 is provided with three socket holes 210; there are three conductive sheets 400; there are three conductive contact assemblies 300, which are respectively the L conductive contact assembly accommodated in the first cavity a, the N conductive contact assembly accommodated in the second cavity b, and the ground conductive contact assembly. There are three partitions, namely the first partition 110, the second partition 120 and the third partition 130. The first partition 110, the second partition 120 and the third partition 130 separate the interior of the cavity into the first cavity a, the second cavity b and the third cavity c for accommodating the ground conductive contact assembly; a socket hole 210 of the insulating liner upper cover 200 is located above the third cavity c. The bottom surface of the third cavity c is provided with a plurality of third water leakage holes f, and the area of ​​the corresponding socket hole 210 above the third cavity c is less than the sum of the areas of the plurality of third water leakage holes f. Of course, in some embodiments, only one third water leakage hole f may be provided, and the area of ​​the corresponding socket hole 210 above the third cavity c is smaller than the area of ​​the third water leakage hole f.

[0082] Reference Figure 8 The lower side of the insulating liner bottom shell 100 is provided with a heightening rib 140 to raise the first leakage hole d, the second leakage hole e and the third leakage hole f. Therefore, even if water accumulates outside the insulating liner bottom shell 100, the neutral wire and the live wire cannot form a loop, thereby eliminating the risk of short circuit or leakage.

[0083] Reference Figure 3-Figure 6 The front end surface of the insulating liner bottom shell 100 is provided with a first crack g from the upper edge downwards, which is connected to the first cavity a and for the L conductive contact assembly to extend out. The front end surface of the insulating liner bottom shell 100 is provided with a second crack h from the upper edge downwards, which is connected to the second cavity b and for the N conductive contact assembly to extend out. Since the L conductive contact assembly and the N conductive contact assembly must extend out from the insulating liner bottom shell 100, if water splashes from the outside of the insulating bottom shell, it is not easy for water to enter therefrom because the first crack g and the second crack h have a certain height. Preferably, the lower edge of the first crack g and the second crack h is at least 0.5 cm away from the lowest side of the insulating liner bottom shell 100.

[0084] Reference Figure 6 , Figure 7 and Fig. 9 The third cavity c is provided with a support protrusion 150, and a protrusion 160 is provided on the support protrusion 150. The grounding conductive contact assembly 300 passes through the protrusion 160 and is placed on the support protrusion 150. The side walls of the first cavity a and the second cavity b are provided with a plurality of convex ridges protruding inward, and the plurality of convex ridges jointly define the positions of the L conductive contact assembly and the N conductive contact assembly. Thus, the grounding conductive contact assembly, the L conductive contact assembly, and the N conductive contact assembly are accommodated in the socket inner shell.

[0085] This solution also provides a socket, referring to Figure 15-16 , comprising: an insulating socket bottom shell 500, an insulating socket upper cover 600 covered on the insulating socket bottom shell 500, and at least one socket internal structure as described above and accommodated in the insulating socket bottom shell 500.

[0086] In addition to being waterproof and anti-electric shock, the socket can also save electricity and reduce carbon emissions.

[0087] Existing sockets will lose power when in standby mode, increasing carbon emissions. However, in a socket adopting the socket internal structure of the present solution, since the contact piece 330 is disconnected from the conductive elastic member under normal conditions, that is, when no plug is inserted into the socket adopting the present solution, it is in an open circuit state, and will not lose power, effectively reducing carbon emissions.

[0088] Reference Figure 15-16The inner bottom wall of the insulating socket bottom shell 500 is provided with a surrounding wall 510 with protrusions all around. The socket liner is assembled on the surrounding wall 510 through the insulating liner bottom shell 100. A plurality of socket water leakage holes 520 connected to the outside are opened between the surrounding walls 510. When water enters the socket hole 210 of the socket, the water flows into the socket liner, then flows out from the water leakage holes on the bottom side of the socket liner, and finally flows out from the socket water leakage holes 520 of the insulating socket bottom shell 500. Water will not accumulate in the socket. A padding block 530 is provided on the lower side of the insulating socket bottom shell 500, so that the water discharged from the socket water leakage holes 520 will not soak the socket.

[0089] The working principle of the utility model is as follows: since the contact piece 330 is disconnected from the conductive elastic part under normal conditions, even if the user accidentally touches the conductive elastic part near the socket hole 210, no electric shock will occur; and since the elastic foot 322 of the conductive elastic part partially extends to the lower side of the socket hole 210 and is close to the front side of the socket hole 210, when other objects are mistakenly inserted into the socket hole 210, the elastic foot 322 cannot be squeezed or it is difficult to completely squeeze the elastic foot 322, and the conductive elastic part will not contact and conduct with the contact piece 330, further reducing the risk of electric shock. In addition, if there is no plug inserted into the socket hole 210, since the insulating inner shell cover 200 and the insulating inner shell bottom shell 100 are not charged, the splashing of water will not cause a short circuit; when the power is on and water enters both socket holes 210, the water is divided into the first cavity a and the second cavity b, and the neutral line and the live line cannot form a loop, thereby eliminating the risk of short circuit or leakage. In addition to being waterproof and anti-electric shock, the socket can also save electricity and reduce carbon emissions.

[0090] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
