[0030] A power socket refers to a socket into which one or more circuit wiring can be inserted. By connecting and disconnecting the circuit between the line and the copper part, the on and off of this part of the circuit is finally achieved. With the progress of technology and the improvement of people's living standards, electrical equipment is more and more widely used in daily life. As a key component connecting electrical equipment and the power supply, the safety and reliability of the power socket are particularly important. In the related technology, the power socket is a box structure with a flat surface, and is provided with through holes for plugging and connecting. In a humid environment, this kind of power socket often has the problem of insufficient waterproof performance, and water is easy to enter the socket interior from the through holes, which is likely to induce problems such as short circuit, electric leakage, and even electric shock, and there are obvious potential safety hazards.

[0031] Most of the waterproof sockets on the market at present adopt simple measures such as sealing rubber rings and waterproof covers for waterproof treatment, but these methods often have defects such as poor waterproof effect, inconvenient operation, and affecting aesthetics. Especially when the socket is exposed to a humid environment for a long time or encounters sudden water flow impact, the traditional waterproof measures are difficult to effectively prevent moisture from penetrating into the socket interior, thus threatening the safety of electricity use. Therefore, developing a waterproof power socket with reasonable structure, excellent waterproof effect, convenient operation and not affecting aesthetics is of great significance for improving the safety of household and industrial electricity use.

[0032] The following refers to the attached Figure 1 to the attached Figure 5 , and describes the waterproof power socket of the embodiment of the present utility model, which has good waterproof performance, can significantly reduce risks such as short circuit and electric leakage, and has good safety performance.

[0033] Referring to Figures 1 to 5 , a waterproof power socket of an embodiment of the present utility model includes a bottom box 100, a face cover 200, and at least one plug-in conductive module 300. The face cover 200 is connected to the bottom box 100, and the plug-in conductive module 300 is installed in the bottom box 100. The plug-in conductive module 300 is specifically installed in the bottom box 100 through a positioning structure. On the side of the plug-in conductive module 300 close to the face cover 200, there are jacks 310 for plugging the plug of the power supply head.

[0034] The middle part of the cover 200 is bent and raised in a direction away from the bottom box 100 to form at least one waterproof cover part 210, that is, the top surface of the waterproof cover part 210 is located above the top surface of the cover 200, the number of the waterproof cover parts 210 corresponds to the number of the plug-in conductive modules 300 and the positions are matched accordingly, the thickness of the waterproof cover part 210 is uniformly equal to the thickness of the area of ​​the cover 200 except the waterproof cover part 210, that is, the waterproof cover part 210 is an integral structure of the cover 200, and the thickness of each area of ​​the cover 200 is uniformly equal. The curved panel is generally manufactured by injection molding to The cover 200 is formed with a curved convex waterproof cover portion 210. By setting the cover 200 and the waterproof cover portion 210 with uniform thickness, the depth of the power plug pin inserted into the socket 310 during plugging can be effectively controlled. While ensuring that the convexity is high enough to form a good waterproof performance, the plug-in connection structure between the power plug and the plug-in conductive module 300 can be effectively ensured to be stable and reliable. The universal plug-in conductive module 300 can be used to achieve an effective plug-in conductive connection. The shape and size of the waterproof cover portion 210 are respectively matched with the shape and size of the top of the plug-in conductive module 300. The waterproof cover 210 is covered on the top of each corresponding conductive plug module 300. The waterproof cover 210 not only forms a good waterproof protection effect for the conductive plug module 300, but also forms a good limiting effect for the conductive plug module 300, which can effectively improve the structural stability of the overall waterproof power socket. The waterproof cover 210 is provided with a first clearance hole 211 for making way for the socket 310. In the same set of waterproof cover 210 and conductive plug module 300, the center of each first clearance hole 211 is aligned with the center of each corresponding socket 310. , and the line connecting the two centers is perpendicular to the cover 200, the shape of the first clearance hole 211 at the corresponding position is the same as the shape of the plug hole 310, the opening area of ​​the first clearance hole 211 is larger than the opening area of ​​the plug hole 310, and the two opposite inner walls of the first clearance hole 211 are connected with an elastic protective sheet 212, and the opposite edges of the two elastic protective sheets 212 are in contact with each other, that is, in the same first clearance hole 211, the edge of one side of each elastic protective sheet 212 away from the inner wall to which it is connected is an opening and closing edge, and the opening and closing edges of the two elastic protective sheets 212 are in contact with each other to form a sealing protection effect. When idle, the two elastic protective sheets 212 are in contact with the edge away from the wall of the first clearance hole 211, which can form a temporary sealed protection effect and have a certain waterproof and dustproof function, which can effectively prevent moisture and dust from entering the socket 310 through the first clearance hole 211 and affecting the performance of the entire power socket; when in use, after the power head pin pushes away the two elastic protective sheets 212 from the opening and closing edge, the power head pin passes through the first clearance hole 211 and is plugged into the socket 310 to complete the conductive plugging action.

[0035] By setting the curved face cover 200 to form the upwardly convex waterproof cover portion 210, it can effectively prevent the accumulated water on the face cover 200 from entering the jack 310 through the first relief hole 211. It has good waterproof performance and can ensure the safety of electricity use. The thickness of the entire cover plate is uniformly equal. Compared with simply setting a raised enclosure on the face cover 200, which causes obstruction to the insertion and use of the power plug pins, the waterproof power socket of the present utility model can effectively control the thickness of the structure above the plug and conductive module 300 to be thin enough, thereby effectively ensuring that the depth of the conventional power plug pin inserted into the jack 310 during application is large enough, and further effectively ensuring that the contact effect of the plug and conductive connection during application is stable and reliable, and the conductivity is good. By setting the opening of the first relief hole 211 to be larger than the opening of the jack 310, it can provide sufficient space for the arrangement of the elastic protection pieces 212. The opposite edges of the two elastic protection pieces 212 are in contact with each other. When idle, it can effectively prevent moisture and dust from entering the jack 310 through the first relief hole 211. Even in a humid environment or when encountering a small water flow impact, it can ensure the safety and dryness of the internal circuit of the socket, and can significantly reduce the risks such as circuit short circuit and leakage. When in use, the power plug pin can push aside the elastic anti-slip pieces to achieve insertion and connection with the jack 310. Compared with the traditional use of a waterproof cover to protect the jack 310, the waterproof power socket of the present utility model is convenient to use and operate.

[0036] It can be understood that the waterproof power socket further includes a power supply circuit board 110 and a switch module 120 both installed in the bottom box 100. The face cover 200 is provided with a second relief hole 220 for making way for the switch module 120. A waterproof flange 230 is provided on the face cover 200 surrounding the second relief hole 220. The waterproof flange 230 protrudes from the surface of the face cover 200. Through the waterproof flange 230, most of the moisture can be effectively blocked from entering the socket interior through the second relief hole 220, and the waterproof performance of the overall structure can be effectively improved. The top of the switch module 120 passes through the second relief hole 220. The plug and conductive module 300 and the switch module 120 are both electrically connected to the power supply circuit board 110. The switch module 120 is used to control the conduction or disconnection of the plug and conductive module 300. Preferably, the plug and conductive modules 300 are connected in series or in parallel and then connected to the switch module 120 to form a circuit. The switch module 120 controls the power supply on-off states of the plug and conductive modules 300 overall, and the control operation is convenient and the safety performance is good.

[0037] Specifically, the top surface of the waterproof flange 230 is coplanar with the top surface of the waterproof cover portion 210, which can effectively control the height of the waterproof power socket, is convenient for application and installation, and can increase the adaptable range.

[0038] It can be understood that an indicator light 111 is provided on the power supply circuit board 110, and the face cover 200 is also provided with a light-transmitting hole 240. The light-emitting part of the indicator light 111 is located on the side of the light-transmitting hole 240 close to the bottom box 100. Preferably, a light-transmitting sheet is provided in the light-transmitting hole 240, and the light-transmitting sheet is hermetically arranged at the opening of the light-transmitting hole 240. The light emitted by the indicator light 111 during operation can pass through the light-transmitting sheet and irradiate above the light-transmitting hole 240 to form an indication effect, and the light-transmitting sheet can effectively ensure the waterproof performance of the overall structure. The indicator light 111 is electrically connected to the power supply circuit board 110, and the switch module 120 is also used to control the on-off of the indicator light 111. After being connected in series or in parallel, the respective plug-and-conduct modules 300 are connected to the switch module 120 and the indicator light 111 to form a circuit, and the switch module 120 can simultaneously control the power supply on-off states of the respective plug-and-conduct modules 300 and the indicator light 111.

[0039] It should be noted that the plug-and-conduct module 300 can specifically be set as a connector structure for inserting and conducting electricity, such as a USB-A connector, a USB-C connector, a two-pin socket connector, or a three-pin socket connector, etc.

[0040] It can be understood that the elastic protection piece 212 is a silicone sheet. Silicone has good insulation performance, which can effectively ensure the reliability of the conductive connection structure during plugging, and silicone has good elasticity and a relatively high friction coefficient. It can not only effectively improve the waterproof and dustproof performance during idling, but also, during plugging, the power plug pin can be clamped and positioned through the silicone sheet, which can effectively improve the stability of the conductive plugging structure during use.

[0041] It can be understood that a positioning frame 250 is provided around the face cover 200, and a face frame 260 is snap-fitted on the positioning frame 250. The top surface of the face frame 260 is coplanar with the top surface of the face cover 200. The face frame 260 is provided with a plurality of diversion grooves 261. The opposite ends of the diversion grooves 261 are respectively connected to the inner wall and the outer wall of the face frame 260. The diversion grooves 261 are used to divert the water accumulated on the face cover 200 to the surroundings for discharge, which can effectively reduce the probability that the liquid level on the face cover 200 is higher than the waterproof cover part 210, thereby effectively improving the waterproof performance and having good safety performance.

[0042] It can be understood that the bottom of the diversion groove 261 slopes downward from the inner wall to the outer wall of the face frame 260, which can effectively improve the water diversion and flow efficiency of the diversion groove 261 and further improve the waterproof performance of the overall structure.

[0043] It can be understood that a number of positioning posts 270 are provided at the bottom of the face cover 200, and a number of positioning slots 130 respectively matching and corresponding to each positioning post 270 are provided in the bottom box 100.

By means of the cooperation between the positioning posts 270 and the positioning slots 130, the stability of the connection structure between the face cover 200 and the lower box can be effectively improved. Preferably, through holes can be provided in the positioning slots 130 and screw holes can be provided in the positioning posts 270, and the face cover 200 and the bottom box 100 are fixed by screwing the screws through the through holes and threadedly connecting them with the screw holes.

[0044] It can be understood that a limiting retaining wall 280 is provided at the bottom of the face cover 200, and the limiting retaining wall 280 abuts against the top of the inner wall of the bottom box 100.
