Description

Technical Field

[0001] This utility model relates to the field of power strip technology, specifically a waterproof shielded extension cord power strip with American standard socket structure. Background Technology

[0002] A power strip is a multi-socket outlet with a cord, also known as a power strip or power strip, and its technical name is a power cord extension assembly or extension cord socket.

[0003] For example, announcement number CN220172443U, entitled "Power Strip Base Shell and Power Strip", includes an integrally formed shell. The shell includes a base plate, two inner side plates spaced apart on both sides of the base plate, and two outer side plates spaced apart on both sides of the base plate. The inner and outer side plates are located on the same side of the base plate, and the two outer side plates are located outside the two inner side plates respectively, with a gap between them. The outer side plates are inclined outward relative to the inner side plates, and at least part of the outer side plates are elastically deformable. In this utility model, the distance from the outer surface of the end portion of one outer side plate to the outer surface of the end portion of the other outer side plate is greater than the width of the mounting hole pre-drilled at a designated position. In this way, the power strip can be engaged with the mounting hole by the elastic deformation of the outer side plates, improving the stability and firmness of the power strip installation and facilitating quick assembly and disassembly for temporary use.

[0004] The existing power strips do not have a waterproof shielding structure inside, which causes leakage when the copper contacts inside the power strip are soaked in water, potentially causing serious damage to the user's life and property. Therefore, this invention proposes a waterproof shielding extension cord with an American standard socket structure to meet the current needs. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof shielded extension cord with an American standard socket structure to solve the problem mentioned in the background art that the existing power strips do not have a waterproof shielding structure inside when in use, which causes leakage when the copper plates inside the power strip are soaked in water, and may cause serious damage to the life and property safety of users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof shielded extension cord for American standard sockets, comprising: a housing, a shielding chamber assembly installed inside the housing, a copper strip assembly installed inside the shielding chamber assembly, and a waterproof shielding assembly installed on the upper surface of the shielding chamber assembly.

[0007] Preferably, the shielding chamber assembly includes a shielding chamber body, a shielding chamber cover is installed on the top of the shielding chamber body, and mounting grooves are provided on both sides of the upper surface of the shielding chamber cover.

[0008] Preferably, the waterproof shielding assembly includes a leakage-shielding copper sheet, which is installed in the assembly groove.

[0009] Preferably, the waterproof shielding assembly further includes a sealing silicone pad installed on the upper surface of the shielding leakage copper sheet, wherein the outer wall of the sealing silicone pad is provided with a mating hole, and a sealing silicone sheet is disposed inside the mating hole.

[0010] Preferably, the copper strip assembly includes a ground copper strip, a live copper strip, and a neutral copper strip, and the copper strip assembly, including the ground copper strip, the live copper strip, and the neutral copper strip, is installed in the groove of the shielding chamber.

[0011] Preferably, shielding copper strip frames for live wires are provided on both sides above the neutral wire copper strip.

[0012] Preferably, the housing includes a bottom cover, a front cover is mounted on the top of the bottom cover, a power-off switch and a power cord are mounted on the outer wall of one side of the front cover, and a USB charging port is mounted on the other side of the front cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the shielding copper sheet is embedded in the assembly groove, covering the interface at the shielding chamber. A sealing silicone pad adheres to the surface of the copper sheet, and a mating hole is provided for the plug to be inserted. The sealing silicone pad blocks direct contact between water and the copper sheet, preventing the formation of a leakage circuit. The sealing silicone pad is located inside the mating hole to form a dynamic seal. When not plugged in, the sealing silicone pad closes the mating hole to isolate water vapor and dust. When plugged in, the plug squeezes the sealing silicone pad to deform it, and at the same time, the sealing silicone pad expands under pressure to fill the gap, thereby effectively improving the waterproof, shielding, and leakage prevention effect at this location.

[0015] (2) In this utility model, by setting the shielding cover and the shielding chamber body, an independent sealed chamber can be formed inside the shell, and the internal copper strip assembly is completely wrapped in the independent chamber. Even if water enters the shell, the water cannot contact the conductive parts, thus preventing leakage from the source. Even after water enters, the waterproof shielding and leakage prevention effects are improved. The modular design that can be disassembled and assembled is convenient for assembly and maintenance, and reduces production costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1 , Figure 2 This utility model provides an embodiment of a waterproof shielded extension cord for American standard sockets, comprising: a housing 1, the housing 1 including a bottom cover 101, a front cover 102 mounted on the top of the bottom cover 101, a power-off switch 103 and a power cord 104 mounted on one side of the outer wall of the front cover 102, and a USB charging port 105 mounted on the other side of the front cover 102; the housing 1 is composed of the bottom cover 101 and the front cover 102, and adopts an upper and lower split assembly design, which facilitates installation and disassembly, and facilitates subsequent maintenance of internal modules. At the same time, the cavity generated inside the housing 1 is convenient to accommodate the shielding chamber assembly 2, so that the housing 1 can protect the shielding chamber assembly 2 and improve external protection. The power-off switch 103 is convenient to cut off in case of water or overload.

[0023] Among them, such as Figure 3 , Figure 4 As shown, a shielding chamber assembly 2 is installed inside the housing 1, a copper strip assembly 3 is installed inside the shielding chamber assembly 2, and a waterproof shielding assembly 4 is installed on the upper surface of the shielding chamber assembly 2. The shielding chamber assembly 2 includes a shielding chamber body 201, and a shielding chamber cover 202 is installed on the top of the shielding chamber body 201. Assembly grooves 203 are provided on both sides of the upper surface of the shielding chamber cover 202. Through the arrangement of the shielding chamber cover 202 and the shielding chamber body 201, an independent sealed chamber can be formed inside the housing 1, completely enclosing the internal copper strip assembly 3 in the independent chamber. Even if water enters the housing 1, the water cannot contact the conductive parts, thus preventing leakage from the source. Even after water enters, the waterproof shielding and leakage prevention effects are improved. The modular design that can be disassembled and installed facilitates assembly and maintenance, reduces production costs, and the assembly grooves 203 are used to fix the waterproof shielding assembly 4.

[0024] Furthermore, such as Figure 4 As shown, the waterproof shielding assembly 4 includes a shielding copper sheet 401 for leakage current. The shielding copper sheet 401 is installed in the assembly groove 203. The waterproof shielding assembly 4 also includes a sealing silicone pad 402 installed on the upper surface of the shielding copper sheet 401. The outer wall of the sealing silicone pad 402 is provided with a mating hole 403, and a sealing silicone pad 404 is provided inside the mating hole 403. The shielding copper sheet 401 is embedded in the assembly groove 203, covering the interface at the shielding compartment. The sealing silicone pad 402 is attached to the surface of the copper sheet and the mating hole 403 is provided for the plug to be inserted. The sealing silicone pad 404 blocks the direct contact between the water and the copper sheet, avoiding the formation of a leakage circuit. The sealing silicone sheet 404 is located inside the mating socket 403 to form a dynamic seal. When not plugged in, the sealing silicone sheet 404 closes the mating socket 403 to isolate moisture and dust. When plugged in, the plug squeezes the sealing silicone sheet 404 to deform it, and at the same time, the sealing silicone pad 402 expands under pressure to fill the gap, thereby effectively improving the waterproof, shielding and leakage prevention effect at this point.

[0025] Please see Figure 4 The copper strip assembly 3 includes a ground copper strip 301, a live copper strip 302, and a neutral copper strip 303. All three are installed in the groove of the shielding chamber 201. Shielding live copper sheet frames 304 are provided on both sides above the neutral copper strip 303. The ground copper strip 301, live copper strip 302, and neutral copper strip 303 are all installed in the shielding chamber 201. The shielding live copper sheet frames 304 surround the live copper strip 302 to suppress electromagnetic radiation, reduce interference to electronic components such as the USB charging port 105, improve charging stability, and extend the life of the device.
