Description

Technical Field

[0001] The utility model belongs to the technical field of power strip applications, and in particular relates to a waterproof power strip. Background Art

[0002] The safe use of electrical equipment is crucial in daily life and industrial production, especially in humid or wet environments such as bathrooms, kitchens, and outdoor spaces. The waterproof performance of electrical outlets is a critical issue. Traditional power strips often lack effective waterproofing, and once moisture seeps in, it can easily lead to safety hazards such as short circuits, electrical leakage, and even fire. Consequently, there is a growing demand for power strips with effective waterproofing.

[0003] Existing waterproof power strip designs often focus on improving the sealing of the housing, preventing water ingress by adding sealing gaskets and using waterproof materials. However, these methods can risk seal failure during long-term use or under extreme conditions, and often overlook effective drainage mechanisms for water once it enters. Furthermore, while some designs incorporate drainage, these are inefficient, easily leading to water accumulation and compromising safety. Summary of the Invention

[0004] The purpose of the present invention is to provide a waterproof power strip to solve the above problems.

[0005] To achieve the above objectives, the present invention provides a waterproof power strip for inserting external pins. The power strip comprises a housing, a socket, and a connection module. The housing comprises an upper cover and a lower cover that are interconnected. Several connection modules are located within the housing. The upper end of the upper cover is provided with several removable intermediate panels, each of which is provided with a socket. The pins extend into the socket and connect to the connection modules. The waterproof power strip also includes a water inlet and a water outlet. The intermediate panel is provided with a water inlet, a through-flow channel is provided in the connection module, and the lower cover is provided with several water outlets. Water flows in through the water inlet, flows through the flow channel, and flows out through the water outlet.

[0006] Furthermore, the connection module is also provided with a support frame, a fixing seat, and a wire end cabin. The support frame is connected to the upper end of the lower cover body, and one end of the support frame is horizontally connected to the wire end cabin with an upward opening. The upper end of the support frame is connected to the fixing seat, and the fixing seat is provided with a socket corresponding to the middle plate. The pins extend into the sockets of each layer in turn and form an electrical connection with the wire end cabin; the upper end of the fixing seat is covered with an middle plate, and a placement cavity for placement is provided between the two.

[0007] Furthermore, a first flow hole is provided on the fixing seat, and a second flow hole is provided at a corresponding position on the support frame; a third flow hole is provided at the bottom end of the line end cabin; the first flow hole and the second flow hole form a diversion channel, and water flows in from the water inlet, flows through the first flow hole, the second flow hole or the third flow hole in turn, and flows out from the water outlet.

[0008] Furthermore, the highest end surface of the line end cabin is lower than the highest end surface of the support frame to form a step for guiding the water flow.

[0009] Furthermore, a metal contact electrically connected to the plug pin is provided in the wire end cabin, and a protective unit is provided at the side end of the metal contact to prevent mis-insertion.

[0010] Furthermore, the protection unit includes two metal springs arranged opposite each other, wherein the bottom of one metal spring extends toward one side to form a fixed end connected to the line end chamber. The middle portion of the metal spring extends upward and approaches each other; the upper portion of the metal spring extends upward and away from each other.

[0011] Furthermore, the metal contact is connected to the protective unit via a connector. The connector has first connector portions at both ends of the connector facing the metal spring, and second connector portions extending toward the metal contact at both ends of the connector. When the pins extend into the metal contacts and contact the first connector portions, the second connector portions indirectly receive force and contact the metal contacts, completing the electrical connection between the metal contacts and the pins.

[0012] Furthermore, a blocking and limiting member is provided in the placement cavity, which covers the insertion hole of the fixing seat; the blocking and limiting member is made of a soft grease material with a certain deformation ability; the plug avoids the blocking and limiting member and extends into the fixing seat.

[0013] Furthermore, the end of the blocking and limiting member is divided into a first branch end, a second branch end and a third branch end. The first branch end is provided with an inclined groove toward the direction of the socket, so that the pin extends into the socket at the upper end along the guidance of the inclined groove; the second branch end and the third branch end are provided with blocking horizontal bars to block the socket at the lower end.

[0014] The above one or more technical solutions in the waterproof power strip provided by the embodiment of the present invention have at least the following technical effects:

[0015] In this design, users insert the electrical plugs into the waterproof power strip to complete the electrical connection. In humid environments, moisture enters the housing through the water inlet. Once in the diversion channel, the moisture flows along a pre-set path under the influence of gravity and eventually drains out of the water outlet, keeping the housing dry and preventing damage to electrical components. The water inlet and diversion channel design effectively prevents moisture accumulation within the housing and promptly removes any moisture that does enter, reducing safety risks such as short circuits and leakage, ensuring the safety of both users and electrical equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0032] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0033] In the embodiment of the present utility model, Figures 1 to 3As shown, this case provides a waterproof power strip for inserting external pins. It includes a housing 100, a socket 140, and a connection module 300. The housing 100 is composed of an upper cover 110 and a lower cover 120 that are connected to each other. Several connection modules 300 are located within the housing 100. The upper end of the upper cover 110 is provided with several detachable intermediate panels 130. The intermediate panels 130 are provided with sockets 140. The pins extend into the sockets 140 and connect to the connection modules 300. The waterproof power strip also includes a water inlet 200 and a water outlet 210. The intermediate panel 130 is provided with a water inlet 200. The connection module 300 is provided with a through-flow diversion channel 220. The lower cover 120 is provided with several water outlets 210. Water flows in through the water inlet 200, flows through the diversion channel 220, and flows out through the water outlet 210.

[0034] Specifically, the user inserts the electrical plug into the waterproof power strip to complete the electrical connection. In a humid environment, moisture enters the housing 100 through the water inlet 200. Once in the diversion channel 220, the moisture flows along a pre-set path under the action of gravity and finally exits through the water outlet 210, keeping the interior of the housing 100 dry and preventing damage to the electrical components. The design of the water inlet 200 and the diversion channel 220 effectively prevents moisture accumulation within the housing 100, promptly removes any moisture that does enter, reduces safety hazards such as short circuits and leakage, and ensures the safety of both the user and the electrical equipment.

[0035] In another embodiment of the utility model, Figures 3-5As shown, the connection module 300 is further provided with a support frame 310, a fixing seat 320, and a wire end cabin 330. The support frame 310 is connected to the upper end of the lower cover body 120, and one end of the support frame 310 is horizontally connected to the wire end cabin 330 with an upward opening. The upper end of the support frame 310 is connected to the fixing seat 320. The fixing seat 320 is provided with a socket 140 corresponding to the middle plate 130. The pins extend into the sockets 140 of each layer in turn and form an electrical connection with the wire end cabin 330; the upper end of the fixing seat 320 is covered with the middle plate 130, and a placement cavity 340 for placement is provided between the two. The fixing base 320 is provided with a first flow hole 230, and the support frame 310 is provided with a second flow hole 240 at a corresponding position. A third flow hole 250 is provided at the bottom end of the cable end pod 330. The first flow hole 230 and the second flow hole 240 form a diversion channel 220. Water flows in through the water inlet 200, flows through the first flow hole 230, the second flow hole 240, or the third flow hole 250, and flows out through the water outlet 210. Specifically, when water enters the waterproof power strip through the water inlet 200, it flows along the diversion channel 220. First, it passes through the first flow hole 230 on the fixing base 320 and enters the second flow hole 240 of the support frame 310, or flows directly to the third flow hole 250 of the cable end pod 330. Ultimately, the water gathers at the water outlet 210 of the lower cover 120 and is discharged. When adding flow holes, it is necessary to ensure that the waterproof and sealing performance between the various components is not affected. The joints between the fixing base 320, the support frame 310 and the wire end cabin 330 should be treated with sealing materials or sealing structures to prevent moisture from penetrating into the interior through the gaps.

[0036] In another embodiment of the utility model, Figure 5 As shown, the highest end surface of the line end cabin 330 is lower than the highest end surface of the support frame 310 to form a step for guiding the water flow, which is beneficial to the conduction of water flow.

[0037] In another embodiment of the utility model, Figure 7As shown, the terminal housing 330 also houses metal contacts 350 electrically connected to the plug pins. A protective unit 500 is located on the side of the metal contacts 350 to prevent mis-insertion. The protective unit 500 includes two opposing metal springs 510. A fixed end 520 extends from the bottom 511 of one metal spring 510, which is connected to the terminal housing 330. The middle portion 512 of the metal springs 510 extends upward and toward each other; the upper portion 513 of the metal springs 510 extends upward and away from each other. The metal contacts 350 are also connected to the protective unit 500 via a connector 530. The first connecting parts 531 are respectively provided at the two positive ends of the connecting member 530 in the direction of the metal spring 510, and the second connecting parts 532 are respectively extended in the direction of the metal contact 350 at the two negative ends of the connecting member 530. After the pin is inserted into the metal contact 350 and contacts the first connecting part 531, the second connecting part 532 is indirectly subjected to force and contacts the metal contact to complete the electrical connection between the metal contact 350 and the pin.

[0038] Specifically, the terminal compartment 330 is equipped with a protective element 500 to prevent mis-insertion. If a non-standard plug, hardware, or a tweezers ejector is removed, its upper portion 513 of the metal spring 510 will initially block the ejector due to its large width, preventing it from entering the terminal compartment 330. Alternatively, if the ejector is removed due to its small width, it will only contact the first connection portion 531 on one end, failing to complete the circuit. Therefore, only a standard plug is inserted, pushing apart the two metal springs 510 and simultaneously connecting the first connection portion 531. This allows the second connection portion 532 to precisely contact the metal contact 350, completing the circuit closure, ensuring high safety and precision.

[0039] In another embodiment of the utility model, Figure 6As shown, a blocking member 400 is provided within the placement cavity 340. The blocking member 400 covers the socket 140 of the fixing base 320. The blocking member 400 is made of a soft, deformable material. The pin avoids the blocking member 400 and extends into the fixing base 320. The blocking member 400 has a first branch end 410, a second branch end 420, and a third branch end 430. The first branch end 410 is provided with an inclined groove directed toward the socket 140, allowing the pin to extend into the upper socket 140 along the inclined groove. The second branch end 420 and the third branch end 430 are provided with blocking bars to block the lower socket 140. Specifically, the blocking member 400 is made of a soft, deformable material (such as silicone or rubber). This material can deform when subjected to external force but quickly return to its original shape. The first branch end 410 is provided with an inclined groove facing the direction of the socket 140, and this inclined groove plays a guiding role. When the pin approaches the socket 140 from above, it will first contact the inclined groove and slide smoothly into the socket 140 along the guidance of the groove. The design of the inclined groove helps to reduce the friction between the pin and the blocking limiter 400, while ensuring that the pin can be accurately aligned and not easily inserted off-center, thereby playing a fool-proofing effect. The second branch end 420 and the third branch end 430 are provided with blocking bars, which correspond to the lower edge of the socket 140. When the pin is correctly inserted into the socket 140, the blocking bar will block the socket 140 below, preventing other objects (such as foreign objects or fingers inserted by mistake) from entering the socket 140 below, thereby improving safety during use.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
