Description

Technical Field

[0001] This invention relates to the field of power strip technology, and more specifically to a dual-state waterproof power strip. Background Technology

[0002] As an important interface for daily electricity use, the safety of power sockets is directly related to the safety of users' lives and property and the stable operation of electrical systems.

[0003] Traditional sockets generally have two prominent hidden dangers: Firstly, their waterproof and dustproof capabilities are insufficient. Ordinary sockets are often directly exposed to the environment, making them susceptible to dust, moisture, and even liquids from penetrating the socket and causing electrical short circuits, insulation degradation, or corrosion of metal parts. This safety hazard is particularly pronounced in humid or dusty environments such as kitchens, bathrooms, and outdoors. Some existing sockets with waterproof features typically only have a simple rubber gasket on the panel or a flat rubber sleeve behind the socket. Their sealing effect is limited, and the sleeve is easily worn or torn by the plug pins during repeated insertions and removals, causing a rapid decline in sealing performance.

[0004] Secondly, there is the risk of misinsertion. In daily life, metal objects or individual prongs of electrical plugs may accidentally insert into a socket, exposing live parts and easily causing serious accidents such as short circuits, arcing, electric shocks, or even fires. Although some socket products on the market use mechanical linkages to prevent misinsertion, these structures often rely on complex moving parts and precise fits. After long-term use, they are prone to malfunction due to wear, deformation, or obstruction by foreign objects, resulting in insufficient reliability. Furthermore, the lack of clear tactile feedback during operation makes it difficult for users to detect misoperation in a timely manner, reducing the effectiveness of safety warnings.

[0005] Therefore, there is an urgent need for a socket solution that is compact in structure, reliable in operation, and can simultaneously achieve long-term dynamic sealing and efficient prevention of misinsertion, so as to improve the inherent safety and reliability of sockets in various usage environments. Summary of the Invention

[0006] To improve the safety of sockets, this invention provides a dual-state waterproof socket.

[0007] The technical solution adopted in this invention is as follows: A dual-state waterproof plug includes a housing and at least one pair of live wire sockets and neutral wire sockets disposed within the housing. The housing panel has corresponding live wire sockets and neutral wire sockets. A common slider is provided below the live wire socket and the neutral wire socket. The top of the slider has two inclined guide surfaces corresponding to the live wire socket and the neutral wire socket, respectively. The bottom of the slider has a slide rail. The housing has a slide groove adapted to the slide rail. The slider slides horizontally through the cooperation of the slide rail and the slide groove. A sealing limiting sleeve is provided below each of the live wire socket and the neutral wire socket. The lower surface of the sealing limiting sleeve is a sealing slope that fits against the inclined guide surfaces of the slider, used to press against the inclined guide surfaces to form a static seal when no plug is inserted. A sealing limiting hole is provided in the center for the plug to pass through, used to form a dynamic seal with the plug through an interference fit when the plug is inserted.

[0008] Preferably, it further includes a first elastic element that resets the slider, the force of which causes the slider to tend to move below the live wire socket and the neutral wire socket.

[0009] Preferably, the first elastic element includes at least two cylindrical springs symmetrically arranged on both sides of the slide rail, and the slider is provided with a first guide post for positioning the first elastic element.

[0010] Preferably, each of the inclined guide surfaces is provided with a resilient button assembly that can be inserted into the sealing limiting hole and can be depressed by the plug foot to retract; when only one plug foot is inserted into the live wire socket or the neutral wire socket and the single resilient button assembly is depressed, the single resilient button assembly retracts from the corresponding sealing limiting hole, while the other resilient button assembly remains restricted by its corresponding sealing limiting hole, preventing the slider from moving as a whole; when two plug feet are inserted into the live wire socket and the neutral wire socket respectively and the two resilient button assemblies are depressed, the two resilient button assemblies retract from the corresponding sealing limiting holes, and the slider moves as a whole along the guide surface of the inclined guide surface under the push of the plug feet until the two plug feet are electrically connected to the live wire socket and the neutral wire socket respectively.

[0011] Preferably, the elastic button assembly includes a rigid button and a second elastic element that provides an upward restoring force thereon; the slider is equipped with a lower cover plate, which is locked to the slider to form a receiving cavity for accommodating the button and the second elastic element; the lower end of the button is provided with a locking foot to limit the up-and-down movement of the button within the receiving cavity; the lower cover plate is provided with an upwardly extending second guide post, the lower end of the second elastic element abuts against and is sleeved on the second guide post, and the upper end abuts against the interior of the button.

[0012] Preferably, the top of the protruding button is an inclined surface aligned with the direction of the inclined guide surface, and its initial tilt angle is greater than the initial tilt angle of the inclined guide surface.

[0013] Preferably, the sealing inclined surface is provided with a first annular protrusion surrounding the sealing limiting hole, and the corresponding annular contact area on the inclined guide surface is pressed into contact with the first annular protrusion to form the static seal.

[0014] Preferably, the end of the pin forms a friction zone on the inclined guide surface, the friction zone has two protrusions, and the overlapping area of ​​the annular contact area and the friction zone is located in the gap between the two protrusions; when the pin is inserted, its end slides along the friction zone, contacts and is supported by the protrusions, and passes over the annular contact area.

[0015] Preferably, the inner wall of the sealing limiting hole is provided with at least one second annular protrusion, which forms the dynamic seal by interfering with the plug when the plug is inserted.

[0016] Preferably, a pair of magnetic adsorption elements are provided between the housing and the slider, and when the slider is in the initial position, the magnetic adsorption elements are in the optimal adsorption position.

[0017] The present invention has the following beneficial effects: 1. Dual-state sealing, waterproof and dustproof, long-lasting and reliable: The integrated sealing limit sleeve achieves two-stage synergistic sealing; when not inserted, the sealing bevel is pressed against the inclined guide surface of the slider, especially through the tight line contact between the first annular protrusion and the annular contact area, forming a reliable static seal that effectively blocks dust and moisture; when inserted, the second annular protrusion on the inner wall of the sealing limit hole is interference-fitted with the pin, forming a dynamic seal to prevent liquid intrusion; 2. Wear-resistant sealing structure: To address the damage to the sealing surface caused by insertion and removal friction, a friction zone and protrusions are specially designed on the inclined guide surface of the slider. When the pin is inserted, its end is supported and lifted by the protrusions, thereby bypassing and avoiding direct scraping with critical sealing parts, solving the problem of easy wear of the sealing surface and extending the service life of the sealing assembly; 3. Reliable anti-misinsertion mechanism: Through the stable guidance of the slide rail at the bottom of the slider and the slide groove of the housing, and the mechanical interlock between the elastic convex button assembly and the sealing limit hole on the sealing limit sleeve, a forced synchronous unlocking logic is achieved. Only when both pins press down on the two elastic convex button assemblies at the same time, causing them to exit from the sealing limit hole, can the slider unlock and move to connect the circuit. Any single-pole insertion will cause the slider to be unable to move because one side of the convex button is still limited. Physically, the risk of misinsertion and power-on is eliminated, resulting in high reliability. 4. Compact Structure: The slider, as an integrated functional component, simultaneously supports the inclined guide surface, the convex button receiving cavity, the slide rail, and the reset elastic element mounting structure; the sealing limit sleeve integrates both limiting and double sealing functions. The highly integrated and compact layout of the components facilitates multiple safety protections within a standard socket space. 5. Clear and smooth operation: When inserting a single pole, the user will feel a clear mechanical resistance, providing immediate error feedback. When inserting a double pole correctly, the optimized slope on the top of the convex button effectively reduces the initial resistance, allowing the slider to move smoothly under the push of the pin. During reset, the synergistic effect of the first elastic element and the magnetic adsorption element ensures that the slider returns to its initial position accurately and stably with a sense of adsorption. The overall operation is clear, smooth, and has a high-quality feel. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0025] In the embodiments, such as Figures 1-5 As shown, a dual-state waterproof socket includes a housing 1 and at least one pair of live wire sockets 2 and neutral wire sockets 3 disposed within the housing 1. The panel of the housing 1 has corresponding live wire sockets 1.1 and neutral wire sockets 1.2. A common slider 4 is provided below the live wire sockets 1.1 and 1.2. The top of the slider 4 has two inclined guide surfaces 4.1 corresponding to the live wire sockets 1.1 and 1.2 respectively, and the bottom of the slider 4 has a slide rail portion 4.2. The housing 1 contains a component adapted to the slide rail portion 4.2. The sliding groove 1.3 is provided, and the slider 4 slides horizontally through the cooperation of the slide rail part 4.2 and the sliding groove 1.3. A sealing limit sleeve 5 is provided below the live wire socket 1.1 and the neutral wire socket 1.2. The lower surface of the sealing limit sleeve 5 is a sealing slope 5.1 that fits against the inclined guide surface 4.1 of the slider 4, which is used to press against the inclined guide surface 4.1 to form a static seal when the plug is not inserted. A sealing limit hole 5.2 is provided in the center for the plug to pass through, which is used to form a dynamic seal by interference fit with the plug when the plug is inserted. The housing 1 is assembled from an upper housing 1.4, a middle housing 1.5, and a lower housing 1.6. The live wire socket 1.1 and the neutral wire socket 1.2 are located on the upper housing 1.4. The sealing and limiting sleeve 5 is fixed in the retaining holes within the upper housing 1.5 by two side latches 5.6. The slider 4 is assembled between the upper housing 1.4 and the middle housing 1.5. The sliding groove 1.3 is located on the middle housing 1.5. The live wire socket 2 and the neutral wire socket 3 are located on the lower housing 1.6. Through the integrated coupling design of the slider 4 and the sealing and limiting sleeve 5, both physical anti-misinsertion and dual-state sealing are achieved simultaneously in a single compact structure. The integrated sealing and limiting sleeve 5 achieves two-stage synergistic sealing. When not inserted, its sealing bevel 5.1 is pressed against the slider's inclined guide surface 4.1, and in particular, the tight line contact between the first annular protrusion 5.3 and the annular contact area 4.5 forms a reliable static seal, effectively blocking dust and moisture. During insertion, the second annular protrusion 5.4 on the inner wall of the sealing limiting hole 5.2 makes an interference fit with the pin, forming a dynamic seal to prevent liquid intrusion. This dual-state seal, combining dynamic and static elements, significantly improves the socket's environmental adaptability.

[0026] In the embodiments, such as Figures 2-4 As shown, it also includes a first elastic element 6 that resets the slider 4. The force of the first elastic element 6 causes the slider 4 to tend to move below the live wire socket 1.1 and the neutral wire socket 1.2. After the plug 11 is pulled out, the reset force of the first elastic element 6 can automatically and accurately push the slider 4 back to the initial position below the live wire socket 1.1 and the neutral wire socket 1.2, ensuring that the anti-misinsertion mechanism is in the correct ready-to-trigger state before each insertion and removal operation, thus ensuring the continuous effectiveness of the function and the consistency of the action.

[0027] In the embodiments, such as Figure 2 , Figure 4 As shown, the first elastic element 6 includes at least two cylindrical springs symmetrically arranged on both sides of the slide rail 4.2. The slider 4 is provided with a first guide post 4.3 for positioning the first elastic element 6. The cylindrical springs symmetrically arranged on both sides of the slide rail 4.2 provide a symmetrical and balanced restoring force to the slider 4, preventing the slider 4 from deflecting or jamming due to uneven force during the restoring process. The first guide post 4.3 plays a positioning and guiding role for the cylindrical springs, preventing the springs from buckling or shifting during compression / rebound, ensuring the long-term reliability and smoothness of the restoring action.

[0028] In the embodiments, such as Figures 2-4 As shown, each inclined guide surface 4.1 is provided with a resilient button assembly that can be inserted into a sealing limiting hole 5.2 and can be depressed out by the plug foot. When only one plug foot is inserted into the live wire socket 1.1 or the neutral wire socket 1.2 and the single resilient button assembly is depressed, the single resilient button assembly is depressed out of the corresponding sealing limiting hole 5.2, while the other resilient button assembly is still restricted by its corresponding sealing limiting hole 5.2, preventing the slider 4 from moving horizontally as a whole. When two plug feet are inserted into the live wire socket 1.1 and the neutral wire socket 1.2 respectively and the two resilient button assemblies are depressed, the two resilient button assemblies are depressed out of the corresponding sealing limiting holes 5.2, and the slider 4 moves horizontally as a whole along the guide surface 4.1 under the push of the plug feet until the two plug feet are electrically connected to the live wire socket 2 and the neutral wire socket 3 respectively. The slider 4 forms a stable double-rail guide by cooperating with the sliding groove 1.3 in the housing through at least two sliding rail parts 4.2 at the bottom, allowing the slider 4 to slide smoothly horizontally. The two elastic convex button assemblies, along with the corresponding limiting sleeve 5 and sealing limiting hole 5.2, constitute a mechanical interlock logic: the movement restriction on the slider 4 can only be released when both pins 11 simultaneously press down on the two elastic convex button assemblies, causing them to both exit from the sealing limiting hole 5.2. This structure physically forces bipolar synchronous insertion, eliminating the risk of single-pole mis-insertion connecting the circuit. The anti-mis-insertion logic is simple, direct, and reliable.

[0029] In the embodiments, such as Figures 2-4As shown, the elastic button assembly includes a rigid button 7 and a second elastic element 8 that provides an upward restoring force. The slider 4 is equipped with a lower cover plate 9, which is securely connected to the slider 4, together forming a receiving cavity 4.4 that accommodates the button 7 and the second elastic element 8. The lower end of the button 7 has a locking foot 7.1, limiting the button 7's vertical movement within the receiving cavity 4.4. The lower cover plate 9 has an upwardly extending second guide post 9.1, with the lower end of the second elastic element 8 abutting against and sleeved on the second guide post 9.1, and its upper end abutting against the interior of the button 7. The rigid button 7 has good wear resistance and a long service life due to direct contact with the pin 11. The locking foot 7.1 at the lower end of the button 7 cooperates with the receiving cavity 4.4 inside the slider 4, limiting its vertical movement within a reasonable range. This ensures sufficient pressing stroke for unlocking while preventing the button 7 from excessively popping out or falling out of the slider 4, resulting in a robust and reliable structure. The lower cover plate 9 provides a stable and sealed housing space for the convex button 7 and the second elastic element 8. The second guide post 9.1 on the lower cover plate 9 provides precise guidance and support for the second elastic element 8, ensuring that its force always acts perpendicularly on the convex button 7, making the up-and-down movement of the convex button 7 more stable and smooth, and extending the service life of the elastic element.

[0030] In the embodiments, such as Figures 2-4 As shown, the top of the protruding button 7 is an inclined surface aligned with the direction of the inclined guide surface 4.1, and its initial tilt angle is greater than that of the inclined guide surface 4.1. This larger initial tilt angle allows the pin 11 to apply force with a smaller contact area and a steeper angle upon initial contact, converting some of the downward pressure into a component force driving the protruding button 7 downwards. This reduces the initial resistance of the pressing operation, improves the feel, and ensures that the protruding button 7 can be pressed down sensitively and smoothly, enhancing the response speed and reliability of the entire unlocking action.

[0031] In the embodiments, such as Figures 4-5 As shown, a first annular protrusion 5.3 surrounds the sealing limiting hole 5.2 on the sealing inclined surface 5.1. The corresponding annular contact area 4.5 on the inclined guide surface 4.1 presses against the first annular protrusion 5.3 to form a static seal. The pressing contact between the first annular protrusion 5.3 and the annular contact area 4.5 optimizes the static seal into a line contact or narrow surface contact, which can generate a greater contact pressure under the same clamping force, significantly improving the reliability of the static seal and the durability of the sealing interface.

[0032] In the embodiments, such as Figures 4-5As shown, the end of the pin forms a friction zone 4.6 on the inclined guide surface 4.1. The friction zone 4.6 has two protrusions 4.7. The overlapping area of ​​the annular contact area 4.5 and the friction zone 4.6 is located in the gap between the two protrusions 4.7. When the pin is inserted, its end slides along the friction zone 4.6, contacts and is supported by the protrusions 4.7, and passes over the annular contact area 4.5. During the insertion of the pin 11, its end can avoid direct scraping with the critical annular contact area 4.5 below. This structure isolates the friction path of the pin 11 from the sealing area, solves the technical problem of wear and failure of the sealing surface due to repeated friction, and greatly extends the service life of the sealing assembly.

[0033] In the embodiments, such as Figure 5 As shown, the inner wall of the sealing limiting hole 5.2 is provided with at least one second annular protrusion 5.4, which forms a dynamic seal with the pin through an interference fit when the pin is inserted. The second annular protrusion 5.4 on the inner wall of the sealing hole 5.2 optimizes the dynamic seal to line contact or narrow surface contact, and the multiple protrusions further improve reliability.

[0034] In the embodiments, such as Figure 2 , Figure 4 As shown, a pair of magnetic adsorption components 10 are provided between the housing 1 and the slider 4. When the slider 4 is in its initial position, the magnetic adsorption component 10 is in its optimal adsorption position. Specifically, one magnetic adsorption component 10 is embedded in the slider 4 and moves with the slider 4, while the corresponding other magnetic adsorption component 10 is fixed to the upper housing 1.4. When the slider 4 returns to its initial position, the magnetic attraction makes it firmly adsorbed and positioned. This provides a clear, slight "click" adsorption feel, giving the user clear feedback on the reset position; moreover, the magnetic attraction assists the first elastic component 6 in overcoming the static friction force inside the mechanism, ensuring that the slider 4 can be completely and accurately reset; in addition, when the socket is subjected to vibration or tilting, the magnetic attraction can prevent the slider 4 from accidentally shifting, further enhancing the stability and reliability of the mechanism.

[0035] Obviously, the above embodiments of the present invention are merely illustrative examples to illustrate the invention and are not intended to limit the implementation of the invention. Other obvious variations or modifications derived from the essential spirit of the invention still fall within the protection scope of the invention.
