Detailed Implementation

[0036] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0037] Sockets are typically connected to the plugs of loads to provide power. The plug-and-socket design of sockets facilitates the connection and disconnection of power to the load. In addition, some sockets have short-circuit protection and / or overload protection functions. When an overload or short circuit occurs in the circuit, the socket will cut off the power in time to protect the electrical equipment, which can also serve as a protective installation.

[0038] like Figures 1-11As shown, the socket includes a socket base 1, a first cover 2, and at least one set of plug sleeve assemblies 3. The plug sleeve assemblies 3 are installed inside the socket base 1. The first cover 2 covers the socket base 1. The first cover 2 includes at least one set of first plug holes. The at least one set of first plug holes corresponds one-to-one with the at least one set of plug sleeve assemblies 3. The plug passes through the first plug hole and is plugged into the plug assembly to connect or disconnect the circuit.

[0039] The plug assembly 3 includes at least two clamping arms, the plug includes at least two pins, the plug hole includes at least two first pin holes, and the at least two pins pass through the at least two first pin holes and are inserted into the at least two clamping arms. The plug assembly 3 also includes a terminal block electrically connected to the clamping arms for fixing external wires.

[0040] like Figure 1 As shown, this application provides a waterproof socket, which further includes a resilient waterproof component 4 located inside the socket, specifically between the socket sleeve assembly 3 and the first cover 2. The resilient waterproof component 4 includes at least one set of second plug holes, each second plug hole including at least two second pin holes. The at least one set of first plug holes and the at least one set of second plug holes correspond one-to-one in the thickness direction of the socket. The thickness direction of the socket is also... Figure 1 The vertical direction in the middle.

[0041] like Figures 2-3d As shown, the upper surface of the elastic waterproof component 4 is a planar structure. The back side of the first cover 2 (the side facing the elastic waterproof component 4) includes a planar portion that fits tightly against the upper surface of the elastic waterproof component 4. The elastic waterproof component 4 and the first cover 2 fit tightly together to achieve a waterproof effect. Figure 2 This is a structural diagram of the back of the socket. Figures 3a-3b These are, respectively, a front view, a sectional view, a rear view, and a structural schematic diagram of the elastic waterproof component 4.

[0042] Specifically, the area of ​​the second pin hole of the elastic waterproof component 4 is smaller than the cross-sectional area of ​​the pin. After the pin is inserted into the second pin hole, it is tightly wrapped by the second pin hole to achieve a waterproof effect.

[0043] Furthermore, such as Figure 3a , Figure 3c As shown, both the second pin hole and the pin cross-section are rectangular structures. The length of the second pin hole is less than the length of the pin cross-section, and the width of the second pin hole is less than the width of the pin cross-section.

[0044] Preferably, the elastic waterproof component 4 is made of silicone, which has good elasticity and also has the effect of insulation and waterproofing.

[0045] Preferred, such as Figure 1 and Figure 4 As shown, the socket also includes a second cover 5, which is located between the first cover 2 and the socket base 1. The second cover 5 and the first cover 2 clamp the elastic waterproof component 4. Specifically, the elastic waterproof component 4 is installed on the upper surface of the second cover 5 (facing the first cover 2). Preferably, the elastic waterproof component 4 can be installed on the upper surface of the second cover 5 by a dispensing process. The second cover 5 includes at least one set of third plug holes, which includes at least two third pin holes. The position of the at least one set of third plug holes corresponds to the position of the at least one set of second plug holes. The plug can sequentially pass through the first plug hole of the first cover 2, the second plug hole of the elastic waterproof component 4, and the third plug hole of the second cover 5 to connect with the socket sleeve assembly 3.

[0046] Compared to existing technologies, this application incorporates an elastic waterproof component 4 inside the socket. The area of ​​the second pin hole in the elastic waterproof component 4 is smaller than the cross-sectional area of ​​the pin. After the elastic waterproof component 4 is tightly fitted with the first cover 2, the pin is tightly wrapped by the second pin hole after being inserted, achieving a waterproof effect. The second cover 5 facilitates the installation and fixation of the elastic waterproof component 4, while further enhancing the waterproof effect and structural strength of the socket, preventing deformation of the socket when the plug is inserted. Figure 4 This is a schematic diagram of the structure of the back of the second cover 5 in the embodiment of this application.

[0047] Specifically, the positions of the first plug hole, the second plug hole, and the third plug hole mentioned above correspond, and the pins on the plug can pass through in sequence and connect to the clamping arm in the plug sleeve assembly 3. For ease of explanation, the first plug hole, the second plug hole, and the third plug hole mentioned above can be uniformly replaced by plug hole, and the first pin hole, the second pin hole, and the third pin hole mentioned above can be uniformly replaced by pin hole. The plug hole includes at least two pin holes, which are respectively the L pole pin hole and the N pole pin hole. When there are three pin holes, the three pin holes also include a ground pin hole for load grounding.

[0048] Preferred, such as Figure 4 and Figure 11 As shown, the second cover 5 and the socket base 1 are snap-fit ​​connected. The back of the second cover 5 includes two limiting plates 52. The socket base 1 is installed between the two limiting plates 52. At least one first limiting part 53 is provided on the limiting plate 52. At least one second limiting part 11 is provided on each side of the socket base 1. The first limiting part 53 and the second limiting part 11 cooperate to limit the movement. The first limiting part 53 and the second limiting part 11 can be a snap-fit ​​protrusion and a snap-fit ​​groove, or they can be a snap-fit ​​protrusion and a snap-fit ​​through hole, respectively.

[0049] Furthermore, such as Figure 4As shown, the back of the second cover 5 also includes a plurality of third limiting parts. The third limiting part includes a first limiting notch 54. The side of the socket base 1 is stuck in the first limiting notch 54, limiting the socket base 1 to shake. Preferably, a first inclined surface 55 is provided at the position of the first limiting part 53 of the second cover 5. The first inclined surface 55 facilitates the side of the socket base 1 to slide into the two limiting plates 52 of the second cover 5.

[0050] In this embodiment, as Figure 4 As shown, the second cover 5 includes four first limiting parts 53, four first limiting notches 54 and four first inclined surfaces 55 located on both sides of the two limiting plates 52. The first limiting part 53 is a snap-fit ​​through hole. The first inclined surface 55 is provided above the snap-fit ​​through hole and the first limiting notch 54 is provided below the snap-fit ​​through hole.

[0051] Preferred, such as Figures 1-3d As shown, in this embodiment, the elastic waterproof component 4 includes two sets of second plug holes, each set including two second pin holes for mating with a two-prong plug and three third pin holes for mating with a three-prong plug. The elastic waterproof component 4 includes an integrally formed first elastic waterproof component 41, a second elastic waterproof component 42, and a first connecting plate 43. The first connecting plate 43 connects the first elastic waterproof component 41 and the second elastic waterproof component 42. The first elastic waterproof component 41 is rectangular, with two second pin holes distributed along the length of the rectangle on both sides of the first elastic waterproof component 41. The second elastic waterproof component 42 includes three first extension plates, with the three second pin holes distributed on the three first extension plates. A first notch 44 is formed between adjacent first extension plates, and the first notch 44 is obtuse. The sum of the obtuse angles of the three first notches 44 is 360 degrees. One end of the first connecting plate 43 is connected to the middle of the second elastic waterproof component 42 along its length, and the other end is connected to one of the first extension plates of the second elastic waterproof component 42.

[0052] Of course, in other embodiments, the first elastic waterproof component 41 and the second elastic waterproof component 42 may not be integrally formed, and there may be no first connecting plate 43 between the first elastic waterproof component 41 and the second elastic waterproof component 42, which is also within the scope of protection of this application.

[0053] Preferred, such as Figure 2As shown, the back of the first cover 2 includes a first mounting groove 21. The bottom of the first mounting groove 21 is a flat structure, and the upper surface of the elastic waterproof component 4 is a flat structure. The first mounting groove 21 includes at least one set of the first plug holes. The elastic waterproof component 4 is at least partially located within the first mounting groove 21, and the upper surface of the elastic waterproof component 4 is in close contact with the bottom of the first mounting groove 21 to achieve a waterproof effect. The first mounting groove 21 on the back of the first cover 2 can both limit the elastic waterproof component 4 and enhance the sealing and waterproofing effect of the socket.

[0054] Furthermore, such as Figure 2 As shown, the structure of the first mounting groove 21 is similar to that of the elastic waterproof component 4 in this embodiment. Preferably, the side wall of the first mounting groove 21 is inclined so that the area of ​​the opening of the first mounting groove 21 near the second cover 5 is larger than the area of ​​the bottom of the first mounting groove 21, so that the elastic waterproof component 4 can be inserted into the first mounting groove 21.

[0055] In other embodiments, the socket may include a plurality of resilient waterproof components 4, each resilient waterproof component 4 including a set of second plug holes, and the socket includes a plurality of first mounting slots 21 corresponding to the plurality of resilient waterproof components 4, each first mounting slot 21 including a set of third plug holes, which is within the scope of protection of this application.

[0056] Preferred, such as Figures 3a-3d As shown, the elastic waterproof component 4 includes at least one first mounting plate 45 for fixing the second cover 5. At least one first mounting plate 45 is located at the bottom of the elastic waterproof component 4 along its thickness direction. Multiple first connecting posts are provided between the first mounting plate 45 and the first elastic waterproof component 41 and the second elastic waterproof component 42, respectively. Multiple second pin holes correspondingly penetrate the multiple first connecting posts. The first mounting plate 45, the first elastic waterproof component 41, the second elastic waterproof component 42, the first connecting plate 43, and the multiple first connecting posts are integrally formed. The elastic waterproof component 4 includes two first mounting plates 45, one located at the bottom of the first elastic waterproof component 41 and the other at the bottom of the second elastic waterproof component 42. Two first connecting posts are spaced apart between the first elastic waterproof component 41 and the first mounting plate 45, and two second pin holes penetrate the two first connecting posts respectively. Three first connecting posts are spaced apart between the second elastic waterproof component 42 and the first mounting plate 45, and three second pin holes penetrate the three first connecting posts respectively. In this embodiment, as shown... Figure 3cAs shown, the first mounting plate 45 corresponding to the second elastic waterproof component 42 is divided into an E-plate and an LN-plate, which can save production costs. By setting the first mounting plate 45 at the bottom of the first elastic waterproof component 41 and the second elastic waterproof component 42, and setting multiple first connecting posts between the first mounting plate 45 and the first elastic waterproof component 41 and the second elastic waterproof component 42, the thickness (depth) of the second pin hole of the elastic waterproof component 4 can be increased, improving the sealing performance of the second pin hole after wrapping the pin, and further improving the waterproof effect of the socket. The multiple first connecting posts, including the second pin hole, are set at intervals, which increases both the depth of the second pin hole and the elasticity of the second pin hole of the elastic waterproof component 4, thereby improving the wrapping force of the second pin hole.

[0057] Of course, in a less desirable embodiment, the depth and elasticity of the second pin hole can also be enhanced by increasing the thickness of the elastic waterproof component 4.

[0058] Preferred, such as Figure 1 Figure 3 and Figure 4 As shown, the upper surface of the second cover 5 has a central protrusion forming a first mounting portion 56. The first mounting portion 56 is a planar structure and includes at least one set of the third plug holes. The elastic waterproof component 4 is mounted on the first mounting portion 56, and at least one set of second plug holes corresponds one-to-one with at least one set of third plug holes. Specifically, the first mounting plate 45 of the elastic waterproof component 4 is mounted on the first mounting portion 56 of the second cover 5. The first mounting portion 56 can be formed by stamping, which is simple to operate and low in cost.

[0059] Preferred, such as Figure 1 As shown, the socket also includes a protective door structure, which comprises at least one protective door 6 and at least one elastic element 61. The protective door 6 is slidably disposed within the socket. The at least one protective door 6 and the at least one elastic element 61 are located between the second cover 5 and the socket assembly 3. Specifically, the elastic element 61 drives the protective door 6 to block the socket assembly 3 between the third plug hole and the socket assembly 3. This prevents single-pole insertion and small objects from contacting the socket, thus preventing electric shock accidents and improving the socket's safety. The elastic element 61 may be, but is not limited to, a compression spring, a spring, or a tension spring.

[0060] Of course, in embodiments where the second cover 5 is not provided inside the socket, the protective door 6 covers the space between the second plug hole of the elastic waterproof component 4 and the socket assembly 3, which is also within the scope of protection of this application.

[0061] Furthermore, such as Figure 1As shown, the upper surface of the protective door 6 is flat. Under the action of the elastic member 61, the upper surface of the protective door 6 is tightly fitted to the back of the second cover 5, which has a good dustproof effect when the socket is not in use.

[0062] Preferred, such as Figure 1 As shown, the protective door 6 slides back and forth between a first position and a second position. The elastic element 61 drives the protective door 6 to slide from the second position to the first position. The protective door 6 blocks the corresponding socket assembly 3 and the plug hole (the second plug hole or the third plug hole). When the protective door 6 is subjected to external force, it overcomes the elastic force of the elastic element 61 and is driven to the second position. The protective door 6 is misaligned with the plug hole, allowing the plug to be inserted into the plug hole. In this embodiment, the protective door 6 blocks the corresponding socket assembly 3 and the third plug hole.

[0063] Preferred, such as Figure 1 and Figure 5 As shown, the socket also includes a waterproof ring 51, which is installed between the second cover 5 and the socket base 1 along the thickness direction of the socket. One side of the waterproof ring 51 is tightly fitted against the back of the second cover 5, surrounding at least one set of third plug holes on the second cover 5, and the other side is tightly fitted against the internal structure of the socket base 1, surrounding at least one set of socket sleeve assemblies 3. The waterproof ring 51 creates a waterproof space between the at least one set of third plug holes and the at least one set of socket sleeve assemblies 3. Since the protective door 6 in the prior art does not have a waterproof function, water can easily flow into the socket from the connection between the protective door structure and the socket base. Therefore, the waterproof ring can prevent water from flowing into the socket from the side, causing a short circuit in the socket sleeve assembly 3 and creating a safety hazard. Figure 5 A schematic diagram of the structure of the waterproof ring 51 in an embodiment of this application is shown.

[0064] Preferably, as shown in Figure 7. Figure 9a and Figure 9b As shown, the protective door structure includes a protective door base 7, and at least one of the protective doors 6 and / or at least one of the elastic elements 61 are disposed on the protective door base 7, wherein, Figure 9a and Figure 9b These are structural diagrams of the front and back of the protective door base 7.

[0065] Furthermore, such as Figure 4 and Figure 11As shown, the middle part of the socket base 1 includes a second mounting groove for installing the protective door base 7. The side wall of the second mounting groove includes an annular protrusion 12 with the same shape as the waterproof ring 51. Multiple second limiting notches 13 are provided on the outer side of the annular protrusion 12. The waterproof ring 51 is located on the annular protrusion 12. After the socket base 1 and the second cover 5 are installed, the limiting plate 52 is stuck in the second limiting notch 13. The back of the second cover 5 and the annular protrusion 12 clamp the waterproof ring 51, limiting the movement of the waterproof ring 51. Since the second cover 5 and the annular protrusion 12 clamp the waterproof ring 51, a closed space is formed inside the socket base 1, protecting the socket sleeve assembly 3 and preventing rainwater from entering the interior of the socket base 1. This design further enhances the waterproof effect of this application.

[0066] Furthermore, such as Figure 5 and Figure 11 As shown, in this embodiment of the application, the waterproof ring 51 and the annular protrusion 12 are rectangular structures with the same structure. Of course, in other embodiments, the waterproof ring 51 can also be circular or other irregular rings, which are all within the protection scope of this application.

[0067] Furthermore, such as Figure 9b and Figure 11 As shown, the second mounting groove of the socket base 1 includes four first protrusions 16, and the protective door base 7 includes four second notches 74. The four first protrusions 16 are correspondingly locked in the four second notches 74, limiting the movement of the protective door base 7.

[0068] Preferred, such as Figure 6a , Figure 6b , Figure 8a and Figure 8b As shown, the protective door 6 includes a first protective door 62, which is used to cooperate with the N-pole and L-pole pins of the plug, blocking the L-pole pin hole and the N-pole pin hole. The first protective door 62 includes a first through hole 621, and a first extension 622 or two first extensions 622 spaced apart are provided at the end away from the first through hole 621. The first extension 622 extends along the length of the first protective door 62. When a single pole of the first protective door 62 is inserted, one end of the first protective door 62 swings, and the first extension 622 of the first protective door 62 contacts the limiting structure inside the socket, preventing the first protective door 62 from being misaligned with the plug hole. Figure 6a and Figure 6b This is a schematic diagram of the front and back structures of one embodiment of the first protective door 62; Figure 8a and Figure 8b This is a schematic diagram of the front and back of another embodiment of the first protective door 62.

[0069] Furthermore, the first through hole 621 provides sliding space for the first protective door 62. When the first protective door 62 is in the first position, the first through hole 621 is hidden inside the socket and misaligned with the plug hole. When the first protective door 62 is in the second position, the first through hole 621 corresponds to a pin hole. One pin can be connected to the socket sleeve through the first through hole 621. Another pin can be connected to the socket sleeve through one side of a first extension 622, or through the two first extensions 622.

[0070] Furthermore, such as Figure 11 As shown, a first barrier 14 is provided on the socket base 1. The first barrier 14 extends into the first through hole 621 and limits the movement of the first protective door 62, so that the displacement of the first protective door 62 between the first position and the second position is less than the width of the first through hole 621.

[0071] Preferred, such as Figure 6a , Figure 6b , Figure 8a and Figure 8b As shown, the first extension 622 is provided with a first limiting structure on two or one side opposite to the thickness direction of the first protective door 62. The socket is provided with a second limiting structure that cooperates with the first limiting structure to limit the movement. When the first protective door 62 is tilted by force, causing the first limiting structure and the second limiting structure to limit the movement, the first protective door 62 is prevented from moving from the first position to the second position.

[0072] Furthermore, such as Figure 6a , Figure 6b , Figure 8a and Figure 8b As shown, the first limiting structure can be a groove structure, and the second limiting structure can be a boss structure; or, the second limiting structure can be a boss structure, and the second limiting structure can be a groove structure.

[0073] Furthermore, such as Figure 4 and Figure 9a As shown, the protective door base 7 is provided with the second limiting structure, and / or the second cover 5 is provided with the second limiting structure.

[0074] Furthermore, such as Figure 6a , Figure 6b , Figures 8a-9bAs shown, the first protective door 62 includes two parallel and spaced first extensions 622, and a third notch 623 is formed between the two first extensions 622. The third notch 623 includes a first side, and a second sidewall is provided inside the socket opposite to the first side. When the first protective door 62 is in the first position, the second sidewall is located inside the third notch 623, the first side and the second sidewall abut against each other, and the third notch 623 is misaligned with the third plug hole. When the first protective door 62 is in the second position, the first side and the second sidewall are spaced apart, and the third notch 623 corresponds to one of the third pin holes.

[0075] Furthermore, such as Figure 9a and Figure 9b As shown, avoidance areas 624 are provided on both sides of the second sidewall. When the first protective door 62 is in the first position, the two first extensions 622 are respectively located in the two avoidance areas 624. The avoidance area 624 is provided with the second limiting structure.

[0076] Preferred, such as Figure 6a , Figure 6b , Figures 8a-9b As shown, the first protective door 62 has first sliding shafts 625 on both sides, and the socket has two first sliding rails 626 that cooperate with the first sliding shafts 625. The first sliding rail 626 includes a vertical guide section and an inclined guide section. The guide section and the guide section are bent and connected, and the included angle between them is an obtuse angle. When the first protective door 62 is in the first position, it is located inside the guide section and away from the guide section, preferably at the end of the guide section away from the guide section. When the first protective door 62 is in the second position, it is located inside the guide section and away from the guide section, preferably at the end of the guide section away from the guide section. In this embodiment, the first protective door 62 can first move vertically along the guide section, and then move inclinedly along the guide section, with displacement in both the vertical and horizontal directions. This allows the elastic member 61 to drive the first protective door 62 to move vertically along the guide section to block the plug hole when the socket is not in use, providing a better dustproof effect.

[0077] like Figure 1 and Figure 9bAs shown, when both ends of the first protective door 62 are subjected to force simultaneously, the first protective door 62 first slides along the guide section of the first slide rail 626, and the first protective door 62 generates displacement in the vertical direction. Then, the first protective door 62 slides along the guide section, changing the sliding direction. At this time, the first protective door 62 generates displacement in both the vertical and horizontal directions. The displacement generated in the horizontal direction causes the first protective door 62 to be offset from the third plug hole. When one end of the first protective door 62 is subjected to force, the first protective door 62 can rotate around the first sliding shaft 625, or while the first protective door 62 rotates around the first sliding shaft 625, the first sliding shaft 625 undergoes partial displacement in the guide section of the first slide rail 626, but will not move to the guide section of the first slide rail 626.

[0078] In this embodiment, by setting a first extension 622 and a clearance area 624, when the first protective door 62 moves vertically along the guide section, the first extension 622 is located in the clearance area 624 and also moves vertically along the clearance area 624. When the first protective door 62 moves tilted along the guide section, the first extension 622 moves vertically along the clearance area 624 and moves away from the clearance area 624. That is, the first extension 622 cooperates with the clearance area 624, and the first sliding shaft 625 and the first sliding rail 626 of the first protective door 62 cooperate to play a guiding role, making the sliding of the first protective door 62 more stable and reliable. When the first protective door 62 is in the second position, the first extension 622 is at least partially located within the clearance area 624.

[0079] Preferred, such as Figure 1 , Figure 7a and Figure 7b As shown, the protective door 6 also includes a second protective door 63, which works in conjunction with the ground pin of the three-prong plug to block the E-pole pin hole. When the second protective door 63 is in the first position, it blocks the ground pin hole of the third plug hole and the clamping arm of the socket assembly 3. When the second protective door 63 slides from the first position to the second position under the pushing force of the ground pin, the second protective door 63 is misaligned with the ground pin hole, allowing the ground pin to insert into the socket assembly 3. The second protective door 63 is used to improve the safety of the socket, prevent accidental electric shock, foreign object insertion, or misoperation, and further reduce the risk of electric shock and short circuit. Figure 7a and Figure 7b These are structural diagrams of the front and back of the second protective door 63, respectively.

[0080] Furthermore, such as Figure 7a , Figure 7b and Figure 4As shown, the second protective door 63 has two second sliding shafts 631 on both sides.

The second sliding rails 632 are linearly inclined. The second sliding shaft 631 includes two protrusions that maintain the balance of the second protective door 63. The line connecting the two protrusions is inclined and forms an acute angle with the upper surface of the second protective door 63. The second protective door 63 slides obliquely along the second sliding rails 632 within the socket. In another embodiment, the second sliding shaft 631 includes a strip-shaped protrusion. This strip-shaped protrusion is installed within the second sliding rail 632 to keep the second protective door 63 balanced and prevent it from rotating.
