Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a wall socket. Background Technology

[0002] Wall sockets are becoming increasingly widely used in daily life. When used with plugs, they can be used to connect or disconnect electrical equipment, thus serving the purpose of connecting the power supply.

[0003] In existing wall sockets, water often flows into the back of the socket during use, entering through the base wiring hole on the back and causing a short circuit inside, affecting user experience. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waterproof wall socket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This application provides a wall socket, including a mounting shell and a base. The base includes a base housing, which includes a top wall and a bottom wall opposite to each other, two side walls opposite to each other, and a rear wall. The rear wall is opposite to the mounting shell. A base receiving cavity is formed inside the base housing. At least two terminals and at least two sockets are provided in the base receiving cavity. The rear wall of the base housing protrudes away from the mounting shell to form a terminal receiving groove protrusion. The terminals are installed in the terminal receiving groove protrusion. A first water inlet groove is provided on the base housing. The first water inlet groove is located at the connection between the top wall and / or the rear wall or the top wall and the rear wall. The first water inlet groove is located above the terminal receiving groove protrusion and is configured to block water flowing into the terminal receiving groove.

[0007] In one possible implementation, the bottom wall of the base housing is provided with a drainage outlet.

[0008] In one possible implementation, the first water inlet channel is strip-shaped and parallel to the upper edge of the mounting shell, with one side of the first water inlet channel parallel to the rear wall and the other side integrally formed with the rear wall.

[0009] In one possible implementation, the two ends of the first water inlet channel protrude from both sides of the protrusion of the terminal receiving groove.

[0010] In one possible implementation, at least one end of the first water channel is bent and connected to a second water channel, which is used to channel water to the ground.

[0011] In one possible implementation, the second water channel extends toward the ground and is distributed on at least one side of the terminal receiving groove protrusion.

[0012] In one possible implementation, the base housing has a square structure, and the drainage outlets are respectively opened at two corners of the bottom wall of the base housing.

[0013] In one possible implementation, the terminal receiving groove protrusion includes a wire hole and a fastening screw hole, the wire hole being located away from the mounting housing and the fastening screw hole facing the first water inlet groove.

[0014] In one possible implementation, at least one protective door structure is provided inside the base receiving cavity, and the wall socket is provided with a first through hole corresponding to the socket;

[0015] The protective door structure includes a resilient seal, a protective door, and a resilient element. The seal is at least partially located between the first through hole and the protective door and is in close contact with the mounting surface where the first through hole is provided. The seal has a second through hole corresponding to the first through hole for the pin structure to pass through.

[0016] The protective door can move between a first position and a second position. The elastic element is connected to the protective door and drives the protective door to move from the second position to the first position. The protective door can move from the second position to the first position when subjected to force.

[0017] When the protective door is in the first position, the elastic element drives the protective door to fit tightly against the sealing element and blocks the second through hole. The force applied by the elastic element to the protective door has a component force opposite to the direction of the pin structure being inserted into the first through hole.

[0018] When the protective door is in the second position, the protective door is offset from the second through hole, and the protective door releases its obstruction of the second through hole.

[0019] In one possible implementation, the seal is an "I"-shaped structure, including a first plate, a second plate, and a connecting post connecting the first plate and the second plate. The connecting post is embedded in a first through hole. The first plate and the second plate are located on both sides of the first through hole, and the second plate is in close contact with the mounting surface and located between the first through hole and the protective door. Alternatively, the seal is a plate-shaped structure that fits tightly with the mounting surface and is located entirely between the first through hole and the protective door.

[0020] In one possible implementation, the protective door slides along a first track between a first position and a second position. The first track is inclined relative to the direction in which the pin structure is inserted into the first through hole, so that when the protective door is in the first position, the elastic element drives the protective door to fit tightly against the sealing element.

[0021] In one possible implementation, the protective door is rotatably disposed inside the wall socket, with the rotation axis of the protective door perpendicular to the direction in which the latch structure is inserted into the first through hole. When the protective door is in the first position, the elastic element drives the protective door to rotate and tightly fit with the sealing element.

[0022] In one possible implementation, the upper side of the protective door corresponding to the first through hole is a plane.

[0023] In one possible implementation, the mounting housing is provided with an E-pole pin hole, and the seal of the protective door structure cooperates with the protective door to seal the E-pole pin hole, with the second through hole of the seal corresponding to the E-pole pin hole.

[0024] Compared with the prior art, this application provides a first water channel above the protrusion of the terminal receiving groove, which can be used to collect water flowing towards the protrusion of the terminal receiving groove and guide the water to the ground. This can prevent water from entering the base receiving cavity from the protrusion of the terminal receiving groove, which could cause a short circuit and affect normal use.

[0025] Furthermore, a drain outlet is provided at the bottom of the base housing to drain water that has entered the base housing cavity.

[0026] Furthermore, the fastening screw holes face the first water inlet, making it easier for operators to view the wiring from above. The first water inlet can also shield and protect the fastening screw holes.

[0027] Furthermore, the protective door structure is provided with an elastic sealing element between the first through hole and the protective door or inside the first through hole. When the protective door is in the first position, the force applied to the protective door by the elastic element has a component force opposite to the direction of the insertion of the pin structure into the first through hole. The elastic sealing element makes the protective door fit tightly with the sealing element, sealing the first through hole and preventing water from entering the socket. Attached Figure Description

Detailed Implementation

[0037] 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.

[0038] like Figures 1-5 As shown, the wall socket includes a base 1 and a mounting shell 2. The mounting shell 2 covers the base 1. The base 1 includes a base housing 11, which includes a top wall and a bottom wall opposite to each other, two side walls opposite to each other, and a rear wall opposite to the mounting shell 2. The top wall, bottom wall, rear wall, and two side walls surround the base housing 11. A base receiving cavity 12 is formed inside the base housing 11. At least two terminals and at least two sockets are provided inside the base receiving cavity 12. The at least two terminals are connected to the at least two sockets. The mounting shell 2 is provided with at least one set of socket holes 3. The set of socket holes 3 includes at least two pin holes. The at least two pin holes correspond to the at least two sockets. One of the at least two pin holes is used to connect to the L-pole pin on the plug, and the other pin hole is used to connect to the N-pole pin on the plug. One of the at least two terminals is connected to the L-pole cable, and the other terminal is connected to the N-pole cable. Between the mounting shell 2 and the base shell 11, a pressure plate, a protective door, and / or a mounting bracket may be provided as needed. Preferably, the top and bottom walls are flat and perpendicular to the rear wall, the two side walls are relatively parallel and perpendicular to the rear wall, and the two side walls are perpendicular to the top and bottom walls.

[0039] The rear wall of the base housing 11 protrudes away from the mounting housing 2. A terminal receiving groove is formed on the front of the base housing 11 relative to the mounting housing 2, and a terminal receiving groove protrusion 4 is formed on the back. The terminal is installed in the terminal receiving groove. After the wall socket is installed on the wall, the top wall is located above the bottom wall.

[0040] The base housing 11 is provided with a first water channel 13, which is located at the top wall and / or the rear wall or the connection between the top wall and the rear wall. The first water channel 13 is located above the protrusion 4 of the terminal receiving groove and is used to collect water flowing towards the protrusion 4 of the terminal receiving groove and guide the water to the ground. It is used to block water flowing towards the terminal receiving groove and can prevent water from entering the base receiving cavity 12 from the protrusion 4 of the terminal receiving groove, which would cause a short circuit and affect normal use.

[0041] Furthermore, the first water inlet trough 13 is provided with a connection between the rear wall and the top wall.

[0042] The wall socket is installed on the wall, with the bottom of the mounting shell 2 and the bottom wall of the base shell 11 located near the ground, and the top of the mounting shell 2 and the top wall of the base shell 11 located away from the ground. The side of the base shell 11 opposite to the mounting shell 2 is the rear wall of the base shell 11.

[0043] Preferably, the bottom wall of the base housing 11 is provided with a drain outlet 14 for draining water that enters the base receiving cavity 12.

[0044] Preferably, the first water inlet trough 13 is strip-shaped and parallel to the upper edge of the mounting shell 2. Water flowing into the first water inlet trough 13 can be evenly distributed inside the first water inlet trough 13. Water is drawn out from both ends of the first water inlet trough 13. One side of the first water inlet trough 13 is parallel to the rear wall, and the other side is integrally formed with the rear wall. The bottom surface of the first water inlet trough 13 is basically parallel to the top wall of the base shell 11. The bottom surface of the first water inlet trough 13 can be a plane or an arc surface, etc.

[0045] Furthermore, it can also be tilted, allowing water to flow out from one end.

[0046] Furthermore, the two ends of the first water channel 13 protrude from both sides of the terminal receiving groove protrusion 4. This is used to allow rainwater to flow out from both sides of the terminal receiving groove protrusion 4.

[0047] Preferably, at least one end of the first water channel 13 is bent and connected to a second water channel 15. The second water channel 15 is used to guide water to the ground. The bottom surface of the second water channel 15 faces the side wall of the base housing 11. Preferably, the connection between the first water channel 13 and the second water channel 15 is arc-shaped. Setting it to arc shape can produce a better drainage effect.

[0048] Furthermore, in this embodiment, the two ends of the first water inlet trough 13 are bent and connected to the second water inlet trough 15.

[0049] Furthermore, the second water inlet trough 15 extends toward the ground and is distributed on at least one side of the terminal receiving groove protrusion 4.

[0050] Furthermore, the second water channel 15 is formed by partially bending at least one end of the first water channel 13 toward the ground, and does not extend to at least one side of the terminal receiving groove protrusion 4.

[0051] In a preferred embodiment, the first water inlet trough 13 and the second water inlet trough 15 are arranged vertically.

[0052] Furthermore, such as Figures 2-5 As shown, the base housing 11 in this embodiment has a square structure, and the drainage outlets 14 are respectively provided at the two corners of the bottom wall of the base 1, which has a better drainage effect.

[0053] Furthermore, the drain outlet 14 is located at the junction of the bottom wall and the rear wall.

[0054] Preferably, the terminal receiving groove protrusion 4 includes a wire hole 41 and a fastening screw hole 42. The wire hole 41 is located in the direction away from the mounting shell 2, and the fastening screw hole 42 faces the first water inlet 13, which makes it convenient for the operator to view the wiring from above. The first water inlet 13 can also shield and protect the fastening screw hole 42.

[0055] Preferred, such as Figure 6-11As shown, at least one protective door structure 6 is provided inside the base receiving cavity 12. The wall socket has a first through hole 71 corresponding to the socket sleeve. The protective door structure 6 includes an elastic seal 62, a protective door 63, and an elastic member 64. The seal 62 is at least partially located between the first through hole 71 and the protective door 63 and is in close contact with the mounting surface where the first through hole 71 is provided. The seal 62 has a second through hole 72 corresponding to the first through hole 71 for the pin structure 65 to pass through. The protective door 63 can be in a first position. The elastic element 64, connected to the protective door 63, drives the protective door 63 to move from the second position to the first position. The protective door 63, under force, can move from the second position to the first position. When the protective door 63 is in the first position, the elastic element 64 drives the protective door 63 to fit tightly against the sealing element 62, blocking the second through hole 72. When the protective door 63 is in the second position, the protective door 63 is offset from the second through hole 72, and the protective door 63 releases its obstruction of the second through hole 72. Specifically, when the protective door 63 is in the first position, the elastic sealing element 62 ensures a tight fit between the protective door 63 and the sealing element 62, sealing the first through hole 71 and preventing water from entering the socket. Thus, the waterproof socket of this embodiment can be used in outdoor or indoor bathroom areas without the need for a protective cover to prevent water or other water from entering the socket. Of course, a protective cover can also be installed.

[0056] In one embodiment, the protective door structure 6 includes a bracket 61, an elastic sealing element 62, a protective door 63, and an elastic element 64. The protective door structure 6 cooperates with the latch structure 65. In this embodiment, the bracket 61 is provided with a first through hole 71 for the latch structure 65 to pass through, and the sealing element 62 is provided with a second through hole 72 corresponding to the first through hole 71. The inner side of the bracket 61 facing the protective door 63 is the mounting surface. After the sealing element 62 is installed with the bracket 61, the first through hole 71 and the second through hole 72 are positioned to allow the latch structure 65 to pass through. The sealing element 62 is at least partially located between the first through hole 71 and the protective door 63, and may also be partially embedded inside the first through hole 71. The sealing element 62 is elastic in whole and is made of silicone, rubber, etc.

[0057] In another embodiment, the protective door structure 6 does not include the bracket 61. The base housing 11 is provided with an installation structure for mounting the seal 62, the protective door 63 and the elastic member 64. The pin hole on the mounting shell 2 is the first through hole 71. The inner side of the mounting shell 2 facing the protective door is the mounting surface. The seal 62 is mounted on the mounting shell 2.

[0058] In another embodiment, the wall socket further includes a cover plate located between the mounting housing 2 and the base housing 11. A seal 62 is mounted on the cover plate, and the cover plate has the first through hole 71. The inner side of the cover plate facing the protective door 63 is the mounting surface.

[0059] The protective door 63 is movable between a first position and a second position. An elastic element 64, connected to the protective door 63, drives the protective door 63 to move from the second position to the first position. The protective door 63 can also move from the second position to the first position under force. The second position is the position of the protective door 63 after the latch structure 65 is inserted into the protective door structure 6, and the first position is the position of the protective door 63 after the latch structure 65 is removed from the protective door structure 6. Figure 7 A schematic diagram of the structure when the protective door 63 is in the first position is shown. Figure 8 A schematic diagram of the structure when the protective door 63 is in the second position is shown;

[0060] When the protective door 63 is in the first position, the elastic member 64 drives the protective door 63 to fit tightly against the sealing member 62 and blocks the second through hole 72. The force applied by the elastic member 64 to the protective door 63 has a component force opposite to the direction of the insertion of the pin structure 65 into the first through hole 71. The elastic member 64 can be a spring, compression spring, torsion spring, etc.

[0061] When the protective door 63 is in the second position, the protective door 63 is offset from the second through hole 72, and the protective door 63 releases its obstruction of the second through hole 72.

[0062] Furthermore, such as Figure 6-8 As shown, in the first embodiment, the sealing element 62 can be an "I"-shaped structure, including a first plate, a second plate, and a connecting post connecting the first plate and the second plate. The connecting post is embedded in the first through hole 71. The first plate and the second plate are respectively located on both sides of the first through hole 71. The second plate is close to the mounting surface and located between the first through hole 71 and the protective door 63. In this embodiment, the size of the second through hole 72 on the sealing element 62 is smaller than that of the first through hole 71, and can be consistent with the cross-sectional size of the pin structure. Of course, since the sealing element 62 is elastic, the size of the second through hole 72 can also be smaller than the cross-section of the pin structure, so that the pin structure can be clamped and fixed, and the sealing element 62 can achieve a better waterproof effect.

[0063] Furthermore, such as Figure 9-11As shown, in the second embodiment, the sealing element 62 is a flat plate structure, tightly fitting the mounting surface and entirely located between the first through hole 71 and the protective door 63, that is, tightly fitting the inner side of the bracket 61, cover plate, or mounting shell 2, located between the protective door 63 and the first through hole 71. The fixing method can be using waterproof adhesive. The second through hole 72 on the sealing element 62 can be the same size as the first through hole 71, facilitating the insertion of the pin structure. Figure 10 A schematic diagram of the structure when the protective door 63 is in the first position is shown. Figure 11 A schematic diagram of the structure when the protective door 63 is in the second position is shown.

[0064] In one embodiment, the protective door 63 slides along the first slide rail 612 between a first position and a second position. The first slide rail 612 is inclined relative to the direction in which the pin structure 65 inserts into the first through hole 71, so that when the protective door 63 is in the first position, the elastic member 64 drives the protective door 63 to fit tightly against the sealing member 62. The bracket 61 has inclined first slide rails 612 on both sides or on the base housing 11. The first slide rail 612 is a track groove or track hole. The protective door 63 has protrusions 611 on both sides, and the two protrusions 611 are installed in the first slide rail 612 and slide inclinedly along the first slide rail 612. Thus, the force exerted by the elastic member 64 on the protective door 63, guided by the first slide rail 612, has a component force opposite to the direction in which the pin structure inserts into the first through hole 71, ensuring that the protective door 63 fits tightly against the sealing member 2.

[0065] Preferably, in order to ensure better balance after the protective door 63 is installed on the bracket 61 or the base housing 11, the protective door 63, the bracket 61, or the base housing 11 is provided with two protrusions 611 at intervals.

[0066] Preferably, the protective door 63 has a first protrusion 641 on the side facing the elastic member 64, and the bracket 61 or the base housing 11 has a second protrusion 642 on the side facing the elastic member 64. The two ends of the elastic member 64 are fixed on the first protrusion 641 and the second protrusion 642.

[0067] Preferably, in other embodiments, the protective door 63 is rotatably disposed inside the wall socket. The protective door 63 rotates between a first position and a second position. The rotation axis of the protective door 63 is perpendicular to the direction in which the latch structure 65 is inserted into the first through hole 71. When the protective door 63 is in the first position, the elastic member 64 drives the protective door 63 to fit tightly against the sealing member 62. That is, the plane in which the protective door 63 rotates is not parallel to the plane in which the first through hole 71 is located, but perpendicular to the plane in which the first through hole 71 is located.

[0068] Specifically, mounting holes or mounting grooves are provided on both sides of the bracket 61 or inside the base housing 11, and fixed shafts are provided on the opposite sides of the protective door 63. The protective door 63 is rotatably installed in the bracket 61 or base housing 11 through the cooperation of the fixed shafts with the mounting holes or mounting grooves. An elastic element 64 is provided between the protective door 63 and the bracket 61 or base housing 11. The elastic element 64 drives the protective door 63 to rotate and fit tightly against the sealing element 62.

[0069] Furthermore, the upper side of the protective door 63 corresponding to the first through hole 71 is a plane.

[0070] Preferably, the protective door structure 6 is provided at pole E within the base receiving cavity 12, i.e., reference Figure 5 In this embodiment, the wall socket has only one protective door structure 6. The sealing element 62 and the protective door 63 of the protective door structure 6 cooperate to seal the E-pole pin hole. The second through hole 72 of the sealing element 62 corresponds to the E-pole pin hole, and the first through hole 71 is the E-pole pin hole, or the first through hole 71 corresponds to the E-pole pin hole. Of course, the protective door structure 6 can also be set for the L-pole and N-pole to produce a better waterproof effect.

The three pin holes are the L pole pin hole, N pole pin hole and E pole pin hole, respectively used to insert the first L pole pin, the first N pole pin and the ground pole pin, for connecting a three-prong plug.

[0072] Two pin holes are respectively set in two sockets in the base receiving cavity 12. The two sockets are respectively connected to two terminals in the terminal receiving groove. The two terminals are respectively connected to the L-pole cable and the N-pole cable. The two pin holes are respectively used to insert the second L-pole pin and the second N-pole pin for connecting the two-pole plug. After the three-pole plug and the two-pole plug are inserted into the wall socket, the three-pole plug and the two-pole plug are connected in parallel.

[0073] Of course, the base cavity 12 may also include two terminals for connecting two-prong plugs only, or four terminals for connecting four-prong plugs, wherein the four terminals are respectively connected to L1 pole cable, L2 pole cable, L3 pole cable and N pole cable, or include different combinations of terminals for two-prong plugs and / or three-prong plugs and / or four-prong plugs.
