Description

Technical Field

[0001] This utility model relates to connectors in the field of electrical engineering, and is a single-phase two-pole socket with a grounding socket that also allows for the insertion of a single-phase two-pole plug, implemented by using a seesaw-type balanced safety gate or a stepped rotating locking safety gate. Background Technology

[0002] Currently, in the application of known sockets, the vast majority of single-phase two-pole sockets with grounding holes cannot be directly plugged into single-phase two-pole plugs. Even with inventions such as CN112271516A and CN112260021A, there is no safety door protection scheme, which violates the standard that sockets must be equipped with safety doors. In particular, the rotation of the two holes relies on a lever-driven complex braking structure, which is very inconvenient. More importantly, the dynamic connection of the current-carrying components in the circuits of the two holes poses a risk of loose connection, which cannot meet the circuit connection standards at all, and makes it even more difficult to supervise and control the quality before mass production.

[0003] Therefore, based on its shortcomings, the application of the seesaw balance safety door has led to the innovative step-by-step lock-position safety door, filling the gap that for more than 20 years, the only safety door design has been the seesaw balance design, with no other solutions available. Summary of the Invention

[0004] This utility model features an innovative neutral and live wire socket with a rotating function, and also adds a safety door to protect the socket. It allows single-phase two-pole plugs with grounding and single-phase two-pole plugs to pass through. It also innovatively provides slots for the current-carrying components of the interlocking plugs, allowing for the close fit of single-phase two-pole plugs with grounding and single-phase two-pole plugs with neutral and live wires. It can be applied to wall sockets, floor sockets, power strips, track sockets, converters, and socket expansion plugs, etc., in all electrical engineering connectors.

[0049] The difference between the seesaw-style balanced safety door and the stepped alternating lock safety door scheme is that...

[0050] The seesaw-style balanced safety door has two guide ramps that are simultaneously presented in each of the live and neutral wire sockets, allowing the pins to drive the two guide ramps at the same time, thus forcing the safety door to move.

[0051] The seesaw-style balanced safety door includes a geometry composed of a bottom curved surface, an upper curved surface, and a side wall. The upper curved surface may also include one or more guide slopes, or the bottom end of the guide slope is connected to a plane. The geometry is used to shield single-phase two-pole sockets and single-phase two-pole sockets with grounding in a socket.

[0052] The geometry slides toward the sidewall or may also include an elastic body fixing nesting device, the elastic body fixing nesting device including at least one sidewall closed or sidewall semi-open groove.

[0053] The bottom surface of the geometry may also include bumps or slides.

[0054] The standby state of the stepped alternating locking safety door is that the first guide ramp and the first locking wall are respectively presented in each neutral and live wire socket. The pin can only drive one guide ramp, forcing the safety door to move.

[0055] The stepped rotating lock type security door includes a geometric body composed of an upper curved surface, a bottom curved surface, and a side wall, characterized in that the two holes of the corresponding live and neutral wire sockets on the upper curved surface to the bottom curved surface of the security door are located.

[0056] One type of hole has a stepped design with a first guide ramp, a second locking wall, and an AC pin through hole; the other type of hole has a stepped design with a first guide locking wall, a second guide ramp, and an AC pin through hole.

[0057] The AC pin via includes any one of four walls, three walls, two walls, or one wall.

[0058] The sliding wall of the stepped rotating locking safety door may also include an elastic body locking mechanism.

[0059] The stepped rotating locking safety door bottom curved surface, or may include at least one of the protrusions or slides designed to reduce its friction.

[0060] The stepped rotating locking safety door may be located at the AC pin through hole adjacent to either or both of the first locking wall and the second locking wall, or may also include a barrier wall.

[0061] The locking wall surface includes any one or at least two of a plane, a concave surface, and a concave-convex mating surface.

[0062] The stepped rotating locking safety door may have one or both of its first guide ramp and second guide ramp sliding to at least one of the two sides, or may include an additional locking wall.

[0063] The additional locking wall may include at least one of the additional locking walls, or may include additional blocking walls.

[0064] The seesaw-style balanced safety door and the stepped alternating lock safety door are made of any one or at least two of the following materials: plastic, crystal, glass, and ceramic.

[0065] The crystal, glass, ceramic, or may also include physical or chemical tempering.

[0066] The seesaw-type balanced safety door and the stepped alternating locking safety door are used for sockets with any one or at least two combinations of single-phase two-pole sockets and single-phase two-pole sockets with grounding.

[0067] The current-carrying component corresponds to the single-phase two-pole neutral and live wire hole slot of the current-carrying component pin plate slot. One of the shapes is the intersection extracted from the combination of single-phase two-pole and single-phase two-pole neutral or live wire pin plate shapes, which is wound into a semi-enclosed current-carrying component.

[0068] The decorative surface, panel, bottom shell, retaining plate, front panel, and back plate are connected by interlocking hooks or by nuts for fixing at least one of them.

[0069] The snap-fit ​​tray has one or two of the decorative surface, panel, snap plate, panel, and back plate, and the remaining holes corresponding to the tray sockets are plug pin through holes, including round holes, polygonal holes, or irregular holes.

[0070] The connection between the decorative surface and the panel, the panel and the back panel, the decorative surface and the panel, the panel and the back panel, and the panel and the bottom shell includes at least one of the following: bonding, ultrasonic welding, nesting, snap-fitting, and screws.

[0071] The locking wall or slot is designed so that when the safety door is driven by a single click, the safety door will deflect and get stuck in the locking wall or slot, unable to move and exposing the socket.

[0072] The safety door may also include a protrusion on the guide slope sidewall between the live and neutral wire pins of the plug after its relative displacement from the socket, i.e., the neutral and live wire pin isolation wall.

[0073] The tray with a rotating snap-fit ​​function includes: the tray wall is provided with protrusions and hooks that are snap-fitted into any corresponding embedded holes of the decorative surface, panel, card plate, or panel, limiting the tray setting range to rotate based on the insertion hole as the axis.

[0074] The tray is a rotatable geometric shape such as a columnar geometry, a combination of columnar geometry, a drum-shaped body, or a conical frustum.

[0075] The tray cannot disengage from the snap-fit ​​device when it rotates, and when it rotates to the point where the two holes are parallel, it forms a single-phase two-pole socket hole.

[0076] The rotation refers to the fact that the tray can only rotate around the insertion hole as an axis, and its end face is always parallel to the surface of the embedded shell.

[0077] The rotation of the tray is a conversion from the single-phase two-pole grounded neutral and live wire socket position to the single-phase two-pole socket position.

[0078] The rotation angle limiting device is a gear meshing, convex-concave, convex-convex or concave-concave nested device; one side is set in the tray bearing hole, and the other side is set in the tray. The tray teeth are meshed with the tray bearing hole wall and are concentric. Based on the concentric axis, the tray teeth move in the panel teeth.

[0079] The tray rotation angle limiting device also includes the meshing of the teeth on the neutral and live wire trays to achieve synchronous driving of the neutral and live wire sockets.

[0080] The reset of the rotation angle limiting device, i.e. the reset of the neutral and live wire socket, means that the neutral and live wire socket is initially based on a parallel or figure-eight shape. Under the forced insertion of a single-phase two-pole grounded plug or a single-phase two-pole plug, the tray rotates, and its hole position matches the shape of the plug pins for insertion. When the tray rotates, it presses the elastic body, causing the elastic body to generate potential energy. After the plug is pulled out, the tray rotates in the opposite direction to the initial position.

[0081] The tray has a rotating function.

[0082] The protrusions or hooks on the pallet wall are reinforced by any of the following: decorative surface and panel, panel and back panel, card plate and back panel, decorative surface and panel, or panel and back panel, limiting the pallet setting range based on the insertion hole as the axis of rotation.

[0083] Alternatively, viewed from the side, the I-shaped tray can be disassembled into two T-shaped or a combination of a T-shaped and a straight section. It can be reinforced by at least one of the following: bonding, ultrasonic welding, or snap-fitting of the decorative surface, panel, card plate, or any corresponding hole of the panel. The tray setting range is limited to rotation based on the insertion hole as the axis.

[0084] The tray may also include a rotation angle limiting device, which includes teeth on the side wall of the tray, with two tray teeth meshing and rotating synchronously until there are no teeth or no matching teeth; or, the tray may rotate to a blocking wall; or, the tray wall may have protrusions that support the decorative surface and panel, panel and back panel, card plate and back panel, decorative surface and panel, and panel and back panel within a set track, i.e., the range of rotation.

[0085] The track range set by the decorative surface and the panel, the panel and the back panel, the card plate and the back panel, the decorative surface and the panel, and the panel and the back panel; or, including the tray wall having a concave part and the decorative surface, panel, card plate, panel, and back panel having a convex part on the side wall of any corresponding hole, which interlocks with the convex part, which limits the rotation range of the concave part; or, including the elastic body potential energy driving the tray convex or concave part to limit its rotation angle.

[0086] The elastomer includes any geometric shape with elastic characteristics, particularly any or any combination of rubber, sponge, spring or sheet.

[0087] When the center of the tray is eccentric to the center of the socket, the size of the socket is equal to the standard socket position.

[0088] When the center of the tray is concentric with the center of the socket, the size of the socket is close to the standard socket position.

[0089] The inner side of the socket and the current-carrying component also include a socket protection safety door with a sliding connection.

[0090] The sliding connection is either a convex-concave nesting or a fence-like obstruction, and has a certain range of back-and-forth movement. The reset of the safety door is provided by its gravity.

[0091] The safety door serves to prevent misinsertion of a single pole.

[0092] The function of the safety door guide ramp is to drive the safety door to move horizontally under the vertical force of the plug, so as to make room for the socket channel and expose the pin slot of the current-carrying component.

[0093] The safety door also includes a deflection device protrusion, which functions to deflect the safety door and lock it into the locking groove or wall when the guide slope of the safety door is subjected to force, thereby achieving the function of preventing misinsertion.

[0094] The deflection device includes a deflection arc surface, or includes a protrusion on the arc surface or plane.

[0095] The horizontal displacement device of the safety door may also include a concave or convex part on the inner side of the panel socket or the inner side of the shell socket, which cooperates with the convex part of the deflection device of the safety door, or the convex part of the deflection device is replaced by a concave part, and also has the deflection function when the safety door is subjected to force on one side.

[0096] The connection between the spring and the safety door includes a wall, convex, concave, or convex-concave geometric shape at the corresponding position of the safety door, and a wall, convex, concave, or convex-concave geometric shape at the other end of the spring at the corresponding position of the panel, front shell, or bottom shell.

[0097] The safety door also includes a shielding wall for the live and neutral wires of the plug. The shielding wall is the protrusion of the live and neutral wires exposed before the current-carrying component is connected after the plug pins are inserted into the socket.

[0098] One or both of the panel or decorative surface are transparent or opaque: the panel or decorative surface is glass, plexiglass or metal decoration.

[0099] Alternatively, it may include transparent panels or shells to fully expose current-carrying components, or even embed lighting units to provide light sources in the dark or when pedestrians pass by, or to conceal monitoring and alarm devices.

[0100] The design of the pin insertion point of the current-carrying component not only satisfies the vertical insertion of the pin, but also the insertion when the pin is rotated 30°. The insertion is that the side wall of the pin is attached to the side wall of the current-carrying component.

[0101] The decorative surface, panel, card plate, front panel, and back panel are provided with sockets including any of the following: single-phase three-hole, single-phase five-hole, single-phase six-hole, single-phase seven-hole, single-phase eight-hole, single-phase nine-hole, single-phase ten-hole, single-phase eleven-hole, single-phase twelve-hole, single-phase thirteen-hole, single-phase fourteen-hole, single-phase fifteen-hole, single-phase sixteen-hole, single-phase seventeen-hole, single-phase eighteen-hole, single-phase nineteen-hole, single-phase twenty-hole, single-phase twenty-one-hole, single-phase twenty-two-hole, single-phase twenty-three-hole, single-phase twenty-four-hole, single-phase twenty-five-hole, single-phase twenty-six-hole, single-phase twenty-seven-hole, single-phase twenty-eight-hole, single-phase twenty-nine-hole, single-phase thirty-hole, single-phase thirty-one-hole, single-phase thirty-two-hole, single-phase thirty-three-hole, single-phase thirty-four-hole, single-phase thirty-five-hole, single-phase thirty-six-hole, single-phase thirty-seven-hole, single-phase thirty-eight-hole, single-phase thirty-nine-hole, and single-phase forty-hole sockets.

[0102] The nested elastomer serves to protect the housing when the power strip or adapter falls and the elastomer is the first part to touch the ground, or to enhance the housing's appearance and make it more eye-catching and aesthetically pleasing.

[0103] The connection between the decorative surface and the panel, the panel and the back panel, the card plate and the decorative surface, the card plate and the back panel, the panel and the decorative surface, the panel and the back panel, and the panel and the bottom shell includes at least one of the following connections: adhesive, solvent, fastener, hinge, insert, molded thread, tapped thread, pressure fit, snap fastener, riveting, welding, and fusion.

[0104] The screen display includes at least charging data display, time, timing, sound and light warnings, touch control, monitoring and camera, and remote control.

[0105] The purpose of this utility model for setting up a safety door lock position wall / slot is to lock the safety door and prevent displacement when the neutral and live wire sockets are mistakenly inserted. Therefore, the setting of multiple safety door lock position walls / slots is to meet or enhance the locking effect. In other words, theoretically only one safety door lock position wall / slot is needed to lock the live wire socket, and theoretically only two safety door lock position walls / slots are needed to lock the neutral and live wire sockets.

[0106] The shape of the faceplate of this utility model is not limited to a convex shape, and includes any geometric shape.

[0107] The rectangular shape of the socket in this utility model is only one example; it also includes circular or irregularly shaped through holes.

[0108] This utility model may also include a grounding socket with a tray that can rotate to accommodate different socket positions or for common use, thus saving the number of grounding sockets. Attached Figure Description

[0126] The rotation of the socket in this invention is achieved passively. It is achieved by forcing the plug pins into the socket or by external force to rotate the neutral and live wire socket angles. The neutral and live wire socket rotates and corrects itself to match the shape of the plug pins when inserted.

[0127] Example 1: In the initial state of this utility model, a single-phase two-pole grounded standard hole is inserted. The single-phase two-pole grounded plug is inserted, and the two prongs push against the two guide slopes 41 of the seesaw-type safety door through the neutral and live wire sockets 3 provided on the tray 31. The guide slopes deflect the thrust of the prongs, driving the safety door 4 to press the elastic reset support 8 or the potential energy generated by the gravity of the safety door, and displace together to make way for the socket 3. The prongs are then inserted into the current-carrying component prong slot 21 provided on the current-carrying component 2. After the prongs are removed, the safety door 4 returns to its original position between the socket 3 and the current-carrying component 2 by gravity or the elastic body, blocking the neutral and live wire sockets 3.

[0128] Example 2: In its initial state, this utility model is a single-phase two-pole standard hole with grounding. When a single-phase two-pole plug is inserted, the plug pins drive the neutral and live wire sockets 3 on the tray 31 to be passively rotated to the single-phase two-pole socket position. Alternatively, the user can use the plug pins to rotate the neutral and live wire sockets 3 one by one to the single-phase two-pole socket position, and then continue to insert the neutral and live wire sockets 3 towards the safety door guide slope 41. The guide slope deflects the push force of the plug pins, driving the safety door 4 to press the elastic reset support 8 or the potential energy generated by the gravity of the safety door, and displace together to make room for the socket 3. The plug pins are then inserted into the current-carrying component plug pin slot 21 on the current-carrying component 2. After the plug pins are removed, the safety door 4, through gravity or one or both of the elastic body, returns to its original position between the socket 3 and the current-carrying component 2, blocking the neutral and live wire sockets 3. The neutral and live wire sockets 3 are then in the single-phase two-pole socket position.

[0129] Example 3: When the neutral and live wire socket 3 is in the single-phase two-pole socket position, insert a single-phase two-pole grounded plug, and the neutral and live wire plug pins drive the neutral and live wire socket 3 on the tray 31 to be passively rotated to the single-phase two-pole grounded socket position. Alternatively, the user can use the plug pins to rotate the neutral and live wire socket 3 one by one to the single-phase two-pole grounded socket position, and then continue the above operation.

[0130] Example 4: Based on any one of Examples 1, 2 or 3, it also includes a socket solution without a safety door 4, which is also within the scope of this utility model.

[0131] Example 5: Based on any one of Examples 1, 2 or 3, it also includes a solution of adding a neutral and live wire pin isolation wall 47 to the safety door to prevent bare wires from being inserted into the socket.

[0132] Example 6: Based on Examples 1 to 5, it also includes an elastic body that automatically resets the tray socket to its initial state after the plug is disconnected.

[0133] Example 7: The rotation of the live and neutral wire socket trays as described in Examples 1 to 6 includes individual rotation and synchronous rotation with interlocking teeth.

[0134] Example 8: When the solutions based on Examples 1 to 7 are applied to power strips, mobile sockets, or adapter sockets, they also include an elastomer embedded in the corners to protect the casing from drops.

[0135] Example 9: The schemes based on Examples 1 to 8 also include additional functions.

[0136] Example 10: When the conductor is poked into one of the live wire or neutral wire sockets, the safety door 4 in Examples 1, 2, 3, 5, 6, 7, 8, and 9 deflects and gets stuck in the safety door lock wall / groove 48, preventing horizontal displacement, thereby ensuring the isolation between the conductor and the current-carrying component 2 and preventing electric shock.

[0137] Example 11: When using the stepped rotating locking safety door in Examples 1, 2, 3, 5, 6, 7, 8, and 9, the pin can only drive the first guide ramp in one of the sockets. The first guide ramp deflects the push force of the pin, driving the safety door to move until the first guide ramp exits, and the second locking wall appears. The same process occurs in the other socket, where the first locking wall exits, and the second guide ramp appears to take over and force the pin to move downwards, continuing to drive the safety door to move to the AC pin through hole, passing through the current-carrying component.

[0138] Example 12: When a foreign object is inserted into the insertion hole with the first guide slope, the direction of the deflection force of the guide slope causes the protective door to shift. When the foreign object slides towards the second locking wall, the deflection force disappears, the protective door stops shifting, and a reverse thrust is generated on the foreign object. The other insertion hole is replaced by the second guide slope blocking hole under the blockage of the first locking wall, ensuring the concealment of the current-carrying component.

[0139] Example 13: When a foreign object is inserted into the insertion hole of the stepped rotating locking safety door, the locking wall directly pushes against the foreign object, and the stepped rotating locking safety door does not move; the other insertion hole is still blocked by the first guide slope.

[0140] Example 14: Based on Examples 11, 12, and 13, additional locking walls are provided on both sides of the sliding trajectory of the first guide slope. When a foreign object pierces the additional locking wall, the effect of Example 13 is achieved.

[0141] Example 15: Based on Examples 11, 12, and 13, after at least one of the first and second locking walls is provided with an additional locking wall, as long as a foreign object is trapped in one of the additional locking walls, that is, if another foreign object is used to poke the first or second guide slope of the other socket, the safety door will no longer move.

[0142] Figure 11 The bottom shell can be disassembled into a bottom shell and a clip, with the bottom shell and the clip being snapped together and fixed, or the top shell and the clip being snapped together and fixed.

[0143] For example, the panel of a socket with a single-phase two-pole grounding socket and a single-phase two-pole plug can be provided with the following on one or more sides: a single-phase two-pole grounding socket, a single-phase two-pole socket, a current or signal plug terminal interface, a fluorescent mark, an electric light indicator, an electric mosquito coil heating device, a display screen, a charging device and a fixing device, a switch, a circuit control module inside the housing, a monitoring and alarm device, a rectifier transformer module, a wireless charging module, and a current and voltage control module, or the charging device fixing device can include at least one of the following: a panel bracket, a hook, a slot, a protruding nail claw, a magnetic attraction, or other additional functions. These are all optional additions to this utility model.

[0144] The via is a combined via formed by superimposing a vertical insertion hole and an insertion hole at an angle of 30°.
