In this embodiment, the upper ends of the live line inner floating member 10 and the neutral line inner floating member 12 are provided with clamping shoulders 14. The clamping shoulder is used for being matched with a contact pin of the plug.
The action principle of the live wire inner floating piece 10 and the live wire outer floating piece 11 is as follows: as shown in fig. 11a, when the plug blade is not inserted into the socket, the plug blade is in an initial state, at this time, under the elastic force of the return spring 15, the live wire inner floating member 10 is at the uppermost end (blocked by the upper cover 108 to prevent coming off), and a suction force is formed between the live wire inner floating member 10 and the live wire outer floating member 11, so that the live wire outer floating member 11 is stably at the innermost side and the uppermost end (referred to as an initial position herein), and even if there is a large vibration outside, the plug blade cannot be separated from the initial position, and the false contact cannot occur; as shown in fig. 11b, when the plug blades are gradually inserted into the socket, the plug blades push the shoulder 14 of the floating member 10 in the live wire to move downward, the attraction force between the floating member 10 in the live wire and the floating member 11 outside the live wire is gradually changed into force balance, and then changed into repulsion force, so as to push the floating member 11 outside the live wire to move outward and downward; as shown in fig. 11c, when the plug blades are fully inserted into the receptacle, the live wire inner floating member 10 is located at the lowermost end, and the live wire outer floating member 11 is stably located at the outermost side and the lowermost end (referred to as an operating position herein), and due to the repulsive force between the live wire inner floating member 10 and the live wire outer floating member 11, even if there is a large vibration outside, the live wire inner floating member and the live wire outer floating member do not separate from the operating position, and thus, erroneous disconnection does not occur. When the plug insert is pulled out, the floating part 10 in the live wire moves upwards under the thrust of the return spring 15 to return to the initial position, and simultaneously drives the floating part 11 outside the live wire to move upwards and inwards to the initial position. The advantage of doing so, do not need very big spring restoring force just can do the upper and lower reset of very big stroke, still can add non-magnetizer (such as insulating plastics) in the middle of live wire inner floating piece 10 and live wire outer floating piece 11, can do non-contact motion and reset. The operation principle of the neutral inner float member 12 and the neutral outer float member 13 is completely identical, and the description thereof is not repeated.
The above is the action process and principle of the safety socket, and the following is the principle of circuit on-off: when the plug inserting piece is not inserted, the live wire outer floating piece 10 and the zero wire outer floating piece 11 are located at initial positions, the first metal wrapping piece 17, the second metal wrapping piece 18, the third metal wrapping piece 19 and the fourth metal wrapping piece 20 and other metal parts are all in a disconnected state, and the live wire inserting piece 2, the live wire leading-in piece 5, the zero wire inserting piece 6 and the zero wire leading-in piece 9 are also in a disconnected state, so that the live wire inserting piece 2 and the zero wire inserting piece 6 are not electrified, and basic safety protection is achieved; when the plug inserting sheet is inserted, the outer floating piece 11 of live wire and the outer floating piece 13 of zero line are in working position, the live wire inserting sheet 2 is connected with the live wire bottom connecting sheet 3 in sequence, the first metal wrapping sheet 17, the live wire side connecting sheet 4, the fourth metal wrapping sheet 20 is electrically connected with the live wire leading-in sheet 5, the zero line inserting sheet 6 is connected with the zero line bottom connecting sheet 7 in sequence, the third metal wrapping sheet 19, the zero line side connecting sheet 8, the second metal wrapping sheet 18 is electrically connected with the zero line leading-in sheet 9, the live wire inserting sheet 2 and the zero line inserting sheet 6 are electrified, and the normal socket conducting effect is achieved.
When only the floating part 10 in the live wire is pressed down, the floating part 12 in the zero wire is not pressed down, at the moment, the live wire insertion piece 2 is not electrified because the connecting piece 4 on the side surface of the live wire is not electrically connected with the fourth metal wrapping piece 20, and the fourth metal wrapping piece 20 is not electrically connected with the live wire leading-in piece 5, and the connecting piece 7 on the bottom of the zero wire is not electrically connected with the third metal wrapping piece 19, and the third metal wrapping piece 19 is not electrically connected with the connecting piece 8 on the side surface of the zero wire, so the zero wire insertion piece 6 is not electrified. When only the floating part 12 in the zero line is pressed down, the floating part 10 in the live line is not pressed down, at the moment, the connecting sheet 8 on the side surface of the zero line is not electrically connected with the second metal wrapping sheet 18, and the second metal wrapping sheet 18 is not electrically connected with the zero line leading-in sheet 9, so the zero line inserting sheet 6 is not electrified, and the connecting sheet 3 on the bottom of the live line is not electrically connected with the first metal wrapping sheet 17, and the first metal wrapping sheet 17 is not electrically connected with the connecting sheet 4 on the side surface of the live line, so the live line inserting sheet 2 is not electrified. Only when the floating piece 10 in the live wire and the floating piece 12 in the zero line are all pressed down, the socket has the conductive function, and the safety protection is upgraded and is safer.
The safety socket also has an anti-electric-shock function, only after the plug is inserted into the socket, the live wire insertion piece and the zero line insertion piece in the socket start to be electrified, and when the plug is not inserted into the socket, the live wire insertion piece and the zero line insertion piece in the socket are not electrified; and still carried out safe upgrading, only when live wire contact pin and zero line contact pin all insert, live wire inserted sheet and zero line inserted sheet just can be electrified, so safer.
In this embodiment, the live wire inner floating member 10 and the neutral wire inner floating member 12 are located inside the insulating member 1, and the live wire outer floating member 11 and the neutral wire outer floating member 13 are located outside the insulating member 1, so that non-contact movement and reset are formed, and the live wire inner floating member and the neutral wire outer floating member can be used as a base structure of a waterproof socket. Of course, the components are arranged together in the insulating part, and the movement and the electric connection relation of the components are not influenced.
In this embodiment, as shown in fig. 6, the fire wire bottom connecting piece 3 is further bent upwards to form a vertical first contact piece 23, and when the fire wire outer floating piece 11 is pushed downwards and outwards, the first contact piece 23 is electrically connected with the side surface of the first metal covering piece 17, so that the fire wire bottom connecting piece 3 and the first metal covering piece 17 have two contact points, and the reliability can be improved by larger current; the connecting piece 7 at the bottom of the zero line is also bent upwards to form a vertical second contact piece 24, and when the floating piece 13 outside the zero line is pushed downwards and outwards, the second contact piece 24 is electrically connected with the side surface of the third metal wrapping piece 19, so that the connecting piece 7 at the bottom of the zero line and the third metal wrapping piece 19 are provided with two contact points, and the reliability can be improved through larger current.
In this embodiment, as shown in fig. 7, silver plating layers are further disposed on the outer side surfaces and the bottom surfaces of the first sheet metal covering 17, the second sheet metal covering 18, the third sheet metal covering 19, and the fourth sheet metal covering 20, and riveted silver-plated contacts 25 are disposed at the contact conductive portions of the live wire side connection piece 4 and the neutral wire side connection piece 8, so as to pass a larger current and improve reliability.
In this embodiment, as shown in fig. 1 and 2, the safety socket further includes a housing 26 and a bottom case 27, and the live bottom connecting pad 3, the live lead-in pad 5, the neutral bottom connecting pad 7 and the neutral lead-in pad 9 are all fixed on the bottom case 27.
Of course, it is also feasible that the live wire bottom connecting piece, the live wire lead-in piece, the zero wire bottom connecting piece and the zero wire lead-in piece are fixed on the circuit board firstly and then fixed on the bottom shell.
In this embodiment, as shown in fig. 10, it is also significant that the live line inner floating member includes a live line left floating member 21 and a live line right floating member 22 which are independent of each other, and the neutral line inner floating member includes a neutral line left floating member and a neutral line right floating member (not shown) which are independent of each other. Because of the separation, the position between the external force and the object can be adjusted according to the size of the object applying the external force, the structure can be suitable for more scenes, the accidental insertion contact of foreign objects can be prevented, not all external objects can push the structure, and only the object conforming to the shape, such as a standard plug, can be used. In addition, if the left live wire floating piece 21 and the right live wire floating piece 22 move independently, the action of the outer live wire floating piece 11 cannot be caused, because only half of the magnetic force cannot push the outer live wire floating piece 11, only the two pieces move simultaneously, the outer live wire floating piece 11 can be actuated, the misoperation of the two pieces can be prevented, and the switch is triggered by mistake. The reason why the first metal covering piece 17 and the first metal covering piece 18 on the live wire outer floating piece 11 are not made into separate structures for independent movement is mainly to ensure the consistency of actions, and of course, the first metal covering piece can be made into separate structures on occasions with different functions. The zero line left floating piece and the zero line right floating piece are the same in principle and are not repeated here.
As shown in fig. 13, the live line left floating member 21 and the live line right floating member 22 may also be connected into a whole through an intermediate connecting member, and cannot move independently, which is also feasible, but the application scenarios may be reduced.
