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. 14a, when the plug blade is not inserted into the receptacle, the plug blade is in the initial state, and 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 the initial position herein), and even if there is a large vibration outside, the plug blade will not be separated from the initial position, and the erroneous contact will not occur; as shown in fig. 14b, 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. 14c, 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 and lowermost ends (referred to as the 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 the plug blades are not erroneously disconnected. 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 safe waterproof socket, and the principle of circuit on-off is as follows: 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 safe waterproof socket also has an electric shock prevention 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 addition, the live wire jack 105 and the zero line jack 106 on the insulating part 1 of the safe waterproof socket are mutually isolated and arranged inside the insulating part 1, the live wire bottom connecting piece 3 and the zero line bottom connecting piece 7 are both positioned outside the insulating part 1, the live wire inserting piece 2 and the live wire bottom connecting piece 3 are fixedly connected through a screw 31 and form static seal, the zero line inserting piece 6 and the zero line bottom connecting piece 7 are fixedly connected through the screw 31 and form static seal, so that water cannot enter the socket from the live wire jack 105 and the zero line jack 106, and the upper cover 108 and the first waterproof silica gel pad 29 are used for preventing water from entering the socket from the periphery of the socket and avoiding the short circuit of the live wire leading-in piece 5 and the zero line leading-in piece 9 inside the socket; the live wire insertion piece 2, the live wire lead-in piece 5, the zero line insertion piece 6 and the zero line lead-in piece 9 realize the conduction and the disconnection of a circuit through a non-contact type driving reset structure, have high reliability and long service life, realize isolated driving and have no contact wear; when the plug is not plugged in, the live wire insertion piece 2 and the zero wire insertion piece 6 are not electrified, and at the moment, even if water enters the live wire insertion hole 105 and the zero wire insertion hole 106, the live wire insertion piece 2 and the zero wire insertion piece 6 cannot be in short circuit; when the plug is inserted, the live wire insertion sheet 2 and the zero wire insertion sheet 6 start to be electrified, and even if the live wire insertion hole 105 and the zero wire insertion hole 106 are filled with water, the live wire insertion hole 105 and the zero wire insertion hole 106 are isolated from each other, direct short circuit cannot be caused, and therefore the waterproof effect is better.
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 waterproof socket further includes a housing 26 and a bottom case 27, and the live wire bottom connecting piece 3, the live wire lead-in piece 5, the neutral wire bottom connecting piece 7 and the neutral wire lead-in piece 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. 13, 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. 16, the live line left floating member 21 and the live line right floating member 22 can also be connected into a whole through an intermediate connecting member, and cannot move independently, which is also feasible, but the application scenarios can be reduced.
As shown in fig. 17 to 19, the three-pin socket unit in the safe waterproof socket is a schematic diagram, the action principle and the circuit principle are the same as those of the two-pin socket unit, and the difference is that the socket further comprises a ground wire insert 28 and a ground wire bottom connecting piece 32, the insulating member 1 is provided with a ground wire jack 107, the ground wire jack 107 is isolated from a live wire jack 105 and a null wire jack 106, the bottom of the ground wire jack 107 is provided with a screw hole, and the ground wire insert 28 and the ground wire bottom connecting piece 32 are fixedly connected through a screw to form a static seal. The ground wire jack is also provided with a waterproof structure to prevent water from flowing in from the ground wire jack.
In the utility model, if the contact points of the live wire insertion sheet and the zero line insertion sheet with the plug are arranged at the positions which are as close to the bottom as possible, about 1/3 of the plug, the plug with the insulating inclusion body arranged at the root of the contact pin of the plug (such as hong Kong and European standard plugs) can realize underwater plugging operation, because in the process of inserting the plug, the live wire insertion sheet and the zero line insertion sheet start to be electrified after the first waterproof silica gel pad contacts the insulating inclusion body; when the plug is pulled out, the live wire insertion piece and the zero line insertion piece are powered off firstly, and then the insulating wrapping body is separated from the first waterproof silica gel pad, so that the spark of a contact point in the plugging process can be prevented from splashing outwards, and the occurrence of electric fire is prevented.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
