Description

Technical Field

[0001] The invention relates to the technical field of sockets, and in particular to an electric shock protection socket. Background Art

[0002] Electric shock from sockets has always been a hidden danger in household electrical safety, especially for families with children. Preventing electric shock from sockets is a problem that parents often pay attention to. There are two types of anti-electric shock sockets on the market. One type uses a complex protection circuit to achieve the anti-electric shock function, but its disadvantage is that it is expensive. The other type uses a simple spring deformation to achieve the anti-electric shock function, but its disadvantage is that it cannot effectively achieve the anti-electric shock function. Summary of the invention

[0003] The purpose of the present invention is to solve the problem of poor electric shock protection effect in the prior art and to propose an electric shock protection socket.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: An anti-electric shock socket comprises a conductive mechanism and a dislocation mechanism arranged inside a housing, wherein the conductive mechanism comprises an elastic sheet and a conductive sheet mounted on the surface of the elastic sheet; The dislocation mechanism includes a displacement component for driving the conductive sheet to slide; The dislocation mechanism also includes a fixed seat and a guide rod sliding inside the fixed seat, and a swing arm for driving the displacement component to slide is arranged at the tail end of the guide rod.

[0005] In some embodiments, there are two groups of conductive mechanisms and two groups of dislocation mechanisms, which are arranged opposite to each other inside the shell and respectively cooperate with the two metal sheets of the plug.

[0006] In some embodiments, the conductive sheet is installed on the surface of the elastic sheet through an installation mechanism, the installation mechanism includes a slot arranged on the surface of the conductive sheet, the two sides of the slot are open, the tail end of the conductive sheet is bent to provide a card plate, and the surface of the elastic sheet is provided with a card slot that matches the card plate.

[0007] In some embodiments, the displacement assembly includes a bottom plate fixed to the bottom of the shell and a slider sliding on the surface of the bottom plate, and the surface of the slider is provided with an installation groove for installing the elastic sheet.

[0008] In some embodiments, the fixed seat is an extension portion that is suspended at one end near the slider, and a sliding hole and a slideway are provided on the surface of the fixed seat. The sliding hole and the slideway are both obliquely arranged and are arranged upward toward the socket at one end near the socket. The guide rod slides in the sliding hole, and a sphere slides inside the slideway. The inner end of the guide rod abuts against the surface of the sphere. The fixed seat is provided with an opening at one end near the slider, and the opening is arranged directly below the socket.

[0009] In some embodiments, a connecting shaft is fixed to the bottom of the shell, the middle part of the swing arm rotates on the upper end of the connecting shaft, and a torsion spring is sleeved on the surface of the connecting shaft. The torsion spring is used to drive the end of the swing arm close to the guide rod to rotate toward the fixed seat.

[0010] In some embodiments, guide grooves are respectively provided at both ends of the swing arm, and both guide grooves are C-shaped. Pins are respectively fixed to the outer end of the guide rod and the upper surface of the slider, and the two pins slide inside the two guide grooves respectively.

[0011] In some embodiments, the elastic sheet is disposed obliquely and tilted toward one side of the plug near one end of the plug.

[0012] In some embodiments, a step groove is provided on the lower surface of one end of the guide rod close to the sphere, and the upper end of the inclined plate of the conductive sheet extends upward.

[0013] Compared with the prior art, the present invention provides an electric shock protection socket having the following beneficial effects.

[0014] 1. The present invention provides a dislocation mechanism. When only one socket is inserted with a foreign object, for example, the socket of the live wire is inserted with a foreign object, the conductive sheet of the neutral wire is driven to move to the bottom of the socket of the neutral wire by the guide rod and the swing arm. Since the conductive sheet of the live wire does not correspond to the socket of the live wire, it cannot electrically contact with the foreign object, thereby preventing children from accidentally inserting foreign objects into the socket and causing electric shock accidents, thereby improving the anti-electric shock effect.

[0015] 2. The present invention sets a conductive mechanism to separate the conductive sheet and the elastic sheet, so that the elastic sheet only bears the role of elastic deformation. The conductive sheet is driven to make physical contact with the plug through the elastic sheet. The elastic sheet is made of spring steel, and its elastic life is much higher than that of copper alloy. Therefore, the service life of the socket can be improved.

[0016] Other advantages, objectives and features of the present invention will be described in part in the following description; and in part, will be apparent to those skilled in the art based on an examination of the following; or, may be taught from the practice of the present invention.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-11, an anti-electric shock socket, including a conductive mechanism and a dislocation mechanism arranged inside a shell 1, the conductive mechanism and the dislocation mechanism each having two groups, and are relatively arranged inside the shell 1, respectively cooperating with two metal sheets of a plug 13, two sockets for plugging the plug 13 are arranged on the upper surface of the shell 1, the conductive mechanism includes an elastic sheet 3 and a conductive sheet 2 installed on the surface of the elastic sheet 3, an insert plate is arranged at the end of the elastic sheet 3 away from the slider 502, the conductive sheet 2 is installed on the surface of the elastic sheet 3 through an installation mechanism, the installation mechanism includes a slot 401 arranged on the surface of the conductive sheet 2, both sides of the slot 401 are open, a card plate 402 is arranged at the tail end of the conductive sheet 2, a card slot 403 is opened on the surface of the elastic sheet 3, an inclined plate is arranged at the front end of the conductive sheet 2, a connector 11 for welding a wire is arranged on the side of the conductive sheet 2 away from the plug 13, the connector 11 is arranged at the bending of the inclined plate and the conductive sheet 2, the elastic sheet 3 is arranged obliquely, and the end close to the plug 13 is inclined toward the side of the plug 13, and the elastic sheet 3 remains vertical to the bottom of the shell, reference Figure 6 The elastic sheet 3 is made of spring steel, and the conductive sheet 2 is made of copper alloy.

[0031] It is understandable that, in the conductive structure of the existing socket, the conductive copper sheet has to bear both material deformation and conductive function, and the conductive copper sheet is in line contact with the plug, with large resistance, and is prone to heat during the conductive process. After long-term use, it is easy to deform, which enlarges the gap between the two conductive copper sheets, causing the plug 13 to no longer contact the conductive copper sheet or to have poor contact with the conductive copper sheet after insertion, making the socket unable to work properly. Therefore, the conductive sheet 2 and the elastic sheet 3 are separated, so that the elastic sheet 3 only bears the role of elastic deformation, and the conductive sheet 2 is driven to physically contact with the plug 13 through the elastic sheet 3. The elastic sheet 3 is made of spring steel, and its elastic life is much higher than that of copper alloy. Therefore, the plug 13 can be improved. The service life of the socket is extended. The conductive sheet 2 is inserted into the plug surface of the elastic sheet 3 through the slot 401, and the card board 402 is made to correspond to the position of the slot 401, so that the card board 402 is inserted into the card slot 403, thereby limiting the position of the conductive sheet 2. By setting the elastic sheet 3 at an angle, when the elastic sheet 3 drives the conductive sheet 2 to slide onto the surface of the plug 13, the conductive sheet 2 and the plug 13 are squeezed by the plug 13 to make them parallel and fit each other, so that the conductive sheet 2 and the plug 13 are in parallel contact, achieving the purpose of surface contact, increasing the contact area, and improving the conductive effect. At the same time, the elastic force generated by the elastic sheet 3 always pushes the conductive sheet 2 to be close to the surface of the plug 13 to prevent poor contact.

[0032] Specifically, the dislocation mechanism includes a displacement component 5 for driving the conductive sheet 2 to slide, the displacement component 5 includes a base plate 501 fixed to the bottom of the shell 1 and a slider 502 sliding on the surface of the base plate 501, a T-shaped groove is provided on the surface of the base plate 501, the slider 502 slides inside the T-shaped groove, a mounting groove 503 is provided on the surface of the slider 502, the mounting groove 503 is L-shaped with an opening 603 at the upper end, and the elastic sheet 3 is L-shaped and bent at one end close to the slider 502.

[0033] It is understandable that by providing the mounting groove 503 , it is convenient to plug the elastic sheet 3 into the surface of the slider 502 , and by sliding the slider 502 on the surface of the bottom plate 501 , it is convenient to drive the conductive sheet 2 closer to or away from the insertion hole.

[0034] Specifically, the dislocation mechanism also includes a fixed seat 6 and a guide rod 7 sliding inside the fixed seat 6. The tail end of the guide rod 7 is provided with a swing arm 10 for driving the slider 502 to slide on the surface of the bottom plate 501. The fixed seat 6 is close to the slider 502. The end of the extension part is L-shaped and bent upward near the slider 502. The surface of the fixed seat 6 is provided with a sliding hole 601 and a slideway 602. The sliding hole 601 and the slideway 602 are both obliquely arranged, and are arranged upward toward the plug hole near the end of the plug hole. The guide rod 7 slides in the sliding hole 601, and a ball 8 slides inside the slideway 602. The inner end of the guide rod 7 contacts the surface of the ball 8. The fixed seat 6 is close to the slider 502. The end is provided with an opening 603, and the opening 603 is arranged directly below the plug hole. A connecting shaft 9 is rotated in the middle of the swing arm 10. The connecting shaft 9 is fixed to the bottom of the shell 1. A torsion spring is sleeved on the surface of the connecting shaft 9. The torsion spring is used to drive the end of the swing arm 10 close to the guide rod 7 to rotate toward the fixed seat 6.

[0035] It can be understood that, in the initial state, the guide rod 7 pushes the ball 8 to contact the bottom of the socket to block the socket. At the same time, the conductive sheet 2 and the socket remain in a misaligned state. When the two plugs 13 are inserted from the socket into the opening 603 at the same time, the neutral wire plug 13 pushes the ball 8 and the guide rod 7 to slide toward the swing arm 10, thereby driving the swing arm 10 to rotate. Under the principle of leverage, the end of the swing arm 10 close to the slider 502 pushes the conductive sheet 2 of the live wire to contact the live wire plug 13, and the live wire plug 13 causes the other swing arm 10 to rotate, so that The conductive sheet 2 of the neutral wire is driven to contact the neutral wire plug 13 to form a current loop. When only one socket is inserted with a foreign object, for example, the socket of the live wire is inserted with a foreign object, the conductive sheet 2 of the neutral wire is driven to move to the bottom of the socket of the neutral wire through the guide rod 7 and the swing arm 10. Since the conductive sheet 2 of the live wire does not correspond to the socket of the live wire, it cannot electrically contact the foreign object, thereby preventing children from accidentally inserting foreign objects into the socket and causing electric shock accidents. By setting a torsion spring, the swing arm 10 and the guide rod 7 are automatically driven to reset when the plug 13 is pulled out.

[0036] Specifically, guide grooves 1001 are respectively opened at both ends of the swing arm 10, and the guide grooves 1001 are C-shaped. Pins are fixed to the outer end of the guide rod 7 and the upper surface of the slider 502, respectively. The two pins slide inside the two guide grooves 1001 respectively. A pressure plate 1002 is fixed to one end of the swing arm 10 close to the slider 502. The pressure plate 1002 is fan-shaped and always blocks the upper end of the installation groove 503 as the swing arm 10 rotates.

[0037] It is understandable that by providing the guide groove 1001 and the pin, it is convenient to keep both ends of the swing arm 10 connected with the guide rod 7 and the slider 502 at all times, and by providing the pressure plate 1002, it is prevented that the elastic sheet 3 falls off from the installation groove 503.

[0038] Specifically, a step groove 701 is provided on the lower surface of one end of the guide rod 7 close to the sphere 8 , the upper end of the inclined plate of the conductive sheet 2 extends upward, and the diameter of the guide rod 7 is smaller than the diameter of the sphere 8 .

[0039] Understandably, reference Fig.11 When a foreign object is inserted into one of the sockets, such as the socket of the live wire, the conductive sheet 2 of the neutral wire is driven to move to the bottom of the socket of the neutral wire through the guide rod 7 and the swing arm 10. At this time, the upper end of the inclined plate of the conductive sheet 2 passes over the ball 8 and moves into the slideway 602. When a foreign object wants to be inserted into the socket of the neutral wire again, since the inclined plate is in the slideway 602, the ball 8 cannot slide down through the slideway 602, so that the foreign object cannot be inserted into the socket of the neutral wire, avoiding the formation of a current loop caused by the insertion of foreign objects into the two sockets one after another. In case of an electrical accident, only when the two sockets are inserted with the plugs 13 at the same time, the inclined plate cannot block the ball 8, so that the two conductive sheets 2 are in contact with the two plugs 13 at the same time to form a current loop, thereby achieving the purpose of power supply. By setting the step groove 701, the inclined plate can be avoided, so that the inclined plate has enough height to block the ball 8, and the extended part of the fixed seat 6 is bent upward to facilitate blocking the ball 8. When the inclined plate passes over the ball 8, the inclined plate pushes the ball 8 to float, so that the inclined plate passes over the ball 8 smoothly.

[0040] Specifically, a pressing rebounder 12 is fixed inside the shell 1 , and the pressing rebounder 12 is arranged between the two insertion holes. A through hole is opened on the upper surface of the shell 1 for the upper end of the pressing rebounder 12 to extend out of the upper surface of the shell 1 .

[0041] It is understandable that when the plug 13 is pulled out from the socket, for the socket set on the wall, the force of pulling out the plug 13 transmits the force to the socket through the plug 13 and also transmits the force to the fixing screws. After long-term use, the socket and the wall will become loose, or fall off the wall. For the commonly used tow rope socket, when pulling out the plug 13, two hands must be used to exert force in opposite directions at the same time, and it is impossible to operate with one hand, which is very inconvenient. By adopting the pressing rebounder 12, when it is necessary to pull out the plug 13, the plug 13 is pressed downward, so that the plug 13 drives the upper end of the pressing rebounder 12 to be compressed inward, the internal limiting structure is released, and the plug 13 is ejected by the rebound force of the spring, so as to achieve the purpose of one-handed operation, and also to avoid the phenomenon of loosening of the socket caused by pulling out the socket with force.

[0042] In the present invention, when the plug 13 is normally inserted, the neutral wire plug 13 pushes the ball 8 and the guide rod 7 to slide in the direction of the swing arm 10, thereby driving the swing arm 10 to rotate. Under the principle of leverage, the guide groove 1001 on the surface of the swing arm 10 rotates in cooperation with the pin shaft, so that the end of the swing arm 10 close to the slider 502 pushes the conductive sheet 2 of the live wire to contact the live wire plug 13, and the live wire plug 13 rotates the other swing arm 10, thereby driving the conductive sheet 2 of the neutral wire to contact the neutral wire plug 13, forming a current loop. When a child inserts a foreign object into a socket, for example, a foreign object is inserted into the socket of the live wire, the conductive sheet 2 of the neutral wire is driven to move to the neutral wire through the guide rod 7 and the swing arm 10. The conductive sheet 2 of the live wire is below the socket, and since it does not correspond to the live wire socket, it cannot electrically contact with foreign objects, preventing children from accidentally inserting foreign objects into the socket and causing electric shock accidents. If a child wants to insert another foreign object into another socket, the conductive sheet 2 of the neutral wire moves to below the socket of the neutral wire. At this time, the upper end of the inclined plate of the conductive sheet 2 passes over the sphere 8 and moves into the slide 602. When a foreign object wants to be inserted into the socket of the neutral wire again, since the inclined plate is in the slide 602, the sphere 8 cannot slide downward through the slide 602, so that the foreign object cannot be inserted into the socket of the neutral wire, avoiding electric shock accidents caused by the formation of a current loop due to the insertion of foreign objects into the two sockets one after another.
