Description

Technical Field

[0001] The present invention relates to a safety component in the field of connecting an electrical appliance with a power source, and a safety protection device for a power socket. Background Art

[0002] In our daily life, power sockets are used everywhere, but existing sockets have certain unsafe factors, which bring potential safety hazards to our lives, such as electric shock caused by accidental operation, poor contact, short circuit caused by water, etc.

[0003] Electric shock due to accidental operation: Most cases of electric shock due to accidental operation are caused by young children. We know that children like to make holes, so the black holes on the sockets will mislead curious children and easily lead to danger. For this reason, most of the sockets sold on the market have been improved, that is, safety doors are added on the basis of the original sockets, but the safety doors are installed under the socket shell, and most of them are made of black material. In this way, the black holes on the sockets are more obvious, which will only increase the attraction to young children.

[0004] Poor contact: The existing sockets will have poor contact after being used for a long time. This is because of the shape of the power electrode clamp inside the existing socket. The existing electrode clamp is to bend the two sides of the copper sheet at right angles to clamp the plug. We know that the elasticity of the copper sheet is related to the processing shape. After bending at right angles for a long time, it is easy for the elastic fatigue resistance of the copper sheet to decrease. After the plug is plugged in and out many times, the copper sheet cannot return to its original state. Finally, the power electrode clamp of the socket and the clamping force on the plug become looser and looser, and finally poor contact occurs, which brings hidden dangers to fire.

[0005] Short circuit when exposed to water: In order to achieve the purpose of waterproofing the socket, many sockets now have a waterproof cover on the socket. Such a waterproof cover can play a certain role in splashing water, but it has no effect when it encounters the humidity of the rainy season or when it is used in the bathroom or kitchen with water vapor. The sockets in the bathroom and kitchen still have great safety hazards, and the use of sockets in the south during the rainy season has more serious safety hazards. Summary of the invention

[0006] The purpose of the present invention is to provide a safety protection device for a power socket to overcome the defects and shortcomings of the existing sockets.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is to provide a safety protection device for a power socket, hereinafter referred to as a socket. The socket includes: a housing, a baffle, an irregular gear, a gear positioning shaft and an arc-shaped power electrode clamp.

[0008] The appearance of the socket shell can be similar to that of the existing socket, except that the socket of the original socket is blocked by a plug baffle of similar size. From the inside, the socket hole is tightly blocked from the inside to the outside by a plug baffle like a plug under the elastic force of the elastic element. There are also irregular gears, gear positioning shafts and power electrode clamps in the shell; the reason why the irregular gear is named this way is related to its appearance. From the side, it looks like a comma, with several teeth on the comma circle, and the tail of the comma is an arc surface corresponding to the arc surface of the slide rail under the other plug baffle, which is used to control the rotation of the other plug baffle. The teeth on the irregular gear are connected to the gears on the plug baffle, and the power of rotation is also driven by the gears on the plug baffle, but the direction of rotation is opposite to that of the plug baffle, and the irregular gear is positioned by the gear rotation shaft. Only when the plug is inserted, the gear on the plug baffle drives the irregular gear to rotate and the tail of the irregular gear shifts, and the plug can push the baffle open, insert the socket to connect with the power electrode clamp, and turn on the power.

[0009] The following explains this socket in combination with the commonly used two-hole socket and three-hole socket.

[0010] The outer shell of the socket is divided into two layers, the outer shape of the socket can be designed as needed. The outer shell in the following figure adopts a circular design.

[0011] The jack of the upper shell is the same as that of the existing socket, and adopts the standard plug jack size. However, the internal structure is different from that of the existing socket in that: the upper shell has a corresponding plug baffle movable groove inside, and the corresponding plug baffle movable groove is larger than the size of the plug baffle, presenting a plug shape.

[0012] There is also a movable groove for the plug baffle inside the lower shell, and the size of the movable groove is larger than the space required for the baffle to move back and forth. Because the plug baffle is inside the lower shell and needs to rotate back and forth, the cross-section of the movable groove of the plug baffle in the lower shell is fan-shaped, and there is also space required for the power electrode clamp and space for the plug to enter and exit.

[0013] In order to achieve a better waterproof effect, the plug baffle is small at the top and large at the bottom when it is combined with the socket, that is, a plug from the inside to the outside.

[0014] The plug baffle has a rotating shaft on one side thereof for the purpose of rotating back and forth.

[0015] In order to limit the free movement of the plug baffle, an arc-shaped slide rail is designed under the baffle, and an arc surface on the slide rail corresponds to the tail of the irregular gear.

[0016] The plug baffle has an appearance consistent with the shape of the plug baffle movable groove on the shell, but its size is smaller than that of the plug baffle movable groove.

[0017] The elastic element has one end connected to the plug baffle and the other end connected to the lower shell, and is the driving force for the plug baffle to rotate back and forth and reset.

[0018] The plug baffle has a gear for driving the corresponding irregular gear under the plug baffle. Note: The irregular gear on the two-hole socket baffle is located at one end of the plug baffle axis; the irregular gear on the three-hole socket baffle is located in the middle of the grounding socket baffle axis.

[0019] The irregular gear looks like a comma from the side. The gear is on the round head of the comma. There is a round hole in the center of the round head. This is the positioning hole for the irregular gear to rotate. It is mounted on the gear positioning shaft and rotates back and forth. The gear part is combined with the gear on the plug baffle, and the power for the gear rotation is provided by the gear on the plug baffle. The tail of the comma is an arc surface corresponding to an arc surface on the slide rail under another plug baffle, which is used to control the back and forth rotation of the corresponding plug baffle.

[0020] The irregular gear positioning shaft is used for positioning the irregular gear.

[0021] The arc-shaped plug contact electrode clamp has no right-angle bending design, and the elastic fatigue resistance coefficient of the copper sheet is much greater than that of the existing plug contact electrode clamp, and the plug can be firmly clamped even in long-term use.

[0022] The present invention can effectively solve the shortcomings of existing sockets through the above technical solutions, and prevent children from accidentally touching the sockets and getting electric shocks, prevent poor contact, and prevent short circuits caused by water, etc. At the same time, the socket has a simple structure, low cost, and standard components, and can be assembled by machine, saving labor, thereby achieving a beneficial technical effect.

[0075] The above technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0076] The present invention achieves the prevention of short circuit caused by water, electric shock caused by erroneous operation and poor contact in this way.

[0077] In order to show the structure of the connection between the upper and lower shells of the two-hole socket and the three-hole socket, Fig.32 It is a left side cross-sectional view of a two-hole socket from the lock hook, 2a1 is the lock hook of the upper shell, 7a6 is the positioning groove of the lock hook of the lower shell; Fig.33 It is a left side cross-sectional view of the three-hole socket from the lock hook; 2b1 is the lock hook of the upper shell, and 7b6 is the positioning groove of the lock hook of the lower shell.

[0078] In order to explain the working principle of the two-hole socket more clearly, Fig.30It is a schematic diagram of the internal structure of a two-hole socket after removing the outer shell. When the plug 1a is inserted, the plug 1a first touches the two plug baffles 3a, and the two plug baffles 3a rotate downward with the rotating shaft 3a1 as the center. The gear 3a2 on the plug baffle rotates synchronously and drives the irregular gear 5a to rotate synchronously, but the irregular gear 5a rotates in the opposite direction. The elastic element on the rotating shaft 3a1, the torsion spring 4a, also twists and deforms synchronously with the movement of the plug baffle 3a. The plug 1a passes the plug baffle 3a and is inserted into the power electrode clamp 8a, and the power is turned on. As can be seen in the figure, the power supply electrode clamp 8a is designed in an arc shape. The electrode clamp has good resilience when the plug is inserted or removed, preventing poor contact between the plug and the socket and ensuring safety. When the plug is pulled out, the elastic element on the rotating shaft 3a1 of the plug baffle 3a, the torsion spring 4a, rebounds, and the torsion force of the torsion spring 4a pushes the plug baffle 3a back to its original position. The gear 3a2 on the plug baffle will drive the irregular gear 5a to rotate back to its original position synchronously, and the plug baffle 3a designed like a plug will block the socket 2a3 again. Prevent short circuits in water to ensure safety; Note: From Figure 7 Figure 8 Fig. 9 It can be seen that the plug baffle 3a is a plug-shaped design, which is small at the top and large at the bottom.

[0079] After the plug 1a is pulled out, the socket 2a3 on the socket has been filled by the plug baffle 3a, and there is no visible socket 2a3 on the socket. Children will no longer be curious about and play with the socket, and they are away from danger, ensuring safety.

[0080] In order to prevent children from accidentally poking the socket with a metal rod or a screwdriver, the irregular gears 5a and 5b shown in the figure are another safety feature specially designed for this purpose.

[0081] Taking a two-hole socket as an example, we will explain again how the irregular gear 5a prevents children from accidentally moving it: From the above explanation, we know that there is a gear 3a2 on the plug baffle that is connected to the gear on the irregular gear. As long as the plug baffle 3a rotates, the irregular gear will rotate synchronously. Fig.30 It can be seen that the arc surface 5a2 at the tail of the irregular gear corresponds to an arc surface 3a3 on the slide rail below the right plug baffle, but a gap is maintained. This is because if a child accidentally inserts a hard object into the right jack 2a3, the hard object will drive the plug baffle 3a to rotate downward, and the plug baffle 3a will rotate a distance, that is, the gap between 3a3 and 5a2. It will be blocked by the arc surface 5a2 at the tail of the opposite irregular gear 5a and cannot continue to rotate. Similarly, when a child accidentally inserts a hard object into the left jack 2a3, it will also be blocked by the arc surface 5a2 at the tail of the right irregular gear 5a and cannot be inserted.

[0082] from Fig.30As can be seen in the figure, the rotation of the plug baffles 3a in the left and right plug holes 2a3 will be restricted by the irregular gear tail 5a2. If the left and right plug baffles 3a want to rotate, the irregular gear tail 5a2 must be moved away for a distance so that the two arc surfaces 3a3 and 5b2 no longer correspond. However, the movement of the tail 5a2 of each irregular gear 5a must be driven by the gear 3a2 on the plug baffle 3a. That is, a gap must be reserved between the arc surface 3a3 on the lower rail of each plug baffle 3a and the tail 5a2 of the irregular gear 5a. The size of this gap can ensure that each plug baffle 3a can rotate freely for a distance without restriction.

[0083] According to the above explanation, only when the left and right jacks 2a3 are plugged with the plug 1a at the same time, the two plug baffles 3a are driven by the plug 1a, the two plug baffles 3a rotate, the gears 3a2 on the two plug baffles 3a respectively drive the irregular gears 5a below to rotate, and the arc surface 5a2 at the tail of the two irregular gears is separated from an arc surface 3a3 on the slide rail below the two plug baffles 3a and no longer corresponds. That is, the plug 1a passes the plug baffle 3a and is smoothly inserted into the socket.

[0084] Fig.31 This is a left-side cross-sectional view of a three-hole socket. Its working principle is similar to that of a two-hole socket. The difference is that among the three plug baffles 3b, only the grounding plug baffle 3b has a gear 3b2, while the other two plug baffles 3b do not have gears. There is also only one irregular gear 5b in the three-hole socket, which is placed in the grounding socket 2b3, below the grounding plug baffle 3b. The irregular gear 5b is similar to the irregular gear 5a in the two-hole socket when viewed from the side, and is different when viewed from top, bottom, and in three dimensions. Fig.13 , Fig.14 , Fig.15 It can be seen that it looks like an elongated combination of the irregular gear 5a in the two-hole socket, and has two arc surfaces 5b2 at its tail, which respectively correspond to the arc surfaces 3b3 on the slide rails below the other two plug baffles 3b to control the rotation of the other two plug baffles.

[0085] Its working principle is: when only the grounding socket 2b3 has a plug 1b inserted, the grounding plug baffle 3b drives the irregular gear 5b to reverse, and the tail 5b2 of the irregular gear moves away and no longer corresponds to the arc surface 3b3 on the slide rail under the plug baffle in the other two sockets 2b3. The slide rails under the other two plug baffles lose their obstruction, and the plug 1b smoothly passes the plug baffle 3b and is inserted into the socket. If there is no plug 1b inserted in the grounding socket 2b3, the irregular gear 5b in the socket is not driven by the gear 3b2 on the plug baffle 3b, and it remains motionless. The arc surface 3b3 on the slide rail under the other two plug baffles 3b in the socket is blocked by the two arc surfaces 5b2 at the tail of the irregular gear respectively. At this time, when a hard object is inserted into the other two sockets, the plug baffle 3b cannot rotate, and the hard object cannot be inserted.
