Description

Explosion-proof, waterproof and non-electric safety socket

The present invention provides an explosion-proof, waterproof and non-electric safety socket, in particular a male push switch and a micro switch. When a plug is inserted, it can be pressed against the male push switch, and the micro switch can only conduct electricity after the micro switch is activated, and has a waterproof setting. And it has an independent groove in the lower half to achieve the effect of waterproof and explosion-proof.

Press, the socket is usually installed in the wall plug or extension cord of the building, which is mainly used to connect to the mains, and the power supply plug is inserted for use, so as to supply electricity to the electrical appliances; sockets and plugs are available in various countries in the world. , Sizes and types are different, and each country has its own government standards.

The socket is equipped with conductive shrapnel inside to clamp and conduct electricity to the copper contact of the electrical appliance plug. Most sockets are designed to only accept the corresponding plug in order to reduce the risk of electric shock. However, there are still many doubts about its safety. , Here are detailed below one by one:

1. If a young child in the house accidentally inserts a metal object into the socket and touches the conductive shrapnel, it has the risk of electric shock.

2. In case of flooding, the power of the socket will still be conducted, although the farther away from the socket, the weaker the electric field, so generally speaking, only a slight electric shock will occur, but it still has a certain degree of danger. If the distance from the socket is Closer, if there is a metal conductor in the area with a strong electric field at this time, it will have a strong touch inductance, which will increase its risk; not only that, the water after flooding will invade and oxidize the circuit in the socket. Cause unpredictable danger due to short-circuit failure.

3. Generally speaking, when the plug is inserted into the socket, or when the electrical appliance is started, a slight spark will be generated between the plug and the socket, and if the application environment is a place such as a factory with flammable or flammable gas, it may cause a gas explosion. Dangerous.

It is known that every plug, regardless of any style or shape, has an insulator covering the two conductive conductive copper sheets, so the insulator will have a larger frame to cover it, which can be used safely by the human hand.

The conventional art also provides a shrapnel arrangement, which coats the copper plate of the socket with a nano-coating to isolate it from the effect of waterproof and electric shock. But this design is not perfect. When the plug is often used, it will fall off and disappear under friction and impact. Even if the socket is not used frequently, the nano-coating will gradually disappear over time. When the nano-coating disappears and no longer has any waterproof effect, there is no way or method to know, and the user will misbelieve it. It has a waterproof function, which will produce a greater risk of electric shock, so the waterproof safety design is not perfect.

The conventional knowledge also discloses a safety socket that requires the two conductive copper pieces to be protruding from the plug, and the thickness and width must conform to the design specifications of other sockets to start the power supply. This design has great disadvantages, as everyone has a string of multiple sockets. The key, but only one can be opened.

In a house, there must be a lot of wall sockets on the wall. In the modern world, there are tens of thousands of household electrical products, with different sizes of plugs. When you want to use the power supply, there are not many household appliances plugs. When plugging into this standard design socket , There must be very few home appliances that can be energized.

The standard design socket that can be energized and used by the power supply will pick up the plug, which will cause a lot of trouble for the user. Therefore, it is certain that few people will install this kind of standard socket, and it is not safe to use this kind of standard socket.

Based on the above description and settings, it is obvious that the present invention mainly has the following advantages and effects, which are described in detail as follows:

1. The invention can be applied to industrial and household extension cords and wall plugs. When the convex push switch is not pressed, the first conductor and the second conductor, and the first and second guide seats, will be affected by the failure of the micro switch. When the electricity is energized, a circuit is formed. Therefore, no matter whether the metal is used to contact the first guide seat and the second guide seat from the outside, it will not cause electric shock, so it can greatly reduce the risk of electric shock caused by accidental touch by young children; the present invention requires the plug When inserted into the first guide seat and the second guide seat, the plug is provided with the flat surface of one end of the copper contact to press the convex push switch of the convex push switch, and the convex push switch touches the micro switch to make it energize. The channel is used for power supply, thereby greatly improving the safety of the present invention; in addition, the safety mechanism of the present invention is not susceptible to external forces to cause its safety to fail, and can withstand the impact test of a high-pressure water gun, so its safety is permanent and effective .

2. When the present invention is flooded, because as mentioned above, when the convex push switch is not pressed, the first conductor and the second conductor will form an open circuit with the first guide seat and the second guide seat, so it is in the water There is still no danger of electric shock.

3. The present invention is equipped with a fail-safe indicator light, which will light up when the first guide seat and the first conductor form a path, or the second guide seat and the second conductor form a path, which can indicate whether the socket is currently supplying power , So that the user can know whether the copper plate in the socket is energized. When the plug is not plugged in, if the fail-safe indicator lights up, it means that the copper plate in the socket hole has power supply. The gas explosion safety device is now available, and with the fail-safe indicator light, users can use it with peace of mind.

4. The present invention is between the cover body, the base body and the lower half of the independent groove, and between the convex pressing switch, the fail-safe indicator lamp and the perforation and through hole of the cover body connected with the light-emitting unit, the convex pressing switch and the pressing hole Each room is equipped with a single or multiple waterproof components to prevent water from entering the socket from the outside to protect the internal components and circuits, so as to achieve an excellent waterproof effect.

5. Even if the present invention is applied to a place with flammable gas, the inside of the socket is formed through the arrangement of the lower half of the independent groove, and the seal is not in contact with the outside air. If sparks are generated by the micro switch inside the socket, it will not ignite the outside Because the combustible gas is in a sealed state, the device of the present invention can also achieve the effect of explosion-proof.

Regarding the technical design methods of our inventors, several preferred embodiments are described in detail below in conjunction with the drawings, so as to provide an in-depth understanding and approval of the present invention.

Please refer to Figures 1 to 8, which is the first embodiment of the present invention, which is applied to an extension cord. The present invention is an explosion-proof, waterproof, non-electric safety socket, which includes:

A base body 1 is provided with a first conductor 11 and a second conductor 12, and at least one conductive group 2 is connected between the first conductor 11 and the second conductor 12; the base body 1 is provided with an opening 13 and A corresponding cover 3 is provided at the opening 13;

The conductive group 2 respectively includes a first guide seat 21 and a second guide seat 22; between the first guide seat 21 and the first conductor 11, and the second guide seat 22 and the second conductor A micro switch 4 is respectively provided between 12; the conductive group 2 is respectively provided with a convex pressing switch 5, and an elastic unit 51 is arranged between the bottom end of the convex pressing switch 5 and the base 1;

The cover 3 is provided with an insertion hole 31 corresponding to the first guide seat 21 and the second guide seat 22, and a pressing hole 32 corresponding to the convex pressing switch 5, each of the pressing holes 32 is similar to Corresponding to the socket 31, the convex pressing switch 5 is pressed by the elastic unit 51, so that the top end of the convex pressing switch 5 protrudes from the pressing hole 32; and the convex pressing switch 5 is pressed by force At this time, the elastic unit 51 is elastically pressed, and the micro switch 4 is pressed to turn on the micro switch 4, so that the first conductor 11 is electrically conductive to the corresponding first guide seat 21, and the second conductor 12 is electrically conductive to the corresponding The second guide seat 22.

And as shown in Figure 4, as far as the waterproof configuration of the first guide seat 21 and the second guide seat 22 is concerned, the seat body 1 is located at a position corresponding to the first guide seat 21 and the second guide seat 22. The lower half of the independent groove 14 is provided, and the lower half of the independent groove 14 is insulated. In one embodiment, the lower half of the independent groove 14 can be formed by potting, but it is only an example for illustration. It is not limited to this, and the first guide seat 21 and the second guide seat 22 are respectively arranged in the lower half of the independent groove 14; in order to achieve the effect of waterproofing, the bottom of the cover 3 The end is further provided with an upper half of the independent groove 33 corresponding to the lower half of the independent groove 14, and it can be known that the cover 3 is provided with a socket 31 corresponding to the first guide seat 21 and the second guide seat 22 Therefore, the upper independent groove 33 is provided at a position corresponding to each insertion hole 31; preferably, the upper independent groove 33 is provided on the inner wall surface of the lower independent groove 14, so that in case of flooding, Even if water enters the outside, the water system first fills the lower half of the independent tank 14 and it is extremely difficult to flow back between the upper half of the independent tank 33 and the lower half of the independent tank 14; A waterproof gasket 331 is sheathed outside the upper independent groove 33, and the lower independent groove 14 presses the waterproof gasket 331 against the wall surface of the cover 3, so as to prevent the water from flowing back into the interior of the present invention.

Regarding the configuration of each convex push switch 5, as shown in Figures 5 and 6, it can be provided with a positioning base 15 on the base 1, and the positioning base 15 is provided with an elastic unit 51 and placed on the positioning base. The side edge of 15 is vertically cut with a limit slot 151 corresponding to the convex push switch 5, which can limit the convex push switch 5 to only move vertically, and cannot move in the rotation direction, so that the convex push switch 5 is not caused by rotational displacement The micro switch 4 cannot be pressed reliably; and the top end of the convex pressing switch 5 is further covered with a waterproof cover 52. The side edge of the waterproof cover 52 is provided with a set of connecting parts 521, and the cover 3 is in the pressing hole 32. A combination portion 321 corresponding to the combination portion 521 is further provided there to prevent water from entering the interior of the present invention through the pressing hole 32.

Specifically, there is a positioning arm 53 on both sides of the convex pressing switch 5, and the positioning arm 53 is located in the limiting groove 151 to achieve the effect of preventing rotation, and the end of the positioning arm 53 is provided with a straight arm 54. The end of the upright arm 54 has a corresponding latching slot 55 that is engaged with the micro switch 4, so that the convex push switch 5 can drive and act on the micro switch 4; and the micro switch 4 can be an existing push-type circuit switch. A path can be formed when pressed, and an open circuit can be formed when not pressed. This is a conventional technology, so I won’t repeat it here; therefore, as for the operation of the convex pressing switch 5, as mentioned above, in the initial state, it is As shown in Figure 5, because the convex push switch 5 is not pressed at this time, the micro switch 4 is open. Therefore, the first guide seat 21 and the second guide seat 22 are not energized at this time, therefore, Even if the metal is used to insert the first guide seat 21 and the second guide seat 22, or when flooded, it will not cause electric shock, so as to achieve excellent safety, and will not fail due to long-term use or external impact者; And between the convex push switch 5 and the cover 3 can be additionally provided with a waterproof collar 56 to further achieve the effect of waterproofing.

And as shown in Figures 1 and 6, when the plug 6 of an electrical appliance is inserted into the first guide base 21 and the second guide base 22, one end plane of the plug 6 provided with copper sheet contacts will press against the convex push switch 5. Therefore, it is preferable that the position of the convex pressing switch 5 and the pressing hole 32 should lean against the socket 31. In addition, the convex pressing switch 5 should only slightly protrude from the cover 3, so that the copper sheet of the plug 6 can be connected. It’s better to insert at least 97% of the points into the convex pressing switch 5 to be able to press the convex pressing switch 5. As mentioned above, when the convex pressing switch 5 is pressed, the elastic unit 51 will be compressed and the upright arm 54 The micro switch 4 will be driven and pressed, so that the micro switch 4 will form a path, so the first conductor 11 will be conductive to the corresponding first guide base 21, and the second conductor 12 will be conductive to the corresponding second guide base 22. It can be powered to drive electrical appliances.

As mentioned above, in addition to the effects of preventing electricity and water, if it is used in an environment with a flammable gas, if it is set to insert at least 97% of the copper contact point, it can be pressed. The convex push switch 5, at this time, because the copper sheet of the plug 6 has contacted the first guide seat 21 and the second guide seat 22 to form a large area of contact, no spark will be generated. It is also commonly known as a bright spot. Because the lower half of the independent groove 14 is provided in the closed space inside the socket, it is not in contact with the outside air, so it will not cause air explosion, so the present invention can also achieve the effect of explosion-proof.

In order for the user to know clearly whether the first conductor 11 and the second conductor 12 of the present invention are over-charged, a power indicator light 7 can be provided, which is connected to the first conductor 11 and the second conductor 12. The power indicator light 7 can be illuminated when the power is over, indicating that it is currently in normal operation, and the cover 3 is provided with a through hole 34 corresponding to the power indicator light 7, and the power indicator light 7 and the through hole 34 A waterproof element 71 is provided between the holes 34 to prevent water from entering the interior of the present invention through the through holes 34; and as far as the configuration of the power indicator light 7 is concerned, it can have a stepped surface and be inserted from the outside of the cover 3, and The waterproof element 71 is inserted into the power indicator light 7 from the inner side of the cover 3, and the power indicator light 7 is positioned by screws or other fixing methods, so as to achieve the waterproof effect. However, the configuration is only an example and is not a limitation.

Regarding the arrangement of the lines 9 of the first conductor 11 and the second conductor 12, they are respectively connected to a conductive wire 8, and the outer edge of the conductive wire 8 is provided with a waterproof part 81; the base body 1 and the cover body 3 are provided There are recessed holes 16, 35 corresponding to the conductive wire 8, and the waterproof portion 81 is pressed against the wall of the recessed holes 16, 35; and two waterproof units are further provided between the base 1 and the cover 3 82. Through the assembly of the conductive wire 8 and the combination of the base 1 and the cover 3, the waterproof effect can be achieved; and in one embodiment, the junction of the edges of the base 1 and the cover 3, As shown in Figs. 2, 4, 5, and 6, they can be arranged in a stepped shape and formed with corresponding concave-convex features to accommodate and press the waterproof unit 82 to achieve an excellent waterproof effect.

In another embodiment, in order to make the user clearly know whether the first guide seat 21 and the second guide seat 22 of the present invention are energized, in a preferred embodiment, as shown in Figures 2, 3, 7, and 8. As shown, the conductive group 2 further includes a fail-safe indicator light 23, the cover 3 is provided with a perforation 36 corresponding to the fail-safe indicator light 23, and the fail-safe indicator light 23 is provided with two light-emitting elements 24, 24 ', the light-emitting elements 24, 24' are respectively provided with two wires 241, 241', one of the light-emitting elements 24, one of the wires 241 is connected to the first conductor 11, and the other of the wires 241' Is connected between the corresponding second guide base 22 and the micro switch 4; and one of the wires 241 of the corresponding other light-emitting element 24' is connected to the second conductor 12, and the other The wire 241' is connected between the corresponding first guide base 21 and the micro switch 4; thereby, when the micro switch 4 located at one end of the first guide base 21 is energized, the corresponding light-emitting element 24, 24' will light up. In the same way, when the micro switch 4 located at one end of the second guide base 22 is energized, the corresponding light-emitting elements 24, 24' will also light up, so the user can use the fail-safe indicator 23 Whether it emits light or not, it is then judged whether the first guide seat 21 and the second guide seat 22 are energized. When the micro switch 4 loses its power-off function due to long-term use, it will remain energized, so that the protrusion is not pressed. When the switch is pressed, the fail-safe indicator 23 is still on. At this time, it means that the first guide seat 21 or the second guide seat 22 is still energized. At this time, the user can know the damage, and choose whether to repair and replace it. Maintain safety, or continue to use it directly as a conventional extension cord.

Regarding the waterproof setting of the fail-safe indicator light 23, in one embodiment, a waterproof member 231 is further provided between the fail-safe indicator light 23 and the perforation 36, and the installation method can be the same as that of the power indicator light 7. In order to achieve the equivalent waterproof effect, water cannot enter the interior of the present invention through any holes, so it is obvious that the present invention does have good waterproof and explosion-proof effects, and has excellent safety.

The present invention is provided with a convex push switch 5, the part of the extension cord, in order to prevent accidentally touching the convex push switch 5, so in the convex push switch 5, the fail-safe indicator 23 is designed to be higher than the convex push switch 5. There are many to prevent accidentally touching the convex push switch 5. Because there is some distance from the convex push switch 5, it does not affect the use of general sockets.

The protection scope of the present invention is the convex pressing switch 5. The design position is set up close to the two holes of the jack 31. The convex pressing switch 5 is arranged on the outer side of the insulator frame of each plug 6. The plug 6 is inserted into the socket to a depth of 100% Ninety-seventh of the time, it is pressed. The present invention designs a convex pressing switch 5 to activate the micro switch 4 inside the socket, and then it is used for power transmission and power supply.

Any type of plug 6 has an insulator frame, and when the plug 6 is used, the convex push switch 5 provided in the present invention can be pressed, so the present invention can be applied to any plug 6 without picking the plug 6.

Please continue to refer to Figures 9 to 16, which is the second embodiment of the present invention. The difference from the first embodiment is that this embodiment is applied to wall plugs. Since the mains system is equipped with line 9, it is necessary to The line 9 is inserted into the present invention to conduct power supply to the first conductor 11 and the second conductor 12. Therefore, the conductive wire 8 is not configured in this embodiment, but is tied to the base body 1 corresponding to the first conductor 11 And the second conductor 12, there are two positioning slots 17 respectively.
