Description

The present invention relates to a sheet-shaped fire extinguishing member, an electrical connection device using the sheet-shaped fire extinguishing member, a roll-shaped fire extinguishing tape for forming a sheet-shaped fire extinguishing member, and a method for forming the sheet-shaped fire extinguishing member.

Conventionally, for example, as an electrical connection device, an electric leakage prevention type outlet and an outlet cover described in Patent Document 1 have been proposed. Of the leakage prevention type outlets and outlet covers, the outlets are arranged, for example, on the wall in the house. On the other hand, the outlet cover is arranged on the above-mentioned wall at an opening formed in the central portion thereof so as to be fitted into the outlet from the outer periphery thereof.

Here, the outlet cover is made of, for example, bakelite, synthetic resin, metal, or the like, and the outlet cover plays a role of decorating the outlet and preventing noise. Further, the outlet is made of, for example, a synthetic resin, and the outlet plays a role of exhibiting electrical insulation performance.

Some electrical connection appliances having such a configuration are arranged on the wall of the kitchen in the kitchen of a house, for example. Here, when the refrigerator is arranged on the back wall of the refrigerator so as to face the above-mentioned wall with a gap from the outlet, the connection cord extending from the back wall of the refrigerator is , It is connected to the outlet with the plug. As a result, the refrigerator is powered by a commercial power source via an outlet and a connection cord to operate.

However, in the electrical connection device configured in this way, the connection / disconnection of the plug to the outlet is performed by inserting / removing the double-edged blade of the plug to both the insertion holes of the outlet. As a result, power is supplied to the refrigerator and the power is stopped.

Japanese Patent Application Laid-Open No. 2003-303641

By the way, in the above-mentioned electric connection device, once the plug of the connection cord of the refrigerator is connected to the outlet, the connection is continued for a long period of time due to the nature peculiar to the refrigerator. That is, the state of being inserted into both insertion holes of the double-edged outlet of the plug is continued for a long period of time due to the nature peculiar to the refrigerator. Further, since there is only a gap between the back wall of the refrigerator and the inner wall of the kitchen as described above, the surface of the outlet is in a position where it is difficult to clean. Therefore, dust easily adheres to the surface of the outlet.

Therefore, as described above, if the double-edged plug is inserted into both insertion holes of the outlet for a long period of time, dust adheres to the surface of the outlet. In addition, dust tends to be in a state in which an energable short-circuit state is likely to occur by absorbing moisture in the air.

If dust that is likely to cause such a short-circuited short-circuit state adheres along between the double-edged blades of the plug, the double-edged blades will be affected because the voltage of the commercial power supply is applied to the double-edged blades via the outlet. In the meantime, it will be short-circuited through the water-containing dust that adheres along the way. Due to such a short circuit, the dust ignites due to its heat generation, causing a so-called tracking phenomenon, which leads to a dangerous situation in which the outlet, the plug, and the kitchen are involved in the fire.

In such a dangerous situation, the outlet cover plays a role of decorating the outlet and preventing noise, but even if a fire occurs in the outlet, the outlet cover can be used to extinguish the fire due to the tracking phenomenon. It's useless.

To this end, it is conceivable to use the leakage prevention type outlet and the outlet cover described in Patent Document 1 as the above-mentioned electrical connection device. In the earth leakage prevention type outlet and the outlet cover, the earth leakage prevention type outlet is configured to have an eave integrally. Here, the eaves are integrally formed with the leakage prevention type outlet so as to protrude above the insertion port.

As a result, even if there is a gap between the plug into which the blade is inserted into the outlet and the outlet, the gap is covered with an eave from the top of the gap, so that the blade is exposed to the gap. Try to prevent electric leakage by eliminating the accumulation of dust.

However, even if the eaves are formed in the outlet as described above, when the dust wraps around the eaves and reaches the above-mentioned gap, the dust accumulates in the above-mentioned gap. In particular, as mentioned above, cleaning between the outlet and the plug located in the gap between the kitchen wall and the back wall of the refrigerator is rarely done, so dust is on the surface of the outlet between the double-edged blades of the plug. Is easy to accumulate. Therefore, it must be said that it is difficult to prevent electric leakage even if the eaves are formed in the outlet as described above. Further, in order to integrally form the eaves with the outlet, an extra manufacturing process or the like is required, which is troublesome.

It should be noted that the above is not limited to the refrigerator, but the same applies to, for example, home appliances such as televisions arranged in the living room through a gap in the wall.

Therefore, even if a fire or fire occurs due to the tracking phenomenon, it is required that the fire or fire can be properly extinguished.

In addition, not only the fire caused by the fire caused by the tracking phenomenon, but also the short circuit of the wiring that is likely to occur due to the disconnection due to the twisting of the wiring near the outlet, and the galling of the wiring near the outlet by small animals such as mice. It is required that fires caused by fires caused by short circuits of wiring, which are likely to occur, can be extinguished.

Therefore, in order to deal with the above, the present invention utilizes a fire extinguishing composition to instantly extinguish a fire caused by a fire at the source of the fire even if the fire occurs at the source of the fire due to a tracking phenomenon or other causes. It is an object of the present invention to provide a sheet-shaped fire extinguishing member, an electric connection device using the sheet-shaped fire extinguishing member, a roll-shaped fire extinguishing tape for forming a sheet-shaped fire extinguishing member, and a method for forming the sheet-shaped fire extinguishing member.

In solving the above-mentioned problems, the sheet-shaped fire extinguishing member according to the present invention is according to the description of claim 1.
A fire extinguishing sheet (33, 61) made of an aerosol fire extinguishing sheet formed by solidifying the composition into a sheet with a binder as the main composition of an organic potassium compound and an inorganic potassium compound as additives. , The film (34, 62) laminated on the fire extinguishing sheet by adhesion with a synthetic resin adhesive and the fire extinguishing sheet laminated on the fire extinguishing sheet by adhesion with a synthetic resin adhesive so as to face the film via the fire extinguishing sheet. It is provided with a detachable sheet (36, 64).

According to this, a sheet-shaped fire extinguishing member made by utilizing an organic potassium compound as an additive and an inorganic potassium compound as a main composition is used on the fire extinguishing sheet after peeling off the release sheet from the fire extinguishing sheet. , When the product is attached to an object to be attached such as an outlet cover, the above-mentioned organic potassium compound and inorganic potassium according to the temperature rise due to the fire of the fire source located near the object to be attached. A fire caused by a fire at the source of the fire with an aerosol based on the smoke produced by the chemical reaction of the compound, and the fire is extinguished instantly without involving the object to be attached located near the source of the fire or an object located near the fire. Can be.

Therefore, the sheet-shaped fire extinguishing member can be provided as a self-extinguishing fire extinguishing member that can extinguish a fire instantly without depending on another fire extinguisher with its own fire extinguishing sheet.

In the sheet-shaped fire extinguishing member, in the state before the release sheet is peeled off, the fire extinguishing sheet is protected from the back surface side by the release sheet, so that between the fire extinguishing sheet and the release sheet. The synthetic resin adhesive is not directly exposed. Therefore, the sheet-shaped fire extinguishing member is convenient in handling without being sticky due to the adhesive action of the adhesive.

Further, according to the description of claim 2, the electric connection device using the sheet-shaped fire extinguishing member according to the present invention is described.
It is provided with an outlet (10) having an insertion side end (11a) and an outlet cover (30a) that is attached to the outlet from the insertion side end side so as to open the insertion side end of the outlet to the front thereof. ..

In the electrical connection device
A fire extinguishing sheet (33), a synthetic resin film (34) laminated on the fire extinguishing sheet by adhesion with a synthetic resin adhesive, and adhesion with a synthetic resin adhesive so as to face the film via the fire extinguishing sheet. Therefore, it is provided with a sheet-shaped fire extinguishing member (30b) composed of a release sheet (35) laminated on the fire extinguishing sheet.
In the sheet-shaped fire extinguishing member, the fire extinguishing sheet is formed by solidifying the composition into a sheet with a binder, with the main composition being an organic potassium compound to which a plasticizer is added as an additive and an inorganic potassium compound. Consists of an aerosol fire extinguishing sheet formed
The sheet-shaped fire extinguishing member is formed by peeling off the release sheet from the fire extinguishing sheet and then using the fire extinguishing sheet to adhere to the outlet cover in the vicinity of the end of the outlet on the insertion side. It is characterized by being attached.

According to this, the outlet cover is attached to the outlet from the insertion side end side so as to open the insertion side end portion of the outlet to the front thereof. In addition, the sheet-shaped fire extinguishing member is attached to the vicinity of the outlet cover on the plug-in side end of the outlet cover by peeling off the release sheet from the fire extinguishing sheet and then using the fire extinguishing sheet to adhere with a synthetic resin adhesive. It is attached. Along with this, even if the sheet-shaped fire extinguishing member is attached to the outlet cover, the sheet-shaped fire extinguishing member is located near the end on the insertion side of the outlet.

Here, for example, an outlet is arranged together with an outlet cover at the lower part of the inner wall of the kitchen of a house, and a refrigerator is provided on the back wall thereof with a gap between the outlet and the lower part of the above-mentioned inner wall in the kitchen. It is assumed that they are arranged so as to face each other.

In such an arrangement state, the connection cord extending from the back wall of the refrigerator is connected to the insertion side end of the outlet by the plug. As a result, the refrigerator is supplied with power from a commercial power source via an outlet and a connection cord, and is put into an operating state.

As mentioned above, once the plug of the refrigerator connection cord is connected to the outlet, the connection will continue for a long time due to the inherent nature of the refrigerator. In addition, since there is only a gap between the back wall of the refrigerator and the inner wall of the kitchen, the surface of the end on the insertion side of the outlet is in a position where it is difficult to clean. Therefore, dust easily adheres to the surface of the end on the insertion side of the outlet.

Therefore, if the connection state of the plug with the insertion side end of the outlet continues for a long period of time as described above, dust adheres to the surface of the insertion side end of the outlet or the connection boundary between the outlet and the plug. go. Further, the dust absorbs the moisture in the air, so that the dust tends to cause a short-circuit state in which electricity can be supplied.

Specifically, the connection to the plug's outlet plug-in end is made by inserting the plug's double-edged blades into both outlets formed at the outlet's plug-in end, while the plug is a commercial power source. It is in a state of being powered from the outlet via an outlet.

Therefore, if the dust is in a state where it is likely to cause a short circuit in which energization is possible as described above, the dust containing water as described above is likely to cause a short circuit between the two blades of the plug or a short circuit inside the outlet. Become. Along with this, the dust ignites due to the heat generation and causes a tracking phenomenon, which causes a dangerous situation such that not only the plug and the outlet are involved in the fire but also the kitchen is involved in the fire.

However, since the sheet-shaped fire extinguishing member is located near the end on the insertion side of the outlet as described above, the sheet-shaped fire extinguishing member is located near the connection boundary between the outlet and the plug. Therefore, the heat-generating energy associated with the fire of dust, which is the source of the fire, quickly and instantly reaches the sheet-shaped fire extinguishing member while raising the heat-generating temperature.

Along with this, the fire extinguishing sheet of the sheet-shaped fire extinguishing member instantly causes a smoke phenomenon due to a chemical reaction between the organic potassium compound and the inorganic potassium compound as the exothermic temperature of the heat generation energy rises, and the aerosol based on this smoke phenomenon occurs. Therefore, fires involving outlets and plugs can be extinguished instantly. Therefore, even if the outlet or plug is involved in a fire, damage to the outlet or plug can be minimized.

Further, the above description is not limited to the short circuit due to the tracking phenomenon, and may be similarly established even if the short circuit is caused by the twist of the wiring connected to the outlet, for example.

Further, since the sheet-shaped fire extinguishing member can extinguish a fire with the fire extinguishing sheet as described above, the sheet-shaped fire extinguishing member has a fire extinguishing function of the fire extinguishing sheet without depending on other fire extinguishing devices or the like. Since the fire can be extinguished, it can be provided as an excellent self-extinguishing fire extinguishing member.

Further, according to the third aspect of the present invention, the present invention relates to the electrical connection device using the sheet-shaped fire extinguishing member according to the second aspect.
The outlet cover has a cover wall (31) forming an opening (31b) corresponding to the insertion side end portion of the outlet, and extends in an inclined shape from the outer peripheral portion of the cover wall toward the outside of the back side thereof. Equipped with an annular flange (32)
In the outlet cover, the cover wall is assembled to the outlet so that the above-mentioned insertion side end of the outlet is fitted into the opening so that the annular flange extends from the cover wall to the outlet side in an inclined manner. And
The sheet-shaped fire extinguishing member is made of the synthetic resin in the fire extinguishing sheet so as to be superposed on the opening of the cover wall at the opening (36) formed so as to correspond to the opening of the cover wall. It is characterized in that it is attached to the cover wall by the adhesion of the adhesive.

According to such a configuration, the action and effect of the invention according to claim 1 can be achieved more specifically.

Further, according to the description of claim 4, the electric connection device using the sheet-shaped fire extinguishing member according to the present invention is described.
It comprises an outlet (10) having a plug-in side end (11a).

As a result, the refrigerator is supplied with power from a commercial power source via an outlet and a connection cord, and is put into an operating state.

Once the refrigerator connection cord plug is connected to the outlet as described above, the connection will continue for a long time due to the inherent nature of the refrigerator. In addition, since there is only a gap between the back wall of the refrigerator and the inner wall of the kitchen, the surface of the end on the insertion side of the outlet is in a position where it is difficult to clean. Therefore, dust easily adheres to the surface of the end on the insertion side of the outlet.

Therefore, if the connection state of the plug with the insertion side end of the outlet continues for a long period of time as described above, dust adheres to the surface of the insertion side end of the outlet or the connection boundary between the outlet and the plug. go. Further, the dust absorbs the moisture in the air, so that the dust tends to be in a state of causing a short circuit state in which electricity can be supplied.

Therefore, when the dust is in a state of causing a short circuit in which energization is possible as described above, the dust containing water as described above causes a short circuit between the two blades of the plug and a short circuit inside the outlet. Along with this, the dust ignites due to the heat generation and causes a tracking phenomenon, which causes a dangerous situation such that not only the plug and the outlet are involved in the fire but also the kitchen is involved in the fire.

However, since the sheet-shaped fire extinguishing member is directly arranged at the end on the insertion side of the outlet as described above, the sheet-shaped fire extinguishing member is located at the connection boundary between the outlet and the plug. There is. Therefore, the heat-generating energy associated with the fire of dust, which is the source of the fire, reaches the sheet-shaped fire extinguishing member more quickly and instantly while raising the heat-generating temperature.

Along with this, the fire extinguishing sheet of the sheet-shaped fire extinguishing member instantly causes a smoke phenomenon due to a chemical reaction between the organic potassium compound and the inorganic potassium compound as the exothermic temperature of the exothermic energy rises, and the aerosol based on this smoke phenomenon is used. The fire can be extinguished instantly without involving the outlet, plug, and thus the kitchen.

Further, since the sheet-shaped fire extinguishing member can extinguish a fire with the fire extinguishing sheet as described above, the sheet-shaped fire extinguishing member has a fire extinguishing function of the fire extinguishing sheet without depending on other fire extinguishing devices or the like. Since the fire can be extinguished, it can serve as a self-extinguishing fire extinguishing member and can be provided as an excellent self-extinguishing fire extinguishing member. Other effects are the same as those of the invention according to claim 1.

As shown in FIGS. 1 and 2, the outlet cover 30a is formed of synthetic resin so as to integrally have the cover wall 31 and the annular flange 32. The annular flange 32 is bent from the outer peripheral portion of the cover wall 31 toward the back surface side of the cover wall 31 and extends in an inclined manner.

The outlet cover 30a configured in this way has an annular flange 32 so as to face the opening H3 of the plate wall portion H2 of the inner wall H via the metal plate 20 on the cover wall 31 of the plate wall portion H2. It is attached to the plate wall portion H2 so as to be seated on the outer peripheral portion of the opening portion H3. Here, the mounting is performed on each mounting hole portion 31a (see FIG. 2) formed in the upper and lower intermediate portions of the cover wall 31, and each mounting hole portion 22 of the metal plate 20 with respect to each of these mounting hole portions 31a (FIG. 3). Each screw (not shown) is fastened to the plate wall portion H2 through (see).

Further, the cover wall 31 is formed by forming an opening 31b at the central portion thereof. Along with this, in the outlet 10, the annular flange 12 is accommodated in the opening 31b of the cover wall 31 and is seated on the outer peripheral edge of the opening 21 of the metal plate 20.

The sheet-shaped fire extinguishing member 30b is composed of a fire extinguishing sheet 33, a film 34 laminated on the fire extinguishing sheet 33, and a release sheet 35 laminated on the fire extinguishing sheet 33 from the side opposite to the film 34. (See Fig. 4). Here, the film 34 is laminated on the fire extinguishing sheet 33 by adhering it to the fire extinguishing sheet 33 from the surface side thereof with an acrylic adhesive. On the other hand, the release sheet 35 is laminated on the fire extinguishing sheet 33 by adhering to the fire extinguishing sheet 33 from the back surface side with an acrylic adhesive.

In the first embodiment, the release sheet 35 is peeled off from the fire extinguishing sheet 33 when the sheet-shaped fire extinguishing member 30b is attached to the cover wall 31 as described later. Therefore, FIG. 4B is shown. Then, the release sheet 35 is shown by a two-dot chain line. For this reason, the sheet-shaped fire extinguishing member 30b may be grasped as having a configuration including a fire extinguishing sheet 33 and a film 34, or as a configuration including a fire extinguishing sheet 33, a film 34, and a release sheet 35. May be good.

The fire extinguishing sheet 33 is made of a sheet-shaped aerosol fire extinguishing sheet formed by binding and solidifying an aerosol fire extinguishing agent composition manufactured by Yamato Protec Co., Ltd. with a binder which is a binder. Here, the aerosol fire extinguishing agent composition contains an organic potassium compound and an inorganic potassium compound added as an additive as a main composition.

Under such a configuration, the aerosol fire extinguishing sheet, which is the fire extinguishing sheet 33, causes the organic potassium compound and the inorganic potassium compound, which are the potassium compounds, to undergo a chemical reaction as the temperature of the fire source rises to about 300 ° C. It instantly smokes, and the aerosol produced by this smoke breaks the combustion chain caused by the fire at the source of the fire and exerts the function of instantly extinguishing the fire target. The film 34 is formed in the form of a film from a synthetic resin such as nylon, and the film 34 is laminated on the fire extinguishing sheet 33 from the surface side thereof by adhesion with an acrylic adhesive (see FIG. 4B). ). As a result, the film 34 plays a role of protecting the fire extinguishing sheet 33.

In the first embodiment, the sheet-shaped fire extinguishing member 30b has an opening 36 (hereinafter, also referred to as a common opening 36) common to the fire extinguishing sheet 33, the film 34, and the release sheet 35, and the opening 31b of the cover wall 31. (See FIGS. 4 (a) and 4 (b)). Along with this, in the outlet 10, the annular flange 12 is housed inside both the common opening 36 of the sheet-shaped fire extinguishing member 30b and the opening 31b of the cover wall 31 described above, and the opening 21 of the metal plate 20 is accommodated. It is designed to sit on the outer peripheral edge of the.

In the sheet-shaped fire extinguishing member 30b, the fire extinguishing sheet 33 is adhered to the surface of the cover wall 31 of the outlet cover main body 30a with an acrylic adhesive on the back surface thereof. This adhesion is such that the common opening 36 of the sheet-shaped fire extinguishing member 30b faces the opening 31b of the cover wall 31 in an overlapping manner.

Here, a method of forming the sheet-shaped fire extinguishing member 30b configured as described above by using the roll-shaped fire extinguishing tape 40 (see FIG. 5A) will be described.

The roll-shaped fire extinguishing tape 40 is schematically shown in FIG. 5 (a), but the roll-shaped fire extinguishing tape 40 has a strip-shaped fire extinguishing sheet layer 41 and the fire extinguishing tape as shown in FIG. 5 (b). A three-layer laminated structure 40a composed of a band-shaped film layer 42 laminated on the sheet layer 41 from the front surface side and a band-shaped release sheet layer 43 laminated on the fire extinguishing sheet layer 41 from the back surface side is rolled. It is composed by winding.

FIG. 5B shows only the two three-layer laminated structure 40a of the roll-shaped fire extinguishing tape 40. In the first embodiment, the fire extinguishing sheet layer 41 is formed by forming the above-mentioned aerosol fire extinguishing agent composition manufactured by Yamato Protec Co., Ltd. into a fire extinguishing tape shape as an aerosol fire extinguishing sheet layer with a binder as a binder. The width of the roll-shaped fire extinguishing tape 40 is wider than the width of the sheet-shaped fire extinguishing member 30b described above.

In the first embodiment, in each laminated body 40a, the fire extinguishing sheet layer 41 and the film layer 42 are laminated by bonding with an acrylic adhesive. Here, the acrylic adhesive joins the fire extinguishing sheet layer 41 and the film layer 42 by its curing. Further, the fire extinguishing sheet 41 and the release sheet layer 43 are laminated by adhesive with an acrylic adhesive. However, the adhesive strength of the acrylic adhesive is weaker than that of the acrylic adhesive. Therefore, the release sheet layer 43 can be peeled off from the fire extinguishing sheet 41 while maintaining the bonded state between the fire extinguishing sheet layer 41 and the film layer 42.

Further, in the roll-shaped fire extinguishing tape 40, the release sheet layer 43 of the outer three-layer laminated structure 40a and the fire extinguishing sheet layer 41 of the inner three-layer laminated structure 40a are laminated by adhesion with a rubber adhesive. It is done with it. Here, since the adhesive strength of the rubber-based adhesive is weaker than the adhesive strength of the acrylic adhesive described above, the outer three-layer laminated structure 40a is inside when the roll-shaped fire extinguishing tape 40 is rewound from the end end of the winding. When peeling from the three-layer laminated structure 40a, the outer three-layer laminated structure 40a is detached while maintaining the adhesive state between the fire extinguishing sheet 41 and the release sheet layer 43 of the outer three-layer laminated structure 40a. The sheet layer 43 can be peeled off from the film 42 of the inner three-layer laminated structure 40a.

When forming the above-mentioned sheet-shaped fire extinguishing member 30b from the roll-shaped fire extinguishing tape 40 configured as described above, the square of the sheet-shaped fire extinguishing member 30b is formed from the rewinding tape portion of the roll-shaped fire extinguishing tape 40. Cut out the square ring fire extinguishing tape part corresponding to the ring. The square annular fire extinguishing tape portion cut out in this way is formed so as to correspond to the sheet-shaped fire extinguishing member 30b.

After peeling the release sheet 35 from the square annular fire extinguishing tape portion corresponding to the sheet-shaped fire extinguishing member 30b thus formed, the sheet-shaped fire extinguishing member 30b is covered with the fire extinguishing sheet 33 to cover the outlet cover 30a. It is attached to the wall 31 from the surface side by adhesive with the acrylic adhesive member. In this case, the adhesive is applied so that the common opening 36 of the sheet-shaped fire extinguishing member 30b overlaps the opening 31b of the cover wall 31.

In the first embodiment configured as described above, for example, it is assumed that a refrigerator (not shown) is arranged on the floor surface La (see FIG. 1) in the kitchen described above. Here, it is assumed that the refrigerator is arranged on the back surface thereof so as to face the self-extinguishing electric connection device D via a gap.

In such a state, it is assumed that the connection cord extending from the back wall of the refrigerator is connected to the outlet 10 of the electric connection appliance D by the plug 50 (see FIG. 1). It is assumed that the connection is made by inserting the double-edged 52 of the plug 50 into the pair of left and right insertion hole portions 13 of the outlet 10 from the both insertion ports 13a.

As a result, the refrigerator is operated by being supplied with power from a commercial power source (not shown) via an outlet 10, a plug 50, and a connection cord thereof. The plug 50 is composed of a plug main body 51 and a double-edged blade 52 extending in parallel with each other from the end surface 51a of the plug main body 51.

However, in the electrical connection device D configured as described above, the connection / disconnection of the plug 50 to the outlet 10 is performed by inserting / removing the double-edged 52 of the plug 50 to / from the pair of left and right insertion holes 13 of the outlet 10. To. As a result, power is supplied to the refrigerator and the power is stopped.

Normally, the refrigerator is maintained in an operating state with the plug 50 connected to the outlet 10. Such a maintenance state is maintained for a long period of time due to the inherent nature of the refrigerator. However, there is only a gap between the back surface of the refrigerator and the plate wall portion H2 of the inner wall H of the kitchen. Therefore, since the surface of the outlet 10 is in a position where it is difficult to clean, dust easily adheres to the surface of the outlet 10.

Therefore, as described above, when the plug 50 double-edged 52 outlet 10 is inserted into both insertion holes 13 of the outlet base 10b for a long period of time, dust is collected from the insertion side end portion 11a of the base body 11 of the outlet base 10b. It enters between the plug 50 and the end surface 51a of the plug body 51 and adheres to the plug body. By absorbing the moisture in the air, the adhering dust tends to cause a short-circuited state in which electricity can be applied.

When dust in such a state adheres between the double-edged blades 52 of the plug 50, the voltage of the commercial power supply is applied to the double-edged blades 52 via the outlet 10 as described above, so that the double-edged blades 52 are in the meantime. It will be short-circuited through dust that is likely to cause a short-circuited state. Due to this short circuit, a tracking phenomenon is caused, and the dust causes a fire due to the heat generation.

However, in the first embodiment, the sheet-shaped fire extinguishing member 30b is attached to the surface of the cover wall 41 of the outlet cover 30a as described above. Therefore, as shown in FIGS. 1 and 2, the sheet-shaped fire extinguishing member 30b is positioned so as to surround the insertion side end portion 11a of the outlet 10 from the periphery thereof. This means that the sheet-shaped fire extinguishing member 30b is located close to the surface of the outlet substrate 10b.

Therefore, when the dust ignites due to the heat generated and causes a fire as described above, the heat generated by the fire immediately reaches the fire extinguishing sheet 33 of the sheet-shaped fire extinguishing member 30b. Along with this, the potassium-based compound in the composition contained in the fire extinguishing sheet 33 is instantly smoked by a chemical reaction as the temperature of the heat generated by the exothermic energy rises to about 300 ° C. or higher. Then, the aerosol is generated in the form of smoke due to this smoke formation, and instantly moves to the boundary portion between the outlet base 10b of the outlet 10 and the plug body 51 of the plug 50.

As a result, the fire caused by the fire of dust at the boundary between the outlet base 10b of the outlet 10 and the plug body 51 of the plug 50 is extinguished instantly, and the chain spread to the outer periphery of the fire is instantly cut off. In this way, a fire caused by a fire at the boundary between the outlet 10 and the plug 50 can be extinguished instantly at the time of occurrence without causing the fire to spread to the surroundings of the outlet 10, the plug 50, the kitchen, and the like.

As described above, the sheet-shaped fire extinguishing member 30b causes the fire phenomenon caused by dust at the boundary between the outlet 10 and the plug 50 to be involved in the fire by the fire extinguishing action of the fire extinguishing sheet 33 itself. The fire can be extinguished instantly. As a result, according to the sheet-shaped fire extinguishing member 30b, the fire can be extinguished satisfactorily by the sheet-shaped fire extinguishing member 30b itself without depending on the fire extinguishing by another fire extinguisher. This means that the electric connection device D can be satisfactorily established as a self-fire extinguishing type electric connection device under the fire extinguishing action of the fire extinguishing sheet 33 itself.

Further, such an electric connection device D is established as a self-fire extinguishing type electric connection device only by attaching the sheet-shaped fire extinguishing member 30b to the surface of the cover wall 31 of the outlet cover 30a with the fire extinguishing sheet 33. By using the electric connection device D, it is possible to provide a very convenient and safe self-extinguishing fire extinguishing device without causing a situation of artificially extinguishing a fire unlike other fire extinguishers.

When forming the above-mentioned upper sheet-shaped fire extinguishing member 60 from the roll-shaped fire extinguishing tape 40, a fire extinguishing tape portion corresponding to the shape of the sheet-shaped fire extinguishing member 60 is cut out from the rewinding tape portion of the roll-shaped fire extinguishing tape 40. The fire extinguishing tape portion cut out in this way is formed as corresponding to the upper sheet-shaped fire extinguishing member 60 by hollowing out each portion corresponding to the pair of left and right narrow common openings 63 of the upper sheet-shaped fire extinguishing member 60. Will be done. The fire extinguishing tape portion corresponding to the lower sheet-shaped fire extinguishing member 60 is also cut out from the roll-shaped fire extinguishing tape 40 and formed as in the case of the upper sheet-shaped fire extinguishing member 60.

Of the fire extinguishing tape parts corresponding to the upper and lower sheet-shaped fire extinguishing members 60 formed in this way, each fire extinguishing tape part corresponding to the upper sheet-shaped fire extinguishing member 60 has a release sheet part corresponding to the release sheet 64. It is peeled off from the fire extinguishing sheet portion corresponding to the fire extinguishing sheet 61 to form an upper sheet-shaped fire extinguishing member 60, and the fire extinguishing sheet 61 is used with an acrylic adhesive from the surface side of the outlet portion 13a of the outlet substrate 10b of the outlet 10. It is sticky (see FIGS. 6, 7 and 9). This adhesion is made so that the pair of left and right narrow common openings 63 of the upper sheet-shaped fire extinguishing member 60 coaxially correspond to both the insertion ports 13a of the outlet 10.

Further, in the lower sheet-shaped fire extinguishing member 60, as in the case of the upper sheet-shaped fire extinguishing member 60, after the release sheet 64 is peeled off from the fire extinguishing sheet 61, both outlets of the outlet 10 are inserted into the fire extinguishing sheet 61. It is adhered to the portion 14a from the surface side thereof with an acrylic adhesive. This adhesion is made so that the pair of left and right narrow common openings 63 of the lower sheet-shaped fire extinguishing member 60 coaxially correspond to both the insertion ports 14a of the outlet 10. Other configurations of the second embodiment are the same as those of the first embodiment.

In the second embodiment configured as described above, the electric connection device D1 is different from the electric connection device D in which the sheet-shaped fire extinguishing member 30b is provided on the outlet cover 30a as described in the first embodiment. The upper and lower side sheet-shaped fire extinguishing members 60 are attached to the upper and lower side insertion ports 13a and 14a of the outlet base 10b of the outlet 10 from their respective surface sides. Along with this, the double-edged 52 of the plug 50 is inserted into both the insertion holes 13 of the outlet substrate 10b through the left and right side openings 63 of the upper sheet-shaped fire extinguishing member 60 from the both insertion ports 13a.

Then, the state of being inserted into both the insertion holes 13 of the outlet substrate 10b of the outlet 10 of the double-edged 52 of the plug 50 via the upper sheet-shaped fire extinguishing member 60 continues for a long period of time as in the case of the first embodiment. Then, dust adheres to the surface of the upper sheet-shaped fire extinguishing member 60 and the surface of the plug body 51 of the plug 50, and also enters and adheres to the boundary portion between the upper sheet-shaped fire extinguishing member 60 and the plug body 51 of the plug 50. .. By absorbing the moisture in the air, such dust easily causes a short-circuit state in which electricity can be energized, induces a tracking phenomenon, and the dust ignites due to its heat generation, causing a fire.

However, in the second embodiment, the upper sheet-shaped fire extinguishing member 60 is attached to the outlet substrate 10b of the outlet 10 as described above. Therefore, as described above, dust adhering to the surface of the upper sheet-shaped fire extinguishing member 60 and the surface of the plug body 51 of the plug 50 and dust entering the boundary portion between the outlet base 10b of the outlet 10 and the plug body 51 ignite.

It is attached to 51 via a double-edged 52. Along with this, in the third embodiment, the plug 50 and the sheet-shaped fire extinguishing member 60 constitute a self-extinguishing electric connection device (hereinafter, represented by reference numeral D2).

Specifically, the sheet-shaped fire extinguishing member 60 is attached to the end surface 51a of the plug main body 51 on which the double-edged blade 52 extends by adhesive with an acrylic adhesive. This attachment is such that the double-edged blade 52 is inserted through a pair of narrow common openings 63 of the sheet-shaped fire extinguishing member 60. Other configurations are the same as those in the second embodiment.

In the third embodiment configured as described above, unlike the second embodiment, the electrical connection device D2 has one of the upper and lower sheet-shaped fire extinguishing members 60 of the second embodiment as a sheet. As the fire extinguishing member 60, it is attached to the plug body 51 of the plug 50 as described above.

Along with this, a fire caused by a fire at the boundary between the outlet 10 and the plug 50 via the sheet-shaped fire extinguishing member 60 does not involve the outlet 10 and the plug 50 and thus the kitchen in the fire at the time when the fire occurs, and the fire is instantly even faster. Can be extinguished.

In this way, the sheet-shaped fire extinguishing member 60 attached to the plug body 51 of the plug 50 is dusted at the boundary portion between the outlet 10 and the plug 50 via the sheet-shaped fire extinguishing member 60 due to the fire extinguishing action of the fire extinguishing sheet 61 itself. Since the fire phenomenon caused by the above can be extinguished more quickly and instantly, the sheet-shaped fire extinguishing member 60 can be satisfactorily extinguished by the sheet-shaped fire extinguishing member 60 itself without depending on the fire extinguishing by another fire extinguishing device. can. This means that the electric connection device D2 can be established as an excellent self-extinguishing electric connection device under the fire extinguishing action of the fire extinguishing sheet 61 itself.

Further, in the third embodiment, unlike the second embodiment, the sheet-shaped fire extinguishing member 60 is attached to the plug 50 itself, but the plug 50 is attached to both outlets 10 with its double-edged 52. Since the outlet 10 is connected to the outlet 10 by inserting it into the insertion hole portion 13, the source of the fire due to dust is in the immediate position with respect to the sheet-shaped fire extinguishing member as in the second embodiment. Therefore, in the third embodiment, as in the second embodiment, the fire caused by the fire can be extinguished more quickly and instantly as described above.

Further, the electric connection device D2 configured as described above is established as a self-fire extinguishing type electric connection device by simply attaching the sheet-shaped fire extinguishing member 60 to the plug body 51 of the plug 50 with the fire extinguishing sheet 61. Therefore, by using the electric connection device D2, it is possible to provide a very convenient and excellent self-extinguishing fire extinguishing device without causing a situation of artificially extinguishing a fire unlike other fire extinguishers. ..

Similarly, sticking by adhesive is performed. In this case, since the fire extinguishing sheet member 30b is in a state of having the release sheet 35 before its attachment, it is not affected by the adhesion of the acrylic adhesive and is convenient for handling. It should be noted that such a thing can be similarly established in the second or third embodiment.
(7) In carrying out the present invention, in the roll-shaped fire extinguishing tape 40 for forming a sheet-shaped fire extinguishing member (see FIG. 5) described in the first embodiment, a strip-shaped layer formed on the fire extinguishing sheet layer 41 from the back surface side thereof. Instead of the release sheet layer 43 of the above, a band-shaped adhesive layer (hereinafter, also referred to as a band-shaped adhesive layer 43) formed along the back surface of the fire extinguishing sheet layer 41 may be adopted.

Here, the band-shaped adhesive layer 43 is provided along the back surface of the fire extinguishing sheet layer 41 with an acrylic adhesive that adheres the band-shaped release sheet layer 43 described in the first embodiment to the back surface of the fire extinguishing sheet layer 41. Adhesive is formed.

Along with this, the roll-shaped fire extinguishing tape 40 for forming a sheet-shaped fire extinguishing member has a strip-shaped fire extinguishing sheet layer 41 and a strip-shaped film layer 42 bonded along the surface of the strip-shaped fire extinguishing sheet layer 41 with the acrylic adhesive. The strip-shaped adhesive layer formed along the back surface of the strip-shaped fire extinguishing sheet layer 41 with an acrylic adhesive is formed into a roll shape as a three-layer laminated structure.

In this case, the band-shaped fire extinguishing sheet layer 41 of the outer three-layer laminated structure is laminated on the band-shaped film layer 42 of the inner three-layer laminated structure by the adhesion by the band-shaped adhesive layer of the outer three-layer laminated structure. ..

Therefore, when the roll-shaped fire extinguishing tape 40 for forming a sheet-shaped fire extinguishing member having such a structure is rewound, the adhesive strength of the acrylic pressure-sensitive adhesive forming the band-shaped adhesive layer is increased between the band-shaped film layer 42 and the band-shaped fire extinguishing sheet. Since it is weaker than the adhesive strength of the acrylic adhesive that adheres to the layer 41, the outer three-layer laminated structure is attached to the strip-shaped adhesive layer while maintaining the adhesion between the strip-shaped film layer 42 and the strip-shaped fire extinguishing sheet layer 41. Can be easily peeled off from the strip-shaped film layer 42 of the inner three-layer laminated structure while maintaining the above.

In forming the sheet-shaped fire extinguishing member 30b described in the first embodiment by using the roll-shaped fire extinguishing tape 40 for forming the sheet-shaped fire extinguishing member configured as described above, the roll-shaped fire extinguishing tape 40 is used. A tape portion corresponding to the sheet-shaped fire extinguishing member 30b is cut out from the rewinding tape portion. The tape portion cut out in this way is formed so as to correspond to the sheet-shaped fire extinguishing member 30b. This means that the sheet-shaped fire extinguishing member 30b is composed of a fire extinguishing sheet 33, a film 34, and a sheet-shaped adhesive layer formed on the back surface of the fire extinguishing sheet 33.

The sheet-shaped fire extinguishing member 30b formed in this way does not have a release sheet, unlike the first embodiment. Therefore, the sheet-shaped fire extinguishing member 30b directly describes the sheet-shaped adhesive layer formed on the back surface of the fire extinguishing sheet 33 in the first embodiment without the work of peeling off the release sheet. Similarly, it can be conveniently attached to the outlet cover 30a.
