Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plug in which electricity from an outdoor power meter such as a home, office, or factory is plugged into an outlet at the end of a branch circuit that branches into various places indoors by a distribution board. It is about plugs.

[0002]

[Prior art]

 Conventionally, the electricity sent from an outdoor power pole to homes, offices, factories, etc. is usually an AC current of 100 V, and electricity is supplied from a branch circuit outlet to daily-use electric equipment. In recent years, there has been an increasing momentum to increase the household voltage to 200 volts, and of course, factories and the like use 200 volts for power than before. There are three ways to draw in this electricity: three-phase AC three-wire system for factories, office, single-phase two-wire system for sending to households, and single-phase three-wire system. Therefore, looking at the situation where the plugs of electrical equipment were plugged into these indoor wiring sockets, if you plug the plugs all the way in, there will be a copper plate blade receiver inside the outlet that will firmly receive the plug. . Normally, at a voltage of 100 V, the plug consists of two blades, and when the plug is inserted, the wires are connected and current flows from one blade to provide power for lighting and power. Then the current returns to the hole on the other side of the outlet. Furthermore, the outlet of the outlet is parallel and the left side is longer. The longer conductor is grounded from the pole transformer and connected to the ground. There is also a dedicated outlet for electrical equipment that uses 200 volts, and an outlet with a ground terminal that can be connected to the ground wire for products that are used around water such as a washing machine. As mentioned above, outlets and plugs have a very close relationship and form their own interface.

[0003]

[Problems to be solved by the device]

 In the three-phase AC three-wire system, single-phase two-wire system, and single-phase three-wire system of the conventional technology, the current can be passed only after the plug and plug are correctly inserted, and the plug is not inserted easily or is not inserted straight If the contact is poor, the resistance will increase and heat will be generated which may cause a failure such as a fire or short circuit. Further, as described in the section of the prior art, the outlet of the outlet has two rectangular holes in parallel, and the holes are made slightly larger than the blade of the plug. This seems to be due to the clearance within the allowable value with the blade entering the hole. Therefore, even if the blade is inserted into the hole at a right angle and sandwiched by the blade receiver inside the socket, the plug will naturally tilt and a gap will occur between the outer surface of the outlet and the plug. In addition, there is a problem in that the plug may be tilted to cause a gap even when it is lightly touched from above. This gap is about 5 mm in the case of three-phase AC three-wire type dynamic power, and about 2 mm in the case of 100-volt home use. The present invention has been made in view of the above-mentioned conventional problems, and the purpose thereof is to try to close and hold the gap with a cover fitted to the plug when the plug is tilted and there is a gap. It is a thing.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the insertion plug with a cover of the present invention is a plug body with two blades protruding from each other without changing the shape and size of the commercially available plug. A rubber-like soft material having elasticity is fixed to the edge so as to be fitted to form a plug with a cover.

[0005]

[Work]

 When connecting an electrical device with a plug-in plug with a cover according to the present invention to an outlet, press the two blades so that they are straight at a right angle to the outside of the outlet. Spreads around the plug and covers the generated gap. In the case of a power outlet where the main body of the outlet is exposed from the wall surface, cover it with a cover conforming to its shape.

[0006]

【Example】

 An embodiment will be described with reference to the drawings. 1 and 2, the soft cover 1 is fitted and fixed to the main body 2 so as not to be displaced. As shown in FIG. 3, the covering portion A of the soft cover 1 has a larger area than the covering portion B, and the thickness of the edge portion C is thicker than that of the edge portion D. At the same time, the covering portions A and B have four surfaces as shown in FIG. As shown, it was formed so as to spread like a scoop. This is to ensure that the soft cover 1 is evenly and evenly joined to the outer surface of the outlet when the product of the present invention is inserted into the outlet. Next, Fig. 4 shows a state in which the product of the present invention is inserted straight into the socket, and the covering portion A is made slightly longer in the warp-opening direction in consideration of the fact that a gap is inevitably generated. And in FIG. 5, in the case of an exposed outlet, the covering portions A and B are covered so as to wrap and conform to the shape.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

It is possible to prevent an electric shock or a fire accident which occurs when a child puts a 5 yen or 10 yen coin into a clearance of about 2 mm between an embedded outlet and a plug at home. By the way, the thickness of those coins is 1.5 mm.

The gap between the plug and the plug inserted into the outlet of the ventilation fan used at home or in the kitchen such as office is blackened by the steam of water and oil generated from cooking using thermal power, and impurities such as oil are introduced into the gap. It is also easy to enter, and it is possible to prevent electric leakage accidents that occur due to corrosion of the blade.

In the case of a factory that uses a three-phase AC / three-wire power outlet, the gap of about 5 mm easily causes cutting chips and chips generated during machining, which may cause a fire accident. It can be prevented. All of the above three items contribute to the prevention of accidents such as electric leakage, electric shock, and overheating, which are the third factors of electric disasters, by using the product of the present invention.
