2. Description of the Related Art When a plug is used for a long time in an embedded power supply outlet at home, a tracking phenomenon (causes of electric leakage, fire, etc.) occurs. It is said that this is due to the accumulation of dust between the front plate of the outlet and the front end surface of the plug and the increase in moisture, resulting in lower insulation between the electrodes.

[0003] Therefore, conventionally, the plug-in type outlet is dust,
To protect against leakage caused by factors such as moisture,
For example, JP-A-9-213404 discloses an example of a protective cover for preventing electric leakage.

[0004] However, this protective cover for preventing electric leakage is
An insulative cap that is adhesively fitted to the tip of the plug via an adhesive, and has a pair of through holes through which a pair of left and right insertion electrode plates (ground electrode plates) penetrate. Therefore, since the structure is extremely simple, there is an advantage that it can be manufactured at low cost.

[0005] However, the protective cover for preventing electric leakage having the above-mentioned structure must be individually manufactured in correspondence with plugs of various shapes and sizes, and is an embedded type having a plurality of insertion ports. There was a problem that it did not fit into an outlet. This can fundamentally solve the problem that dust accumulates between the front plate plate of the recessed outlet and the tip of the plug, even if the insulating cap is adhesively fitted to the tip of the plug. Because you can't.

[0006] In particular, in recent years, recessed outlets mounted on home walls have two or three outlets,
Since a plurality of plugs such as refrigerators, microwave ovens, and televisions tend to be inserted into these outlets for a long time, a leakage phenomenon occurs due to a tracking phenomenon that occurs between the embedded outlet and the plurality of plugs. There is a demand for the appearance of a protective cover for preventing electric leakage, which can prevent fire and the like.

[0007]
