Description

  The present invention relates to a power plug for supplying power (electric power) to an electric device by being inserted into an outlet of a power outlet (socket: receptacle) such as a commercial power source. The present invention relates to a power plug that forms a filling member to prevent a tracking fire (fire caused by a short circuit due to accumulation of dust or the like).

  Electrical equipment such as electrical appliances and OA (office automation) equipment includes a power plug that is plugged into a power outlet. In order that the connection terminal member of the power plug can be inserted into the insertion port of the power outlet, the outer dimension of the connection terminal member is slightly smaller than the inner diameter of the insertion port. Therefore, when the connection terminal member of the power plug is inserted into the outlet of the power outlet, dust or the like adheres to the gap between the connection terminal member of the power plug and the outlet of the power outlet, and thus an electrical short (short circuit) Inconvenience may occur.

  In addition, since there is a gap in the connection terminal member of the power plug when it is inserted into the outlet of the power outlet, the power plug tends to rattle at the outlet, and the power plug is inclined with respect to the power outlet. It will be easy to come out from the insertion slot. For this reason, if the power cord of the power plug is accidentally hooked, the power plug can be easily pulled out from the insertion slot, and the power plug is unplugged particularly in office automation equipment that always requires power supply. If the power supply is cut off, the problem of internal data corruption occurs. In order to solve this problem, there is a “power plug” described in Japanese Patent Application No. 07-37388 filed earlier by the present applicant, and its outline will be described as first and second prior application examples.

  The power plug 1 of the first prior application example shown in FIG. 7 includes a plug body 3 and a pair of connection terminal members 4A and 4B inserted into the power plug insertion ports 9A and 9B of the power outlet 2 as shown in FIG. A power cord 5 connected to the electric device is provided.

  The plug body 3 is made of an insulating material having insulation properties such as plastic and synthetic rubber, and the outer shape of the plug body 3 is formed in a substantially rectangular shape. In the plug body 3, a pair of gap filling portions 6A and 6B are formed so as to project integrally when the plug body 3 is molded, on the abutting surface 3A of the power outlet 2 on the side to be inserted into the power plug connection ports 9A and 9B. .

  The gap filling portions 6A and 6B are formed in a rectangular tube shape, and the outer dimensions thereof are substantially equal to the inner diameter dimensions of the power plug connection ports 9A and 9B of the power outlet 2. As shown in FIG. 8, the gap filling portions 6A and 6B are provided with connection terminal insertion holes 7A and 7B having an inner diameter dimension substantially equal to the outer dimension of the connection terminal members 4A and 4B. Further, chamfered portions 8A and 8B are formed at the tip portions of the gap filling portions 6A and 6B, respectively.

  The connection terminal members 4A and 4B are formed of a metal plate, and the base end sides of the connection terminal members 4A and 4B are supported inside the plug body 3 as shown in FIG. 7, and are inserted into the insertion ports 9A and 9B of the power outlet 2. The connection terminal members 4A and 4B are attached to the plug body 3 so that the tip ends of the connection terminal members 4A and 4B on the side protrude from the connection terminal insertion holes 7A and 7B of the plug body 3 as shown in FIG. ing. Therefore, regarding the connection terminal members 4 </ b> A and 4 </ b> B, the outer peripheral wall of the root portion of the portion protruding from the plug main body 3 is covered with the inner peripheral wall of the gap filling portions 6 </ b> A and 6 </ b> B of the plug main body 3.

  The connection terminal members 4A and 4B of the power plug 1 configured as described above are inserted into the power plug insertion ports 9A and 9B of the power outlet 2, respectively. When inserted in this manner, the gaps 10A and 10B generated between the outer peripheral walls of the connection terminal members 4A and 4B of the power plug 1 and the inner peripheral walls of the power plug insertion ports 9A and 9B of the power outlet 2 are The gap filling portions 6A and 6B are filled. As a result, the gaps 10A and 10B disappear and dust and the like are prevented from entering, and the occurrence of rattling is prevented.

  In addition, in the power plug (not shown) of the second prior application example, by providing a gap filling cap (blade cap) separately from the plug body, the blade cap can be attached and detached. This prevents dust and the like from entering the gap.

  However, in the power plug 1 of the first prior application example shown in FIGS. 7 and 8, since the gap filling portions 6A and 6B are integrally formed of the same material as the plug body 3, for example, the plug body 3 When a material such as soft vinyl chloride is used to make the gap, the thickness of the gap filling portions 6A and 6B is so thin that the gap filling portions 6A and 6B are inserted into the outlets 9A and 9B of the power outlet. There is a problem that the durability of the gap filling portions 6A and 6B is lowered.

  In the power plug of the second prior application of the prior application, a blade cap is provided separately so that it can be attached to and detached from the plug body. However, since the blade cap does not have means for connecting to the plug body, a force to push the plug body downward is applied, or when the blade cap is about to be detached, the inserted blade cap is not attached to the base of the plug body. The connection terminal members 4A and 4B are separated from the blade cap and dust or the like may enter the gap.
