Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power plug, and more particularly to an overseas power plug having a ground terminal.

[0002]

[Prior art]

 As shown in FIG. 2, the power plug attached to the product of the overseas specification has a main body 1, a ground terminal 2 protruding from the main body, a neutral terminal 3, and a live terminal 4. As shown in FIG. 3, the outlet corresponding to the power plug for overseas use has three insertion ports respectively corresponding to the ground terminal 2, the neutral terminal 3, and the live terminal 4. On the other hand, the power plug for domestic use is a bifurcated neutral terminal 3 and a live terminal 4 as shown in FIG. 4, and the corresponding outlet also has two insertion ports as shown in FIG. is there . Therefore, when the product having the above-mentioned power plug for overseas is used in Japan, conventionally, it has been dealt with by using the conversion plug shown in FIG. That is, using a conversion plug (FIG. 5) having a structure in which an outlet for overseas is arranged on one outlet surface 5a of the conversion plug body 5 and a domestic standard power plug is arranged on the other plug surface 5b. Insert the overseas power supply plug (Fig. 2) having a ground terminal into the outlet surface 5a of the conversion plug (Fig. 5), and insert the plug surface 5b of the conversion plug (Fig. 5) into the domestic standard outlet shown in Fig. 6. Was used in. However, such technical means had the following problems.

[0003]

[Problems to be solved by the device]

 That is, with the above-mentioned technical means, the power plug having the earth terminal cannot be used in Japan if the user does not have the conversion plug. Therefore, an object of the present invention is to provide a power plug having a ground terminal that can be plugged into a standard domestic outlet and used domestically and internationally without using a conversion plug.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a power plug for overseas use having a ground terminal, a main body portion, a neutral terminal and a live terminal that project in the same direction from one end surface of the main body portion, and can be retracted at the same end surface. It is characterized by having a ground terminal which is

[0005]

[Action]

 According to the power plug having the above-described configuration, since it has the ground terminal that can be freely retracted and retracted at the one end surface of the main body portion, by immersing the ground terminal in the one end surface of the main body portion, a bifurcated domestic power plug .

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1A is a plan view of a power plug according to the present invention, FIG. 1B is a front view thereof, FIG. 1C is a side view thereof, and FIG. 1D is a perspective view thereof. The power plug shown in these figures includes a main body 1 made of a mold resin, a cylindrical ground terminal 2 made of a conductive material, a plate-shaped neutral terminal 3 made of a conductive material, and a live terminal 4. ing.

The main body 1 has a convex flat surface 1 a on one end surface, and a power cord 7 is connected to the side opposite to the convex flat surface 1 a. The earth terminal 2, the neutral terminal 3, and the live terminal 4 are installed on the convex plane 1a. At the center of the narrow portion of the convex flat surface 1a, a cylindrical groove 1b which fits the outer diameter of the ground terminal 2 is provided perpendicularly to the convex flat surface 1a. Further, a mold resin protrusion 1c of the same quality as that of the main body material is provided on the side surface of the columnar anti-blade 1b.

On the side surface of the cylindrical ground terminal 2, a raceway groove 2a, which becomes a raceway of the mold resin protrusion 1c, is arranged in a U-shape in the vertical direction of the cylindrical shape. The grounding terminal 2 is installed so as to engage with the cylindrical groove 1b of the main body 1 and the mold resin protrusion 1c of the main body 1 is fitted into the raceway groove 2a. Therefore, the movement of the ground terminal 2 inside the cylindrical groove 1b is regulated by the mold resin protrusion 1c and the track groove 2a, and when the molded resin protrusion 1c is located at one end of the groove 2a, the ground terminal 2 is connected to the cylindrical groove 1a. 1b, and the tip reaches the same position as the tips of the neutral terminal 3 and the live terminal 4. On the other hand, when the molded resin protrusion 1c is located at the other end of the raceway groove 2a, the earth terminal 2 has a minimum protrusion from the cylindrical groove 1b.

The neutral terminal 3 and the live terminal 4 are of the same type and have circular holes 3a and 4a at the center of one end in the plate-like longitudinal direction. The neutral terminal 3 and the live terminal 4 are arranged in the widened portion of the convex flat surface 1a of the main body portion 1 so as to face each other in the longitudinal direction of the widened portion, with the circular holes 3a and 4a at the tips. It projects perpendicularly to the convex flat surface 1a.

In the power plug configured as described above, when the mold resin protrusion 1c is normally located at one end of the raceway groove 2a and the earth terminal 2 is projected to the maximum extent from the cylindrical groove 1b, the earth terminal 2 is Like the neutral terminal 3 and the live terminal 4, they project from the main body 1 in the same direction by the same length. Further, the ground terminal 2 is rotated according to the mold resin protrusion 1c and the raceway groove 2a, and further pushed into the cylindrical groove 1b until the mold resin protrusion 1c reaches the other end of the raceway groove 2a. The protrusion from the body 1 is minimized. When the ground terminal 2 protruding to the minimum is picked up and pulled out along the track groove 2a and rotated, the ground terminal 2 projects from the main body 1 in the same direction and by the same length as the neutral terminal 3 and the live terminal 4.

[0011]

[Effect of device]

 As described in detail in the above embodiments, according to the overseas power plug having the ground terminal according to the present invention, since the ground terminal can be freely retracted inside the power plug body, the conversion plug is not used. It can be used domestically and internationally by plugging it into a standard domestic outlet.
