Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a plug socket.

[0002]

[Prior art]

 The existing plug socket solves many problems of conventional two-hole sockets.

[0003]

[Problems to be solved by the device]

 However, this type of plug socket is not applicable to a three-pronged or four-pronged plug in its space and shape. An object of the present invention is to provide a plug socket. Another object of the present invention is to provide a plug socket applicable to three-pronged and four-pronged plugs.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the plug socket of the present invention includes members such as a base portion, a protection plate, a spring, an electric conductor, an upper cover, a lower cover, and the like. Hold or fit a spring between the shaft tubes of the plate, install diagonal teeth at the opposite positions of the fitting cylinder and the shaft tube, and rotate the protection plate, making circular cuts that are all plug holes on the upper cover. Is provided with an arc-shaped oblique guide plate that protrudes inward, and a protrusion is provided on the control plate at a position facing the plug hole.The protrusion presses the oblique edge of the arc-type oblique guide plate to protect it. A slanting pyramid is provided on the protruding upper surface of the plate, and when combining the upper cover and the lower cover, the base part is inserted into the inside, and the defense plate receives the force of the spring and is pushed upward, so the plug hole is formed. Although sealed, the plug legs are all in the plug holes at the same time. When it is pushed in, the projecting oblique pyramid is pressed down to help rotate the protective plate in one direction, and the diagonal plate provided at the relative position between the fitting tube and the shaft tube prevents the protective plate from rotating. When the plug legs move away from the protective plate, they come into contact with the conductor, the protrusions of the protective plate are pushed laterally, and the plugs are pulled out. Moving upward again, the protrusion presses down on the oblique edge of the arc type oblique guide plate, returns to the original position and seals the plug hole.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, Embodiment 1 of the present invention is applied to a plug 7 having a three-legged plug leg 71, and includes a base portion 1, a protection plate 2, a spring 3, electric conductors 4, 41, an upper cover 5, It includes members such as the lower cover 6. The inner base part 1 is provided with a fitting cylinder 11 and a T-shaped protection part 12 on the upper part thereof, and the electric conductors 4, 41 and the lead wire 42 are attached on the base part 1 by the bolts 43 and the nuts 44, and the protection plate 2 is attached. Is provided with a shaft tube 21 corresponding to the fitting tube 11, diagonal teeth 111 are provided at opposite positions of the fitting tube 11 and the shaft tube 21, and the protection plate 2 is rotated. A proper number of protrusions 22 are provided at positions facing the three-pronged plug leg 71, and an oblique pyramid 221 is provided on the protrusions 22. A projecting arc type oblique guide plate 52 is provided, and an oblique guide edge 521 is formed on the arc type oblique guide plate 52.

FIG. 2 is an assembly diagram of the first embodiment of the present invention. Between the fitting cylinder 11 on the base portion 1 and the protection plate biaxial pipe 21, a spring 3 which is pressed or fitted is inserted, and the protrusion 22 presses one end of the arc-shaped oblique guide plate 52 and oblique guide edge 521. When the upper cover 5 and the lower cover 6 are combined, the base portion 1 is inserted therein, and the defense plate 2 receives the force of the spring 3 and is pushed upward, so that the plug hole 51 is sealed.

[0007] Figures in use are shown in FIGS. 3 to 5. When all of the plug legs 71 of the plug 7 are inserted into the plug holes 51 at the same time, they push the oblique pyramids 221 of the projection 22 of the protection plate 2, so that the protection plate 2 rotates in one direction, and the fitting tube 11 and the shaft tube are rotated. The helical teeth 111 and 211 provided at the position facing 21 apply mutual force, and the protection plate 2 rotates until it is localized. This is as shown in FIGS. 3 and 4, and when the plug leg 71 and the defense plate 2 separate, they come into contact with the conductors 4 and 41, and the defense plate 2 moves upward under the force of the spring 3. Since the projection 22 pushes the oblique guide edge 521 of the arc-shaped oblique guide plate 52, the protection plate 2 tries to rotate to the original position, but the projection 22 simultaneously applies a lateral force to the side surface of the plug leg 71. Finally, the plug 7 is stably put into the inserted state. When the plug 7 is pulled out and each plug leg 71 is detached, the protection plate 2 moves upward, and the protrusion 22 pushes the oblique guide edge 521 of the arc-shaped oblique guide plate 52 to return to the original position, Seal the hole 51.

FIG. 6 shows a second embodiment of the present invention. This is used for a four-pronged plug, and the difference between this and Example 1 is that the number of protrusions 23 and the number of pyramids 231 is one more than in Example 1. The protrusion 23 and the oblique pyramid 231 correspond to the number and position of the plug legs. Of course, it can be implemented without increasing the number. In addition, the shapes of the conductor 1 and the conductors 4 and 41 attached to the base portion 1 and the upper portion of the embodiment of the present invention are not limited to those shown in the drawing of Embodiment 1 and the drawing of Embodiment 2; If 41, 41 is changed to a straight rod-shaped body, it can be improved to an array type plug, and in addition to this, it can also be applied to household appliances such as a split type (main body cordless type) iron.

[0009]

[Effect of the invention]

 As described above, the plug socket of the present invention has a feature that it can be applied to a three-pronged or four-pronged plug. As a result, it is effective for applying to other array type plugs and separate type (main body cordless type) home appliances.
