Description

  The present invention relates to a plug that can be easily pulled out from an outlet for use in various electric appliances.

Conventionally, electric appliances have been provided with plugs in the cord for taking in the power, but some of these plugs have a mechanism that can be easily removed from the outlet. For example, when pulling out the plug, if you put your finger on the hook of the plug body, or pinch it with another finger or push the knob, it will be provided at the end of the rod with a spring in the plug body. There is a technology that can be easily pulled out from the outlet by sliding the pull-out base part downward. (For example, see Patent Document 1)
Japanese Utility Model Publication No. 7-36376 (pages 3 to 5, FIG. 2)

  There is a plug technology as shown in the above-mentioned Japanese Utility Model Laid-Open No. 7-36376, but this plug has a spring on a rod with a knob at the upper part and a base at the lower part in the main body having a finger hooking part at the upper part. When the plug is slidably stored in the plug, and is pulled out from the outlet, if you put your finger on the finger hooking part of the plug body and push the knob afterwards, the pulling base provided on the rod end will be pushed out. The plug can be easily removed from the outlet.

  However, the structure is complicated because many components are involved, such as the need to interpose a coil spring on the knob, pull-out base, and rod as well as the plug body having a finger hooking portion, and a high cost factor is inevitable. In addition, in terms of configuration, the cord outlet is a plug technology that has inconveniences and disadvantages such as having to be taken out from the side of the plug body.

  In order to provide a plug in which the inconvenience and disadvantages of the plug as described above are eliminated, in the present invention, in the first aspect, the fixing protrusions are provided on the left and right upper portions of the plug body having the cord at the upper portion and the plug terminal at the lower portion. By providing one end of a curved leaf spring to the fixed projection formed by forming a holding projection having a slide hole in the lower part, and using the other as an insertion plug that is housed in the slide hole, from the outlet When removing the left and right curved leaf springs of the plug body, the curved leaf spring ends are pushed out downward to make the plug lightly come out from the outlet.

  According to the second aspect of the present invention, instead of the curved leaf spring described above, a straight leaf spring protruding from the slide hole by a certain length is used. Normally, the end of the straight plate spring protrudes from the slide hole. However, when the plug is inserted into the outlet, the straight plate spring is pushed in and the middle is bent and fixed. When picked, the end of the straight leaf spring is pushed out and the plug is pulled out.

  The plug according to the present invention has a very simple configuration in which the upper part of the leaf spring is fixed to the left and right of the plug body and the lower part is movably accommodated in the slide hole, so that it can be manufactured at a very low cost regardless of the functional plug. At the same time, the plug has no failure factor. In addition, since the type 1 embodiment uses a curved leaf spring, the curved leaf spring does not come out of the slide hole when plugged into the outlet, but when pulling out, the curved leaf spring protruding to the left and right is picked and slid A curved leaf spring pops out from the hole, so even weak women, children, and elderly people can pull out from the outlet with a light force.

  Furthermore, the plug body of the second embodiment type is the same as the first embodiment type, but since the straight plate spring is provided instead of the curved leaf spring, the end of the straight plate spring usually protrudes from the slide hole. However, when the plug is inserted into the outlet, the straight leaf spring is pushed in and the middle is bent and fixed, but when pulling out from the outlet, the bent portion is picked in the same manner as in Example 1 and lightly pulled out with the same action. It is possible to provide a unique plug that is not seen in the past.

  In order to make the plug lightly removable from the outlet, a curved leaf spring is slidably interposed on the left and right sides of the plug body, and when the curved leaf spring is picked, the tip of the leaf spring protrudes so that the plug can be pulled out with a light force. To do.

  The plug according to the first embodiment of the present invention will be described with reference to a perspective view shown in FIG. 1 and a perspective view showing a state where a spring plate shown in FIG. 2 is pressed. The plug 1 according to the first embodiment is provided with a fixed projection 5 on the upper left and right sides of a plug body 4 having a cord 2 at the top and a plug terminal 3 at the bottom, and a holding projection 7 having a slide hole 6 at the bottom. A plug body 4 is formed, and one of the curved leaf springs 8 bent in an arc shape is fixed to the fixed protrusion 5 of the plug body 4, and the other end is movably movable in the slide hole 6 of the holding protrusion 7. A plug 1 is formed.

  The plug 1 according to the first embodiment is provided with a fixed protrusion 5 and a holding protrusion 7 with a slide hole 6 on the left and right sides of the plug body 4, and fixes one of the curved leaf springs 8 to the fixed protrusion 5. Since it is housed in the slide hole 6 of the holding projection 7, when the plug 1 attached to the outlet 10 is pulled out, the curved plate springs 8, 8 positioned on the left and right of the plug body 4 are gripped. When the end of 8 protrudes from the slide hole 6 and pushes the surface of the outlet 10, the plug 1 moves in the opposite direction and can be pulled out with a light force.

  The insertion plug of Example 2 is demonstrated with the front view which shows the state inserted in the perspective view shown in FIG. 3, and the electrical outlet shown in FIG. The plug 1 according to the second embodiment includes the cord 2 and the plug terminal 3 as in the first embodiment, and is provided with the fixed protrusion 5 and the holding protrusion 7 with the slide hole 6 on the left and right of the plug body 4. One of the straight plate springs 9 protruding from the slide hole 6 by a certain length is fixed to the fixed protrusion 5 and the other end is housed in the slide hole 6 to constitute the plug 1 of the second embodiment.

  The plug body 4 of the plug 1 according to the second embodiment is the same as that of the first embodiment, but the leaf springs provided on the left and right sides thereof are straight straight leaf springs 9 instead of the curved leaf springs 8. Usually, it protrudes from the slide hole 6 by a certain length. When the plug 1 is inserted into the outlet 10, as shown in FIG. 4, the projecting straight leaf spring 9 is fixed while curving both sides as it is pushed. Although there is a repulsive force of the straight leaf spring 9, the force sandwiching the plug terminal 3 is much stronger, so there is no fear of coming off. Further, when pulling out from the outlet 10, if the curved portions on both sides are picked, the spring can be pulled out with a lighter force in combination with the repulsive force that returns the spring to its original shape.

  The curved leaf spring 8 and the straight leaf spring 9 in the present invention are preferably long and thin leaf springs, but may be spring bars having a round cross section. In addition, a dish-like finger contact portion may be provided in the curved portion so that the leaf spring can be easily picked, and the length and hardness of the spring protruding from the slide hole 6 are not particularly limited.

  This proposal is intended for plugs of general electric products, but can also be applied to round plugs used for personal computers and other electric products.

It is a perspective view which shows the insertion plug of Example 1 of this invention. It is a perspective view of the state which pressed the curved spring board of Example 1. FIG. It is a perspective view which shows the insertion plug of Example 2. FIG. It is a front view which shows the state which inserts the plug of Example 2 in an outlet.
