DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric appliance such as a household electric appliance, and more particularly to a plug that can be directly attached to an electric appliance without using an electric cord. The present invention relates to improvement of a retractable plug that is stored in a main body case of an electric appliance.

[0002]

2. Description of the Related Art For example, a boil disinfectant for a contact lens or the like is so small that it is difficult to draw out an electric cord therefrom. In addition, there is no particular need for an installation place during use. Some are used with the main body plugged directly into an outlet, and therefore many have a main body case with a retractable plug.

[0003] The storage type plug is one of the storage methods,
There is a method of pivotally attaching a plug to a main body case and rotating the plug. When the plug is not used, the plug is folded and stored in a storage portion on the outer surface side of the main body case, and when used, the plug is rotated in the reverse direction to open to a protruding posture from the main body case. In addition, the plug itself is integrated by attaching the base end sides of two plug blades to a plug body made of plastic or the like, and the base end side of the plug is pivotally attached to the main body case with a rotation shaft in the width direction. .

[0004] A more specific method of mounting the retractable plug, which is rotated in this manner, is shown in FIG.
2, two copper plates 105, 105 also serving as lead wires are attached to the plug blades 102, 102 exposed at both ends of the rotating shaft of the plug body 103 by caulking (X in FIG. 5). 105, 105 as a spring,
There is a method in which the plug body 103 is fixed to the main body case 111 with a screw at intervals. As a result, the plug 101 is axially mounted on the two copper plates 105, 105, and the plug body 103 is formed by the spring force of the copper plates 105, 105.
Therefore, the rotation position can be fixed by the friction, and the rotation of the plug 101 can be restricted. In other words, the plug can be turned to the folded position or the protruding position and stopped.

[0005] As shown in FIG. 6, instead of the above-described copper plate, two plastic attachment portions 105a and 105 are provided.
There is a method in which a is integrally formed with the case main body 111.
That is, the plug body 103 is sandwiched between the shaft attachment portions 105a, 105a via the lead plates 106, 106, and the plug 101 is fixed in the same manner as regulated by the above-described copper plate.
Can be stopped.

[0006] However, although these restrict the rotation, the restricting force is uniform at any rotation angle, and the stabilization at the fully opened position of the plug is not particularly performed.

[0007] For this reason, as shown in FIG. 7, a leaf spring 107 having a concave portion is attached to a main body case 111 near the plug body 103, and when the plug is completely opened, as shown in FIG. The convex portion 104 provided on the body 103 fits into the concave portion of the leaf spring 107. That is, the position is stabilized at the position where the plug 101 is fully opened, which contributes to the operability of the plug.

[0008]

However, since such a leaf spring is a minute part, it is difficult to assemble it and the workability is inferior. Also, such work problems are
If the number of parts increases, the tendency is generally seen. For example, in the case of the plug shown in FIG. 4, the work of caulking a copper plate to the plug blade increases. In addition, it is difficult to manufacture the components themselves if they are minute components, and if the above-mentioned leaf spring is used, the pressing process of the concave portion for fitting is increased, and the burden of these manufacturing is directly reflected in the cost. Would.

Further, the leaf spring is generally made of iron. If the target electric appliance is easily wetted with water, rust is easily caused on the iron leaf spring, and the rust enters inside the electric appliance as dirt. This may cause a failure or break the leaf spring. For example, there is a possibility that the lens preservation solution leaks, such as a boiling disinfector for contact lenses,
Or, the one used around the wash area corresponds to this.

Also, a plug that is not stabilized at the fully opened position causes the plug to be rough when inserted into an outlet, so that if it is not inserted carefully, it may be erroneously folded before being inserted. Then, the operability is inferior.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a retractable plug which can be formed with a small number of parts and which can stabilize the position at the fully opened position of the plug. It is to provide a boiling disinfecting device for contact lenses having the following.

[0012]

Further, a convex portion is provided by integral molding of the plug body, it is projected by integral molding with the housing portion of the stopper portion. Thereby, the above-described configuration can be easily realized. In particular, most of the case main body is made of plastic, so that both the convex portion and the stopper portion are made of plastic. Therefore, a spring having both hardness and elasticity can be easily obtained as compared with a metal spring.

Further , the convex portion is provided so that an outer line in cross section with respect to the rotation axis of the plug body is convex, and the stopper portion is provided so as to correspond to the convex portion. A typical example of the stopper portion is a protrusion protruding from the storage portion toward the plug body, and the stopper should be high enough to be able to push over the contact and get over it while the protrusion contacts the protrusion. I just need. As described above, the convex portion is provided so that the outer line of the cross section with respect to the rotation axis is convex, and can be provided as a protrusion extending in the rotation axis direction. Similarly, the stopper portion is also provided in the rotation axis direction. It can be provided as an extending projection plate. Therefore, the contact surface of the convex portion with the stopper portion also extends in the rotation axis direction and can be widely used, so that wear due to the contact can be suppressed. In addition, the strength of the spring can be increased by the axial length of the stopper portion, so that a strong spring is easily obtained. In addition, since it is easy to form the stopper portion and the like in the axial direction with a uniform length, as a result, it is easy to obtain uniform spring strength.

Further, the convex portion, when folded the retractable plug, by being provided at a position which is exposed to the outer surface of the body case, also serves as the operation unit when the operation of opening the retractable plug folded can do. for that reason,
Even in the case where the plug blade is hidden in the storage section and is difficult to be pulled out, the plug blade can be opened by pushing and turning the convex section.

[0016] The above such retractable plug so used to boil absorber for contact lenses, it is possible to reduce the number of parts, assembly becomes easy, because superior operability.
