Description

[Detailed Description of the Invention] The present invention relates to a suction plate fixing structure for a magnetic plug holder.

Conventionally, as shown in Fig. 1, a magnetic plug 2 having a magnet 1 at its tip is fitted into a mounting hole 4 of a plug receiver 3 provided on the side of an electric kettle, etc., and fixed to the magnet 1 and the plug receiver 3. A magnetic plug 2 and an electrode pin 6 of a plug receiver 3 are electrically connected to each other to prevent them from falling off by attracting a magnetic attraction plate 5 .

The method for fixing the suction plate 5 to the plug receiver 3 is as follows:
Conventionally, there has been a method of forming an insertion groove 7 opening downward in the plug receiver 3, inserting a flat suction plate 5 into the groove, and then bonding it.
Alternatively, there is a method of inserting the suction plate 5 and then using the upper end surface of the bottom body 8 to prevent the suction plate 5 from being removed. However, in the former case, adhesive work is required, and the plug 2 is repeatedly attached and detached. However, in the latter case, the insertion of the suction plate 5 and the attachment of the bottom plate 8 must be carried out at the same time, making the assembly work troublesome.

The present invention has been made in view of the above drawbacks, and an object of the present invention is to provide a suction plate fixing structure for a magnetic plug holder that can prevent the suction plate from falling off by simply processing the suction plate and is easy to assemble. With the goal.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

In FIGS. 2 and 3, reference numeral 10 denotes a magnetic plug holder made of synthetic resin similar to the conventional one, and this plug holder 10 is provided with a plug mounting hole 11 that opens on one side, and a pair of electrode pins 12. is fixed.

An insertion groove 13 is formed in the center of the plug receiver 10 and is open at the bottom and communicates with the plug mounting hole 11 on one side of the center.

14 is a suction plate made of magnetic material (see Figures 4 and 5)
A claw piece 15 is provided by bending on one side of the suction plate 14 near its lower end, and leg pieces 16 are provided on both sides of the claw piece 15 to project downward.

Note that 17 is a body plate of an electric pot or the like, and 18 is a bottom body, and the upper end of this bottom body 18 closes the opening of the insertion groove 13 of the plug receiver 10.

When the suction plate 14 is inserted into the insertion groove 13 of the plug receiver 10 from below, the claw piece 15 hits the inner surface of the insertion groove 13 and is bent inward, and the lower end of the leg piece 16 is then held with a jig or the like. When pressed, the claw piece 15 touches the inner edge 1 of the plug mounting hole 11.
1a, and is prevented from being pulled out downward.

In this state, the upper end surface of the suction plate 14 comes into contact with the ceiling surface of the insertion groove 13, and the suction plate 14 is positioned and fixed in the vertical direction.

Note that the method for forming the claw pieces 15 on the suction plate 14 is as follows.
It is not limited to the above-mentioned bending process, but may also be an ejection process or a cut-and-raise process.

However, if the bending process is performed as described above, sufficient elasticity can be imparted to the claw piece 15, so the insertion work of the suction plate 14 becomes easy, and there is no fear that the inner surface of the insertion groove 13 of the plug receiver 10 will be chipped. .

As is clear from the above explanation, according to the present invention, the suction plate can be securely fixed to the plug receiver by simply providing a claw piece on the suction plate and inserting the suction plate into the insertion groove. There is no fear that the suction plate will fall off even if the plug is repeatedly attached and detached, and there is no need to simultaneously perform the work of fixing the suction plate and the work of attaching the bottom body, etc., resulting in good assembly workability.

In addition, it has excellent practical effects, such as the fact that a conventional plug holder can be used as is by simply modifying the suction plate.
