Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair iron that uses a sheet-shaped heater, and allows terminals of the heater to be easily connected within a narrow space.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body cover, 2 is the main body equipped with a switch, a storage battery, etc. inside, 3 is a self-temperature-controlled sheet-like heater, 4 is a heater holder attached to the tip of a holder to be described later, and 5 is a holder. A light emitting diode at the tip emits light while the heater 3 is energized.

6 is a clip for sandwiching hair between the heater 3; 7 is a switch knob for controlling the energization of the heater 3; 8 is a clip push button that opens the clip 6 as shown by the broken line in FIG. 1 when pressed; 9 is the charging connector, 1
0 is a heat insulating material, 11 is a cylindrical holder that holds the inner surface of the heater 3, 12 is an insulating plate attached to the center inside the holder 11,
Reference numerals 13 and 13' designate contact plates that come into elastic contact with the contact portions 3' of the heater, 14 a resistor, 15 lead wires, and 16 rivets that fix the insulating plate 12 and the contact plates 13 and 13'.

Reference numeral 11 denotes a notch for insertion of the contact plate, which is provided at a location facing the contact portion 3'.

To describe the heater part in more detail, the holder 11 is wrapped with a heat insulating material 10, and the contact part 3' of the self-temperature-controlling sheet-like heater 3 is placed on the notch 1 of the holder 11.
Roll it so that it comes to 7.

An insulating plate 12 to which contact materials 13, 13', etc. are attached in advance is inserted into this holder 11 and fixed by an appropriate method.

At this time, the contact plate 13 is always in contact with the contact portion 3' of the self-temperature-controlled heater 3 due to spring pressure.

The above-mentioned hair iron is used to push the clip push button 8 to open the clip 6, insert the hair, and curl the hair wrapped around the heater 3.

In the case of the embodiment, the heater 3 is energized by charging the built-in storage battery in advance.

Here, with a sheet-shaped heater, it is impossible to solder or caulk the terminals, so the methods of connecting the heater and lead wires are limited.

This becomes even more difficult when there are space constraints, such as with this product.

As described above, the present invention is very easy to assemble, since the contact portion of the heater and the contact plate are brought into contact with each other by spring pressure, and all that is required is to insert the insulating plate with the contact plate assembled in advance.

Further, if the contact plate is fixed at approximately the center side as in the embodiment, and extended to touch both ends, the space can be used more effectively.
