[Detailed description of the invention] (a) Field of the invention This invention relates to, for example, a portable hair iron for applying permanent waves or straight hair to women's hair.

(b) Background of the invention When connecting the power cord to the hair iron described above, as shown in Fig. 3, a pair of clamping bodies 2 and 3 are connected.
After the side portions of the pivot portions 1a
The power cord 5 is connected to the side of the

However, when wiring the power cord 5 mentioned above,
As shown in FIG. 4, electric heating plates 4 are individually fixed to the opposing surfaces of both holding bodies 2 and 3, and a heater 6 is attached to the back side of this electric heating plate 4, and then a Insert the power cord 5 into the cylindrical pivot 3a, then pull out the end of the power cord 5 through the insertion hole 3d opened in the center of the pivot 3a, and then pull the end of the power cord 5 through the insertion hole 3d. Since the connection terminals 6a of the heater 6 are soldered, the wiring of the power cord 5 is time consuming, and the power cord 5 is bent to the back side of both the clamping bodies 2 and 3 and soldered while maintaining this state. Therefore, the cord end 5a of the power cord 5 and the connection terminal 6 of the heater 6
There is a problem that the contact position with a... is easily shifted and requires skill to connect.Furthermore, after the heater 6 is attached to the electric heating plate 4 described above, the power cord 5
Since the hair iron 1 is connected to the heater 6, there is a problem in that the number of steps required to assemble the entire hair iron 1 increases, and the work time required for the assembly becomes longer.

(c) Purpose of the invention This invention forms a groove in one of the pivot parts constituting the pivot parts of both clamping bodies, which communicates from the opening on the side of this pivot part to the central part, so that the power cord can be connected to the heater. To provide a hair iron which can be assembled in a connected state, which simplifies the assembly of a power cord, and at the same time simplifies the assembly process and improves the efficiency of the assembly work.

(d) Summary of the invention This invention provides a cylindrical pivot part constituting the pivoting part of both clamping bodies, with a groove communicating with an opening on the side surface of the pivot part at a position corresponding to the back surface of the clamping bodies. The hair iron is characterized in that a power cord introduced from the opening side of the side surface of the pivot portion is inserted into each groove and connected to a heater.

(E) Effect of the invention According to this invention, from the opening on the side of the pivot,
Since the power cord is inserted into the groove that communicates with the central part of the pivot, the heater and power cord can be assembled with the power cord connected to the heater in advance. This eliminates the hassle of inserting and assembling the power cord into the
Assembling the power cord becomes easy.

Moreover, since the heater and the power cord are integrated, it is easy to handle the parts during assembly, and at the same time, the entire hair iron assembly process is simplified, increasing the efficiency of the assembly work. be able to.

(F) Embodiment of the invention An embodiment of the invention will be described below in detail based on the drawings.

The drawings show a portable hair iron, and in FIGS. 1 and 3, the hair iron 1 has a pair of clamping bodies 2 and 3 made of heat-resistant synthetic resin, which are pivotally attached to the sides so that they can be opened. , and both holding bodies 2 and 3
The electric heating plates 4, 4 are respectively fixed to the opposing surfaces of the electric heating plates 4, 4, and the back surfaces of the electric heating plates 4, 4 are
Heaters 6, 6 to which power cords 5 are connected are individually mounted, and covers 7, 7 made of synthetic resin are fitted on the back sides of both holding bodies 2, 3.

As shown in FIG. 2, the pair of clamping bodies 2 and 3 described above have cylindrical pivot parts 2a and 3a formed in the width direction on each side of both clamping bodies 2 and 3, and, After inserting the two cylindrical shafts 8, 8 through the side openings of both the pivot parts 2a, 3a, the two cylindrical shafts 8, 8 are fixed with long screws 9, and both the clamping bodies 2, 3 can be opened. It is centrally supported by

In addition, both the above-mentioned clamping bodies 2 and 3 are attached to both the pivot parts 2 and 3.
A biasing means (not shown) such as a spring is interposed in a and 3a to always bias the opening angle.

One of the clamping bodies 3 has a groove 3 that communicates from an opening on the side surface to the center at a radially opposing position of the pivot portion 3a corresponding to the back surfaces of both clamping bodies 2 and 3.
b, 3b are formed, and each groove part 3b, 3b
is formed in the length direction of the pivot portion 3a to a length that reaches the center of the pivot portion 3a, and a power cord 5, which will be described later, is provided so as to be wireable to the back surfaces of both the holding bodies 2 and 3.

Further, the cylinder shaft 8 that is inserted into the above-mentioned pivot portion 3a side is formed with notches 8a, 8a that are inserted into the above-mentioned grooves 3b, 3b.

As shown in FIG. 1, each of the aforementioned heaters 6, 6 connects to each electric heating plate 4, 4 through a rectangular square hole 2c, 3c formed in the center of both the holding bodies 2, 3.
The power cord 5 is connected to each connecting terminal 6a exposed on the upper surface of each heater 6, 6.

As shown in FIG. 2, the above-mentioned power cord 5 is inserted into a pull-out stopper 10 made of elastic synthetic rubber, and then split into two pieces within the pull-out stopper 10, and both ends of the cord are separated. 5a, 5a are soldered to the connection terminals 6a, . . . of the respective heaters 6, 6.

To wire this power cord 5, after inserting the cylindrical shaft 8 into the pivot portion 3a of one of the clamping bodies 3, connect both cord ends 5a, 5a of this power cord 5 to the respective grooves 3b, 3b of the pivot portion 3a. At the same time, arc-shaped locking plates 11, 11 are attached to both sides of the retainer 10, and in this state, the retainer 10 is press-fitted into the cylinder shaft 8.

At this time, both the locking plates 11, 11 hold the retaining tool 10, and the protrusions 11a, 11a formed on the outer surfaces of both the locking plates 11, 11 engage the locking tool 10 formed on the inner peripheral surface of the cylinder shaft 8. It engages with the portions 8b, 8b to prevent the power cord 5 from coming out and rotating.

Thereafter, the fixing ring 12 is screwed into the opening on the side of the pivot 3a.

Each of the above-mentioned electric heating plates 4, 4 is formed of, for example, an aluminum alloy by alumite processing, and
The opposing surfaces of each electric heating plate 4, 4 are formed into a corrugated shape that matches when they are joined.

Incidentally, each of the electric heating plates 4, 4 described above may be replaced with a spare plate whose opposing surfaces are formed flat.

In the hair iron 1 configured in this way, when installing the power cord 5 connected to each heater 6, 6, it is necessary to connect the power cord 5 connected to each heater 6, 6 from the opening on the side of the pivot 3a formed in one of the clamping bodies 3 to the center of the pivot 3a. Since the cord ends 5a, 5a of the power cord 5 are individually inserted into the communicating grooves 3b, 3b, with the cord ends 5a, 5a of the power cord 5 connected to each heater 6, 6 in advance, Each heater 6, 6 and the power cord 5 can be assembled, and the power cord 5 can be easily assembled.

Moreover, by assembling the heaters 6, 6 and the power cord 5 in pairs, the process of assembling the hair iron 1 as a whole can be simplified and the efficiency of the assembling work can be increased.
