[0014]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0015]
Example 1
In the figure, reference numeral 20 denotes a main body made of a plurality of resin molded products provided with a handle 21 at an upper portion, and a heater 22 for heating a vaporization chamber (not shown) for generating steam is incorporated inside the main body 20. The steam is spouted from the steam spouting portion 23 formed of a cloth soft surface provided on the lower surface, and the garment is stretched.
[0016]
24 is a recess provided in the rear part of the main body 20 so as to face the terminal portion of the heater 22, so that a connection plug (not shown) electrically connected to the circuit of the heater 22 can be attached. The main body 20 is formed inwardly from a first opening 25 provided so that the connection plug can be inserted.
[0017]
Reference numeral 26 denotes a holding body that closes the first opening 25 and covers the concave portion 24, and holds a power cord 29 electrically connected to the heater 22 by a screw 28 via a conductive lead wire 27. The holding body 26 electrically connects the circuit of the power cord 29 and the heater 22 to the second opening 30 led out from the main body 20 through the power cord 29 electrically connected to the circuit of the heater 22. A bendable cylindrical protection portion 32 that protects the terminal portion 31 and the power cord 29 led out from the second opening 30 of the holding body 26 is provided.
[0018]
The holding body 26 is composed of a plurality of members, and when a power in the lead-out direction is applied to the power cord 29, an electrical connection portion (for example, the terminal portion 31) between the power cord 29 and the heater 22 circuit. The fixing means for preventing the tension from being applied to the power supply cord 29 includes a power cord 29 disposed between the holding bodies 26 made of a plurality of members, and the power cord 29 is attached to at least one member 33 of the holding body 26. Is provided with a restricting portion 34 that restricts displacement in the derivation direction.
[0019]
The restricting portion 34 is formed by a protrusion formed on one member 33 of the holding body 26, and the power cord 29 is led out by bypassing the power cord 29 so as to surround the protrusion and connecting to the terminal portion 31. The displacement in the direction is restricted. The protrusion may be a protrusion for attaching the other member 35. In addition, the holding body 26 is configured so that the protective member 32 is integrated with the holding body 26 by fixing the other member 35 to the one member 33 with a screw 36.
[0020]
That is, the holding body 26 is a restriction that restricts the terminal portion 31 that is electrically connected to the circuit of the heater 22, the protection portion 32 that is led out from the second opening 30, and the power cord 29 from being displaced in the lead-out direction. The fixing portion constituted by the portion 34 and a plurality of members 33 and 35 having the power cord 29 disposed therebetween are integrally formed with the power cord 29 to form a unit.
[0021]
Further, when the plurality of members 33 and 35 are coupled with the screw 36, the power cord 29 is clamped so that the power cord 29 can be firmly fixed to the holding body 26, and can be attached to the power cord 29 during use or transportation. When a force in the lead-out direction is applied, it is possible to prevent tension from being applied to the electrical connection portion between the power cord 29 and the circuit of the heater 22 and to maintain a good electrical connection.
[0022]
Further, the holding body 26 can be provided with a bendable cylindrical protection portion 32 that protects the power cord 29 led out from the second opening 30 by integral molding, and can facilitate the simplification of the configuration. .
[0023]
A shaft portion 37 is provided on the protective portion 32 led out from the second opening 30 of the holding body 26 so as to protrude in the connecting direction of the plurality of members 33, 35, and the shaft portion 37 is provided with the plurality of members 33, 35. By fitting in the hole 38 provided in 35, the protection part 32 can be provided so as to be rotatable at a predetermined angle in the horizontal direction from the second opening 30 of the holding body 26. This rotation direction can be made vertical by supporting the shaft portion 37 in the horizontal direction, and by rotating in conjunction with the operation of the main body 20, the durability of the power cord 29 can be improved.
[0024]
The operation of the above configuration will be described. The first opening 25 is formed so as to largely open in accordance with the shape of the connection plug to which the power cord 29 can be detachably attached, but when the power cord 29 is fixed to the main body 20 and led out, Since the 1st opening part 25 can be obstruct | occluded with the holding body 26, the penetration | invasion of foreign materials, such as dust, can be prevented. Further, by providing the main body 20 with the power supply terminal 5 for connecting the connecting plaque 11 described based on FIG. 6 instead of the holding body 26, the cord 20 can be easily attached and detached without changing the outer shape of the main body 20. A product can be realized.
[0025]
In the present embodiment, an example of the cord detachable type is shown, but the same effect can be obtained even in a cordless iron that places an iron body on a stand and heats it.
[0026]
