Description

[Detailed explanation of the idea] Industrial applications This invention relates to an electric rice cooker.

BACKGROUND ART Conventionally, in electric rice cookers of the type in which the power cord is directly connected to the electric rice cooker, a hole is made on the back side of the main body and the power cord is stopped by cord bushing, or a cord box 17 is connected as shown in Fig. 3. In the structure used, the power cord 18 is fitted into the groove 19, held down by a stopper plate 20, and both ends are fixed with screws 21 and 22. The core wire of the power cord 18 extends linearly and is connected to terminal fittings 23a, 23b, and 23c.

Problems that the invention attempts to solve: However, with the above structure, the screw 2
1 and 22 are required, and when the power cord 18 is held down by the stop plate 20, it is difficult to tighten it at first because the stop plate is floating. Also power cord 18
Since the cables extend straight without folding back and are connected to the terminal fittings 23a, 23b, and 23c, there are problems such as if the power cord is pulled too hard, the power cord may shift and the connection may come off, creating a risk of short circuit. Ta.

This invention solves the above problems and can be securely fixed inside the cord box with a single screw, so that even if the cord is pulled from the outside, it will not come off the connection part.
The purpose is to provide a structure that does not shift.

Means for Solving the Problems In order to achieve the above object, the present invention includes a code box attached to the outer surface of the bottom of the main body, and one end of the code box is located outside the main body, and the other end is located inside the main body. a power cord fixed to the cord box by a stopper plate and connected to one end of the terminal fitting; internal wiring connected to the other end of the terminal fitting; and the cord box. The power cord, which is fixed by the stop plate, is placed on a rib provided in the groove of the cord box, and one end is engaged with the cord box from above, and the other end is engaged with the cord box. The cord box is crimped with the stop plate screwed onto the cord box, and the core wire is bent back onto the stop plate and then connected to the terminal fitting.

Function: In this invention, a cord box is attached to the outer surface of the bottom of the main body, and a terminal fitting is provided inside the cord box, one end of which is located outside the main body, and the other end is located inside the main body, and a power cord is connected to one end. Since the other end is wired internally, all power cords are located externally. Therefore, there is no need for contact with high temperature parts within the main body, and there is no need for heat-resistant protection.

Furthermore, in the present invention, when attaching the power cord, one end of the stopper plate is engaged with the cord box, so that the present invention does not lift up due to the cord box, and can be reliably assembled with a single screw. What's more, the power cord is sandwiched between a groove in the cord box and a stopper plate, so it won't easily shift even when force is applied. Furthermore, even if the power cord shifts, there is a core wire of the power cord that is bent back from the end of the stopper plate, so it will not shift any further. Therefore, the danger of a short circuit due to disconnection between the power cord and the terminal fitting is eliminated.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.

FIG. 1 is an exploded view of the cord fixing structure attached to the bottom of the electric rice cooker body, in which 1a is a cord box and 1b is a cover, which is attached to the cord box 1a from the outside. 2a and 2b are Z
Letter-shaped terminal fittings 2c are grounding terminal fittings, each of which is incorporated into the cord box 1a.

Reference numeral 3 denotes a power cord, which is introduced into the cord box 1a and fixed by screws 4 between the stopper plate 5 and the cord box 1a. The core wire of this power cord 3 is connected to each terminal fitting 2a, 2b,
2c. Also, internal wiring 7
a, 7b are terminal fittings 2 extending inside the main body.
It is connected to the other ends of a and 2b by screws 8a and 8b. The cover 1b is attached to the bottom outer surface of the main body 10 via the cord box 1a with screws 9a, 9b. The back plate 11 is screwed to the main body 10 with screws 12, and the earth terminal fitting 2c is also connected to the main body with screws 13.

FIG. 2 is an exploded view of the cord attachment part according to the present invention, in which one end 5a of the stopper plate 5 is connected to the cord box 1.
a, and pass the power cord 3 between the stop plate 5 and the ribs 15 and 16 provided in the groove of the cord box 1a, and then tighten the stop plate 5 with the screw 4.
is tightened to the cord box 1a to secure the power cord 3. As shown in FIG. 1, each core wire 3a, 3b, 3c is bent back with a stopper plate 5 in between and connected to each terminal fitting 2a, 2b, 2c.

In this embodiment, the power cord 3 is arranged on ribs 15 and 16 in the groove provided in the cord box 1a,
One end is engaged with the engaging portion 14, and the other end is held down by a stop plate 5 which is fastened with a screw 4, and the power cord is fixed between the stop plate 5 and the ribs 15, 16. Furthermore, since the core wire of the power cord 3 is folded back onto the stop plate 5 and then connected to one end of the terminal fitting, its fixation is ensured, and even if the power cord is pulled, the connection part with the terminal fitting is not connected to the terminal fitting. It is designed not to affect the

Effects of the invention As described above, according to the invention, the power cord is connected to one end of the terminal fitting outside the main body via the cord box, and the internal wiring is connected to the other end. I no longer get any heat. Furthermore, the power cord is sandwiched between a rib provided in the groove of the cord box and a stop plate that can be hooked on one end to the engaging part of the cord box and the other end is screwed, and the power cord is held in place and fixed. The core wire is folded back and bent to sandwich the stopper plate, and then connected to each terminal fitting, so it can be easily installed with a single screw, and the power cord can be securely fixed. Therefore, even if the power cord is pulled from the outside and is pulled out of place, since the core wire is bent and wired, it will stop against the stop plate, and no force will be applied to the connection with the terminal fitting, making it extremely safe. Its practical effects are great.
