Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connector for connecting a lead wire to a printed circuit board of a controller of an operating section of a washing machine.

Structure of conventional example and its problems Conventionally, in this type of lead wire connector, Fig. 6 and Fig. 6
As shown in the figure, an upright pin 30 is provided on the printed circuit board 24, and a connector 36 is attached to the pin 30,
It has a connector case 36 that houses this connector 36, and is attached to the printed circuit board 24.

At this time, the lead wire 32 from the connector 35 is connected to the operation plate 19.
Since the wiring is pressed against the back surface of the PC board 24, a large spatial distance between the printed circuit board 24 and the operation panel 19 is required. For this reason, the printed circuit board 24 is in an unstable fixed state, so that when the switch is operated, if the switch is pressed by hand, the printed circuit board 24 is likely to be deformed and cause a problem of malfunction. For this reason, a large number of large and thick printed circuit board mounting bosses 1 of the operation panel 19 are required.

When attaching this printed circuit board 24 to the operation panel 19, the connector 36° connector case 37 and 39 are inserted and fixed into the pins 30 on the printed circuit board 24 in advance, and the lead wires 32 are difficult to assemble. It was in a state.

Also, when repairing the printed circuit board 24, the connector cases 3 and 39 of the connector 36 are also removed at the same time as the printed circuit board 24 is removed, so the lead wires 3
From 2 to 1, workability was in poor condition.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to simplify the processing of lead wires from a printed circuit board, prevent deformation of the printed circuit board, and improve assembly workability.

Structure of the Invention In order to achieve the above object, the present invention fixes a plurality of pins to the printed circuit board of a controller mounted inside the operation panel of a washing machine, and connects the connector U to the pins in the direction of engagement with the pins. A connector case that houses a connector to which a lead wire is electrically conductive and fixed perpendicular to the lead wire is fixed to the operation panel.

Description of Embodiment 1 Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIG. 1, 1 is an outer box body, and 2 is a water tank body installed inside the outer box body 1, which is a washing tub (not shown).

It has a dehydration tank 3. Reference numeral 4 denotes a dewatering capacity built into the dehydration tank 3, and a dehydration hatch 6 having a cloth input port (not shown) and a dehydration lid 6 supported on a shaft so as to be openable and closable are attached to the second part thereof. 7 is a panel stand having a power switch 8, 9 is a washing lid, 10 is an operating section, and 11 is a pedestal. Figure 2 is the first
This is a detailed view of the operation part 10 in the figure. Reference numeral 12 is a substantially rectangular opening provided on the front surface of the water tank body 2 and located on the dehydration tank 3 side, and the lower end thereof is a substantially U-shaped flange. At 13, it is engaged with a holding part 14 formed at the upper end of the outer box body 1. Reference numeral 15 denotes an operation plate holding plate mounted to cover the opening 12, and its upper end is a hook portion 16, which engages with the protrusion 17 of the water tank body 2, and its lower end is attached to the flange portion 13. It is fixed to the aquarium main body 2 at a claw portion 18 to be engaged with the lower end. Reference numeral 19 denotes an operation board, with an operation sheet 20 pasted on the top surface and a plurality of bosses 2 on the back surface.
1 is extended, and a board 24 of a controller 23 mounted with a plurality of electronic chips 22 on a printed circuit board is attached to the boss 21 with screws 25. Reference numeral 26 designates an operation button section formed integrally with the operation panel 19, and a button switch 27 is disposed below the operation button section. 28
is formed integrally with the operation plate 19 and is a draining plate installed in the opening 12, and has an undercut portion 29 at the upper end, which serves as a guide for water droplets to flow to both sides even if they flow from the upper surface.

3 and 4 show details of the printed circuit board 24 and the lead wire connection part of this embodiment, 3o is a pin directly fixed to the printed circuit board 24, and 31 is a connector that is conductively connected to this pin 30. be. This connector 31 has a lead wire 3
2 is electrically conductively fixed, and is formed perpendicular to the direction in which the pin 30 is inserted.

Reference numeral 33 denotes a connector case that houses and insulates the connector 31, and a mounting flange portion of the connector case 33 is integrally formed in the connector case 33.

Further, the connector 31 is housed in the connector case 33, and a rib 19a is formed on the back surface of the operation plate 19 so as to be engaged with the connector case 33 in order to prevent the connector 31 from being removed and to position it. Reference numeral 34 designates a two-connector case, which is integrally formed with a mounting flange portion 34a. This flange portion 34a is fixed to the operation plate 19, and the lead wire 32 side of this double connector case 34 is connected to the operation plate 19 as described above.
The connector 31 is engaged with the rib 19b on the back surface of the connector 31 to prevent the connector 31 from being pulled out and to position the connector 31.

Now, in the above-described embodiment, the connector 31 is conductively crimped and fixed to the lead wire 32 and is housed in the connector case 33 or 34, and the rib 1 is used to prevent disconnection and position the connector 31.
Since the connector cases 33 and 34 are fixed to the operation plate 19 along with the connector cases 9a and 19b, the spring treatment of the lead wires 32 is performed on the back side of the operation plate 19 before attaching the board 24, which improves work efficiency.

Further, when assembling the board 24, the pin 30 of the board 24 is inserted into the connector 31, and then fixed to the boss 21 with the screw 25 to complete the assembly.

In the unlikely event that the board 24 is damaged, when repairing it, use the screws 2
When 5 is removed, only the board 24 can be easily taken out, making repair work easier.

In addition, since the connector 31 is fixed to the operation panel 19,
The spatial distance between the board 24 and the operating panel 19 is reduced, preventing deformation of the board 24 and making the operating section thinner.

Effects of the Invention As is clear from the above explanation, according to the present invention, since a connector with lead wires attached in advance is fixed to the operation panel, it is possible to improve the ease of assembling the board and improve the reliability of lead wire processing. Since the board is located close to the operation panel, deformation of the board can be prevented and the board can be made thinner.

In addition, there is no need to process the lead wires when repairing the board, and workability is significantly improved, which has great practical effects.
