Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a control device for washing machines, dryers, dishwashers, etc. used in general households.

Conventional configuration and problems thereof Conventionally, in this type of control device, as shown in FIG. Generally, the housing 3 and the connector 4 connect the circuit of the printed wiring board 1 to the power source and the load. However, in this configuration, there are man-hours for attaching the lead wires 2 one by one to the printed wiring board 1 and man-hours for caulking the connector 4 to the lead wires 2. This man-hour is required to connect the housing 3 and connector 4 to the printed wiring board 1.
However, the problem arises as to how to ensure the creepage distance of the different electrode terminals as a countermeasure against tracking caused by the demand for miniaturization of the printed wiring board 1 and washing water, etc.

Purpose of the invention The present invention solves these problems and provides a control device that improves safety and reduces costs.

Composition of the Invention The control device of the invention includes a plurality of connectors for connecting a commercial power source and a load, a housing that accommodates one or more connectors, and a control device that is connected to the commercial power source and the load via the connector, and that controls the load. It is equipped with a printed wiring board mounted with electronic components that perform This is to ensure the creepage distance of connectors of different polarities.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 2 to 4, 5
Connectors a, 5b, 5c, 5d, and 5e are housed in a housing 6 and mounted on a printed wiring board 7 like other electronic components. 8 is a commercial power supply, which is supplied to the control device through the connectors 5a and 5b. Reference numerals 9 and 10 indicate capacitor motors, which are activated by capacitors 11 and 12, respectively, and are connected to the control device by the connectors 5c, 5d, and 5e, respectively. 13 is the capacitor motor 9 and 1 which is the load of this control device.
14 is a control circuit that generates a signal to control the power control element 13;
5 indicates that the parts within the broken line are mounted on the printed wiring board 7.

In the above configuration, the connectors 5a and 5b for supplying commercial power are housed in separate housings 6 as shown in FIG. 3, and the connector 5c is similarly connected to different poles of the capacitor 11.
and 5d are also arranged in separate housings.
Therefore, it is possible to secure a sufficient creepage distance between different poles where tracking may occur.

In addition, in the above embodiment, the connectors 5b and 5c,
5d and 5e are housed in the same housing, but the connectors 5b and 5e are housed in the same housing.
d, 5c, and 5e. In short, it is only necessary that connectors of different polarities, in which tracking may occur, are arranged in separate housings.

Effects of the invention As is clear from the above embodiments, the control device of the invention secures sufficient creepage distance by housing the connectors of different polarities, which have the possibility of tracking, in separate housings. In addition, it can be configured simply by placing the housing independently on the printed wiring board.
Costs can be reduced, and the housing can be placed using the surplus area on the printed wiring board, making it easy to downsize the device. Furthermore, since connectors of different polarities, which may cause tracking, are not housed in the same housing, the structure of the housing can be simplified.
