Problems solved by technology

However, conventional countermeasures such as this lead to a reduction in the manufacturing efficiency of circuit boards and an increase in manufacturing costs.
In addition, there are also unsatisfactory cases such as increased constraints on the circuit design of the circuit board.
In addition, there is a problem that the size of the circuit board itself is enlarged and the space for housing the circuit board in the electrical equipment increases due to the enlargement of the pattern and the arrangement of the reinforced jumper wires.

Abstract

The electrical cover (1) protects a printed board (4) being mounted on an electric apparatus. A metal plate (3) for circuit available as a large current circuit being connected with the printed board (4) is insert molded. Electric apparatus and assembly method of electric apparatus.

Description

technical field [0001] The present invention relates to an electrical shield for protecting internal circuit components of an electrical device, an electrical device having the electrical shield, and an assembling method of the electrical device. Background technique [0002] For example, as a circuit board for a control circuit (printed circuit board. It is referred to as a "circuit board" in some cases below) to be mounted on various electrical equipment such as home appliances such as air conditioners, there are not only The control circuit is also provided with a circuit board for a high current circuit such as a power supply circuit (for example, refer to IP Patent Laid-Open No. 10-119543). [0003] As shown in FIG. 13, for example, in the case of a home air conditioner, driving of the indoor unit 51 and the outdoor unit 53 is controlled by a control circuit formed on a circuit board 52 mounted on the indoor unit 51. Generally, in addition to the control circuit descri...
