Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring board assembly structure in which a plurality of wiring boards are arranged in a housing of an electronic device.

[0002]

2. Description of the Related Art Recently, with the increase in the number of parts of circuit elements that constitute various functional circuits of electronic equipment, for example, functional circuits such as a power supply system, a control system, and a signal output system are formed on different substrates. It is known that a plurality of substrates are arranged in a housing. The plurality of substrates are connected to each other by, for example, a wire rod or a flexible substrate, so that one electronic circuit can be configured to operate the electronic device.

[0003]

However, the number of connecting parts such as wires and flexible boards for connecting each board is required, and the work of attaching these wires and flexible boards becomes complicated and the cost of individual parts is low. Therefore, the cost of the electronic device itself also increases. Further, when it becomes difficult to arrange a plurality of wiring boards in a narrow housing in alignment, it is necessary to mount these boards horizontally or vertically. In this case, a fixing portion for fixing the boards is formed. In addition, there is a problem in that a separate component such as a bracket for fixing the substrate is required, and the cost is high.

[0004]

The present invention has been made to solve the above problems, and includes a first wiring board provided with various functional circuits and a first connector for connection, A second wiring board which is arranged so as to be orthogonal to the first wiring board and provided with various functional circuits and a second connecting connector, and at positions corresponding to the first and second connecting connectors, respectively. A connecting board provided with at least two or more third connecting connectors, and connecting the first and second connecting connectors to the at least two or more third connecting connectors by the connecting board. Also, it is possible to fix them at positions orthogonal to each other. Further, one or a plurality of wiring boards in which the actual areas of the connecting connectors are provided and at least two connecting boards in which the actual areas of the third connecting connector are provided are one parent board. To form a wiring board.

According to the present invention, since a plurality of boards arranged in the housing of an electronic device can be connected and connected and fixed by a connecting board having a connector, for example, a flexible board. It is possible to reduce the cost because it is not necessary to reduce expensive parts such as the above, to form a fixing means for each wiring board, or to prepare a fixing part. Further, since the connection board can be formed by the extra space of the parent board, there is an advantage that the portion that was the waste plate portion can be effectively used.
