DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed wiring board locking device for locking a printed wiring board in a housing and a printed wiring board locking structure.

[0002]

2. Description of the Related Art Conventionally, a printed wiring board is locked in a housing by, for example, fixing the printed wiring board to the housing with screws or the like. That is, as shown in FIG. 23, spacers 3 such as spacing bolts are fixed to the four corners of the bottom 1a of the housing 1 with screws 5 or the like.

On the upper part of the spacer 3, a screw 5 or the like is used.
The printed wiring board 7 is fixed. Printed wiring board 7
A power supply cord 9 for supplying power to the printed wiring board 7 is directly attached 11 on the upper side. The power cord 9 is introduced from an introduction hole 1c formed in the side surface 1b of the housing 1,
It is fixed to the conduction hole 1c via a cord bush 13 fitted into the introduction hole 1c.

In addition, four corners of the printed wiring board 7 are shown in FIG.
As shown in FIG. 4, a through hole 7a for inserting the screw 5 is formed, and a prohibited area 7b for component mounting and pattern wiring is formed around the through hole 7a.

[0005]

However, as described above, when the printed wiring board 7 is fixed to the housing 1, the printed wiring board 7 is fixed to the housing 1 with screws 5 or the like. In addition, when the printed wiring board 7 is attached to and detached from the housing 1, it must be performed by attaching and detaching the screws 5 and the like, and there is a problem that a large amount of time is required for screwing work.

In particular, when evaluating a prototype, the printed wiring board 7
In general, when correcting the wiring pattern of
In many cases, the printed wiring board 7 is frequently attached to and detached from the housing 1. In such a case, every time the wiring pattern is corrected, the screws 5 fixed at the four corners are removed and the printed wiring board 7 is removed. The plate 7 must be removed from the housing 1,
There is a problem that a large amount of time is required for correction work and evaluation.

Further, since an area for fixing the spacer 3 must be formed on the printed wiring board 7, it is impossible to mount components and lay out wiring patterns of signal lines in this area. There is a problem that the component mounting efficiency of the printed wiring board 7 and the layout efficiency of the wiring pattern are reduced.
