In FIG. 1, various electronic components 27, heat-generating electronic components 28, a heat radiating plate 29, an upright connector 30 and the like are mounted on a printed circuit board 26. In FIG. 2, a bag body 31 for accommodating the printed circuit board 26 is provided in a part of the bracket 37, and the inside of the side surface of the bag body 31 holds the outer periphery of the printed circuit board 26 when the printed circuit board 26 is inserted. The insert frame 33 is provided. Bag 3
The outer wall portion 32 of the bag body forming part 1 is provided with an opening portion 36 into which the connector housing 34 can be inserted.

The operation of the above structure will be described with reference to FIGS. 2 and 3. First, when the printed circuit board 26 is inserted into the bag body 31, the insertion frame 33 inside the bag body 31 is provided along the outer periphery of the printed circuit board 26. If the printed circuit board 26 can be inserted into a predetermined position, the connector housing 34 connected to the lead wire 35 is inserted into the opening 36 of the bag outer wall 32.
Through to the upright connector 30 on the printed circuit board 26. In this state, when the printed circuit board 26 tries to come out of the bag body 31, the connector housing 34 connected to the printed circuit board 26 hits the bag body outer wall portion 36 to prevent the printed board 26 from coming off. On the other hand, printed circuit board 2
When the 6 is taken out from the bag 31, the printed board 26 can be easily taken out from the bag 31 by first taking out the connector housing 34 connected to the printed board 26.

As described above, according to this embodiment, the printed circuit board can be easily taken out from the electric blower by using the connector to prevent the printed circuit board from coming off.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, various electronic components 27, heat-generating electronic components 28, a heat radiating plate 29, an upright connector 30 and the like are mounted on a printed circuit board 26. In FIG. 2, a bag body 31 for accommodating the printed circuit board 26 is provided in a part of the bracket 37, and the inside of the side surface of the bag body 31 holds the outer periphery of the printed circuit board 26 when the printed circuit board 26 is inserted. The insert frame 33 is provided. Bag 3
The outer wall portion 32 of the bag body forming part 1 is provided with an opening portion 36 into which the connector housing 34 can be inserted. Further, as shown in FIG. 4, a pawl 39 is provided on the outer peripheral portion of the connector housing 34, and the pawl 39 is provided to the outside by elastic force.

The operation of the above structure will be described with reference to FIGS. 2 and 4. First, when the printed circuit board 26 is inserted into the bag body 31, the insertion frame 33 inside the bag body 31 extends along the outer periphery of the printed circuit board 26. If the printed circuit board 26 can be inserted into a predetermined position, the printed circuit board 26 can be inserted through the opening 36 of the outer wall 32 of the bag body while pressing the connector housing 34 connected to the lead wire 35 with the finger 39.
It is connected to the upright connector 30. In this state, when the printed circuit board 26 tries to come out of the bag body 31, the connector housing 3 connected to the printed circuit board 26.
The outer wall portion 36 of the bag 4 is prevented from coming off. Further, the pawl 39 of the connector housing 34 is opened to the outside by elasticity, and the connector housing 34 and the bag outer wall portion 32 are connected to each other, so that the connector housing 34 does not come out of the bag outer wall portion 32. At the same time, the rattling of the printed circuit board 26 in the vertical direction can be reduced. On the other hand, when the printed circuit board 26 is taken out from the bag body 31, the connector housing 34 connected to the printed circuit board 26 is pulled out while pressing the claw 39 with a finger, so that the printed circuit board 26 can be easily taken out.
You can take out more.

As described above, according to the present embodiment, the printed circuit board can be easily taken out from the electric blower by using the connector to prevent the printed circuit board from coming off, and in the normal state. The connector can be prevented from coming off, and the rattling of the printed circuit board can be reduced.

[0018]

As is apparent from the above description of the embodiments, the present invention has the printed circuit board which can be easily taken out from the electric blower. Therefore, when the printed circuit board fails, it can be easily replaced. Since it can be performed without damaging the electric blower, it is possible to provide an electric vacuum cleaner having good serviceability.
