Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printed wiring board support device suitable for small electronic devices.

[Summary of the idea]

The present invention easily and reliably supports printed wiring boards parallel to each other between fixed parts in a small occupied space by a connecting member of the fixed parts and a supporting member extending in a direction perpendicular to the connecting member. This is how it was done.

[Conventional technology]

2. Description of the Related Art Conventionally, small electronic devices such as consumer video cameras have used a plurality of printed wiring boards in order to reduce size and weight, streamline assembly and adjustment, and the like.

First, the schematic configuration of a conventional video camera will be described with reference to Fig. 2. In Fig. 2, the body of the video camera is composed of a front panel 12 to which a lens mount 11 is attached, a back panel 13, a bottom plate 14, and a cover (not shown) whose cross section is substantially inverted U-shaped.

Although not shown in the drawings, for example, a charge-coupled device (CCD) type imaging device may be disposed immediately after the front panel 12, and a socket for connecting a cable may be provided on the outer surface of the back panel 13. , a tripod mounting seat is provided on the lower surface of the bottom plate 14. 15 is a printed wiring board (hereinafter referred to as a parent board), which is appropriately attached to the bottom plate 14, and a plurality of printed wiring boards (hereinafter referred to as child boards) are mounted on this parent board 15.
16a to 16f are attached perpendicularly to the parent board 15 and parallel to each other. Each child board 16a to 16
f is equipped with various circuit systems,
The two central child boards 16c and 16d are connected to the main board 15 by connectors (not shown). Four outer child boards 16a, 16b, 16e
and 16f are provided with a plurality of μ-shaped connection pins at their lower ends, and these connection pins are soldered to the parent board 15.

17 and 18 are, for example, acrylic, butadiene,
The holder is made of synthetic resin such as styrene (ABS), and is provided with the same number of holding grooves 19a to 19f and 20a to 20f as the child substrates 16a to 16f, respectively. The holders 17 and 18 are appropriately screwed to the front panel 12 and the back panel 13, and the grooves 19a to 19f and 20a to 20f hold the upper parts of the front and rear edges of the corresponding child boards 16a to 16f. 16a to 16f are prevented from contacting a cover or an adjacent child board (not shown).

[Problem that the invention attempts to solve]

However, the conventional holders 17 and 18 as described above are not suitable for the front panel 12 and the back panel 1.
3, it was difficult to reduce the space they occupied.

In addition, both holders 17 and 18 and the child board 16
In order to set a to 16f at predetermined relative positions, a jig had to be used to attach both holders 17 and 18, resulting in poor workability.

Furthermore, since conventional holders are designed to hold the leading edge and trailing edge of the slave board, multiple holders are required, which increases costs and causes damage to the slave board due to vertical vibrations and shocks. 16c, 16d
There was a risk that the connector might fall off from the connector on the main board 15.

In view of the above, an object of the present invention is to provide a printed wiring board support device that occupies a small space and can easily and reliably hold a daughter board.

[Means for solving problems]

In the present invention, the solid parts 12, 1 are connected by the fastening member S.
A plurality of printed wiring boards 16a to 16 are attached to the fixed parts 12 and 13 and arranged parallel to each other between the fixed parts 12 and 13.
The fixing parts 12 and 13 are connected in the same direction as f, and the connecting member 21 has an engaging part 25 and an engaged part 35 that engages with the engaging part 25.
This is a support device for a printed wiring board, which includes a support member 31 extending in a direction orthogonal to the plurality of printed wiring boards 16a to 16f, between the edges of the printed wiring boards 16a to 16f.

[Effect]

According to such a configuration, the occupied space is reduced,
Printed wiring boards are easily and reliably supported.

〔Example〕

Hereinafter, an embodiment of the printed wiring board support device according to the present invention will be described.

The configuration of an embodiment of the present invention is shown in FIG. In FIG. 1, parts corresponding to those in FIG. 2 are designated by the same reference numerals and redundant explanation will be omitted.

In FIG. 1, reference numeral 21 denotes a connecting member, which has through holes 22 and 23 at both ends thereof, and projections 25 at bent portions 24 on both sides. Further, the connecting member 21 is provided with a long hole 26 as appropriate. Reference numeral 27 denotes a tripod mounting seat, which is attached to the upper surface of the connecting member 21. Further, corresponding to the through holes 22 and 23 of the connecting member 21, screw holes 12 are provided in each of the extending portions 12a and 13a of the front panel 12 and the back panel 13, respectively.
b and 13b are provided.

31 is a holder made of ABS resin, for example,
The same number of holding grooves 32a to 32f are provided on the lower surface in correspondence with the plurality of daughter boards 16a to 16f, and a wide groove 33 is provided to prevent uneven thickness. In addition, a pair of wide grooves 34 are provided on the upper surface of the holder 31.
