Abstract

(57) [Summary] [Purpose] The mounting plate for mounting a printed wiring board is improved to simplify the board mounting work. [Structure] The board mounting plate 10 is conventionally equipped with screw holes 1 at four corners.
Although the present invention has two raised surfaces 11, this invention has only two screw holes 12 and other raised surfaces 11 are provided with key-shaped projections 13. The two mounting holes 2 and 2 of the substrate 1 are formed into the key-shaped protrusions 13 and 13
After the cover 1 is fitted over the base plate 1, the board 1 is slightly moved laterally to hold the key-shaped protrusions 13 and 13 so that the mounting holes 2 and 2 do not float up. It is directly above the screw holes 12, 12. The dimensions are decided as such. Therefore, both the centering work and the screw tightening work are simplified.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a printed wiring board mounting plate.

[0002]

[Prior art]

 A mounting plate for mounting a printed circuit board, which is a rectangular plate with multiple mounting holes, by floating it is usually provided with raised surfaces at the four corners of the rectangular plate material, drilling screw holes in each, and inserting screws into the mounting holes at the four corners of the base plate. It is fixed by tightening it in the screw hole.

[0003]

[Problems to be solved by the device]

 When using the above-mentioned conventional board mounting plate, move the board appropriately so that the four mounting holes on the board are directly above the four screw holes on the plate side, and then align the four screws. I had to screw it in. Preparing and tightening a small screw was also an unexpectedly troublesome task. This invention simplifies that task.

[0004]

[Means for Solving the Problems]

 The printed wiring board mounting plate of this invention is a plate material for floating and mounting a printed wiring board, which is a rectangular plate having a plurality of mounting holes, and it is a raised surface formed by press working at multiple positions on a single plate material. One of the raised surfaces has a screw hole for screwing the mounting hole on one side of the board, and the raised surface on the other side has a key that can be inserted from below into the mounting hole on the other side of the board. The shaped protrusion is folded up.Place the board on the raised surface, fit the mounting hole into the key-shaped protrusion, and then move the base plate slightly laterally to grip the mounting hole edge with the key-shaped protrusion. The feature is that the screw holes, the intervals between the key-shaped projections, and the orientations of the key portions are set so that the other mounting holes are concentric with the screw holes when they are inserted.

[0005]

[Action]

 The board mounting plate of this invention is suitable for mass production and is inexpensive because it is mainly made from a single flat plate by pressing. The key-shaped protrusion not only restrains the board after mounting it on the board, but also simplifies the centering of the mounting hole on the board side and the screw hole on the mounting plate side during assembly. If you move the board so that it hooks on the key of the key-shaped protrusion, the holes will definitely be aligned. The use of key-shaped protrusions reduces the number of screw holes, and the screwing work is halved.

【Example】

 FIG. 1 shows the relationship between an embodiment of the present invention and a substrate attached thereto. 1 is a printed wiring board, 2 is mounting holes at its four corners, 3 is a mounting screw, and the board mounting plate is 10. The raised surfaces at the four corners are 11, the screw holes are 12, and the key-shaped protrusions are 13. . When the four corners of the board 1 of FIG. 1 are placed on the raised surfaces 11 of the four corners of the mounting plate 10, the key-shaped protrusions 13 are easily inserted into the mounting holes 2 of the board. Then, the substrate 1 is laterally moved as indicated by the arrow in FIG. 2, and the hole edge of the mounting hole 2 is pressed below the key portion of the key-shaped protrusion 13 to be gripped. Since the key-shaped protrusion is narrower at the back, it comes to grip.

In the illustrated embodiment, the key portion of the key-shaped projection 13 is oriented toward the screw hole 12, so the substrate 1 is moved in the direction of the arrow in FIG. 2, but the orientation of the key portion is opposite to this. If facing in the direction, the substrate 1 will be moved in the opposite direction. both are fine. As a result, the two mounting holes 2 of the board 1 are constrained, and the remaining two mounting holes 2 are located concentric with the screw holes 12, 12. The orientation of the key part and the space between the screw hole 12 and the key-shaped projection 13 are set so that the hole can be centered with certainty even with the eyes closed.

FIG. 3 shows another embodiment of the raised surface 11. In the embodiment shown in FIG. 1, plate pieces of required dimensions punched out at the four corners of the plate 10 are folded up and bent to form a raised surface 11, and the punched portions in the shape of key-shaped protrusions 13 at the tip thereof are folded up. However, in the case of FIG. 3, it is not just a fold-up, but it is extruded into a truncated cone shape to form the raised surface 11. Even if it is called a truncated cone, it is a semi-cone because the key-shaped protrusion 13 is erected on the raised surface 11. It should be noted that the raised surface 11 on the side having the screw holes 12 (not shown) has a perfect truncated cone shape. In addition to the above-mentioned embodiment, the shape of the raised surface 11 and the key-shaped projection 13 and how to make them can be variously changed and applied by a press engineer.

[0009]

[Effect of device]

 In this invention, when the printed wiring board is mounted on the mounting plate, conventionally, the board is placed on the raised surface of the plate, appropriately adjusted and moved, and the four mounting holes are aligned with the four screw holes on the plate side. The work of holding the product so that it does not move and tightening it with four screws has been dramatically simplified. That is, by fitting the two mounting holes on one side of the board onto the two key-shaped protrusions on the plate side and moving the board in the direction that can be gripped by the key part, the two mounting holes on the other side are the two screw holes on the plate side. It is concentric with, and the installation work is completed only by tightening two screws on it.
