Description

[Detailed Description of the Invention] The present invention is an electronic component in which each electronic component such as a volume, a toggle switch, a pilot runner, etc. can be mounted and removed from one side of a support member for mounting the electronic component. Relating to a mounting device.

Conventionally, when connecting electrical components such as a volume to a wiring board, as shown in FIG. By inserting electronic component d into mounting hole C of It prevents you from doing so.

In addition, the terminal f of the electronic component d fixed to the support member directly passes through the wiring board a, is soldered to the back surface g of the wiring board a, and is connected to the circuit pattern installed on the wiring board a. .

However, in this type of device, when each electronic component is repaired or inspected, all electronic components are removed from the support member, and after the support member is removed from the wiring board, each electronic component is soldered in order to be replaced. It is necessary to remove solder from terminals, perform electrical or mechanical inspection, and even electronic components that do not require repair or inspection must be removed from the support member, and the support member must be removed from the wiring. Must be removed from the board.

The present invention eliminates these drawbacks and allows each electronic component to be mounted with one touch from one side of the support member for mounting electronic components.
The purpose of this invention is to provide a removable electronic component mounting device, and the illustrated embodiment will be described.

FIGS. 2 and 3 show perspective views of the electronic component mounting device in an exploded state. First, in FIG. Insert the electronic component 4 (here, the volume) into the mounting hole 8 from below, and connect the male screw part 4-1 of the electronic component 4 with the mounting member 5.
A nut 9 fitted onto the shaft 4-2 of the electronic component 4 from above
As a result, the electronic component 4 is fixed to the mounting member 5.

Next, as shown in FIG. 3, the mounting member 5 to which the electronic component 4 is fixed is drilled into a supporting member 2 having a U-shaped cross section and fixed on the wiring board 1 made of epoxy resin or the like. It is inserted into the mounting hole 6 from the direction of arrow A.

Furthermore, as shown in FIG. 4, the mounting member 5 fitted into the support member 2 has protrusions 3, 3, which are provided on both sides thereof and can freely protrude and retract, each consisting of two bullet members. When it comes into contact with the mounting hole 6 of the
By protruding again after passing through the attachment hole 6, the protrusions 3, 3 and the stopper portions 20, 20 sandwich the attachment hole periphery 10 and are fixed within the support member 2.

On the other hand, the terminals 11 of the electronic component 4 fixed to the mounting member 5 are led to the back surface 13 of the wiring board 1 through the through holes 12 drilled in the wiring board 1, and are soldered to the circuit pattern installed on the surface 13. 14 is given.

In addition, when repairing or inspecting each electronic component, a mounting member 5 to which the electronic component 4 that requires repair or inspection is fixed is provided.
The mounting member is inserted through the mounting hole 6 of the support member 2 by pressing the upright portions 15, 15, 15.15 extending from the upper ends of the four projections 3, 3, 3.3 and standing upward in the direction of arrow B. Remove 5.

Note that the shapes of the mounting member 5 and the protrusions 3, 3, 3.3 are not limited to the illustrated example.

The two-dot chain line indicates the positional relationship between the mounting member 5 and the front panel 16, and 17 is a volume knob.

As described above, according to the present invention, the mounting member 5, which has a U-shaped cross section and has at least one retractable protrusion 3 on each side and has an electronic component 4 fixed to the bottom surface, is used for mounting the electronic component. By making it possible to freely attach and detach from the support member 2, it is possible to remove only the electronic components that require repair or inspection from one side of the support member 2, and to support them again after repair or inspection. It has advantages such as being able to be attached to the member 2 with one touch.
