Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a board device in which a synthetic resin component mounting base is outsert molded onto a metal board, and in particular, it relates to a board device in which a component mounting base made of synthetic resin is outsert molded onto a metal board. The present invention relates to a board device that allows for position adjustment of parts to be attached.

(Summary of the invention) This invention eliminates the need to adjust the position of the parts after molding by outsert-molding the component mounting base and the engaging body that locks and holds the mounting base in any position on the substrate. The object of the present invention is to provide a substrate device that is inexpensive and easy to assemble.

(Prior Art) Conventionally, in various electronic devices such as audio equipment, a component mounting base is integrally provided on a metal substrate by outsert molding, and a component such as a switch is attached to the component mounting base. equipment is used.

(Problem to be Solved by the Invention) Generally, a component mounting base that is integrally provided on a board by outsert molding is fixed to the board, so it cannot be attached to other parts, such as operating members, while it is attached. When installing a component such as a switch that requires adjusting the positional relationship between the component mount and the switch, the component mount cannot adjust the position of the component by itself, and the distance between the component mount and the switch etc. It is necessary to adjust the position of the parts by providing a separate adjustment mechanism, which leads to an increase in the number of parts, a decrease in assembly workability, and a rise in costs.

(Means for Solving the Problems) The present invention was made with the aim of solving the above problems. An engaging body made of synthetic resin is provided on the metal substrate by outsert molding, and engages and disengages from the base using flexure, and locks and holds the component mounting base at an arbitrary rotational position by engagement.

(Function) Therefore, the position of the component can be adjusted by locking and holding the component mount at an arbitrary rotational position using the engaging body that is outsert-molded at the same time as the component mount, thereby eliminating the need for a separate adjustment mechanism in the past. be able to.

(Example) Hereinafter, the present invention will be described in detail according to an example shown in the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a metal base plate having round holes 4 and 5 for attaching a switch mount and an elastic piece.

2 is a switch mounting base (component mounting base) made of synthetic resin, consisting of a mounting part 2a to the board 1, a switch holding part 2b, and a protruding piece 2c having a gear part 7 at the tip for adjusting the position. . This switch mount 2
is provided on the substrate 1 by outsert molding using the round opening 4, and is rotatable around the mounting portion 2a.

Reference numeral 3 denotes an elastic piece (engaging body) made of synthetic resin that has a gear part 9 that meshes with a gear part 7 provided on the protruding piece 2c of the switch mounting base 2.
It is outsert molded at the same time as the switch mounting base 2.

Reference numeral 6 denotes a lease switch, which is attached to the holding portion 2b of the switch mounting base 2 by screws 8.
Next, in the circuit board device configured as described above, when adjusting the position of the leaf switch 6 attached to the switch mount 2, a rotational force in the direction of arrow A or B is applied to the switch mount 2. . Then, the elastic piece 3 bends in the direction of arrow C, and the engagement between the gear parts 7 and 9 is released, and the switch mounting base 2
is allowed to rotate, and the leaf switch 6 can be adjusted to any position.

When the rotational force applied to the switch mount 2 is released, the elastic piece 3 returns elastically in the direction of arrow D, and the gear parts 7 and 9 engage again to move the switch mount 2 and, by extension, the leaf switch 6 to any desired position. It will be locked and held.

(Effects of the invention) As described above, the invention, together with the parts mounting stand,
By providing the engaging body that locks and holds the mounting base in any rotational position on the board by outsert molding, the position of the component can be adjusted by rotating the component mounting base, and there is no need to provide a separate adjustment mechanism. This reduces the number of parts and improves assembly work.
An inexpensive substrate device can be provided.
