I had a difficult problem.

The present invention solves the above-mentioned problems, and provides a terminal block for mounting components on a printed circuit board that enables stable component mounting that is resistant to vibration and also allows the mounting height of components from the printed circuit board surface to be constant. The purpose is to

[Effect]

In the present invention, a mounted component is vertically placed on a component mounting section 10a that is placed in surface contact with the surface of a printed circuit board, and a component support section 10b supports the mounted component from the side and is mounted vertically. Connect one lead wire of the component to the long hole 1 of the component placement section 10a.
2, and then connect the other lead wire to the lead wire connection conductor provided inside the component support part, so it is possible to vertically mount the component on the printed circuit board more stably and resistant to vibration. Moreover, the mounting height of the components from the printed circuit board surface can be made constant.

FIG. 1 is a front view of a component mounting terminal block, FIG. 2 is a plan view thereof, FIG. 3 is a right side view, and FIG. 4 is a front view showing a state in which components are mounted.

In the figure, a component mounting terminal block 10 integrally formed of an insulating material such as plastic includes a component mounting portion 10a having a desired thickness d, and a component mounting portion 10a having a desired thickness d.
A component support part 10b of a desired height is provided at right angles to one end of the part a.

A detent pin 11 made of a metallic material is protruded from the lower surface of the other end of the component placement portion 10a, and a lead wire pullout pin 11 is provided in the center of the component placement portion 10a along its longitudinal direction. A long hole 12 is formed.

Further, a lead wire connection conductor 13 made of a metallic rod material is penetrated through the component support portion 10b along the longitudinal direction of the component support portion 10b and molded integrally with the component support portion 10b. It is prominent. A band attachment groove 14 for fixing components is formed on the outer surface of the component support portion 10b.

Component mounting terminal block 10 configured as described above
When mounting a component 15 such as a capacitor on the printed circuit board 1 using a Lead wire 1 protruding from

[Effect of idea]

As described above, according to the present invention, there is a component placement section installed in surface contact with the printed circuit board surface, a long hole formed in this placement section for drawing out lead wires, and one end of the component placement section. Since the terminal block for component mounting is constructed from a conductor for connecting lead wires that penetrates the vertical component support part in the longitudinal direction, it is possible to mount stable components that are resistant to vibrations, and also to attach the printed circuit board. This has the effect of keeping the component mounting height constant from the surface.
