Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching electrical components, such as fluorescent display tubes, to a printed circuit board at regular intervals.

Generally, other electrical components of the IC cape are placed below this type of electrical component, so the terminals are formed long and attached to the printed circuit board at regular intervals. Conventionally, this type of installation method involves covering the terminal of an electrical component with a plastic tube, inserting the terminal into a mounting hole provided on a printed circuit board, and then fixing the terminal end tube to the printed circuit board by soldering. There are things that are done.

However, since this method uses a tube as a spacer member, it not only increases the number of parts and costs, but also makes the work of covering the terminal with the tube complicated and time-consuming. It's inconvenient. Furthermore, soldering has the disadvantage that the tube is deformed by heat when it is fixed.

The present invention has been developed in view of these circumstances, and by cleverly utilizing the space of the printed circuit board and interposing spacers separated from the printed circuit board between the electrical components and the printed circuit board, The present invention provides a method for attaching electrical components that can be extremely easily attached to the top of the vehicle at regular intervals. Hereinafter, its configuration will be explained in detail with reference to embodiments shown in the drawings.

FIG. 1 is a plan view showing the entire printed circuit board according to the present invention. In these figures, the reference numeral 1 indicates a printed circuit board formed into a rectangular shape, and a plurality of mounting holes 2 for inserting the terminals of the electrical components are bored at equal intervals P at one longitudinal edge. has been done. Reference numeral 3 denotes a spacer that is integrally provided at both the left and right ends of the printed circuit board 1, and can be separated by U-shaped and L-shaped notch grooves 1 and 2 that are opened at the edges of the printed circuit board 1. It is composed of Through holes 4 having the same diameter as the mounting holes 2 are bored at intervals equal to the spacing P between the mounting holes 2 at a portion located on a line approximately bisecting the spacer 3I/i in the longitudinal direction. 5 is a dividing portion provided between the main body 1b of the printed circuit board 1 and the spacer 3, which is formed thin in the width direction;
A dividing hole 6 for facilitating division is bored at a portion located on the line where the spacer 3 is divided. 7 is a fluorescent display tube;

7. A slightly longer skin made of electrical parts from Go. is fixedly attached to the bullet board 1 by soldering. The electric components T of μ are mounted on the printed circuit board 1 through spacers 3 separated from the printed circuit board 1 so as to maintain a constant interval Hf. Electrical parts are stored.

Next, a method of attaching the stained component to the printed circuit board using the above structure will be explained. First, the spacer 3 is separated at the separation ss of the printed circuit board 1. Next, a portion of the terminals 1a on both sides of the electrical component 1 are passed through the through holes of the spacer 3, respectively. Thereafter, all the terminals T&O of the electric component T are inserted into the corresponding mounting holes 2 of the printed circuit board 1, and the ends of these terminals are fixed to the printed circuit board 1 by soldering.

In this way, the electrical components 7 are attached to the printed circuit board 1 via the spacers 3 with a constant interval H maintained therebetween.

Note that although this example shows a case in which a girder space [1] is installed at both ends of the printed circuit board 10 and is interposed between the electrical component 7 and the printed circuit board 1, the present invention is not limited to this. Instead, as shown in FIG. 1, a notch lct' is formed on the printed circuit board 1 depending on the positional relationship with other electrical components, so the cutout member thus formed can be used as a spacer. , this may be interposed between the electrical component 7 and the printed circuit board 1. In other words, the member used as a spacer may be any part of the printed circuit board 1 as long as it utilizes an extra portion of the printed circuit board 1.

As explained above, according to the present invention, the spacer is formed integrally with a part of the printed circuit board so that it can be separated by the notch groove force, and when the electrical component is attached to the printed circuit board, the spacer is separated from the printed circuit board. By using the mounting method of interposing this between the electrical part layer and the printed circuit board, the electrical components can be mounted extremely easily by keeping them on the printed circuit board for a certain period of time, and the work time required for the mounting can be shortened. can be measured. Furthermore, since an extra portion of the printed circuit board is used as a spacer, it is extremely economical, and costs can be reduced. Furthermore, since the spacer member is not thermally deformed as in the conventional case, terminals of electrical components can be soldered reliably.
