Description

[Detailed Description of the Invention] This invention relates to an electrical component holding device for electrical equipment.

A large number of electrical components (including electronic elements) are held on insulating substrates such as printed circuit boards of electrical equipment, but since they occupy separate mounting areas, it is difficult to effectively reduce the area of the insulating substrate. Can not.

Furthermore, the height dimensions of electrical components vary depending on the type.

Therefore, when a plurality of insulating substrates are stacked, a corresponding space is formed between the insulating substrates.

This idea was created in consideration of the above points, and when connecting and holding electrical components to an insulating board, it is possible to more effectively miniaturize the insulating board by effectively utilizing not only the flat surface but also the three-dimensional space. The purpose is to scale the electrical component holding device of electrical equipment.

This device is press-fitted into an insulating substrate that holds a plurality of electrical components close to each other by elastically bending inward into a holding hole formed between the electrical components. It has a V-shaped leg that is prevented from coming off by a stopper that projects from the end that projects from the holding hole, and a notch located at one end of the leg that allows other electrical components to be inserted into a part of the outer periphery. a supporting part that supports the electrical component while separating it from the insulating substrate by the inward bending action of the leg;
This device is characterized by providing a holder integrally formed of an elastic material.

Therefore, by inserting the legs into the holding holes of the insulating board, the inward bending action of the legs makes it possible to hold the electrical components floating above the insulating board, thereby insulating them from the electrical components held by the holder. The structure is such that the area of the insulating substrate can be made smaller than the total projected area of the electrical components directly connected and held on the substrate.

An embodiment of this invention will be explained based on the drawings.

1 is a printed circuit board which is an insulating substrate, and this printed circuit board 1 has a holding hole 2 formed therein.

Thus, a holder 3 is provided.

The holder 3 is made of elastic plastic, and has a supporting portion 5 that is curved in an arc formed integrally with one end of a leg 4 that expands in a square shape.

A notch 6 is formed at the upper end of the supporting portion 5, and a stopper 7 is formed at the base of the leg 4 so as to protrude from both sides.

In this arrangement, the electrical component 8 is inserted through the notch 6, and the leg 4 is press-fitted into the holding hole 2.

The legs 4 gradually bend inward, and the supporting portions 5 elastically clamp the electrical components 8.

At this time, the leg 4 expands slightly into a V-shape toward the top and does not become thinner due to the resistance of the electrical component 8, so the movement in the insertion direction is fixed, and the movement in the opposite direction is fixed by the stopper 7. be done.

Of course, the legs 4 may have a ■-shape in the free state and become parallel when inserted into the holding hole 2.

Even in this case, since the legs 4 are urged outward, the insertion depth into the holding hole 2 does not increase indefinitely under normal usage conditions.

Providing a stopper (not shown) facing the stopper 7 is convenient for reliably determining the insertion depth.

As shown in FIG. 2, if the printed circuit board 1 and holder 3 are placed in a case 9 and filled with compound, the movement of the holder 3 as well as other electrical components 10 and 11 can be fixed.

These electrical components 10 and 11 can be connected and held to the printed circuit board 1 while being arranged near both sides of the holding hole 2.

As long as the electrical components 10 and 11 are on both sides of the holding hole 2, no matter how close they are, they will not interfere with the electrical component 8 because the electrical component 8 is installed using the space.

Therefore, the area of the printed circuit board 1 can be made smaller than the total projected area of all the electrical components 8, 10, 11.

The difference becomes larger as the number of electrical parts increases.
In fact, it contributes to the miniaturization of electronic devices.

Further, when stacking several printed circuit boards 1, it is necessary to leave a space between them, but there are many types of electrical components, and some have a height greater than the holder 3.

Therefore, by using the holder 3, the three-dimensional space (
There is no inconvenience that the opposing distance between the printed circuit boards increases.

Note that by forming the notch 6, the work of inserting the electrical component 8 into the supporting portion 5 is facilitated, and the lead wire 8a will not be broken at this time.

Since this invention is constructed as described above, other electrical components can be attached to the insulating substrate via a holder between the electrical components directly held on the insulating substrate, thereby increasing the projected area of a large number of electrical components. It is possible to reduce the area of the insulating board and downsize the electrical equipment based on the sum total of It is effective.
